Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In the related art, when assembling the lens in the lens barrel, a mode of overlapping layer by layer and integrally installing the lens in a specific sequence is generally adopted. When the liquid lens is installed, the liquid lens needs to be installed together with the traditional lens, and cannot be installed independently, so that the installation and the use are very inconvenient. In addition, since the optical elements in the lens barrel are installed in sequence, the imaging conditions should be satisfied when the optical elements are installed in order to satisfy the imaging requirements. When the position of one element is changed or the installation position is inaccurate, other elements can be installed inaccurately correspondingly, and the element has the characteristic of being pulled to start and then to be used for the whole body, so that the subsequent updating and replacing processes are complex, and the maintenance cost is high.

Referring to fig. 1 to 4, in order to solve the above technical problem, an embodiment of the present invention provides a lens barrel 110, where the lens barrel 110 includes a first cylinder 111, a connecting bracket 112, and a second cylinder 113. Wherein the first cylinder 111 has a first mounting region 1111 for mounting the optical element, the connection bracket has a receiving region 1124 for mounting the optical element, and the second cylinder 113 has a second mounting region 1131 for mounting the optical element. Meanwhile, the optical axis 114 of the second cylinder 113 coincides with the optical axis 114 of the first cylinder 111, and thus, the optical axis 114 of the optical element installed in the first cylinder 111 and the optical element installed in the second cylinder 113 naturally also coincide, which is beneficial to the cooperative imaging of the optical elements in the first cylinder 111 and the second cylinder 113.

It should be noted that the first mounting region 1111, the accommodating region 1124 and the second mounting region 1131 are regions artificially partitioned according to different functions inside the lens barrel 110, the size, shape and the like of each are not specifically limited, and they may be switched with each other as the usage scene and usage mode of the lens barrel 110 are changed, so that no obvious boundary exists between them. And optical axis 114 is an artificially defined virtual axis and is not some entity present in lens barrel 110. It is understood that when the optical device is installed in the lens barrel 110, the optical axis 114 of the optical device should coincide with the optical axis 114 of the lens barrel 110 to achieve a better optical effect.

Specifically, the connecting bracket 112 includes a connecting plate 1121 and two side wall plates 1122. The connection plate 1121 has a light-transmitting through hole 1123, one surface of the connection plate 1121 is connected to the image side end of the first cylinder 111, and the hole wall of the light-transmitting through hole 1123 is connected to the inner peripheral wall of the first cylinder 111. That is, the connection bracket 112 is connected to the first cylinder 111 through the connection plate 1121, and the light transmission through hole 1123 of the connection plate 1121 communicates the first mounting region 1111 of the first cylinder 111 with the receiving region 1124 of the connection bracket 112. Thus, the light passing through the first mounting region 1111 can enter the accommodating region 1124 through the light-transmitting through hole 1123, thereby facilitating the cooperation imaging of different optical elements in the lens barrel 110.

The two side wall plates 1122 are connected to the surface of the connection plate 1121 that is away from the first cylinder 111, the two side wall plates 1122 are oppositely disposed on two sides of the light-transmitting through hole 1123, and the object side end of the second cylinder 113 is connected to the two side wall plates 1122. That is, the connecting bracket 112 is connected to the second cylinder 113 through the side wall plates 1122, and since the two side wall plates 1122 are oppositely disposed at both sides of the light-transmitting through hole 1123, that is, a certain distance is provided between the two side wall plates 1122, the receiving area 1124 of the connecting bracket 112 and the second mounting area 1131 of the second cylinder are also connected. Thus, the first mounting region 1111, the accommodating region 1124 and the second mounting region 1131 in the lens barrel 110 are all communicated, and when the lens barrel 110 is mounted in a lens for imaging, light rays incident from the object side end of the lens barrel 110 sequentially pass through the first mounting region 1111 of the first cylinder 111, the light-transmitting through hole 1123 on the connecting plate 1121, the accommodating region 1124 of the connecting bracket 112, the second mounting region 1131 in the second cylinder 113, and finally irradiate the image side end of the lens barrel 110.

Meanwhile, since the two side wall plates 1122 are disposed at two opposite sides of the light-transmitting through hole 1123, that is, a certain distance is provided between the two side wall plates 1122, outside the lens barrel 110, one end of the two side wall plates 1122 in the same direction, the connecting plate 1121 and the second cylinder 113 together define the first inserting groove 115, and the first inserting groove 115 is communicated with the accommodating area 1124. The first inserting groove 115 is a communication port between the accommodating area 1124 and the outside, and the optical element to be mounted in the accommodating area 1124 can gradually pass through the first inserting groove 115 from the outside of the lens barrel 110 and then enter the accommodating area 1124 without passing through the first barrel 111 or the second barrel 113, so that the optical element in the first mounting area 1111 and the second mounting area 1131 is not affected or interfered. Here, the optical element may be mounted manually or automatically by a power device. Thus, the optical elements in the first cylinder 111, the connecting bracket 112 and the second cylinder 113 can be independently installed in respective areas without interference, and the installation is convenient and efficient. Moreover, the optical elements and the lens barrel 110 are relatively independent in installation and fixation, so that even if the installation and fixation of one element are changed, accurate and effective imaging cannot be realized, other optical elements do not need to be moved or even damaged in subsequent replacement, and only corresponding element parts need to be moved or replaced, so that the process steps are greatly reduced and simplified, and the cost is greatly reduced.

By adjusting the positional relationship between the connection plate 1121 and the two side wall plates 1122, the volume of the housing section 1124 can be changed. For example, the two side wall plates 1122 are moved away from the centers of the accommodating sections 1124, respectively, while the connecting plates 1121 are adjusted in size so that the connecting plates 1121 remain connected to the two side wall plates 1122. Thus, the space at the surrounding position between the connection plate 1121 and the sidewall plate 1122 is increased, which plays a role of expanding the accommodation region 1124, so that the connection bracket 112 can accommodate optical elements with larger size, and the applicable scene range of the lens barrel 110 is widened. In contrast, when the size of the optical element to be accommodated in the connecting bracket 112 is small, the two side wall plates 1122 are moved toward the center of the accommodating section 1124 respectively, and at the same time, the size of the connecting plate 1121 is adjusted so that the connecting plate 1121 and the two side wall plates 1122 are still in the connecting relationship. Thus, the volume of the accommodating area 1124 is reduced, and the size of the lens barrel 110 is reduced, thereby reducing the processing difficulty and the processing cost.

When the optical element passes through the first insertion groove 115 and is disposed in the receiving area 1124, the optical element may be balanced and stabilized by virtue of its support force by the first insertion groove 115 (of course, in other embodiments, the optical element may be supported by other components). In order to firmly fix the optical element, a flange portion having a bearing surface formed by extending the outer side wall of the lens barrel 110 in a direction away from the receiving area 1124 may be disposed on the outer side wall of the lens barrel 110 near the first inserting groove 115, and the optical element may be fixed to the bearing surface by bonding or other similar methods. When the wall of the lens barrel 110 is thick enough, the bottom wall of the first insertion groove 115 can be used as a bearing surface to fix the optical element, and at this time, it is no longer necessary to fix the optical element by means of the flange portion. When it is desired to remove the optical element, the optical element can be removed from the first mating groove 115 by following the reverse path of the optical element when it is installed.

In one embodiment, the other end of the two side wall plates 1122, which are in the same direction, together with the connecting plate 1121 and the second cylinder 113, define the second insertion groove 116. Similarly, since the two side wall plates 1122 are disposed at two opposite sides of the light-transmitting through hole 1123, that is, a certain distance is provided between the two side wall plates 1122, at the other side of the exterior of the lens barrel 110, the other ends of the two side wall plates 1122 in the same direction, the connecting plate 1121 and the second barrel 113 jointly define the second inserting-connecting groove 116, the second inserting-connecting groove 116 is communicated with the accommodating area 1124, and a connecting line between the center of the second inserting-connecting groove 116 and the center of the first inserting-connecting groove 115 intersects the optical axis 114 in the lens barrel 110. Thus, as the optical element is inserted into receptacle 1124 during installation, one end of the optical element can be carried on second mating groove 116. Similarly, a flange portion may be disposed on the outer sidewall of the lens barrel 110 near the second inserting groove 116, and the flange portion has a bearing surface formed by extending the outer sidewall of the lens barrel 110 in a direction away from the receiving area 1124, and the optical element may be fixed on the bearing surface by bonding or other similar methods. At this time, the two ends of the optical element are respectively supported by the first insertion groove 115 and the second insertion groove 116, so that balance and stability can be maintained. When the optical element needs to be removed, the optical element can be taken out from the position of the first insertion groove 115 along the reverse path when the optical element is installed, and the optical element can be taken out from the position of the second insertion groove 116 along the path of the line connecting the center of the second insertion groove 116 and the optical axis 114. At this time, the first insertion groove 115 and the second insertion groove 116 respectively function as an installation entrance and a removal exit, and the installation and removal operations are more flexible.

Since the first inserting groove 115 and the second inserting groove 116 are defined by the two side wall plates 1122, the connecting plate 1121, and the second cylinder 113, the first inserting groove 115 and the second inserting groove 116 are respectively located on two opposite sides of a plane passing through the optical axis 114 of the lens barrel 110, that is, a connecting line between the center of the second inserting groove 116 and the center of the first inserting groove 115 intersects the optical axis 114 in the lens barrel 110, where the center refers to a centroid of the inserting groove. It should be noted that, since two ends of the optical element can be fixed at different positions on the first inserting groove 115 and the second inserting groove 116, even if a connecting line between the center of the second inserting groove 116 and the center of the first inserting groove 115 is not perpendicular to the optical axis 114 in the lens barrel 110, the optical element can be fixed in a state of being perpendicular to the optical axis 114 in the lens barrel 110, and the normal use of the optical element is not affected. For example, in a direction parallel to the optical axis 114 of the lens barrel 110, the center of the first inserting groove 115 is closer to the object side end of the lens barrel 110 than the center of the second inserting groove 116, and at this time, a connection line between the center of the second inserting groove 116 and the center of the first inserting groove 115 is not perpendicular to the optical axis 114 in the lens barrel 110, but only the optical element needs to be fixed in the position closer to the object side end of the lens barrel 110 in the second inserting groove 116, so that the difference between the center of the first inserting groove 115 and the center of the second inserting groove 116 from the object side end of the lens barrel 110 can be compensated.

When the line connecting the center of the second inserting groove 116 and the center of the first inserting groove 115 is perpendicular to the optical axis 114 in the lens barrel 110, two ends of the optical element may be fixed at corresponding positions on the first inserting groove 115 and the second inserting groove 116, for example, two ends are fixed on the bottom walls of the first inserting groove 115 and the second inserting groove 116, which is convenient for practical operation.

The lens barrel 110 includes a light entrance 117 at the object side. As is well known to those skilled in the art, the object side is a side of the lens barrel 110 close to the object, and the image side is a side of the lens barrel 110 far from the object. The light reflected by the object on the object side needs to enter the lens barrel 110 before being sensed by the optical elements in the lens barrel 110. Therefore, the object side of the lens barrel 110 is provided with an optical inlet 117. By adjusting the size of the light inlet 117, the amount of light entering the lens barrel 110 can be changed. In one embodiment, the first mounting region 1111 and the accommodating region 1124 in the lens barrel 110 are arranged as follows: the first mounting region 1111 is located between the accommodating region 1124 and the light entrance 117 in a direction parallel to the optical axis 114 in the lens barrel 110. That is, the light inlet 117, the first mounting region 1111 and the accommodating region 1124 of the lens barrel 110 are sequentially arranged from the object side to the image side of the lens barrel 110, and at this time, the light entering the lens barrel 110 from the light inlet 117 first passes through the optical elements in the first mounting region 1111 and then passes through the optical elements in the accommodating region 1124. In other embodiments, the arrangement order of the first mounting region 1111 and the accommodating region 1124 may be different, and the order of light entering the lens barrel 110 through the light inlet 117 passing through different optical elements may also be different.

And the arrangement relationship between the second installation region 1131 and the first installation region 1111 and the accommodation region 1124 may be: the accommodation region 1124 is located between the first mount region 1111 and the second mount region 1131 in a direction parallel to the optical axis 114 within the lens barrel 110. That is, the first mounting region 1111, the accommodating region 1124 and the second mounting region 1131 are sequentially distributed from the object side to the image side of the lens barrel 110, and at this time, the light entering the lens barrel 110 from the light inlet 117 first passes through the optical elements in the first mounting region 1111, then passes through the optical elements in the accommodating region 1124, and then passes through the optical elements in the second mounting region 1131. In other embodiments, the three regions may be arranged in different orders, and the order of light entering the lens barrel 110 through the light inlet 117 passing through different optical elements may also be different. In order to accommodate a greater number of optical elements, the lens barrel 110 may be further divided into more mounting regions. The arrangement of the installation areas is similar to that in the embodiment, and so on.

In order to save space in the lens barrel 110 and reduce the overall size of the lens barrel 110, and to make the lens barrel 110 have certain appearance identification and attraction, the diameter of the first cylinder 111 perpendicular to the optical axis 114 thereof is a first diameter, the diameter of the second cylinder 113 perpendicular to the optical axis 114 thereof is a second diameter, and the first diameter is smaller than the second diameter. I.e. in a direction parallel to the optical axis 114, from the first cylinder 111 to the connecting bracket 112 to the second cylinder 113, their size gradually increasing. At this time, the connecting bracket 112 plays a transition role between the first cylinder 111 and the second cylinder 113 with different sizes, and since the shape of the connecting bracket 112 may be any other shape than the cylinder shape of the first cylinder 111 and the second cylinder 113, compared with the cylinder shape with sequentially changed diameters, the connecting bracket 112 is simpler and more convenient to process and has lower cost. Moreover, no matter how large the difference value between the first diameter and the second diameter is, the connecting bracket 112 can well connect the first cylinder 111 and the second cylinder 113, so that the structure of the whole lens barrel 110 is more stable.

Referring to fig. 5 to 6, a second aspect of the present invention provides a lens barrel 100, where the lens barrel 100 includes a lens barrel 110, a first lens group 120, a liquid lens module 130, and a second lens group 140. The first lens group 120 includes at least one lens, and the first lens group 120 is disposed in the first mounting area 1111. The liquid lens module 130 is disposed in the accommodating area 1124. The second lens group 140 includes at least one lens, and the second lens group 140 is disposed at the second mounting area 1131. The lens 100 has a first lens group 120, a liquid lens module 130 and a second lens group 140, and accordingly, the lens barrel 110 of the lens 100 includes a first mounting area 1111 for accommodating the first lens group 120, an accommodating area 1124 for accommodating the liquid lens module 130 and a second mounting area 1131 for accommodating the second lens group 140. When more lens groups are needed in the lens 100, the lens barrel 110 with more mounting areas is only needed.

It should be noted that the lenses in the first lens group 120 and the second lens group 140 may be lenses made of glass or resin materials, which are commonly used in the art, and the lenses may be classified into convex lenses, concave lenses, etc. according to their shapes and functions. When the first lens group 120 or the second lens group 140 includes a plurality of lenses, the types, shapes, sizes, and the like of the lenses may be completely the same, may be partially the same, or may be different from each other. The lenses may be sequentially stacked and mounted in the corresponding mounting areas to cooperatively complete the imaging operation of the lens 100.

With the lens 100 of the present embodiment, the liquid lens module 130 in the lens 100 can pass through the first inserting groove 115 and be disposed in the accommodating area 1124, and does not need to be installed together with the first lens group 120 and the second lens group 140, so that the installation and the use are convenient and fast. Moreover, the lens group and other optical elements possibly existing in the lens 100 are relatively independent from the body of the lens barrel 110 in terms of installation and fixation, so that even if the installation and fixation of a certain element are changed, accurate and effective imaging cannot be achieved, and during subsequent replacement, other optical elements do not need to be moved or even damaged, and only the corresponding element part needs to be moved or replaced, thereby greatly reducing and simplifying the process steps and greatly reducing the cost.

Referring to fig. 7 to 11, a fourth aspect of the present invention provides a camera module 10, where the camera module 10 includes the lens 100 and the photosensitive chip 200 according to any of the embodiments. The light sensing chip 200 is used for sensing light passing through the lens 100 and performing imaging processing on the light.

The liquid lens module 130 includes a liquid lens 131 and a lens holder 132. The structure of the liquid lens 131 and the zooming principle when it is used are as follows: the liquid lens 131 includes a sealed cavity, and a conductive fluid and an insulating fluid filled in the sealed cavity, the conductive fluid and the insulating fluid being immiscible and separated by an interface therebetween, the conductive fluid and the insulating fluid having different refractive indices. When the liquid lens 131 is electrified by the electrode group, the conductive fluid inside the liquid lens generates an electrowetting effect to change a contact angle between the interface and the side wall of the closed cavity, so that the shape of the interface is changed, the light propagation direction is adjusted, and the requirements of focusing or anti-shaking are met. Therefore, the liquid lens 131 needs to be electrically connected to an electrode set or the like when being mounted. Therefore, in order to maintain the stability and the tight fixation of the liquid lens 131 during use, the liquid lens 131 needs to be mounted on the lens holder 132 and electrically connected to the lens holder 132. In one embodiment, the lens holder 132 includes a second conductive wire, and the liquid lens 131 is mounted on the lens holder 132 and electrically connected to the second conductive wire. Then, the lens holder 132 and the power device are electrically connected to maintain the normal working state of the liquid lens 131, and the camera module 10 further includes a wire holder 300, where the wire holder 300 includes a first wire. The lens barrel 110 is mounted on the wire holder 300, and the second wire is electrically connected to the first wire. Thus, the liquid lens 131 is finally connected to the lens barrel 110 through the second wire, the lens holder 132, the first wire and the wire holder 300 on the premise of ensuring the normal operation.

After the liquid lens module 130 is mounted to the accommodating area 1124 through the first inserting groove 115, in order to enable the liquid lens module 130 to have better optical performance, the liquid lens module 130 needs to be positioned so that the optical axis 114 of the liquid lens 131 coincides with the optical axis 114 of the lens barrel 110. Thus, in one embodiment, the side wall plate 1122 is provided with a stop at an end remote from the first mating groove 115. When the lens holder 132 of the liquid lens module 130 carries the liquid lens 131 from the first inserting groove 115 into the accommodating area 1124, the blocking piece can block the movement of the lens holder 132, so that the liquid lens module 130 stays at a specific position, and when the liquid lens 131 is at the specific position, the optical axis 114 of the liquid lens 131 coincides with the optical axis 114 of the first lens group 120. Therefore, the liquid lens module 130 can be positioned in the accommodating area 1124 by the blocking block, so that the optical axis 114 of the liquid lens 131 coincides with the optical axis 114 of the first lens group 120, and the liquid lens module 130 can have better optical performance.

It is understood that in other embodiments, the liquid lens module 130 can be positioned in other different manners to enable the liquid lens module 130 to have better optical performance. For example, the lens holder 132 is provided with a first magnetic attraction portion, and the connecting holder 112 is provided with a second magnetic attraction portion facing the accommodating area 1124. In the process that the lens holder 132 of the liquid lens module 130 carries the liquid lens 131 from the first inserting groove 115 into the accommodating area 1124, the first magnetic attraction portion and the second magnetic attraction portion are attracted together by the magnetic force, so that a resistance is applied to the lens holder 132 to make it stay at a specific position, and when the liquid lens 131 is at the specific position, the optical axis 114 of the liquid lens 131 coincides with the optical axis 114 of the first lens group 120. Therefore, the position of the liquid lens module 130 in the accommodating area 1124 can be located by the first magnetic portion and the second magnetic portion, so that the optical axis 114 of the liquid lens 131 coincides with the optical axis 114 of the first lens group 120, and the liquid lens module 130 can have better optical performance.

It should be noted that, since the positioning is realized by the attraction between the first magnetic attraction portion and the second magnetic attraction portion, the positions of the first magnetic attraction portion on the lens holder 132 and the second magnetic attraction portion on the connecting holder 112 are not particularly limited, and may be selected in various ways, only by positioning the first magnetic attraction portion and the second magnetic attraction portion at corresponding positions. For example, the first magnetic attraction portion is located at a position on the lens holder 132 close to the first insertion groove 115, and correspondingly, the second magnetic attraction portion is located at a position on the connecting holder 112 far from the end inserted into the first insertion groove 115, so that when the first magnetic attraction portion and the second magnetic attraction portion are attracted, the liquid lens module 130 can be positioned, and the optical axis 114 of the liquid lens 131 coincides with the optical axis 114 of the lens barrel 110. Similarly, there are other options for the position of the first magnetic attraction part on the lens holder 132 and the position of the second magnetic attraction part on the connecting holder 112.

The camera module 10 further includes a filter 400, and the filter 400 is used for filtering light rays emitted to the photosensitive chip 200. The filter 400 may be selected from a range of wavelength bands of the projected light, and the principle of the filter is to isolate the light of a certain wavelength band and transmit the light of the other wavelength bands, and is generally made of a transparent optical material such as glass or synthetic resin. Add light filter 400 in the module of making a video recording 10, can completely cut off certain colour and disturb, make the formation of image effect purer. The lens holder 132 has an opening 1321, the filter 400 is connected to a surface of the lens holder 132 away from the liquid lens 131, and the filter 400 covers the opening 1321. Thus, the filter 400 is located between the liquid lens 131 and the lens holder 132 in the camera module. The light beam passing through the liquid lens 131 passes through the opening 1321 of the lens holder 132 and the filter 400 in sequence, and finally irradiates the surface of the photo chip 200.

Further, the optical filter 400 and the opening portion 1321 together define an accommodating cavity, the accommodating cavity is used for accommodating the liquid lens 131, and the liquid lens 131 is carried by the optical filter 400. By accommodating the liquid lens 131 in the accommodating cavity, the space occupied by the liquid lens 131 can be saved, so as to reduce the size of the whole camera module 10.

Since the liquid lens module 130 is disposed in the accommodating area 1124 after being mounted, the lens holder 132 is also located in the accommodating area 1124, and at this time, in order to eliminate the shaking of the liquid lens 131 caused by the vibration of the lens barrel 110 to a certain extent, in an embodiment, the lens holder 132 further includes a connecting portion 1322, the lens holder 132 is disposed behind the accommodating area 1124, the connecting portion 1322 extends out of the accommodating area 1124 to be connected with the wire holder 300, the connection portion 1322 realizes the support and transmission between the inside and the outside of the accommodating area 1124, and the liquid lens 131 is connected with the external wire holder 300, so that the influence on the liquid lens 131 caused by the vibration of the lens barrel 110 can be reduced to a certain extent. The size and shape of the connecting portion 1322 are not limited, but in order to better support the lens holder 132, the connecting portion 1322 may be protruded at both ends of the lens 100, and the protruding direction is perpendicular to the optical axis 114.

Since the lens holder 132 is installed in the receiving area 1124, and the receiving area 1124 is open to the outside only at the positions of the first inserting groove 115 and the second inserting groove 116, the connecting portion 1322 of the lens holder 132 can be extended from the position of the inserting groove to connect with the lead frame 300. Meanwhile, in consideration of the stability of the lens holder 132, the connection part 1322 may protrude from the first insertion groove 115 and the second insertion groove 116. Therefore, in one embodiment, the lens holder 132 includes two connecting portions 1322, wherein one connecting portion 1322 extends out of the first plugging groove 115 to connect with one end of the wire holder 300, and the other connecting portion 1322 extends out of the second plugging groove 116 to connect with the other end of the wire holder 300. In this way, the two connecting portions 1322 extend from the openings at the two ends of the accommodating area 1124 respectively to connect with the wire holder 300, so as to support the lens holder 132 more stably and firmly.

After the lens holder 132 is mounted in the accommodating area 1124 defined by the connecting holder 112, the lens holder 132 can be completely fixedly connected with the connecting holder 112 in the lens barrel 110, but not connected with the lead holder 300 outside the lens barrel 110; the lens holder 132 may be completely connected to the wire holder 300 outside the lens barrel 110, instead of being fixedly connected to the lens barrel 110. Since the structural stability of the wire holder 300 outside the lens barrel 110 is stronger, the wire holder is less likely to be affected by external influences to vibrate, so that the working state of the liquid lens 131 is more stable and is not affected. Therefore, in one embodiment, the lens holder 132 is supported by the wire holder 300 through the two connecting portions 1322, so that the lens holder 132 is suspended in the accommodating area 1124. That is, the lens holder 132 is completely connected to and supported by the wire holder 300 without physically contacting the connection holder 112 of the lens barrel 110. Therefore, when the lens barrel 110 vibrates under the influence of an external force, the liquid lens 131 is not driven to vibrate, and the stability of the liquid lens 131 during operation is better.

The required wire that uses of electrical connection has multiple form, and the wire that traditional metal wire was made can cause the interior mixed and disorderly sense of appearance of camera module 10 to arouse the inconvenient dismouting or the change of spare part because length misuse still can lead to appearing the shadow of wire before camera lens 100 to influence image quality. Thus, in one embodiment, the first wire comprises a first electrical body 310 and a second electrical body 320, the first electrical body 310 being arranged adjacent to the first jack slot 115 and the second electrical body 320 being arranged adjacent to the second jack slot 116.

The wire in this embodiment all adopts the form of two liang of continuous electric bodies, can not cause to make a video recording and take a photograph of and to appear mixed and disorderly sense in the module 10, and the dismouting of spare part is changed conveniently. And the electric body does not appear in front of the lens 100 to cause a shadow to affect the imaging quality.

After the second conductive traces on the lens holder 132 are in the form of electrical bodies, the lens holder 132 is electrically connected to the conductive trace holder 300 through the third electrical body 1323 and the fourth electrical body 1324. And just the lens holder 132 is further provided with a connecting portion 1322 for fixing and supporting with the wire holder 300, at this time, if the third electrical body 1323 and the fourth electrical body 1324 can be integrated with the connecting portion 1322, the number of parts in the camera module 10 can be reduced, and the cost is saved and the probability of failure of the parts can be reduced. Therefore, in one embodiment, the third electrical body 1323 and the fourth electrical body 1324 are both used as the connecting portion 1322. The third electrical component 1323 extends out of the first plugging slot 115 to be electrically connected to the first electrical component 310, the fourth electrical component 1324 extends out of the second plugging slot 116 to be electrically connected to the second electrical component 320, and the third electrical component 1323 and the fourth electrical component 1324 are also used as a connecting portion 1322 to be connected and supported with the wire holder 300.
