The connecting component A of the utility model is used for providing an electric connecting terminal B for insertion. The connection assembly a comprises: an inner conductive member 1, a main conductor 2, a first insulating holder 3 and a second insulating holder 4.

The inner conductive member 1 is bent from a conductive sheet body into a cylindrical shape, and the inner conductive member 1 is correspondingly formed with a conductive hole 1A. The inner conductive member 1 comprises a body 10 and a plurality of cantilevers, one end of each cantilever is connected to the body 10, the other end of each cantilever is a free end, and each cantilever can be elastically deformed when pressed.

The main conductor 2 has a one-piece structure. The main conductor 2 includes a through hole 21 and four main fixing structures 22. The through hole 21 is provided through the main conductor 2. The through hole 21 is used for providing penetration of the inner conductive member 1. As shown in fig. 2 and 3, in practical application, the conductive sheet may be bent into a cylindrical shape to form the inner conductive member 1, and then the inner conductive member 1 may be inserted into the through hole 21. When the inner conductive member 1 is disposed in the through hole 21, the elastic restoring force generated by the bending of the conductive sheet body will fix the inner conductive member 1 in the through hole 21. When the main conductor 2 is fixedly provided in the through hole 21, the main conductor 2 is brought into contact with the main conductor 2, and thus both are brought into an electrically connected state.

The four main fixing structures 22 may be, for example, through holes penetrating the main conductor 2, and the apertures of the four main fixing structures 22 are smaller than the apertures of the through holes 21, the four main fixing structures 22 may be disposed around the through holes 21, and the four main fixing structures 22 may be disposed at four corners of a virtual rectangle. In practical applications, the number, size and arrangement of the main fixing structures 22 are not limited to those shown in the drawings.

The main conductor 2 further comprises a connection portion 23, and the connection portion 23 is configured to be fixed to an inner conductor C1 of an electric wire C. In the present embodiment, the connection portion 23 is taken as an example of an empty area, but the form of the connection portion 23 is not limited thereto. In practical applications, the shape of the connection portion 23 may be changed according to the connection manner of the connection portion 23 and the electric wire C.

The first bases 31 are, for example, rectangular sheet structures, one end of each first guide wall 32 is connected to the first base 31, and each first guide wall 32 may be substantially in an arc-shaped wall structure. One end of each first guide wall 32 is spaced apart from one end of the other first guide wall 32. The two first guide walls 32 and a first base through hole 311 of the first base 31 together form a first through hole 33. Each of the first guide walls 32 may have a first terminal guiding structure 321 at an end opposite to the first base 31. When the electrical connection terminal B (as shown in fig. 1) is inserted into the first insulating fixture 3 from the end of the first insulating fixture 3 having the first terminal guiding structures 321, the two first terminal guiding structures 321 will guide the electrical connection terminal B into the first through hole 33, and the two upper guiding walls 32 may be slightly elastically deformed, for example, so designed that the electrical connection terminal B can more easily enter the first through hole 33.

Each of the first fixing structures 34 is, for example, a substantially cylindrical structure, one end of each of the first fixing structures 34 is connected to the first base 31, and two of the first fixing structures 34 may be disposed at diagonal positions of the first base 31.

The second insulating fixing member 4 includes a second base 41, two second guide walls 42, a second through hole 43, two second fixing structures 44, and two second auxiliary fixing structures 45. The second bases 41 are, for example, rectangular sheet structures, one end of each second guide wall 42 is connected to the second base 41, and each second guide wall 42 may be substantially in an arc-shaped wall structure. One end of each second guide wall 42 is spaced apart from one end of the other second guide wall 42. The two second guide walls 42 and a second base through hole 411 of the second base 41 together form a second through hole 43. Each second guide wall 42 may have a second terminal guiding structure 421 at an end opposite to the second base 41. When the electrical connection terminal B (as shown in fig. 1) is inserted into the second insulating fixture 4 from the end of the second insulating fixture 4 having the second terminal guiding structure 421, the two second terminal guiding structures 421 will guide the electrical connection terminal B into the second through hole 43, and the two second guiding walls 42 may be slightly elastically deformed, for example, so designed that the electrical connection terminal B can more easily enter the second through hole 43.

Each of the second fixing structures 44 is, for example, a substantially cylindrical structure, one end of each of the second fixing structures 44 is connected to the second base 41, and two of the second fixing structures 44 may be disposed at diagonal positions of the second base 41. Each of the second auxiliary fixing structures 45 is, for example, a through hole penetrating the second base 41, and two of the second auxiliary fixing structures 45 may be disposed at another diagonal position of the second base 41.

As shown in fig. 1, 2 and 4, when the main conductor 2, the first insulating fixing member 3 and the second insulating fixing member 4 are assembled with each other, the two first fixing structures 34 of the first insulating fixing member 3 can correspondingly pass through two of the main fixing structures 22 (through holes) of the main conductor 2 and the two second auxiliary fixing structures 45 (through holes) of the second insulating fixing member 4, and the two second fixing structures 44 of the second insulating fixing member 4 can correspondingly pass through the other two main fixing structures 22 (through holes) of the main conductor 2 and the two first auxiliary fixing structures 35 (through holes) of the first insulating fixing member 3.

As described above, the first insulating fixing member 3 and the second insulating fixing member 4 can be respectively matched with the main fixing structure 22 of the main conductor 2 through the first fixing structure 34 and the second fixing structure 44, so as to be fixed on two sides of the main conductor 2, and the first fixing structure 34 and the second fixing structure 44 can be respectively matched with the second auxiliary fixing structure 45 and the first auxiliary fixing structure 35, so as to assist the connection strength of the first insulating fixing member 3, the main conductor 2 and the second insulating fixing member 4.

In practical applications, the first fixing structure 34, the main fixing structure 22, and the second auxiliary fixing structure 45 may be fixed to each other in a tight fit manner, and the second fixing structure 44, the main fixing structure 22, and the first auxiliary fixing structure 35 may be fixed to each other in a tight fit manner, but not limited thereto.

As shown in fig. 3, 4 and 6, in the assembly process of the connection assembly a, the inner conductive member 1 may be fixedly disposed in the through hole 21, and then the first insulating fixture 3 and the second insulating fixture 4 may be fixedly disposed at two sides of the main conductor 2, and the inner conductive member 1 may be accommodated in the first through hole 33 of the first insulating fixture 3 and the second through hole 43 of the second insulating fixture 4.

As shown in fig. 4 to 7, in the preferred embodiment, the end of the first insulating holder 3 having the first base 31 may further have a first insertion guiding structure 36. The first insertion guide structure 36 is used for guiding one end of the inner conductive member 1 that has been inserted into the through hole 21 into the first through hole 33. As shown in fig. 7, in the cross-sectional view of the first insulation fixing element 3, the first insertion guiding structure 36 may be, for example, an inclined plane, that is, the aperture 36D of the first insulation fixing element 3 in the section with the first insertion guiding structure 36 gradually decreases from one end of the first insertion guiding structure 36 away from the first guiding wall 32 to the other end, and the minimum aperture of the first insulation fixing element 3 in the section with the first insertion guiding structure 36 is larger than the aperture 21D of the through hole 21. In practical applications, the through holes 21 may be substantially the same in diameter in any of the sections.

The second insulating fixture 4 has a second insertion guiding structure 46 at one end of the second base 41, and the second insertion guiding structure 46 is used for guiding the other end of the inner conductive member 1 which is already inserted into the through hole 21 into the second through hole 43. As shown in fig. 7, in the cross-sectional view of the second insulating fixture 4, the second insertion guiding structure 46 may be, for example, an inclined plane, that is, the aperture 46D of the second insulating fixture 4 in the section with the second insertion guiding structure 46 gradually decreases from one end of the second insertion guiding structure 46 away from the second guiding wall 42 to the other end, and the minimum aperture of the second insulating fixture 4 in the section with the second insertion guiding structure 46 is larger than the aperture 21D of the through hole 21.

As shown in fig. 6 and 7, the aperture 33D of the first through hole 33 may be gradually reduced from the end close to the first base 31 to the end far from the first base 31, and the minimum aperture of the end of the first through hole 33 far from the through hole 21 may be larger than the aperture 21D of the through hole 21. The aperture 43D of the second through hole 43 may be gradually reduced from the end close to the second base 41 to the end far from the second base 41, and the minimum aperture of the end of the second through hole 43 far from the through hole 21 may be larger than the aperture 21D of the through hole 21.

As described above, by the design of the first insertion guide structure 36, the design of the second insertion guide structure 46, the aperture design of the first through hole 33 and the aperture design of the second through hole 43, the first insulating holder 3 and the second insulating holder 4 can be fixed to the main conductor 2 provided with the inner conductive member 1, and both ends of the inner conductive member 1 can more easily enter the first through hole 33 and the second through hole 43.

As shown in fig. 6, after the first insulating fixture 3, the main body 2, the inner conductive member 1 and the second insulating fixture 4 are fixed to each other, the first through hole 33, the second through hole 43 and the conductive hole 1A are communicated with each other to form a plugging hole, and the plugging hole is used for providing the electrical connection terminal B (shown in fig. 1) to be plugged. When the electrical connection terminal B is inserted into the jack hole, the plurality of cantilevers included in the inner conductive member 1 will abut against the outer side of the inner conductive member 1, and thus the electrical connection terminal B will be electrically connected with the inner conductor C1 (as shown in fig. 1) of the electric wire C through the inner conductive member 1 and the main conductor 2.

As shown in fig. 6 and 7, in practical application, a side of each first guide wall 32 away from the first base 31 may be further formed with a first limiting structure 37. Specifically, each first guide wall 32 extends inward away from the end of the first base 31 to form a first limiting structure 37. Each second guide wall 42 may be formed with a second limit structure 47 on a side away from the second base 41. Specifically, each second guide wall 42 extends inward away from the end of the second base 41 to form a second limiting structure 47.

The first limiting structure 37 and the second limiting structure 47 are used for limiting the moving range of the inner conductive member 1 relative to the first insulating fixture 3 and the second insulating fixture 4, so as to prevent the inner conductive member 1 from separating from the first insulating fixture 3 or the second insulating fixture 4 in the process that the electrical connection terminal B leaves the connection assembly a.

It should be noted that, in one practical application, the first insulating fixing member 3 and the second insulating fixing member 4 may be identical components, so that the cost of production and manufacture can be reduced, but not limited thereto. In different embodiments, the first insulating holder 3 and the second insulating holder 4 may be different members.

In summary, the connection assembly of the present utility model is designed by the main conductor, the first insulating fixing member, the second insulating fixing member, the inner conductive member, etc., so that the user can simply modify the thickness of the main conductor, the size of the first insulating fixing member or the second insulating fixing member, and the connection assembly can meet the size requirement of the electrical connection terminal.

Please refer to fig. 8, which is a schematic diagram of a second embodiment of the connecting assembly of the present utility model. The present embodiment is most different from the foregoing first embodiment in that: the length of the inner conductive member 1B of the connection assembly A1 may be slightly greater than that of the main conductor 2, and two ends of the inner conductive member 1B may be the first limiting structure 37 of the first insulating fixture 3 and the second limiting structure 47 of the second insulating fixture 4 that are not abutted against. That is, in practical applications, the relevant technician may adjust the length of the inner conductive member 1B according to the practical requirements (such as the length of the electrical connection terminal, etc.), and since the inner conductive member 1B is formed by bending the conductive sheet, the inner conductive member 1B can be stably fixed in the through hole 21 even if the inner conductive member 1B is not in contact with the first insulating fixture 3 or the second insulating fixture 4. In the non-illustrated part of this embodiment, please refer to the aforementioned first embodiment, and the description thereof is omitted.

Please refer to fig. 9, which is a schematic diagram of a third embodiment of the connecting assembly of the present utility model. The present embodiment is most different from the foregoing first embodiment in that: the main conductor 2A of the connection assembly A2 is relatively thin, and the length of the second insulating fixture 4A is relatively long, while one end of the inner conductive member 1 in the second insulating fixture 4A is not abutted against the second limiting structure. That is, since the thickness of the main conductor 2A, the length of the second insulating fixture 4A and the length of the first insulating fixture 3 included in the connection assembly A2 of the present utility model can be changed according to practical requirements. In the non-illustrated part of this embodiment, please refer to the aforementioned first embodiment, and the description thereof is omitted.

Please refer to fig. 10, which is a schematic diagram of a fourth embodiment of the connecting assembly of the present utility model. The present embodiment is most different from the foregoing first embodiment in that: the connection portion 23A of the connection assembly A3 includes at least two holding structures 231, and the two holding structures 231 are used to hold the inner conductor C1 of the electric wire C together, so that the inner conductor C1 of the electric wire C can be electrically connected with the main conductor 2. The shape and arrangement of the two holding structures 231 are not limited to those shown in the drawings. In the non-illustrated part of this embodiment, please refer to the aforementioned first embodiment, and the description thereof is omitted.

Similarly, the body 10 is formed with a second cantilever 12 (i.e. one of the cantilevers described in the previous embodiment) extending from a second sidewall 102a forming each second cutout 102 toward the second side 10b and away from the body 10, the second sidewall 102a with the second cantilever 12 extending therefrom is adjacent to the second side 10b, and the orthographic projection area of the second cantilever 12 toward the body 10 correspondingly falls into the second cutout 102. In a specific implementation, the first cantilevers 11 and the second cantilevers 12 are integrally formed with the body 10, and the first cantilevers 11 and the second cantilevers 12 may be die-cut along the outer contours of the first cutouts 101 and the second cutouts 102 of the body 10.

As shown in fig. 11 and 13, each first cantilever 11 defines a first rising section 111, a first contact section 112 and a first falling section 113, wherein each first rising section 111 is formed by extending a first sidewall 101a forming each first cutout 101 toward the second side 10b and away from the body 10, each first contact section 112 is formed by extending each first rising section 111 toward the second side 10b, and each first falling section 113 is formed by extending each first contact section 112 toward the second side 10b and toward the body 10. Similarly, each second cantilever 12 defines a second rising section 121, a second contact section 122 and a second falling section 123, and each second rising section 121 is formed by extending a second sidewall 102a forming each second cutout 102 in the direction of the first side 10a and the direction away from the body; each second contact section 122 is formed by extending each second rising section 121 toward the first side 10 a; each second descending section 123 is formed by extending each second contact section 122 toward the first side 10a and the direction approaching the body 10. In practical applications, each of the first cantilevers 11 and each of the second cantilevers 12 may have the same shape.

In practical applications, the orthographic projection length L2 of each first descending section 113 toward the body 10 may be one third of the orthographic projection length L1 of each first cantilever 11 toward the body 10, and the vertical distance H1 between each first contact section 112 and the body 10 may be the maximum vertical distance between each first cantilever 11 and the body 10. Similarly, the orthographic projection length L4 of each second descending section 123 toward the body 10 may be one third of the orthographic projection length L3 of each second cantilever 12 toward the body 10, and the vertical distance H2 between each second contact section 122 and the body 10 may correspond to the maximum vertical distance between each second cantilever 12 and the body 10. Through the above design, the first contact sections 112 and the second contact sections 122 are located on different axes AX1, AX2 (as shown in fig. 11), that is, the first contact sections 112 and the second contact sections 122 adjacent to each other are staggered with each other, and a distance D exists between each first contact section 112 and each second contact section 122 as seen from the side view of the body 10 (as shown in fig. 14).

Any position of each first rising section 111 may have the same width, and the width of each first falling section 113 may be gradually reduced from one end adjacent to the first contact section 112 to one end adjacent to the second side 10 b. Similarly, any position of each second rising section 121 may have the same width, and the width of each second falling section 123 may be gradually reduced from one end adjacent to the second contact section 122 to one end adjacent to the first side 10 a. By this design, the most first cantilever 11 and the most second cantilever 12 can be formed in the same size body 10. As shown in fig. 13, the angle θ1 between the opposite sides of the first lowering section 113 and the central axis CX1 of the first lowering section 113 may be adjusted according to the requirement; the included angle θ2 between the opposite sides of the second descending section 123 and the central axis CX2 of the second descending section 123 can be adjusted according to the requirement; specifically, the smaller the included angles θ1, θ2, the smaller the insertion force required when the electrical connection terminal B is inserted into the inner conductive member 1 (as shown in fig. 15).

As shown in fig. 13, it is specifically explained that the maximum width W5 of the first cantilever 11 is smaller than the maximum width W1 of the first root region 1011. The maximum width W6 of the second cantilever 12 is smaller than the maximum width W3 of the second root region 1021. Thus, after a long time use, the first cantilevers 11 (the second cantilevers 12) are not likely to be tilted by the external force applied to the first cantilevers 11 (the second cantilevers 12) and interfere with the body 10 at the positions where the first cantilevers 11 (the second cantilevers 12) are connected to the body 10. In practical applications, the width W5 of each first rising section 111 may be three fifths of the width W1 of each first root region 1011, and the distances W7, W8 between the opposite sides of the first rising section 111 and the opposite sides forming the first root region 1011 (e.g., one fifth of the width W1 of each first root region 1011) may be substantially equal. Similarly, the width W6 of each second rising section 121 toward the body 10 may be three fifths of the width W3 of each second root region 1021, and the distances W9, W10 of the opposite sides of the second rising section 121 from each other and the opposite sides forming the second root region 1021, respectively (e.g., one fifth of the width W3 of each second root region 1021) may be substantially equal.

In practical implementation, the difference between the width W1 of each first root region 1011 and the width W5 of each first rising section 111 may be substantially equal to the minimum distance W11 between the first notch 101 and the second notch 102 adjacent to each other. Similarly, the width of each second root region 1021 and the width W6 of each second rising section 121 may be substantially equal to the distance W11 between adjacent first and second slits 101 and 102.

Referring to fig. 14, in the embodiment, an included angle θ3 between each first falling section 113 and the horizontal line is larger than an included angle θ4 between each second rising section 121 and the horizontal line, and an included angle θ5 between each second falling section 123 and the horizontal line is larger than an included angle θ6 between each first rising section 111 and the horizontal line. By such a design, the insertion force required when the electric connection terminal is inserted into the two inner conductive members 1 can be effectively reduced.

As shown in fig. 15, when the electrical connection terminal B just enters between the two inner conductive members 1, the electrical connection terminal B will push against each first falling section 113 first because the angle between each first falling section 113 and the horizontal line is larger than the angle between each second rising section 121 and the horizontal line; the first descending section 113 against which the electrical connection terminal B is pushed is the position farthest from the position where the first cantilever 11 is connected to the body 10, so that the force applied to the first cantilever 11 by the electrical connection terminal B will generate a relatively large moment to the position where the first cantilever 11 is connected to the body 10, and the first cantilever 11 will be relatively easily pushed against and move toward the body 10.

In the state of fig. 15, since the second rising section 121 is closer to the electrical connection terminal B than the second falling section 123 and the second rising section 121 is closer to the position where the second cantilever 12 is connected to the body 10 than the second falling section 123, if the electrical connection terminal B pushes against the second rising section 121 in the state of fig. 15, the force acting on the second rising section 121 by the electrical connection terminal B will be relatively small, that is, the moment generated at the connection point of the second cantilever 12 to the body 10 will be relatively small, that is, the user must insert the electrical connection terminal with a larger force to move the second cantilever 12 toward the body 10. However, the inner conductive members 1 of the present utility model have the included angle between each first falling section 113 and the horizontal line greater than the included angle between each second rising section 121 and the horizontal line, so that the electrical connection terminal B will not push against the second cantilever 12 with relatively smaller force arm when just inserted between the two inner conductive members 1, and the electrical connection terminal B is the first cantilever 11 with relatively larger force arm correspondingly pushed against, thus reducing the insertion force required by the user to insert the electrical connection terminal B between the two inner conductive members 1, thereby being convenient for the user to operate; in contrast, the pulling force required by the user to pull out the electrical connection terminal B from between the two inner conductive members 1 can also be effectively reduced.

As described above, the inner conductive member 1 of the present embodiment allows the user to insert the electrical connection terminal B into the connection assembly a with a relatively small insertion force; in contrast, the user can pull out the electrical connection terminal B from the connection assembly a with a relatively small pull-out force; and through the design of a plurality of first contact sections and a plurality of second contact sections which are not positioned on the same axis, the biting force between the inner conductive member 1 and the electric connection terminal B can be improved, the safety of the inner conductive member 1 and the electric connection terminal B in power transmission is improved, the contact resistance between the inner conductive member 1 and the electric connection terminal B can be reduced, and the rising temperature value of the inner conductive member 1 and the electric connection terminal B in power transmission can be effectively reduced.

The foregoing description is only of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model, so that all equivalent technical changes made by the specification and drawings are included in the scope of the utility model.
