Description

Crimping pliers

Technical Field

The utility model relates to a crimping pliers.

Background

With the development of communication technology, most of the households are provided with the network. At present, internet access in a fixed area (such as a home environment or a company) is still mainly a wired network. That is, the signal must be transmitted through the network cable laid by the telecommunication company. In addition, the network cable needs to be electrically connected to the electronic device through a telecommunication connector (or called network terminal).

Fig. 1A is a schematic view of a basic type telecommunications connector, and fig. 1B and 1C are schematic views of an improved type telecommunications connector. Referring first to fig. 1A, the basic type of the telecommunications connector 9 includes a connection terminal 91 and a signal line 92. The conventional connection terminal 91 is a plastic housing, and the connection terminal 91 has a plurality of conductive plates 911 (or called gold plates) at the front end and a connection block 912 near the rear end. The signal line 92 is composed of a plurality of wire cores 921

(core 921 is shown in FIG. 1B) and the outer layer is wrapped with a non-conductive sheath 922. The distributor should arrange the plurality of cores 921 of the signal line 92 at the front ends of the connection terminals 91 to correspond to the conductive sheets 911 of the connection terminals 91, respectively. The conventional crimping pliers have a mold cavity and a toothed pressing plate, so that a wiring worker can place the connecting terminal 91 in the mold cavity and crimp the conductive sheet 911 and the wire core 921 through the toothed pressing plate. The conventional crimping pliers also have a flat pressing plate for crimping the connection block 912 and the housing 922 of the signal wire 92, thereby fixing the connection terminal 91 and the signal wire 92.

It should be noted that the front end of the connection terminal 91 of the basic type is closed, and it is necessary for the distributor to accurately arrange the wire core 921 at the front end of the connection terminal 91 and correspond to the conductive sheet 911. Accordingly, a modified type of telecommunications connector 9a is commercially available, which differs from the basic type of telecommunications connector 9 in that the front end of the housing of the connection terminal 91a has an opening 913a to allow the wire core 921 to pass outside the connection terminal 91 a. Therefore, the distributor can pull the wire core 921 out of the through connection terminal 91a first to facilitate the operation. Next, after the terminal 91a and the signal line 92 are connected to each other by crimping with a conventional crimper, the core 921 protruding from the terminal 91a is trimmed with another cutter.

Referring to fig. 1C, to achieve the shielding effect, there is a telecommunications connector 9b using a metal shell 93 b. The metal shell 93b is sleeved outside the connection terminal 91b, and the metal shell 93b has two extending portions 931b capable of winding around the housing 922 of the signal line 92, thereby fixing the connection terminal 91b and the signal line 92. The improved telecommunication connector 9 has a structure that the connection terminal 91b does not have the connection block 912. However, the conventional crimping pliers have a flat pressing plate and cannot be applied to the telecommunications connector 9 b. Specifically, only a crimping tong having a toothed press plate (without a flat press plate) can be used to crimp the telecommunications contact 9b, and it is also necessary to wind the extension 931 around the housing 922 of the signal wire 92 with other tools or with bare-handed operation, which is inconvenient.

Thus, the conventional crimping pliers can only be applied to the basic type telecommunication connector 9 (as shown in fig. 1A), but cannot be applied to the modified type telecommunication connector 9a (as shown in fig. 1B) or the modified type telecommunication connector 9B (as shown in fig. 1C), and thus, the improvement is necessary.

To better understand the technical content of the present invention, preferred embodiments are specifically illustrated as follows.

Fig. 2A is a schematic view of a crimping tong according to an embodiment of the present invention, fig. 2B is a rear view of the crimping tong shown in fig. 2A, fig. 3 is an exploded schematic view of the crimping tong shown in fig. 2A, fig. 4A is a schematic view of the crimping tong shown in fig. 2A in an open state, and fig. 4B is a schematic view of the crimping tong shown in fig. 2B in an open state, please refer to fig. 1A, fig. 1B, fig. 2A, fig. 2B, fig. 3, fig. 4A and fig. 4B. The crimping pliers 1 of the present embodiment are used for crimping a telecommunications contact 9, 9a, i.e. the crimping pliers 1 can crimp two different types of telecommunications contacts, including a basic type telecommunications contact 9 (as shown in fig. 1A) and a modified type telecommunications contact 9a (as shown in fig. 1B), and the crimping of the basic type telecommunications contact 9 is first described as an example. As described in the background section, the telecommunications connector 9 includes a connection terminal 91 and a signal line 92. The connection terminal 91 includes a plurality of conductive pads 911 and a connection block 912, and the signal line 92 includes a plurality of wire cores 921. The cores 921 are arranged at the front ends of the connection terminals 91 and respectively correspond to the conductive sheets 911. In the present embodiment, the crimping pliers 1 includes a body 10 and a cavity set 20. The body 10 includes a first handle 11, a second handle 12, a first tooth pressing member 13, a pressing member 14 and a functional member 15. The second handle 12 and the first handle 11 are pivotally connected to each other, so that the crimping pliers 1 can be in a closed state (as shown in fig. 2A or fig. 2B) or an open state (as shown in fig. 4A or fig. 4B).

As shown in fig. 2B and fig. 3, the first tooth pressing member 13 is disposed on the first handle 11, and one end of the first tooth pressing member 13 facing the second handle 12 has a tooth-shaped structure for pressing and connecting the conductive sheet 911 and the wire core 921. As shown in fig. 2A and 3, the pressing member 14 is also disposed on the first handle 11, and an end of the pressing member 14 facing the second handle 12 is a planar structure for pressing the connection block 912 and the signal line 92. The first tooth pressing member 13 and the crimping member 14 are located on opposite sides of the first jaw shank 11. In the present embodiment, the first tooth pressing member 13 is located on the side as shown in fig. 2B, and the crimping member 14 is located on the side as shown in fig. 2A. The first tooth pressing member 13 and the pressing member 14 have a gap therebetween, and a line connecting the first tooth pressing member 13 and the pressing member 14 is perpendicular to the long axis direction of the first jaw handle 11.

As shown in fig. 2B and fig. 3, the functional component 15 of the present embodiment is also disposed on the first caliper handle 11 and adjacent to the first tooth pressing member 13. Since the crimping member 14 corresponds to the first ratchet 13, the functional component 15 is also disposed adjacent to the first ratchet 13. For example, the first tooth pressing member 13 (or the pressing member 14) and the functional member 15 are arranged in this order from the front end of the first caliper handle 11 to the rear. The functional component 15 of the present embodiment is a blade, and is referred to as a first blade herein. The functional component 15 (first blade) is used to cut the wire core 921 of the modified telecommunications connector 9a, as will be described further below.

In the present embodiment, the mold cavity 20 is disposed between the first and second handles 11 and 12. Specifically, the mold cavity set 20 has an upper portion 21 and a lower portion 22. The upper portion 21 is connected to the first jaw shank 11 and the lower portion 22 is connected to the second jaw shank 12. In this embodiment, the mold cavity assembly 20 includes a first mold cavity 23 and a second mold cavity 24. The first mold cavity 23 and the second mold cavity 24 are located in the lower portion 22, so that the first mold cavity 23 and the second mold cavity 24 are located in the second plier handle 12. When the cavity set 20 is assembled to the body 10, the first tooth pressing member 13, the pressing member 14 and the functional component 15 are all accommodated in the cavity set 20. Wherein the first cavity 23 corresponds to the first tooth pressing member 13 and the pressing member 14, and the second cavity 24 corresponds to the functional component 15. Specifically, the first mold cavity 23 and the second mold cavity 24 of the present embodiment are arranged transversely to the second forceps handle 12. That is, the long axis directions of the first mold cavity 23 and the second mold cavity 24 are perpendicular to the long axis direction of the second clamp handle 12, and two opposite ends of the first mold cavity 23 can correspond to the first tooth pressing member 13 and the pressing member 14, respectively.

In this embodiment, the cavity assembly 20 further includes a slot 25 (as shown in fig. 3) in the upper portion 21, the lower portion 22 is fixed to the second handle 12, and a portion of the first handle 11 is movable in the slot 25. In addition, the mold cavity set 20 further includes a first guiding groove 26, a second guiding groove 27 and a third guiding groove 28 on the upper portion 21. The first and second guide grooves 26 and 27 are located on opposite sides of the slot 25 to receive the first tooth pressing member 13 and the pressing member 14, respectively. Specifically, the first tooth presser 13 is accommodated in the first guide groove 26, and the crimp member 14 is accommodated in the second guide groove 27. Also, the third guide groove 28 is adjacent to the first guide groove 26, so that the functional component 15 can be accommodated in the third guide groove 28.

The first handle 11 is movable relative to the second handle 12 to cause the crimping pliers 1 to assume an open state (as shown in fig. 4A and 4B) or a closed state (as shown in fig. 2A and 2B). When the first handle 11 moves relative to the second handle 12, the first handle 11 can move in the slot 25, and the first tooth pressing member 13 and the pressing member 14 move in the first guiding groove 26 and the second guiding groove 27 respectively toward the first cavity 23, so that the functional component 15 moves in the third guiding groove 28 toward the second cavity 24. In other words, when the first and second handles 11 and 12 are close to each other, the first tooth pressing member 13 and the pressing member 14 enter the first cavity 23, and the functional component 15 enters the second cavity 24.

When the basic type telecommunications connector 9 is crimped, the distributor can place the connection terminal 91 in the first cavity 23 and make the conductive sheet 911 correspond to the first tine 13. Next, the distributor applies a force to the first and second handles 11 and 12 to move the first handle 11 relative to the second handle 12. When the first and second jaws 11 and 12 approach each other, the first tooth pressing member 13 presses the conductive sheet 911 against the wire core 921, and the pressing member 14 presses the connection block 912 of the connection terminal 91 down to fit into the housing 922 of the signal line 92, thereby fixing the connection terminal 91 and the signal line 92.

As mentioned above, the functional component 15 of the present embodiment is the (first) blade, so the crimping pliers 1 of the present embodiment can also be used for crimping the improved telecommunication connector 9 a. The telecommunications connector 9a has a through connection terminal 91a (shown in fig. 1B). As described in the background section, the connection terminal 91a has an opening 913a at the front end. For convenience of operation, the distributor may first pull out the wire core 921 from the through connection terminal 91a, so that the wire core 921 is arranged at the front end of the connection terminal 91a and protrudes from the connection terminal 91 a.

When the improved telecommunication connector 9a is pressed, the distributor can first place the through connection terminal 91a into the first cavity 23 to press the conductive sheet 911 and the wire core 921 and fix the connection terminal 91 and the signal wire 92 through the connection block 912. Then, the connection terminal 91a is placed in the second cavity 24. At this time, the functional component 15 (first blade) is located outside the connection terminal 91 a. When the first and second forceps handles 11 and 12 are close to each other, the functional part 15 (first blade) can cut the core 921 protruding from the connection terminal 91 a. In other embodiments, the connection terminal 91a may be placed in the second cavity 24, the cutting of the core 921 is completed, and then the connection terminal 91a is placed in the first cavity 23, so as to complete the pressing process. In other words, the present invention does not limit the order of crimping and cutting.

As shown in fig. 2A and 4A, preferably, the body 10 of the present embodiment further includes a limit screw 18 disposed on the first clamp handle 11. As shown in fig. 2B and 4B, the limiting screw 18 is inserted through the first handle 11 and passes through the rear portion of the first handle 11 to contact the second handle 12. Correspondingly, the second handle 12 has a limiting portion 122 near one side of the limiting screw 18. When the first handle 11 and the second handle 12 are away from each other, that is, when the pressing pliers 1 changes from the closed state to the open state, the limiting screw 18 gradually approaches the limiting portion 122 until the limiting portion 122 abuts against the limiting screw 18. At this time, the crimping pliers 1 is in an open state, and abuts against the limit screw 18 through the limit portion 122 to limit the included angle between the first plier handle 11 and the second plier handle 12. In other words, the limiting screw 18 and the limiting portion 122 can limit the opening degree of the crimping pliers 1 in the open state and can serve as a stop point in the open state. Therefore, the risk of the tooth pressing member 13, the pressure contact member 14, and the functional member 15 falling off due to the excessive opening of the first and second handles 11 and 12 can be avoided. Specifically, when the first and second handles 11 and 12 are opened excessively, the first tooth pressing member 13, the pressure welding member 14, and the functional member 15 may fall out of the first, second, and third guide grooves 26, 27, and 28. Therefore, the opening degree of the crimping tong 1 in the open state is limited, and the aforementioned falling-off can be avoided, so that the first tooth pressing member 13, the crimping member 14, and the functional member 15 can be ensured to move in the first guide groove 26, the second guide groove 27, and the third guide groove 28, without using other fixing structures, and the effect of simplifying the components of the crimping tong 1 can be achieved.

In this embodiment, the first tooth pressing member 13, the pressing member 14 and the functional component 15 can be mounted on the first handle 11, and then the limiting screw 18 can be locked to the first handle 11 and the second handle 12. Since the opening degree of the first and second handles 11 and 12 is not limited when the limit screw 18 is not locked, the first and second handles can be opened to a degree that facilitates the installation of the first tooth pressing member 13, the pressing member 14, and the functional member 15. After the first tooth pressing member 13, the pressing member 14, and the functional component 15 are mounted on the first clamp handle 11, the first clamp handle 11 is close to the second clamp handle 12, and the first clamp handle 11 is inserted into the insertion slot 25 of the cavity set 20. At this time, the first tooth pressing member 13, the pressing member 14 and the functional component 15 are driven by the first forceps handle 11 to be placed in the first guiding groove 26, the second guiding groove 27 and the third guiding groove 28, and the first guiding groove 26, the second guiding groove 27 and the third guiding groove 28 can provide a vertical limiting function. Finally, the limiting screw 18 is locked into the first handle 11 and the second handle 12 to limit the opening degree of the first handle 11 and the second handle 12, and the first tooth pressing member 13, the pressing member 14 and the functional component 15 can be prevented from falling off due to the limiting effect. Therefore, the design of the limit screw 18 contributes to the efficiency of assembling the crimping pliers 1 in addition to preventing the parts from falling off.

Fig. 5A is a schematic view of a crimping tong according to another embodiment of the present invention, fig. 5B is a rear view of the crimping tong shown in fig. 5A, fig. 6 is an exploded schematic view of the crimping tong shown in fig. 5A, and fig. 7 is a schematic view of the crimping tong shown in fig. 5A in an open state, please refer to fig. 1A, fig. 1C, fig. 5A, fig. 5B and fig. 6. The difference between the present embodiment of the pliers 1a and the pliers 1 of the previous embodiment is that the functional component 15a and the body 10a of the present embodiment further include a clamp set 16 a. Other elements and their connections are the same as those in the previous embodiments, and thus, the descriptions thereof are omitted and their reference numerals are used. As shown in fig. 5B and fig. 6, the functional component 15a of the present embodiment is a tooth pressing member, and is referred to as a second tooth pressing member herein. Specifically, the pressure contact pliers 1a of the present embodiment includes two pressure teeth, i.e., a first pressure tooth 13 and a functional member 15a (second pressure tooth). Similarly, the functional member 15a (second tooth presser) is provided on the first jaw lever 11 adjacent to the first tooth presser 13. Also, the functional component 15a (second tooth pressing member) is accommodated in the third guide groove 28 so as to correspond to the second cavity 24.

The crimping pliers 1A of the present embodiment may be used to crimp a modified telecommunications contact 9B (shown in fig. 1B) in addition to a basic telecommunications contact 9 (shown in fig. 1A). When the basic type telecommunication connector 9 is to be pressed, the connection terminal 91 of the telecommunication connector 9 is first placed in the first cavity 23, and then the first clamp handle 11 and the second clamp handle 12 are applied with force. For the actuation of the first tooth pressing member 13 and the pressing member 14, reference is made to the foregoing embodiments, which are not repeated herein. When the improved electrical connector 9b is to be pressed, the connection terminal 91b of the electrical connector 9b is inserted into the second cavity 24, and the functional component 15a (second pressing tooth element) is corresponding to the conductive sheet 911 of the electrical connector 9 b.

Specifically, the modified telecommunications connector 9b includes a connection terminal 91b, a signal line 92, and a metal shell 93b, and the metal shell 93 is disposed outside the connection terminal 91 b. The connection terminal 91b does not have the connection block 912, and the metal shell 93 is close to the rear end of the connection terminal 91 b. If the connection terminal 91b is placed in the first cavity 23, the crimp 14 is blocked by the metal shell 93b and thus cannot be crimped. Therefore, the connection terminal 91b of the modified electrical connector 9b must be inserted into the second cavity 24. Similarly, the connection terminal 91b is first placed in the second cavity 24, and then the first or second clamp handle 11, 12 is pressed. When the first and second clamp handles 11 and 12 are forced to approach each other, the functional component 15a (second tooth pressing member) enters the second cavity 24 and presses the conductive piece 911 to the wire core 921.

The metal shell 93b has two extending portions 931b and is located outside the signal line 92. After the conductive plate 911 is pressed, the telecommunications connector 9b is moved to the position of the clamp set 16a, and the extension 931b of the metal shell 93b surrounds the housing 922 of the signal wire 92 through the clamp set 16a, as shown in fig. 1C. In the present embodiment, the clamp set 16a includes a first recess 161a and a second recess 162a, the first recess 161a is disposed on the first handle 11, and the second recess 162a is disposed on the second handle 12. The distributor can place the signal line 92 together with the extension 931b of the metal shell 93b in the jig set 16a, and the extension 931b is placed in the first recess 161a or the second recess 162 a. Then, the first and second handles 11, 12 are urged to move the first and second handles 11, 12 closer to each other. At this time, the first recess 161a and the second recess 162a are closed to form a ring structure, and the extension 931b is bent to wind around the housing 922 of the signal line 92, so as to form the telecommunication connector 9b shown in fig. 1C, thereby fixing the connection terminal 91b and the signal line 92.

In addition, the distributor must first peel off the housing 922 of the signal line 92 to expose the core 921 enclosed in the housing 922. The crimping pliers 1 and the crimping pliers 1a of the embodiment of the present invention both include a wire stripping structure, and the following description takes the crimping pliers 1 as an example. Specifically, the body 10 further includes a second blade 17, which is a groove structure and is disposed on the first handle 11. Correspondingly, the cavity set 20 further includes a receiving groove 29 at the lower portion 22, so that the second blade 17 corresponds to the receiving groove 29.

When the distributor needs to peel off the housing 922 of the signal line 92, the signal line 92 can be placed in the receiving slot 29. Subsequently, the first and second handles 11, 12 are urged to move the first and second handles 11, 12 closer to each other. At this time, the second blade 17 abuts (or pierces) the housing 922 of the signal wire 92. The distributor may rotate the signal wires 92 to make the housing 922 to be scored to cut and peel the housing 922.

As shown in fig. 3 and 4, the second forceps handle 12 further includes a wire-cutting portion 121, which is a planar structure corresponding to the second blade 17 and is disposed adjacent to the receiving groove 29. In other words, the second blade 17 corresponds to the receiving groove 29 and the trimming portion 121. When the distributor needs to cut the signal line 92, the signal line 92 may be placed at the cut-off portion 121. When the first and second handles 11 and 12 are close to each other, the signal wire 92 can be cut by the second blade 17.

In summary, the crimping pliers according to the present invention includes a body and a cavity set. The body includes first pincers handle, second pincers handle, first pressure tooth spare, crimping spare and functional unit, and first pressure tooth spare, crimping spare and functional unit set up in first pincers handle. The mold cavity set comprises a first mold cavity and a second mold cavity. The first cavity corresponds to the first tooth pressing member and the press-contact member, and the second cavity corresponds to the functional part. When the first clamp handle and the second clamp handle are close to each other, the first tooth pressing piece and the pressing piece can enter the first die cavity, and the functional component can enter the second die cavity, so that the connector can be applied to basic and improved telecommunication connectors. Specifically, the basic type telecommunication connector can be placed in the first cavity, the conductive sheet is pressed to the wire core through the first tooth pressing member, and the pressing member fixes the connecting terminal and the signal wire. If the improved telecommunication connector has a through connection terminal, it can be placed in the second cavity and the signal line protruding from the connection terminal is cut by the functional component of the (first) blade. If the improved telecommunication connector has a metal shell, it can be placed in the second cavity and the conductive sheet is pressed to the wire core by the functional part of the (second) pressing tooth part.

It should be noted that the above-mentioned embodiments are merely examples for convenience of description, and the scope of the claims of the present invention should be determined by the appended claims rather than by the foregoing examples.
