Description

Crimping pliers

This creation is about a pressure clamp.

With the development of communication technology, almost every household has installed a network. Currently, Internet access in a fixed area (such as a home environment or a company) is still mainly wired. This means that the signal must be transmitted through the network cable laid by the telecommunications company. In addition, the network cable needs to be electrically connected to the electronic device through a telecommunication connector (or network terminal).

Figure 1 is a schematic diagram of a common telecommunication connector, please refer to Figure 1. Generally speaking, the telecommunication connector 9 includes a connecting terminal 91 and a signal line 92. The common connecting terminal 91 is a plastic shell, and the front end of the connecting terminal 91 has a plurality of conductive sheets 911 (or gold sheets). The signal line 92 is wound by a plurality of cores 921, and the outer layer is covered with a non-conductive shell 922. The wiring personnel must arrange the multiple cores 921 of the signal line 92 at the front end of the connection terminal 91 to correspond to the conductive sheets 911 of the connection terminal 91 respectively. The conventional crimping tool has a terminal accommodating part and a toothed pressing block, so that the wiring personnel can place the connecting terminal 91 in the terminal accommodating part and crimp the conductive sheet 911 and the wire core 921 through the toothed pressing plate.

Fig. 5 is a partial schematic diagram of the telecommunications connector 9a shown in Fig. 2A applied to the crimping pliers 1 shown in Fig. 3A, Fig. 6 is a schematic diagram of the telecommunications connector 9a shown in Fig. 5 placed in the clamp set 50, and Fig. 7 is Fig. 1 The shown telecommunications connector 9 is applied to the partial schematic diagram of the crimping pliers 1 shown in FIG. 3A, please refer to FIG. 5, FIG. 6 and FIG. 7. The crimping element 40 of this embodiment can be positioned in a first position (as shown in FIG. 5) or a second position (as shown in FIG. 7), so that the first pliers handle 10 and the second pliers handle 20 are close to each other When (that is, when the crimping pliers 1 is in the closed state), the flat end 41 of the crimping member 40 can selectively enter the terminal accommodating portion 11. For example, when the crimping member 40 is positioned at the first position (as shown in FIGS. 5 and 6), and the first pliers handle 10 and the second pliers handle 20 are close to each other, the flat end 41 of the crimping member 40 is located in the terminal container. The outside of the placement portion 11. When the crimping element 40 is positioned at the second position (as shown in FIG. 7), and the first pliers handle 10 and the second pliers handle 20 are close to each other, the flat end 41 of the crimping element 40 can enter the terminal accommodating portion 11 . Therefore, the crimping tool 1 is not only applicable to the telecommunication connector 9a with a metal shell 93, but also applicable to the telecommunication connector 9 with a pure plastic shell.

Specifically, as shown in FIG. 4, the second pliers handle 20 of this embodiment has a positioning post 23 located on the second side plate 22. The crimping member 40 has a first positioning hole 42 and a second positioning hole 43, and the first positioning hole 42 is close to the terminal receiving portion 11. Taking FIG. 4 as an example, the second positioning hole 43 is located above, and the first positioning hole 42 is located below, which is closer to the terminal accommodating portion 11. Therefore, when the positioning post 23 passes through the first positioning hole 42, the crimping member 40 is positioned at the first position (as shown in FIGS. 3A, 5 and 6). This embodiment does not specifically limit the position of the first positioning hole 42, or the length of the crimping member 40, it only needs to be when the crimping pliers 1 is in the closed state (that is, the first pliers handle 10 and the second pliers handle 20 are close to each other) , The flat end 41 of the crimping element 40 is located outside the terminal accommodating portion 11. In other words, when the crimping element 40 is positioned at the first position and the crimping pliers 1 is in the closed state, the flat end 41 of the crimping element 40 will not enter the terminal accommodating portion 11. Therefore, when the crimping element 40 is positioned at the first position, the crimping pliers 1 of this embodiment can be applied to the telecommunication connector 9a with the metal shell 93.

Moreover, when the positioning post 23 passes through the second positioning hole 43, the crimping member 40 is positioned at the second position (as shown in FIG. 7). Since the second positioning hole 43 is located above, when the second positioning hole 43 is fixed to the positioning post 23, the length below the crimping member 40 is longer. Therefore, when the crimping pliers 1 is in the closed state (that is, the first pliers handle 10 and the second pliers handle 20 are close to each other), the flat end 41 of the crimping element 40 can enter the terminal accommodating portion 11, thereby making the crimping pliers 1 It can also be applied to a telecommunication connector 9 with a simple plastic shell and a connecting block 912. The second pliers handle 20 of this embodiment further has a fixing portion 24, which can be, for example, but not limited to, a screw. The fixing part 24 can pass through the first positioning hole 42 or the second positioning hole 43 to be connected to the positioning post 23, and the crimping member 40 is fixed at the first position or the second position by the connection relationship between the positioning post 23 and the fixing part 24 position. It should be noted that the fixing portion 24 shown in FIGS. 3A, 5 and 6 passes through the second positioning hole 43, so the second positioning hole 43 is not marked; and the fixing portion 24 shown in FIG. 7 passes through the first positioning hole 43 Therefore, the first positioning hole 42 is not marked.

First take the crimping of the telecommunication connector 9a as an example for further description, please refer to FIG. 3A, FIG. 3B, FIG. 4, FIG. 5, and FIG. The wiring personnel can first position the crimping member 40 to the first position, for example, the fixing part 24 can be removed, and the positioning post 23 can pass through the first positioning hole 42 located below, and then the fixing part 24 can be locked back. At this time, the length of the crimping element 40 below the fixing portion 24 is relatively short. Next, the connecting terminal 91 of the telecommunication connector 9a is placed in the terminal accommodating portion 11, as shown in FIG. Then, force is applied to the first pliers handle 10 and the second pliers handle 20 to bring the first pliers handle 10 and the second pliers handle 20 close to each other. At this time, the tooth structure 31 of the crimping member 30 enters the terminal accommodating portion 11 and crimps the conductive sheet 911 to the wire core 921. It should be noted that since the crimping element 40 is positioned to the first position, at this time, the flat end 41 of the crimping element 40 is located outside the terminal accommodating portion 11.

After the conductive sheet 911 is crimped, the telecommunication connector 9a is moved to the position of the clamp set 50. As shown in FIG. 6, the extension 931 of the metal shell 93 is surrounded by the outer shell 922 of the signal line 92 by the clamp set 50 (completed Then as shown in Figure 2B). In this embodiment, the clamp set 50 includes a first recess 51 and a second recess 52. The first recess 51 is disposed on the first pliers handle 10, and the second recess 52 is disposed on the second pliers handle 20. The wiring personnel place the signal line 92 together with the extension 931 of the metal shell 93 in the clamp set 50, and the extension 931 is placed in the first recess 51 or the second recess 52. Then, force is applied to the first pliers handle 10 and the second pliers handle 20 to make the first pliers handle 10 and the second pliers handle 20 close to each other. At this time, the first recess 51 and the second recess 52 are closed to form a ring structure together. Therefore, the upper second concave portion 52 can bend the extension portion 931 and wrap the extension portion 931 around the housing 922 of the signal line 92 to form a telecommunication connector 9a as shown in FIG. 2B, thereby fixing the connection terminal 91 and the signal line 92.

Taking the crimping telecommunication connector 9 as an example for further description, please refer to FIG. 3A, FIG. 3B, FIG. 4, and FIG. First, the connection terminal 91 of the telecommunication connector 9 is a plastic part, and has a connection block 912 without a metal shell 93. When applied to this type of telecommunication connector 9, the wiring personnel can first confirm that the crimping piece 40 has been positioned at the second position. As mentioned above, the fixing part 24 can be removed first, and the positioning post 23 can pass through the second positioning hole 43 located above, and then the fixing part 24 can be locked back. At this time, the length of the crimping member 40 below the fixing portion 24 is relatively long.

Similarly, the connecting terminal 91 of the telecommunication connector 9 is placed in the terminal accommodating portion 11, the conductive sheet 911 corresponds to the tooth structure 31 of the crimping member 30, and the connecting block 912 corresponds to the flat end 41 of the crimping member 40 . Then, force is applied to the first pliers handle 10 and the second pliers handle 20 to bring the first pliers handle 10 and the second pliers handle 20 close to each other. At this time, the tooth structure 31 of the crimping member 30 enters the terminal accommodating portion 11 to crimp the conductive sheet 911 to the wire core 921. In addition, the flat end 41 of the crimping element 40 enters the terminal accommodating portion 11, and the connecting block 912 of the connecting terminal 91 is pressed down and embedded in the housing 922 of the signal line 92 to fix the connecting terminal 91 and the signal line 92.

FIG. 8A is a schematic diagram of the crimping pliers shown in FIG. 3A applied to a penetrating connection terminal 91, and FIG. 8B is a schematic diagram of the crimping pliers shown in FIG. 3A being applied to a non-penetrating connection terminal 91b. The connecting terminal 91 can be further divided into two types: penetrating type and non-penetrating type.

The non-penetrating connection terminal 91b (as shown in FIG. 8B) is a type with a closed front end without an opening.

Due to the small size of the core 921 of the signal line 92, it is difficult for the wiring personnel to arrange and align the multiple cores 921 of the signal line 92 to the front end of the connection terminal 91. In order to facilitate operation, most of the wiring personnel will pull the core 921 out of the outside of the penetrating connection terminal 91, as shown in FIG. 1. Then, another cutter is used to trim the core 921 protruding from the connection terminal 91. The crimping pliers 1 of this embodiment further includes a first blade 60 arranged on the outside of the crimping member 30, as shown in FIGS. 3B and 4. The first blade 60 is arranged on the outer side of the pressing gear 30 in a screw lock manner. When the cores 921 are aligned with the front end of the connecting terminal 91, the first blade 60 can also be removed. When the first pliers handle 10 and the second pliers handle 20 are close to each other, the first blade 60 can enter the terminal accommodating portion 11 together with the crimping member 30 to cut the core 921 protruding from the connecting terminal 91.

The first blade 60 of this embodiment is detachable, so as to be applied to the penetrating connection terminal 91 and the non-penetrating connection terminal 91b, respectively. In addition, the crimping pliers 1 further includes a stopper 61. The stopper 61 is disposed on the first side plate 21 and corresponds to the first blade 60. The stopper 61 of this embodiment can be positioned at the third position (as shown in FIG. 8A) and the fourth position (as shown in FIG. 8B). As shown in FIG. 8A, when the penetrating connection terminal 91 is crimped, the first blade 60 is disposed on the outside of the crimping member 30, and the stopper 61 is positioned at the third position. At this time, the stopper 61 retreats to the right (from the perspective of FIG. 8A and FIG. 8B ), and abuts against the outside of the connection terminal 91 through the first blade 60. As shown in FIG. 8B, when the non-penetrating connection terminal 91b is crimped, since the core 921 is located in the connection terminal 91b, there is no need to cut the core 921. At this time, the first blade 60 is removed, and the stopper 61 moves to the left and is positioned at the fourth position to abut the outside of the connection terminal 91b.

Please refer to FIG. 1, FIG. 2A or FIG. 2B together. In addition, the wiring personnel must first peel off the outer shell 922 of the signal line 92 to expose the core 921 covered in the outer shell 922.

Furthermore, the second pliers handle 20 further includes a second blade 25 which is disposed on the second side plate 22 of the second pliers handle 20. In addition, the second blade 25 is located between the crimping member 40 and the second concave portion 52 to correspond to the receiving groove 121 and the thread cutting portion 122 of the wire receiving member 12.

When the wiring personnel need to peel off the outer shell 922 of the signal line 92, the signal line 92 can be placed in the receiving groove 121. Then, force is applied to the first pliers handle 10 and the second pliers handle 20 to bring the first pliers handle 10 and the second pliers handle 20 close to each other. At this time, the second blade 25 abuts (or penetrates) the housing 922 of the signal line 92. The wiring personnel can rotate the signal wire 92 to make a circle of cut marks on the housing 922 to cut and peel off the housing 922.

When the wiring personnel need to cut the signal wire 92, the signal wire 92 can be placed in the wire cutting part 122. The thread cutting part 122 is arranged adjacent to the accommodating groove 121, and the thread cutting part 122 is a plane higher than the accommodating groove 121. When the first pliers handle 10 and the second pliers handle 20 are close to each other, the second blade 25 can cut the signal line 92.

That is, the engaging portion 71 with a larger outer diameter is inserted through the first guide hole 13 to fix the relative position of the first pliers handle 10 and the second pliers handle 20. For example, when the crimping pliers 1 is in the closed state, the locking member 70 can be pushed to the right (that is, in the direction of the first guide hole 13), so that the engaging portion 71 enters the first guide hole 13 to limit the first guide hole 13 The action between the first pliers handle 10 and the second pliers handle 20 further fixes the crimping pliers 1 in the closed state to achieve the effect of safety.

Conversely, when the shaft portion 72 with a smaller outer diameter is located in the first guide hole 13 (as shown in FIG. 9A), the relative position of the first pliers handle 10 and the second pliers handle 20 can be changed. For example, when the crimping pliers 1 is to be used, the locking member 70 can be pushed to the left (that is, pushed in the direction of the second side plate 22), so that the shaft 72 enters the first guide hole 13. Since the outer diameter of the shaft 72 is small, it can move in the first guide hole 13 so that the first pliers handle 10 can be opened and closed relative to the second pliers handle 20, that is, the user can operate the crimping pliers 1.

In summary, the crimping tool according to this creation includes a first pliers handle, a second pliers handle, a crimping piece, a crimping piece, and a clamp set. The first clamp handle has a terminal accommodating part for accommodating the connection terminal of the telecommunication connector. The crimping part and the crimping part are arranged on two opposite surfaces of the second pliers handle and correspond to the terminal accommodating part. In addition, the crimping element can be positioned at the first position or the second position, so that when the first pliers handle and the second pliers handle are close to each other, the flat end of the crimping element can selectively enter the terminal accommodating portion, which is applicable Different types of telecommunications connectors.
