[0046] Please also see Figures 1 to 3 The embodiment of the present invention provides a wire stripper for stripping the insulation coating to be stripped from the cable to expose the wire core of the cable. The wire stripper 1 comprises an upper clamp body 100, a lower clamp body 200 and a stripping structure 300. The upper clamp body 100 and the lower clamp body 200 are cross-hinged and can slide relative to each other through a cylindrical pin 400. The upper clamp body 100 and the lower clamp body 200 together form a jaw 10 for inserting the cable and opening and closing.

[0047] The stripping structure 300 includes an upper blade 310 and a lower blade 320. Both the upper blade 310 and the lower blade 320 are arranged on the jaws 10. The upper blade 310 is installed on the upper jaw body 100 with its cutting edge facing downward, and the lower blade 320 is arranged on the lower jaw body 200 with its cutting edge facing upward and opposite to the cutting edge of the upper blade 310.

[0048] When the jaws 10 are closed, the upper blade 310 is in a skin cutting state in which it shears the insulation to be stripped together with the lower blade 320. After the skin cutting state, the upper jaw body 100 and the lower jaw body 200 slide relative to each other to drive the upper blade 310 and the lower blade 320 to be relatively displaced to each other in a stripping state in which the insulation to be stripped is stripped off.

[0049] In this embodiment, the upper jaw body 100 and the lower jaw body 200 of the wire stripper 1 are cross-arranged and hinged together by a cylindrical pin 400. The upper jaw body 100 and the lower jaw body 200 together form a jaw 10 for inserting a cable and the two can slide relative to each other in a dislocated manner. Since the upper jaw body 100 and the lower jaw body 200 are cross-hinged by the cylindrical pin 400, that is, the two can rotate relative to each other, thus, the opening and closing (opening and closing) operation of the jaw 10 can be realized. The stripping structure 300 of the wire stripper 1 includes an upper blade 310 and a lower blade 320, both of which are arranged at the jaw 10, the upper blade 310 is installed on the upper jaw body 100 and its cutting edge faces downward, and the lower blade 320 is arranged on the lower jaw body 200 and its cutting edge faces upward and is opposite to the cutting edge of the upper blade 310. When it is necessary to remove the insulation skin at one end of the cable, it is only necessary to operate the upper clamp body 100 and the lower clamp body 200, and the two rotate relative to each other to close the jaw 10. At this time, the upper blade 310 and the lower blade 320 clamp the cable together and cut the insulation skin to be stripped together, which is the skin cutting state; after the skin cutting state, continue to operate the upper clamp body 100 and the lower clamp body 200, so that the upper clamp body 100 and the lower clamp body 200 slide relative to each other, thereby driving the upper blade 310 and the lower blade 320 to be relatively displaced by a certain distance, and the sheared insulation skin to be stripped is torn off due to the dislocation of the two blades, so that the wire core of the section of the cable is exposed, which is the stripping state. The structure is simple, the operation is convenient, and there is no need to apply external force to pull and strip, which saves trouble and labor, and will not cause damage to the wire core due to excessive external force.

[0050] In this embodiment, the cutting edges of the upper blade 310 and the lower blade 320 are both V-shaped, which can strip cables of various sizes. Of course, the cutting edge shape is not limited and can also be U-shaped or arc-shaped, as long as the stripping requirements are met.

[0051] Please also see Figures 1 to 3Furthermore, the upper clamp body 100 includes an upper clamp portion 110, an upper transition portion 120 and an operating portion 130. The upper transition portion 120 connects the upper clamp portion 110 and the operating portion 130. The upper transition portion 120 is provided with an upper transition cavity 101 extending obliquely up and down and a sliding hole 102 that penetrates front and back and is in a strip shape.

[0052] In this embodiment, the sliding hole 102 extends in the left-right direction. The upper clamp portion 110, the upper transition portion 120 and the operating portion 130 are formed in one body.

[0053] The lower jaw body 200 includes a lower jaw portion 210 , a lower transition portion 220 and a support portion 230 . The lower transition portion 220 connects the lower jaw portion 210 and the support portion 230 . The lower transition portion 220 is provided with a connecting hole 201 that passes through from front to back.

[0054] In this embodiment, the lower clamp portion 210, the lower adapter portion 220 and the support portion 230 are formed into one body.

[0055] The lower jaw portion 210 passes through the upper adapter cavity 101 and is located below the upper jaw portion 110, and together with the lower jaw portion 210 forms the jaw 10; the lower adapter portion 220 is inserted into the upper adapter cavity 101, the connecting hole 201 is opposite to the sliding hole 102, the cylindrical pin 400 passes through the sliding hole 102 and the connecting hole 201, the upper blade 310 is installed on the upper jaw portion 110, and the lower blade 320 is installed on the lower jaw portion 210.

[0056] The cylindrical pin 400 abuts against one hole wall of the sliding hole 102 along the length direction in the skin cutting state, and slides along the length direction of the sliding hole 102 and abuts against the other hole wall in the peeling state.

[0057] In this embodiment, the cylindrical pin 400 is tightly matched with the connecting hole 201 of the lower transition part 220 , so that the upper caliper body 100 and the lower caliper body 200 can slide relative to each other.

[0058] See also Figures 1 to 3 Preferably, the wire stripper 1 further comprises a limiting sleeve 500, which is inserted into the connection hole 201 of the lower adapter 220 and matched with the connection hole 201. The outer contour of the cross section of the limiting sleeve 500 is an outer contour that can prevent relative rotation between it and the lower adapter 220. The cylindrical pin 400 is inserted into the inner cavity of the limiting sleeve 500 and has an interference fit with the limiting sleeve 500. In this way, relative rotation between the lower adapter 220 and the limiting sleeve 500 is effectively prevented. The outer contour of the cross section of the limiting sleeve 500 can be elliptical, approximately triangular, etc., or other special shapes.

[0059] Please also see Figure 2 and Figure 3Specifically, at least one limiting groove 501 is provided on the outer wall of the limiting sleeve 500 along the length direction. The lower caliper body 200 further includes at least one limiting block 240 formed by protruding from the hole wall of the connecting hole 201. The limiting sleeve 500 is inserted into the connecting hole 201, and each limiting block 240 is respectively inserted into a limiting groove 501 and slidably cooperates with the limiting groove 501. In this way, on the one hand, the limiting sleeve 500 is positioned and installed by slidingly cooperating with the limiting groove 501; on the other hand, the limiting block 240 is inserted into the limiting groove 501, which can effectively prevent the relative rotation between the lower caliper body 200 and the limiting sleeve 500, thereby realizing circumferential limiting.

[0060] Please also see Figures 2 to 5 Preferably, the wire stripper 1 further comprises a wire crimping structure 600, the lower adapter portion 220 is provided with a lower adapter cavity 202 connected to both the connecting hole 201 and the upper adapter cavity 101, and the upper clamp portion 110 is provided with an upper through cavity 103 connected to the upper adapter cavity 101 along its length direction.

[0061] One end of the wire pressing structure 600 is located in the lower transfer cavity 202 and connected to the limiting sleeve 500, and the other end thereof passes through the upper through cavity 103 and extends out and always clamps the cable together with the lower clamp 210 in the skin cutting state and the stripping state, and the clamped part of the cable is the non-stripping part. The cutting edge of the upper blade 310 is located on the right side of the wire pressing end of the wire pressing structure 600.

[0062] In this embodiment, the end of the cable to be stripped is inserted from left to right into the jaws 10. The end of the cable to be stripped is inserted into the cutting edge and can be directly placed on the lower jaw 210, and the portion of the insulation to be stripped is placed on the cutting edge of the lower blade 320. When the cable is in the skin cutting state, the wire pressing structure 600 will also rotate downward with the upper jaw 110 until the upper blade 310 and the lower blade 320 jointly clamp the cable to be stripped and the insulation to be stripped of the cable. At this time, the wire pressing end of the wire pressing structure 600 and the lower jaw 210 jointly clamp the cable, effectively preventing the cable from rotating or shifting, which affects the stripping effect of the insulation.

[0064] In this embodiment, the limiting sleeve 500 is passed through the adapter hole 601 of the main board body 621 and fits tightly with the adapter hole 601 to prevent the rotating plate 620 from shaking. In addition, the cable cutting structure introduced next cannot provide sufficient extrusion force, and thus cable cutting cannot be achieved.

[0065] In this embodiment, the end surface of the pressing foot 612 is provided with a V-shaped groove (not marked in the figure), so that, on the one hand, it prevents the cable from moving back and forth; on the other hand, it satisfies the pressing requirements of cables of various sizes.
