[0002] At present, the connecting wire mainly includes an inner core and an outer insulating layer, wherein the inner core is used to transmit signals, and the outer insulating layer is used to protect the inner core.

[0003] In actual use, when the connecting wire needs to be connected to the terminal, the outer insulation layer at the end of the connecting wire needs to be stripped off to expose the inner core, and then the inner core can be connected to the terminal.

[0004] The current method of stripping the outer insulation layer is usually to cut the outer insulation layer with a knife, and then pull the cut outer insulation layer out of the inner core to complete the stripping operation. This stripping operation has the following shortcomings:

[0005] During the stripping process, the depth of the knife is manually controlled, resulting in inconsistent cutting depths at various locations during the circular cutting process. As a result, the outer insulation layer is cut off at some locations but not at others. At this time, a secondary cutting is required at the locations where the cutting is shallower, which reduces the stripping efficiency. Utility Model Content

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] See also Figure 1-3 , the utility model provides a technical solution:

[0042] A wire stripping device is used to strip the outer sheath of a cable 1, comprising a static tube 2, a centering component 3, a dynamic tube 4 and a lower knife component 5; wherein the static tube 2 and the dynamic tube 4 can be made of hard plastic or metal material, and the purpose is to maintain the shape of the static tube 2 and the dynamic tube 4 during operation and prevent the static tube 2 and the dynamic tube 4 from deformation.

[0043] like Figure 1-Figure 3 As shown, the static tube 2 is sleeved outside the cable 1, and the cable 1 can be coaxially fixed with the static tube 2 through a centering component 3; the dynamic tube 4 is coaxial with the static tube 2 and rotatably connected; in this embodiment, the dynamic tube 4 is rotatably connected with the static tube 2 through a bearing.

[0044] like Figure 1 and Figure 3 As shown, the lower blade assembly 5 includes a fixed tube 51 , a blade 53 and a bolt 55 ; the fixed tube 51 can be made of the same material as the moving tube 4 .

[0045] like Figure 1-Figure 3 As shown, the fixed tube 51 penetrates the tube wall of the moving tube 4 and is fixedly connected to the moving tube 4 , and the axial direction of the fixed tube 51 is perpendicular to the axial direction of the moving tube 4 .

[0046] The blade 53 has a V-shaped edge; when in use, the tip of the V-shaped edge of the blade 53 is inserted into the outer skin (ie, the outer insulating layer) of the cable 1 .

[0047] By turning the bolt 55 , the position of the blade 53 can be driven to be adjusted in the axial direction of the fixing tube 51 , that is, the depth of the tip of the blade 53 penetrating into the outer skin of the cable 1 can be adjusted.

[0048] When in use, first insert one end of the cable 1 from the end of the static tube 2 away from the moving tube 4 into the interior of the static tube 2, and continue to insert until one end of the cable 1 extends out from the end of the moving tube 4 away from the static tube 2, and then use the centering component 3 to adjust the position of the cable 1 inside the static tube 2 and the moving tube 4, so that the cable 1 is coaxial with the static tube 2; then turn the bolt 55 to drive the blade 53 to gradually move toward the cable 1 until the tip of the V-shaped blade edge of the blade 53 pierces the outer skin of the cable 1, and the tip is about to or just pierces the outer skin, and then hold the static tube 2 with one hand and the moving tube 4 with the other hand, keep the static tube 2 still and rotate the moving tube 4, and use the blade 53 to perform circumcision on the outer skin of the cable 1. In this way, the cutting depth of the blade 53 on the outer skin of the cable 1 can be kept consistent. It only needs to adjust the depth of the blade 53 inserted into the outer skin of the cable 1 to cut off the outer skin of the cable 1 at one time, thereby improving the stripping efficiency.

[0049] like Figure 1-Figure 3 As shown, the lower knife assembly 5 also includes a slide rod 52 and a slider 54; specifically, the slide rod 52 is coaxial with the fixed tube 51, and the slide rod 52 and the fixed tube 51 cooperate to form a telescopic rod structure, the bottom end of the slide rod 52 is fixedly connected to the blade 53, and the top end of the slide rod 52 is fixedly connected to the slider 54, and the slider 54 is axially slidably connected to the inside of the fixed tube 51; a limiting ring is fixed at the bottom end of the fixed tube 51, and its inner diameter is smaller than the outer diameter of the slider 54, so that the position of the slider 54 can be limited to prevent the slider 54 from sliding out of the fixed tube 51.

[0050] like Figure 1-Figure 3As shown, a strip groove 511 is formed on the side wall of the fixed tube 51 , and the length direction of the strip groove 511 is parallel to the axial direction of the fixed tube 51 ; a protrusion 541 is fixed on the side of the slider 54 ; the protrusion 541 is slidably connected to the strip groove 511 .

[0051] The strip groove 511 and the protrusion 541 are provided to limit the sliding direction of the slider 54 , so that the slider 54 can only slide in the axial direction of the fixed tube 51 and cannot rotate inside the fixed tube 51 .

[0052] like Figure 1-Figure 3 As shown, the centering assembly 3 includes a bidirectional screw 31, a connecting seat 32, two arc plates 36 and two nuts 38; the axial midpoint position of the bidirectional screw 31 is rotatably connected to the static tube 2 through the connecting seat 32, and the axial direction of the bidirectional screw 31 is perpendicular to the axial direction of the static tube 2; the two nuts 38 are respectively threadedly connected to the two sections of the thread of the bidirectional screw 31; the two arc plates 36 are respectively fixedly connected to the two nuts 38; the distance between one end of the arc plate 36 and the blade 53 is less than two millimeters.

[0053] Furthermore, the centering assembly 3 also includes two connecting rods 33, two guide rods 34 and two guide sleeves 35; one end of the connecting rod 33 is fixedly connected to the nut 38, the other end of the connecting rod 33 is fixedly connected to one end of the guide rod 34, and the other end of the guide rod 34 is fixedly connected to the arc plate 36; the guide sleeve 35 passes through the wall of the static pipe 2 and is fixedly connected to the static pipe 2, the guide rod 34 slides through the guide sleeve 35, and the axial direction of the guide rod 34 is perpendicular to the axial direction of the static pipe 2.

[0054] In actual use, due to the setting of the connecting seat 32, it can limit the bidirectional screw 31 to rotate only around its own axis and will not move relative to the static tube 2. Therefore, by rotating the bidirectional screw 31, the two nuts 38 gradually move closer to the middle, so that the distance between the two connecting rods 33 and the two guide rods 34 gradually decreases, that is, the two arc plates 36 gradually approach the cable 1 until they are clamped, so that the centering of the cable 1 can be completed and it can be kept coaxial with the static tube 2; further, because the distance between one end of the arc plate 36 and the blade 53 is less than two millimeters, therefore, during the circumferential cutting process, the cable 1 will not bend and deform due to the squeezing force of the blade 53, which is conducive to maintaining the consistency of the cutting depth.

[0055] like Figure 2 As shown, the centering component 3 also includes a gasket 37, which is fixed on the inner arc surface of the arc plate 36; the gasket 37 is made of rubber material, and the gasket 37 can increase the friction force and improve the stability when the two arc plates 36 clamp the cable 1.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
