Description

Technical Field

[0001] This utility model relates to a network cable ring cutter and stripper, belonging to the field of network cable stripping technology. Background Technology

[0002] Network cables generally consist of an outermost insulating layer and two or four sets of twisted pairs. Each twisted pair comprises two insulated core wires twisted together at a specific density. The use of a network cable typically involves three steps: first, stripping a certain length of the outer insulation layer; second, unwinding and straightening the twisted core wires; and finally, pressing the straightened core wires into the terminals to be installed. Currently, network cable tools have the following shortcomings in their use:

[0003] 1. The wire stripping tools used by professionals in the stripping process are complex in structure, have high production costs, are inconvenient to use, and are not efficient. For example, Chinese invention patent application publication number CN111326992A discloses a wire stripping device for electronic information engineering experiments. This wire stripping device requires the blade to contact the insulation layer of the wire through the blade adjustment part and cut into it before performing circumferential stripping, which is quite troublesome to operate.

[0004] 2. Professionals usually need to use three different tools in turn to strip, straighten and snap the wires in these three steps. This is cumbersome, inefficient and the three tools are easy to lose when not in use. Utility Model Content

[0005] The present invention aims to provide a wire stripper for circumferential cutting of network cables, which solves the problems of existing wire stripping tools having complex structures, high production costs, inconvenience in use, and low efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wire stripper for slicing and stripping network cables includes a body with a cutting cavity extending through the middle of the body, a blade on the body near one end of the cutting cavity, and a centrifugal end on the body near the other end of the cutting cavity.

[0008] The blade extends into the cutting cavity and is perpendicular to the through axis of the cutting cavity. The blade and the cutting cavity form a threading channel, and the size of the threading channel is larger than the size of the wire.

[0009] During wire stripping, the network cable is passed through the cable threading channel, bringing it into contact with the blade. The centrifugal end then rotates around the cable, applying pressure to the cable and moving in a circular motion to achieve a circumferential cut. Finally, the wire stripper is removed, and the insulation layer of the circumferentially cut network cable is peeled off by hand. The pressure of the blade on the network cable is adjusted by controlling the centrifugal motion to accommodate different cable stripping requirements. This circumferential wire stripper solves the problems of complex structure, high production cost, inconvenience, and low efficiency of existing wire stripping tools.

[0010] Furthermore, the centrifugal end includes a finger-piercing cavity that penetrates the body of the device, and the penetrating axis of the finger-piercing cavity is parallel to the penetrating axis of the cutting cavity.

[0011] Furthermore, the cutting cavity is connected to the finger-piercing cavity.

[0012] Furthermore, the device body includes a main body section and an extension section, the centrifugal end includes the extension section, the extension section is rotatably connected to the main body section, and the rotation axis of the extension section is parallel to the through axis of the cutting cavity.

[0013] Furthermore, in order to untangle and straighten the intertwined core wires within the network cable, a straight end is provided extending from the device body.

[0014] Furthermore, the straight end includes a post and two auxiliary pressure plates parallel to the length extension direction of the post. The two auxiliary pressure plates are respectively spaced apart from the post and are spaced apart from each other. The side wall of the auxiliary pressure plate facing the post has a concave surface parallel to the length extension axis of the post. One end of the auxiliary pressure plate is fixed to the device body, and the post extends out of the auxiliary pressure plate.

[0015] Furthermore, in order to insert the core wires inside the network cable into the installation module at the end of the network cable, a punch end is provided extending from the device body. The punch end includes a punch blade with a groove at the front end and the rear end is fixed to the device body.

[0016] Furthermore, the blade includes at least one cutting edge, which extends from the side wall or end of the cutting cavity blade end, and the shape of the cutting edge is one or a combination of straight, oblique, arc, and serrated.

[0017] Furthermore, the distance between the two side walls of the cutting cavity gradually decreases from the blade end closest to the cutting cavity to form a narrowing.

[0018] Furthermore, the device body is provided with at least one set of the cutting cavities and the blade.

[0019] Furthermore, the blade is fixedly mounted on the body of the device, and the cutting cavity therein is fixed to the body of the device.

[0020] Furthermore, a mounting base is connected to the device body via a plug-in connection, and the blade is fixed on the mounting base.

[0021] Furthermore, the device body is provided with an adjustment mechanism for adjusting the cutting edge of the blade to extend into the cutting cavity; the adjustment mechanism includes a handwheel forming a rotating pair with the device body and a blade holder forming a sliding pair with the device body, the handwheel is provided with an axially penetrating threaded hole in the middle, the blade is fixed at one end of the blade holder near the cutting cavity, and a screw extends from the other end of the blade holder, and the handwheel is threadedly connected to the blade holder.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Example 1

[0038] See Figure 1 This embodiment provides a network cable stripper. The network cable stripper includes a body 1, with a cutting cavity 3 penetrating through the middle of the body 1. A blade 2 is provided on one end of the body 1 near the cutting cavity 3, and a centrifugal end 4 is provided on the other end of the body 1 near the cutting cavity 3. The blade 2 extends into the cutting cavity 3 and is perpendicular to the penetrating axis of the cutting cavity 3. The blade 2 and the cutting cavity 3 form a wire threading channel 31, the size of which is larger than the size of the network cable.

[0039] It should be noted that the centrifugal end 4 should be understood as a structure that facilitates centrifugal movement of the wire mesh in this invention. The threading channel 31 is used for the wire mesh to pass through and is positioned at the cutting point. The fact that the threading channel 31 is larger than the wire mesh size should be understood as ensuring that the wire mesh can always pass through during the entire threading and circumferential cutting process, or that the threading channel 31 is always larger than the wire mesh size during the entire stripping process, i.e., always allowing the wire mesh to pass through. The wire mesh consists of an outer insulation layer and two or four sets of wound core wires inside.

[0040] The product's usage process is as follows: When stripping the wire, pass the network cable through the cable threading channel 31. The network cable contacts the blade 2, and the centrifugal end 4 rotates around the network cable. During this centrifugal motion, the blade 2 applies pressure to the network cable and moves around it, achieving a circumferential cut. Finally, remove the wire stripper and peel off the circumferentially cut insulation layer of the network cable by hand. During stripping, the pressure of the blade 2 on the network cable can be adjusted by controlling the centrifugal motion to adapt to the stripping requirements of different network cables.

[0041] In this embodiment, the body 1 is a plate-like structure. The cutting cavity 3 is generally strip-shaped. The blade 2 is integrally fixed to the body 1 or fixed by a snap-fit ​​block, and the blade 2 is straight. In practice, the blade 2 includes at least one cutting edge, which extends from the end or side wall of the cutting cavity 3. The shape of the cutting edge of the blade 2 can be one or a combination of straight, oblique, arc, and serrated; where oblique refers to the blade cutting edge being arranged at an angle.

[0042] In this embodiment, the centrifugal end 4 includes a finger-piercing cavity 41 that penetrates the body 1, and the penetrating axis of the finger-piercing cavity 41 is parallel to the penetrating axis of the cutting cavity 3. A finger passes through the finger-piercing cavity 41 and performs a centrifugal motion around the mesh, thereby causing the blade 2 to exert pressure on the mesh and move around it, achieving a circumferential cut on the mesh. The finger-piercing cavity 41 has a circular hole structure.

[0043] The beneficial effects of this embodiment are as follows: the principle of this utility model is simple, the operation is convenient, the structure is simple, it is easy to produce and expand its functions, and it improves efficiency. During wire stripping, the pressure of the blade 2 on the wire is adjusted by controlling the centrifugal motion to meet the stripping needs of different wires, which has the advantages of flexible use and wide applicability.

[0044] Example 2

[0045] See Figure 2 This embodiment provides another type of network cable stripper. The main difference between this network cable stripper and the first embodiment is that the distance between the two side walls of the cutting cavity 3 gradually decreases from the blade end near the cutting cavity 3 to form a narrowing 5.

[0046] In this embodiment, the two side walls of the constriction 5 are extrusion surfaces 51, which are parallel to the through axis of the cutting cavity 3. The extrusion surfaces 51 are inclined or arc-shaped surfaces.

[0047] The remaining structure and principles of this embodiment are consistent with those of Embodiment 1.

[0048] The beneficial effect of this embodiment is that the wire stripper of this embodiment can increase the pressure of the blade 2 on the wire during centrifugal wire stripping by setting a constriction 5 in the cutting cavity 3, thereby improving the cutting effect.

[0049] Example 3

[0050] See Figure 3 This embodiment provides another type of network cable stripper. The main difference between this network cable stripper and the first embodiment is that the blade 2 has a combination of straight and oblique shapes; the finger cavity 41 is an open hole structure with a rounded arc shape.

[0051] The remaining structure and principles of this embodiment are consistent with those of Embodiment 1.

[0052] The beneficial effect of this embodiment is that the blade 2 of the wire stripper in this embodiment adopts a combination of straight and oblique shapes, which increases the contact between the blade 2 and the wire and improves the cutting effect.

[0053] Example 4

[0054] See Figure 4 This embodiment provides another type of network cable stripper. The main difference between this network cable stripper and the first embodiment is that the blade 2 is fixed on the mounting base 6, and the mounting base 6 is plugged into the body 1.

[0055] In this embodiment, the mounting base 6 is a conventional block structure. Blade 2 is fixed at both ends of the mounting base 6 (i.e., the left and right ends in the figure). By pulling out the mounting base 6 and rotating it 180 degrees, the blade 2 fixed at the other end of the mounting base 6 can be retrieved; alternatively, it can be directly replaced with another mounting base 6 to quickly replace the blade 2.

[0056] In this embodiment, the device body 1 is provided with a mounting groove 61, and the mounting base 6 cooperates with the mounting groove 61 to realize the plug-in connection between the mounting base 6 and the device body 1.

[0057] The remaining structure and principles of this embodiment are consistent with those of Embodiment 1.

[0058] The beneficial effect of this embodiment is that the plug-in connection design between the mounting base 6 and the body 1 enables quick replacement of the blade 2, improving the convenience of blade replacement.

[0059] Example 5

[0060] See Figure 5 This embodiment provides another type of network cable stripper. The main difference between this network cable stripper and the first embodiment is that a straight end 7 extends from the body 1; the straight end 7 is used to loosen and straighten the intertwined core wires in the network cable.

[0061] In this embodiment, a straight end 7 extends from the end of the device body 1 near the blade 2. The straight end 7 includes a post 71 and two auxiliary pressure plates 72 parallel to the length extension direction of the post 71. The two auxiliary pressure plates 72 are spaced apart from the post 71. The auxiliary pressure plates 72 have concave surfaces parallel to the length extension axis of the post 71 on their sidewalls facing the post 71. One end of the auxiliary pressure plate 72 is fixed to the device body 1, and the post 71 extends out of the auxiliary pressure plate 72. Usage: The post 71 is inserted between the wound core wires, and the core wires are placed between the post 71 and the auxiliary pressure plate 72. Then, it moves towards the end of the core wires, and the intertwined core wires are untangled and straightened. The function of the auxiliary pressure plate 72 is to shorten the distance that the end of the wound core wires is stretched, thereby improving the straightening effect.

[0062] In this embodiment, the body 1 is divided into a main body section 11 and an extension section 12, which are arranged in parallel as a whole, with the straight end 7 located at the end of the extension section 12.

[0063] The remaining structure and principles of this embodiment are consistent with those of Embodiment 1.

[0064] The beneficial effects of this embodiment are as follows: the network cable stripper of this embodiment extends the straight end 7 on the body 1, thereby expanding the straight function. It can loosen and straighten the core wire wrapped inside the network cable after stripping, which has the advantages of convenient operation and improved efficiency.

[0065] Example 6

[0066] See Figure 6 This embodiment provides another type of wire stripper. The main difference between this wire stripper and Embodiment 5 is that: the straight end 7 extends parallel to the end of the body 1 away from the blade 2 (i.e., the end close to the centrifugal end 4); the cutting cavity 3 is connected to the finger-penetrating cavity 41; the blade 2 has two oblique blades, and the blade 2 has a strip-shaped mounting groove 8 that is perpendicular to the blade surface and parallel to the extension direction of the body 1.

[0067] In this embodiment, the blade 2 is fixed to the body 1 by screws.

[0068] The remaining structure and principles of this embodiment are the same as those of Embodiment 5.

[0069] The beneficial effect of this embodiment is that the wire stripper of this embodiment can flexibly adjust and fix the length of the blade 2 extending into the cutting cavity 3 through the screw and the strip mounting groove 8 provided on the blade 2, so as to optimize and adapt to different wire stripping needs.

[0070] Example 7

[0071] See Figure 7This embodiment provides another type of network cable stripper. The main difference between this network cable stripper and Embodiment 5 is that the centrifugal end 4 includes an extension section 12, the main body section 11 and the extension section 12 are perpendicular to each other and rotatably connected, and the rotation axis of the extension section 12 is parallel to the through axis of the cutting cavity 3.

[0072] During the wire stripping operation, the network cable is passed through the cable passage 31, and the network cable comes into contact with the blade 2. The extension section 12 is grasped by hand and a centrifugal motion is made around the network cable. During the centrifugal motion, the blade 2 exerts pressure on the network cable and moves around the network cable to achieve the circumferential cutting of the network cable by the blade 2.

[0073] The remaining structure, principle, and effects of this embodiment are consistent with those of Embodiment 5.

[0074] Example 8

[0076] In this embodiment, the body 1 is provided with three blades 2 and three cutting cavities 3.

[0077] The remaining structure and principles of this embodiment are consistent with those of Embodiment 1.

[0078] The beneficial effects of this embodiment are as follows: the network cable stripper of this embodiment expands the wire stripping function by extending the wire stripping end 9 on the body 1, and can insert the core wire inside the network cable into the network cable installation module after stripping, which has the advantages of convenient operation and improved efficiency.

[0079] Example 9

[0080] See Figure 9 This embodiment provides another type of wire stripper for circumferential cutting of network cables. The main difference between this wire stripper and the first embodiment is that an adjustment mechanism 10 for adjusting the blade 2 is added. The adjustment mechanism 10 is used to adjust the length of the blade 2 extending into the cutting cavity 3 before stripping, so as to set the maximum cutting depth of centrifugal circumferential cutting.

[0081] In this embodiment, the adjustment mechanism 10 is axially arranged, or in other words, the adjustment mechanism 10 is arranged along the length of the body 1. The adjustment mechanism 10 includes a handwheel 101 that forms a rotating pair with the body 1 and a blade holder 102 that forms a sliding pair with the body 1. The handwheel 101 has an axially penetrating threaded hole in the middle. The blade 2 is fixed at one end of the blade holder 102 near the cutting cavity 3, and a screw extends from the other end of the blade holder 102. The handwheel 101 is threadedly connected to the blade holder 102. In implementation, a limiting concave ring is provided on the outer side of the handwheel 101. At the same time, two limiting rods 103 are inserted into the body 1 and the limiting concave ring on the outer side of the handwheel 101 in sequence, so that the handwheel 101 can rotate relative to the body 1 but cannot move axially. The screw of the blade holder 102 cooperates with the threaded hole in the handwheel 101. The body 1 has a cavity for the blade holder 102 to slide along the length of the body 1 and a mounting hole for the handwheel 101 to be installed. By turning the handwheel 101, the length of the blade 2 extending into the cutting cavity 3 can be adjusted.

[0082] The remaining structure and principles of this embodiment are consistent with those of Embodiment 1.

[0083] The beneficial effects of this embodiment are as follows: The wire stripper of this embodiment, by setting the adjustment mechanism 10, adjusts the length of the blade 2 extending into the cutting cavity 3 before stripping, so as to adjust the maximum cutting depth, improve the stripping effect, and enhance the applicability to different wires.

The main difference between this network cable stripper and Embodiment Nine is that the adjusting mechanism 10 is perpendicular to the length direction of the body 1 and perpendicular to the through axis of the cutting cavity 3; the blade 2 is oblique in shape.

[0086] The remaining structure and principles of this embodiment are consistent with those of Embodiment Nine.
