Description

Technical Field

[0001] This utility model relates to the field of cable processing, and in particular to a device for stripping the shielded wire mesh layer. Background Technology

[0002] Wire shielding mesh refers to a layer of conductive metal mesh woven around a regular wire. It is usually made of metal materials such as copper, aluminum, or aluminum-magnesium alloy. Its main function is to isolate electromagnetic noise sources from sensitive equipment, cut off the propagation path of noise sources, and ensure the stability and accuracy of high-speed signal transmission in electronic equipment facilities such as computer networks and communication base stations, thereby reducing electromagnetic interference.

[0003] When installing the wires, the shielding mesh needs to be cut to expose the internal copper wires for subsequent installation. To ensure that the shielding mesh does not experience problems such as poor contact or oxidation during long-term use, the cut of the shielding mesh must be flat. Uneven cuts will damage the complete conductive layer of the shielding mesh, causing external electromagnetic interference to seep in through the gaps and reducing the anti-interference ability.

[0004] Cutting wire shielding mesh usually uses sharp scissors or wire strippers. Although the tools are sharp, they cannot peel off the shielding mesh at the same time, and cannot make the cut edge flat. This can easily cause the shielding mesh to become loose and the cut edge to have burrs. Sharp burrs can pierce the insulation layer, and the loose shielding mesh greatly reduces the anti-interference ability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a shielded wire mesh layer stripping device, which aims to improve the problem that the shielded wire mesh layer cannot be quickly and neatly removed in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shielded wire mesh stripping device includes a base plate, a fixing frame fixedly connected to the top of the base plate, a shearing structure installed inside the fixing frame, a support block fixedly connected to the top of the base plate, a fixing block fixedly connected to the outside of the support block, and a stripping tube slidably connected inside the fixing block.

[0008] The shearing structure includes a drive assembly and a telescopic assembly. The telescopic assembly includes a second gear, which is rotatably connected inside the fixed frame. A slide rod is slidably connected to the middle of the second gear, and a telescopic rod is fixedly connected to the outside of the slide rod. A cutter is fixedly connected to the outside of the telescopic rod.

[0009] The drive assembly includes a motor, which is fixedly connected to the top of the base plate. A first gear is fixedly connected to the output end of the motor, and the first gear meshes with a second gear.

[0010] The second gear has a first groove and a second groove in the middle, the slide rod is slidably connected inside the first groove, and the cutter is slidably connected inside the second groove;

[0011] A fixing shell is fixedly connected to the outside of the fixing block, a locking block is slidably connected inside the fixing shell, and a spring is installed inside the fixing shell;

[0012] The fixing block is slidably connected to a peeling tube inside, and a slot is provided on the outside of the peeling tube, and the locking block engages with the slot.

[0013] A pull ring is installed at the end of the card block;

[0014] A groove is provided on the outer side of the stripping tube, and the cutter engages with the groove;

[0015] The end of the stripping tube is fixedly connected to a flared tube.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a starting motor to drive the first gear to rotate, which in turn drives the second gear to rotate. The rotation of the second gear causes the slide rod to move, which in turn causes the telescopic rod to extend and retract, thereby extending and retracting the cutter. This enables the rapid removal of the fixed wire shielding mesh, resulting in a clean cut.

[0018] 2. This utility model allows the locking block to separate from the locking groove by pulling the pull ring, so that the stripping tube can be removed for replacement. For different types of wires, the internal copper wire diameter is different, and the stripping tube needs to be replaced quickly, which greatly improves work efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4 A shielded wire mesh stripping device includes a base plate 1, which supports and stabilizes the stripping device. A fixing frame 3 is fixedly connected to the top of the base plate 1. A shearing structure is installed inside the fixing frame 3. The fixing frame 3 protects the internal shearing structure and reduces the impact of the external environment on the structure. The shearing structure shears and strips the shielded wire mesh.

[0028] A support block 11 is fixedly connected to the top of the base plate 1, and a fixing block 12 is fixedly connected to the outside of the support block 11. A stripping tube 17 is slidably connected inside the fixing block 12. The stripping tube 17 separates the wires into layers, so that the copper wire is fixed inside the stripping tube 17 to prevent the shearing structure from damaging the copper wire. At the same time, the outer side of the stripping tube 17, which is fixed to the shielding mesh, is sheared and stripped by the shearing structure.

[0029] The shearing structure includes a drive assembly and a telescopic assembly. The drive assembly includes a motor 2, which is fixedly connected to the top of the base plate 1. The output end of the motor 2 is fixedly connected to a first gear 4. When the motor 2 is started, it drives the first gear 4 to rotate. The telescopic assembly includes a second gear 5. The first gear 4 meshes with the second gear 5. The first gear 4, driven by the motor 2, drives the second gear 5 to rotate. The second gear 5 is rotatably connected inside the fixed frame 3.

[0030] When the wire is fixed on the stripping tube 17, the second gear 5 is driven to rotate. The middle of the second gear 5 is slidably connected to the slide rod 7. The rotating second gear 5 drives the slide rod 7 to slide. The outside of the slide rod 7 is fixedly connected to the telescopic rod 8. The outside of the telescopic rod 8 is fixedly connected to the cutter 9. The moving slide rod 7 drives the telescopic rod 8 to extend and retract within the second gear 5. The telescopic rod 8 drives the cutter 9 to extend and retract, thereby achieving the cutting and stripping of the wire shielding mesh.

[0031] The second gear 5 has a first groove 6 and a second groove 10 in the middle. The slide rod 7 is slidably connected inside the first groove 6. The cutter 9 is slidably connected inside the second groove 10. The end of the peeling tube 17 is fixedly connected to the flared tube 20. The outer side of the peeling tube 17 has a cutting groove 19. The cutter 9 is engaged with the cutting groove 19.

[0032] When it is necessary to strip the wire shielding mesh, first separate the wire shielding mesh from the internal copper wire and insert it into the stripping tube 17. The shielding mesh is enlarged through the flaring tube 20 so that the shielding mesh is placed outside the stripping tube 17. Then, drive the shearing structure to cut the shielding mesh. The cutter 9 extends and retracts to fit with the cutting groove 19 to quickly and flatly cut and strip the shielding mesh.

[0033] Reference Figure 1 , Figure 2 and Figure 5 A fixed shell 13 is fixedly connected to the outside of the fixed block 12. The fixed shell 13 protects the internal structure. A locking block 14 is slidably connected inside the fixed shell 13. A pull ring 16 is installed at the end of the locking block 14. Pulling the pull ring 16 causes the locking block 14 to slide inside the fixed shell 13. A spring 15 is installed inside the fixed shell 13. The sliding locking block 14 squeezes the spring 15. A slot 18 is opened on the outside of the stripping tube 17. The locking block 14 engages with the slot 18.

[0034] When stripping the shielding mesh of a conductor, the diameter of the internal copper wire varies for different conductor models, and the length of the shielding mesh cut by different stripping tubes 17 also varies. It is necessary to select a suitable stripping tube 17. By pulling the pull ring 16, the locking block 14 slides and squeezes the spring 15, separating the locking block 14 from the locking groove 18, allowing the stripping tube 17 to be removed and replaced. Then, by releasing the pull ring 16, the locking block 14 rebounds under the action of the spring 15 and engages with the locking groove 18, fixing the stripping tube 17 and enabling quick replacement, which greatly improves work efficiency.

[0035] Working principle: When it is necessary to strip the wire shielding mesh, the diameter of the internal copper wire is different for different types of wires, and the length of the shielding mesh reserved by different stripping tubes 17 is different. It is necessary to select a suitable stripping tube 17. By pulling the pull ring 16, the locking block 14 slides and squeezes the spring 15, the locking block 14 separates from the locking groove 18, and the stripping tube 17 can be removed and replaced. Then, the pull ring 16 is released, and under the action of the spring 15, the locking block 14 springs back and engages with the locking groove 18 to fix the stripping tube 17 and achieve quick replacement.

[0036] Then, the wire shielding mesh is separated from the internal copper wire and inserted into the stripping tube 17. The shielding mesh is enlarged through the flared tube 20 so that the shielding mesh is placed outside the stripping tube 17. The motor 2 is started to drive the first gear 4 to rotate. The rotating first gear 4 drives the second gear 5 to rotate. The rotating second gear 5 drives the slide rod 7 to slide. The moving slide rod 7 drives the telescopic rod 8 to extend and retract inside the second gear 5. The telescopic rod 8 drives the cutter 9 to extend and retract. The telescopic cutter 9 fits with the cutting groove 19 to quickly and flatly cut and peel off the shielding mesh.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
