Description

Technical Field

[0001] The present invention relates to the technical field of cable development.

[0002] In particular, the present invention relates to a cable and a cable cutting element. Background Art

[0003] Cables play an irreplaceable role in the transmission of power and information, and have an important impact on people's daily life and production. Since the manufacturing and use of cables are very large, and there are many types of cables, the performance of the cables must be tested before use to confirm whether they meet the conditions of use. When testing cables, a certain length of cable sample is generally selected, and the insulation layers at both ends are stripped and removed to expose the core wire of the cable for relevant tests.

[0004] At present, the outer skin of the cable is mainly stripped manually with a utility knife. This device has the problems of high labor intensity, very low efficiency, and easy damage to the wire core in the cable. In order to solve these problems, a cable outer skin stripping device is usually required. However, the existing cable outer skin stripping device can only strip the outer skin of some thin-caliber cables with thin outer skin. For some large-caliber cables with thick outer skin, the existing cable outer skin stripping device cannot strip the outer skin of them. Summary of the invention

[0005] The object of the present invention is to provide a cable and a cable cutting piece which are simple in structure, convenient for cutting the cable, effectively cut the outer layer of the cable, and are suitable for cutting cables of various specifications.

[0006] In order to solve the above problems, the present invention is implemented by adopting the following technical solutions:

[0008] Preferably, the slide groove comprises a first slide groove and a second slide groove, and both the first slide groove and the second slide groove are extended in the axial direction.

[0009] Further preferably, the connecting pin includes a first connecting pin and a second connecting pin connected to the first sliding groove, and a third connecting pin and a fourth connecting pin connected to the second sliding groove.

[0010] Further preferably, the connecting foot is provided with a thread.

[0011] Further preferably, at least a portion of the connecting leg is arc-shaped.

[0012] Further preferably, at least a portion of the limiting pad is arc-shaped.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example: Figure 1The figure is only one embodiment of the present invention, a cable and a cable cutting piece, comprising a cable 1, a protective layer 2 and a cutting device 3 arranged around the outside of the protective layer 2, a limiting pad 11 is arranged between the cable 1 and the protective layer 2, the cutting device 3 is connected to the protective layer 2 through a connecting foot 31, the protective layer 2 is provided with a slide groove 21 for facilitating the sliding of the connecting foot 31, the cutting device 3 is provided with a locking bolt 32 for locking the connecting foot 31, the cutting device 3 is provided with a blade 33 and an annular groove 34 for fixing the blade 33.

[0024] First, the slide groove 21 on the protective layer 2 of the cable is used to fix the connecting foot 31 and thus fix the entire cutting device 3, so that the cutting device 3 can slide along the direction in which the slide groove 21 extends. The slide groove 21 extends along the axial direction, so the cutting device 3 can slide along the axial direction and start cutting when it reaches the part of the cable that needs to be cut.

[0025] It should be noted here that the connecting foot 31 can slide freely to adapt to the cutting of cables of different specifications. When the specifications of the cable change, the position of the connecting foot 31 also changes accordingly until the connecting foot 31 can just rest against the slide groove 21. At this time, tighten the locking bolt 32 to lock the connecting foot 31. The connecting foot 31 has threads, which can facilitate the movement of the connecting foot 31 and make it more convenient for the locking bolt 32 to fix the connecting foot 31.

[0026] Next is the annular groove 34 on the cutting device 3, in which a blade 33 can be fixed so that the blade can cut the cable. Of course, the number of the blade 33 is at least one. In fact, many groups of blades are arranged at intervals on the annular groove 34 to perform circumferential cutting on the protective layer 2 of the cable.

[0027] Finally, there is the cable 1. A limit pad 11 is set between the cable 1 and the protective layer 2 to ensure that the cable 1 does not slide randomly. The cable 1 structure is more stable and will not deform during cutting. Of course, the most important thing is that a sensor device 12 is set on the limit pad 11. When the blade 33 cuts the cable to the sensor device 12, the sensor device 12 can sound an alarm to indicate that the cutting is completed. No cutting damage will be caused to the core wire.

[0028] In addition, the cable and the cable cutting piece of the present invention also have the following designs:

[0029] The slide slot 21 includes a first slide slot 211 and a second slide slot 212, and the first slide slot and the second slide slot are both extended in the axial direction. Meanwhile, the connecting pin 31 includes a first connecting pin 311 and a second connecting pin 312 connected to the first slide slot 211, and a third connecting pin 313 and a fourth connecting pin 314 connected to the second slide slot 212.

[0030] With a structure of multiple slide grooves 21 and multiple connecting feet 31 in each slide groove 21, the connection between the connecting feet 31 and the slide groove 21 is more stable, the connection between the cutting device 3 and the protective layer 2 is tighter, and it is more convenient to cut the cable.

[0031] At the same time, at least a part of the connecting foot 31 is arc-shaped. The end where the connecting foot 31 and the slide slot 21 are connected is arc-shaped, and the curvature is the same as the curvature of the slide slot 21, so that the connection between the connecting foot 31 and the slide slot 21 is more suitable, and no relative movement will occur after being fixed.

[0032] At least a part of the limiting pad 11 is arc-shaped. It is convenient for the limiting pad 11 to fit with the protective layer 2. The limiting pad 11 has a good anti-extrusion ability. The limiting pad 11 is arranged between the cable 1 and the protective layer 2, which plays a buffering role when the cable is squeezed. Due to the arc structure of the limiting pad 11, a part of the cable 1 can be wrapped, and the stress is fully dispersed to the periphery of the cable when squeezed. Moreover, the limiting pad 11 can effectively prevent the displacement of the cable 1 when it is bent and squeezed, causing the cables 1 to all shift to the same side of the cable, causing mutual squeezing and damage between the cables 1.

[0033] The number of the sensing devices 12 is the same as the number of the limiting pads 11. A fixing groove for fixing the sensing devices 12 is provided in the protective layer 2.

[0034] The cable 1 is provided with a polyurethane material layer outside, which plays a good insulation and waterproof function.

[0035] The cable and the cable cutting piece of the present invention have simple structures, are convenient for cutting the cable, effectively cut the outer layer of the cable, and are suitable for cutting cables of various specifications.

[0036] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
