Description

Technical Field

[0002] Good cable accessories are a guarantee for the safe and efficient operation of cables. The cable head with good cable accessories manufacturing process is equivalent to the service life of the cable body. During the manufacturing process, the surface of the conductor and the insulator cannot be made smooth enough to even out the electric field strength on the surface of the conductor and the insulator. Therefore, a semi-conductive shielding layer is placed on the surface of the conductor and the insulator to achieve this goal. The chamfering of the semi-conductive shielding layer to a smooth and smooth surface is the effect of uniform electric field and preventing moisture from entering the insulation layer. The existing method is mostly to use a cable chamfering tool to enable the operator to cut the cable shielding layer.

[0041] Please refer to Figures 1 to 3 As shown, it shows the specific structure of the first preferred embodiment of the utility model, which includes a base 10, a pressure plate 20, a blade 30 and a locking assembly 40.

[0042] The base 10 includes a bottom plate 11 and a main body plate 12 which are integrally bent and formed. The bottom plate 11 is provided with connecting grooves 101 which are spaced apart from each other in the front and back. In the present embodiment, the connecting grooves 101 are divided into two groups which are spaced apart from each other in the front and back, and each group of connecting grooves 101 is divided into two groups which are symmetrically arranged in the transverse direction. The main body plate 12 is provided with a first locking hole 102.

[0043] The lower end of the pressing plate 20 integrally extends downward to form a first connecting portion 21 that cooperates with the connecting groove 101. The pressing plate 20 and the base 10 are surrounded to form a receiving cavity 201 that cooperates with the cable. The upper end of the pressing plate 20 and the main plate 12 are locked together to fix the cable in the receiving cavity 201. In this embodiment, the first connecting portions 21 are two symmetrically arranged laterally. Through the two first connecting portions 21 and the connecting groove 101, the pressing plate 20 is prevented from shaking left and right during cutting, thereby ensuring the cutting effect. An interference portion 22 is integrally extended outward from one side of the pressure plate 20, and a convex portion 23 is integrally provided on the interference portion 22 toward the accommodating cavity 201; the lower end of the first connecting portion 21 is integrally bent to form a limiting portion 211, and the limiting portion 211 contacts the lower end of the side wall of the connecting groove 101, so that the pressure plate 20 is prevented from sliding up and down during the cutting process through the limitation between the limiting portion 211 and the connecting groove 101, thereby ensuring the stability of the cutting process; a second locking hole 202 is opened at the upper end of the pressure plate 20 to cooperate with the first locking hole 102.

[0044] The blade 30 is arranged on the pressure plate 20 and is located in the accommodating cavity 201; in the present embodiment, the blade 30 is arranged on the other side of the pressure plate 20, so that when working, the protrusion 23 contacts with the cable, so that the other side of the pressure plate 20 is tilted toward the cable direction, thereby driving the blade 30 on the other side to tilt toward the cable, which is convenient for the cutting process of the blade 30; in the present embodiment, the blade 30 is fixedly installed on the pressure plate 20 by a first fixing bolt 31, a second fixing bolt 32 and a fixing plate 33, the first fixing bolt 31 is arranged on the pressure plate 20 and presses one side of the blade 30, the second fixing bolt 32 is two arranged at intervals, and the two second fixing bolts 32 are both arranged on the pressure plate 20, the fixing plate 33 is pressed toward the pressure plate 20 by the two second fixing bolts 32, and the other side of the blade 30 is clamped between the fixing plate 33 and the pressure plate 20, so that it is convenient for the installation and disassembly process of the blade 30, and the installation and maintenance process is also more convenient.

[0045] The two ends of the locking assembly 40 are respectively connected between the main body plate 12 and the pressure plate 20 and lock the upper end of the pressure plate 20 with the main body plate 12; in this embodiment, the two ends of the locking assembly 40 respectively lock the upper end of the pressure plate 20 on the main body plate 12 through the cooperation of the first locking hole 102 and the second locking hole 202; the locking assembly 40 includes a locking bolt 41 and a locking nut 42, the locking bolt 41 passes through the first locking hole 102 and the second locking hole 202 in sequence, one end of the locking bolt 41 contacts the outer wall of the main body plate 12, and the locking nut 42 is locked at the other end of the locking bolt 41 and contacts the outer wall of the pressure plate 20; the locking assembly 40 also includes a limiting nut 43, which is locked on the locking bolt 41 and is located on the inner side wall of the main body plate 12. The limiting nut 43 is used to prevent the locking bolt 41 from falling off from the main body plate 12 after the locking nut 42 is screwed off.

[0046] The method of using this embodiment is described in detail as follows;

[0047] When in use, first unscrew the locking nut 42, and then extend the first connecting part 21 into the corresponding connecting groove 101 according to the diameter of the cable to be processed. At this time, let the cable pass through the accommodating cavity 201, and tighten the locking nut 42, so that the pressure plate 20 presses the cable. At the same time, through the interference between the protrusion 23 and the cable, the blade 30 is tilted toward the direction of the cable. Then the operator drives the product to rotate around the cable. At this time, the blade 30 cuts close to the shielding layer of the cable, thereby completing the chamfering process of the cable shielding layer. After cutting, loosen the locking nut 42, and then take the cable out of the accommodating cavity 201.

[0048] Please refer to Figures 4 to 5As shown, it shows the specific structure of the second preferred embodiment of the utility model, which is basically the same as the structure of the first preferred embodiment mentioned above, and the difference is:

[0049] In this embodiment, it also includes a core sleeve 50, which is clamped in the accommodating cavity 201 and sleeved on the external core. When cutting the insulation layer of the cable, it is necessary to set the chamfering knife sleeve on the core. Since the core generally has multiple strands of cores wound together, the surface is relatively rough and not smooth enough. If the chamfering knife sleeve is directly set on the core, vibration will be generated during the cutting of the insulation layer, thereby affecting the cutting effect of the insulation layer. Through the setting of the core sleeve 50, the core sleeve can be sleeved on the core when cutting the insulation layer, so that the rotation process of the chamfering knife on the core is smoother, ensuring the cutting effect of the insulation layer; it also includes an adjustment plate 60, which The lower end of the section plate 60 is integrally bent to form a second connecting portion 61 that cooperates with the connecting groove 101. The upper end of the adjusting plate 60 is provided with a through groove 601 for the locking assembly 40 to pass through. An adjusting cavity 602 is formed between the adjusting plate 60 and the base 10. The wire core sleeve 50 is clamped in the adjusting cavity 602. Since the wire core diameter is smaller than the insulation layer diameter, the diameter of the wire core sleeve 50 will also be correspondingly smaller. The original accommodating cavity 201 is larger in size, and when cutting the insulation layer of the wire core with a smaller size, it is easy to fail to clamp the wire core sleeve 50. Therefore, the setting of the adjusting plate 60 is used to reduce the size of the accommodating cavity 201 so that it can meet the cutting process of smaller-sized wire cores.

[0050] There are two connecting grooves 101 arranged symmetrically in transverse direction, and correspondingly, there are two first connecting parts 21 arranged symmetrically in transverse direction, and grooves 203 are recessed inwardly on the outer sides of the two first connecting parts 21; a locking member 24 is provided on the pressure plate 20, and the locking member 24 includes a main body 241, a buckle portion 242 integrally bent and formed at one end of the main body 241, and an elastic portion 243 integrally bent and formed at the other end of the main body 242, and the buckle portion 242 and the elastic portion 243 are respectively buckled in the corresponding grooves 203, so that the main body 242 seals the opening between the two first connecting parts 21 to prevent the two first connecting parts from falling off from the connecting groove 101.

[0051] The design focus of the utility model is that connecting grooves arranged at intervals in front and behind are opened on the bottom plate, and a first connecting part that cooperates with the connecting grooves is integrally extended downward from the lower end of the pressing plate, and a accommodating cavity that cooperates with the cable is formed between the pressing plate and the base, so that when cutting the cable shielding layer, the first connecting part can be selected to extend into the corresponding connecting groove for cables of different diameters, thereby adjusting the distance between the bottom plate and the pressing plate, thereby adjusting the size of the accommodating cavity, so that it can meet the cutting process of cables of more sizes, with fewer limitations on use, and at the same time, there is no need to use multiple chamfering knives of different specifications, thereby reducing the cost of use.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
