Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable head processing, in particular to a cable head processing device for a high-voltage cable. Background Art
[0002] When the high-voltage cable is connected to the terminal or the cables are connected to each other, the outer protective layer (such as the insulating layer, the shielding layer, etc.) of the cable head is first stripped off, and then a cable connector for connection is made. In this process, the stripped wire core needs to be treated to prevent short circuits, wherein the roots of the wire cores are close and cannot be separated. The processing method of the prior art is to first embed a cone into the cable from the middle of each wire core to separate the roots of the wire cores, and then wrap sealant around the roots of each wire core, and finally sleeve a heat shrink tube or wrap an insulating tape around the outer surface of the root where the outer protective layer is stripped off. The above operation process is not only cumbersome and inefficient, but also the sealant wrapped around the root of the wire core is difficult to operate due to spatial position restrictions, which is time-consuming and easy to be loosely wound.

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] See also Figures 1 to 4 The utility model provides a technical solution: a cable head processing device for a high-voltage cable, comprising a high-voltage cable bundle 1 and a spacing sealing sleeve 2, the spacing sealing sleeve 2 is made of hard insulating plastic, the spacing sealing sleeve 2 is integrally injection molded by an injection molding machine, the high-voltage cable bundle 1 comprises an outer protective layer 101 and a cable core 102, a wire core sleeve hole 3 is arranged at the front end of the spacing sealing sleeve 2, the number of the wire core sleeve holes 3 and the cable core 102 is the same, the inner diameter of the wire core sleeve hole 3 is slightly larger than the outer diameter of the cable core 102, the wire core sleeve hole 3 can be pulled upward and outward to pull out the cable core 102 passing through it, a whole wire sleeve hole 4 is arranged at the rear end of the spacing sealing sleeve 2, a sealing cavity 5 is arranged in the middle position of the spacing sealing sleeve 2, the inner diameter of the whole wire sleeve hole 4 is slightly larger than the outer diameter of the high-voltage cable bundle 1, and the inner diameter of the bottom of the sealing cavity 5 is smaller than the outer diameter of the high-voltage cable bundle 1, A step is formed between the whole line socket hole 4 and the sealing cavity 5. When the interval sealing sleeve 2 is socketed with the high-voltage cable bundle 1, the step is required to contact the end face of the outer protective layer 101. At the same time, the lower end of the interval sealing sleeve 2 is fixed to the high-voltage cable bundle 1 by electrical tape. A glue hole 6 is opened on one side of the sealing cavity 5. A cone 7 is arranged on the side of the sealing cavity 5 close to the wire core socket hole 3. The shape of the cone 7 is wide at the top and pointed at the bottom. The lower end of the cone 7 is inserted into the middle of the high-voltage cable bundle 1. The upper end of the cone 7 separates the cable core 102 to avoid short circuit of the cable core 102. Sealant 8 is poured into the sealing cavity 5. The glue hole 6 is a threaded hole formed by later processing of the machine tool. When pouring glue, the glue hole 6 is connected to a joint 9 through a thread, and the joint 9 is connected to a glue pouring tube 10. The glue pouring tube 10 is connected to a glue pouring pump 11. When the glue pouring pump 11 is working, the sealant 8 is injected into the sealing cavity 5 to wrap the root of the cable core 102.
[0023] When in use, first peel off the outer protective layer 101 at the end of the high-voltage cable bundle 1 to expose the cable core 102, and further insert the spacing sealing sleeve 2 from the end of the cable core 102 into the root. In this process, all the cable cores 102 are inserted into the core sleeve holes 3 one by one. In the process of the spacing sealing sleeve 2 sliding toward the root of the cable core 102, the cable core automatically spreads outward under the guidance of the core sleeve holes 3, and the spreading angle is completely limited by the core sleeve holes 3. No manual adjustment is required, which can save a lot of time. Finally, the entire sleeve hole 4 is sleeved on the outer surface of the high-voltage cable bundle 1 and the cone 7 is also inserted into the interior of the high-voltage cable bundle 1. This operation realizes the simultaneous external insulation and internal separation of the cable core 102 and the angle adjustment of the cable core 102, which makes the process steps simple and can improve efficiency. The lower end of the spacing sealing sleeve 2 is further wrapped around the high-voltage cable bundle 1 with insulating tape, so that the spacing sealing sleeve 2 will no longer fall off the high-voltage cable bundle 1, and further through the joint 9 and the glue filling tube 10 and use the glue filling pump 11 to inject the sealant 8 into the sealing cavity 5. At this time, the sealant 8 is first poured at the root of the cable core 102. When the sealing cavity 5 is filled with glue, the pressure increases accordingly. The sealant 8 is mixed into the matching gap between the whole line socket hole 4 and the high-voltage cable bundle 1 under high pressure, and also penetrates into the interior of the cross-section of the high-voltage cable bundle 1, and also penetrates into the matching gap between the wire core socket hole 3 and the cable core 102. When the staff can see the sealing rubber oozing out from the periphery of the wire core socket hole 3 with the naked eye, the glue filling is stopped, and the joint 9 is further unscrewed and the sealing head is screwed in to wait for the sealant 8 to solidify, or the glue filling tube 10 is directly cut off and bent so that the sealant 8 cannot be discharged in reverse and wait for the sealant 8 to solidify before removing the joint 9. The cable head processing device makes the sealing cable and the material separating the cable core into an integrated type, so that the installation steps become simple and convenient to improve efficiency, and then the insulation at the root of the cable core is made by glue filling, which is not only fully sealed but also strong and will not fall off.
[0024] To sum up, the cable head processing device of the high-voltage cable makes the spacing sealing sleeve 2 for the external insulation structure and the cone 7 of the internal anti-short-circuit structure into an integrated structure and installs them synchronously to reduce the process steps. The work that requires manual opening of the wire core and adjustment of the angle is assisted by the preset wire core sleeve hole 3 so that the wire core can be quickly adjusted into place, thereby greatly simplifying the processing steps of the cable root and improving the processing efficiency of the cable head. The spacing sealing sleeve 2 is sleeved on the root of the wire core from which the outer protective layer 101 has been peeled off. At this time, a closed sealing cavity 5 is formed at the root, and then the sealant 8 is poured into the sealing cavity 5 through the glue pump 11. Not only can the root be quickly and completely filled with the sealant 8, but the solidified sealant 8 is also adhered to the root and will not fall off, so that the operation of the root insulation sealing is simple and fast and the sealing structure is strong.
