Description

Technical Field

[0001] This application relates to the field of cable splicing technology, and in particular to a high-efficiency cable splicer. Background Technology

[0002] Cable splicing is a core method for connecting cable conductors in power engineering and electrical installation. Its core principle is to physically twist the cores of two conductors together to create a mechanical interlock. Especially in production enterprises with high power loads, such as coal coking plants, a large number of cables are often laid to ensure the stable operation of numerous electrical devices. Cable splicing technology is used both during the initial cable laying process and during subsequent cable maintenance.

[0003] Traditional cable splicing involves workers first stripping a certain length of the cable's insulation using wire strippers or other stripping tools, then tightly wrapping the exposed portions of multiple cables together using twisting pliers or stranding pliers, and finally insulating the spliced ​​section with insulating tape. However, this method is not only inefficient but also increases the worker's operating time and labor intensity. Utility Model Content

[0004] This application provides a high-efficiency cable splicer that can effectively solve some problems existing in traditional manual cable splicing.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A high-efficiency cable splicer includes a metal rod, one end of which is provided with a connector for connecting to a power tool, and the other end of which is provided with a metal head;

[0007] The metal head has multiple arc-shaped slots evenly distributed along its circumference, and the center of the metal head has a through hole; the diameter of the arc-shaped slots is not less than the diameter of the single cable to be twisted.

[0008] An end cap is fixedly connected to the end of the metal head away from the metal rod body. The end cap has the function of stripping the insulation from the twisted cable.

[0009] Furthermore, the diameter of the end cap is larger than the diameter of the metal head, and the end cap is provided with a plurality of through holes along its circumference, and the adjacent sides of the plurality of through holes are interconnected. The number of through holes is the same as the number of arc-shaped slots, and their positions correspond one-to-one.

[0010] Furthermore, the edges of the insertion holes are all machined into cutting edges.

[0011] Furthermore, a necked portion is integrally formed between the metal rod body and the metal head, and the diameter of the circle formed by the multiple arc-shaped slots on the metal head that are close to each other is larger than the diameter of the necked portion.

[0012] Furthermore, a through hole is provided in the middle of the metal rod along its radial direction, and a tape fixing bracket is installed in the through hole.

[0013] Furthermore, the tape fixing bracket includes an L-shaped mounting bracket and a fixing rod with external threads. The fixing rod is inserted into the through hole on the metal rod, and the two ends of the fixing rod are respectively located on the outside of the two ends of the through hole.

[0014] One end of the fixing rod is fitted with a nut and the two are threaded together. The other end of the fixing rod is integrally formed with a stop cap. The stop cap is welded and fixed to the end of one section of the mounting bracket. The other section of the mounting bracket is parallel to one side of the metal head, and a bearing is installed at the end of this section of the mounting bracket. The plastic ring of the insulating tape can be fitted onto the outer ring of the bearing.

[0015] Furthermore, the shape and specifications of the connector are the same as those of the drill bit connector for an electric drill.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] Multiple cables to be spliced ​​are inserted into the various arc-shaped slots on the metal head of this application. The metal rod connected to the metal head is connected to the end of a power tool such as an electric drill or hand drill via a connector. When the electric drill or hand drill is started, the metal rod and the metal head will rotate together. During the rotation, the arc-shaped slots on the metal head will cause the cables in their respective slots to twist together, thereby achieving an automatic splicing effect. At the same time as splicing, the end cap at the end of the metal head can automatically strip the insulation from multiple cables to ensure that the spliced ​​cables are in a conductive state. Compared with the existing technology where workers manually splice cables, this method not only effectively improves splicing efficiency but also reduces the labor intensity of workers.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0025] like Figures 1-4 As shown, this application discloses a high-efficiency cable splicer, which includes a metal rod 1, one end of the metal rod 1 is provided with a connector 2 for connecting to a power tool, and the other end of the metal rod 1 is provided with a metal head 3.

[0026] The metal head 3 has multiple arc-shaped slots 4 evenly distributed along its circumference, and the center of the metal head 3 has a through hole 5; the diameter of the arc-shaped slots 4 is not less than the diameter of the single cable 13 to be twisted.

[0027] A metal head 3 is fixedly connected to an end cap 6 at the end away from the metal rod 1. The end cap 6 has the function of stripping the wires 13 to be twisted.

[0028] In the above embodiments, both the metal rod body 1 and the metal head 3 of this application are cylindrical and coaxially arranged. The power tool used to connect to the connector 2 on the metal rod body 1 can be a wired electric drill with replaceable drill bits or a wireless hand drill with replaceable drill bits. The arc-shaped groove 4 provided on the metal head 3 is used to place the cable 13 to be spliced.

[0029] When splicing of cables 13 with a number not exceeding the number of arc-shaped slots 4 is required, the user assembles the connector 2 on the metal rod 1 with the on-site power tool, and then inserts the multiple cables 13 to be spliced ​​into the multiple arc-shaped slots 4 on the metal head 3 of this application. After starting the power tool such as an electric drill or hand drill, the metal rod 1 and the metal head 3 will rotate together. During the rotation, the arc-shaped slots 4 on the metal head 3 will drive the cables 13 in their respective slots to twist together, thereby achieving the effect of automatic splicing. At the same time as splicing, the end cap 6 at the end of the metal head 3 can automatically strip the insulation of multiple cables 13 to ensure that the cables 13 are in a conductive state when spliced ​​together. Compared with the existing technology where workers manually splice the cables 13, this not only effectively improves the splicing efficiency, but also reduces the labor intensity of workers.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, the diameter of the end cap 6 is larger than the diameter of the metal head 3. The end cap 6 has multiple through holes 7 along its circumference, and the multiple through holes 7 are interconnected on their adjacent sides. The number of through holes 7 is the same as the number of arc-shaped slots 4, and their positions correspond one-to-one.

[0031] In the above embodiments, the number of arc-shaped slots 4 and the number of insertion holes 7 in this application are both four. The insertion holes 7 provided on the end cap 6 are, on the one hand, to facilitate the cable 13 to be twisted to be smoothly inserted into the side of the metal head 3 through the end cap 6, and on the other hand, to constrain the cable 13 during the rotation of the metal head 3, so as to prevent the part of the cable 13 to be connected from coming off the metal head 3 during the twisting process.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the edges of the through hole 7 are all machined into cutting edges 8.

[0033] In the above embodiments, the edges of the insertion holes 7 are all machined into cutting edges 8 with a certain sharpness. In use, the user inserts the part of the cable 13 to be twisted into the arc-shaped groove 4 on the side of the metal head 3 through the insertion hole 7 on the end cap 6. One worker fixes the other part of the cable 13, and another worker starts the power tool. During the rotation of the metal head 3, the part of the cable 13 located outside the end cap 6 is fixed by the worker, and the part inserted into the arc-shaped groove 4 will twist with the rotation of the metal head 3. During the twisting process of multiple cables 13, not only can the twisting effect be produced, but the cable 13 will also be cut by the cutting edge 8 on the edge of the insertion hole 7. Once the cutting edge 8 cuts the insulation layer on the surface of the cable 13, the edge of the insertion hole 7 will be embedded into the cable 13 sheath. As the cable 13 continues to twist, the edge of the insertion hole 7 will automatically push the cut insulation layer of the cable 13 off its metal part. In this way, the cable 13 splicer of this application can simultaneously complete the stripping operation of the insulation layer of the cable 13 during the splicing process, thereby improving the splicing speed of the cable 13.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, a necked section 9 is integrally formed between the metal rod body 1 and the metal head 3. The diameter of the circle formed by multiple arc-shaped slots 4 on the metal head 3 that are close to each other is larger than the diameter of the necked section 9.

[0035] In the above embodiments, the necking portion 9 provided between the metal rod body 1 and the metal head 3 in the manner described above can reduce the risk of the cable 13 being obstructed when the cable 13 is inserted into the arc-shaped slot 4 on the metal head 3.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, a through hole 10 is provided in the middle of the metal rod 1 along its radial direction, and a tape fixing bracket 11 is installed in the through hole 10.

[0037] In the above embodiments, the tape fixing bracket 11 added to the metal rod 1 can be used to install the insulating tape 12, so that the insulating tape 12 can be wrapped around the hinge area of ​​the cable 13 at the same time during the process of hinged splicing of the cable 13.

[0038] Furthermore, such as Figures 1-4 As shown, the tape fixing bracket 11 includes an L-shaped mounting bracket 111 and a fixing rod 112 with external threads. The fixing rod 112 is inserted into the through hole 10 on the metal rod body 1, and the two ends of the fixing rod 112 are located on the outside of the two ends of the through hole 10, respectively.

[0039] One end of the fixing rod 112 is fitted with a nut 114 and the two are threaded together. The other end of the fixing rod 112 is integrally formed with a stop cap 113. The stop cap 113 is welded and fixed to the end of one section of the mounting bracket 111. The other section of the mounting bracket 111 is parallel to one side of the metal head 3, and the end of this section of the mounting bracket 111 is fitted with a bearing 115. The plastic ring of the insulating tape 12 can be fitted onto the outer ring of the bearing 115.

[0040] In the above embodiments, the bearing 115 on the mounting bracket 111 is located on one side of the metal head 3, and the axis of the bearing 115 is parallel to the axis of the metal head 3. The inner ring of the bearing 115 can be welded and fixed to the mounting bracket 111 during manufacturing. The outer ring diameter of the bearing 115 is equal to the inner diameter of the plastic ring (or paper support ring) inside the commonly used insulating tape 12 that provides support, or the outer ring diameter of the bearing 115 is slightly smaller than the plastic ring (or paper support ring) inside the insulating tape 12. In this way, after the user puts the insulating tape 12 on the outer ring of the bearing 115, the insulating tape 12 can have a tight fit with the outer ring of the bearing 115, thereby reducing the risk of it coming off the bearing 115. One end of the L-shaped mounting bracket 111 is welded to the cap 113 at one end of the fixing rod 112. The other end of the fixing rod 112 passes through the through hole 10 on the metal rod body 1 and is fixed to the metal rod body 1 by the nut 114. When the metal rod body 1 rotates, the insulating tape 12 on the mounting bracket 111 can automatically wrap around the outside of the cable 13 to be twisted, thereby realizing the automatic insulation wrapping operation of the twisted cable 13.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, the shape and specifications of connector 2 are the same as those of the drill bit connector for electric drills.

[0042] In the above embodiments, the shape and specifications of the connector 2 of this application are set to be the same as the shape and specifications of the drill bit connector end of the electric drill. In this way, when the cable 13 splicer of this application is needed, the user can assemble the cable splicer of this application and the electric drill together by referring to the installation method of ordinary electric drill bits, which will make it easier to use.

[0043] The implementation principle of this embodiment is as follows: When multiple cables 13 need to be spliced, the user first assembles the connector 2 on the metal rod 1 and the electric drill together (the specific operation method can refer to the traditional electric drill bit installation method), and then inserts the multiple cables 13 to be spliced ​​through the multiple through-holes on the end cap 6 into the multiple arc-shaped slots 4 on the metal head 3 respectively. The part of the cable 13 inserted into the arc-shaped slot 4 is not less than the length of splicing required. After all cables 13 are inserted, a worker uses pliers or similar tools to clamp and secure the portion of each cable 13 located on the end cap 6 away from the metal rod 1. The free end of the insulating tape 12 on the mounting bracket 111 is then attached to the outside of these cables 13. Next, another worker starts a hand drill, which drives the metal rod 1 and the metal head 3 to rotate together. During this rotation, the arc-shaped slots 4 on the metal head 3 cause the cables 13 within their respective slots to intertwine. As the worker with pliers pulls the cables 13 away from the hand drill, the cables 13 automatically twist together as they pass through the rotating metal head 3. Simultaneously, the cutting edge 8 on the edge of the insertion hole 7 on the end cap 6 automatically strips the insulation from the cables 13, ensuring the twisted cables are conductive. Furthermore, the insulating tape 12 simultaneously insulates the twisted cables 13 during the rotation of the metal head 3. Compared to the existing technology where workers manually twist the cable 13, this method not only effectively improves twisting efficiency but also reduces the labor intensity of workers.
