Description

Technical Field

[0001] This utility model relates to the field of cable assembly technology, and in particular to a wear-resistant cable assembly with a dual protection structure. Background Technology

[0002] In the field of cable assembly technology, copper and aluminum cables are often used together for different transmission scenarios due to differences in conductivity and cost. Both copper and aluminum cables are mostly equipped with wear-resistant layers to prevent the internal cables from being exposed after long-term use. When connecting copper and aluminum cables, connectors of different materials on both sides are usually used to connect the bare wires of the copper and aluminum cables to achieve transmission. Although the surface of the cable has its own wear-resistant properties, the existing connectors have simple protective structures in practical applications. Most connectors only support connection, which may lead to exposed cables and weak waterproof performance. The gaps at the connection points are prone to water ingress, posing a safety hazard. Moreover, the connection points between copper and aluminum cables are mostly fixed with bolts or simple clamping structures, which are prone to loosening due to vibration and thermal expansion and contraction during long-term use. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies. However, existing connectors have a simple protective structure in practical applications. Most connectors only support connection, which may lead to exposed cables and weak waterproof performance. Water can easily enter through the gaps at the connection points, posing a safety hazard. Furthermore, the connection points between copper and aluminum cables are mostly fixed with bolts or simple clamping structures, which are prone to loosening due to vibration and thermal expansion and contraction during long-term use. This utility model provides a wear-resistant cable assembly with a dual protective structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant cable assembly with a dual protective structure, comprising a copper cable, an aluminum cable on one side of the copper cable, a partition on the outer surface of the aluminum cable, a first connecting base plate fixedly connected to one side of the partition, a first fixing head fixedly connected to one side of the first connecting base plate, a fixing structure on one side of the first fixing head, the fixing structure including a release port, a first threaded block fixedly connected to one side of the release port, a first fixing plate fixedly connected to one side of the first threaded block, a first spring fixedly connected to the outer surface of the first fixing plate, and a nut threadedly connected to the outer surface of the first threaded block.

[0005] In a preferred embodiment, a second fixing head is fixedly connected to the other side of the first connecting base plate, and a connecting structure is provided on the other side of the relaxation port.

[0006] In a preferred embodiment, the inner wall of the first fixing head is provided with a movable opening, and the inner wall of the movable opening is slidably connected to the outer surface of the first fixing plate.

[0007] In a preferred embodiment, the connection structure includes a second threaded block, one side of which is fixedly connected to the other side of the release opening.

[0008] In a preferred embodiment, a second fixing plate is fixedly connected to one side of the second threaded block, and a second spring is fixedly connected to the top of the first fixing plate.

[0009] In a preferred embodiment, the top of the second spring is fixedly connected to the inner wall of the second fixing head, and a fixing post is fixedly connected to the bottom of the second fixing plate.

[0010] In a preferred embodiment, the inner wall of the second fixing head is provided with a moving groove, and the bottom of the moving groove is provided with a positioning port.

[0011] In a preferred embodiment, the inner wall of the positioning port and the inner wall of the fixing column are slidably connected.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This utility model features a first connecting base plate and symmetrically arranged second connecting base plates. The first and second connecting base plates are made of the same material as the copper and aluminum cables, respectively, achieving a connection and transmission effect. Simultaneously, it protects the cables connected to the inside of the first and second connecting base plates. A partition separates the two connecting base plates. A first fixing head and a movable opening facilitate downward movement of the first fixing head, clamping it onto the outer surface of the cable. A nut and a first threaded block press the first fixing head downward when the nut is screwed onto the first threaded block, thus clamping the bottom of the first fixing head onto the cable surface in conjunction with the first connecting base plate. This simplifies the installation of the connector, reduces the need for bolts, and provides higher cable protection. A first spring automatically pulls the first fixing head to release the clamping state when the nut moves backward to the release opening, facilitating disassembly. A rubber pad is fixedly connected to the side of the nut near the first fixing head to prevent water ingress into the movable opening, providing waterproof protection for the inside of the cable. Clamping teeth on the lower surface of the first fixing plate ensure a tighter and more stable clamping. Attached Figure Description

[0022] 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.

[0023] Example 1

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: a wear-resistant cable assembly with a double protection structure, including a copper cable 1, an aluminum cable 2 on one side of the copper cable 1, a partition 3 on the outer surface of the aluminum cable 2, a first connecting base plate 4 fixedly connected to one side of the partition 3, a first fixing head 5 fixedly connected to one side of the first connecting base plate 4, a fixing structure 6 on one side of the first fixing head 5, the fixing structure 6 including a loosening port 61, a first threaded block 62 fixedly connected to one side of the loosening port 61, a first fixing plate 63 fixedly connected to one side of the first threaded block 62, a first spring 64 fixedly connected to the outer surface of the first fixing plate 63, a nut 7 threadedly connected to the outer surface of the first threaded block 62, a second fixing head 8 fixedly connected to the other side of the first connecting base plate 4, a connecting structure 9 on the other side of the loosening port 61, and a movable port opened on the inner wall of the first fixing head 5, the inner wall of the movable port and the outer surface of the first fixing plate 63 being slidably connected.

[0025] In this embodiment, a first connecting base plate 4 is provided, and a second connecting base plate 4 is symmetrically provided. The first connecting base plate 4 and the second connecting base plate are made of the same material as the copper cable 1 and the aluminum cable 2, respectively, thereby achieving the effect of connection and transmission. At the same time, the cables connected to the inside of the first connecting base plate 4 and the second connecting base plate on both sides are protected. By providing a partition 3, the connecting base plates on both sides can be separated. The first fixing head 5 and the moving port are provided to facilitate the downward movement of the first fixing head 5, thereby clamping it on the outer surface of the cable. The nut 7 and the first threaded block 62 are provided so that when the nut 7 is screwed into the first threaded block 62, the first fixing head 5 is pressed downward, so that the bottom of the first fixing head 5 is clamped on the surface of the cable in cooperation with the first connecting base plate 4. This makes the installation of this connector simpler, reduces the need for bolt fixing, and provides higher protection for the cable. The first spring 64 is provided so that when the nut 7 moves backward to the loosening port 61, it automatically pulls the first fixing head 5 to release the clamping state, making it easy to remove.

[0026] In addition, a rubber pad is fixedly connected to the side of the nut 7 near the first fixing head 5 to prevent water from entering the inside of the moving port and to provide waterproof protection for the inside of the cable. The lower surface of the first fixing plate 63 is provided with clamping teeth to make the clamping more secure and stable.

[0027] Example 2

[0028] like Figure 1-4 As shown, the connecting structure 9 includes a second threaded block 91, one side of the second threaded block 91 and the other side of the relaxation port 61 are fixedly connected, a second fixing plate 92 is fixedly connected to one side of the second threaded block 91, a second spring 93 is fixedly connected to the top of the first fixing plate 63, the top of the second spring 93 is fixedly connected to the inner wall of the second fixing head 8, a fixing post 94 is fixedly connected to the bottom of the second fixing plate 92, a moving groove is provided on the inner wall of the second fixing head 8, a positioning port 10 is provided at the bottom of the moving groove, and the inner wall of the positioning port 10 and the inner wall of the fixing post 94 are slidably connected.

[0029] In this embodiment, the nut 7 and the rubber pad are also provided on the surface of the second threaded block 91, which facilitates the pressing down of the second fixing plate 92 and its movement in the moving groove. The positioning port 10 is provided so that when the fixing post 94 follows the second fixing plate 92 down, it can pass through the second fixing head 8 and press on the top of the cable with the internal stripped insulation layer to prevent the cable from moving backward. It works in conjunction with the first fixing plate 63 to make the connected cable more stable and less likely to fall off.

[0030] Working principle:

[0031] like Figure 1-4As shown, during actual installation, firstly, the insulation layer of one end of the copper cable 1 and the aluminum cable 2 is stripped to expose the internal conductors. Then, they are passed through the first fixing head 5 and the second fixing head 8 respectively, and placed in the corresponding positions of the first connecting base plate 4 and the second connecting base plate. Next, the nut 7 is rotated to move inward along the first threaded block 62 and the second threaded block 91. The nut 7 on the other side is operated in the same way. The two nuts 7 push the first fixing plate 63 and the second fixing plate 92 to slide downward along the moving opening and the moving groove. At this time, the first spring 64 and the second spring 93 are stretched. The clamping teeth at the bottom of the first fixing plate 63 cooperate with the first connecting base plate 4 to clamp the conductor of the copper cable 1 (the position with the insulation layer). The fixing post 94 at the bottom of the second fixing plate 92 passes through the positioning opening 10 to press the conductor of the aluminum cable 2, thus achieving double fixing.

[0032] When disassembly is required, rotate the nuts 7 on both sides in the opposite direction to the release port 61 position. The first spring 64 and the second spring 93 will rebound, driving the first fixing plate 63 and the second fixing plate 92 to reset, thereby releasing the clamp on the cable.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
