Description

Technical Field

[0001] The utility model mainly relates to the field of subways, and particularly relates to a connector of an integral anti-theft type anti-eddy current terminal. Background Art

[0002] The stray current of the subway, also known as the eddy current of the subway, mainly refers to the current leaked from the subway train powered by direct current to the roadbed and its surrounding soil medium during the operation of the subway.

[0003] The eddy current of the subway mainly causes electrochemical corrosion to the buried metal pipelines, communication cables, steel bars in the main structures of stations and tunnels, and metal objects such as metal pipelines, brackets, and bridge frames with poor insulation from the tunnel. This electrochemical corrosion can not only shorten the service life of metal pipes and wires, but also reduce the strength and durability of the reinforced concrete main structure of the subway, and even lead to catastrophic accidents.

[0004] The eddy current drainage network is an important part of the stray current protection system. The eddy current protection system can measure and collect the stray current, provide a return channel for it, lead it back to the negative pole of the substation, and prevent the eddy current from leaking outside the subway system as much as possible.

[0005] The main function of the anti-eddy current terminal is to connect the drainage network steel bars into one body through its connection with the steel bars inside the roadbed. The anti-eddy current connector is to connect two adjacent anti-eddy current terminals, thus forming an eddy current collection and drainage network system.

[0006] The inventor found the following defects during the operation of specific embodiments:

[0007] At present, the anti-eddy current terminal connectors are basically processed by workers on the construction site. Using wire stripping tools and crimping tools, the cables and wire nose are crimped and assembled according to a certain length, and then the connector is fixed on the anti-eddy current terminal with bolts, flat gaskets, and spring gaskets. However, the on-site processing efficiency is not high, and the connector is made of copper, which is easy to lose on the construction site.

[0008] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0010] The utility model provides a connector of an integral anti-theft type anti-eddy current terminal to solve the technical problems existing in the above background art.

[0011] 2. Technical solutions:

[0012] To achieve the above object, the technical solution provided by the present utility model is: a connector for an integral anti-theft and anti-stray current terminal, including a connector head. The number of the connector heads is set to two. A cable is arranged between the two connector heads. A connecting plate is arranged on one side of the connector head. An installation hole is formed in the middle of the connecting plate, and an anti-theft bolt structure is arranged inside the installation hole;

[0013] The anti-theft bolt structure includes an anti-theft nut. An installation shaft is arranged at the bottom of the anti-theft nut. External threads are arranged on the outer wall of the installation shaft. A nut body is arranged at the top of the anti-theft nut. The nut body and the anti-theft nut are connected by a connecting block;

[0014] A first gasket is arranged on the top of the connecting plate. The first gasket is aligned with the installation hole. A second gasket is arranged on the top of the first gasket.

[0015] Further, a connecting groove is formed inside one side of the connector head. The inner wall of the connecting groove is attached to the outer wall of the cable.

[0016] Further, the installation shaft is arranged inside the installation hole, and the connecting block is in a frustum shape.

[0017] Further, an outer insulating layer is arranged on the outer wall of the cable. The outer insulating layer is made of rubber material.

[0018] 3. Beneficial effects:

[0019] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0020] The present utility model forms an integral structure with the anti-theft bolt structure and the cable. Then, the anti-theft bolt is inserted into the installation hole inside the connecting plate, and the anti-theft bolt body is connected to the anti-stray current terminal through a wrench. After the anti-theft bolt structure is fixed, continue to rotate to make the nut body separate from the anti-theft nut. The anti-theft nut requires a specific wrench to be disassembled, realizing the anti-theft of the connector;

[0021] After the connector head and the cable of the connector are processed in the factory, they are directly transported to the position of the subway track for installation. According to the distance between the internal steel bars of the two roadbeds, the length of the intermediate cable can be adjusted during the production process, realizing the rapid installation of the connector.
