Description

Technical Field

[0001] This utility model relates to connectors, specifically to a sleeve connector for pre-embedded cables. Background Technology

[0002] High-speed cables are laid underground, which is cheaper than overhead deployment. Also, because high-speed cables avoid cities, the surrounding area will not be developed, and there is no risk of them being dug up.

[0003] During the installation process, connectors, or wiring harnesses, are needed to connect the laid cables. However, existing wiring harnesses are typically wrapped around fixing screws and then tightened onto a metal connector plate. The biggest problem with this wiring method is that the fixing screws can loosen due to cable movement. Utility Model Content

[0004] The purpose of this invention is to provide a sleeve connector for pre-embedded cables to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sleeve connector for pre-embedded cables, comprising:

[0006] The first terminal block has a circular array of iron pillars arranged on it. One end of the iron pillars extending to one side of the first terminal block is a threaded connection part, and the other end extending to the other side of the first terminal block is a conductive part.

[0007] The second terminal block has a circular array of iron pillars arranged on it. One end of the iron pillars extending to one side of the second terminal block is a threaded connection part, and the other end extending to the other side of the second terminal block is a plug-in part.

[0008] The winding nut has a slot at one end of its cross-section and also includes a cross-shaped conical winding member inserted into the slot. The winding nut is threadedly connected to the threaded connection part.

[0009] Preferably, the winding nut has an internal thread.

[0010] Preferably, the threaded connection part is a hollow structure with a limiting groove on its inner wall, and the limiting groove is inserted into the cross-shaped conical winding part.

[0011] Preferably, the port of the plug portion is symmetrically provided with elastic arc-shaped metal pieces, and two of the elastic arc-shaped metal pieces are inserted into the conductive portion so that the elastic arc-shaped metal pieces press against the inner wall of the plug portion.

[0012] Preferably, the assembly also includes a cylindrical body, wherein the first terminal block and the second terminal block are inserted from both ends of the cylindrical body and are threadedly connected after being inserted into the conductive part and the insertion part.

[0013] Preferably, a lead wire cover is also included, through which the wire fixed to the winding nut passes and is threadedly connected to the cylindrical body.

[0014] In the above technical solution, the sleeve connector for pre-embedded cables provided by this utility model has the following beneficial effects: the cable is passed through the winding nut, and then the exposed copper wire is passed through the cross-shaped conical winding piece and wrapped around it. Then the winding nut is inserted, and finally the winding nut is threaded to the threaded connection part. The inserted cross-shaped conical winding piece will also be deformed due to the compression of the inner wall of the threaded connection part, so that it is in a state of being subjected to a reverse force under pressure deformation.

[0015] Then, the wired cable is connected by inserting it into the threaded connection part on the first and second terminal blocks. Compared with the traditional wiring method, there will be no loosening caused by the threaded connection. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a sleeve connector for pre-embedded cables includes:

[0026] The first terminal block 1 is provided with iron pillars arranged in a circumferential array. One end of the iron pillars extending to one side of the first terminal block 1 is a threaded connection part 21, and the other end extending to the other side of the first terminal block 1 is a conductive part 22.

[0027] The second terminal block 3 is provided with iron pillars arranged in a circular array. One end of the iron pillars extending to one side of the second terminal block 3 is a threaded connection part 21, and the other end extending to the other side of the second terminal block 3 is a plug-in part 23.

[0028] The winding nut 4 has a slot at one end of its cross section and also includes a cross-shaped conical winding member 41 inserted into the slot. The winding nut 4 is threadedly connected to the threaded connection part 21.

[0029] Specifically, this also includes the cylinder 5 (PVC pipe fitting) and the lead wire cover 6 (PVC pipe fitting). The cable is then passed through the lead wire cover 6, and the winding nut 4 is used. After completion, hot melt resin or foaming liquid is injected to seal the connection between the cable and the lead wire cover 6. Excess cable can be bent and stored inside the lead wire cover 6. The first terminal block 1 and the second terminal block 3 are inserted from both ends of the cylinder 5, respectively, and are in the state of being inserted into the conductive part 22 and the insertion part 23. As the insertion continues, the first terminal block 1 and the second terminal block 3 enter the port of the cylinder 5 and are threadedly connected to the internal threads within the port. The first terminal block 1 and the second terminal block 3 rotate in the same direction. With the threaded connection, the conductive part 22 and the insertion part 23 continue to be inserted.

[0030] A rubber gasket is installed at the port of the cylinder 5 to ensure the sealing of the cylinder 5 and the lead wire cover 6 after assembly, and to prevent short circuits caused by internal water overflow after pre-embedding.

[0031] In the above technology, the cable is passed through the winding nut 4, and then the exposed copper wire is passed through the cross-shaped conical winding member 41 and wound around it. Then the winding nut 4 is inserted, and finally the winding nut 4 is threadedly connected to the threaded connection part 21. The inserted cross-shaped conical winding member 41 will also be deformed due to the compression of the inner wall of the threaded connection part 21, thus being in a state of being subjected to a reverse force under pressure deformation.

[0032] Then, the cable with completed wiring is connected by inserting the plug-in part 23 on the first terminal block 1 and the second terminal block 3 into the threaded connection part 21. Compared with the traditional wiring method, there will be no loosening caused by the threaded connection.

[0033] As a further embodiment of this utility model, the winding nut 4 has an internal thread. The port of the insertion part 23 is symmetrically provided with elastic arc-shaped metal pieces 231, and the conductive part 22 is inserted into two elastic arc-shaped metal pieces 231, so that the elastic arc-shaped metal pieces 231 press against the inner wall of the insertion part 23. This achieves the embedding and fixing of the conductive part 22 and the insertion part 23 after insertion, and the locking effect is achieved due to the embedding of the elastic arc-shaped metal pieces 231.

[0034] As a further embodiment of this utility model, the threaded connection part 21 has a hollow structure, and a limiting groove 211 is formed on its inner wall. The limiting groove 211 is inserted into the cross-shaped conical winding part 41. Figure 1 As shown. It should be noted that the insertion slot is an annular slot.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
