Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a cable connector with a fixed snap-fit ​​structure to prevent detachment. Background Technology

[0002] In power transmission and distribution systems, cable joints are widely used in the main network system of ring main units and cable branch boxes or the ring network system of box-type transformers. As the connection of incoming and outgoing cables, they can be connected to busbars, or multiple combinations can be formed by connecting cable joints to form multiple circuits.

[0003] However, the existing cable joints have poor connection stability. With prolonged use, the joints are prone to falling off, thus losing their function of fixing and protecting the cable. Moreover, the falling off of cable joints is often due to the loosening of the cable and the separation of the cable joint. During long-term use, external factors pulling on the cable may cause the cable and the cable joint to separate. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-drop cable connector with a fixed snap-fit ​​structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable connector with a fixed snap-fit ​​structure to prevent detachment, comprising a connecting pipe, a plug pipe, and a cable. A reinforcing rib is provided in the middle of the surface of the connecting pipe. Plug-in cavities are opened at both ends of the connecting pipe. A plug pipe is provided inside each plug cavity. A cable is installed inside the plug pipe. Several threaded sleeves are evenly installed on the surface of the plug pipe. A lead screw is threadedly connected to the threaded sleeve. A rotating handle is connected to one end of the lead screw outside the plug pipe. A clamping plate is connected to the other end of the lead screw inside the plug pipe via a rotating shaft. A connecting block is provided on the surface of one end of the plug pipe. A connecting groove is opened at the bottom of the plug cavity. A sliding groove is opened at the bottom of the connecting groove. A locking groove is opened at the top of the sliding groove.

[0006] Preferably, the clamping plate is arc-shaped, the surface of the clamping plate is covered with a protective pad, and the clamping plate is in close contact with the surface of the cable.

[0007] Preferably, the size and position of the connecting groove correspond to the shape and size of the connecting block, and the connecting block engages and is fixedly connected with the engaging groove.

[0008] Preferably, a plurality of connecting springs are provided at the bottom of the inner cavity of the sliding groove, and a docking plate is connected to the top of the connecting spring. The docking plate is in contact with and slidably connected to the surface of the connecting block.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, the cable is fixed inside the plug tube, and then the rotating handle is adjusted to clamp the cable surface with a clamping plate. Simultaneously, a protective pad is laid on the surface of the clamping plate, which not only increases the friction between the clamping plate and the cable but also prevents damage to the cable surface due to clamping, thereby maximizing the prevention of cable joint protection failure caused by the connector or cable falling off or slipping. By setting a connecting groove, a mating plate, and a locking groove inside the plug cavity, when connecting the plug tube and the connecting pipe, the connecting locking block is first mated with the connecting groove and pressed to allow it to enter the sliding groove. Then, it is rotated until the connecting locking block engages and is fixedly connected, thus completing the connection between the plug tube and the connecting pipe. This provides a convenient and quick operation for the operator. Attached Figure Description
