Description

Technical Field

[0001] The utility model belongs to the technical field of cable accessory connectors, in particular to a self-locking cable accessory connector. Background Art

[0002] Cable accessory connector is a device that connects the two ends of the cable body, enabling the cable to be connected to other electrical equipment (such as transformers, switchgear, etc.) or cables to each other.

[0003] Traditional cable accessory joints usually install the connector terminal on the cable first, and then connect the connector terminal to the cable or other electrical equipment. When two cables are connected through a connector, it is usually necessary to put screws on the two connector terminals and require workers to use tools to turn the screws to fix the cable connection. This method is complicated to operate and inefficient. Moreover, when inserting the screws, the cable will swing, making it difficult to align the two connectors and difficult to dock them. Therefore, we propose a self-locking cable accessory joint. Utility Model Content

By setting a docking component, specifically when cable one and cable two need to be connected to each other, cable two is directly inserted into the docking groove in the docking block, and the locking block will be reset under the action of the spring elasticity. At this time, the locking block will clamp and fix the connector terminal to achieve a self-locking function. Then the handle is turned clockwise to move the threaded rod downward so that the locking block is in close contact with the connector terminal, thereby improving the fixing effect. This method can quickly complete the docking, and the operation is simple and convenient. It solves the problem that when traditional cables are connected using accessory connectors, the staff needs to use tools to turn the screws to fix the cable connection, the operation is complicated, and it is difficult to align the two connectors, and it is not easy to dock.
