Cable quick-connection plug and socket connection structure

Abstract

The invention relates to a cable quick-connection plug and socket connection structure. The cable quick-connection plug and socket connection structure comprises a plug body and a socket body, whereinthe plug body and the socket body are detachably connected with each other; the cable quick-connection plug and socket connection structure further comprises a quick-connection sleeve, a locking component with an external thread and a locking spring; a mounting hole is formed in the quick-connection sleeve; the periphery of the quick-connection sleeve is provided with a radial locking protrusion;a quick-connecting sleeve hole into which the quick-connecting sleeve extends is formed in the socket body; a radial extending groove into which the radial locking protrusion can extend is formed inthe inner wall of the quick-connecting sleeve hole; a threaded locking groove matched with the radial locking protrusion is formed in the axial inner side of the extending groove; the locking spring sleeves the locking component; and the locking component is arranged in the mounting hole and is in threaded connection with the plug body. The cable quick-connection plug and socket connection structure of the invention has the advantages of strong locking force, high safety and high reliability, and will not slip even if being subjected to external forces such as pulling and vibration.

Description

technical field [0001] The invention relates to a connection structure between a cable quick-plug joint and a socket, and belongs to the field of electrical equipment design and manufacture. Background technique [0002] Cables are generally used for the transmission of high voltage and high current. In order to reduce the loss of transmission energy, the method of increasing the cable section and reducing the resistance is often used. However, due to the large cross-sectional area of ​​the cables, it is inconvenient for the connection between the cables, and the connection between the cables must use special joints and sockets. Moreover, the joint and socket must meet the requirements for quick plug-in connection. [0003] The traditional cable quick-connect plug and socket connection usually adopts a radial protrusion on the cable quick-connect plug, and is directly screwed and connected in the hole of the socket. However, since this connection is a rigid connection, in t...

Problems solved by technology

[0003] The traditional cable quick-connect plug and socket connection usually adopts a radial protrusion on the cable quick-connect plug, and is directly screwed and connected in the hole of the socket. However, since this connection is a rigid connection, in the actual working environment, the cable It will often be subjected to external forces such as pulling vibrations. As long as the plug and socket are slightly loose, the locking force will drop rapidly, causing the plug and socket to be separated and loosened, resulting in an increase in the contact resistance of the conductive end surfaces of the plug and socket. When the current When it is too large, the temperature of the plug will rise too high, and the connector will be burned out, causing losses. The plug must be replaced, which will increase the cost of use.
