Abstract

The invention discloses a rapid conductor locking structure comprising a metal terminal and a locking spring coil. The rapid lead locking structure is characterized in that the metal terminal is formed by connecting the front end and the rear end of a conductor plate with a butt joint and a tension disc, and the butt joint is formed by two contact plates connected in parallel; the tension disc isa pressing plate provided with a front convex hull and a rear convex hull, the locking spring coil is a snap spring of which an circular arc, an upper cantilever beam and a lower cantilever beam are connected in an equilateral triangle, the tension disc is sheathed with the locking spring coil, and the pressing plate is used for rapidly locking a conductor by the front convex part, the rear convex part and a conductor locking port. Compared with the prior art, the invention has the advantages of simple structure, capability of carrying out connection or disassembly and replacement on different specifications of conductors as required, no needs of special frocks, convenience for operation, enlarged conductor contact area, enhanced electricity bearing capability, rapidness and reliability of conductor connection, flexibility and wide application in the aspect of usage.

Description

technical field

[0001] The invention relates to the technical field of electrical connectors, in particular to a wire fast locking structure for connecting wires of different types to metal terminals. Background technique

[0002] At present, the commonly used terminal and wire connections mainly include several termination methods such as welding, crimping, wrapping and IDC (insulator displacement connection). Among them, the welding method is widely used due to its low cost and convenient use. Welding has certain requirements for operational skills, and false welding is prone to occur in production; the crimping method is easy to operate and reliable in connection, but the cost is relatively high, and special crimping tools are required, and this method is also more common; wrapping The method is to wind the wire around the end of the metal terminal, which is inconvenient to operate and has a small range of use; the insulator displacement (IDC) connection method is widely ...
