Rapid conductor locking structure

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 ...

[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). 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 to carry out, 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 used in electronic products, and it is easy to operate, and a good airtightness can be formed between the terminal and the wire Sexual contact, but this kind of connection is generally not used in large current transmission

Considering the convenience of operation, wire type and specification, assembly cost and scope of use, these termination methods have different degrees of disadvantages. For example, for different types of wires, the structure and size of metal terminals will change, and special Tooling for connecting wires to metal terminals

With the development of technology, the squirrel-cage reed locking wire structure has been widely used due to its reliability and convenience. However, when the wire is thick and works for a long time, there will be hidden dangers such as wire loosening.
