Description

Technical Field

[0001] The present invention relates to a connector, in particular to a high-speed backplane connector with a locking function. Background Art

[0002] The power connector is a bridge connecting the power output end and the receiving end. Therefore, the current output of the power connector is crucial. The factors affecting the current transmission of the power connector include the body impedance of the conductor conduction material, the compression impedance, and the heat dissipation system of air convection.

[0003] In the development of current connectors, after the male and female ends of the electrical connector are inserted into each other, the direct locking of the connector plays a role in current transmission and safety. In traditional electrical connectors, it is rather troublesome to use screw locking between the male and female products, which takes a long time and is complex in operation. In the case of use in a small space, it is impossible to lock by hand or with tools. There is also a conventional connector that uses clamping on both sides. In this case, there is also a situation where the small space cannot accommodate a human hand for operation. Therefore, a structure for locking and unlocking at the connection of the connector is needed.

[0004] Patent CN102522659B discloses a connector locking structure, which mainly consists of two parts: a slider component part and a reed component part; the slider component part is installed on the second plastic base, and the reed component part is installed on the first plastic base; the slider component part includes a slider; two slider rounded base parts extending forward are provided at the front end of the slider, and a rounded support part is provided at the front end of the slider rounded base part; the reed component part includes a reed, which is mainly composed of a connecting part and a bending elastic part, and a locking hole is provided on the bending elastic part, and the locking hole cooperates with the lock catch of the second plastic base to lock the first plastic base and the second plastic base; the rounded base part and the rounded support part are superimposed under the reed in the locked state of the first plastic base and the second plastic base. The locking structure of this patent is an independent connector. When in use, not only are there many parts, but also the installation and disassembly are extremely inconvenient.
