Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a rear-locking circuit board connector. Background Art

[0002] Connectors are also often called circuit connectors and electronic connectors. They are widely used in various electrical circuits to connect or disconnect current or signals. This connection may be temporary and easy to plug and unplug at any time, or it may be a permanent node between electrical equipment or wires.

[0003] An electronic connector is a motor system that bridges two conductors in a loop so that current or signals can flow from one conductor to another. The components used to complete the electrical connection between circuits or electronic machines are called connectors.

[0004] Similar to the above application, the existing connector uses a rear lock to fix the FPC connecting line in place to prevent the FPC from loosening and falling and affecting the operation of the circuit board. However, there is a certain gap between the connector and the rear lock, which makes it easy for dust in the air to sink into the inside of the seat body, causing plug-in wear on the terminals and the FPC connecting line. At the same time, the FPC connecting line is composed of a wire tape and a plug-in. When the plug-in enters the connector, the connection between the plug-in and the wire tape is easily bent, which will cause poor contact of the FPC connecting line over a long period of time.
