Background technique

With the popularization of SMT (Surface Mount Technology, surface mount technology) technology, the application of surface mount connectors has become more and more extensive, and various types of PCBs have corresponding surface mount connectors. From the through-hole (T/H) soldering process to the surface-mount (SMT) soldering process, the terminal arrangement pitch (Pitch) of the connector can be reduced from 1.27mm to 1.0mm, and gradually reduced to 0.8mm and 0.5mm , and the application of the SMT process allows electronic components to be soldered on both sides of the PCB, which greatly increases the component density on the PCB. Various types of consumer electronic products using connectors now have integrated miniaturization, thinning and high performance, which has prompted the corresponding connectors to be shortened and the connecting parts to be narrower. At present, among the connector products of floating BTB, various companies have begun to mass-produce 0.5mm pitch connector products.

However, in the existing process of designing FFC/FPC, the requirement of arrangement spacing cannot be met, the customer's operation is inconvenient, and the FFC/FPC is easily separated from the main body due to the influence of external force, resulting in unstable contact signals and other problems.

The beneficial effects achieved by the present invention: the present invention is more convenient compared to the traditional locking structure. When inserting the FFC/FPC, the FFC/FPC pushes up the cover along the guide on the cover. Hold both ends of the cover to realize the automatic locking of the cover. At this time, the FFC/FPC is locked by the hook and is not affected by external force. It can be stably connected to the signal terminal and the ground terminal. Press and hold the cover and tilt it upwards, the cover will be lifted, the hook will be higher than the hollow in the middle, and the FFC/FPC will no longer be locked. At this time, the FFC/FPC can be easily pulled out.
