Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, specifically a robust FPC connector. Background Technology

[0002] FPC is an abbreviation for Flexible Printed Circuit Board, a type of printed circuit board made of flexible materials. FPC connectors are mainly used to connect LCD displays and driver circuits, and are widely used in digital communication products, portable electronic devices, computer peripherals, and automotive electronics.

[0003] FPC connectors, also known as flexible flat cable connectors, are a new type of data cable made using PET insulation material and extremely thin tin-plated flat copper wire. These FPC connectors are thin, small in size, easy to connect and disassemble, and have good electromagnetic shielding.

[0004] Since FPC connectors are mostly used for connections between drive circuits and displays, their small size and ease of disassembly result in poor stability in drive circuits, and their dense pin count also increases the difficulty of the soldering process. Therefore, we propose a stable FPC connector. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a robust FPC connector, which has the following advantages:

[0016] 1. This robust FPC connector, when soldering the connecting board to the drive circuit board, first inserts the positioning block on the connecting board into the positioning slot on the drive circuit board. At this time, the connecting board is positioned at the required soldering location on the drive circuit board, which helps to prevent misalignment of the FPC connector during soldering.

[0017] 2. After soldering, this stable FPC connector is installed by inserting the second clip along the connection slot into the FPC board and pushing the connector lock inward to fix the FPC. At this time, the roller is engaged with the position of the limiting block set on the drive circuit board. The limiting plate is then inserted into the position of the limiting slot on the connection board. The limiting slot in the partition connected to the limiting plate will engage with the second positioning plate on the connector lock. Finally, the first clip is engaged between the tail end of the limiting plate and the drive circuit board. This improves the connection stability of the FPC connector in the drive circuit and also improves the connection stability between the FPC connector and the FPC. Attached Figure Description
