Cascade FPC connector

Abstract

The invention relates to a cascade FPC connector. The FPC connector comprises a shell and an FPC terminal assembly, the shell comprises a multi-layer cascade structure composed of a substrate, one ormore layers of intermediate plates and a top plate, two adjacent layers of the shell are detachably buckled and fixed, the top plate and the substrate are detachably buckled and fixed, and a positioning area and a terminal plugging channel are arranged between two adjacent layers. The FPC terminal assembly comprises an FPC soft board and a puncture type terminal connected to the end of the FPC soft board, the puncture type terminal can be installed in the insertion channel in the horizontal direction, and after the two adjacent layers of the shell and the top board and the substrate are buckled and fixed, the FPC terminal is fixed and limited by the positioning area. Compared with the prior art, due to the design of the layered vertical stacking structure, the self weight and the self space occupation ratio are reduced, the vertical design space is compressed, meanwhile, a stable compression structure is formed through the vertical compression structure, and the connection stability isremarkably improved.

Description

Technical field [0001] The invention relates to the field of connectors, in particular to a cascaded FPC connector. Background technique [0002] With the rapid increase in electronic equipment for automobiles and electrical appliances, the usage of connectors for each component has increased from dozens to hundreds, and miniature connectors have gradually come into our sight. Miniature connectors have smaller size, thinner wall thickness, and lighter weight, which have become an important part of the lightweight of the wire harness. [0003] In particular, the internal connectors of the battery pack are now more and more miniaturized and light-weight designs. The cost and self-weight problems of the wires used to restrict the development of the internal connectors of the battery pack to miniaturization and light weight. However, the current line connection All are implemented with FPC boards to control the cost and weight of the product. [0004] FPC connectors on the market now g...

AI Technical Summary

Problems solved by technology

[0004] FPC connectors on the market now generally have the following problems. 1. The current FPC connector itself has a relatively large volume. In the face of the need for more FPC terminals to be connected at the same time, the connector needs to expand the width to build more sockets. However, this will significantly increase the volume of the overall structure; 2. Most of the FPC connectors of existing products are connector shell components assembled in advance. When multiple FPC terminals need to be plugged and assembled at the same time, it needs more The large insertion force is inserted one by one, and the FPC soft board is easy to bend, which leads to low assembly efficiency; 3. FPC and terminal crimping positions are prone to breakage and other abnormalities, especially in the use scene with vibration, which will significantly reduce connection stability
