Description

Technical Field

[0001] The utility model relates to a connector assembly, in particular to a connector assembly with extremely simple structure. Background Art

[0002] The flexible flat cable (FFC) or flexible printed circuit cable developed in the existing industry can be mass-produced automatically, and is very suitable for the control of high-frequency signal transmission. The wire cores of the flexible flat cable are arranged neatly, with large transmission capacity, flat structure, small volume, flexibility, etc., and can be flexibly applied to various electronic products as a conductor cable for power supply and data transmission.

[0003] However, as is well known in the industry, when using a multi-layer printed circuit board (PCB) as the connector tongue plate in the prior art, after the connector tongue plate is fabricated, the contact part of the flexible flat cable is welded to the welding parts of multiple conductors provided on the multi-layer PCB. However, as long as the high-frequency transmission of electronic signals passes through a medium transformation (such as having one more solder joint or one more transmission component in the connector), the signal loss and attenuation will surely increase. Therefore, the connector assembly of the prior art not only has numerous components, but also increases the difficulty of achieving high reliability. Therefore, the design of a connector assembly with extremely simple, compact structure, simple manufacturing process and high reliability is the top priority urgently needed in the industry. Therefore, this is an important issue that the utility model urgently wants to solve here.

[0004] Therefore, with the trend that the design of the connector assembly towards being thin, light, short and small, and having a suitable price is bound to become the mainstream, and based on the premise that the requirements for the front-opening transmission specification are getting higher and higher, it is indeed necessary to propose a connector assembly with extremely simple, compact structure, simple manufacturing process and high reliability. This is an important issue that the utility model urgently wants to solve here. Summary of the Utility Model
