Description

Technical Field

[0001] The utility model belongs to the technical field of electrical components, and particularly relates to a double-row FFC cable connector. Background Art

[0002] With the rapid development of the automotive industry, the requirements of the industry and the market for the space occupation ratio and weight of wire harnesses are getting higher and higher. The traditional wire harnesses can no longer meet the above requirements, and FFC cables are more and more widely used in the automotive industry.

[0003] Most of the existing FFC cable connectors are single-row connectors. For the double-row connectors, some use the flip-cover type or press-type structure to fix the flexible cable, which requires a large space; some use the direct insertion method for fixation, and the protection and fixation effect on the FFC cable are insufficient, and it is easy to loosen under pulling. The connection methods of the above double-row connectors cannot ensure the connection stability and the information transmission stability. The existing double-row FFC cable connectors cannot meet the development needs of the industry in terms of the occupied space size and weight. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a double-row FFC cable connector with more stable transmission than the prior art.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is: a double-row FFC cable connector, including a first housing, a second housing, a first sheath, a second sheath, a first flexible cable and a second flexible cable.

[0012] By adopting the above solution, the two flexible cables 1 can be separated by the flange, and at the same time, the connection between the flexible cable 1 and the conductive terminal will not produce a large shake when the utility model is actually used, making the connection between the flexible cable 1 and the conductive terminal more stable.

[0013] As a further configuration of the present invention, the first fixing structure is at least two fixing blocks arranged on the step surface and fixing holes arranged on the first flexible flat cable for the fixing blocks to be embedded in.

[0014] By adopting the above solution, the fixing block and the fixing hole cooperate to keep the flexible flat cable 1 and the housing 1 relatively fixed, so that the flexible flat cable 1 and the conductive terminal are stably connected when the utility model is actually used.
