汽车线束与连接器的技术发展

本文介绍了最近行业中汽车线束和连接器的研究进展情况。汽车线束通过高强度0.13mm2电线、铝线及发泡护板技术来实现轻量化仍是目前重要的趋势之一。柔性化平面电路(FPC)及平面电缆(FFC)在部分特殊空间得到应用。高压线束的超声波焊接因成本低、可靠性好成为目前高压线束研究的热点之一。通过模块化可减少线束的长度。采用无线传输是汽车电器工程师追求的最终目标。汽车连接器则在增加触点、防弯针技术研究的同时向着小型化、高压化、高速化发展。高压连接器通过矩形端子降低加工成本的同时有集成化趋势。连接器的自动化装配很好地保证了连接器的安全性、稳定性,并提升了装配效率。

The Development of Automobile Harness and Connector

In this paper,the recent development of the automobile harness and connector are introduced.One development trendy of the harness technology is the light weight with the high strength 0.13mm² wire,Aluminum wire,and foaming back plate.The flexible printed circuit and or flexible flat cable are also applied in the special space.The ultrasonic welding of the high voltage harness has become the hot study recently due to the low cost.The length of the harness is reduced with the modularity harness.The wireless transmissionbecomes the final objectives of the engineers seeking.The multi contacting spot and pin bending-proof are studied for the terminal of the connector.In the meantime,the miniaturization,high voltage connector,and high speed connector become the studying hot.The rectangle terminals of the high voltage connector are the low cost.The integration of the high voltage connector is also studied.The safe and stably of the connector can be ensured by the automatic assembly of the connector.And the assembly efficiency of the connector is raised.
