背景技术Background technique

随着信息技术的高速发展，数据传输速率越来越高。高速连接器正向更高的速率，更高的密度发展。其中，背板连接器作为高速连接器的重要一员，其应用场景不断被拓展，如常规的印制板与印制板连接(背板)，印制板与印制板垂直连接(正交背板)，印制板或线缆与线缆连接(线背板)……相应这些新应用场景对背板连接器的强度、稳固性与可靠性提出了更加苛刻的要求。With the rapid development of information technology, the data transmission rate is getting higher and higher. High-speed connectors are developing towards higher speeds and higher densities. Among them, the backplane connector is an important member of the high-speed connector, and its application scenarios are constantly being expanded, such as the conventional printed board and printed board connection (backplane), the vertical connection between printed boards and printed boards (orthogonal Backplane), printed board or cable and cable connection (line backplane)... Correspondingly, these new application scenarios put forward more stringent requirements on the strength, stability and reliability of backplane connectors.

相关技术的背板连接器，端子组件为薄片体并列式拼接结构，并在该拼接结构上加装诸如盖板、底板等零件或在此基础上热熔或灌胶实现连接器的稳固。相关技术常采用热熔铆接或灌胶粘接的方式增加背板连接器稳固和可靠性，但热熔工艺不好控制，存在危险性，且需新增设备，效率低，成本高；灌胶工艺较成熟，但也存在效率低，成本高，胶模高温易失效等问题。In the backplane connector of the related art, the terminal assembly is a parallel splicing structure of thin slices, and parts such as a cover plate and a bottom plate are added to the splicing structure, or the connector is stabilized by hot melting or glue pouring. Related technologies often use hot-melt riveting or gluing to increase the stability and reliability of the backplane connector, but the hot-melt process is not easy to control, there is danger, and new equipment is required, with low efficiency and high cost; gluing The process is relatively mature, but there are also problems such as low efficiency, high cost, and easy failure of the plastic mold at high temperature.
