Abstract: Automotive diagnostic interface plug-in is a necessary plug-in in automotive wiring harness, that is, different brands of diagnostic interface plug-in have the same model, but due to the different vehicle structure of different models, the location of diagnostic interface on the vehicle is different. This paper studies the fixed structure form of automobile diagnosis interface. By using the fixed structure form of diagnosis interface designed on the electrical box body, the fixed position of diagnosis interface plug-in can be standardized and unified while the diagnosis interface plug-in can be fixed reliably.

摘要： 汽车诊断接口插件是汽车线束中的必备插件，即不同品牌的诊断接口插件型号一样，但受限于不同车型整 车构造的不同，诊断接口布置于整车上的位置各不相同。文章研究了汽车诊断接口的固定结构形式，通过采用在电 器盒本体上设计诊断接口固定结构的形式，满足诊断接口插件可靠固定的同时，实现了诊断接口固定位置的规范统 一。
