The utility model provides a sensor in-mold secondary injection molding contact pin structure, which comprises a plurality of groups of contact pins, every two adjacent groups of contact pins are fixedly connected through a connecting rib to form a contact pin row, and the contact pin row is connected in a fixing piece in an injection molding manner and then forms a contact pin assembly through a connecting rib cut-off structure. And the pin assembly is connected in the shell in an injection molding manner to form the plug assembly. According to the utility model, the problem that the positions of the contact pins are easy to deviate when a plurality of metal contact pins are subjected to secondary injection molding in a traditional mode is solved. 本实用新型提供一种传感器模内二次注塑插针结构，包括若干组插针，每相邻的两组插针之间均通过连接筋固定连接形成插针排，所述的插针排注塑连接在固定件中后通过连接筋截断结构形成插针组件，所述的插针组件注塑连接在外壳中形成插头组件。本实用新型解决了传统方式在对多根金属插针进行二次注塑成型时，插针位置易发生偏移的问题。
