  • Structure for connecting terminal to circuit substrate within case
    Patent number: 12048104
    Abstract: In a structure for connecting a terminal to a circuit substrate within a case, a resin holder to which a plurality of terminal members are insert bonded is insert bonded to a resin case member having a connector portion and configuring part of the case. Each terminal member has one end part connected to the circuit substrate housed in the case, another end part of the terminal member being disposed within the connector portion. The holder is insert bonded to the case member while leaving an exposure hole as a cavity. Formed in the case member is an open hole communicating with the exposure hole and opening on a housing chamber side. Accordingly, it is possible to prevent a short circuit due to moisture from occurring between the terminal members retained by the holder.
