  • Publication number: 20200127401
    Abstract: An ECU (1) includes a circuit board (10), a connector (20) fixed to the circuit board (10), and a resin portion (50) covering the circuit board (10) and the connector (20). The connector (20) includes a connector housing (21) having a terminal holding wall (22) that separates the internal space from the external space, and terminal fittings (41) extend through the terminal holding wall (22). The connector housing (21) includes a surrounding wall (27) disposed on the lateral surface of the terminal holding wall (22) to surround the terminal fittings (41). A potting material (28) is disposed inside the surrounding wall (27) and separates the terminal holding wall (22) from the resin portion (50). This can prevent a melted resin from entering a hood (24) through press fitting holes (23) at the time of forming the resin portion (50) by mold forming.

  • Patent number: 9431745
    Abstract: A connector includes a plurality of terminals, a housing, and a retainer. The housing includes terminal housing chambers and partition portions. Each of the terminal housing chambers accommodates therein each of the plurality of terminals. Each of the partition portions is provided between adjacent terminal housing chambers and partition the adjacent terminal housing chambers from each other. The retainer is attached to the housing. The retainer is configured to prevent each of the terminals from falling out and to move between a temporary locking position and a proper locking position. The retainer includes communication cut portions. While the retainer is moving between the proper locking position and the temporary locking position, each of the communication cut portions is kept in contact with its corresponding partition portion and cut off communication between the adjacent terminal housing chambers.
