20090253297CONNECTOR FOR ON-BOARD MOUNTING - The connector for on-board mounting includes a housing body having multiple contacts, metal locking engagement members each having a locking portion to be engaged with a locked engagement member provided to a cable-side connector for a purpose of locking a connection between connectors and being fixed to the housing body and a metal outer shell member covering a side wall of a front portion of the housing body and provided with opening portions through which the locking engagement members pass. The opening portion of the outer shell member is provided such that an edge thereof which faces the opening portion and the locking engagement member are brought into contact with each other and the locking engagement members and the outer shell member are provided with board-connecting posts on rear portions to be disposed on a board.10-08-2009
20090258529CONNECTOR - A connector which makes it possible to prevent contacts from being removed without increasing press-in force of the contacts. A crank-shaped portion or protruding portion is formed, as a retaining portion, on an linking portion which links a contact portion and a connection portion of each contact. A housing for holding a plurality of the contacts is comprised of a front housing in which contact-side portions of the contacts are disposed, and a rear housing in which connection-side portions of the same are disposed. When the front housing and the rear housing are assembled, the crank-shaped portion and the protruding portions are brought into abutment with the rear housing.10-15-2009
20100112846Connector of a simple structure having a locking mechanism - A transceiver connector adapted to be connected to a mating connector having a fitting hole and a latch. A metal hood serving as a housing is configured to be insertable into the fitting hole in an inserting direction. The transceiver connector includes a lever formed from a single metal plate and slidable with respect to the housing in the inserting direction and a detaching direction opposite to the inserting direction. The housing has a locking stepped portion adapted to engage the latch in the detaching direction. The lever has an inclined surface and a latch driving convex portion serving as an engagement releasing portion adapted to release engagement between the latch and the locking stepped portion by sliding of the lever, and a support piece continuous from the latch driving convex portion, folded back, and supported by the housing.05-06-2010
