In the related art, there has been proposed an engaging means that engages with a wiring board-like member and is provided with locking means involved in preventing undesired removal of the wiring board-like member from the housing (see, for example, Patent Document 1). .) Further, the connector belonging to the second type having a housing, having a plurality of contacts, and further having a conductive shell but not having an actuator that can be rotated with respect to the housing, as described above. Also proposed is a device that is provided with a locking means that engages with a wiring plate member inserted into the housing through the insertion portion and prevents undesired removal of the wiring plate member from the housing. (For example, refer to Patent Document 2 and Patent Document 3).

  In the connector device (flexible substrate connector) disclosed in Patent Document 1, a pair of reinforcing metal fittings (20) are attached to both side walls (5) in the arrangement direction of the plurality of contacts (6) in the housing (2). Each reinforcing bracket is in contact with the wiring board member (flexible substrate (30)) inserted through the insertion part (opening (3)) into the housing and pushes it up to the wiring board member. Locking means (elastic supporting piece) that applies a pressing force or engages with an engaging portion (engagement hole or notch (32)) of a wiring board member inserted into the housing through the insertion portion (25)) is formed. When the actuator (pressurizing member (12)) provided so as to be rotatable with respect to the housing is rotated from a position where it is raised relative to the housing to a position where it is depressed relative to the housing, it is inserted into the housing. The printed wiring board member is pressed by the actuator toward the locking means from the side opposite to the locking means formed on the reinforcing metal fitting.

Originally, when the wiring plate-like member is inserted into the housing through the insertion portion, the locking portion formed on the movable locking means engages with the engaging portion of the wiring plate-like member to engage the wiring plate-like member. Stop. Thereby, undesired removal of the wiring plate member inserted into the housing from the housing is prevented.

  Thereafter, the movable conductive shell moves in the insertion direction of the wiring plate member relative to the housing against the biasing force of the elastic member biasing it in the direction opposite to the insertion direction of the wiring plate member relative to the housing. When it is slid in the direction along, the tapered portion formed in the through hole in the sliding movable conductive shell engages with the ejection locking piece formed on the movable locking means, and presses the ejection locking piece. Then, the movable locking means is moved in a direction to release the engaged state of the locking portion formed on the wiring plate-like member with the engaging portion. As a result, the locking portion formed on the movable locking means is released from the engagement with the engaging portion of the wiring plate-like member, and the wiring plate-like member inserted into the housing can be removed from the housing. It is burned.

And an elastic arm portion (22) for supporting, and the other end portion of the unlocking means is engaged with the elastic arm portion.

  Then, when the wiring plate member is inserted into the housing through the plate member insertion portion, the locking portion in the locking means engages with the engaging portion in the wiring plate member, and the wiring plate member is locked. Thereby, undesired removal of the wiring plate member inserted into the housing from the housing is prevented.

  Thereafter, when a pressing operation for pressing one end of the unlocking means protruding outside the conductive shell toward the inside of the housing is performed, the other end of the unlocking means becomes an elastic arm portion in the locking means. And the elastic arm portion is displaced, and accordingly, the engaging portion supported by the elastic arm portion is moved to a position where the engagement with the engaging portion in the wiring board member is released. It can be displaced. As a result, the locking portion formed on the movable locking means is released from the engagement with the engaging portion of the wiring plate-like member, and the wiring plate-like member inserted into the housing can be removed from the housing. It is burned.

JP 2003-100370 A (pages 3 to 4, FIGS. 1 to 10) JP 2009-231069 (page 3-4, FIGS. 1-5) Japanese Patent Laying-Open No. 2011-40246 (pages 11-16, FIGS. 5-11, 15-17)
