Patent number: 9490564Abstract: A bevel portion extends from a front end of a plate-like electrical contact of the terminals to a lengthwise intermediate portion of the electrical contact, the bevel portion residing at an intersection of a width surface of the electrical contact with a thickness surface of the electrical contact. A step portion resides at an end of the bevel portion at the lengthwise intermediate portion of the electrical contact, the thickness surface extending in the thickness direction having one portion with reduced width defined by the bevel portion in the thickness direction. The other portion of the thickness surface continuing to an end of the step portion has an increased width in the thickness direction to define a press-fit portion. The electrical contact is inserted in a hole of a housing to the extent defined by the step portion and thereby provisionally locked with the press-fit portion press-fitted in the hole.Type: GrantFiled: March 21, 2012Date of Patent: November 8, 2016Assignee: Yazaki CorporationInventors: Kouichi Nakayama, Tsuyoshi Mizushima

Patent number: 9356398Abstract: A shield connector is for assembling of a connector housing and a shield shell acted by a small insertion force and locking the connector housing and the shield shell by a large holding force. A flexible lock arm having a projection projecting outwardly is arranged at an insulation connector housing. A locked member engaged with the projection is arranged at a shield shell in which the connector housing is inserted. When the projection is half locked with the locked member, the lock arm is prevented from bending to unlock. When the connector housing is inserted into the shield shell, the lock arm is bent and also the projection is press-fitted along an inner surface of the shield shell. A stopper facing and abutting on an inner surface along a bending direction of the lock arm is arranged at an outer surface of the connector housing.Type: GrantFiled: February 13, 2012Date of Patent: May 31, 2016Assignee: Yazaki CorporationInventors: Kouichi Nakayama, Tsuyoshi Mizushima
