Abstract: A connector is mateable with a mating connector along an upper-lower direction (Z-direction). The connector comprises a housing and a terminal. The housing has a holding portion and an upstanding portion which are apart from each other in a width direction (Y-direction). The upstanding portion has a stop portion. The terminal has a held portion held by the holding portion and a spring portion extending from the held portion. The spring portion has a base portion and an upward extending portion extending upward from the base portion. The upward extending portion has a facing portion which faces the upstanding portion in the width direction. The facing portion has a stopped portion. Under a mated state where the connector and the mating connector are mated with each other, the stop portion is located above the stopped portion and faces the stopped portion in the upper-lower direction.

Abstract: A wire connection portion of a terminal has a first part and a second part. The first part has two first sidewall portions and a first coupling portion coupling them. The first sidewall portions are located apart from each other in a lateral direction. The second part has two second sidewall portions and a second coupling portion coupling them. The second sidewall portions are located apart from each other and outside the first sidewall portions, respectively, in the lateral direction. The first coupling portion is located apart from the second coupling portion in an up-down direction. The first sidewall portions are provided with contact portions, respectively, to be brought into contact with an electrical wire. When the electrical wire is connected to the terminal, the contact portions sandwich the electrical wire in the lateral direction. The contact portions may be rounded to press on sides of a bare wire placed in the device.

Abstract: A dummy pin includes a pin main body that is to be inserted into the at least one terminal insertion port and is formed by molding resin, the pin main body having: a waterproof portion having a cylindrical seal surface that makes tight contact with an inner surface of the at least one seal hole by elastically compressing a part of the two or more lip portions of the waterproof member; and a falling-off prevention portion having one or more concave portions that are partially recessed from the seal surface toward the central axis and that a remaining lip portion of the two or more lip portions of the waterproof member enters, the seal surface forming a continuous surface over an entire circumferential direction of the waterproof portion.

The spring portion has a base portion and an upward extending portion extending upward from the base portion. The upward extending portion has a facing portion which faces the upstanding portion in the width direction. The facing portion has a stopped portion. Under a mated state where the connector and the mating connector are mated with each other, the stop portion is located above the stopped portion and faces the stopped portion in the upper-lower direction.

Abstract: A connector is mountable on an object in an upper-lower direction and mateable with a mating connector along the upper-lower direction. The connector comprises a housing and an additional member held by the housing. The housing has a receiving portion for receiving the mating connector. The additional member has a fixed portion fixed to an object, a base portion which extends upward from the fixed portion and is located outside the receiving portion in a lateral direction, an armor portion extending inward from the base portion in the lateral direction, a spring portion extending from the base portion and a projection which is supported by the spring portion and projects inward in the lateral direction. The extending of the spring portion from the base portion starts at a starting portion which is nearer to the fixed portion than to the innermost part of the armor portion.

Abstract: A connector is mountable on an object in an up-down direction and mateable with a mating connector along the up-down direction. The mating connector comprises four locked portions. The connector comprises two additional members. Each of the additional members comprises two regulation mechanisms. Each of the regulation mechanisms comprises a spring portion, an operation portion, a first regulating portion, and a second regulating portion. The spring portion has a lock portion. The operation portion has a first regulated portion. One of the spring portion and the operation portion is provided with a second regulated portion. An upward movement of the lock portion is regulated when the first regulated portion is moved upward in the up-down direction to abut against the first regulating portion.

Abstract: A connector is mountable on a circuit board and mateable with a mating connector along a mating direction. The connector comprises a contact, a housing, an enclosing portion and a coupling portion. The housing holds the contact. The enclosing portion encloses an outer circumference of the housing in a plane perpendicular to the mating direction. The coupling portion directly or indirectly couples the enclosing portion with the housing so as to allow the enclosing portion to move along the mating direction relative to the housing.

Abstract: A connector comprises a housing and a terminal. The housing has a terminal accommodation portion and a bottom portion. The terminal accommodation portion opens upward in an up-down direction. The bottom portion is positioned under the terminal accommodation portion. The terminal has a base portion, a spring portion and a contact portion. The base portion is embedded in and held by the bottom portion. The spring portion extends upward from the base portion and is accommodated in the terminal accommodation portion. The contact portion is supported by the spring portion. The base portion is enclosed by the bottom portion in a predetermined plane perpendicular to the up-down direction and is in contact with the bottom portion with no gap in the predetermined plane. When the connector is seen from below, the base portion is partially visible, but the terminal accommodation portion is invisible.

Abstract: Provided is a connector having a locking mechanism that can ensure both the joining strength between a housing and a locking portion and the locking strength and that can cope with pitch narrowing and miniaturization. A plug connector comprises a plug-side housing, plug-side contacts provided to the plug-side housing and adapted to be electrically connected to a receptacle connector, and plug-side locking portions provided to the plug-side housing and adapted to maintain a connected state of the plug connector and the receptacle connector. The plug-side locking portions each comprise a locking plate having a flat plate-like shape and provided so that the normal direction of the plane of the flat plate is oriented in a locking direction with the receptacle connector, and retaining portions provided to the locking plate and formed so as to be integrated with the plug-side housing.

Abstract: In a board-to-board connector assembly, a plug-side power contact includes a first flat surface portion having a plate-like shape, a second flat surface portion having a plate-like shape and being opposed to a first part of the first flat surface portion and a power-contact-side connection portion connecting the first and second flat surface portions to each other. The first flat surface portion has the first part facing in parallel to the second flat surface portion and a second part or an upper end portion other than the first part. The first part includes a thinned portion having a shape recessed more deeply than a surface of the upper end portion and having a smaller thickness along the third direction than a thickness of the upper end portion.
