  • Patent number: 11621517
    Abstract: A connecting apparatus comprising a holding member and a conductive member. The holding member has holding portions. The conductive member has a plurality of held portions, a plurality of contact portions, a plurality of extending portions and a plurality of coupling portions. Each of the extending portions extends rearward in a front-rear direction from one of the held portions and protrudes rearward in the front-rear direction beyond the holding portion. The extending portions are positioned apart from each other in a right-left direction. The coupling portions are positioned apart from each other in the right-left direction. The coupling portions are positioned rearward of the extending portions in the front-rear direction. Each of the coupling portions couples two of the extending portions with each other. Two of the held portions, which are adjacent to each other in the right-left direction, are coupled with the two extending portions, respectively.

  • Patent number: 11362453
    Abstract: A first housing of a first connector has a first end wall which is located downward of a first accommodation portion in an up-down direction. When viewed from beneath along the up-down direction, the first end wall hides, in part, a first contact located in the first accommodation portion. A second housing has a second end wall which is located upward of a second accommodation portion in the up-down direction. When viewed from above along the up-down direction, the second end wall hides a second contact located in the second accommodation portion. The first end wall prevents a finger of an operator from coming into contact with the first contact, and the second end wall prevents the finger of the operator from coming into contact with the second contact.

  • Patent number: 11063386
    Abstract: A connector is provided with terminals, stoppers, and a socket insulator. The stoppers are attached to the respective terminals and are housed together with the terminals in the housing parts of the socket insulator. The stoppers are provided with parts to be locked, and lock spring parts that support the parts to be locked. Locking parts and operation parts are formed on the socket insulator. When the stoppers are housed in the housing parts, the locking parts are located rearward of the parts to be locked, and the locking parts restrict rearward movement of the stoppers. The operation parts can be operated in a prescribed direction that intersects the longitudinal direction. When operated, the operation parts cause the parts to be locked to move in the prescribed direction, and the restriction applied by the locking parts to the parts to be locked in released.

  • Patent number: 9787023
    Abstract: A connector is mateable with a mating connector along a front-rear direction. The mating connector has a mating lock portion. The connector comprises a housing and a contact. The housing has an upper wall and a lower wall. The housing forms a receiving portion. The receiving portion receives the mating connector when the connector and the mating connector are mated with each other. The contact is held by the housing. The contact protrudes in the receiving portion. The receiving portion is positioned between the upper wall and the lower wall in an up-down direction perpendicular to the front-rear direction. An inner surface of the upper wall is provided with a lock portion and a protrusion portion. When the connector and the mating connector are mated with each other, the lock portion locks the mating lock portion to lock a mating of the connector with the mating connector.
