Abstract: A board-to-board connector includes a first connector and a second connector. The first connector includes a first shell which has four side wall portions arranged like a square frame. The second connector includes a second shell which has four side wall portions arranged like a square frame. In a state in which the first and second connectors are connected to each other, the second shell is fit inside the first shell. For a pair consisting of one arbitrarily selected side wall portion of the four side wall portions of the first shell and one side wall portion, corresponding to the one selected side wall portion, of the four side wall portions of the second shell, one side wall portions of the pair has a protruding portion which extends linearly along the one side wall portion, and the other side wall portion of the pair does not have the protruding portion.

Abstract: A plug auxiliary fitting includes a plug side-wall facing portion facing a side surface of a plug housing. The plug side-wall facing portion includes a plug electrical connecting portion capable of coming into electrical contact with a receptacle auxiliary fitting, and a plug mating lock portion that cooperates with the receptacle auxiliary fitting to prevent a mating state between a plug connector and a receptacle connector from being released. The plug electrical connecting portion and the plug mating lock portion are, in a direction parallel to a plug-connector mounting surface of a plug-side board, adjacent to each other with a notch opened toward the plug-connector mounting surface of the plug-side board interposed therebetween. The plug mating lock portion is provided with a soldering portion solderable to the plug-connector mounting surface of the plug-side board.

Abstract: A connector assembly comprises a first connector and a second connector. The first connector comprises a first inner structure and a first housing. The first inner structure comprises a first connector main body. The second connector comprises a second inner structure and a second housing. The second inner structure comprises a second connector main body. The second connector main body comprises a plurality of second terminals, a second holding member and a second shell. The second connector main body is mated with the first connector main body under a mated state where the first connector and the second connector are mated with each other. A distance from a front end of the first housing to a rear end of the second shell is shorter than a distance from a rear end of the second housing to the rear end of the second shell in a front-rear direction under the mated state.

Abstract: A connector includes contacts, a mid-plate and a housing, each contact having a contact portion at a front end portion and having a length corresponding to an effective connection length along a fitting direction, an exposed portion adjacent to a rear end of the contact portion and exposed from the housing, a connecting portion at a rear end portion, and a holding portion between the exposed portion and the connecting portion and at least partially embedded in the housing, the contact portion of each contact being disposed away from the mid-plate by a predetermined distance, each of a plurality of pairs of contacts having a separation portion separated from the mid-plate by a separation distance longer than the predetermined distance, the separation portion including the exposed portion and a part of the holding portion adjacent to a rear end of the exposed portion in the fitting direction.

Abstract: A connector inspection apparatus includes a first main body part, a terminal, and a connector module. The connector module includes a second main body part, a contact part, and a connector. The connector is a counterpart connector of a connector to be inspected. In a state in which the connector module is attached to the first main body part, the terminal and the contact part are in contact with each other and the terminal is electrically connected with a contact pin of the connector via the contact part.

Abstract: A connector has first group terminals and second group terminals. Each of the first group terminals is provided with one first contact portion and at least one first wire connection portion. The first contact portion is located forward of the first wire connection portion. Each of the second group terminals is provided with one second contact portion and one second wire connection portion. The second contact portion is located forward of the second wire connection portion. The first contact portion and the second contact portion are arranged in a pitch direction. In the pitch direction, between adjacent two of the first contact portions, at least two of the second contact portions are located. The first wire connection portion is located at a position different from a position of the second wire connection portion in the front-rear direction and in the up-down direction.

Abstract: A connector is mateable with a mating connector along a predetermined direction. The mating connector comprises a mating lock portion. The connector comprises at least a connector main. The connector main comprises a holding member, a plurality of contacts and two lock portions. The contacts are held by the holding member. Each of the lock portions has a held portion and a spring portion. The held portion is held by the holding member. The spring portion is resiliently deformable. The spring portion has a locking protrusion and a resilient supporting portion. The locking protrusion and the mating lock portion lock a mated state where the connector and the mating connector are mated with each other. The connector main has a space which is positioned inward in a first direction beyond the spring portion. The space allows resilient deformation of the spring portion.

Abstract: Each of contact portion rows 310 and 320 includes an outer contact portion 212 and an inner contact portion 216 forming a differential pair. In a Y-direction, the outer contact portion 212 and the inner contact portion 216 of the contact portion row 310 are located at same positions as those of the other contact portion row 320, respectively. A main portion 430 of a mid-plate 400 is located between the contact portion rows 310 and 320 in a Z-direction. Between the main portion 430 and each lock portion 450, a space 500 is provided to allow resilient deformation of a spring portion 460. A side edge 432 of the main portion 430 that oriented outward in the Y-direction is located between an inner edge 212A of the outer contact portion 212 and the lock portion 450 in the Y-direction.

Abstract: A connector assembly comprises a first connector and a second connector. The first connector comprises a first inner structure and a first housing. The first inner structure comprises a first connector main body. The second connector comprises a second inner structure and a second housing. The second inner structure comprises a second connector main body. The second connector main body comprises a plurality of second terminals, a second holding member and a second shell. The second connector main body is mated with the first connector main body under a mated state where the first connector and the second connector are mated with each other. A distance from a front end of the first housing to a rear end of the second shell is shorter than a distance from a rear end of the second housing to the rear end of the second shell in a front-rear direction under the mated state.
