Abstract: A connector comprises an insert-molded body. The insert-molded body comprises a holding member and a plurality of terminals. The terminals include at least one first terminal and at least one second terminal. The first terminal has a first mounted portion and a first main portion. The first mounted portion has a first carrier cut-off surface which is an end surface of the first mounted portion. The end surface of the first mounted portion faces in a width direction. The second terminal has a second mounted portion, a second main portion and an unmounted portion. The unmounted portion has a second carrier cut-off surface which is an end surface of the unmounted portion. The end surface of the unmounted portion faces in the width direction. The first carrier cut-off surface and the second carrier cut-off surface face in orientations same as each other in the width direction.

Abstract: A connector is provided with terminals, a holding member and holddowns. The holding member has two side portions, two accommodation portions and an island portion. In a pitch direction (X-direction), the accommodation portions are located within a range not larger than the island portion. The terminals are divided into two terminal rows, which correspond to the accommodation portions, respectively. Each of the holddowns has an end wall portion and two side coupling portions. The end wall portions are located at end portions of the connector, respectively, in the pitch direction (X-direction). Each of the side coupling portions couples the end wall portion to either one of the side portions of the holding member. In the up-down direction (X-direction), the holding member does not overlap with the end wall portion.

Abstract: A connector comprises a housing having a bottom portion and terminals including inner terminals. The bottom portion has a projecting portion and two base portions. The projecting portion projects from the base portions in an upper-lower direction (Z-direction). Each of the base portions has at least one predetermined portion. The predetermined portion includes two passing holes and a separating portion. Each of the passing holes passes through the base portion in the upper-lower direction. The separating portion separates the two passing holes from each other in the pitch direction (Y-direction) and is connected to the projecting portion in the lateral direction (X-direction). Each of the inner terminals has a solderable portion. The solderable portions are partially located in the passing holes, respectively.

Abstract: An assembly comprises a first connector and a second connector. The first connector is mateable with the second connector in an up-down direction. The first connector comprises a plurality of first terminals and a first holding member. Each of the first terminals has two pressed contact points and an insertion end portion. The first terminals include at least one primary first terminal and at least one secondary first terminal. The second connector comprises a plurality of second terminals and a second holding member. The second terminals correspond to the first terminals, respectively. Each of the second terminals has two pressing contact points. The second terminals include a primary second terminal and at least one secondary second terminal. A first size S1 and a second size S2 meet a condition of S1?S2, where S1=Sa?D1, and S2=Sb?D2.

Abstract: An electrical connector pair 1 includes a receptacle connector 1a and a plug connector 1b. The receptacle connector 1a includes a first partition wall 12a, and the plug connector 1b includes a second partition wall 12b. When the receptacle connector 1a and the plug connector 1b are fitted together, the first partition wall 12a partitions a portion of the boundary between a third holder and a fourth holder where the second partition wall 12b is not formed such that a first contact 10a and a third contact 10b cannot be seen from a second contact and a fourth contact.

Abstract: A receptacle connector includes a receptacle housing including a housing portion and receptacle terminals connected to plug terminals. The housing portion includes a first principal inner wall face, a second principal inner wall face, and a first-end inner wall face. At least a part of the first-end inner wall face is first receptacle guide faces having a gap width in a Y-axis direction gradually decreasing. The first receptacle guide face guides a plug connector such that the direction of an axial line of the plug connector is lined up in the direction of an axial line of the housing portion by regulating movement of the plug connector.
