  • Patent number: 6554656
    Abstract: A primary compact is formed as a resin article by using a single die to thereby integrally mold a connector housing, a rear holder, and a lock spacer so that the attaching directions of such parts are the same direction. In an assembling process, the connector housing is detached from the primary compact. Subsequently, the rear holder adjoining the connector housing is detached from a sub-runner. Then, a terminal slipping-off preventing piece of the rear holder is inserted into a terminal insertion opening of the connector housing from above the terminal insertion opening. Thereafter, the lock spacer adjoining the rear holder is detached from the sub-runner and inserted into a latching concave portion of the connector housing from above in such a manner as to be in a temporarily caught state. Thus, the parts are assembled into a connector.

  • Patent number: 6412169
    Abstract: In a connector equipped with a rear holder, the rear holder in an open state is coupled with a housing of the connector by a fixing belt. A rear holder mounting device is provided with a cutter and slide bar. The cutter is moved to cut the fixing belt. The slide bar is moved to close the rear holder so that the rear holder is engaged in the housing. Thus, working before mounting the rear holder in the connector can be smoothly carried out. The rear holder, without being damaged or deformed, can be easily mounted in the connector.

  • Patent number: 6382991
    Abstract: A low insertion force connector with a downsized and simple structure and high reliability is provided, wherein coupled connectors are capable of sufficiently moving in the uncoupling direction. The low insertion force connector includes: a first connector having a first cam-projection, a frame with a cam-opening to slidably accommodate the first connector in the coupling direction, a second connector with a coupling portion and a cam-engaging slit to be couples with the first connector in the frame, and a slider attached to the second connector, provided with a second cam-projection which engages both of the cam-opening and the cam-engaging slit, and provided with a cam groove consisting of a connector coupling cam groove and a shift-allowing cam groove continuing to the connector coupling cam groove. Thus, a low insertion force connector with a downsized and simple structure and high reliability can be realized.

  • Patent number: 6383015
    Abstract: Press contact terminals are held in terminal housing chambers of a housing body. A longitudinally intermediate part of a flat circuit is positioned above a top surface opening of the terminal housing chambers. Each conductor of the flat circuit is press-connected to each press contact terminal with a press contact jig. A cover is closed, thereby to fold the flat circuit in two in the vicinity of the press-connected part so that one part is overlaid on the press-connected part. The folded part is sandwiched between the cover and the housing body to be held in a connector housing.

  • Patent number: 6299471
    Abstract: An insulating base plate 113 of a housing 11 includes an upper plate portion 114, a lower plate portion 115, and reinforcing plate portions 116 are formed on and extend between the upper and lower plate portions 114 and 115, and are disposed respectively at those portions of the upper and lower plate portions corresponding respectively to positions where wires of a wire harness W are press-connected to respective terminals. With this construction, the weight of the housing can be reduced because of the provision of hollow portions 117. And besides, since the reinforcing plate portions 116 are formed at those portions of the insulating base plate corresponding respectively to the positions where the wires of the wire harness W are press-connected to the respective terminals, the press-connecting operation can be carried out in a stable manner without flexing the insulating base plate 113.
