Abstract: An electrical connector reduces backlash of the retainer in a main locking state and increases the rigidity of the front plate of the retainer, while providing dimensional stability, and preventing warpage of the locking arms. The electrical connector comprises a front insertion retainer that is locked to the housing in a temporary locking position and in a main locking position. The retainer comprises a front plate having contact passage holes, and locking arms extending rearward from the upper and lower ends of the front plate. A strip extends in the direction of length and protrudes rearward from the center on the back surface of the front plate, and a recessed groove extends on the front surface of the front plate in a position corresponding to the strip. The housing has a recessed groove that mates with the strip when the retainer is in the main locking position.

Abstract: An electrical connector comprises a retainer that is inserted from the front surface of the connector housing and locked to the housing in a temporary locking position and in a main locking position, wherein the state of the retainer in the main locking position can easily be confirmed by visual inspection or by using an inspection probe. The retainer has main locking arms comprising main locking projections which prevent the retainer from being pushed in when the retainer is in the temporary locking position, and which prevent the retainer from being pulled out when the retainer is in the main locking position. The main locking projections are exposed through the housing when the retainer is in the main locking position. The housing has supporting parts that support the back surface of the main locking arms in the vicinity of the main locking projections when the retainer is in the main locking position.

Abstract: An electrical connector comprises an insulating housing having a plurality of contact accommodating cavities extending from a front side to a rear side of the housing. Each of the contact accomodating cavities has a first probe receiving opening formed adjacent thereto. A retainer that is moveable between a temporary locking position and a main locking position is attached to the front side of the housing. The contact accomodating cavities are accesible through the first probe receiving openings when the retainer is in the temporary locking position, and the contact accomodating cavities are accesible through second probe receiving openings formed in the retainer when the retainer is in the main locking position.
