ABSTRACT:
A connector socket terminal structure (6) of the integrated wire termination system type for accepting wires (12) with complemental mating pins (8) and is especially suitable for use in environmentally sealed aircraft switches. The retainer (10) is disposed in a hollow terminal (2) and serves to lock the wire termination pin (8) in place in the terminal and insure good electrical contact. The retainer (10) is pressure assembled within the terminal bore (2d, 2e) by forming it of slightly larger diameter than of the bore and squeezing it when it is pushed therein. To control the depth of insertion of the retainer (10) in the bore, the bore (2d, 2e) is provided with a shoulder and the retainer is provided with a plurality of sheared tabs (10a) spaced therearound that abut the shoulder to limit its depth of insertion. To fix the retainer (10) rigidly within the bore, a thin section (2g) is formed at the mouth of the bore which is bent or rolled over the bottom edge of the retainer to fix it rigidly between this bent over lip and the shoulder within the bore. This retainer (10) is provided with guiding and centering fingers (10b) and retention fingers (10c) so that when a collared wire termination pin (8) is inserted therein it is centered by the centering and guiding fingers and is clasped below the collar (8c) by the retention fingers (10c) so that it is locked therein for good electrical contact and great pull out strength.
