1,249,602. Two-part couplings. INTERNATIONAL STANDARD ELECTRIC CORP. 15 Jan., 1970 [21 Jan., 1969], No. 1970/70. Heading H2E. A printed circuit board connector has contacts 16, 18 held in an insulating contact carrier formed of an upper portion 44 and a lower portion 46 joined at the ends by posts (74, Fig. 1, not shown), the contact carrier being positioned in a stainless steel housing 80 fastened to a mounting block 130 screwed on to a mounting plate 150. The contacts pass through slots 96 formed in insulating plates 90 whose outer surfaces have projections 92 and ramps 94 which co-act with recesses 86 and ramps 88 formed on the housing walls, as seen in Fig. 3. With the projections 92 fitted in the recesses 86 the printed circuit board 160 is inserted in the connector and a cam 102 is rotated counterclockwise into the position shown. The cam bears upon a plate 100 and the end of the housing 80 and forces the housing to the left as seen in Fig. 3 thus causing the plates 90 to move along the ramps 94, 88 and force the contacts 16, 18 into engagement with the printed circut conductors 162. The opposite ends of the contacts 16, 18 are alternately offset as shown in Fig. 5. T-shaped keys may be inserted in grooves 62 in the upper surface of the upper portion 44 of the contact carrier which keys mate with corresponding polarizing slots in the inserted board. An elastomer seal 140 is provided on the connector and the contacts may initially be mounted on strips (12, Fig. 1, not shown) for mounting in the connector. Instead of the cam 102 two axial cylinders with slanting end faces (Fig. 7, not shown) may be used to move the housing 80. |
