Retention Screw Retaining Ring Assembling Apparatus

An apparatus is provided which permits the assembling of retaining rings on printed-circuit card connectors while eliminating the handling of any special tools.

As shown in the figure, the apparatus includes a base 11 which supports the printed-circuit card with a connector assembly. The base has two locating holes 13, 15 for the retention screws to hold the connector prior to assembling the retainer rings. Two slots 17 and 19 are milled at right angles in the metal base, one being at a right angle to the connector housing. This will guide the retaining ring 21 to be positioned in the groove 17 so that it may be inserted into the printed-circuit board assembly by the applicator 23. The ring applicator 23 captures the retaining ring 21 and inserts the ring into the slot of the retention screw, following which the applicator is withdrawn and made ready for the next assembly.

This apparatus provides guidance and support for assembling the screw retainer rings in a relatively confined area and lends itself to a simple assembly technique applicable to existing board stiffener assemblies.
