Abstract

A connector alignment block is described for connecting card-on-board (COB) power supplies into solid logic technology (SLT) boards. This mechanism prevents shroud and pin breakage on insertion of power supply connectors onto back panel pins. COB power supplies use SLT card connectors to plug into SLT boards. Due to size and weight of power supply assemblies, they cannot be easily maneuvered into position for insertion without causing breakage of shrouds on the connectors and pins on the board. The alignment block described herein will align the power supply card accurately over the board pins prior to making pin/receptacle contact, thus preventing breakage.

Connector Alignment Block

A connector alignment block is described for connecting card-on-board (COB) power supplies into solid logic technology (SLT) boards. This mechanism prevents shroud and pin breakage on insertion of power supply connectors onto back panel pins. COB power supplies use SLT card connectors to plug into SLT boards. Due to size and weight of power supply assemblies, they cannot be easily maneuvered into position for insertion without causing breakage of shrouds on the connectors and pins on the board. The alignment block described herein will align the power supply card accurately over the board pins prior to making pin/receptacle contact, thus preventing breakage. Flared openings in the alignment block, using existing card guide prongs as pilots, will position connectors accurately over the pins, compensating for misalignment of up to Å 0.08 inch in the horizontal axis and Å 0.10 inch in the vertical axis. Fig. 1 shows a plan view of a portion of a power supply card 2 and a portion of the mating back panel board 4 into which it is to be plugged. Fig. 2 shows cross-sectional views taken along section line A - A of Fig. 1.

A guide block 1 is mounted on the power supply card 2 so as to be located in proper relationship to the connectors 3. The back panel board 4 with its card guide prongs 5 will make positive engagement with the guide block 1 on closure before contact of pins 6 with the connector 3. A flared portion 7 of the guide block openings ...
