Abstract

On certain electronic units, it is frequently necessary to provide multiple identical connectors for interconnection of related units such as, for example, an I/O control unit attachment to keyboards or printers. Using identical connector units frequently results in interconnection of nonrelated units or requires labeling of the various units.

Connection Alignment Pin with Selectable Key

On certain electronic units, it is frequently necessary to provide multiple identical connectors for interconnection of related units such as, for example, an I/O control unit attachment to keyboards or printers. Using identical connector units frequently results in interconnection of nonrelated units or requires labeling of the various units.

The illustrated connector unit includes a male member 1 and a female member 2, the individual pins 3 being positioned to conform to the openings 4 in the unit 2. The connector further includes a selectable alignment pin 5 and the corresponding female receptacle comprises a matching keyway 6, which will be keyed to the same position as alignment pin 5 to eliminate interconnection of the wrong units during installation, and facilitate detachment of the devices without labeling for servicing or fault isolation. The selectable alignment pin 5 is keyed to rotate on its long axis through several positions on a detent.

In the illustrated embodiment shown by way of example, the alignment pin rotates through 8 positions on a detent, while the female receptacle 6 comprises a matching relatively heavy keyway which is also rotated through a similar detent. The alignment pin 5 and the matching keyway 6 may be set at the factory or in the field, and incorrect interconnection of related devices is avoided by setting the various alignment pin/keyways in different positions of the detent. Thus a...
