Abstract

In business machine equipment including printers where it is periodical necessary for the operator or machine maintenance personnel to remove the covers and to access internal elements adjacent to electrical wiring, electrical hazards present a problem. Consequently, it is desirable to have a simple means for automatically cutting off the electrical current when the covers are removed. To this end, the present structure provides a two-piece cover set construction wherein mating cover pieces each contain one portion of the electrical connector. In this manner, connector contact is broken when the covers are separated and reestablished when the covers are snapped back into place.

Electrical Connection Across Removable Covers on Business Machine

In business machine equipment including printers where it is periodical necessary for the operator or machine maintenance personnel to remove the covers and to access internal elements adjacent to electrical wiring, electrical hazards present a problem. Consequently, it is desirable to have a simple means for automatically cutting off the electrical current when the covers are removed. To this end, the present structure provides a two-piece cover set construction wherein mating cover pieces each contain one portion of the electrical connector. In this manner, connector contact is broken when the covers are separated and reestablished when the covers are snapped back into place.

A further aspect of the present structure involves the use of a service jumper which is a closed-loop circuit through the second connector receptacle plugged into one of the connector elements to permit the machine to then function during servicing. Of course, the two parts of the cover set cannot be reconnected until the service jumper is removed. With reference to the figure, mating connector plug 2 and receptacle 1 are panel mounted into two simple brackets 3 and 4 which in turn are mounted on the two cover parts 6 and 7.

Papered guide studs 5 mount the upper bracket and engage the lower bracket prior to the engagement of connector halves 1 and 2. Mounting brackets are adjustable to allow for precise alignment required to...
