A compact vehicle-mounted electrical outlet box offering a reliable plug blade detection function. The electrical outlet box is formed from synthetic resin rectangular casewhich includes bodyand coverA pair of electrical plug bladesandare inserted into plug blade insertion slotslocated on the front surface of casethrough which the plug blades contact two blade receiver partsThe forceful contact of plug bladesandrotate two pivot leverswhich convert the insertion force of plug bladesandto a directional force. Two return springsapply pressure to pivot leversin a direction opposite to that applied by the insertion of plug bladesandPrinted circuit blockwhich is comprised of circuit base plateto which each microswitchis installed, is housed within caseThe two pivot leversare located at the approximate mid-point of bodybetween the two mutually facing blade receiver parts.

Power point

A wall bracket for mounting wiring devices comprises a flat frame having first and second jambs which define therebetween an opening for receiving the body portions of the wiring devices. The wiring device has a strap having mounting ears projecting on either side of the device and is attached to the frame with the mounting ears engaged into first and second slots formed in the frame. The first slots are formed in the first jamb and open to the opening for receiving the mounting ears on one side of the device. The second slots for receiving the mounting ears on the other side of the device are formed in a resilient strip extending along the second jamb in spaced relation outwardly thereof. The resilient strip is integrally connected at its longitudinal ends to the ends of the second jamb respectively through U-shaped hinge sections which are bent within the plane of the frame so that the resilient strip is capable of flexing outwardly within that plane to permit the snap engagement of the mounting ears into the second slots. With the hinge connections within the plane of the frame, it is possible to minimize the amount of rearward projection of the resilient strip yet assuring the snap engagement due to the flexing of the resilient strip.

Bracket for mounting wiring devices

Surface-mounting wiring device wherein a cover assembly mounted on a base carrying terminal members for covering them has a double structure of an inner cover and an outer decorative cover, the inner cover facing directly toward the terminal members is heat resistant, and the decorative cover exchangeably fitted over the inner cover is impact resistant, whereby the two conditions of heat and impact resistance are simultaneously satisfied, while the exchangeable decorative cover allows the device to have any desired appearance.
