Abstract

A panel mount electrical connector has a flange (24) and a locking ramp (40) forward of the flange. The flange and the locking ramp are arranged to be disposed on opposite sides of a mounting panel when the connector is disposed in a cutout of the panel. The locking ramp is inclined with respect to the flange such that the panel will become captured between the locking ramp and the flange when the connector is twisted in the cutout.

Claims

1. A connector which is mountable in a cutout of a panel, the connector comprising:

a housing having a longitudinal axis, a forward portion which is insertable through the cutout, a flange rearward of the forward portion and dimensioned larger than the cutout to prevent passage of the flange through the cutout, and a pair of locking ramps extending laterally from diametrically opposite sides of the forward portion and spaced from the flange, said pair of locking ramps each being inclined with respect to said panel surface and each extends an angular distance around said housing for at least 90° and

less than 180°

, the locking ramps being inclined with respect to the flange wherein the locking ramps cooperate with the flange to capture the panel wedgingly between opposing portions of the locking ramps and the flange when the housing is rotated on the axis.

2. The connector of claim 1 wherein the flange is continuous around the housing.

3. The connector of claim 2 wherein the flange is configured to engage the panel continuously around the cutout.

4. The connector of claim 1 wherein said housing is molded of plastics material and said first and second locking ramps are integrally molded portions thereof.

5. The connector of claim 1 wherein said pair of locking ramps are spaced apart around said housing to permit passage therebetween of tabs of said panel inwardly directed into said cutout from opposing sides thereof as said housing is being inserted through said cutout, where-after said housing is rotated to wedge said tabs between respective ones of said pair of locking ramps and opposing portions of said flange axially spaced therefrom.

6. The connector of claim 1 wherein said pair of locking ramps having flat rear surfaces facing and engageable with said panel during rotation of the housing.

7. The connector of claim 1 wherein said flange includes a plurality of strengthening ribs extending along a rearwardly facing surface thereof.
