Abstract

An electrical double plug and socket connector includes a socket component, a plug component and a short-circuit bridge. Each of the socket and plug components includes an insulating material housing. Metallic contacts are arranged in the socket component housing, and associated metallic connecting elements are arranged in the plug component housing. The plug component housing bounds a receiving space located between the connecting elements. The short-circuit bridge includes a U-shaped spring accommodated in the receiving space but having two arms which project axially out of the receiving space toward associated insulating material lugs of the socket component housing to such an extent that the connecting elements project beyond the arms by more than the distance by which the lugs extend beyond the contacts. The arms have respective contact webs which respectively extend toward and resiliently contact associated inwardly facing surface portions of the connecting elements in an inoperative position of the components, so that the short-circuit bridge provides a short-circuit connection between the connecting elements, and actuating portions which respectively extend into the path of movement of the lugs toward an operative position, so that the contact webs are resiliently moved away from the connecting elements and the short-circuit connection is interrupted.

Claims

1. An electrical double plug and socket connector comprising

a socket component including

a first insulating material housing centered on an axis and having two axially spaced ends,

two metallic contacts arranged in said first insulating material housing, and

insulating material lugs mounted on said first insulating material housing and projecting substantially axially from one of said ends to a predetermined distance beyond said contacts;

a plug component guided on said socket component for axial movement between at least one inoperative and one operative position and including

a second insulating material housing having two spaced axial ends one of which faces said one end of said socket component in said positions and bounding a centrally located receiving space which is open toward said one axial end of said plug component, and

two metallic connecting elements arranged in said second insulating material housing outwardly of and projecting axially beyond said receiving space and each having an inwardly facing surface portion; and

a resilient short-circuit bridge including a substantially U-shaped spring arranged between the two connecting elements, predominantly accommodated in said receiving space of said second insulating material housing, and having two arms having respective end portions projecting axially out of said receiving space toward said insulating material lugs of said first insulating material housing to such an extent that said connecting elements project beyond said end portions of said arms by more than said predetermined distance,

said end portions of said arms having respective contact webs which respectively extend toward and resiliently contact the associated ones of said inwardly facing surface portions of said connecting elements in said inoperative position for the short-circuit bridge to provide a short-circuit connection between said connecting elements, and actuating portions which respectively extend into the path of movement of said two insulating material lugs for said insulating material lugs to move said contact webs resiliently away from said connecting elements as said plug component approaches said operative position thereof relative to said socket component to interrupt said short-circuit connection.

2. The electrical double plug and socket connector as defined in claim 1, wherein said contact webs are bent out of said end portions of said arms of said U-shaped spring while the remainders of said end portions of said arms constitute said actuating portions and have inclined ramp surfaces which come into contact with said insulating material lugs of said socket component as said plug component approaches said operative position thereof relative to said socket component.
