Abstract
Abstract A plug connection with a plug (11) and an associated counterpart plug or socket (12) is intended to be formed such that shaping strains acting upon it have no or only slight disturbing influence on the contacts (25, 28) of the plug connection. To that end, the plug (11) has a packing element (19), supported on its outside in a contact carrier (14), in the form of an uninterrupted, encompassing radial rubber elastic element which, in addition to a framelike basic body (37), engages socket (12), also contains pinlike retaining segments (41), which are oriented inward, press resiliently against the contact elements (25) of the plug (11) and stabilize them in their position. This plug connection is preferably used in motor vehicles, in whose operation strong shaking strains must be expected, e.g. having Diesel engines.

Claim 1
Independent Claim
216 words
An electric plug connection comprising a plug (11) having a plug housing (13); a counterpart socket (12), said plug housing (13) being dimensioned to be received in said counterpart socket (12) and defining an outer surface located within said counterpart socket; a contact part (28) located in the counterpart socket; a contact carrier (14) located in the plug housing and made of electrically insulating material, said contact carrier being formed with a receiving chamber (22); a contact element (25) located in said chamber and supported therein; a connection segment (29) including a contact segment (26) for connection to an electric line (31), electrically conductively and mechanically connectable via said contact segment (26) with the contact part (28) within the counterpart socket (12); an intermediate segment (32) located between said connecting segment (29) and the contact segment (26) of the contact element (25); and a packing element (19) located in the plug (11) and, in connected or plugged-in state of the connection, coupling the plug (11) to the counterpart socket (12), wherein the packing element (19) includes an uninterrupted, circumferentially closed rubber-elastic element comprising a base body (37) circumferentially engaging the outer surface of the contact carrier (14), and a retaining segment (41) located and guided in a transverse bore (24) extending through the contact carrier (14).
Claim 2
Dependent Claim
216 words
An electric plug connection comprising a plug (11) having a plug housing (13); a counterpart socket (12), said plug housing (13) being dimensioned to be received in said counterpart socket (12) and defining an outer surface located within said counterpart socket; a contact part (28) located in the counterpart socket; a contact carrier (14) located in the plug housing and made of electrically insulating material, said contact carrier being formed with a receiving chamber (22); a contact element (25) located in said chamber and supported therein; a connection segment (29) including a contact segment (26) for connection to an electric line (31), electrically conductively and mechanically connectable via said contact segment (26) with the contact part (28) within the counterpart socket (12); an intermediate segment (32) located between said connecting segment (29) and the contact segment (26) of the contact element (25); and a packing element (19) located in the plug (11) and, in connected or plugged-in state of the connection, coupling the plug (11) to the counterpart socket (12), wherein the packing element (19) includes an uninterrupted, circumferentially closed rubber-elastic element comprising a base body (37) circumferentially engaging the outer surface of the contact carrier (14), and a retaining segment (41) located and guided in a transverse bore (24) extending through the contact carrier (14).
Claim 3
Dependent Claim
41 words
The plug connection of claim 1, wherein the retaining segment (41), transversely to the longitudinal direction of the contact element (25), resiliently rests with a first side on the contact element and, with a second side, on the base body (37).
Claim 4
Dependent Claim
22 words
The plug connection of claim 1, wherein the retaining segment (41) rests on the intermediate segment (32) of the contact element (25).
Claim 5
Dependent Claim
22 words
The plug connection of claim 2, wherein the retaining segment (41) rests on the intermediate segment (32) of the contact element (25).
Claim 6
Dependent Claim
44 words
The plug connection of claim 1, wherein the base body (37) of said rubber-elastic element is formed with projecting beads (39) protruding from the outer circumferential surface thereof and, in plugged-in state of the connection, sealing the plug (11) to the counterpart socket (12).
