Abstract
Abstract The present invention is directed to an electrical plug-in socket, especially for motor vehicles, which has a hinged lid, a compression spring, for the hinged lid, a chamber for the compression spring molded to the socket housing, and a cam provided with a control curve and molded to the hinged lid. The cam cooperates in such a way with the compression spring, that the hinged lid is automatically held in one of the closed and the open position. In order to simplify the assembly or installation of the hinged lid and in order to lower the material and installation costs, the compression spring is designed as a leaf spring and is molded into the chamber of the plug-in socket housing. The leaf spring has a spherical section-shaped rise for the control curve of the cam.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
An electric plug-in socket, especially for motor vehicles, comprising: a housing; a hinged-lid, wherein said hinged-lid is connected to said housing; a chamber, wherein said chamber is formed in said housing; a spring device, wherein said spring device has a spherical section formed integrally thereon, wherein said spring device is used in conjunction with said hinged-lid, and further wherein said spring device is formed integrally with said housing, and further wherein said spring device is located in a spring device chamber which is formed in said housing; and a cam device, wherein said cam device is formed integrally with said hinged-lid, and wherein said cam device is provided with a control curve which is utilized in conjunction with said spring device, wherein said hinged-lid is automatically held in one of a closed position and an open position.
Claim 2
Dependent Claim
137 words
An electric plug-in socket, especially for motor vehicles, comprising: a housing; a hinged-lid, wherein said hinged-lid is connected to said housing; a chamber, wherein said chamber is formed in said housing; a spring device, wherein said spring device has a spherical section formed integrally thereon, wherein said spring device is used in conjunction with said hinged-lid, and further wherein said spring device is formed integrally with said housing, and further wherein said spring device is located in a spring device chamber which is formed in said housing; and a cam device, wherein said cam device is formed integrally with said hinged-lid, and wherein said cam device is provided with a control curve which is utilized in conjunction with said spring device, wherein said hinged-lid is automatically held in one of a closed position and an open position.
Claim 3
Dependent Claim
54 words
The electric plug-in socket of claim 1, wherein said control curve has two depressions formed therein, and wherein said spherical section of said spring device is utilized in conjunction with at least one of said two depressions in order to support said hinged-lid in at least one of an open and a closed position.
Claim 4
Dependent Claim
51 words
The electric plug-in socket of claim 1, wherein said cam comprises: an edge in a length of said control curve for changing one of a closing motion of said hinged-lid into an opening motion of said hinged-lid and an opening motion of said hinged-lid into a closing motion of said hinged-lid.
Claim 5
Dependent Claim
51 words
The electric plug-in socket of claim 2, wherein said cam comprises: an edge in a length of said control curve for changing one of a closing motion of said hinged-lid into an opening motion of said hinged-lid and an opening motion of said hinged-lid into a closing motion of said hinged-lid.
