Abstract

A lamp socket including socket contacts for electrically contacting lamp holder contacts, the lamp socket including a mounting dome that is insertable into a lamp holder and includes a support pin that is linked in a spring elastic manner so that the support pin mechanically anchors the lamp socket in the lamp holder, wherein the mounting dome includes support surfaces which form a movement path along which the support pin is moveable, wherein the movement path displaces the support pin from an idle position in a first direction through a displacement section while building up a spring load during a relative movement of the lamp socket and the lamp holder, wherein the movement path returns the support pin through a return section towards an idle position of the support pin partially reducing the spring load during a relative movement of the lamp socket and the lamp holder.

First claim

What is claimed is:

1. A lamp socket including socket contacts for electrically contacting lamp holder contacts, the lamp socket comprising:
a mounting dome that is insertable into a lamp holder and includes a support pin that is linked in a spring elastic manner so that the support pin mechanically anchors the lamp socket in the lamp holder,
wherein the mounting dome includes support surfaces which define a movement path along which the support pin is moveable,
wherein the movement path displaces the support pin from an idle position in a first direction through a displacement section of the movement path while building up a spring load during a relative movement of the lamp socket and the lamp holder,
wherein the movement path returns the support pin through a return section of the movement path towards an idle position of the support pin partially reducing the spring load during a relative movement of the lamp socket and the lamp holder, and
wherein the movement path maintains the support pin in an arresting position which forms a portion of the return section of the movement path while maintaining a residual spring load during a relative movement of the lamp socket and the lamp holder.

2. The lamp socket according to claim 1 ,
wherein the movement path disengages the support pin from the arresting position during a continued relative movement of the lamp holder and the lamp socket, and
wherein the movement path moves the support pin from the return section into an extraction section of the movement path while reducing the residual spring load to zero during a continued relative movement of holder and lamp socket.

3. The lamp socket according to claim 2 ,
wherein the extraction section displaces the support pin in a second direction building the spring tension up again, and
wherein the second direction is opposite to the first direction of displacement.

4. The lamp socket according to claim 1 , wherein the support surfaces are associated with a support groove fabricated into a side wall of the mounting dome.

5. The lamp socket according to claim 4 ,
wherein the support groove extends from an inlet opening through which the support pin is insertable into the support groove, and
wherein the support groove terminates in an outlet opening through which the support pin is extractable.

6. A system for mechanically fixating a lamp socket in a lamp holder, the system comprising:
the lamp holder including
a recess receiving a mounting dome of a lamp socket,
wherein a spring element is arranged in the recess,
wherein the spring element impacts the lamp socket through a pressure plate, and

a support pin that is arranged in the recess and linked in a spring-elastic manner; and
the lamp socket including
the mounting dome that is insertable into the lamp holder and includes the support pin that is linked in a spring elastic manner so that the support pin mechanically anchors the lamp socket in the lamp holder,

wherein the mounting dome includes support surfaces which define a movement path along which the support pin is moveable,
wherein the movement path displaces the support pin from an idle position in a first direction through a displacement section of the movement path while building up a spring load in the support pin during a relative movement of the lamp socket and the lamp holder,
wherein the movement path returns the support pin through a return section of the movement path towards an idle position of the support pin partially reducing the spring load during a relative movement of the lamp socket and the lamp holder,
wherein the movement path maintains the support pin in an arresting position which forms a portion of the return section of the movement path while maintaining a residual spring load during a relative movement of the lamp socket and the lamp holder,
wherein the mounting dome of the lamp socket is introduced in mounting direction into the receiving cavity of the lamp holder, and
wherein the pressure plate is displaced from an idle position by the mounting dome while building up a spring tension and the pressure plate moving against mounting direction supports the support pin of the support in the arresting position of the movement path, and thus supports the lamp socket in the lamp holder.

7. The system according to claim 6 ,
wherein the movement path disengages the support pin from the arresting position during a continued relative movement of the lamp holder and the lamp socket,
wherein the movement path moves the support pin from the return section into an extraction section of the movement path while reducing the residual spring load to zero during a continued relative movement of the lamp holder and the lamp socket, and
wherein the support pin is disengaged from the arresting position and transferred into the extraction section under a renewed movement of the mounting dome in mounting direction and under a further displacement of the pressure plate.

8. The system according to claim 7 , wherein the spring tension of the pressure plate causes a dismounting movement of the mounting dome which moves the support pin along the extraction section and which causes a spring elastic displacement of the support pin.

9. The system according to claim 8 ,
wherein the extraction section displaces the support pin in a second direction building the spring tension up again,
wherein the second direction is opposite to the first direction of displacement,
wherein the support surfaces are associated with a support groove fabricated into a side wall of the mounting dome,
wherein the support groove extends from an inlet opening through which the support pin is insertable into the support groove,
wherein the support groove terminates in an outlet opening through which the support pin is extractable, and
wherein a frictional engagement between the support pin that is displaced in a spring elastic manner in an extraction section and the support surface of the extraction section supports the support pin in the extraction section and prevents an exit of the support pin through an outlet opening.

10. A system for mechanically fixating a lamp socket in a lamp holder, the system comprising:
the lamp holder including
a recess receiving a mounting dome of a lamp socket,
wherein a spring element is arranged in the recess,
wherein the spring element impacts the lamp socket through a pressure plate, and

a support pin that is arranged in the recess and linked in a spring-elastic manner; and
the lamp socket including
the mounting dome that is insertable into the lamp holder and includes the support pin that is linked in a spring elastic manner so that the support pin mechanically anchors the lamp socket in the lamp holder,

wherein the mounting dome includes support surfaces which define a movement path along which the support pin is moveable,
wherein the movement path displaces the support pin from an idle position in a first direction through a displacement section of the movement path while building up a spring load during a relative movement of the lamp socket and the lamp holder,
wherein the movement path returns the support pin through a return section of the movement path towards an idle position of the support pin partially reducing the spring load during a relative movement of the lamp socket and the lamp holder, and
wherein the movement path maintains the support pin in an arresting position which forms a portion of the return section of the movement path while maintaining a residual spring load during a relative movement of the lamp socket and the lamp holder,
the method comprising the steps:
inserting the mounting dome with a mounting movement in a mounting dire
