Abstract

A lamp assembly for a vehicle comprising a housing, a reflector mounted in the housing, a light source, a printed circuit board or PCB mounted on a heatsink of the lamp assembly and coupled to the light source to control operation of the light source. The PCB has a first connector for coupling to a second connector comprising a body having a plurality of resilient or elastic arms that each have a detent for locking the connector to the component and retain electrical contact with the PCB. The wall of the heatsink defines an aperture for receiving the second connector and provides a locking surface that deflects the arms towards the body while engaging and cooperating with the detests to lock the connector to the PCB. The free end of the arms extend beyond the mounting wall and are actuated to unlock the connector from the PCB.

First claim

What is claimed is:

1. A connector of a light module of a vehicle, the connector comprising:
a body; and
at least one arm having a first end integrally formed with the body, the at least one arm having at least one detent for locking the connector to a component of the light module when the body of the connector is connected to mating connections disposed on a surface of a printed circuit board, the at least one detent being disposed between the first end of the at least one arm and a second end of the at least one arm and configured to engage a wall of the component of the light module, wherein
when the body of the connector is connected to the mating connections of the printed circuit board, the at least one arm does not extend beyond the surface of the printed circuit board, the surface of the printed circuit board facing an opening of the component of the light module, the opening of the component of the light module defining a passage through which the body of the connector is connected to the mating connections of the printed circuit board.

2. The connector as recited in claim 1 , wherein the at least one arm includes a plurality of arms, each one of the plurality of arms having at least one detent for locking the connector to the component of the light module and retaining the connector in electrical contact with the mating connections of the printed circuit board.

3. The connector as recited in claim 2 , wherein each one of the plurality of arms is dimensioned such that they extend beyond a visible surface of the wall of the component of the light module so that they can be accessed and actuated toward the body when it is desired to disconnect the connector from the mating connections of the printed circuit board.

4. The connector as recited in claim 2 , wherein the component of the light module is at least one of a heat sink, a headlamp bezel, or a headlamp housing.

5. The connector as recited in claim 1 , wherein the at least one arm is resilient or elastic such that
when the connector is connected to the mating connections of the printed circuit board, the at least one arm is deflected or calmed toward the body, and
when the connector becomes connected to the mating connections of the printed circuit board, the at least one arm is biased to a locked position whereupon the at least one detent engages a hidden surface of the wall of the component of the light module to lock the connector to the printed circuit board.

6. The connector as recited in claim 1 , wherein each of the at least one detent comprises a shoulder or a step integrally formed in the at least one arm and adapted to define the at least one detent that engages a hidden surface of the wall of the component of the light module in order to retain the connector in a locked position relative to the printed circuit board.

7. The connector as recited in claim 1 , wherein the second end of the at least one arm is a free end adapted to move towards and away from the body during connection and disconnection of the connector with the mating connections of the printed circuit board.

8. The connector as recited in claim 1 , wherein the component of the light module is at least one of a heat sink, a headlamp bezel, or a headlamp housing.

9. The connector as recited in claim wherein, when the body of the connector is connected to the mounting connections of the printed circuit board, the body of the connector is at least partially surrounded by the component of the light module.

10. A lamp assembly of a vehicle, the lamp assembly comprising:
a housing;
a reflector mounted in the housing;
at least one light source operatively associated with the reflector; and
a printed circuit board mounted on a component of the lamp assembly and coupled to the at least one light source, the printed circuit board controlling an operation of the at least one light source, a surface of the printed circuit board facing an opening of the component of the lamp assembly, wherein
the printed circuit board has, disposed on the surface of the printed circuit board, a first connector for coupling to a second connector, the second connector including
a body, and
a plurality of arms, each of the plurality of arms having a first end integrally formed with the body, each one of the plurality of arms having at least one detent for locking the second connector to the component of the lamp assembly and retaining the second connector electrical contact with the first connector of the printed circuit board, the at least one detent of each one of the plurality of arms being disposed between the first end of an arm and a second end of the arm and configured to engage a wall of the component of the lamp assembly, wherein

when the body of the second connector is in the electrical contact with the first connector of the printed circuit board via mating connections, each one of the plurality of arms does not extend beyond the surface of the printed circuit board, the opening of the component of the lamp assembly defining a passage through which the body of the second connector is connected to the first connector of the printed circuit board.

11. The lamp assembly as recited in claim 10 , wherein each one of the plurality of arms is resilient or elastic such that
when the second connector is moved toward the first connector of the printed circuit board via the opening, the plurality of arms are deflected or cammed toward the body, and
when the second connector is connected to the first connector of the printed circuit board, the plurality of arms are moved to a locked position whereupon the at least one detent engages a hidden surface of the wall of the component of the lamp assembly to lock the second connector to the printed circuit board.

12. The lamp assembly as recited in claim 10 , wherein each of the at least one detent includes a shoulder or a step integrally formed in the plurality of arms and is adapted to engage a hidden surface of the wall of the component of the lamp assembly in order to retain the second connector in a locked position on the printed circuit board.

13. The lamp assembly as recited in claim 10 , wherein the second end of each one of the plurality of arms is a free end adapted to move towards and away from the body during connection and disconnection of the second connector with the first connector of the printed circuit board.

14. The lamp assembly as recited in claim 10 , wherein each of the plurality of arms is dimensioned such that they extend beyond a visible surface of the wall of the component of the lamp assembly so that they can be accessed and moved toward the body when it is desired to disconnect the second connector from the first connector of the printed circuit board.

15. The lamp assembly as recited in claim 10 , wherein the component of the lamp assembly is at least one of a heat sink, a headlamp bezel, or a headlamp housing.

16. The lamp assembly as recited in claim 10 , wherein the component of the lamp assembly is a heat sink having the at least one light source and the printed circuit board mounted thereon, the opening of the heat sink defining a mounting wall, the mounting wall providing
a contacting surface that deflects the plurality of arms towards the body when the second connector is moved toward the first connector of the printed circuit board, and
the hidden surface that engages each of the at least one detent of the plurality of arms to lock the second connector to the printed circuit board.

17. The lamp assembly as recited in claim 16 , wherein the second end of the plurality of arms is a free
