Abstract

An LED socket comprises an LED package having an LED mounted on an LED printed circuit board, a contact having a receiving section adapted to be connected to a terminal end of an electrical cable and a contact lug having a T-shaped contact section, and a base defining a receptacle for receiving the LED printed circuit board. The receptacle is open to an opening in the base adapted to expose the LED at a front face of the base. The base holds the contact and the T-shaped contact section is exposed in the receptacle and electrically contacts a pad of the LED printed circuit board.

First claim

What is claimed is:

1. An LED socket, comprising:
an LED package having an LED mounted on an LED printed circuit board;
a contact having a receiving section adapted to be connected to a terminal end of an electrical cable and a contact lug having a T-shaped contact section; and
a base defining a receptacle for receiving the LED printed circuit board, the receptacle is open to an opening in the base adapted to expose the LED at a front face of the base, the base holds the contact and the T-shaped contact section is exposed in the receptacle and electrically contacts a pad of the LED printed circuit board, the contact is adapted to be inserted into a radial slot of the base in a radial direction and is moved in a second direction extending perpendicular to the radial direction within the radial slot.

2. The LED socket of claim 1 , wherein the contact is held in the radial slot of the base in a form-fitting manner.

3. The LED socket of claim 1 , wherein the base has a radial bore receiving the electrical cable and extending in a direction aligned with the receiving section of the contact.

4. The LED socket of claim 1 , wherein the contact has a pressing surface and the base has an oblique counter surface partially defining the radial slot, the pressing surface presses against the oblique counter surface when the contact is moved in the second direction.

5. The LED socket of claim 1 , wherein the base has a guide slot adapted to guide a guide rim of the contact in the radial direction.

6. The LED socket of claim 5 , wherein the guide slot and the guide rim permit movement of the contact in the second direction after the contact reaches a final insertion position in which the contact abuts a boundary surface of the base.

7. The LED socket of claim 6 , wherein the base has a housing latch and the contact has a higher portion cooperating with the housing latch to secure the contact in an assembled position of the contact in the base.

8. The LED socket of claim 7 , wherein the housing latch defines a securing receptacle open to the guide slot and the higher portion is aligned with the securing receptacle.

9. The LED socket of claim 7 , wherein the contact has a locking projection and the base has a holding notch extending in the second direction, the locking projection is aligned with the holding notch and engages the holding notch in the assembled position.

10. The LED socket of claim 9 , wherein the contact has a downholder section and the base has a downholding slot receiving the downholder section in the assembled position.

11. The LED socket of claim 1 , wherein the LED package is attached to the base by an adhesive tape.

12. A base of an LED socket, comprising:
a receptacle for receiving an LED printed circuit board of an LED package having an LED mounted on the LED printed circuit board;
an opening adapted to expose the LED at a front face of the base;
a securing device adapted to secure a contact in the base, the contact having a contact lug electrically contacting a pad of the LED printed circuit board;
a radial slot extending in a radial direction toward the receptacle and receiving the contact, the radial slot defines a guide slot adapted to receive a guide rim of the contact and extending in the radial direction toward the receptacle; and
an oblique counter surface partially defining the radial slot and extending in the radial direction, the oblique counter surface is inclined in a second direction extending perpendicular to the radial direction.

13. The base of claim 12 , wherein the base is integrally formed in a single piece by injection molding.

14. The base of claim 12 , further comprising a housing latch disposed within the radial slot and defining a securing receptacle adapted to receive a higher portion of the contact in a form-fitting manner.

15. The base of claim 14 , wherein the securing receptacle is open to the guide slot and defined within a ridge extending in the radial direction and defining the guide slot within the radial slot.

16. The base of claim 12 , further comprising a holding notch extending in a second direction perpendicular to the radial direction and terminating in the radial slot.

17. The base of claim 12 , further comprising an adhesive tape adapted to fix the LED package in the receptacle.

18. The base of claim 17 , wherein the adhesive tape has a first adhesive surface fixed to the base and a second adhesive surface adapted to be fixed to the LED package and covered by a protective liner.

19. A base of an LED socket, comprising:
a receptacle for receiving an LED printed circuit board of an LED package having an LED mounted on the LED printed circuit board;
an opening adapted to expose the LED at a front face of the base;
a securing device adapted to secure a contact in the base, the contact having a contact lug electrically contacting a pad of the LED printed circuit board;
a radial slot extending in a radial direction toward the receptacle and receiving the contact; and
a holding notch extending in a second direction perpendicular to the radial direction and terminating in the radial slot.
