Abstract

Conventional methods for mounting electro-optical components, such as photodiodes, to the surface of a printed circuit board include the use of labor intensive brackets and fastening devices, such as screws or adhesive. The present invention provides a relatively small and simple component holder, which is easily attached to a circuit board by inserting the lower portion of the holder through a “key-hole” slot in the circuit board and rotating the upper portion, thereby squeezing the circuit board between the upper and lower portions. The component holder according to the present invention enables the electro-optical component to be mounted flush with the upper surface of the circuit board. Moreover, flexible locking elements enable the component holder to be mounted onto circuit boards of various thicknesses.

Claims

1. A component holder device for securing an electro-optical component substantially flush with an upper surface of a printed circuit board, the printed circuit board including a slot for receiving the component holder, the component holder comprising:

first and second base sections, each base section having a lower surface for substantially flush engaging the upper surface of the printed circuit board;

first and second resilient arms extending from the first and second base sections, respectively, for clamping the electro-optical component therebetween, the first and second resilient arms forming a cavity which extends substantially level with the lower surface of the first and second base sections, whereby the electro-optical component will be mounted substantially flush with the upper surface of the printed circuit board;

a body extending from the first and second base sections for extending through the slot;

first and second resilient feet extending outwardly from the body for engaging a lower surface of the printed circuit board after the body has been inserted through the slot and the component holder has been rotated.

2. The device according to claim 1, wherein at least one of the resilient arms includes a camming surface at an outer free ends thereof for facilitating insertion of the electro-optical component therebetween.

3. The device according to claim 1, wherein each foot includes a toe extending upwardly from an outer free end thereof for contacting the lower surface of the printed circuit board to ensure that the printed circuit board is firmly held between said bases and said feet.

4. The device according to claim 3, wherein each toe includes beveled front and rear surfaces for acting as a camming surface upon initial engagement with the lower surface of the circuit board.

5. The device according to claim 1, wherein the body includes two flexible legs extending perpendicularly to the first and second base sections for providing increased flexibility to the feet, which extend therefrom.

6. The device according to claim 1, wherein the first and second arms are C-shaped.

7. The device according to claim 1, wherein the first and second bases are superposed above the first and second feet, respectively.

8. The device according to claim 1, wherein the component holder device is of a unitary plastic construction.

9. The device according to claim 1, wherein the first and second feet are rectangular for insertion through rectangular portions of the slot, and wherein the body is round for insertion through a round portion of the slot.

10. A component holder device for securing an electro-optical component substantially flush with an upper surface of a printed circuit board, the printed circuit board including a slot for receiving the component holder, the component holder comprising:

a body for extending through the slot;

first and second resilient arms extending from the body for clamping the electro-optical component therebetween, the first and second resilient arms forming a cavity which extends substantially level with the upper surface of the printed circuit board, whereby the electro-optical component can be mounted substantially flush with the upper surface of the printed circuit board;

first and second bass sections extending from the first and second resilient arms respectively, each base section having a lower surface for substantially flush engaging the upper surface of the printed circuit board;

first and second resilient feet extending outwardly from the body for engaging a lower surface of the printed circuit board after the body has been inserted through the slot and the component holder has been rotated.

11. The device according to claim 10, wherein at least one of the resilient arms includes a camming surface at an outer free ends thereof for facilitating insertion of the electro-optical component therebetween.

12. The device according to claim 10, wherein each foot includes a toe extending upwardly from an outer free end thereof for contacting the lower surface of the printed circuit board to ensure that the printed circuit board is firmly held between said bases and said feet.

13. The device according to claim 12, wherein each toe includes beveled front and rear surfaces for acting as a camming surface upon initial engagement with the lower surface of the circuit board.

14. The device according to claim 10, wherein the body includes two flexible legs extending perpendicularly to the first and second base sections for providing increased flexibility to the feet, which extend therefrom.

15. The device according to claim 10, wherein the first and second arms are C-shaped.

16. The device according to claim 10, wherein the first and second bases are superposed above the first and second feet, respectively.

17. The device according to claim 10, wherein the component holder device is of a unitary plastic construction.

18. The device according to claim 10, wherein the first and second feet are rectangular for insertion through rectangular portions of the slot, and wherein the body is round for insertion through a round portion of the slot.
