Abstract

A clip is disclosed which is capable of applying significant retention force via a rotatable cam arm while being easily removable due to the cam arm and a separate removal arm. A method of using the clip is also disclosed which uses the advantages of the clip, particularly in the context of computer design and construction.

Claims (24)

1. A method of installing a retainer clip comprising:

applying force together and in opposite directions to a removal arm located on one end of a retainer clip body and a rotatable cam arm located generally in the middle of the retainer clip body, wherein the cam arm is rotated to a position generally parallel to the removal arm, such that the force temporarily deforms the retainer clip body such that a first latching portion and a second latching portion of the retainer clip are separated;

lowering the retainer clip onto a retaining member such that the first latching portion and the second latching portion advance beyond respective first and second engagement structures located on the retaining member; and

releasing the removal arm and the cam arm such that the retainer clip body is no longer deformed and the first and second latching portions engage with their respective first and second engagement structures.

2. The method of claim 1 , further comprising the act of rotating the cam arm to a position generally parallel to the retainer clip body.

3. The method of claim 2 , further comprising the act of disposing a retained component between the retainer clip body and the retaining member.

4. The method of claim 3 , wherein the act of rotating presses the retained component against the retaining member due to the action of two or more cam arm side structures which extend beneath the retainer clip body when the cam arm is generally parallel to the retainer clip body.

5. A method of installing a retainer clip comprising:

providing a retainer clip comprising a retainer clip body, wherein the retainer clip is configured such that applying force together and in opposite directions to a removal arm, located at one end of the retainer clip body, and a rotatable cam arm, located generally in the middle of the retainer clip body, temporarily deforms the retainer clip body such that a first latching portion and a second latching portion of the retainer cup are separated; and

pressing the retainer clip onto a retaining member such that the first latching portion and the second latching portion engage respective first and second engagement structures located on the retaining member.

6. The method of claim 5 , comprising the act of disposing a retained component between the retainer clip body and the retaining member.

7. The method of claim 5 , comprising the act of rotating the cam arm to a position generally parallel to the retainer clip body.

8. The method of claim 7 , wherein the act of rotating presses a retained component against the retaining member due to the action of two or more cam arm side structures which extend beneath the retainer clip body when the cam arm is generally parallel to the retainer clip body.

9. The method of claim 5 , wherein the rotatable cam arm is rotated to a position generally parallel to the retainer clip body prior to pressing the retainer clip onto a retaining member.

10. A method of manufacturing a computer system comprising:

providing a circuit board comprising a retaining member;

disposing a retained component on the retaining member;

providing a retainer clip comprising a retainer clip body, wherein the retainer clip is configured such that applying force together and in opposite directions to a removal arm, located at one end of the retainer clip body, and a rotatable cam arm, located generally in the middle of the retainer clip body, temporarily deforms the retainer clip body such that a first latching portion and a second latching portion of the retainer clip are separated; and

securing the retained component to the retaining member by pressing the retainer clip onto the retaining member such that the first latching portion and the second latching portion engage respective first and second engagement structures located on the retaining member.

11. The method of claim 10 , comprising the act of rotating the cam arm to a position generally parallel to the retainer clip body.

12. The method of claim 11 , wherein the act of rotating presses the retained component against the retaining member due to the action of two or more cam arm side structures which extend beneath the retainer clip body when the cam arm is generally parallel to the retainer clip body.

13. The method of claim 10 wherein the rotatable cam arm is rotated to a position generally parallel to the retainer clip body prior to pressing the retainer clip onto the retaining member.

14. The method of claim 10 wherein the retained component comprises a heatsink.

15. The method of claim 10 wherein the circuit board comprises a mother board.
