Abstract

A holder for an electrical or electronic component includes a body formed of electrically non-conductive material having a recess to receive a component such as a fuse. At least two laterally spaced electrically conductive contacts are accommodated by the body. Each contact includes at least one aperture engaging section extending beyond a surface of the body to form a solderless low resistance electrical and mechanical connection with a plated through-hole in a printed circuit board or the like and a terminal section to contact a terminal of a component received by the body.

Claims

1. A holder for holding an electrical component having terminals on ends thereof, said holder being engageable with a printed circuit board having plated through-holes formed therein, said holder comprising:

an insulated body to receive the electrical component,

at least two laterally spaced electrically conductive contacts accommodated by said body, each of said contacts including;

at least one aperture engaging section extending beyond a surface of said body to frictionally engage with a respective plated through-hole in the printed circuit board to form a solderless electrical and mechanical connection therewith and

a resilient terminal section to contact a respective terminal of the component and retain the component received by said body,

said terminal sections are in the form of open loops and a restoring force is presented on said loops when compressed to bias said loops against said component.

2. A holder as defined in claim 1 wherein said body is formed of plastic material.

3. A holder as defined in claim 2 wherein said body has an elongate recess provided in an upper surface thereof to receive said component.

4. A holder as defined in claim 3 further including at least one access provided in at least one wall of said body adjacent said recess to facilitate removal of a component accommodated by said recess.

5. A holder as defined in claim 4 wherein said at least one access is in the form of a notch or window provided in said at least one wall.

6. A holder as define in claim 1 wherein said terminal sections are compressed when the component is accommodated by said body.

7. A holder as defined in claim 1 wherein said at least one aperture engaging sections include C-shaped sections formed by oppositely extending arcuate arms which taper in reduced cross-sectional thickness towards their ends, said arms providing generally uniformly stressed beam sections which allow the outer diameter of said C-shaped sections to conform to an inside diameter of a respective one of said plated through-holes into which said aperture engaging ends are inserted.

8. A holder as defined in claim 1 wherein each of said contacts includes a pair of aperture engaging sections.

9. A holder as defined in claim 1 wherein said terminal sections are in the form of loops and wherein a restoring force is presented on said loops when compressed.

10. A holder as defined in claim 9 wherein said at least one aperture engaging sections include C-shaped sections formed by oppositely extending arcuate arms which taper in reduced cross-sectional thickness towards their ends, said arms providing generally uniformly stressed beam sections which allow the outer diameter of said C-shaped sections to conform to the inside diameter of plated holes into which said contacts are inserted.

11. A holder as defined in claim 1 wherein said terminal sections are in the form of loops and wherein a restoring force is presented on said loops when compressed to bias said loops against said component.

12. A holder as defined in claim 1 wherein said at least one aperture engaging sections include C-shaped sections formed by oppositely extending arcuate arms which taper in reduced cross-sectional thickness towards their ends, said arms providing generally uniformly stressed beam sections which allow the outer diameter of said C-shaped sections to conform to the inside diameter of plated holes into which said contacts are inserted.

13. The holder of claim 1, wherein said at least one aperture engaging section and said terminal section integrally form said electrically conductive contact.

14. The holder of claim 11, wherein said loops are open loops.

15. The holder as defined in claim 1, wherein said terminal sections do not overlie the electrical component.

16. A holder for holding an electrical component having terminals on ends thereof, said holder being engageable with a printed circuit board having plated through-holes formed therein, said holder comprising:

an insulated body to receive the electrical component,

at least two laterally spaced electrically conductive contacts accommodated by said body, each of said contacts including;

at least one aperture engaging section extending beyond a surface of said body to frictionally engage with a respective plated through-hole in the printed circuit board to form a solderless electrical and mechanical connection therewith and

a resilient terminal section to contact a respective terminal of the component and retain the component received by said body, said terminal sections are in the form of open loops and a restoring force is presented on said loops when compressed to bias said loops against said component,

wherein said at least one aperture engaging section includes C-shaped sections formed by oppositely extending arcuate arms which taper in reduced cross-sectional thickness towards their ends, said arms providing generally uniformly stressed beam sections which allow the outer diameter of said C-shaped sections to conform to an inside diameter of a respective one of said plated through-holes into which said aperture engaging ends are inserted.

17. A holder as defined in claim 16 wherein said body is formed of plastic material.

18. A holder as defined in claim 16, wherein said terminal sections are in the form of open loops and wherein a restoring force is presented on said loops when compressed to bias said loops against said component.

19. A holder as defined in claim 16, wherein said terminal sections are in the form of loops and wherein a restoring force is presented on said loops when compressed.

20. A holder as defined in claim 16, wherein said body has an elongate recess provided in an upper surface thereof to receive said component.

21. The holder of claim 16, wherein said at least one aperture engaging section and said terminal section integrally form said electrically conductive contact.

22. The holder of claim 16, wherein said loops are open loops.

23. The holder as defined in claim 16, wherein said terminal sections do not overlie the electrical component.

24. A holder for holding an electrical component having terminals on ends thereof, said holder being engageable with a printed circuit board having plated through-holes formed therein, said holder comprising:

an insulated body to receive the electrical component,

at least two laterally spaced electrically conductive contacts accommodated by said body, each of said contacts including;

at least one aperture engaging section extending beyond a surface of said body to frictionally engage with a respective plated through-hole in the printed circuit board to form a solderless electrical and mechanical connection therewith and

a resilient terminal section to contact a respective terminal of the component;

wherein said terminal sections are in the form of loops and wherein a restoring force is presented on said loops when compressed.

25. A holder as defined in claim 24, wherein said terminal sections are in the form of open loops and wherein a restoring force is presented on said loops when compressed to bias said loops against said component.
