Abstract

An electrical contact (10) with a receptacle section (20) having a cantilever beam (32), which beam is spring biased by a spring (40). The location of the spring (40) is controlled by spring locking sections (46,47,48) formed thereon, and by complementary locking structures (26,27,28) of receptacle (20) which register with the spring locking sections (46,47,48).

Claims

1. An electrical contact comprising:

(a) a receptacle section, said receptacle section comprises, opposed wall sections, and respective apertures formed in said opposed wall sections, said receptacle section including a cantilever beam between said opposed wall section, and a spring receiving opening facing one side of the receptacle section;

(b) a spring disposed in said receptacle section and insertable through said spring receiving opening behind said cantilever beam, said spring comprises locking sections for locking registration with respective said apertures;

(c) said locking sections being wider than opposed wall sections to press on said wall sections as said spring is inserted though said spring receiving opening, thereby deflecting the wall sections; and

(d) said locking sections being received within said apertures so that said wall sections resile back to generally their original positions after the locking sections are snapped into respective said apertures.

2. The electrical contact of claim 1 wherein said locking sections comprise slanted tabs protruding from edges of said spring, said slanted tabs being slanted to deflect said wall sections as spring is inserted through said spring receiving opening.

3. The electrical contact of claim 2 wherein said slanted tabs are slanted to engage respective apertures to prevent withdrawal of said spring through said spring receiving opening.

4. The electrical contact of claim 3 wherein said wall sections include front and rear surfaces facing said one side of said spring receiving opening for engaging said spring in front of and to the rear of said slanted tabs to position said spring in said receptacle section.

5. The electrical contact of claim 4 wherein said front and rear surfaces are disposed to position said spring in a canted configuration in said receptacle section.

6. The electrical contact of claim 5 wherein said front surfaces comprises a tabs formed inwardly from said wall sections.

7. The electrical contact of claim 6 wherein said rear surfaces comprise recesses for receiving rear tabs on said spring.

8. The electrical contact of claim 1 wherein said spring comprises a reversely bent member having a beam joined to a body by a bend section.

9. The electrical contact of claim 1 wherein said spring comprises a stainless steel spring.

10. The electrical contact of claim 8 wherein said locking sections are located on said spring body section with said beam section being free to deflect relative to said wall sections.

11. The electrical contact of claim 1 wherein said receptacle section comprises a deflectable cantilever beam, said spring being located between said opening and said cantilever beam with said spring section engaging said cantilever beam so that deflection of said cantilever beam also requires deflection of said spring.

12. The electrical contact of claim 11 wherein said cantilever beam comprises an extension of said receptacle section, and said spring if formed from a material having different spring characteristics than the material from which said cantilever beam is formed.

13. The electrical contact of claim 11 wherein a free end of said cantilever beam is located adjacent to the front of said receptacle section, said receptacle section including a retaining section engaging the free end of said cantilever beam when said cantilever beam is undeflected.

14. The electrical contact of claim 11 wherein at least one of said wall sections includes an overstress member, said cantilever beam engaging said overstress member to prevent excessive deflection of said cantilever beam, said overstress member also engaging said spring to position said spring in said receptacle section.

15. An electrical contact comprising:

(a) a receptacle section, said receptacle section comprises a spring receiving opening between opposed wall sections;

(b) said opposed wall sections each comprise respective first, second, and third wall locking sections for receiving respective portions of a spring;

(c) a spring disposed in said receptacle section, said spring having complementary first, second, and third spring locking sections on opposed edges of said spring which register with respective first, second and third wall locking sections for positioning the spring in said receptacle section adjacent said spring receiving opening.

16. The electrical contact of claim 15, wherein said receptacle section comprises a cantilever beam therein, overstress of said cantilever beam being prevented by one of said wall locking sections.

17. The electrical contact of claim 15, wherein one of said wall locking sections comprises an edge section, and said one of said spring locking sections is biased against said edge section.

18. The electrical contact of claim 15, wherein said spring is located at a canted orientation relative to said receptacle section by registration between said wall locking sections and said spring locking sections.

19. An electrical contact comprising:

(a) a receptacle section, said receptacle section comprises, opposed wall sections, and respective apertures formed in said opposed wall sections, and a spring receiving opening facing one side of the receptacle section;

(b) a spring disposed in said receptacle section and insertable through said spring receiving opening, said spring comprises locking sections for locking registration with respective said apertures, said spring being deflectable when a mating electrical contact is inserted into said receptacle section;

(c) said locking sections being wider than opposed wall sections to press on said wall sections as said spring is inserted though said spring receiving opening, thereby deflecting the wall sections; and

(d) said locking sections being received within said so that said wall sections resile back to generally their original positions after the locking sections are snapped into respective said apertures.
