Abstract

An electrical connector contact has a body for receiving a conductor and for receiving a male pin contact. A spring is configured for engaging the pin contact and includes a plurality of spring fingers positioned for forming a bore with the spring fingers bent radially inwardly and configured for securing a pin in engagement with the body. A sleeve is configured for engaging the body to overlie the spring. Indentations are formed in the body at discrete positions around the body and extend radially inwardly into the pin section. The spring includes tongues extending radially inwardly and configured for extending into the indentations for securing the spring with the body.

Claims

1. An electrical connector contact comprising:

a body having a conductor section for receiving a conductor and a pin section for receiving a male pin contact;

a spring configured for engaging the pin section and including a plurality of spring fingers positioned around the pin section for forming a bore, the spring fingers bent radially inwardly and configured for securing a pin in engagement with the pin section of the body;

a sleeve configured for engaging the body to overlie the spring;

the body pin section including at least one indentation formed in the pin section and extending radially into the pin section;

the spring including at least one tongue extending radially inwardly in the spring bore, the at least one tongue configured for extending into the at least one indentation for securing the spring with the body.

2. The electrical connector of claim 1 further comprising a plurality of discrete indentations formed at positions around the pin section and the spring including a plurality of tongues for engaging respective discrete indentations.

3. The electrical connector of claim 1 wherein the spring includes a base section and fingers extending forwardly from the base section, the at least one tongue extending forwardly toward the spring fingers for extending into the at least one indentation.

4. The electrical connector of claim 1 wherein the spring includes a base section and fingers extending forwardly with from the base section, the at least one tongue extending rearwardly with respect to the spring fingers for extending into the at least one indentation.

5. The electrical connector of claim 1 wherein the sleeve is configured for engaging a portion of the spring when it engages the body.

6. The electrical connector of claim 1 wherein the body further includes a first step section positioned rearwardly of the pin section, the sleeve configured for engaging the first step section to overlie the spring.

7. The electrical connector of claim 6 wherein the body further includes a second step section positioned forwardly of the first step section, the second step section having an outer diameter smaller than the outer diameter of the first step section for providing clearance between the sleeve and spring.

8. The electrical connector of claim 1 wherein the spring includes at least one spring finger having an asymmetrical shape with a wider base and more narrow tip.

9. The electrical connector of claim 1 further comprising a collar positioned rearwardly on the body from the pin section, the sleeve engaging the body and abutting against the collar.

10. The electrical connector of claim 1 wherein the sleeve extends over both ends of the spring.

11. An electrical connector contact comprising:

a body having a conductor section for receiving a conductor and a section for receiving a male pin contact;

a spring configured for engaging the body and including a plurality of spring fingers positioned around the body for forming a bore, the spring fingers bent radially inwardly and configured for securing a pin in engagement with the the body;

a sleeve configured for engaging the body to overlie the spring;

the body including a plurality of indentations formed in the body and extending radially inwardly in the body at positions around the body;

the spring including a plurality of tongues extending radially inwardly in the spring and extending forwardly toward the spring fingers for engaging respective indentations for securing the spring with the body.

12. The electrical connector of claim 11 wherein the sleeve is configured for engaging a portion of the spring when it engages the body.

13. The electrical connector of claim 11 wherein the sleeve engages at least one of the tongues of the spring for pushing the tongue into a respective indentation.

14. The electrical connector of claim 11 wherein the body further includes a first step section and a second step section having a smaller outer diameter than the outer diameter of the first step section for providing clearance, the sleeve configured for engaging the first step section to secure the sleeve with the body.

15. The electrical connector of claim 11 wherein the spring includes at least one spring finger having an asymmetrical shape with a wider base and more narrow tip.

16. The electrical connector of claim 11 wherein the sleeve extends over both ends of the spring.

17. An electrical connector contact comprising:

a body having a conductor section for receiving a conductor and a section for receiving a male pin contact;

a spring configured for engaging the body and including a plurality of spring fingers positioned around the body for forming a bore, the spring fingers bent radially inwardly and configured for securing a pin in engagement with the body;

a sleeve configured for engaging the body to overlie the spring;

the body pin section including a plurality of discrete apertures formed in the pin section and extending radially inwardly in the body;

the spring including at a plurality of discrete radial elements that are inwardly extending in the spring bore, the radial elements configured for extending into respective discrete apertures for securing the spring with the body.

18. The electrical connector of claim 17 wherein the inwardly extending radial elements are dimples.

19. The electrical connector of claim 17 wherein the body further includes a first step section and a second step section having a smaller outer diameter than the outer diameter of the first step section for providing clearance, the sleeve configured for engaging the first step section to secure the sleeve with the body.

20. The electrical connector of claim 17 wherein the spring includes at least one spring finger having an asymmetrical shape with a wider base and more narrow tip.
