Abstract

In accordance with the present invention, an electrical connector 20 has a dielectric housing for receiving at least one coaxial contact 60. The housing has at least one coaxial contact receiving passage 48 and a pair of tines 50 extending angularly toward the profile of each other into the profile of the passage 48. A coaxial contact 60 is received and secured in the passage 48. The coaxial contact 60 has an electrically conductive shell 72 with an electrically isolated concentric center contact 66 therein. The shell 72 has a surface 88 facing rearwardly of the contact 60. The surface 88 is adapted to engage ends 56 of the tines 50 to releasably secure the coaxial contact 60 in the passage 48. Alternate embodiment plug and receptacle contacts are disclosed for power applications.

Claims

1. An electrical connector, comprising:

an insulative first housing member for receiving at least one coaxial contact, said first housing member having a forward face, a coaxial contact receiving face, and at least one coaxial contact receiving passage extending therebetween, said first housing member having at least one resiliently deflectable tine extending from the forward face, said at least one tine axially aligned with said at least one coaxial contact receiving passage and extending angularly toward each other into the profile of said passage; and

an insulative second housing member, the second housing member for engaging the first housing member, for receiving at least one coaxial contact and for securing said at least one coaxial contact in the first and second housing members, said second housing member having at least one coaxial contact receiving passage corresponding in location to said at least one coaxial contact receiving passage in said first housing member, whereby a coaxial contact axially received in said at least one coaxial contact receiving passage is secured between the first and second housing members.

2. An electrical connector as recited in claim 1, further comprising electrically conductive shell means surrounding a mating face for shielding the mating face and for engaging shield means of a complementary connector.

3. An electrical connector as recited in claim 1, further comprising flange means having an aperture therein for receiving mounting means to secure the connector to a complementary connector.

4. An electrical connector as recited in claim 1, wherein the tines are integrally molded with said first dielectric housing.

5. An electrical connector as recited in claim 1 wherein the connector comprises four tines.

6. An electrical connector as recited in claim 1, further comprising a coaxial contact received in the coaxial contact receiving passages of said first and second housing members, said coaxial contact having a center contact, dielectric means concentrically encircling the center contact and an electrically conductive shell surrounding said dielectric means, said shell having a surface facing rearwardly of said contact, said surface adapted to engage the end of said at least one tine to releasably secure the coaxial contact in said at least one coaxial contact receiving passage.

7. An electrical connector as recited in claim 6, wherein said surface is annular.

8. An electrical connector as recited in claim 7, further comprising a conical surface extending from the annular surface forwardly to the shell, whereby during insertion of the coaxial contact into the coaxial contact receiving passage, the tines engage the conical surface and flex outwardly until the annular surface passes the ends of said tines whereupon the tines resile inwardly to secure the coaxial contact in said at least one coaxial contact receiving passage of the connector.

9. An electrical connector, comprising:

a dielectric housing for receiving at least one coaxial contact, said housing having at least one coaxial contact receiving passage and at least one tine extending angularly into the profile of said passage;

a coaxial contact received in said at least one coaxial contact receiving passage, said coaxial contact having an electrically conductive shell with an electrically isolated concentric center contact therein, said shell having a surface facing rearwardly of said contact, said surface adapted to engage the end of said at least one tine to releasably secure the coaxial contact in said at least one coaxial contact receiving passage.

10. An electrical connector as recited in claim 9, wherein the tines are integral with said housing.

11. An electrical connector as recited in claim 9, wherein the center contact is a pin contact.

12. An electrical connector as recited in claim 9, wherein the center contact is a receptacle contact.

13. An electrical connector as recited in claim 9, further comprising additional contacts secured in said housing.

14. An electrical connector as recited in claim 9, wherein said surface is annular.

15. An electrical connector as recited in claim 14, further comprising a conical surface extending from the annular surface forwardly to the shell, whereby during insertion of the coaxial contact into the coaxial contact receiving passage the tines engage the conical surface and flex outwardly until the annular surface passes the ends of said tines whereupon the tines resile inwardly to secure the coaxial contact in said at least one coaxial contact receiving passage of the connector.

16. A coax mix connector, comprising:

an insulative housing for receiving at least one coax contact and at least one non-coax contact, said housing having at least one coax contact receiving passage having a pair of tines extending angularly toward each other into the profile of said at least one coax contact receiving passage, said housing having at least one non-coax contact receiving passage having said non-coax contact secured therein; and

a coaxial contact received in said at least one coaxial contact receiving passage, said coaxial contact having an electrically conductive shell with an electrically isolated concentric center contact therein, said shell having a surface facing rearwardly of said contact, said surface adapted to engage ends of said tines to releasably secure the coaxial contact in said at least one coaxial contact receiving passage.

17. An electrical connector as recited in claim 16, wherein the center contact is a pin contact.

18. An electrical connector as recited in claim 16, wherein the center contact is a receptacle contact.

19. An electrical connector, comprising:

a dielectric housing for receiving at least one terminal member, said housing having at least one terminal member receiving passage and at least one tine extending angularly into the profile of said passage;

a terminal member received in said at least one terminal receiving passage, said terminal member having a tubular forward section for mating with a corresponding terminal and a conductor securing section, said tubular section defining a surface facing rearwardly of said contact, said surface positioned along said forward surface and adapted to engage the end of said at least one tine, said conductor securing section adapted to be secured to a conductor, whereby the terminal member is releasably secured in said at least one terminal member receiving passage.

20. An electrical connector as recited in claim 19. wherein the tubular forward section defines a closed end.

21. An electrical connector as recited in claim 19, wherein the tubular forward section defines an open end.

22. An electrical connector as recited in claim 19, wherein the conductor securing section of the terminal member includes at least one crimp tab, the terminal member comprising a power terminal adapted to be terminated to a power electrical conductor by crimping.

23. An electrical connector as recited in claim 19, wherein the tubular forward section is electrically conductive and the terminal member further comprises a center contact, said center contact disposed concentrically in said tubular forward section and isolated therefrom.
