Abstract

A coaxial connector assembly includes a plug connector 2 and a mating jack connector 102. The plug connector 2 is a snap-on or quick connect and quick disconnect style connector. The plug connector 2 includes a shell 10 that can be terminated to a coaxial cable outer shield or braid 114. The shell 10 has deflectable spring fingers 12 formed at its mating end with a radially extending lip 16. A collar 30 surrounds the shell 10. The collar 30 is formed by a two housing components 32 that are preferably identical and can be mated together in surrounding relationship to the shield. Spring beams 34, 34A or elastomeric members 34B engage the peripheral lip to urge the collar 30 and the shell 10 toward a neutral position, even though the collar 30 and the shell 10 are relatively axially shiftable to facilitate mating and unmating.

Claims

1. A coaxial connector comprising a female component having a movable first terminal including a deflectable locking member encased in a molded stationary housing;

a male component having a second terminal, said male component being adapted for insertion into said deflectable locking member of said female component, wherein upon insertion of said male component into said deflectable locking member, the first terminal is axially moved to a retracted position within said housing from a first position which prevents deflection of said locking member, and thus prevents insertion and removal of said male component when engaged therein, to said retracted position which permits deflection of said locking member, and thus permits insertion and removal of said male component, and wherein the female component further comprises spring means for biasing the first terminal toward the first position.

2. The coaxial connector of claim 1 wherein the female component comprises a plug connector and the first terminal comprises a plug terminal, and wherein the male component comprises a coaxial jack connector which is matable with said plug connector.

3. The coaxial connector of claim 2 wherein the molded housing comprises two matable housing components which secure together to envelop the first terminal.

4. The coaxial connector of claim 3 wherein the two housing components are identical forming hermaphroditic housing components.

5. The coaxial connector of claim 1 wherein the molded housing includes at least one inwardly projecting arm engaging the deflectable locking member to maintain the deflectable locking member in a generally central location relative to the housing and thus reduce vibration of such member relative to the molded housing.

6. The coaxial connector of claim 1 wherein the spring means extends from the molded housing member and engages a peripheral lip on the first terminal.

7. The coaxial connector of claim 6 wherein the spring means comprises at least one molded spring beam comprising a molded extension of the molded housing extending inwardly toward the first terminal.

8. The coaxial connector of claim 6 wherein the spring means comprises at least one separate member extending between the molded housing and the peripheral lip.

9. The coaxial connector of claim 6 wherein the spring means comprises an elastomeric member joined to the molded housing as part of a two stage molding operation.

10. A coaxial connector comprising a coax terminal shell having a generally cylindrical cross section and an outer collar surrounding the coax terminal shell, the outer collar having a generally cylindrical inner surfaces on which the coax terminal shell is positioned, the outer collar further comprising two separate housing components securable in surrounding relationship to the coax terminal shell in a position to permit movement of the coax terminal shell to a retracted position within the outer collar, wherein the outer collar has a generally rectangular outer periphery.

11. The coaxial connector of claim 10 wherein the two separate housing components are securable in surrounding relationship to only a single coax terminal shell.

12. The coaxial connector of claim 10 wherein the two separate housing components comprise molded members.

13. The coaxial connector of claim 12, wherein the two separate housing components are latched together when in surrounding relationship to the coax terminal shell.

14. The coaxial connector of claim 12 wherein at least one housing component includes an inwardly projecting molded spring beam engaging the coax terminal shell to urge the coax terminal shell relative to the at least one housing component toward a mating end of the coaxial connector.

15. The coaxial connector of claim 14 wherein each housing component includes at least one pair of inwardly projecting molded spring beams, the spring beams forming each pair being slanted toward each other so that the spring beams forming a pair are more widely spaced adjacent where each beam is joined to the outer collar than adjacent opposed distal ends of the spring beams forming a pair of spring beams.

16. The coaxial connector of claim 12 wherein the two separate molded housing components comprise identical hermaphroditic members.

17. The coaxial connector of claim 12 wherein the housing components each include an inwardly projecting arm engaging the coax terminal to center the coax terminal shell relative to the outer collar.

18. The coaxial connector of claim 10 further comprising a pin held in a dielectric sleeve located between the pin and the coax terminal shell.

19. A coaxial connector comprising a snap lock shell attachable to an outer conductor in a coaxial cable and a collar axially shiftable relative to the shell, the snap lock shell including at least one radially deflectable member located on a mating end of the shell and radially extending lip, spaced from the deflectable member, the radially extending lip being trapped between spring means affixed to the collar, the spring means generating a force between the shell and the collar for maintaining the shell and the collar in a relatively neutral position.

20. The coaxial connector of claim 19 wherein the lip has an outer radial dimension at least approximately the same as an outer radial dimension of the at least one deflectable member.

21. The coaxial connector of claim 19 wherein the at least one deflectable member includes an inwardly extending ridge, the ridge comprising means for snap locking the shell to a mating coaxial jack.

22. The coaxial connector of claim 19 wherein the shell includes a crimping mandrel comprising means for attaching the shell to the outer conductor in the coaxial cable, the radial lip being located between the mandrel and the at least one deflectable member.

23. The coaxial connector of claim 19 wherein the spring means engage the lip on opposite sides of the shell.

24. A coaxial connector, matable with a mating coaxial connector, in which the coaxial connector includes a resilient metallic shell matable with a mating metallic member in the mating coaxial connector, to connect outer conductors on coaxial lines attached to the coaxial connector and the mating coaxial connector;

the coaxial connector including a collar surrounding the resilient metallic shell with at least one inwardly projecting anti-vibration arm engaging the metallic shell to comprise means for damping vibration of the resilient metallic shell and to reduce rattle and noise due to such vibrations, said collar comprising two matable, identically formed hermaphroditic components that snap together to envelop the metallic shell.

25. The coaxial connector of claim 24 wherein the collar comprises a molded member.

26. The coaxial connector of claim 25 wherein the anti-vibration arm comprises an extension of the molded member.

27. The coaxial connector of claim 26 wherein the collar comprises a two-part housing, each part of the housing including at least one anti-vibration arm.
