Abstract

An improved bayonet connector assembly includes a connector nut having a generally cylindrical tubular configuration with a bore extending axially therethrough. In one embodiment the inner surface of the bore includes at least one camming surface extending both circumferentially and axially therein and disposed to impinge upon the corresponding bayonet pin of the mating bayonet connector. A detent window is formed at the inner end of each camming surface to engage and retain the bayonet pin that is driven slidably along the camming surface into the detent window. The end surfaces of the cylindrical nut are annular and continuous, so that the strength of the structure is maximized. Furthermore, the camming surfaces and the detent slots are arranged so that the entire nut may be formed in a single molding operation. In another embodiment, the camming surfaces and detent recesses are formed on the exterior of the female connector, and the bayonet pins extend radially inwardly in the bore of the bayonet nut.

Claims

1. In a bayonet connector assembly having male and female plug components, a bayonet nut secured concentrically and rotatably to one of said components and having means to engage at least one bayonet pin extending outwardly from the other of said components, and a bore extending axially in said nut and having an interior bore surface, the improvement comprising detent means disposed within said bore to releasably secure a bayonet pin, and camming surface means disposed in said interior bore surface to engage a bayonet pin and urge the bayonet pin into said detent means as said male and female components are urged together axially.

2. The bayonet connector assembly of claim 1, wherein said camming means includes at least one camming surface extending in said bore surface from a distal end of said nut to said detent means.

3. The bayonet connector assembly of claim 2, wherein said camming surface extends in smooth and continuous fashion in the axial direction and angularly in the circumferential direction in the bore from said distal end of said nut toward said detent means.

4. The bayonet connector assembly of claim 3, further including an inset portion extending into said bore surface, said inset portion having a proximal edge which defines said camming surface.

5. The bayonet connector assembly of claim 4, wherein said inset portion is provided with a diameter sufficient to pass said bayonet pin therethrough, and said bore is provided with a diameter less than sufficient to pass said bayonet pin therethrough.

6. The bayonet connector assembly of claim 5, wherein said inset includes a further edge extending generally axially in said bore.

7. The bayonet connector assembly of claim 6, wherein said detent means includes a detent window extending generally radially from the exterior of said nut to said bore of said nut.

8. The bayonet connector assembly of claim 7, wherein said detent window includes a first portion extending into said bore at a conjunction with said inset portion.

9. The bayonet connector assembly of claim 8, wherein said detent window includes a second portion extending into said bore at a location not in conjunction with said inset portion.

10. The bayonet connector assembly of claim 9, wherein said second portion of said detent window comprises a detent for releasably retaining a bayonet pin.

11. The bayonet connector assembly of claim 10, wherein said connector includes a plurality of said camming surfaces and a like plurality of said detent windows.

12. The bayonet connector assembly of claim 1, further including a connector body member disposed concentrically to said bayonet nut, and a central passage extending axially through said body member.

13. The bayonet connector assembly of claim 12, further including an optical fiber extending through said central passage of said body member to conduct light between said one component to said other component.

14. A bayonet connector assembly having male and female plug components, one of said components having a plurality of bayonet pins extending therefrom, the other of said components having detent means for releasably securing said bayonet pins and camming surface means for directing said bayonet pins into said detent means, said bayonet pins and camming means being engageable by axial proximation of said two components in mating fashion, wherein said male component includes a bayonet nut secured thereto, said bayonet nut having a bore extending axially therein, said plurality of bayonet pins extending radially inwardly in said bore.

15. The bayonet connector assembly of claim 14, wherein said camming means includes at least one camming surface extending about the outer surface of one of said components.

16. The bayonet connector assembly of claim 15, wherein said camming surface is disposed about said female component and extends from an outer mating end of said female connector to said detent means.

17. The bayonet connector assembly of claim 16, wherein said camming surface extends in smooth and continuous fashion in the axial direction and angularly in the circumferential direction from said outer end of said female component toward said detent means.

18. The bayonet connector assembly of claim 17, further including an inset portion extending into said outer surface, said inset portion having a proximal edge which defines said camming surface.

19. The bayonet connector assembly of claim 17, wherein said inset portion is provided with a diameter sufficiently small to pass said bayonet pin thereby, and said outer surface of said female component is provided with a diameter too large to pass said bayonet pin thereby.

20. The bayonet connector assembly of claim 14, further including a connector body member disposed concentrically to said bayonet nut, and a central passage extending axially through said body member.

21. The bayonet connector assembly of claim 20, further including an optical fiber extending through said central passage of said body member to conduct light between said one component to said other component.

22. The bayonet connector assembly of claim 16, wherein said detent means includes a quartet of detent portions, further including a quartet of camming surfaces, each joined to one of said detent portions.
