Abstract

A coaxial cable assembly 2 consists of a plug coaxial connector subassembly 4 and a jack coaxial connector subassembly 6. A plug connector 10 and a jack connector 50 are respectively mounted in molded plug and jack housings 20 and 60 respectively. The plug and jack housings 20 and 60 include a latching beam 66 that is attachable to a raised bum 26 on the other connector. The maximum force for disengaging the two subassemblies is greater than the engagement force because the bump includes a sloping forward surface 36 and a steep rear surface 38. When used with connectors 10 and 50 that have equal mating and unmating forces, the total unmating force exceeds the mating force. The latches and the connectors are also positioned so that maximum mating forces of the two separate latching systems do not overlap, thus keeping the total mating force within acceptable limits.

Claims

1. A press-fit type coaxial connector assembly comprising a plug coaxial assembly matable with a jack coaxial assembly, wherein:

the plug coaxial assembly comprises a plug coaxial connector and a molded plug housing comprising first and second plug housing components latched together around the plug coaxial connector, and;

wherein

the plug coaxial connector is latched to the jack coaxial connector when mated and wherein the molded plug housing is separately latched to the molded jack housing when the plug coaxial assembly is mated to the jack coaxial assembly.

2. The coaxial connector assembly of claim 1 wherein the plug coaxial connector is latched to the jack coaxial connector by spring fingers on one of the coaxial connectors received within a peripheral groove on the other of the coaxial connectors.

3. The coaxial connector assembly of claim 2 wherein the spring fingers are surrounded by a collar on one coaxial connector, the collar being received within a recess formed within one of the molded plug and jack housings in which the coaxial connector with the spring fingers is positioned.

4. The coaxial connector assembly of claim 3 wherein the plug coaxial connector includes the collar and wherein a portion of the jack connector protrudes beyond the mating face of the molded jack housing and is received within the collar on the plug connector when the plug coaxial assembly is mated to the jack coaxial assembly.

5. The coaxial connector assembly of claim 1 wherein the plug housing components comprise identical hermaphroditic plug components and the jack housing components comprise identical hermaphroditic jack components.

6. The coaxial connector assembly of claim 1 wherein the molded jack housing and the molded plug housing each include semi-cylindrical surfaces on each respective housing components to form a compartment in which the respective connector is positioned.

7. The coaxial connector assembly of claim 1 wherein each molded housing includes crush pads comprising means for securing connectors in respective housings.

8. The coaxial connector assembly of claim 1 wherein both the plug coaxial connector and the jack coaxial connector include means for attaching the respective connector to a coaxial cable.

9. The coaxial connector assembly of claim 1 wherein one of the molded housings includes spaced apart rails on one side for mounting the coaxial connector assembly on a companion member insertable between the rails.

10. A press-fit type coaxial connector assembly comprising mating plug and jack coaxial connectors, the plug coaxial connector being mounted in a molded plug housing and the jack coaxial connector being mounted in a molded jack housing, the plug housing including a plug latch and the jack housing including a jack latch, the plug latch being matable with the jack latch with an engagement force, the plug latch being unmatable from the jack latch with a disengagement force, the disengagement force being greater than the engagement force so that the plug coaxial connector and the jack coaxial connector can be locked in a mating configuration.

11. The coaxial connector assembly of claim 10 wherein one of the plug latch and the jack latch comprises a deflectable cantilever beam and the other of the plug latch and the jack latch comprise a bump, the deflectable cantilever beam being deflected by the bump as the plug and jack coaxial connectors are mated.

12. The coaxial connector assembly of claim 11, wherein the bump has a forward surface slanted at an acute angle relative to a housing side from which the bump protrudes and the bump has a rear surface extending at a greater angle relative to the side from which the bump protrudes, so that the force required to deflect the deflectable cantilever beam is less as the plug and jack connectors are mated than when the plug and jack connectors are unmated.

13. The coaxial connector assembly of claim 12 wherein the cantilever beam comprises a portion of the molded jack housing and the bump comprises a portion of the molded plug housing.

14. The coaxial connector assembly of claim 10 wherein a connect force for mating the plug and jack coaxial connector is approximately equal to a disconnect force for unmating the plug and jack coaxial connectors.

15. The coaxial connector assembly of claim 14 wherein one of the plug and jack coaxial connectors includes spring figures engagable with and disengagable from a groove of the other of the plug and jack connectors.

16. A coaxial connector assembly comprising a first subassembly matable with a second subassembly, wherein:

the first subassembly comprises a first coaxial connector positioned in a first molded housing, the first coaxial connector including spring fingers, the first molded housing including a first latching member; and

the second subassembly comprises second coaxial connector positioned in a second molded housing, the second coaxial connector including a groove enagable with the spring fingers to form a quick connect-disconnect connection, the second molded housing including a second latching member matable with the first latching member to lock the first and second subassemblies in mating engagement, wherein;

the spring fingers and the groove are positioned relative to the first and second latching members respectively so that a first mating force peak attributable to mating the first coaxial connector to the second coaxial connector occurs prior to a second mating force peak attributable to mating the first latching member to the second latching member so that the first and second mating force peaks do not overlap as the first subassembly is mated to the second subassembly.

17. The coaxial connector assembly of claim 16 wherein the first coaxial connector comprises a plug coaxial connector and the second coaxial connector comprises a jack coaxial connector.

18. The coaxial connector assembly of claim 16 wherein one of the first and second latching members comprises a molded deflectable latching beam and the other of the first and second latching members comprises a raised bump over which the latching beam is deflected as the first subassembly is mated to the second subassembly.

19. The coaxial connector assembly of claim 18 wherein a force for engaging the first and second coaxial connectors is substantially the same as a force for disengaging the first and second coaxial connectors and wherein a force for disengaging the deflectable latching beam from the bump is greater than a force for engaging the deflectable latching beam with the bump so that the deflectable latching beam and the bump comprise means for locking the first and second subassemblies together when the first coaxial connector is mated to the second coaxial connector.

20. A coaxial connector assembly comprising a plug coaxial assembly matable with a jack coaxial assembly, wherein:
