Abstract

Coupling system housings including a receptacle housing with a domed protective door and a male coupler housing that may be used to actuate the receptacle housing door are disclosed. The receptacle housing may be mounted in a receiving structure. The receptacle housing is configured with a dome-shaped door that conceals and protects the connectors of an assembled receptacle when in the closed position. The receptacle housing also includes a biasing mechanism that urges the door to a closed position and maintains the door in its closed position when a male coupler is not mated to the receptacle. The male coupler housing is configured with an ergonomic handle suitable for one handed operation of the male coupler. The male coupler housing may be used to actuate the receptacle housing door during insertion and mating of and assembled male coupler to an assembled receptacle.

Claims

1. A receptacle housing comprising:

a bezel portion comprising an opening configured to receive a male coupler;

a coupler portion connected to the bezel portion and including a coupler platform defining one or more connector openings and also is configured to hold one or more socket contacts, the one or more connector openings having a first open end oriented towards the opening and a second open end, the one or more connector openings configured to facilitate electrical connection of one or more conductive contacts of the male coupler that pass through the one or more connector openings to connect to the one or more socket contacts;

a door moveably connected to the receptacle housing, movable between an open position and a closed position, and configured to conceal the opening in the closed position; and

a door control assembly connected to the door and to the receptacle housing and configured to move the door into the closed position.

2. The receptacle housing of claim 1, wherein the door control assembly is a door biasing assembly configured to automatically bias the door into the closed position.

3. The receptacle housing of claim 1, wherein the door includes rails located on opposite edges of the door that insert into channels of the receptacle housing to guide a sliding operation of the door between the open position and the closed position.

4. The receptacle housing of claim 1, wherein the door control assembly includes a constant force spring and a pulley, the constant force spring and the pulley being configured to automatically guide the door into the closed position.

5. The receptacle housing of claim 1, wherein the door is pivotably connected to the receptacle housing.

6. The receptacle housing of claim 2, wherein the door biasing assembly includes a torsion spring.

7. The receptacle housing of claim 1, wherein the door includes a dome-shaped portion.

8. The receptacle housing of claim 1, further comprising substantially parallel channels configured to slide along opposite edges of the door.

9. The receptacle housing of claim 1, wherein the door includes a door pull at a bottom edge of the door for engaging a portion of a mating end of the male coupler.

10. The receptacle housing of claim 1, wherein the bezel portion comprises an outer surface of the bezel portion that is raised at a peripheral edge relative to a surrounding surface in which the receptacle housing is mounted.

11. The receptacle housing of claim 10, wherein the bezel portion further comprises a runway configured to receive a mating end of the male coupler and guide the mating end of the male coupler from an unaligned position outside of a peripheral edge of the bezel portion to an aligned position at the opening, wherein the runway has a recessed surface that is substantially flush with the surrounding surface.

12. A coupling system comprising:

a male coupler housing having;

a shell including;

a body portion having;

a tail end,

a mating end, and

a mating portion positioned proximate to the mating end and having an opening for connecting a conductive contact of a male coupler to a female coupler, and

a housing coupler platform for the male coupler, the housing coupler platform being secured to the mating portion; and

a female coupler housing having;

a bezel portion comprising an opening configured to receive the male coupler,

a coupler portion connected to the bezel portion and including a coupler platform defining one or more connector openings and also is configured to hold one or more socket contacts, the one or more connector openings having a first open end oriented towards the opening and a second open end the one or more connector openings configured to facilitate electrical connection of one or more conductive contacts of the male coupler that pass through the one or more connector openings to connect to the one or more socket contacts,

a door moveably connected to the female coupler housing, movable between an open position and a closed position, and configured to conceal the opening in the closed position, and

a door control assembly connected to the door and to the female coupler housing and configured to move the door into the closed position.

13. The coupling system of claim 12, wherein the door control assembly is configured to automatically place the door in the closed position when the male coupler is disconnected from the female coupler.

14. The coupling system of claim 12, wherein the door is connected to the female coupler housing, and the door control assembly is a door biasing assembly configured to bias the door into the closed position.

15. The coupling system of claim 12, wherein the door control assembly includes a spring configured to expand in response to opening of the door and compress to place the door in the closed position in response to the male coupler being removed away from the female coupler.

16. The coupling system of claim 12, wherein the female coupler housing is a female coupler housing, and the door comprises a dome-shaped portion for enhancing structural strength of the female coupler housing and resistance to entrance of environmental contaminants.

17. The coupling system of claim 12, wherein the bezel portion further comprises a runway configured to receive a mating end of the male coupler and to guide the mating end of the male coupler from an unaligned position outside of a peripheral edge of the bezel portion to an aligned position at the opening of the bezel portion, wherein the runway has a recessed surface that is substantially flush with the surrounding surface.
