Abstract

A lighting receptacle assembly includes a receptacle assembly housing having a base and a head with a cavity. The head has an upper surface defining a mating interface for mating with a sensor connector and a seal configured to be sealed against the fixture housing. An index mounting ring is coupled to the fixture housing from an interior of the fixture housing and includes indexing features interfacing with housing indexing features. A spring holder plate is coupled to the head and holds a spring biasing the receptacle assembly housing in a holding direction toward the index mounting ring to engage the housing indexing features and the indexing features.

First claim

What is claimed is:

1. A lighting receptacle assembly for mounting to a fixture housing of a light fixture and for mating with a sensor connector having a photocontrol component, the lighting receptacle assembly comprising:
a receptacle assembly housing including a base and a head extending from the base, the head having a cavity, the base including contact channels holding receptacle contacts, the head having an upper surface defining a mating interface for mating with the sensor connector, the head located exterior of the fixture housing, the head having at least one housing indexing feature extending into the cavity, the receptacle assembly housing including a seal configured to be sealed against the fixture housing;
an index mounting ring received in the cavity, the index mounting ring having an opening receiving the base of the receptacle assembly housing, the index mounting ring including at least one indexing feature configured to interface with the at least one housing indexing feature to rotatably fix a position of the receptacle assembly housing relative to the index mounting ring, the index mounting ring including a mounting post configured to be mounted to the fixture housing from an interior of the fixture housing to secure the index mounting ring to the fixture housing; and
a spring holder plate received in the cavity and coupled to the head, the spring holder plate holding a spring between the spring holder plate and the index mounting ring, the spring holder plate and the spring biasing the receptacle assembly housing in a holding direction toward the index mounting ring to engage the at least one housing indexing feature and the at least one indexing feature.

2. The lighting receptacle assembly of claim 1 , wherein the mounting post faces the fixture housing at a bottom of the lighting receptacle assembly to receive a mounting fastener from the interior of the fixture.

3. The lighting receptacle assembly of claim 1 , wherein the mounting post passes through the spring holder plate to interface with the fixture housing, the spring holder plate being movable along the mounting post to compress the spring.

4. The lighting receptacle assembly of claim 1 , wherein the index mounting ring includes a locating post extending from the bottom of the index mounting ring, the locating post extending through the spring holder plate to interface with the fixture housing, the spring holder plate movable along the locating post to compress the spring.

5. The lighting receptacle assembly of claim 1 , wherein the head includes a latch extending into the cavity, the latch engaging the spring holder plate to latchably secure the spring holder plate to the receptacle assembly housing, the spring holder plate being movable with the receptacle assembly housing to an extended position, the spring being compressed between the spring holder plate and the index mounting ring in the extended position, the at least one housing indexing feature being disengaged from the at least one indexing feature to allow rotation of the receptacle assembly housing relative to the index mounting ring to change an indexed position of the receptacle assembly housing.

6. The lighting receptacle assembly of claim 5 , wherein the receptacle assembly housing rotates relative to the spring holder plate to change the indexed position of the receptacle assembly housing.

7. The lighting receptacle assembly of claim 1 , wherein the receptacle assembly housing includes a housing rotation stop, the index mounting ring including a rotation stop, the housing rotation stop engaging the rotation stop to limit rotation of the receptacle assembly housing relative to the index mounting ring to less than 360°.

8. The lighting receptacle assembly of claim 1 , wherein the head of the receptacle assembly housing includes a lower skirt having a bottom surface facing the fixture housing, the seal provided at the bottom of the lower skirt.

9. The lighting receptacle assembly of claim 8 , wherein the lower skirt includes a pocket elevated above the bottom surface configured to receive an embodiment of the fixture housing at an upper surface of the fixture housing.

10. The lighting receptacle assembly of claim 1 , wherein the spring holder plate includes vertical stops extending from the spring holder plate to engage the index mounting ring and limit vertical movement of the spring holder plate relative to the index mounting ring.

11. The lighting receptacle assembly of claim 1 , wherein the mounting post is a first mounting post extending from a lower surface of the index mounting ring, the index mounting ring including a second mounting post extending from the lower surface of the index mounting ring, mounting fasteners being secured to the first and second mounting posts from the interior of the fixture housing to secure the index mounting ring to the fixture housing.

12. The lighting receptacle assembly of claim 1 , wherein the seal is co-molded with the receptacle assembly housing.

13. The lighting receptacle assembly of claim 1 , wherein the spring is a coil spring.

14. The lighting receptacle assembly of claim 1 , wherein the spring is a wave spring.

15. A light sensor assembly for mounting to a fixture housing of a light fixture, the light sensor assembly comprising:
a sensor connector including a sensor element for sensing an environmental characteristic exterior of the sensor connector, the sensor connector including sensor contacts at a bottom of the sensor connector; and
a lighting receptacle assembly coupled to the sensor connector and configured to be coupled to the light fixture to control operation of the light fixture, the lighting receptacle assembly comprising:
a receptacle assembly housing including a base and a head extending from the base, the head having a cavity, the base including contact channels holding receptacle contacts, the head having an upper surface defining a mating interface for mating with the sensor connector, the head located exterior of the fixture housing, the head having at least one housing indexing feature extending into the cavity, the receptacle assembly housing including a seal configured to be sealed against the fixture housing;
an index mounting ring received in the cavity, the index mounting ring having an opening receiving the base of the receptacle assembly housing, the index mounting ring including at least one indexing feature configured to interface with the at least one housing indexing feature to rotatably fix a position of the receptacle assembly housing relative to the index mounting ring, the index mounting ring including a mounting post configured to be mounted to the fixture housing from an interior of the fixture housing to secure the index mounting ring to the fixture housing; and
a spring holder plate received in the cavity and coupled to the head, the spring holder plate holding at least one spring between the spring holder plate and the index mounting ring, the spring holder plate and the springs biasing the receptacle assembly housing in a holding direction toward the index mounting ring to engage the at least one housing indexing feature and the at least one indexing feature.

16. The light sensor assembly of claim 15 , wherein the mounting post faces the fixture housing at a bottom of the lighting receptacle assembly to receive a mounting fastener from the interior of the fixture, the mounting post passing through the spring holder plate to interface with the fixture housing, the spring holder plate being movable along the mounting post to compress the spring.
