Abstract

A connector is provided to be assembled on a first illumination element and configured to be releasably coupled to a mating connector on a second illumination element. The connector includes a connection element comprising a conductor. The conductor comprises a first end coupled to a cable extending through the connection element, and a second end is releasably connected to an end of a mating conductor of the mating connector. A mounting member is configured to secure the connection element to the first illumination element, and a first gap is defined between an internal surface of the mounting member and the external surface of the connection element. A first sealing element is coupled to the mounting member and the connection element; and a second sealing element is coupled to the mounting member and the cable.

First claim

The invention claimed is:

1. A connector configured to be assembled on a first illumination element and to be releasably coupled to a mating connector on a second illumination element, the connector comprising:
a connection element comprising a conductor, the conductor comprising a first end coupled to a cable extending through the connection element, and a second end releasably connected to an end of a mating conductor of the mating connector;
a mounting member configured to secure the connection element to the first illumination element, wherein, a first gap is defined between an internal surface of the mounting member and the external surface of the connection element;
a first sealing element coupled to the mounting member and the connection element, and configured to seal the first gap around a first longitudinal end of the mounting member;
a second sealing element coupled to the mounting member and the cable, and configured to seal a second gap between a second longitudinal end of the mounting member and the cable; and
wherein an inner cavity is formed among the mounting member, the connection element, the first sealing element and the second sealing element, and at least a part of the cable is accommodated in the inner cavity.

2. The connector according to claim 1 , further comprising a coupler secured to the connection element and configured to be releasably coupled to a mating connection element of the mating connector.

3. The connector according to claim 1 , wherein the first gap between the internal surface of the mounting member and the external surface of the connection element is from about 0.5 millimeters to about 10 millimeters in a radial direction.

4. The connector according to claim 1 , wherein the connector element is floatably connected with the first illumination element.

5. The connector according to claim 4 , wherein the connector is enabled to rotate about ±20 degree relative to the first illumination element.

6. The connector according to claim 1 , wherein the first sealing element is made of a material selected from silicone and rubber.

7. The connector according to claim 1 , wherein the mounting member comprises a substantially hollow cylinder and a securing element coupled to one end of the substantially hollow cylinder, and the securing element is configured to fix the connection element to the first illumination element.

8. The connector according to claim 7 , wherein the first sealing element is coupled to the securing element and the connection element, and the second sealing element is coupled to the substantially hollow cylinder and the cable.

9. The connector according to claim 1 , wherein the second sealing element is cured on the cable and is coupled to the mounting member via interference fit.

10. The connector according to claim 1 , further comprising a glue layer between the second sealing element and the mounting member.

11. A connector assembly comprising a first connector configured to be assembled on a first illumination element and a mating connector configured to be assembled on a second illumination element and to be releasably coupled to the first connector, wherein,
the first connector comprises:
a connection element comprising a conductor, the conductor comprising a first end coupled to a cable extending through the connection element, and a second end releasably connected to an end of a mating conductor of the mating connector;
a mounting member configured to secure the connection element to the first illumination element, wherein, a first gap is defined between an internal surface of the mounting member and the external surface of the connection element;
a first sealing element coupled to the mounting member and the connection element, and configured to seal the first gap around a first longitudinal end of the mounting member;
a second sealing element coupled to the mounting member and the cable, and configured to seal a second gap between a second longitudinal end of the mounting member and the cable; and
wherein an inner cavity is formed among the mounting member, the connection element, the first sealing element and the second sealing element, and at least a part of the cable is accommodated in the inner cavity; and

the mating connector comprises:
a mating connection element having the mating conductor accommodated therein; and
a mating mounting member coupled between the second illumination element and the mating connection element and configured to secure the mating connection element to the second illumination element.

12. A lighting system comprising at least two illumination elements, at least one longitudinal end of the illumination element coupled with a first connector for engaging a mating connector on a power source or another illumination element, wherein the first connector comprises:
a connection element comprising a conductor, the conductor comprising a first end coupled to a cable extending through the connection element, and a second end releasably connected to an end of a mating conductor of the mating connector;
a mounting member configured to secure the connection element to the illumination element, wherein, a first gap is defined between an internal surface of the mounting member and the external surface of the connection element;
a first sealing element coupled to the mounting member and the connection element, and configured to seal the first gap around a first longitudinal end of the mounting member;
a second sealing element coupled to the mounting member and the cable, and configured to seal a second gap between a second longitudinal end of the mounting member and the cable; and
wherein an inner cavity is formed among the mounting member, the connection element, the first sealing element and the second sealing element, and at least a part of the cable is accommodated in the inner cavity.

13. The lighting system according to claim 12 , wherein the illumination element is a batten or a light tube, and the length of the illumination element is from about 2 feet to about 8 feet.
