Abstract
A liquid tight connector for connecting non-metallic or metallic conduit to panels or similar devices. The connector is an effort and time saving device that allows connection of conduit to panels without the need to disassemble a portion of the connector and then reassemble again as in prior art devices. The connector allows an installer to simply push a conduit into one end of the connector and push the opposite end of the connector into an aperture in a panel. Liquid tight seals are created between the conduit and the connector and between the connector and the panel. By proper selection of the material of construction, the connector may be built for use with either metallic or non-metallic conduit.
Claims9
A liquid tight connector comprising:
- a tubular body including a central flange having a forward and a rearward wall;
- a ferrule extending from said rearward wall;
- a tubular nose portion extending from said forward wall;
- a washer disposed on said nose portion adjacent said forward wall;
- a ring secured to said nose portion, said ring securing said washer against said forward wall, said ring capable of engaging and securing said nose portion to an aperture in a panel in a manner that said washer is compressed and deformed so that the area between said nose portion and said aperture is filled with said washer thereby creating a liquid-tight seal between said nose portion and said panel;
- a tubular retainer body extending from and secured to said rearward wall, said retainer body concentric with and of a greater diameter than said ferrule, said retainer body including inward directed tangs extending within the inner periphery of said retainer body with the free ends of said tangs oriented toward said rearward wall;
- a conduit-accepting channel defined as the area between said ferrule and said retainer body, said channel capable of accepting a metallic or non-metallic conduit and creating a liquid-tight seal between said channel and said conduit;
- threads on the outer periphery of said tubular nose portion;
- and
- integral tangs extending inwardly from said ring;
- wherein said ring is secured to said nose portion by said integral tangs of said ring extending within said nose portion.

- and
- threads on the outer periphery of said tubular nose portion;
- wherein said ring is secured to said nose portion by said threads of said nose portion and said retainer body is secured to said rearward wall by a tubular retainer body cover, said retainer body cover having a wider diameter than said retainer body, said retainer body cover including interior threads on an end facing said rearward wall of said flange, said rearward wall including a collar having exterior threads to mate with said interior threads on said retainer body cover, said retainer body cover secured to said rearward wall by screwing said cover onto said collar, said retainer body cover including a lip at its opposite end from said rearward wall to hold said retainer body against said rearward wall.
