Benefits of technology

[0007] One advantage of the conduit coupling assembly described herein resides in its ability to securely connect two lengths of conduit coaxially.
[0008] Another advantage of the embodiments of the invention described herein is found in that it offers a conduit joint which may resist twisting and / or separation of the coupled conduit sections.
[0009] A further advantage of the coupling assembly described herein is found in that it may be provided as an integral part of the conduit. For example, the coupling assembly components may be preattached to the conduit sections prior to shipping the conduit sections to the job site, e.g., during manufacture, at a centralized location, etc. In this manner, manufacturing costs, installation time, and / or inventory concerns associated with maintaining separate inventories of conduit sections and couplers may be reduced.
[0010] Yet another advantage of the coupling assembly embodiments herein is the ease of which a connection between conduit sections may be assembled and disassembled.

Problems solved by technology

Maintaining inventory of and installing the individual connector parts takes time and costs money.

Embodiment Construction

[0019] With reference to the drawing figures, there appears a conduit joint construction 10 (FIG. 1) according to a first embodiment and a conduit joint construction 11 (FIG. 3) for connecting two conduit sections 12, 14 in coaxial, end-to-end fashion. The conduit 12 has at least one receiving end 18. The receiving end 18 is defined by a swaged or bell portion 20. The bell portion 20 has an enlarged diameter with respect to the conduit 14 is designed to receive a connector sleeve 22. The conduit is preferably electrical metallic tubing and may be formed of steel, aluminum or aluminum alloy, or other metal or metal alloy. Other conduit materials are also contemplated, such as PCV and other plastics.

[0020] The connector sleeve 22 has an externally threaded end 24 and an insertion end 26. Furthermore, the connector sleeve 22 defines an axial channel or bore having an internal diameter sized to receive an end of the second conduit 14. The insertion end 26 of the connector sleeve 22 can...

Abstract

The present disclosure relates to a connector sleeve for joining conduit. The disclosure also relates to a joint construction, coupling assembly for joining conduit. The disclosure further relates to a method for joining conduit using a coupling assembly.

Description

FIELD OF THE INVENTION [0001] The present disclosure relates to a joint construction for conduit, a coupling assembly for joining conduit, a connector sleeve for joining conduit, and to a method for joining conduit using a coupling assembly. It finds particular application in conjunction with electrical metallic tubing and will be described herein primarily by way of reference thereto; however, it will be appreciated that the invention finds utility in conjunction with all manner of conduits, including pipes, tubes, ducts, and the like. BACKGROUND OF THE INVENTION [0002] Electrical metallic tubing (EMT) is thin-walled tubing used to contain and protect electrical wires. EMT is commonly used in warehouses, gymnasiums, factories, and the like. Such conduit is traditionally manufactured in ten (10) foot lengths. The conduit sections can be connected end-to-end for use in applications requiring longer sections. Conduit connectors and conduit coupling assemblies are well known in the art...
