Abstract: A compression connector for connecting two wires is disclosed. The compression connector is made of either a single bifurcated connector body or two individual connector components that are slidably coupled and then crimped. As the compression connector is crimped, structural features on the connector components are pushed into a locked state in the two component embodiment. Bifurcated embodiments allow for more than one crimping act on the compression connectors resulting in a more reliable compression connection. The compression connector that results is much more resistant to failure compared to known C-shaped compression connectors.

Abstract: A cable compression die assembly is used in connection with a compression tool for compressing a stranded cable prior to crimping. Upper and lower compression dies each have a semicircular groove to compress the cable. A plurality of extending blocks guides each die into sliding engagement. The stranded cable will be compressed between the upper and lower compression dies to a reduced cable radius. Compressing generally reduces or eliminates air spaces between the stranded cable wire strands. A subsequent crimp connection forms a nearly monolithic structure to maximize current flow between two crimp connected compressed stranded cables.

Abstract: The disclosed invention provides a conduit sleeve with detachable end cap that greatly reduces the complexity of the current system that requires a multiplicity of integral sleeve conduit bodies, styles, fixtures, fittings, connectors, rigid conduits with female threading, and other receiving structures. Now, one conduit sleeve with detachable end cap can be used to protect a threaded conduit end without the need for specialty receiving structures having an integral sleeve. This is accomplished by having a single object performing both roles as conduit sleeve and end cap. The end cap portion can simply be cut or twisted off from the conduit sleeve portion at a convenient time after installation onto a rigid conduit, tube, pipe, or similar structure. The remaining conduit sleeve that is left protects the area of the rigid conduit where conduit threads would have been left exposed since they are not fully threaded into the receiving structure.
