Patent number: 10367338Abstract: 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.Type: GrantFiled: March 8, 2017Date of Patent: July 30, 2019Assignee: Thomas & Betts International LLCInventor: Cong Thanh Dinh

Patent number: 10243313Abstract: 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.Type: GrantFiled: June 16, 2016Date of Patent: March 26, 2019Assignee: Thomas & Betts International LLCInventor: Cong Thanh Dinh

Patent number: 10069267Abstract: A method for installing a conduit in a liquid-tight fitting includes inserting a coated gland nut configured for insertion onto a conduit, wherein the gland nut includes an outer surface and internal threads. A grounding ring is placed onto external threads of a tubular fitting body having a coated intermediate portion, such that an inner surface of the grounding ring is conductively coupled to the external threads of the fitting body. The outer surface of the grounding ring includes a ground wire engaging portion projecting therefrom. The internal threads of the gland nut are loosely coupled to the external threads of the fitting body. The grounding ring is rotated to a desired position relative to the fitting body. The gland nut is tightened to the fitting body, such that the coated outer surface of the gland nut and the coated intermediate portion of the fitting body compressingly engage the grounding ring therebetween.Type: GrantFiled: February 12, 2015Date of Patent: September 4, 2018Assignee: Thomas & Betts International LLCInventor: Cong Thanh Dinh
