TECHNICAL FIELD

The present disclosure generally relates to wiring. More particularly, but not exclusively, the present disclosure relates to a wiring harness assembly and a method of making a wiring harness assembly.

BACKGROUND

Wiring is a well-known practice for the installation of electrical wiring for residential, commercial and/or industrial purposes. The wiring process is often complex with many bundles of interconnected wire networks stacked and/or clamped usually and concealed under accessible structures for future replacement, repair and/or maintenance. In many cases wiring installations require wiring harnesses, connectors, splitters and jointers.

A wire may be a single usually cylindrical, flexible strand or rod of metal or a multistrand of braided rods within a protective sleeve. Wire gauges come in various standard sizes, as expressed in terms of a gauge number (i.e diameter size). A wiring harness is an assembly of electrical wires bound together by a durable material such as rubber, vinyl, electrical tape the like. The wires are first cut to the desired length and they may also be printed on with indicia for being identified. The ends of the wires are stripped (by removing portions of the sleeve) to expose the metal (or core) of the wires, which are fitted with any required terminals or connectors The wires are then assembled and interconnected into a harness and bound together. Connectors are fasteners used to make a tight, low-impedance connection between two or more electrical wires. Made of flame-retardant materials, wire connectors prevent wires from contacting other wires or exposed metal surfaces.

Wire harnesses are used in a variety of industries including and without limitation to the automobile industry, the trailer industry, the telecommunications industry, the medical industry, the aviation industry, the marine and off-road industries etc

As such, a variety of single or plural cable and connector type combinations including a variety of different type and number of cable portions along a same trunk or branch can be contemplated within the scope of the present disclosure.

With reference to FIGS. 8A and 8B, the connection between a cable and a connector will be further described in a accordance with a non-restrictive illustrative embodiment of the present disclosure. A cable 400 defines an outer jacket 402 grouping wires 404 therein and defines a terminal end 406 thereof. An enlarged female connecting portion 408 is defined about the terminal end 406 which includes inner mating elements 410 such as threads formed within the inner surface 411 of the female connecting portion 408. A connector 412 includes a main body 414 that provides for arms 416 extending therefrom. An arm 416 houses wires 417 therein and defines a terminal end 418 and defines a male portion 420 including outer mating elements 422 such as threads for mutual interference engagement with threads 410. Accordingly, the male portion 420 is inserted within the female portion 408 such that there is wire-to-wire contact 424 between wires 404 and 417. The female portion 408 defines a rim 426 circumscribing the opening 428 leading to the cable tunnel 430 in which the wires 404 run. This rim 426 is engaged by a shoulder 432 formed at the base of the arm 416 which acts a stopper to the inward movement of the male portion 420.

In an embodiment, the connectors of the disclosure comprise the wire harnessing devices of U.S. patent application Ser. No. 16/983,501. These connectors include an outer housing with main portion and arm or branch portions extending therefrom. The housing houses a wiring harness embedded therein and includes main trunk wires (or wire segments) and branch wires (or wire segments) connected together at connecting points thus defining the wiring harness. The trunk wires (or wire segments) and the branch wires (or wire segments) extend into the arms. The arms define open free ends for allowing electrical (i.e. wire-to-wire) connection to the respective terminal connecting ends for being respectively connected to main trunk wires within main trunk cables and branch wires within branch cables. Thus, the main trunk wires (or wire segments) of the wire harness within the connector have terminal ends that connect to respective terminal end of the main trunk cable and the branch wires (or wire segments) of the wire harness within the connector have terminal ends that connect to branch wires of the branch cables. The connector wire harness thus corresponds to the attachment area 108 and the wire-to-wire connections between the wires (or wire segments) of the connector wire harness and the main trunk cable and branch cables correspond fall within the above-discussed proximal zones of the intersections 128 shown in FIG. 1.

Turning to FIGS. 9, 10A, 10B and 11 various examples of connectors will be described so as to further exemplify the disclosure and not limit the scope thereof.
