Description Wire ~arness Assembly with Routing 81eeve Technical Field This invention relates to electrical wiring and more particularly to automobile wiring harnesses.
B~c~ground of t~- I3~nt~on In automobiles, the components of the various electrical-electronic systems are electrically interconnected via electrical leads or wires. These leads are ~sually grouped together or bundled with tape or the like to form what is commonly termed a wire harness. Generally, a wire harness also includes connector hardware for connection to the various automobile systems and mounting hardware for securing the harness to the automobile body. A wire harness may be quite bulXy and unwieldy depending on the number and complexity of the respective electrical-electronic systems.
During assembly, the wire harness is routed along a predetermined wiring path in the automobile body which may include relatively small passageways such as opening through structural mPmhers. For example, a main wiring harness must be routed through an aperture in the fire wall between the ;
engine compartment and the car interior. To facilitate routing of the harness, it is known to enclose a portion of the wire harness in a sheath of heat-shrink material. The heat-shrink sheathing tends to compress the electrical wires and connector ~-hardware into a more defined compact form which .-. , . : . .- . - . . ..

w092/09089 2 0 7 ~ 8 8 7 PCT/US91/08221 facilitates handling. The sheathing also provides protection for the wire harness during routing in that it prevents the connector hardware from hanging up and chafing of the wires.
once the wire harness has been routed as required, the plastic sheathing must be completely removed. Various prior techniques for removal of the sheathing have proven to be unsatisfactory.
Cutting the sheathing with a knife or other sharp instrument is particularly undesirable because of the probability of damage to the electrical leads.
Perforations in the sheathing to facilitate manual ripping also have not proved satisfactory. During installation, the sheathing tends to chafe or tear slightly as the wire harness is routed through tight passageways, etc. These tears represent weak spots in the sheathing which will prevent the sheathing from ripping cleanly during the removal process -~
thereby necessitating numerous attempts to remove it resulting in frustration to the worker and a number of small pieces of sheathing material for discard.
Often times, the worker will simply give up and will attempt to cut the sheathing from the wire harness with a knife. -8~mmary of the Invention It is an object of the present invention to provide a new and improved wire harness assembly with routing sheathing that that is easily and quickly removable after installation.
It is further object of the invention to --provide such a sheathing which is removable in -largely one piece.

Yet another object of the invention is to provide such a sheathing which is cost efficient to manufacture and labor efficient in use.

Accordingly, it has been found that the foregoing and related objects are attained and the disadvantages of the prior art are overcome in a wire harness assembly comprising a plurality of electrical leads disposed in a bundle, a sheathing formed around the bundle to facilitate routing within the automobile and tear strip means for separating the sheathing longitudinally along the bundle for removal of the sheathing. In a preferred embodiment, the sheathing is a sleeve of thermoplastic heat-shrink material and the tear strip means is a length of tape affixed to the inside surface of the sleeve so as to permit the tape to rip through the sleeve upon the application of sufficient tension on the tape. Accordingly, after installation of the wire harness, the sleeve is ripped longitudinally end-to-end by the tape for one piece removal of the plastic material from the wire harness. In another embodiment, the thermoplastic material includes an additive to enhance the slip characteristics of the exterior surface of the sheathing to facilitate routing through small spaces.

Best Mode for Carrying Out tho Invention Although specific forms of the presQnt invention have been selected for illustration in the drawings, and the following description is drawn in specific terms for the purpose of describing these forms of the invention, the description is not intended to limit the scope of the invention which is defined in the appended claims.
Referring to Fig. l, a wire harness assembly according to the present invention is illustrated in the form of a wire harness configured to extend through the fire wall between the interior and the engine compartment of an automobile. A large grommet 12 seals the fire wall opening after installation so that the wire harness section 14 -forward of the grommet 12 will be routed within the engine compartment forward of the fire wall while the wire harness saction 16 will be routed within the interior aft of the fire wall. -The electrical leads of harness section 16 are bundled together in various separate groups, for example, group 18, 20, 22 by cloth electrical tape generally known as friction tape. The wire groups .. . . .
, V092/09089 2 ~ 7 1 ~ 8 7 PCT/~;S91/08221 ;,P 5 terminate in various connectors 24, 26, 28 respectively. The connectors vary structurally depending upon the particular electrical-electronic system. The electrical leads of the forward section 14 are separated in groups with corrugated conduit 26. The electrical leads of section 14 also terminate in a number of different connectors such as connector 2~. The wiring harness as thus described is known in the art and need not be described in greater detail ~or purposes of the present invention.
Sh~athing in the form ~f heat-shrink sleeve 30 is formed about a po~tion of the forward section 14 to facilitate routing of the forward section 14 such as through the fire wall opening. The sheathing includes a tear strip assembly for manually ripping the sheathing longitudinally end-to-end.
ReSerring to Fig. 2, the sleeve 30 is shown in detail prior to being heat formed about the wire harness section 14. Sleeve 30 is a tubular sleeve of heat-recoverable or heat-shrink material such as a thermoplastic resin. The sleeve material includes an additive to enhance the slip characteristics of -the sleeve so that the exterior of the sheathing will be more slippery to facilitate routing in tight spaces. In the illustrated embodiment, the sleeve 30 is comprised of a polyvinyl chloride sold under the trade name REYNOLON 2016 (200 gage) sold by the Reynolds Netals Company and includes a plasticizer in sufficient quantity to enhance the slip characteristics and resiliency of the sheathing. An acceptable plasticizer is epoxidized soybean oil.
Wax may also be added for increased slip. Other .
. ~ . . . .
.: - ; : i. , . . : . . , wos2/osoxs ~ 7 i g 8 7 PCT/US91/08221 additives known in the art to enhance slip may also be acceptable.
The tear strip assembly comprises a length of vinyl tape 32 affixed to the interior surface 34 of the sleeve. The tape strip 32 is disposed longitudinally along the sleeve from end-to-end.
The tape strip 32 extends beyond each end of the sleeve 30 and is folded back on itself and affixed to the outer surface 36 of the sleeve as best seen in Fig. 3. The folded back portion 38 of the tape 32 forms a tab for gripping the tape to apply manual tension ~or ripping the sleeve. In the illustrated embodiment, the sleeve 30 is approximately 850 mm in length with a flat width of 140 mm. The tape is l9 mm wide with 60 mm to 120 mm excess at each end of the sleeve and is folded back on itself so that the tape overlaps onto the exterior surface of the sleeve with a minimum of 6 mm. Each end of the sleeve 30 contains a longitudinal slit 40 adjacent each longitudinal side 42, 44 of the tape 32. The slits 40 are preferably less than the amount of overlap of tape 32 on the outer surface 36 of the sleeve. As disposed on the sleeve 30, tape strip 32 forms a ripping element for ripping through the sleeve 30 upon applying sufficient tension.
Re~erring back to Fig. l, the sleeve 30 is shown in heat-recovered state forming a sheath about -a portion of the forward section 16 of the wire harness. As can be seen, the tabs 38 extend freely beyond the sheathing for convenient access. After the wire harness is properly routed within the automobile body, the installer simply applies manual tension to either tab 38 sufficient to rip open the ~'092/09089 ~ 8 7 PCT/US91/08221 sheathing longitudinally end-to-end for easy removal of the sheathing in one piece.
Referring to Fig. 4 wherein liXe numerals are used to identify like or similar parts, an alternate embodiment is shown identified as sleeve 46. Sleeve 46 differs from sleeve 30 in that the strip of tape 32 is cloth electrical tape and sleeve 46 contains a perforation path 50 extending longitudinally end-to-end adjacent the longitudinal side 48 of the tape strip 32. A preferred perforation pattern comprises 33% cut and 67% land. The perforations facilitate the cloth tape in ripping apart the plastic sheathing. Additionally, slits are not utilized in the sleeve 46 adjacent the tape strip 32 as in the embodiment of Fig. 2. The cloth tape may be preferable in certain manufacturing arrangements because of ease of assembly to the sleeve.
Additionally, other types of tear strip assemblies and ripping elements may also be acceptable.
As can be seen, a wire harness assembly has been described with a routing sheathing that is easily and quickly removable in largely one piece after installation of the harness. The sheathlng facilitates routing through small spaces and is cost efficient to manufacture and labor efficient in use.
As will be apparent to persons skilled in the art, various modifications and adaptations of the structure above described will become readily apparent without departure from the spirit and scope 3~ of the invention, the scope of which is defined in the appended claims.
