ABSTRACT:
TECHNICAL FIELD
This invention relates generally to protective shielding for automotive electrical wiring that extends out from a splash shield to a flexible plastic axially slit corrugated conduit.
BACKGROUND OF THE INVENTION
Splash shields are well known to provide a degree of protection to electrical wiring in automotive use. Electrical wiring harness bundles enter and exit the splash shield and run through flexible corrugated plastic conduit.
What is desired is an adaptable protective shielding that protects electrical wiring extending from a splash shield to a protective conduit that can run along the splash shield. What is also desired is a protective device that can allow for rotatable adjustment of the conduit along the wall. What is also desired is a protective device that allows differently sized protective conduits to be attached to the splash shield.
SUMMARY OF THE INVENTION
In accordance with one aspect of the invention, a wiring protective dress for electrical wiring extends between a splash shield member and a flexible corrugated tubular conduit. The protective dress includes an elbow member having a passage through which the electrical wiring can extend. The elbow has a first open end and second open end transversely angled with respect to each other. The elbow member has at least one circumferentially extending internal flange in proximity to the first end for engagement with the tubular conduit. The elbow member also has an external groove in proximity to the second end. A collar is fastened about the elbow member groove. The collar in turn engages a slot of said splash shield member. Preferably, one of the elbow member and collar has at least one external longitudinally extending rib for selective engagement to at least one longitudinal extending groove in the other of the elbow member and collar to provide for a discrete rotational angular adjustment of the elbow to the splash shield. Preferably the elbow member has a plurality of longitudinal extending external ribs in proximity to the second end for affixation to grooves in the collar at a selective rotated angle. It is desirable that the elbow has two shell sections connected together by a living hinge and closeable by a complementary latching element on each shell section.
In accordance with another aspect of the invention, the wiring protective dress includes a collar fastenable about the groove in the elbow member. The collar has an axial extending splined fitting for selectively engaging the elbow member in one of a plurality of relative angular positions with the elbow member. The collar has a spaced inner and outer mounting flange, is slideably receivable in a slot of the splash shield, and engages the wall of the splash shield.
In accordance with another aspect of the invention, the wiring protective dress includes the collar having two half sections connected together with a living hinge and closeable about a conduit and lockable by a complementary latching element on each half section. At least one internal circumferentially spanning rib engages with a groove of the conduit to retain attachment with the conduit.
In accordance with another aspect of the invention, a wiring protective assembly includes a splash shield having side walls and at least two slots for electrical harness wiring to pass therethrough. A first collar has spaced inner and outer mounting flanges for being installed in one of the slots. The first collar has at least one internal rib engaging a conduit that extends through said first collar and protrudes in a substantially transverse direction from the splash shield side wall. A second collar has spaced inner and outer mounting flanges for installation in another of the slots. The second collar is fastened about an elbow member. The elbow member has a passage with first and second open ends transversely angled with respect to each other and with the second end received through the collar and into the splash shield. The elbow member has at least one circumferentially extending integral flange in proximity to the first end for engagement with another conduit that is received in the second end. Preferably, the second collar and the elbow member has complementary spline connections to selectively mount to the elbow at one of a plurality of rotated angular positions along one of the side walls of the splash shield.
In this fashion a protective dress becomes quite adaptive for a variety of electrical wiring arrangements and still provides protection to the electrical wiring passing out of the splash shield and into the flexible conduits.
