Abstract
The utility model discloses a protecting bush of an automobile wire harness via hole. The protecting bush comprises a central hole, an inner flange, an outer flange and a groove disposed between the inner flange and the outer flange, and the projection of the inner flange along the central axis direction of the protecting bush uniformly drops into the projection of the outer flange along the central axis direction of the protecting bush. When the protecting bush is assembled, the inner flange of a smaller structure is inserted into car frame holes, and the assembly is more convenient.
Description
Technical field
The utility model relates to cable harness protection sleeve technical field, is specifically related to a kind of sheath of automotive wire bundle via hole.
Background technology
Automotive wire bundle when mounted, often can be bored a hole vehicle frame, but due to machined burrs and the wedge angle in vehicle frame aperture, directly wire harness is penetrated in vehicle frame hole and can cause damage to wire harness, even causes wire harness short circuit or opens circuit.Common technical scheme is to increase rubber sheath at wire harness passing-hole place, avoids the damage of wire harness, but current existing rubber sheath structure is installed inconvenience, and assembling is produced in impact.
Utility model content
The utility model provides a kind of sheath of automotive wire bundle via hole, is intended to solve this problem of assembling difficulty.
To achieve these goals, the utility model adopts following technical scheme:
A kind of sheath of automotive wire bundle via hole, described sheath comprise centre bore, in-flanges, flanging and be located at described in-flanges and described flanging between groove, described in-flanges all falls within described flanging along in the projection of the axis direction of described sheath along the projection of the axis direction of described sheath.
Preferably, described in-flanges and described flanging profile are provided with arc surface transition.
Preferably, described in-flanges and described flanging and described centre bore junction are provided with arc surface transition.Preferably, described sheath is rubber parts.
The beneficial effect that the utility model produces is:
The utility model is by the optimization to sheath in-flanges structure, size by sheath in-flanges is dwindled, make sheath in-flanges fall within sheath flanging within the projection of same direction along the projection in the direction of sheath axis, ensure when mounted sheath in-flanges one side to be penetrated in vehicle frame hole convenient, solved sheath difficult problem is installed.
Further, in the in-flanges of sheath and the profile of flanging, be provided with arc surface transition, make sheath in-flanges taking arc surface as guiding penetrates vehicle frame hole, be more convenient for the installation of sheath.
Further, the in-flanges of sheath, flanging and the centre bore junction through wire harness are provided with arc surface transition, and the wearing and tearing to sheath while avoiding wire harness to penetrate have extended useful life of sheath.
Further, sheath is rubber parts, utilizes self strain and the each mating surface of vehicle frame plate to fit tightly, and connects simple and reliable.

Embodiment
With reference to Fig. 1, Fig. 1 is the utility model sheath axonometric drawing.Sheath comprise centre bore 2, in-flanges 4, flanging 1 and be located at in-flanges 4 and flanging 1 between groove 3.The concrete structure of sheath can be regarded as by different " recessed " font face edge of both sides height and is rotated counterclockwise after 90 °, extend and form along closed curve, the utility model extends and does not limit along the closed curve of which kind of shape sheath, the shape of closed curve depends on the shape in vehicle frame hole, vehicle frame hole can be designed to circle, ellipse, long waist shaped etc. according to specific needs, in the present embodiment, vehicle frame hole is designed to long waist shaped, and sheath is that concave panel extends and forms along long waist shaped closed curve.
The jacket structure of automotive wire bundle via hole of the present utility model is compared with the improvements of prior art: in-flanges 4 structures to sheath in prior art are optimized, by evenly shrinking to sheath is inner with the onesize in-flanges 4 of flanging 1 physical dimension in existing design, make in-flanges 4 fall within flanging 1 along within the perspective plane of sheath axis direction along the projection of sheath axis direction.Adopt technique scheme, when mounted first in-flanges less jacket structure size 4 is penetrated in vehicle frame hole 5, installation is more prone to, and has reduced the use of sheath material, has avoided waste, has reduced the manufacturing cost of sheath.
Further, be provided with at in-flanges 4 outer mold surface places and be convenient to the arc-shaped transitional surface that sheath is installed, when the in-flanges 4 that sheath is had to an arc-shaped transitional surface penetrates in vehicle frame hole, play the effect of guiding, and in sheath and vehicle frame plate extruding installation process, the arc-shaped transitional surface of in-flanges 4 is understood the automatically inside strain of guide sheath, has more reduced the installation difficulty of sheath.
Continue with reference to Fig. 1, also be provided with arc surface transition at flanging 1 and in-flanges 4 with the junction of centre bore 2, make centre bore 2 flare openings, this technical scheme makes sheath little in the smooth surface contacting with wire harness, frictional force, facilitate wire harness to penetrate, and the wearing and tearing to sheath can reduce or eliminate wire harness penetrating into center hole 2 or wire harness and have displacement with respect to centre bore 2 time, have extended useful life of sheath.
With reference to Fig. 2, Fig. 2 is that the utility model sheath coordinates figure with vehicle frame hole.Vehicle frame plate 5 is provided with vehicle frame hole, and the in-flanges 4 of sheath penetrates behind vehicle frame hole, utilizes each surface of the groove 3 of sheath to fit with the long waist shaped hole face of vehicle frame plate 5 and the surfaces externally and internally of vehicle frame plate 5 respectively.Sheath is elastomer, can select according to application scenario.In the present embodiment, sheath is selected rubber parts, elastic deformation amount is large, strain and the each mating surface extruding of vehicle frame plate by sheath are fixing, save on sheath and vehicle frame plate the structures such as connecting hole have been set, make the installation of sheath more simple and convenient, improved efficiency of assembling, and ensured the reliability connecting.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above embodiment, and be just subject to the restriction of claim, this area common technique personnel can easily modify to it and change, but do not leave essence design of the present utility model and scope.
