Description
Technical field
The present invention relates to a kind of automotive wire bundle field, be specifically related to a kind of automobile wiring harness sheath.
Background technology
Because automotive engine harness is positioned at driver's cabin outdoor; instrument desk wire harness is positioned at driver's cabin indoor; communication is there is between engine wire harness with instrument desk wire harness; so when engine wiring harness enters in driver's cabin through cab floor panel beating, rubber sheath is usually used to cut from panel beating for the protection of wire harness herein.
As shown in Figure 1 and Figure 2; existing wire harness is through body platform stamping holes; because body platform panel beating 7 is steel plate; it is insulated hull outside wire harness; wire harness insulated hull is easily cut by floor panel beating; and play the effect of protection wire harness by the rubber sheath 6 be embedded on panel beating, prevent body platform panel beating 7 from being cut by overall wire sheaves, and then cause wire harness safety problem.The rubber sheath 6 that existing automotive wire bundle uses, on rubber sheath 6, generally design the rectangle groove 61 that panel beating can be made to embed, the mode coordinated with rectangle groove 61 by body platform panel beating 7 realizes fixing.But there is its own shortcomings in this rubber sheath 6:
1. rubber sheath is without fixed hole position, and only adopt the fixed form that extruding compresses, extruding force is little, and rubber sheath is fixing not firm, after using for a long time, easily comes off.And the vibration existed in vehicle travel process, rubber sheath can be caused to there is nondirectional left and right micro-displacement, rubber sheath is subject to the active force (emphasis is the power of left and right directions moment change) from body platform panel beating, long-term friction between such rubber sheath and panel beating, causes rubber sheath to decline useful life.
2. the thrust of rubber sheath and panel beating vertical direction is very little, and automobile storage is in vibration, and easily intake by rectangular recess, sealing effectiveness is poor.
3. rubber sheath is overall is elastomeric material entirely, and do not have other reinforced members, intensity is poor.
Summary of the invention
In order to solve the problem, the invention provides a kind of fixing reliable, good sealing effect, intensity is high, vibration deformation quantity is little, the automobile wiring harness rubber sheath that the life-span is long.
Technical scheme for the employing that achieves the above object:
A kind of automobile wiring harness sheath, it comprises rubber sleeve and two semiorbicular fixed covers, described rubber sleeve comprises body, stretch into portion and flange, describedly stretch into portion, described flange and described body are connected as a single entity, the described portion of stretching into is cylindric, the described external diameter stretching into portion is greater than the external diameter of described body, the fixing hole of the described outer circumferential walls and Metal Sheets for Body-manufacturing that stretch into portion coordinates, fit in the lower surface of described flange and the surface of described Metal Sheets for Body-manufacturing, two described fixed covers block the groove of described rubber sleeve and fit with the upper surface of described flange and side, described fixed cover, described flange and described Metal Sheets for Body-manufacturing are bolted.
Selectable, the inward flange of described fixed cover has flange upwards, and described flange and described groove fit realize clamping.
Selectable, two described fixed covers are fixedly connected with.
Selectable, described in be fixedly connected with and realized by following manner: one end of two described fixed covers has barb, and the other end has the square hole coordinated with described barb.
Selectable, two described fixed covers have one end tilting of square hole.
Selectable, described flange is Flange-shaped Parts.
Selectable, described flange has the cascaded surface in vertical axial direction, and upper end is boss-shaped, and this boss-shaped structure coordinates with described fixed cover.
Selectable, described fixed cover, described flange have for bolted installing hole, and the number of described installing hole is 2, and one of them is mounting hole.
Selectable, described in stretch into portion lower surface there is multiple blind hole.
Selectable, described blind hole is trapezoidal hole, and the center stretching into portion relatively distributes axisymmetricly.
Selectable, the body of described rubber sleeve has helical structure or ripple struction.
Selectable, the surface of described fixed cover has antirust coat.
Beneficial effect of the present invention:
Only rubbery material parts is had relative to existing rubber sheath, wire harness sheath of the present invention adds fixed cover structure, automobile wiring harness sheath comprises rubber sleeve and two fixed covers, rubber sleeve has the groove coordinated with fixed cover inward flange, two fixed covers block groove and are covered, groove has good positioning function, makes fixed cover not easily play occur, and fixed cover, rubber sleeve and Metal Sheets for Body-manufacturing are bolted and realize fixing.With boltsly achieve the reliable fixing of wire harness sheath, this fixed cover structure plays the effect of reinforcement, skeleton to rubber, enhance the structural strength of wire harness sheath entirety and fixing reliability; And rubber sleeve coordinates with fixed cover and defines a stressed entirety, have wear-resisting, damping, shock proof feature, after bolt tightening, the flange lower surface of rubber sleeve and the intimate surface of Metal Sheets for Body-manufacturing are fitted, and have good sealing.
Further, the inward flange of fixed cover has flange, and flange increases the local contact area of inward flange and body, namely increases lifting surface area, places and snap-fit engagement is herein stablized, reduce stress and concentrate, both reduced the damage to body simultaneously.
Further, two fixed covers connect as a whole, define the skeleton of stability, enhance overall construction intensity.The two ends of fixed cover have barb and square hole respectively, and the barb of a fixed cover coordinates with the square hole of another fixed cover the connection achieving two fixed covers, just can realize fixing by mechanical connection, and structure is simple, reliable.
Further, one end that fixed cover has square hole tilts, and is convenient to the installation of two fixed cover barbs and square hole, tilts and makes mating surface be curved surface, when there is vibration, still can ensure to coordinate closely.
Further, flange is Flange-shaped Parts, increases the contact area on flange and Metal Sheets for Body-manufacturing surface, and the installing hole place of wire harness sheath is not easily torn.
Further, the upper end of flange is boss-shaped, the side of flange is only partly covered, ensure that with vehicle body contact site be rubber entity part, if the side of flange is completely encased, under the urgent state of assembling, the lower limb of whole fixed cover can contact Metal Sheets for Body-manufacturing, makes overall sealing property not good.
Further, one of them installing hole is mounting hole, ensure that when Metal Sheets for Body-manufacturing produces certain mismachining tolerance, still can realize assembling, have good adjustability.
Further, the lower surface stretching into portion has multiple blind hole, ensure that wire harness can more easily pass body, and wire harness is worn in sheath process, coordinates staving press, this structural design, through the wire harness than Circularhole diameter more overstriking, can be more prone to threading.And hollow out process can material saving, reduce costs, be beneficial to car load simultaneously and fall heavily.
Further, the trapezoidal hole that blind hole distributes axisymmetricly for the center stretching into portion described in relatively, takes this structure to make the die sinking stress distribution in the portion that stretches into even.
Further, body is helical structure or ripple struction, has good scalability, and when the wire harness of body pulls, rubber sheath helical structure or ripple struction can stretch, and what wire harness can realize certain limit pulls adjustment.
Further, the antirust coat on fixed cover surface has antirust, etch-proof function, enhances the useful life of part.
