Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
As shown in Figure 1, present embodiment discloses a kind of vehicle firewall wire harness sheath, including rubber parts 1 and plastic skeleton
2, rubber parts 1 includes the auxiliary set pipe 12 of funnel shaped main casing 11 and funnel type, and main casing 11 is slightly larger than auxiliary set pipe 12, therefore rubber
The top view of part 1 is rendered as an one small big pear shape.The edge of rubber parts 1 is equipped with groove 13, and groove 13 entangles modeling
Expect the edge of skeleton 2.Plastic skeleton 2 is compound rubber part, and shape is also for pyriform, by one side that rubber parts 1 entangles to extension
It stretches, such a structure increases the contacts area of plastic skeleton 2 and rubber parts 1.
As shown in Figure 1, 2, in the present embodiment, 2 outside of plastic skeleton is additionally provided with card-bit part 21, and card-bit part 21 1 is shared
3, one is arranged on larger that of plastic skeleton 2, other two is arranged on the position of 2 concentric reducer transition of plastic skeleton
It puts.Plastic skeleton 2 can be fixed on by card-bit part 21 on vehicle firewall.
In the present embodiment, the material of plastic skeleton 2 use polyhexamethylene adipamide (PA66), the mechanical strength and
Hardness is very high, and rigidity is very big, ensure that the intensity of this wire harness sheath itself.In addition, the material of rubber parts 1 uses ethylene-propylene-diene monomer
Glue (EPDM), the ageing-resistant performances such as resistance to ozone, heat-resisting, weather-proof are excellent, are widely used in automobile component.
In the present embodiment, it is bonded between rubber parts 1 and plastic skeleton 2 using adhesive.Here preferably by easily attached
It and the adhesive of resistance to erosion, the Chemosil 411 of such as German brand vulcanizes adhesive, gluing can be prevented when vulcanizing injecting glue
Agent is washed on mold by EPDM and causes sticking to mould, and common EPDM adhesive trade mark Chemlok 205 easily glues EPDM products
It is connected on mold.
As shown in Fig. 2, in the present embodiment, plastic skeleton 2 can be divided for coated face 22 and masking face 23, coated face 22
The one side that coated with adhesive is bonded with rubber parts 1 is sought to, masking face 23 is exactly to need to cover to prevent from being coated with the one of adhesive
Face.
As shown in figure 3, in the present embodiment, the coated face 22 of plastic skeleton 2 does dermatoglyph processing, ensure that adhesive is more preferable
Ground is attached to the surface of plastic skeleton 2.
As shown in Figure 4,5, in the present embodiment, to play optimal seal effect, plastic skeleton 2 contacts one side with metal plate 3
Curve form match with stamping holes 31, be similarly pear shape.
In the present embodiment, will harness first be passed through into main casing 11, then the screens by 2 stub end of plastic skeleton when mounted
Part 21 is stuck in stamping holes, and then squeezing the position of 2 concentric reducer transition of plastic skeleton makes it completely by stamping holes 31, three cards
Position part 21 clasps metal plate 3 and wire harness sheath is fixed on metal plate 3.It is noted that auxiliary set pipe 12 increases harness for follow-up,
Its sleeve opening is in sealing state when not in use, such as to subsequently increase harness, need to only cut off its sleeve opening, guiding is increased
Harness passes through auxiliary set pipe 12.
As shown in fig. 6, the present embodiment also discloses a kind of coating technique of vehicle firewall wire harness sheath, including following step
Suddenly：
