This water resistance to vehicle brings acid test.And neutral net of the vehicle harness as vehicle, carry this electric current and
The transformation task of signal, so harness waterproof, once failing, the lighter causes electrical function to fail, serious short circuit to be caused to cause
The disasters such as vehicle fire.So the water resistance design of vehicle harness seems particularly heavy in the design of whole vehicle electric system
Will.
Realize comprehensive waterproof of harness, the waterproof of vehicle harness not only needs to consider the outer waterproof of harness, but also also needs to
Consider harness inner waterproofing.The outer waterproof of harness belongs to the horizontal waterproof of harness, the purpose is to prevent steam by harness profile direction into
Enter to inside harness.Due to being coated with insulated enclosure layer outside the conducting wire inside harness or signal wire itself, for
The waterproof performance requirement relative loose of the outer waterproof of harness.There are the technological means of the outer waterproof of a large amount of harness in the prior art.
Harness inner waterproofing belongs to longitudinal waterproof of harness, the purpose is to prevent steam by the gap between conducting wire and conducting wire, and along
Harness extending direction is penetrated into the other end of harness by one end of harness.Enter as harness inner waterproofing can be used in harness in vehicle
The opening of the confined space (controlling part in such as electric appliance) of some stringent waterproof of needs of portion, to prevent external moisture by harness
Gap is entered in the confined space, and causes exposed terminal or other electrical connectors existing in the confined space
There is oxidation and rusting, and cause the loose contact even situation of short circuit.Therefore it is high for the waterproof performance requirement of harness.So
And deficiency is paid close attention in vehicle manufacture field for harness inner waterproofing at present, in the prior art almost without on harness inner waterproofing
Technological means occurs.
Utility model content
To be solved in the utility model is the problem of existing vehicle manufacture field considers deficiency for harness inner waterproofing, is carried
For a kind of automobile-used water-proof wire bundle, it can realize the inner waterproofing of harness.
To solve the above problems, the utility model is achieved through the following technical solutions：
A kind of automobile-used water-proof wire bundle, including harness body and water-proof plug glue.The harness body is by the conducting wire group of more than 2
Into.The water-proof plug glue is filled in the gap location between the conducting wire and conducting wire of harness body.
In such scheme, water-proof plug glue is also further coated on the outside of harness body.
In such scheme, the outside of water-proof plug glue also further coats rubber sleeve.
In such scheme, water-proof plug glue is implastic resin or hot melt adhesive in harness body use temperature range.
In such scheme, the fusing point of water-proof plug glue is 80 DEG C~130 DEG C.
Compared with prior art, the utility model has following features：
1st, the water-proof plug glue being filled between the conducting wire and conducting wire of harness body, can effectively improve the inner waterproofing of harness
Can, to prevent gap location of the water vapour between conducting wire and conducting wire, harness is penetrated into by one end of harness along harness extending direction
The other end of body；
2nd, the water-proof plug glue of harness outer body is wrapped in, the outer water resistance of harness can be effectively improved, to prevent water
Vapour is entered inside harness by harness profile direction；
3rd, water-proof plug glue is liquid on harness body use temperature range so that water-proof plug glue can preferably penetrate into
Into the gap between the conducting wire and conducting wire of harness body；
4th, water-proof plug glue is solid-state within harness body use temperature range, can guarantee that high temperature during vehicle operation and shakes
Effective water resistance of harness still can be effectively ensured under rotating ring border.

Embodiment
A kind of automobile-used water-proof wire bundle, as shown in Figure 1, being mainly made of harness body 1 and water-proof plug glue 2.Wherein harness sheet
Body 1 is used harness on existing vehicle, which includes the conducting wire of more than 2, and the wherein conducting wire is electric wire
And/or signal wire.In order to realize harness inner waterproofing, water-proof plug glue 2 is filled between the conducting wire and conducting wire of harness body 1
Gap location.All conducting wires of whole harness are closely sticked together by water-proof plug glue 2 herein, with prevent water vapour from conducting wire with
Gap location between conducting wire, the other end of harness body 1 is penetrated into along harness extending direction by one end of harness body 1.For
The water proofing property of harness is further improved, can realize the outer waterproof of harness, water-proof plug glue 2 is also further coated on harness sheet
The outside of body 1.Water-proof plug glue 2 herein is fully wrapped around by the outer radial of harness body 1, to prevent water vapour by harness section side
To entering inside harness.
The length of water-proof plug glue 2 is much smaller than the length of harness body 1, i.e. water-proof plug glue 2 is provided only on harness body 1 and extends
On wherein one section of direction.In the utility model, water-proof plug glue 2 is arranged on harness, and into vehicle interior, some needs strictly to prevent
On one section of the opening of the confined space (such as intersection inside and outside vehicle) of water.Harness work can be influenced since water-proof plug glue 2 is too long
Dynamic flexibility, water-proof plug glue 2 is too short and does not have the effect of waterproof, therefore in actual design, the length one of water-proof plug glue 2
As be slightly longer than harness external seal connector length.
The section shape of water-proof plug glue 2 is engaged with the opening shape of be applicable in confined space.Such as opening for confined space
When mouth is circular hole, the section shape of water-proof plug glue 2 is circle, referring to Fig. 2.When opening such as confined space is square hole, water-proof plug
The section shape of glue 2 is square, referring to Fig. 3.
Water-proof plug glue 2 is is implastic resin or hot melt adhesive in 1 use temperature range of harness body.Water-proof plug glue 2 exists
It is liquid on 1 use temperature range of harness body so that in the process of harness, water-proof plug glue 2 can preferably ooze
Enter into the gap between the conducting wire and conducting wire of harness body 1, water-proof plug glue 2 can be preferably in contact with conducting wire.And prevent
Water blocking glue 2 is solid-state within 1 use temperature range of harness body so that in the course of work of harness, water-proof plug glue 2 can
The form of solid is kept, high temperature during effective water resistance of harness, particularly vehicle operation so can be effectively ensured and shake
Effective water resistance of harness still can be effectively ensured under rotating ring border.In the utility model, the fusing point of water-proof plug glue 2 for 80 DEG C~
130℃。
In order to preferably keep the fitness of the opening of harness and confined space, and also to avoid residing for harness
The situation that water-proof plug glue 2 caused by the abnormal high temperature of working environment deforms, the outside of the harness body 1 and water-proof plug glue 2
Also further coat rubber sleeve 3.
The production process of the utility model is as follows：Harness body 1 is horizontal positioned in a mold, and by after heating and melting
Water-proof plug glue 2 is instilled in mould so that the surface of conducting wire of the water-proof plug glue 2 coated on harness body 1.By mold clamping, pass through
The extruding of mould enables the gap location that water-proof plug glue 2 is preferably penetrated between conducting wire and conducting wire.After cooling and solidifying, open
Mould, takes out the harness with water-proof plug glue 2, you can obtains the utility model.
