Description
Technical field
The present invention relates to a kind of water-proof wire bundle.It is more particularly related to a kind of making side of waterproof plastic wire harness
Method.
Background technology
Wire harness have during wiring, often wire harness need to from it is outside can water drenching part situation about entering in annular seal space, by
There is gap between wire harness, water penetration can be made to damage production in annular seal space after spooning water outside the wire harness due to capillary effect
Product.At present, the wire harness of inside stuffing is coated with using outer wrap thing parcel mostly, prevents inside from filling out by outer wrap thing
Fill beyond the region of objective existence to let out, and the effect of locking positioning is got to wire harness.But these methods are difficult to filling out completely for gap between line line
Fill, and the easy aging of outer wrap thing is damaged and inside stuffing is leaked, and causes internal wire harness to be filled up completely with, and lose
Water-proof function is lost, the service life of wire harness is reduced.Different measures has been employed in the past to solve this problem, for example specially
With the normal temperature such as interior filling PUR, thermoplasticity or thermosetting resin be the packing material of solid-state in the sharp A of CN 105097100 come
Prevent inside stuffing from leaking.But one be in the method to be put into mould after the filler of melting is coated on into wire harness surface
In, another is the filler of filling melting after wire harness is directly placed into mould, and the filler of melting easily solidifies and line to the cold
Between beam there is the filler that inhomogenous problem can cause some places to be difficult filling melting in gap, and some contacts are close
Filler that is local then being difficult to make melting is passed through and filled, and still results in the presence in gap, and wire harness in a mold can not
Position well and in center, the interior filling water-proof wire bundle side after cooling can be caused to have thicker PUR another
Side then has relatively thin PUR.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantage that at least will be described later.
It is a still further object of the present invention to provide a kind of preparation method of waterproof plastic wire harness, it is woven using cotton thread and solved
The problem of filler permeates insufficient between wire harness, is divided into interior wire harness and external beam by a branch of wire and handles respectively, effectively
Wire harness service life is extended, and whole manufacturing process production efficiency is high, and Master Cost is low, and production cost is low.
In order to realize that there is provided a kind of making side of waterproof plastic wire harness according to object of the present invention and further advantage
Method, comprises the following steps：

Step 3: the waterproof portion of the external beam is woven with cotton thread so that the external beam is connected to each other in roller shutter shape
Together, the waterproof portion of the external beam is applied with hot-fusible pressure-sensitive adhesive, by the external beam of coated hot-fusible pressure-sensitive adhesive wound on institute
Mould is put into after the excircle for stating closed-cell foam layer；
Step 4: after the outer filler after injection heating melts into the mould, matched moulds cooling and solidifying, mould is opened,
Wire harness is taken out, the waterproof plastic wire harness is produced.
Preferably, inner stuffing described in step 2 is that mass ratio is 2-4:1 vaseline and the mixture of silicone.
Preferably, inner stuffing described in step 2 is that mass ratio is 1-3:1 lanolin and the mixture of silicone.
Preferably, the cotton thread is placed in liquid paraffin by cotton thread described in step one and step 3 before braiding
Drained after immersion.
Preferably, 1/10th of a diameter of every diameter of wire of the cotton thread.
Preferably, the outer filler is polyamide hot or thermosetting epoxy resin.
Preferably, the external beam in step 3 on the excircle of the closed-cell foam layer is put into mould
Before tool, mould inner surface lays plastic sheeting.
The present invention at least includes following beneficial effect：
Firstth, wire harness waterproof portion is compiled with cotton thread in described in the preparation method of waterproof plastic wire harness of the present invention
Knit so that the interior wire harness is connected to each other in roller shutter shape, woven using cotton thread, interior wire harness is arranged successively and promote
There is certain gap in interior wire harness between each wire, promote infiltration of the inner stuffing in interior wire harness between each wire,
The problem of avoiding filling insufficient caused by the heterogeneity of gap between each wire in interior wire harness, and cotton thread can be well
It is impregnated with and is blended by inner stuffing, further, because the capillarity of cotton thread can further promotes inner stuffing in interior lines
