While, the protection to internal film layer is improved, safety in utilization greatly improves.Specific technical solution is as follows:
A kind of hermetic type waterproof electromagnetic wire, including copper strap wire, the copper strap wire outside are surrounded with first successively from inside to outside
Film layer, glass layer and the second film layer, the second film layer outer application have a waterproof layer, flat close to copper in first film layer
The side of line has indent, is coated with the first hot melt adhesive layer close to the side of the first film layer on the glass layer, and described the
In two film layers the second hot melt adhesive layer, first hot melt adhesive layer and the second hot melt adhesive layer are coated with close to the side of glass layer
Cross-shaped state, the indent is identical as the extending direction of the first hot melt adhesive layer and position is corresponding.
As an improvement of the above technical solution, indent has multigroup in first film layer, and first film layer is around copper
Rear pressure slot is adjacent on copper strap wire in the shape of a spiral on flat wire.
As an improvement of the above technical solution, the angle between first hot melt adhesive layer and the second hot melt adhesive layer is θ, θ
Geometric ranges be:45 ° of 135 ° of < θ <.
As an improvement of the above technical solution, the angle theta between first hot melt adhesive layer and the second hot melt adhesive layer is
90°。
As an improvement of the above technical solution, first film layer and the second film layer material polyester or polyimides.
There are three advantages for above-mentioned technical proposal tool:
(1) design of indent can guide the cracking direction of the first film layer, so that breach is extended along indent, improve electromagnetic wire
Safety in utilization;
The design of (2) first hot melt adhesive layers and the second hot melt adhesive layer can improve the first film layer, glass layer and second
The reliability connected between film layer improves electromagnetic wire service life;
(3) the first film layer and the second film layer can be isolated in the design of glass layer, avoid the first film layer and
Two film layers crack in same position, while also can preferably be supported to the first film layer and the second film layer, and advantageous effect is aobvious
It writes.

Specific implementation mode
As shown in Figure 1, the present invention provides a kind of hermetic type waterproof electromagnetic wire, including copper strap wire 10,10 outside of copper strap wire
It is surrounded with the first film layer 20, glass layer 30 and the second film layer 40 successively from inside to outside, 40 outer application of the second film layer has anti-
Water layer 50 has an indent 21 in first film layer 20 close to the side of copper strap wire 10, close to the first film layer 20 on glass layer 30
Side be coated with the first hot melt adhesive layer 31, be coated with the second hot melt adhesive close to the side of glass layer 30 in the second film layer 40
Layer 41,41 cross-shaped state of the first hot melt adhesive layer 31 and the second hot melt adhesive layer, the extension side of indent 21 and the first hot melt adhesive layer 31
It is corresponding to identical and position.
In said program, 10 outside of copper strap wire is provided with two layers of film layer:First film layer 20 and the second film layer 40, material can be with
Polyester film or polyimide film are selected, this material is identical as being used in electromagnetic wire film-coating technique in the prior art, can make
There is electromagnetic wire outstanding water resistance to pass through glass layer simultaneously because being additionally provided with glass layer 30 between duplicature
30 pairs of duplicatures are separated, and the mechanical property of glass fibre is more excellent compared with the first film layer 20 and the second film layer 40, Neng Gou
Film layer is protected in electromagnetic wire winding process.Waterproof layer 50 may be used water-repellent paint spraying or dipping mode with around
Electromagnetic wire after packet is compound, and waterproof layer 50 is then made to be fixed to electromagnetic wire surface by way of drying, and when drying beginning,
High temperature can be such that the first hot melt adhesive layer 31 and the second hot melt adhesive layer 41 melts, to improve the first film layer 20 and glass layer 30 it
Between and glass layer 30 and the second film layer 40 between the reliability that connects.
In said program, it is because when electricity to have indent 21, the design close to the side of copper strap wire 10 in the first film layer 20
When magnet-wire bending angle is excessive or winding times are more, due to being close to copper strap wire 10, the first film layer 20 cracks difficulty the first film layer 20
To avoid, then in order to control the first film layer 20 cracking direction, breach can be made to prolong along indent 21 by the design of indent 21
It stretches.Meanwhile indent 21 is identical as the extending direction of the first hot melt adhesive layer 31, and position is corresponding, even if occurring at indent 21
Cracking also can very well carry out the breach at indent 21 protection of long period, be avoided due to the presence of the first hot melt adhesive layer 31
Breach is expanded rapidly, it is ensured that the safety that electromagnetic wire uses.
Further, indent 21 has multigroup, the first film layer 20 rear pressure slot 21 on copper strap wire 10 in the first film layer 20
It is adjacent in the shape of a spiral on copper strap wire 10, the indent 21 of this spiral distribution can guide breach also in the shape of a spiral, so i.e.
Keep the first film layer 20 damaged, also can improve electromagnetic wire on 10 surface of copper strap wire by spiral surrounding under the constraint of glass layer 30
The safety used.
Further, 41 cross-shaped state of the first hot melt adhesive layer 31 and the second hot melt adhesive layer, this setup can
Improve electromagnetic wire it is wrapped during the reliability that bonds between each layer, it is assumed that the first hot melt adhesive layer 31 and the second hot melt adhesive layer 41 it
Between angle be θ, the angle of θ is between 45 ° of 135 ° of < θ <, preferably 90 °.As shown in Fig. 2, the first hot melt adhesive layer 31 is uniformly
Coated on glass layer 30, then glass layer 30 is wrapped in the first film layer 20, makes glass fibrous layer 30 and the first film
It is adhesively fixed by the first hot melt adhesive layer 31 between layer 20;As shown in figure 3, the second hot melt adhesive layer 41 and the first hot melt adhesive layer
31 is similar, is adhesively fixed by the second hot melt adhesive layer 41 between the second film layer 40 and glass layer 30.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention,
The practical range of the present invention is should not be construed as limiting, all changes and improvements made in accordance with the scope of the present invention should all
It still belongs within covering scope of the present invention.
