Abstract

The utility model discloses a double glass fiber layer lapped rectangular copper wire, which is formed by lapping double glass fiber layers onto a rectangular copper wire and coating bonding enamel layers among the layers and on the surface of the rectangular copper wire. The double glass fiber layers are meshed glass fiber layers having the lapping lay larger than 5.5mm and smaller than 7.5mm and the lapping angle larger than 10 degrees and smaller than 30 degrees. The performance indexes of the rectangular copper wire, such as curvature, attachment and the like, are improved, use requirements can be met, and service life of the rectangular copper wire is prolonged.

Description

Double glass fiber copper-clad lenticular wire

Technical field

The utility model relates to a kind of double glass fiber copper-clad lenticular wire, particularly relates to a kind of double glass fiber copper-clad lenticular wire that is suitable for dried motor, electric equipment products.

Background technology

At present, motor, the used winding wire of electric equipment products generally adopt wrapped double glazing silk on copper strap wire or the mica tape copper-clad bolt for fastening a door from outside line, and scribble one deck bonding lacquer with the surface between each layer, to solve insulation.

It is 1-2 ° of wrapping angle that but the double glazing silk of these structures all adopts fine pith, when coiling, the bending and the adhesion property of winding wire do not reach requirement, in use easily produce the insulating barrier cracking on the flexure plane of winding coil, and its coil is destroyed and reduction of service life.

The utility model content

The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of cancellated double glass fiber copper-clad of coarse pitch lenticular wire that has, with performance index such as improve bending, adhere to, can satisfy instructions for use, increase the service life.

The purpose of this utility model realizes in the following way.The utility model is to work energetically 10 ° netted glass fiber layers less than 30 ° wrapping angles less than 7.5 millimeters lay of lapping in employing on the prior art basis more than 5.5 millimeters.

Further, the double glazing silk adopts the netted glass fiber layer of 25 ° of wrapping angles of 6 millimeters lay of lapping.

The utility model is because of having adopted wrapped coarse pitch, and winding wire bending crack phenomenon when having avoided coiling can guarantee that insulating barrier is close on the copper strap wire, therefore increases the service life, and improves performance index such as bending, tack

Description of drawings

Just the utility model is described in further detail with enforcement below in conjunction with accompanying drawing:

Fig. 1 is a wrapping angle schematic diagram in the prior art;

Fig. 2 is the utility model lay of lapping or wrapping angle schematic diagram;

Fig. 3 is the technological process of production schematic diagram of the utility model double glass fiber copper-clad lenticular wire.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

As shown in Figure 1, adopted 1～2 ° of wrapping angle in the prior art, when coiling, particularly the glass fiber of crooked position reduces adhesion property because of bending crack like this.As shown in Figure 2, it is less than 7.5 millimeters more than 5.5 millimeters that the utility model has adopted lay of lapping n, wrapping angle a works energetically 10 ° less than 30 ° netted glass fiber layer, therefore winding wire bending crack phenomenon in the time of avoiding coiling, and guaranteed that glass wire is close on the copper strap wire, particularly can improve copper strap wire crooked position adhesive force.Preferably, the double glazing silk adopts the netted glass fiber layer of 25 ° of wrapping angles of 6 millimeters lay of lapping.

As shown in Figure 3, the production technology of the utility model double glass fiber copper-clad lenticular wire, may further comprise the steps: outside copper strap wire (or mica tape copper-clad lenticular wire), be coated with the bonding lacquer, cure wrapped alkali-free glass wool, soak the bonding lacquer, cure,, soaking the bonding lacquer to the wrapped glass fiber of opposite direction, cure, being coated with bonding lacquer again and curing and form.

The above is all so that the utility model conveniently to be described, in the spiritual category that does not break away from the utility model creation, the various simple covert and modification that those skilled in the art did of being familiar with this technology still belongs to protection range of the present utility model.

Claims

1. double glass fiber copper-clad lenticular wire, by wrapped double glazing silk on the copper strap wire, between each layer and surface scribbles one deck bonding lacquer and forms, and it is characterized in that: the double glazing silk adopts and works energetically 10 ° of netted glass fiber layers less than 30 ° of wrapping angles less than 7.5 millimeters lay of lapping more than 5.5 millimeters.

2. a kind of double glass fiber copper-clad lenticular wire according to claim 1 is characterized in that: the double glazing silk adopts the netted glass fiber layer of 25 ° of wrapping angles of 6 millimeters lay of lapping.
