Description

Tinned copper conductor and strippable triple insulated wire

technical field

The utility model relates to an insulated wire, in particular to a tinned copper conductor and peelable three-layer insulated wire.

Background technique

Enameled wire is one of the main types of winding wires. It is usually made by annealing and softening bare copper wires, then painting and baking. Generally, enameled wires include two parts: conductor and insulating layer. When ordinary enameled wire is used to wind the transformer frame, because the withstand voltage of general transformer is 4000V, and the withstand voltage of ordinary enameled wire is 1500V, it cannot meet the withstand voltage requirements of the transformer. Between each layer of enameled wires, an insulating layer is added to make it reach 4000V, which causes waste of insulating materials, increases man-hours and manufacturing processes, and increases the volume of the transformer. Therefore, it is necessary to save insulating materials, reduce man-hours and manufacturing processes, and can not increase the volume of the finished transformer. Insulated wires (130°C) are not applicable. At the same time, in order to meet the convenience of peeling, there are special requirements for the finished product or to prevent solder slag from remaining in the products of the tin furnace, so this new type of tinned copper conductor and peelable type 3 is used. Layer insulated wire.

Utility model content

For enameled wire conductors and direct-soldering triple-layer insulated wires, bare copper wires and direct-soldering triple-layer insulated wires, the use environment is 130°C, but it cannot be used in a higher temperature environment (155°C), and it is easy to peel and has a negative effect on the finished product. In addition to products that require or prevent solder slag from remaining in the tin furnace, the utility model provides a tinned copper conductor and a peelable three-layer insulated wire that can meet this use. The solution of the utility model is: .

Tinned copper conductor and peelable three-layer insulated wire, including tinned copper wire, on the outside of the tinned copper wire, there are PET basic insulation layer, PET and PBT composite voltage insulation layer and PA nylon resistance Grinding the insulating layer; between the tinned copper wire and the PET basic insulating layer, a lubricant is coated.

Preferably, the thickness of the PET basic insulating layer is 0.02-0.03 mm.

Preferably, the thickness of the pressure-resistant insulating layer formed by the composite of PET and PBT is 0.04-0.06 mm.

Preferably, the thickness of the PA nylon wear-resistant insulating layer is 0.02-0.03 mm.

The above-mentioned utility model scheme has the following advantages:

1. It is easy to use, the tinned copper conductor and the peelable three-layer insulated wire are directly wound on the transformer frame, no need to add other insulating materials.

2. Since the insulating material is no longer used, the volume of the finished product after the winding of the transformer skeleton is reduced, thereby reducing the size of the skeleton, magnetic core and other materials, reducing material costs, and reducing the process of adding insulating materials and labor hours. Thereby reducing labor costs.

3. It can be soldered after peeling, without residual substances.

4. The soldering time is short, and the defect rate is greatly reduced.

5. Used in high temperature environment, it is suitable for use in 155°C environment, which greatly improves the safety of the product.

6. Transformers, digital set-top boxes, inductance coils, micro-motors, etc. in consumer electronics products in high-temperature environments (155°C).
