Description

Technical Field

[0001] The utility model belongs to the manufacture of inductors, and in particular relates to a liquid peeling jig for peeling the ends of three-phase common mode inductor coils. Background Art

[0002] Three-phase common-mode inductors are a special type of inductor, mainly used in three-phase balanced systems to reduce electromagnetic interference and realize complex circuit operations such as frequency response conversion. Three-phase common-mode inductors consist of a magnetic ring and three coils that are insulated from each other and wound around the magnetic ring. Three-phase common-mode inductors are widely used in power electronic equipment and power transmission systems, especially in noise control of DC transmission systems, frequency converters and motor drive systems.

[0003] In the process of manufacturing three-phase common-mode inductors, since the ends of the coils are usually covered with a layer of insulating material, such as insulating paint or insulating film, when connected to an external circuit, in order to ensure the connection and conduction, the ends of the coils need to be peeled to remove the insulating layer and expose the metal wires so as to form a good electrical connection with the external circuit. At present, the peeling of the ends of the three-phase common-mode inductors coils is done by manual hand-held corrosion peeling, which is inefficient and unsafe. The corrosion length of the ends is unstable and it is easy to corrode the coils, resulting in the scrapping of the products. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems of low peeling efficiency, low safety, unstable corrosion length of the end of the existing three-phase common mode inductor coil, and to provide a liquid peeling fixture for the end of the three-phase common mode inductor coil with high peeling efficiency, peeling quality and peeling safety.

[0005] The utility model adopts the technical solution to solve its technical problems: a liquid peeling fixture for the end of a three-phase common-mode inductor coil, including a peeling container, a partition plate is provided on the peeling container, a peeling table is provided on the partition plate, the peeling table is a polygonal hollow structure, a plurality of placement tables are provided above the peeling table, one end of the placement table is fixedly connected to the partition plate, a plurality of peeling insertion holes are provided inside and outside the peeling table, and the peeling insertion holes correspond to the positions of the ends on both sides of the coil.

[0006] Optionally, the peeling table is a hexagonal hollow structure, and three placement tables are provided above the peeling table.

[0007] Optionally, an arc-shaped groove is provided on the peeling table.

[0008] Optionally, the peeling insertion hole is rectangular.

[0009] The usage and principle of the utility model are as follows: the peeling container is filled with peeling liquid, the peeling liquid is heated at high temperature, and the partition is placed in a relatively closed environment by a partition board to improve safety, and then the magnetic ring of the three-phase common mode inductor is placed on the placement table on the partition board, and the coil on the magnetic ring is placed on the peeling table, and the ends on both sides of the coil are respectively inserted into the peeling insertion holes inside and outside the peeling table, and the ends inserted into the peeling insertion holes are in contact with the high-temperature peeling liquid, and the insulating layer on its surface is removed, and the three-phase common mode inductor is removed, and the peeling of the three-phase common mode inductor coil ends is quickly completed. The utility model is not only used for peeling the ends of three-phase common mode inductor coils, but can also be used for peeling the ends of other multi-phase common mode inductor coils.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model has higher peeling efficiency, peeling quality and peeling safety. BRIEF DESCRIPTION OF THE DRAWINGS
