Description

Technical field:

[0002] A magnetizing coil is a device for generating a magnetic field. It is composed of a number of coils wound around an iron core. When current passes through the coil, a magnetic field is generated. In the design of the magnetizing coil, the coil is usually wound around a copper tube with an insulating layer, and a large-diameter single-core cable is used to connect the copper tube as the power circuit of the magnetizing coil. At present, the single-core cable and the copper tube with an insulating layer are connected using soft copper wire. Due to the large difference in size between the copper tube and the single-core cable, it is difficult to wrap and bundle them with soft copper wire, and it is very easy to loosen, resulting in short-circuit damage to the magnetizing coil. Utility model content:

[0003] The utility model aims to provide a connection structure of a magnetizing coil.

[0004] The purpose of the utility model is implemented by the following technical scheme: a connection structure of a magnetizing coil, which includes a copper plate, a copper nose and a U-shaped pipe clamp; the copper nose is provided at one end of the copper plate, and the copper plate is connected to the nose end of the copper nose by bolts; the U-shaped pipe clamp is provided at the other end of the copper plate, and the two ends of the U-shaped pipe clamp are fitted with the plate surface of the copper plate and connected by bolts; one end of the copper tube is wound into a magnetizing coil, and the other end of the copper tube transversely passes through the space formed by the U-shaped pipe clamp and the plate surface of the copper plate, and the end of the copper tube is provided with a flared joint, and the flared joint is threadedly connected to the end of the cooling water pipe.

[0005] Preferably, the inner surface of the U-shaped tube clamp fits tightly with the outer surface of the copper tube.

[0006] Advantages of the utility model: First, the utility model uses copper plates, copper noses, and U-shaped pipe clamps to make a connection device, which connects the power transmission wire to the copper pipe wound with the magnetizing coil, replacing the soft copper wire winding and bundling, which is simple to operate and not easy to loosen, thus avoiding short circuit damage to the magnetizing coil. Secondly, the copper pipe is connected to the cooling water pipe through a flared joint, and cooling water is introduced to cool down in time, reduce the heating of components, and avoid damage to the magnetizing coil; in addition, the copper plate, copper nose, U-shaped pipe clamp, and flared joint are all made of copper materials, which have the advantages of low resistance and high conductivity, and can further reduce the heating of components and enhance the magnetic field of the magnetizing coil.

[0007] Second, the utility model fixes the copper tube on the copper plate through the U-shaped tube clamp, which is easy to disassemble and install, and the operation is simple. The U-shaped tube clamp can be installed on the upper surface or the lower surface of the copper plate according to the usage. In addition, the installation direction of the copper tube can be selected according to the winding condition of the magnetizing coil, so as to adjust the direction of the flared joint, which is convenient for connecting the flared joint with the cooling water pipe.
