Electromagnet power source structure

Abstract

The invention discloses an electromagnet power source structure which comprises a coil assembly, an outer shell, a fixing plate, a connecting piece, three pins and a connector. The outer shell is of a U-type structure, and the coil assembly is fixed in the outer shell. The fixing plate is placed on the middle outer side face of the outer shell and connected with the outer shell in a fastening mode. The connecting piece is of a three-section structure, and the ends of the connecting piece are connected with coils in the coil assembly respectively. One end of each pin is fixed to the connecting piece. The connector is of a cylindrical structure and provided with a bottom surface, an open structure is formed in the other end of the connector, three through holes are correspondingly formed in the bottom surface of the connector and used for placing the pins, the bottom surface of the connector is fixedly connected with the connecting piece and the fixing plate, and the three pins are correspondingly inserted into the three through holes. The electromagnet power source structure is simplified, redundant molds and procedures can be reduced, and therefore cost is saved. Electric resistance welding is adopted for connection, investment of labor cost is reduced, and machining and assembling can be achieved through a semi-automatic production line. The product performance is stable, the structure is reliable, and the yield of products is improved.

Description

technical field [0001] The invention relates to a power supply structure, in particular to an electromagnet power supply structure. Background technique [0002] The electromagnet is made by using the principle of the magnetic effect of the current, and has many advantages. For example, whether the magnetism of the electromagnet can be controlled by the current on or off, and the magnitude of the magnetism can be controlled by the strength of the current or the number of turns of the coil. It is also possible to change the size of the resistance current to control the size of the magnetism, and its magnetic pole can be controlled by changing the direction of the current, and so on. That is, the strength of magnetism can be changed, the presence or absence of magnetism can be changed, the direction of magnetic poles can be changed, and magnetism can disappear due to the disappearance of current. Using the above advantages of electromagnets, people have widely applied them to...

Problems solved by technology

However, the current electromagnet power supply structure is relatively complicated, and there are many processing procedures. At the same time, the parts are mainly connected by soldering, so there are still the following defects: many processes, many molds, and high cost; the welding reliability of soldering is low. The high temperature resistance level of the welding area is different, and there is a risk of falling when the electromagnet is in overload operation, resulting in low product yield and time-consuming and laborious
