At present, transformers are indispensable devices in life and industrial production. The existence of transformers is becoming more and more important. While emphasizing functionality, transformers also need to consider structural rationality. The design and use of transformers are particularly important. It can convert the AC and high-voltage mains electricity commonly used in external circuits into low-voltage DC power for some low-power equipment. The transformer is generally composed of a skeleton, a coil and a magnetic core. The enameled wire is first wound on the skeleton to form a coil. Then the magnetic core is installed on the skeleton body and fixed by colloid.

[0003] The coil in the existing transformer is usually provided with two or more windings, among which the winding connected to the power supply is called the primary coil, and the remaining winding is called the secondary coil. Both the primary coil and the secondary coil of the coil have lead ends; however, the structural design of the existing coil on the transformer is poor, the lead end of the primary coil is exposed outside the magnetic core and fixed by a bracket, and the connection end of the secondary coil is directly connected to other processes after being led out from the magnetic core, so that the user has to limit the connection end of the secondary coil before operating other steps on the transformer, which is troublesome to operate, inconvenient to use, and has a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

Two side columns are provided and are respectively arranged at both ends of the connecting plate. The winding column is arranged between the two side columns, and the winding column of the first magnetic core and the winding column of the second magnetic core are assembled and connected to form a middle column.

[0009] As a preferred solution, one of the winding posts of the first magnetic core and the winding posts of the second magnetic core is provided with a groove, and the other is provided with a protrusion that matches the groove, and the protrusion is adapted to be positioned on the groove to realize the assembly connection of the first magnetic core and the second magnetic core.

[0010] As a preferred solution, epoxy resin glue is provided in the groove, and the protrusion and the groove are bonded by the epoxy resin glue.

[0011] As a preferred solution, a shock-absorbing sleeve is provided on the outer side of the magnetic core, and the second bracket is located on one side of the shock-absorbing sleeve.
