Description

Technical Field

[0001] The utility model relates to the field of mechanized equipment, in particular to a linear mechanism on a transformer coil. Background Art

[0002] Current transformer, abbreviated as CT, converts a large primary current into a smaller secondary current through a certain transformation ratio based on the principle of electromagnetic induction. It is mainly used for line protection, current measurement, electrical isolation, etc. In power supply lines, the current and voltage are relatively high. It is very dangerous to measure directly. Therefore, a transformer is generally used. The transformer can convert high voltage into low voltage, or large current into small current, that is, it plays the role of current conversion and voltage conversion and electrical isolation.

[0003] The transformer generally includes a shell, a transformer coil arranged in a mounting groove of the shell, and a terminal connected to the wire end of the transformer coil. When assembling the transformer, the transformer coil is first installed in the mounting groove of the shell, and then the wire end is welded to the terminal.

[0004] The commonly used transformer housing on the market is shown in the patent document with patent number CN202021730567.1 and name “A transformer housing”, which includes a first shell and a wiring terminal fixed on the first shell by a positioning and mounting structure.

[0005] In order to connect the two ends of the transformer coil with the wiring terminals on the casing, workers are often required to manually wrap the wire ends of the transformer coil around the wiring terminals of the transformer casing. The assembly quality is unstable and the assembly is time-consuming and labor-intensive, which is not conducive to improving production efficiency.

[0006] For the mutual inductor, if mechanization is needed to replace manual assembly, due to the high operating precision of the mechanical equipment, the wires at both ends of the mutual inductor need to be straightened and then input into the corresponding tooling fixture of the equipment before the wire winding and welding work can be carried out.

[0007] In view of this, it is necessary to improve the assembly process of the transformer by automation and mechanization, and provide a linear mechanism for processing the transformer coil. Utility Model Content
