Abstract
Description
Technical Field
[0001] The utility model relates to the field of micro transformer processing, in particular to a clamp for producing a micro transformer. Background Art
[0002] The working principle of the micro transformer is based on the principle of electromagnetic induction.
[0003] When AC current passes through the primary winding of the transformer, an alternating magnetic field is generated around the winding. This alternating magnetic field passes through the iron core, and due to the magnetic conductivity of the iron core, most of the magnetic lines of force form a closed loop along the iron core.
[0004] At the same time, this alternating magnetic field will pass through the secondary winding, and according to the law of electromagnetic induction, an electromotive force will be induced in the secondary winding. If the secondary winding forms a closed loop, current will flow through it.
[0005] The number of turns of the primary winding and the secondary winding is different, so as to achieve voltage conversion. If the number of turns of the secondary winding is more than that of the primary winding, the output voltage will increase, thus achieving voltage boost; conversely, if the number of turns of the secondary winding is less than that of the primary winding, the output voltage will decrease, thus achieving voltage reduction.
[0006] The general process of micro-transformer production is: winding, assembling core, welding lead wires, insulation treatment, testing, varnishing and inspection packaging; during the processing of micro-transformers, the neatly arranged transformer blanks need to be clamped on the workbench and operated manually. It is impossible to clamp multiple transformers at a time, and the work efficiency is low. Utility Model Content

[0009] Preferably, the handle is a rectangular structure made of plastic material, and the bottom of the handle is fixed by two sets of guide columns and a clamping plate, and the handle and the clamping plate are arranged in parallel.
