Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a low-frequency transformer with a plastic-sealed structure. Background Technique

[0002] Low-frequency transformers are used to transmit signal voltage and signal power, can also achieve impedance matching between circuits, and have an isolation effect on direct current. There is no difference in principle between high-frequency transformers and low-frequency transformers, but due to different frequencies of high frequency and low frequency, the iron cores used in transformers are different. Low-frequency transformers generally use silicon steel sheets with high magnetic permeability, while high-frequency transformers use high-frequency ferrite cores.

[0003] However, there are still deficiencies in the prior art. The low-frequency transformers in the prior art do not have a plastic-sealed structure, are prone to electric shock when installed and used, reducing the safety of the transformer; and the encapsulation process is very cumbersome and not easy to repair.

[0004] Therefore, we propose a low-frequency transformer with a plastic-sealed structure to solve this problem. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems put forward in the above background technique, and to propose a low-frequency transformer with a plastic-sealed structure.

[0009] Preferably, the upper end of the first spring is fixedly connected to the inner top surface of the encapsulation shell; the lower surface of the second push plate is set as an inclined surface.
