Problems solved by technology

The existing transformer terminals lead out the power supply by connecting the electric ring with a metal structure to the power line, which not only has the disadvantage that the electric ring is not easy to compact, but also sparks will increase the contact resistance and increase the electric energy in the power transmission and transformation loss
Wire terminals are widely used in the world's electrical and electronic engineering industries: large transformers, etc.; Chinese utility model patent CN208093334 U discloses a transformer terminal. The terminal of this structure includes a line card and a base, and one end of the base is connected to the transformer. , the other end of the base is connected to the line card. This kind of terminal has the characteristics of easy locking and disassembly. In the normal temperature range, the terminal will not cause high temperature failure, but the connecting part of the line card and copper conduction, contact The resistance is higher than that of the normal copper wire, and the current passing through during the electrification process will cause the risk of heating. In addition, the terminal is generally not well ventilated, which will further cause heat accumulation, resulting in certain power loss and safety hazards, limiting its use. scope of application

Description

technical field [0001] The invention relates to a connection terminal, in particular to a transformer connection terminal. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The substrate structure of the transformer includes a transformer casing and a coil and an iron core arranged in the transformer casing, and the coil includes a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. The existing transformer terminals lead out the power supply by connecting the electric ring with a metal structure to the power line, which not only has the disadvantage that the electric ring is not easy to compact, but also sparks will increase the contact resistance and increase the electric energy in the power transmission and transformation ...
