Transformer with hidden wiring terminal and transformer wiring method

Abstract

The invention relates to a transformer with a hidden wiring terminal. The transformer includes a transformer casing and the wiring terminal arranged at an upper end of the transformer casing, whereinan upper surface of the transformer casing is provided with a pit, the pit is detachably covered with a waterproof sunshade cover, a side surface of the transformer casing is provided with a wire insertion hole communicated with the pit, the wiring terminal is arranged in the pit, the wiring terminal includes a copper threaded column, a conductive block fixedly connected with the threaded column,an upper conductive extrusion block which is sleeved on the threaded column and is above the conductive block and a locking nut which is arranged on the upper conductive extrusion block above the conductive block and is in threaded connection with the threaded column to press the upper conductive extrusion block, and an upper surface of the conductive block is lower than a lower side surface of aninner end of the wire insertion hole. The transformer is advantaged in that the aging speed at the wiring terminal can be effectively delayed, a barb can be automatically formed during wiring to prevent a wiring fork from shedding, and a problem of easy aging of a wiring terminal exposed outside in the prior art is solved.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer with hidden wiring terminals and a transformer wiring method. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc. The transformer is equipped with terminals conn...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a hidden terminal transformer which can effectively delay the aging speed at the terminal and can automatically form barbs during wiring to prevent the terminal fork from falling off, which solves the problem that the existing terminal is exposed and easy to age
