A double-tube iron core transformer for sound box

Abstract

The invention discloses a double-tube iron core transformer for a sound box, the transformer includes a housing and transformer bodies, the plurality of transformer bodies are arranged inside the housing, each transformer body comprises an XLR male head, XLR female head and transform device, the XLR male head and XLR female head are arranged on both sides of the transform device, a fixed plate isarranged at the upper side of the interior of the transformer device, a magnetic core is arranged on an iron core, a first winding group and a second winding group are respectively arranged on both sides of the magnetic core, an input terminal lead is arranged on the first winding group, an output terminal lead is arranged on the second winding group, line holes are arranged at the bottoms of theXLR male head and the XLR female head, which has the beneficial effect that the device of the transformer is arranged inside the housing, and the housing and the transformer device inside are composedof line holes, a line protective sleeve and a water-absorbing sponge, so that the short circuit caused when the transformer device meets water is avoided, and the service life and the safety of the equipment are increased.

Description

technical field [0001] The invention belongs to the field of transformers, in particular to a double-tube iron core transformer for audio. Background technique [0002] Audio isolation transformer is a transformer that works in the audio frequency range, also known as a low-frequency transformer. Due to the hum interference caused by the grounding problem, it can prevent the damage of the input stage of the equipment due to the high potential difference, and realize the safe transmission of the audio signal. [0003] Audio transformers will inevitably encounter excessive humidity during use. If water vapor enters the interior of the transformer, short-circuit faults will easily occur, and faults cannot be found immediately, and the service life is short. Contents of the invention [0004] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical scheme, a double-tube iron core transformer ...
