A kind of automobile transformer with negative pressure anti-seepage structure

Abstract

The invention discloses an automobile transformer with a negative pressure anti-seepage structure, which belongs to the field of automobile transformers. An automobile transformer with a negative pressure anti-seepage structure inserts a metal connection plate into the interior of a connection clip spring , to transfer the electrical connection without directly connecting the wire harness inside the shell, which is beneficial to ensure the waterproof sealing at the wiring position. The air pressure is reduced, and the air pressure inside the shell is simultaneously reduced, and the tightness of the insulating cover covering the socket is increased under the action of the pressure difference, thereby effectively improving the overall sealing performance of the device, effectively preventing external rainwater from entering the device, and avoiding the internal leakage of the shell. Damaged by rain erosion.

Description

technical field [0001] The invention relates to the field of automobile transformers, in particular to an automobile transformer with a negative pressure water-proof structure. Background technique [0002] Automobile transformer is a common electrical component in automobile circuit. It converts and adjusts the voltage in the circuit through electromagnetic induction, so that the voltage in the automobile circuit meets its actual working requirements. [0003] The circuit connection of the car transformer is usually directly connected inside the equipment, which results in most car transformers being in an unsealed state. External rainwater can penetrate into the inside of the transformer through the casing. In the prior art, the automotive transformer is usually installed at a higher position inside the car body. [0004] Although the possibility of water ingress into the automotive transformer can be reduced by elevating the installation position of the transformer, in e...

Problems solved by technology

[0004] Although the possibility of water ingress into the automotive transformer can be reduced by elevating the installation position of the transformer, in extreme weather, such as soaking in water, excessive rainfall, washing the vehicle, etc., may cause water to enter the interior of the insufficiently sealed automotive transformer , it is easy to cause damage to the inside of the transformer, and even cause dangerous accidents such as fire in severe cases.
