Automobile transformer with negative-pressure water seepage prevention structure

Abstract

The invention discloses an automobile transformer with a negative-pressure water seepage prevention structure, which belongs to the field of automobile transformers. According to the automobile transformer with the negative-pressure water seepage prevention structure, a metal power connection plate is inserted into a power connection clamp spring, electric connection is switched, a wire harness does not need to be directly connected into a shell, the waterproof sealing performance at the wire connection place is ensured; meanwhile, the negative pressure forming tank is communicated with the shell, the air pressure in the shell is synchronously reduced by means of reducing the air pressure in the negative pressure forming tank, and the tightness of the insulating cover plate covering the plugging port is improved under the action of pressure difference, so that the overall sealing performance of the device is effectively improved, external rainwater is effectively prevented from entering the device, and the interior of the shell is prevented from being eroded and damaged by the rainwater.

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.
