The invention relates to the technical field of electric power accessories, and discloses a waterproof and dustproof overload protection switch, which includes a device casing, the bottom of the device casing is provided with a wire inlet, and the inside of the device casing is fixedly installed with a positioning The front of the positioning plate is fixed with a fuse box, and the front of the device housing is fixedly fitted with a wire harness outer tube through a positioning sleeve. Both sides of the positioning sleeve are fixedly connected with the front of the device housing. The inner wall of the positioning sleeve is in contact with the outer edge of the outer tube of the wire harness. The waterproof and dustproof overload protection switch rotates the closed screw so that the other end of the closed screw enters the interior of the auxiliary screw, and then completes the closed installation of the device shell and the closed rear panel, and avoids external force and rainwater through the waterproof rubber sleeve Damage to the components inside the device shell, the inner harness does not have direct contact with the outside air and water vapor throughout the whole process, and at the same time, the waterproof layer on the inner wall of the outer tube of the harness is used for waterproof protection to avoid the disadvantages of short circuit caused by water vapor infiltrating into the inner harness , can achieve the effect of high safety and short-circuit prevention of the overload switch.
Description
technical field [0001] The invention relates to the technical field of power accessories, in particular to a waterproof and dustproof overload protection switch. Background technique [0002] The power switch is used to control the switching tube through the circuit for high-speed pass and cut-off. The direct current is converted into high-frequency alternating current and supplied to the transformer for transformation, thereby generating one or more sets of voltages required. [0003] Among them, when the overload switch is in the water vapor or outdoors, when the water vapor is in contact with the wire connector for a long time, the water vapor will easily corrode the parts at the connection between the wire body and the device, resulting in a short circuit of the overload switch, so a new type of wire harness is required. Waterproof and dustproof good overload protection switch. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the d...
