Description

[0002] At present, the waterproof effect of electrical equipment such as lamps and power boxes used in humid or water-containing environments is not good and cannot meet the market demand. The existing electrical equipment uses a waterproof ring to achieve the waterproof function. This structure is not easy to dissipate heat. During the operation of the electrical equipment, a certain amount of heat will be generated. Due to the sealing of the waterproof ring, the internal heat is not easy to dissipate, reducing the service life of the electrical equipment; the waterproof ring is prone to aging and deterioration in some media, losing the waterproof efficiency, allowing water or other media to enter the interior of the electrical equipment, reducing the service life of the electrical equipment and damaging the electrical equipment; moreover, the traditional waterproof method only considers waterproofing on the holes for incoming and outgoing wires, and does not consider the situation where water vapor will enter the interior of the electrical equipment through the gap between the insulating layer of the wire and the metal wire, so the overall waterproof effect is not good.

[0029] The technical solutions of the embodiments of the present application will be briefly described below:
[0030] According to some embodiments, such asFigure 1 , Figure 2 , Figure 4 As shown in ,
[0031] , the present application provides a waterproof inlet structure, and the structure of the waterproof inlet structure is as follows. It includes:
[0031] A waterproof housing 1, with a waterproof groove 2 opened on the inner side of the waterproof housing 1, and an inlet hole 3 opened on one side of the waterproof groove 2;
[0032] A wire, one end of the wire is arranged on the outer side of the waterproof housing 1 for receiving an input electrical signal, and the other end of the wire sequentially passes through the inlet hole 3 and the waterproof groove 2 and is arranged on the inner side of the waterproof housing 1 for electrically connecting the circuit on the inner side of the waterproof housing 1. A part of the insulating layer of the wire in the waterproof groove 2 is peeled off to expose the conductor wrapped in the insulating layer;
[0033] Sealing glue, filling the sealing glue into the inlet hole 3 and between the insulating layer and the conductor in the waterproof groove 2.
[0034] Its function is that the sealing glue is filled into the inlet hole 3 to prevent water vapor from entering the inner side of the waterproof housing 1 from the inlet hole 3; because the other end of the wire sequentially passes through the inlet hole 3 and the waterproof groove 2 and then needs to peel off the outer insulating layer to expose the metal conductor for electrical connection with the circuit board on the inner side of the waterproof housing 1, so water vapor will enter the inner side of the waterproof housing 1 from the gap between the insulating layer of the wire and the metal conductor. To prevent this phenomenon from occurring, the present application fills the sealing glue between the insulating layer and the conductor in the waterproof groove 2, effectively isolating the water vapor outside the waterproof housing 1 and improving the waterproof effect.
