A product protection structure for enhancing waterproofing performance

Abstract

The invention provides a product protection structure for enhancing waterproofing performance, comprises a product outer shell, wherein the product outer shell is a hollow structure with an upper endopening, a mounting plate is fixedly connected with a rear side of the product outer shell, a crimping plate is installed on the mounting plate, a connection joint part is arranged between the productouter shell, the crimping plate and the mounting plate, and a lead cable is inserted into the connection joint part. As that lead cable is insert into the wiring joint, a polyurethane elastomer potting adhesive can be used as the potting adhesive layer, It is non-foamed adhesive, its adhesion and waterproofness are better than foamed sealant, even if the surface layer is damaged, rainwater and moisture can not enter the inner layer, thus effectively preventing the rainwater and moisture from entering the outer shell of the product, effectively ensuring the normal work of the electrical components inside the outer shell of the product.

Description

technical field [0001] The invention belongs to the technical field of electrical waterproofing, in particular to a product protection structure with enhanced waterproof performance. Background technique [0002] Waterproofing is no longer a fresh topic. Whether it is tunnels, bridges, dams, roads, buildings or the houses we live in, waterproofing cannot be ignored. At the same time, the electrical products we use in our daily life also have waterproof and moisture-proof problems that must be faced directly. [0003] When the product is used in electrical equipment, the waterproof performance of the product is extremely important. If there is a problem of water leakage or water ingress in the product, if the liquid comes into contact with the electrical equipment in the product, it is very easy to damage the circuit board or electrical components in it. Moreover, in an open-air environment, due to the influence of the weather, it is even more necessary to ensure the waterpr...

AI Technical Summary

Problems solved by technology

Due to the application characteristics of the product, it needs to be installed on the side of the track all the year round, and the internal electrical components of the product are easily affected by the humid environment, causing electrical parameters to drift, resulting in a decline in the performance of the whole machine

At present, the common method is to add a protective plate on the upper part of the potting body, so that the potting body of the equipment does not directly contact the sleeper board. It is easy to generate relative friction between the plates, which will damage the crust and cause the negative impact of water vapor ingress

Currently there are problems: 1. The existing products are potted with polyurethane foam glue. Due to the sponge structure inside after the foam glue is cured, the thickness of the waterproof crust on the surface is less than 5mm, and the equipment is installed outdoors all the year round. When the crust is damaged, the rainwater will penetrate into the potting body from the damaged point through respiration, and directly affect the electrical components

2. The shape of the joint between the lead wire and the potting body is irregular, and it is difficult to form a skin on the foam glue, and when the cable moves, it will cause deformation of the joint, resulting in a water vapor intrusion channel

3. The thickness of the outer protective layer of the leading cable is low, which cannot meet the needs of long-term open-air work in the field
