Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of terminal boxes, and particularly relates to an inverter stainless steel terminal box with built-in shutters. Background Art
[0002] An inverter is a converter that converts DC electrical energy (batteries, accumulators) into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated alternating current (generally 220V, 50Hz sine wave). It consists of an inverter bridge, control logic, and a filter circuit. It is widely applicable to air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
[0003] At the present stage, most inverter terminal boxes are temporarily made on-site. The materials and processes may vary depending on the on-site conditions, the quality and performance may be unstable, and there may be a lack of necessary protective measures, such as anti-corrosion and rust prevention. During the manufacturing process of the product, human operation errors may lead to quality defects in the product manufacturing process, which not only increases costs but also affects customer satisfaction. Summary of the Utility Model
[0004] The purpose of the present utility model is to provide an inverter stainless steel terminal box with built-in shutters to solve the technical defects pointed out in the background art.
[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows:
[0006] An inverter stainless steel terminal box with built-in shutters, including a stainless steel box body. The interior of the stainless steel box body is divided into a DC area and an AC area by a partition. Inverters are correspondingly installed in the DC area and the AC area. Shutters for heat dissipation and ventilation are symmetrically arranged on both sides of the stainless steel box body.
[0007] Further, a number of rubber membranes are evenly spaced at the bottom of the stainless steel box body. AC and DC cables need to pass through the rubber membranes when entering the box body, and the rubber membranes form a waterproof function for the cables to extend into.
[0008] Further, the front side plate of the stainless steel box body is provided with a pair of door panels. The side parts of the door panels are hinged to the stainless steel box body through hinge seats, and the two door panels are locked through a door lock.
[0009] Further, the corners of the stainless steel box body are polished smoothly, and rubber is pasted at sharp points.
[0010] Further, the surface of the stainless steel box body is covered with a rainproof membrane.
[0011] Compared with the prior art, the present utility model has the following beneficial effects:
[0012] The terminal box of the present utility model is made of stainless steel material, enabling the box body to have anti-corrosion and rust-proof properties. The box body can operate stably in the outdoor environment for a long time. The terminal box is equipped with louvers, which not only ensure good ventilation effect to dissipate heat for the inverter, but also can effectively isolate dust and protect the cleanliness inside the inverter. The cutting parts, corner parts and welding parts of the terminal box are processed to make the surface smooth, and rubber rings are pasted at the corner parts. Waterproof materials are applied at the joints inside and outside the terminal box to ensure the waterproof performance of the terminal box. Description of the Drawings
