Description

Technical Field

[0001] This utility model relates to the field of inverter technology, specifically to an inverter with a hidden input terminal. Background Technology

[0002] An inverter is a power electronic device that converts direct current (DC) to alternating current (AC). It is widely used in solar power generation, electric vehicles, and UPS (uninterruptible power supplies). In use, it requires connection to a DC power source such as a battery pack or solar panel via terminals.

[0003] The terminals of current inverters are generally exposed and protruding, making them susceptible to moisture and corrosion, as well as damage from external impacts, which can lead to poor contact at the terminals. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention aims to provide an inverter with a hidden input terminal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An inverter with concealed input terminals includes a housing, terminals, an inverter circuit, and an output interface; the output interface is connected to the output terminal of the inverter circuit; the terminals include a positive terminal and a negative terminal, one end of which is connected to the positive input terminal and the negative input terminal of the inverter circuit, respectively.

[0007] The outer surface of the housing has two recesses, and each recess is equipped with a matching cover. The cover covers the corresponding recess and together with the corresponding recesses, forms a terminal receiving space. The other ends of the positive terminal and the negative terminal extend out of the housing and are located within the terminal receiving space formed by the two recesses and the corresponding covers. Each cover has a wire hole and each cover is detachably connected to the recess.

[0008] Furthermore, the outer edge of the cover is provided with at least one slot, the end of the slot facing the recess is an open structure, the inner wall of the recess is provided with a post corresponding to the position of the slot, the slot and the post both extend along the depth direction of the recess, and the post and the corresponding slot can be detachably inserted into each other.

[0009] Furthermore, the upper and lower parts of the cover are respectively provided with slots, and the upper slot and the lower slot are located on both sides of the cover; the slots are U-shaped, wherein the opening of the upper slot faces upward or downward, and the opening of the lower slot faces left or right.

[0010] Furthermore, the inverter also includes a terminal protection sleeve, with the other end of both the positive and negative terminals fitted with the terminal protection sleeve.

[0011] Furthermore, the terminal protective sleeve is made of plastic.

[0012] The beneficial effects of this utility model are as follows: By providing a recessed portion and a detachable cover, this utility model can effectively hide and protect the input terminal of the inverter, preventing it from being exposed or protruding to the outside, and effectively avoiding corrosion or impact on the terminal to affect its contact performance. Moreover, through the structural optimization of the cover, this utility model makes the cover easy to disassemble and install, and also less prone to falling off. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0018] This embodiment provides an inverter with concealed input terminal blocks, such as... Figure 1 As shown in Figure 3, the device includes a housing 1, terminals, an inverter circuit, and an output interface; the output interface is connected to the output terminal of the inverter circuit; the terminals include a positive terminal 2 and a negative terminal 3, one end of which is connected to the positive input terminal and the negative input terminal of the inverter circuit, respectively.

[0019] Two recesses 5 are provided on the outer surface of the outer casing 1. Each of the two recesses 5 is equipped with a matching cover 4. The cover 4 covers the corresponding recesses 5 and forms a terminal receiving space with the corresponding recesses 5. The other ends of the positive terminal 2 and the negative terminal 3 extend out of the outer casing 1 and are respectively located in the terminal receiving space formed by the two recesses 5 and the corresponding cover 4. Each cover 4 is provided with a wire hole 6, and each cover 4 is detachably connected to the recesses 5.

[0020] In this embodiment, the outer edge of the cover 4 is provided with at least one slot 7. The end of the slot 7 facing the recess 5 is an open structure. The inner wall of the recess 5 is provided with a post 8 corresponding to the position of the slot 7. Both the slot 7 and the post 8 extend along the depth direction of the recess 5. The post 8 and the corresponding slot 7 can be detachably inserted into each other.

[0021] More specifically, in this embodiment, the upper and lower parts of the cover 4 are respectively provided with slots 7, and the upper slot 7 and the lower slot 7 are located on both sides of the cover 4; the slot 7 has a U-shaped structure, wherein the opening of the upper slot 7 faces upward or downward, and the opening of the lower slot 7 faces left or right. With such a slot arrangement, the cover can be limited in the up, down, left and right directions, which facilitates the disassembly and installation of the cover and also prevents the cover from falling.
