Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, specifically a modified wiring structure for a sine wave inverter. Background Technology

[0002] A modified sine wave inverter is a device that converts direct current (DC) to alternating current (AC). Its output waveform is between a square wave and a sine wave. Modified sine wave inverters typically use PWM (Pulse Width Modulation) to generate the modified wave output. After the DC power enters the inverter, it is controlled by a dedicated intelligent circuit and a high-power MOSFET. Under the regulation of the control circuit, the DC current is switched on and off rapidly according to a certain pattern to generate a pulse sequence that approximates a sine wave. After filtering and other processing, it is shaped into a modified sine wave output.

[0003] Meanwhile, a modified sine wave inverter with a protective structure, disclosed in announcement number CN220254341U, includes a housing and electronic components disposed within the housing. Ventilation holes are provided at opposite ends of the housing, with the positions of the ventilation holes directly opposite the positions of the electronic components, so that airflow enters from one ventilation hole and flows out from the other ventilation hole, passing through the electronic components. The housing includes a base plate, and the modified sine wave inverter also includes a support assembly. The bottom of the support assembly is connected to the base plate, and the top of the support assembly is connected to the electronic components, so that the electronic components and the base plate are spaced apart.

[0004] The aforementioned modified sine wave inverter with protective structure lacks protection at the wiring ports during use. When exposed to liquids, liquids can easily seep in, causing damage to the wiring ports, resulting in short circuits and increased maintenance costs.

[0005] Therefore, a modified wiring structure for a sine wave inverter is proposed to address the above problems. Utility Model Content

[0008] Preferably, a limiting frame is fitted to the outer side of the connecting column, and the limiting frame is fixedly installed with the outer shell. A limiting plate is fixedly installed inside the outer shell, and a limiting groove is opened inside the limiting plate.

[0009] By adopting the above technical solution, the limiting frame plays a limiting role when the threaded rod is pushed in, so that it will not deviate when pushed in. At the same time, the limiting groove is set so that it can quickly find the correct position when connected.

[0010] Preferably, a protective shell is fitted to the outside of the outer shell, a groove is provided on the right side of the protective shell, a protective post is fixedly provided on the front side of the protective shell, a pipe is fixedly provided inside the protective post, and a rubber sleeve is fixedly provided on the outside of the pipe.

[0011] By adopting the above technical solution, when the connecting wire is connected, it is inserted into the pipe, and the rubber sleeve has an anti-slip function, making it more firmly fixed and preventing it from slipping. The protective post will not cause the pipe to crack when the connecting wire shakes, thus increasing its service life.

[0012] Preferably, a slot is provided on the front side of the device body, and a fixing slot is provided in the middle of the front side of the device body.

[0013] By adopting the above technical solution, and setting the slot and fixing slot, the protective shell is more firmly fixed around the outer shell, providing more comprehensive protection for the wiring structure.

[0014] Preferably, a circular hole is provided on the right side of the outer casing, and a display screen is fixedly provided on the top of the device body.

[0015] By adopting the above technical solution and setting a round hole, it is convenient to remove and place the threaded rod, and also convenient to replace the damaged structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses an outer shell to fix the wiring terminals inside, so that the wiring terminals are not exposed when wiring, thus protecting the wiring terminals. At the same time, a limiting frame is set to limit the threaded rod when it is pushed in, so that it does not deviate when pushed in. Additionally, a limiting groove is set to quickly find the correct position during connection.

[0018] 2. This utility model features a protective outer shell. By pressing a button, the buckle is engaged in the slot, and the fixing block enters the fixing groove, making the protective shell more firmly fixed around the outer shell. This provides more comprehensive protection for the wiring structure. When connecting the wires, the rubber sleeve has an anti-slip function, making it more secure and preventing slippage. The protective post will not cause the pipe to crack when the connecting wires shake, thus increasing the service life. Attached Figure Description
