Description

Technical Field

[0001] The utility model relates to the technical field of micro inverters, in particular to a micro inverter equipped with a quick-install wire fixing buckle. Background Art

[0002] Currently, there are three ways to thread and fix the wires of traditional micro inverters. The first is to wrap the wires with wire ties and press them into the holes of the mounting parts. The second is to fix the wires through cable fixing heads. The third is to install and fix them on the mounting parts through hollow nuts and sealing rings.

[0003] Among the above three methods, method one can realize the rapid penetration installation of wires, but it cannot achieve waterproofing; method two can achieve waterproofing after the wires are installed, but the price is relatively high and the installation is time-consuming; method three requires the installation parts to have corresponding structures, which is limited by the implementation conditions. Utility Model Content

[0004] In view of the above situation, the utility model has been studied and improved to provide a micro inverter with a quick-install wire fixing buckle, which can realize the quick perforation and fixing of the wires and enable the inverter to achieve waterproof function.

[0005] In order to solve the above technical problems, the utility model provides a micro inverter equipped with a quick-release wire fixing buckle, comprising a housing, a cover plate, a circuit board assembly, and a quick-release wire fixing buckle (14). A portion of the rear portion of the quick-release wire fixing buckle is located inside the housing and connected to the circuit board assembly, and is connected to the quick-release wire fixing buckle through an insertion piece and a portion of the rear portion of the quick-release wire fixing buckle, so that the quick-release wire fixing buckle is located outside the housing.

[0006] As a preferred embodiment of the present invention, the quick-install wire fixing buckle is formed by integrally injection molding the wire as an insert.

[0007] As a further preferred embodiment of the present invention, the quick-install wire fixing buckle includes a wire, a fixing buckle injection-molded body, a sealing ring and an insert, the fixing buckle injection-molded body is located outside the shell, and the sealing ring and the insert are located inside the shell.

[0008] As a further preferred embodiment of the present invention, the fixing buckle injection-molded body includes a flange, a shaft, a sealing ring groove and an insert groove.

[0009] As a further preferred embodiment of the present invention, in the quick-install wire fixing buckle, the sealing ring is installed in a sealing ring groove of the fixing buckle injection molding body.

[0010] As a further preferred embodiment of the present invention, the insert is installed in an insert slot of the injection-molded body of the fixing buckle.

[0011] As an improvement of the present invention, a WiFi antenna is also installed and connected to the outside of the shell, and a portion of the rear portion of the WiFi antenna is embedded in the shell and connected to the circuit board assembly.

[0012] The structure of the utility model can realize the rapid perforation and fixation of the electric wires and enable the inverter to realize the waterproof function. BRIEF DESCRIPTION OF THE DRAWINGS
