[0034] An embodiment of the utility model provides an inverter terminal testing and plugging device.

[0035] Figure 1 FIG. 1 is a module structure diagram of an inverter terminal test plugging and unplugging device according to an embodiment of the present invention. Figure 1 As shown, an inverter terminal test plugging and unplugging device according to one embodiment includes:

[0036] base 100;

[0037] One or more plugs 101 provided on the base 100;

[0039] like Figure 1 As shown, the plug 101 is set on the base 100. The tester can operate the base 100 to connect the plug 101 with the terminal of the inverter to achieve plugging or unplugging at one time.

[0040] The spacing design size of the plugs 101 is adapted to the terminals of the inverter.

[0041] Preferably, if Figure 1 As shown, the inverter terminal test plugging device of one embodiment further includes:

[0042] Handle 102 is provided to facilitate operation by the tester to connect and disconnect the inverter terminals. In the disclosed embodiment, the plug 101 is selected based on the inverter terminals. Generally, high-voltage insulation testing is primarily performed on the inverter's H4 terminal, and the corresponding plug 101 can be a male or female plug that matches the H4 terminal.

[0043] As one of the preferred embodiments, the plug 101 includes a PV male plug and a PV female plug;

[0044] The PV male connector is used to plug the PV female terminal of the inverter, and the PV female connector is used to plug the PV male terminal of the inverter.

[0045] The inverter terminals include PV female terminals and PV male terminals, which are sealed according to the PV male and PV female terminals on the base 100 that are adapted to the size and position of the inverter terminals.

[0046] As one of the preferred embodiments, the PV male connector includes a chamfered concave head and a sectioned side.

[0047] The PV female connector includes a chamfered head.

[0048] The PV female connector features a chamfered head to compensate for dimensional tolerances in the inverter structure, facilitating faster installation. The PV male connector also features a concave head with chamfered corners and a profiled side profile to effectively prevent misalignment caused by inverter terminal tolerances and ensure connection reliability.

[0049] The center spacing of the mounting holes of the PV male connector and the PV female connector is designed according to the specifications of the inverter terminal model.

[0050] The plug 101 is made of a soft conductive material. Preferably, the plug 101 is made of copper.

[0052] The electrical connection structure is used to establish electrical connections between different plugs 101.

[0053] Preferably, the base 100 adopts a countersunk hole design, the connector is fixed by screws, and adjacent plugs 101 are connected using ordinary wires to achieve a series conduction effect. Therefore, the electrical connection structure can use ordinary wires set based on the base 100.

[0054] As one of the embodiments, in order to solve the universality problem of high-voltage insulation testing of different types of inverters, the embodiment of the present disclosure provides an inverter terminal testing and plugging device of a preferred embodiment.

[0055] Figure 2 FIG. 1 is a module structure diagram of an inverter terminal test plugging device according to a preferred embodiment. Figure 2 As shown, the inverter terminal test plugging device of a preferred embodiment further includes:

[0056] A moving mechanism 200 provided on the base 100;

[0057] The plug 101 is provided on the moving mechanism 200 to facilitate position change.

[0058] like Figure 2 As shown, the plug 101 is not directly provided on the base 100 but is provided on the moving mechanism 200. According to the cooperation between the moving mechanism 200 and the base 100, the position of the plug 101 is changed to adapt to different types of inverter terminals.

[0059] The moving mechanism 200 can realize movement on the base 100 or movement of the plug 101 .

[0060] As one of the optional embodiments, the moving mechanism 200 includes:

[0061] one or more moving tracks;

[0062] The plug 101 can be movably arranged on the movable track.

[0064] The moving mechanism 200 includes:

[0065] one or more moving tracks;

[0069] One or more connectors;

[0070] Wherein, one of the plugs 101 can be fixedly mounted on one of the connecting seats.

[0071] Among them, multiple connection sockets can be arranged in an array, and the plug 101 can be selected and fixed according to the actual size of the inverter terminal to form an appropriate fit. At the same time, based on the design of the connection socket, it is easy to replace the plug 101 of different sizes to adapt to the size changes of the inverter terminal.

[0072] As another preferred embodiment, the base 100 is a base made of a flexible material.

[0073] According to the selection of the flexible material, the base 100 has flexibility and can be deformed accordingly to facilitate compensating for the dimensional tolerance of the inverter structure.

[0074] Preferably, the base is a U-type plastic base.

[0075] The inverter terminal test and plugging device of the disclosed embodiment includes a base 100 and one or more plugs 101 disposed on the base 100.
