[0033] Example 1

[0034] To ensure the quality of the air conditioner, a direct load test is required on the air conditioner electrical box. Currently, direct load testing of the air conditioner electrical box uses magnetic adsorption power claws and direct plug-in power claws. During operation, they are connected to the electrical box terminal board to power on. Then, the test terminals of components such as the outdoor fan, compressor, and electronic expansion valve are plugged into the pin sockets of the air conditioner electrical box to test the air conditioner electrical box. However, the above-mentioned power claws have the risk of unstable insertion between the electrical box component terminal board and the power claws, which may loosen and cause sparks. This can cause overcurrent damage to power devices such as the IGBT on the electrical box component mainboard.

[0035] Therefore, an electrical box power-on device is needed that can stably connect to the electrical box terminal board to avoid unstable and loose connection, which may cause overcurrent damage to power devices such as the mainboard IGBT of the electrical box components.

[0036] In response to the above problems, an embodiment of the present application provides an electrical box power-on device that can stably dock with the electrical box terminal board, avoiding the phenomenon of unstable and loose docking that may cause overcurrent damage to power devices such as the electrical box component mainboard IGBT.

[0044] The electrical appliance box power-on device of the embodiment of the present application comprises an electrical appliance box placement seat 1 and a power-on component 2;

[0045] The electrical box placement seat 1 is used to place the electrical box. For example, the electrical box is an air conditioner electrical box. The shape and size of the electrical box placement seat 1 are not limited in the embodiment of this application. According to actual applications, in order to make the electrical box placed more stably, the shape of the electrical box placement seat 1 can be set according to the shape of the electrical box.

The terminal block retaining groove 11 can play a role in limiting and positioning, allowing the terminal block to be quickly and accurately placed in the terminal block retaining groove 11.

[0047] The power-on component 2 includes a connected power-on probe 22 and an upper electric cylinder 21; that is, the power-on probe 22 is arranged at one end of the upper electric cylinder 21, and the upper electric cylinder 21 has a cylinder part and a telescopic rod part, that is, the power-on probe 22 is arranged at the telescopic rod part, and through the telescopic effect of the telescopic rod of the telescopic rod part, the upper electric cylinder 21 can be pushed out to make the upper electric cylinder 21 dock with the terminal board, completing the automatic power-on process, and because the upper electric cylinder 21 is electrically controlled, when the upper electric cylinder 21 is pushed out, after the power-on probe 22 docks with the terminal board, it can also stably control the power-on probe 22 to dock with the terminal board without loosening. When the power-on demand is completed, the upper electric cylinder 21 is electrically controlled, the retractable rod retracts, the power-on probe 22 is separated from the terminal board, and the power-off process is automatically completed.

[0048] The power-on assembly 2 is disposed on one side of the terminal block's limiting slot 11. The power-on assembly 2 is disposed on one side of the terminal block's limiting slot 11 to enable the power-on assembly 2 to interface with the terminal block without obstruction.

[0049] The beneficial effects of the embodiments of the present application include: an electrical box placement seat and a power-on assembly, wherein the electrical box placement seat is provided with a terminal block limiting slot; the terminal block limiting slot is used to place the terminal block of the electrical box. The power-on assembly includes a connected power-on probe and an upper electric cylinder; the power-on assembly is arranged on one side of the terminal block limiting slot. That is, when the terminal block is placed in the terminal block limiting slot, the upper electric cylinder pushes the power-on probe to dock the power-on probe with the terminal block. The upper electric cylinder can stably control the docking of the power-on probe and the terminal block, and the phenomenon of the power-on probe and the terminal block becoming loose is prevented. This avoids the sparking phenomenon caused by the loose power claws and the terminal block in the prior art, ensures the stability of the electrical box power-on, and ensures that the power components of the electrical box mainboard, such as the IGBT, will not be damaged by overcurrent during the electrical box testing process.

[0050] In addition, the power-on cylinder can automatically control the connection between the power-on probe and the terminal board, which further improves the test efficiency of the air-conditioning electrical box compared with the traditional method of manually connecting the power supply device to the terminal board of the air-conditioning electrical box to power on.
