Technical Field

[0001] The utility model relates to the technical field of leakage protection, in particular to a leakage protection plug life test stand. Background Art

[0002] Leakage current protection plugs are commonly used in household appliances. When a fault occurs, the plug immediately disconnects and cuts power, protecting personnel. China has established quality requirements for leakage current protection plugs. Therefore, before mass production, leakage current protection plugs must undergo aging testing in the laboratory. Each leakage current protection plug produced by a company varies, resulting in different test lifespans. This increases testing costs and wastes resources, leading to high costs and poor compatibility across lifespans. Utility Model Content

[0024] The following is combined with Figure 1-4 , the embodiments of the utility model are further described in detail.

[0025] A leakage protection plug life test stand 1, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes a support base 2, a plurality of power supply devices 3 spaced apart below the support base 2, and a plurality of pressing devices 4 spaced apart on the support base 2. A cavity for placing the power supply device 3 is provided in the support base 2, and the plug to be tested is plugged into the corresponding power supply device 3. Each plug corresponds to a pressing device 4. The pressing device 4 includes a first cylinder 41 for pressing the test key of the plug, a second cylinder 42 for pressing the test key of the plug, and a rotating block 43. The rotating block 43 is provided above the support base 2, and the rotating block 43 is provided with a rotating groove 431 that passes through the upper and lower sides along its circumference. The first cylinder 41 and the second cylinder 42 are both fixed on the rotating block 43, and the output shafts of the first cylinder 41 and the second cylinder 42 are both arranged to pass through the rotating block 43. The rotating groove 431 is used to adjust the positions of the first cylinder 41 and the second cylinder 42.

[0026] Multiple groups of pressing devices 4 can simultaneously perform repeated opening and closing operations on buttons of different plugs. The first cylinder 41 of each group of pressing devices 4 repeatedly presses the test key, and the second cylinder 42 repeatedly presses the test key. The first cylinder 41 and the second cylinder 42 can also adjust their positions according to the rotating block 43 to adapt to the differences in the positions of the test keys on different plugs, saving costs, improving compatibility, and increasing testing efficiency.

A through-hole 212 is provided between the two mounting slots 211. The mounting slots 211 communicate with the rotating slot 431 to secure the rotating block 43. The output shafts of the first and second cylinders 41, 42 are both located above the through-hole 212, resulting in a simple structure, easy installation and removal, and improved adjustment efficiency.

[0028] The rotating block 43 is configured as a disc structure, and the rotating groove 431 is configured as two arc-shaped groove structures symmetrical with the rotating block 43 as the center, which has higher adjustment efficiency and stronger bearing capacity of the rotating block 43.

[0029] An adapter 44 is rotatably connected to the output shaft of the first cylinder 41, and a pressing piece 45 for pressing the test key is provided on the side of the adapter 44 away from the first cylinder 41. The pressing piece 45 can be set as a columnar structure.

Bolts pass through the lifting adjustment slots 221 and are fixed in the fixing holes 213 to securely connect the support plate 21 and the vertical plate 22. The pressing device 4 can be adjusted horizontally and vertically, providing greater compatibility.

[0033] Please refer to Figure 1 、 Figure 2 The power supply device 3 includes a mounting base 31 fixed to the base 23. The mounting base 31 is provided with a plurality of upwardly-opening fixing slots 32 along its length. These fixing slots 32 are used to mount the sockets that power the plugs. A corresponding set of pressing devices 4 is positioned above each fixing slot 32. This facilitates securing the plugs, ensures the stability of the relative position of the plugs and their corresponding pressing devices 4, and improves the efficiency and accuracy of the test. The sockets and plugs are not shown in the figure.

[0034] Insert the plug to be tested into the socket and adjust the positions of the first cylinder 41 and the second cylinder 42 so that the first cylinder 41 is above the test button and the second cylinder 42 is above the test button. The second cylinder 42 activates the test button, while the first cylinder 41 presses the reset button, causing the plug to be repeatedly powered on and off. The number of power-on and power-off cycles it can withstand is used to record its service life.
