Background

According to the regulations of relevant national standards, the contacts of the electric appliance must be subjected to plugging and unplugging tests at a specific frequency. For example, for a cordless electric kettle, according to the relevant national standard, the electric kettle is required to be placed on a base and then taken down, and the operation is repeated 10000 times, so as to judge the service life of the contact.

Currently, in these contact life testing operations, testing is performed manually. The drawbacks of manual testing are obvious: firstly, the workload is huge, for example, 10000 times of plugging and unplugging are required in the contact life test of the cordless electric kettle; secondly, the counting accuracy is low, and because the whole process is long, manual counting is easy to generate errors; third, when a specific frequency is required, manual operation cannot meet the requirement of accurate frequency.

Detailed Description

In order that the invention may be better understood, we now provide further explanation of the invention with reference to specific examples.

As shown in fig. 1, the device for testing the service life of an electrical contact includes a base 2, a cylinder fixing support 1 is fixed on the base 2, and further includes a cylinder 6 and a cylinder fixing block 7, the cylinder 6 is fixedly connected with the cylinder fixing support 1 through the cylinder fixing block 7, a first fixing component is fixedly connected to the piston end of the cylinder 6, as shown in fig. 1, in this embodiment, the first fixing component preferably includes a fixing head 10 and a connecting rod 9, and the fixing head 10 is fixedly connected with the piston through the connecting rod 9.

As shown in fig. 1, the connecting rod 9 here is in the shape of a door, two fixing heads 10 being arranged at each end of the door-shaped connecting rod.

As shown in fig. 1, a second fixing assembly is fixed on the base 2, and the second fixing assembly comprises a fixing head 11 and a connecting seat 4.

In this embodiment, we take the electric kettle as an example, it can be seen that the base of the electric kettle is clamped and fixed by 3 times of the second fixing component, and the kettle body 5 of the electric kettle is clamped and fixed by the first fixing component. When the cylinder moves upwards, the first fixing component is driven to move upwards so as to drive the kettle body 5 to move upwards, and when the cylinder moves downwards, the first fixing component is driven to move downwards so as to drive the kettle body 5 to move downwards. When the kettle body moves downwards, the contact is closed, and when the kettle body moves upwards, the contact is opened. Therefore, the closing and opening states are simulated in the contact life detection.

With particular reference to fig. 2, it can be seen that the fixing head comprises a pressure piece 12, a press bolt shank 13, the pressure piece 12 being fixed to the top end of the press bolt shank 13, the bottom end of the press bolt shank 13 being formed with a thread.

As shown in fig. 2, in this embodiment, by taking the second fixing component as an example, the pressing bolt rod 13 is fixed in the connecting seat 4, and the position of the pressing bolt rod 13 can be changed through screw-thread fit, so as to adjust the degree of compression between the pressing block and the electrical appliance to be detected.

As shown in fig. 1 and 2, the compact is a circular compact in this embodiment. And with particular attention to fig. 1, the first fixing assembly comprises two oppositely disposed fixing heads and the second fixing assembly comprises two oppositely disposed fixing heads, and preferably the two fixing heads of the first fixing assembly are located at positions corresponding to the midperpendicular of the connecting line of the two fixing heads of the second fixing assembly.

Under this kind of fixed mode, fixed more firm, the test is more reliable and more stable.

In particular, with reference to fig. 1, we see that the cylinder fixed block is also provided with a counting device 8, which in this embodiment is an optical displacement sensor.
