[0002] At present, in all aspects of people's daily life, in order to achieve the connection between electrical input and output, electrical connectors are often used. The common ones mainly include plugs, sockets, and MC connectors. These connectors have different numbers of contacts according to the number of phases of transmitted power or transmitted current. In various electronic products, these electrical connectors are widely used and are the main functional components of electronic products. A common electrical connector generally includes a male end and a female end. When the male end and the female end are connected together, the electrical connection is turned on, and when the male end and the female end are separated, the electrical connection is turned off. After the electrical connector is manufactured, it is usually necessary to perform plugging and unplugging tests on the electrical connector to obtain relevant information such as the service life of the electrical connector.

[0003] For example, the patent document with the publication number "CN102680152A" discloses a test device for the plugging and unplugging force of electrical connector contacts in a high-temperature environment.

The electromagnetic induction heating device is used to heat the contacts to a specified temperature; the driving device drives the right mechanical clamping device to move through the mechanical transmission device to realize the plugging and unplugging movement of the contacts; the force measuring device then collects data. However, under some test conditions, it is necessary to test the bearing capacity of the electrical connector under the action of plugging and unplugging forces in different directions. However, in the above patent technology, the direction of the plugging and unplugging force applied to the electrical connector cannot be adjusted, resulting in the operator being unable to obtain comprehensive test results.
