Problems solved by technology

However, due to the limited space of the cam of the mechanical pressing device, generally only one needle bar can be arranged on the cam, so the mechanical pressing device can only test one microswitch device at a time. Test the next, obviously, the test is less efficient

Embodiment Construction

[0055] In order to better understand the technical solutions provided by the embodiments of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation manners.

[0056] The switching device life test device is used to test the service life of the switching device. The switching device includes a mechanical switching device. The switch device is such as a micro switch device. The following uses a micro switch as an example to briefly introduce the principle and process of testing the life of a switch device.

[0057] Please refer to figure 1 , the micro switch includes a housing 110, a mounting hole 110, a transmission element 130, a button 140, a hook 150, an action reed 160, a contact 170, a normally closed terminal 181, a normally open terminal 182 and a common terminal 183, and the mounting hole 110 is set On the shell 110, it is used to fix the micro switch on other devices. When no extern...

Abstract

The invention provides a testing device for the service life of switching elements. The testing device is used for improving the efficiency of the testing of service life of switching elements. The testing device comprises a main body, at least two fixed parts, a power part and a pressing part, wherein the at least two fixed parts, the power part and the pressing part are arranged in the main body; the at least two fixed parts are used for fixing at least two switching elements; the power part is connected with the pressing part and used for driving the pressing part to reciprocate toward a direction approaching the at least two switching elements and toward a direction away from the at least two switching elements; the pressing part is arranged above the at least two fixed parts; the pressing part applies pressure on the contacts of the at least two switching elements when the pressing part moves toward the direction approaching the at least two switching elements; and when the pressing part moves toward the direction away from the at least two switching elements, the pressure applied to the contacts of the at least two switching elements is released.

Description

technical field [0001] The present application relates to the technical field of switching device testing, in particular to a switching device life testing device. Background technique [0002] The switching device is used to control the switch of the household electrical equipment, for example, the switching device is used to control the opening or closing of the air conditioner. The switch device includes a micro switch device. The micro switch device usually includes a transmission element and an action reed. The working process of the micro switch device is roughly as follows. The external force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), so that the fixed contact and the movable contact on the action reed are quickly connected. When the force on the transmission element is removed, the action reed produces a reverse action force, and the reverse action is completed instantaneously, so that the micro switch is quick...
