Embodiment Construction

[0038] see figure 1 , the present invention discloses a test device 100, which is used to test a keyboard 200 (see Figure 4 ) reliability and service life. The testing device 100 includes a sleeve 10 , two stoppers 20 , a guide rod 30 , an elastic member 40 , a washer 50 , a first adjustment member 62 , a second adjustment member 64 , a pressure head 70 and a fixing member 80 .

[0039] The sleeve 10 is a hollow structure, and its outer peripheral wall is provided with several annular protrusions arranged at equal intervals. The two stoppers 20 are hollow cylinders, which are respectively fixed on the inner peripheral walls of the two ends of the sleeve 10 .

[0040] The guide rod 30 is slidably passed through the sleeve 10 , and a flange 32 is arranged around a substantially middle and lower portion of the guide rod 30 . The diameter of the flange 32 is slightly larger than that of the guide rod 30 . When the guide rod 30 passes through the sleeve 10 , the flange 32 abuts...

Description

technical field [0001] The invention relates to a test device, in particular to a test device for testing the reliability and life of a button. Background technique [0002] Before shipment, electronic products need to go through a series of reliability tests and life tests to ensure the quality of the products. Among them, the keys of the electronic product are used to execute various functions after the user presses them. Therefore, in the reliability test of the button, repeated pressing must be performed to predict whether the button will maintain a certain quality after a long time of use. [0003] A traditional testing device includes a slider, a thimble and a spring. The spring is sleeved on the slider and resists the thimble, and the thimble corresponds to a button. When the slider moves under the action of external force, the spring and the thimble are pushed, so that the thimble presses the button, and then the slider is reset by the restoring force provided by t...
