The design is such that when the electric slide 33 moves downward, the driving block 36 presses the transition piece 531 under the gravity of the counterweight block 35, and the driving switch completes the action. Even if the electric slide 33 continues to move downward at this time, the driving block 36 will stop moving due to the action of the guide rail guide block 34, effectively preventing the switch from being damaged due to excessive pressing. At the same time, since the counterweight block 35 takes into account that the transition piece is made of plastic material, the driving block 36 is also made of plastic material, which can better protect the transition piece 531 during the pressing process.

The connecting piece 452 is inserted into the cavity of the static sheet assembly clamping block 46 and connected to an external controller through a lead hole on the static sheet assembly clamping block 46. With such a design, the experimental system can firmly clamp the static sheet assembly, and can also measure the contact pressure, i.e., the contact pressure, between the dynamic silver point 661 and the static silver point 451 through the dynamic force sensor 48. At the same time, the experimental system can adjust the position of the thrust baffle 44 by adjusting the manual slide 43, so as to adjust the motion end point of the driving assembly 53 and the rotation angle of the transition piece 531.

The connecting piece 68 is made of insulating material, and the movable plate assembly clamping block 67 is made of copper.

[0036] This experimental system is provided with a static piece assembly clamping block 46, a dynamic piece assembly clamping block 67 and a driving assembly clamping block 54, which can realize the separate clamping and fixation of the components related to the action in the manual switch product. The position can be adjusted and the installation can be blind-inserted. At the same time, it involves 8 parts in the manual switch product, including the static silver point 451, the connecting piece 452, the dynamic silver point 661, the rocker 662, the supporting piece 663, the transition piece 531, the spring 532 and the pin 533. Combined with the electric slide 33, it can realize the direct use of the dynamic piece assembly, the static piece assembly and the driving assembly in the manual switch product to carry out the manual switch electrical performance simulation experiment, ensuring the maximum similarity with the original manual switch product action process.

[0037] Specific implementation method 2: The static piece assembly clamping block 46 and the dynamic piece assembly clamping block 67 described in this implementation method are both made of copper, so that the static piece assembly 45 inserted into the static piece assembly clamping block 46 and the dynamic piece assembly 66 inserted into the dynamic piece assembly clamping block 67 still have good electrical conductivity, and are easy to connect with the controller by wire.

Thus, a manual operation is completed. The action of the switch; at this time, the electric slide 33-1 turns to move upward, and the electric slide 33-2 starts to move downward, so that the moving silver point 661 at the A end of the transition piece 531, that is, the non-pressing end, and the static silver point 451 change from being connected to being disconnected, and the moving silver point 661 at the B end of the transition piece 531, that is, the pressing end, and the static silver point 451 change from being disconnected to being connected, thus completing a manual switch action, at this time the electric slide 33-2 turns to move upward, and the electric slide 33-1 starts to move downward; in this way, the switching process of the simulated manual switch is realized.

[0045] Step 7: The contact pressure, i.e., the contact pressure, between the moving silver point 661 and the static silver point 451 is measured by the dynamic force sensor 48, and the positive pressure of the driving component 53 on the moving plate component 66 is measured by the dynamic force sensor 56; the real-time monitoring data of the contact pressure, contact voltage, and contact current between the moving silver point 661 and the static silver point 451 during each switching process are obtained by the controller, and the curves of the number of actions and the contact pressure, contact voltage, and contact current are obtained.

When the electric slide (33-1) moves downward, the driving block (36) presses the transition piece (531) under the gravity of the counterweight block (35), driving the pin (533) to press the seesaw (662), so that the moving silver point (661) at the A end of the transition piece (531), i.e., the pressing end, and the static silver point (451) are changed from disconnected to connected, and the moving silver point (661) at the B end of the transition piece (531), i.e., the non-pressing end, and the static silver point (451) are changed from connected to disconnected. This completes A manual switch action is performed; at this time, the electric slide (33-1) turns to move upward, and the electric slide (33-2) starts to move downward, so that the moving silver point (661) at the A end of the transition piece (531), i.e., the non-pressing end, and the static silver point (451) change from being connected to being disconnected, and the moving silver point (661) at the B end of the transition piece (531), i.e., the pressing end, and the static silver point (451) change from being disconnected to being connected, thus completing a manual switch action, at this time, the electric slide (33-2) turns to move upward, and the electric slide (33-1) starts to move downward; in this way, the switching process of simulating a manual switch is realized; Step 7: The contact pressure, i.e., the contact pressure, between the moving silver point (661) and the static silver point (451) is measured by the dynamic force sensor (48); the positive pressure of the driving component (53) on the moving plate component (66) is measured by the dynamic force sensor (56); the real-time monitoring data of the contact pressure, contact voltage, and contact current between the moving silver point (661) and the static silver point (451) during each switching process is obtained by the controller, and the curves of the number of actions and the contact pressure, contact voltage, and contact current are obtained. Based on the above-mentioned detection signals, the welding force, collision force, surge width t, I 2 t, peak current I PEAK , contact resistance, bounce energy, arcing energy, bounce times, bounce time, and using an industrial camera (65) to assist in observing the action process of the manual switch product; Step 8. Repeat steps 4 to 7 to obtain the electrical performance simulation experiments and corresponding experimental data of the static plate assembly, the moving plate assembly and the driving assembly of the manual switch product under different assembly relationships and when the driving assembly is subjected to different driving parameters. The experimental data will be used for experimental research on the influence of the assembly relationship of the static plate assembly, the moving plate assembly and the driving assembly in the manual switch and the user's pressing state on the product's anti-welding ability and electrical life, so as to determine the key factors affecting the anti-welding ability of the manual switch product, and ultimately improve the anti-welding ability and electrical life of the manual switch product.
