Problems solved by technology
For many manufacturers of contactors, most manufacturers still manually connect the contactor terminals for the test of H400 contactors, and the manual connection takes a long time and the connection error rate is high
In particular, the H400 contactor has many terminals. In the case of a load test, the manual workload will increase sharply, and the error of the test result will be large.

Embodiment Construction
[0014] Test fixture of the present invention is controlled by pneumatic transmission control system (such as figure 1 shown) and fixture clamping mechanism (such as figure 2 shown) composition. When the pneumatic transmission control system is working normally, the protection system is intact, and the fixture clamping mechanism starts to work normally.
[0015] Such as figure 1 , 2 As shown in , the method of testing the H400 contactor 24 using the pneumatic transmission control system is to first turn on the air compressor 1 and reach the required pressure through the pressure reducing valve 5. Air pressure makes it work, and then adjusts the second flow control valve 18 to control the speed at which the cylinder piston pushes the clamping mechanism 22 to the product end of the H400 contactor 24. When the clamping mechanism 22 reaches the product end of the H400 contactor 24, it simultaneously controls the first Reversing valve 9 and the 3rd reversing valve 11 work; Adju...

The invention discloses a method for testing an H400 contactor by use of an air pressure transmission control system. An air compressor is started, at the moment, a second reversing valve starts to work for supplying air pressure to a third cylinder so as to enable the third cylinder to work, then the speed of a second flow control valve controlling a cylinder piston to push a clamp clamping mechanism to reach a product end of the H400 contactor is adjusted, and when the clamp clamping mechanism reaches the product end of the H400 contactor, a first reversing valve and a third reversing valve are simultaneously controlled to work; after product testing is completed, the air compressor stops working, a safety valve is open to discharge gas in a gas tank, the third reversing valve and the first reversing valve are turned off, a clamping element at a binding post end of the clamp clamping H400 contactor returns to an initial position, then the second reversing valve is turned off, and the clamp clamping mechanism returns to an initial position; and a test clamp finishing work. According to the invention, a clamping element structural design of a stud type binding post product is employed, the clamp is pushed by use of a conventional air pressure system to realize a product clamping function, and the efficiency, the reliability and the stability are high.
Description
technical field [0001] The invention relates to a method for testing an H400 contactor, in particular to a method for testing a testing end of an H400 contactor by using a clamping mechanism directly controlled by a pneumatic transmission. Background technique [0002] With the development of technology, H400 contactors are used in many fields, and H400 contactors need to be tested. For many manufacturers of contactors, most manufacturers still manually connect the contactor terminal for the test of H400 contactors, and the manual connection takes a long time and the connection error rate is high. In particular, the H400 contactor has many terminals. In the case of a load test, the manual workload will increase sharply, and the error of the test result will be large. Contents of the invention [0003] The technical problem to be solved by the present invention is: the method of testing the H400 contactor by using the pneumatic transmission control system to directly contr...
