Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
A contactor capable of adjusting contact synchronization time comprises an electromagnetic base 1, a plurality of movable contact assemblies 2 and fixed contacts 3, wherein the movable contact assemblies 2 and the fixed contacts 3 are arranged in the contactor; an electromagnetic coil is installed in the electromagnetic base 1, the electromagnetic base 1 synchronously drives all the movable contact assemblies 2 to move, the plurality of fixed contacts 3 are respectively installed on the displacement path of the movable contact assemblies 2 in an opposite mode, and an adjusting device for adjusting the distance between the movable contact assemblies 2 and the fixed contacts 3 is installed in the movable contact assemblies 2.
And a support plate 5 is arranged on an electromagnetic push rod 4 of the electromagnetic base 1, and the movable contact assemblies 2 are all arranged on the support plate 5.
The adjusting device adjusts the theoretical distance between the movable contact assembly 2 and the fixed contact 3 through the adjusting screw 21, and the actual distance adjusted by the adjusting screw 21 is realized through the pushing of the spring 22 to the movable contact assembly 2.
One end of the adjusting screw 21 is arranged in the supporting plate 5, the spring 22 is sleeved on the screw, and the movable contact assembly 2 is arranged between the spring 22 and the positioning sleeve 25.
The movable contact assembly 2 comprises a movable contact 24, a groove is processed in the center of the movable contact 24 for placing a positioning sleeve, a through hole is processed in the center of the groove for a screw rod of the adjusting screw rod 21 to pass through, and bosses higher than screw caps are further arranged at two ends of the movable contact 24.
A positioning sleeve 25 is arranged between the adjusting screw 21 and the movable contact 24, the bottom centers between the two positioning sleeves are connected through a through pipe, one positioning sleeve is arranged in a groove on the movable contact 24, the other positioning sleeve is sleeved outside the spring 22, the through pipe is arranged in a through hole in the center of the movable contact 24, and the screw of the adjusting screw 21 is arranged in the through pipe.
