[0002] At present, AC contactors are widely used in low-voltage circuits. They are an industrial necessity that is safe to use, easy to control, and large in quantity and wide in scope. Their working principle is that when the contactor electromagnetic coil is not energized, the reaction force of the spring and the deadweight of the armature core keep the main contacts in the disconnected position. When the electromagnetic coil is connected to the control voltage (generally the rated voltage) through the control circuit, the electromagnetic force overcomes the reaction force of the spring to attract the armature to the static iron core, driving the main contacts to close, connecting the circuit, and the auxiliary contacts to move accordingly.
[0003] The AC contactor is generally provided with a spring support structure for spring support. The spring support structure generally includes a support frame and a spring seat. In the prior art, the spring seat is generally fixed at the bottom of the support frame, and then the spring is fixed on the spring seat. However, the elastic force of the spring will be damaged after a long period of use, that is, after deformation, the armature may not be able to attract the static iron core, which affects the service life of the entire AC contactor. Utility Model Content

Through the support frame and adjustment assembly that are set, in actual use, the position between the guide rod structure and the support frame can be adjusted, and reasonable adjustment can be made according to different positions based on the different elastic forces of the spring. When in use, the guide rod structure can be rotated, and the side block structure on the outside of the guide rod can pass through the side hole structure and be clamped with the bottom of the support frame to achieve a clamping effect. After the guide rod is clamped, the spring can achieve the characteristics of extension and contraction according to different side block positions, thereby extending the service life of the spring.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: including an AC contactor body, a constraint plate is arranged in the AC contactor, and multiple groups of support frames are arranged in the constraint plate, a positioning hole is opened in the middle of each group of support frames, a side hole is opened on one side of the positioning hole, an adjustment component is arranged in the positioning hole, and the adjustment component includes a guide rod, a side block arranged on the outside of the guide rod, a spring arranged at the top end of the guide rod and a pressure block arranged at the top end of the spring, and both ends of the spring are fixedly connected to the pressure block and the support frame respectively.
[0006] As a preferred technical solution of the utility model, the side hole is a fan-shaped structure, and a plurality of groups of the pressing blocks are arranged on the outside of the guide rod, and the size of each group of the pressing blocks is adapted to the size of the side hole.
[0007] As a preferred technical solution of the utility model, the pressing blocks are provided with at least four groups, and the pressing blocks in each group are evenly distributed on the outer side of the guide rod in a spiral upward direction.
[0008] As a preferred technical solution of the utility model, a hexagonal groove is provided at the top end of the guide rod.
[0009] As a preferred technical solution of the utility model, the height difference of each group of side blocks is adapted to the thickness of the support frame.
[0010] As a preferred technical solution of the utility model, the size of the pressing block is larger than the outer diameter of the spring.
[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:
[0012] 1. In this device, by setting up the support frame and adjustment components, in actual use, the position between the guide rod structure and the support frame can be adjusted, and reasonable adjustments can be made according to different positions based on the different elastic forces of the springs. When in use, the guide rod structure can be rotated, and the side block structure on the outside of the guide rod can pass through the side hole structure and be locked with the bottom of the support frame to achieve a locking effect. After the guide rod is locked, the spring can achieve the characteristics of extension and contraction according to different side block positions, thereby extending the service life of the spring.
[0013] 2. In the present device, the side block structure is equidistantly arranged on the outside of the guide rod in a spiral manner. Therefore, compared with the existing structure, when in use, the present device can be rotated and clamped through the hexagonal groove opened at the top of the guide rod. Since the spacing between each group of side blocks is adapted to the thickness of the support frame, when in use, the specific elastic force of the spring can be adjusted according to the angle difference between the side blocks. Compared with the existing structure, the present device has a lower use cost, a simple and reliable structure, and is easy to adjust. BRIEF DESCRIPTION OF THE DRAWINGS
