[0029] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 4 As shown: an eccentric assembly mechanism is used for assembling the moving contact bridge of the contactor or for simultaneous loading in a narrow structural space. The eccentric assembly mechanism includes: a base, a first driving source 1, a second driving source 2 and an eccentric loading component 3.

[0032] The base is made by connecting metal structural parts. Specifically, a first long strip hole (not marked in the figure) is opened on the base, and a second long strip hole (not marked in the figure) is opened on the corresponding contactor assembly machine (the size of the prior art is not repeated), and then the fasteners are sequentially penetrated in the first long strip hole and the second long strip hole to set the base on the corresponding contactor assembly machine. The number of the first long strip hole and the second long strip hole is the same, and there can be multiple. When replacing the same type of moving contact bridge assembly parts, it can be used almost without changing the overall structure. The effect is more significant especially when the electronic products are updated and replaced quickly. For example, when replacing the CJ10-20 permanent magnet AC contactor with the NSFC10 permanent magnet AC contactor, it is only necessary to unscrew the fasteners and adjust the relative installation position between the base and the contactor assembly machine to change the distance between the eccentric feeding component 3 and the AC contact, so that different moving contact bridges can be clamped and assembled.

Of course, in order to further control the accuracy, a second sensor is provided at the other end of the servo motor, and the rotation angle is monitored by the second sensor.
