[0019] As Figures 1-4As shown, a relay structure includes a shell body 1 and a conductive sheet, which in turn includes a continuous sheet 2, an end position sheet 3 and a contact position sheet 4, and it is pointed out that there is also an outer shell, and the above parts need to be pre-assembled and then assembled as a whole. This way is convenient to install, and also helps to improve the tightness of the parts connection and avoid large deviation caused by each link. The shell body 1 has a lower pressing contact surface 5 on the bottom surface, and the shell body 1 is also provided with an assembly base surface 6 parallel to the lower pressing contact surface 5, so that the middle part of the continuous sheet 2 is between the shell body 1 and the outer shell, similar to pressing flat, and also has good insulation performance. The assembly base surface 6 is the height suitable for external connection, and here it is not described and limited too much. Both ends of the continuous sheet 2 and one end of the end position sheet 3 and the contact position sheet 4 have a connecting end 7, which is on the assembly base surface 6, and the connecting end 7 is first inserted into the outer shell and then fixed, and then it is convenient to screw. Here, mainly to illustrate that the connecting end 7 is different from other parts. A plurality of anti-skid lines evenly arranged on the connecting end 7, the anti-skid lines are protrusions or depressions, and a screw can be used to strengthen the abutment at the terminal to prevent disconnection.

[0020] The end position sheet 3 and the contact position sheet 4 are also provided with a limiting sheet 8 and a moving contact sheet 9, the end position sheet 3 and the moving contact sheet 9 are fixed and abutted, the moving contact sheet 9 and the contact position sheet 4 are abutted, the shell body 1 is provided with a sliding groove 10 for the reciprocating movement of the limiting sheet 8, the limiting sheet 8 is abutted and linked with the moving contact sheet 9 on the moving path, the limiting sheet 8 is in S-shaped structure, and the limiting sheet 8 has a movable groove 11 at least on the inner side of one end. The movable groove 11 refers to the part that cooperates with the electric connection end 16 to slide, which can be the same in size, so that the two ends of the limiting sheet 8 can be replaced with each other, or not. In this embodiment, the moving contact sheet 9 and the contact position sheet 4 remain in contact connection, and the limiting sheet 8 can drive the moving contact sheet 9 to separate from the contact position sheet 4, so that the related circuit is disconnected. The linear movement of the limiting sheet 8 is generally driven by a coil magnetic field, and a magnetic attraction member 12 that can swing is provided, and the coil magnetic field makes it swing in a specified direction. At the same time, the magnetic attraction member 12 can be hooked with the limiting sheet 8, which is one of the embodiments and is not the only limitation. It can also be driven by other connecting rod methods, which will not be described too much here. The shape of the limiting sheet 8 is simple to process and produce, and the assembly is also convenient and reliable.

[0021] The limiting sheet 8 is also provided with a plug hole 13 at both ends for the insertion of the moving contact sheet 9, and the plug-in direction of the plug hole 13 is perpendicular to the moving direction of the limiting sheet 8.
