[0024] like Figures 1 to 3 As shown, the utility model proposes a double-group common-action relay structure, including: a shell 1 and a base 2 arranged inside the shell 1, and the inner wall of the shell 1 is coated with an insulating coating, which can effectively prevent current leakage and improve the insulation performance of the relay, thereby ensuring the safety of the circuit. One side of the base 2 is provided with two implantable card slots 3; a magnetic circuit component for controlling the on-off of the circuit is clamped and arranged inside the implantable card slot 3, and the magnetic circuit component is located on one side of the base 2. The magnetic circuit component includes a wire rack 4 clamped and arranged inside the implantable card slot 3, and a yoke 5 is clamped and arranged on one side of the lower end of the wire rack 4, and the yoke 5 The other side is provided with a reference hole for automated precision collision assembly, a clamping block is fixedly provided on one side of the yoke 5, and the yoke 5 is an "L"-shaped structure, a through groove is provided on the bottom surface of the yoke 5, and a dynamic spring 6 is fixedly provided on one side of the yoke 5 through the clamping block, and a plurality of clamping holes are provided on the dynamic spring 6; a normally closed static spring 7 and a normally open static spring 8 are fixedly connected and arranged on one side of the base 2, and the upper ends of the normally closed static spring 7 and the normally open static spring 8 are arranged correspondingly, and the lower ends are staggered with each other, and the lower ends of the normally closed static spring 7 and the normally open static spring 8 are respectively fixedly provided with static spring terminals 9, and the static spring terminals 9 pass through the base 2 and extend to the outside for easy connection with the circuit.

[0025] like Figure 2 and Figure 3As shown, the magnetic circuit assembly also includes an armature 10 fixedly clamped on the movable spring 6, a clamping block corresponding to the clamping hole on the movable spring 6 is provided on the upper surface of the shell 1, and the armature 10 is located above the wire frame 4. An iron core 11 is provided below the armature 10, and the iron core 11 is fixedly passed through the wire frame 4 and extended to be fixedly connected with the through groove at the bottom of the yoke 5. The outer wall of the wire frame 4 is wound with an enameled wire 12, which can generate a magnetic field by passing current to realize the on and off of the circuit.

[0026] Furthermore, static contacts 13 are fixedly provided on corresponding surfaces of the normally closed static spring 7 and the normally open static spring 8, respectively. There are two groups of static contacts 13, and the static contacts 13 are symmetrically arranged in the upper and lower directions.

[0027] Secondly, the movable spring 6 is bent, and the bending part is in close contact with the upper side corner of the yoke 5. A movable contact 14 is fixedly provided at one end of the movable spring 6. The movable contact 14 is located between the static contacts 13 and can be stably connected to the static contacts 13 to achieve stable on and off of the circuit.

[0028] like Figure 3 As shown, a slot 15 is provided on one side of the lower end of the wire rack 4 to facilitate stable insertion of the yoke 5 and reduce the installation space occupied.

[0029] Furthermore, two groups of enameled wire terminals 16 are fixedly provided through the housing 1 , and the connecting ends of the enameled wire terminals 16 are respectively connected to the two ends of the enameled wire 12 , so as to facilitate circuit connection and generate a magnetic field.

[0030] In addition, an insert block 17 is fixedly provided on the normally closed static spring 7 and the normally open static spring 8 respectively, and the insert block 17 can make the normally closed static spring 7 and the normally open static spring 8 stably inserted on one side of the base 2.

When the magnetic circuit assembly is energized, the enameled wire terminal 16 transmits current to the enameled wire 12, creating a magnetic field that, in conjunction with the iron core 11, attracts the armature 10. The armature 10 then moves the movable spring 6, which in turn moves the movable contact 14, ensuring stable contact between the movable contact 14 and the static contact 13 on the normally closed static spring 7.

[0034] Furthermore, by replacing two relays with a single relay, while also providing forward and reverse control functions, costs and size are significantly reduced. Furthermore, the two electromagnetic assemblies share a corresponding set of normally closed and normally open static springs 7 and 8, eliminating two static spring terminals 9. This saves installation space, increases sensitivity, reduces power consumption of the enameled wire 12, and facilitates assembly, further reducing costs.

[0035] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
