DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the embodiments and drawings.

[0020] In the embodiment, Figures 1 to 5 As shown, an electromagnetic relay is shown. The relay includes an electromagnetic drive component 1, an armature component 2 and a push piece 3, and also includes at least two sets of movable pieces 4 and static pieces 5 arranged in pairs, the movable piece 4 is provided with a movable contact 6, and the static piece 5 is provided with a static contact 7 corresponding to the movable contact 6, the armature component 2 drives the push piece 3 to move linearly, and the movable ends of all the movable pieces 5 move with the push piece 3, the movable piece 4 and the static piece 5 are installed on the base 8, and the wiring terminals of all the movable pieces 4 and the wiring terminals of all the static pieces 5 form two groups separated from each other in space. Specifically, the electromagnetic drive component 1 includes a coil 101 and an iron core 102 installed as one, the push piece 3 is arranged parallel to the axis of the coil 101, and a set of movable pieces 4 and static pieces 5 are respectively arranged on the base 8 corresponding to the push piece 3; the wiring terminal of one of the static pieces 5 extends along the axis of the coil 101 to be adjacent to the wiring terminal of the other static piece 5. This embodiment improves the structure of a static piece 5 to classify the connection terminals of the electromagnetic relay of multi-point control, so that the incoming and outgoing wires of the relay are centrally arranged, so as to better distinguish the incoming and outgoing wires, thereby avoiding signal confusion caused by wiring errors; it can also save wiring space, facilitate the beauty of wiring, and is suitable for application in certain specific occasions. Of course, the above purpose can also be achieved by changing the structure of a dynamic piece 4 so that the outgoing wires of the relay are centrally arranged.

[0021] In the embodiment, Figure 1 , 4 As shown, the base 8 is provided with an isolation groove 801 and a detachable isolation plate 9, an isolation channel is formed between the isolation plate 9 and the isolation groove 801, and the extension 501 of the static piece 5 is arranged in the isolation channel. The main function of the isolation channel of this embodiment is insulation isolation to prevent the static piece 5 from contacting with other moving pieces 4 or static pieces 5; the isolation channel can also tighten the static piece 5 to prevent it from loosening.

[0022] In the embodiment, Figure 2 , 3 As shown, L-shaped yokes 103 are symmetrically installed at both ends of the iron core 102; the armature assembly 2 is a lever structure whose middle part is hinged on the base 8 and is arranged between the two yokes 103; the armature assembly 2 has a push head 201, and a push groove 301 is provided in the middle of the push piece 3 corresponding to the push head 201, and a clamping groove 302 is provided at each end of the push piece 3 to cooperate with the moving piece 4. The structure of this embodiment can make the moving contact 6 and the static contact 7 maintain stable and reliable contact and separation, and has the advantages of rapid action and high reliability.

[0023] In the embodiment, Figure 2 , 5As shown, stacked shunt pieces 10 are installed on the moving piece 4, one end of the shunt piece 10 is fixed, and the other end is installed with a moving contact 6, the shunt piece 10 has an arched portion 1001, and a gap is maintained between the arched portions 1001 of adjacent shunt pieces 10. The shunt piece of this embodiment is made of metal with good electrical conductivity and is a structure with good elasticity. The shunt piece 10 is used for conducting electricity, shunting the original current on the moving piece 4, increasing the current carrying area of ​​the part, reducing the current density, and improving the conductive efficiency of the moving piece 4. The resistance heat generation of the moving piece 4 is reduced, and the arched portions 1001 of each layer of the shunt piece 10 are in a non-contact state, which increases the heat dissipation area and improves the heat dissipation performance, which has obvious advantages for the operation of equipment in a high temperature environment.

[0024] In the embodiment, Figure 5 As shown, the arched portion 1001 has a strip structure separated from each other. Since the shunt sheet 10 needs to be bent back and forth frequently, it is easy to produce cracks due to metal fatigue. In addition, the thickness of a single sheet is small and the tear resistance is poor. If a whole plate structure is used, once a small crack appears, the shunt sheet 10 will quickly break as a whole. This embodiment uses two separate strip structures. Even if one of them is cracked, the other will not be affected and can still work for a period of time, thereby extending the service life of the relay. In addition, the gap between the two strip structures can ensure that the shunt sheet 10 in the middle layer is in good contact with the air, further improving the heat dissipation performance.

[0025] In the embodiment, Figure 5 As shown, one end of the shunt sheet 10 with the moving contact 6 is connected and matched with the slot 302 of the push sheet 3. In this structure, the moving contact 6 and the push sheet 3 as a control element maintain a small distance, so that the action of the moving contact 6 can react more quickly and accurately with the push sheet 3, thereby improving the action sensitivity and accuracy of the relay.

[0026] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, and are not intended to limit the implementation methods of the present invention. Other obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
