[0032] As Figure 1 And Figure 2 The utility model an embodiment of a new energy storage equipment with electromagnetic relay, including relay body 1, clamping assembly 2 and radiating assembly 3.

[0033] As Figure 1 And Figure 2 The relay body 1 includes the housing 11, and the housing 11 is detachably installed with the mounting plate 12, and the mounting plate 12 is installed with a plurality of wiring feet 13, and the wiring feet 13 are inserted in the mounting hole to install the relay in the power system.

[0034] Preferably, the outer wall of the terminal 13 is provided with an anti-oxidation coating by electroplating. The coating prevents the terminal 13 from oxidizing during long-term use, so as to ensure good contact between the terminal 13 and the electrical components in the mounting hole.

[0035] like Figures 5-7 As shown, the clamping assembly 2 includes multiple clamping rods 21. These multiple clamping rods 21 are movably mounted on the two side walls of the narrow side of the connector pin 13, with one end of each clamping rod 21 positioned on the outside of the connector pin 13. By providing multiple clamping rods 21 on the side walls of the narrow side of the connector pin 13, after the connector pin 13 is inserted into the mounting hole, the interaction between the clamping rods 21 and the inner wall of the mounting hole ensures a tight fit between the connector pin 13 and the mounting hole, thereby ensuring good contact after installation.

[0036] like Figure 6 Combination Figure 7 As shown, multiple locking rods 21 are provided on both sides of the narrow side of the terminal 13. The multiple locking rods 21 can increase the force exerted on the mounting hole, ensuring that the terminal 13 is inserted into the mounting hole without loosening. The locking rods 21 are made of copper, so that they can conduct electricity with each other when in contact with the inner wall of the mounting hole.

One end of the locking rod 21, which is placed in the sliding groove 22, is fixedly connected to the side wall of the elastic block 23. Since the elastic block 23 can deform, it can be compressed by squeezing it. The compressed elastic block 23 will have elastic force, so that when the locking rod 21 compresses the elastic block 23, the elastic block 23 will have a pushing force on the locking rod 21. Thus, under the action of the elastic block 23, when the locking rod 21 acts on the inner wall of the mounting hole, it will exert a certain force on the inner wall of the mounting hole, making the locking rod 21 and the inner wall of the mounting hole tightly connected.

[0039] like Figure 6 Combination Figure 7 As shown, a limiting ring 25 is fixedly connected to the inner wall of the opening of the sliding groove 22. The end of the snap-fit ​​rod 21 away from the elastic block 23 is slidably connected to the limiting ring 25 in a through manner, so that the end of the snap-fit ​​rod 21 away from the elastic block 23 can act in the mounting hole.

When the wedge-shaped portion 26 contacts the side wall of the mounting hole when the terminal pin 13 is inserted into the mounting hole, the clamping rod 21 can be compressed and retracted into the sliding slot 22 under the action of the wedge-shaped portion 26, so that the elastic block 23 has an outward pushing force on the clamping rod 21, and the end of the clamping rod 21 provided as the wedge-shaped portion 26 acts on the inner side wall of the mounting hole, and the plurality of clamping protrusions 24 increase the force of the clamping rod 21 acting on the inner side wall of the mounting hole, ensuring that the terminal pin 13 is tightly inserted into the mounting hole.

[0042] As Figure 3 and Figure 6 shown, the terminal pin 13 is provided with a fixing hole 27, and the inner side wall of the fixing hole 27 is provided with a magnetic attraction layer 28. The fixing hole 27 allows the terminal pin 13 to be stably inserted into the mounting hole, and the magnetic attraction layer 28 on the inner side wall of the fixing hole 27 further improves the stability after installation.

[0043] As Figure 1 and Figure 4 shown, the heat dissipation assembly 3 includes a plurality of heat dissipation holes 31, and the plurality of heat dissipation holes 31 are respectively arranged on the wall plates on the left and right sides of the shell 11. The heat dissipation holes 31 on the left and right sides of the shell 11 realize the convection of air in the shell 11, so that the hot air in the shell 11 can be discharged to reduce the temperature in the relay.
