Embodiment 1
[0034] Please combine Figure 1 to Figure 4 , the miniature circuit breaker includes a miniature circuit breaker main body 1, the outer cover of the miniature circuit breaker main body 1 is provided with a housing 2, the outer cover of the miniature circuit breaker main body 1 is provided with a housing 2, and the housing 2 is reserved for the miniature circuit breaker The wire harness opening (not shown) through which the wire harness of the main body 1 passes. One end of the casing 2 has an insertion opening (not marked) for inserting the miniature circuit breaker main body 1 . A box body 25 is provided at the end of the casing 2 away from the insertion port, and the box body 25 contains a cooling liquid, which in this embodiment may be water or liquid freon. The side of the box body 25 facing the insertion opening is provided with a heat conduction assembly in contact with the main body 1 of the miniature circuit breaker. The heat conduction component is used to transfer ...
Embodiment 2
[0051] Please combine Figure 5 to Figure 7 , the present embodiment 2 is an improved solution of embodiment 1, specifically, a bead groove 1 34 is provided on the docking block 28, and a top bead 32 is connected to the bead groove 1 34 through a spring 2 33, and on the groove wall of the docking groove 30 Offer the top groove two 31 that cooperates with top ball two 32. Wherein when the deformation of the second spring 33 did not occur, the bead center of the top bead 2 32 was flush with the notch of the bead groove 1 34 .
[0052] In this embodiment, when the docking block 28 is just inserted into the docking groove 30 , the top ball 2 32 will be pressed into the bead groove 1 34 and the spring 2 33 will be compressed after receiving the pressing force from the wall of the docking groove 30 . And when the docking block 28 is fully inserted in the docking groove 30, the position of the top ball 2 32 corresponds to the position of the top groove 2 31, and the top ball 2 32 is...
