When the second sub-housing 212 moves toward the side close to the first communication member 120 until the side of the first sub-housing 211 close to the first communication member 120 abuts against and contacts the limiting portion 112, the first energy storage power source 200 and the second energy storage power source 200 complete parallel operation. In addition, the first energy storage power supply 200 and the second energy storage power supply 200 can ensure that the second housing 210 and the first housing 110 are installed in place through the limiting effect of the limiting part 112 in the parallel operation process, so as to ensure that the second communication part 220 on the second sub-housing 212 is connected with the first communication part 120 on the first housing 110, and in addition, because the first sub-housing 211 and the second sub-housing 212 are arranged in a stacked manner and fixed in a staggered manner, the limiting part 112 can also stop the relative movement of the second housing 210 and the first housing 110 in the stacking direction, so as to avoid the connection failure between the communication parts caused by the fact that the second housing 210 is separated from the first housing 110.
As shown in fig. 1, in the present embodiment, the first connection assembly 10 further includes a cover plate 130 and a first elastic member 131, one end of the first elastic member 131 is connected to the bottom of the movable cavity 111, the other end of the first elastic member 131 is connected to the cover plate 130, the cover plate 130 can open or close the opening, and when the cover plate 130 closes the opening, the movable cavity 111 of the first housing 110 can be hidden and shielded by the cover plate 130; the second sub-housing 212 moves towards a side close to the first housing 110 to be in abutting contact with the cover plate 130, so that the cover plate 130 moves towards a side close to the first housing 110 synchronously and compresses the first elastic element 131, and the first elastic element 131 is used for providing a resetting force for the cover plate 130 to move towards a side away from the first housing 110.
When the second housing 210 is assembled with the first housing 110, the second housing 210 is aligned with the opening, then the second housing 210 moves toward the side close to the first housing 110 along the stacking direction until the second housing 210 contacts the cover 130 in a propping manner, then the second housing 210 continues to move toward the side close to the first housing 110 along the stacking direction, so as to force the cover 130 to move toward the side close to the first housing 110 synchronously, in this process, the cover 130 compresses the first elastic member 131 to enable the first elastic member 131 to store energy continuously, then the second housing 210 moves toward the side close to the first communication member 120 along the movable cavity 111 until the side close to the first communication member 120 of the first sub-housing 211 contacts the limiting portion 112 in a propping manner, at this time, the second housing 210 and the first housing 110 are installed in place, and the second communication member 220 on the second sub-housing 212 is connected with the first communication member 120 on the first housing 110, moreover, the second housing 210 can be always contained in the movable cavity 111 under the limiting action of the limiting part 112, so that connection failure between communication pieces caused by the fact that the second housing 210 is separated from the first housing 110 is avoided.
When the second housing 210 is disconnected from the first housing 110, the second housing 210 is moved along the movable cavity 111 toward the side away from the first communication member 120 until the second housing 210 is aligned with the opening, and then the second housing 210 is moved along the stacking direction toward the side away from the first housing 110 until the second housing 210 is separated from the cover 130, in which process, the first elastic member 131 continuously releases energy to enable the cover 130 to synchronously move toward the side away from the first housing 110 until the cover 130 is reset. In order to prevent the cover plate 130 from coming out of the opening, besides that the cover plate 130 is connected with the first housing 110 through the first elastic element 131, a stop strip may be added on the cover plate 130, and a stop groove is added on the first housing 110, in which the stop strip is slidably disposed, so as to limit the movement of the cover plate 130 towards the side away from the first housing 110 through the cooperation of the stop strip and the stop groove.

In addition, in order to allow the second housing 210 to be accommodated in the movable cavity 111 through the opening, the size of the whole waist shape formed by the orthographic projections of the first sub-housing 211 and the second sub-housing 212 in the stacking direction needs to be slightly smaller than the size of the waist shape of the limiting portion 112, and in order to allow the second housing 210 to move along the movable cavity 111, the size of the waist shape of the first housing 110 needs to be larger than the size of the whole waist shape formed by the orthographic projections of the first sub-housing 211 and the second sub-housing 212 in the stacking direction. It should be noted that the size of the waist shape of the first housing 110 and the size of the waist shape formed by the orthographic projection of the first sub-housing 211 and the second sub-housing 212 in the stacking direction should be limited by the limiting portion 112 (the side close to the first communication member 120) being capable of limiting the relative movement between the second housing 210 and the first housing 110 in the stacking direction.
