Specifically, the stop block structure is in a block or column structure and the like; the upper end of lower casing 2 is towards last casing 1, and the lower extreme of lower casing 2 deviates from last casing 1, and one side that lower casing 2 deviates from last casing 1 is the lower extreme of casing 2 down promptly, that is to say, second connecting piece 21 sets up the lower extreme at casing 2 down. When the metering module fixing device is installed in the electronic control box 6, the metering module fixing device is usually fixed on a terminal board 61 in the electronic control box 6. Thus, the fixed connection between the metering module fixing device and the terminal board 61 can be realized through the splicing between the second connecting piece 21 and the terminal board 61, the structure is simple, and the installation is convenient.
Alternatively, as shown in fig. 3, 9 and 10, the terminal plate 61 is provided with a slot 611, the second connector 21 is inserted into the slot 611, and the second connector 21 is provided with a guide surface 211 for guiding the second connector 12 to be inserted into the slot 611.
The insertion groove 611 may be a polygonal groove, a circular groove, a U-shaped groove, or other geometric shape, and is not particularly limited in this embodiment. When the slot 611 is a polygonal slot, the slot 611 has a plurality of slot walls, and the guide surface 211 on the second connecting member 21 is an inclined surface structure, and the second connecting member 21 may have a plurality of guide surfaces 211; when the slot 611 is a circular slot, the slot 611 has a slot wall, and the guide surface 211 of the second connecting member 21 has a cambered surface structure. However, regardless of the shape of the slot 611, the distance between the guide surface 211 and the slot wall of the slot 611 increases in the direction in which the second connector 21 is inserted into the slot 611, i.e., the cross-sectional area of the end of the second connector 21 inserted into the slot 611 decreases in the direction in which the second connector 21 is inserted.
