At the same time, a clamping pin 118 is provided on the bottom plate 111 at a position corresponding to the clamping groove 52, and the top of the clamping pin 118 also expands outward to form a flange. During assembly, the partition 50 is first placed on the bottom plate 111, and then the locking pin 118 is allowed to enter the locking groove 52 from the opening portion 521. After the locking pin 118 enters the locking portion 522, the partition 50 is moved forward so that the locking pin 118 falls into the depth of the locking portion 522. At this time, the flange on the top of the locking pin 118 will limit the up and down movement of the partition 50, and the locking pin 118 will not easily fall out of the locking groove 52.

[0065] At the same time, the top edge of the partition 50 is folded to the left to form a positioning flange 53, and the positioning flange 53 is provided with a fourth positioning hole 531. Figure 4 A fourth positioning pin 135 is provided at a position of the top cover 13 corresponding to the partition 50, and the fourth positioning pin 135 can be inserted into the fourth positioning hole 531, so as to position the top of the partition 50. After the partition 50 is positioned, the locking hole 30 on the top cover 13 corresponding to the partition 50 can be aligned with the locking hole 30 on the positioning flange 53 of the partition 50, and then it can be locked by fasteners.

[0066] In addition, the housing of the electrical component further includes a front plate 14 and a panel 15. After positioning and assembling the rear plate 12, the top cover 13 and the partition 50 of the housing, the assembly of the front plate 14 can be completed relatively simply. In this embodiment, a structure similar to the snap-fit ​​groove 52 on the partition 50 is provided on the front plate 14, which can be pre-positioned during assembly through the cooperation of the snap-fit ​​groove 52 and the snap-fit ​​pin 118.

[0067] In the electrical assembly provided by the present invention, a shell is provided for installing electrical components, and the shell includes a base 11 and a rear plate 12. The locking holes 30 provided on the two can be aligned and locked by fasteners. However, in actual applications, the alignment of the locking holes 30 requires multiple people to operate, which is inconvenient. Therefore, a bottom plate 111 and a bottom side plate 112 are provided on the base 11, and a first positioning pin 113 and a second positioning pin 114 are provided. At the same time, a supporting portion 121 is provided on the rear plate 12, and a first positioning hole 122 and a second positioning hole 123 are provided. During installation, the rear plate 12 can be firstly supported against the bottom side plate 112 in the left-right direction, and the first positioning pin 113 is inserted into the first positioning hole 122, so as to position the rear plate 12 in the front-back direction. Then, the rear plate 12 is moved downward, and the second positioning pin 114 enters the second positioning hole 123, so as to position the rear plate 12 in the left-right direction. Finally, the rear plate 12 is seated on the base 11 1, positioning is achieved in the up and down directions, thereby positioning is formed in three directions, and the locking holes 30 on the bottom bracket 11 and the rear plate 12 can be aligned; in this technical solution, the rear plate 12 is matched with the bottom bracket 11 in a suspended state, so the position of the first positioning pin 113 is set higher than the second positioning pin 114, at this time, the first positioning hole 122 on the rear plate 12 can be matched with the first positioning pin 113 on the bottom bracket 11, and in this process, the approximate position of the rear plate 12 in the left and right directions is also limited by the bottom side plate 112, and then the position in the left and right directions is accurately positioned by the cooperation of the second positioning pin 114 and the second positioning hole 123; therefore, the electrical component provided by the present invention can conveniently perform the positioning and matching of the rear plate 12 and the bottom bracket 11, facilitate the locking of the rear plate 12 and the bottom bracket 11, and effectively improve the work efficiency and reduce the labor cost.
