The multiple expansion boards 7 are vertically arranged and correspondingly plugged into the multiple expansion board slots on the main board 6. The pins of the expansion boards 7 are soldered to the pads on the main board 6 for electrical connection. The plugging method between the expansion boards 7 and the main board 6 facilitates subsequent disassembly, and expansion boards 7 with different functions can be replaced according to the needs of instrument industrial control. When replacement is required, the pads are desoldered and the expansion board 7 is removed.

[0027] The left and right sides of the rear housing 8 are provided with motherboard slots 82, and the edge of the motherboard 6 is provided with snap-fit ​​protrusions 62. The motherboard 6 with the expansion board installed is snap-fitted to the rear housing 8.

[0028] The front housing 1 and the rear housing 8 are snap-fitted together to form the instrument housing. (See also...) Figure 1 The front housing 1 has housing buckle grooves 11 on its left and right sides, and the rear housing 8 has buckle protrusions 81 on its left and right sides that cooperate with the housing buckle grooves.

[0029] Card slots 13 are provided on both the left and right sides of the front housing 1, and card-connecting protrusions 63 are provided on both the left and right sides of the display module of the motherboard 6.
