101 bottom；Upper locking member 3013 and the upper interference fit of screens groove 1011；Fluted 3011 are set on upper grafting body 3014.It is logical
Cross and the first fool proof block 301 is arranged to structure as implied above, the bottom of outer cover body 101 is stuck in using dop 3012, while
(because both are interference fit) is clamped in upper screens groove 1011 using upper locking member 3013, can so make the first fool proof block
301 are connected fastening while mistake proofing bit function is ensured with outer cover body 101.
In the utility model embodiment, as shown in figure 3, the second fool proof block 302 includes being sequentially connected with down from top to bottom
Locking member 3022 and underthrust junctor 3023；Lower locking member 3022 and the lower interference fit of screens groove 2021；Set on underthrust junctor 3023
It is equipped with projection 3021.It is arranged to structure as implied above by by the second fool proof block 302, is clamped on down using lower locking member 3022
In screens groove 2021 (because both are interference fit), the second fool proof block 302 can be so set to ensure the same of mistake proofing bit function
When be connected fastening with cover plate 202.
Preferably, dop 3012 includes cylinder and the head being arranged at the top of cylinder, the width of cylinder is less than upper screens
Groove 1011, the width of head is more than upper screens groove 1011.Also, cylinder with the longitudinal fluting that connects up and down is provided with head,
So as to dop 3012 is divided into two symmetrical sub- dops.Wherein, width refers to cylinder or head in radial direction most
Long length, upper screens groove 1011 is included for accommodating the column recesses of cylinder and recessed for accommodating the locking member of upper locking member 3013
Groove.It is in the insertion of the first fool proof block 301 during screens groove 1011, two heads of sub- dop are recessed to longitudinal direction by being arranged such
Groove direction is clutched, and makes two sub- dops sequentially through locking member groove and column recesses, automatic when head passes through column recesses
Flick, and be stuck in column recesses upper end, prevent the first fool proof block 301 in operation from coming off in the outer cover body 101, make the
One fool proof block 301 can securely be stuck in the bottom of outer cover body 101 by dop 3012.
In the utility model embodiment, upper locking member 3013 and lower locking member 3022 are both preferably positive six prismsby body, on
Screens groove 1011 and lower screens groove 2021 are the regular hexagon groove being adapted to positive six prismsby body phase, can either ensure that first prevents
The slow-witted fool proof block 302 of block 301 and second will not rotate in upper screens groove 1011 and lower screens groove 2021, can realize using again
In various docking modes of the shell of PLC system module, (the first fool proof block 301 or the second fool proof block 302 are in upper screens groove 1011
Or when in lower screens groove 2021, with groove 3011 or projection 3021 to direction it is different, main part 1 and bottom housing section 2
Docking mode it is also different).Wherein, the shape and upper screens groove 1011 of upper locking member 3013 and lower locking member 3022,
The quantity of lower screens groove 2021, the first fool proof block 301 and the second fool proof block 302 can be various, for example, upper locking member
3013 and lower locking member 3022 can be for square, positive eight prism etc., accordingly, upper screens groove 1011, lower screens groove 2021
It is square groove, positive eight prisms groove etc.；Screens groove 1011, lower screens groove 2021, the first fool proof block 301 and the second fool proof block
302 can be 2,3,4 etc..It is understood that upper screens groove 1011, lower screens groove 2021, the and of the first fool proof block 301
The quantity of the second fool proof block 302 is more, and the docking mode of main part 1 and bottom housing section 2 is more, for example, when upper card
Junctor 3013 and lower locking member 3022 are positive six prismsby body, and the quantity of the first fool proof block 301 and the second fool proof block 302 is 2
When, with groove 3011 or projection 3021 change to direction, the docking mode of main part 1 and bottom housing section 2 has 36 kinds,
Can guarantee that the unique match of the shell for PLC system module.
