The metal mounting plate 21 and the back cover 22 are engaged by the hook 211 and the slot 223. Those skilled in the art will understand that existing wired controllers mainly include a back cover 22 and a front panel 23, with the back cover 22 directly connected to the 86 box 11. In contrast, the wired controller body 2 of this structure is fixed to the 86 box 11 embedded in the wall 1 via the metal mounting plate 21. The metal mounting plate 21 is less prone to deformation, increasing structural strength. Preferably, the metal mounting plate 21 has a wire harness through-hole 214 in the middle for easy cable insertion. Meanwhile, connecting holes 32 are provided on both sides of the wire harness through hole 214. The positions of the connecting holes 32 correspond to the holes on the metal plates on both sides of the 86 box 11. By screwing in screws, the metal mounting plate 21 can be connected to the 86 box 11. At the same time, this structure has a hook 211 on the side wall of the metal mounting plate 21 above the wire harness through hole 214, and a slot 223 on the back side wall of the rear cover 22. The metal mounting plate 21 and the rear cover 22 are fixed by engaging with the hook 211 and the slot 223.

[0024] Preferably, in the above structure, a ring of recessed reinforcing ribs 213 is provided on the outside of the wire harness through-hole 214 of the metal mounting plate 21. Those skilled in the art will understand that, in order to increase the structural strength of the metal mounting plate 21, this structure preferably provides a ring of recessed reinforcing ribs 213 on the outside of the wire harness through-hole 214 of the metal mounting plate 21; in practice, a groove can be pressed under the wire harness through-hole 214.

[0025] Preferably, in the above structure, the lower end of the slot 223 is connected to a guide groove 222, and the guide groove 222 is larger than the slot 223. Those skilled in the art will understand that, to facilitate the quick insertion of the hook 211, this structure actually has a guide groove 222 connected to the lower end of the slot 223, and the guide groove 222 is larger than the slot 223. In practice, the hook 211 can be first inserted into the guide groove 222 for initial positioning, and then the rear cover 22 can be moved upwards to allow the hook 211 to slide into the slot 223 for fixation.

[0026] Preferably, the guide groove 222 in the above structure is trapezoidal in shape, and its upper bottom end is connected to the lower end of the slot 223. Those skilled in the art will understand that the structure of the guide groove 222 is further preferred; specifically, the guide groove 222 is trapezoidal in shape, and its upper bottom end is connected to the lower end of the slot 223. With this structure, because the guide groove 222 is large, the hook 211 can easily be inserted into the guide groove 222. Since the guide groove 222 is trapezoidal, both sides are upwardly tapering inclined surfaces. In practice, the guide groove 222 can preferably be an isosceles trapezoid, which, under the action of the inclined surface, enters the slot 223 to achieve snap-fit ​​fixation.

[0027] Preferably, a flange wall 215 is provided on the outer side of the wire harness through hole 214 in the above structure. Those skilled in the art will understand that, in order to limit the left-right swaying of the lower part of the rear cover 22, this structure provides a flange wall 215 on the outer side of the wire harness through hole 214. Since a square through hole 221 for the wire harness to pass through is provided in the middle of the rear cover 22, the width of the flange wall 215 should be adapted to the width of the through hole 221, so that the rear cover 22 can be fitted over the flange wall 215 to achieve left-right positioning.

[0028] Preferably, the flange wall 215 in the above structure is a U-shaped structure and is disposed along the lower outer side of the wire harness through hole 214.

Those skilled in the art will understand that, to facilitate the connection between the lower part of the rear cover 22 and the metal mounting plate, this structure further provides a locking groove 216 at the upper end of the flange wall 215 opening, and locking posts 224 on the two side walls of the through hole 221 in the middle of the rear cover 22. The locking posts 224 are arranged along the width direction of the through hole 221, so that the locking posts 224 are engaged in the locking groove 216, and at this time, the hook 211 is engaged with the groove 223, thereby achieving the connection and fixation of the upper and lower parts of the rear cover 22 to the metal mounting plate 21 respectively. When removing, the rear cover 22 is simply disengaged from the hook 211 and the locking groove 216.

[0030] Preferably, the upper part of the locking groove 216 in the above structure is an inverted trapezoidal structure that is larger at the top and smaller at the bottom. Those skilled in the art will understand that since the locking groove 216 mainly engages with the locking post 224, the locking groove 216 is actually a U-shaped structure with an open top. To facilitate the smooth insertion of the locking post 224 into the lower part of the locking groove 216 during engagement, this structure preferably features an inverted trapezoidal structure with a larger top and smaller bottom for the upper part of the locking groove 216, with the upper inclined surface guiding the insertion.

[0031] Preferably, the mounting hole 212 in the above structure is a countersunk hole structure. Those skilled in the art will understand that, to avoid interference and conceal the screws, the connecting hole 32 is preferably a countersunk hole structure, so that the outer end of the screw used to connect the metal mounting plate 21 and the 86 box 11 is placed inside the countersunk hole after tightening.
