[0043] The wire controller provided by the embodiment of the present invention includes a back cover 1 and a front cover 7, the back cover 1 includes an embedded portion 12, the embedded portion 12 is embedded in the wall, the front cover 7 is detachably connected to the back cover 1, the embedded portion 12 is embedded in the wall to prevent the back cover 1 from protruding from the wall surface, the front cover 7 is detachably connected to the back cover 1 to facilitate the staff to install, repair or replace the components in the back cover 1, the wire controller also includes a main control board 4, a liquid crystal assembly 5, a soft flat cable 8 and a mirror 9, the front cover 7 and the back cover 1 clamp the main control board 4 and the liquid crystal assembly 5, thereby preventing the main control board 4 and the liquid crystal assembly 5 from shaking and ensuring that the main control board 4 and the liquid crystal assembly 5 work stably, the soft flat cable 8 is arranged on the front cover 7, the mirror 9 and the front cover 7 clamp the soft flat cable 8 to prevent the soft flat cable 8 from falling off relative to the front cover 7 and avoiding damage to the soft flat cable 8.

[0044] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the flexible flat cable 8 includes a flexible flat cable body 81 and touch buttons 82. Compared with the method of installing a connector between the touch PCB board and the liquid crystal, since the flexible flat cable body 81 has the function of a connector, there is no need to install the connector separately, so the flexible flat cable body 81 can be set close to the liquid crystal component 5. The space for installing the connector is saved by replacing the touch PCB board with the flexible flat cable body 81. Since the distance between the flexible flat cable body 81 and the liquid crystal component 5 is small, the accommodating depth of the front cover 7 is reduced, that is, the thickness of the front cover 7 is reduced.

The limiting effect of the second groove 74 on the mirror 9 can prevent the mirror 9 and the front cover 7 from shaking relative to each other, and prevent the mirror 9 from being damaged or falling off. At the same time, the mirror 9 is accommodated in the second groove 74 to prevent the mirror 9 from protruding from the front cover 7, thereby reducing the thickness of the wire controller. In this embodiment, the mirror 9 is bonded to the front cover 7 with adhesive tape to further improve the stability of the connection between the soft flat cable 8 and the front cover 7.
