In an embodiment, the circuit board 20 is mounted on the inner bottom wall of the box body 10, and the inner bottom wall of the box body 10 is convexly disposed towards the direction of the circuit board 20, so that the inner bottom wall of the box body 10 can be better in contact with the circuit board 20, and the contact area between the circuit board 20 and the inner wall of the box body 10 is increased.

The circuit board 20 may be a power transformer board. The material adopted by the box body 10 can be metal material, so as to achieve better heat dissipation effect. For example, the case 10 may be made of aluminum, and the circuit board 20 may radiate heat by contacting the aluminum case 10 to improve heat radiation effect.

It should be noted that: the signal board 30 may receive the signal of the circuit board 20 by using an existing signal receiving method.

In a low temperature and high humidity environment, water droplets may condense on the face housing 12. In order to enable the water drops condensed on the surface shell 12 to automatically drop from the surface shell 12 due to the influence of gravity, the enclosing part 113 comprises a first side part 1131, a second side part 1132 and two connecting parts 1133, the first side part 1131 and the second side part 1132 are oppositely arranged, the two connecting parts 1133 are connected with the first side part 1131 and the second side part 1132, the height of the first side part 1131 is smaller than that of the second side part 1132, each connecting part 1133 is inclined downwards towards the horizontal plane towards the end face 1134 of the surface shell 12, the surface shell 12 is abutted against the inner top surface of the bottom shell 11 to form an abutting surface, and the abutting surface is inclined downwards towards the horizontal plane.

Since each of the connection portions 1133 is inclined downward toward the horizontal plane toward the end face 1134 of the face case 12, the face case 12 can be disposed obliquely with respect to the fixing portion 114. The top surface of the shell 12 abutting against the bottom shell 11 is an abutting surface, and the abutting surface is inclined downward toward a horizontal plane. Water droplets or snow may drip from the face housing 12.
