The first extending part 11b and the second extending part 11c can rotate relative to the base part 11a, respectively.

The printed circuit board 11 may include a connection pin 118 and an electrical component 119. The electric components 119 can be electrically connected to each other. The connection pin 118 may electrically connect the electric component 119 to the external module. For example, the connection pin 118 may be inserted into the external module. For example, the connection pin 118 may be provided on the base part 11a, and the electric part 119 may be provided on the first extending part 11b and the second extending part 11c. The printed circuit board 11 may be deformed to have a substantially U shape so that the electric component 119 is located inside the first extending part 11b and the second extending part 11c. Due to such a shape, the printed circuit board 11 can be accommodated compactly in the housing 90.

The printed circuit board 11 includes a first mounting hole 112, a second mounting hole 113, a first mounting groove 114, a second mounting groove 115, a first mounting guide groove 116, And may include a mounting guide groove 117.

The first mounting groove 114 may receive at least a portion of the left coupler projection 124. The second mounting groove 115 can receive at least a part of the right coupler projection 125. The first mounting guide groove 116 and the second mounting guide groove 117 are provided in the front of the first mounting hole 112 and the second mounting hole 113 respectively so that the left coupler arm 122 and the right coupler arm 123 can be guided. The printed circuit board 11 can secure a large area for accommodating the electric component 119 by providing a minimum number of mounting holes (for example, two mounting holes for each coupler 12).

The coupler 12 can prevent the first extended portion 11b and the second extended portion 11c of the printed circuit board 11 from approaching each other. The coupler 12 may be disposed between the inner surface of the first extending part 11b and the inner surface of the second extending part 11c. Here, the inner surface of the first extending part 11b means the surface facing the second extending part 11c. The outer surface of the first extended portion 11b faces the inner wall of the housing 90. Likewise, the inner surface of the second extending part 11c means the surface facing the first extending part 11c. The outer surface of the second extending part 11c faces another inner wall of the housing 90. The coupler 12 can maintain the minimum distance of the first extending part 11b and the second extending part 11c. For example, two couplers 12 may be provided.
