The back plate 120 includes a plate body 121, at least one protruding portion 122, and at least one pressing portion 123. The second surface 112 of the circuit board 110 is configured to abut against the board body 121 of the back plate 120. The protrusion 122 of the back plate 120 is connected to the plate 121 and is configured to be engaged with the through hole FH of the circuit board 110. The pressing portion 123 of the back plate 120 is connected to the plate body 121 and configured to elastically press against the first surface 111 of the circuit board 110.
The position of the circuit board 110 on the back plate 120 is fixed by the protrusion 122 of the back plate 120 being engaged with the through hole FH of the circuit board 110. Furthermore, by the pressing portion 123 of the back plate 120 elastically pressing against the first surface 111 of the circuit board 110, the second surface 112 of the circuit board 110 can be maintained to be abutted against the board body 121 of the back plate 120, so that the circuit board 110 cannot be separated from the back plate 120. That is, the protrusion 122 and the pressing portion 123 of the back plate 120 can effectively fix the circuit board 110 to the back plate 120, and the fixing manner does not involve the use of a locking element (such as a screw), so that convenience is brought to the user, and manufacturing cost and material cost can be saved.
Further, as shown in fig. 2 to 3, the pressing portion 123 of the back plate 120 includes a first portion 123a, a second portion 123b, and a third portion 123c. The first portion 123a of the pressing portion 123 is connected to the plate 121, and is bent relative to the plate 121, and the first portion 123a is configured to at least partially limit the edge 113a of the circuit board 110 (see fig. 2 for the circuit board 110), where the edge 113a of the circuit board 110 is connected to the first surface 111 and the second surface 112. In practice, the first portion 123a may contact the edge 113a or may be separated from the edge 113 a. The second portion 123b of the pressing portion 123 is connected to the first portion 123a, and the second portion 123b extends toward the plate 121 and is inclined relative to the plate 121. The third portion 123c of the pressing portion 123 is connected to the second portion 123b, and the third portion 123c extends away from the plate 121 and is inclined with respect to the plate 121, and is configured to press against the first surface 111 of the circuit board 110.
More specifically, as shown in fig. 2, the circuit board 110 has a thickness TK, and the first portion 123a of the pressing portion 123 has a height HT with respect to the board body 121. In the present embodiment, the height HT of the first portion 123a is greater than the thickness TK of the circuit board 110, so that the third portion 123c of the pressing portion 123 presses against the first surface 111 of the circuit board 110.
Please refer back to fig. 1. In the present embodiment, as shown in fig. 1, the board body 121 of the back plate 120 has a receiving area SC, and the receiving area SC is configured to receive the circuit board 110. Further, the accommodating range SC is divided into a first sub-range SC1 and a second sub-range SC2 connected to each other along the mounting direction DA, the pressing portion 123 and the protruding portion 122 are located in the first sub-range SC1, and the pressing portion 123 and the protruding portion 122 are arranged along the mounting direction DA. Specifically, the mounting direction DA is a direction in which the circuit board 110 is moved relative to the back plate 120 when the circuit board 110 is mounted on the back plate 120. For example, as shown in fig. 1, the mounting direction DA is a right-to-left direction, that is, the circuit board 110 moves from right to left relative to the back board 120, so that the protrusion 122 of the back board 120 engages with the through hole FH of the circuit board 110, and the pressing portion 123 of the back board 120 elastically presses against the first surface 111 of the circuit board 110.
On the other hand, in the present embodiment, as shown in fig. 1, the back plate 120 further includes a plurality of first limiting portions 124.

In practice, the fourth portion 124a may contact the edge 113b or may be separated from the edge 113 b. The fifth portion 124b of the first limiting portion 124 is connected to the fourth portion 124a, and is bent relative to the fourth portion 124a, and the fifth portion 124b is configured to abut against the first surface 111 of the circuit board 110.
The position of the circuit board 110 at the back plate 120 is fixed by at least partially restricting the edge 113b of the circuit board 110 by the fourth portion 124a of the first restricting portion 124. Furthermore, by the fifth portion 124b of the first limiting portion 124 abutting against the first surface 111 of the circuit board 110, the second surface 112 of the circuit board 110 can be maintained to abut against the board body 121 of the back plate 120, so that the circuit board 110 cannot be separated from the back plate 120.
Further, as shown in fig. 5, each of the first limiting portions 124 includes a first guiding portion 124c and a second guiding portion 124d. The first guide portion 124c connects the fourth portion 124a away from the pressing portion 123 in the mounting direction DA, and is inclined with respect to the fourth portion 124 a. The second guide portion 124d connects the fifth portion 124b away from the pressing portion 123 in the mounting direction DA, and is inclined with respect to the fifth portion 124 b. By tilting the first guiding portion 124c relative to the fourth portion 124a and tilting the second guiding portion 124d relative to the fifth portion 124b, the first guiding portion 124c and the second guiding portion 124d can provide guiding function for the circuit board 110 when the circuit board 110 moves along the mounting direction DA relative to the back plate 120 for mounting on the back plate 120.
On the other hand, in the present embodiment, as shown in fig. 1, the back plate 120 further includes a plurality of second limiting portions 125. The second limiting portion 125 is located in the first sub-range SC1 of the board 121, and the circuit board 110 is configured to be at least partially clamped between the second limiting portions 125.
Please refer to fig. 6-7. Fig. 6 is a cross-sectional view of fig. 1 along line C-C. Fig. 7 is a partially enlarged perspective view illustrating one of the second limiting portions 125 of fig. 1. In the present embodiment, as shown in fig. 6 to 7, each of the second stopper portions 125 includes a sixth portion 125a. The sixth portion 125a of the second limiting portion 125 is connected to the board 121 and bent with respect to the board 121, and the sixth portion 125a is configured to at least partially limit the edge 113b of the circuit board 110. In practice, sixth portion 125a may contact edge 113b, or may be separated from edge 113b.
The position of the circuit board 110 at the back plate 120 is fixed by at least partially restricting the edge 113b of the circuit board 110 by the sixth portion 125a of the second restricting portion 125.
Further, as shown in fig. 7, each of the second limiting portions 125 includes a third guiding portion 125b. The third guide portion 125b connects the sixth portion 125a near a corresponding one of the first limiting portions 124 in the mounting direction DA, and is inclined with respect to the sixth portion 125 a. By tilting the third guide portion 125b relative to the sixth portion 125a, the third guide portion 125b can provide a guiding function for the circuit board 110 when the circuit board 110 moves relative to the back plate 120 along the mounting direction DA to be mounted on the back plate 120.
Furthermore, as shown in fig. 6, the vertical projection of the second limiting portion 125 toward the board body 121 is far away from the first surface 111 of the circuit board 110, that is, the second limiting portion 125 is not overlapped on the first surface 111 of the circuit board 110, so that the difficulty in mounting the circuit board 110 on the back plate 120 can be effectively reduced.
In summary, the technical solution disclosed in the above embodiment of the present utility model has at least the following advantages: the convex part and the pressing part of the back plate can effectively fix the circuit board on the back plate, and the fixing mode does not involve the use of locking elements (such as screws), so that convenience can be brought to users, and the manufacturing cost and the material cost can be saved.
