The connecting piece 10 includes a piece body 11, a first supporting portion 12 and a second supporting portion 13; wherein the first supporting portion 12 and the second supporting portion 13 are both connected to the piece body 11 and extend toward both sides of the piece body 11 respectively. The piece body 11 is used to be connected to the circuit board 20, and the first supporting portion 12 and the second supporting portion 13 are both used to abut against the circuit board 20.

[0044] During operation, the connecting piece 10 can be supported against the circuit board 20 by the first supporting portion 12 and the second supporting portion 13, thereby supporting both sides of the piece body 11, preventing the piece body 11 from being tilted relative to the circuit board 20, improving the stability of the electrical connection, and reducing the failure rate of the intelligent switch 1000.

[0045] It is worth noting that during the installation process, the bottom end of the sheet body 11 will be plugged into the circuit board 20, and the circuit board 20 is provided with a socket that matches the sheet body 11. The bottom sides of the first support portion 12 and the second support portion 13 will abut against the circuit board 20, which not only supports the sheet body 11, but also plays a limiting role to prevent the bottom end of the sheet body 11 from being inserted too deep into the socket. In addition, the bottom end of the sheet body 11 can also be provided with a protruding structure, that is, the bottom end is in a step shape as a whole, which can also play a limiting role through the step abutment.

[0046] In this embodiment, the number of the first support portion 12 and the second support portion 13 are both one; in other embodiments of the utility model, the number of the first support portion 12 and the second support portion 13 can also be two, three, five, etc., and there is no limitation on the specific number.

[0047] refer to Figure 1 and Figure 2 The sheet body 11 has a first side surface 111, a first end surface 113, a second side surface 112 and a second end surface 114 which are arranged in sequence. One end of the first support portion 12 is connected to the first end surface 113, and the other end of the first support portion 12 is away from the second side surface 112 relative to the first side surface 111. One end of the second support portion 13 is connected to the second end surface 114, and the other end of the second support portion 13 is away from the first side surface 111 relative to the second side surface 112.

[0048] In the above technical solution, the first side surface 111 and the second side surface 112 are arranged opposite to each other, and the first end surface 113 and the second end surface 114 are arranged opposite to each other, so that the first support portion 12 and the second support portion 13 are also arranged symmetrically about the center of the sheet body 11, and the sheet body 11 not only does not tilt in the arrangement direction of the first side surface 111 and the second side surface 112, but also can prevent the sheet body 11 from tilting in the arrangement direction of the first end surface 113 and the second end surface 114.

[0049] In this embodiment, the first support portion 12 and the second support portion 13 are both in a straight line structure; of course, in other embodiments of the present invention, the first support portion 12 and the second support portion 13 may also be in a curved line structure.

[0050] refer to Figure 3 In order for the first support portion 12 and the second support portion 13 to provide better supporting force, an angle α can be formed between the first support portion 12 and the first side surface 111, wherein 10°≤α≤90°, and an angle β can be formed between the second support portion 13 and the second side surface 112, wherein 10°≤β≤90°.

[0051] In this embodiment, α=90° and β=90°; of course, in other embodiments of the present invention, the sizes of α and β can also be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc. There is no limitation on their specific sizes, and their angles can be the same or different.

[0052] refer to Figure 1-Figure 3 Because the wire 30 will contact the sheet body 11 during the assembly of the circuit board assembly 100 , in order to improve the fixing effect on the wire 30 , a convex bump 115 may be formed on the second side surface 112 of the sheet body 11 , and the convex bump 115 is used to resist the wire 30 .

[0053] In this embodiment, the cross-section of the convex hump 115 is circular, so that there are no sharp edges and corners that may cause damage to the wire 30 during the process of supporting the wire 30; of course, in other embodiments of the utility model, under the premise of ensuring the safety of the wire 30, the cross-section of the convex hump 115 can also be rectangular, triangular, prismatic, elliptical or other shapes, and the specific shape of the convex hump 115 is not limited.

[0054] Furthermore, in order to reduce the process cost, the convex bump 115 can be formed by stamping the sheet body 11 along the direction from the first side surface 111 to the second side surface 112. During the stamping process, a groove 116 is formed on the second side surface 112, and the groove 116 is arranged corresponding to the convex bump 115 and is used to abut the fastener 50, so that the end portion of the fastener 50 is accommodated in the groove 116, thereby improving the relative position stability of the fastener 50 and the sheet body 11.

[0055] refer to Figure 1-Figure 3 In order to improve the convenience of inserting the wire 30 during the assembly process of the circuit board assembly 100, the connecting piece 10 can also include a guide portion 14, which is inclined relative to the sheet body 11, one end of the guide portion 14 is connected to the top of the sheet body 11, and the other end of the guide portion 14 extends in a direction away from the convex hump 115.

[0056] During the process of inserting the wire 30 , the wire 30 may first contact the guide portion 14 , and the guide portion 14 may guide the wire 30 so as to move the guide to the side that can contact the convex bump 115 , thereby improving the insertion efficiency of the wire 30 .

[0057] refer to Figure 4-Figure 6 The embodiment of the utility model also provides a circuit board assembly 100 for an intelligent switch 1000, the circuit board assembly 100 includes a circuit board 20, a wire 30, a terminal 40, a fastener 50 and a connecting sheet 10; the sheet body 11 is plugged into the circuit board 20, the circuit board 20 is simultaneously supported on the bottom surfaces of the first support portion 12 and the second support portion 13, the terminal 40 is sleeved on the sheet body 11 and arranged on the top surfaces of the first support portion 12 and the second support portion 13, the fastener 50 is supported on one side of the sheet body 11 and spirally matched with the terminal 40, the wire 30 is accommodated in the terminal 40 and is located on the other side of the sheet body 11.

[0058] Specifically, the fastener 50 may be a bolt, and a fastening hole 42 is formed on the terminal 40 . An inner wall of the fastening hole 42 is formed with an internal thread so that the fastening hole 42 and the fastener 50 are threadedly connected.

[0059] When it is necessary to compress the wire 30, the fastener 50 can be screwed, and the terminal 40 can be driven to move axially along the fastener 50 through the threaded connection between the fastener 50 and the fastening hole 42. Because the connecting piece 10 is fixed relative to the circuit board 20, the space accommodating the wire 30 will be compressed during the movement of the terminal 40, thereby causing the guide to be pressed between the terminal 40 and the connecting piece 10.

[0060] It is worth noting that one circuit board 20 can correspond to multiple groups of terminals 40, fasteners 50 and connecting pieces 10, the terminals 40, fasteners 50 and connecting pieces 10 are one-to-one corresponding, and one terminal 40 can accommodate multiple groups of wires 30 at the same time.

[0061] refer to Figure 6 In order to better compress the wire 30 , a limiting surface 41 is formed on the terminal 40 , and a convex bump 115 is formed on the sheet body 11 . The two ends of the limiting surface 41 are closer to the convex bump 115 relative to the middle, and the wire 30 is held between the convex bump 115 and the limiting surface 41 .

[0062] Specifically, the limiting surface 41 is located on the inner wall of the end of the terminal 40 and is arranged opposite to the wall surface on which the fastening hole 42 is provided, so that the end of the terminal 40 formed with the limiting surface 41 is approximately a U-shaped structure, and the two ends of the U-shape extend toward one side away from each other, so that the wire 30 can be supported against the bottom and side surfaces of the U-shaped structure.

[0064] The intelligent switch 1000 and the circuit board assembly 100 both include a connecting piece 10 , which has all the functions of the connecting piece 10 .

[0065] In summary, the connecting sheet 10, the circuit board assembly 100 and the intelligent switch 1000 provided by the embodiments of the present invention have at least the following advantages:
