By making the projection of the bracket plate 31 on the circuit board 2 extend along the circumference of the circuit board 2, and the matching hole 21 extend along the circumference of the circuit board 2, the matching degree between the bracket plate 31 and the matching hole 21 is high, so that the bracket plate 31 is inserted into the matching hole 21, so that a continuous and uniform matching relationship along the circumference of the circuit board 2 is formed between the bracket plate 31 and the matching hole 21, which is conducive to improving the stability and reliability of the fixed relationship between the first bracket 3 and the circuit board 2.

[0050] refer to Figure 2-Figure 6According to some optional embodiments of the utility model, the matching hole 21 includes a first hole section 211, a second hole section 212 and a third hole section 213 sequentially arranged along the circumference of the circuit board 2, and an angle is formed between the first hole section 211 and the second hole section 212, and an angle is formed between the second hole section 212 and the third hole section 213.

Optionally, the support structure 33 located on the inner peripheral side of the bracket plate 31 is arranged adjacent to the bracket plate 31.

[0054] At least part of the support structure 33 located on the outer periphery of the bracket plate 31 is provided with a limit buckle 34, for example, part of the support structure 33 located on the outer periphery of the bracket plate 31 is provided with a limit buckle 34, or all of the support structure 33 located on the outer periphery of the bracket plate 31 is provided with a limit buckle 34.

[0055] The support structure 33 has a support surface 331 for supporting the circuit board 2. The limit buckle 34 and the support surface 331 are arranged opposite to each other and spaced apart in the first direction. The limit buckle 34 and the support surface 331 are located on opposite sides of the circuit board 2 along the first direction to limit the position of the circuit board 2 in the first direction. By making the limit buckle 34 and the support surface 331 opposite to each other and spaced apart in the first direction, and making the limit buckle 34 and the support surface 331 located on opposite sides of the circuit board 2 along the first direction to limit the position of the circuit board 2 in the first direction, the limit buckle 34 and the support surface 331 form a limiting effect on the circuit board 2 in the first direction, which can prevent the circuit board 2 from moving relative to the bracket plate 31 in the first direction, which is conducive to the stable fixing of the circuit board 2 to the first bracket 3, thereby facilitating the formation of a stable electrical connection relationship between the various parts in the adapter 100 and the circuit board 2.

The plug-in port 11 is formed on the first end cover 13, and the bracket plate 31 abuts against the inner side of the first end cover 13 along the first direction. By making the bracket plate 31 abut against the inner side where the plug-in port 11 is formed along the first direction, the bracket plate 31 is used to bear the external force, thereby protecting the circuit board 2 and preventing the circuit board 2 from being damaged due to a large external force. For example, in the process of covering the second end cover 14 on the open side of the housing body 12 opposite to the first end cover 13, it is possible to avoid damage to the circuit board 2 caused by the force applied to the second end cover 14.
