[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is an electromagnetic isolation circuit board for a smart watch, comprising a circuit board 1, a main shielding cover 2 and a plurality of auxiliary shielding covers 4, wherein the circuit board 1 is provided with a plurality of sockets 8, and the bottom surface of the circuit board 1 is provided with a positioning groove 9 connected with the socket 8 at a position opposite to the socket 8, the main shielding cover 2 is covered on the circuit board 1, and a plug rod 5 is installed at a position opposite to the socket 8 on the bottom surface of the main shielding cover 2, the plug rod 5 is inserted into the inside of the socket 8, and a positioning plate 6 is movably installed through a pin shaft, and the positioning plate 6 rotates around the pin shaft and enters the positioning groove 9, and a plurality of auxiliary shielding covers 4 are assembled on the main shielding cover 2.

[0022] In this embodiment, grooves 3 are provided on the side surfaces of the main shielding cover 2, and both ends of the auxiliary shielding cover 4 are bent downward to form support portions, which are in contact with the top surface of the circuit board 1. An L-shaped plate 7 is installed on one side of the support portions, and the L-shaped plates 7 extend through the grooves 3 to the interior of the main shielding cover 2.

[0023] In this embodiment, the inner side surface of the vertical end of the L-shaped plate 7 is in contact with the inner side surface of the main shielding cover 2, the width of the horizontal end of the L-shaped plate 7 matches the width of the groove 3, and the bottom surface of the L-shaped plate 7 is in contact with the top surface of the circuit board 1, so that the inserted L-shaped plate can be stably pressed on the circuit board.

[0024] In this embodiment, the bottom surface of the positioning plate 6 is flush with the bottom surface of the circuit board 1 , so that after the circuit board contacts the bottom surface of the housing, the positioning plate can also be pressed synchronously.

[0025] In this embodiment, the insertion rod 5 and the positioning plate 6 are both made of metal materials, which increases the firmness and enables repeated use to ensure the service life.

[0026] In this embodiment, the cross-sections of the insertion rod 5 and the socket 8 are both arranged in a rectangular structure, which increases the stability after insertion and avoids the rotation of the insertion rod.

[0027] During installation, first straighten the positioning plate and pass it through the socket. After the main shielding cover is inserted into place, the positioning plate can be rotated so that the positioning plate enters the positioning groove, and the insertion rod is positioned in the socket.

[0028] Wherein, when the secondary shielding cover needs to be installed, the L-shaped plate on the secondary shielding cover can be inserted into the groove, so that the secondary shielding cover can be hooked on the main shielding cover, and after the main shielding cover abuts against the top surface of the circuit board, the L-shaped plate and the secondary shielding cover can be pressed;

[0029] After the circuit board is fixed in the housing, the bottom surface of the circuit board can be pressed on the bottom surface of the housing, and the positioning plate is also pressed on the bottom surface of the housing, so that the fixing of the circuit board can simultaneously fix the main shielding cover and the auxiliary shielding cover, which greatly increases safety efficiency;

[0030] When the circuit board is disassembled for repair or replacement, the positioning plate loses its limiting function, so that it can directly droop and can be directly moved out along the socket, so that the main shielding cover and the auxiliary shielding cover can be directly disassembled.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
