The first wire hole 120 is connected to the accommodating space 110 and the mounting groove 130 respectively. The sealing member 200 is disposed in the mounting groove 130 and is formed with a second wire hole 210. The second wire hole 210 is connected to the mounting groove 130. The tail cover 300 is installed on the housing 100 and is used to press the seal 200 into the installation groove 130, and the tail cover 300 is formed with a third wire hole 310, which is connected to the second wire hole 210; the cable 400 is passed through the first wire hole 120, the second wire hole 210 and the third wire hole 310, wherein the cross-sectional area of ​​the installation groove 130 gradually decreases along the direction of the installation groove 130 toward the first wire hole 120. Compared with the prior art, the sealing structure 10 of the electronic component provided in the present application has a simple structure, low production cost, good installation convenience and high waterproof performance; and because the cross-sectional area of ​​the installation groove 130 gradually decreases along the direction of the installation groove 130 toward the first wire hole 120, the waterproof performance of the sealing structure 10 of the electronic component can be further improved.

[0024] Optionally, the shell 100 includes a main body 140 and an extension portion 150, the main body 140 is formed with a accommodating space 110 and a first wire hole 120, the extension portion 150 is formed by extending from the side wall of the main body 140 in a direction away from the accommodating space 110, and the extension portion 150 is formed with a mounting groove 130, and the tail cover 300 is installed on the extension portion 150.
