[0023] Reference example Figures 1 to 4 , an online switch with good protection effect, comprising a base 1, an upper cover 2 fixed on the base 1, and a switch body 3 fixed on the upper cover 2, the switch body 3 is provided with a first lead 31 and a second lead 32, the base 1 and the upper cover 2 are provided with a sealing ring 4, and the first lead 31 and the second lead 32 are wrapped, the upper cover 2 is provided with a clearance groove 21, both sides of the base 1 are provided with a convex block 11, and the sealing ring 4 is abutted, the convex block 11 is provided with a sealing strip 5, the convex block 11 is embedded in the clearance groove 21, so that the sealing strip 5 abuts the clearance groove 21, the upper cover 2 is provided with a plurality of clamping members 22, the base 1 is provided with a pressure block 12, and is inserted between the clamping members 22;

[0024] It is worth mentioning that the base 1 and the upper cover 2 are provided with a harness groove 6, and mounting holes 7 are provided at both ends of the base 1 and the upper cover 2. A wiring groove 8 is provided between the mounting holes 7. A stopper 9 is provided on the curved surface of the wiring groove 8, and abuts against the surface of the first lead wire 31 and the second lead wire 32. The harness groove 6 is convenient for placing a semi-annular sealing ring 4. Screws are placed in the mounting holes 7 to connect and fix the base 1 and the upper cover 2. The wiring groove 8 is used in conjunction with the stopper 9. The stopper 9 increases the anti-pulling ability of the first lead wire 31 and the second lead wire 32 to prevent the first lead wire 31 and the second lead wire 32 from being electrically connected to the switch body 3.

[0025] It is worth mentioning that retaining rings 41 are provided on both sides of the sealing ring 4 and abut against both sides of the wiring harness groove 6. The shape of the sealing ring 4 is set to be semi-annular. The retaining ring 41 prevents the sealing ring 4 from moving forward and backward following the first lead wire 31 and the second lead wire 32;

[0026] It is worth mentioning that the first lead wire 31 and the second lead wire 32 are provided with a limiting groove 33 and are arranged on the sealing ring 4. The two sides of the limiting groove 33 respectively abut against the side walls of the wiring harness groove 6. The first lead wire 31 is provided with a male plug 311, and the second lead wire 32 is provided with a female plug 321. The limiting groove 33 is used in conjunction with the sealing ring 4. The wiring harness groove 6 enables the first lead wire 31 and the second lead wire 32 to have an anti-pull function. The male plug 311 and the female plug 321 are convenient for connection with the quick plug in the electronic device.

[0027] It is worth mentioning that the base 1 is provided with a top plate 13, which is arranged on the side of the protrusion 11 and connected to the side of the wiring harness groove 6. The top plate 13 abuts against the inner wall of the upper cover 2. The pressure block 12 is provided with a reinforcing rib 14. The top plate 13 provides support for the clearance groove 21, so that the clearance groove 21 is in close contact with the sealing strip 5 to improve the sealing performance. The reinforcing rib 14 improves the connection strength between the pressure block 12 and the base 1;

[0028] It is worth mentioning that a plurality of support plates 23 are provided on both sides of the upper and lower sides centered on the middle of the upper cover 2, and the two ends of the clamping member 22 are connected and fixed to the support plates 23 by screws. The shape of the clamping member 22 is set to be arc-shaped, and the number of the clamping members 22 is set to eight. The support plates 23 provide strong support for the clamping member 22. When the upper cover 2 and the base 1 are closed, the pressure block 12 enters between the clamping members 22, so that the arc-shaped clamping member 22 moves toward its own center point, and then is in an energy storage state, and then releases the reaction force to clamp the pressure block 12, so that the middle section of the base 1 is tightly connected and fixed to the upper cover 2, thereby reducing the gap between the protrusion 11 and the yield groove 21, and preventing impurities such as water vapor and dust from entering the interior through the gap.

[0029] The above design scheme can enable the product to achieve the advantages of good sealing and stable operation.

[0030] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
