[0020] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] See appendix Figure 1-4 As shown, the double-gasket sealed connector of Embodiment 1 includes a lower housing 1; an upper housing 2 adapted to the lower housing 1, the upper housing 2 being able to seal the lower housing 1; the electronic components inside the connector can be placed inside the lower housing 1 and then sealed by the upper housing 2.

[0022] The lower housing 1 has an upwardly extending inner spacer ring 11 inside, and the upper housing 2 has a downwardly extending outer spacer ring 21 inside. After the upper housing 2 closes the lower housing 1, the inner spacer ring 11 will be in close contact with the outer spacer ring 21. The lower housing 1 has a first protruding ring 12 inside that can fit with the outer spacer ring 21. The upper housing 2 has a second protruding ring 22 inside that is close to the inner spacer ring 11. A first sealing gasket 13 is provided between the first protruding ring 12 and the outer spacer ring 21, and a second sealing gasket 23 is provided between the second protruding ring 22 and the inner spacer ring 11.

[0023] The inner spacer ring 11 and the outer spacer ring 21 are arranged in a tightly interlocking manner to form a sealing structure. When the upper housing 2 and the lower housing 1 are engaged, the outer spacer ring 21 will abut against the first sealing gasket 13, and the inner spacer ring 11 will abut against the second sealing gasket 23, thereby strengthening the sealing structure, increasing the sealing performance, preventing rainwater from flowing into the interior of the lower housing 1, thus improving the service life of the connector, making it unaffected by rain and snow, and improving its practicality.

[0024] Furthermore, a placement groove is formed between the first convex ring 12 and the outer spacer ring 21, the size of which is adapted to the size of the first sealing gasket 13 and the outer spacer ring 21.

[0025] The placement groove is used to place the first sealing gasket 13, so that the first sealing gasket 13 can be inserted into the placement groove. When the outer spacer ring 21 abuts against the first sealing gasket 13, a labyrinth-type sealing structure can be formed, further increasing the sealing ability.

[0026] Furthermore, a mounting groove is formed between the second convex ring 22 and the inner spacer ring 11, which is adapted to the size of the second sealing gasket 23.

[0027] The second sealing gasket 23 can be inserted into the mounting groove and can be abutted by the inner spacer ring 11, thereby increasing the sealing between the inner spacer ring 11 and the upper housing 2, and forming an inner labyrinth sealing structure to prevent water from entering the interior.

[0028] Furthermore, the second protruding ring 22 can be used to mount the circuit board with screws.

[0029] Screw holes can be provided on the second protruding ring 22 so that the circuit board can be fixed through the screw holes.
