Referring to FIGS. 1-2, a waterproof connector 100 includes a cover 10 and a waterproof connector component 20 cooperated with the cover 10.

The cover 10 has a mounting hole 11 used for connecting to the waterproof connector component 20. The mounting hole 11 protruded inwardly to form a fixed block 110.

Also referring to FIGS. 3-4, the waterproof connector component 20 includes a body 21, a gasket 22 around an outer surface of the body 21, and a fastening piece 23 mounted on the outer surface of the body 21.

The body 21 is consisted of multiple cylinders which have different diameters and a common axis. The outer surface of the body 21 protruded outwardly to form a first ring 201, a second ring 202 and a third ring 203 spaced form the second ring 202. The second ring 202 locates between the first ring 201 and the third ring 203. A diameter of the first ring 201, the second ring 202 and the third ring 203 are greater than that of the body 21. The diameter of the first ring 201 is greater than that of the second ring 202. The diameter of the second ring 202 is equal to that of the third ring 203.

The first ring 201 and the second ring 202 commonly define a first groove 212 for placing the gasket 22 therein. The second ring 202 and the third ring 203 commonly define a second groove 213 for placing the fastening piece 23 therein. A diameter of a cylinder correspondingly to the first groove 212 is greater than a diameter of a cylinder correspondingly to the second groove 213.

An end of the body 21 closed to the first ring 201 forms a connecting portion 204. An outer surface of the connecting portion 204 forms a locating slot 205. Thus, the body 21 is coupled with a cable terminal through the connecting portion 204. Another end of the body 21 closed to the third ring 203 forms a positioning groove 206 cooperated with the fixed block 110 therein. The positioning groove 206 extends through the third ring 203 and the second groove 213.

The gasket 22 has ring shaped and has uniform inner diameter. The gasket 22 includes a first portion 221, a second portion 222 closed to the first portion 221, and the third portion 223 closed to the second portion 222. An outer diameter of the first portion 221 is greater than that of the second portion 222. An outer diameter of the third portion 223 gradually decreases away from the second portion 222. While the gasket 22 is positioned on the first groove 212, the first portion 221 of the gasket 22 contacted with the first ring 201. The outer diameter of the first portion 221 is either equal to or less than the outer diameter of the first ring 201. A least outer diameter of the third portion 223 is either equal to or less than the outer diameter of the second ring 202.

The fastening piece 23 includes a first extending portion 231, a second extending portion 232 opposite to the first extending portion 231, and a connection portion 233 connecting the first extending portion 231 and the second extending portion 232. The first extending portion 231, the second extending portion 232 and the connection portion 233 commonly define an open 230. An inner surface of the first extending portion 231 is parallel with an inner surface of the second extending portion 232. An inner surface of the connection portion 233 is a circular arc face.

While the waterproof connector 100 is assembled, the body 21 inserts the mounting hole 11 of the cover 10, the fixed block 110 is positioned on the positioning groove 206 to prevent the waterproof connector component 20 rotating relative to the cover 10. The first ring 201 contacts with an outer surface of the cover 10. The gasket 22 is positioned on the first groove 212 to prevent form water into the cover 10. The fastening piece 23 is mounted on the second groove 213. Thus, the first ring 201 and the fastening piece 23 commonly limits the waterproof connector component 20 to move relative to the cover 10 along an axis of the cover 10. Further, the fastening piece 23 can increase reinforce tightness between the waterproof connector component 20 and the cover 10.

Referring to FIGS. 5-7, an assembly method of the waterproof connector 100 includes the follow steps:

Referring to FIG. 5, providing a cover 10 and a body 21, a gasket 22, and a fastening piece 23, positing the gasket 22 on the body 21.

The cover 10 has a mounting hole 11. The mounting hole 11 protruded inwardly form a fixed block 110. An outer surface of the body 21 protruded outwardly to form a first ring 201, a second ring 202 and the third ring 203. The second ring 203 locates between the first ring 201 and the third ring 203. A diameter of the first ring 201, the second ring 202 and the third ring 203 is greater than that of the body 21. The diameter of the first ring 201 is greater than that of the second ring 202 and the third ring 203. The diameter of the second ring 202 is equal to that of the third ring 203. The first ring 201 and the second ring 202 commonly define a first groove 212 for placing the gasket 22 therein. The second ring 202 and the third ring 203 commonly define a second groove 213 for placing the fastening piece 23 therein. Further, an end of the body 21 closed to the third ring 203 forms a positioning groove 206 for cooperated with the fixed block 110 therein. The positioning groove 206 extends through the third ring 203 and the second groove 213.

Referring to FIG. 6, inserting the body 21 into the mounting hole 11 of the cover 10.

While inserting, the fixed block 110 is need to aim at the positioning groove 206. The first ring 201 contacts with an outer surface of the cover 10.

Referring to FIG. 7, inserting the fastening piece 23 into the second groove 213 to reinforce tightness between the waterproof connector component 20 and the cover 10.

Thus, the first ring 201 and the fastening piece 23 commonly prevent the waterproof connector component 20 rotating around an axis of the cover 10.
