the female connector 2 comprises a female inner frame 21, a sealing ring 22, a female conductive terminal 23, a female terminal wire 24, a sleeve cap 25 and a female connector seat 26; the female inner frame 21 comprises a sealing ring setting part 211, a sleeve cap positioning part 212, a female inner frame boss 213 and a female inner frame tail part 214; the sealing ring setting part 211 is sleeved into the sleeved hole 1114 of the sleeved ring 111 of the male inner frame 11; the seal ring 22 is arranged in a groove 2111 of the seal ring arrangement part 211; one end of the female conductive terminal 23 is inserted into a female terminal hole 2112 of the seal ring setting part 211 from the female inner frame tail 214, the female inner frame boss 213 and the sleeve cap positioning part 212 in sequence, and the other end is connected with the female terminal wire 24; after the sleeve cap 25 is sleeved from the seal ring setting part 211, the inner end of the sleeve cap is positioned by a clamping groove 2121 on the outer wall of the sleeve cap positioning part 212 so as to prevent the sleeve cap from axially falling out of the seal ring setting part 211; the sleeve cap 25 can rotate forward and backward along the clamping groove 2121, and the rotation amplitude of the sleeve cap is limited by the angle rotation positioning structure 3; an elastic hook 251 is provided on the inner wall of the socket cap 25, and is elastically caught in the hook locking groove 1112 after being slid in along the guide insertion groove 1111 of the socket ring 111; when the sleeve cap 25 rotates, the sleeve cap 25 can slide out of the hook locking groove 1112 and then slide into the hook sliding groove 1113, and at this time, the sleeve cap 25 can be pulled out of the sealing ring setting part 211, so that the purposes of unlocking the male connector and the female connector and pulling out the male connector and the female connector are achieved; the female connector housing 26 is injection molded over the female inner frame tail 214 and the length of female end wire 24 adjacent the female inner frame tail 214. A space for the sleeve ring 111 of the male inner frame 11 to sleeve is formed between the sleeve cap 25 and the seal ring setting part 211 of the female inner frame 21; the waterproof connector may be two-core, or multi-core (e.g., three-core, four-core, five-core, etc.), in this embodiment, a five-core waterproof connector. In order to facilitate guiding and prevent reverse insertion, a mating mounting guide post 1115 and a mating mounting guide slot 2113 are provided in the axial direction of the inner wall of the collar 111 and the axial direction of the outer wall of the seal ring setting portion 211.

When the male and female connectors 1, 2 are to be sleeved together, the seal ring setting portion 211 is aligned with the sleeve ring 111 and is sleeved inside the ring, and at this time, the sleeve cap 25 is also sleeved outside the sleeve ring 111 in a sliding manner (even if the elastic hook 251 of the sleeve cap is slightly deviated from the hook guiding insertion groove 1111, the elastic hook is guided by the front end of the hook guiding insertion groove 1111, so that the sleeve cap is smoothly sleeved inside); with the further inward sleeving, under the action of the locking part 114, the elastic hook 251 axially slides out with slight elastic deformation from the inner end of the hook guiding insertion groove 1111 and rapidly slides into the hook locking groove 1112, so that the sleeving of the male and female connectors is completed, and in this case, the male and female connectors 1 and 2 cannot be pulled out directly. When the male and female connectors 1 and 2 are to be pulled out, the socket cap 25 is slightly rotated to make the elastic hooks 251 on the inner wall slide out of the hook locking grooves 1112 in the radial direction and slide into the hook sliding grooves 1113 rapidly, so that the male and female connectors can be pulled out.

As can be seen from the above, when the male and female inner frames 11 and 21 are axially sleeved together, the sleeve cap 25 is synchronously sleeved on the outer wall of the front end of the male inner frame 11, and the elastic hooks 251 on the inner wall of the sleeve cap 25 are hooked in the hook locking grooves 1112 of the male inner frame 11 to achieve sleeve locking of the male and female connectors, which is faster and easier than the nut type waterproof connector which can be sealed and locked only by rotating for a plurality of circles at the present stage when the waterproof connector is installed in a butt joint mode; meanwhile, since the socket cap 25 is sleeved on the female inner frame 21 and can slightly rotate a certain angle along the female inner frame 21, when the socket cap 25 is slightly rotated, the elastic hooks 251 on the inner wall of the socket cap 25 can radially slide out of the hook locking grooves 1112 and quickly slide into the hook sliding grooves 1113, the male and female connectors 1 and 2 can be pulled out, and under the structure, the socket cap 25 does not use a spring to realize the locking of the waterproof connector and the reset of the socket cap after rotation, compared with the quick-plug connector which can pull out the male and female connectors by pulling out the socket cap outwards while overcoming the spring force, the quick-plug connector has the advantages of simple and easy operation, and simpler structure and assembly production, and more reasonable and simple structure and more convenient operation.

In this embodiment, as shown in fig. 3, 4 and 5, the locking portion 114 is provided with a positive guide slope 1141 on the side facing the hook guide insertion groove 1111, and a vertical surface 1142 on the side facing the hook locking groove 1112, the former facilitates the sliding of the elastic hook 251 into the hook locking groove 1112 after sliding out of the hook guide insertion groove 1111, and the latter prevents the elastic hook 251 from being pulled out of the hook locking groove 1112 in the axial direction.

In this embodiment, as shown in fig. 3, 4 and 5, the hook locking groove 1112 is provided with a side guide slope 11121 on the side facing the hook sliding-out groove 1113 so as to more quickly slide the elastic hook 251 out of the side of the hook locking groove 1112 and into the hook sliding-out groove 1113 when the elastic hook is released. In this embodiment, the two hook sliding grooves 1113 are located at two sides of the axis (i.e. the axis formed by the hook guiding insertion groove and the hook locking groove), so that the user can rotate the socket cap 25 clockwise or counterclockwise according to the usage habit to unlock the elastic hook 251, thereby further facilitating the daily assembly and disassembly; it can be seen that since there are two hook slide out grooves 1113, there are two side guide slopes 11121 of the hook locking groove 1112, which are respectively abutted against each of the hook slide out grooves 1113.

In this embodiment, as shown in fig. 5, 6 and 8, the angular rotation positioning structure 3 includes an arc-shaped notch 31 provided on the socket cap positioning portion 212 and an angle limiting boss 32 provided on the inner wall of the socket cap 25; the angle limiting boss 32 is disposed in the arc-shaped notch 31 and limits the maximum angle of rotation of the socket cap 25 by the side walls at both sides of the arc-shaped notch 31. Of course, the angular rotation positioning structure 3 may be other structures.

The front end of the hook guide insertion groove 1111 is flared so that it is Y-shaped in a top view, so that even if the socket cap is in a relatively free state (when the elastic hooks 251 are not aligned with the hook locking grooves 1112) during socket connection, the socket cap 25 can be automatically rotated and aligned under the guide of the hook guide insertion groove 1111 to align the elastic hooks 251 on the inner wall thereof with the hook locking grooves 1112 during insertion.

At least two inner clamping tables 252 which can be clamped in the clamping grooves 2121 of the sleeve cap positioning part 212 are arranged on the inner peripheral wall of the inner end of the sleeve cap 25, when the sleeve cap 25 is sleeved inwards from the sealing ring setting part 211, the inner clamping tables 252 slightly spread outwards under the action of the front end of the sleeve cap positioning part 212 and then slide into the clamping grooves 2121 of the sleeve cap positioning part 212, so that the sleeve cap 25 is installed. In this embodiment, as shown in fig. 8, there are 8 inner clamping stages 252 circumferentially distributed on the inner peripheral wall of the socket cap 25.

To achieve a better sealing effect and to eliminate the need for a ring-seal mounting step, the ring seal 22 is typically injection molded into the groove 2111 of the ring seal arrangement 211.

In this embodiment, there are two elastic hooks 251 on the inner wall of the sleeve 25, and the elastic hooks are distributed at 180 degrees; accordingly, the male inner frame 11 is also composed of two sets of the hook guide insertion groove 1111, the hook locking groove 1112, and the hook sliding-out groove 1113.
