[0019] like Figures 1-7 As shown, this utility model provides a quick-plug waterproof electrical connector, including: a plug housing 10, wherein a plurality of socket holes 11 are provided in the plug housing 10, and a locking pin 12 is fixedly provided in each socket hole 11; a mounting groove 13 is also provided on the outer side of the middle part of the plug housing 10, the mounting groove 13 is spaced apart at a predetermined position, at least one plug notch 14 is provided on one side of the mounting groove 13 and at least one unlocking notch 15 is provided at a predetermined position; a plug protrusion 16 is also provided in the mounting groove 13 at a position corresponding to the plug notch 14; the plug housing... A connecting ring 17 is also sleeved on the outer side of one end of the body 10. At least one limiting boss 18 is provided on the inner wall of one end of the connecting ring 17. The limiting boss 18 is adapted to the plug notch 14. The inner wall of the connecting ring 17 is also provided with several stop ribs 19. The limiting boss 18 is located in the mounting groove 13 through the plug notch 14, and the limiting boss 18 and the stop ribs 19 cooperate with the side wall of the mounting groove 13 to restrict the connecting ring 17 from disengaging. The mounting groove 13 is provided with a mating sealing ring 20 in the side wall of one end of the connecting ring 17. Specifically, the plug housing 10 is a female connector, and several sockets 11 are formed inside the plug housing 10. Each socket 11 is fixedly connected to a wire-locking pin 12 by a screw. One end of the wire-locking pin 12 is used to connect the cable, and the other end is used to connect to the contact terminal of the male connector. A mounting groove 13 is also provided on the outer side of the middle part of the plug housing 10. The mounting groove 13 is formed by two raised and spaced steps. The mounting groove 13 is separated into two or three segments at a predetermined position, so that the mounting groove 13 is in a non-connected state. At least one plug notch 14 is formed on one side of the step of the mounting groove 13. At least one or two plug notches 14 are located at the separated positions of the mounting groove 13, depending on the number of segments of the mounting groove 13. At the same time, in the mounting groove 13 A plug protrusion 16 is provided adjacent to the plug notch 14, with one plug notch 14 corresponding to one plug protrusion 16. The plug protrusion 16 is offset from the plug notch 14. A connecting ring 17 is connected to the end of the plug notch 14, with the mounting groove 13 as the boundary. The connecting ring 17 is sleeved on the outer side of one end of the plug housing 10, and a limiting protrusion 18 adapted to the plug notch 14 is provided on the inner wall of one end of the connecting ring 17. The number of limiting protrusions 18 is the same as the number of plug notches 14. When the connecting ring 17 is sleeved on the outside of the plug housing 10, the limiting protrusion can enter the mounting groove 13 through the plug notch 14. A number of spaced-apart stop ribs 19 are also provided on the inner wall of the connecting ring 17. The stop ribs 19 and the limiting protrusions 18 are spaced apart. In this embodiment, the plug protrusion 16 has a chamfered angle on one side. When the limiting protrusion is located in the mounting groove 13 through the plug notch 14, the chamfered angle allows the connecting ring 17 to force the limiting protrusion 18 to pass over the plug protrusion 16 and be located on the other side of the plug protrusion 16 when rotating clockwise. At this time, the step of the mounting groove 13 with the plug notch 14 is located between the limiting protrusion and the stop rib 19. The cooperation between the three restricts the connecting ring 17 from disengaging from the plug housing 10, thus achieving locking. When the external male connector is inserted, the connecting ring 17 locks with the male connector. The locking mechanism can be implemented with reference to existing technology, such as providing a hook on the inner wall of the connecting ring 17 and opening a groove on the outer wall of the male connector. Locking is achieved through the cooperation between the hook and the groove. The details are omitted here. On the step with the plug notch 14 in the mounting groove 13, there is also an unlocking notch 15. The number of unlocking notches 15 is the same as the number of limiting protrusions 18. When unlocking is required, rotate the connecting ring 17 clockwise to move the limiting protrusion to the position of the unlocking notch 15. At this time, the connecting ring 17 and the male plug are released from locking, and the male plug can be pulled out. The connecting ring 17 can also be removed as needed. In order to prevent moisture from entering after the male plug is inserted into the plug housing 10, a mating sealing ring 20 is also provided on the outer side of the end of the plug housing 10 with the connecting ring 17. When the male plug is inserted into the plug housing 10, the mating sealing ring 20 is squeezed by the male plug to seal the gap between the male plug and the outer wall of the plug housing 10, thus preventing moisture from entering.

[0020] It should be noted that, in order to make it easier for users to know that the connecting ring 17 is in the unlocked position, a limiting structure, such as a baffle, can be set at the unlocking notch 15. This will prevent the limiting protrusion from rotating after rotating a certain distance in a predetermined direction. At this time, it means that the ring is in the unlocked position.

[0021] Furthermore, to prevent the connecting ring 17 from rotating freely and affecting the stability of the fixation, a return spring 21 is also provided in the mounting groove 13. One end of the return spring 21 abuts against the spaced part of the mounting groove 13, and the other end abuts against the corresponding limiting boss 18 when the connecting ring 17 is installed on the outside of the plug housing 10. When the connecting ring 17 rotates clockwise, it squeezes the return spring 21, and after the connecting ring 17 loses the external force, it resets itself under the force of the return spring 21.

[0022] Furthermore, a cable sleeve assembly 22 is threadedly connected to the end of the plug housing 10 away from the connecting ring 17. The cable sleeve assembly 22 is used to connect and fix the cable to the plug housing 10, while preventing moisture from entering between the plug housing 10 and the cable sleeve assembly 22. A plug sealing ring 221 is also provided between the cable sleeve assembly 22 and the plug housing 10. When the cable sleeve assembly 22 is installed, it will squeeze the plug sealing ring 221 to seal the gap and achieve a sealing effect.

[0023] Furthermore, the cable sleeve assembly 22 includes: a cable outer sleeve 222, one end of which has threads on its inner wall for threaded connection with the end of the plug housing 10 away from the connecting ring 17, and a plug sealing ring 221 located between the cable outer sleeve 222 and the plug housing 10. The other end of the cable outer sleeve 222 also has threads on its outer side, and this end has several slits 225. The slits 225 allow the end of the cable outer sleeve 222 to contract when compressed. A plug tail cap 23 is also threaded onto the cable outer sleeve 222. A cable sleeve sealing ring 223 is located inside the end of the cable outer sleeve 222 with the slits 225. When the plug tail cap 23 is rotated and tightened... When the end with the slit 225 is squeezed, it contracts and compresses the cable sleeve sealing ring 223 to achieve a seal at that end. The tail end of the plug cap 23 will press the cable sleeve sealing ring 223 into the cable outer sleeve 222 to prevent it from coming out. A through hole 224 is also provided in the cable sleeve sealing ring 223. The through hole 224 is used for the cable to pass through and connect to the locking pin 12. When the cable is not connected, a rubber plug 226 is provided in the through hole 224 to block the through hole 224 and prevent debris and moisture from entering. This makes it convenient for users to connect the cables themselves when needed. Since the plug housing 10 has a locking pin 12 inside, users only need to carry crimping pliers and cables to perform wiring and assembly, which is convenient and quick.

[0024] In summary, this application achieves locking and fixing between the male and female connectors through the cooperation of the connecting ring and the plug housing. Locking and unlocking only require rotating the connecting ring, making the operation simple and convenient, and the locking reliable. At the same time, sealing rings are provided at multiple connection points to effectively improve the product's waterproof capability and ensure safe operation of the product in humid environments. Furthermore, multiple locking pins allow users to connect wires on-site, meeting different usage needs.

[0025] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
