Technical Field
[0001] This utility model belongs to the field of connector technology, specifically relating to a combined waterproof connector. Background Technology
[0002] In electrical engineering, a plug is an interface device used to connect two or more electrical devices, components or systems. The plug forms an electrical connection by mating with the corresponding socket or device interface through its internal contacts. When the plug is inserted into the socket, the contacts make contact with each other and conduct current or signal; when the plug is pulled out, the contacts separate and cut off the current or signal.
[0003] Existing connectors combine male and female plugs in a plug-and-play manner, resulting in poor sealing and waterproofing. Water can easily enter the connectors during operation, leading to short circuits and other issues in the electrical system. Utility Model Content
[0004] The purpose of this invention is to provide a modular waterproof connector that solves the problems of existing connectors that combine male and female plugs in a plug-and-play manner, resulting in poor sealing, inadequate waterproofing, and easy water ingress during operation, which can lead to short circuits in the circuit system.
[0005] The specific technical solution adopted in this utility model is as follows: A modular waterproof connector, comprising a male plug and a female plug; A splicing assembly is disposed between a male plug and a female plug. The splicing assembly includes a first sleeve, a second sleeve, a third sleeve, a positioning rod, and a positioning groove. The first sleeve is disposed through the outer side of the male plug, and the second sleeve is disposed through the outer side of the female plug. The third sleeve is disposed through the outer sides of the first sleeve and the second sleeve. A positioning rod is fixedly disposed on the side of the male plug closer to the female plug, and a positioning groove adapted to the positioning rod is disposed on the side of the female plug closer to the male plug. The positioning rod is slidably connected to the female plug through the positioning groove. The splicing assembly is used to combine and fix the male plug and the female plug. A sealing assembly is disposed on the outside of the male and female plugs. The sealing assembly includes a first fixing ring, a first rubber sealing ring, a connecting ring, a collar, a second fixing ring, and a second rubber sealing ring. The first fixing ring and the first rubber sealing ring are disposed through the outside of the male plug. A connecting ring is fixedly disposed on the side of the third sleeve, and a collar is fixedly disposed on the other side of the connecting ring. The second fixing ring and the second rubber sealing ring are disposed through the outside of the female plug. The sealing assembly is used to improve the sealing effect of the splicing assembly.
[0006] In a preferred embodiment, wires are electrically connected to the sides of the male and female plugs that are far apart from each other. A protrusion is installed on the side of the male plug closer to the female plug, and a slot for adapting the protrusion is provided on the side of the female plug closer to the male plug.
[0007] In a preferred embodiment, the male plug is fixedly connected to the first sleeve, the female plug is fixedly connected to the second sleeve, the third sleeve has an internal thread on its inner side, and the first and second sleeves each have an external thread adapted to the internal thread on their outer sides. The first and second sleeves are respectively threadedly connected to the third sleeve.
[0008] In a preferred embodiment, the male plug is fixedly connected to the first fixing ring, the first fixing ring is fixedly connected to the first rubber sealing ring, the side of the collar is provided with a through groove adapted to the female plug, the female plug passes through the through groove and is movably connected to the collar, the female plug is fixedly connected to the second fixing ring, and the second fixing ring is fixedly connected to the second rubber sealing ring.
[0009] The technical effects achieved by this utility model are as follows: This utility model, by setting up a splicing component, brings the male plug close to the female plug so that the protruding seat is engaged into the slot. The positioning rod, in conjunction with the positioning groove, allows the male plug to be quickly aligned with the female plug. When the male plug contacts the female plug, the external thread of the first sleeve is just aligned with the external thread of the second sleeve. Rotating the third sleeve makes the third sleeve threadedly connected to the first sleeve, which can fix the relative position of the male plug and the female plug, thus completing the combination of the male plug and the female plug. This invention, by setting a sealing component, allows the third sleeve to move closer to the first rubber sealing ring during the threaded connection between the third sleeve and the first sleeve. Simultaneously, the collar moves closer to the second rubber sealing ring. When the third sleeve contacts the first rubber sealing ring, the collar just contacts the second rubber sealing ring. Continuing to rotate the third sleeve allows it to clamp the first rubber sealing ring with the first fixing ring, while the collar clamps the second rubber sealing ring with the second fixing ring. This seals the ends of the third sleeve and collar that are far apart from each other, improving the sealing performance of the male and female plug connection and providing better waterproofing.

[0018] In a preferred embodiment, please refer to Figures 1 to 4A splicing assembly is provided between the male plug 1 and the female plug 2. The splicing assembly consists of a first sleeve 3, a second sleeve 4, a third sleeve 5, a positioning rod 7, and a positioning groove 9. The first sleeve 3 is provided through the outside of the male plug 1, and the second sleeve 4 is provided through the outside of the female plug 2. The third sleeve 5 is provided through the outside of the first sleeve 3 and the second sleeve 4. The positioning rod 7 is fixedly provided on the side of the male plug 1 near the female plug 2. The positioning groove 9 that is adapted to the positioning rod 7 is provided on the side of the female plug 2 near the male plug 1. The positioning rod 7 is slidably connected to the female plug 2 through the positioning groove 9.
[0019] In this embodiment, the male plug 1 is fixedly connected to the first sleeve 3, the female plug 2 is fixedly connected to the second sleeve 4, the inner side of the third sleeve 5 is provided with an internal thread, and the outer sides of the first sleeve 3 and the second sleeve 4 are both provided with external threads adapted to the internal threads. The first sleeve 3 and the second sleeve 4 are respectively threadedly connected to the third sleeve 5.
[0020] In this embodiment, the protruding seat 6 and the positioning rod 7 are aligned with the slot 8 and the positioning groove 9, respectively. The male plug 1 is brought close to the female plug 2 so that the protruding seat 6 is engaged inside the slot 8. The positioning rod 7, in conjunction with the positioning groove 9, allows the male plug 1 to quickly align with the female plug 2. When the male plug 1 contacts the female plug 2, the external thread of the first sleeve 3 is just aligned with the external thread of the second sleeve 4. The third sleeve 5 is rotated so that the third sleeve 5 is threadedly connected to the first sleeve 3, which can fix the relative position of the male plug 1 and the female plug 2, thus completing the combination of the male plug 1 and the female plug 2.
[0021] In a preferred embodiment, please refer to Figures 1 to 4 The male plug 1 and the female plug 2 are provided with sealing components on their outer sides. The sealing components consist of a first fixing ring 10, a first rubber sealing ring 11, a connecting ring 12, a collar 13, a second fixing ring 14, and a second rubber sealing ring 15. The first fixing ring 10 and the first rubber sealing ring 11 are provided through the outer side of the male plug 1. The connecting ring 12 is fixedly provided on the side of the third sleeve 5, and the collar 13 is fixedly provided on the other side of the connecting ring 12. The second fixing ring 14 and the second rubber sealing ring 15 are provided through the outer side of the female plug 2.
[0022] In this embodiment, the male plug 1 is fixedly connected to the first fixing ring 10, the first fixing ring 10 is fixedly connected to the first rubber sealing ring 11, the side of the collar 13 is provided with a through groove adapted to the female plug 2, the female plug 2 passes through the through groove and is movably connected to the collar 13, the female plug 2 is fixedly connected to the second fixing ring 14, and the second fixing ring 14 is fixedly connected to the second rubber sealing ring 15.
[0023] In this embodiment, during the threaded connection between the third sleeve 5 and the first sleeve 3, the rotation of the third sleeve 5 causes it to move along the outer surfaces of the first sleeve 3 and the second sleeve 4. The movement of the third sleeve 5 drives the connecting ring 12 and the collar 13 to move. When the third sleeve 5 moves towards the first rubber sealing ring 11, the collar 13 simultaneously moves towards the second rubber sealing ring 15. When the third sleeve 5 contacts the first rubber sealing ring 11, the collar 13 just contacts the second rubber sealing ring 15. Continuing to rotate the third sleeve 5 allows it to clamp the first rubber sealing ring 11 with the first fixing ring 10, while the collar 13 clamps the second rubber sealing ring 15 with the second fixing ring 14. This seals the ends of the third sleeve 5 and the collar 13 that are far apart from each other, improving the sealing performance of the connection between the male plug 1 and the female plug 2 and providing better waterproofing. Reverse rotation of the third sleeve 5, causing it to disengage from the first sleeve 3, releases the fixation on the male plug 1 and the female plug 2, making it easy to separate them.
[0024] The working principle of this utility model is as follows: When using this device, align the protruding seat 6 and the positioning rod 7 to the slot 8 and the positioning groove 9 respectively. Bring the male plug 1 close to the female plug 2 so that the protruding seat 6 engages inside the slot 8. When the male plug 1 contacts the female plug 2, the external thread of the first sleeve 3 aligns perfectly with the external thread of the second sleeve 4. Rotate the third sleeve 5 to thread it onto the first sleeve 3, thus fixing the relative positions of the male plug 1 and the female plug 2, completing the assembly of the male plug 1 and the female plug 2. During the threaded connection between the third sleeve 5 and the first sleeve 3, the rotation of the third sleeve 5 causes it to move along the outer surfaces of the first sleeve 3 and the second sleeve 4. This movement of the third sleeve 5 drives the connecting ring 12 and the collar 13 to move. When the third sleeve 5 moves closer to the first sleeve 4... When the rubber sealing ring 11 moves in one direction, the collar 13 moves towards the second rubber sealing ring 15. When the third sleeve 5 contacts the first rubber sealing ring 11, the collar 13 just contacts the second rubber sealing ring 15. Continuing to rotate the third sleeve 5 can make the third sleeve 5 cooperate with the first fixing ring 10 to clamp the first rubber sealing ring 11. At the same time, the collar 13 cooperates with the second fixing ring 14 to clamp the second rubber sealing ring 15, thereby sealing the ends of the third sleeve 5 and the collar 13 that are far apart from each other, improving the sealing performance of the connection between the male plug 1 and the female plug 2, and providing a better waterproof effect. Reverse rotation of the third sleeve 5 can cause the third sleeve 5 to disengage from the first sleeve 3, thereby releasing the fixation of the male plug 1 and the female plug 2, making it convenient to separate the male plug 1 and the female plug 2.
