Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and more specifically, it relates to a waterproof connector structure. Background Technology

[0002] Cables play a vital role in daily life and industrial applications. Common cables include power cables, communication cables, and electrical equipment wires and cables. The basic structure of a cable typically includes a conductor, an insulation layer, and a protective sheath. The conductor transmits current, the insulation layer prevents current leakage, and the protective sheath protects the cable from mechanical damage and corrosion. Currently, the protective sheath of cables is usually made of PVC plastic, a material with good wear resistance and corrosion resistance, and is widely used in cable manufacturing.

[0003] In existing technologies, PVC plastic is usually crushed first and then processed into cable protective sheaths. However, traditional plastic crushers often result in plastic particles of varying sizes after crushing PVC plastic, which can negatively impact subsequent cable production processes. For example, during extrusion molding, it may lead to uneven product surfaces and uneven internal structures, thereby affecting key quality indicators such as cable insulation performance and mechanical strength, reducing product qualification rate and market competitiveness.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a waterproof connector structure, including a male plug component, a female plug component, and a mating component;

[0006] The male connector assembly includes a first connecting terminal, and a first positioning ring is mounted around one end of the first connecting terminal;

[0007] The female connector assembly includes a second connection terminal, a second positioning ring is mounted around the second connection terminal, and a seal is fitted on the surface of the second connection terminal;

[0008] The mating assembly includes an external threaded sleeve and a threaded cap; the external threaded sleeve is movably fitted onto the surface of the first connecting terminal, and the end of the external threaded sleeve can press against the first positioning ring; the threaded cap is movably fitted onto the surface of the second connecting terminal, and a limiting protrusion is provided at one end of the threaded cap near the second positioning ring, the limiting protrusion can press against the second positioning ring, so that when the external threaded sleeve and the threaded cap are threadedly connected, the male and female components can clamp the seal through the first and second positioning rings.

[0009] The first connecting terminal has multiple insertion holes, and the second connecting terminal has multiple insertion pins, which can be inserted into the insertion holes one by one.

[0010] Each pin has a notch, which divides the corresponding pin into two pins. When the pin is inserted into the socket, the corresponding pins move closer together and have the elasticity to expand outward.

[0011] The connector pins all have an outward tilt angle.

[0012] The end of the connector hole is chamfered to guide the corresponding connector pin into the connector hole.

[0013] The first connecting terminal has a first mating groove at one end, and a plug post is installed in the first mating groove. All plug holes are opened on the plug post. The second connecting terminal has a second mating groove at one end, and the plug post can be inserted into the second mating groove. All plug pins are set in the second mating groove.

[0014] The plug post has a mating concave surface, and the second mating groove has a mating convex surface corresponding to the mating concave surface.

[0015] A first sealing ring is fitted on the first connecting terminal. One end of the first sealing ring is tightly fitted with the first positioning ring, and one end of the external threaded sleeve can contact the first sealing ring.

[0016] The external threaded sleeve is fitted with a second sealing ring, which can contact one end of the threaded cap after the external threaded sleeve is threadedly connected to the threaded cap.

[0017] The second connecting terminal is fitted with a third sealing ring. One end of the third sealing ring is in close contact with one end of the second positioning ring, and the other end of the threaded sleeve can contact the limiting protrusion of the threaded cap.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model uses the threaded connection between the outer spiral sleeve and the threaded cap to compress the sealing element tightly, forming a waterproof barrier at the contact area between the first positioning ring and the second positioning ring. This effectively prevents water from seeping into the interior from the connection point, meeting the requirements of water supply equipment and other usage scenarios for the waterproof performance and electrical connection stability of the connector. This connection method makes the docking and disassembly process relatively simple. Compared with some existing plug connection structures that have good waterproof performance but are cumbersome to install and dock, this device can improve the efficiency of installation and disassembly while ensuring a tight waterproof performance.

[0020] 2. The notch of this utility model divides the connector pin into two connector pins, and the connector pins have an outward tilt angle. When the connector pin is inserted into the connector hole, the inner wall of the connector hole will exert a squeezing effect on the connector pin, causing the corresponding connector pins to come closer together. At the same time, the connector pin itself has outward elasticity. This elasticity allows the connector pin to fit tightly against the inner wall of the connector hole after insertion, realizing electrical connection and ensuring that current or signal can be smoothly transmitted between the two connecting wires through the connector post and connector pin, thus improving the stability of electrical transmission.

[0021] 3. By installing the first sealing ring, the second sealing ring, and the third sealing ring in different positions, when the first connecting end and the second connecting end are connected by the external threaded sleeve and the threaded cap, the first sealing ring, the second sealing ring, and the third sealing ring will also be squeezed into a sealed state, preventing water from entering the plug from different parts and further ensuring waterproof performance.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0030] Please see Figure 1 , Figure 2 As shown:

[0031] This embodiment provides a waterproof connector structure, including a male plug component 1, a female plug component 2, and a mating component 3, characterized in that;

[0032] The male connector assembly 1 includes a first connecting terminal 4, and a first positioning ring 5 is mounted around one end of the first connecting terminal 4;

[0033] The female connector assembly 2 includes a second connecting terminal 6, a second positioning ring 7 is mounted around the second connecting terminal 6, and a sealing element 8 is fitted on the surface of the second connecting terminal 6;

[0034] The mating assembly 3 includes an external threaded sleeve 9 and a threaded cap 10; the external threaded sleeve 9 is movably fitted onto the surface of the first connecting terminal 4, and the end of the external threaded sleeve 9 can press against the first positioning ring 5; the threaded cap 10 is movably fitted onto the surface of the second connecting terminal 6, and a limiting protrusion is provided at one end of the threaded cap 10 near the second positioning ring 7, the limiting protrusion can press against the second positioning ring 7, so that when the external threaded sleeve 9 and the threaded cap 10 are threadedly connected, the male plug assembly 1 and the female plug assembly 2 can clamp the sealing member 8 through the first positioning ring 5 and the second positioning ring 7.

[0035] In practical use, after the first connecting terminal 4 is brought close to and aligned with the second connecting terminal 6, the entire male connector assembly 1 is pushed to insert the first connecting terminal 4 into the second connecting terminal 6. At this time, the external threaded sleeve 9 will come into contact with the threaded cap 10. By rotating the external threaded sleeve 9, it will be threadedly connected to the threaded cap 10. The outer surfaces of the external threaded sleeve 9 and the threaded cap 10 are provided with anti-slip textures, which allows workers to obtain a better grip and greater friction, making it easier to tighten the external threaded sleeve 9 and the threaded cap 10. As the threads are tightened, the external threaded sleeve 9 and the threaded cap 10 gradually approach each other, and the sealing element 8 will be compressed and deformed, tightly fitting the contact area between the first positioning ring 5 and the second positioning ring 7, forming a waterproof barrier. This effectively prevents water from seeping into the interior from the connection point, meeting the requirements of water supply equipment and other usage scenarios for the waterproof performance and electrical connection stability of the connector plug. This connection method makes the docking and disassembly process relatively simple. Compared with some existing plug connection structures with good waterproof performance but cumbersome installation and docking, this device can improve the efficiency of installation and disassembly while ensuring strict waterproof performance.

[0036] like Figure 4 , Figure 5 As shown, the first connecting terminal 4 has multiple insertion holes 11, and the second connecting terminal 6 has multiple insertion pins 12. Each insertion pin 12 can be inserted into a corresponding insertion hole 11. Each insertion pin 12 has a notch 13, which divides the corresponding insertion pin 12 into two insertion leads. When the insertion pin 12 is inserted into the insertion hole 11, the corresponding insertion leads move closer together and have the elasticity to expand outwards. Each insertion lead of the insertion pin 12 has an outward tilting angle. The first connecting terminal 4 and the second connecting terminal 6... When the connector 6 is mated, the connector pin 12 will gradually be inserted into the connector hole 11. Since the connector pin has an outward tilt angle, the inner wall of the connector hole 11 will exert a squeezing effect on the connector pin, causing the corresponding connector pin to come closer to each other. At the same time, the connector pin itself has an outward elasticity. This elasticity allows the connector pin to fit tightly against the inner wall of the connector hole 11 after insertion, realizing electrical connection and ensuring that current or signal can be smoothly transmitted between the two connecting wires through the connector post 15 and the connector pin 12.

[0037] In other embodiments, the internal shape of the socket 11 is conical, so that when the pin 12 is gradually inserted into the socket 11, the pin will contact the inner wall of the socket 11. Because the internal shape of the socket 11 is conical, the pin will be gradually squeezed when inserted, so that the corresponding pins will come closer to each other, thereby making the pins fit tightly against the inner wall of the socket 11, ensuring that current or signal can be smoothly transmitted between the two connecting lines through the socket 11 and the pin 12.

[0038] like Figure 4 , Figure 5 As shown, the end of the plug hole 11 is chamfered to guide the corresponding plug pin 12 into the plug hole 11. When the plug pin 12 approaches the plug hole 11, the chamfer at the end of the plug hole 11 plays a guiding role. It can initially guide and correct the plug pin with an outward tilt angle, making it easier for the plug pin 12 to be aligned with the center position of the plug hole 11.

[0039] like Figure 4 , Figure 5As shown, the first connecting terminal 4 has a first mating groove 14 at one end, and a plug post 15 is installed in the first mating groove 14. All plug holes 11 are opened on the plug post 15. The second connecting terminal 6 has a second mating groove 16 at one end, and the plug post 15 can be inserted into the second mating groove 16. All plug pins 12 are set in the second mating groove 16. The plug post 15 is provided with a mating concave surface, and the second mating groove 16 is provided with a mating convex surface corresponding to the mating concave surface. In the docking of the first connecting terminal 4 and the second connecting terminal 6, the mating concave surface can cooperate with the mating convex surface to play a further positioning and guiding role, ensuring that each plug pin 12 can be accurately inserted into the corresponding plug hole 11, avoiding connection errors and improving docking efficiency.

[0040] like Figure 2 , Figure 4 As shown, a first sealing ring 17 is fitted on the first connecting terminal 4. One end of the first sealing ring 17 is tightly fitted to the first positioning ring 5, and one end of the external threaded sleeve 9 can contact the first sealing ring 17. A second sealing ring 18 is fitted on the external threaded sleeve 9. The second sealing ring 18 can contact one end of the threaded cap 10 after the external threaded sleeve 9 is threadedly connected to the threaded cap 10. A third sealing ring 19 is fitted on the second connecting terminal 6. One end of the third sealing ring 19 is tightly fitted to one end of the second positioning ring 7, and the other end of the threaded sleeve can contact the limiting protrusion of the threaded cap 10. By installing the first sealing ring 17, the second sealing ring 18, and the third sealing ring 19 in different positions, when the first connecting terminal 4 and the second connecting terminal 6 are connected through the external threaded sleeve 9 and the threaded cap 10, the first sealing ring 17, the second sealing ring 18, and the third sealing ring 19 will also be squeezed into a sealed state, preventing water from entering the plug from different parts, thus further ensuring waterproof performance.

[0041] The working principle of the waterproof connector structure provided by this utility model is as follows: After the first connecting terminal 4 is brought close to and aligned with the second connecting terminal 6, the entire male connector assembly 1 is pushed to insert the first connecting terminal 4 into the second connecting terminal 6. At this time, the external threaded sleeve 9 will contact the threaded cap 10. By rotating the external threaded sleeve 9, it will be threadedly connected to the threaded cap 10. As the threads are engaged, the external threaded sleeve 9 and the threaded cap 10 gradually approach each other, and the insertion post 15 of the first connecting terminal 4 will be inserted into the second mating groove 16 of the second connecting terminal 6. Since the insertion pin has an outward tilt angle, the inner wall of the insertion hole 11 will exert a squeezing effect on the insertion pin, causing the corresponding insertion pins to come closer together. At the same time, the insertion pin itself has an outward elasticity. This elasticity allows the insertion pin to fit tightly against the inner wall of the insertion hole 11 after insertion. The fitting achieves electrical connection. After the external threaded sleeve 9 and the threaded cap 10 are threadedly connected, the seal 8 is compressed and deformed, tightly fitting against the contact area between the first positioning ring 5 and the second positioning ring 7, forming a waterproof barrier. At the same time, the first sealing ring 17, the second sealing ring 18, and the third sealing ring 19 are also squeezed into a sealed state, preventing water from entering the plug from different parts, further ensuring waterproof performance, and effectively preventing water from seeping into the interior from the connection point. This meets the requirements of water supply equipment and other usage scenarios for the waterproof performance and electrical connection stability of the connector plug. This connection method makes the docking and disassembly process relatively simple and ensures the stability of the electrical connection. Compared with some existing plug connection structures that have good waterproof performance but are cumbersome to install and dock, this device can improve the efficiency of installation and disassembly while ensuring strict waterproof performance.

[0042] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
