Technical Field

[0001] This utility model relates to the field of waterproof cable connector technology, specifically to a quick-plug waterproof cable connector. Background Technology

[0002] Waterproof cable connectors, as connecting devices in electrical systems, serve to secure cables and protect them from water. Currently, cables on the market mainly consist of a hexagonal nut, a main connector, and a waterproof gasket. During cable installation, installers typically first manually screw the hexagonal nut into the threaded part of the main connector, then screw the thread into the mounting hole on the circuit board, and finally use tools to tighten the hexagonal nut. The waterproof gasket is then placed between the hexagonal nut and the circuit board. In existing technologies, most connectors are connected by threaded connections. However, if water corrosion occurs, the torque increases after the threads rust, making it difficult to separate the two connectors later. Therefore, this device provides a quick-plug waterproof cable connector. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a quick-plug waterproof cable connector to solve the aforementioned technical problems.

[0004] The present invention adopts the following technical solution: a quick-plug waterproof cable connector, comprising a cable body, a cable connection connector and a plug-in protective shell fixedly installed on one side of the cable body, and a sealing rubber ring fixedly installed on the outer side of the cable connection connector; A mounting bracket is fixedly installed on the inner side of the cable connector. Cable insertion holes are provided on the cable connector, the plug-in protective shell, and the mounting bracket. The cable body is located inside the cable insertion holes. The cable connector also includes a sealant layer, a waterproof insulation layer, and a metal protective layer. The sealant layer is fixedly installed on the cable connector, the waterproof insulation layer is fixedly connected to one side of the sealant layer, and the metal protective layer is fixedly connected to one side of the waterproof insulation layer.

[0005] As a further improvement to the above solution, the cable connector also includes an anti-corrosion coating and an outer protective layer. The anti-corrosion coating is fixedly connected to one side of the metal protective layer, and the outer protective layer is fixedly installed on one side of the anti-corrosion coating.

[0006] As a further improvement to the above solution, multiple springs are fixedly installed on the front and rear sides of the mounting bracket, a sliding plate is fixedly installed on one side of each spring, and a pressing block and an insertion positioning block are fixedly installed on one side of the sliding plate. The pressing block and the insertion positioning block are both slidably installed on the inner side of the cable connector.

[0007] As a further improvement to the above solution, a plug-in groove is provided on one side of the plug-in protective shell, and the insertion positioning block fits into the plug-in groove.

[0008] As a further improvement to the above solution, an insulating rubber pad is fixedly installed on the outside of the pressing block, and a sealing filler is provided at the connection between the cable insertion hole and the cable body.

[0009] As a further improvement to the above solution, the metal protective layer is made of stainless steel, and the anti-corrosion coating is made of polytetrafluoroethylene.

[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: 1. When workers are plugging and unplugging cable connectors and protective housings, they can hold the pressing block with one hand and hold the protective housing with the other hand. By controlling the pressing block to move and slide it into the cable connector, the insertion positioning block can also slide into the cable connector. After the cable connector is slid into the protective housing, the pressing block is released. The springs on both sides can drive the sliding plate and the insertion positioning block to move, allowing the insertion positioning block to slide out from the inside of the cable connector and into the plug-in slot, thus achieving quick plugging and unplugging of the cable connector and protective housing.

[0011] II. The outer protective layer is made of chlorosulfonated polyethylene rubber. This rubber possesses excellent weather resistance, ozone resistance, and chemical corrosion resistance. It maintains stable performance and is not prone to aging or cracking under environmental factors such as ultraviolet radiation, wind, rain, and oil contamination. It also has high tensile and tear strength, effectively resisting external mechanical damage. The outer protective layer is molded or extruded to wrap around the entire cable joint, forming a complete protective sleeve.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] The following is in conjunction with the appendix Figure 1-4 This document provides a detailed description of the technical solutions provided in each embodiment of the present invention.

[0017] This utility model embodiment provides a quick-plug waterproof cable connector, including a cable body 1, a cable connection connector 2 and a plug-in protective shell 3 fixedly installed on one side of the cable body 1, and a sealing rubber ring 4 fixedly installed on the outside of the cable connection connector 2. A mounting bracket 5 is fixedly installed on the inner side of the cable connector 2. Cable insertion holes 6 are provided on the cable connector 2, the plug-in protective shell 3 and the mounting bracket 5. The cable body 1 is located inside the cable insertion hole 6. The cable connector 2 also includes a sealant layer 12, a waterproof insulation layer 13, and a metal protective layer 14. The sealant layer 12 is fixedly installed on the cable connector 2, the waterproof insulation layer 13 is fixedly connected to one side of the sealant layer 12, and the metal protective layer 14 is fixedly connected to one side of the waterproof insulation layer 13.

[0018] In a further preferred embodiment of the present invention, the cable connector 2 further includes an anti-corrosion coating 15 and an outer protective layer 16. The anti-corrosion coating 15 is fixedly connected to one side of the metal protective layer 14, and the outer protective layer 16 is fixedly installed on one side of the anti-corrosion coating 15.

[0019] In a further preferred embodiment of this utility model, multiple springs 7 are fixedly installed on the front and rear sides of the mounting bracket 5, a sliding plate 8 is fixedly installed on one side of the spring 7, and a pressing block 9 and an insertion positioning block 10 are fixedly installed on one side of the sliding plate 8. The pressing block 9 and the insertion positioning block 10 are both slidably installed on the inner side of the cable connector 2.

[0020] Furthermore, the springs 7 on both sides can drive the sliding plate 8 and the insertion positioning block 10 to move, and allow the insertion positioning block 10 to slide out from the inside of the cable connector 2, so that the insertion positioning block 10 can slide into the inside of the insertion slot 11, thereby realizing the quick insertion and removal of the cable connector 2 and the insertion and removal protective shell 3.

[0021] In a further preferred embodiment of the present invention, a plug-in groove 11 is provided on one side of the plug-in protective shell 3, and the insertion positioning block 10 fits into the plug-in groove 11.

[0022] Furthermore, when the operator is plugging and unplugging the cable connector 2 and the plug-and-unplug protective housing 3, he / she can hold the pressing block 9 with one hand and take the plug-and-unplug protective housing 3 with the other hand, and control the pressing block 9 to move and slide into the inside of the cable connector 2. This can also drive the insertion positioning block 10 to slide into the inside of the cable connector 2, allowing the cable connector 2 to slide into the inside of the plug-and-unplug protective housing 3. After sliding in, release the pressing control on the pressing block 9.

[0023] In a further preferred embodiment of this utility model, an insulating rubber pad is fixedly installed on the outside of the pressing block 9, and a sealing filler is provided at the connection between the cable insertion hole 6 and the cable body 1.

[0024] Furthermore, the cable body 1 is installed inside the cable insertion hole 6 above the cable connector 2 and the plug-in protective shell 3. After it is fixed, sealant is filled on the outside to make the connection between the cable body 1 and the cable connector 2 and the plug-in protective shell 3 tighter.

[0025] In a further preferred embodiment of this utility model, the metal protective layer 14 is made of stainless steel, and the anti-corrosion coating 15 is made of polytetrafluoroethylene.

[0026] Furthermore, a polytetrafluoroethylene (PTFE) anti-corrosion coating 15 is applied to the surface of the metal protective layer 14. PTFE is known as the "King of Plastics" because of its extremely low surface free energy, which means it hardly reacts with any chemical substances and has strong resistance to corrosive media such as strong acids, strong alkalis, and strong oxidants. The coating has a smooth surface, making it difficult for dirt and moisture to adhere, thus reducing the chance of corrosive media coming into contact with the metal. At the same time, the PTFE coating has an extremely low coefficient of friction, which reduces friction between components during cable connector insertion and removal operations, reduces wear, and extends the service life of the connector.

[0027] The specific operation is as follows: the cable body 1 is installed inside the cable insertion hole 6 above the cable connector 2 and the plug-in protective shell 3. After it is fixed, sealant is filled on the outside to make the connection between the cable body 1 and the cable connector 2 and the plug-in protective shell 3 relatively tight. When the operator plugs and unplugs the cable connector 2 and the plug-in protective shell 3, he can hold the pressing block 9 with one hand and take the plug-in protective shell 3 with the other hand to control the pressing block 9 to move and slide into the inside of the cable connector 2. This can drive the insertion positioning block 10 to slide into the inside of the cable connector 2, and allow the cable connector 2 to slide into the inside of the plug-in protective shell 3. After sliding in, the pressing control of the pressing block 9 is released. The springs 7 on both sides can drive the sliding plate 8 and the insertion positioning block 10 to move and allow the insertion positioning block 10 to slide out from the inside of the cable connector 2. This allows the insertion positioning block 10 to slide into the inside of the plug-in groove 11, realizing the quick plug-in and unplugging fixation of the cable connector 2 and the plug-in protective shell 3. The sealant layer 12 uses high-performance silicone rubber sealant as the innermost waterproof barrier; silicone rubber has excellent elasticity and weather resistance, and can maintain good flexibility in a wide temperature range of -60℃ to 200℃, which can tightly fill the tiny gaps between the cable connection joint 2 and the plug-in protective shell 3; its molecular structure is stable and does not easily react with water, acids, alkalis and other substances, which can effectively prevent moisture from penetrating into the interior of the cable connection joint 2; The waterproof insulation layer 13 is constructed using thermoplastic polyurethane (TPU). TPU combines the high elasticity of rubber with the high strength of plastic. Its dense molecular structure makes it difficult for water molecules to penetrate, resulting in excellent waterproof performance. The waterproof insulation layer 13 effectively isolates current leakage, ensuring electrical safety. This material also possesses excellent abrasion resistance and tear resistance, resisting frictional damage during frequent insertion and removal of the cable connector 2, preventing waterproof failure due to surface damage. The metal protective layer 14 uses 316L stainless steel as its main material. 316L stainless steel contains molybdenum, which significantly improves its corrosion resistance compared to ordinary stainless steel, maintaining stability even in highly corrosive environments such as seawater and salt spray. The material has a tensile strength exceeding 480 MPa, high hardness, and good toughness, effectively resisting external impacts and compression, protecting the internal waterproof and insulating structures from damage. The metal protective layer 14 is formed through precision stamping or casting processes, tightly fitting with the cable connector 2 to form a robust outer shell. This not only prevents sharp external objects from piercing the cable connector 2 but also provides support for the internal sealing components, enhancing the overall structural stability. A polytetrafluoroethylene (PTFE) anti-corrosion coating 15 is applied to the surface of the metal protective layer 14. PTFE is known as the "King of Plastics" because of its extremely low surface free energy, which means it hardly reacts with any chemical substances and has strong resistance to corrosive media such as strong acids, strong alkalis, and strong oxidants. The coating has a smooth surface, making it difficult for dirt and moisture to adhere, thus reducing the chance of corrosive media coming into contact with the metal. At the same time, the PTFE coating has an extremely low coefficient of friction, which reduces friction between components during cable connector insertion and removal operations, reduces wear, and extends the service life of the connector. The outer protective layer 16 is made of chlorosulfonated polyethylene rubber, which has excellent weather resistance, ozone resistance, and chemical corrosion resistance. Under the influence of environmental factors such as ultraviolet rays, wind, rain, and oil, it maintains stable performance and is not prone to aging or cracking. It has high tensile strength and tear strength, which can effectively resist external mechanical damage. The outer protective layer 16 is wrapped around the entire cable joint 2 through molding or extrusion processes to form a complete protective sleeve. It can not only prevent moisture and corrosive media from entering, but also play a certain role in buffering and reducing the vibration and impact on the joint. In addition, CSM rubber material also has good flame retardant properties, which can enhance the safety of the cable joint in special environments. The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
