Description

Technical Field

[0001] This application relates to the field of dual waterproof sealing connection technology, and in particular to a connector with multiple waterproof sealing structures. Background Technology

[0002] Connectors play a crucial role in the field of electronic equipment and electrical systems. With the continuous development of technology, the application scenarios of electronic equipment are becoming increasingly widespread, from various household appliances to complex mechanical equipment in industrial production; all rely on connectors to achieve the transmission of power and signals. The performance of connectors directly affects the stability and reliability of the entire system; their quality is related to whether the equipment can operate normally, and is of great significance for ensuring the efficient and safe operation of electronic equipment and electrical systems.

[0003] In traditional connector designs, a single sealing structure is typically used to achieve waterproofing. Some connectors incorporate simple gaskets at critical points, using the pressure between the gasket and the connecting components to prevent moisture ingress. Others apply sealant to the connector interface, utilizing its adhesive and filling properties to achieve waterproofing. Still others employ rubber rings for sealing, installing them in specific locations and relying on their elasticity to create a seal.

[0004] However, these traditional waterproof sealing methods have certain drawbacks. A single sealing structure can only seal a part of the connector and cannot effectively seal and protect multiple critical parts of the connector at the same time. When encountering harsh environments, such as high humidity or rain immersion, moisture can easily enter the connector from unsealed or weakly sealed parts, thereby affecting the performance of the connector and even causing damage to the connector, affecting the normal operation of the entire electronic device or electrical system. Utility Model Content

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a connector with multiple waterproof sealing structures.

[0031] Reference Figure 1 The connector includes a housing 1, a cylinder 2, and a seal 3. The cylinder 2 is mounted on the housing 1, and the seal 3 is mounted on the end face of the housing 1. This structural arrangement enables the connector to seal and protect multiple key parts, preventing moisture from entering the connector and affecting its performance. This is because the components work together to form a multi-layered sealing structure.

[0032] Specifically, the cylinder body 2 is internally equipped with a terminal assembly 4, which is used for the transmission of power and signals. The terminal assembly 4 can be composed of a conductive metal sheet and insulating plastic. The conductive metal sheet is responsible for conducting current and signals, while the insulating plastic provides isolation and protection, preventing leakage and short circuits. In some alternative solutions, the conductive metal sheet can also be made of materials with good conductivity, such as copper alloy, and the insulating plastic can be made of different materials depending on the actual needs. The cylinder body 2 has positioning parts 11 on both sides. The positioning parts 11 are used to accurately install the cylinder body 2, ensuring the positional accuracy of the cylinder body 2 on the housing 1. The positioning parts 11 can be positioning protrusions, which cooperate with corresponding positioning grooves on the housing 1 to achieve positioning; or they can be positioning holes, connected to the housing 1 via positioning pins.

[0033] Specifically, the housing 1 has mounting portions 12 around its perimeter, which are used to mount other components. The mounting portions 12 form threaded holes to facilitate installation using bolts or other fasteners. In some alternative designs, the mounting portions 12 can also be snap-fit ​​structures, allowing connection to other components via snap-fit.

[0034] Specifically, the seal 3 has multiple sealing sections 13 for sealing multiple parts of the housing 1. Each sealing section 13 has sealing units for sealing multiple parts, including a first sealing unit 31 mounted around the mounting section 12, a second sealing unit 32 mounted on both sides of the cylinder 2, and a third sealing unit 33 mounted on the end face of the housing 1. This multi-stage sealing unit arrangement allows for simultaneous sealing of multiple critical parts of the connector, significantly improving waterproofing.

[0035] The first sealing unit 31 is installed around the mounting portion 12 to seal the area around the mounting portion 12 and prevent moisture from entering from the mounting portion 12. The first sealing unit 31 can be an annular sealing gasket made of rubber, which has good elasticity and sealing performance. In some alternative solutions, other materials with sealing properties, such as silicone, can also be used.

[0036] The second sealing unit 32 includes a straight sealing strip 321 installed on one side of the cylinder body 2 and an arc-shaped sealing strip 322 installed on the other side of the cylinder body 2. The straight sealing strip 321 and the arc-shaped sealing strip 322 can better conform to the shape of the cylinder body 2 and seal both sides of the cylinder body 2. The straight sealing strip 321 and the arc-shaped sealing strip 322 can be made of rubber and installed on both sides of the cylinder body 2 by adhesive or snap-fit. In some alternative solutions, other elastic sealing materials can also be used. The first sealing unit 31 is arranged in a ring at the entrance end of the threaded hole, further strengthening the seal on the mounting part 12.

[0037] The third sealing unit 33 includes a sealing groove 331 formed on the end face of the housing 1 and a sealing strip 332 embedded in the sealing groove 331. The sealing strip 332 is arranged in a U-shape. This U-shape arrangement can provide a complete seal to the end face of the housing 1. The sealing strip 332 has an I-shaped or rectangular cross-section, and the contact between the sealing strip 332 and the sealing groove 331 is either line contact or surface contact. The I-shaped sealing strip 332 can provide better elasticity and sealing performance, while the rectangular sealing strip 332 is easier to process and install. Point contact can reduce friction and facilitate installation and disassembly; surface contact can provide a wider sealing area and improve the sealing effect. The height of the third sealing unit 33 is equal to the height of the second sealing unit 32, and the height of the second sealing unit 32 is higher than that of the first sealing unit 31. This height setting can form a stepped sealing structure, further enhancing the sealing effect.

[0038] In addition, reinforcing ribs 5 are installed on both sides of the cylinder body 2. The reinforcing ribs 5 can improve the structural strength of the cylinder body 2 and prevent the cylinder body 2 from deforming when subjected to external forces, thereby ensuring the normal operation of the terminal assembly 4. The reinforcing ribs 5 can be triangular or rectangular in structure and are connected to the cylinder body 2 by welding or integral molding.

[0039] The implementation principle of a connector with a multiple waterproof sealing structure in this embodiment is as follows: A multiple sealing structure is formed through the cooperation of the housing 1, the cylinder 2, and the seal 3. The multi-level sealing unit simultaneously seals and protects multiple key parts of the connector, effectively preventing moisture from entering the connector. The reinforcing rib 5 improves the structural strength of the cylinder 2, ensuring the stability and reliability of the connector. Compared to traditional connectors with a single sealing structure, the connector in this embodiment has significantly improved waterproof performance and structural strength, better adapting to harsh environments and ensuring the normal operation of electronic equipment and electrical systems.
