Description

Technical Field

[0001] This application relates to the field of connector tail cap sealing technology, and in particular to rubber clay tail caps for connectors. Background Technology

[0002] With the continuous development of technology, the application range of connectors is becoming increasingly wide, involving many industries such as electronic equipment, automobiles, and communications. Connectors work in various complex environments, and the performance requirements for them are becoming increasingly stringent, especially in terms of waterproofing and dustproofing.

[0003] In the past, the traditional approach to solving the waterproofing and dustproofing issues of connectors was to use traditional tail caps. Traditional tail caps generally have a fixed structure and material design, customized for specific connector models and application environments. During production, relatively standardized tail cap products are typically manufactured using processes such as injection molding. During installation, the tail cap is simply slipped onto the tail of the connector, utilizing the simple seal between the tail cap and the connector to prevent dust and water from entering. This method provides a certain degree of waterproofing and dustproofing, but its application is relatively limited due to its structural and material limitations. Some connectors may not even be equipped with tail caps, leaving a lack of effective solutions when waterproofing and dustproofing are required.

[0004] Traditional tail caps have limited application environments, suitable only for specific connectors and environmental conditions. They cannot be flexibly adjusted to different usage environments and offer poor waterproofing and dustproofing, making them unsuitable for applications with high waterproofing and dustproofing requirements. For connectors operating in complex environments, traditional tail caps cannot provide adequate sealing performance, easily allowing dust and water to intrude and affecting the normal operation of the connector. Utility Model Content

[0005] To address the shortcomings of traditional tail caps, such as their inability to adapt to different environments and poor waterproofing and dustproofing, this application provides a rubber clay tail cap with a connector.

[0006] The rubber end cap of the connector provided in this application adopts the following technical solution: The connector's rubber cap includes a first tail clip, a second tail clip, and a cement-resistant limiting part. The first tail clip and the second tail clip are connected by a locking element to lock their ends and middle. The ends of the first tail clip and the second tail clip are also connected by a plastic part. The first tail clip and the second tail clip fit together to form a closed first port and a second port, respectively. The first port and the second port are connected to form a flow channel. The cement-resistant limiting part is elastically installed on the first port to limit the cement from wrapping around the inner wall of the first tail clip / second tail clip.

[0007] By adopting the above technical solution, the rubber cap of the connector can be used in some capless connectors to provide dust and water protection; the first and second tail clips are connected by locking fasteners and plastic parts, which can effectively lock the ends and middle of both, ensuring the stability of the tail clip structure; the enclosed first and second ports are connected to form a flow channel, which facilitates the passage of cables; the elastic cement-proof limiting part is installed on the first port, which can limit the cement-proof wrapping around the inner wall of the tail clip, ensuring cement-proof fixation and enhancing the waterproof and dustproof effect.

[0008] Optionally, the locking member has a first engaging portion and a second engaging portion.

[0010] Optionally, the first fastening part includes a protruding buckle and a locking ring. The protruding buckle is installed at the end of the first tail clip, and the locking ring is installed at the end of the second tail clip. The protruding buckle and the locking ring are engaged in a snap-fit ​​relationship.

[0011] By adopting the above technical solution, the first and second tail clips of the connector's rubber cap can be effectively locked, so that the first and second tail clips fit together to form a closed port and flow channel. The cement-proof limiting part can limit the cement wrapping on the inner wall, which plays a role in dust and water protection. At the same time, the buckle of the protrusion and the locking ring can firmly connect the ends of the first and second tail clips, ensuring the stability of the cap structure.

[0012] Optionally, the second fastening part includes a fastening block integrally formed on the first tail clip and a mating buckle integrally formed on the second tail clip, wherein the fastening block and the mating buckle engage in a snap-fit ​​relationship.

[0013] By adopting the above technical solution, the fastening block and the mating buckle are interlocked, so that the middle position of the first tail clip and the second tail clip is locked.

[0014] Optionally, the first port has an oblong shape, the second port has a circular shape, and the diameter of the first port is larger than the diameter of the second port.

[0015] By adopting the above technical solutions, the rubber cap of the connector can be adapted to connection parts of different shapes and sizes, thus better meeting the needs of different usage environments.

[0016] Optionally, a partition strip is formed on the inner wall of the first port, and the partition strip is integrally formed with the first tail clip and the second tail clip.

[0017] By adopting the above technical solutions, the stability of the tail cap can be enhanced, and the overall connection stability can be improved.

[0018] Optionally, a rib is formed on the inner wall of the second port, the rib and the first tail clip are integrally formed, and the second port of the second tail clip is smooth.

[0019] By adopting the above technical solution, the contact stability between the second port and components such as cables is enhanced.

[0020] Optionally, an annular plate extends from the end of the second tail clip, and a perforation is provided on the annular plate.

[0021] By adopting the above technical solution, the extended length forms a semi-circular plate-like structure, making installation, disassembly, and pairing more convenient.

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses a rubber clay end cap for a connector.

[0030] Reference Figure 1 and Figure 2 As shown, the device includes a first tail clip 1, a second tail clip 2, a cement-resistant limiting part 3, a locking element 4, and a plastic part 5. The first tail clip 1 and the second tail clip 2 are connected by the locking element 4, locking their ends and middle sections together. The ends are also connected by the plastic part 5. The first tail clip 1 and the second tail clip 2 fit together to form a closed first port 6 and a closed second port 7, respectively. The first port 6 and the second port 7 communicate to form a flow channel. The cement-resistant limiting part 3 is elastically mounted on the first port 6 to limit cement from wrapping around the inner wall of the first tail clip 1 / second tail clip 2, allowing the tail cap to better adapt to different connectors and usage environments, effectively improving waterproof and dustproof performance. This is because the connection between the locking element 4 and the plastic part 5 ensures the stability of the tail clip connection, and the cement-resistant limiting part 3 ensures effective cement-resistant installation and use.

[0031] join Figure 2 As shown, the first tail clip 1 and the second tail clip 2 are the main structural components of the tail cap. The first tail clip 1 is typically made of a plastic material with certain strength and toughness, such as polycarbonate (PC), which has high strength and good impact resistance, and can maintain structural integrity in different usage environments. It can also be made of polypropylene (PP), which has advantages such as light weight and corrosion resistance. The second tail clip 2 can also be made of the above material and matches the first tail clip 1. The shape of the first tail clip 1 and the second tail clip 2 is determined according to the shape of the connector and installation requirements, and is generally semi-enclosed so that they fit together to form a closed port.

[0032] See Figure 1 and Figure 2As shown, the locking component 4 includes a first engaging part 41 and a second engaging part 42. The first engaging part 41 is used to lock the ends of the first tail clip 1 and the second tail clip 2. It includes a protruding buckle 411 and a locking ring 412. The protruding buckle 411 is generally cylindrical with a certain curvature at the head for easy locking. It is installed at the end of the first tail clip 1 and is integrally molded with the first tail clip 1 through injection molding to ensure a firm connection. The locking ring 412 is installed at the end of the second tail clip 2 and has a ring structure. Its inner diameter is adapted to the outer diameter of the protruding buckle 411. When the protruding buckle 411 is inserted into the locking ring 412, a tight locking fit can be achieved. The protruding buckle 411 can also be square or other shapes, and the shape of the locking ring 412 can be adjusted accordingly. The second fastening part 42 is used to lock the middle part of the first tail clip 1 and the second tail clip 2. It includes a fastening block 421 integrally formed on the first tail clip 1 and a mating buckle 422 integrally formed on the second tail clip 2. The fastening block 421 has a block structure with certain protrusions on the surface, and the mating buckle 422 has a groove that matches the protrusions. When the two are fastened together, they can effectively prevent the first tail clip 1 and the second tail clip 2 from separating in the middle position. The fastening block 421 and the mating buckle 422 can also be connected by other mating methods such as magnetic adsorption.

[0033] See Figure 1 and Figure 2 As shown, the plastic part 5 serves to assist in connecting the ends of the first tail clip 1 and the second tail clip 2. It is generally made of rubber and has good elasticity and flexibility. The plastic part 5 is connected to the ends of the first tail clip 1 and the second tail clip 2 respectively, further enhancing the stability of the connection between the two.

[0034] See Figure 1 and Figure 3 As shown, the first port 6 and the second port 7 are important components of the tail cap. The first port 6 has an oblong shape to accommodate connectors with special shapes. Spacers 8 are formed on its inner wall, and are integrally formed with the first tail clip 1 and the second tail clip 2. The function of the spacers 8 is to increase friction, allowing the cement-resistant limiting part 3 to be more securely installed on the first port 6. The spacers 8 are generally strip-shaped and evenly distributed on the inner wall, but can also be spiral or other shapes. The second port 7 has a circular shape, smaller than the diameter of the first port 6, to better accommodate connectors of different thicknesses. Ribs 9 are formed on the inner wall of the second port 7, integrally formed with the first tail clip 1. The ribs 9 are strip-shaped, increasing the contact area between the second port 7 and the connector, improving connection stability. The second port 7 of the second tail clip 2 is smooth, reducing friction with the connector and facilitating installation.

[0035] See Figure 2 and Figure 3As shown, the cement-resistant limiting part 3 is a key component that effectively limits the rubber cement to achieve dustproof and waterproof functions. It can be a sheet-like structure or a bent shape, possessing good elasticity to tighten the rubber cement. The rubber cement material has excellent adhesion to metals and various cable sheath materials, and good conformability to irregular surfaces, allowing it to be adjusted according to the shape of the connector. In use, simply tear off the release paper and wrap the cement around the first port 6, pressing it between layers. PVC electrical tape is then wrapped around the outside for mechanical protection. The cement-resistant limiting part 3 has a split structure and is locked by multi-segment locking fasteners 4, facilitating installation and disassembly.

[0036] See Figure 3 As shown, an annular plate 10 extends from the end of the second tail clip 2, and the annular plate 10 has a through hole. The annular plate 10 is generally made of the same material as the second tail clip 2 and is integrally formed. The purpose of the through hole is to facilitate threading or installing other auxiliary components, such as installing a positioning rope through the through hole to better fix the position of the tail cap.

[0037] The implementation principle of the rubber cement tail cap of the connector in this application embodiment is as follows: through the cooperation of the first tail clip 1 and the second tail clip 2, the locking part 4 and the plastic part 5 are connected to form a stable structure. The different shapes of the first port 6 and the second port 7 can be adapted to different connectors. The cement-proof limiting part 3 effectively limits the rubber cement, avoiding the tangling of the wire harness, while giving it good dustproof and waterproof performance. Compared with traditional tail caps, it can adapt to different usage environments, has better waterproof and dustproof effects, and can meet the dustproof and waterproof requirements of some unconventional connectors, thus improving the practicality and reliability of the tail cap overall.
