Integrated Waterproof Seal Assembly for Detachable Cable Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof sealing solutions for cable connectors and joints, such as cold-shrink tubes and waterproof rubber sleeves, fail to meet the requirements of modern integrated devices due to issues like non-detachability, environmental limitations, and incompatibility with irregular shapes, leading to maintenance difficulties and compromised waterproofing.
Innovation Solution
An integrated waterproof seal connector comprising a rubber tube, a metal snap-fit member, and a plastic support member, designed for detachable and reusable connection with cables and device ports, ensuring long-term stability and environmental resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate seal components are used to ensure waterproofing, then waterproofing reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple separate seal components (grommet, flange seal, and cable seal) into a single integrated waterproof seal assembly. This unified structure maintains the waterproofing functionality of all three seals while eliminating the complexity of assembling and coordinating multiple separate components, thus resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The integrated waterproof seal assembly performs multiple sealing functions simultaneously - grommet sealing, flange sealing, and cable sealing - within a single universal component. This multi-functional design ensures comprehensive waterproofing protection while simplifying the overall device structure by replacing multiple specialized components with one versatile assembly.
2Adaptability or versatility
If multiple seal components are assembled separately, then adaptability to different sealing needs is improved, but ease of operation deteriorates
Solution Approach 1:
By merging the grommet, flange seal, and cable seal into a single pre-assembled unit, the patent maintains the adaptability to address different sealing needs (cable penetration, flange sealing, and gap sealing) while dramatically improving ease of installation. The integrated assembly can be installed as one component rather than requiring separate assembly steps for multiple seals.
3Ease of manufacture
If separate seal components are used, then manufacturing flexibility is improved, but productivity deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-assembling the grommet, flange seal, and cable seal into an integrated waterproof seal assembly during the manufacturing process. This pre-assembly allows each component to be manufactured with optimal flexibility while the final integration is completed once, significantly improving assembly productivity during device manufacturing by reducing the number of assembly steps required.

AI summary
An integrated waterproof seal connector and the use thereof. The integrated waterproof seal connector comprises a metal snap-fit member (10), a plastic support member (20), a rubber tube (30), and a supporting tube member (40). The rubber tube (30) is of a hollow structure and comprises a first hollow structure portion (34), a second hollow structure portion (32) and a connecting portion (31) connecting the first hollow structure portion (34) and the second hollow structure portion (32), which are formed in an integrated manner. The supporting member tube (40) is detachably disposed in the first hollow structure portion (34) and is used to support the first hollow structure portion (34). The metal snap-fit member (10) is detachably disposed in the plastic support member (20), and a press type clamping structure portion (107) is arranged on an end of the metal snap-fit member and can be stuck to a wall of the plastic support member (20). The plastic support member (20) is disposed in the second hollow structure portion (32); a first end of the second hollow structure portion (32) is provided with a seal structure, which can seal a connecting port of a device; and the stuck structure between the plastic support member (20) and the metal snap-fit member (10) protrudes from the first end of the second hollow structure portion (32). The seal connector can achieve long-term reliable waterproof sealing in an outdoor environment.
