Waterproof Connector With Split Fastening Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof connectors for cables are complex, costly, and inflexible, requiring pre-determined cable lengths and lacking uniform adherence, making on-site adjustments and efficient wiring operations difficult.
Innovation Solution
A waterproof connector design featuring a housing with a terminal insertion point, a waterproof tube across the housing and cable periphery, and a splitable fastening cover that sandwiches the tube, ensuring secure adhesion and allowing for adjustable cable lengths without pre-forming the connector unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polyethylene based elastomers are molded around cable cores with rubber based elastomers to assure adherence, then waterproofing is improved, but production costs increase and device complexity increases
Solution Approach 1:
The connector is divided into separate components: the housing with cable management portion, the waterproof tube, and the fastening cover. This segmentation allows each component to be manufactured independently and assembled later, reducing overall device complexity while maintaining waterproofing effectiveness through the integrated waterproof tube and fastening cover mechanism.
2Reliability
If polyethylene based elastomers are molded around cable cores with rubber based elastomers to assure adherence, then waterproofing is improved, but production costs increase
Solution Approach 1:
By segmenting the connector into separable components (housing, waterproof tube, fastening cover), the manufacturing process is simplified. Each component can be produced using standard molding techniques and assembled through straightforward insertion and fastening operations, reducing production costs compared to complex multi-material molding processes.
Solution Approach 2:
The waterproof tube acts as an intermediary component between the housing and cable, providing a simple yet effective waterproof barrier. This intermediary structure achieves reliable waterproofing without requiring complex multi-layer elastomer bonding processes, thereby reducing manufacturing complexity and cost.
3Ease of manufacture
If the housing is formed in advance as a unit on the end part of the cable, then cable length cannot be adjusted on-site, but connector assembly is simplified
Solution Approach 1:
The connector is designed as separable components that can be assembled after cable installation. The housing, waterproof tube, and fastening cover can be attached to cables of any length, providing on-site adaptability while maintaining simple assembly procedures through the modular design.
Solution Approach 2:
The connector design allows for dynamic adjustment of cable length on-site. The separable components enable installers to cut cables to the required length and then assemble the connector components, providing flexibility and adaptability rather than requiring pre-formed fixed-length assemblies.
4Ease of operation
If a screw cover is applied to fasten the cable to the connector, then cable fastening is achieved, but uniform adherence around the entire circumference cannot be controlled
Solution Approach 1:
The fastening mechanism is segmented into multiple interaction points between the fastening cover and housing. The cover includes positioning protrusions that engage with corresponding recesses, distributing the fastening force uniformly around the circumference. This segmented engagement ensures uniform cable adherence without requiring complex screw tightening control.
