Cable Connector Housing With Rear-Hook Sealing for Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors fail to meet waterproof requirements due to inadequate sealing mechanisms.
Innovation Solution
A cable connector design featuring a front housing with protruding mating tubes and rear housing with receiving cavities and fixing grooves, where cable assemblies pass through and are secured by rear hooks that prevent detachment, combined with a rubber ring for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional locking device is used in the connector housing, then the assembly is simple, but waterproof performance is insufficient
Solution Approach 1:
The locking device is nested within the housing structure, with the locking ball received in a cavity formed in the housing wall. The fixing portion with rear hook is integrated into the housing, eliminating the need for separate external locking mechanisms while achieving both simplicity and waterproof performance.
Solution Approach 2:
A rubber ring is introduced as a flexible sealing element that deforms under compression to create a waterproof seal between the housing and cable assembly. The rubber ring's elasticity allows it to conform to surface irregularities and maintain sealing pressure, achieving waterproof performance without complex mechanical sealing structures.
2Strength
If the connector housing uses a simple structure, then manufacturing is easy, but cable assembly security is insufficient
Solution Approach 1:
The housing is segmented into functional zones: receiving cavities for cable insertion, fixing grooves for locking engagement, and integrated cavities for locking balls. This segmentation allows each zone to be optimized for its specific function while maintaining overall structural simplicity and manufacturability.
Solution Approach 2:
Multiple functions are merged into single structural elements: the fixing portion serves both as a structural support and a locking mechanism via its rear hook; the housing wall integrates both structural and sealing functions by incorporating the locking ball cavity and receiving cable assemblies; the rubber ring combines sealing with cable retention.
