Waterproof Connector Boss Insertion for Cable Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional waterproof connectors fail to reliably hold plate-like cables in the width direction, leading to potential instability within the connector housing.
Innovation Solution
A waterproof connector design featuring a holder with protruded bosses that insert into both the connector housing and cable through holes, combined with a sealing member that abuts against these bosses, ensuring stable positioning of the plate-like cable in both width and length directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plate-like cable passes through the slot of the holder, then the cable can be inserted, but the holding of the cable in the width direction is not reliable
Solution Approach 1:
The invention transitions from a single-slot holding mechanism to a multi-point boss insertion mechanism. Multiple bosses protrude from the holder and insert into corresponding through-holes in the cable, providing holding force in multiple dimensions (width direction and length direction) rather than relying on a single slot, thereby achieving reliable positioning in both directions.
2Reliability
If the sealing member is compressed by the sealing member pressing member, then waterproofness is secured, but the cable position may become unsteady
Solution Approach 1:
The holding function is segmented into multiple independent boss-cable through-hole connections distributed at different locations. This segmentation allows each boss to independently provide positioning force, preventing cable displacement while the sealing member is being compressed, thus maintaining cable stability during the waterproofing process.
3Manufacturing precision
If multiple bosses are inserted into connector side through holes and cable side through holes, then cable positioning is improved, but device complexity increases
Solution Approach 1:
The holder integrates multiple functions into a single component: it provides structural support, cable positioning through multiple bosses, and sealing member compression guidance. By merging these functions into one piece rather than using separate components for each function, the invention achieves precise cable positioning without proportionally increasing overall device complexity.

AI summary
A waterproof connector includes a plate-like cable having a plurality of conductor parts, a connector housing having a rectangular insertion opening, a sealing member through which the plate-like cable is inserted and that seals between the insertion opening and the plate-like cable, and a holder that covers an outer periphery of an opening end part of the connector housing, that has a lock part which engages with the opening end part, and that holds the plate-like cable. A plurality of bosses are protruded on the holder and are inserted into a plurality of connector side through holes formed in the opening end part and a plurality of cable side through holes formed in the plate-like cable. A back end surface of the sealing member abuts against the plurality of bosses.
