Integrated Seal Ring for Compact Laser Radar Connector Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector designs for laser radar systems are complex and voluminous due to the need for separate cable seals and housing seals within the inner and outer housings, which complicates waterproof sealing and modern system packaging.
Innovation Solution
A connector housing assembly that integrates an inner housing with terminal mounting holes, a cable seal within the inner housing for sealing with the cable, and a housing seal on the outer side of the inner housing for sealing with the mating connector, simplifying the structure while maintaining effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cable seal and housing seal are arranged within inner housing and outer housing respectively, then waterproof sealing function is achieved, but connector structure becomes complicated and volume increases
Solution Approach 1:
The patent combines the cable seal and housing seal into a single integrated seal assembly. The seal ring is positioned to simultaneously seal both the cable penetration area and the interface between inner and outer housings, eliminating the need for separate seal components and reducing structural complexity while maintaining waterproof integrity.
Solution Approach 2:
The single seal ring performs multiple sealing functions: it seals the cable where it penetrates the housing and simultaneously seals the interface between the inner and outer housings. This multi-functional seal component replaces what would traditionally require separate cable seal and housing seal elements.
2Reliability
If separate cable seal and housing seal are arranged within inner housing and outer housing respectively, then waterproof sealing function is achieved, but connector volume becomes too large for modern system packaging
Solution Approach 1:
The patent merges the cable seal and housing seal into one integrated seal structure that occupies a single spatial location. This consolidation eliminates the volume required for separate seal components and their individual mounting spaces, reducing the overall connector volume to make it suitable for modern compact system packaging.
Solution Approach 2:
The seal ring is nested within the housing structure such that it simultaneously addresses multiple sealing requirements without requiring additional external space. The single seal component is positioned to seal both the cable penetration and the housing interface within the same spatial envelope.
3Reliability
If cable seal is installed in inner housing, then sealing between inner housing and cable is achieved, but structure complexity increases
Solution Approach 1:
The patent integrates the cable sealing function into the housing seal assembly rather than using a separate cable seal component. The seal ring is positioned within the inner housing to seal the cable penetration while being part of the same sealing system that seals the housing interface, simplifying the overall structure.
4Reliability
If housing seal is provided within outer housing, then sealing between outer housing and mating housing is achieved, but structure complexity increases
Solution Approach 1:
The patent combines the housing seal function with the cable seal function into a single seal ring assembly. The same seal ring that seals the cable penetration also seals the interface between the outer housing and the mating connector housing, eliminating the need for a separate housing seal component.

AI summary
A connector housing assembly includes an inner housing, a cable seal and a housing seal. The inner housing defines a plurality of terminal mounting holes for fixedly mounting a plurality of terminals. The cable seal is installed in the inner housing and is adapted to form a seal between the inner housing and a cable extending into the inner housing. The housing seal is sleeved on an outer side of the inner housing and is adapted to form a seal between the inner housing and a mating housing of a mating connector.
