Hybrid Connector Housing for EMI Shielding and Easier Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for laser radar systems require separate sub-housings for Ethernet signal and power supply terminals, increasing cost and complicating assembly due to the need for a shield connection member between mating connectors.
Innovation Solution
A hybrid connector housing with an integrally formed inner housing comprising a rear housing and two sub-housings, each accommodating different cable assemblies, allowing simultaneous transmission of signals and power while maintaining electromagnetic interference protection through a unified design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing is designed as two separate sub housings for Ethernet signal terminal and power supply terminal, then electromagnetic interference protection is achieved, but manufacturing cost increases and assembly difficulty increases
Solution Approach 1:
The housing is divided into a first sub-housing for accommodating the Ethernet signal terminal and a second sub-housing for accommodating the power supply terminal and other signal terminals. This segmentation allows independent design and assembly of each sub-housing while maintaining electromagnetic interference protection through the shield connection member that connects the two sub-housings.
2Reliability
If the housing is designed as two separate sub housings, then electromagnetic interference protection is achieved, but manufacturing cost increases
Solution Approach 1:
The shield connection member is designed to integrally connect the first sub-housing and the second sub-housing, merging them into a unified structure that provides electromagnetic interference protection. This integration reduces the number of separate components and assembly steps, thereby reducing manufacturing cost while maintaining the required shielding effectiveness.
3Reliability
If the housing is designed as two separate sub housings, then electromagnetic interference protection is achieved, but assembly difficulty increases
Solution Approach 1:
The first sub-housing and the second sub-housing are nested together through the shield connection member, with the Ethernet signal terminal sub-housing positioned within or adjacent to the power supply terminal sub-housing. This nested arrangement allows for simplified assembly where components can be sequentially installed without requiring complex alignment procedures.

AI summary
A connector housing comprises an inner housing including a rear housing, and a first sub housing and a second sub housing each formed integrally with the rear housing. The first sub housing is sized to accommodate a first cable assembly, and includes a rear end connected to a front side of the rear housing. The second sub housing is sized to accommodate a second cable assembly and a third cable assembly. A rear end of the second sub housing is connected to the front side of the rear housing. The first sub housing and the second sub housing are arranged side by side.
