Segmented Electrical Connector Housing for Compact Module Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies have a large overall size due to the design of the insulating housing, which increases the size in the front-to-rear direction and limits compactness.
Innovation Solution
The electrical connector assembly features an insulating housing composed of a front housing and a rear housing, with the rear housing extending downward to surround the terminal modules in three directions, thereby reducing the size of the insulating housing in the front-to-rear direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insulating housing is designed to surround terminal modules completely in all directions, then the terminal modules are well protected, but the size of the insulating housing in the front-to-rear direction increases
Solution Approach 1:
The insulating housing is divided into two separate parts: a front housing and a rear housing. The front housing includes a front top wall and front side walls, while the rear housing includes a rear top wall and rear side walls. These two housings are assembled together to form the complete insulating housing, providing comprehensive protection for the terminal modules while maintaining a compact front-to-rear dimension.
Solution Approach 2:
The rear housing's top wall and side walls extend downward to surround the terminal modules from three directions (top, left, right), rather than extending in the front-to-rear direction. This dimensional approach provides protection in the vertical and lateral directions while keeping the front-to-rear length compact.
2Device complexity
If the insulating housing is designed as a single integrated piece, then the structure is simple, but it is difficult to form and assemble
Solution Approach 1:
The insulating housing is segmented into a front housing and a rear housing that can be manufactured separately and then assembled together. This segmentation makes the molding process easier for each individual housing component while still providing a complete protective structure when assembled.
Solution Approach 2:
The front housing and rear housing are assembled together to form the complete insulating housing. The front housing includes front top wall and side walls, while the rear housing includes rear top wall and side walls that extend downward. When assembled, these two parts merge to provide comprehensive protection for the terminal modules.
