Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies fail to achieve full shielding and grounding due to incomplete coverage of the shielding plate and lack of direct connection between the grounding member and the ground shielding structure, making the assembly process complex and inconvenient.
Innovation Solution
A connector assembly with an insulative housing, conductive terminals, a metal shielding plate, and a grounding member that is electrically connected to the metal shielding layer of the cable, ensuring comprehensive shielding and simplified assembly by direct soldering of the cable's core wires to the grounding member and conductive terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grounding member is sleeved at the tail portion of the terminal module in advance and both positioning and soldering are required, then the grounding connection is achieved, but the assembly process becomes complicated and inconvenient
Solution Approach 1:
The grounding member integrates multiple functions into a single component: it serves as both the grounding connection element and the positioning structure. The L-shaped configuration combines the grounding contact portion with the positioning portion that fits into the housing groove, eliminating the need for separate positioning and grounding components, thus simplifying the assembly process while maintaining reliable grounding connection.
Solution Approach 2:
The grounding member's L-shaped structure enables self-positioning and self-alignment during assembly. The positioning portion automatically fits into the groove of the housing, guiding the grounding contact portion into the correct position for soldering with the cable's metal shielding layer, without requiring additional positioning steps or components.
2Device complexity
If the shielding plate does not cover the front and rear directions of the two terminal modules, then the structure is simpler, but the shielding and grounding effect is insufficient
Solution Approach 1:
The grounding member extends in multiple directions to provide comprehensive shielding coverage. The L-shaped configuration allows the grounding contact portion to connect with the cable's metal shielding layer while the positioning portion extends into the housing groove, creating a three-dimensional grounding structure that covers both front and rear directions of the terminal modules, thereby enhancing the shielding and grounding effect without significantly increasing structural complexity.
