Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receptacle and plug connectors with metallic shields tend to loosen due to repeated mating, leading to insecure attachment.
Innovation Solution
The design incorporates a metallic shield with bending sections and barbed structures that are inserted into retaining recesses, and a receptacle connector with offset bending sections and barbed structures, ensuring stable and secure attachment during mating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a metallic shield is attached to the elongated housing using simple attachment methods, then the device complexity is reduced, but the attachment reliability deteriorates due to loosening from repeated mating
Solution Approach 1:
The bending section is designed to be deformable, transitioning from a straight configuration during assembly to a bent configuration that engages with the retaining recess. This dynamic deformation allows the shield to securely lock onto the housing, preventing loosening from repeated mating while maintaining a relatively simple overall structure.
Solution Approach 2:
The attachment mechanism utilizes changes in the physical state of the bending section, specifically its shape and position. By controlling the deformation parameters of the bending section during assembly, the shield achieves a secure fit within the retaining recess, ensuring reliable attachment that withstands repeated mating operations.
2Reliability
If the bending section is designed with offset free end embedded in the end tower, then the attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The shield structure is segmented into distinct functional sections: the main body, the bending section with offset free end, and the engagement portion that interfaces with the retaining recess. This segmentation allows each part to perform its specific function optimally, with the offset free end providing enhanced anchoring in the end tower while keeping the overall design manageable.
Solution Approach 2:
The offset free end of the bending section acts as an intermediary element that bridges the shield and the end tower. By embedding this intermediate structure into the end tower, a secure mechanical connection is established, enhancing attachment reliability while distributing the structural complexity across multiple coordinated components.

AI summary
An electrical assembly is composed of a receptacle connector and a plug connector adapted to be mated with each other. The plug connector includes an elongated insulative housing forming a receiving space rearwardly recessed from a front mating face thereof with a pair of forwardly extending guiding posts respectively located at two opposite longitudinal ends of said receiving space in the longitudinal direction. A plurality of contacts are disposed in the housing with corresponding contacting sections exposed in the receiving space. A metallic shield is rearwardly assembled upon the housing from a front side of the housing with a pair of bending sections each inserted into the corresponding retaining recess which is terminated behind the front mating face in the front-to-back direction.
