Metal Shell Anti-Displacement Structure for Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connectors with metal shells often detach from insulating bases due to large forces during plugging and unplugging, leading to structural instability and potential damage.
Innovation Solution
A miniaturized electrical connector design featuring a metal shell with a U-shaped cross section, including upper and lower fixing parts and positioning parts, which securely assemble onto an insulating base, preventing upward, downward, forward, and backward motion, thereby enhancing stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the metal shell is designed with fixing parts and positioning parts, then the assembly stability is improved, but the device complexity increases
Solution Approach 1:
The metal shell is segmented into multiple functional parts: fixing parts (upper and lower) and positioning parts (first and second), each performing a specific constraint function. This segmentation allows the complex stabilization task to be divided into manageable components, where each part contributes to preventing displacement in specific directions, thereby achieving high assembly stability through modular design.
Solution Approach 2:
The invention addresses multi-directional displacement issues by introducing fixing parts and positioning parts that operate in different spatial dimensions. The fixing parts constrain vertical movement (upward/downward), while the positioning parts constrain horizontal movement (forward/backward), effectively stabilizing the assembly in three-dimensional space through dimensional decomposition of constraint functions.
2Volume of moving object
If the connector dimensions are kept compact, then the portability is improved, but the assembly stability deteriorates
Solution Approach 1:
The fixing parts and positioning parts are nested within the compact metal shell structure, with each component integrated into the overall housing without requiring external attachments or excessive space. The upper and lower fixing parts are positioned within the shell's vertical boundaries, while the positioning parts are integrated into the side walls, achieving multi-directional constraint within a minimized volume through nested spatial arrangement.

AI summary
A connector with a metal shell having an anti-displacement structure. The connector comprises an insulating base, a plurality of metal terminals and a metal shell. A side arm of the metal shell has a first upper fixing part, a first lower fixing part and a first positioning part. The first upper fixing part abuts an upper surface of the insulating base, and the first lower fixing part abuts a lower surface of the insulating base. The first positioning part is combined with a second positioning part on a side face of the insulating base. In this way, the insulating base is restrained from moving upward, downward, leftward or rightward relative to the metal shell, thereby effectively improving the assembly stability of the connector.
