Cable Connector Restricting Portions Prevent Shell Rocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable assemblies for high-speed signal transmission lack reliable engagement with complementary connectors due to unsupported shell sides, leading to unstable connections.
Innovation Solution
A cable connector assembly featuring a front housing piece with upwardly extending restricting portions and an engaging portion, along with a locking member, to prevent rocking of the complementary connector shell during mating, ensuring secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the engaging portion alone is used to support the shell, then the structure is simple, but the shell is liable to rotate and engagement is not reliable
Solution Approach 1:
The housing structure is segmented into multiple functional portions: the engaging portion for primary connection and two restricting portions for lateral constraint. This segmentation allows each portion to perform its specific function, preventing shell rotation while maintaining overall structural coherence.
Solution Approach 2:
The restricting portions extend upwardly from the housing in a vertical dimension, creating receiving grooves that constrain the shell laterally. This adds a new dimensional constraint (vertical restriction) to complement the horizontal engagement, preventing rotation without overcomplicating the base structure.
2Stability of the object's composition
If the shell is unsupported on two sides, then the manufacturing is simple, but the shell rotates during engagement
Solution Approach 1:
The housing structure applies local quality by providing support only where needed: the restricting portions are positioned laterally to constrain the shell sides, while the engaging portion handles the primary connection. This localized support prevents rotation without requiring complete circumferential support, maintaining manufacturing simplicity.
Solution Approach 2:
The restricting portions act as intermediary elements between the housing and the shell, providing lateral constraint without directly interfering with the primary engagement function. These intermediaries prevent shell rotation by creating receiving grooves that guide and stabilize the shell during connection.

AI summary
A cable assembly includes a PCB, a rear housing, a front housing assembled with the rear housing and a locking member. The printed circuit board includes a mating end formed with a plurality of first conductive pads and rear end formed with a plurality of second conductive pads. The rear housing is over molded around the rear end of the PCB. The front housing encloses a part of the PCB. The front housing defines a receiving slot and an engaging portion. The locking member is assembled to the engaging portion. The front housing further has two restricting portions extending upwardly from the upper surface thereof, each restricting portion has a supporting portion, an extension portion forwardly extending from a rear end of the supporting portion and spaced from the supporting portion so that a receiving groove is formed between the supporting portion and the extension portion.
