AS-Interface Connector Geometry for Reverse Polarity Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting devices for AS-Interface cables require cumbersome looping or folding to ensure correct polarity during installation, complicating the installation process.
Innovation Solution
A connecting device with a recess that accommodates the AS-Interface cable in two orientations, featuring a protruding element to prevent incorrect polarity by allowing insertion in either configuration without looping, and a wedge-shaped protrusion to deform the cable's shape-encoding protrusion for stable insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connecting device with a fixed recess shape is used to ensure reverse polarity protection, then correct polarity connection is guaranteed, but the cable must be looped or folded during installation which complicates the installation process
Solution Approach 1:
The recess is designed with a deformable protrusion element that can adapt its shape during cable insertion. The protrusion can elastically deform to accommodate the cable's shape-encoding protrusion in either orientation, then returns to its original position to maintain reverse polarity protection. This dynamic adaptability allows simple straight insertion while preserving the polarity protection function.
Solution Approach 2:
The physical state of the protrusion element changes from a rigid fixed shape to a deformable state that can temporarily alter its geometry. The material properties are selected to allow elastic deformation within a specific range, enabling the protrusion to accept cable insertions in multiple orientations while maintaining its polarity-protection function after insertion.
2Ease of operation
If the recess is designed to accept cable in multiple orientations, then installation is simplified, but reverse polarity protection is compromised
Solution Approach 1:
The protrusion element dynamically adjusts its shape during the insertion process. When the cable is inserted in the correct orientation, the deformable protrusion accommodates the cable's shape-encoding protrusion and then maintains a configuration that ensures proper electrical contact. The dynamic behavior allows multi-orientation acceptance while preserving polarity protection through controlled deformation and recovery.

AI summary
A connecting device for providing an electrical connection with an AS-Interface cable having a shape-encoding protrusion includes a housing. At least one recess in the housing has a cross-section to accommodate the cross-section of the AS-Interface cable in at least two configurations. A protruding element laterally protrudes from one side of the recess to form accommodation spaces between the protruding element and the bottom of the recess and between the protruding element and the opening of the recess, respectively. The accommodation spaces are configured to accommodate the shape-encoding protrusion of the AS-Interface cable when fully inserted into the recess.
