Cable Connector Assembly With Integrated Fixing Block Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable connector assemblies in existing technologies are prone to loosening or failure of soldering/welding connections due to external forces, leading to structural unreliability.
Innovation Solution
A cable connector assembly design where a fixing block secures cables to a circuit board, ensuring the core of the cable corresponds to the mounting portion of a conductive terminal, with electrical connections protected by integral assembly and fastening devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cables are connected to electrical connector first and then mounted to circuit board, then assembly sequence is simple, but soldering/welding connections loosen or fall off under external forces
Solution Approach 1:
The fixing block is pre-integrated with the electrical connector body, and cables are pre-positioned within the connector assembly before mounting to the circuit board. This preliminary integration ensures that cables are securely held in place during the mounting process and under subsequent external forces, preventing soldering/welding connections from loosening or falling off.
Solution Approach 2:
The fixing block and electrical connector body are merged into an integral structure, and the cable assembly is combined with the connector assembly before circuit board mounting. This merging creates a unified structure where the fixing block, connector, and cables work together as a single unit, improving both structural reliability and assembly efficiency.
2Stability of the object's composition
If cables are secured with separate fixing components, then cable positioning is improved, but device complexity increases
Solution Approach 1:
The fixing block is merged with the electrical connector body to form an integral structure, eliminating the need for separate fixing components. This integration maintains stable cable positioning while reducing the total number of parts and simplifying the overall device structure.
Solution Approach 2:
The fixing block serves multiple functions: it positions cables, secures them to the connector body, and provides structural support for the entire assembly. This multi-functionality reduces the need for additional specialized components, thereby reducing device complexity while maintaining cable stability.
