Dual Plug Cable Connector Assembly for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors are prone to loosening due to external forces, leading to unstable data transmission when plugged into multiple interfaces, causing interruptions.
Innovation Solution
A cable connector assembly design featuring a first plug connected to a printed circuit board via a first connector, with a second connector assembled onto the first connector to provide mechanical stability by not being electrically connected to a second port, and a method involving insert molding of casings to secure the assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single plug is used to connect to one interface, then the connection structure is simple, but the connection is easily loosened by external forces
Solution Approach 1:
The patent combines two connectors into a single integrated assembly where the second connector is assembled onto the first connector. This merging allows both connectors to work together as a unified structure, providing mutual support and stabilization. The first connector maintains electrical connection while the second connector provides additional mechanical support, preventing loosening without significantly increasing overall structural complexity.
Solution Approach 2:
The first connector serves dual functions: it provides electrical connection through its plug while simultaneously serving as a mounting structure for the second connector. The first connector body acts as both an electrical interface component and a mechanical support structure, reducing the need for additional separate support components and maintaining structural simplicity.
2Reliability
If a second connector is assembled onto the first connector, then the connection stability is improved, but the device complexity increases
Solution Approach 1:
The second connector is nested onto the first connector, with the second connector's outer casing fitting over the first connector's outer casing. This nesting arrangement allows the second connector to provide additional mechanical support and stabilization while utilizing the space and structure already provided by the first connector. The nested configuration minimizes the increase in overall assembly complexity compared to a side-by-side or separate mounting arrangement.
