Shielded Cable End Connector with Metal Orientation Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing end connectors for vehicles, particularly those connecting shielded cables to lighting equipment, face challenges with long-lasting connections under high vibration conditions and electromagnetic radiation emission, due to the use of plastic materials that lose resilience over time and require complex fastening mechanisms, increasing size and weight.
Innovation Solution
An end connector design featuring an orientation component with dual mechanical functions, made from high mechanical resistance materials like metal, which secures the cable connection and sets its direction, while also providing reliable fastening means to prevent disconnection, allowing for a downsized connector body with improved dielectric properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the connector housing is made of plastic material, then the connector size and weight are reduced, but the connection reliability deteriorates over time due to loss of resilience properties
Solution Approach 1:
The connector is divided into two separate components: a plastic connector housing and a metal orientation component. Each component performs specific functions, with the metal component providing mechanical fastening and the plastic housing providing electrical insulation and structural support. This segmentation allows optimization of each material for its specific purpose.
Solution Approach 2:
The orientation component merges multiple functions into a single element: cable orientation guidance, mechanical fastening to the connector, and secure attachment to the equipment. This integration reduces the number of separate parts while improving connection reliability through the use of metal material.
2Reliability
If specialized fastening means are provided on the connector body, then the mechanical connection reliability is improved, but the connector complexity and size increase
Solution Approach 1:
The orientation component serves multiple functions simultaneously: it orients the cable, provides mechanical fastening to the connector body, and secures the connection to the equipment. This multi-functionality reduces the need for separate specialized fastening mechanisms while maintaining high connection reliability.
3Volume of stationary object
If the connector size is reduced, then the volume occupied by the connection is minimized, but the fastening means become less effective under high vibration conditions
Solution Approach 1:
The connector assembly combines plastic and metal materials, each contributing their superior properties. The metal orientation component provides vibration resistance and mechanical strength, while the plastic housing provides insulation and structural form. This composite approach maintains small overall size while ensuring vibration-resistant fastening.
