Shield Connector Cover Standardization for Lower Part Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shield connectors typically have a large number of components, leading to increased costs.
Innovation Solution
A connector design that allows for the common use of components by using first and second outer conductor covers of the same shape, enabling the same or similar dimensions for outer conductor body portions, and incorporating press-fit projections to ensure stable accommodation of inner conductors, thereby reducing costs and improving connection reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shield connector is designed with separate outer conductor covers for male and female connectors, then connection reliability and shielding performance are improved, but component variety increases and manufacturing cost rises
Solution Approach 1:
The outer conductor cover is designed with universal applicability to serve both male and female connectors. The cover structure includes positioning protrusions and receiving grooves that enable it to function as both a first outer conductor cover and a second outer conductor cover, eliminating the need for separate specialized covers for each connector type.
Solution Approach 2:
The outer conductor cover is divided into functional segments: a positioning protrusion portion that provides positioning functionality, a connecting portion that provides electrical connection, and a covering portion that provides shielding. This segmentation allows a single cover design to fulfill multiple functions required for both male and female connectors.
2Manufacturing precision
If separate outer conductor body portions are used for male and female connectors, then connection precision is improved, but manufacturing cost and component complexity increase
Solution Approach 1:
The outer conductor body portion is designed with universal dimensions and structure that enable it to be used in both male and female connectors. The body portion includes standardized connecting portions and positioning features that ensure precise connection regardless of whether it is used in a male or female connector configuration.
Solution Approach 2:
The invention utilizes parameter standardization where the outer conductor body portion maintains consistent dimensional parameters, material properties, and structural characteristics across both male and female connector applications. This parameter uniformity enables cost-effective manufacturing while maintaining connection precision.

AI summary
The first connector includes a first inner conductor, a first outer conductor, a first outer conductor cover and a first dielectric. The second connector includes a second inner conductor, a second outer conductor, a second outer conductor cover and a second dielectric. The second outer conductor includes a second outer conductor connecting portion overlapping the first outer conductor in a radial direction. The first outer conductor includes a first outer conductor body portion, a first outer conductor connecting portion for covering the outer periphery of the second outer conductor connecting portion and contacting the second outer conductor connecting portion, and a constricted portion reduced in dimensions from the first outer conductor connecting portion to the first outer conductor body portion. The first outer conductor cover and the second outer conductor cover have the same shape.
