Shield Connector Resin Structure for Finger Touch Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shield connectors require a separate resin cover and increased components and assembly time to prevent finger touch, leading to enlargement and complexity.
Innovation Solution
A shield connector design with a terminal, shield shell, filling resin portion, and integrated finger touch preventing resin portion that projects from the terminal tip, eliminating the need for a separate cover and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate resin cover is mounted on the terminal to prevent finger touch, then finger touch prevention is achieved, but the number of components increases and assembling man-hours increase
Solution Approach 1:
The patent merges the finger touch preventing function with the filling resin portion by integrating a projecting structure into the resin that fills the shield shell. This eliminates the need for a separate resin cover, reducing component count while maintaining finger touch prevention capability.
2Reliability
If a separate resin cover is mounted on the terminal to prevent finger touch, then finger touch prevention is achieved, but assembling man-hours increase
Solution Approach 1:
The finger touch preventing structure is integrated into the filling resin portion, allowing both the filling and finger touch prevention functions to be achieved in a single assembly step, thereby reducing assembling man-hours.
3Reliability
If the shield shell is enlarged to prevent finger approach, then finger touch prevention is achieved, but the entire shield connector enlarges
Solution Approach 1:
Instead of preventing finger approach from the outside by enlarging the shield shell, the patent projects the filling resin portion outward to create a barrier that stops finger touch at a different dimensional approach, maintaining compact shield shell dimensions.
4Reliability
If the shield shell is enlarged to prevent finger approach, then finger touch prevention is achieved, but the entire shield connector enlarges
Solution Approach 1:
The patent combines the shield shell structure with the finger touch preventing structure by integrating the projecting resin portion into the filling resin, eliminating the need for separate enlargement of the shield shell and reducing structural complexity.

AI summary
A shield connector is provided with a terminal including a connecting portion to be connected to a mating terminal on a tip side and a fixing portion on a base end side, a shield shell including a tubular receptacle for surrounding the connecting portion of the terminal and a holding tube portion for surrounding the fixing portion of the terminal, a filling resin portion for integrally fixing the fixing portion of the terminal to the holding tube portion of the shield shell by filling between facing surfaces and of the fixing portion of the terminal and the holding tube portion of the shield shell, and a finger touch preventing resin portion integrated with the filling resin portion and projecting from a tip surface of the connecting portion of the terminal.
