Conductive Shell Noise Shielding for Electrical Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors fail to reliably prevent noise leakage from substrate connections and contamination of noise into signal transmission lines due to exposed substrate connections that are part of signal transmission lines.
Innovation Solution
An electrical connector design featuring a conductive shell with an upper plate, side plates, and a back plate connected to the ground electrode, surrounding the substrate connections to immediately pass noise currents to ground, and locking members to secure the connection object, ensuring effective noise shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If substrate connections are exposed to the outside, then ease of connection is improved, but noise leakage and noise contamination increase
Solution Approach 1:
A conductive shell comprising an upper plate, side plates, and a back plate is employed to cover and surround the substrate connections. This shell structure effectively blocks noise from leaking outward and prevents external noise contamination while maintaining connection functionality through the housing's insertion opening.
Solution Approach 2:
The conductive shell is connected to a ground electrode, creating a disposable noise dissipation path. Noise currents are immediately directed to ground through this dedicated path, effectively neutralizing harmful noise effects without requiring complex active shielding systems.
2Object-affected harmful factors
If a conductive shell surrounds substrate connections, then noise shielding is improved, but device complexity increases
Solution Approach 1:
The conductive shell is segmented into three distinct plates: an upper plate covering the top, side plates blocking the sides, and a back plate covering the rear. This segmentation allows each plate to be independently formed and positioned, simplifying manufacturing while achieving comprehensive noise shielding coverage around the substrate connections.
Solution Approach 2:
The conductive shell structure serves multiple functions simultaneously: it acts as a noise shield, provides structural support within the housing, and creates a defined insertion opening for connection objects. This multi-functionality reduces the need for additional separate components, thereby managing device complexity.
3Reliability
If locking members are added to secure connection objects, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The locking members are integrated directly into the housing structure, merging the locking function with the existing housing component. This integration eliminates the need for separate locking mechanisms while ensuring reliable electrical and mechanical connection between the connector and connection object through the insertion opening.

Function Achieved in This Case
The design effectively prevents noise leakage from the substrate connections to the outside and contamination from the outside into the substrate connections, ensuring reliable signal transmission with reduced noise interference.
Implementation Method 1
a conductive shell that is connected to a ground electrode of the substrate and that comes into contact with a ground member of the connection object... a current component caused by noise trapped by the upper plate, the side plates, and the back plate can be immediately passed through the ground electrode

AI summary
Plural contacts include other ends on which first substrate connections that are connected to the signal electrodes of a substrate are formed. A shell includes an upper plate that covers the whole of the plural contacts on the substrate. Side plates block both ends of the first substrate connections in an array direction (x-axis direction) between the upper plate and the substrate and include edges which face the substrate and on which second substrate connections connected to the ground electrode of the substrate are formed. A back plate blocks the fronts of the first substrate connections with respect to contactors between the upper plate and the substrate and includes an edge which faces the substrate and on which third substrate connections connected to the ground electrode of the substrate are formed.
