Solution Overview

Problem

Existing shielded connector assemblies face issues with metal powder intrusion into terminal contact portions due to friction, leading to short circuits and arcs, and have difficulties with easy assembly and disassembly, space utilization, and bolt-related wear and tear.

Innovation Solution

An elastic member with a plate spring and fixing member is installed outside the terminal contact portion, allowing for easy assembly and disassembly, preventing metal powder intrusion, and optimizing space usage by providing a secure and stable electrical connection between male and female shielded connectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a bolt is used to connect the male shielded connector to the female shielded connector, then the connection is secure, but the product size increases and assembly/disassembly becomes difficult

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The invention extracts the bolt from the connector assembly entirely, replacing it with an elastic member that provides both connection and electrical contact functions. The elastic member is integrated into the connector housing, eliminating the need for separate fastening components and simplifying the assembly structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The elastic member serves multiple functions simultaneously: it acts as both a mechanical fastener (replacing the bolt) and an electrical contact element. This multi-functional design reduces the number of components needed and simplifies the overall connector structure while maintaining secure connection.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Strength

If a bolt is used to connect the male shielded connector to the female shielded connector, then the connection is secure, but wear and tear occurs under vehicle jolting conditions

Engineering Contradiction:
Improveconnection strengthVSAvoidconnection reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The elastic member is designed to be deformable, allowing it to dynamically adjust to vibrations and shocks from vehicle jolting. The elasticity enables the connection to absorb mechanical stress without permanent deformation or loosening, maintaining reliable electrical contact under varying conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic nature of the member provides beforehand cushioning against vibrations and shocks. The elastic deformation capacity allows the connection to absorb mechanical energy from vehicle jolting before damage can occur, preventing wear and tear on the electrical contact surfaces.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Strength

If a bolt is used to connect the male shielded connector to the female shielded connector, then the connection is secure, but metal powder intrudes into the terminal contact portion causing short circuit

Engineering Contradiction:
Improveconnection strengthVSAvoidmetal powder intrusion
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the bolt that causes metal powder generation and removes it from the system. By replacing the bolt with a boltless elastic member design, the source of metal powder intrusion is eliminated, preventing short circuits in the terminal contact portion.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The elastic member is designed to be replaceable and can be easily disposed of when worn. This allows for maintenance without complex tooling, and the simple elastic structure generates minimal wear debris compared to threaded bolt connections.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Device complexity

If the shielded connector assembly is arranged linearly, then the structure is simple, but the installation space is insufficient

Engineering Contradiction:
Improvestructural complexityVSAvoidinstallation space
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The connector assembly transitions from a linear arrangement to a three-dimensional compact configuration. The elastic member enables vertical stacking and angular positioning of connector components, utilizing space in multiple dimensions rather than extending linearly, thereby reducing the overall installation footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Disclosure relates to an elastic member mounted in a securing part formed at a male shielded connector or a female shielded connector and configured to establish an electrical connection between the male shielded connector and the female shielded connector when the male shielded connector and the female shielded connector are assembled. The elastic member includes a plate spring having a predetermined length; an elastic piece being elastically deformable and formed by bending a portion of one or both sides of the plate spring in the lengthwise direction of the plate spring; and a fixing member formed on the plate spring and configured to prevent the elastic member from separating from the male shielded connector or the female shielded connector when the male shielded connector and the female shielded connector are disassembled.
