Solution Overview

Problem

Existing electrical connectors lack a stable locking mechanism to prevent disengagement from adapter connectors due to weak locking forces.

Innovation Solution

An electrical connector design featuring a shaft lever with dual threaded regions that screw into the adapter connector, enhancing stability through threaded engagement and optional use of a locking member and guide rail for additional locking, ensuring secure attachment and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fastener is used as the locking structure, then the electrical connector can be connected to the adapter connector, but the locking force is weak and the connection is easily released

Engineering Contradiction:
Improvelocking stabilityVSAvoidlocking force
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The patent changes the locking mechanism from a simple fastener to a threaded connection system. The shaft lever incorporates threads that engage with corresponding threaded holes in the adapter connector, transforming the locking mechanism from relying solely on friction and simple mechanical interference to utilizing threaded engagement which provides superior locking force and resistance to loosening.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The shaft lever is divided into functional segments including a first threaded region for connection to the shell and a second threaded region for engagement with the adapter connector. This segmentation allows each region to perform its specific function optimally, with the threaded portions providing robust mechanical interlocking.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a threaded connection is used to enhance locking stability, then the locking force is improved, but the device complexity increases

Engineering Contradiction:
Improvelocking stabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the locking function and the connection function into a single integrated shaft lever component. The shaft lever simultaneously provides structural support, electrical connection pathway, and threaded locking engagement. This consolidation eliminates the need for separate locking mechanisms, fasteners, or additional locking components, thereby reducing overall device complexity while maintaining enhanced locking stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shaft lever serves multiple functions: it provides structural support for the electrical connection portion, acts as a mechanical locking element through its threaded regions, and facilitates both assembly and disassembly of the connector. This multi-functionality reduces the number of components needed and simplifies the overall device structure.

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

AI summary

An electrical connector is provided, including a shell, an electrical connection portion, and a shaft lever. The electrical connection portion is arranged on the shell. The shaft lever is provided with a first threaded region and a second threaded region. The first threaded region has the same thread direction as the second threaded region, and is in threaded connection with the shell. The second threaded region is configured to be screwed into a hole of the adapter connector to be fastened with an inner wall of the adapter connector. The electrical connector can be fastened to the adapter connector in a more stable locking manner.
