Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional connectors with triangular buckles for locking and unlocking lack a pre-ejection function, making it inconvenient to swiftly and effectively separate connectors, especially when the rotation direction is incorrect, limiting bi-directional unlocking capabilities.

Innovation Solution

A connector design incorporating an insulated body, inner and outer shells, a fastener with snap bodies, an ejector with slope surfaces, and elastic elements that allow for rotational pre-ejection by moving push blocks to push the ejector forward, enabling swift separation of connectors when rotated clockwise or counterclockwise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional connectors use triangular buckles for locking and unlocking, then the connectors can be stably connected, but the connectors cannot be swiftly and effectively separated

Engineering Contradiction:

Improveconnection stabilityVSAvoidseparation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The ejector is pre-positioned within the outer shell and the push blocks are pre-arranged to interact with the ejector's slope surfaces. When the outer shell is rotated, the push blocks automatically engage the ejector and drive it forward to perform the separation action, eliminating the need for manual ejection operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connector transitions from a static locked state to a dynamic ejection state through rotation of the outer shell. The rotational motion is converted into linear motion of the ejector via the slope surfaces, enabling swift and effective separation of the connectors.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If conventional connectors allow bi-directional unlocking by rotation, then the unlocking operation is convenient, but the connectors still lack pre-ejection function for swift separation

Engineering Contradiction:

Improveunlocking convenienceVSAvoidseparation efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The invention merges the unlocking function with the pre-ejection function into a single integrated mechanism. The same rotational motion of the outer shell that enables bi-directional unlocking also activates the ejector to perform pre-ejection, combining two functions into one operational action.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The outer shell serves multiple functions: it provides structural protection, enables bi-directional unlocking through rotation, and activates the pre-ejection mechanism. The push blocks and ejector system are designed to work with the rotational motion for both unlocking and ejection purposes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If the outer shell is rotated to drive push blocks and ejector for pre-ejection, then swift and effective separation is achieved, but the device complexity increases

Engineering Contradiction:

Improveseparation speedVSAvoidstructure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The ejection mechanism is segmented into distinct functional components: the ejector body with slope surfaces, multiple push blocks positioned at intervals, and elastic elements. This segmentation allows each component to perform its specific function while maintaining overall system simplicity and ease of manufacturing.

Inventive Principle:

Principle #1Segmentation

AI summary

A connector with a direct locking and a rotational pre-ejection function is provided. The connector includes an insulated body, a plurality of terminals, an inner shell, an outer shell, a fastener, an ejector, a first elastic element, and a second elastic element. A plurality of push blocks are disposed in the outer shell, the ejector has a plurality of slope surfaces, and the push blocks are in contact with the slope surfaces, respectively. When the connector and a mating connector are inserted into each other, snap bodies of the fastener and fastener bodies of the mating connector can be snapped into each other to be directly locked. When the connector and the mating connector are to be separated from each other, the outer shell can be rotated to cause the snap bodies to disengage and to cause the push blocks to rotate while in contact with the sloped surfaces to effect ejector rods to move forwardly to eject the mating connector.
