Solution Overview

Problem

Existing wire end connectors face challenges in reliability and stability during detachment from electronic equipment slot structures, often experiencing uneven force distribution that can lead to latch deformation and instability.

Innovation Solution

A wire end connector design featuring a base with a bridge structure, an elastic fastener with latches and a connecting rod, and a pulling tab with varying widths, where the first width at the tab hole is 50%-100% of the distance between latches, ensuring even force application and preventing latch deformation during detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional wire end connector is used for detachment, then the connector can be removed from the slot structure, but uneven force distribution occurs causing latch deformation and reduced reliability

Engineering Contradiction:
Improvedetachment reliabilityVSAvoidlatch stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The pulling tab is designed with non-uniform width where the first width at the tab hole portion is larger than the second width at the tab channel. This local variation in geometry concentrates the detachment force through the connecting rod to both latches simultaneously, ensuring even force distribution and preventing latch deformation during removal from the slot structure.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If the pulling tab has uniform width, then the structure is simple, but force distribution during detachment is uneven causing latch deformation

Engineering Contradiction:
Improvetab structure simplicityVSAvoiddetachment reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The pulling tab incorporates a localized width variation with a first width at the tab hole portion and a second width at the tab channel, where the first width is larger. This design maintains overall structural simplicity while introducing the specific geometric feature needed to distribute detachment forces evenly to both latches through the connecting rod.

Inventive Principle:
Principle #3Local quality

3Reliability

If the first width of the pulling tab is made very large, then force distribution to latches is improved, but the tab channel width requirement increases device complexity

Engineering Contradiction:
Improveforce distribution uniformityVSAvoidtab channel dimensions
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The design optimizes the width parameters of the pulling tab by establishing a specific relationship between the first width at the tab hole portion and the second width at the tab channel. The first width is configured to be within 50%-100% of the distance between the two latches, providing sufficient force distribution while maintaining reasonable tab channel dimensions and avoiding excessive device complexity.

AI summary

A wire end connector includes a base, an elastic fastener and a pulling tab. The base has an upper surface and a bridge structure disposed on the upper surface. The bridge structure and the upper surface define a tab channel therebetween. The elastic fastener includes two latches and a connecting rod connected between the latches. The latches are connected with the upper surface. The connecting rod has a tab hole portion. The pulling tab wraps around the tab hole portion of the connecting rod and extends outwards through the tab channel. A first width of the pulling tab at the tab hole portion is larger than a second width of the pulling tab at the tab channel.
