Solution Overview

Problem

Conventional connector sets restrict slide movement and fail to enhance the pullout strength of the first housing from the second housing when fitted together.

Innovation Solution

A connector set design that includes a slide member with an engaging part locked to a locked part on the other housing, allowing the slide member to slide between positions and enhancing the locking mechanism between the first and second housings, thereby increasing the pullout strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a slide member with engaging part locked to locked part is added to restrict slide movement, then the locking mechanism is enhanced, but the pullout strength of the first housing from the second housing is not improved

Engineering Contradiction:
Improvelocking mechanism stabilityVSAvoidpullout strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The invention combines the lever part and the engaging part into an integrated structure where the lever part serves dual functions: it acts as both the locking lever and the engaging part that locks to the locked part on the other housing. This merging of functions creates a more robust locking mechanism that simultaneously provides slide movement restriction and enhanced pullout strength.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention introduces a new dimensional aspect to the locking mechanism by forming the lever part continuously on the housing main body, creating a multi-dimensional engagement structure. The lever part extends in multiple directions to provide both the sliding restriction function and the pullout strength enhancement through its continuous integration with the housing main body and engagement with the locked part.

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

2Ease of operation

If the lever part is made movable relative to the housing main body to allow slide movement, then the slide member can move between positions, but the pullout strength is reduced

Engineering Contradiction:
Improveslide movement capabilityVSAvoidpullout strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The invention implements a dynamic locking mechanism where the lever part can move relative to the housing main body to enable slide movement between first and second positions. The lever part's movability is controlled through its engagement with the locked part, allowing it to remain stationary during normal operation while permitting controlled movement when needed. This dynamic design maintains pullout strength while enabling operational flexibility.

AI summary

A connector set includes: a first connector having a first housing; a second connector having a second housing; and a slide member slidably held in one of the housing. An engaging part is formed on the slide member, the engaging part being locked to a locked part formed on the other housing to restrict the sliding of the slide member to the first position when the slide member is slid to the second position. The locked part is formed on the housing main body of the other housing.
