Connector Latch Member with Side-Extended Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies with latch mechanisms are prone to damage and instability when subjected to large forces, as the region around the latch openings fails to return to its original state effectively.
Innovation Solution
The connector assembly features a latch mechanism with a first opening extending from the middle line of the mating portion to both sides, enlarging the area around the opening and incorporating a projection or rib structure to facilitate easy return to the original state, combined with a pulling member that can release the locking portion from a locking state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional latch member with a small first opening is used, then the device complexity is reduced, but the strength and stability of the latch member deteriorate when subjected to large forces
Solution Approach 1:
The first opening extends not only in the vertical direction but also horizontally to both sides of the mating portion, utilizing multiple dimensions to enlarge the area. This dimensional expansion strengthens the latch member by distributing stress across a larger area while maintaining the simplicity of the overall structure.
Solution Approach 2:
The first opening is integrated with the connecting portion of the latch member, merging the opening structure with the connecting function. This integration allows the opening to serve dual purposes: enabling connection with the post while simultaneously providing structural reinforcement through its extended geometry.
2Reliability
If a latch member with a small first opening is used, then the manufacturing process is simplified, but the reliability of the latch mechanism deteriorates under large forces
Solution Approach 1:
By extending the first opening horizontally in addition to vertically, the design achieves improved reliability through enhanced structural support without significantly complicating the manufacturing process. The extended opening can still be formed using standard stamping or molding techniques.
Solution Approach 2:
The first opening is strategically positioned and shaped to concentrate structural reinforcement where needed - specifically where the latch member connects to the post and where forces are applied. This localized quality enhancement improves reliability without requiring overall structural complexity.
3Area of stationary object
If the first opening is enlarged to both sides of the mating portion, then the area around the opening is increased to strengthen the latch member, but the device complexity increases
Solution Approach 1:
The enlarged first opening is merged with the connecting portion of the latch member, so that the opening itself becomes part of the connecting structure. This merging allows the area to be enlarged for strength without adding separate complex components.
Solution Approach 2:
The first opening serves multiple functions: it provides structural reinforcement through its enlarged area, enables connection with the post, and maintains the latch member's ability to return to its original state. This multi-functionality reduces the need for additional components.

AI summary
A cable connector assembly includes a connector and a cable. The connector includes: a housing including a mating portion and a body portion, a latch mechanism mounted on the housing, and a metal casing enclosing the housing. The body portion includes a receiving slot at a front end thereof and a post projecting upwardly. The latch mechanism includes a latch member received in the receiving slot and a pulling member coupled to the latch member. The latch member includes a locking portion extending beyond the body portion and above the mating portion, a holding portion held on the body portion, and a connecting portion. The connecting portion of the latch member includes a first opening mating with the post. The first opening extends from a middle line of the mating portion sidewardly to both sides of the mating portion.
