Compact Connector Locking Layout for Single-Motion Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connector locking mechanisms are bulky due to the arrangement of locking and unlocking members in the front-back direction, increasing the total length of the connector assembly.
Innovation Solution
The connector locking mechanism is redesigned with locking and unlocking members positioned orthogonally, allowing for a compact design by overlapping them in the vertical direction and enabling unlocking with a single motion of pulling the unlocking member backward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking member and unlocking member are arranged in the front-back direction (linear arrangement), then the locking function is achieved, but the total length of the connector assembly in the mating direction increases
Solution Approach 1:
The patent transitions from a linear front-back arrangement to a spatial arrangement where the locking member and unlocking member are positioned at different locations in the vertical direction (up-down direction). The unlocking member is located below the locking member, creating a two-dimensional spatial configuration that reduces the connector assembly's length in the mating direction while preserving the locking function through the engagement relationship between the locking shaped portion and unlocking shaped portion
2Reliability
If the locking member and unlocking member are positioned at separated locations, then the locking mechanism functions properly, but the operational complexity and number of movements required for unlocking increase
Solution Approach 1:
The patent combines the locking and unlocking functions into a single integrated mechanism. The unlocking member is designed to simultaneously perform both locking engagement and unlocking release through one continuous motion. When the unlocking member moves in the up-down direction, it first engages with the locking shaped portion to lock, and then by continuing the same motion direction, it disengages to unlock, eliminating the need for separate locking and unlocking operations

AI summary
A connector locking mechanism comprises a first connector includes including a cantilevered locking member extending in a first direction, and having a first locking shaped portion, and a first unlocking portion having an inclined surface and formed between a fixed end of the locking member and the first locking shaped portion; and a second connector including an unlocking member held to be movable in the first direction and the second direction, a second locking shaped portion to be engaged with the first locking shaped portion, and a second unlocking portion having an inclined surface to be brought into contact with the inclined surface of the first unlocking portion when the second connector is mated with or withdrawn from the first connector.
