Split Connector Lock Arms Resilient Deformation Oblique Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split connectors fail to reliably engage two lock arms and two lock portions when the auxiliary housing is inserted obliquely, leading to incomplete locking.
Innovation Solution
Incorporating resiliently deformable lock arms and locks with resistance arms and resistance generating portions that contact each other at normal angles, allowing the lock arms to deform and engage locks when an exceeding force is applied, ensuring proper insertion and locking of the auxiliary housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the auxiliary housing is inserted obliquely into the frame, then insertion is easier, but only one lock arm and one lock may engage while the other remains unengaged, reducing locking reliability
Solution Approach 1:
The resistance generating portion is provided on the auxiliary housing to preemptively counteract the harmful effect of oblique insertion. By designing this resistance mechanism in advance, the system ensures that even if oblique insertion occurs, the auxiliary housing will be corrected to a proper insertion state before locking engages, thereby maintaining both ease of operation and locking reliability
2Reliability
If resistance arms and resistance generating portions contact each other during insertion, then insertion resistance is generated, but this may hinder the auxiliary housing from reaching the proper insertion position
Solution Approach 1:
The resistance arm is designed to be resiliently deformable, allowing it to dynamically adjust during insertion. When the auxiliary housing is properly inserted, the resistance arm deforms to disengage the locking surfaces, reducing insertion resistance and enabling smooth completion of the insertion process while maintaining reliable locking
3Reliability
If the lock arms are made resiliently deformable to engage locks reliably, then locking reliability improves, but insertion resistance increases, potentially hindering proper positioning
Solution Approach 1:
The resistance generating portion on the auxiliary housing provides preliminary resistance during insertion, counteracting the harmful effect of lock arm deformation before the locking engagement occurs. This ensures that the lock arms can be resiliently deformable for reliable locking without excessively hindering the insertion process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures reliable engagement of lock arms and locks, preventing insertion resistance from hindering the auxiliary housing's proper positioning and ensuring swift, secure locking without inclining during insertion.
Implementation Method 1
The resistance arm is deformed resiliently to disengage the locking surfaces by applying an inserting force to the auxiliary housing that exceeds a locking force of the locking surfaces
Implementation Method 2
Two resiliently deformable lock arms are provided in the frame and face the accommodation space
Implementation Method 3
The lock arms and the locks have sliding-contacts that slide in contact with each other with the lock arms resiliently deformed

AI summary
An auxiliary housing (20) inserted into a frame (10) is locked in a retained state by the locking action of resiliently deformable lock arms (13) and locks (21). The lock arms (13) and the locks (21) include locking surfaces (17, 23) that are substantially normal to an inserting direction of the auxiliary housing (20) and come into contact with each other with the lock arms (13) and the locks (21) engaged in an insertion process of the auxiliary housing (20). When an inserting force exceeding a locking force of the locking surfaces (17, 23) is applied to the auxiliary housing (20), the lock arms (13) are resiliently deformed to disengage the locking surfaces (17, 23).
