Cable End Connector Latch Anchoring Against Impact Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable end connectors suffer from unreliable connections due to the latch detaching under impact, compromising the connection's reliability.
Innovation Solution
A cable end connector design featuring a latch connected via a connecting shaft to a base, allowing it to remain firmly attached even under impact, using a pull-string to facilitate disconnection when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a deformable buckling piece (latch) is used to enable unlocking when pressed, then the connector achieves ease of operation for disconnection, but under impact the limiting arms fail to prevent the hook portions from disengaging from the clamping grooves, causing the latch to detach and compromising connection reliability
Solution Approach 1:
The latch is divided into functionally independent parts: the body portion with hooks for connecting to the board end connector, and the bent portion that independently engages with the base through the connecting shaft. This segmentation ensures that the connection function and the anchoring function are separated, so that even if the hooks disengage under impact, the latch remains anchored to the base and cannot detach accidentally.
Solution Approach 2:
The bent portion of the latch is preliminarily anchored to the base through the connecting shaft before any impact or disconnection event occurs. This preliminary anchoring action ensures that the latch is firmly connected to the base in advance, preventing accidental detachment under impact while still allowing intentional disconnection through the designed unlocking mechanism.
2Ease of operation
If the latch is made deformable to allow unlocking when pressed, then the connector enables easy disconnection, but the deformability causes the latch to potentially disconnect from the base under accidental impact
Solution Approach 1:
The latch is segmented into a body portion that remains deformable for unlocking and a bent portion that is stabilized by the connecting shaft. This segmentation allows the body portion to maintain its deformability for easy unlocking while the bent portion's connection to the base provides stability, preventing the entire latch from detaching under impact.
Solution Approach 2:
The connecting shaft acts as an intermediary element between the latch and the base. It mediates the relationship by providing a stable anchoring point for the bent portion while allowing the body portion to remain deformable. This intermediary connection enables the latch to be both stable (anchored to base) and deformable (body portion can still move for unlocking).

AI summary
Disclosed is a cable end connector. The cable end connector includes: a base; a circuit board fixedly disposed in the base; a cable connected to the circuit board; and a latch fixedly disposed in a mounting groove of the base. The latch has a body portion and a bent portion formed by bending downwards from a rear edge of the body portion, the bent portion can abut against the base, and the body portion has a plurality of hooks extending forwards. The cable end connector further includes a connecting shaft, a mounting space for the connecting shaft to penetrate through is formed between the body portion and the bent portion, and the connecting shaft penetrates through the mounting space and is inserted into a connecting hole of the base, which can prevent the latch from falling off and has better connection reliability.
