Snap-Release Plug Connector Structure for Stable Cable Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable plugs are prone to being pulled out of socket connectors due to lack of supporting structures, leading to potential damage and signal disruption, especially as they become smaller and more compact.
Innovation Solution
An electrical plug connector with a sliding seat, draw belt, and buckle assembly that includes a pivotally connected buckle assembly with support arms and spring leaves, allowing for secure engagement and easy release through pressing or pulling mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cable plug is made smaller and more compact, then the device size is reduced, but the plug becomes easier to pull out and more prone to damage
Solution Approach 1:
The connector is divided into distinct functional components: a plug connector with holder base, a sliding seat with elastic portions, a buckle assembly with support arms and hook portions, and a draw belt. This segmentation allows each component to perform its specific function while working together to provide both compact size and reliable connection through the interlocking mechanism of the buckle assembly
Solution Approach 2:
The connector employs dynamic elements including the sliding seat that can move relative to the holder base, elastic portions that deform under stress, and a buckle assembly that can pivot and lock into position. These dynamic features enable the compact connector to maintain reliable connection through adaptive mechanical responses to insertion and extraction forces
2Device complexity
If no supporting or fixing structure is provided for the plug, then the device complexity is reduced, but the plug is easily pulled out causing signal disruption
Solution Approach 1:
The connector features self-locking and self-releasing mechanisms that operate automatically. The elastic portions self-deform to engage and disengage the hook portions, and the draw belt provides automatic locking when pulled, eliminating the need for external supporting structures while maintaining connection stability
Solution Approach 2:
The buckle assembly acts as an intermediary mechanism between the plug connector and socket connector, providing the necessary supporting and fixing functions. The support arms with hook portions mediate the connection, allowing the plug to be securely held while enabling easy release through the draw belt or pressing action
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
Ensures stable connection and easy disconnection of the plug connector from the socket connector, preventing damage and maintaining signal integrity.
Implementation Method 1
when the draw belt is driven to pull the sliding seat, the at least one elastic portion elastically deforms and also drives the hook portions of the two support arms to elastically deflect downward from the perforations
Implementation Method 2
when the pressing surface is pressed, the supporting spring leaves are elastically deformed and the hook portions of the two support arms are shifted downward by a distance from the perforations
Data Source
AI summary
The invention discloses an electrical plug connector snap release structure, which includes a plug connector, a sliding seat, a draw belt and a buckle assembly, and a matching electrical socket connector. When the plug connector is docked with the socket connector, each supporting spring leaf of the buckle assembly supports down to the holder base of the plug connector, so that the support arms of the buckle assembly force the hook portions thereof to hook in the respective hook holes of the socket connector. When pressing the pressing surface of the buckle assembly or when the draw belt is driven to pull the sliding seat, the supporting spring leaves are elastically deformed and the hook portions are disengaged from the hook holes, allowing the plug connector to be easily disconnected from the socket connector.
