Pull-Tab Plug Connector Engagement for Stable Cable Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional socket connectors are inflexible for cable connections, prone to disconnection, and have poor heat dissipation and firmness issues, leading to safety risks and difficulty in separation, especially in narrow spaces.
Innovation Solution
A plug connector design featuring a plug housing, conductive terminals, a spacer, and a pull tab mechanism that allows for secure cable connection via welding or conductive glue, with a connector engagement component for stable engagement and disengagement, and ventilation holes for heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional socket connector is used, then it can be installed on a circuit board with a data connector, but it cannot be assembled with a cable, reducing application flexibility
Solution Approach 1:
The socket connector is designed to accommodate multiple connection types. The plug connector can be connected to either a cable or a circuit board with a data connector, allowing the same socket connector to serve multiple functions and applications, thereby improving adaptability without significantly increasing device complexity
2Reliability
If existing plug connectors are connected to socket connectors, then electrical connection is established, but they are easily disconnected, resulting in circuit breakage and safety accidents
Solution Approach 1:
The engagement component incorporates a dynamic locking mechanism that automatically engages when the plug connector is inserted into the socket connector. The component features movable elements that shift from an unlocked to a locked position, providing automatic securing without requiring additional manual operations, thereby improving both connection stability and engagement firmness
3Ease of operation
If the plug connector is pulled from a narrow space, then separation is needed, but it is difficult to clamp and pull out, and pulling the cable can result in disconnection between cable and conductive terminal
Solution Approach 1:
A dedicated pull component is introduced as an intermediary element between the user and the plug connector. This pull component features an extended structure that can be easily grasped and provides a mechanical advantage for pulling the plug connector out of narrow spaces. The pull component is firmly attached to the plug connector body, ensuring that force is transmitted to the connector rather than the cable, thereby preventing cable-terminal disconnection while improving separation ease
4Strength
If cable and conductive terminal are connected by physical overlapping, then connection is established, but the plug connector size increases and firmness between cable and terminal is poor
Solution Approach 1:
The physical overlapping connection is replaced with a more efficient connection method. The cable is secured to the conductive terminal through a streamlined attachment mechanism that provides superior firmness while occupying minimal space. This substitution eliminates the need for bulky overlapping structures, thereby improving cable-terminal firmness while reducing plug connector size

AI summary
A plug connector includes a plug housing having a plurality of side walls forming a cavity, a spacer having a plate shape and dividing the cavity into a pair of halves, a plurality of conductive terminals disposed on opposite sides of the spacer, a connector engagement component, and a pull tab. The connector engagement component has a first engagement portion releasably engaging a second engagement portion of a socket connector and a fixing portion detachably secured to the side walls of the plug housing. The pull tab is movable between the plug housing and the connector engagement component in a direction towards or away from a cable connected to the conductive terminals. Pulling of the pull tab in a pulling direction towards the cable enables release of an engagement between the first engagement portion and the second engagement portion, separating the plug connector from the socket connector.
