Position Limiting Plug Structure for Stable HDMI Connector Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Composite connectors with stacked multi-port structures suffer from instability in HDMI plugs due to the lack of effective positioning, leading to increased detachment risk, especially when only the lower HDMI insertion port is used.
Innovation Solution
A position limiting plug with an extending structure and a gap design that inserts into the first insertion port, featuring an abutting portion that rotates to apply an elastic pressing force on the male connector plug, enhancing stability without affecting the connector's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a composite connector with stacked multi-port structure is used, then the connector can support multiple port interfaces (DP and HDMI), but the HDMI plug stability is reduced and detachment risk increases
Solution Approach 1:
The patent introduces a position limiting plug as an intermediary component inserted into the DP insertion port. This mediator provides additional support and positioning for the HDMI plug, preventing upward displacement and detachment while maintaining the composite connector's multi-port functionality.
Solution Approach 2:
The position limiting plug is divided into functional segments: a main body portion inserted into the DP port, and an extending structure with an abutting portion that contacts the HDMI plug. This segmentation allows each part to perform its specific function independently while working together to solve the stability problem.
2Reliability
If the position limiting plug is inserted into the first insertion port, then the male connector plug stability is improved, but the device structure becomes more complex
Solution Approach 1:
The position limiting plug serves multiple functions: it limits the position of the male connector plug, provides structural support, and maintains the integrity of the connector assembly. By consolidating these functions into a single component, the overall device complexity is minimized while achieving improved reliability.
3Reliability
If the abutting portion is designed to rotate toward the gap, then the pull-out force is improved and detachment is prevented, but the manufacturing precision requirements increase
Solution Approach 1:
The abutting portion is designed to be rotatable relative to the main body, transitioning from a static to a dynamic structure. This rotational capability allows the abutting portion to automatically adjust its position and apply pressing force to the male connector plug, improving pull-out force while accommodating manufacturing tolerances through its dynamic adjustment.
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
The solution improves the pull-out force and prevents detachment of the male connector plug, while altering the reaction force to protect the pins and maintain connector stability, allowing easy detachment when not in use.
Implementation Method 1
the abutting portion is configured to abut against the male connector plug so as to rotate toward the gap

AI summary
A position limiting plug includes a main body and a flexible arm structure. The main body has a stop wall. The flexible arm structure extends from a front side of the main body and outwardly towards a direction away from the stop wall, and is configured to be inserted into a first insertion port of a connector. There is a gap between the flexible arm structure and the main body. A bottom surface of the flexible arm structure has an abutting portion adjacent to the gap, and a bottom end of the abutting portion is lower than a bottom surface of the main body. After a male connector plug is inserted into a second insertion port of the connector, the abutting portion is configured to abut against the male connector plug so as to rotate toward the gap.
