Terminal Cover Stop Structure for Stable Cable Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover opening and dosing devices for mobile devices require users to hold the cover open with one hand while connecting cables, compromising operability due to the resilience of the coupling portion causing the cover to move and hinder connection.
Innovation Solution
A cover opening and dosing device with a turn regulating portion that prevents the cover from turning in either the opening or closing direction by coming into surface-to-surface contact with the cabinet, allowing the cover to be fixed in the open position and maintaining accessibility without obstructing cable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is held open by manual pressure to prevent forward movement, then cable connection becomes possible, but the user must use both hands (one to hold cover, one to connect cable)
Solution Approach 1:
The turn regulating portion enables the cover to self-regulate its position automatically. Once opened, the cover's own structure (through the turn regulating portion engaging with the cabinet) maintains the open position without requiring external manual force, allowing the user to immediately proceed with cable connection using both hands freely.
2Adaptability or versatility
If the cover is allowed to move freely due to coupling portion resilience, then the cover can be easily opened and closed, but the cover position becomes unstable during cable connection
Solution Approach 1:
The system transitions from a purely resilient coupling mechanism to a dynamic system with two states: during opening/closing operations, the resilient coupling portion provides flexibility; when fully open, the turn regulating portion engages to provide positional stability. This dynamic adaptation allows the cover to be both easy to operate and stable when needed.
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
Enhances operability by allowing easy connection and removal of cables without applying load on them, preventing poor connections and maintaining the cover's position to prevent dust and moisture adherence.
Implementation Method 1
a turn regulating portion capable of preventing the cover, when the cover is at a position for opening the portion to be covered, from turning in a cover dosing direction

AI summary
In the cover opening and dosing device of the present invention, a terminal cover 21 includes a turn regulating portion 24. The turn regulating portion 24 can prevent the terminal cover 21 from turning in a cover dosing direction due to resilience of coupling portions 22 and 23 when the terminal cover 21 is moved to a cover opening position. Thus, when connecting a cable to a terminal, the terminal cover 21 does not hinder the connection, so that the cable can be connected to the terminal with ease. It is possible to achieve a configuration of holding the terminal cover capable of opening and dosing the terminal open with ease and at low cost.
