Terminal Cover Turn Regulating Portion for 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 cable 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 to the covered area without interfering with cable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is held open during cable connection, then cable connection is 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 serve itself by automatically maintaining the open position through its own structural features. The regulating surface on the cover contacts the cable mounting portion, creating a self-locking mechanism that holds the cover open without external intervention. This self-service function eliminates the need for the user to continuously hold the cover with one hand while connecting cables with the other, allowing single-handed operation.
2Ease of operation
If a turn regulating portion is added to prevent cover movement, then cable connection becomes easier, but the number of components increases
Solution Approach 1:
The turn regulating portion is merged with the cover itself, forming an integrated structure rather than a separate component. The cover includes a protrusion or regulating surface that directly interacts with the cable mounting portion to provide the turning regulation function. This merging approach achieves the cover opening control function while minimizing the increase in component count, as the regulating feature is incorporated into the existing cover structure.
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 foreign matter adherence, achieved with a reduced number of components at lower costs.
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.
