PCB Connector Electrode Mechanism to Reduce Terminal Rubbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting printed substrates to devices are burdensome and prone to breakage, as the electrode of the connector alternately rubs against step differences on the terminal part of the printed substrate, increasing the probability of connector and substrate terminal breakage.
Innovation Solution
A connector design featuring an opening with a void between prismatic surfaces, where a first member moves parallel to the generating lines and a second member moves between predetermined points, with an electrode secured to the second member that only contacts the prismatic surfaces at specific points, reducing the likelihood of rubbing and breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrode of the connector alternately rubs against the terminal part of the printed substrate during attachment and detachment, then the connector can be connected and disconnected, but the probability of breakage of the electrode and terminal part increases
Solution Approach 1:
A moving member is introduced as an intermediary between the electrode and the terminal part. This moving member translates the insertion motion into electrode movement, allowing the electrode to approach the terminal part smoothly without direct rubbing contact. The moving member acts as a mediator that converts linear insertion motion into the necessary electrode displacement, reducing wear and breakage risk.
Solution Approach 2:
The electrode is made dynamic through its connection to the moving member. Instead of being stationary, the electrode moves dynamically during insertion and detachment processes. This dynamic configuration allows the electrode to follow the motion of the terminal part, reducing impact and rubbing forces that would otherwise cause breakage.
2Reliability
If the electrode directly contacts the terminal part with step differences, then electrical connection is established, but stress and rubbing increase causing breakage
Solution Approach 1:
The moving member serves as an intermediary mechanism that manages the contact between electrode and terminal part. It controls the approach and separation motions, ensuring that the electrode contacts the terminal part gently at the correct position while avoiding step differences that cause stress concentration and breakage.
3Ease of manufacture
If the connector uses a conventional opening structure, then assembly is simple, but the electrode must rub against step differences causing wear
Solution Approach 1:
The connector incorporates a moving member that introduces dynamic motion to the electrode during operation. This dynamic mechanism is integrated into the connector structure, allowing the electrode to move independently to follow the terminal part's position, thereby reducing wear from rubbing against step differences while maintaining manufacturing feasibility.

AI summary
In order to reduce the probability that an electrode of a connector and a terminal part of a printed substrate are broken, this connector is provided with openings including a void, respectively, in at least one of surfaces perpendicular to generating lines of two prismatic surfaces facing each other with the void therebetween and having parallel generating lines, and at least one of surfaces parallel to the generating lines, and is equipped with: a first member which is disposed in the void, and performs a first movement that is a movement in a direction parallel to the generating lines; a second member which, following the first member, performs a second movement that is a movement in a direction corresponding to the direction of the movement of the first member between respectively predetermined first point and second point.
