Bus Bar Connector With Self-Actuating Contact Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for flat conductors require multiple operations to achieve sufficient contact pressure, leading to potential operator errors and unstable conductive performance.
Innovation Solution
A connector design that includes an inserted portion, a conductive portion, and a pressing portion, where the pressing portion is displaced to elastically deform the conductive portion, generating an elastic force to increase contact pressure with the bus bar, thereby simplifying the connection operation and ensuring consistent contact pressure without requiring additional operation steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a pressing member is rotated to increase contact pressure between the flat conductor and terminal, then the contact pressure is improved, but the operation complexity increases requiring at least two separate operations
Solution Approach 1:
The pressing portion is integrated with the conductive portion to form a unified structure. When the bus bar is inserted, the pressing portion automatically displaces and presses the conductive portion, combining the insertion action with the pressure application action into a single operational step, thereby eliminating the need for separate rotation operations.
Solution Approach 2:
The pressing portion automatically activates upon bus bar insertion. The insertion of the bus bar itself triggers the displacement of the pressing portion, which then automatically presses the conductive portion to generate contact pressure. This self-activating mechanism eliminates the need for additional manual operations to achieve proper contact pressure.
2Stress or pressure
If multiple operations are required to achieve sufficient contact pressure, then the contact pressure can be ensured, but the reliability decreases due to potential operator errors
Solution Approach 1:
The pressing portion automatically activates upon bus bar insertion. The insertion of the bus bar itself triggers the displacement of the pressing portion, which then automatically presses the conductive portion to generate contact pressure. This self-activating mechanism eliminates the need for additional manual operations to achieve proper contact pressure.
Solution Approach 2:
The pressing portion is pre-configured to automatically press the conductive portion upon bus bar insertion. The structure is designed so that the insertion action inherently triggers the pressing action, ensuring contact pressure is established as part of the insertion process itself, before any subsequent operations could occur.
3Ease of operation
If the pressing portion structure is added to automatically press the conductive portion, then the ease of operation is improved by reducing operation steps, but the device complexity increases
Solution Approach 1:
The pressing portion is integrated with the conductive portion to form a unified structure. When the bus bar is inserted, the pressing portion automatically displaces and presses the conductive portion, combining the insertion action with the pressure application action into a single operational step, thereby eliminating the need for separate rotation operations.
Solution Approach 2:
The pressing portion automatically activates upon bus bar insertion. The insertion of the bus bar itself triggers the displacement of the pressing portion, which then automatically presses the conductive portion to generate contact pressure. This self-activating mechanism eliminates the need for additional manual operations to achieve proper contact pressure.
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 connector effectively suppresses bus bar displacement and ensures stable conductive performance by eliminating the need for separate operation steps to increase contact pressure, thereby preventing insufficient contact pressure due to operator errors.
Implementation Method 1
the pressing portion presses the conductive portion to elastically deform at least a part of the conductive portion. The conductive portion is configured to cause, when the conductive portion being pressed by the pressing portion and elastically deformed, an elastic force generated with the elastic deformation to act on the bus bar to increase a contact pressure with respect to the bus bar
