Busbar Connection Module With Rotation Suppression for Bolt Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing inter-terminal connection structures require multiple bolt operations for attaching and detaching energizing members, leading to inefficiencies in maintenance and operation.
Innovation Solution
A busbar unit with a bolt fastening portion and a connector terminal portion separated by a molded resin portion, featuring a rotation suppressing portion to stabilize the unit during bolt operations, improving efficiency in attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both ends of the energizing member are bolted in the inter-terminal connection structure, then the connection structure is stable and reliable, but the attaching and detaching operations require multiple bolt operations which reduces work efficiency
Solution Approach 1:
The invention divides the connection structure into two distinct parts: a bolt fastening portion for stable electrical connection and a connector terminal portion for efficient attachment/detachment operations. This segmentation allows each part to fulfill its specific function optimally without compromising the other.
Solution Approach 2:
The invention extracts the bolt operation requirement from the attachment/detachment process by providing a separate bolt fastening portion that remains fixed while the connector terminal portion enables tool-free connection and disconnection, thereby eliminating repeated bolt operations.
2Productivity
If the energizing member is designed for easy attachment and detachment, then work efficiency improves, but the unit may become unstable or inclined during bolt operations
Solution Approach 1:
The invention introduces a rotation suppressing portion that acts as a counterbalancing element to prevent the busbar unit from tilting or becoming unstable during bolt operations. This portion provides counteracting support to maintain stability while allowing the connector portion to remain easily attachable and detachable.
Solution Approach 2:
The rotation suppressing portion serves as an intermediary element between the connector terminal portion and the bolt fastening portion, mediating the stability issue by preventing excessive movement or tilting during the attachment and detachment processes.
3Stability of the object's composition
If manual correction of the unit's posture is required during bolt operations, then stability can be maintained, but the complexity and time of operations increase
Solution Approach 1:
The rotation suppressing portion enables the busbar unit to self-stabilize during bolt operations without requiring manual intervention for posture correction. The unit automatically maintains its proper orientation through the mechanical support provided by the rotation suppressing portion, thereby simplifying the overall operation.

AI summary
A busbar unit includes a busbar including a bolt fastening portion and a connector terminal portion, and a molded resin portion for covering the busbar. The molded resin portion includes a connector housing portion for covering the connector terminal portion, an intermediate covering portion for covering an intermediate portion of the busbar extending out from the connector housing portion, a first coupling portion coupling a part of the intermediate covering portion distant from the connector housing portion and the connector housing portion and a second coupling portion coupling a part of the intermediate covering portion closer to the connector housing portion than an intersecting part with the first coupling portion and an intermediate part of the first coupling portion.
