Reactor Busbar Slide-Hole Assembly Without Screw Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reactor structure requires screwing operations and has a high number of components, leading to reduced productivity.
Innovation Solution
A reactor structure with a busbar that uses a pin to position itself relative to the reactor, eliminating the need for screws by sliding into an elongated slide hole, which restricts movement and ensures secure connection without additional fixing operations, thereby enhancing productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the busbar is screwed to the case to position it relative to the reactor, then the busbar is securely positioned and the coil and external device can be easily connected, but the number of components increases and productivity decreases
Solution Approach 1:
The invention extracts the positioning function from the screwing operation. The slide hole is built into the busbar structure itself, allowing the busbar to be positioned and secured without requiring separate screwing operations or additional fastening components, thus simplifying the assembly process while maintaining positioning accuracy
Solution Approach 2:
The invention merges the positioning function with the busbar structure by integrating the slide hole directly into the busbar. This combines the positioning mechanism and the electrical connection component into a single integrated part, eliminating the need for separate positioning operations and reducing the total number of components
2Strength
If multiple components are used in the reactor structure, then the structural integrity is maintained, but the assembly process becomes complex and productivity is reduced
Solution Approach 1:
The invention merges multiple functions into the busbar structure itself. The busbar with the integrated slide hole combines electrical connection, positioning, and securing functions into a single component, reducing the total number of parts while maintaining the structural integrity needed for reliable operation
Solution Approach 2:
The busbar structure is designed with multi-functionality. The slide hole not only positions the busbar but also secures it to the reactor, eliminating the need for separate positioning and fastening components. This universal design reduces component count while maintaining structural integrity

AI summary
A reactor structure includes: a reactor that has a coil and a core; and a bus bar that electrically connects the coil and an external device. The reactor includes a pin that positions the busbar relative to the reactor, the busbar includes: a first piece that is overlaid onto and connected to a winding wire end portion of the core; a second piece that is connected to the external device; and a body piece that joins the first piece and the second piece to each other. The body piece includes an elongated slide hole that extends in an X direction, the X direction is a direction in which the winding wire end portion and the first piece are arranged side-by-side, and the pin is passed through the slide hole to restrict movement of the busbar in a direction that intersects the X direction and a protruding direction of the pin.
