Resin-Supported Block Coil Structure for Terminal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing block coils lack structural support for their terminals, leading to a risk of short circuits and terminal displacement.
Innovation Solution
The integration of a resin body with embedded terminals provides structural support, preventing short circuits and terminal displacement by ensuring terminals are connected to specific conductive patterns and spaced appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals are extended over the magnetic core without support structure, then electrical connection is achieved, but the risk of short circuit and terminal displacement increases
Solution Approach 1:
A resin body is introduced as an intermediary material to embed and support the terminals. The resin body serves as a mediator between the terminals and the magnetic core, providing mechanical support and insulation while maintaining electrical connectivity through the embedded terminals.
Solution Approach 2:
The block coil is constructed as a composite structure combining resin material with embedded terminals. This composite approach integrates the insulating properties of resin with the conductive properties of terminals, creating a unified structure that prevents short circuits while maintaining electrical functionality.
2Reliability
If terminals are extended over the magnetic core without support structure, then electrical connection is achieved, but terminal displacement risk increases
Solution Approach 1:
The resin body is prepared in advance with embedded terminals in their correct positions before assembly. This preliminary action ensures that terminals are pre-positioned and secured, preventing displacement during subsequent assembly and operation of the magnetic component.
Solution Approach 2:
The resin body acts as a mediator that mechanically secures the terminals in their intended positions. By embedding terminals within the resin structure, the resin serves as a positioning fixture that prevents terminal displacement during assembly and operation.
