Header Component With Top-Loading Cavity for Insulated Inductor Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing header components for mounting inductive components on substrates, such as transformers, face challenges in simple and automation-friendly assembly, often compromising insulation and shielding due to lateral openings, and require potting materials that can affect magnetic properties and compliance with regulations.
Innovation Solution
A header component with a housing that confines the inductive component inside a cavity accessible via a top opening, allowing vertical insertion and connection of terminals to the substrate without lateral openings, which enhances insulation, safety distances, and eliminates the need for potting materials, thereby improving assembly efficiency and regulatory compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lateral openings are provided in the housing for inserting the inductive component, then the assembly process is simplified, but the insulation and shielding of the inductive component are compromised
Solution Approach 1:
Instead of providing lateral openings in the housing for inserting the inductive component, the patent inverts the approach by providing a top opening. The inductive component is inserted from the top side of the housing, with its terminals extending downward to contact the substrate. This inversion eliminates lateral openings that would compromise insulation and shielding, while still enabling simplified assembly through the top opening.
2Stability of the object's composition
If potting materials are used to secure the inductive component, then the component is firmly fixed, but the magnetic properties and regulatory compliance are affected
Solution Approach 1:
The patent extracts and eliminates the use of potting materials from the assembly. Instead of using potting materials to secure the inductive component, the design relies on the mechanical structure where the component is inserted through a top opening and held in place by the housing geometry and terminal connections to the substrate, thereby maintaining magnetic properties and regulatory compliance.
3Ease of operation
If the top opening is provided at the same side as the terminals, then the insertion is simplified, but the insulation with respect to the substrate is compromised
Solution Approach 1:
The patent applies asymmetry by positioning the top opening at the top side of the housing while the terminals extend to the bottom side to contact the substrate. This asymmetric arrangement ensures that the insertion path (through the top opening) is separated from the electrical contact points (terminals at the bottom), thereby maintaining proper insulation between the inductive component and the substrate while still enabling simplified insertion.
