Top-Loading Header Component for Shielded Inductive 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 requiring lateral openings that compromise insulation and shielding.
Innovation Solution
A header component with a housing that confines the inductive component inside a cavity accessible via a top opening, allowing for easy vertical placement using pick-and-place techniques, and featuring terminals that protrude from the bottom side for secure electrical connection without compromising insulation or shielding, and an optional cover for protection and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a lateral opening is provided in the housing for inserting the inductive component, then the assembly process can be simplified, but the insulation and shielding of the inductive component are compromised
Solution Approach 1:
Instead of providing a lateral opening 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 leads extending downward to connect to terminals at the bottom. This inversion resolves the contradiction by maintaining complete enclosure (preserving insulation and shielding) while still enabling simplified assembly through the top opening.
2Extent of automation
If the inductive component is inserted from the top opening, then automation-friendly assembly is enabled, but the footprint on the substrate increases
Solution Approach 1:
The patent utilizes the vertical dimension by providing a top opening in the housing, allowing the inductive component to be inserted from above. This dimensional approach enables automation-friendly assembly (using pick-and-place machines) without increasing the horizontal footprint on the substrate, as the component is inserted vertically through the housing rather than requiring lateral access that would expand the board-level footprint.
3Ease of manufacture
If terminals protrude from the bottom side of the housing, then electrical connection to the substrate is simplified, but the insulation distance to the substrate is reduced
Solution Approach 1:
The housing acts as an intermediary structure between the inductive component and the substrate. The terminals protrude from the bottom side of the housing to establish electrical connection with the substrate, while the housing walls maintain the required insulation distances. This intermediary approach allows simplified electrical connection (terminals easily accessible at the bottom) while preserving insulation reliability (through the housing barrier).

AI summary
A header component for mounting an inductive component on a substrate comprises a housing for housing the inductive component inside a cavity, wherein the housing confines the cavity to a bottom side and to at least three lateral sides, and wherein the housing comprises a top opening to the cavity at a top side opposite to the bottom side, wherein the top opening is configured for inserting the inductive component into the cavity via the top opening. The header component further comprises a plurality of terminals for electrically connecting the inductive component to the substrate, wherein the terminals outwardly protrude from the housing at the bottom side. Further disclosed are an inductive device and a method for assembling an inductive device.
