Solution Overview

Problem

Traditional electrical connections between electronic components and circuit boards often result in conductive wire damage due to friction and occupy valuable space, leading to EMI issues.

Innovation Solution

A connection structure using a conductive connector and insulated connector, where the conductive wire does not extend through a through-hole, preventing damage and minimizing EMI, with a fastener securing the conductive connector through the hole, ensuring reliable and space-efficient electrical connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the conductive wire extends through the wire hole to connect the inductor to the terminal stage, then electrical connection is achieved, but the conductive wire may be damaged due to friction with the edge of the wire hole

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidwire damage from friction
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a connector as an intermediary component between the inductor and terminal stage. The connector has a body portion that receives the conductive wire and a connection portion that electrically connects to the terminal stage, eliminating direct friction between the wire and wire hole edge while maintaining electrical connection reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the conductive wire extends out of the wire hole to reach the terminal stage, then electrical connection is established, but the extension occupies space and affects the layout of the circuit and other components

Engineering Contradiction:
Improveelectrical connectionVSAvoidcircuit board layout space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent transitions the connection approach from a two-dimensional wire extension across the circuit board surface to a three-dimensional vertical connection through the connector body. The connector extends in the thickness direction of the circuit board, allowing electrical connection without occupying valuable planar layout space

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If the conductive wire extends a certain length to connect components, then electrical connection is achieved, but the extension length causes EMI (Electromagnetic Interference) problems

Engineering Contradiction:
Improveelectrical connectionVSAvoidEMI from wire extension
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the excessive wire extension that causes EMI by using a connector with integrated connection functionality. The connector provides a direct electrical path from the inductor to the terminal stage without requiring long wire extensions, thereby eliminating the source of electromagnetic interference

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An electrical connection of an electronic component 30, such as an inductor, and a circuit board 20 is implemented as follows. The circuit board has a through-hole 21 and is located at a distance from an inner bottom surface 101 of a case 10. The electronic component is disposed around the through-hole and between the inner bottom surface and the circuit board. The electronic component has a conducting wire 31 and a conducting plate 32. A conductive connector 40 is disposed between the through-hole and the conducting plate and electrically connected to the conducting plate. The electronic component is electrically connected to the circuit board through the conductive connector. A insulated connector 50 corresponds to the conductive connector and is located between the conducting plate and the inner bottom surface. A fastener 60 is connected to the conductive connector through the through-hole. Thus, a good electrical connection between the electronic component and the circuit board is achieved.
