Solution Overview

Problem

The soldering process for integrating discrete inductive components to compensate for stray capacitance in differential bus systems is complex and costly, with a high risk of poor connections, affecting the high-frequency transmission behavior.

Innovation Solution

Enclose conductor sections of the differential bus system with a magnetizable material, such as ferrite, to increase inductance and compensate for stray capacitance, using a simple assembly process without soldering.

1Reliability

If discrete inductive components are integrated using soldering to compensate for stray capacitance, then the high-frequency transmission behavior is improved, but the production complexity and cost increase

Engineering Contradiction:

Improvehigh-frequency transmission behaviorVSAvoidproduction complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical soldering process with a magnetizable material enclosure that provides inductance compensation through magnetic properties rather than physical joint formation. The magnetizable material (ferrite) is simply placed around the conductor section, eliminating the need for soldering while achieving the same electrical function of compensating stray capacitance and improving high-frequency transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the approach from modifying connection parameters (soldering quality, joint strength) to modifying the magnetic properties of the environment around the conductor. By introducing a magnetizable material with specific permeability characteristics, the system achieves inductance compensation through parameter change rather than mechanical assembly, reducing production complexity while maintaining reliability.

Solution Approach 1:

The patent employs a simple magnetizable material enclosure that can be easily manufactured and replaced if necessary, rather than requiring expensive soldering processes and specialized inductive components. The magnetizable material acts as a simple, cost-effective solution that achieves the same stray capacitance compensation function without the high production costs associated with precision soldering and discrete component integration.

Solution Approach 2:

The replacement of the soldering mechanical system with a magnetizable material placement system eliminates the need for expensive soldering equipment, skilled labor, and complex quality control processes. The magnetizable material is simply positioned around the conductor, dramatically reducing production cost while maintaining the electrical compensation function.

AI summary

A connecting assembly for electrically connecting a bus subscriber to a differential bus system comprises a differential main conductor portion, which has a first electrical main conductor and a second electrical main conductor. The differential main conductor portion has a first sub-portion and a second sub-portion, which is electrically connected to the first sub-portion. A first terminal for electrically connecting to a first mating terminal of the bus subscriber is formed in the first electrical main conductor between the first sub-portion and the second sub-portion, and a second terminal for electrically connecting to a second mating terminal of the bus subscriber is formed in the second electrical main conductor between the first sub-portion and the second sub-portion. The first and second electrical main conductors are surrounded, at least in the first sub-portion or in the second sub-portion, by one body in each case, said body being made of magnetizable material.
