Elastic Inner Conductor for Signal Interference in Communication Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors have a complex structure due to the separation of performance transmission and elastic devices, leading to challenging assembly and interference issues with escaping signals.
Innovation Solution
A connector design integrating an inner conductor, an outer conductor, and an insulating member with an elastic inner conductor that includes an inclinedly oriented free end portion and a protrusion, allowing selective contact with a terminating conductor to manage termination and untermination states, eliminating the need for separate spring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a switch connector with separate selective contact elastic device and inner conductors is used to prevent signal interference, then signal transmission reliability is improved, but device complexity increases and assembly becomes difficult
Solution Approach 1:
The patent combines the selective contact elastic device and the inner conductors into an integrated elastic inner conductor assembly. The elastic inner conductor includes contact portions that can selectively contact different outer conductors, merging previously separate components into a unified structure that reduces complexity while maintaining signal transmission reliability.
Solution Approach 2:
The elastic inner conductor serves multiple functions simultaneously: it provides signal transmission, acts as a selective contact mechanism, and enables port switching. This multi-functional design eliminates the need for separate dedicated components for each function, thereby reducing overall device complexity.
2Object-affected harmful factors
If loads are added to absorb escaping signals in unused ports, then signal interference is prevented, but volume and manufacture cost significantly increase
Solution Approach 1:
The patent extracts the signal absorption function from separate load components and integrates it into the elastic inner conductor structure itself. The elastic inner conductor's contact geometry and material properties inherently manage escaping signals without requiring additional dedicated load components, thereby reducing volume.
3Adaptability or versatility
If multiple separate components are used for port selection, then functional performance is achieved, but assembly and performance adjusting become difficult
Solution Approach 1:
The patent merges the port selection mechanism with the signal transmission path by integrating the elastic inner conductor to perform both functions. This unified structure eliminates the need for separate assembly of multiple components and simplifies performance adjustment, as the elastic inner conductor's geometry can be optimized during manufacturing to achieve desired port selection characteristics.

AI summary
A connector comprises an inner conductor (1) and an outer conductor (2); an insulating medium (3) is provided between the inner conductor and the outer conductor, the insulating medium forming an unclosed cavity, and an opening of the unclosed cavity being a port for termination. The inner conductor comprises a first inner conductor (40) and an elastic inner conductor (60), the first inner conductor and the elastic inner conductor being disposed in the unclosed cavity; the elastic inner conductor (60) comprises an elastic member (61) having an inclinedly oriented free end portion (611) and a protrusion (612) projecting towards the first inner conductor (40); in the case where the connector is unterminated, the protrusion of the elastic inner conductor contacts the first inner conductor, and in the case where the connector is terminated, the inclinedly oriented free end portion (611) is moved substantially laterally by a terminating conductor (50) vertically inserted through the port for termination, such that the protrusion (612) is separated from the first inner conductor (40) and the terminating conductor (50) is in contact with the elastic inner conductor (60). The connector solves the problem of a complex connector structure caused by separation of a performance transmission device and an elastic device of a connector in the prior art.
