Socket Contact Carrier with Arc Support for Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sockets for telecommunications and data transmission systems suffer from poor transmission properties and increased wear due to the relative movement between conductor track sections and their supporting elements, leading to reduced signal quality and short service life.
Innovation Solution
The second end area of the flexible printed circuit board is supported by an arc-like insulating support part with freely extending fingers, fixed to a contact carrier in the housing, which prevents relative movement and enhances contact pressure through a leaf spring mechanism, ensuring the conductor track sections remain close to the first end area and minimizing wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conductor track sections are supported by disc-shaped guiding and positioning elements with resilient support arms, then the conductor track sections are mechanically connected and separated, but the contact points are far from the end of the printed circuit board leading to poor transmission properties
Solution Approach 1:
The patent employs an arc-like support part with a curved geometry that follows the bend of the flexible printed circuit board. This curved support structure allows the conductor track sections to be positioned closer to the first end area while maintaining proper mechanical support and electrical contact, thereby improving transmission properties by reducing the effective length of the conductor path.
2Reliability
If the conductor track sections are separated by disc-shaped guiding elements, then the individual tracks are mechanically stable, but relative movement occurs between the support elements and conductor track sections causing wear
Solution Approach 1:
The patent integrates the support function and the separation function into a single arc-like support part structure. This unified component provides both mechanical support and lateral separation for the conductor track sections simultaneously, eliminating relative movement between separate support elements and conductor tracks, thereby preventing wear and extending service life.
3Shape
If the flexible printed circuit board is bent by more than 180° to form finger-like conductor track sections, then the contact areas are compact and aligned, but the conductor track sections are vulnerable to wear and transmission degradation
Solution Approach 1:
The patent incorporates the arc-like support part that provides pre-positioned mechanical support and cushioning for the bent conductor track sections. This support structure is designed to absorb stresses and prevent excessive movement before wear or transmission degradation can occur, thereby protecting the vulnerable bent conductor tracks while maintaining their compact aligned configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves excellent transmission properties, suitable for category 8 standards, with significantly reduced wear and tear, ensuring a long-lasting and reliable service life by maintaining contact points close to the first end area and preventing relative movement between the support part and conductor track sections.
Implementation Method 1
a first end of a leaf spring is clamped and fixed between a housing part and the further component of the contact carrier, which is separated by a bend in it. The leaf spring merges into spring fingers at the second end, which abut against the support part in the area of each of the fingers on the side facing away from the isolated conductor track sections.
