Solution Overview
Problem
Existing connection holders for coaxial cables require complex production processes and multiple components, leading to increased costs and complexity in manufacturing, particularly due to the need for electrically insulating housings and insert strips.
Innovation Solution
A connection holder design featuring two electrically conductive holder elements with a contact section that forms a clamping force to create a low-resistance electrical contact with the cable shield, utilizing a simple embossing process and reducing the number of components through a stamping and bending process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrically insulating housing with an insert strip is used, then electrical insulation is provided, but the number of production steps and components increases
Solution Approach 1:
The patent merges the insulating housing and the conductive contact element into a single integrated component. The connection holder consists of a single insulating body with an integrated contact section that directly contacts the cable shield, eliminating the need for separate insert strips and reducing assembly steps while maintaining electrical insulation reliability
2Reliability
If multiple components are used, then functional requirements are met, but manufacturing costs and production complexity increase
Solution Approach 1:
The patent combines multiple functional components into a single molded part. The insulating housing and contact element are integrated into one piece that can be produced in a single injection molding process, significantly reducing manufacturing costs and production complexity while maintaining reliable electrical connection through the integrated contact section
3Reliability
If a clamping force is applied to press the contact surface against the shield, then low contact resistance is achieved, but additional fastening devices may be required
Solution Approach 1:
The patent employs a dynamic clamping mechanism where the connection holder is designed to be clamped relative to itself, creating a self-contained clamping force. The first and second holder elements move relative to each other to press the contact surface against the cable shield, generating the necessary contact pressure without requiring external fastening devices, thus maintaining low contact resistance while simplifying the device structure

AI summary
The invention relates to a connection retainer, a system and a method for producing such a system, the connection retainer being designed to connect a shield of a shielded cable to a carrier component and the connection retainer having a first retainer element and a second retainer element, the first retainer element having a first covering region and the second retainer element having a second covering region, the first covering region and the second covering region delimiting a contact region at least partially, the at least one shielded cable being able to be fed through the contact region. The first retainer element and the second retainer element are electrically conductive. The first retainer element is connected to the second retainer element. The first retainer element can be loaded relative to the second retainer element in order to provide a clamping force in order to press a contact surface of the first covering region against a shield by means of the clamping force and to form an electrical contact and a frictional connection between the contact surface and the shield.
