Connector Shielded Cable Conductive Plastic Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The creation of a conductive connection between a cable shield and a connector requires significant design and assembly effort, making it complex and time-consuming.
Innovation Solution
A sprayed shielding sleeve made of electrically conductive material, such as conductive plastic or a plastic/metal hybrid, is used to connect the cable shield directly to the connector, ensuring effective shielding with simplified production processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used to create a conductive connection between cable shield and connector, then reliable shielding connection is achieved, but design and assembly effort is significant and process is complex
Solution Approach 1:
The patent combines the cable shield connection and connector housing into a single integrated component. The housing is designed with an integrated shield connection element that directly contacts the cable shield, eliminating the need for separate connection components and reducing assembly steps while maintaining reliable electrical connection.
Solution Approach 2:
The connector housing serves multiple functions: it provides mechanical protection, structural support, and electrical shielding connection. The housing is designed to simultaneously accommodate conductors, provide insulation, and establish conductive connection with the cable shield through its integrated shield connection element.
2Reliability
If traditional assembly methods are used for shield connection, then adequate shielding is achieved, but production time and assembly effort increase
Solution Approach 1:
The shield connection capability is pre-integrated into the housing design during manufacturing. The housing is produced with built-in shield connection elements already in place, so that during final assembly, the cable shield simply needs to be positioned and contacted, eliminating time-consuming separate connection steps.
Solution Approach 2:
The housing is designed with distinct functional zones: conductor accommodation areas, insulation regions, and dedicated shield connection elements. This segmentation allows for optimized manufacturing processes and simplifies assembly by clearly defining where and how the shield connection occurs.

AI summary
The plug connector (6) has a cable (1) connected to the connector, and a conductor (2) insulated by a surrounding cladding (3). The conductor is partially enclosed by a cable shield (4), and is connected to a contact holder (7) of the connector. The cable shield is conductively connected with the connector. An extruded shield element e.g. circumference closed shield sleeve (10), is made of electrical conductive plastic e.g. electrical conductive polymer or plastic/metal hydride material, and is conductively connected with the cable shield. An independent claim is also included for a method for producing a plug connection.
