Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing circular connector units for shielded electrical cables require different insulating bodies and shielding sleeves for connector and mating connector parts, leading to increased production costs and storage expenses due to design mismatches.
Innovation Solution
A circular connector unit design where the shielding sleeve has axially extending sleeve segments with uniform radial offsets, allowing identical sleeves to be plugged together with a specific rotational offset, enabling the same shielding sleeve to be used for both connector and mating connector parts, and the insulating body is arranged to accommodate both pin and socket-shaped contacts symmetrically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different insulating bodies and shielding sleeves are used for connector and mating connector parts, then reliable electrical contact and proper shielding are achieved, but production costs and storage expenses increase
Solution Approach 1:
The shielding sleeve is designed with radial offsets that enable it to function in both connector and mating connector configurations. By rotating the shielding sleeve to different angular positions, the same component can be used for both male and female connectors, eliminating the need for separate dedicated components and reducing production and storage costs while maintaining reliable electrical contact and shielding performance
2Adaptability or versatility
If different insulating bodies and shielding sleeves are used for connector and mating connector parts, then proper connector functionality is achieved, but storage costs increase
Solution Approach 1:
The shielding sleeve incorporates radial offsets that allow it to adapt to both connector and mating connector roles through rotational positioning. This universal design reduces the variety of components that need to be stored and managed, lowering storage costs while maintaining full adapter functionality for different connector types and configurations
3Ease of manufacture
If radial offsets are introduced in sleeve segments, then the same shielding sleeve can be used for both connector and mating connector parts, but manufacturing precision requirements increase
Solution Approach 1:
The shielding sleeve is divided into multiple axially extending segments separated by longitudinal slots, with radial offsets applied to alternating segments. This segmentation allows the offsets to be manufactured using standard forming processes without requiring high-precision machining, as each segment can be formed independently and the cumulative effect achieves the desired universal functionality while maintaining manufacturing feasibility

AI summary
Circular connector unit (6, 6') for shielded electrical cables, with an insulating body (8) enclosed by a shield sleeve (7), in which several electrical socket- and/or pin-shaped plug contacts (5, 5') are arranged in receiving chambers (16), wherein the shield sleeve (7) is locked to the insulating body (8). According to the invention, the plug-in end (12) of the umbrella sleeve (7) has an even number of axially extending sleeve segments (14) separated by longitudinal slots (13), which are preferably designed alternately as short and long sleeve segments (14', 14"). Successive sleeve segments (14) preferably each have a uniform radial offset to one another in alternating directions, wherein the sleeve segments (14) of two identically designed umbrella sleeves (7) can be plugged into one another according to the invention with a rotational offset in the circumferential direction of 360 degrees divided by the number of sleeve segments (14).
