Shield Conductor Ground Clamp With Contoured Spring Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection devices for shield conductors are complex, costly, and require multiple components, making them difficult to operate and maintain, while ensuring reliable and durable contact with earthing sections in aggressive environments.
Innovation Solution
A connection device with an adjustable spring element featuring a clamping leg and contact sections that form a curved or angled contour, allowing for elastic adaptation to the shield conductor, ensuring a durable and reliable connection that compensates for shape changes and tolerances, and is easy to operate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shield conductor is connected to a grounding section using conventional methods, then the connection can be established, but the connection point becomes accessible to water and dust, leading to corrosion and safety hazards
Solution Approach 1:
The connection device is nested within the cable assembly structure, with the shield conductor connection point housed inside the cable conduit or protective sheath. This nesting approach protects the connection point from external environmental factors like water and dust while maintaining electrical connectivity, directly resolving the contradiction between establishing a reliable connection and preventing harmful factor intrusion.
2Ease of operation
If the shield conductor is exposed for connection purposes, then connection can be made, but bacterial growth occurs and safety is compromised
Solution Approach 1:
An intermediary protective structure or sealed connection component is introduced between the shield conductor and the external environment. This intermediary element allows electrical connection to be made while preventing direct exposure to air and moisture that would otherwise promote bacterial growth, thus maintaining both operational ease and hygiene safety.
3Reliability
If the insulation layer is removed for connection, then electrical contact is achieved, but the connection point becomes vulnerable to environmental damage
Solution Approach 1:
Protective measures are taken in advance by designing a sealed or protected connection structure that maintains insulation and environmental protection even after the shield conductor connection is made. The connection device is pre-configured with protective features that prevent environmental damage before exposure occurs, resolving the contradiction between achieving electrical contact and maintaining protective strength.

AI summary
The invention relates to a connection device (1) for connecting a shield conductor (20) of an electric line (2) to a grounding section (3), comprising a housing (10) that encloses a receiving area (12) into which an electric line (2) can be inserted along a longitudinal axis (L) together with a shield conductor (20). Additionally, a spring element (11) which is arranged on the housing (10) in an adjustable manner is provided, said spring element having a clamping limb (13) and being movable out of an open position into a clamping position relative to the housing (10) in order to act on a shield conductor (20) of an electric line (2) inserted into the receiving area (12) by means of the clamping limb (13) in the clamping position, wherein the clamping limb (13) has a contact section (130) for acting on the shield conductor (20), said contact section having a contoured contact section (K), which is curved or angled at least in some sections on a face facing the shield conductor (20) when viewed on a plane (A) perpendicular to the longitudinal axis (L).
