Dual-Latching Rail Connector for Corrosion-Resistant Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting apparatuses for current-carrying elements to rail elements lack a secure and reliable fastening mechanism, particularly in terms of resistance to temperature and corrosion, which can lead to unreliable grounding of shield conductors over the service life of electrical systems.
Innovation Solution
A connecting apparatus with a receiving body for fastening a current-conducting element, featuring first and second latching arms joined to opposite transverse sides of the receiving body, which provide a secure fastening to the rail element through linear and point contacts, ensuring stability and resistance to environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single latching arm is used to fasten the connecting apparatus to the rail element, then the device complexity is reduced, but the reliability of the connection deteriorates due to insufficient resistance against temperature and corrosion
Solution Approach 1:
The fastening mechanism is segmented into two separate latching arms (first latching arm and second latching arm) that are joined to opposite transverse sides of the receiving body. Each latching arm independently engages with the rail element, providing distributed contact points that enhance connection reliability while maintaining manageable device complexity through modular segmentation.
2Reliability
If multiple latching arms are added to improve fastening security, then the reliability of grounding is improved, but the device complexity increases
Solution Approach 1:
The receiving body is segmented with two latching arms positioned on opposite transverse sides, creating a balanced and symmetrical structure that improves grounding reliability without excessive complexity
Solution Approach 2:
Both latching arms perform the same fastening function, providing redundant and reliable grounding contact. This universal approach where identical components perform the same function enhances reliability while keeping the design simple and maintainable.
3Ease of manufacture
If latching arms are joined to longitudinal sides of the receiving body, then the ease of manufacture is improved, but the stability of the connection deteriorates
Solution Approach 1:
The latching arms are positioned on opposite transverse sides rather than on longitudinal sides, creating a transverse symmetry that provides superior mechanical stability. This asymmetric positioning relative to the rail element engagement direction enhances connection stability while remaining manufacturable through standard forming processes.

AI summary
A connecting apparatus for connecting a current-carrying element to a rail element includes: a receiving body on which the current-conducting element is fastenable, the receiving body having a first transverse side and a second transverse side opposite the first transverse side, and a first longitudinal side and a second longitudinal side opposite the first longitudinal side; a first latching arm for fastening the connecting apparatus to the rail element; and a second latching arm for fastening the connecting apparatus to the rail element. The first latching arm is joined to the first transverse side of the receiving body. The second latching arm is joined to the second transverse side of the receiving body.
