Reduced Assembly Time and Increased Reliability with Bossard’s Complete Grounding Solution

The Challenge: Reliable Grounding Connections

For a leading rolling stock manufacturer, ensuring reliable earthing connections inside train carriages is critical for both safety and performance. Their previous grounding system relied on a screw-based solution with multiple components. This setup was:

• Complex and time-consuming to install
• Prone to failure, as the grounding connections were often torn out after assembly
• Operationally costly, increasing the total cost of ownership (TCO)

With growing production demands, the customer needed a solution that simplified installation, minimized failures, and guaranteed long-term vibration resistance.

Our Solution: Grounding Tailored to the Customer's Needs

We introduced a complete grounding solution combining:

• Grounding clips that easily attach to the trunking edge, replacing time-intensive screw mounting
• Flat receptacles with a locking mechanism, providing high tensile strength and vibration resistance

The solution was developed as part of a consultation process involving Bossard's Product Management:

• Initial interest sparked during a Bossard Roadshow
• Multiple on-site workshops with engineers
• Validation of key requirements: cross-sections, sheet thickness, tensile strength
• Internal and customer-side pull-out tests (EN60352-2) passed successfully

Rather than offering just a part, we delivered a holistic solution tailored to our customer's operational challenges.

The Outcome: Increased Efficiency, Reliability and a Satisfied Customer

The new grounding system delivered measurable improvements:

• Increased efficiency: The new streamlined installation process significantly saves assembly time.
• Reduced TCO: Faster installation and fewer failures drive cost savings.
• Improved reliability: The robust design with high tensile strength ensures durability.
• Greater satisfaction: Technicians welcomed the easier-to-use solution.
