FLEXURE FACTS

Solved Application Story # 25

INDUSTRIAL - Electrical Connection


THE CHALLENGE

A manufacturer of xenon flash lamps found the lamps increased in length from the heat generated when the lamp was on. The company wanted the electrical connection to the lamp to have these features:

1. Compliant electrical connection to the lamp.
2. Compression compensation for thermal growth.
3. Threaded stud for electrical supply.
4. Corrosion resistant since water will be flowing over connection. 

THE SOLUTION

The final machined spring design should be considered a premier example of Value Engineering. This concept encourages that a single item perform as many primary and secondary functions as possible; the more the better. The electrical connection for the lamp was accomplished by the slotted end receiver. The HELI-CAL® Flexure was sized to provide the desired thermal growth compensation and not become a limiting resistive element since it is in the electrical current path. The threaded end addressed the electrical attachment requirement, and the whole item was manufactured from corrosion resistant 303 Stainless Steel.


THE ANSWER


HELI-CAL Flexure "Machined" Spring # 228
