Which statement about strain relief is true?

Which statement about strain relief is true?

• A. It protects the insertion of the cable into the transducer housing.
• B. It reduces the risk of cable damage at the connection point.
• C. It adjusts the focal length of the ultrasound beam.
• D. It has no role in safety.

Answer: (A)

Strain relief is a mechanical feature designed to absorb and redirect bending or pulling forces so they don’t stress the delicate connection where the cable meets the transducer housing. By protecting the insertion point into the transducer housing, strain relief keeps the electrical contacts intact and prevents wear or damage at the entry where the cable connects. This helps maintain reliable signal transmission and reduces the chance of a loose connection or broken conductors. It isnures safety in that a damaged entry could lead to exposed conductors, but the primary idea is guarding that entry point against mechanical stress. Focal length is set by the transducer’s optics and beamforming system, not by strain relief.
