Wire Harness Band Clamp Geometry for Easier Lock Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing band clamps for wire harnesses face challenges in improving the insertion property of the band part into the band insertion port of the lock part.
Innovation Solution
The band clamp design includes a flange part with an inclined guide surface and tapered surfaces at the open end of the band insertion port, positioned to guide and secure the band part effectively, enhancing its insertion into the lock part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the band insertion port is designed with conventional geometry, then the structure is simple, but the insertion property of the band part into the lock part is insufficient
Solution Approach 1:
The guide surface is provided in advance on the flange part to guide the band part toward the band insertion port before insertion occurs. This preliminary guiding action ensures proper alignment and improves insertion reliability without requiring complex active control mechanisms.
Solution Approach 2:
Tapered surfaces with curved geometry are provided at the open end of the band insertion port. These curved surfaces facilitate the insertion of the band part by providing a gradual transition and reducing resistance during insertion, thereby improving insertion property without adding complex mechanical components.
2Reliability
If the band part is loosely fitted into the lock part, then the structure is simple, but the band part may detach from the lock part
Solution Approach 1:
The guide surface and tapered surfaces are designed in advance to pre-align and pre-position the band part correctly as it approaches the band insertion port. This preliminary positioning ensures that the band part engages securely with the lock part, preventing detachment without requiring additional active locking mechanisms.
Solution Approach 2:
The asymmetric configuration of the guide surface and tapered surfaces creates a one-way insertion path that facilitates easy insertion while providing mechanical interference that prevents reverse movement or detachment of the band part from the lock part.

AI summary
A band clamp includes a clip part, a flange part, a lock part, and a band part. The flange part is provided with a guide surface inclined toward the other end side in an attachment direction as it is separated from an open end of a band insertion port toward one end side in a width direction of the flange part. The open end is provided with a pair of tapered surfaces inclined so as to spread toward both sides in an axial direction as it is closer to the one end side in the width direction of the flange part. The lock part protrudes such that one end side in the attachment direction of the open end is positioned closer to the one end side in the width direction of the flange part than the other end side.
