RETENTION MECHANISM HAVING IMPROVED FATIGUE STRENGTH |
摘要 |
A retention latch mechanism having a retention spring of a first connector engageable with a retention feature of a second connector. The retention spring may include a spring arm having a distal, curved retaining portion that is resiliently received within the retention feature and a reinforced portion that is proximal of the distal retaining portion. The reinforced portion includes a layer having residual compressive stress to inhibit fatigue failure during repeated cycling of the latch mechanism. The reinforced portion may be formed by a cold working method, such as shot peening a select region of the spring arm. The reinforced portion is formed to inhibit fatigue failure during repeated cycling of the latch mechanism. Methods of forming a retention mechanism having a retention spring with a reinforced portion are provided herein. |
