AI Technical Summary
The hook part of the existing moving spring is prone to deformation under stress during use, which leads to unstable forced guide dimensions and even functional failure. In addition, wear generates plastic shavings that affect the reliability of signal transmission.
A flange is provided on the side of the hook to form a superimposed structure. The flange overlaps with the back of the hook to increase the overall strength. The rounded corners reduce edge scratches. Combined with beryllium copper material and opening design, the resistance to deformation and fatigue is improved.
It improves the strength and deformation resistance of the bend, ensures dimensional stability under long-life operation, reduces plastic debris generation, and ensures reliable signal transmission and low contact resistance.

Abstract
Claims
1. A movable spring, comprising a movable spring body (1) and a hook portion (2) bent and connected to the free end of the movable spring body (1) for cooperating with a push arm (4) of a push card, characterized in that: A flange (3) is formed on the side of the hook portion (2). The flange (3) is configured to fold towards the back of the hook portion (2) and overlap with the back surface of the hook portion (2) to form a bent-shaped overlapping flange structure. The overlapping range of the flange (3) covers the bend of the hook portion (2).
2. The moving spring leaf according to claim 1, characterized in that: The side of the flange (3) and the hook part (2) are integrally bent and formed, and the hook part (2) and the moving spring body (1) are integrally bent and formed.
3. The moving spring leaf according to claim 1, characterized in that: The bend connection between the flange (3) and the hook (2) is formed by rounding the corners to create a smooth flange corner structure.
4. The moving spring leaf according to claim 3, characterized in that: The radius of the rounded corner at the bend connection between the flange (3) and the hook (2) is ≥0.3mm.
5. The moving spring leaf according to claim 1, characterized in that: The hook portion (2) has a first bend portion (21) and a second bend portion (22). The first bend portion (21) is configured to be bent at approximately 90° to the free end of the moving spring body (1), and the second bend portion (22) is configured to be bent at approximately 90° to the end of the first bend portion (21).
6. The moving spring leaf according to claim 5, characterized in that: An opening (23) is provided at the bend connection between the first bend (21) and the second bend (22).
7. The moving spring leaf according to claim 6, characterized in that: The opening (23) is located at the middle position of the bend connection between the first bend (21) and the second bend (22).
8. The moving spring leaf according to claim 1, characterized in that: The moving spring is made of beryllium copper and has a thickness of 0.1mm to 0.15mm for the moving spring body (1), the hook part (2) and the flange (3).
9. The moving reed according to any one of claims 1 to 8, characterized in that: A flange (3) is provided on both sides of the hook part (2).
10. A force guided relay characterized by: Includes the movable spring as described in any one of claims 1 to 9.
