The clamping spring generally includes a connecting portion, a clamping portion, and a lead-out portion. The clamping portion and the lead-out portion are respectively provided on the connecting portion, and the connecting portion generally has a U shape. The clamping portion includes two spring plate clamps, and the two spring plate clamps are provided on opposite sides of the connecting portion. Such a clamping spring has the following deficiencies: when a pin is inserted between the two spring plate clamps of the clamping spring, the connecting portion of the clamping spring often shows a phenomenon of unilateral opening, resulting in unreliable contact between the clamping spring and the pin. In addition, the current-carrying cross-sectional area of such a clamping spring is small, resulting in a low allowable current and it cannot be applied to products with high load requirements.

In other embodiments, the lead-out portion is connected to the second support plate or the third support plate or the fourth support plate.

[0024] In this embodiment, the connecting portion 1, the clamping portion 2, and the lead-out portion 3 are formed by shearing and bending a same spring plate.

Thus, the first spring plate clamp 21 and the second spring plate clamp 22 respectively form a bilinear contact connection with the pins they clamp. Compared with the clamping spring in the prior art (which is a single linear contact connection), obviously, the clamping spring of the present invention has a more reliable contact with the pins.

[0025] In this embodiment, a first reinforcing rib 121 is provided on the outer side surface of the second support plate 12, and the first reinforcing rib 121 extends to a part of the third support plate 13 close to the second support plate 12; a second reinforcing rib 141 is provided on the outer side surface of the fourth support plate 14, and the second reinforcing rib 141 extends to a part of the third support plate 13 close to the fourth support plate 14. Specifically, the first reinforcing rib 121 is horizontally arranged and is located at the middle position of the outer side surfaces of the second support plate 12 and the third support plate 13. Similarly, the second reinforcing rib 141 is horizontally arranged and is located at the middle position of the outer side surfaces of the fourth support plate 14 and the third support plate 13.
