Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] EMBODIMENT

[0042] In conjunction with Figures 1 to 12 As shown in the drawings, the present embodiment provides a wire clamp capable of rapid wiring, having an insertion side for inserting the end of a conductor, the wire clamp comprising a fixed support 1 and a clamping spring 2 movably connected to the fixed support; the fixed support 1 is provided with a first support part 12 and a second support part 13; the clamping spring 2 is provided with a rotating part 9 disposed between the first support part 12 and the second support part 13; the rotating part 9 is provided with a first flip trajectory 7 cooperating with the first support part 12 and a second flip trajectory 8 cooperating with the second support part 13;

[0043] When the clamping spring 2 is turned down, the clamping spring 2 is slidably turned under the action of the first turning track 7 and the first support part 12 to reach the closed state; when the clamping spring 2 is turned up, the clamping spring 2 is slidably turned under the action of the second turning track 8 and the second support part 13 to reach the open state.

[0044] In the embodiment, the clamping spring 2 and the fixed bracket 1 are integrally punched and bent from a metal plate. Specifically, as shown in Figures 6 to 8 The two sides of the operating leg 5 are stamped and downwardly bent to form the rotating part 9, the movable groove 6 is arranged on the side of the rotating part 9 close to the insertion side E, and the upper end of the movable groove 6 away from the insertion side E is provided with a gap 10, so that the rotating part 9 is similar to a hook shape. In the embodiment, the inner wall surface and the outer wall surface of the movable groove 6 close to the insertion side E form the first turning track 7 and the second turning track 8. As shown in Figure 4 and Figure 5 The fixed bracket 1 is connected to the two side walls of the contact section 3 and outwardly bent to form a hollow support ear 11, which can be assembled with the movable groove 6 through the gap 10. The upper part of the support ear 11 is configured as the first support part 12 capable of cooperating with the first turning track 7; the lower part of the support ear 11 is configured as the second support part 13 capable of cooperating with the second turning track 8.

[0045] As shown in Figures 1 to 3As shown, through the arrangement of the first flipping trajectory 7, the second flipping trajectory 8, the first support portion 12, and the second support portion 13, the clamping spring 2 does not have a fixed pivot axis during the flipping process. Specifically, when the clamping spring 2 flips outward to open, the second flipping trajectory 8 approaches and abuts against the second support portion 13, while the first support portion 12 moves away from the first flipping trajectory 7 within the movable groove 6. At this time, during the flipping process, the second flipping trajectory 8 slides along the second support portion 13, that is, the second flipping trajectory 8 slides on the second support portion 13, simultaneously realizing the flipping action of the clamping spring 2. This makes the flipping force of the operating leg 5 acting on the clamping spring 2 gradually lighter as the angle between the operating leg 5 and the contact portion 3 of the fixed bracket 1 increases. That is, after the operating leg is initially flipped up in the closed state, it can be easily flipped later, realizing effortless flipping to open the clamping spring 2. When the clamping spring 2 flips inward to close, the first support part 12 approaches and abuts against the first flipping trajectory 7 in the movable groove 6; the second flipping trajectory 8 moves away from the second support part 13. At this time, during the flipping process, the first flipping trajectory 7 slides along the first support part 12, that is, the first flipping trajectory 7 slides on the first support part 12, and simultaneously realizes the flipping action of the clamping spring 2, so that the locking force of the clamping leg 4 when closed can increase rapidly as the angle between the operating leg 5 and the contact section 3 decreases, thereby increasing the locking force on the conductor end and improving the firmness of locking the conductor end.

[0046] In this embodiment, as Figures 8 to 12 As shown, the clamping spring 2 includes two clamping legs 4 arranged side by side, and a handle 14 attached to the operating leg 5.

The handle 14 is provided with two fixing portions 17; the two fixing portions 17 are respectively located within the first bent portion 15 and the second bent portion 16. Specifically, the two fixing portions 17 extend from a lower sidewall of the handle 14 along the width direction, and can be inserted into the first bent portion 15 and the second bent portion 16 from one side; and the handle 14, away from the sidewall and on one of its fixing portions 17, is provided with limiting protrusions 18 for limiting the clamping leg 4 in the width direction, preventing the clamping spring 2 from detaching from the handle 14.
