[0050] In each of the docking chambers 101, a spring piece 300 is disposed, the spring piece 300 has a spring arm 310, and the spring piece 300 extends towards the conductor 200 in the docking chamber 101. In the embodiment, a part of the spring piece 300 is embedded in the insulating base 100 and fixed to the insulating base 100, in each of the docking chambers 101, the conductor 200 and the spring piece 300 are oppositely arranged at two sides of the jack 102, and the spring arm 310 extends from one side of the jack 102 towards the conductor 200 across the central axis of the jack 102. In the embodiment, the aforementioned conductor 200 has a stop hook 210, and the stop hook 210 hooks the end of the spring arm 310 to block the spring arm 310 from swinging out of the jack 102, thereby defining one end point of the swing stroke of the spring arm 310.
[0051] Figure 2 is a perspective view of a slider of the terminal block of the utility model. Referring to Figure 2 , the slider 400 comprises a top pin 410 and a first hook 401. The top pin 410 and the first hook 401 are arranged at intervals to form a connecting channel 402 therebetween.
[0052] Figure 3 is a perspective view of a cam of the terminal block of the utility model. Referring to Figure 3 , the cam 500 is pivotally arranged in the insulating base 100, and the cam 500 has a second hook 502, a first push handle 510 and a second push handle 520.
[0053] Figure 4 is a perspective view of the terminal block of the utility model; Figure 5 is a front view of the terminal block of the utility model; Figure 6 is a schematic view of the initial state of the terminal block of the utility model in use; referring to Figures 4 to 6 , the slider 400 is movably arranged in the sliding groove 103, and the spring arm 310 of the spring piece 300 extends to the conductor 200 through the connecting channel 402. Therefore, the spring arm 310 cooperates with the stop hook 210 to limit the slider 400 from disengaging from the sliding groove 103. In the embodiment, the cam 500 and the spring arm 310 are arranged at the same side of the jack 102. Specifically, the first push handle 510 and the spring arm 310 are arranged at the same side of the jack 102 and oppositely arranged with the conductor 200, the first push handle 510 is arranged vertically upwards, and the spring arm 310 extends obliquely downwards; the second push handle 520 is arranged corresponding to the central axis of the jack 102 and extends across the central axis of the jack 102, and the second push handle 520 is arranged at the bottom of the docking chamber 101 and oppositely arranged with the jack 102.
[0054] The slider 400 can move into the docking chamber 101 so that the top pin 410 pushes against the spring arm 310, causing the spring piece 300 to elastically deform and push the spring arm 310 away from the conductor 200 to the first push handle 510. At the same time, the first hook 401 moves to the second hook 502 and is adjacent to the second hook 502. When the first push handle 510 is pushed by the spring piece 300 as described above, the cam 500 is simultaneously driven to rotate, thereby causing the second hook 502 to move toward the first hook 401 and hook the first hook 401, thereby fixing the slider 400 to resist the elastic force exerted on the slider 400 by the spring arm 310. At the same time, the slider 400 fixes the spring arm 310 in the position away from the insertion hole 102. When the second push handle 520 is pushed, it can drive the cam 500 to reverse and cause the second hook 502 to disengage from the first hook 401. The spring 300 returns to reset the spring arm 310. During the reset process of the spring arm 310, the slider 400 is pushed out of the docking chamber 101 and reset.
[0055] Figure 7 This is a schematic diagram showing the terminal block of this utility model in use, with the spring arm 310 retracted by the slider 400. (See attached diagram.) Figures 6 to 7 The terminal block of this utility model is used to connect to a wire 10. Before connecting the wire 10, the slider 400 is first moved as follows: Figure 6 The initial position shown is pushed down into the docking chamber 101 as if... Figure 7 The position shown. When slider 400 is in the position shown. Figure 7 When the slider 400 is in the indicated position, the top pin 410 pushes against the spring arm 310, causing the spring piece 300 to elastically deform, thereby pushing the spring arm 310 from the conductor 200 towards the first push handle 510. When the spring arm 310 abuts against the first push handle 510, the first hook 401 simultaneously moves to the second hook 502 and becomes adjacent to the second hook 502. In the aforementioned action, when the spring arm 310 presses against the first push handle 510, it simultaneously drives the cam 500 to move as shown in the figure. Figure 7 The view shown is rotated counterclockwise, which causes the second hook 502 to move toward the first hook 401 and hook the first hook 401.
[0056] Figure 8 This is a schematic diagram showing the slider 400 released from the cam 500 during use of the terminal block of this utility model. (See attached diagram) Figures 7 to 8 When the wire 10 is inserted into the docking chamber 101 through the socket 102 and presses against the second push handle 520, the cam 500 is driven to rotate clockwise, thereby causing the second hook 502 to disengage from the first hook 401.
[0057] Figure 9 This is a schematic diagram showing the docking state of the terminal block of this utility model during use. (See attached diagram.) Figures 8 to 9When the second claw 502 releases the first claw 401, the spring piece 300 returns to reset the spring arm 310 to press the conductor 10 to the conductor 200. The reset of the spring arm 310 simultaneously pushes the slider 400 out of the docking chamber 101 to reset the slider 400.
[0058] In summary, referring to Figures 6 to 9 The terminal block of the present application can retract the spring arm 310 by pressing the slider 400, which facilitates further insertion of the conductor 10. When the conductor 10 is inserted to the position, the spring arm 310 can be released by the conductor 10 touching the cam 500, and the spring arm 310 is reset to lock the conductor 10 and simultaneously reset the slider 400. Therefore, the terminal block of the present application does not need tools for wiring operation.
