[0002] Most of the common wiring terminals on the market at present are fixed one by one with conductive sheets and wires through bolts during use. Although the structure is simple, in actual use, the bolts of the device equipped with the wiring terminal are likely to become loose after being vibrated, and then the conductive sheets are loosely connected, resulting in unstable power supply. In addition, the conductive sheets on the wiring terminal are easily affected by humidity, temperature, etc. in the surrounding environment, leading to surface oxidation, which will also affect the normal power supply. Therefore, improvements are made to it. Summary of the Invention

[0028] The fixing device 4 includes a connecting plate 41; a T-shaped slider 48 is fixedly connected to the upper end of the connecting plate 41, and the T-shaped slider 48 is slidably matched with the T-shaped slide groove 39 at the lower end of the limiting plate 36; a circular hole 46 is provided on the side of the connecting plate 41 away from the door 11, a round rod 45 is fixedly connected in the circular hole 46, and a cylinder 44 slidably matched with the circular rod 45 is sleeved on the outer side of the circular rod 45; a spring Ⅰ47 is fixedly connected between the cylinder 44 and the inner wall of the circular hole 46; a conductive sheet Ⅰ5 connected to the wire 6 is sleeved on the outer side of the cylinder 44;

[0029] A conductive sheet II 111 is fixedly connected to the inner wall of the installation slot 19. As the door 11 is closed, the wire 6 and the conductive sheet I5 can be driven to move into the installation slot 19 until the conductive sheet I5 contacts the conductive sheet II 111. In addition, multiple transmission rods 15 are provided on the door 11, so that multiple wires 6 can be installed at the same time to improve the installation efficiency. During the installation process, the limit plate 36 will scrape the conductive sheet II 111 when moving in the installation slot 19 to remove the attachments or oxide layer on the surface of the conductive sheet II 111 to ensure power supply.

[0030] A groove 33 is provided on the side of the cylinder 31; a U-shaped rod 35 is provided in the groove 33 and can slide up and down along the length direction of the groove 33, and a spring II 34 is fixedly connected between the top wall of the groove 33 and the U-shaped rod 35; the other end of the U-shaped rod 35 passes through a limit plate 36, the groove 33 is arranged below the limit plate 36, and a slide plate 37 is fixedly connected to one end of the U-shaped rod 35 below the limit plate 36; a through hole is provided on the slide plate 37, and a control block I 38 that slidably cooperates with it is provided in the through hole.

The U-shaped rod 35 is driven to move by the control block I 38, so that the line connection test can be performed without installing the conductive sheet I 5 to the working position, so as to facilitate replacement and save time.

[0032] The width of the control block I38 is greater than the width of the slideway II43, so as to prevent the control block I38 from sliding into the slideway II43 when pushing the connecting plate 41 to move, thereby affecting the clamping of the conductive sheet I5 by the connecting plate 41 and the inner wall of the mounting groove 19.

[0033] A card slot 17 is provided on both sides of the groove 12, and a slidable push block 114 is also provided on the equipment housing 1; a slide rail 116 is provided on both sides of the door 11, and a spring III 117 and a card block 115 that slidably cooperates with the slide rail 116 and the card slot 17 are fixedly connected inside the slide rail 116.

[0034] The bottom end of the inner wall of the installation groove 19 is fixedly connected with a control block II 113; inclined surfaces are provided on the opposite surfaces of the control block II 113 and the control block I 38. This facilitates the control block II 113 to push the control block I 38 to move, so as to facilitate the pushing of the connecting plate 41 to move.

[0035] The side surface of the limiting plate 36 contacts the inner wall of the installation groove 19. The rotation of the cylinder 31 is restricted by the rectangular limiting plate 36.

[0036] When the control block I 38 moves downward, the two ends of the U-shaped rod 35 respectively contact the conductive sheet II 111 and the round rod 45. An insulating layer is provided on the outer side of the U-shaped rod 35.

[0037] The U-shaped rod 35, the round rod 45, and the cylinder 44 can all conduct electricity.

[0038] A usage method of a wiring terminal for a substation topology device, the usage method includes the following steps:

[0039] Step 1: Sleeve the wire 6 and the conductive sheet I 5 connected to the wire 6 on the cylinder 44;

[0040] Step 2: Push the control block I 38 downward to connect the conductive sheet II 111 and the round rod 45 through the U-shaped rod 35, and further connect the conductive sheet II 111 and the conductive sheet I 5, so as to test whether there is an abnormal state of the device after connection. If there is an abnormal state, release the control block I 38, and the circuit can be immediately disconnected to reduce damage to the device;

[0041] Step 3: After detecting no abnormal state, push the door 11, the door 11 drives the transmission rod 15 to move, and further drives the convex block 16 to move, so that it drives the transmission block 25 to move, the rotating cylinder 21 rotates accordingly, drives the cylinder 31 to move along the spiral groove 24 towards the direction of the rotating cylinder 21, the limiting plate 36 and the connecting plate 41 move accordingly, and further moves the conductive sheet I 5 into the installation groove 19 until the control block I 38 and the control block II 113 contact. The control block II 113 pushes the control block I 38 to move away from the control block II 113 through the inclined surface, pushes the connecting plate 41 to move, and further makes the conductive sheet I 5 closely adhere to the conductive sheet II 111.

[0042] The working principle of the present invention is: when using this device, sleeve the wire 6 and the conductive sheet I 5 connected to the wire 6 on the cylinder 44;

[0043] Push down the control block I 38. The control block I 38 drives the slide plate 37 to move downward, and then drives the U-shaped rod 35 to move downward accordingly, so that both ends of the U-shaped rod 35 connect the conductive sheet II 111 with the round rod 45. Since the round rod 45 contacts the cylinder 44 and both are conductive, the conductive sheet II 111 is further connected to the conductive sheet I 5 sleeved on the cylinder 44 to test whether there is an abnormal state in the device after connection. If there is an abnormal state, release the control block I 38. Under the elastic force of the spring II 34, the U-shaped rod 35 moves to its original position, and the circuit can be immediately disconnected, reducing damage to the device. At the same time, without disassembling the bolts, the conductive sheet I 5 can be directly removed from the cylinder 44 for inspection, saving more time and effectively avoiding the situation of device damage caused by wrong wiring connection;

[0044] After detecting no abnormal state, push the door 11. The door 11 drives the transmission rod 15 and the convex block 16 to move into the device housing 1, so that the convex block drives the transmission block 25 to move, and the rotating cylinder 21 rotates accordingly. The rotation of the rotating cylinder 21 drives its spiral groove 24 to rotate. Since the limiting plate 36 restricts the rotation of the cylinder 31, the rotation of the spiral groove 24 will drive the cylinder 31 to move along the spiral groove 24 in the direction of the rotating cylinder 21, and the limiting plate 36 and the connecting plate 41 move accordingly. The connecting plate 41 drives the conductive sheet II 111 sleeved on the cylinder 44 to move, and then moves the conductive sheet I 5 into the installation groove 19. During the movement, after the control block I 38 contacts the control block II 113, the spring II 34 is first stretched until the end of the U-shaped rod 35 inside the cylinder 31 contacts the bottom wall of the groove 33. The other end of the U-shaped rod 35 passes over the position of the round rod 45. As the movement continues, the control block II 113 pushes the control block I 38 to move away from the control block II 113 through the inclined plane. The control block I 38 pushes the connecting plate 41 to move. The connecting plate 41 can move relative to the cylinder 44. During the movement of the connecting plate 41, it will push the conductive sheet I 5 to move in the direction of the conductive sheet II 111, and then make the conductive sheet I 5 closely adhere to the conductive sheet II 111. After the door 11 is closed, the latch 115 is inserted into the card slot 17 to prevent the door 11 from opening and causing the conductive sheet II 111 to separate from the conductive sheet I 5. At the same time, when installing and disassembling the conductive sheet I 5, the limiting plate 36 will scrape on the surface of the conductive sheet II 111 to scrape off the attachments on the surface of the conductive sheet II 111, so as to reduce the influence on power supply caused by the attachments on the surface of the conductive sheet II 111 or the oxidation of the surface of the conductive sheet II 111. After the wire 6 is installed, it will be embedded in the wire groove 112 at the bottom of the installation groove 19 to prevent the wire 6 from being squeezed and deformed, affecting subsequent use.
