[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 mounting groove 19 is fixedly connected with a control block II 113; the opposite surfaces of the control block II 113 and the control block I 38 are both provided with inclined surfaces, so that the control block II 113 can push the control block I 38 to move, so as to push the connecting plate 41 to move.

[0035] The side surface of the limiting plate 36 contacts the inner wall of the mounting groove 19. The rectangular limiting plate 36 limits the rotation of the cylinder 31.

[0036] When the control block I38 moves downward, the two ends of the U-shaped rod 35 are in contact with the conductive sheet II111 and the round rod 45 respectively. 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 are all capable of conducting electricity.

[0038] A method for using a terminal block for a station area topology equipment, the method comprising the following steps:

[0039] Step 1: Put the wire 6 and the conductive sheet I5 connected to the wire 6 onto the cylinder 44;

[0040] Step 2: Push the control block I 38 downward, so that the U-shaped rod 35 connects the conductive sheet II 111 with the round rod 45, and then connects the conductive sheet II 111 with the conductive sheet I 5, to test whether the device is in an abnormal state after the connection. If there is an abnormal state, release the control block I 38 to immediately disconnect the circuit and reduce damage to the device;

[0041] Step 3: After detecting that there is no abnormal state, push the door 11, and the door 11 drives the transmission rod 15 to move, and then drives the protrusion 16 to move, so that it drives the transmission block 25 to move, and the rotating drum 21 rotates accordingly, driving the cylinder 31 to move along the spiral groove 24 toward the direction of the rotating drum 21, and the limit plate 36 and the connecting plate 41 move accordingly, so that the conductive sheet I5 moves into the installation groove 19 until the control block I38 and the control block II113 are in contact, and the control block II113 pushes the control block I38 to move away from the control block II113 through the inclined surface, and pushes the connecting plate 41 to move, so that the conductive sheet I5 is close to the conductive sheet II111.

[0042] The working principle of the present invention is: when using the device, the wire 6 and the conductive sheet I5 connected to the wire 6 are sleeved on the cylinder 44;

[0043] Push the control block I38 downward, the control block I38 drives the slide plate 37 to move downward, and then drives the U-shaped rod 35 to move downward, so that the two ends of the U-shaped rod 35 connect the conductive sheet II111 with the round rod 45. Since the round rod 45 is in contact with the cylinder 44, and both are at a point, the conductive sheet II111 is connected with the conductive sheet I5 sleeved on the cylinder 44 to test whether the equipment is in an abnormal state after the connection. If there is an abnormal state, release the control block I38, and the U-shaped rod 35 moves to the original position under the elastic force of the spring 34, which can immediately disconnect the circuit and reduce damage to the equipment. At the same time, there is no need to remove the bolts, and the conductive sheet I5 can be directly removed from the cylinder 44 for inspection, which saves time and effectively avoids the occurrence of equipment damage caused by wrong wiring;

[0044] After detecting that there is no abnormal state, push the door 11, the door 11 drives the transmission rod 15 and the protrusion 16 to move into the equipment housing 1, so that the protrusion drives the transmission block 25 to move, and the rotating drum 21 rotates accordingly, and the rotation of the rotating drum 21 drives its spiral groove 24 to rotate. Since the limit plate 36 limits 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 drum 21, and the limit plate 36 and the connecting plate 41 move accordingly, and the connecting plate 41 drives the conductive sheet II 111 sleeved on the cylinder 44 to move, thereby moving the conductive sheet I5 into the installation groove 19. When moving, the control block I After 38 contacts with control block II 113, spring II 34 is stretched first until one end of the U-shaped rod 35 located inside the cylinder 31 contacts with the bottom wall of the groove 33, and 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 surface, and the control block I 38 pushes the connecting plate 41 to move, and the connecting plate 41 can move relative to the cylinder 44. During the movement of the connecting plate 41, the conductive sheet I5 will be pushed to move in the direction of the conductive sheet II 111, thereby making the conductive sheet I5 close to the conductive sheet II 111. After the door 11 is closed, the block 115 is embedded in 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 or removing the conductive sheet I 5, the limit plate 36 will scrape the surface of the conductive sheet II 111 to remove the attachments on the surface of the conductive sheet II 111 to reduce the attachments on the surface of the conductive sheet II 111 or the oxidation of the surface of the conductive sheet II 111, which may affect the power supply. After installation, the wire 6 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, which will affect subsequent use.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention.
