[0016] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] This embodiment describes a terminal block for an online measurement error estimation device of a smart meter, comprising a vertical shell 1, a horizontal shell 2, a guide plate 3, a roller 4, a conductive plate 8, an insulating threaded rod 10, a groove rod 13, a slide rod 14, a locking mechanism, two pressing mechanisms and two sets of insulating rods 9;

[0018] The vertical shell 1 is connected and fixed with the transverse shell 2, and a locking mechanism is provided on the transverse shell 2. A guide plate 3 is provided in the transverse shell 2, and a roller 4 is rotatably provided on the guide plate 3. Two groups of insulating rods 9 are horizontally provided in the vertical shell 1, and each group of insulating rods 9 has two insulating rods 9. Both ends of each insulating rod 9 are fixedly connected to the inner wall of the vertical shell 1. The conductive plate 18 is slidably connected to the two groups of insulating rods 9. A clamping mechanism is provided between each group of insulating rods 9. Each of the clamping mechanisms is connected to the conductive plate 18, and the conductive plate 18 is threadedly connected to the insulating threaded rod 10. The insulating threaded rod 10 is located between the two clamping mechanisms, and one end of the insulating threaded rod 10 is rotatably connected to the inner wall of the vertical shell 1, and the other end of the insulating threaded rod 10 extends to the outside of the vertical shell 1, and one side of the outer wall of the vertical shell 1 is fixedly connected to the groove rod 13, and the other side of the outer wall of the vertical shell 1 is fixedly connected to the sliding rod 14.

[0019] The locking mechanism includes a pull rod 5, a spring 6 and a pressure plate 7;

[0020] The transverse shell 2 is provided with a sliding hole, and the lower end of the pull rod 5 slides through the sliding hole and is arranged in the transverse shell 2. The lower end of the pull rod 5 is fixedly connected to the pressure plate 7. The spring 6 is sleeved on the pull rod 5, one end of the spring 6 is fixedly connected to the inner wall of the transverse shell 2, and the other end of the spring 6 is fixedly connected to the pressure plate 7.

[0021] A plurality of thorns are evenly distributed on the lower end of the pressing plate 7 .

[0022] Each of the clamping mechanisms includes a conductive plate 11 and a spring 12;

[0023] One end of the conductive plate 11 is hinged to the conductive plate 8 , the inner wall of the conductive plate 11 is fixedly connected to the spring 12 , and the spring 12 is fixedly connected to the conductive plate 8 .

[0024] When using the utility model, first insert the signal line into the horizontal shell 2. By pulling the pull rod 5, the spring 6 is compressed, allowing the signal line to move toward the vertical shell 1 under the guidance of the guide plate 3. The design of the roller 4 allows the signal line to change direction more smoothly, reducing friction and damage. When the signal line moves between a set of insulating rods 9, the pull rod 5 is released, the spring 6 rebounds, and the pressure plate 7 moves downward, and the thorns on the pressure plate 7 contact the outer wall of the signal line, increasing the friction force, and realizing the initial fixation of the signal line.

[0025] Next, the wiring of the error estimation device is introduced into the vertical housing 1 and placed between another set of insulating rods 9. By rotating the insulating threaded rods 10, the conductive plate 1 8 slides on the insulating rods 9, and at the same time drives the clamping mechanism (composed of the conductive plate 2 11 and the spring 2 12) connected thereto to move in the direction of the wiring of the signal line and the error estimation device. The hinged design of the conductive plate 2 11 allows it to be adaptively adjusted according to the diameter of the signal line or wiring, while the spring 2 12 provides the necessary clamping force to ensure that the signal line and wiring form a stable electrical connection with the conductive plate 1 8.

[0026] When multiple devices are required to be connected in series or used in combination, the sliding rod 14 of one device can be inserted into the groove rod 13 of another device to achieve quick connection and fixation between the devices. This design not only simplifies the installation process, but also improves the overall stability and reliability of the system.

[0027] In summary, the utility model realizes fast and stable connection between signal lines and error estimation device wiring through ingenious mechanical design and electrical connection scheme, and has high flexibility and scalability, and is suitable for the application requirements of various smart meter online measurement error estimation systems.

Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalents of the claims be included in the present invention.
