The insulator can fix, isolate and support the electrodes, avoiding dangerous situations such as short circuit and leakage between the electrodes. It is an important component of preventing electric shock and leakage in high-voltage electrical equipment. The corresponding two insulators of the meter box have different arrangement directions and relative positions. The two insulators are connected by a connecting plate or a knife plate.

[0003] In order to ensure that the connecting plate stably connects the two insulators, the two insulators are arranged side by side as much as possible to ensure that after the end of the connecting plate and the insulator joint are inserted, the end of the connecting plate and the top surface of the insulator fit together, making it easier for the nut to lock and fix the connecting plate. However, due to the limitations of the line layout or the space conditions of the meter box itself, one of the two corresponding insulators sometimes needs to be tilted, that is, a fixed plate is tilted in the meter box, the insulator is installed on it, and then the connecting plate is used to connect it to the corresponding insulator. However, it was found in actual assembly that due to errors, it is difficult to ensure the position accuracy of the insulator after installation, which is not convenient for the installation of the connecting plate, affecting the instability of the installation of the connecting plate.
