[0002] The existing contact finger plate of the disconnector is generally made of PBT plastic material. As the service time increases, the contact finger plate is prone to aging and breaking, causing the conductive roller to fall off, increasing the loop resistance between the left and right contact plates, causing the contact part to heat up, and the excessive temperature burns the remaining conductive roller, which in turn causes the disconnector to operate in a stuck state, and problems such as incomplete opening and closing. At the same time, due to the increase in service time, it will also cause internal water accumulation. The original contact finger plate is an integral structure that cannot be disassembled. When replacing it, the coupling needs to be disassembled. After the contact finger plate is replaced, the upper conductive teeth need to be re-hooked and adjusted. The maintenance cycle is long, time-consuming and labor-intensive, and seriously prolongs the power outage time.

[0003] In order to solve the above problems, a new type of metal assembled isolating switch contact finger plate is designed. It can be flexibly disassembled, does not need to lift the knife switch, does not need to adjust or hang the teeth, can be quickly replaced, and reduces power outage maintenance time. The contact finger plate is corrosion-resistant, has high mechanical strength, is not easy to deform, has a long maintenance cycle, and has high operating reliability. At the same time, it has a simple structure and is easy to operate, which greatly reduces costs. Summary of the invention

The assembled high-voltage disconnector conductive disk of the technical solution can be flexibly disassembled, without hoisting the knife switch, and without adjustment and hanging teeth, so that quick replacement can be achieved, reducing power outage maintenance time, and the contact finger disk is corrosion-resistant, has high mechanical strength, is not easy to deform, has a long maintenance cycle, and has high operating reliability. At the same time, it has a simple structure and is easy to operate, which greatly reduces the cost.

[0033] In this embodiment, the touch roller head includes a contact section 10 of a conical structure and a mounting section 9 of a cylindrical structure, and a mounting groove for mounting a guide seat is provided inside the cylindrical section; the touch roller head is a columnar structure as a whole, and a conical structure is adopted at the end to facilitate contact and installation with the rotating shaft, and a mounting groove is provided in the cylindrical section to facilitate adjustment of the position of the touch roller head after the touch roller head is installed.

[0034] In this embodiment, the guide seat includes a spring mounting platform 7 for mounting the spring 5 and a plug-in column 8 for use with the mounting groove. The spring mounting platform 7 and the plug-in column 8 are perpendicular to each other. The cross section of the guide seat is in a "T" shape as a whole. The plug-in column 8 is inserted into the mounting groove, which is convenient for adjusting the position and pressing the touch roller head. A circular groove 12 is provided on the top of the spring mounting platform 7. An insulating pad 6 made of non-metallic material is provided in the circular groove 12. The design of the circular groove 12 is convenient for installing the insulating pad 6. The insulating pad 6 is made of non-metallic materials such as rubber.
