Embodiment 2

[0032] Example 2, such as Figure 8 , Figure 9 Shown is a schematic diagram of the assembly structure of the insulating operating rod and the screw rod 13. A pin shaft 14 is provided at the end of the screw rod 13. One end of the pin shaft 14 protrudes from the end of the screw rod 13 and is inserted into the elastic conductive structure 6 In the card slot 61 at the front end of the contact on the top, and through the pin shaft 12 inserted in the radial direction of the metal end to ensure the anti-rotation cooperation between the screw rod and the insulating operating rod.

[0033] In other embodiments, the elastic conductive structure can be applied in other molded types of insulating operating rods.

[0034] In other embodiments, the accommodating hole may not be provided, and the elastic conductive structure may be directly arranged on the front end of the insulating operating rod; or it may be arranged on the outer peripheral surface of the metal end of the insulating o...

Abstract

The present invention relates to an insulated operating rod and a disconnecting switch with the insulating operating rod. The insulated operating rod comprises an operating rod body and a metal end head which is arranged at the front end of the operating rod body and is used for connecting the contact force transmitting component of the disconnecting switch; and the metal end head is provided with an elastic conductive structure which elastically contacts with the contact force transmitting component, and therefore, after the contact force transmitting component is connected with the insulating operating rod, reliable contact can be ensured under the elastic contact of the elastic conductive structure, and as a result, the generation of floating potential can be avoided, the insulating operating rod will not be ablated and carbonized, and the service life of the insulating operating rod can be prolonged.

Description

technical field [0001] The invention relates to an insulating operating rod and a disconnector with the insulating operating rod. Background technique [0002] The insulated operating rod is the core component of the isolating switch, one end of which is connected to the operating mechanism, and the other end is connected to the force transmission part of the contact, so as to realize the position change of the driving contact. The structure of the insulating operating rod in the prior art is as figure 1 As shown, it includes an insulating tube 1 with a hollow inside. The front and rear ends of the insulating tube 1 have metal ends, and the metal ends at the front end are connected to the screw rod that drives the moving contact of the isolating switch to move, and the screw rod constitutes the above-mentioned As for the force transmission part of the contact, the metal end at the rear end is connected with the operating mechanism, and the metal end includes an inner electr...
