Detailed Description
The utility model is further described with reference to the following detailed drawings in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the utility model easy to understand.
The switch cabinet modularized grounding switch provided by the utility model has the advantages that all parts of the grounding switch are connected to form a modularized whole, so that the structure is simple, and the assembly is convenient; meanwhile, the insulating screw rod is adopted to rotate to drive the movable contact to axially move forwards and backwards so as to reach a closing position and a separating position, and the use requirement of the grounding double-station is met.
Referring to fig. 1, an example of a switch cabinet modular grounding switch provided by the present utility model is shown.
As can be seen from the figure, the modularized grounding switch of the switch cabinet in the present example mainly includes five parts, namely a closing contact base 1, a contact tube 9, a grounding contact 10, a moving contact 6 and an insulating screw rod 8.
The switching-on contact seat 1 is connected with one end of a contact tube 9 through a moving contact 6, contacts 2 are respectively and fixedly connected with the switching-on contact seat 1 and the contact tube 9 on two sides of the moving contact 6, and the other end of the contact tube 9 is connected with a grounding contact seat 10.
Thus, one side of the grounding switch body 12 is formed, and both sides of the grounding switch body 12 are symmetrically arranged.
The insulating screw rod 8 is arranged in the middle of the grounding switch body 12, and one end of the insulating screw rod 8 is connected with a screw shaft 11 which is arranged in the middle of the two-side grounding seat 10.
The other end of the insulation screw rod 8 is fixedly connected with one end of the moving contact 6 through a screw rod nut 7, a thread matched with the screw rod nut 7 is arranged on the insulation screw rod 9, and the insulation screw rod 8 rotates to drive the screw rod nut 7 to move on the insulation screw rod 8 so as to drive the moving contact 6 to move forwards and backwards along the axial direction.
The junction of the closing contact seat 1 and the contact tube 9 is supported and fixed by the insulating supporting cylinder 3. The movable contact 6 is also provided with a guide key 4 which is matched with an insulating screw rod 8 to enable the movable contact to axially move forwards and backwards.
Therefore, the grounding switch body 12 is a modularized whole, the grounding switch assembly of the switch cabinet is completed as a whole assembly part, the installation and adjustment are not needed, and only the front end and the rear end of the grounding switch body 12 are assembled and fixed, so that the grounding switch is simple in structure and convenient to assemble.
