Description
Technical field
The utility model relates to high-voltage electrical cabinet technical fields, and in particular to a kind of disconnecting switch moving contact component and it is lower go out
The connection structure of line seat.
Background technique
The word explanation of switch is to open and close.It refers to that one can make open circuit, make current interruptions or make it
Flow to the element of other circuits.The most common switch is the electromechanical equipment for allowing people to operate, wherein there is one or several contacts.Contact
" closed " (closed) indicate contact conducting, allow electric current flow through；" open circuit " (open) of switch indicates that contact is not turned on shape
At open circuit, electric current is not allowed to flow through.The developing history of switch is developed to from the original knife switch for needing manual hand manipulation
The present intelligent switch applied in various large electrics control equipment, the function of switch is more and more, and safety is also got over
Come higher, rotary switch is a kind of common switch, by the way that rotary operator to be locked in the spy with rotary operating device
The corresponding specific position of state is determined to prevent rotary operating device from being operated without permission.Rotary isolation switch is widely applied
In electric system, for example, photovoltaic, wind-powered electricity generation etc..Such as in photovoltaic system, the lesser electric current that is generated in each photovoltaic cell
It is combined in parallel so as to the electric current or general power needed for being provided using system.
Currently, common rotary separation switch includes an operating mechanism and several contact modules, in the contact module
Equipped with moving contact component, traditional moving contact component is riveted by two panels movable contact spring, and the movable contact spring is by conductive metallic material
It is made.When connection, for static contact between the movable contact spring of moving contact, movable contact spring bending clamps the stationary contact of static contact, when separating, moves
Contact overcomes resistance to leave static contact.Multiple division moving contact and static contact, the movable contact spring can be repeatedly bent, and conductive metal is dynamic
Contact occurs plastic deformation and changes so as to cause the spacing of two panels movable contact spring, poor contact when being easy to cause connection, seriously
Ablation contact.Meanwhile needing to overcome frictional force when the contact of two-piece type moving contact, the speed with disjunction can be reduced on, it is unfavorable
In quick disjunction with connect moving contact and static contact.In order to solve above-mentioned technical problem, conventional method is to disconnect position in mechanism
Set terminal is arranged metal parts and attracts plasma-arc, to extinguish electric arc；Or intensity and thickening material by reinforcing part
Plastic deformation and the big technological deficiency of frictional force are solved, but this conventional solution will increase the volume of switch, increase
Add the cost of product.
In addition, between existing moving contact component and lower wire outlet seat be attached by copper rod, frame mode is,
Screw thread is respectively set in the both ends of copper rod, opens up threaded hole on lower wire outlet seat, and threaded hole is opened up on moving contact component, installation
When, one end of copper rod is threadedly coupled with the threaded hole of moving contact component first, lower wire outlet seat and copper rod are then subjected to screw thread again
Connection, however, after copper rod and moving contact component fastening, since copper rod is already bent into type, the position of the copper rod other end
Specified place generally can not be reached, although can be attached by the way of rotating lower wire outlet seat with copper rod, with
After lower wire outlet seat is attached, due to being three-phase outlet, three lower wire outlet seats cannot cause only in the same horizontal position
Three lower wire outlet seats can be made to be located in the same horizontal position by way of making copper rod modification, such connection structure is during installation
It is not only time-consuming and laborious, but also have the hidden danger of damage copper rod.
Summary of the invention
The purpose of the utility model is to provide the connection structure of a kind of disconnecting switch moving contact component and lower wire outlet seat, this realities
With it is novel have the advantages that it is easy for installation.
Realize that the technical solution of above-mentioned purpose is as follows:
The connection structure of disconnecting switch moving contact component and lower wire outlet seat, including disconnecting switch moving contact component, copper rod with
And lower wire outlet seat, the disconnecting switch moving contact component are equipped with the first screw hole, lower wire outlet seat is equipped with the second screw hole, copper rod
One end is equipped with external screw thread, and copper rod is equipped with externally threaded one end and extend into the second screw hole on lower wire outlet seat and lower wire outlet seat screw thread
Connection, further includes screw, and the other end of the copper rod is equipped with first through hole, one end of the screw pass through after first through hole with every
It is after being threadedly coupled from the first screw hole on switch moving contact head component, the other end of copper rod and disconnecting switch moving contact component is tight
Gu.
Using such connection structure, after first the other end of copper rod and disconnecting switch moving contact component can be fastened, then
One end of copper rod and lower wire outlet seat are attached.After the other end and disconnecting switch the moving contact component fastening of copper rod, copper
The position of stick one end is positioned, in this way, for one end of multiple (three-phase outlet) copper rods, their position can be with
Positioned at sustained height, therefore, after these copper rods and the fastening of disconnecting switch moving contact component, will not deform, it is clear that such
It is time saving and energy saving and very convenient that structure has the advantages that installation.
