Abstract
The utility model relates to a vacuum switch connecting device which is capable of effectively solving the problems that the connection between a moving contact of a vacuum switch and a conductive seat is complicated, the cost is high, the size is large, and therefore, the size of corresponding switch equipment is increased. According to the technical scheme, the vacuum switch connecting device comprises a vacuum arc-extinguishing chamber, a conductive seat and an insulating cylinder; the conductive seat and the vacuum arc-extinguishing chamber are installed in the insulating cylinder in sequence; a moving conductive rod of the vacuum arc-extinguishing chamber penetrates through a through hole in the center of the conductive seat; the moving conductive rod is provided with a spring contact finger contacted with the moving conductive rod; and an outer arc surface of the spring contact finger is contacted with the through hole wall in the center of the conductive seat. The vacuum switch connecting device is novel and unique in structure, simple and reasonable, small in size, easy to produce, low in cost, convenient to use and good in effect.
Description
Technical field
The utility model relates to a kind of vacuum switch jockey of vacuum switch moving conductive rod and conductive seat.
Background technology
The connected mode of vacuum switch moving contact and conductive seat mainly adopts and is flexible coupling at present; Be flexible coupling is to be made up of Copper Foil or cylinder litzendraht wire, the connected mode of it and conductive seat is: first with conductive clip, the moving conductive rod of vacuum interrupter is clamped, and then by being flexible coupling, conductive clip and outer wire outlet seat are linked together, the shortcoming of this connection is that connection is loaded down with trivial details, cost is high, and size is large, makes accordingly the volume of switchgear increase, therefore, its improvement and bring new ideas is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of vacuum switch jockey, vacuum switch moving contact can effectively be solved loaded down with trivial details with being connected of conductive seat, cost is high, and size is large, the problem that causes the volume that makes accordingly switchgear to increase.
The technical scheme that the utility model solves is, comprise vacuum interrupter, conductive seat and insulating cylinder, conductive seat and vacuum interrupter are housed in insulating cylinder successively, the moving conductive rod of vacuum interrupter passes from the through hole at conductive seat center, the spring touch finger contacting with it is housed on moving conductive rod, and the exterior arc surface of spring touch finger contacts with the through-hole wall at conductive seat center.
The utility model novel structure uniqueness, advantages of simple, volume is little, easily produces, and cost is low, easy to use, effective.
Accompanying drawing explanation
Fig. 1 is sectional front view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1, the utility model comprises vacuum interrupter, conductive seat and insulating cylinder, conductive seat 4 and vacuum interrupter 5 are housed in insulating cylinder 1 successively, the moving conductive rod 2 of vacuum interrupter 5 passes from the through hole 6 at conductive seat 4 centers, the spring touch finger 3 contacting with it is housed on moving conductive rod 2, and the exterior arc surface of spring touch finger 3 contacts with through hole 6 walls at conductive seat 4 centers.
In order to guarantee result of use, described spring touch finger 3 has 2 that are sleeved on side by side on moving conductive rod 2;
The diameter of described through hole 6 is greater than the diameter of moving conductive rod 2;
There is the arc groove corresponding with spring touch finger 3 described through hole 6 inner sides, and the exterior arc surface of spring touch finger 3 contacts with arc groove.
When the utility model uses, vacuum interrupter 5 is fixed in insulating cylinder 1, spring touch finger is directly contained in the through hole 6 of conductive seat 4, the moving conductive rod 2 of vacuum interrupter directly contacts with spring touch finger 3 by the external cylindrical surface of himself, the exterior arc surface of spring touch finger 3 contacts with the arc groove of conductive seat 4, so just realized being electrically connected of moving conductive rod 2 and conductive seat 4 by spring touch finger 3; Wherein, spring touch finger 3 also controlled watchband-shaped contactor replace; Compared with prior art, the utility model novel structure uniqueness, advantages of simple, volume is little, easily produces, and cost is low, easy to use, effective.
