Abstract
The utility model provides a novel pole switch comprising a base plate, an arc-extinguish chamber, a rotating disc, a draw bar, an indicator, a fixed contact, a moving contact, pole plates and clamping-type contacts, wherein the rotating disc, the draw bar and the indicator constitute a transmission mechanism; the draw bar is in rotational connection with the rotating disc; the fixed contact, the clamping-type contacts, the pole plate, the moving contact and a handle constitute a pole switch mechanism arranged in the middle position of the entire product; the handle is connected with the three pole plates arranged side by side in an integrated manner; the three pairs of clamping-type contacts and the arc-extinguish chamber are connected with an insulating pad plate and mounted on the base plate; the three pairs of clamping-type contacts corresponding to the three pole plates are located between the fixed contact and the moving contact; each clamping-type contact is provided with a boss corresponding to the top part of the pole plate; and the fixed contact is in pin joint with one end of the pole plate in a way that the pole plate can be opened or connected by rotating the pole plate around the pin in a fan-shaped manner, and the other end of the pole plate is electrically connected with the moving contact, in which a catch device is arranged to get the pole plate locked.
Description
Technical field:
The utility model relates to a kind of device for switching, is specifically related to a kind of novel knife switch of construction of switch.
Background technology:
Knife switch electrical equipment is that people's power supply commonly used in producing, living connects facility, and it is relatively simple for structure, but people often ignore its safety in utilization.Such as the disconnecting link switch safety guard is not set, makes outside electrical connections is exposed to; Though some knife switch is provided with sluice cover, but because sluice cover is divided into upper and lower two joints, and respectively with bolt on cutter hub, and along with people's use, often cause losing or forgetting installation of part sluice cover, can not fall automatically after the safety plate fusing, the fault point is difficult for being found, become the hidden danger on the safety, be easy to generate electric shock accidents.
The utility model content:
At the technical deficiency of existing the said goods, the purpose of this utility model is to provide a kind of novel knife switch, and it is by negative, arc control device, rotating disk, draw bar, indication piece, fixed contact, moving contact, knife plate, form folder type contact etc.
The technical scheme that its technical problem that solves the utility model adopts is: transmission mechanism is that rotating disk, draw bar and indication piece are formed, and draw bar connects dial rotation; Disconnecting link mechanism is the centre position in integral product, is made up of fixed contact, knife plate, folder type contact, moving contact, handgrip.Three knife plates side by side of the unified connection of handgrip, three pairs of folder type contacts are connected insulating pad and are contained on the negative with arc control device, three pairs of folder type contacts are corresponding with three knife plates, and folder type contact is positioned in the middle of fixed contact and the moving contact, and the corresponding knife plate of every folder type contact top is provided with projection.Fixed contact is connected with knife plate one end hinge pin, and knife plate can be fan-shaped along the hinge pin rotation to be opened or connect, and the other end of knife plate is connected energising with moving contact, establish the grab device in the moving contact, blocks knife plate.
The beneficial effects of the utility model are: two-way control, reduction overvoltage electric current or strong lightning strike, protective current steady operation, and saves energy.
Description of drawings:
Fig. 1 is a product overall structure schematic diagram, and Fig. 2 is product component-transmission mechanism schematic diagram, among the figure, and 1, negative 2, arc control device 3, rotating disk 4, draw bar 5 indication pieces 6, fixed contact 7, moving contact 8, knife plate 9, folder type contact
Embodiment:
Shown in Fig. 1 and 2, a kind of novel knife switch, rotating disk 3, draw bar 4 and indication piece 5 are combined into transmission mechanism, and rotating disk 3 connects draw bar 4 and determines to move by indication piece 5; Forming disconnecting link mechanism by fixed contact 6, knife plate 8, moving contact 7, folder type contact 9, handgrip, is the reseting movement structure that swings up and down, in the centre position of integral product.Knife plate 8 has three to unify the connection activity by handgrip side by side, the three pairs of folder type contacts 9 and arc control device 2 are contained on the negative 1 by insulating pad, eliminated the harm of arcing, three pairs of folder type contacts are corresponding with three knife plates, folder type contact 9 is positioned in the middle of fixed contact 6 and the moving contact 7, every folder type contact 9 corresponding knife plates 8 tops are provided with projection, guarantee that knife plate 8 clutches are accurate.Fixed contact 6 is connected with knife plate 8 one end hinge pins, knife plate 8 can be fan-shaped along the hinge pin rotation and open or connect, the other end of knife plate 8 is connected energising with moving contact 7, moving contact 7 adopts and directly compresses mode, establishes the grab device in the moving contact 7, blocks knife plate 8, guarantee stability and safety, electric conductivity strengthens, and uses operating maintenance convenient, and the life-span is long.
