Abstract
The utility model relates to a safe switch with fuse, which is composed of a switch seat, a switch, a fuse placement seat, a porcelain tubular fuse, a pin shaft and a terminal post. The key point of the utility model is that the bucket fuse placement seat is arranged in a common wall type switch and is fixed on the switch seat by the pin shaft, and the fuse is inserted into a hole of the fuse placement seat. The utility model has the advantages of simple structure, beautiful appearance, no space usage, safety, convenience and energy saving, and effectively prevent the accident occurring.
Description
The utility model relates to the appliance switch field, is specially band fuse type safety switch.
At present; the multiple combination alternating current-direct current low-voltage electrical apparatus control system that use in places such as communal facility, hotel, public place of entertainment, family; room generation overload must adopt unified overload protection means to many rooms, multi objective control, in case can influence the whole system outage or catch fire.The electrical equipment of most switch controls does not have overload protection.Even adopt frequently break-make of its power supply of Fuse switch, and must cut off the power supply during the fusible link in the replacing Fuse switch, coefficient of safety is low.
The purpose of this utility model provides a kind of band fuse type safety switch, and it has solved the frequent switching problem of power supply, can reach 0-20A according to the different Control current of fuse size.Fuse can with several switch combinations, control the on/off of a plurality of electrical equipment simultaneously, make several appointment electrical equipment targets play modular overload protective function, in case take place that overload can not cause that whole system outage and large tracts of land are caught fire etc.Can not cut off the power supply when changing fuse,
The utility model is achieved through the following technical solutions, band fuse type safety switch, it is made up of switch base, switch, fuse placement rack, porcelain tube formula fuse, bearing pin, terminals, its main points are that a bucket type fuse placement rack is installed in Wall-type switch commonly used, placement rack and switch base are fixed on the switch base with bearing pin, and fuse inserts in the placement rack hole.Contact is inlayed in its fuse placement rack bottom.Reed-type tack picks out end and fuse, fuse and contact, incoming end and contact are plane contact.The header board of its fuse placement rack and the header board of switch are arranged in parallel.Fuse is when reaching the overload rating electric current, and fusible link fuses in the fuse, and the electrical equipment of controlling by switch cuts off the power supply immediately.
The utility model has the advantages that simple in structure, easy, the good looking appearance of mounting or dismounting does not take up room, safe ready, energy savings effectively prevent the generation of contingency.
With reference to the accompanying drawings the utility model is elaborated.
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is a Facad structure schematic diagram of the present utility model;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is an electric circuit diagram of the present utility model.
Among the figure, the 1st, switch base, the 2nd, fuse picks out end, and the 3rd, porcelain tube formula fuse, the 4th, the fuse incoming end, the 5th, contact, the 6th, bearing pin, the 7th, the fuse placement rack, the 8th, switch, the 9th, switch picks out end, and the 10th, the switch incoming end.
Band fuse type safety switch, it by switch base 1, switch 8, fuse placement rack 7, porcelain tube formula fuse 3, bearing pin 6, fuse pick out end 2, fuse incoming end 4 forms, its main points are on Wall-type switch 8 left sides commonly used one bucket type fuse placement rack 7 to be installed, placement rack 7 is fixed on the switch base 1 with switch base 1 usefulness bearing pin 6, and fuse 8 inserts in placement rack 7 holes.Contact 5 is inlayed in fuse placement rack 7 bottoms.Reed-type tack picks out end 2 and is plane contact with contact 5, incoming end 4 with contact 5 with fuse 3, fuse 3.The header board of the header board of fuse placement rack 7 and switch 8 is arranged in parallel.Fuse 3 is when reaching the overload rating electric current, and fusible link fuses in the fuse 3, and the electrical equipment of controlling by switch cuts off the power supply immediately.During use, the live wire of two-phase electricity is cascaded switch and fuse by the utility model back panel wiring, insert electrical equipment then, in case overload or electric shock leaky take place, fuse disconnects, the Be Controlled appliance cut-off, as long as pull open bucket type fuse placement rack 7 outer being threaded to about 90 degree with hand, the porcelain tube formula fuse that extraction burns out, insert new fuse close the placement rack of fuse can be again to electric power supply, the daily Push And Release of appliances power source can be realized by master cock 8.
