Abstract
Provided is a novel low voltage knife switch, comprising a pedestal, a cutter head, a fuse/sheet, a metal clamp, a wiring apparatus, and a compacting mechanism, wherein there are two sets of wiring apparatuses, with each set having three; one set is connected with the metal clamp while the other set is connected with the fuse/sheet, and one end of the wiring apparatus is a duckbilled elastic metal clamp, with the other end thereof being connected with the metal clamp and the fuse respectively via fastening screws respectivley. A fastener is composed of a metal shaft, three segments of insulating polygon prisms fixed upon the metal shaft, an insulating wrench arranged upon the metal shaft, and a polygonal fixed block arranged at one end of the metal shaft closer to the insulating wrench. The fastener is installed upon the pedestal via an installing hole arranged at one side of the pedestal and a polygonal fixing hole arranged at the other side of the pedestal. As the polygonal fixed block upon the fastener is provided with an eccentric rotating shaft and multiple planes, the fixed block loosens/presses the elastic metal sheet in the wiring apparatus when the wrench rotates upward/down, thereby facilitating joining and taking of the connecting line.
Description
Technical field
The utility model relates to a kind of Low voltage knife switch, and particularly a kind of convenience connects power line and makes power line that firm novel Low voltage knife switch is installed.
Background technology
The connector lug of existing Low voltage knife switch is to be made up of copper wiring hole and holding screw, and copper wiring hole is fixed on the ceramic base, when its installation, connection power line; Very bother; In addition, owing to the reason such as aging of the restriction of technology, materials used, running or the rust problem of waiting indefinitely often takes place between wiring hole and the holding screw; Be unfavorable for the connection and the replacing of power line, tend to have influence on normal electricity consumption.
Summary of the invention
To the weak point that prior art exists, the purpose of the utility model is to provide a kind of novel Low voltage knife switch, the power line connection of this plug-in strip, fastening very convenient quick, and be easy to safeguard.
The purpose of the utility model realizes through following technical proposals:
A kind of novel Low voltage knife switch comprises base, cutter head, fuse or sheet, metal clamps, termination and hold-down mechanism; Termination has two groups each three; One group continuous with metal clamps; Another group links to each other with fuse or sheet; Termination one end is a duckbill elastic metallic card, and the other end connects metal clamps and fuse respectively through holding screw, fastener by metal shaft, be fixed on the metal shaft the three sections polygon prisms of insulation, be arranged on the Insulation spanner on the metal shaft and be arranged on the metal shaft and form near the polygon fixed block of spanner one end.Fastener is installed on the base through installing hole and the opposite side polygon fixing hole that is arranged on base one side.
Further, described three sections polygon prisms of insulation that are arranged on the metal shaft are six prisms.
As preferably, vertical seamed edge of the polygon prism of described insulation is a fillet.
The beneficial effect of the utility model is: because the polygon fixed block on the fastener has eccentrically weighted shaft and a plurality of plane; So spanner upwards changes time-out; Fixed block unclamps the elastic sheet metal in the termination, and conveniently connect, get connecting line this moment, after spanner is depressed; Fixed block can compress elastic sheet metal and fix, and it is not tight to prevent that sheet metal from combining with connecting line.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model fastener structural representation.
Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the execution mode of the utility model is not limited thereto.
Embodiment
Like Fig. 1, shown in 2; A kind of novel Low voltage knife switch comprises base 1, cutter head 2, fuse or sheet 3, metal clamps 4, termination 5 and hold-down mechanism; Termination 5 has two groups each three; One group continuous with metal clamps 4, and another group links to each other with fuse or sheet 3, and termination 5 one ends are duckbill elastic metallic card 6; The other end connects metal clamps 4 and fuse or sheet 3 respectively through holding screw, fastener by metal shaft 7, be fixed on three sections insulation on the metal shaft 7 polygon prismatic 8, be arranged on the Insulation spanner 9 on the metal shaft 7 and be arranged on the metal shaft 7 and form near the polygon fixed block 10 of Insulation spanner 9 one ends.Fastener is installed on the base through installing hole and the opposite side polygon fixing hole that is arranged on base one side.
Further, described three sections insulation polygon prismatic 8 that are arranged on the metal shaft 7 are six prisms.
As preferably, vertical seamed edge of described insulation polygon prismatic 8 is a fillet.
In sum, through the description of present embodiment, can make present technique field personnel's better implement this programme.
