Abstract
The utility model discloses a safety device for an alternating current line, mainly composed of a casing, a knob, a connecting terminal, a spring, a pallet, etc., wherein, a current fuse and a fuse link indicator are connected in parallel in the casing, the current fuse adopts a plurality of fuses radially fixed on an insulation disk, and the fuse link indicator is composed of a light emitting diode and more than one divider resistance which are connected in series. The utility model eliminates inconvenience of exchanging a fuse, trouble inspection is made to be easier, can be used when matching with a switch, a socket, etc., and can also be individually used. The utility model has the advantage of low cost.
Description
The utility model relates to the electricity consumption line protective devices, particularly alternating current electric line safeties.
The present alternating current transmission line safeties that use; be at installation insurance silk on the electric brake mostly or protective tube is housed on socket box; though played the certain protection effect; insurance bothers because it changes the outfit; and there is not a fuse melting indicating device; so be difficult for the reason that decision problem produces, cause the maintenance difficulty, cause fire incident because of wire short-circuiting easilier.
The purpose of this utility model is to provide a kind of insurance that changes the outfit simple, has the fuse melting indicating device, makes judgement, trouble shooting be easy to a kind of compound safety fuse.
The purpose of this utility model is to realize like this, a kind of compound safety fuse mainly is made up of shell, knob, binding post, spring, supporting plate etc., be characterized in having in the enclosure the electric current insurance and the fuse melting indicating device of parallel connection, the electric current insurance is to be radial being fixedly connected on the rotatable insulation disc surfaces with one heart by two above fuses, insurance also can be vertically fixed in the disk, and insurance is serially connected with on the circuit; The fuse melting indicating device is fixedly connected on two binding posts after being connected by light-emitting diode and an above divider resistance.
The utility model compared with prior art owing to adopt many to insure the electric current insurance of forming, makes and changes insurance simply; Fuse melting indicating device in parallel in the electric current insurance can accurately be indicated insurance break-make situation, makes trouble shooting more easy.
Below in conjunction with accompanying drawing a kind of compound safety fuse of the utility model is described further.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Fig. 3 is a line map of the present utility model.
A kind of compound safety fuse, the main shell of making by insulating material such as plastics 1, one insulation knob 2 is arranged on the shell 1, the conducting metal axle of knob 2 extend in the shell 1, binding post 3 is fixed on the side of shell 1, and run through shell 1 inside and outside, insulation disk 4 is housed on the axle of knob 2 from top to bottom successively, one binding post 3, spring 5 and supporting plate 6, and fix with nut, on disk 4, there are eight fuses 9 to fix in its surface, radially, an end of fuse 9 and a binding post 3 movable contacts, the other end contacts with the conducting metal axle of knob 2; The fuse melting indicating device by 8 series connection of an above divider resistance 7 and light-emitting diode after, two ends are connected on respectively on two binding posts 3, light-emitting diode 8 is fixed on the aperture on the shell 1, communicates with the external world.
Second embodiment of the present utility model, except that the position difference of six insurance installation forms of 9 and a binding post 3, remainder is all identical.The insurance 9 of present embodiment is the surface of vertical disk 4, is installed in the disk 4, and the two ends of insurance 9 contact with 3 activities of two binding posts respectively, form path.
When two binding posts 3 of the present utility model are serially connected with on the usefulness live wire of electric line, if line conditions is good, electric current will flow to electrical appliance by insuring 9, because divider resistance 7 resistances of fuse melting indicating device are very big, so electric current can not pass through, light-emitting diode 8 will be not luminous, and expression insurance 9 is good; When with faults such as electric line are short-circuited, insurance 9 will fuse, and this moment, electric current will be by the fuse melting indicating device, because the resistance of divider resistance 7 is very big,, make light-emitting diode 8 luminous so this moment, circuit only had weak current, show that insurance 9 has fused, need the maintenance electric line; After fault was got rid of, rotatable knob 2 inserted an other insurance 9 with on the electric line, forms good path, and electric current will make its whole circuit in running order once more by insurance 9.
Claims (3)
1, a kind of compound safety fuse mainly is made up of shell, knob, binding post, spring, supporting plate etc., it is characterized in that having in the shell electric current insurance and the fuse melting indicating device of parallel connection; The electric current insurance is to be radial being fixedly connected on the rotatable insulation disc surfaces with one heart by two above fuses, and only has a fuse to be serially connected with on the alternating current fire wire.
2, a kind of compound safety fuse according to claim 1 is characterized in that described electric current insurance is to be vertically fixed in the rotatable insulation disk to insure by two, and the insurance two ends contact with two binding posts are movable respectively.
3, a kind of compound safety fuse according to claim 1, it is characterized in that described fuse melting indicating device is by the above divider resistance series connection of light-emitting diode and after, be fixedly connected on two binding posts.
