Abstract
The utility model provides a fuse base with indicating lamp, comprising a shell, cap nuts, electric poles and fuse and fuse holder set in the shell. The utility model is characterized in that it is provided with a resistor and a neon bulb with one end of the resistor and the fuse connected with the same electric pole and the other ends of them connected with the two poles of the neon bulb and that one end of the electric pole is connected with the circuit of the neon bulb and the fuse. When a fuse is fused, the neon bulb can light to indicate the repair person to ascertain the fused fuse, increasing the work efficiency and bringing convenience to the maintaining and checking person.
Description
The utility model is the fuse holder that is used for overload protection, is the improvement to existing fuse holder.
Widely used fuse holder is gone up by society at present, its formation is a pressed glass tube fuse in fuse holder and pressure cap, though using, the fuse holder of this formation is leveraged to the present for many years, but still exist an outstanding shortcoming, promptly in use can't whether fuse by the intuitive judgment fuse, need take off the cartridge fuse range estimation or use instrument detecting to judge, bring inconvenience for like this detection and maintenance, sometimes also error in judgement can appear, cause damage, in addition, because pressure cap and fuse holder junction do not have the sealing of waterproof, vapour, this also is a defective.
The purpose of this utility model is in order to solve the problem of above-mentioned existence, a kind of fuse holder of tape light to be provided.It can not need take off cartridge fuse or uses detecting instrument can judge just whether fuse fuses, and can be implemented in again in mist vapour and the water droplet environment and use.
In order to achieve the above object, the utility model comprises housing, nut, electrode, be contained in fuse, the fuse holder of housing inner chamber, it is characterized in that also having resistance and neon bulb, resistance one end and fuse one end coexist on the electrode, the other end of resistance and fuse is connected on the two poles of the earth of neon bulb, is connected another electrode between neon bulb and fuse.
For protection against the tide, water leakage has a lampshade and housing to fasten mutually the neon bulb is covered, and is provided with sealing ring at lampshade and housing, nut and housing junction.
In order to eliminate the cartridge fuse length tolerance, make between neon bulb and fuse and fuse and the electrode to be connected reliably, between neon bulb and fuse, be to rely on spring to be connected with tubular rivet.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a main cutaway view of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
(1) lampshade; (2) neon bulb; (3) sealing ring; (4) housing; (5) lamp socket; (6) sealing ring; (7) nut; (8) fuse holder; (9) lamp socket card; (10) resistance; (11) electrode; (12) fuse; (13) electrode; (14) insulation cushion; (15) tubular rivet; (16) spring.
Referring to Fig. 1, housing (4) interconnects by screw thread and sealing ring (6) is compressed with nut (7), fuse (12) is housed in the inner chamber body of housing (4), fuse holder (8), spring (16) is housed in the fuse holder (8), and spring (16) is pressed against fuse (12) on the electrode (11).Neon bulb (2) is contained in the lampshade (1), lampshade (1) is buckled in housing (4) goes up and sealing ring (3) is compressed.The indicator light circuit is: an end of resistance (10) is welded on the electrode (11); the other end is welded on the lamp socket card (9) that sticks lamp socket (5); the resistance of resistance (10) is between 120K Ω～200K Ω, and it plays the protective effect to neon bulb (2).One utmost point of neon bulb (2) is welded on the lamp socket (5), and another utmost point is welded on the tubular rivet (15) of riveted joint fuse holder (8), and fuse holder (8) is connected with electrode (13), thereby has formed the indicator light circuit.
The fuse circuit: electrode (11) has formed the fuse circuit by fuse (12) and fuse holder (8) and electrode (13).
Referring to Fig. 2, when fuse (12) was intact, electric current formed the loop through A → fuse (12) → B, and at this moment neon bulb (2) does not work.When fuse (12) fused, voltage was added in resistance (10) and neon bulb (2) two ends, makes neon bulb (2) build-up of luminance (between 90～250 volts of the starting voltages), thereby had played fuse (12) fusing indicative function.
The utlity model has following advantage: when 1, fuse (12) fused, neon bulb (2) was shinny, made the testing staff need not take off range estimation or the detection of use instrument, and it is quick and convenient to change fuse, has improved operating efficiency; 2, because the effect of sealing gasket (3), (6) can be worked it under the environment of steam droplet; 3, simple in structure, with low cost.
Claims (3)
1, a kind of fuse holder of tape light, it comprises housing (4), nut (7), electrode (11), (13), be contained in fuse (12), the fuse holder (8) of housing (4) inner chamber, it is characterized in that a resistance (10), neon bulb (2) in addition, resistance (10) one ends and fuse (12) one ends are with being connected on the electrode (11), their other end is connected on the two poles of the earth of neon bulb (2), and one of electrode (13) terminates between neon bulb (2) and the fuse (12).
2, the fuse holder of tape light according to claim 1, it is characterized in that having a lampshade (1) to fasten mutually neon bulb (2) is covered, be provided with sealing ring (3), (6) with housing (4) junction at lampshade (1) and housing (4), nut (7) with housing (4).
3, the fuse holder of tape light according to claim 1 and 2 is characterized in that being connected between neon bulb (2) and the fuse (12) is to rely on spring (16) and tubular rivet (15).
