Abstract

The utility model relates to a fuse with indicating means which is composed of a socket with a display chamber and a flux chamber, an electrode plate fixed on the flux chamber, a display device electrically connected with the electrode plate, fixed on the display chamber, comprising a conductive strip, a resistor, a neon bulb, a puller spring, a display chamber upper cap with loopholes, at least two elastic flux contacts provided with springs and a flux whose both ends are respectively fixed with the flux contact. The upper cap is fixed with the socket by a ratchet buckling a detent; the upper cap is fastened on the socket; the flux contact is contacted with the puller of the electrode plate on the socket; the fuse protects the electric line of apparatus from overload of short-circuit. The fuse is characterized in that the fused flux can be discovered instantaneously, thus the fault is defecated quickly, and the fuse can centralization display and monitor.

Description

The display type fuse

The utility model relates to a kind of electric wiring and equipment short circuit or overload protection fuse.

The fuse that is used for electric wiring and electric equipment short circuit, overload protection, using maximum at present is plug-in fuse.And existing plug-in fuse does not all have display unit, can not carry out centralized monitor, this has brought difficulty for electrician's the work of patrolling and examining, the electric wiring of general process units and the fuse of various electric equipments etc. are to install concentratedly in switchboard, switch cubicle or control cubicle, search quite difficulty after the fused mass of fuse fusing, fix a breakdown and consume the long period, often bring adverse effect to ordinary production.

The purpose of this utility model provide a kind of have show the dress spring, can carry out centralized monitor, the display type fuse that can find immediately during fused mass of fuse fusing, fault can be got rid of rapidly.

The display type fuse is made of base, loam cake, melt, two battery lead plates having a wiring hole, base constitutes by having the melt chamber and the display room that cut off grid, have on the base side wall face into and out of the cable-through hole of lead and the ratchet of fixed cover, two battery lead plates that have wiring hole are fixed in the melt chamber.Display unit electrically connects the spring that holds out against that the other end and another conducting strip electrically connect and constitutes by being electrically connected resistance, neon bulb, an end and neon bulb that the other end and neon bulb electrically connect with a conducting strip with whole conducting strip, the end that is connected of two battery lead plates respectively, and display unit is fixed in the base display room.On be stamped display room loam cake and at least two the melt chamber loam cakes that have loophole, each melt chamber loam cake is equipped with two and has the telescopic melt contact of spring, the melt two ends are separately fixed on two contacts.Be stamped the connection ratchet on display room, the melt chamber, connect ratchet and cover by being hinged on its whole articulated jib that is connected.Connecting ratchet has goring push spring, connects ratchet and clamps the base side wall face ratchet pawl is colluded crouch in the ratchet slot on the base side wall face loam cake is fastened on base under the goring push spring effect.

For the ease of the centralized displaying and the monitoring of fuse, between the resistance of the display unit of display type fuse and neon bulb and hold out against external conducting strip is arranged between spring and neon bulb, on the base side wall face external socket is housed, external conducting strip and external socket electrode electrically connect.

Can neon bulb be lighted during display type fused mass of fuse fusing chamber and award demonstration, thereby can find fault rapidly and its eliminating.Utilize external plug the display unit neon bulb can be installed concentratedly and on the front panel of switchboard, switch cubicle, control cubicle, carry out centralized displaying and monitoring.Melt has two at least, and a fusing can be pressed other any one loam cakes and circuit or equipment be resumed operation the circuit connection rapidly.Simultaneously, also can press the loam cake of varying number according to instructions for use can be with in the melt place in circuit of varying number and then regulate and change the electrical load capacity of fuse.

Accompanying drawing is an embodiment of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.

Fig. 1 is a display type fuse base structure chart.

Fig. 2 is a display type fuse appearance assumption diagram.

Fig. 3 is the vertical view of Fig. 2.

Fig. 4 is the A-A cutaway view of Fig. 2.

As shown in the figure, the display type fuse goes out base (3), loam cake, melt (33), the battery lead plate (1) that has wiring hole, (5) formation, base constitutes by having the melt chamber (4) and the display room (15) that cut off grid (2), (17), the base side wall face is by the ratchet (28) that cable-through hole (6), (16) and fixed cover into and out of lead are arranged, and the battery lead plate that has wiring hole is fixed in the melt chamber.Display unit holds out against spring (8) formation by the resistance (13) that electrically connects with whole conducting strip (7), (14), an end and the conducting strip (14) that is connected of two battery lead plates respectively, neon bulb (11) that an end electrically connects by the external conducting strip (12) and the resistance other end, an end by what the external conducting strip (9) and the neon bulb other end electrically connected that the other end and conducting strip (7) electrically connect, and display unit is fixed in the base display room.External conducting strip electrically connects with the external socket electrode that is fixed on the base side wall face.On be stamped the display room loam cake (26) that has loophole (27) and two melt chamber loam cakes (20), (22), each melt chamber loam cake is equipped with two telescopic melt contacts (32) that have spring (31), fixedlys connected with two melt contacts respectively in the melt two ends.Be stamped connection ratchet (18), (19), (21), (23), (24), (25) on display room loam cake, the melt chamber, connect ratchet and cover by being hinged on its whole articulated jib (29) that is connected.Connecting ratchet has goring push spring (30), connects ratchet and clamps the base side wall face ratchet pawl is crouched loam cake is fastened on base in the ratchet teeth groove on the base side wall face under the goring push spring effect.

When using the display type fuse, the lead that will connect with electric wiring or electric equipment stretches in the base by cable-through hole and wire termination is fixed in the wiring hole of battery lead plate, fasten display room then with the melt chamber loam cake and the melt contact is held out against one of them melt chamber loam cake fastening to contact two battery lead plates, fuse promptly puts into operation.When electric wiring or equipment is short-circuited or two conducting strips of overload fuse melt when fusing display unit between produce voltage and neon bulb lighted, thereby can find immediately.After fault is got rid of another loam cake is pressed fuse and promptly put into operation, the loam cake goring push spring of extrusion melt fusing connects ratchet by deviating from the ratchet teeth groove to take off the melt that loam cake more renews, and is fastened on again after the replacing on the base as standby.Neon bulb concentrated be loaded on the front panel of switchboard, switch cubicle, control cubicle, will be connected plug that lead connects with neon bulb and be plugged on centralized displaying and the monitoring that to carry out the fuse operation on the socket on the fuse base.
