Abstract
The utility model relates to a fuse overcurrent protector for distributing equipment, which is composed of pins, an upper cover, a lower cover, a fuse, and an alarm circuit. The utility model adopts photosensitive elements and triggers the alarm circuit by utilizing the light signals generated by the fuse failure. The utility model has the advantages of small size, simple structure and reliable alarm. The fault of a telephone set can be discovered quickly by using the utility model.
Description
The utility model relates to the equipment that distributing frame is used, particularly a kind of fuse overcurrent protector.
Existing distributing frame overcurrent protector; generally only on pin, connect fusible link; when over-current phenomenon avoidance occurs; fuse failure is with protection switch and telephone set; but because common overcurrent protector does not send the warning message of fuse failure; fault can not be found immediately, can only wait for user's inquiry, just finds out the overcurrent protector that breaks down and is changed.Although also there are some to have the overcurrent protector that sends warning message; but they are mainly reported to the police with mechanical type; not only cause overcurrent protector internal structure complexity, member various; and the transmission performance of mechanical component is different, member is small and exquisite, processing is expensive; also must carefully transport, assemble, otherwise be easy to generate false alarm or malfunctioning.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, the fuse overcurrent protector that provides a kind of flash of light simple in structure, that utilize fuse failure moment generation to use as the distribution plant of warning triggering signal.
The purpose of this utility model is achieved by the following technical solution; the fuse overcurrent protector that distribution plant is used; constitute by pin, loam cake, lower cover, the fuse that is connected with pin and warning circuit; special feature is near fuse; storing has the light-sensitive element of the light signal that sends when being enough to respond to fuse failure, and the signal that light-sensitive element produces is as the triggering signal of warning circuit.When not having overcurrent, fuse does not send light signal, and light-sensitive element does not then produce signal, and whole warning circuit is in the lock state; When producing overcurrent, fuse is fusing in a single day, and its flash of light of sending makes light-sensitive element produce triggering signal, triggers the warning circuit action.
As seen by above-mentioned, the utility model adopts fuse, the light-sensitive element trigger switch as warning circuit, and is simple in structure small and exquisite, and it is reliable to report to the police, and is difficult for taking place false alarm; In addition, need not external power supply, the power consumption of warning circuit normality seldom can realize that faults itself shows, for row's barrier rapidly provides convenience.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the C-C cutaway view of Fig. 1;
Fig. 3 is the schematic diagram of alarm trigger circuit.
Below in conjunction with drawings and Examples the utility model is further elaborated.
See figures.1.and.2, the rear portion of present embodiment pin 1 is the wiring board of warning circuit 3, its all elements all are packaged in loam cake 8 and the lower cover 2, and putting between two fuses 4 that are connected with pin 1 has a light-sensitive element 5, the light signal that sends when being used to respond to fuse 4 fusing.Light-sensitive element 5 is formed optical trigger (as shown in Figure 3) with resistance R, controllable silicon SCR, pin 1 is equipped with two contact springs 6 that are connected with row indication warning system, the two ends of circuits for triggering are connected with the contact spring 6 of pin 1 both sides respectively, and contact spring 6 after insert module respectively with the distributing frame warning system " " be connected with signal input part.
When switch and telephone set operate as normal; switch A, B line are communicated with (as shown in Figure 3) through fuse 4 with telephone set A ', B ' respectively; when producing over-current phenomenon avoidance, as long as wherein fuse 4 fusing, its light signal that sends triggers light-sensitive element 5; the resistance of light-sensitive element 5 is significantly reduced; impel the controllable silicon SCR conducting, trigger warning circuit 3, make the row indication send buzzing and report to the police; and make light-emitting diode 7 electrified light emittings, thereby can determine rapidly which protector breaks down.
Claims (3)
1, the fuse overcurrent protector used of distribution plant; constitute by pin (1), loam cake (8), lower cover (2), the fuse (4) that is connected with pin (1) and warning circuit (3); it is characterized in that: near fuse (4); storing has the light-sensitive element (5) of the light signal that sends when being enough to respond to fuse (4) fusing, and the signal that light-sensitive element (5) produces is as the triggering signal of warning circuit (3).
2, overcurrent protector according to claim 1 is characterized in that light-sensitive element (5) can be one, and is placed between two fuses (4).
3, overcurrent protector according to claim 2 is characterized in that pin (1) is equipped with two contact springs (6) that are connected with row indication warning system.
