Abstract
The utility model discloses a flush mounted shock and over-current protector for panels, which is provided with a panel, a base, and terminals. The panel and the base are provided with light emitting diodes, an electric leakage switch, a fuse, and a resistor; one light emitting diode is connected with the resistor in series, and the light emitting diode and the resistor are connected with the two ends of the power input; another light emitting diode is connected with the fuse connect in parallel; the last light emitting diode is connected with the electric leakage switch in parallel; The flush mounted shock and over-current protector for panels has the functions of the electric shock protection, the over-current protection, and the indication, and the elements are arranged in a fluch mounted box in the centralization way. The utility model has the advantages of low cost, beautiful appearance, high theft-proof performance, reasonable design, and wide range of application.
Description
The utility model relates to the switching device that power distribution is used in the electricity field.
Now generally to the user for distribution mostly with single power-cutting switch; kilowatt-hour meter; fuse holder is installed on the interior base plate of a distribution box made of iron; some rural power distribution even dispersion are contained on the plank; so both dangerous not attractive in appearance yet; particularly there is not electric leakage; the indication of overcurrent and normal power supply; thereby to failure judgement; maintenance brings inconvenience; the Chinese patent 88211617 that the present technique field retrieves has been announced a kind of " concealed combined electric device spare "; its primary structure is a panel; functor and fixed mount are formed; the functor that is provided with has single connection plane switch; ganged switch; two hole socket; Three-hole socket; electric bell knob and indicator light; but above-mentioned concealed combined electric device spare does not have overcurrent; earth leakage protective and indication can only be as house services; pressing the line box uses.
The purpose of the utility model aim to provide a kind ofly have electric shock, overcurrent protection and deixis, electric device is installed concentratedly in a concealed installation box, cost is low, the panel concealed installation electric shock overcurrent protector of profile neat appearance.
Fig. 1 is the utility model contour structures front view;
Fig. 2 is the utility model contour structures vertical view;
Fig. 3 is the utility model circuit structure diagram.
Technical solution of the present utility model is: this panel flush mounted shock overcurrent protector has panel (1), base (2), binding post (3), upward and in the base (2) light emitting diode (D is installed at panel (1)1、D
2、D
3), the resistance (R that connects in leakage switch (LDB), fuse (RD) and the base1、R
2、R
3), light emitting diode D1With resistance R1Be connected power supply input two ends after the series connection, fuse (RD) is gone here and there in an input connecting line of power supply, light emitting diode (D2) and resistance R2After the series connection, be connected in parallel on fuse (RD) two ends, two cuttves of leakage switch (LDB) are serially connected in respectively between power supply two input lines and the output line, resistance R3Two ends connect respectively a cutter input and another cutter power output end of leakage switch (LDB), light emitting diode D3Be connected in parallel on cutter two ends of leakage switch (LDB).
Embodiment: as shown in Figure 1 and Figure 2; this panel concealed installation electric shock overcurrent protector has panel (1), base (2), binding post (3); panel (1) is connected into a concealed installation box with base (2); binding post (3) is fixed on the base (2), in panel (1) upper bed-plate (2) light-emitting diode (D is installed

Operation principle: during the normal power source power supply, current-limiting resistance R
1With light-emitting diode D
1After the series connection, be connected power supply input two ends, thereby during normal power supply, D
1There is electric current to flow through and luminous indication normal power supply.
Current-limiting resistance R
2With light-emitting diode D
2Be connected to fuse RD two ends after the series connection, during operate as normal, R
2, D
2By the RD short circuit, no current flows through, but when circuit, load overcurrent, fuse blows, input voltage directly is added in R
2, D
2, R
3Series loop, light-emitting diode D
2There is electric current to flow through, luminous this protector of indication overcurrent, fuse fuses, shields.
Circuit just often, light-emitting diode D
3By the short circuit of LDB leakage switch, D
3No current flows through, but when circuit load have the electric leakage and moved by leakage switch, voltage is added in R
3, D
3Two ends, D
3There is leaky in luminous indication loop.
Advantage: have electric shock, overcurrent protection and deixis, circuit spare is installed concentratedly in a concealed installation box, and cost is low, the profile neat appearance, theftproof performance is good, is a kind of New Product of reasonable in design, novel, wide application, is worth promoting.
