The utility model is achieved through the following technical solutions: a kind of termination based on the earth leakage protective design; the output socket that comprises box body and be arranged on cartridge outer surface; also be provided with the power supply output loop that is connected with the output socket in described box body; use for the convenience of the user and to the protection of circuit; the utility model also comprises the attaching plug that is positioned at the corresponding output socket of cartridge outer surface; described attaching plug is connected with the power supply output loop, is in series with self-mending fuse F in described power supply output loop.
For better realizing the utility model, described power supply output loop is by power supply, and the power output end composition that is connected to both ends of power, and described power output end is connected with the output socket, and described power supply is connected with attaching plug.
Use for the convenience of the user, the utility model also are provided with switch and the neon bulb that is connected with the power supply output loop on the cartridge outer surface that is positioned at output socket one side, described switch is connected with self-mending fuse F, and described neon bulb is in parallel with self-mending fuse F.
For making the very little neon bulb normal operation of rated voltage, also be provided with the current-limiting resistance R in parallel with self-mending fuse F in described power supply output loop, described current-limiting resistance R connects with neon bulb.
Power output end socket described in the utility model be three-phase output end socket or two phase output terminal sockets all can, can select according to user's request.
When described power output end socket was the three-phase output end socket, described attaching plug was 3-phase plug or two-pin plug.
When described power output end socket was two phase output terminal sockets, described attaching plug was 3-phase plug or two-pin plug.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is simple in structure, and is with low cost, realize timely protection to circuit by the power supply output loop that is positioned at box body and is in series with self-mending fuse, and the safeties of the total control switch in circuit plays the double insurance effect.
(2) box body of the present utility model is provided with attaching plug and output socket; insert and extract all very convenient, in the circuit of building, use the utility model protective effect to be arranged to circuit especially in early days; more need not rewiring, installation and use are extremely convenient.
(3) the utility model is by in parallel with self-mending fuse resistance R and the neon bulb of mutually series connection, circuit break down cause that self-mending fuse is opened a way after, namely can make the neon bulb outside box body demonstrate index signal, so that the user in time overhauls.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment:
a kind of termination based on the earth leakage protective design, as shown in Figure 1, comprise box body 1, the attaching plug 3 that is arranged on the output socket 2 of box body 1 outer surface and is positioned at the corresponding output socket 2 of box body 1 outer surface, also be provided with the power supply output loop that is connected with attaching plug 3 with output socket 2 in described box body 1, for better realizing the utility model, described power supply output loop is by power supply, and the power output end that is connected to both ends of power forms, wherein power output end is connected with output socket 2, and power supply is connected with attaching plug 3, described power supply is 220V.
for realizing the protection to circuit, as Fig. 3, be in series with self-mending fuse F in described power supply output loop, in normal circuit, self-mending fuse F is low resistive state, the heat energy that the electric current of self-mending fuse F of flowing through on circuit produces is little, and when circuit is short-circuited or transship, self-mending fuse F is because the heat energy that electric current produces forms high-impedance state, its operating current is reduced rapidly, thereby circuit is limited and protects, after fault is got rid of, self-mending fuse F returns to low resistive state through supercooling, complete the protection to circuit, but in practice, use for more convenient user, the utility model also is provided with in the power supply output loop and self-mending fuse F tandem tap 4, with and the neon bulb 5 in parallel with self-mending fuse F.And described switch 4 and neon bulb 5 are located at respectively on box body 1 outer surface of output socket 2 one sides.
For making 5 normal operations of the very little neon bulb of rated voltage, also be provided with the current-limiting resistance R in parallel with self-mending fuse F in described power supply output loop, described current-limiting resistance R connects with neon bulb 5.The series connection diverter branch that forms due to current-limiting resistance R and neon bulb 5 is in operating state in parallel with conceited fuse F, thereby when circuit works, because the resistance value of diverter branch is very large, neon bulb 5 is starter not, only have when conceited fuse F forms high-impedance state, electric current is through current-limiting resistance R starter neon bulb 5, and neon bulb 5 sends ruddiness with the announcement of warning, thereby reminding user is in time changed and is fixed a breakdown, and has reached the purpose of fusing indication.
As shown in Figure 2, power output end socket 2 described in the utility model be set to three-phase output end socket or two phase output terminal sockets all can, facilitate the user to select; In like manner, described attaching plug 3 is set to 3-phase plug or two-pin plug also all can.The utility model is simple in structure, and is with low cost, can not only protective effect be arranged to circuit, more need not rewiring, and installation and use are extremely convenient.
The above; it is only preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, any simple modification, the equivalent variations on every foundation technical spirit of the present utility model, above embodiment done are within all falling into protection range of the present utility model.
