Abstract
The utility model provides an overcurrent protection socket, which is composed of elements of an outer shell (1), a contact inserting sheet (2), a bimetal release (3), a switch (4), a safety fuse (5), a resistance R, a capacitance C, a diode D, a luminous tube (6), etc. The utility model not only has the functions of overcurrent protection, overcurrent alarm and short-circuit protection, but also has the advantages of simple structure, low cost, and convenient use, safety and reliability.
Description
The utility model relates to a kind of overcurrent protection socket device, belongs to the household electrical outlet field.
At present, household electrical outlet of the prior art does not mostly possess overcurrent protection and overcurrent warning function, and is therefore still not ideal enough in use.
The purpose of this utility model provides a kind of over current protection retaining socket that has overcurrent protection and overcurrent warning function and have short-circuit protection function.
The purpose of this utility model is achieved in that it comprises shell (1), contact inserted sheet (2), bimetal release (3), switch (4), fuse (5), resistance R, capacitor C, diode D, luminous tube (6), with bimetal release (3), switch (4), fuse (5), resistance R series connection together and contact inserted sheet (2) with 1～10 and connect, in parallel after diode D and luminous tube (6) are cascaded with capacitor C and resistance R, switch (4), fuse (5) and luminous tube (6) are housed on the surface of shell (1).In use, when electric current surpassed the predetermined electric current value, the voltage drop that produces at the resistance R two ends at this moment will make the luminous warning of luminous tube (6), if at this moment also do not take measures, bimetal release (3) plays the effect of overcurrent protection because of overcurrent produces action power dump; Fuse (5) is made short-circuit protection and is used.
Owing to adopted above technical scheme; compared with prior art; the utlity model has overcurrent protection and overcurrent warning function and have short-circuit protection function, and simple in structure, cost of manufacture is cheap, esy to use, safe and reliable, therefore realized the purpose of this utility model.
Accompanying drawing 1 is an outside drawing of the present utility model;
Accompanying drawing 2 is an electrical schematic diagram of the present utility model.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing:
Resistance R in the present embodiment: the conducting voltage of 0.05 Ω, capacitor C: 1uF, luminous tube (6) is that the model of 2V, diode D is: 4007; With bimetal release (3), switch (4), fuse (5), resistance R series connection together and contact inserted sheet (2) with 3 and connect, it is in parallel after diode D and luminous tube (6) are cascaded with capacitor C and resistance R, switch (4), fuse (5) and luminous tube (6) are contained in the surface of shell (1), and all the other elements all are contained in the shell (1).
Claims (1)
1, a kind of over current protection retaining socket; it comprises shell (1), contact inserted sheet (2), bimetal release (3), switch (4), fuse (5), resistance R, capacitor C, diode D, luminous tube (6); it is characterized in that: bimetal release (3), switch (4), fuse (5), resistance R are connected together and are contacted inserted sheet (2) with 1～10 and connect; diode D and luminous tube (6) series connection back together is in parallel with capacitor C and resistance R, and switch (4), fuse (5) and luminous tube (6) are housed on the surface of shell (1).
