Abstract
The utility model relates to a temperature control protector for a power supply socket. The utility model is characterized in that the inner part of the power supply socket is provided with a temperature conducting electrode connecting sheet (5), wherein, one side of which is fixed with a cover plate (4). An insulation layer (7) is coated on the cover plate, and a window is arranged on the insulation layer. A cover plate contact (1) is fixed on the cover plate which is arranged in the window. A bimetal sheet stationary contact (8) is arranged in the temperature conducting electrode connecting sheet (5). A bimetal sheet (3) which is extended to the cover plate contact (1) is fixed on the stationary contact (8), and the endpoint of the bimetal sheet (3) is fixed with a movable contact (2). The utility model can cause the electric current to be cut off when the power supply socket is heated to T DEG C because of poor contact, etc. When the temperature falls down to the normal value, the electric current can be switched on automatically. The protector is composed of the original parts of the power supply socket, the congested assembly in the power supply socket can not be generated, and the assembly and the maintenance are convenient.
Description
The utility model relates to supply socket, particularly the temperature control protective device of socket.
At present, the safety utilization of electric power of supply socket more and more causes people's attention, durable and indeformable except the jack copper sheet of socket, keep outside the excellent contact, other indicator light, fuse unit also occurs in supply socket successively, the temperature-sensitive control electric installation that particularly has a bimetal leaf is introduced the record in the supply socket, obtained more safety guarantee when making supply socket in working order but the present temperature-sensitive control electric installation that has bimetal leaf is a self-contained unit, be fixed in the space of supply socket, install to this by the air transmitted heat in the supply socket, clearly, this method of transmitting heat is not only slow, and the temperature that passes to this device can not truly reflect wire overloading, or electrical equipment meets accident and generates heat and be transmitted to the temperature of socket copper sheet by electric wire.
The purpose of this utility model provides a kind of supply socket temperature control protective device; can be in the loose contact of supply socket, electric wire overload, electrical equipment meets accident and cause heating; make when the electrode copper sheet surpasses the temperature that allows in the supply socket electrode copper sheet directly fast, evenly lead temperature and cut off electric current; automatic making current when temperature drops to normal value; and utilize the former parts of supply socket to constitute protective device jointly; do not cause and squeeze dress in the supply socket, be convenient to assembling and maintenance.
Technical solution of the present utility model is to lead warm electrode connecting piece in supply socket, the one side is fixed with cover plate, clad type is fixed with insulating barrier on the cover plate, window is arranged on insulating barrier, be fixed with the cover plate contact on the cover plate in the window, leading has the bimetal leaf fixed contact on the warm electrode connecting piece, be fixed with the bimetal leaf that stretches to the cover plate contact on the fixed contact, and its end points is fixed with moving contact.
The above leads warm electrode connecting piece stage casing is a uncovered box, and two ends are outwardly directed brace, and its bimetal leaf is hidden in the uncovered box, and cover closure is in the box mouth.
Window on the insulating barrier of the present utility model is positioned at cover plate leads on the one side of warm electrode connecting piece relatively.
More than cover plate of the present utility model cover plate lead-in wire is arranged.
Operation principle of the present utility model is; the electric current that is imported by cover plate lead-in wire enters socket and leads warm electrode connecting piece behind cover plate and bimetal leaf; when supply socket causes adstante febre because of loose contact; or electric wire transships, electrical equipment meets accident and causes adstante febre; when socket electrode slice temperature is elevated to set point T ℃; the bimetal leaf perk and with the cover plate contact separation, circuit disconnects, and plays the safety utilization of electric power protective effect.After pulling out plug or powered-down switch, socket electrode copper sheet temperature descends, and when dropping to normal value, bimetal leaf resiles and links to each other with the cover plate contact.
The utility model has the advantages that can be because of loose contact; the electric wire overload; electrical equipment meets accident and when causing the heating of electrode copper sheet in the supply socket to surpass the temperature that allows; the electrode copper sheet directly fast, evenly lead temperature and cut off electric current; electric current is connected automatically when temperature drops to normal value; and utilize the former parts of supply socket to constitute protective device jointly, and do not cause and squeeze dress in the supply socket, be convenient to assembling and maintenance.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 organigram of the present utility model;
Fig. 2 left apparent structure schematic diagram of the present utility model.
Shown in Fig. 1,2, the utility model is to lead warm electrode connecting piece 5 in supply socket, the one side is fixed with cover plate 4, clad type is fixed with insulating barrier 7 on the cover plate 4, on insulating barrier 7 window is arranged, be fixed with cover plate contact 1 on the cover plate 4 in the window, leading on the warm electrode connecting piece 5 has bimetal leaf fixed contact 8, be fixed with the bimetal leaf 3 that stretches to cover plate contact 1 on the fixed contact 8, its end points is fixed with moving contact 2.Leading warm electrode connecting piece 5 stage casings is a uncovered box, and two ends are outwardly directed brace, and its bimetal leaf 3 is hidden in the uncovered box, and cover plate 4 is closed in the box mouth.Window on the insulating barrier 7 that coats on the cover plate is positioned at cover plate 4 leads on the one side of warm electrode connecting piece 5 relatively.Cover plate 4 has cover plate lead-in wire 6.
Claims (4)
