Abstract

The utility model discloses a universal safe socket of sensitive switch, which is composed of a cover, jack strips and an improved sensitive switch. The sensitive switch is arranged in the cover. The push rod of the sensitive switch extends out the surface of the cover with an appropriate height between the jack strips. The two ends of a flaky spring bridge connected with the push rod are fixedly connected with insulators. The insulator is provided with a moving contact. The moving contact and a power source are connected by a flexible conductor, and the lower parts of the two jack strips are provided with fixed contacts. The fixed contacts are fixed on the corresponding cover of the sensitive switch, and the recuperation of a spring acts on the push rod. The moving contact and the fixed contact are in normally open. When the push rod is pressed in a plug plane, the two poles of the plug are switched on. When the push rod is pulled out to an appropriate position, the two poles of the plug are switched off. The universal safe socket of sensitive switch can avoid accidents of electric shock resulted by that a metal object is misplaced in socket or people's hand reaches the electrode of a plug.

Description

Jogging switching universal safe socket

The utility model belongs to the improvement of safety socket.

In Tang Da on No. 85204638, the Chinese utility model patent of delivering in 1985 a kind of " safety socket " disclosed, this socket adds a partition on case inside, one end of partition is done a shifting block, and it is stretched out outside the case face, the central authorities of partition have this borehole jack of a hole to go on the middle step of case inner face, and can rotate around step, around medium pore, establish three holes, when stirring the shifting block of partition, partition just rotates, just the sealing of three holes on the case or open-minded can be prevented that thus accidental chance from causing the accident of human electric shock with time in the conductor patchhole.

This socket in use, need sealing or open-minded, cumbersome, when being switched on or switched off power supply, still can not overcome bigger electric arc and electromagnetic interference, on safety, can not avoid because of finger touches the life electric shock that plug electrode causes, and child inserts the electric shock accidents that causes in the jack of opening with conductor consciously.

The utility model proposes a kind of power on/off rapidly, the signal indication is clear and definite, electric arc is little, a little less than the electromagnetic interference, be strayed in the jack and finger has protection against electric shock safety socket reliable, easy to use when contacting plug electrode at metal object.

Briefly: the utility model be by case, jack strip and the sensitive switch that improved combine, sensitive switch is in case, jack strip is fixed on the sensitive switch housing, jack strip bottom device or as the fixed contact of sensitive switch, the two ends of the springs bridge in the sensitive switch affixed insulator, moving contact is set on the insulator, with flexible conductor moving contact is connected with power supply, power supply also can be set on insulator pass a bridge, play the effect in connection or deenergization and fixed contact electricity loop; Be connected a push rod in the middle of the springs bridge, the case surface is stretched out on push rod top, protrudes suitably height, overlapping the recovery spring in the push rod bottom, make push rod upwards, drive the spring bridge distortion that is connected and storage power makes two pairs of dynamic and static contacts be in normally open.During use, the push rod appropriate location is compressed on plug one plane, recovers the spring pressurized.Springs bridge energy stored obtains discharging and beats fast, and fixed contact energising plug electrode is also switched on; Pull the plug out of the socket to push rod depressed position not, recover spring and make push rod upwards and reset, the springs bridge is storage power again, and dynamic and static contact keeps normally open, and jack strip does not have.

Safety socket according to the utility model is made has following advantage: can avoid metal object to be strayed in the jack and finger touches on the plug electrode and the accident of human electric shock of taking place; Even child's left hand is pressed lower push-rod, the right hand is when take place getting an electric shock in the metal object patchhole, and the frightened inevitable push rod that unclamp left hand in the extremely short time makes jack strip outage, the unlikely serious accident that causes because of getting an electric shock; The socket energising time has tangible sound signal, therefore, only needs during not electricity consumption plug extracted and keeps plug still on socket to hearing the sound signal, and again the time spent, inside one pushes away i.e. energising, extremely easy to use; Socket when jack does not have the action of arclight contact, contacts, disconnects reliably when power on/off, and electric arc is little, a little less than the electromagnetic interference.

Accompanying drawing is the one group of socket schematic diagram that conforms with the utility model theme, 1 flexible conductor among the figure, and 2 sensitive switch housings, 3 fixed contacts, 4 moving contacts, 5 insulators, 6 springs bridges, 7 recover spring, and 8 push rods, 9 jack strips, 10 cases are the critical pieces that constitute this socket.Fig. 1 is the main cutaway view of reflection this socket internal structure, and Fig. 2 is a cutaway view on the parts such as springs bridge of reflection sensitive switch inside, and Fig. 3 is the left cutaway view of reflection sensitive switch transfer bar mechanism.

Referring now to accompanying drawing,, the utility model is set forth.In the accompanying drawings, sensitive switch housing (2) is arranged in the case (10), two jack strips (9) bottom is provided with fixed contact (3), be stuck in the groove on the sensitive switch housing with fixed form, on the inner core of the case between two jack strips, pass push rod (8), the suitable height of case is protruded in the push rod upper end, generally in 4 millimeter, the part of push rod in sensitive switch is connected the springs bridge (6) with lever amplification, its two ends affixed transparent insulator (5), fixing moving contact (4) on the insulator, moving contact is being communicated with power supply input pile crown with flexible conductor (1).Recovery spring (7) is overlapping the lower end of push rod, this spring one end seat is on the sensitive switch housing, one end heads on push rod, make push rod upwards, the springs bridging shape that is connected on the push rod and storage power, dynamic and static contact is in normally open, jack strip does not have electricity, and in plug electrode inserted jack, the plug plane was not pressed in push rod or insufficient pressure, the springs bridge still maintains the original state, push rod is pressed onto the appropriate location, and springs bridge energy stored obtains discharging and beats rapidly, makes dynamic and static contact reliably closed, jack strip obtains electricity, and plug electrode also has.At this moment, plug electrode is subjected to the effect of jack strip elastic clip power, overcomes the elastic force that recovers spring, makes push rod keep pressured state; The appropriate location that pulls the plug out of the socket, push rod is pressurized not, recovers spring the springs bridge is out of shape and storage power once more, and dynamic and static contact disconnects, and jack strip does not have.

So far, show the utility model jogging switching universal safe socket, can adapt to all kinds of residential houses, the occasions such as public building.
