Abstract

The utility model discloses a power safety socket, which comprises a casing 1 with a jack, a connection post 10 and a seat base plate 19. The seat base plate 19 is provided with a pair of mounting blocks 5 and 5.1, conductive pieces 3 and 3.1 which are arranged at the upper parts of the mounting blocks 5 and 5.1 through rotary shafts 6 and 6.1; rotary blocks 4 and 4.1 are positioned at the lower parts of the mounting blocks 5 and 5.1 through rotary shafts 7 and 7.1; and the middles of the rotary blocks 4 and 4.1 are respectively provided with elastic pressure conductive rods 8 and 8.1; moreover, the rotary blocks 4 and 4.1 are respectively provided with replacement springs 17 and 17.1 at the middle of the rotary shafts 7 and 7.1; and the free ends of the rotary blocks 4 and 4.1 and conductive pieces 3 and 3.1 are provided with pull wires 9 and 9.1. By the structure, the utility model promises safer usage of the power socket and closer contact between the plug 20 and the socket; besides, regardless of the width, the plug will not loose, thereby being more reliable in using.

Description

The power safety socket

The utility model relates to a kind of power safety socket.

Supply socket is indispensable a kind of extremely ordinary appliances element in the modern life, if use is improper a little, just can cause serious together security incident.Convenience problem around solving its fail safe and use in recent years, various kinds of power safety sockets also occurred.As: on 09 20th, 2000 disclosed, publication numbers is that 2397624 Chinese utility application discloses the extremely strong safety power source plug socket of a kind of fail safe.It is to be provided with on slideway the slide block that moves at corresponding socket, promotes flexure strip and stator joins through slide block, power supply is delivered on the metal connecting sheet of another socket correspondence, and is shown by status display circuit, automatic switch, easy to use, advantage such as the life-span is long.Also having on November 10th, 1999 disclosed, publication number is that 2348501 Chinese utility application disclose a kind of safety power source plug socket, its structure is: be fixed with a shell fragment on the spring leaf of socket, switch insulation on shell fragment and the power line is connected and fixed, and switch and shell fragment interlock.Spring leaf on the socket is not charged at ordinary times, and only after the inserted sheet insertion of plug put in place, power supply was just understood conducting, like this with regard to the thorough Electrical Safety problem that has solved socket.However, promote slide block or inserted sheet and insert and put in place if innocent child is inserted a socket with copper sheet or iron nail, still can cause the generation of electric shock accidents, it is too of a specified duration to also have supply socket to use, and very easily causes the loosening phenomenon of plug and socket generation.

The purpose of this utility model is to be to overcome on the basis of above-mentioned shortcoming, a kind of novel structure is provided, uses safer, more reliable power safety socket.

For achieving the above object, power safety socket of the present utility model, the shell, binding post, the seat base plate that comprise carrying spigots, wherein there are paired mounting blocks, corresponding shell socket back that conducting strip is arranged on the seat base plate, conducting strip is installed in the top of mounting blocks by rotation axis, and conducting strip can move downward along rotation axis; Moving block is installed in the lower curtate of mounting blocks by rotation axis, and moving block can move upward along rotation axis, and the centre position of moving block has one to suppress conducting rod respectively; Moving block is equipped with back-moving spring respectively in the centre of rotation axis; The free end of moving block and the free end of conducting strip have backguy.

As a kind of improvement of the present utility model, described conducting strip can be made the conducting strip of " U " shape described in the power safety socket.

As another kind of improvement the of the present utility model, the centre position of moving block described in the power safety socket can be installed the elastic conducting strip of " U " shape respectively.

After adopting this structure, when socket does not plug in, because suppressing conducting rod directly links to each other with power-line terminal by lead, suppressing conducting rod is installed on the moving block, moving block is under the effect of back-moving spring, be not communicated with conducting strip below the socket, the conducting strip below the socket is not charged, if the conducting strip that touches below the socket with hand is safe; If child inserts in the jack with copper sheet or iron nail because of carelessness, copper sheet or iron nail act on the conducting strip, and the moving block that backguy only spurs in the another one hole rotates, and conducting strip is still non-conductive in this jack, and also be safe this moment.When socket plugged in, conducting strip moved downward under the effect of plug, affected moving block to move upward by backguy, made to suppress that conducting strip contacts energized in conducting rod and the jack.In addition, because the reaction force of action of reset spring on moving block can make plug tightr with contacting of socket.It is loosening to also have the width of plug can not produce, and uses more reliable.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the front view of a kind of tip jack in the utility model;

Fig. 2 is the schematic diagram that a kind of tip jack shown in Figure 1 is taken away shell;
