Abstract

The utility model relates to a safety device for a power supply inserting connection component. An insulated cover cap of a jack socket is provided with a temperature sensor which is made of the thermal-sensitive material. The output terminal of the sensor is connected with a temperature display liquid crystal sheet and a temperature control speech IC through a comparison circuit, and the temperature display liquid crystal sheet and the temperature control speech IC are arranged on the socket; the upper surfaces of the temperature display liquid crystal sheet and the temperature control speech IC are coated with a layer of thermal-sensitive protective film. The temperature display liquid crystal sheet and the temperature control speech IC can be arranged between each two pairs of jacks. The insulator of a plug of the jack socket can be used as the temperature sensor made of the thermal-sensitive material, and the output end of the sensor is connected with the temperature control speech IC circuit through the comparison circuit. When the utility model is used, users can visually discover that the inserting connection component is overheated, and the utility model can send out the warning sound. Therefore, the overheated connection component can be processed in time so as to prevent a disaster from occurring.

Description

The safety device of power supply plug-in unit

The utility model relates to a kind of safety device of power supply plug-in unit, and refer in particular to the plug connector loose contact or overload and adstante febre, but the visual finding and the sound that gives a warning.

At present general family and office's pile have entered the electrification epoch, many in the required power supply, the socket of the former design interior circuit of building has not applied and has used, so that is plugged with the socket power extended line of several jacks in the former socket of being everlasting, and supplies the plug grafting power supply of several electrical equipment.Therefore, cause the excess load of circuit and socket and generate heat, user not hand touches and is difficult to find, and this way, not only takes electric power, and also is easy to lead to disaster.

Main purpose of the present utility model is to provide a kind of safety device of power supply plug-in unit, and the user is visual can to find that plug connector is overheated, and the sound that can give a warning, and is convenient to timely processing, prevents to lead to disaster.

The purpose of this utility model is achieved in that a kind of safety device of power supply plug-in unit, and the insulation cover cap of receptacle electrical connector is by the temperature sensor of hotness material; The output of transducer shows LCD panel and temperature control voice 1C by the comparison circuit jointing temp, and temperature shows that LCD panel and temperature control voice 1C are located on the socket, lining one deck hotness film protection on it.

Temperature shows that LCD panel and temperature control voice 1C are located between per two pairs of jacks.

The insulator of the plug of receptacle electrical connector can be the temperature sensor of hotness material, and the output of transducer connects temperature control voice 1C circuit by comparison circuit.

The insulation material of socket or lead that plug uses lining can be hotness film material temperature sensor.

The utility model is simple and reasonable, and is easy to use, safety, reliable.

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model socket schematic perspective view.

Fig. 2 is the utility model plug construction schematic perspective view.

Fig. 3 adopts temperature control voice IC temperature characteristics figure for the utility model.

Fig. 4 the utility model power unit circuit theory diagrams.

Fig. 5 is the utility model circuit part circuit theory diagrams.

As shown in Figure 1, the utility model plug connector many to spliced eye socket 1, insulation cover cap 2 is that the hotness material of primary raw material is made by the PC plastic cement, as temperature sensor, 3 of per two pairs of jacks or other appropriate locations, the output of transducer shows LCD panel and temperature control voice 1C4 by the comparison circuit jointing temp, and temperature shows that LCD panel and temperature control voice 1C4 are located on the socket, and lining one deck hotness film 5 is combined as a whole with insulation cover cap 2 on it.

The utility model in use, socket 1 is if there is between excess load or grafting copper sheet the bad and adstante febre of contact, the color of insulation cover cap 2 is that the rising of Yin Wendu changes, to dark red, the user is visual can be found by light red, produces the effect of early warning.When temperature rose above design temperature, voice 1C promptly went out the alarm song of the sound or poster automatically, in case produce disaster.

Shown in Figure 2; plug 6 insulators 7 of the utility model plug connector; be that the hotness material of primary raw material is made also by the PC plastic cement; equally as temperature sensor; in the appropriate location of this insulator 7, also be provided with a voice IC4, and one deck hotness film 5 protections that are covered thereon; when using,, will produce as above-mentioned same effect if generate heat.

Referring to Fig. 1,2 disconnected showing, socket 1 of the present utility model and coated electric wire that plug uses 8, the insulation material of its lining also is the hotness material, the electric wire heating is also by colourless thin out red and extremely dark red.

Shown in Figure 3, be the utility model temperature control voice IC temperature characterisitic.

Fig. 4 is the utility model power unit circuit theory diagrams figure, and Fig. 5 is the circuit pack circuit theory diagrams.Its action specification is as follows:

1, the plug connector temperature detector is used as in the U1 unit, can be along with variations in temperature produces Vcc voltage, Vcc delivers to comparator Vi and Vref makes comparisons (voltage quasi position of Vref can be adjusted), when n＜Vref, surpass design temperature, the Co of comparator does not send signal, when n＞Vref, surpass design temperature, the CO of comparator just sends signal, with U3 4KHZ squarer and generation caution sound.

2, U3 is a simple 4KHZ squarer.

3, U4 and door are to be used as the unit that U2 comparator and U3 squarer smear are used.
