Abstract
The utility model relates to a soft start socket preventing electric sparks. The soft start socket comprises a housing, jacks, conducting seat sheets, a soft start voltage control circuit and a trigger switch. The soft start voltage control circuit is connected on a main line of a socket power circuit and is controlled by the trigger switch. The trigger switch is disposed under the seat sheets in the jacks. When a household appliance plug is inserted into the jacks, plug copper sheets firstly contact with the conducting seat sheets, and the circuit is not switched on at the time. When the plug copper sheets are continuously inserted into a lower part of the jacks, the plug copper sheets would trigger the trigger switch, and then the whole circuit is switched on. The soft start voltage control circuit makes voltage between two ends of a household appliance slowly increase to 220V. Since voltage jumping does not exist in processes of inserting and pulling out the plug, soft start socket would not generate the electric sparks.
Description
Technical field
The utility model relates to a kind of soft start socket that prevents electric spark, belongs to household appliance.
Background technology
Along with increasing of household electrical appliance quantity, degree of dependence to socket is also increasing, but a unavoidable potential safety hazard is arranged always when using socket, namely disconnect at that moment at plug contact base conductive seat sheet or plug and socket conductive seat sheet, can produce electric spark, and this phenomenon is just as a time bomb that is imbedded in ours at one's side, light then our electrical equipment, socket are burnt out.Heavy then initiation fire causes our lives and properties to have a strong impact on.At home and abroad the neither one effective method solves this problem so far, and therefore addressing this problem becomes an extremely urgent thing.
Summary of the invention
The purpose of this utility model is: a kind of soft start socket that prevents electric spark is provided.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of soft start socket that prevents electric spark comprises shell, jack, conductive seat sheet, trigger switch and soft start voltage control circuit; It is characterized in that: the soft start voltage control circuit is connected on the main line of socket power circuit, whole socket power circuit is controlled by a trigger switch, trigger switch is arranged on the conductive seat sheet below in the jack, when inserting plug, the plug copper sheet contacts first the conductive seat sheet, and this moment, circuit was not also connected, when the plug copper sheet continues toward the insertion of jack below, can trigger trigger switch, this moment, whole circuit was connected, and the soft start voltage control circuit can make the voltage at household electrical appliance two ends slowly be increased to 220V; When pulling up plug, trigger switch can disconnect first, and the voltage at household electrical appliance two ends can slowly fall from 220V little of 0V, owing to the process of inserting and pull the plug out of the socket does not all have the jumping phenomenon of voltage, so can not produce electric spark.
The utlity model has following beneficial effect: (1) can prevent effectively that plug from producing electric spark when inserting and extracting jack, increased the security reliability of electricity consumption in the family life; (2) with low cost, be convenient to promote.

Embodiment
A kind of soft start socket that prevents electric spark comprises shell 1, jack 2, conductive seat sheet 4, trigger switch 5 and soft start voltage control circuit; The soft start voltage control circuit is comprised of inductance element 12, household electrical appliance 13 and capacity cell 14; Trigger switch 5 is comprised of spring 6, switch shrapnel 7, switch contact 8 and slide block 9.It is characterized in that: whole socket power circuit is by 5 controls of a trigger switch, the soft start voltage control circuit is connected on the main line of socket power circuit, trigger switch 5 is arranged on conductive seat sheet 4 belows in the jack 2, when inserting home electric appliance plug, the plug copper sheet contacts first conductive seat sheet 4, this moment, circuit was not also connected, when the plug copper sheet continues toward the insertion of jack below, can trigger trigger switch 5, this moment, whole circuit was connected, and the soft start voltage control circuit can make the voltage at household electrical appliance 13 two ends slowly be increased to 220V; When pulling up plug, trigger switch 5 can disconnect first, and the voltage at household electrical appliance 13 two ends can slowly fall from 220V little of 0V.Because the process of inserting and pulling the plug out of the socket does not all have the jumping phenomenon of voltage, so can not produce electric spark.
As shown in Figure 3, the soft start voltage control circuit is realized slowly increasing and the method that reduces voltage is: the soft start voltage control circuit is by inductance element 12, household electrical appliance 13 and capacity cell 14 form, when trigger switch 5 closures, when circuit is connected, inductance element 12 can stop electric current moment change large, the voltage at household electrical appliance 13 two ends can slowly be increased to 220V, after circuit is stable, the voltage at capacity cell 14 two ends equals the voltage at household electrical appliance 13 two ends, when trigger switch 5 disconnects, because capacity cell 14 has a discharge process in the soft start voltage control circuit, make the voltage at household electrical appliance 13 two ends can slowly reduce to 0V.
As shown in Figure 4, trigger switch 5 by the method that the plug copper sheet of household electrical appliance 13 triggers is: trigger switch 5 is comprised of spring 6, switch shrapnel 7, switch contact 8 and slide block 9, and when switch shrapnel 7 contacted with switch contact 8, circuit was namely connected.When inserting plug, the plug copper sheet contacts first conductive seat sheet 4, because switch shrapnel 7 does not also contact with switch contact 8, this moment, circuit was not also connected, when the plug copper sheet continues down to be inserted into contact slipper 9 top-right curved edge 10, slide block 9 can be moved to the left and make spring 6 compressions, drive switch contact 8 to the direction motion of switch shrapnel 7 and both are contacted, this moment, whole circuit was connected, when pulling up plug, the plug copper sheet can leave first the curved edge 10 on the slide block 9, and this moment, compressed spring 6 can make slide block 9 move right, and caused switch shrapnel 7 to separate with switch contact 8.
Among Fig. 2, identical with trigger switch 5 a, trigger switch of place in circuit not is set on the right, its objective is in order to allow the stressed symmetry of copper sheet of plug.
This socket is compared with traditional socket, can effectively stop can reduce household electricity security incident odds because insert or extract the phenomenon of receptacle sockets moment generation electric spark at home electric appliance plug, has larger practicality and certain market prospects.
