Embodiment
In order to understand structure of the present utility model, function and effect better, the following preferred embodiment of existing utilization is also described in detail by reference to the accompanying drawings.Should be understood that, the embodiment that the structural design of example and following description the utility model combine is not intended to limit according to all embodiments of the present utility model.
First see Figure 1A-1B, Fig. 3 A-3B and composition graphs 5; can comprise according to the plug with flameproof protection device of the present utility model the insulation shell be made up of upper shell 1 and lower house 2, control circuit board 7 to be positioned in this insulation shell and to be electrically connected with corresponding controlling organization.Reset button 6 protrudes from upper shell 1 outside and connects reset switch 10 (Fig. 5) to form reset switch assembly RESET.The input inserted sheet that figure disengages comprises zero line input inserted sheet 3, live wire input inserted sheet 4, and selectively comprises ground wire inserted sheet 5.In the execution mode shown in Figure 1A-1B, the temperature detect switch (TDS) 9 being electrically connected to control circuit board 7 is arranged between zero line input inserted sheet 3 and live wire input inserted sheet 4, inputs the temperature of inserted sheet and passed in trip circuit by temperature signal with Real-Time Monitoring.Although show a temperature detect switch (TDS) between input inserted sheet in this embodiment, but what those skilled in the art will be understood that is, depend on actual needs, it is all possible that one or more sides of input inserted sheet arrange one or more temperature detect switch (TDS).In order to monitor the temperature of input inserted sheet rapidly and accurately, can preferably temperature detect switch (TDS) 9 and zero line input inserted sheet 3 and live wire input to arrange respectively between inserted sheet 4 be made up of Heat Conduction Material lead warm sheet 8.But, also can consider temperature detect switch (TDS) 9 to be directly set to contiguous input inserted sheet.Such as, as shown in figs 3 a and 3b, two temperature detect switch (TDS)s 9 are provided, thus eliminate the needs of leading warm sheet.
Fig. 2 A-2B and Fig. 4 A-4B shows according to the socket with flameproof protection device of the present utility model.This socket forms insulation shell by upper shell 1 and lower house 2 equally, and arranges the control circuit board 7 be electrically connected with corresponding controlling organization wherein.Export contact chip and comprise zero line output contact chip 30, live wire output contact chip 40, and selectively comprise ground contact sheet 50.With the structural similarity of above-mentioned plug, export contact chip 30 and live wire at zero line to export between contact chip 40 and be provided with temperature detect switch (TDS) 9, and can according to actual needs at temperature detect switch (TDS) 9 and export provide to lead warm sheet 8 (Fig. 2 A-2B) or do not provide between contact chip and lead warm sheet (Fig. 4 A-4B).
In use, the plug that there is flameproof protection device according to of the present utility model or the principle of socket identical, below for have lead warm sheet socket composition graphs 5 to describe Temperature-control Monitoring process in detail.
Under normal service condition, the temperature that zero line exports contact chip 3, live wire exports contact chip 4 of socket is in safe temperature range, the temperature leading warm sheet 8 is less than or equal to the temperature that zero line exports contact chip 3, live wire exports contact chip 4, therefore the temperature of temperature detect switch (TDS) 9 is less than predetermined temperature value, temperature detect switch (TDS) 9 can not start short-circuited coil SOL, and coil SOL does not have electrical socket can continue to use.Otherwise, when the zero line of socket exports temperature that contact chip 3 and/or live wire export contact chip 4 higher than safe temperature range, the temperature leading warm sheet 8 also can increase, and then temperature detect switch (TDS) 9 can detect the temperature exporting contact chip and is greater than predetermined temperature value, temperature detect switch (TDS) 9 starts, short-circuited coil SOL obtains electric, and cuts off reset switch 10, thus is disconnected circuit, make user can not continue to use socket, only have after failture evacuation, again depress reset button 6, could continue to use.
Technology contents of the present utility model and technical characterstic have disclosed as above; but those skilled in the art should be able to will be appreciated that; under creative ideas of the present utility model; the changes and improvements of various structural or logicality can be carried out above-described embodiment, but all belong to protection range of the present utility model.Specific embodiment described above is not intended to limit according to all embodiments of the present utility model.Protection range of the present utility model determined by claim.
