Abstract
The utility model relates to a plug-type electric-wiring protective apparatus comprising phase line terminals and zero line terminals which are used for input and are configured to be plug-shaped, a tripping coil, a fault detection circuit and a tripper assembly. Current flows through the tripping coil under a normal operation mode. The fault detection circuit responds to a predetermined error condition of residual current of a phase line static contact and a zero line static contact, so that the tripping coil powers off. The tripper assembly responds to current change in the tripping coil and linearly moves relative to the tripping coil. A phase line moving contact and a zero line moving contact are respectively separated from the corresponding static contacts and can generate deformation under an effect of the tripper assembly, so that the phase line moving contact and the zero line moving contact are contacted with the corresponding static contacts. When the effect of the tripper assembly is removed, the phase line moving contact and the zero line moving contact recover a state of separating from the corresponding static contacts. The plug-type electric-wiring protective apparatus has a simple structure and can automatically cut off electric connection of electric appliances and power supply faults under a condition that fault current which is easy to lead to unsafe electricity use appears in the output phase line and/or zero line terminals, so that electricity use security is ensured.

In conjunction with Fig. 3 b; under "on" position not; phase line moving contact 5130; zero line moving contact 5120 respectively with corresponding fixed contact 5090; 5100 is spaced; when switching on and do not have residual current or residual current to surpass secure threshold; deformation can occur in phase line moving contact 5130 and zero line moving contact 5120 under the effect of release assembly 5170; thereby contact with corresponding fixed contact, (when not inserting corresponding socket (not charged) or residual current and surpassed the threshold value of safety requirements defined according to plug-type described in the utility model electricity Wiring protection device) phase line moving contact 5130 and zero line moving contact 5120 will return to corresponding fixed contact spaced under the effect of recuperability of self when the effect of release assembly 5170 removes.
Comprise as shown in Figure 1 two magnet ring CT1 and CT2 in the magnetic ring component 5110 shown in Fig. 3 b, it is configured to detect whether there is residual current in phase conductor 110 and zero line conductor 120.If there is enough large residual current, namely according to corresponding security regulations, this residual current has surpassed predetermined threshold value, signal processing circuit generates corresponding control signal according to the secondary induced current of magnetic ring component so, this control signal is correspondingly so that tripping coil 5036 is not charged, dropout iron core 5173 is under the effect of the recuperability of phase line moving contact 5130 and zero line moving contact 5120, to the direction motion away from tripping coil 5036.Thereby so that switching device 140 is positioned at the second place, and then being electrically connected between the input 5070 that disconnects phase conductor 110 and the output 5140, correspondingly, also will turn-off the input 5080 of zero line conductor 120 and the electrical connection between the output 5150.
Fig. 4 a shows the trip status view according to plug-type electricity Wiring protection device of the present utility model, and Fig. 4 b shows the reset mode view according to plug-type electricity Wiring protection device of the present utility model.
Shown in Fig. 4 b, when tripping coil 5036 energising, form magnetic field.Dropout iron core 5173 is inhaled in the tripping coil 5036, and be adjacent to described static iron core 5040, moving contact push rod 5172,5171 on the release assembly 5170 drives respectively phase line moving contact 5130 and zero line moving contact 5120 produces deformation, to contact with corresponding fixed contact.Particularly, static iron core one end 5041 is in the riveted holes 5052 that is riveted in the magnetic conduction frame 5050.Because dropout iron core 5173 and release assembly 5170 link together, so the displacement of dropout iron core 5173 will cause release assembly 5170 to the direction motion of tripping coil 5036, simultaneously, moving contact push rod 5172 and 5171 on the release assembly 5170 acts on respectively on the zero line moving contact shell fragment 5122 of the phase line moving contact shell fragment 5132 of phase line moving contact 5130 and zero line moving contact 5120, so moving contact links with the release assembly, so, static contact 5091 on the moving electrical contact 5131 of phase line moving contact 5130 and the moving electrical contact 5121 of zero line moving contact 5120 and the phase line fixed contact 5090 and the static contact 5101 on the zero line fixed contact 5100 contact, simultaneously, one end 5092 of phase line fixed contact 5090 and zero line fixed contact 5100,5102 all is to pass magnetic ring component 5110 to be welded on the printed substrate 5010 with output phase terminal 5140 and output zero terminal 5150 respectively, so, when two pairs of contacts contact, just finished the electrical connection of input with output.
Shown in Fig. 4 a, when not having electric current to flow through in described tripping coil 5036, magnetic field disappears.Because when reset mode; phase line moving contact 5130 and zero line moving contact 5120 are by 5170 pullings of release assembly and keep certain distortion; this moment, this confining force was owing to the disappearance in magnetic field has not existed; thereby phase line moving contact 5130 and zero line moving contact 5120 are because the recuperability of himself can turn back to the home position; so release assembly 5170 and dropout iron core 5173 are under the effect of the recuperability of phase line moving contact 5130 and zero line moving contact 5120; to the direction motion away from tripping coil 5036; moving electrical contact 5131 on this moment phase line moving contact 5130 and the zero line moving contact 5120; 5121 and phase line fixed contact 5090 and zero line fixed contact 5100 on static contact 5091; 5101 disconnect; realize the disjunction of input with output, effectively protected the safety of electrical appliance and the person.
Whether according to an embodiment of the present utility model, plug-type electricity Wiring protection device also comprises working station indicator LED (referring to Fig. 1), and itself and tripping coil 5036 are connected in parallel, to have electric current to flow through in the indication tripping coil.And plug-type electricity Wiring protection device has opaque shell; and be provided with the transparent plastic article that extends inwardly to described working station indicator at described shell so that the light of described working station indicator from described plug-type electricity Wiring protection device outside as seen.Thus so that the position of working station indicator can change flexibly, to adapt to the circuit structure of enclosure.
