Property contact.
Control-rod 20 is rotatably mounted in jack body 10, for example, can pass through a peace as shown in Figure 1A to Fig. 1 D
The installation axle 115 of seat 114 and one is filled to be arranged on the upper surface of the insulation shell 11.Inserted corresponding to slotting pawl insertion in plug 40
During hole 111,112,113, one end of control-rod 20 can insert the CONTACT WITH FRICTION of pawl 41 with one, and in the drive lower edge of the slotting pawl 41
First direction is rotated, and the other end of control-rod 20 described in rotary course applies one to the first contact 31 of normally opened contact 30 to be made
Pressure of first contact 31 towards second contact 32 so that the first contact 31 is in the presence of the pressure with second
Contact 32 is in contact；When the slotting pawl of plug 40 removes jack 111,112,113, the first contact 31 can be used as control-rod
20 reseting shrapnel, control-rod 20 is set to be rotated along direction opposite to the first direction, the first contact 31 and the second contact 32
Disconnect contact.
From Figure 1A to Fig. 1 as can be seen that with one end CONTACT WITH FRICTION with control-rod 20 in the utility model embodiment in D
It is that zero line inserts the description that carries out in case of pawl 41 to insert pawl, in practical application, with inserting for one end CONTACT WITH FRICTION of control-rod 20
Pawl can also be any one other slotting pawl or the combination of two or three slotting pawls.
In the utility model embodiment, one end that control-rod 20 is in contact with the slotting pawl 41 of zero line is cambered surface.So, not only exist
Corresponding to the slotting pawl insertion of plug 40 during jack 111,112,113, control-rod 20 can insert the CONTACT WITH FRICTION of pawl 41 with zero line, even if
When the slotting pawl of plug 40 removes jack 111,112,113, control-rod 20 can also insert the CONTACT WITH FRICTION of pawl 41 with zero line, this
The drive lower edge direction opposite to the first direction that sample control-rod 20 can also insert pawl 41 in zero line rotates, so as to accelerate
The reset of control-rod 20.
In the utility model embodiment, the control-rod 20 is Z-shaped, and the axis of rotation of the control-rod 20 is positioned at described
At Z-shaped top turning point, this make it that control-rod can also be in the work of self gravitation when the slotting pawl of plug removes the jack
Complete to reset with lower, so as to further speed up the reset of control-rod.
The body of smart jack in the utility model embodiment also includes：Central control unit 15 and controlling switch unit
16, in one embodiment, central control unit 15 for example can be microcontroller chip (MCU), controlling switch unit example
It such as can be relay.
Wherein, the switch contact of controlling switch unit 16 is connected in live wire loop, the control terminal of controlling switch unit 16
It is connected between central control unit 15 and live wire contactor 12.
Normally opened contact 30 in the utility model embodiment is connected to central control unit 15 and controlling switch unit 16
Between control terminal.
In the utility model embodiment, central control unit 15 can be located at a printed circuit board (PCB) with controlling switch unit 16
On (pcb board) 17, correspondingly, normally opened contact 30 can be fixedly welded on the pcb board 17.In addition, the utility model embodiment
In jack body 10 also include a pcb board 18.
Fig. 2A to Fig. 2 C is the circuit diagram of the anti-electric shock socket in the utility model embodiment.Fig. 2A is the slotting pawl of plug 40
When being not inserted into jack 111,112,113, normally opened contact 30 disconnects and the switch contact of controlling switch unit 15 is also under disconnection
Circuit diagram；When Fig. 2 B are that the slotting pawl 41,42,43 (live wire inserts pawl) of plug 40 inserts jack, normally opened contact 30 is closed but controlled
Circuit diagram under the switch contact disconnection of switch element 15；Fig. 2 C are that normally opened contact 30 closes and controlling switch unit 15
The switch contact also circuit diagram under closure situation.
It is can be seen that with reference to Fig. 2A to Fig. 2 C in the case where normally opened contact 30 disconnects, controlling switch unit 16 can not connect
The control from central control unit 15 is received, therefore live wire loop is off all the time.Only exist in normally opened contact 30
In the case of being closed when plug 40 inserts jack under the control of control-rod 20, controlling switch unit 16, which can just receive, to be come from
The control of control unit 15 is entreated, realizes the switch control of smart jack.
In addition, in the case of jack body 10 is other types of jack body, the normally opened contact 30 is attached to fire
Between linear contact lay device 12 and live wire.
From such scheme as can be seen that because the anti-electric shock socket in the utility model embodiment is normally opened tactile with one
Point, and the normally opened contact after inserting pawl and a control-rod CONTACT WITH FRICTION, drives the control only after plug insertion socket
A contact of the other end of bar into the normally opened contact applies the pressure for making the normally opened contact closure；Socket is left in plug
When, the normally opened contact is alternatively arranged as the back-moving spring of the control-rod while contact is disconnected.It can be seen that the application's is anti-
Electric shock socket can not only improve the security of socket, and simple in construction.
In addition, by the way that control-rod is arranged into cambered surface with one end that the slotting pawl of plug is in contact, not only can inserting in plug
Corresponding to pawl insertion during jack, control-rod can insert pawl CONTACT WITH FRICTION with zero line, and remove the jack in the slotting pawl of plug
When, control-rod also also can insert the drive lower edge of pawl and the first direction with slotting pawl CONTACT WITH FRICTION, such control-rod
Opposite direction rotates, so as to accelerate the reset of control-rod.
In addition, the anti-electric shock socket in the utility model embodiment both can be the socket of tradition machinery control, can also
It is the smart jack of central control unit control.
Further, by the way that control-rod is arranged into Z-shaped, and the axis of rotation of the control-rod Z-shaped is leaned on positioned at described
On turning point at so that plug slotting pawl remove the jack when, control-rod can also be complete in the presence of self gravitation
Into reset, so as to further speed up the reset of control-rod.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
