Specifically, the power input end comprises an L/N interface, the external equipment is connected with the power output end, the first switch module comprises a switch-SB 1, the second switch module comprises a switch-SB 2, and the time relay comprises a switch-KT 1. A specific model of time relay may be JSZ3A-C AC220V as shown.

Further, a first switch module is arranged in series with the power output end, and the first switch module comprises a self-locking switch; the second switch module is connected with the time relay module in series; the auxiliary contact of the time relay is connected with the power output end in series.

Specifically, in the external equipment branch, a switch-SB 1 is connected in series with the power output end (external equipment), and the switch-SB 1 is a self-locking switch; in the delay adjustment branch, a switch-SB 2 and a time relay-KT 1 are arranged in series; in the external device branch, an auxiliary contact-KT 1 of the time relay is arranged in series with the power supply output (external device) and in parallel with the switch-SB 1.

a. Manual disconnect control

As shown in fig. 1, when the self-locking switch-SB 1 of the external device branch is depressed, the external device is charged because-SB 1 is closed and the external device is turned on with L/N. When the self-locking switch-SB 1 of the external device branch is pressed again, the external device is not conducted with the L/N because-SB 1 is disconnected, and the external device is stopped to charge.

b. Timing off control

As shown in fig. 1, when the self-locking button-SB 1 is turned off, the reset switch-SB 2 is pressed to fully turn on the delay adjustment branch, and the time relay-KT 1 of the delay adjustment branch is triggered. The time relay can in principle be set arbitrarily, such as 0.5 hours, 1 hour, 3 hours, 6 hours, 9 hours. For example, the time relay may set the delay time to 6 hours.

After 6 hours, the auxiliary contact-KT 1 of the time relay of the external equipment branch is operated, the auxiliary contact KT1 of the time relay in the external equipment branch is disconnected, the external equipment is not conducted with the L/N (the self-locking button-SB 1 is disconnected at the moment), and the external equipment is stopped to be charged.

Further, the power input indication unit is used for indicating whether the power input end has power input. For example, the power indicator HL3 is on, indicating that the L/N has power input, otherwise, if the power indicator HL3 is off, indicating that the L/N has no power input.

By the embodiment, the external equipment can be charged by cutting off the data line manually, and also can be charged by cutting off the data line in a delayed or timed mode. The present embodiment discards the complex structure of the existing control circuit, and implements the power-off control function designed by the present invention by using a simple combination of electrical switches.

Example 2

As shown in fig. 2, the present embodiment provides a data line, including: power input end, power output end, automatic control unit and manual control unit

Specifically, the power input end comprises an L/N interface; in the external equipment branch, the power supply output end 3-4 is connected with external equipment; in the manual bypass, the first switch module comprises reset switches-SB 1-3/4; in the automatic branch, the second switch module comprises a reset switch-SB 2-1/2; in the delay adjustment branch, the time relay includes-KT 1-2/7. The specific model of the time relay can be JSZ3A-C AC220V.

Specifically, in the manual branch, the manual switch unit further includes a first auxiliary switch KA1; wherein, in the manual branch, the first switch modules-SB 1-3/4 and the coil KA1 of the first auxiliary switch are arranged in series; in the external device branch, the first auxiliary contacts KA1-5/9 of the first auxiliary switch are arranged in series with the power supply output 3/4 (external device).

Specifically, in the automatic branch, the automatic switching unit further includes a second auxiliary switch KA2; wherein, in the automatic branch, the second switch module-SB 2-1/2, the auxiliary contact-KT 1-1/4 of the time relay and the coil KA2 of the second auxiliary switch are arranged in series; in the external equipment branch, the first auxiliary contact KA2-5/9 of the second auxiliary switch is arranged in series with the power output end 3/4 (external equipment); in the delay adjustment branch, a second auxiliary contact-KA 2-7/11 of a second auxiliary switch is arranged in series with the time relay-KT 1-2/7. At this time, the first switch module includes the latching switches SB1-3/4. The second switch module includes a reset switch-SB 2-1/2. The first auxiliary contact KA2-5/9 of the second auxiliary switch is also arranged in parallel with the reset switch-SB 2-1/2.

Further, in the automatic branch, the third auxiliary contact KA1-4/12 of the first auxiliary switch is arranged in series with the second switch module-SB 2-1/2, the auxiliary contact-KT 1-1/4 of the time relay and the coil KA2 of the second auxiliary switch at the same time. In the manual bypass, the third auxiliary contact KA2-4/12 of the second auxiliary switch is arranged simultaneously in series with the first switch module SB1-3/4 and the coil KA1 of the first auxiliary switch.

a. Manual control

In the manual bypass, as shown in fig. 2, the self-locking switch-SB 1 is pressed to switch on the contacts 3, 4. Because the switch has a self-locking property, the manual branch is always conducted, KA2-4/12 is in a normally closed state, so that the KA1 coil is electrified, and the manual indicator lamp HL1 is lighted. The auxiliary contact KA1 of the external device branch is also turned on, and the contacts 5 and 9 are turned on, so that the external device is charged. And the auxiliary contacts KA1-4/12 of the automatic branch are changed from a normally closed state to a normally open state, and the automatic branch cannot be conducted at the moment.

When the self-locking switch SB1 is pressed again, the contacts 3 and 4 are opened. The KA1 coil in the manual bypass is not electrified, and the manual indicator lamp HL1 is turned off. The auxiliary contacts KA1-5/9 of the external equipment branch are disconnected, the power output of the power output end 3-4 is cut off, and the external equipment is stopped being charged. At this time, KA1-4/12 is changed from the normally open state to the normally closed state.

b. Automatic control

As shown in FIG. 2, when the reset switch-SB 2-1/2 button in the automatic branch is pressed, the auxiliary contact-KT 1-1/4 of the time relay and the third auxiliary contact KA1-4/12 of the first auxiliary switch are in a normally closed state, so that the KA2 coil in the branch is electrified, the auxiliary contact KA2-5/9 of the automatic indication branch is simultaneously closed, the continuous passage of the automatic branch is kept, the coil KA2 is continuously electrified, and the automatic indication lamp HL2 is lighted. At the same time, the auxiliary contacts KA2-5/9 of the external device branch are also closed and the external device is charged.

At the same time, the second auxiliary contact-KA 2-7/11 of the second auxiliary switch of the delay adjustment branch is closed, triggering the time relay-KT 1-2/7. Assuming that the time relay KT1 is timed for 6 hours, after 6 hours, the auxiliary contact-KT 1-1/4 of the time relay of the automatic branch will be automatically opened, thereby resulting in that the coil KA2 of the second auxiliary switch of the automatic branch is not electrified, the automatic indicator lamp HL2 is turned off, and simultaneously the first auxiliary contact KA2-5/9 of the second auxiliary switch of the external equipment branch is opened, and the external equipment is stopped from being charged.

According to the embodiment, the external equipment can be charged by cutting off the data line manually, and also can be charged by cutting off the data line in a time relay delay or timing mode. In this embodiment, the power-off control function designed by the present invention is realized by using a simple combination of the electric switches.

Example 3

As shown in FIG. 3, in the manual bypass, the first switch module includes a first reset switch-SB 1-3/4 and a third reset switch-SB 3-6/8. Wherein, -SB1-3/4 is a normally open reset switch, -SB3-6/8 is a normally closed reset switch. In the manual indicating branch, the first auxiliary contacts KA1-5/9 of the first relay are connected in parallel with-SB 1-3/4.

When the first reset switch-SB 1-3/4 button in the manual branch is pressed, the coil KA1 in the branch is electrified because the third reset switch-SB 3-6/8 and the third auxiliary contact KA1-4/12 of the first auxiliary switch are in a normally closed state, meanwhile, the auxiliary contact KA1-5/9 of the manual indication branch is closed, the continuous passage of the manual branch is kept, the coil KA1 is continuously electrified, and the manual indication lamp HL2 is lighted.

When the coil KA1 of the first auxiliary switch is energized, the first auxiliary contacts KA1-5/9 of the first auxiliary switch of the external equipment branch are triggered to be closed, and the external equipment is in a charging state. If the charging of the external equipment is needed to be stopped manually, the third reset switch-SB 3-6/8 can be triggered, when-SB 3 is triggered by the outside, the switch is switched from the normally closed state to the open state, at the moment, the manual branch circuit is opened, the coil KA1 of the first auxiliary switch of the manual branch circuit is not electrified, the first auxiliary contacts KA1-5/9 of the first auxiliary switch are correspondingly not contacted in the branch circuit of the external equipment, and the power supply output end stops charging the external equipment. The technical effect of stopping charging manually is achieved.

The automatic timing control part of this embodiment is identical to that of embodiment 2, and thus a step description of the operation thereof is omitted here.

By adopting any one of the three technical schemes, the function of manually or automatically powering off the data line can be realized, and the technical effects of safety and energy conservation can be generated while the convenience of use is brought to users.

As shown in fig. 4, the control operation box of the present invention has four indicator lamps, which sequentially represent-SB 1 (manual + indication), -SB2 (automatic + indication), -SB3 (stop) and HL3 (power indication). The on/off of the indicator light reflects whether the corresponding unit or module is in an operating state. Wherein the-SB 1 indicator light represents HL1 in embodiment 2 or 3, the-SB 2 indicator light represents HL2 in embodiment 2 or 3, and the-SB 3 indicator light represents HL4 (not shown, in parallel with-SB 3 in embodiment 3).

It should be understood that the foregoing examples of the present invention are provided merely for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention, and that various other changes and modifications may be made therein by one skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
