Abstract
A kind of driving power of bringing onto load defencive function; including a main casing; modular plug is equipped on rear side of the main casing; AC-DC converting circuit and control circuit are equipped in the main casing; low-voltage direct socket is equipped in front of the main casing, the modular plug is electrically connected with AC-DC converting circuit, and the AC-DC converting circuit is electrically connected with control circuit; the control circuit is electrically connected with low-voltage direct socket, and the main casing is equipped with LED display；The utility model has the beneficial effects that: having the loading functional of detection lamp string, user can be helped to select suitable lamp string load.
Description
Technical field
The utility model relates to a kind of driving powers, supply electricity to decorative chain power supply for alternating current to be converted to direct current.
Background technique
Decorative chain needs the power supply of direct current to supply power for, and generally uses in red-letter day or other celebratory events.Usually dress
Decorations lamp string can arrange in pairs or groups a driving power that the direct current that alternating current is converted into low pressure is electrically connected lamp string using, driving power.
Very greatly due to the external lamp string watt level variation on low-voltage direct socket, load is unstable, and user is often
It does not know about these to overlap carelessly, the normal use of lamp string is adversely affected.
Summary of the invention
In order to overcome the shortcomings of that existing driving power does not have load protection function, the utility model provides a kind of bringing onto load guarantor
The driving power of protective function.
The technical scheme in the invention for solving the technical problem is: a kind of driving power of bringing onto load defencive function, packet
A main casing is included, modular plug is equipped on rear side of the main casing, AC-DC converting circuit and control electricity are equipped in the main casing
Road, the main casing front are equipped with low-voltage direct socket, and the modular plug is electrically connected with AC-DC converting circuit, and the friendship is straight to be turned
It changes circuit to be electrically connected with control circuit, the control circuit is electrically connected with low-voltage direct socket, and the main casing is aobvious equipped with LED
Display screen；The control circuit is equipped with the load detecting module of a belt current load detecting, the LED display and control electricity
Road electrical connection；A light warning unit is additionally provided on the main casing, the light warning unit is electrically connected with control circuit.
Further, an alarming horn is additionally provided in the main casing, the alarming horn is electrically connected with control circuit.
The composed structure of control circuit as the prior art, is made of MCU and storage unit.
The utility model works as load excessive when lamp string is connected on low-voltage direct socket by user, on LED display
The load excessive printed words of meeting display scrolling, prompt consumer alert to reduce the length of connection lamp string.
Simultaneously when load is unstable lives appearance short circuit, light warning unit and alarming horn can issue acousto-optic letter
Number, prompt lamp string to use abnormal.
The utility model has the beneficial effects that: the 1, loading functional with detection lamp string, can help user to select
Suitable lamp string load.2, have the function of light and loudspeaker dual-alarm, in load abnormals such as lamp string short circuits, can warn
Show user.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic side view of the utility model.
Fig. 3 is the circuit diagram of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
In conjunction with attached drawing 1 to 3, a kind of driving power of bringing onto load defencive function, including a main casing 1, the main casing 1
Rear side is equipped with modular plug 2, and AC-DC converting circuit 3 and control circuit 4 are equipped in the main casing 1, is set in front of the main casing 1
There is low-voltage direct socket 5, the modular plug 2 is electrically connected with AC-DC converting circuit 3, the AC-DC converting circuit 3 and control electricity
Road 4 is electrically connected, and the control circuit 4 is electrically connected with low-voltage direct socket 5, and the main casing 1 is equipped with LED display 6；It is described
Control circuit 4 is equipped with the load detecting module 7 of a belt current load detecting, the LED display 6 and 4 electricity of control circuit
Connection；A light warning unit 8 is additionally provided on the main casing, the light warning unit 8 is electrically connected with control circuit 4.
Load detecting module 7 sends alarm signal when detecting that current loading is unstable or numerical value is more than maximin
Number give control circuit MCU.MCU retransmits information to LED display 6.
Further, an alarming horn 9 is additionally provided in the main casing, the alarming horn 9 is electrically connected with control circuit 4.
The composed structure of control circuit 4 as the prior art, is made of MCU and storage unit.
The utility model works as load excessive, LED display 6 when lamp string is connected on low-voltage direct socket 5 by user
The load excessive printed words of upper meeting display scrolling, prompt consumer alert to reduce the length of connection lamp string.
Simultaneously when load is unstable lives appearance short circuit, light warning unit 8 and alarming horn can issue acousto-optic
Signal prompts lamp string to use abnormal.
The utility model has the beneficial effects that: the 1, loading functional with detection lamp string, can help user to select
Suitable lamp string load.2, have the function of light and loudspeaker dual-alarm, in load abnormals such as lamp string short circuits, can warn
Show user.
