Description
Technical field
The utility model belongs to electrical equipment control field more particularly to a kind of integral type charging gun with overheat protector.
Background technology
In existing charging gun, in order to more reliablely and stablely work, corresponding monitoring and protecting is generally all introduced
Module, such as over under-voltage protection circuit, effect are that triggering is corresponding when operating voltage is higher or lower than corresponding reference voltage
Action, can circuit parameter be adjusted to normal level in time.But in existing charging gun unpromising circuit key
Element, such as the function of temperature detection on relay band.Because of prolonged work, the contact of relay can accumulate largely charging gun
Heat and cause relay operating temperature to rise, in national standard the operating temperature of regulation charging gun between -30~50 DEG C,
70 DEG C may be raised to plus temperature liter when generating heat serious, working condition is made to be affected.For this problem, current solution skill
Art is to increase cooling fin or radiator in circuit to reduce the temperature of circuit board, or appropriate increase board area and modification are walked
Crucial in the circuit and serious component of fever is placed on best heat dissipation position by line rule.
Utility model content
Technical problem to be solved in the utility model is：It is proposed a kind of integral type charging gun with overheat protector, it can be certainly
Dynamic detection relay temperature, charge circuit is disconnected in the case where temperature is excessively high, can effectively solve background technology described problem and
Circuit structure is simpler, and cost is relatively low and reliability is higher.
A kind of integral type charging gun with overheat protector of the utility model adopts the following technical scheme that：A kind of band overheat protector
Integral type charging gun, including gun body, pipette tips, input cable, output cord, the pipette tips are set to one end of gun body, gun body
It is internally provided with control module, the input terminal of control module is connect by inputting cable with charge power supply, the output of control module
End connects pipette tips by output cord.
The control module includes：Relay is the switching device of the charging gun；Controller controls relay contact
Break-make, receive and temperature sensor signal；Temperature sensor detects the temperature of relay.
If the temperature of relay is more than preset safe temperature in charging, controller can judge the work of relay at this time
Make that temperature is excessively high, and then send out the control signal of shutdown relay contact, then control relay contact shutdown, charging stops.
Temperature sensor continues to detect the temperature of relay during charging stops, when the temperature drops to the preset temperature for allowing to connect
When spending, controller sends out the control signal of closing relay contact, controls relay contact closure, restores charging.
The technical solution stops work by the temperature of detection integral type charging gun relay, under over-temperature conditions charging gun
Make, resume work automatically in the secure state, prevent relay operating temperature is excessively high from causing safety accident, circuit is simply and very
Reliably.
The technical solution of the utility model and effect will be further described in conjunction with attached drawing in a specific embodiment.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the signal flow diagram of the utility model control module.
Figure label：1- gun bodies；2- pipette tips；3- control modules；4- output cords；5- inputs cable.
Specific implementation mode
The utility model is described in further detail with reference to embodiment and attached drawing, but the implementation of the utility model
Mode is not limited to this.
Referring to Fig. 1, the utility model provides a kind of integral type charging gun with overheat protector, including gun body 1, pipette tips 2, defeated
Enter cable 5, output cord 4, the pipette tips 2 are set to one end of gun body 1, and gun body 1 is internally provided with control module 3, controls mould
The input terminal of block 3 is connect by inputting cable 5 with charge power supply, and the output end of control module 3 connects rifle by output cord 4
Head.
Referring to Fig. 2, the control module 3 includes：Relay is the switching device of the charging gun；Controller, control after
The break-make of appliance contact receives the signal with temperature sensor；Temperature sensor detects the temperature of relay.
The control module 3 carries out charging gun overheat protector by following below scheme：
A1, the integral type charging gun work on power, and temperature sensor detects the temperature of relay simultaneously, and handle detects
Temperature value be input to MCU as temperature signal；
The temperature signal that a2, MCU real-time reception temperature sensor are sent, and compared with the safe temperature pre-set.
If the temperature of temperature sensor detection is less than preset safe temperature, then it is assumed that relay is in safe work state, without
Processing；If the temperature of temperature sensor detection is greater than or equal to preset safe temperature, then it is assumed that the work of relay at this time
Temperature is excessively high, needs to execute protection act.
A3, controller MCU send out control signal, and relay contact is made to turn off, and charging stops；
A4, temperature sensor continue detect relay temperature, when relay temperature drop to it is preset allow connect
When temperature value, MCU judges that relay temperature has been restored to can normal working temperature；
A5, controller MCU send out control signal, and relay contact closure, charging is made to restore；
Indicate that temperature, Sig1 indicate that temperature sensor is sent to the temperature signal of controller MCU, Sig2 tables referring to Fig. 2, T
Show control signal of the controller to relay.The temperature signal Sig1 that MCU real-time reception temperature sensors are sent, and with set in advance
The safe temperature set compares, and when temperature is more than preset safe temperature, needs to take safeguard measure, and Sig2 is shutdown at this time
Signal, controller can be such that the contact of relay turns off to be stopped by the signal；It is dropped at a temperature of relay
Allow connect temperature when, MCU judge relay temperature restored to can normal working temperature, then send out control signal,
Make relay contact closure, thus Sig2 is to connect signal at this time, controller by the signal make the contact closure of relay from
And the electric current supply of restoring circuit works on.
More than, describe the embodiment of the utility model in detail with reference to attached drawing, but specific constitute is not limited to the reality
Mode is applied, further includes the design etc. for not departing from the utility model main scope.
