Abstract
The utility model relates to an electronic circuit, in particular to an automobile starter overheating protection device. A relay is in series connection between an ignition switch and an electromagnetic switch, and a control loop of the relay is respectively serially connected with a normally closed heat sensitive ferrite magnetic switch arranged inside the electromagnetic switch and a normally closed heat sensitive ferrite magnetic switch arranged inside a starting motor. The automobile starter overheating protection device has the advantages that the automobile starter overheating protection device utilizes the normally closed heat sensitive ferrite magnetic switches to protect by directly detecting the temperature of the starter, and can simultaneously monitor temperatures of the electromagnetic switch and the starting motor. Further, utilized heat sensitive ferrite materials have the advantages of high temperature control precision, anti-oxidation, corrosion resistance, reliability, durability, stable performance, low price and the like.
Description
Technical field
The utility model relates to a kind of electronic circuit, particularly relates to a kind of automobile starter over temperature protection system.
Background technology
The working current of starter is very big, in use can generate heat, and burns out the phenomenon of solenoid winding and actuating motor coil easily, causes the waste of coil copper wire.All the starter temperature is not directly measured and controlled in the fender guard of existing starter.
Summary of the invention
The purpose of this utility model is to increase a kind of over temperature protection system to automobile starter, and when the solenoid winding of starter or actuating motor are overheated, this device will work and disconnect the circuit of electromagnetic switch and actuating motor, play the effect of overheating protection.
For achieving the above object, technical solution of the present utility model is: relay is serially connected between ignition lock and the electromagnetic switch, has been connected in series respectively in its control loop to be arranged at the closed type heat sensitive ferrite magnetic switch in the electromagnetic switch and to be arranged at the interior closed type heat sensitive ferrite magnetic switch of actuating motor.Above-mentioned electromagnetic switch is made up of contact, locking coil, sucking coil etc.One end of ignition lock is connected with relay, and the other end is connected to power supply.
No matter be that the coil of electromagnetic switch is overheated or actuating motor is overheated, one in the closed type heat sensitive ferrite magnetic switch will disconnect, and make the control loop outage of relay, thereby make relay disconnect the electric current of solenoid winding, and then actuating motor also cuts off the power supply.This utility model plays a protective role by direct measurement starter temperature.
Automobile starter over temperature protection system of the present utility model can directly be added on the direct-drive type starter (no starting relay is used for minicar, car more), also can change a little single relay control formula starter circuit capable to form.
Advantage of the present utility model is:
Automobile starter over temperature protection system of the present utility model adopts closed type heat sensitive ferrite magnetic switch to play a protective role by the temperature of direct detection starter; and can monitor the temperature of electromagnetic switch and actuating motor simultaneously, the heat sensitive ferrite material that is adopted has accuracy of temperature control height, anti-oxidant, withstanding corrosion, reliability and durability, stable performance and advantage such as cheap.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
The specific embodiment
As shown in Figure 1; the utility model is a kind of new automobile starter fender guard, it by the locking coil (5) of power supply (1), ignition lock (2), relay (3), electromagnetic switch, sucking coil (6) and contact (4), be arranged at the closed type heat sensitive ferrite magnetic switch (7) in the electromagnetic switch, closed type heat sensitive ferrite magnetic switch (8) and the actuating motor (9) that is arranged in the actuating motor formed.
Relay (3) is serially connected between ignition lock (2) and the electromagnetic switch, has been connected in series respectively in its control loop to be arranged at the closed type heat sensitive ferrite magnetic switch (7) in the electromagnetic switch and to be arranged at closed type heat sensitive ferrite magnetic switch (8) in the actuating motor.
The principle of work of automobile starter over temperature protection system of the present utility model is:
During starting, ignition lock (2) is connected, and the control loop of relay (3) is connected, and relay (3) is connected the circuit of electromagnetic switch, electric current flow through respectively sucking coil (6) and locking coil (5); Flowing through is back to the negative pole of power supply (1) behind the direct minus earth of electric current of sucking coil (6), and the little electric current of the locking coil of flowing through (5) enters actuating motor (9) and makes it slow-speed; Simultaneously, under the effect of sucking coil (6) and locking coil (5), electromagnetic switch is connected contact (4), and big electric current directly enters actuating motor (9) by power supply (1) makes it fast commentaries on classics, the starter starting.
If in the start-up function process, no matter be the locking coil (5) of electromagnetic switch, sucking coil (6) is overheated, and still actuating motor (9) is overheated, one that is arranged in the interior closed type heat sensitive ferrite magnetic switch (7) of the electromagnetic switch closed type heat sensitive ferrite magnetic switch (8) interior with being arranged at actuating motor will disconnect, make the control loop outage of relay, at this moment, relay (3) will disconnect the locking coil (5) of ignition lock (3) and electromagnetic switch, electric current between sucking coil (6), and then the contact of electromagnetic switch (4) also will disconnect, the locking coil of electromagnetic switch (5), sucking coil (6) and actuating motor (9) all cut off the power supply and quit work, and avoid burning out because of overheated.
Of the present invention focusing on: 1) adopt closed type heat sensitive ferrite magnetic switch directly to measure the starter temperature and play superheat protecting function; 2) by the relay control circuit of two heat sensitive ferrite magnetic switch of serial connection, realize preventing simultaneously the overheated of solenoid winding and actuating motor.
Claims (2)
1, a kind of automobile starter over temperature protection system; it is characterized in that: relay (3) is serially connected between ignition lock (2) and the electromagnetic switch, has been connected in series respectively in its control loop to be arranged at the closed type heat sensitive ferrite magnetic switch (7) in the electromagnetic switch and to be arranged at the interior closed type heat sensitive ferrite magnetic switch (8) of actuating motor (9).
2, automobile starter over temperature protection system according to claim 1 is characterized in that: an end of ignition lock (2) is connected with power supply (1), and the other end connects the coil and the relay control circuit of relay (3) respectively.
