The invention relates to the field of car rescue, in particular to a novel intelligent clip control panel for emergency ignition power supplies.
The relays in existing connecting wire clips of emergency power supplies are standard and universal parts which are installed as they are delivered. The pursuit of a small size of commercial relays leads to an inherent disadvantage that movable contacts may adhere to plastic shells at a high temperature and cannot be disconnected, in this case, the batteries of the emergency power supplies will be charged for a long time, and consequentially, the batteries will swell, burn out, and catch fire.
Existing intelligent clip control panels for emergency ignition power supplies comprise at least one relay which will generate excessive heat when working under a large current, and at this moment, the contact of the relay will be fused on the plastic shell next to the edge of the relay and cannot restore, thus resulting in a product failure.
The primary objective of the invention is to provide a novel intelligent clip control panel for emergency ignition power supplies to solve the problem that a contact of a relay in an intelligent clip control panel in the related art may be fused on a plastic shell next to the edge of the relay and cannot restore, thus resulting in a product failure.
To fulfill the above-mentioned objective, the invention provides a relay not provided with a shell. At least one relay is installed on a circuit board and has a contact including a first junction, a second junction, a third junction and a fourth junction which are connected to other circuits on the circuit board.
The invention further provides an intelligent clip control panel connected to an emergency power supply. The intelligent clip control panel comprises the relay and has one end connected to a first ignition clip through a connecting wire and the other end connected to a connecting port through a connecting wire, and the connecting port is inserted into an interface of the emergency power supply.
Preferably, the intelligent clip control panel further comprises a drive circuit and a microcontroller, the first junction is connected to a positive pole or a negative pole of the first ignition clip, the second junction is connected to a positive pole or a negative pole of the connecting port, the third junction is connected to a first path of the drive circuit, and the fourth junction is connected to a grounding path of the microcontroller.
Preferably, a second path of the drive circuit is connected to a first path of the microcontroller.
Preferably, the connecting port includes a first connecting port and a second connecting port, wherein the first connecting port is connected to a positive pole or a negative pole of the emergency power supply and is connected to a second path of the microcontroller through a current-limiting resistor, and the second connecting port is connected to the relay.
Preferably, the intelligent clip control panel further comprises an LED indicator light connected to a third path of the microcontroller.
Preferably, the intelligent clip control panel further comprises a buzzer connected to a fourth path of the microcontroller.
Preferably, the intelligent clip control panel further comprises a detection circuit having one end connected to the microcontroller and the other end connected to the relay.
The invention further provides an emergency power supply connector which comprises the intelligent clip control panel, a first ignition clip, a second ignition clip, and a connecting port and is used for connecting a car battery to an emergency power supply.
Preferably, the first ignition clip and the second ignition clip are connected to the car battery in a manner that poles of the first ignition clip and the second ignition clip correspond to poles of the car battery.
The invention has the following beneficial effects: the intelligent clip control panel comprises the relay without the shell; and the relay having the shell removed is directly installed on the circuit board of the intelligent clip control panel, so that the problem that the contact of the relay may be fused on a plastic shell next to the edge of the relay and cannot restore when the relay is electrified for use is solved, the relay is effectively prevented from being out of operation, and the relay and other electronic parts are protected.

According to the invention, the relay 11 having the shell removed is directly installed on the circuit board of an intelligent clip control panel, so that the problem that the contact of the relay 11 may be fused on a plastic shell next to the relay and cannot restore when the relay 11 is electrified for use is solved, the relay 11 is effectively prevented from being out of operation, and both the relay 11 and other electronic parts are protected.
