Description of the invention: [Technical field to which the invention belongs] The present invention relates to a battery for connecting a cable to a battery in a vehicle, especially a vehicle battery cross with a reminder to incorrectly connect a battery electrode. Connect the cable device. [Prior art] The conductor and battery connector will be marked with color or symbol #, but the jumper cable and battery connector-once contaminated with sludge or in an environment with insufficient light When viewing the line, you must accurately confirm the polarity of the electrodes connected to the power supply battery and the battery to be aided. If the polarity of the electrodes is incorrectly connected, the battery and some components of the car will be damaged or burned. Although, the general use of the jumper wire may not be able to correctly identify the conductor with a specific polarity, so it may cause a situation of misconnection before. The patent case No. 4,769,586 of Wu Guo discloses a jumper cable device that can automatically identify the polarity of the battery (12) (14). As shown in the third figure, it contains a cable for connecting two batteries (12 ) (14) The two conductor pairs (16) (18). During installation, the jumper cable device uses the current value of the two pairs of conductors (16) (18) to identify the electrode polarity of the battery (12) (and performs a switching action. If the identification is successful, the first battery ( The two electrodes of I?) Will be correctly coupled to the second battery (14) ^ two electrodes. Because the jumper k-line device (10) uses the means of detecting the voltage on the conductor pair (丨 6) (18) to Identifies the polarity of the electrodes, so it is necessary to periodically detect the current condition on the conductor pair (1 6) (1 8), and during the detection, use more complex switching circuits to switch multiple, group relays, (36), and increase crossover The production cost of the winding, in addition, because this jumper cable device (10) has been installed for 1238556, it takes a lot of time to detect the connection state of the two pairs of clamps (2 2 _ 2 5) at each end of the conductor It is more complicated to use. It is based on 'The applicant was approved for publicity on July 17, 2000-US Patent No. 6,262,492, which proposes a method to improve the design of the above-mentioned US specialists. Car jumper cable device, which provides a simple and safe car The jumper cable can be used to connect the electrode of the battery gold power source with the same polarity to the rescue ground. However, this relay cable will burn the relay when the charging current is too large under non-positive 2 use conditions. …, The method works correctly, so we ask people to address this _ disadvantage, and then redesign a new and more convenient car battery jumper cable. [Summary of the Invention] ^ ^ ㈣ The main technology is to provide- It can be detected that the power supply 2 = the battery battery jumper cable for the battery battery is connected correctly: Electricity: The battery jumper I line device has a relatively low cost and a simple line: for! = When the user's incorrect use causes the relay to short circuit It can still be used as a battery jumper cable. The main jumper cable device used to achieve the above purpose includes the following: "The technician needs to order the battery door changer for the vehicle, which consists of an exciting coil and a switch.

Until the current detector detects that the charging current is greater than a certain value, the relay is maintained in a short-circuit state; —Battery polarity reverse warning circuit, which is connected between the battery electrode of the rescue battery and the battery electrode, when the battery electrode is connected to either end of the I line When the polarity is reversed, a warning sound will be issued;-the battery indicator for the battery to be aided is mainly composed of a light emitting diode whose anode and cathode are connected to the positive and negative electrode ports of the battery to be aided; and 'A power supply battery is connected to the indicator light, which is mainly composed of a light-emitting diode. The anode and cathode of the light-emitting diode are connected to the positive and negative electrodes 供电 of the power supply battery, respectively. The above relays are connected in series between the electrode terminals of the rescue battery and the electrode terminals of the power supply battery. Therefore, after the battery polarity detection circuit detects that the electrode polarities of the battery to be aided and the power supply battery are correctly connected, the signal oscillator operates as described above For this reason, the signal oscillator will control the 1238556 battery charging procedure in accordance with the current charging current status as a safe charging protection. #Charging current is abnormal.

A thunderbolt such as a man, electricity, and electricity, if this-the power supply current is greater than the yellow relay When the excitation current of RL2), the magnetic relay (RL2's switch (SW2) will make the 555 vibrate 15§ (^ surplus state (U 1) oscillating enable terminal here) and continue to output-high potential to the pole relay (10) Continuously conducting and charging operation. ^ When the battery and the backup battery start to charge, the current (such as the vehicle starting the engine exceeds the normal # ^ r Τ π ,, shirt) makes the current too large, and will continue to-(1 ◦) The invention of the contact switch of the switch (SW1) still has the same function as a jumper cable. After the battery electrode is disconnected, the relay (/ xian battery and the standby battery and the backup battery f will be turned on, so that * The above description shows that the present invention provides two: the secondary battery and the backup battery. The user correctly connects the electrode to be bottled to 'smoothly charge. Although the main components of the circuit 1238556 are burned due to excessive abnormal current, the invention still Can be used as a -π crossover cable. In addition, the present invention uses the signal oscillator system mainly for the purpose of providing safety and emergency rescue. Generally, the four electrode ports of the cable are of a chuck type design, so it is very likely that the two battery terminals will be clamped after the electrodes are correctly connected. The head is loose and it is short-circuited with the other chuck. At this time, the current detection circuit will cause the signal oscillation circuit to recover the output oscillation signal because of the supply current. When the oscillation signal is at a low potential, the The optocoupler crystal of the photocoupler will not generate current, and because the chuck is loose, the light emitting diode of the photocoupler no longer conducts light. Therefore, as long as the signal oscillator outputs a high potential, the optical coupling The relay is no longer conducting, so that the relay is no longer shorted. In this way, the present invention can indeed provide the effect of a safe emergency power supply.
