Description

Power converter components with terminal power detection function

technical field

The invention is a power converter component with the function of detecting terminal power, especially a power converter which can detect the output power that can be carried by the used power wire.

Background technique

The cigarette lighter in the cigarette lighter hole on the car is set up for drivers or passengers who need to smoke, but in order to meet the current high-tech rapid development of society and the consideration of health and car environment, the cigarette lighter hole changes the previous cigarette lighter. Instead, the heating function is used to provide power for some electrical products such as notebook computers, palmtop computers, audio-visual equipment, etc., so that users can use these electrical products in the car or charge them.

Please refer to Figure 55 and Figure 6, the cigarette lighter hole (not shown) used in the interior of a general car needs to pass the 12 volt (V) direct current in the car battery to a car through the cigarette lighter power lead (50). A power converter (40), and in the power converter (40), the DC power is converted into the AC power (110V/220V) required by the electrical products (not shown) connected to the power converter (40), It is then transmitted to electrical products, so that users can use these electrical equipment on the car conveniently. The power converter (40) has a power input socket (41), and the two ends of the cigarette lighter power lead (50) are inserted The terminal (52) of the power input socket (41) on the power converter (40) and the cigarette lighter plug (51) inserted into the cigarette lighter hole, and the general cigarette lighter power supply wire (50) can load 150 watts (W) power.

Please refer to Figure 77 and Figure 8. Generally, when the battery is used as a power source outside the car, the alligator clip power wire (60) is mostly used to directly connect the battery electrodes. The power supply and conversion method is the same as the above-mentioned cigarette lighter power wire ( 50) is the same, and the power converter (40) has a power input socket (41), and the two ends of the alligator clip power wire (60) are respectively inserted into the terminal (62) of the power input socket (41) and connected to the battery electrode The two alligator clips (61), the general alligator clip power lead (60) can bear the power above 200 watts (W).

Please refer to Fig. 55 to Fig. 8, the commonly used power converter (40) has a fixed output power, such as 150 watts and 200 watts, etc. Therefore, when using a power converter (40) with an output power above 200 watts Adopt the alligator clip power wire (60) as the power wire, but when this power converter (40) is used in the interior of the car, the power wire can only be changed into the cigarette lighter power wire (50) that can bear 150 watts, but because of this The power converter (40) still has an output power of more than 200 watts, so when the cigarette lighter power wire (50) is loaded with a power of more than 150 watts, the cigarette lighter connector (51) will overheat due to excessive current. Make the cigarette lighter joint (51) internal assembly damage, even can produce danger, or the fuse in the direct current output seat of the output power supply on the automobile burns out, so that the whole automobile needs to enter the factory for maintenance.

In view of the fact that the commonly used power converters cannot identify the power that the power wires used can withstand, resulting in damage to the internal components of the power wires, blowing the fuse of the power converter, making it impossible to use the DC socket or even causing danger, so after continuous attempts And hard work, finally created this power converter component with the function of detecting terminal power.

The purpose of this invention is to provide a power converter component that can detect the power that the power line can withstand to avoid damage to related components and eliminate danger.

In order to achieve the above purpose, the present invention has a power converter assembly with the function of detecting terminal power, which includes a power converter with an internal circuit and a power lead connected to the power converter and has an input socket, and the power The two ends of the wire are respectively the terminals inserted into the input socket and the joints connected to the power supply, which are characterized in that:

The side of the terminal opposite to the input socket has five output holes next to each other, and the input socket is provided with five coordination terminals that can be inserted into the input holes corresponding to the input holes, and the coordination terminals are connected to the inside of the power converter. The circuit is connected, and one of the coordination terminals is a detection terminal that can detect the power that the power supply wire can withstand.

Through the detection terminal, different signals from the power wires due to the current with different powers can be received, and the signals will be transmitted to the internal circuit of the power converter, so that the power converter can adjust the output current to avoid power wires Damage or danger to components due to excessive current.
