Description

Technical Field

[0001] The utility model belongs to the field of data power line sets, and in particular relates to a Type-C power line set with a power-off anti-misbehavior function. Background Art

[0002] With the promotion of USB PD3.1 protocol, the power that Type-C interface needs to meet is getting larger and larger, up to 240W (48V / 5A), which greatly shortens the charging time and improves work efficiency; but at the same time, when Type-C is unplugged under such a high-power power supply, it is easy to produce sparks, burn the terminals, reduce the life of the equipment, and also bring safety hazards.

[0003] In view of this background, our company has found corresponding solutions for high-power power cables, which are summarized as follows:

[0004] 1. Add a power control switch on the Type-C end. When you want to unplug the device, long press the power control switch to disconnect the CC Pin. According to the PD protocol, after the CC Pin is disconnected, the Vbus is powered off and then unplugged to achieve the purpose of unplugging after power off.

[0005] 2. Add an LED display at the front end of the above power control switch. When the power control switch is pressed, the power is disconnected and the LED light goes out. When the mother socket is inserted and the switch is released, the power is restored and the light comes on to achieve the purpose of reminder;

[0006] The above two designs are based on the assumption that the user will normally press the switch to plug or unplug. When the consumer does not press the switch, it can still be unplugged and sparks will still occur, which is not completely fool-proof.

[0007] Therefore, a Type-C power cord set with a power-off prevention function is needed. Utility Model Content
