Embodiment 1

[0061] Embodiment 1: the above-mentioned first input terminal is a non-inverting input terminal, and the thermistor is an NTC resistor.

[0062] After the user uses the charger or other power supply port to charge the mobile terminal, generally, the data cable is always kept on the power adapter or the power supply port.

[0063] (1) When the first interface of the data line is inserted into the power adapter, and the C port (second interface) is suspended, the voltage of the data line VBUS is 5V, and the gate (or base) of the Q2 tube is in a certain level state. (Some switch tubes need to add an external pull-up resistor to control the state of the pole), at this time, Q2 is in the off state; at the same time, because the gate-source voltage of Q1 tube is less than |Vgs1|, so Q1 tube is in the off state, and Vgs1 is Q1 tube Since the two input terminals of the comparator are composed of VBUS network voltage dividing resistors, among them, the voltage dividing voltage of the n...

Embodiment 2

[0069] Embodiment 2: the above-mentioned first input terminal is an inverting input terminal, and the thermistor is a PTC resistor.

[0070] After the user uses the charger or other power supply port to charge the mobile terminal, generally, the data cable is always kept on the power adapter or the power supply port.

[0071] (1) When the first interface of the data line is inserted into the power adapter, and the C port (second interface) is suspended, the voltage of the data line VBUS is 5V, and the gate (or base) of the Q2 tube is in a certain level state. (Some switch tubes need to add an external pull-up resistor to control the state of the pole), at this time, Q2 is in the cut-off state; at the same time, because the gate-source voltage of the Q1 tube is less than |Vgs1|, the Q1 tube is in the cut-off state, and Vgs1 is the Q1 tube Since the two input terminals of the comparator are composed of VBUS network voltage divider resistors, among them, the voltage divider resis...

Abstract

The invention provides a connector, which solves the problem that the power supply pin of the data line is charged for a long time and corrodes in an environment with high humidity. The first end of the connector has a first interface, the second end has a second interface, the second interface includes: a first switch unit, the first switch unit is connected in series between the power input end and the power output end of the second interface; Two switch units, the second switch unit is connected to the control terminal of the first switch unit and the ground pin of the second interface, and the ground pin of the second interface is connected to the preset reference voltage; disconnected from the device to be charged at the second interface When connected, the first switch unit is in an open circuit state. When the second interface is connected to the device to be charged, the ground pin of the second interface is connected to the ground pin of the device to be charged, the ground pin of the second interface is grounded, and the first The switch unit is in the ON state. When the connector of the present invention is not connected with the device to be charged, the second interface is in an uncharged state, thereby reducing the probability of pins being corroded.

Description

technical field [0001] The invention relates to the technical field of communication applications, in particular to a connector. Background technique [0002] With the development of high-current fast charging technology, most of the socket iron shells of the Universal Serial Bus (USB) interface are grounded. For Type C sockets, on the one hand, grounding can reduce charging interference and Interference during data transmission, especially in USB3.0 communication, the signal interference is very serious, requiring three-dimensional shielding measures for sending TX or receiving RX. On the other hand, grounding treatment can make the shielding layer and braided net form a loop, so that Share a part of the charging backflow, which is conducive to making the data line thinner. [0003] Under normal circumstances, the data line end is charged for a long time and exposed to the environment. The power pin will be corroded in a high humidity environment, causing foreign matter to...
