## Abstract

A discharge circuit includes a power supply unit, a connector, and a jumper. The connector includes a number of pins defined in two rows with one of the pin is coupled to a power terminal provided by the power supply unit. The jumper is connected between the pin coupled to the power terminal and another pin connected to ground, to make the power terminal to discharge.

## Claims

### Claim 1

A discharge circuit, comprising:
a power supply unit comprising a first power terminal;
a jumper; and
a connector comprising first and second pins;
wherein the first pin of the connector is coupled to the first power terminal of the power supply unit, the second pin of the connector is connected to ground; the jumper is operable of being connected between the first pin and the second pin, to make the first power terminal to discharge.

### Claim 2 (depends on 1)

The discharge circuit of claim 1, wherein the second pin of the connector is connected to ground through a first resistor.

### Claim 3 (depends on 1)

The discharge circuit of claim 1, wherein the power supply unit further comprises a second power terminal, the connector further comprises a third pin and a fourth pin; the third pin of the connector is coupled to the second power terminal, the fourth pin is connected to ground; the jumper is operable of being connected between the third pin and the fourth pin.

### Claim 4 (depends on 3)

The discharge circuit of claim 3, wherein the fourth pin of the connector is connected to ground through a second resistor.
