Electronic device and method for inspecting cable connection circuit of electronic device

A method of inspecting a cable connection circuit of an electronic device,

• wherein the cable connection circuit comprises:
• a first printed circuit board comprising a first antenna, a first connector connected to the first antenna, a second antenna, and a second connector connected to the second antenna;
• a second printed circuit board spaced apart from the first printed circuit board and comprising a power management circuit, a third connector electrically connected to the first connector, a fourth connector electrically connected to the second connector, a first detection circuit, and a processor operatively connected to the first detection circuit;
• a first cable configured to electrically connect the first connector and the third connector;
• and
• a second cable configured to electrically connect the second connector and the fourth connector,
• wherein the first detection circuit comprises a first resistor positioned between the processor and the power management circuit, and
• wherein the first printed circuit board comprises:
• a second resistor branching off between the first antenna and the first connector and electrically connected to the ground, and
• a third resistor branching off between the second antenna and the second connector and electrically connected to the ground,
• the method comprising:
• supplying a first voltage to the first antenna and the second antenna by using the power management circuit, and
• determining whether the first cable and the second cable are engaged based on voltage values measured by using the first detection circuit.

One or more non-transitory computer-readable storage media storing computer-executable instructions that, when executed by one or more processors of an electronic device, cause the electronic device to perform operations of inspecting a cable connection circuit of the electronic device,

• wherein the cable connection circuit comprises:
• a first printed circuit board comprising a first antenna, a first connector connected to the first antenna, a second antenna, and a second connector connected to the second antenna;
• a second printed circuit board spaced apart from the first printed circuit board and comprising a power management circuit, a third connector electrically connected to the first connector, a fourth connector electrically connected to the second connector, a first detection circuit, and a processor operatively connected to the first detection circuit;
• a first cable configured to electrically connect the first connector and the third connector;
• and
• a second cable configured to electrically connect the second connector and the fourth connector,
• wherein the first detection circuit comprises a first resistor positioned between the processor and the power management circuit, and
• wherein the first printed circuit board comprises:
• a second resistor branching off between the first antenna and the first connector and electrically connected to the ground, and
• a third resistor branching off between the second antenna and the second connector and electrically connected to the ground,
• the operations comprising:
• supplying a first voltage to the first antenna and the second antenna by using the power management circuit, and
• determining whether the first cable and the second cable are engaged based on voltage values measured by using the first detection circuit.
