Connecting assembly and electronic device including the same

An electronic device, comprising:

• a first housing including a first printed circuit board (PCB);
• a second housing configured to slide relative to the first housing in a first sliding direction and a second sliding direction opposite the first sliding direction and including a second printed circuit board (PCB);
• a flexible display comprising a display area configured to expand or reduce based on a sliding direction of the second housing relative to the first housing;
• and
• a flexible printed circuit board (FPCB) configured to electrically connect the first PCB and the second PCB and to expand based on the second housing sliding in the second direction or to contract based on the second housing sliding in the first direction, the FPCB including:
• a first portion having a rigid material and defining a bending reference,
• a second portion connected to the first portion and the first PCB, and configured to bend relative to the first portion in a first bending direction via a first flexible portion between the second portion and the first portion, and
• a third portion connected to the first portion and the second PCB, and configured to bend relative to the first portion in a second bending direction opposite to the first bending direction via a second flexible portion between the third portion and the first portion,
• wherein the first flexible portion and the second flexible portion are positioned on opposite sides of the bending reference defining independent flexible joints so that the second portion and the third portion are bendable about the first portion in mutually opposite directions while maintaining electrical continuity through the first portion,
• wherein the second portion and the third portion extend from the first portion in the same extending direction, and
• wherein based on the second housing sliding in the first sliding direction, the second portion and the third portion move closer to each other, and based on the second housing sliding in the second sliding direction, the second portion and the third portion move away from each other.
