Electronic device including printed circuit boards and slidable structure

An electronic device comprising:

• a housing including:
• a first housing part, and
• a second housing part configured to movably engage with the first housing part to provide a retracted state of the housing and an extended state of the housing, the second housing part including:
• a frame configured to accommodate a battery, and
• a slide cover at least partially surrounding the frame to accommodate the frame;
• a flexible display disposed at the first housing part and the second housing part such that a size of an area visible from a front side of the housing changes as a state of the housing is changed between the retracted state and the extended state, the flexible display including:
• a first portion visible to the front side of the housing, based on the housing being in the retracted state, and
• a second portion, not visible to the front side, at least partially positioned between the frame and the slide cover;
• a first printed circuit board (PCB) disposed at the first housing part;
• a second PCB disposed at the slide cover;
• and
• a third PCB disposed at the frame,
• wherein the second PCB is electrically connected to the first PCB through the third PCB,
• wherein the second PCB and the third PCB are electrically connected to each other at a space between a lateral side of the frame and a lateral side of the slide cover corresponding to the lateral side of the frame,
• wherein the first PCB and the third PCB are electrically connected to each other through a connecting member, the connecting member including a flexible portion at least partially deformable in response to a movement of the second housing part with respect to the first housing part, and
• wherein the second portion of the flexible display is configured to be inserted into a space between the second PCB and the third PCB, based on the state of the housing being changed from the extended state to the retracted state.
