Module assembly and connector and electronic device

A module assembly comprising a plurality of modules, wherein the modules each comprise:

• a housing having a plurality of sides;
• at least one pin provided on a side of the housing, and configured to be in a first state in which the pin protrudes from the housing or a second state in which the pin is received in the housing;
• and
• at least one pin receiver provided on a side of the housing, and configured to receive a pin protruding from another module,
• wherein one of the modules is to be surface-to-surface coupled to another of the modules,
• wherein, when the one module is surface-to-surface coupled to the another module, a pin of the one module switches from the second state to the first state to be inserted into a pin receiver of the other module.

A connector for connecting with an electronic device, the connector comprising:

• a frame in which a pin receiver is formed such that a pin selectively protruding from the electronic device is to be inserted into the pin receiver;
• a magnet installed in the frame and configured to attract the pin into the pin receiver;
• and
• a terminal provided on a side of the frame, and to be connected to the electronic device via a conducting wire.

An electronic device to be connected with a connector, the electronic device comprising:

• a frame;
• a terminal connected to a substrate provided in the frame via a conducting wire and exposed to an outside;
• a pin configured to selectively protrude from the frame and be coupled to the connector;
• and
• a first magnet configured to maintain a state in which the pin is received in the frame,
• wherein the pin is attracted by a second magnet provided in the connector.
