Shielded board to board electrical connector with surrounding shielding and electical device using the same

An electronic device comprising:

• a housing;
• a first substrate disposed in an inner space of the housing and comprising at least one electrical element;
• at least one receptacle disposed on the first substrate to at least partially surround the at least one electrical element,
• wherein the at least one receptacle comprises:
• at least one receptacle base comprising a recess,
• wherein the at least one receptacle base comprises:
• a first sidewall disposed adjacent to the at least one electrical element through the recess,
• a second side wall spaced outward from the first sidewall through the recess, and
• an island area protruding in the recess along a longitudinal direction,
• wherein the recess comprises:
• a first recess disposed between the island area and the first s sidewall, and
• a second recess disposed between the island area and the second side wall,
• first multiple conductive terminals arranged at a predetermined interval from at least a portion of the first sidewall to at least a portion of the first recess,
• second multiple conductive terminals arranged at a predetermined interval from at least a portion of the island area to at least a portion of the first recess,
• third multiple conductive terminals arranged at a predetermined interval from at least a portion of the second side wall to at least a portion of the second recess, and
• fourth multiple conductive terminals arranged at a predetermined interval from at least a portion of the island area to at least a portion of the second recess;
• and
• at least one connector detachably coupled to the at least one receptacle,
• wherein the at least one connector comprises:
• at least one connector base comprising an island seating portion on which the island area is seated, a third side wall disposed to face the first recess, and a fourth side wall disposed to face the second recess,
• first multiple connector terminals arranged on at least a portion of the third side wall and elastically coupled to the first multiple conductive terminals,
• second multiple connector terminals arranged on at least a portion of the third side wall and elastically coupled to the second multiple conductive terminals,
• third multiple connector terminals arranged on at least a portion of the fourth side wall and elastically coupled to the third multiple conductive terminals, and
• fourth multiple connector terminals arranged on at least a portion of the fourth side wall and elastically coupled to the fourth multiple conductive terminals, and
• wherein at least one multiple conductive terminal from among the first, the second, the third, and the fourth multiple conductive terminals is electrically connected to a ground of the first substrate,
• wherein, when the at least one connector is connected to the at least one receptacle, each of the first, second, third and fourth multiple conductive terminals is configured to have an individual electrical connection with respective individual first, second, third and fourth multiple connector terminals,
• wherein the first multiple connector terminals each forms an individual connection with the first multiple conductive terminals and the second multiple connector terminals each forms an individual connection with the second multiple conductive terminals within the first recess, and
• wherein the third multiple connector terminals each forms an individual connection with the third multiple conductive terminals and the fourth multiple connector terminals each forms an individual connection with the fourth multiple conductive terminals within the second recess separate from the first recess.
