• and
• the second connector 200 comprises a connector insertion portion 211 having a shape of a rectangular section in such a manner as to be inserted into the insertion groove 101, connector concave portions 210a formed on the connector insertion portion 211 in such a manner as to be open toward the first connector 100 to insert the protruding portions 133, and a plurality of pins 220 arranged on both transverse sides of the connector concave portions 210a, so that if the protruding portions are inserted into the connector concave portions 210a, the plurality of pins 142 of the first connector 100 are arranged to face the plurality of pins 220 of the second connector 200, the first connector 100 comprising two outer members 110 facing each other, an intermediate member 120 located between the two outer members 110, the four pin modules 140 disposed between the intermediate member 120 and the outer members 110 on both transverse sides of the intermediate member 120, a top member 130 inserted into the outer members 110 on both transverse sides thereof in such a manner as to be disposed on top of the intermediate member 120, the two driving shafts 160 rotatably disposed between the intermediate member 120 and the outer members 110 under the top member 130 and having end portions protruding from one longitudinal side, and handles 170 disposed on the protruding end portions of the driving shafts 160,
• wherein each outer member 110 comprises:
• a plate-shaped outer member body 111;
• outer member side portions 113 formed on both ends of the plate-shaped outer member body 111 in such a manner as to protrude inward;
• outer member protrusion portions 115 protruding inward from tops of the outer member side portions 113, the outer members 110 facing each other being coupled to each other in such a manner as to allow the ends of the outer member protrusion portions 115 to come into contact with each other;
• body inner surfaces 111a inclinedly extended toward tops thereof;
• top member insertion grooves 111b concavely extended downward from the body inner surfaces 111a;
• outer member pin insertion grooves 111c extended downward from the top member insertion grooves 111b in such a manner as to be concavely spaced apart from the top member insertion grooves 111b;
• outer member axial grooves 113a extended on the outer member side portions 113 between the outer member protrusion portions 115 and the outer member protrusions 113e in the up and down direction;
• and outer member lower protrusions 113b extended more downward than the plate-shaped outer member body 111 from the outer member side portions 113 in such a manner as to form downward protruding surface and having PCB fastening holes 113f penetrated thereinto, and
• wherein the intermediate member 120 comprises:
• a plate-shaped intermediate member body 121;
• and intermediate member side portions 123 formed on both longitudinal ends of the intermediate member body 121, the intermediate member side portions 123 having intermediate member side protrusions 123h protruding from tops thereof, tops of the intermediate member side portions 123 protruding more upward than top of the intermediate member body 121, the intermediate member body 121 having first intermediate member surfaces 121c formed slantly on both transverse sides thereof in such a manner as to become increased in thickness from the top to the bottom and intermediate member pin insertion grooves 121a concavely formed spaced apart from the first intermediate member surfaces 121c in the down direction at positions facing the outer member pin insertion grooves 111c, and the intermediate member side portions 123 having PCB seating portions 123e formed by reducing thicknesses of the insides thereof in such a manner as to form inward and downward protruding surfaces, the PCB seating portions 123e having PCB fastening holes 123f penetrated thereinto, and intermediate member axial grooves 123a concavely formed on both transverse sides thereof in such a manner as to face the outer member axial grooves 113a, the first connector fastening holes 123g being penetrated in the up and down direction into the intermediate member side protrusions 123h.
