Electrical connector

An electrical connector comprising:

• an array of terminals arranged side-by-side in a horizontal direction, each of the terminals of the array having a first connection portion adapted to be connected with a first one of two members electrically connectable to each other via the electrical connector, and a second connection portion adapted to be connected with a second one of the two members;
• and a grounding plate, wherein:
• two or more first terminals consisting of a part of the terminals of the array are arranged such that an inter-terminal pitch in the first connection portions thereof is equal to that in the second connection portions thereof;
• two or more second terminals consisting of the remaining terminals of the array other than the first terminals are arranged such that an inter-terminal pitch in the first connection portions thereof is less than that in the second connection portions thereof;
• and
• the first member includes a printed circuit board, and an external shell attached to the printed circuit board,
• wherein the electrical connector is designed such that, when the first member is attached to the electrical connector, the first connection portions of the terminals of the array are brought into contact with the printed circuit board, and the grounding plate is brought into contact with the external shell in a vicinity of the first connection portions of the terminals of the array so as to be connected to ground.

An electrical connector comprising a plurality of terminals arranged side-by-side in a horizontal direction, each of the terminals having a first connection means for connecting with one of two members electrically connectable to each other via the electrical connector, and a second connection means for connecting with the other of the two members, wherein:

• two or more first terminals consisting of a part of the terminals are arranged such that an inter-terminal pitch in the first connection means is equal to that in the second connection means;
• two or more second terminals consisting of the remaining terminals other than the first terminals are arranged such that an inter-terminal pitch in the first connection means is less than that in the second connection means;
• the plurality of terminals include an upper array of terminals arranged side-by-side in the horizontal direction, and a lower array of terminals arranged side-by-side in the horizontal direction and disposed on a lower side of the upper array in a vertical direction, each of the terminals of the upper and lower arrays having a first connection portion adapted to be connected with one of two members electrically connectable to each other via the electrical connector, and a second connection portion adapted to be connected with the other member;
• two or more first terminals consisting of a part of the terminals of the upper array are arranged such that an inter-terminal pitch in the first connection portions thereof is equal to that in the second connection portions thereof;
• two or more second terminals consisting of the remaining terminals of the upper array other than the first terminals are arranged such that an inter-terminal pitch in the first connection portions thereof is less than that in the second connection portions thereof;
• and
• all the terminals of the lower array are arranged such that an inter-terminal pitch in the first connection portions thereof is less than that in the second connection portions thereof.

An electrical connector comprising a plurality of terminals arranged side-by-side in a horizontal direction, each of the terminals having a first connection portion adapted to be connected with one of two members electrically connectable to each other via the electrical connector, and a second connection portion adapted to be connected with the other of the two members, wherein:

• two or more first terminals of the terminals are arranged such that an inter-terminal pitch in the first connection portions thereof is equal to that in the second connection portions thereof;
• two or more second terminals of the remaining terminals other than the first terminals are arranged such that an inter-terminal pitch in the first connection portions thereof is less than that in the second connection portions thereof;
• each of the first terminals linearly extends between the first and second connection portions thereof in the horizontal direction, and each of the second terminals has a bent portion which is bent between the first and second connection portions thereof in the horizontal direction;
• the first terminals are disposed in a central region, and the second terminals are disposed on opposite sides of the central region;
• and
• each of the first terminals has a width in the first direction greater than that of each of the second terminals.
