Abstract

An electrical connector includes an insulating body having multiple receiving slots, and multiple first terminals and multiple second terminals respectively received in the receiving slots. Each first terminal has a first connecting portion, a first elastic arm bending and upward extending from the first connecting portion, and a first conducting arm bending and extending from the first connecting portion. Each second terminal has a second connecting portion, a second elastic arm bending and extending upward from the second connecting portion, and a second conducting arm bending and extending from the second connecting portion. A bent position between each of the first connecting portions and a corresponding one of the first elastic arms is higher than a bent position between each of the second connecting portions and a corresponding one of the second elastic arms.

First claim

What is claimed is:

an insulating body for sustaining the chip module, comprising a plurality of rows of receiving slots running through the insulating body, the plurality of rows of receiving slots having equal row spacing; and
a plurality of first terminals and a plurality of second terminals, respectively received in the receiving slots,
wherein each of the first terminals comprises a first connecting portion, a first elastic arm bending and extending upward from one side of the first connecting portion, a first contact portion formed from a top of the first elastic arm and used for urging upward the chip module, and a first conducting arm bending and extending downward from the first connecting portion for conducting downward the circuit board;
wherein each of the second terminals comprises a second connecting portion, a second elastic arm bending and extending upward from one side of the second connecting portion, a second contact portion formed from a top of the second elastic arm and used for urging upward the chip module, and a second conducting arm bending and extending downward from the second connecting portion for conducting downward the circuit board;
wherein a bent position between each of the first connecting portions and a corresponding one of the first elastic arms and a bent position between each of the second connecting portions and a corresponding one of the second elastic arms are located on a same side, and the bent position between each of the first connecting portions and the corresponding one of the first elastic arms is higher than the bent position between each of the second connecting portions and the corresponding one of the second elastic arms; and
wherein heights of the first contact portions are the same as heights of the second contact portions, and heights of lowest points of the first conducting arms are equal to heights of lowest points of the second conducting arms.

2. The electrical connector according to claim 1 , wherein a bent position between each of the first connecting portions and a corresponding one of the first conducting arms is higher than a bent position between each of the second connecting portions and a corresponding one of the second conducting arms.

3. The electrical connector according to claim 1 , wherein in a horizontal direction, the first connecting portions are not overlapped with the second connecting portions, the first elastic arms are not overlapped with the second elastic arms, and the first conducting arms are not overlapped with the second conducting arms.

4. The electrical connector according to claim 1 , wherein structures of the first terminals are the same as structures, which are overturned up and down for 180 degrees, of the second terminals.

5. The electrical connector according to claim 1 , wherein the first terminals and the second terminals are respectively arranged in rows and arranged alternately, each two adjacent rows of the receiving slots are formed oppositely, directions of the first contact portions are consistent to directions of the second contact portions, and directions of the first conducting arms are consistent to directions of the second conducting arms.

6. The electrical connector according to claim 5 , wherein a row of other terminals are further arranged between each adjacent a row of first terminals and a row of second terminals, the other terminals are staggered with the first terminals and the second terminals, and structures of the other terminals are different from structures of the first terminals and the second terminals.

7. The electrical connector according to claim 1 , wherein the first terminals and the second terminals are respectively arranged in rows and arranged alternately, each two adjacent rows of the receiving slots are formed in a staggered manner, directions of the first contact portions are consistent to directions of the second contact portions, and directions of the conducting arms are consistent to directions of the second conducting arms.

8. The electrical connector according to claim 1 , wherein the first terminals and the second terminals are arrayed in a matrix, and the first terminals and the second terminals are alternately arranged in each row and each column of the receiving slots.

9. The electrical connector according to claim 1 ,
wherein for each of the first terminals, the first connecting portion is arc-shaped, the first elastic arm is formed by obliquely and upward extending along a straight line from the first connecting portion, the first contact portion is arc-shaped and is formed by bending and extending from the first elastic arm, the first conducting arm is formed by obliquely and downward extending along a straight line from the first connecting portion, a first conducting portion is arc-shaped, is used for urging the circuit board, and is formed at a tail end of the first conducting arm, and the first elastic arm and the first conducting arm are located at a same side of the first connecting portion;
wherein for each of the second terminals, the second connecting portion is arc-shaped, the second elastic arm is formed by obliquely and upward extending along a straight line from the second connecting portions, the second contact portion is arc-shaped and is formed by bending and extending from the second elastic arm, the second conducting arm is formed by obliquely and downward extending along a straight line from the second connecting portion, a second conducting portion is arc-shaped, is used for urging the circuit board, and is formed at a tail end of the second conducting arm, and the second elastic arm and the second conducting arm are located a same side of the second connecting portion; and
wherein a bent position between each of the first connecting portions and corresponding one of the first conducting arms is higher than a bent position between each of the second connecting portions and a corresponding one of the second elastic arms.

10. An electrical connector for electrically connecting a chip module and a circuit board, comprising:
an insulating body for sustaining the chip module, comprising a plurality of receiving slots running through the insulating body and arranged in a matrix; and
a plurality of first terminals and a plurality of second terminals respectively received in the receiving slots,
