Abstract

An electrical connector for electrically connecting a chip module to a circuit board includes: a body, configured to upward support the chip module, where the body is provided with a plurality of accommodating holes; and multiple terminals, respectively accommodated in the accommodating holes correspondingly. Each of the terminals includes a flat plate portion along a vertical direction and a connecting portion connected to the flat plate portion. An elastic arm is formed by bending and extending from at least one end of the connecting portion so as to abut the chip module or the circuit board. When the chip module presses the terminal downward, a side edge of the elastic arm abuts the flat plate portion. The structure of an elastic arm can be simplified to reduce the processing difficulty thereof.

First claim

What is claimed is:

1. An electrical connector, configured to electrically connect a chip module to a circuit board, comprising:
a body, configured to upward support the chip module, wherein the body is provided with a plurality of accommodating holes; and
a plurality of terminals, respectively accommodated in the accommodating holes correspondingly, each of the terminals comprising a flat plate portion along a vertical direction and a connecting portion connected to the flat plate portion, wherein an elastic arm is formed by bending and extending from at least one end of the connecting portion so as to abut the chip module or the circuit board, and when the chip module presses the terminal downward, a side edge of the elastic arm abuts the flat plate portion.

2. The electrical connector of claim 1 , wherein the flat plate portion is formed by extending from one side of the connecting portion, a position limiting portion is formed by extending from an opposite side of the connecting portion, and each of the accommodating holes is protrudingly provided with a first protruding block on one side surface thereof and located below the position limiting portion so as to limit the corresponding terminal from moving downward.

3. The electrical connector of claim 2 , wherein the flat plate portion, the connecting portion and the position limiting portion are located on a same vertical plane.

4. The electrical connector of claim 1 , wherein the flat plate portion has a stopping portion located higher than a connecting position between the flat plate portion and the connecting portion, each of the accommodating holes has a stopping surface located below the stopping portion so as to limit the corresponding terminal from moving downward, and the elastic arm abuts a side of the flat plate portion away from the stopping portion.

5. The electrical connector of claim 1 , wherein the flat plate portion has a hook portion located lower than a connecting position between the flat plate portion and the connecting portion, each of the accommodating holes is protrudingly provided with a second protruding block on one side surface thereof and is located above the hook portion so as to limit the corresponding terminal from moving upward, and the elastic arm abuts a side of the flat plate portion away from the hook portion.

6. The electrical connector of claim 1 , wherein a side edge of the elastic arm is protrudingly provided with an abutting portion, and a side edge of the abutting portion abuts the flat plate portion.

7. The electrical connector of claim 6 , wherein there are two elastic arms, defined as a first elastic arm and a second elastic arm; the first elastic arm is formed by bending and extending upward from an upper end of the connecting portion and is configured to abut the chip module, and the second elastic arm is formed by bending and extending downward from a lower end of the connecting portion and is configured to abut the circuit board; a side edge of the first elastic arm is protrudingly provided with a first abutting portion; and when the chip module presses the first elastic arm downward, the first elastic arm and the second elastic arm abut each other, and the first abutting portion is located higher than an abutting position between the first elastic arm and the second elastic arm.

8. The electrical connector of claim 7 , wherein a side edge of the second elastic arm is protrudingly provided with a second abutting portion, and the second abutting portion of the second elastic arm is located lower than the abutting position between the first elastic arm and the second elastic arm.

9. The electrical connector of claim 1 , wherein the connecting portion is perpendicular to the flat plate portion, two elastic arms are formed by bending and extending from two opposite ends of the connecting portion respectively, and the two elastic arms are located on a same side of a vertical plane where the flat plate portion is located.

10. The electrical connector of claim 9 , wherein each of the elastic arms extends from one of the ends of the connecting portion toward a direction away from a vertical plane where the connecting portion is located, and then reversely bends and extends across the vertical plane where the connecting portion is located, and the two elastic arms are symmetrically disposed.

11. The electrical connector of claim 1 , wherein the elastic arm has an abutting portion abutting the flat plate portion, and a width of the elastic arm is gradually reduced from the abutting portion to a free end of the elastic arm, such that a guide chamfer is formed at a side edge of the elastic arm so as to guide the abutting portion to abut the flat plate portion.

12. The electrical connector of claim 1 , wherein the flat plate portion comprises a base, an extending portion extending from one side of the base and connected to the connecting portion, and a blocking portion protruding from an opposite side of the base, and each of the accommodating holes is protrudingly provided with a third protruding block and a fourth protruding block on one side surface thereof and are correspondingly located below the blocking portion and the extending portion so as to limit the corresponding terminal from moving downward.

13. The electrical connector of claim 12 , wherein two barbs are formed on two opposite sides of a bottom end of the base and are located below the third protruding block and the fourth protruding block, and one side of the third protruding block and one side of the fourth protruding block are respectively provided with an inclined surface so as to guide the barbs.

14. The electrical connector of claim 12 , wherein a height of the extending portion is between upper and lower edges of the blocking portion.

15. The electrical connector of claim 1 , wherein a side edge of the elastic arm abuts a plate surface of the flat plate portion.

16. The electrical connector of claim 1 , wherein a side edge of the elastic arm abuts a plate edge of the flat plate portion.

17. The electrical connector of claim 1 , wherein each of the terminals further comprises a bonding portion, the bonding portion and the connecting portion are formed by bending and extending from two opposite sides of the flat plate portion respectively, the bonding portion and the connecting portion are located on a same side of a vertical plane where the flat plate portion is located, an upper arm is formed by bending and extending upward from a top end of the bonding portion, the elastic arm is formed by bending and extending upward from the top end of the connecting portion and is configured to abut the chip module upward, and when the chip module presses the elastic arm downward, the elastic arm abuts the upper arm.

18. The electrical connector of claim 17 , wherein a free end of the elastic arm extends across a vertical plane where the bonding portion is located, and the free end of the elastic arm abuts the upper arm.

19. An electrical connector, configured to electrically connect a chip module to a circuit board, comprising:
a body, configured to upward support the chip module, wherein the body is provided with a plurality of accommodating holes; and
a plurality of terminals, respectively accommodated in the accommodating holes correspondingly, each of the terminals comprising a flat plate portion and a connecting portion connected to the flat plate portion, wherein the flat plate portion is disposed along a vertical direction and configured to be connected to a strip, an elastic arm is formed by bending
