Abstract

An electrical connector is configured to electrically connect to a chip module, where a bottom surface of the chip module is provided with at least one conductive sheet. The electrical connector includes: an insulating body, configured to sustain the chip module, and provided with at least one accommodating hole penetrating through the insulating body vertically; and at least one terminal, correspondingly accommodated in the at least one accommodating hole, and having at least two elastic arms. Two inner sides of two adjacent elastic arms of the at least two elastic arms are protrudingly provided with two contact portions upward, so that each of the contact portions is located higher than an upper surface of each of the two adjacent elastic arms. An outer side of each elastic arm is spaced from each of the contact portions. The two contact portions upward abut a same conductive sheet of the chip module.

First claim

What is claimed is:

1. An electrical connector, configured to electrically connect to a chip module, wherein a bottom surface of the chip module is provided with at least one conductive sheet, the electrical connector comprising:
an insulating body, configured to sustain the chip module, and provided with at least one accommodating hole penetrating through the insulating body vertically; and
at least one terminal, correspondingly accommodated in the at least one accommodating hole, and having at least two elastic arms, wherein two inner sides of two adjacent elastic arms of the at least two elastic arms are protrudingly provided with two contact portions upward, so that each of the contact portions is located higher than an upper surface of each of the two adjacent elastic arms, an outer side of each of the two adjacent elastic arms is spaced from each of the contact portions, and the two contact portions upward abut a same conductive sheet of the at least one conductive sheet.

2. The electrical connector according to claim 1 , wherein each of the two adjacent elastic arms has a center line along an extending direction thereof, and each of the contact portions is provided at one side of the center line.

3. The electrical connector according to claim 1 , comprising a plurality of terminals, wherein the two adjacent elastic arms are provided at two of the terminals.

4. The electrical connector according to claim 1 , wherein:
each of the at least one terminal has a flat plate-shaped connecting portion;
the two adjacent elastic arms are formed by bending and extending upward from the connecting portion;
two conducting arms are formed by bending and extending downward from the connecting portion;
inner sides of the two conducting arms are protrudingly provided with two abutting portions downward, so that each of the abutting portions is located lower than a lower surface of each of the conducting arms;
an outer side of each of the conducting arms is spaced from each of the abutting portions; and
the two abutting portions downward abut a same conductive spacer of a circuit board.

5. The electrical connector according to claim 4 , wherein each of the abutting portions and each of the contact portions have a same structure.

6. The electrical connector according to claim 4 , wherein a flat plate-shaped retaining portion is formed by extending from each of two opposite sides of the connecting portion, each of two opposite sides of each accommodating hole is concavely provided with a retaining groove, and the retaining groove has a stopping surface located below the retaining portion to prevent each of the terminals from moving downward.

7. The electrical connector according to claim 4 , wherein each of the conducting arms has a center line along an extending direction thereof, and each of the abutting portions is provided at one side of the center line.

8. The electrical connector according to claim 1 , wherein a contour of each of the contact portions is a semicircle.

9. The electrical connector according to claim 1 , wherein a height of each of the contact portions gradually decreases along a direction from the inner side of the corresponding elastic arm to the outer side of corresponding elastic arm.

10. The electrical connector according to claim 1 , wherein the inner side of each of the two adjacent elastic arms is flush with an inner side of each of the contact portions.

11. The electrical connector according to claim 1 , wherein each of the contact portions extends to an end of each of the two adjacent elastic arms.

12. The electrical connector according to claim 1 , wherein at least one of the two adjacent elastic arms is bent toward another one of the two adjacent elastic arms, so that a distance between the two adjacent elastic arms decreases in a direction from bottom to top.

13. A terminal, configured to electrically connect to a chip module, wherein multiple conductive sheets are provided on a bottom surface of the chip module, the terminal comprising:
two elastic arms, wherein two adjacent inner sides of the two elastic arms are provided with two contact portions, the two contact portions upward abut a same conductive sheet of the conductive sheets, opposite outer sides of the two elastic arms are provided with two notches respectively, and the two notches are respectively connected to the two contact portions.

14. The terminal according to claim 13 , wherein each of the two elastic arms has a center line along an extending direction thereof, and each of the contact portions is provided at one side of the center line.

15. The terminal according to claim 13 , wherein at least one of the two elastic arms is bent toward another one of the two elastic arms, so that a distance between the two elastic arms decreases in a direction from bottom to top.

16. The terminal according to claim 13 , wherein each of the notches penetrates through the corresponding elastic arm to an end of the corresponding elastic arm.

17. The terminal according to claim 16 , wherein each of the contact portions extends to the end of the corresponding elastic arm.

18. The terminal according to claim 13 , wherein each of the notches penetrates through the corresponding elastic arm in a vertical direction.

19. The terminal according to claim 13 , wherein a bottom surface of each of the notches is inclined to an upper surface of the corresponding contact portions.

20. The terminal according to claim 13 , wherein the two elastic arms are folded outward to form the two contact portions.
