Abstract

An electrical connector is used to electrically connect a chip module to a circuit board. The electrical connector has an insulating body, provided with multiple accommodating holes vertically penetrating through the insulating body. An upper surface of the insulating body protrudes upward to form a protruding block located between adjacent ones of the accommodating holes to support the chip module. The protruding block has a first ejector pin surface. The insulating body has a second ejector pin surface adjacent to the protruding block. The first ejector pin surface and the second ejector pin surface are provided for an ejector pin on a mold to push thereon so as to push the insulating body out of the mold. Multiple terminals are correspondingly accommodated in the accommodating holes to be electrically connected to the chip module.

First claim

What is claimed is:

1. An electrical connector configured to electrically connect a chip module to a circuit board, comprising:
an insulating body, provided with a plurality of accommodating holes vertically penetrating through the insulating body, wherein an upper surface of the insulating body protrudes upward to form a protruding block located between adjacent ones of the accommodating holes and configured to support the chip module, the protruding block has a first ejector pin surface, the insulating body has a second ejector pin surface adjacent to the protruding block, and the first ejector pin surface and the second ejector pin surface are configured for an ejector pin on a mold to push thereon so as to push the insulating body out of the mold; and
a plurality of terminals, correspondingly accommodated in the accommodating holes and configured to be electrically connected to the chip module.

2. The electrical connector according to claim 1 , wherein the protruding block has a side surface located between the first ejector pin surface and the second ejector pin surface, and the first ejector pin surface and the second ejector pin surface are respectively located at two sides of the side surface.

3. The electrical connector according to claim 2 , wherein two opposite ends of the side surface are respectively connected with the first ejector pin surface and the second ejector pin surface.

4. The electrical connector according to claim 1 , wherein the protruding block has a first portion connected to the upper surface and a second portion protruding upward from the first portion.

5. The electrical connector according to claim 4 , wherein the first ejector pin surface is provided on the first portion.

6. The electrical connector according to claim 5 , wherein a third ejector pin surface is formed on an upper surface of the second portion and configured for the ejector pin to push thereon.

7. The electrical connector according to claim 5 , wherein the first ejector pin surface is located between the second portion and the second ejector pin surface.

8. The electrical connector according to claim 4 , wherein an upper surface of the first portion forms the first ejector pin surface.

9. The electrical connector according to claim 1 , wherein a plurality of protruding blocks and a plurality of first ejector pin surfaces are provided, and the first ejector pin surfaces are only provided on some of the protruding blocks.

10. The electrical connector according to claim 9 , wherein the insulating body has a plurality of second ejector pin surfaces, and a quantity of the second ejector pin surfaces is identical to a quantity of the first ejector pin surfaces.

11. The electrical connector according to claim 1 , wherein the second ejector pin surface is located between the protruding block and the accommodating holes.

12. The electrical connector according to claim 1 , wherein a recess is downward concavely provided on the upper surface of the insulating body, and the second ejector pin surface is formed on a bottom surface of the recess.

13. The electrical connector according to claim 12 , wherein the recess is adjacent to the protruding block.

14. The electrical connector according to claim 1 , wherein the protruding block has a supporting surface configured to support the chip module, and the first ejector pin surface and the supporting surface are staggeredly provided.

15. The electrical connector according to claim 1 , wherein the second ejector pin surface is located lower than the upper surface of the insulating body, and the first ejector pin surface is located higher than the upper surface of the insulating body.

16. An electrical connector configured to electrically connect a chip module to a circuit board, comprising:
an insulating body, provided with a plurality of accommodating holes vertically penetrating through the insulating body, wherein two adjacent ones of the accommodating holes are separated by a partition, the insulating body is provided with a protruding block protruding upward from the partition and configured to support the chip module, the protruding block is provided with a first ejector pin surface, the partition has a second ejector pin surface adjacent to the protruding block, and the second ejector pin surface and the first ejector pin surface are configured for an ejector pin to push thereon so as to push the insulating body out of a mold; and
a plurality of terminals, correspondingly accommodated in the accommodating holes and configured to be electrically connected to the chip module.

17. The electrical connector according to claim 16 , wherein the protruding block has a first portion connected to the partition and a second portion protruding upward from the first portion, and the first ejector pin surface is provided on the first portion.

18. The electrical connector according to claim 17 , wherein an upper surface of the first portion forms the first ejector pin surface.

19. The electrical connector according to claim 16 , wherein a plurality of protruding blocks and a plurality of first ejector pin surfaces are provided, the first ejector pin surfaces are only provided on some of the protruding blocks, the insulating body has a plurality of second ejector pin surfaces, and a quantity of the second ejector pin surface is identical to a quantity of the first ejector pin surface.

20. The electrical connector according to claim 16 , wherein a recess is downward concavely provided on the upper surface of the insulating body, the second ejector pin surface is formed on a bottom surface of the recess, and the recess is adjacent to the protruding block.
