Abstract

The present disclosure discloses an electrical connector which comprises a shell, a first wafer group and a second wafer group. The shell comprises: a first frame portion defining a first slot; a second frame portion defining a second slot; a first supporting portion positioned at a first side of the shell; a second supporting portion positioned at a second side of the shell, and a bridging portion connecting the first frame portion and the second frame portion. The bridging portion, the first frame portion and the second frame portion cooperatively define an air flow channel. The first wafer group is assembled to the first slot. The second wafer group is assembled to the second slot.

First claim

What is claimed is:

1. An electrical connector, comprising:
a shell, comprising:
a first frame portion defining a first slot;
a second frame portion defining a second slot;
a bridging portion connecting the first frame portion and the second frame portion, the bridging portion, the first frame portion and the second frame portion cooperatively defining an air flow channel;
a first supporting portion positioned at a first side of the shell; and
a second supporting portion positioned at a second side of the shell, the second side being opposite to the first side;

a first wafer group assembled to the first slot; and
a second wafer group assembled to the second slot, wherein each of the first wafer group and the second wafer group comprises a first wafer and a second wafer, each of the first wafer and the second wafer comprises a wafer housing, the wafer housing has a mounting face and a mating face, the mounting face is perpendicular to the mating face.

2. The electrical connector of claim 1 , wherein the shell has a mounting end and a mating end, the mounting end and the mating end are opposite to each other, each of the first slot and the second slot extends to the mounting end and the mating end of the shell.

3. The electrical connector of claim 1 , wherein the first wafer group and the second wafer group are respectively assembled to the first slot and the second slot by the mating faces of the wafer housings from the mounting end of the shell.

4. The electrical connector of claim 3 , wherein each of the first wafer and the second wafer further comprises terminals, each of the terminals has a mounting portion and a mating portion, the mounting portion of each of the terminals is positioned at the mounting face of the wafer housing, and the mating portion of each of the terminals is positioned at the mating face of the wafer housing and electrically connected to a card edge module.

5. The electrical connector of claim 4 , wherein the mating portions of the terminals of the first wafer and the mating portions of the terminals of the second wafer in the first wafer group are respectively positioned at two sides of the first slot.

6. An electrical connector, comprising:
a shell, comprising:
a first frame portion defining a first slot;
a second frame portion defining a second slot;
a bridging portion connecting the first frame portion and the second frame portion, the bridging portion, the first frame portion and the second frame portion cooperatively defining an air flow channel;
a first supporting portion positioned at a first side of the shell; and
a second supporting portion positioned at a second side of the shell, the second side being opposite to the first side;

a first wafer group assembled to the first slot; and
a second wafer group assembled to the second slot, wherein the first supporting portion is close to the mating end of the shell relative to the second supporting portion, and the second supporting portion is close to the mounting end of the shell relative to the first supporting portion.

7. The electrical connector of claim 6 , wherein a bottom surface of the first supporting portion and a bottom surface of the second supporting portion are flush with a bottom surface of the first frame portion and a bottom surface of the second frame portion.

8. The electrical connector of claim 6 , wherein a bottom surface of the bridging portion is flush with a bottom surface of the first frame portion and a bottom surface of the second frame portion.

9. The electrical connector of claim 6 , wherein
the bridging portion is higher than a bottom surface of the first frame portion and a bottom surface of the second frame portion;
the bridging portion, the first frame portion and the second frame portion define another air flow channel below a bottom surface of the bridging portion.

10. The electrical connector of claim 6 , wherein the bridging portion has an arch guide surface along a card insertion direction in which a card edge module is inserted into the first slot.

11. The electrical connector of claim 1 , wherein when the electrical connector is electrically connected to a card edge module and a circuit board, an extending direction of a card edge of the card edge module and an extending direction of a board edge of the circuit board are orthogonal to each other.

12. The electrical connector of claim 1 , wherein each of the first supporting portion and the second supporting portion has a screw hole extending upwardly from a bottom surface of each of the first supporting portion and the second supporting portion, a circuit board independent of the electrical connector has a through hole corresponding to the screw hole.

13. An electrical connector, comprising:
a shell, comprising:
a first frame portion defining a first slot;
a second frame portion defining a second slot;
a bridging portion connecting the first frame portion and the second frame portion, the bridging portion, the first frame portion and the second frame portion cooperatively defining an air flow channel;
a first supporting portion positioned at a first side of the shell; and
a second supporting portion positioned at a second side of the shell, the second side being opposite to the first side;

a first wafer group assembled to the first slot; and
a second wafer group assembled to the second slot, wherein each of the first frame portion and the second frame portion further comprises an extension portion, the extension portion is immediately adjacent to the mating end of the shell, and is formed by extending downwardly from a bottom surface of each of the first frame portion and the second frame portion, a bottom surface of the extension portion is lower than a bottom surface of the first supporting portion and a bottom surface of the second supporting portion.
