Abstract

A backplane connector includes a housing, a number of terminal modules and a number of metal shield surrounding members. The housing includes a number of insulating protrusions. Each metal shield surrounding member includes a surrounding portion and a mounting portion. The surrounding portion includes a first side wall, a second side wall, a third side wall and a fourth side wall which are enclosed to form a fully-enclosed shielding cavity to at least partially sleeve over a corresponding insulating protrusion. The mounting portion is of a U-shaped configuration and includes a connecting portion connected to the third side wall, a first bending portion bent from one side of the connecting portion, and a second bending portion bent from another side of the connecting portion. The first bending portion is separated from the second side wall. The second bending portion is separated from the fourth side wall.

First claim

What is claimed is:

1 . A backplane connector, comprising:
a housing comprising a base, a first side wall portion extending from one end of the base, and a second side wall portion extending from another end of the base; the base, the first side wall portion and the second side wall portion jointly forming a receiving space for at least partially receiving a mating connector; the base defining a positioning groove in communication with the receiving space; a plurality of insulating protrusions protruding into the receiving space; a plurality of terminal modules, each terminal module being assembled to a corresponding insulating protrusion; and a plurality of metal shield surrounding members, each metal shield surrounding member being sleeved on the corresponding insulating protrusion; wherein the metal shield surrounding member comprises a surrounding portion and a mounting portion extending from the surrounding portion along a first direction; the surrounding portion comprises a first side wall, a second side wall, a third side wall and a fourth side wall; the first side wall is disposed opposite to the third side wall; the second side wall is disposed opposite to the fourth side wall; the first side wall, the second side wall, the third side wall and the fourth side wall are enclosed to form a fully-enclosed shielding cavity to at least partially sleeve over the corresponding insulating protrusion; the mounting portion is of a U-shaped configuration and is at least partially inserted in the positioning groove; the mounting portion comprises a connecting portion connected to the third side wall, a first bending portion bent from one side of the connecting portion, and a second bending portion bent from another side of the connecting portion; the first bending portion and the second side wall are disposed on a first same side of the metal shield surrounding member, while the first bending portion is separated from the second side wall along the first direction; and the second bending portion and the fourth side wall are disposed on a second same side of the metal shield surrounding member, while the second bending portion is separated from the fourth side wall along the first direction.

2 . The backplane connector according to claim 1 , wherein each metal shield surrounding member is of a one-piece configuration, and the mounting portion integrally extends from the surrounding portion along the first direction.

3 . The backplane connector according to claim 1 , wherein the connecting portion is flush with the third side wall.

4 . The backplane connector according to claim 1 , wherein the first bending portion protrudes outwardly beyond the second side wall along a direction away from the fourth side wall.

5 . The backplane connector according to claim 1 , wherein the second bending portion protrudes outwardly beyond the fourth side wall along a direction away from the second side wall.

6 . The backplane connector according to claim 1 , wherein the first bending portion is in parallel with the second side wall; the second bending portion is in parallel with the fourth side wall; and a distance between the first bending portion and the second bending portion is greater than a distance between the second side wall and the fourth side wall.

7 . The backplane connector according to claim 1 , wherein the mounting portion comprises a first tail portion extending from the first bending portion along the first direction, and a second tail portion extending from the second bending portion along the first direction;
wherein the first tail portion and the second tail portion are configured to be mounted to a circuit board.

8 . The backplane connector according to claim 1 , wherein the plurality of insulating protrusions integrally extend from the base.

9 . The backplane connector according to claim 1 , wherein each terminal module comprises a first signal terminal and a second signal terminal; and
wherein each insulating protrusion defines a first terminal receiving hole to receive the first signal terminal and a second terminal receiving hole to receive the second signal terminal.

10 . The backplane connector according to claim 9 , wherein the first signal terminal comprises a first contact portion residing in the first terminal receiving hole, and the first contact portion has a two-half structure and comprises a first contact piece, a second contact piece, and a first insertion hole located between the first contact piece and the second contact piece;
the first second terminal comprises a second contact portion residing in the second terminal receiving hole, and the second contact portion has a two-half structure and comprises a third contact piece, a fourth contact piece, and a second insertion hole located between the third contact piece and the fourth contact piece.

11 . The backplane connector according to claim 10 , wherein the first contact piece further comprises a first flared portion disposed at an end thereof; the second contact piece further comprises a second flared portion disposed at an end thereof; the first flared portion and the second flared portion jointly form a first bell mouth being in communication with the first insertion hole;
the third contact piece further comprises a third flared portion disposed at an end thereof; the fourth contact piece further comprises a fourth flared portion disposed at an end thereof; the third flared portion and the fourth flared portion jointly form a second bell mouth being in communication with the second insertion hole.

12 . The backplane connector according to claim 9 , wherein the first signal terminal comprises a first mounting foot, and the second signal terminal comprises a second mounting foot;
the housing defines a receiving groove at a bottom end of the base; the backplane connector further comprises a mounting block received in the receiving groove, the mounting block is made of electroplated plastic, and the mounting block comprises an opening through which the first mounting foot and the second mounting foot extend.

13 . A backplane connector, comprising:
a housing comprising a base, a first side wall portion and a second side wall portion; the base, the first side wall portion and the second side wall portion jointly forming a receiving space for at least partially receiving a mating connector; the base defining a positioning groove in communication with the receiving space; a plurality of insulating protrusions protruding into the receiving space; a plurality of terminal modules, each terminal module being assembled to a corresponding insulating protrusion; each terminal module comprising a first signal terminal and a second signal terminal; the first signal terminal comprising a first mounting foot; the second signal terminal comprising a second mounting foot; and a plurality of metal shield surrounding members, each metal shield surrounding member being sleeved on the corresponding insulating protrusion; wherein the metal shield surrounding member comprises a surrounding portion and a mounting portion extending from the surrounding portion along a first direction; the surrounding portion comprises a first side wall, a second side wall, a third side wall and a fourth side wall; the first side wall is disposed opposite to the third side wall; the second side wall is disposed opposite to the fourth side wall; the first side wall, the second side wall, the third side wall and the fourth side wall are enclosed to form a fully-enclosed shielding cavity to at least partially sleeve over the corresponding insulating protrusion; the mounting portion is of a U-shaped con
