Abstract

An electrical connector for mounting on a circuit board includes an insulative housing (11) having a pair of side walls (113), a pair of end walls (114) and defining a mating opening (115), and a mounting face and a number of contact receiving slots (112); a plurality of contacts (12) received in the contact receiving slots and each having a soldering portion (125) extending along the mounting face for surface mounting on the circuit board; a pair of shielding plates (13) each having a main portion (132) located outside tail ends of the soldering portion, a bent portion (131) bent from opposite ends of the main potion and attached to the end walls and a grounding pad (135) extending along the mounting face for surface mounting on the circuit board.

Claims

1. An electrical connector assembly for connecting a first and a second circuit boards, comprising:

a plug connector mounted on the first circuit board, comprising;

a first insulative housing having a mounting face, a mating face and a number of contact receiving slots therethrough;

a plurality of first contacts received in the contact receiving slots, each first contact having a soldering portion extending along said mounting face for surface mounting on said first circuit board in a first direction;

a pair of first shielding plates attached to the housing, each shielding plate having a main portion located outside the soldering portion and extending in a second direction perpendicular to said first direction, and a grounding pad extending along said mounting face for surface mounting on said first circuit board;

a receptacle connector mounted on the second circuit board, comprising;

a second insulative housing defining a mounting face, a mating face and a number of contact receiving slots therethrough;

a plurality of second contacts received in the contact receiving slots, each second contact having a soldering portion extending along said mounting face for surface mounting on said second circuit board in said first direction;

a pair of second shielding plates attached to said second housing and contacting with the first shielding plates, and having a main portion disposed outside the soldering portion of the second contact and extending in said second direction, and a grounding pad extending along said mounting face for surface mounting on said second circuit board.

2. The electrical connector assembly as described in claim 1, wherein said first shielding plate has an inclined tab extending inwardly from an upper edge thereof, said second shielding plate has a lead-in tab extending outwardly from an upper edge thereof and cooperating with the inclined tab for easing the insertion of the plug connector into the receptacle connector.

3. The electrical connector assembly as described in claim 1, wherein the second shielding plate further has a number of resilient fingers and dimples both protruding inwardly from an upper edge thereof for contacting with the first shielding plates in both the first direction and the second direction.

4. The electrical connector assembly as described in claim 1, wherein the first housing and the second housing having a number of grooves respectively, the shielding plate both in the plug and the receptacle connector defining a pair of locking tab opposing each other and provided with barbs on opposite edges thereof for interference engagement with the grooves respectively.

5. The electrical connector assembly as described in claim 1, wherein the shielding plate both in the plug and the receptacle connector defines a pair of side portions bent from opposite ends of the main portion and extending in the first direction to the extent that shielding plates either in the plug or the receptacle connector contact with each other respectively.

6. An electrical connector for mounting on a circuit board, comprising:

an insulative housing having a pair of side walls, a pair of end walls connected to said side walls and defining a mating opening for accommodating a mating electrical connector, a mounting face, a mating face and a number of contact receiving slots;

a plurality of contacts received in the contact receiving slots and each having a soldering portion extending along said mounting face for surface mounting on the circuit board;

a pair of shielding plates each having a main portion being located outside tail ends of the soldering portion, a bent portion bent from opposite ends of the main potion and attached to the end walls, and a grounding pad extending horizontally from a lower edge of said main portion along said mounting face for surface mounting on said first circuit board.

7. The electrical connector as described in claim 6, wherein the end walls have a number of grooves, the bent portions each defines a pair of locking tabs on a lower edge thereof for interference engagement with the grooves.

8. The electrical connector as described in claim 6, wherein the shielding plate has a lead-in tab on an upper edge thereof for facilitating engagement with the mating electrical connector.

9. The electrical connector as described in claim 6, wherein the housing further includes a central portion connected to the end walls and dividing the mating opening into two pieces.

10. An electrical connector assembly comprising:

a first connector including a first insulative housing defining a central receiving slot, along a longitudinal direction, with two rows of first contacts located in two first side walls located by two sides of the central receiving slot,

a first metallic shell attached to and enclosing said first housing with a pair of first openings formed between the first housing and the first metallic shell in a transverse direction perpendicular to said longitudinal direction;

a second connector including a second insulative housing defining a central island, along said longitudinal direction, with two rows of second contacts located in two second side walls located by two sides of the central island in said transverse direction, each of said second contacts defining a contact portion located in said central island;

a second metallic shell attached to and enclosing said second housing with a pair of second opening formed between the second housing and the second metallic shell in said transverse direction;

wherein

when the first connector and the second connector mated with each other, the central island is essentially received in the central slot and each of said first openings is roughly occupied by one corresponding said second opening and one corresponding second side wall.

11. The assembly as claimed in claim 10, wherein said first metallic shell is essentially received within the second metallic shell.

12. The assembly as claimed in claim 10, wherein said first metallic shell includes two spaced halves.

13. The assembly as claimed in claim 10, wherein said second metallic shell includes two spaced halves
