Abstract

An electrical connector (100) assembled to a printed circuit board (5) for connecting with a mating connector, includes a longitudinal insulative housing (1) and a plurality of contacts (2, 3) received in the housing. Each of the contacts (2, 3) defines a retaining section (20, 30), a contacting portion (21) extending forwards from the retaining section for contacting with the mating connector and a compressing portion (220, 320) extending rearwards from the retaining section for connecting to the printed circuit board. The compressing portions are arranged in two rows, and the compressing portions nip and elastic compress against the printed circuit board instead of being soldered thereto to connect the electrical connector to the printed circuit board steadily.

Claims

1. An electrical connector assembled to a printed circuit board for connecting with a mating connector, comprising:

a longitudinal insulative housing; and

a plurality of contacts received in the housing, each of the contacts defining a retaining section, a contacting portion extending forwards from the retaining section for contacting with the mating connector and a compressing portion extending rearwards from the retaining section for connecting to the printed circuit board;

wherein the compressing portions are arranged in two rows, and the compressing portions nip and elastic compress against the printed circuit board instead of being soldered thereto to connect the electrical connector to the printed circuit board steadily.

2. The electrical connector as described in claim 1, wherein the two rows of the compressing portions bend towards each other and offset in a mating direction.

3. The electrical connector as described in claim 1, wherein the housing defines a plurality of receiving grooves therein, and each free end of the compressing portions is received in a corresponding receiving groove.

4. The electrical connector as described in claim 3, wherein each of the receiving grooves defines a blocking portion thereof, the free end of each compressing portion abut against the blocking portion, after the connector assembled to the printed circuit board, the compressing portion is compressed towards an inner surface of the receiving groove to make the free end contact the inner surface.

5. The electrical connector as described in claim 1, wherein the housing defines guiding portions extending upwards, the printed circuit board defines corresponding guiding holes to cooperate with the guiding portions.

6. The electrical connector as described in claim 1, wherein the electrical connector defines a first shell covering on the housing, the first shell defines a pair of locking arms for locking with the printed circuit board.

7. An electrical connector assembly for connecting with a mating connector, comprising:

a printed circuit board; and

an electrical connector assembled to the printed circuit board, comprising;

a insulative housing;

a shell covering on the housing; and

a plurality of contacts received in the housing, each of the contacts defining a retaining section, a contacting portion extending forwards from the retaining section for contacting with the mating connector and a compressing portion extending rearwards from the retaining section for connecting to the printed circuit board;

wherein the compressing portions are arranged in two rows, the electrical connector is set slantways to make the two rows of the compressing portions sandwich the printed circuit board, and after the electrical connector is rotated to parallel to the printed circuit board, the electrical connector is connected to the printed circuit board by the compressing portions nipping and elastic compressing against the printed circuit board without soldering.

8. The electrical connector assembly as described in claim 7, wherein the two rows of the compressing portions are located in different positions along a mating direction.

9. The electrical connector assembly as described in claim 7, wherein the shell defines a pair of locking arms for locking with the printed circuit board.

10. An electrical connector assembly comprising:

an insulative housing defining opposite front and rear regions;

two rows of contacts disposed in the housing and defining opposite mating and mounted sections respectively at the front and rear regions;

a printed circuit board located behind the rear region and defining opposite first and second surfaces thereof;

a first shell assembled upon the housing and located upon the first surface;

a second shell assembled upon the housing and located upon the second surface;

wherein

rear portions of said first shell and said second shell are separated from each other by said printed circuit board while front portions of the first shell and the second shell are joined together.

11. The electrical connector assembly as claimed in claim 10, wherein the printed circuit board defines a pair of slots extending through said first and second surfaces, and the rear region of the housing defines two opposite walls extending therethrough.

12. The electrical connector assembly as claimed in claim 10, wherein said second shell defines a pair of latches extending therethrough the corresponding slots.
