Abstract

An electrical connector is mounted to a printed circuit board which defines a plurality of fastening holes. The electrical connector includes an insulating housing, a plurality of terminals disposed in the insulating housing, and a shielding shell enclosing the insulating housing. Two outer sides of the insulating housing respectively extend outward and then extend forward to form a fastening arm. A narrow slot is formed between the fastening arm and a corresponding side of the insulating housing. The shielding shell has two side plates each of which extends outward and then inclines upward to form a first soldering arm inserted into the fastening hole. A receiving space is formed between each side plate and the corresponding first soldering arm. The fastening arms are snapped into the receiving spaces and rears of the side plates are clipped in the corresponding narrow slots.

Claims

1. An electrical connector for being mounted to a printed circuit board, the printed circuit board having a containing gap opened at one side thereof and defining a plurality of fastening holes arranged around the containing gap, the electrical connector being received in the containing gap, comprising:

an insulating housing, the insulating housing having a base portion with two outer sides of rear ends thereof respectively extending outward and then extending forward beyond the base portion to form a fastening arm, a narrow slot being formed between the fastening arm and a corresponding side of the insulating housing;

a plurality of terminals disposed in the insulating housing; and

a shielding shell enclosing the insulating housing, and having two opposite side plates, a bottom portion of each side plate extending outward and then inclining upward to form a first soldering arm inserted into the corresponding fastening hole and then soldered together with the printed circuit board, a receiving space being formed between each of the side plates and the first soldering arm adjacent to the corresponding side plate, the fastening arms being snapped into the receiving spaces and abutting against the respective side plates and insides of the first soldering arms with rears of the side plates being clipped in the corresponding narrow slots.

2. The electrical connector as claimed in claim 1, wherein each of the first soldering arms includes a first soldering base extending horizontally, a first slanting portion inclined upward from a free end of the soldering base and an first inserting portion extending upward from a free end of the first slanting portion, the fastening arms abut against insides of the first soldering bases and the first slanting portions, and the first inserting portion of the first soldering arms are inserted into the fastening holes.

3. The electrical connector as claimed in claim 1, wherein two rear corners of the base portion respectively extend outward and then rearward to form a connecting block, an outer side of each of the connecting blocks extends outward, and then extends forward to form the fastening arm.

4. The electrical connector as claimed in claim 3, wherein the shielding shell has a base plate, a rear end of the base plate is extended rearward to form a rear plate, two side edges of the rear plate extend outward and then are bent upward to form two second soldering arms, the connecting blocks are located at two sides of the rear plate, the second soldering arms are inserted and soldered to the corresponding fastening holes of the printed circuit board and restrict rear ends of the fastening arms.

5. The electrical connector as claimed in claim 1, wherein two opposite fixing openings are defined in the corresponding side plates, respectively, bottom ends of the two fixing openings extend outward and then are bent upward to form the first soldering arms.

6. The electrical connector as claimed in claim 1, wherein the shielding shell is of a hollow shape with an inserting space formed for accommodating the base portion of the insulating housing and a tongue portion extended from.
