Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to electrical connectors, more particularly to electrical connectors with improved contacts to be soldered to a printed circuit board (PCB).
2. Description of Related Art
U.S. Pat. No. 5,769,666 discloses an electrical connector including an insulative housing, a plurality of contacts retained in the housing and a metal shield received in the housing. The contacts include contact portions and bending portions extending downwardly from rear ends of the contact portions. The bending portions are perpendicular to the contact portions and include contractive tail portions for being soldered to a PCB. The metal shield encloses the contact portions for EMI protection. The bending portions directly extend downwardly from the rear ends of the contact portions. The bending portions occupy much area of a rear wall of the housing because a width of the bending portion viewed from a rear-to-front direction is much larger than that viewed from left-to-right direction. As a result, the rear wall of the housing doesn't have reasonable area for mounting components.
Hence, an improved electrical connector is desired to overcome the above problems.
BRIEF SUMMARY OF THE INVENTION
An electrical connector includes a housing member and a plurality of contacts attached to the housing member. The contacts include a plurality of first contacts arranged side by side along a transverse direction, and a plurality of second contacts arranged side by side along the transverse direction as well. Each first contact comprises a first main portion, a first contact portion and a first betiding portion extending from a lateral edge of the first main portion. The first bending portion is substantially perpendicular to the first main portion. Each second contact comprises a second main portion, a second contact portion and a second bending portion extending from a lateral edge of the second main portion. The second bending portion is substantially perpendicular to the second main portion and is parallel to the first bending portion. The first and the second contact portions are located at a same side of the housing member. Each of the second bending portion comprises a first width viewed from a left-to-right direction parallel to the transverse direction, and a second width viewed from a rear-to-front direction perpendicular to the transverse direction in condition that the second width is narrower than the first width. As a result, the narrow second width of the second bending portions can occupy small space of a rear wall of the housing member so that the rear wall of the housing member still has adequate area for mounting other components.
The foregoing has outlined-rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention.
