Abstract

A male connector (

10) includes first and second individual housing portions (

28, 30) engaging with each other, a number of printed substrates (

16) held by the first housing portion and a number of signal contacts (

18) and a number of grounding terminals (

20) held by the second housing portion with the signal contacts confronting the grounding terminals. Each printed substrate has a first edge (

108) and a second edge (

110) orthogonal with the first edge. The first edges of the printed substrates are hidden behind corresponding lead-in bars (

44) of the first housing portion and the second edges of the printed substrates are sandwiched between and removeably held by the signal contacts and the grounding terminals. The second edges of the printed substrates are pushed toward the signal contacts by the grounding terminals because the grounding terminals are somewhat stronger than the signal contacts. A female connector (

12) mateable with the male connector includes a dielectric member (

22) and a number of signal contacts (

24) and a number of grounding terminals (

26) retained in the dielectric member in face-to-face relationship. The signal contacts straddle on a bottom surface (

128) of the dielectric member. Each signal contact (

24) has an inclined retention portion (

132) defining a slot (

136) engageably receiving a protrusion (

130) of the dielectric member on the bottom face thereof. The male and the female connectors have a guiding means for guiding the connectors to correctly mate with each other.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is an assembled perspective view of a male connector and a female connector respectively mounted onto a first and a second printed circuit boards (PCBs);

FIG. 2 is a front-top perspective view of the male connector mounted on the first PCB;

FIG. 3 is an exploded perspective view of first and second housing portions of the male connector;

FIGS. 4A and 4B are enlarged sections of FIG. 3;

FIG. 5 is a rear-top perspective view of the first housing portion in FIG. 3;

FIGS. 6A-6C are enlarged perspective views of signal contacts of the male connector in three embodiments;

FIG. 7 is an enlarged perspective view of a grounding terminal of the male connector;

FIGS. 8A-8B are opposite perspective views of a substrate of the male connector;

FIG. 9 is a cross-sectional view of a section of the second housing portion and the substrates attached to the second housing portion;

FIG. 10 is a top-front perspective view of the female connector mounted on the second PCB;

FIGS. 11A-11B are enlarged top and bottom perspective views of a section of the female connector in FIG. 10;

FIG. 12 is an enlarged cross-sectional view of a section of the assembly of the male and the female connectors;

FIGS. 13A-13B are perspective views of the assembly of the male and female connectors taken from different perspectives, wherein the housings are removed to clearly show the engagement of the substrates with the signal contacts and the grounding terminals; and

FIG. 14 is a top planar view of a PCB of an alternative embodiment of this invention.

Claims

1. An electrical connector comprising:

2. The electrical connector as claimed in claim 1, wherein the retention portion of each contact has a pair of ribs sandwiching the corresponding protrusion on the bottom surface of the housing portion.

3. The electrical connector as claimed in claim 1, wherein the housing portion provides two stand-offs on the bottom surface of the housing portion, the stand-offs depending downwards from the bottom surface of the housing portion a distance which is larger than that the protrusions depend from the bottom surface of the housing portion.

4. The electrical connector as claimed in claim 1, wherein the tail portion of each contact offsets a predetermined distance from the contacting portion of the same contact in a predetermined direction due to the inclined section of the retention portion.

5. The electrical connector as claimed in claim 4 further comprising at least one grounding terminal having a contacting arm extending into the housing portion and a tail portion extending beyond the bottom surface of the housing portion, the tail portion of the grounding terminal being aligned with the tail portions of the contacts while the contacting arm of the grounding terminal being spaced from the contacting portions of the contacts.

6. An electrical connector comprising:
