Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
An electrical connector comprising: a housing portion having a bottom surface adapted for confronting a printed circuit board (PCB) when the connector is mounted onto the PCB, the housing portion providing a plurality of protrusions on the bottom surface; a plurality of conductive contacts assembled to the housing portion, each contact having a contacting portion for engaging with a terminal of a mating connector, a tail portion extending beyond the bottom surface of the housing for electrically mounting to the PCB and a retention portion connecting the contacting portion with the tail portion, the retention portion of each contact having an inclined section in which a slot is defined so that the contact may be assembled to the housing portion in a bottom-to-top direction with the retention portion straddling on the corresponding protrusion.
Claim 2
Dependent Claim
133 words
An electrical connector comprising: a housing portion having a bottom surface adapted for confronting a printed circuit board (PCB) when the connector is mounted onto the PCB, the housing portion providing a plurality of protrusions on the bottom surface; a plurality of conductive contacts assembled to the housing portion, each contact having a contacting portion for engaging with a terminal of a mating connector, a tail portion extending beyond the bottom surface of the housing for electrically mounting to the PCB and a retention portion connecting the contacting portion with the tail portion, the retention portion of each contact having an inclined section in which a slot is defined so that the contact may be assembled to the housing portion in a bottom-to-top direction with the retention portion straddling on the corresponding protrusion.
Claim 3
Dependent Claim
33 words
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.
Claim 4
Dependent Claim
54 words
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.
Claim 5
Dependent Claim
41 words
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.
Claim 6
Dependent Claim
70 words
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.
Claim 7
Dependent Claim
181 words
An electrical connector comprising: an insulative housing; and a plurality of contacts each of said contacts including: a contact portion offset from a mounting portion via a horizontal connection portion extending along a horizontal direction; said contact portion including a first vertical plane along a vertical direction perpendicular to the horizontal direction, with a spring tang obliquely and upwardly extending therefrom and first lances downwardly extending therefrom; said mounting portion including a second vertical plane along the vertical direction with second lances extending upwardly at a top portion thereof to retainably engage the housing; said first lances commonly defining a first width on first vertical plane alone a lateral direction perpendicular to both said vertical direction and said horizontal direction, said second lances commonly defining a second width on said second vertical plane along said lateral direction, and said horizontal connection portion defining a third width along said lateral direction; wherein the first width is close to the second width but larger than the third width; wherein the spring tang mechanically and electrically engages a blade-like device received in the housing.
