Abstract
Abstract An electrical connector assembly includes a male connector (10, 10') and a female connector (50, 50') wherein the male connector (10, 10') includes an insulative first housing (12, 12') with at least one row of sleeve members (14, 14') extending forward for accommodating a corresponding number of receptacle contacts therein and the female connector (50, 50') includes an insulative second housing (52, 52') defining a same number of cavities (54, 54') therein for respectively receiving a corresponding number of plug contacts therein and further being adapted to respectively receive the corresponding sleeve members (14, 14') of the male connector (10) so that each plug contact can be engaged with the corresponding receptacle contact which is accommodated within the sleeve member (14, 14') which shares the same cavity (54, 54') with the plug contact. A pair of keys (18, 18') are respective disposed on two sleeve members (14, 14') at two opposite ends, and a pair of keyways (58, 58') are respectively formed, adjacent to two cavities (54, 54') at two opposite ends, in the housing (52, 52') of the female connector (50, 50'), thus assuring only the male connector (10, 10') and the female connector (50, 50') having the same number of the mating ports, i.e., the sleeve members (14, 14')/the cavities (54, 54'), can be mated with each other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
An arrangement for correctly assembling an electrical connector assembly, comprising: a male connector including a first housing defining at least two columns of sleeve members extending forward from the first housing; a female connector including a second housing defining at least one row and two columns of cavities therein; a pair of keys respectively formed on two sleeve members at two opposite ends of the first housing; and a pair of keyways respectively formed in walls adjacent two opposite ends of the second housing; whereby only when an amount of the sleeve members of the male connector is equal to that of the cavities of the female connector, said male and female connectors can be mated with each other to form the connector assembly.
Claim 2
Dependent Claim
124 words
An arrangement for correctly assembling an electrical connector assembly, comprising: a male connector including a first housing defining at least two columns of sleeve members extending forward from the first housing; a female connector including a second housing defining at least one row and two columns of cavities therein; a pair of keys respectively formed on two sleeve members at two opposite ends of the first housing; and a pair of keyways respectively formed in walls adjacent two opposite ends of the second housing; whereby only when an amount of the sleeve members of the male connector is equal to that of the cavities of the female connector, said male and female connectors can be mated with each other to form the connector assembly.
Claim 3
Dependent Claim
25 words
The arrangement as defined in claim 1, wherein the keys and the corresponding keyways comply with each other in the same direction for orientation consideration.
Claim 4
Dependent Claim
23 words
The arrangement as defined in claim 1, wherein an amount of rows of the sleeve members is equal to that of the cavities.
Claim 5
Dependent Claim
27 words
The arrangement as defined in claim 1, wherein said pair of keys extend in a direction the same as that of the sleeves of the first housing.
Claim 6
Dependent Claim
84 words
A mating system for an electrical connector assembly, comprising: a first connector defining at least two columns of first mating ports; a second connector defining at least two columns of second mating ports; at least two keys disposed adjacent two of said first mating ports; at least two keyways disposed adjacent two of said second mating ports; wherein said two keys comply with said two keyways only when an amount of said first mating ports is equal to that of said second mating ports.
Claim 7
Dependent Claim
84 words
A mating system for an electrical connector assembly, comprising: a first connector defining at least two columns of first mating ports; a second connector defining at least two columns of second mating ports; at least two keys disposed adjacent two of said first mating ports; at least two keyways disposed adjacent two of said second mating ports; wherein said two keys comply with said two keyways only when an amount of said first mating ports is equal to that of said second mating ports.
Claim 8
Dependent Claim
214 words
An electrical connector assembly, including: a male connector, comprising: a first housing having a front face for engaging with a mating female connector, two lateral walls extending rearwardly from two lateral sides of the front face and a top wall in rear of the front face and between the two lateral walls; a number of sleeves members arranged in at least two parallel rows extending forward from the front face of the first housing, each sleeve member being used for receiving a contact therein; at least two keys on faces of two of the sleeves near the two lateral walls and the top wall of the housing; and a female connector, comprising: a second housing having two lateral walls and a top wall between the two lateral walls; a number of cavities arranged in at least two parallel rows in the second housing, each cavity being used for receiving a contact therein; at least two keyways in two of the cavities near the two lateral walls and the top wall of the second housing; whereby only when an amount of the sleeve members of the male connector is equal to that of the cavities of the female connector, said male and female connectors can be mated with each other to form the connector assembly.
Claim 9
Dependent Claim
214 words
An electrical connector assembly, including: a male connector, comprising: a first housing having a front face for engaging with a mating female connector, two lateral walls extending rearwardly from two lateral sides of the front face and a top wall in rear of the front face and between the two lateral walls; a number of sleeves members arranged in at least two parallel rows extending forward from the front face of the first housing, each sleeve member being used for receiving a contact therein; at least two keys on faces of two of the sleeves near the two lateral walls and the top wall of the housing; and a female connector, comprising: a second housing having two lateral walls and a top wall between the two lateral walls; a number of cavities arranged in at least two parallel rows in the second housing, each cavity being used for receiving a contact therein; at least two keyways in two of the cavities near the two lateral walls and the top wall of the second housing; whereby only when an amount of the sleeve members of the male connector is equal to that of the cavities of the female connector, said male and female connectors can be mated with each other to form the connector assembly.
