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 respectively 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: 8
Claim 1
Independent Claim
168 words
An arrangement for correctly assembling an electrical connector assembly, comprising: a male connector including a first housing defining at least two columns and least two rows of sleeve members extending forward from the first housing; a female connector including a second housing having an outer wall defining at least two rows and two columns of cavities therein; wherein two sleeve members at two opposite ends of the first housing each have a first configured structure so that the two sleeve members respectively having the first configured structures have a configuration different from that of other sleeve members; and two portions of the outer wall of the second housing adjacent to two opposite ends of the second housing each have a second configured structure complementary the first configured structure; 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
168 words
An arrangement for correctly assembling an electrical connector assembly, comprising: a male connector including a first housing defining at least two columns and least two rows of sleeve members extending forward from the first housing; a female connector including a second housing having an outer wall defining at least two rows and two columns of cavities therein; wherein two sleeve members at two opposite ends of the first housing each have a first configured structure so that the two sleeve members respectively having the first configured structures have a configuration different from that of other sleeve members; and two portions of the outer wall of the second housing adjacent to two opposite ends of the second housing each have a second configured structure complementary the first configured structure; 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
245 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 sleeve 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 first configured structures; formed at two of the sleeves near the two lateral walls and the top wall of the housing so that the two sleeves respectively having the first configured structures have a configuration different from that of other sleeves; 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 second configured structures complementary to the first configured structures being formed at 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 4
Dependent Claim
245 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 sleeve 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 first configured structures; formed at two of the sleeves near the two lateral walls and the top wall of the housing so that the two sleeves respectively having the first configured structures have a configuration different from that of other sleeves; 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 second configured structures complementary to the first configured structures being formed at 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.
