Abstract
Abstract A multipolar connector includes a female connector having a female housing for accommodating and supporting a plurality of first connecting terminals, a male connector having a male housing for accommodating and supporting a plurality of second connecting terminals each connectable to a corresponding one of the first connecting terminals. A seal member is positioned between opposing end faces of the female and male connectors when the female and male connectors are coupled with each other. Overlapping portions are formed between individual connecting terminals on the end faces of the female and male housings opposing through the seal member and overlapping portions are formed on the seal member for intimate contact engagement with the overlapping portions on said female and male housings.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
A multipolar connector including a female connector having a female housing for accommodating and supporting a plurality of first connecting terminals, a male connector having a male housing for accommodating and supporting a plurality of second connecting terminals each connectable to a corresponding one of said first connecting terminals, and a seal member positioned between opposing end faces of said female and male connectors when said female and male connectors are coupled to each other, characterized in that said multipolar connector comprises: an overlapping portion formed between and around individual connecting terminals on the end face of each of said female and male housings opposing each other through said seal member; and an overlapping portion formed on said seal member and intimately engageable with said overlapping portions on said female and male housings in an overlapped state when said female connector is coupled to said male connector.
Claim 2
Dependent Claim
147 words
A multipolar connector including a female connector having a female housing for accommodating and supporting a plurality of first connecting terminals, a male connector having a male housing for accommodating and supporting a plurality of second connecting terminals each connectable to a corresponding one of said first connecting terminals, and a seal member positioned between opposing end faces of said female and male connectors when said female and male connectors are coupled to each other, characterized in that said multipolar connector comprises: an overlapping portion formed between and around individual connecting terminals on the end face of each of said female and male housings opposing each other through said seal member; and an overlapping portion formed on said seal member and intimately engageable with said overlapping portions on said female and male housings in an overlapped state when said female connector is coupled to said male connector.
Claim 3
Dependent Claim
64 words
A multipolar connector according to claim 1, wherein said overlapping portions on said female and male housings are protuberances and apertures and said overlapping portions on said seal member are apertures and protuberances wherein corresponding protuberances and apertures of said female and male housings intimately contact corresponding apertures and protuberances of said seal member when said female connector is coupled to said male connector.
Claim 4
Dependent Claim
22 words
A multipolar connector according to claim 2, wherein said protuberances include an annular sealing ridge disposed around an outer peripheral surface thereof.
Claim 5
Dependent Claim
22 words
A multipolar connector according to claim 2, wherein said protuberances include an annular sealing ridge disposed around an inner peripheral surface thereof.
Claim 6
Dependent Claim
147 words
A waterproof electrical connector including a socket housing accommodating a plurality of contacts, a plurality of pin connectors adapted to be connected to corresponding contacts, a pin connector housing accommodating a plurality of pin terminals formed with recesses fittingly engageable with said socket housing, and a seal member adapted to fit in a gap formed between peripheral surfaces of said socket housing and said connector housing when said socket and said pin connector are coupled with each other, sealing off said pin terminals and said contacts as a whole against intrusion of water, characterized in that: said socket housing includes cylindrical contact receptacle walls for circumventing the respective contacts installed thereon; and said seal member is positioned around said contact receptacle walls thereby sealing off the adjacent contacts and pin terminals independently of each other when said pin connector and said socket are coupled with each other.
Claim 7
Dependent Claim
147 words
A waterproof electrical connector including a socket housing accommodating a plurality of contacts, a plurality of pin connectors adapted to be connected to corresponding contacts, a pin connector housing accommodating a plurality of pin terminals formed with recesses fittingly engageable with said socket housing, and a seal member adapted to fit in a gap formed between peripheral surfaces of said socket housing and said connector housing when said socket and said pin connector are coupled with each other, sealing off said pin terminals and said contacts as a whole against intrusion of water, characterized in that: said socket housing includes cylindrical contact receptacle walls for circumventing the respective contacts installed thereon; and said seal member is positioned around said contact receptacle walls thereby sealing off the adjacent contacts and pin terminals independently of each other when said pin connector and said socket are coupled with each other.
Claim 8
Dependent Claim
116 words
A waterproof electrical connector as defined in claim 5, wherein said seal member comprises a unitary structure containing a plurality of seal portions to be fitted on said cylindrical socket receptacle walls for sealing the connected contacts and pin terminals independently of each other when said pin connector and said socket are coupled with each other, said unitary structure having the fore end and peripheral surface intimately fit in bottom and inner peripheral surfaces of said fitting recess of said connector housing, said seal member being provided with ridges and apertures on the surfaces in contact with said cylindrical contact receptacle walls, and said ridges being held in intimate contact with said cylindrical contact receptacle walls.
Claim 9
Dependent Claim
17 words
A waterproof electrical connector according to claim 5, wherein said contacts of said socket are press-on terminals.
Claim 10
Dependent Claim
17 words
A waterproof electrical connector according to claim 6, wherein said contacts of said socket are press-on terminals.
Claim 11
Dependent Claim
147 words
A multipolar connector including a female connector having a female housing for accommodating and supporting a plurality of first connecting terminals, a male connector having a male housing for accommodating and supporting a plurality of second connecting terminals each connectable to a corresponding one of said first connecting terminals, and a seal member positioned between opposing end faces of said female and male connectors when said female and male connectors are coupled to each other comprising: an overlapping portion formed between and around individual connecting terminals on the end face of each of said female and male housings opposing each other through said seal member; and said seal being positioned adjacent to and extending along said overlapping portions on said female and male housings for sealing off the adjacent individual connecting terminals independently of each other when said female and male housings are coupled to each other.
Claim 12
Dependent Claim
147 words
A multipolar connector including a female connector having a female housing for accommodating and supporting a plurality of first connecting terminals, a male connector having a male housing for accommodating and supporting a plurality of second connecting terminals each connectable to a corresponding one of said first connecting terminals, and a seal member positioned between opposing end faces of said female and male connectors when said female and male connectors are coupled to each other comprising: an overlapping portion formed between and around individual connecting terminals on the end face of each of said female and male housings opposing each other through said seal member; and said seal being positioned adjacent to and extending along said overlapping portions on said female and male housings for sealing off the adjacent individual connecting terminals independently of each other when said female and male housings are coupled to each other.
