Abstract
Abstract An improved sealing means is disclosed for use with high voltage rack and panel connectors. The subject sealing means is received in a cavity of a panel or ferrule member and forms a recess which closely receives a rigid portion of a mating rack or mate connector member. A further portion of the sealing means allows for some flow to compensate for misalignment of the rigid portions of the mating connector members due to inaccuracies resulting from practical molding processes and/or mounting configurations. The configuration of the seal assures that it will remain in the panel when the connector is unmated.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
An improved sealing means for high voltage electrical connectors to provide sealing interfaces between a tubular portion of one rigid mating connector member received in a corresponding cylindrical recess of a mating rigid connector member, said sealing means comprising: a unitary member of resilient material having a substantially cylindrical configuration and adapted to be received within said recess of said mating connector member and accept said tubular portion therein, at least one inwardly directed annular recess formed on the exterior of the sealing means, an inwardly directed annular portion at one end of said member defining an aperture of lesser diameter than the remainder of the cylindrical configuration, said annular portion having substantially the same width as said annular recess, whereby said at least one annular recess allows for deformation and expansion of said member and said reduced diameter portion without lessing the sealing effect achieved by said sealing means.
Claim 2
Dependent Claim
150 words
An improved sealing means for high voltage electrical connectors to provide sealing interfaces between a tubular portion of one rigid mating connector member received in a corresponding cylindrical recess of a mating rigid connector member, said sealing means comprising: a unitary member of resilient material having a substantially cylindrical configuration and adapted to be received within said recess of said mating connector member and accept said tubular portion therein, at least one inwardly directed annular recess formed on the exterior of the sealing means, an inwardly directed annular portion at one end of said member defining an aperture of lesser diameter than the remainder of the cylindrical configuration, said annular portion having substantially the same width as said annular recess, whereby said at least one annular recess allows for deformation and expansion of said member and said reduced diameter portion without lessing the sealing effect achieved by said sealing means.
Claim 3
Dependent Claim
38 words
An improved sealing means according to claim 1 further comprising: an annular flange extending outwardly from the opposite end of said cylindrical configuration from said annular portion, said flange engaging a mating face of said rigid connector member.
Claim 4
Dependent Claim
43 words
An improved sealing means according to claim 2 further comprising: at least one inwardly directed annular restriction in said cylindrical configuration each aligned with a respective annular recess, whereby said recesses provide stress relief for said annular restriction when connector members are mated.
Claim 5
Dependent Claim
44 words
An improved sealing means according to claim 1 wherein said at least one annular recess is closely adjacent to said inwardly directed annular portion whereby compression on the cylindrical configuration of said sealing means will be translated to a constriction of said annular portion.
Claim 6
Dependent Claim
179 words
An improved sealing means for high voltage electrical connectors to provide sealing interfaces between a tubular portion of one rigid mating connector member received in a corresponding recess of a mating rigid connector member, said sealing means comprising: a unitary member of resilient material having a cylindrical configuration including a blind bore closed by an end wall and adapted to be received within said recess of said mating connector member and accept said tubular portion therein, at least one inwardly directed annular restriction in said bore, a like number of annular recesses each aligned on the exterior of the sealing means with a respective annular restriction, a reduced diameter portion at the blind end of said bore, said portion being of lesser diameter than the remainder of the bore, and a corresponding annular recess on the exterior of said sealing means aligned with said portion and being of substantially the same width, whereby said exterior recesses allow for deformation and expansion of said restrictions and said reduced diameter portion without lessing the sealing effect achieved by said sealing means.
Claim 7
Dependent Claim
179 words
An improved sealing means for high voltage electrical connectors to provide sealing interfaces between a tubular portion of one rigid mating connector member received in a corresponding recess of a mating rigid connector member, said sealing means comprising: a unitary member of resilient material having a cylindrical configuration including a blind bore closed by an end wall and adapted to be received within said recess of said mating connector member and accept said tubular portion therein, at least one inwardly directed annular restriction in said bore, a like number of annular recesses each aligned on the exterior of the sealing means with a respective annular restriction, a reduced diameter portion at the blind end of said bore, said portion being of lesser diameter than the remainder of the bore, and a corresponding annular recess on the exterior of said sealing means aligned with said portion and being of substantially the same width, whereby said exterior recesses allow for deformation and expansion of said restrictions and said reduced diameter portion without lessing the sealing effect achieved by said sealing means.
Claim 8
Dependent Claim
26 words
An improved sealing means according to claim 5 wherein: said member has a length substantially the same as the recess of the respective rigid connector member.
Claim 9
Dependent Claim
34 words
An improved sealing means according to claim 5 further comprising: an annular flange extending outwardly from the open end of said cylindrical configuration, said flange engaging a mating face of said rigid connector member.
Claim 10
Dependent Claim
26 words
An improved sealing means according to claim 5 wherein: two annular restrictions are formed in spaced relationship with each other and with said reduced diameter portion.
