Abstract
Abstract This invention relates to a device and method for sealing openings such as found on the rear faces of electrical connectors from which a number of electrical leads emanate. More particularly, the invention relates to a layer of sealable material attached to a rigid member to form a disk which can be pressed into a recess in the rear face of a connector, the pressure causing the material to flow into passageways and openings and sealing the electrical leads therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
248 words
A multi-contact electrical connector housing, said housing being adapted to receive electrical contact terminals which are crimped onto wires, said housing comprising: a molded block of hard plastic insulating material, said block having a mating face and a rearward face, a plurality of contact-receiving cavities extending through said block from said rearward face to said mating face, an axial flange extending around the periphery of said rearward face, said flange defining an enclosure extending continuously around said cavities, a sealing member of flowable material in said enclosure against said rearward face, said sealing member having a thickness which is less than the height of said flange whereby said sealing member is received from the edge of said flange, said sealing member having first openings therein in alignment with said cavities, and a pressure plate member in said enclosure, said pressure plate member fitting snugly within said enclosure and having a radially extending flange, said flange being spaced from said edge, said pressure plate member being of a hard plastic material and having second openings therein which are in alignment with said first openings and said cavities whereby, upon inserting said terminals through said openings and into said cavities and thereafter pressing said pressure plate member into said enclosure until said radially extending flange is seated against said edge of said axial flange, said sealing member is compressed and caused to flow into said second openings and into said cavities, and circumferential seals are thereby formed around said terminals.
Claim 2
Dependent Claim
248 words
A multi-contact electrical connector housing, said housing being adapted to receive electrical contact terminals which are crimped onto wires, said housing comprising: a molded block of hard plastic insulating material, said block having a mating face and a rearward face, a plurality of contact-receiving cavities extending through said block from said rearward face to said mating face, an axial flange extending around the periphery of said rearward face, said flange defining an enclosure extending continuously around said cavities, a sealing member of flowable material in said enclosure against said rearward face, said sealing member having a thickness which is less than the height of said flange whereby said sealing member is received from the edge of said flange, said sealing member having first openings therein in alignment with said cavities, and a pressure plate member in said enclosure, said pressure plate member fitting snugly within said enclosure and having a radially extending flange, said flange being spaced from said edge, said pressure plate member being of a hard plastic material and having second openings therein which are in alignment with said first openings and said cavities whereby, upon inserting said terminals through said openings and into said cavities and thereafter pressing said pressure plate member into said enclosure until said radially extending flange is seated against said edge of said axial flange, said sealing member is compressed and caused to flow into said second openings and into said cavities, and circumferential seals are thereby formed around said terminals.
Claim 3
Dependent Claim
14 words
A connector housing as set forth in claim 1, said connector housing being cylindrical.
Claim 4
Dependent Claim
189 words
A sealed multi-contact electrical connector, said connector comprising: a generally cylindrical insulating housing, said housing being of a hard plastic material and having a mating face and a rearward face, a plurality of cavities extending through said housing from said rearward face to said mating face, an axially extending circular flange extending from said rearward face, said flange defining an enclosure surrounding said cavities. a pressure plate member in said enclosure, said pressure plate member comprising a disc snugly fitted within said enclosure, said disc being spaced from said rearward face and having a radiallY extending flange, said radially extending flange being against the edge of said circular flange, said pressure plate member having a plurality of openings therein in alignment with said cavities, an electrical contact terminal having a wire secured thereto in each of said cavities, said wires extending through said openings, and a compressed matrix of sealing material between said rearward face and said pressure plate member, said sealing material being extruded through said openings and onto external surface portions of said pressure plate member, said sealing material forming a seal around said wires and terminals.
Claim 5
Dependent Claim
189 words
A sealed multi-contact electrical connector, said connector comprising: a generally cylindrical insulating housing, said housing being of a hard plastic material and having a mating face and a rearward face, a plurality of cavities extending through said housing from said rearward face to said mating face, an axially extending circular flange extending from said rearward face, said flange defining an enclosure surrounding said cavities. a pressure plate member in said enclosure, said pressure plate member comprising a disc snugly fitted within said enclosure, said disc being spaced from said rearward face and having a radiallY extending flange, said radially extending flange being against the edge of said circular flange, said pressure plate member having a plurality of openings therein in alignment with said cavities, an electrical contact terminal having a wire secured thereto in each of said cavities, said wires extending through said openings, and a compressed matrix of sealing material between said rearward face and said pressure plate member, said sealing material being extruded through said openings and onto external surface portions of said pressure plate member, said sealing material forming a seal around said wires and terminals.
