Abstract
Abstract An electrical connector having an insulating housing has a rear face with a plurality of electrical terminals extending therethrough. A sealant material in the form of a hotmelt material is placed over the ends of the terminals and the connector, including the sealing material, is thereafter heated to melt the material. The sealing material flows around the terminals and partially into the apertures of the housing to provide for a sealed atmosphere on the interior of the connector housing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A method of making an electrical connector of the type comprising an insulating housing and a plurality of electrical terminals, the insulating housing having a rear face having a plurality of apertures extending therethrough for the receipt of the terminals, with end portions of the terminals extending beyond the rear face, the method comprising sealing the rear face of the connector by the steps of: providing a sealant material having a melting temperature which is less than that of the insulative housing; placing the sealant material adjacent to the rear face of the connector with the end portions of the terminals extending through the sealant material; subsequently heating the sealant material to the point where the sealant material melts and flows around the terminals; and cooling the sealant material to solidify the sealant material.
Claim 2
Independent Claim
134 words
A method of making an electrical connector of the type comprising an insulating housing and a plurality of electrical terminals, the insulating housing having a rear face having a plurality of apertures extending therethrough for the receipt of the terminals, with end portions of the terminals extending beyond the rear face, the method comprising sealing the rear face of the connector by the steps of: providing a sealant material having a melting temperature which is less than that of the insulative housing; placing the sealant material adjacent to the rear face of the connector with the end portions of the terminals extending through the sealant material; subsequently heating the sealant material to the point where the sealant material melts and flows around the terminals; and cooling the sealant material to solidify the sealant material.
Claim 3
Dependent Claim
15 words
The method of claim 1 wherein the heating step is undertaken in a convection oven.
Claim 4
Dependent Claim
22 words
The method of claim 2 further comprising the step of rotating the connectors within the oven to uniformly heat the sealant material.
Claim 5
Independent Claim
31 words
The method of either of claims 1 or 2 wherein the heating step includes the heat transfer equivalent of an oven temperature of 180° C. for a duration of one minute.
Claim 6
Dependent Claim
31 words
The method of claim 1 wherein, prior to placing sealant material adjacent to the rear face, the sealant material is formed to include apertures extending therethrough to match the terminal pattern.
Claim 7
Dependent Claim
14 words
The method of claim 1 wherein the sealant material is a hot melt material.
