Abstract
Abstract The invention provides for a modularized terminal block and an improved method of manufacturing the modular block. The block permits the connection of a plurality of drop wires or other devices in a reversible manner through the use of a standardized plug in module configuration. The module can be optimized for a given drop wire range which then uniformly connects to the base block through a standardized demateable contact. The mateable connectors each include a collapsible container filled with a sealant material such as gel or grease and an enclosed contact. Upon mating of the contacts, the deformation of the containers maintains the sealant material under compression.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
90 words
An apparatus for forming a reversible and environmentally protected electric contact between electrical contacts comprising: a first elastomeric container containing a first electrical contact and a separate second container containing a second electrical contact directly mateable to the first electrical contact in the first elastomeric container wherein said first elastomeric container is filled with a sealing material and collapsible and radially expandable to maintain the sealing material under compression upon engagement of said first and second electrical contacts, and upon disengagement the sealing material moves back to its prior shape.
Claim 2
Independent Claim
90 words
An apparatus for forming a reversible and environmentally protected electric contact between electrical contacts comprising: a first elastomeric container containing a first electrical contact and a separate second container containing a second electrical contact directly mateable to the first electrical contact in the first elastomeric container wherein said first elastomeric container is filled with a sealing material and collapsible and radially expandable to maintain the sealing material under compression upon engagement of said first and second electrical contacts, and upon disengagement the sealing material moves back to its prior shape.
Claim 3
Dependent Claim
16 words
The apparatus according to claim 1 wherein the second container is filled with a sealing material.
Claim 4
Dependent Claim
14 words
The apparatus according to claim 2 wherein the second container is an elastomeric container.
Claim 5
Dependent Claim
13 words
The apparatus according to claim 3 wherein the sealing material is a grease.
Claim 6
Dependent Claim
13 words
The apparatus according to claim 3 wherein the sealing material is a gel.
Claim 7
Dependent Claim
30 words
The apparatus according to claim 5 wherein the gel has a Voland hardness of from about 525 g to about 5 g with an ultimate elongation of at least 75%.
Claim 8
Dependent Claim
29 words
The apparatus according to claim 6 wherein the gel is selected from the group consisting of poly organo siloxanes, polyurethanes, polyuresas, styrene-butachiene/styrene-isoprene block copolymers, and combinations and mixtures thereof.
Claim 9
Dependent Claim
36 words
The apparatus according to claim 7 wherein the first and second containers are each closed ended with a separating slit member which separates to permit engagement of the first and second electrical contacts when urged together.
Claim 10
Independent Claim
100 words
An apparatus for forming a reversible and environmentally protected electric contact between electrical contacts comprising: a first elastomeric container containing a first electrical contact and a second elastomeric container containing a second electrical contact mateable to the first electrical contact in the first elastomeric container, wherein both said elastomeric containers are filled with a sealing material and collapsible and radially expandable upon engagement of said first and second electrical contacts, and said first and second containers are each closed ended with a separating slit member which separates to permit engagement of the first and second electrical contacts when urged together.
Claim 11
Independent Claim
100 words
An apparatus for forming a reversible and environmentally protected electric contact between electrical contacts comprising: a first elastomeric container containing a first electrical contact and a second elastomeric container containing a second electrical contact mateable to the first electrical contact in the first elastomeric container, wherein both said elastomeric containers are filled with a sealing material and collapsible and radially expandable upon engagement of said first and second electrical contacts, and said first and second containers are each closed ended with a separating slit member which separates to permit engagement of the first and second electrical contacts when urged together.
