Abstract
Abstract A splice case for encapsulating a substrate includes first and second containers each of which contain a gel having a cone penetration between 100 and 350 (10 -1 mm) and an ultimate elongation of at least 200%, the gel in each container having an exposed surface, one exposed surface having a cross-sectional area larger than the cross-sectional area of the other exposed surface, the first and second containers being adapted for telescopic engagement. The substrate is located on one of the exposed surfaces of the gel, and the containers are arranged such that the exposed surfaces of the gel of the first and second containers contact each other and are maintained in compressive contact by a spring capable of maintaining a sufficiently large spring force to repel environmental contamination (for example, water) regardless of the engagement of the containers in response to the biasing force of the spring, substrate volume, or other external factors such as expansions and contractions caused by, for example, temperature changes. Additionally, the splice case may contain means for enhancing the encapsulation of the substrate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
123 words
A case for encapsulating an information transmitting conductor, comprising: at least one gel having a cone penetration value from approximately 100 to 350 (10 -1 m) and an ultimate elongation of at least approximately 200%; first and second open containers for containing the gel, a exposed first surface of the gel in the first container having a cross-sectional area which confronts and contacts a second cross-sectional area of an exposed second surface of the gel in the second container; means for continuously maintaining at least a minimum pressure between the first and second gel surfaces regardless of any reduction in a volume occupied by the gel created by temperature variations, the information transmitting conductor being disposed between the first and second gel surfaces.
Claim 2
Dependent Claim
123 words
A case for encapsulating an information transmitting conductor, comprising: at least one gel having a cone penetration value from approximately 100 to 350 (10 -1 m) and an ultimate elongation of at least approximately 200%; first and second open containers for containing the gel, a exposed first surface of the gel in the first container having a cross-sectional area which confronts and contacts a second cross-sectional area of an exposed second surface of the gel in the second container; means for continuously maintaining at least a minimum pressure between the first and second gel surfaces regardless of any reduction in a volume occupied by the gel created by temperature variations, the information transmitting conductor being disposed between the first and second gel surfaces.
Claim 3
Dependent Claim
29 words
The case as claimed in claim 1, the case encapsulating a plurality of conductors and further comprising means in one of the containers for separating and organizing the conductors.
Claim 4
Dependent Claim
21 words
The case as claimed in claim 2, further comprising a terminal block in one of the containers for terminating the conductors.
Claim 5
Dependent Claim
24 words
The case as claimed in claim 1, a cohesive strength of the gel exceeding an adhesive strength between the first and second gel surfaces.
Claim 6
Dependent Claim
35 words
The case as claimed in claim 1, the means being releasable so as to allow the first and second gel surfaces to be separated from one another so as to allow removal of the conductor.
Claim 7
Dependent Claim
20 words
The case as claimed in claim 4, the gel having a cone penetration between 270 and 300 10 -1 mm).
Claim 8
Dependent Claim
26 words

Claim 9
Dependent Claim
12 words
The case as claimed in claim 1, the means including a spring.
Claim 10
Dependent Claim
29 words

Claim 11
Dependent Claim
49 words
The case of claim 1, further including a split bolt and mating nut capable of being interconnected via threads, the split bolt including a pin extension which fits in a hole of one of the containers for maintaining the bolt in position relative to said one of the containers.
Claim 12
Dependent Claim
21 words
The case of claim 3, further including a conductor organizer attached to said one of the containers via a flexible hinge.
Claim 13
Dependent Claim
32 words
The case as claimed in claim 1, the maintaining means continuously maintaining at least the minimum pressure when either one of the containers deforms and enlarges in response to the minimum pressure.
Claim 14
Dependent Claim
40 words
The case as claimed in claim 12, the maintaining means continuously maintaining at least the minimum pressure regardless of any changes in volume of interior sections of the containers and of any changes in the volume occupied by the gel.
