Abstract
Abstract The invention comprises a cable splice enclosure comprises a base having an outlet capable of receiving a cable a hollow cover which can be fixed to the base to close at least partially the enclosure such that the adjacent external surfaces of the base and the cover lay substantially flush, in which the base and cover, and a ring means which prevents the separation of the base and cover, said means lying substantially flush with or below said adjacent external surfaces and said ring means having a broader base adjacent the enclosure than the side facing away from the enclosure. The invention also includes a device for joning two items in interdigitated fashion wherein a ring having a cross-sectional base greater adjacent the two items to be joined than away therefrom lies in a recess between the two parts to be joined.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A cable splice enclosure comprising: a base having an outlet capable of receiving a cable; and a hollow cover which can be fixed to the base in an interdigitated fashion to close at least partially the enclosure so that the adjacent external surfaces of the base and cover lay substantially mutually flush, in which the base and cover have means which can prevent their separation, said means lying substantially flush with or below said external surfaces, and said means having a cross-sectional shape which exerts a force substantially along the neutral axis of the mating of the base and the cover.
Claim 2
Dependent Claim
101 words
A cable splice enclosure comprising: a base having an outlet capable of receiving a cable; and a hollow cover which can be fixed to the base in an interdigitated fashion to close at least partially the enclosure so that the adjacent external surfaces of the base and cover lay substantially mutually flush, in which the base and cover have means which can prevent their separation, said means lying substantially flush with or below said external surfaces, and said means having a cross-sectional shape which exerts a force substantially along the neutral axis of the mating of the base and the cover.
Claim 3
Dependent Claim
55 words
The enclosure according to claim 1 wherein the means for preventing the separation is a retaining ring within a groove in the interdigitated portions in the hollow cover and the base and the retaining ring has a cross-section along its base adjacent to the enclosure which is broader than the portion away from the enclosure.
Claim 4
Dependent Claim
30 words
The enclosure according to claim 2 wherein the retaining ring has a cross-section selected from the group consisting of trapezoidal, semi-circular, triangular, cusped triangular, cusped trapezoidal, and inverted "T" shape.
Claim 5
Dependent Claim
17 words
The apparatus according to claim 3 wherein the cross-section of the retaining ring has a trapezoidal shape.
Claim 6
Dependent Claim
140 words
A joining device which comprises a first hollow part having a generally cylindrical portion comprising first axially-extending projections, the projections having generally circumferentially-extending first recesses in an external surface thereof; a second hollow part having a generally cylindrical portion comprising second axially-extending projections, the projections having generally circumferentially-extending second recesses in external surfaces thereof, the first hollow part being capable of being fixed to the second hollow part with the first and second projections mated in an interdigitated fashion, the first and second recesses lying on a common circle; and a ring that can be positioned in the first and second recesses to prevent axially separation of the first and second parts, the ring having a cross-section at its base adjacent to the first and second parts which is broader than its cross-section away from the first and second parts.
Claim 7
Dependent Claim
140 words
A joining device which comprises a first hollow part having a generally cylindrical portion comprising first axially-extending projections, the projections having generally circumferentially-extending first recesses in an external surface thereof; a second hollow part having a generally cylindrical portion comprising second axially-extending projections, the projections having generally circumferentially-extending second recesses in external surfaces thereof, the first hollow part being capable of being fixed to the second hollow part with the first and second projections mated in an interdigitated fashion, the first and second recesses lying on a common circle; and a ring that can be positioned in the first and second recesses to prevent axially separation of the first and second parts, the ring having a cross-section at its base adjacent to the first and second parts which is broader than its cross-section away from the first and second parts.
Claim 8
Dependent Claim
30 words
The joining device according to claim 5 wherein the ring has a cross-section selected from the group consisting of trapezoidal, semi-circular, triangular, cusped triangular, cusped trapezoidal, and inverted "T" shape.
Claim 9
Dependent Claim
16 words
The apparatus according to claim 6 wherein the cross-section of the ring has a trapezoidal shape.
