Abstract
Abstract A housing for splicing a trunk cable to a plurality of tip cables has a detachable end cap for receiving the tip cables. The detachable end cap is constructed from a pair of attached molded sections having flat spaced parallel surfaces between which is positioned a rubber sealing member. A plurality of holes extend through the two sections and the sealing member for receiving the tip cables. The first section includes a plurality of integrally molded conically shaped knock-out members positioned in the holes of the first section and projecting through aligned holes in the sealing member and the second section. The knock-out members form a plug that substantially fills the associated holes of the sealing member. The knock-out members are removed from selected holes at the time of installation for receiving the tip cables into the housing.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
151 words
In a housing for splicing a trunk cable to a plurality of tip cables, a detachable end cap for the housing for receiving the tip cables comprising: a first member having a first plurality of holes of larger diameter than the tip cables, a second member having a second plurality of holes axially aligned with said first plurality of holes, a plurality of tapered conically shaped knockout members mounted in the holes in the first member at their larger ends and projecting through the holes in the second member at their smaller ends, the knockout members closing off the holes in the first member, and a sealing member of elastomeric material positioned between the first and second members and having holes aligned with the holes in the first and second members through which the knockout members project, the holes through the sealing member being smaller in diameter than the tip cables.
Claim 2
Dependent Claim
151 words
In a housing for splicing a trunk cable to a plurality of tip cables, a detachable end cap for the housing for receiving the tip cables comprising: a first member having a first plurality of holes of larger diameter than the tip cables, a second member having a second plurality of holes axially aligned with said first plurality of holes, a plurality of tapered conically shaped knockout members mounted in the holes in the first member at their larger ends and projecting through the holes in the second member at their smaller ends, the knockout members closing off the holes in the first member, and a sealing member of elastomeric material positioned between the first and second members and having holes aligned with the holes in the first and second members through which the knockout members project, the holes through the sealing member being smaller in diameter than the tip cables.
Claim 3
Dependent Claim
41 words
The housing and end cap of claim 1 wherein the knockout members where they pass through the holes in the sealing member are of slightly smaller diameter so to form a small annulus between the sealing member and the knockout members.
Claim 4
Dependent Claim
25 words
The housing and end cap of claim 1 wherein the holes through the sealing member are tapered in the same direction as the knockout members.
Claim 5
Dependent Claim
28 words
The housing and end cap of claim 3 wherein the sealing member is formed with a radially inwardly projecting lip at the smaller diameter end of each hole.
Claim 6
Dependent Claim
45 words
The housing and end cap of claim 1 wherein the first and second members engage each other around the outer periphery, the members having adjacent parallel spaced surfaces between which the sealing member is clamped, said holes extending with their axes perpendicular to said surfaces.
Claim 7
Dependent Claim
25 words
The housing and end cap of claim 5 wherein the distance between said parallel surfaces is substantially equal to the thickness of the sealing member.
Claim 8
Dependent Claim
96 words
In a cable splice housing for receiving a plurality of cables, means for admitting one or more cables into the housing, comprising inner and outer plates joined together around their margins and forming a portion of the housing, an elastomeric seal filling the space between the plates, the inner and outer plates and the seal having a plurality of axially aligned openings for receiving the cables, and a plurality of elongated knockout members secured in the openings in one plate, the knockout members projecting through the axially aligned openings in the seal and the other plate.
Claim 9
Dependent Claim
96 words
In a cable splice housing for receiving a plurality of cables, means for admitting one or more cables into the housing, comprising inner and outer plates joined together around their margins and forming a portion of the housing, an elastomeric seal filling the space between the plates, the inner and outer plates and the seal having a plurality of axially aligned openings for receiving the cables, and a plurality of elongated knockout members secured in the openings in one plate, the knockout members projecting through the axially aligned openings in the seal and the other plate.
Claim 10
Dependent Claim
30 words
The combination of claim 7 wherein the knockout members are secured to the outer plate and project through the openings in the inner plate into the interior of the housing.
Claim 11
Dependent Claim
20 words
The combination of claim 7 wherein the knockout members are tapered with the larger end secured to the outer plate.
Claim 12
Dependent Claim
21 words
The combination of claim 9 wherein the openings in the seal are tapered in the same direction as the knockout members.
Claim 13
Dependent Claim
32 words
The combination of claim 10 wherein the openings in the seal are larger than the knockout members whereby there is space between the knockout members and the surrounding openings in the seal.
Claim 14
Dependent Claim
16 words
The combination of claim 9 wherein the knockout members are molded integrally with the outer plate.
