Abstract
Abstract A connector box for connecting the individual electrodes of a plurality of coaxial cables and especially useful as a splitter box for a television antenna lead-in comprises a two-part casing. Mating upper and lower casing members are cast with corresponding semi-cylindrical out-ward extensions which fit together when the two casing members are placed face to face to provide externally threaded tubular extensions onto which internally threaded collars of coaxial cable connectors can be screwed in turn to clamp such two casing members firmly together. Sleeve connectors are provided within the tubular extensions for effecting electrical connection to the core electrodes of the cables while connection between the sheath electrodes of the cables is usefully effected through the metallic casing of the connector box.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
242 words
A connector box for electrical connection to the individual conductors of at least one coaxial cable and which connector box comprises two separable electrically conductive casing members including mating peripheral walls for defining a box-like enclosure when said casing members are disposed in aligned, opposed and contiguous abutment with each other; at least one outward extension of open sectional configuration and integrally formed with said peripheral wall of each said casing member, said outward extension of one said casing member being disposed so as to mate with said outward extension of the other said casing member to form a hollow tubular extension of cylindrical configuration communicating with said box-like enclosure when said casing members are disposed in said aligned, opposed and contiguous abutment wiTh each other; and clamping means on said hollow tubular extension whereby said two casing members may be clamped in said aligned, opposed and contiguous abutment with each other, said clamping means comprising a coaxial cable connector having an internal thread in an electrically conductive collar and an external thread formed on said outward extensions so that, when said casing members are disposed in said aligned, opposed and contiguous abutment, said external threads on said outward extensions are operatively aligned for threaded engagement with the internal thread of the electrically conductive collar of a coaxial cable connector, electrical connection to the sheath electrode of the coaxial cable then being provided through said electrically conductive collar and said casing members.
Claim 2
Dependent Claim
242 words
A connector box for electrical connection to the individual conductors of at least one coaxial cable and which connector box comprises two separable electrically conductive casing members including mating peripheral walls for defining a box-like enclosure when said casing members are disposed in aligned, opposed and contiguous abutment with each other; at least one outward extension of open sectional configuration and integrally formed with said peripheral wall of each said casing member, said outward extension of one said casing member being disposed so as to mate with said outward extension of the other said casing member to form a hollow tubular extension of cylindrical configuration communicating with said box-like enclosure when said casing members are disposed in said aligned, opposed and contiguous abutment wiTh each other; and clamping means on said hollow tubular extension whereby said two casing members may be clamped in said aligned, opposed and contiguous abutment with each other, said clamping means comprising a coaxial cable connector having an internal thread in an electrically conductive collar and an external thread formed on said outward extensions so that, when said casing members are disposed in said aligned, opposed and contiguous abutment, said external threads on said outward extensions are operatively aligned for threaded engagement with the internal thread of the electrically conductive collar of a coaxial cable connector, electrical connection to the sheath electrode of the coaxial cable then being provided through said electrically conductive collar and said casing members.
Claim 3
Dependent Claim
68 words
A connector box as claimed in claim 1 which additionally includes a connector electrode supported in an electrically insulating sleeve disposed within said tubular extension, said connector electrode being adapted electrically to contact a core conductor of the coaxial cable when the collar of the coaxial cable connector is threadingly engaged with said tubular extension thereby to permit electrical connection to said core conductor within said connector box.
Claim 4
Dependent Claim
45 words
A connector box as claimed in claim 2 in which said peripheral wall of at least one of said casing members is provided with a flange adapted to abut said electrically insulating sleeve to restrict inward movement of said sleeve out of said tubular extension.
Claim 5
Dependent Claim
36 words
A connector box as claimed in claim 3 in which said tubular extension is formed with a flange adapted to abut said insulating sleeve to restrict outward movement of that sleeve out of said tubular extension.
Claim 6
Dependent Claim
34 words
A connector box as claimed in claim 4 and which includes at least three said tubular extensions to permit the conductors of a corresponding plurality of coaxial cables to be interconnected within said box.
Claim 7
Dependent Claim
45 words
A connector box as claimed in claim 5 intended for use as a splitter in a television antenna lead system and in which said connector box houses interconnected electronic circuit components adapted to provide coupling required between the individual coaxial cables connected to said box.
