DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to connector housings for coaxial cables and in particular to connector housings for surrounding a cable TV connection.
Connector housings for the protection of radio frequency cable connections such as tap or drop-off terminals are known from U.S. Pat. No. 4,998,894. These prior art housings contain an environmental sealing material usually a gel, which is held by the housing around the connection.
A problem associated with the above prior art housing is ensuring that the gel flows sufficiently to protect all parts of the connection when the housing is assembled around the cable and connection.
SUMMARY OF THE INVENTION
The present invention seeks to provide a cable connector housing with environmental sealing.
According to the present invention there is provided a cable connector housing for surrounding and sealing coaxial cable connections, the housing comprising at least two elongate body portions for surrounding the cable and connector, one end of the housing having a smaller opening for accommodating the cable and the other end having a larger opening to accommodate a connector, said one end or other part of the housing being shaped to force sealing means within the housing towards said other end of the housing when the elongate body portions are assembled around a connection.
Preferably said one end of the housing has a frusto-conical configuration.
The two housing body portions may be hinged together along one pair of longitudinal edges, and preferably the two edges have a snap fit connection.
The housing may be provided with a sealing means located within each body portion, or the sealing means may be provided separately. There is provided an in-line cable connector housing for in-line connection between two coaxial cables, the connector comprising two housings of the above type linked together at their said other ends by an annular collar.
The invention further provides a kit-of-parts for environmentally protecting a coaxial cable connection; and comprising at least one housing of the invention and a sealing material to be contained within the housing .
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be described by way of example and with reference to the accompanying drawings in which:
FIG. 1 is a view of the cable connector housing of the present invention showing the two body portions when fully open;
FIG. 2 is a section on the line II--II of FIG. 1;
FIG. 3 is a section on the line III--III of FIG. 1;
FIG. 4 is a schematic drawing showing one body portion in location around a cable connection;
FIG. 5 shows an isometric view of an in-line connector housing;
FIG. 6 is an isometric view of the connecting collar of FIG. 5 in the closed condition, and
FIG. 7 is an isometric view of the connecting collar in the open condition.
DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1 to 3, there is shown a cable connector housing 11 comprising elongate body portions 12 and 13. The housing 11 when in an assembled condition is substantially tubular having at one end a smaller diameter inlet port 14 to allow a coaxial cable to pass into the housing 11, and the other end 15 is open to accommodate a coaxial connector.
The two body portions 12 and 13 are linked together along one pair of longitudinal edges 16 and 17 by a living or other integral hinge 18 so that the hinge 18, and body portions 12 and 13 form a single piece which may be moulded from a plastics material such as nylon 66, or polypropylene. The other pair of longitudinal edges 21, 22 interconnect when the housing is in a closed condition and may be maintained in a closed condition by means of a snap-fit connector. The snap-fit connector comprises axial spaced detents 23 on the radially outer surface of the body portion 12 spaced along the longitudinal edge 21, and similarly spaced teeth 24 on the radially outer surface of the other body portion 13 which are held at the ends of resilient tangential arms 25. The resilient arms 25 flex sufficiently for the teeth 24 to ride
