Face plate cover for outdoor in-line multitap

Abstract

An outdoor, in-line cable splitter or multitap is situated in a pedestal and connects a number of customer drop cables with an underground or buried main trunk cable or network cable. To avoid sharp bends in the customer cables, the face plate of the multitap has customer connectors that are bent downwards at an angle. In an example the customer drop connectors can emerge straight out at 90 degrees to the face plate and then angle down about 45 degrees. This allows room in the pedestal enclosure for the male connectors on the drop cables. The face plate can be exchanged for the corresponding face plate of a previously installed multitap.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

(5) With reference to the FIG. 1 of the Drawing, a conventional in-line splitter or multitap 10 has a casing or housing 12 on which is mounted a face plate 14 here held in place with a number of bolts or machine screws onto the front of the casing 12. Typically there are a number of circuit boards positioned within the casing or housing for processing and distributing broadband video, and as they are conventional these are not shown here. There are network cable ports 16 on the bottom and at the sides (for optional overhead installation) of the housing 12 and to these are connected the input side and the casing or housing. The face plate 14 has a number of customer ports 18 that project out, i.e., generally at a right angle to the face plate, i.e., horizontal in the case of a pedestal installation. Normally the customer drop cables (not shown here) would be installed one at each customer port to distribute the broadband video to various customer locations, e.g., homes and/or businesses. Because of the limited space within the pedestal, an installation of a standard multitap within a conventional pedestal can result in a sharp bend near the male connector of the drop cable, which may cause damage and/or signal loss. The usual solution to this is to use a jumper cable between the drop cable and the customer connector port 16, but this involves a lower quality cable for the jumpers, as well as additional connectors, which each contribute to insertion loss.

(6) As a solution to this is disclosed in an embodiment of this invention as shown in FIG. 2 which is an outdoor in-line multitap device having a case or housing 12 with network cable ports 16 as in the conventional multitap of FIG. 1, but with a face plate 24 with a plurality of customer ports 28, each having a base portion 30 extending out a short distance from the base plate 24 and an end female F type connector portion 32 that is angled down at an angle of about 45 degrees. This construction allows the male connector of the customer drop cable to be installed without the need for a jumper cable, and without creating a sharp bend in the cable within the tight spacing inside the pedestal.

(7) The face plate 24 of this embodiment is created at the same dimensions as the face plate 14 of the FIG. 1 multitap device 10, and is provided with fittings for threaded fasteners to match the corresponding casing or housing 12, so that the face plate 24 can be substituted for the existing face plate 14 in a previously installed video distribution pedestal. The face plate has electrical and signal fittings (on the reverse side of the face plate) to connect with the circuit boards within the existing casing or housing 12, making possible a simple conversion of the existing multitap by swapping out a replacement face plate for the existing one.

(8) FIG. 3 illustrates a typical outdoor arrangement for a pedestal installation, namely, a pedestal tower or enclosure 40 with a housing 42 formed as a vertically elongated housing of sheet steel construction, here with a cover 44 removed to show the interior. A multitap 20 is shown having the main housing 12 secured onto the back wall of the pedestal housing 42. The network cable 46 is shown with inlet and outlet sides respectively connected to the inlet and outlet ports 14 and running vertically down into the base of the pedestal 40. The pedestal cover 44 has been removed here, but can be replaced and locked to secure the pedestal after installation. The multitap face plate 24 has four customer outlet ports 28, each with the downward angled end connector portion 32 as illustrated earlier in FIG. 2.

(9) FIG. 4 is a side elevation of the face plate of this embodiment with the improved downward-angled customer ports 28. This face plate 24 is interchangeable with the existing or prior-art face plate 14, and is shown here installed on an existing or prior-art housing 12, drawn in broken line. Here two of the customer ports 28 are shown, with the remaining two ports obscured. The male connectors 52 of the respective customer drop cables 50 are connected at the downwardly oriented end connector portions 32. This face plate 24 and main casing 12 have a gasket 54 secured between them at a periphery of the casing 12 providing environmental seal, and favorably also an RF seal. The drop cables 50 are installed with the respective female end connectors 52 at a 45 degree angle so that each drop cable 50 can angle gently down to a vertical orientation, as shown, thus avoiding any sharp bend. FIG. 4 also shows the approximate location of the signal processing and distribution circuitry 58 within the main case or housing 12.

(10) In this embodiment there are four (4) customer connector ports 28 on the associated face plate 24, spaced two above and two below. However, any number of connector ports could be present on a given face plate, and commonly these may have two, six, eight, sixteen, or more customer ports.

(11) These out-door inline multitap devices may have other general shapes or configurations, but can be provided with downward angled female end connectors 32 to permit the associated drop cable to be easily connected at the (approximately) 45 degree downward angle, and to avoid sharp bends in the customer cable or crowding within the pedestal.

(12) There are many variations and modifications that would present themselves to persons of ordinary skill in the art without departing from the scope and spirit of the invention as defined in the appended claims.
