Description

DESCRIPTION
INSULATING CONNECTOR CASING
FIELD OF ART
The invention relates to the field of antenna techniques and antenna systems, and more particularly to casings that are not mechanically closely associated with radiating elements.
BACKGROUND OF THE INVENTION
The insulating connector casing disclosed in the present invention has not been disclosed in the prior art.
Connectors are basic components widely used in any mobile telephony antenna system installation, but also in any interconnection of passive or active components to antenna systems of any technology or type of emission. The place of application of the connector to the relevant cable is a possible failure point, as at this point the cable insulation is interrupted. Weather conditions, especially rain, moisture and salts, are factors that can have a particularly negative effect on the components, thus affecting the quality and characteristics of the relevant connection. To date, solutions have been proposed to address these issues, including the boxing of connectors in casings. The casings are plastic and surround the connectors so that they are not directly affected by the environmental conditions. An additional suggestion includes the injection of gel into the interior of each casing to cover the space that remains free between the connector and the casing and insulate the connector even more effectively.
The solutions proposed to date have disadvantages, which make them problematic. At first, connectors do not all have the same dimensions, so they are not served by the same casing. As a result, the installer needs to be equipped with different casings and depending on the size of the connector to be protected, place the corresponding casing. Furthermore, the gel lying inside to fill the space between the connector and the casing is customary to polymerize due to weather conditions. Temperature variations, as well as change in prevailing conditions, often lead to destruction of the gel, which sticks to the connector, aggravating the problem, since it no longer acts as insulator.
A further disadvantage of the present solutions is the fact that the casings available have not a perimeter rim at their upper end where the cable passes through, so that the water accumulated therein is retained for a long time, gradually eroding the gel. Moreover, the water accumulation in direct contact with the gel and its penetration into the casing inevitably leads to the formation of salts, which contribute to faster loss of its insulating capacity, resulting in corrosion conditions and poor functioning of the connectors, changing and altering their dielectric characteristics.
Further disadvantageous features of the casings available so far are that the plastic is clamped directly around the connector without the presence of a rubber gasket which can mitigate the pressure when the casing is clamped onto the connector. Moreover, the existence of different casings for the different dimensional connectors also leads to an increase in construction costs.
It is therefore an object of the present invention to advantageously overcome the aforementioned drawbacks and deficiencies of the prior art by proposing an insulating connector casing with innovative technical features.
It is a further object of the present invention to provide an insulating connector casing which comprises a protective shell on which various resilient gaskets are applied to cover the known connector systems for antennas.
It is a further object of the present invention to provide an insulating connector casing having rubber gaskets which do not polymerize and which remain unaltered, thus not affecting the quality of the connections.
It is a further object of the invention to provide an insulating connector casing made of plastic which has ribs, thereby providing enhanced stress resistance and avoiding distortion. It is a further object of the invention to provide an insulating connector casing which, thanks to its rubber gaskets, absorbs the clamping pressure, preventing its transfer to the components it protects.
Another object of the invention is to provide an insulating connector casing, whose protective shell has an rim, on both the upper and the lower part, so as not to allow the accumulation of water or sludge from precipitation and to ensure that the insulating material that protects the components will not be corroded.
It is also an object of the present invention to provide an insulating connector casing which does not allow the accumulation of rain waters in the upper part of the casing to form salts and affect the connected components.
It is also an object of the present invention to provide an insulating casing which, irrespective of the diameter of the parts it covers, uses the same protection, thereby reducing manufacturing costs, since only a single die for the shell construction is required.
These and other objects, features and advantages of the invention will become apparent in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS
The invention will become apparent to those skilled in the art with reference to the accompanying drawings in which it is depicted in an illustrative, non-limiting manner.
Figure 1 is a perspective view of the insulating connector casing of the invention, showing both the protective shell and an exemplary rubber gasket thereon.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the accompanying drawings, we will illustrate exemplary embodiments of the insulating connector casing so as to highlight its particular technical characteristics as well as its advantages. The protection of wires and connectors for antenna systems installed in the open air is an important subject as any interference affects the quality and speed of communication and data transmission. The invention disclosed herein relates to an insulating connector casing which consists of a protective shell (1), Fig. 1 , symmetrical with respect to the vertical axis. The two symmetrical portions of the protective shell (1), Fig. 5, fold around the axle and enclose the components they ought to protect. The protective shell (1) is made of plastic material, suitable for use in outdoor applications, with resistance to temperature fluctuations from -40 to + 65oC. Internally, each part of the shell (1) has ribs (2) which enhance its rigidity as well as its resistance to the pressures exerted. Similarly, there also external ribs (2) for structural reinforcement.
Each part of the protective shell (1) internally has a semi-circular configuration to allow cable to pass and to provide the necessary space for accommodating the connectors and other components to be protected. The protective shell (1) is through its upper and lower sides. Inside the protective shell (1) in the space provided a suitable rubber gasket (3) is applied, Fig. 2. The rubber gasket (3) can be of different sizes to meet the requirements of the known size connectors available on the market. Indicative variants of the gasket are for type 4.3-10 connectors, Fig. 2, and 7/16 inch connectors, Fig. 3. Applying the appropriate gasket (3) ensures that the connectors will be best covered and protected from moisture, water and weather conditions in general. The elastic gasket (3) fits inside the parts of the protective shell (1) and is made of suitable rubber, which remains indestructible over time. In the casing where the connector placed within the protective shell (1) is of a small size, the rubber gasket (3) has a larger size to occupy the entire remaining space. On the contrary, for a larger connector, a smaller size rubber gasket (3) is used, allowing placement. The presence of the rubber gasket (3) ensures that the available space within the protective shell (1) is not exclusively covered with gel, which avoids polymerization as well as sticking the gel to the connectors.
The protective shell (1) parts have a frame (4) on the sides to which they join, which is used to be slidably applied by locking (5), Fig. 4. The locking means (5) is configured with ribs (6) and notches (7) partially or all over its length. Its shape follows the configuration of the protective shell (1) at the joining points, so that it is accurately closed. The sealing means (5) is detachable and may be removed when opening the protective shell (1) for inspection or relative repair of the protected components.
A particular feature and advantage of the insulating connector casing is the presence of a perimeter rim (8) on the top of the frame. The perimeter rim (8) prevents rain water or moisture from accumulating in the upper part of the protective shell (1) and consequently gradually eroding the gel that protects and insulates the components. It is understood that the locking means has a corresponding rim at the top to ensure complete perimeter protection of the upper part of the protective shell (1). The rubber gaskets (3) also have a rim at their upper part, following the configuration of the protective shell (1 ).
It should be noted here that the description of the invention was made with reference to exemplary embodiments, not being limited thereto. It is accepted that any change or modification in shape, dimensions, morphology, construction and assembly materials and components used, unless they constitute a new inventive step and contribute to the technical development of the already known one, are considered to be included in the purposes and contemplation of the present invention.
