Definitions
- the invention concerns an arrangement of a sleeve, a coaxial cable and a female coaxial connector for coaxial connection coupable by pressure for telecommunication systems to be employed to couple in a quick and electrically perfect way a coaxial cable with a female coaxial connector, for example provided with an outer thread and a central contact, e.g. an elastic central contact of the F kind connectors.
- the technique already known generally provides, for the connection of coaxial cables with coaxial connectors, the welding or screwing of the two poles to the cable of the connector ends, or the screwing or crimping of the male coaxial connector on the screen conductor of the coaxial cable.
- the coupling of the cable with a connector is realised by screwing or by coupling or introduction of two metallic parts, a rigid one and an elastic one, respectively.
- a further object of the invention is that of realising a sleeve for coaxial connection allowing a connection between a coaxial cable and a female coaxial connector very easy to be realised, to be used without the need of any specific tool, with minimum sizes and very cheap.
- said first seat having an inner diameter (d1) corresponding to or slightly greater than the outer diameter of said cable and said second seat having an inner diameter (d2) slightly greater than the outer diameter of the outer wall of said female connector, and being realised by an elastic material, in such a way to obtain a pressure coupling of the outer screening conductor of the coaxial cable between the sleeve and the outer wall of the female coaxial connector, the connection zone between said first and second seats being realised by a sloped wall.
- At least one projection can be provided within said second seat.
- a circular projection can be provided outside said second seat, close to the outer connection zone with said first seat.
- spaced longitudinal ribs can be provided outside said second seat.
- longitudinal lugs can be further provided, preferably three lugs circumferentially spaced at 120°.
- longitudinal lugs can be further provided, preferably three lugs circumferentially spaced at 120°.
- said sleeve for coaxial connection is used for the connection of the coaxial cable screen made up of metallic braid, with the threaded outer screening of a female coaxial connector, or it is used for the connection of the coaxial cable screen made up of one or more metallic foils, with the threaded outer screening of a female coaxial cable, or still for the connection of the coaxial cable screen, made up of metallic braid and one or more metallic foils, with the outer screening of a female coaxial connector.
- said sleeve for coaxial connection can be made up with plastic material, elastic material, such as rubber, or elastic metallic material.
- the slidable sleeve for coaxial connection 1 is comprised of an integral body of material preferably semirigid or elastic, in the hollow inner part of which two coaxial cylindrical seats 2, 3 are obtained, said seats being connected by a sloped wall 4, and having the inner smaller diameter d1 corresponding to or greater than the outer diameter of the coaxial cable 20 used for the connection and the bigger inner diameter d2 slightly bigger than the outer diameter of the threaded surface or wall 41 of the coaxial connector 40 in order to allow to fix the screen 21 of the coaxial cable 20 between the threaded outer surface 41 of the coaxial connector 40 and the inner surface 5 having the diameter d2 of the slidable sleeve for coaxial connection.
- the cylindrical portion 2 of the sleeve for coaxial connection wounding the coaxial cable 20 is quite long, as shown in figure 1, in order to obtain a greater mechanical stability for the connection, or shorter, as shown in figure 2, to realise a connection in limited spaces, such as the embedded boxes for the fittings of the distribution systems of the radio TV signals.
- the inner surfaces of the sleeve for coaxial connection 1 according to the invention can be rough in order to increase the adherence of the sleeve for coaxial connection 1 with the outer sheath 22 of the coaxial cable 20 and with the threaded outer surface or wall 41 of the female coaxial connector 40.
- the circular opening 6 of the sleeve for coaxial connection 1 having diameter d1 ends with a flared part 7 making it easier to insert the sleeve for coaxial connection 1 on the terminal of the coaxial cable 20.
- the slidable sleeve sleeve for coaxial connection 1 can be provided in the inner part with projections 10 making it much more difficult to remove the female coaxial connector 40.
- the thickness of the slidable sleeve coaxial connector is a function of the dimensions of the coaxial cable 20 to be connected and of the material employed for the realisation of the sleeve for coaxial connection 1.
- the outer wall 11 of the slidable sleeve for coaxial connection 1 has a circumferencial ridge 12 to make it easier, by creating a grip upon which it is possible to exert a higher pressure with the hands, during the insertion and removal operations of the slidable sleeve for coaxial connection 1 from the female coaxial connector 40.
- Lugs can be provided within the seat 2, preferably three lugs at 120°, to avoid the sliding of the sleeve for coaxial connection 1 along cables having smaller diameter.
- the electrical features of the coaxial coupling are optimal; the concentricity and the complete screening of the connection are ensured by the immediate electric contact between the cable screen 21 and the outer surface or wall 41 of the connector 40, contact obtained immediately after that the screen 21 of the coaxial cable 20 is widened and detached from the dielectric 24 dividing the same screen 21 from the central conductor 23 of the coaxial cable 20.
- the sleeve for coaxial connection 1 further allows to make coaxial connection within small spaces, such as the space available within the usual connection blocks of the radio TV signal distribution systems provided within the houses.
- a further remarkable advantage is due to the low total cost of the coaxial connection that such a connector allows to realise, cost obtained adding the cost for the material of the connector with the cost of the labour necessary for the realisation of the connection: as it is evident from the above specification of the solution according to the invention and of its use, both costs are very low and in any case lower than the costs necessary to make a valid coaxial connection employing different connectors.
- the sleeve for coaxial connection 1 completely covers the connectors, protecting the same.
- Another advantage is due to the fact that the sleeve for coaxial connection 1 according to the invention can be used more than once in case it is necessary to make the connection again.
