Definitions

  • the invention concerns a pin coupling according to the preamble of claim 1.
  • a pin coupling which has a male cap and a female cap connecting them together through a projecting part on the male cap and a corresponding notch on the female cap.
  • the connection between the two co-axial cables and consequently between the two male and female connectors and the caps takes place in two phases.
  • First a connector is joined to the other one so that the male cap realizes a first locking between the male connector and the female connector.
  • the female cap is closed through an axial translation movement on the male cap by means of the snap tightening of the notch on the projecting part previously described.
  • a pin coupling of the now described type presents some limits of its functionality, due to the fact that the connecting and closing movements of the coupling takes place in two phases and, above all, because it is necessary to operate first by pushing the male connector and the female connector one against the other and then by pushing on the side of the female connector. It is evident that with the now described coupling the operator has to perform two different actions in a sequence.
  • the main purpose of the present invention is that of overcoming the inconveniences previously mentioned.
  • the first purpose is to realize a pin coupling such that the connection between the male connector and the female connector and the locking of the female cap on the male cap will occur by pushing the cable from one side only or by operating on the cap from one side only.
  • Another purpose of the present invention is to obtain a pin coupling with watertight characteristics, in order to prevent the water from damaging or altering the connection of the co-axial cable.
  • This aspect is particularly interesting, especially if the seal is realized in pin couplings which are used for connecting cables of car radio antennas. In that case, in fact, the pin couplings are exposed to bad weather and, therefore, it is important to realize a good watertight seal.
  • the co-axial cable, indicated with 1 is connected to a male connector, indicated as a whole with 2, which presents a central conductor 3 receiving the signal and which is separated from the outside metal screen 5 through an insulating material 4.
  • Said outside metal screen 5 extends until the rim indicated with 5a and presents also and elastic element 5b suited to ensure the contact with the corresponding metallic screening of the female connector, to which is connected and which is indicated as a whole with 6.
  • Said female connector, connected to the co-axial cable 15 presents a female contact 7 within which the male contact 3 of the male connector 2 is then coupled. Such a female contact 7 is separated from the outside metal screen, indicated as a whole with 9, through an insulating material 8.
  • Such a metal screen extends to the terminal part 9a projecting toward the coupling and it presents two annular projecting parts 9b and 9c, placed at such a distance that, as it will be observed hereinafter, they cooperate with the holding means belonging to the male cap 10 and the female cap 16 respectively of the pin coupling according to the invention.
  • the male cap is inserted in the female connector 2.
  • a male cap made of plastic material, locks itself on the connector lodging the same, through a projecting part 11 being present on the inner surface of said male cap, since such a projecting part 11 positions itself on a corresponding groove 111 obtained by performing a shrinking of the outside diameter of the metal screen 5.
  • the outer profile of the terminal part of the male cap 10 has the shape of a truncated-cone, as indicated in 12.
  • the male cap presents a flared connecting surface, indicated with 13, which precedes an annular recess 14 on which the projecting part 9b, belonging to the outside metal screen 9 of the female connector 6, positions itself when the coupling of the male cap 10 on the connector 12 is performed.
  • part 12 in the shape of a truncated-cone of the male cap has such a shape and thickness that the characteristics of elasticity of its plastic material are enhanced.
  • such a part 12 in the shape of a truncated-cone consists of sectors obtained through two or more longitudinal cuts.
  • there is a slight annular relief 101 which ensures the water tightness between the male cap 10 and the male connector 2.
  • the female cap indicated as a whole with 16, which is also preferably made of plastic material, presents an opening 17 with a wider diameter as compared to the opposite part which ends with a cylindrical element 18.
  • the profile of said female cap is initially cylindrical and then it continues with a conic section 17a which will then couple with the corresponding conic section 12 of the male cap 10.
  • the conic section 17a is followed by a cylindrical section 17b which ends with another cylindrical element 18 having a smaller diameter.
  • Said cylindrical element 18 presents, in correspondence with the rims, two internal annular projections 19 and 20 having such a diameter that they slidingly receive the metal screen 9 of the female connector 6.
  • the electric contact between the two male and female connectors 2 and 6 and the locking of the pin coupling consisting of the male cap 10 and the female cap 16 occur by pushing the cable 15 against the co-axial cable 1, after the connector 2 and the cap 10 have been assembled on cable 1, and after the connector 6 and the female cap 16 have been assembled on cable 15.
  • the male cap 10 couples with the female connector 9 through the coupling which is obtained between the annular recess 14 of the male cap 10 and the projecting part 9b belonging to the connector 6.
  • the internal annular projection 20 has an internal diameter such as to ensure the water sealing between the female cap 16 and the female connector 6. Another slight annular relief 171 on the female cap or on the male cap, obtains the water sealing between the male cap 10 and the female cap 6.
  • such a female cap on the side that couples with the male cap 10, presents an opening with a profile 21, having an essentially truncated-conic shape, with a wider diameter on the coupling side.
  • said female cap presents an essentially cylindrical section, indicated with 22, presenting a flared rim 23 ending with an undercut 23a.
  • the cylindrical section 22 presents an annular tailpiece with a conic shape profile 24, whose smaller diameter contrasts with the metallic surface of screen 9 belonging to the female connector 6.
  • annular tailpiece 24 contrasting with the surface 9, realizes the seal between said cap and said metallic surface.
  • annular relief 25 ensures the seal between the female cap 20 and the outer surface of the male cap 10.
  • the projecting part 9c of the female connector 6 is comprised between the flared rim 23a and the annular tailpiece with a conic shape profile 24.
  • Fig. 5 represents yet another embodiment of the invention concerning a different type of seal obtained through an OR sealing ring which guarantees the waterproof sealing by means of an OR ring inserted between the two metal screens of the two male and female connectors 2 and 6 which match each other.
  • a lodging, indicated with 26, for the accommodation of the OR ring is obtained, wherein said lodging is defined by the shrinking 51 of the inner diameter of the metal screen 5 on one side and on the bent section 52 of rim 5a of said metal screen on the other side.
  • the lodging for the OR ring can also be obtained with solutions differing from the one represented in Fig. 5, provided that said OR ring is lodged between the outer metal screens of the two male and female connectors.
