Definitions

  • the present invention relates to a 50 ⁇ connector for connection of coaxial cables, more especially intended for applications of radio transmission.
  • This connector was developed in view of a need emerging in the field of wireless telephony.
  • This technology is currently in full swing, that subscribers are connected by radio to a base station integrated into the network (DECT system).
  • DECT system integrated into the network
  • RFP base station
  • CTA box subscriber
  • This cable coaxial despite its low cost, has the advantage of being relatively efficient in the frequency range useful radio, since its linear loss is is around 0.3 dB / m. However, overall the adaptation of the link remains poor: around 19 dB average ROS (ratio of transmitted power to the reflected power).
  • the invention therefore consists of a coaxial connector 50 ⁇ for radio frequencies, characterized in that it includes a socket-type female part intended for be mounted at the outlet of equipment such as a housing electronic, at the end of a coaxial cable of said equipment, and a male part for connection to a outdoor coaxial cable, female and male parts comprising tubular metallic bodies locking at the end of each other by means of a nut and ensuring the electrical connection of peripheral conductors of said coaxial cables, while the electrical connection between the central conductors of these is provided by a male part pin cooperating with pliers tubular of the female part, the end of connection of the female part being an end edge an external chamfer, applied during locking against an annular surface at the end of connection of the male part.
  • FIGs. 1a and 1b represent a 50 ⁇ connector according to the invention, designed to connect a coaxial cable C2 outdoor (50 ⁇ cable as above reference CO150af from Bieffe S.R.L.) to that C1 of equipment, for example in a telephone installation, a CTA subscriber unit within the link between it and the antenna.
  • a coaxial cable C2 outdoor 50 ⁇ cable as above reference CO150af from Bieffe S.R.L.
  • the socket-type female part 1 is designed for be mounted across a wall. It involves therefore a metallic tubular body 10 having in its rear end 11 a rear support flange 13 and, in front of it and up to its front end of connection 12, an external thread intended for the screwing in a mounting nut 14 and a connection lock 55 being part in this example of the male part 5.
  • the front end 12 of the body 10 has a outer chamfer 12a, and ends with a lip 12b surrounding the orifice of the internal bore 15 of the body 10.
  • the bore 15 has a first at the bottom shoulder 16, then a second shoulder 17 around a rear outlet port 18.
  • the volume of the bore 15 is fully occupied by a metal rear cap 20, and in front of it, a dielectric block 23.
  • the base 20 is housed intimately between the shoulder 16 on which it rests and the shoulder 17. Its part rear forms a connection tail 21 passing through the orifice 18 and projecting axially at the rear of the body 10.
  • the base 20, with its connection tail 21, has an axial passage channel 22, with a diameter of the internal dielectric of the coaxial cable C1 to connect.
  • the dielectric block 23 at the front of the base 20 in the bore 15 is in abutment against the shoulder 16. It is blocked by crimping the lip 12b on its front end. It has a central bore in which a contact element 25 is inserted.
  • connection tail 21 being fitted in the peripheral conductor and the sheath external fixed by means of a crimp ring 26.
  • the male part 5 comprises a tubular body 50 having at its front end of connection 51 an external collar 52 and an internal return 53 defining an axial orifice 54 bordered on the outside by an annular transverse surface 51a.
  • the flange 52 serves as a stop for the base of the aforementioned locking nut 55 which is engaged free rotating on the body 50.
  • the part rear of body 1 is shaped, with projections peripherals, so as to constitute a tail of connection 56 for the peripheral conductor and the external sheath of a C2 cable to be connected.
  • the tail of connection 56 is limited towards the front by a peripheral shoulder 57.
  • the body 50 Internally, from its rear end 58 until the return 53, the body 50 has a bore 59 diameter corresponding to that of the dielectric inside of the C2 cable to be connected. Bore 59 is empty in its major part, namely that it does not contain in the background, pressed on the return before 53, that a small dielectric block 60 intended to carry the element of axial contact, here being a pin 61 whose front part 61a projecting externally is shaped for maximum quality contact in the clamp 25 of the female part 1.
  • the block 60 generally has the form of a thick ring wedged at the bottom of bore 59 and defining an axial passage channel for the spindle 61.
  • Pin 61 has a tubular rear part 61b of larger section than that of the front part 61a, and separated from the latter by a shoulder 61c.
  • the pin 61 is engaged by its front part 61a in the block 60, the rear wall of which constitutes a support for shoulder 61c.
  • connection part 56 of the body 50 are advantageously substantially in the same plane transverse, in order to allow and facilitate the C2 cable connection with the necessary precision to obtain the expected performance.
  • the review of the Fig. 1b indeed shows that despite the simplicity of structure and the small number of parts of the part male 5, the assembly cooperates so that the connection of the cable can only be carried out optimally in compliance with better positioning conditions relative between the various elements.
  • connection quality is excellent for both internal conductors of cables through the pin clamp assembly only for their peripheral conductors through the base 20, the body 10 of the female part and the body 50 of the male part, with increased contact quality between connection ends 12 and 51 due to the chamfer 12a on the end of the female part.
  • Fig. 2 illustrates an improvement made to the male part 5 of FIG. 1b, this improvement consisting of that the ferrule 62 is provided here in as an integral part of the body 50, defining so with the rear part forming tail connection 56 a deep annular groove of receiving the peripheral conductor and the sheath cable C2.
  • the wall of the ferrule 62 advantageously presents in its part before, that is to say at the bottom of said groove, one or more small openings 62a to function viewing window to check the assembly C2 cable correct when connected.
  • the front end 12 of the part female always has an external chamfer 12a, but which is extended here by a right interior return 12c instead of the lips 12b in the example of the Fig. 1b.
  • the parts inside the body 50 are then put in place from its rear end, a crimping lip being closed on the edge rear of the base 20 and blocking the assembly.
  • FIG. 3 also represents its lock nut 55 with a peripheral groove 55a intended to receive a seal 65 to establish the seal between on the one hand the chamfered surface 12a of the female part 1 and, on the other hand, the flat annular surface of the end 51 of the male part 5.
  • the male part 5 'further comprises means sealing at its rear end, in the form of cable gland.
  • the rear part 56 ′ of the body 50 ′ is threaded for receive the gland nut 66 '.
  • the internal bore 59 ' in its rear part, the internal bore 59 'has a first shoulder 67' for wedging of a dielectric annular block 69 'retaining the rear end of the spindle 61 ', and a second shoulder 68 'for wedging, behind block 69', a connection tail 70 'separated from the body 50', but intimately involved in it to ensure good electrical continuity between them.
  • a free space is provided in the body 50 'around the rear part of the spindle 61', between the front block 60 'and the block 69'.
  • connection tail 70 ' engaged in the body 50 'forms a collar limiting the connection part proper, and against which the sealing ring 71 'of the cable gland.
  • the dielectric inside the latter, engaged in the connection tail 70 ' comes to bear against the rear wall of block 69 '.
  • the arrangement of the male part 5 ′ is such that it is very easy to mount the cable C2 at best.
