Definitions

  • This invention relates to a male F-connector, particularly one with improved screening in relation to electromagnetic signals.
  • F-connectors are connectors used with coaxial cables typically in television, cable television and broadband cable networks.
  • the F-connectors are used in male/female pairs, with the male connector using a solid conductive inner wire of a coaxial cable as its pin.
  • the pin is inserted into a female F-connector to establish a connection between the coaxial cable and processing circuitry relating to a device or equipment connected to the female F-connector.
  • Coaxial cables distribute radio frequency signals around a network and are configured to provide very good electrical screening to the inner conductive wire.
  • a high level of screening is needed to ensure no signal leakage from the inner conductor through the coaxial cable casing and to ensure that unwanted signals cannot enter the coaxial cable casing and introduce noise to the wanted signal carried by the inner conductor.
  • connectors must be attached to ends of the coaxial cable to allow it to be connected to complementary connectors on other items of equipment.
  • the coaxial cable and connectors are constructed in such a way to try and keep unwanted signals from out of the signal transmission line.
  • problems arise with unwanted signal ingress where connector fixings loosen and allow signal ingress.
  • a male F-connector comprising a body adapted to receive a coaxial cable and a contact surface comprising a base being a disc with a central aperture and having an annular circumferential lip to define a cylindrical receiving portion capable of receiving a female F-connector, wherein a resilient electrically conductive ring is located within the cylindrical receiving portion.
  • the annular lip may have a depth of between 4 to 8mm, preferably 4 to 7mm, where depth is the dimension extending parallel to a longitudinal axis of the body.
  • the resilient electrically conductive ring may be in the form of a ring spring such that when the male F-connector is used with a complementary female F-connector, the ring spring urges against the female F-connector and lip to ensure good electrical connection is maintained between the contact surface and a mating female F- connector.
  • a male F- connector comprising a body adapted to receive a coaxial cable, a contact surface capable of contacting a female F-connector and an internally threaded nut element capable of receiving a female F-connector, wherein the nut element has an integral securing means adjustable between a first position which allows the nut element to be placed over the contact surface and a second position to permanently fix the nut element to the contact surface.
  • the nut element is preferably configured to be pushed over the contact surface to irreversibly engage with the contact surface and so permanently fix the nut element to the contact surface.
  • the integral securing means comprises a deflectable portion moveable between a deflected position which allows the nut element to be placed over the contact surface and an un-de fleeted position which permanently locks the nut element to the contact surface.
  • the deflectable portion may be provided by an inwardly facing annular lip which is of particular advantage where the nut element is made of plastics material or other resilient material with the plastics material or resilient material allowing the lip to deflect as it is pushed over the contact surface.
  • the nut element may incorporate an annular groove in which a resilient ring member is located such that the ring member deflects inwardly as the nut element is passed over the contact surface and expands to an un- deflected position to lock the nut element to the contact surface.
  • Figure 1 shows a side view of a male F-connector
  • Figure 2 shows a partially solid three-dimensional view of part of a male F-connector to illustrate radiation leakage
  • Figure 3 is a section through a male F-connector according to the present invention
  • Figure 4 shows a perspective view of a ferrule used in the connector of Figure 3;
  • Figure 5 shows interconnection of a male F-connector in accordance with the present invention with a standard female F-connector
  • Figure 6 shows a three-dimensional partially transparent view of a nut spinner as attached to the ferrule
  • Figure 7 shows an alternative nut spinner and ferrule combination. Description
  • Figure 1 shows a male F-connector 10 comprising a front mating portion 12 for receiving a compatible female F-connector and a body portion 14 for receiving and securing coaxial cable 16 as can be seen in Figure 3.
  • the present invention concerns the front mating portion 12.
  • the body portion 14 and how it mounts to a cable may be of any type suitable for mounting to a cable and in particular can be a screw-on, crimp fitting or compression fitting configuration as shown in Figure 3.
  • a conventional male and female F-connector are connected to each other, if not connected tightly RF radiation can leak from the connectors by escaping along the loosened threads of the connectors and much more significantly as shown in Figure 2 by leaking out of the back of the male connector, see arrow 18.
  • Connector 20 comprises cable mounting body 22 in which in use coaxial cable 16 is secured by a compression fitting, ferrule 24 with annular lip 26 extending towards the front open end of the connector so as to define a cylindrical portion 28 within which a metal ring spring 30 is located and an internally threaded nut spinner 32 secured around and over ferrule 24 and lip 26.
  • Ferrule 24 and lip 26 are metal, normally plated machine brass.
  • Conductor 34 of coaxial cable 16 can be seen extending through a central aperture of disc-shaped ferrule 24 to form a pin of the male connector. When in use and fully tightened, the flat end of a mating female connector presses against the planar floor of ferrule cup 28 and connector 20 is sealed for RF radiation ingress or egress.
  • the depth of the thread on nut spinner 32 is sufficient to take two to four full turns of thread, although a nut spinner made of soft plastics material will require more turns of thread than metal. However the overall depth of thread will always be less than 3mm.
  • Ferrule 24 and associated annular lip 26 can be seen in more detail in Figure 4.
  • Lip 26 extends up the side of a mating female connector, as can be seen in Figure 5 which shows inter-engaging male 20 and female 37 connectors loosened by two turns.
  • ferrule cup 28 surrounds the end of the connector 37 and ensures RF radiation cannot escape behind ferrule 24 but rather is deflected back towards inter- engaging threads 33 and 36 of the male and female connectors respectively.
  • Inner spring 30 ensures that a good electrical connection is maintained between lip 26, ferrule 24 and the mating female connector, even upon loosening.
  • the male connector By having the cylindrical cup 28, the male connector still retains its electromagnetic shielding effectiveness for RF frequencies of up to 1.6GHz even if the engagement of the male and female connectors loosens. Thus when undone by up to two full turns, connector 20 retains Class A EMC screening performance.
  • Such a connector is designed to fit onto all standard coaxial cables with internal conductor thicknesses of up to 1mm and to be compatible with all female-type F connectors as defined in BS- EN 61169-24 2009.
  • FIGS 3 and 5 the invention is illustrated with reference to a threaded nut spinner 32 made of plastics material which comprises an inwardly facing annular lip 40.
  • the threaded nut spinner 32 is placed onto the rest of the connector from the front, with the deflectable lip 40 pushed slightly outwards as it travels along lip 26 and lip 40 restoring into an undeflected position behind ferrule 24 when it is fully located in the correct position.
  • a plurality of circumferentially equispaced channels 41 are formed in the nut 32 so that lip 40 is discontinuous and broken into individual lip portions to assist with deflection.
  • metal nut spinner 42 has an internal annular groove 44 in which a sprung lock ring 46 sits.
  • Cup portion 28' is modified to incorporate an external annular groove 48 and so provide a reciprocal groove for sprung lock ring 46.
  • metal nut spinner 42 On assembly of the conductor, metal nut spinner 42 is pushed from the front of the connector back towards body 22, sprung lock ring 46 compresses and deflects inwards within groove 44 to allow the nut spinner to be forced along and over cup 28 and when groove 48 is reached, lock ring 46 is free to expand to its undeflected position and so lock nut spinner 42 in a fixed position relative to ferrule 24'.
