Definitions

  • This invention relates to a coaxial connector such as is used for terminating the end of a coaxial cable to permit its connection to an electrical equipment or printed circuit board.
  • Coaxial cable connectors are well known and normally require a complex construction and difficult or time consuming cable terminating process.
  • One type of connector for coupling to a coaxial cable is described in International Publication No. WO 93/19498.
  • the central conductor of a coaxial cable is inserted in between coupling means of the connector, the coupling means being disposed in a transverse direction in the insertion direction of the coaxial cable.
  • Locking means are then engaged in the connector to force the coupling means to engage into contact around the central conductor of the coaxial cable.
  • the connector is arranged to accept coaxial cables of varying cross sectional dimensions.
  • the present invention seeks to provide a connector which facilitates termination.
  • a coaxial cable connector comprising a housing, adapted to receive a central conductor of a prepared cable end inserted in one direction, an insulating member being received within the housing and having a bore for receiving the central conductor, characterised in that the connector further comprises an insulator provided with a terminal having a contact end, the insulator being insertable into the housing in a direction transversely of said one direction so that the contact end is brought into secure electrical contact with the central conductor located in the bore of the insulating member.
  • a retaining means may be provided which is effective to mutually secure the housing and the insulator with the electrical end in contact with the central conductor.
  • the retaining means may comprise cooperating latching means on the housing and the insulator.
  • the latching means may have provision for latching the insulator in the housing in two relative dispositions, wherein in one of the two dispositions the contact end is spaced from a central conductor location to permit insertion of a cable, and in the other of the two dispositions the contact end can engage a central conductor inserted into the location.
  • the latching elements may comprise a cooperating projection and groove(s) mutually engageable to secure the insulator in the housing.
  • the contact end has a knife edge which is arranged to cut into the central conductor upon displacement of the insulator in the housing to the contact position.
  • the contact end may be forked so that it straddles the central conductor upon displacement of the insulator in the housing to the contact position.
  • Inner opposing edges of the forked end may be knife edges which are arranged to cut into opposite sides of the central conductor upon displacement of the insulator in the housing to the contact position.
  • the housing may be adapted to locate the central conductor with its insulating sheath, and the contact end may be arranged to penetrate the sheath to make electrical contact with the central conductor.
  • a separate insulator element may be provided which is locatable in the housing and which is formed to locate the central conductor.
  • the housing may be formed from metal or from an insulating material having a metallising outer coating and may be provided with means for electrical connection of the screen of the electrical cable to the metal housing or metallising coating.
  • a projection forming the cable entry end may be provided which is shaped to permit securement of the screen of the cable by crimping.
  • a metal housing 10 has a hollow rectangular body 12 having two cylindrical projections 14, 16 which extend substantially at right angles.
  • the projection 14 serves to receive an insulator 18 formed of a plastics material with an integral terminal 20 having a contact end 22 which is fork shaped and preferably has opposing edges of the fork formed as knife edges.
  • the cylindrical projection 16 serves to receive a prepared end of a cable 24 in which an outer sheath 26 is stripped back to reveal a screen 28 and an inner sheath 30 whilst the inner sheath is stripped back to reveal an inner conductor 32.
  • An insulator element 34 is of circular cross section having a bore 36 extending diametrically therethrough.
  • a slot 38 extends diametrically from one end of the element and intersects the bore 36.
  • the diameter of the insulator element is such that it permits insertion through the cylindrical projection 14 into the hollow rectangular body 12.
  • the insulator is provided with radially outwardly extending lugs 40 which are an interference fit in the body 12 so that the insulator is a press fit in the body.
  • the press fit is arranged such that the bore 36 aligns with the axis of the cylindrical projection 16 to permit insertion of the central conductor 32 when the cable is introduced to the cylindrical projection 16. It will be seen that the groove 38 is then aligned with the contact end 22.
  • the insulator 18 is provided with one or more radially outwardly extending projections 44 which are tapered towards the contact end 22 and have an abrupt rear face 44.
  • projections cooperate with radially outwardly extending grooves 46 and 48 which are provided in the inner wall of the cylindrical projection 14.
  • the insulator 18 is inserted in the cylindrical projection 14 and is located therein by the latching action between the projection(s) 42 and the recess 46 such that the assembly is retained in a disposition suitable for insertion of the prepared cable 24 with the contact end 22 spaced from the insulator element 34.
  • the cylindrical projection 16 has on its outer surface peripherally extending ribs 50.
  • the cable 24 In order to terminate the cable 24 it is first prepared by stripping back the outer sheath and the inner sheath to the form as illustrated in Figure 1.
  • the central conductor and it inner sheath is then introduced through the cylindrical projection 16 such that the inner conductor 32 enters into the bore 36.
  • the insulator 18 is then depressed into the cylindrical projection 14 such that the forked contact end 22 is caused to straddle the inner conductor 32 and cut into opposite sides of the central conductor and is secured in that position by snap engagement of the projection 42 in the recess 48.
  • the outer screen 28 of the cable 24 is then laid over the ribs 50 of the cylindrical projection 16 and is secured thereto by crimping.
  • the housing may be formed from an insulator by for example moulding and provided with a metallised outer coating for connection to the screen 28. It is also possible for the insulator element 34 to have a bore sized to receive the central conductor 32 together with the inner sheath without that sheath having been cut back. In such circumstances the contact end must be designed as an insulation displacement contact such as for example the fork end illustrated having opposing edges of knife shaped to penetrate the sheath and make electrical contact with the central conductor.
  • the screen 28 is shown to be secured by crimping any other suitable means of connection can be employed for example a clamping collar or securing screw. In the case of a housing formed from an insulating material, the insulator element 34 could be dispensed with and the features thereof could be integrated in the housing construction.
