[0001] This invention relates to a coaxial connector coupling unit which has means for effecting electrical connection between the outer bodies of two mateable coaxial connector units.
[0002] Figure 1 is a schematic illustration showing a conventional connector configuration of a type known to us in which a pair of coaxial connectors each having an inner terminal 1, 2 and an outer body portion 3, 4 coaxial with the inner terminal. The inside diameter of one of the outer body portions 3 of one of the connector units is slightly less than the outside diameter of the other body portion 4 and the latter body portion has slits 5 in the axial direction to provide resilient integral contact tines 6 which ride over the body portion of the other mateable connector unit to electrically interconnect the two body portions as the inner terminals are brought into electrical contact. The inner terminals 1 & 2 may be formed by plug and socket elements. Such connector units may be designed to permit the inner terminal 1,2 to be connected to the central conductor of a coaxial cable and the cylindrical outer body portion 3, 4 to be connected to the outer screen of the electrical cable or the connector units may be adapted for mounting on a printed circuit board or chassis unit such that both inner terminal and outer body can be coupled to a circuit on the board or in the chassis and permit connection with a cooperating connector unit.
[0003] The construction described in relation to Figure 1 requires the use of high tensile strength material and involves complex machining of the bodies.
[0004] European Patent Specification Number 0450988A1 describes a coaxial connector coupling unit, comprising a housing having an aperture to permit insertion of a mateable coaxial terminating unit having an inner terminal and an outer body, the housing having at least one electrically conductive resilient element, in the form of an elongate finger (languette 10, 310) which is located, in the housing and so arranged as to make resilient electrical contact with the outer body of the terminating unit upon insertion into the housing.
[0006] According to the invention there is provided a coaxial connector coupling unit, comprising a housing having an aperture to permit insertion of a mateable coaxial terminating unit having an inner terminal and an outer body, characterised in that the housing has at least one electrically conductive resilient element having opposite edge formations which are located or locatable, in the aperture in oppositely disposed recesses provided in the walls of the housing and so arranged as to make resilient electrical contact with the outer body of the terminating unit upon insertion into the housing.
[0007] By providing a housing having one or more resilient electrical contact capable of electrically connecting the outer body of a coaxial termination unit the construction of such a terminating unit can be simplified.
[0008] The or each electrically conductive resilient element may be an elongate finger which is shaped such that when located in the housing it is disposed along the aperture. The elongate finger/s may be provided, at or near one end, with the edge formations in the form of two oppositely disposed outwardly extending lugs which are locatable in a pair of recesses which are disposed at the periphery of the housing.
[0009] The housing may be provided with a blind retention groove at the end of the aperture which permits shielding of the end of the finger. The groove may extend along the housing at opposite sides of the periphery of the aperture and the opposite bottoms of the groove may be longitudinally inwardly tapered towards the blind end, and the finger/s may be provided on opposite edges with one or more barbs which cut into the sides of the grooves due to forcible insertion of the finger and serve to retain the finger therein. The or each elongate finger may be shaped such that, when located in the housing, one end is inclined inwardly towards the axis of the aperture and is displaceable outwardly by contact with the outer body of a terminating unit when inserted in the aperture from one end.
[0010] The aperture in the housing may be a through aperture to permit insertion from opposite ends of a pair of mateable coaxial terminating units each having an inner terminal and an outer body, the resilient elements being arranged to make resilient electrical contact with the outer body of each of the terminating units upon their insertion into the housing thereby to effect electrical connection between the outer bodies when the inner terminals are brought into contact.
[0011] Advantageously the elongate finger may be provided with a resilient tongue, towards the end opposite to said one end, which tongue is inclined at an acute angle to the finger in a direction towards said one end such that when the finger is located in the housing, the tongue presents an inclined resilient contact which is displaceable outwardly by contact with the outer body of another terminating unit when inserted in the aperture from the end opposite from said one end. The resilient element/s may be stamped from sheet metal.
[0012] Preferably, two resilient elements are employed which are oppositely disposed along the through aperture.
[0013] In one advantageous construction there is included a retention cap adapted for location on the housing at one end of the through aperture, which cap has a through aperture for a coaxial cable end the cap serving to secure a cable terminating unit in the housing. The retention cap may be secured on the housing by mutually cooperating latching elements.
[0014] The invention also includes a coaxial connector including a coupling unit, as previously defined.
[0015] In order that the invention and its various other preferred features may be understood more easily, an embodiment thereof will now be described, by way of example only, with reference to the drawings, in which:-
Figure 1 is a schematic illustration of an existing connector which is known to us and as previously described,

Figure 8 is a plan view of the resilient element in the form of an elongate finger shown in Figure 3,
Figure 9 is a side view of the resilient element of Figure 8,
Figure 10 is a perspective cut away view showing a coaxial cable terminating unit located in a coupling unit, and
Figure 11 is a perspective view of a terminating unit suitable for mounting on a printed circuit board and for mating with a connector coupling unit.
[0016] Referring to Figures 2 & 3 of the drawings a coaxial connector coupling unit comprises a housing 10 having a through aperture 11 which, as can be seen from Figures 6 & 7, has a partially circular cross section with oppositely disposed longitudinally extending rectangular extensions 12, 13, in each of which extensions there is removably located an electrically conductive resilient element 14. The resilient element is stamped from a sheet of metal, for example Beryllium Copper, and is in the form of a finger and its shape is illustrated in detail in Figures 8 & 9. The resilient element has at one end a pair of oppositely disposed projecting lugs 15, near to that end there is a pair of outwardly directed oppositely disposed barbs 16, and provided near to that end, a tongue 17 is formed so that it is inclined at an acute angle to the finger in a direction towards the other end. As can be seen from Figure 9 the finger is bent slightly downwardly from about its middle and is upwardly curved towards the other end. The fingers are each located in one of the rectangular extensions along the through aperture and the lugs 15 & 16 are engaged into oppositely disposed recesses 18, 19 provided at one end of the rectangular extensions. The recesses 18, 19 each adjoin a groove which extends longitudinally of the housing at the periphery of the through aperture oppositely disposed bottoms of which groove are inwardly tapered in a direction away from the recesses. The finger is retained in the groove in the housing by forced insertion of the barbs biting into the edges of the groove to prevent withdrawal. The other end of the finger is located in a blind groove 20 provided at the other end of the rectangular extensions of the through aperture as can be seen more easily in Figure 10. In this way the finger end is shielded to prevent damage upon insertion of a terminating unit. The tongue 17 presents a resilient contact which engages a cylindrical outer body surface of a simple coaxial terminating unit 21 which in the illustrated embodiment is of the type for terminating the end of a coaxial cable 25. The terminating unit has an inner terminal 22 coupled to the central conductor of the coaxial cable end and the body is coupled to the outer screen of the coaxial cable end. The body is secured to the cable by means of a crimping sleeve 23 and is retained in the coupling unit by a cap 24 which is releasably securable to the housing 10 by any suitable means, not shown e.g. screws or a latching arrangements such as lugs cooperating with latching recesses.
[0017] It will be seen from the assembled arrangement of Figure 2 that the connector coupling unit with the terminating unit installed presents at the open end of the through aperture an entry for a terminating unit similar to 21 having a terminal for engaging the terminal 22 and when such a terminating unit is inserted the extremities of the fingers which are inclined inwardly towards the opening will be resiliently deflected outwardly by the body of the terminating unit and will make electrical contact therewith. In this way good electrical contact between the bodies of each of the terminating units can be ensured.
[0018] The embodiment described employs two resilient elements which are oppositely disposed but a single element or more than two elements can be provided and in the latter case these may be equiangularly disposed around the through aperture.
[0019] The resilient element 14 could be stamped with two spaced oppositely extending tongues, like tongue 17, for cooperation each with one of the terminating units, instead of the finger being bent downwardly from its middle. Alternatively instead of providing a tongue such as 17 the resilient finger element 14 could be bent such that it extends axially inwardly towards opposite extremities and is located in spaced blind grooves similar to groove 20 so that it is retained in the housing and is resiliently deflected upon entry of a terminating unit to make electrical contact with the outer body. The resilient element may be formed such that the force exerted by a tongue 17, or the axially inwardly bent portion near the extremity of the resilient element, on the outer body surface of a first coaxial terminating unit, inserted from one end, is greater than that which is exerted on a second terminating unit, inserted from the other end, and retains the first terminating unit therein during insertion and coupling of the second terminating unit. Such an arrangement obviates the need for a cap 24.
[0020] Figure 10 shows a coupling unit formed in a housing which may form part of a larger electrical connector having additional coupling units and/or L.F. contacts to provide an integrated composite connector for coupling to a matable connector. The invention includes a connector having a coupling unit provided therein with, and without, a coaxial terminating unit mounted therein.
[0021] Referring now to Figure 11 there is illustrated a coaxial terminating unit which is mateable with a coupling unit such as that shown in Figures 2 & 3 or 10 and which is designed to mount on a printed circuit board and in a housing. The terminating unit has an inner coaxial terminal (not shown) which has an extension 27 which extends through cap 24 and is inclined downwardly for contact with or securement to the track on the surface of a printed circuit board. A base plate 28 is formed integrally with a conductive outer body 29 of the terminating unit. The base plate has a downward extension 30 which at its extremity is in planar alignment with the extremity of extension 27 to permit contact with or securement to a different track on the surface of the same printed circuit board.
[0022] A terminating unit such as is illustrated in Figure 11 may be provided in a coupling unit such as is shown in Figures 2,3 or 10 and the assembly may be mounted on a printed circuit board. In such an arrangement the coupling unit may be itself secured to the board or may be freely removable.
[0023] The coupling unit may be employed to couple two boards which are each provided with a terminating unit, such as is illustrated in Figure 11, by insertion of the termination units from opposite ends of the through aperture 11 such that their outer bodies are electrically interconnected via the resilient elements 14.
