Definitions

  • the present invention utilizes a tubular, unitary spring element carrying spring fingers that are reversely bent into U-shapes.
  • the U-shapes flatten in compression in a space concentric and between the first and the second coaxial connector assemblies.
  • the spring element is inherently self-limiting in deformation, providing an assembly functioning with fewer parts than a previous assembly.
  • a dielectric plug for a coaxial connector includes concentric cylinders or sleeves, that combine with an air space or gap concentrically between the sleeves to provide a composite dielectric compensating for impedance mismatch.
  • the sleeves are made thin for resilient flexure into the air gap to facilitate press fit assembly of the outer sleeve into a connector shell and press fit assembly of a center contact into the inner sleeve of the plug. The resilient characteristics of the sleeves permit assembly without damage of the assembled parts.
  • a coaxial electrical connector assembly of the present invention includes, a solid dielectric plug with a forward portion and inner and outer concentric sleeves joined integrally with the forward portion, a passageway extending axially through the forward portion and through the inner sleeve and adapted for receiving the center contact, and a dielectric air space extending between the sleeves, the sleeves adapted for resilient flexure and deflection into the space upon force fit assembly, respectively, with a conductive outer shell and a conductive center contact of the coaxial electrical connector assembly, a hollow spring element within the shell, the dielectric plug force fit within the spring element, a passageway extending axially through the plug, the conductive center contact force fit within the passageway and connected to a center conductor of the cable, and resilient spring fingers on the spring element, of the fingers being doubled back on themselves to provide inner and outer spring leaves distributed against the inner periphery of the shell at the mating end and adapted for resilient compression against the inner periphery of the shell upon surrounding and resiliently engaging a complementary portion of another coaxial
  • an object of the present invention is to provide a kit of parts for a coaxial connector assembly of relatively few component parts.
  • An object of the present invention is to provide a kit of parts for a coaxial connector assembly which comprises economically produced, stamped and formed contacts and drawn body members.
  • a further object of the present invention is to provide a coaxial connector assembly kit of parts which provides for convenient assembly, and which comprises improved spring retention means and further means for protecting said spring retention means.
  • a further object of the present invention is to provide a coaxial connector assembly kit of parts which is economically and readily produced; and readily assembled.
  • a further object of the present invention is to provide a coaxial connector assembly kit of parts including a dielectric plug having means to facilitate resilient press fit of the plug with other component parts of a coaxial connector assembly.
  • a further object of the present invention is to provide a dielectric plug with improved means to facilitate resilient retention of a contact body therein.
  • Another object of the present invention is to provide a dielectric plug facilitating press fit into an outer connector shell, and press fit of a contact member into the dielectric plug, and means compensating for impedance mismatch caused by cable termination with the shell and contact member.
  • the subject invention comprises coaxial connector components, including, a hollow tubular conductive spring element 2 having an axial passageway 3 extending therethrough, a dielectric body 4 having an axial passageway 5 extending therethrough, a conductive outer shell 6 having an axial passageway 7 extending therethrough, a conductive center ccntact 8, and a conductive crimping ferrule 10.
  • a coaxial transmission cable includes, a center conductor 12, surrounded by a dielectric layer 14, in turn, surrounded by an outer conductive shield 16 and an outer insulative sheath 17.
  • the tubular spring element 2 includes a rearward cylindrical portion 18 of relatively smaller diameter, and a larger diameter, forward cylindrical portion 2*0 integrally joined to portion 18 by a shoulder 19.
  • a plurality of annularly spaced apart spring fingers 22 are integral with the cylindrical portion 20, and project forwardly therefrom.
  • Each spring finger 22 constitutes an inner leaf 24, integrally joined to the cylindrical portion 20, and is reversely curved to form a U-shaped forward end and an outer leaf 26.
  • the inner leaf 24 is further provided with a radially projecting detent ridge 28.
  • the spring element 2 is stamped and formed in a manner well known in the industry.
  • the dielectric body 4 is of unitary construction and includes a forward cylindrical sleeve 30 joining rearwardly disposed, coaxial, outer cylindrical sleeve 32 and inner cylindrical sleeve 34.
  • the coaxial sleeves, 32, 34 are coaxially and radially spaced apart by an air space dielectric 33, as best seen in Figure 4.
  • the inner cylindrical sleeve 34 also provides an annular detent ridge 35 which projects radially into the axial passageway 5.
  • a rearward end of the dielectric body 4 includes an annular external projecting flange 36.
  • the outer shell 6 is of a unitary drawn metal construction, and includes a forward, relatively large diameter hood 38, joined by an internal shoulder 44 to an intermediate cylindrical portion 40, and a rearward smaller diameter portion 42.
  • the forward end of the hood 38 is provided with a rolled lip 66 projecting radially inward.
  • the center contact 8 is of electrical receptacle type and includes, a rearward crimping barrel 46, and having a bore 9, an intermediate portion with an annular retention groove 48, and a forwardly extending female receptacle portion 50.
  • the crimping ferrule 10 is provided at a rearward end with a crimp barrel 52, and at a forward end with an outwardly directed annular flange 54.
  • the dielectric body 4 is press fit into.the spring element 2, with the flange 36 exposed from the rearward end of portion 18 of the spring element 2.
  • the air space 33 allows the outer sleeve 32 to be thin and thereby possess resilient spring characteristics and to undergo resilient flexure and deflection into the air space when the sleeve 32 is press fit into the spring element.
  • the spring element and body 4 are assembled into the shell 6 from a forward end thereof.
  • the spring element is press inserted into the forward end of the hood 38. Thereafter the radially inward lip 66 overlies the U-shaped portions of the spring element 2 and retains the spring element in the shell body 6.
  • the coaxial cable is extended through the crimping ferrule 10, and has its exposed conductor 12 forwardmost, followed, in turn, by the exposed dielectric layer 14, and an exposed forward length of the outer conductive shield 16.
  • the center conductor 12 is inserted into the bore 9 of the crimp barrel 46 of contact 8, and connected by crimping in a conventional manner.
  • the center contact 8 is inserted into the dielectric body passageway 5, and is retained therein as the ridge 35 snaps resiliently into the groove 48 of the contact. It will be appreciated that the contact 8 causes resilient flexure and outward deflection of the inner sleeve 34, into the space 33.
  • the air space 33 allows the inner sleeve 34 to be made thin and thereby possess resilient spring characteristics that provide resilient retention forces for retaining the center contact.
  • the air space 73 provides an air dielectric coacting with the solid dielectric sleeves 34, 36 compensating for impedance mismatch caused by the plurality of connections of the coaxial cable with the shell 6 and contact 8 of the connector assembly.
  • the rearward portion 42 of the shell body 6 is inserted beneath the outer conductive shield 16 of the coaxial cable, and the crimping ferrule 10 is transported forwardly to entrap the exposed portion of the conductive shield radially against portion 42 of the shell.
  • the crimping ferrule 52 is radially crimped in a conventional manner.
  • the above described coaxial connector assembly intermates with a complementary coaxial connector assembly 56, comprising a center contact of male pin form 58, an outer conductive shell 60, and a dielectric body electrically isolating the shell 60 from the center pin 58.
  • the outer conductive shell 60 is provided with an annularly extending retention channel 64 spaced a prescribed distance rearwardly from the forward end of the assembly 56.
  • the separate assemblies shown in Figure 4 are shown intermated in Figure 5.
  • the forward end of the shell 60 is situated adjacent the inner end of the hood 38.
  • the rolled lip 66 provides a lead-in for guiding the shell 60 centrally of the inner spring leaves 24, and avoids stubbing of the shell 60 against ends of the spring fingers 22.
  • the lip 66 also provides a stop against which the shell 60 engages to limit the degree to which the assembly 56 can be laterally manipulated during or after mating.
  • the rolled lip 66 protects the spring fingers 22 from stubbing and excessive deflection by the assembly 56.
  • Figure 6 illustrates a pair of additional coaxial connector assemblies, similar to the assemblies previously disclosed, but with no lip 66 and thereby no protection for the spring finger portions 24 when the additional assemblies are intermated.
