Description
Kit of Parts for a Coaxial Connector Assembly There is known in U.S. 3,745,514 a coaxial connector assembly including a conductive split sleeve which expands radially upon mated connection with a second coaxial connector assembly. An annular ring accompanies the second connector assembly and surrounds the split sleeve, limiting its radial expansion.
The present invention utilizes a tubular, unitary spring element carrying sprinq 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 , 15 assembly~
;;l There is known in U.S. 3,67~,447 a coaxial connector assembly including a dielectric plug for supporting a conductive center contact of a coaxial connector assem~ly, and a projecting skirt on the contact for interference engagement within the plug. The plug is solid and provides only limited resiliency to facilitate force fit assembly with the center contact and skirt. Air space surrounds the plug and com~en~ates for impedance mismatch, caused by junctures of the coaxial cable conductors with component parts of the coaxial connector.

115~322 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~ integrally joined to portion 18 by a shoulder 19. A plurality of annularly spaced apart spring fingers 22 are integral with 1~ 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 for-~ard 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 rea~ardly disposed, coaxial, outer cylindrical sleeve 3~ 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.
Also, as shown in Figure 1, 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 ~y 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.
Returning to Figure 1, the center contact 8 is of ,' .
1 15~322 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 intD-.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.
As shown in Figure 4, the internal shoulder 19 of the spring element 2 abuts against the internal shoulder 44 of the shell body 6, and the outer leaf 26 of each spring finger 22 contacts the inner periphery of the hood 38.
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.
As illustrated in Figures 1 and 2, 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.
Collectively viewing Figures 2 and 4, the center 1 contact 8 is inserted into the dielectric body passageway 5, '~ and lS retained therein as the ridge 35 snaps resiliently ., :~ `

11$6322 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. Further, the air space 73 provides an air dielectric coacting with the solid dielectric sleeves 3~, 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.
Referring now to Figure 3, 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 co~ventional 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 detent ridge 28 of the spring fingers 22, after riding over the forward end of the outer shell 60, resiliently registers in the retention channel 64.
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. Thus, the rolled lip 66 protects the spring fingers 22 from stubbing and excessive deflection by the assembly 56.
It is to be understood that the above description of the invention is merely illustrative within the scope and spirit of the invention. Figure 6 illustrates a pair of additional coaxial connector assemblies, si~ilar 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.
