Abstract A coaxial connector having integral central contact and dynamic retention portions, with a peripheral coaxial contact separated by an insulating element secured to both, the peripheral coaxial contact being secured also in an in-sulating housing.
Description
1 20~817 74424-50 COAXIAL CONNECTOR
Field of the Inventlon Thls inventlon relates to connectlng coaxlal conduits with other electrlcal components, such as are on prlnted circuit boards.
Background of the Inventlon The need to attach coa~ial condults to components carrle~ by circult boards has been me~ in the past by techniques lnvolvlng compllcated tooling, solderlng, or other cumbersome procedures. ~:
Summary o~ the Inventlon We have discovered that the combination of a central member having a coaxial central contact at one end and a dynamlc retention portion at the other end with an annularly positioned coaxial perlpheral contact and insulating means therebetween makes possible assembly with mechanical and electrical lntegrlty of a coaxial receptor to a prlnted circuit board without speclal tooling or soldering~
In a broad aspect, the lnvention provides a coaxlal 2~ connector comprislng an inner contact pin, an outer contact member, and an insulating member secured therebetween, said contact pin including away from a contact portion thereof a compllant portlon.

Fig. 5 is a side elevation view of said dielectric bush-ing.

Fig. 7 is a view a~ 7-7 of Fig. 6.
Fig. 8 is a plan view of the housing.
Structure _ As shown in Fig. 1, housin~ 10 ~molded from insulating plastic material) includes countersink ~2, hole 14, and counterbore 16.
Frictionally press-fitted in the outer periphery 18 of counter~ore 16 are sleeve 20 and dlelectric bushing 22, formed of 10% glass-filled polye~herimide plastic.
S]eeve 20 carries four integral blades 26, spaced 90 angularly about ~he sleeve axis, which blades slant inwardly toward the axis of sleeve 20, their tips just below hole 14, and diametrically spaced just less than the dlameter of hole 14. Sleeva 20 and blades 26 are stamped from a sheet of copper alloy (Olin C7025) subsequently nickel plated and formed into the configuration shown, the base portion into a cylinder (Flg. 7), sheet portions abuttlng at 30. Struck out from sleeve ZO are generally semicircular embossments 32, which seat against shelves 33 of half coun~erbores 34, two of which are fo~med, 180 apar~, in each receptor hole of housing 10.
Also integral with sleeve Z0, and origlnally a part of the same stamped sheet, are two compliant portions 36 (spaced ... : , :,: .
2~96~7 180 apart around slee~-e 20), with the usual compliant por-tion slot 38.
Dielectric bushing 22 includes body 40, interrupted cha~fer 42, central hole 44, and flange 46, which is fric-S tionally secured in housing 10. Surface 48 of body 40 alsofrictionally engages sleeve 20. The upper surface 50 of flange 46 supports sleeve 20.
Bushing 22 al90 includes interrupted cyllndrical por~
tion 56 which terminates downwardly in a~ interrupted-con-centric-circles-defined step 589 and counterbore 59.
Flange 46 includes a pair of pads 60 extendlng below a pair of grooves 62, which are like pads 60 defined by in-~errupted pairs of concentric circles. ~Pads 60 are relieved in vertical notches 64 therethrough.
The connector's center member 70 includes a coaxial inner contact portion 72~ a central portion 74 carrying circumferential sharp rib 76, 1ange 78 with annular flat upper and lower surfaces, and compliant pin portion 80.
Housing 10 (Fig. 8) includes four sets of holes and countersinks as shown in Fig. 1, as well as a central hole 90 and countersink 92, the latter for locating purposes.
Manufacture The connector may be assembled by first pressing center member 70 into dielectric bushing 40, rib 76 assuring a per-manent friction bit therebetween, until the top of flange 78 engages the upper surface of counterbore 59. Bushing 40 is then press-fitted into shell 20. This subassembly is then press-fitted into the cylindrical portion llO of counterbore 16.
The entire coaxial connector assembly, with iks four coaxial connector portions, may then be pressed into PCB
' - 4 ~ 2 ~ 9 6 ~ ~. 7 102, compliant portions 36 and 80 mating with appropriately oriented holes 100. ~either complicated tooling nor solder-ing is needed for this.
Force transfer in assembly into the PCB is through em-bossments 32, shell 20, flange 469 and flange 78.
Operation In operation, blades 26 p~ovide contact with the outer conductive portion of a coaxial electrical conduit, and pin 72 provides contact with the inner conductlve portion thereof.
The embossments 32 and the relat d shelves on which they si~ are positioned to angularly orient the connectors as desired to the PCB 102, as well as to limit axial move~
ment between shell 20 and housing 10.
Notches 64 permit passage of compliant portions 36, while flange 46 prevents contact of sleeve 20, with possible shorts, with PCB 102.
Other ~mbodiments Other embodiments within the invention will be ap-parent to those skilled in the art, or even unobvious.
For example, the housing 10 may receive fewer or more than four subassemblies.
Or, more or less than two compliant portions 36 may be provided on each sleeveO
The innsr contact may be made by progressive die stamp-ing rather than by machining.
Relieved portions 58 of bushing 22 affect its dielec-tric qualities favorably, in accordance with well-understood principles.
