Aug. 17, 1965 R. w. VOELCKER GOAXIAL LINE T0 STRIP LINE CONNECTOR Filed Dec. 30, 1963 INVEN TOR firyaezcze ATTORNEY United States Patent 0 i 3,2tllJ72i C51 rial, LEFT Til STPtllP MINE (JGNNECTQR iph W. Voelclaer, Greensboro, NC, assignor to "Western Electric Company, Incorporated, New York,

N311, a corporation of New Zora Dec. 31?, 1%3, der. No. 334,175 6 Claims. (Cl. SSS-$3} This invention relates to a coaxial line to strip line connector, and more particularly to a coaxial line to strip line connector having facilities for compensating for impedance mismatch and phase shift.

In certain applications, it is necessary to connect a coaxial transmission line (hereafter referred to as coaxial line) to a strip transmission line {hereafter referred to as strip line"). Usually as a result of such a connection, an impedance mismatch of the lines occurs and a phase shift is introduced into a signal being transmitted along the over-all line made up of the coaxial and strip lines. Sometimes impedance mismatch and phase shift are tolerable; however, in certain instances, it is critical that impedance mismatch and phase shift be corrected.

The usual procedure in the prior art for correcting this impedance mismatch and phase shift is to disconnect the lines from a connector and to machine the connector by trial and error; thereby altering the physical dimensions of the connector to adjust for impedance mismatch and phase shift. it is manifest that such a complicated procedure produces a connector tailored to operate only with a particular coaxial line and strip line.-

I The connector of this invention has adjustable facilities for compensating for impedance mismatch and phase shift. These adjustable facilities permit interchangeability of connectors and lines, compensation for impedance mismatch and phase shift without disconnecting the lines, and subsequent adjustments, if necessary, without complicated machining procedures.

An object of this invention is to provide a new and improved coaxial line to strip line connector.

Another object is to provide a coaxial line to strip line connector having facilities for compensating for impedance mismatch and phase shift.

With these and other objects in view, a coaxial line to strip line connector illustrating certain features of the invention includes a body portion having a cavity contained therein and facilities for connecting a coaxial line and a strip line thereto. Facilities are provided for tuning the cavity to correct for impedance mismatch and for adjusting the cavity to correct for phase shift.

Other objects and advantages of the invention will become apparent by reference to the following detailed specification and accompanying drawings, wherein:

FIG. 1 is a perspective View, incorporating certain principles of the invention, of a coaxial line to strip line connector having an upper body for receiving a coaxial line and a lower body for receiving a strip line; and

FIG. 2 is a cross sectional View of the coaxial line to strip line connector taken along line 2-4.. of FIG. 1.

In FIGS. 1 and 2 there is shown the coaxial line to strip line connector (hereafter referred to as connector) for connecting a coaxial line 11 and a strip line 12. Coaxial line 11 is representative of a wide variety of coaxial transmission lines and includes a center conductor 13 concentrically arranged within and electrically insulated relative to an outer conductor 14.

Strip line 12 is representative of a Wide variety of strip transmission lines and includes a fiat, center conductor 17 placed between a pair of dielectric sheets 1% which are secured to a pair of flat, outer conductors 19. Standard strip line 12 is modified in that a block or Wedge 2.1 is removable from the top of strip line 12 and is aligned with center conductor 17.

izfilflzl Patented Aug. 17, 1%65 The connector includes a lower body assembly 24 and an upper body assembly 26. Upper body assembly 26 comprises an outer sleeve 27 which is counterborcd at 28 to receive a collar 29 from which extends a threaded projection 39. The collar 29 is force fitted, staked, or otherwise secured Within the counterbored sleeve 27. The inner surface of the collar 29 is machined to form a wedging cone 31 into which is nested a split ferrule 32 having a conical outer surface. The sleeve 27 is provided with internal threads to receive an externally threaded inner sleeve 33 having an opening 34 and having one end formed in the shape of a bolt head 35.

An upper chuck 41 is mounted in a block 42 of electrical insulation secure-d within upper body assembly 26. Upper chuck ll has a beveled end 43 which communicates with the interior of upper body assembly 26 and a pin 4-4 which extends beyond projection 3t). A lock nut lb threadably engages and is adjustable in position along projection Ell.

Projection 3i! oi upper body assembly 26 is threaded into an internally threaded sleeve 47 forming a part of the lower body assembly 2 to define a tuning cavity 49. Tuning screws all extend through the walls of sleeve 47 and are adjustable in position within cavity 49. A lower chuck $2. is mounted in a block 53 of electrical insulation secured within the sleeve 47 of the lower body assembly Lower chuck 52 has an opening which receives pin id of upper chuck 41 and a flat tab '54 extending out of lower body assembly 24.

Clamping screws 64 are threadable through holes in legs as and or which extend from the sleeve 4'? of the lower body assembly 2 (FIGS. 1 and 2). Clamping screws as are aligned with holes in the end of strip line 12. A locking screw 68 (FIGS. 1 and 2) is threadable through leg 56 and is aligned with tab 54 The connector is made of electrically conductive material except for the insulation blocks 42 and S3 to define a first conductive path through upper body assembly 26 and lower body assembly 24, and a second conductive path through upper chuck ill.

Operation in the operation of the connector, coaxial line 11 is inserted through opening 34 in sleeve 33 such that center conductor 13 is pressed into beveled end 43 of upper chuck 41 and outer conductor 14 is pressed into split ferrule 32 Sleeve 33 is threaded into the outer sleeve 27 to compress ferrule 32 about outer conductor 14 and lock the coaxial line with the upper body.

Strip line 12 is inserted into the U-shaped bracket defined by legs 66 and 6'7 such that tab 54 slidably engages center conductor 17. Clamping screws 64 are inserted through the holes in leg 66 and strip line 12, and are then threaded into the holes in leg 67 to clamp the strip line to the lower body. Locking screw 68 is threaded downward to press block 21 against tab 54, thereby clamping the tab to center conductor 17. Clamping of tab 54 to center conductor 17 is adequate for high fre quency applications; however, a solder connection may be used for low frequency applications.

An impedance mismatch almost invariably results when connecting coaxial line 11 to strip line 12. Tuning screws 61 are adjustably positioned within cavity 49 to vary the capacitance of the cavity. Such varying of the capacitance of the cavity is commonly referred as tun ing. Since impedance is a function of capacitance, the impedance mismatch of the coaxial line and strip line is compensated by adjustment of the tuning screws.

Although two tuning screws 61 are shown opposite each other in the figures, it is to be understood that the tuning screws may be placed at positions other than 3 opposite and more than two may be employed. The number and positions of tuning screws 61 employed is dependent on the frequency of the transmitted signal, the strip line circuitry (represented by center conductor 22), and the amount of capacitance needed to be compensated.

I By varying theca'pacitance of cavity 49 to match the impedance of lines 11 and 12, a phase shift is introduced into a signal being transmitted along the over-all line.

The position of projection 30 of upper body assembly 26 is adjusted within lower body 24 to alter the axial length of cavity 49. Since the phase shift experienced by the signal is alsoa function of the physical length of the conducting path, this alteration of the length of cavity 49 effectively changes the length of the conducting path and thereby compensates for the phase shift introduced by the impedance matching. It follows that the alteration of the length of cavity 49 also compensates for phase shift in a signal introduced by the coaxial line and strip line themselves. Lock nut 46 is adjusted to lock lower body a'ssernbly 24 and upper body assembly '26 in position.

Although the invention has been described and illus- 'trated with respect to a straight connection between a coaxial line and a'strip line, it will be apparent to one skilled in this art that the connector can be modified to connect a coaxial line and a strip line at other angles, for example 90. This can be accomplished by modifying the external U-shaped bracket for clamping the strip line the connector.

It is to be understood that the above-described embodiment is illustrative of the principles of the invention and many others 7 couldbe devised without'departing from the scope of the invention.
