Definitions
- This invention relates to electrical connectors and is particularly concerned with connectors for use on coaxial cables commonly used for the transmission of radio frequencies.
- an electrical connector for use in a coaxial transmission line should present an impedance as close as possi-ble to the characteristic impedance of the coaxial line in order to avoid reilections.
- an electrical coaxial connector should also consist of a minimum number of parts, be easily assembled, and have characteristics of construction which minimize movements of the connector components even during varying mechanical stresses on the connector or the cable connected thereby.
- the electrical connector of the present invention provides an element of independent design freedom for equalizing or compensating impedance characteristics within the connector at the dimensional transition from the line to the main body of the connector. This marks the diametrical enlargement of the solid insulation within the outer cable system conductor elements where the line dielectric abuts the connector dielectric.
- the element comprises a counterbore in the connector dielectric larger than the outer diameter of the line dielectric to provide in combination therewith an annular air gap.
- the radial and axial dimensions of the air gap may be selected by the design engineer independently of other parameters to achieve the desired operation of the transmission line systern at a desired frequency or over an extremely broad range.
- Connectors of the present invention characteristically employ resilient solid dielectric components radially interiitted with matting metallic conductor elements to prevent axial displacement in any direction. Such dielectric components transiently deform in the manufacturing or assembly operation during implacement and lock permanently in axial design position against the stresses of practical use.
- resilient solid dielectric elements may be radially intertted in axially locked position with either or both the central conductor element and the outer annular conductor shield. Longitudinal positional stability is especially important in avoiding variable air gaps under application conditions.
- An object of the invention is to provide a coaxial connector presenting constant impedance to the line over a desired frequency band through the use of an independently designed impedance section at the abutment of the cable dielectric with the connector dielectric.
- Still another object of the present invention is to provide an electrical connector for coaxial cables in which the electrical characteristics are stabilized because the mechanical components of the connector are securely interconnected to prevent relative movements and are so dimensioned as to substantially eliminate air gaps between abutting dielectric members.
- Yet another object of the present invention is to provide an electrical connector with improved coaxial cable retention characteristics.
- a further object of the instant invention is to provide a coaxial connector which has a small number of parts to he assembled, thereby facilitating assembly as well as assuring uniformity in the electrical characteristics of the connector.
- FIGURE 1 is a central cross-sectional View of the connector jack subassembly prior to assembly
- FIGURE 2 is a partially cross-sectional view of a mating plug prior to assembly with the connector jack of FIGURE 1;
- FIGURE 3 is an enlarged view partly in cross-sectional view of the assembled electrical coaxial connector
- FIGURE 4 is an enlarged sectional view of a portion of FIGURE 1 showing a part of the dielectric insert including the novel retention means.
- the main jack assembly 10 may be clearly seen in FIG- URE 1 where metallic outer body member 12 consists of rearwardly extending ferrule 13 which is provided with grooves 14 in order to better grip the conductive shield of the coaxial cable when nally assembled. Instead of employing grooves, the ferrule may be externally knurled.
- the forward extending contact portion 15 includes locking stubs 16 which are utilized during the nal connector engagement. Cylindrical opening 17 extends through the ferrule portion 13 to a counterbore 18 whose diameter is increased at shoulders 19, the inclined wall 20, and beveled end 21 in order to provide for easy connection with the plug assembly.
- a cylindrical dielectric sleeve 22 is dimensioned to t tightly within counter-bore 18 and is secured by lock washer 23 which is press fitted in shoulder 19.
- Insulating insert 22 is provided with a central bore 25 which extends from the compensating air gap counterbore 24 through the forward extending mating portion 26 and which includes the locking shoulder extension 27.
- Counterbore 24 is not completely filled with coaxial cable dielectric in the .nal assembly, as subsequently explained, which provides impedance compensation for the over-al1 connector.
- Locking shoulder 27 may be seen with greater clarity in an enlarged sectional view in FIGURE 4, where a portion of the annular edge 28a of chamfered end 28 is shown with end 29 which is perpendicular to the central bore 25.
- FIGURE l Shown in FIGURE l as tightly secured in insulating insert 22 is the'female inner contact 30, which for the sake of clarity in the illustration is not shown attached to the central conductor of a coaxial cable.
- Contact 30 may be seen to include a conductor-receiving bore 31 and solder port 32 through which solder may be applied to secure the central conductor of a coaxial cable before final assembly of the connector.
- Shown in an interlocking relationship with locking shoulder extension 27 is an annular locking groove 33 in inner contact 30.
- FIGURE 4 shows in detail how perpendicular edges 34 and 35 of the contact 3()y fit closely with the respective ends of the locking shoulder extension 27.
- the female contact portion 36 in FIGURE l is designed to receive a male contact portion in mating relationship and may also be seen to taper slightly toward the forward end of the contact. This taper enables the elongated contact 3.0 to be easily inserted into the central bore and to ride or clim-b up cham-fer 28 during insertion.
- Dielectric 22 is commonly made of a deformable plastic such as Teflon, or a polypropylene composition available as Avisun grade 1044, which enables the rigid contact pin 30 to deform locking shoulder extension 27 during insertion. The pin is pushed through the central bore until the -forward perpendicular edge of the annular locking groove 33 snaps into place over the perpendicular end 29 of the locking shoulder extension 27.
- the rearward edge 34 of the elongated contact pin tightly tits against the base of chamfered end 28, and therefore it may be seen that the elongated contact pin 30 is locked into position in the insulating insert 22.
- prior art devices provided means only to lock a contact pin in one direction
- the present invention may be seen to provide locking action in both forward and backward directions.
- the locking edge 29 of insert 22 is utilized to prevent the contact from being withdrawn from the connector Ibecause of forces applied upon the coaxial cable.
- This longitudinal positioning of the central contact by intertted radial variations is quite important in reducing relative movement between the various parts of the connector and thereby substantially eliminating changes in V.S.W.R. characteristics.
- plug assembly 11 is shown in cross-section with the contact pin position, without the coaxial cable for simplicity of description.
- Rotatable outer mating cover 37 may be seen to enclose the metallic main plug body 38, which is held in rotatable relationship with mating cover 37 by means of restraining sleeve 39 which is forced into a suitable groove 40 in the main housing 37.
- Sleeve 39 fits loosely around main plug body 38 thus allowing the outer mating cover 37 to be easily rotated during finel assembly.
- Main plug body 38 is further supported by flexible gasket 41 which fits in slidable relationship with the outer mating cover 37.
- Spring washer 42 provides a Ibiasing force to compress gasket 41 to firmly seat main plug body 38 when the connector is nally assembled.
- the main plug 'body 38 consists of an intermediate coupling portion 43 which joins flexible outer contact member 44 with rearwardly extending ferrule portion 45 to form a unitary body construction.
- Ferrule portion 45 may be seen to be provided with grooves or notches 46 which provide a strong gripping force to the metallic braid of the coaxial cable when the connector is fully assembled.
- Main plug body 38 also has a cylindrical opening 47 through ⁇ ferrule 45 to a counterbore 48 which extends the length of the flexible outer contact 44.
- Contact 44 is constructed with an outward flaring annular contact 49 to provide a good electrical contact when the plug assembly is mated with jack 10.
- Contact 44 may be preformed and machine inserted in lbody 43, soldered therein around the outer juncture, and the assembly plated with a suitable covering. Then insert 51 may be pressed into position. The indented retention means 50 of the flexible outer contact is used to secure the dielectric insert 51 at the annular rounded groove 62, thus providing permanent positioning of the insert in the plug body.
- Insulating insert 51 utilizes several features of the utmost importance in providing satisfactory electrical connector characteristics.
- impedance compensating air gap 52 consists of a counterbore whose depth and diameter are determined by calculation based upon the amount of impedance compensation desired in order to obtain flat line voltage conditions.
- the ⁇ forward end 53 of the insulating insert 51 extends axially beyond the end of the aring annular contact 49. This extension has been found to provide markedly improved results in the V.S.W.R. of the assembled electrical coaxial connector, as it enables the insulating insert 51 to abut firmly under biasing action of spring member 42 with its mating component insert 22 upon assembly, thus preventing variable air gaps from forming in the assembled connector.
- the forward end 53 of insert 51 denes a counterbore with a depth equal, within manufacturing tolerances, to the length of the forward extending mating portion 26 of the dielectric insert 22 of the jack assembly shown in FIGURE 1.
- the ja-ck insulating insert 22 tits into the counterbore formed by the forward end 53 of insert 51 until the inserts firmly abut, as subsequently to be shown.
- the locking shoulder extension 55 which projects from central bore 54 and includes a chamfered end 56.
- elongated contact pin 57 consisting of a forwardly extending mating portion 5S, annular locking groove 59', and central conductor -connection bore 60, is inserted through the cylindrical opening 47 into the central bore 54, the contact meets chamfered edge 56.
- the forward portion 58 of contact pin 57 is provided with a bevel 61 which rides inside chamfer 56, thereby temporarily deforming the flexible insulating material of the dielectric insert 51.
- Connecting bore 611 is provided in combination with port 63 whereby solder may be inserted to attach the central conductor of a coaxial cable before inserting the elongated contact 57 into the plug 11.
- FIGURE 3 shows the fully assembled electrical coaxial connector assembly, the same numbers have been used for like components previously described.
- the coaxial cable 64 is prepared in a manner known in the prior art by stripping back the outer insulating cover 65, the metallic braid 66, and the dielectric 67 in a stepped manner to expose central conductor 68.
- both ends 64 and 69 of the coaxial cable are thus -prepared and lare soldered to elongated inner contacts 30 and 57, respectively.
- These completed subassemblies are then inserted into the ferrule portions of the plug 11 and the jack 10, with the braid 66 being slightly flared in order that the rearwardly extending ferrules 13 and 45 may be slipped under the braid.
- the novel contact locking means of the instant invention provides a connector apparatus which may be assembled in swift operation, ⁇ but which provides precise contact positioning and retention in two directions.
- the central bore in the integral section of the dielectric insert has a radial variation in diameter which interts with a corresponding variation in diameter of the central connector to lock the parts against relative axial displacement in either direction.
- an electrical connector embodying the invention has the advantage of providing low V.S.W.R. characteristics, while at the same time maintaining these characteristics in a nonvarying manner even in the presence of outside forces on the cable or ambient temperature changes. Further, these uniform electrical characteristics are obtained by a connector of improved mechanical strength, but which still allows the prepared end of the coaxial cable to be quickly and easily inserted in the basic connector subassembly.
- the electrical connector of the instant invention has the additional advantage in consisting of relatively few and simple components which permit close mechanical tolerances to be maintained during manufacture and assembly of the connector.
- An electrical connector for a radio frequency coaxial transmission line having an inner conductor encircled by an annular insulating layer and a conductive shield comprising:
- a metallic body member having a forward contact extension and a rearwardly extending ferrule portion, said body having a cylindrical opening extending through said ferrule portion to a larger diameter cylindrical opening coaxial therewith and extending through said contact extension,
- an insulating insert which its into said larger diameter opening, said insert having a central opening throughout its length with an annular locking shoulder eX- tension radially extending within the central opening of the insert at a point intermediate the ends thereof, said insert also having an impedance compensating counterbore in the rearward end thereof, the diameter of said impedance compensating counterbore being greater than the diameter of the cylindrical opening through said ferrule portion, and
- an elongated inner contact joinable with the inner conductor of a coaxial transmission line said contact being shaped for insertion through said ferrule portion into the central opening of said insert and having an annularly grooved solid portion, said groove being dimensioned to tightly interiit with said shoulder eX- tension to resist axial movement of said inner contact with respect to said insert thereby reducing electrical retiections and stabilizing the electrical characteristics of the connector, the annular insulating layer of the coaxial transmission line extending into said counterbore to the rearward end of said inner contact upon insertion of said inner contact through said ferrule portion into said insert.
