Definitions
- the present invention relates to the construction of an electrical connector specially adapted to effect interconnection of the conductors of a plurality of transmission lines.
- circuits exist in which a plurality of conductors must be interconnected in various more or less complex fashions.
- Typical of such circuits are so-called hybrid circuits, in which a plurality of conductors, often of transmission line form, are connected to produce a desired degree of isolation between certain of the ports to which the outer ends of the conductors are connected and to produce a desired type of power distribution between others of the ports to which others of the conductors are connected.
- hybrid circuits in which a plurality of conductors, often of transmission line form, are connected to produce a desired degree of isolation between certain of the ports to which the outer ends of the conductors are connected and to produce a desired type of power distribution between others of the ports to which others of the conductors are connected.
- the connecting means and the conductors are important factors in the overall design of a piece of equipment provided for a given purpose. Specifically, twists and bends in transmission lines are to be avoided, and the connections between the conductors of the transmission lines should be as direct as possible. The more
- hybrid circuit which presents particularly troublesome problems in these regards is that disclosed in French Patent No. 810,300 and French patent of Addition 48,362.
- This type of hybrid comprises a four-sided bridge with inputs made to opposite pairs of sides of the bridge, the outputs from the bridge being derived from diagonal connections thereacross. If, as is desirable in high frequency work, the bridge sides and the diagonal connections be formed at least in part of transmission lines, siX transmission lines must be connected to one another in a fairly complicated manner. To make these connections directly would be troublesome and time-consuming, would involve a mares nest of wiring which would greatly detract from the proper functioning of the overall circuit, and would also constitute a source of potential trouble and malfunction.
- the present invention relates to the construction and arrangement of a connector, and to the connection thereto of transmission lines, as defined in the appended claims and as described in this specification, taken together with the accompanying drawings, in which:
- FIG. 1 is a circuit diagram of a bridge type of hybrid circuit of the prior art in connection with which the connector structure of the present invention is particularly useful;
- FIG. 2 is a circuit diagram of the transmission line connections to be made in connection with the hybrid circuit of FIG. 1;
- FIG. 3 is a front plan view of a typical member from which the connectors of the present invention are constructed
- FIGS. 4 and 5 represent modifications of the member of FIG. 3 which are designed to be assembled to form one embodiment of the connector structure of the present invention
- FIG. 6 is a three-quarter perspective view, on an enlarged scale, showing the members of FIGS. 4 and 5 assembled together;
- FIG. 7 is a three-quarter perspective diagrammatic view (the insulating sheets of the connector of FIG. 6 being eliminated for illustrative purposes) showing the manner in which the structure is used to accomplish the interconnections required in FIG. 2;
- FIGS. 8 and 9 represent other modifications of the member of FIG. 3 which are designed to be assembled to form another embodiment of the present invention.
- FIG. 10 is a three-quarter perspective view on an enlarged scale showing the embodiment produced by the assembly of the members of FIGS. 8 and 9.
- the connector structure of the present invention is here specifically disclosed as accomplishing the required electrical connections for a hybrid circuit of the type generally shown in FIG. 1.
- This circuit has been selected because of the relative complexity of the transmission line interconnections required and because of the relatively large number (six) of such lines which must be interconnected. It will be understood, however, that the invention has applicability in many other specific areas.
- the hybrid circuit of FIG. 1 comprises a first pair of opposed ports 1A and 1B and a second pair of opposed ports 2A and 2B.
- the ports of each pair are designed to be isolated from one another when either one of those ports is used as an input port, the input power equally dividing between and appearing at the ports of the other pair.
- the port A is electrically connected to a pair of primary windings 4 and 6, connected in parallel, those winding-s being electromagnetically associated with secondary windings 8 and 10 respectively.
- the port 1B is electrically connected to a pair of primary windings 12 and 14 connected in parallel, those windings being electromagnetically associated with secondary windings 16 and 18 respectively.
- the secondary windings 8, 16, 10 and 18 are connected together sequentially to define the sides of a bridge circuit.
- the ports 2A and 2B are electrically connected to primary windings 20 and 22 respectively, those windings being electromagnetically associated with secondary windings 23 and 24 respectively, the winding 23 being connected diagonally across the bridge between corner points 26 and 28, and the winding 24 being connected diagonally across the bridge between corner points 30 and 32. (The designation of particular windings as primary or secondary are purely arbitrary.)
- FIG. 2 is a circuit diagram of a transmission line embodiment of the hybrid circuit generally disclosed in FIG. 1. It comprises transmission line-s A, B, C and D, corresponding respectively to the windings 16, 8, 18 and 10 of FIG. 1, and transmission lines E and F corresponding respectively to the windings 23 and 24 of the circuit of FIG. 1.
- Each of these transmission lines comprises a pair of conductors, differentiated by being termed inner and outer conductors, this terminology corresponding to the structure of a concentric transmission line.
- the conductors are identified as A and A representing the inner conductor of line A and the outer conductor of line A respectively, with the conductors of the other lines B-F being correspondingly identified. It will be noted that the following connections must be made: B; with C C with D D with A A, with B E, with B, and C B with D and A F, with B and A and F with C and D,.
- the connector structure of the present invention which will now be described, is designed to permit the eifectuation of these and comparable electrical interconnections, particularly between the conductors of transmission lines, without those disadvantages.
- the connector structure in the form here specifically disclosed, is made up of a pair of connector members generally designated 34, all of which are of similar construc tion. They comprise, as may be seen from FIG. 3, a sheet or plate 36 of appropriate insulating material having opposite side surfaces 38 on each of which a pair of conductive sections 40 are mounted. Those conductive sections 40 may be formed in any appropriate manner, as through the use of conventionel printed circuit techniques or through the afiixation to the surfaces 38 of discrete strips of conductive material.
- the conductive sections 40 on the side surface 38 not visible in FIG. 3 are preferably in registration with the conductive sections 40 on the visible side surface 38 in FIG. 3.
- the sections 40 on each side surface 38 are angularly related to one another so as to define an essentially V-shape, but with the sections 40 terminating short of the vertex of the V so as to define a non-conductive area 41 therebetween.
- the member 34A is provided with an edge notch 44 extending up into the body of the member 34A from the edge 46 toward which the vertex of the V is directed, the notch 44 extending into and substantially through the area 41.
- the member 34B is provided with an edge notch 48 which extends inwardly from the edge 50 away from which the V points, the notch 48 being in line with the vertex of the V and terminating short of the area 42.
- the members 34A and 34B are assembled in egg-crate fashion by interfitting those edge notches 44 and 48, thereby to produce the structure shown in FIG. 6.
- each conductive section 40 carried by a given member 34A or 34B will substantially meet a conductive section canried by the other member, and electrical connections between those sections can be simply effected through the use of solder.
- FIG. 7 is a diagrammatic representation of the embodiment of FIG. 6 with the insulating sheets 36 eliminated to show the nature of the electrical connections, a conductive section 40 carried by the member 34A is electrically connected to the section 40 carried by the member 34B.
- sections 40 and 40 define sections of a first conductive length
- sections 40 and 40 comprise sections of a second conductive length
- sections 40, and 40 comprise sections of a third conductive length
- sections 40 and 40 comprise sections of a fourth conductive length, each of those conductive lengths being insulated from all of the others.
- transmission lines corresponding to the lines A-F of FIG. 2 are disclosed in electrical connection, and the various conductors thereof are identified by the same reference numerals as are used in FIG. 2.
- the transmission lines A-D are connected to their appropriate conductive sections adjacent the ends of those sections, which are at the same level but which face in different directions.
- the transmission lines E and F engage the connector at different levels at the vertices of the Vs formed by each electrically connected pair of conductive sections.
- the appropriate sections are provided with apertures 42 through which the inner conductors of the appropriate transmission lines pass.
- the outer conductor of a transmission line engages that surface, of the appropriate conductive section 40 toward which the transmission line is directed, and the inner conductor of that transmission line passes through the opening 42 to the other side of the member 34, thereby not making electrical connection with the same conductive section 40 as its outer conductor part but instead making electrical connection with the conductive section 40 opposite the one to which its associated outer conductor is electrically connected.
- the actual electrical connection can be made in any appropriate manner, as through the use of solder.
- connection portions of the transmission lines E and F constitute physically diagonal connections between the Vs defined by the electrically connected conductive sections as well as defining electrically diagonal connections as indicated in FIGS. 1 and 2.
- FIGS. 8-10 A second embodiment of the present invention is disclosed in FIGS. 8-10. It, like the embodiment of FIGS. 4-6, comprises a pair of assembled sections 34, but in the embodiment of FIGS. 8-10 the sections 34A and 34B differ from the sections 34A and 3,413 in that the edge notch 44' of the member 34A is not as deep as the edge notch 44 in the member 34A, and in that the member 34B is a substantial duplicate of 34A and has its edge notch 48' extending from the edge 46 instead of from the edge 50, and to substantially the same depth as the edge notch 44' in member 34A.
- the members 34A and 34B are assembled, and as maybe seen from FIG.
- the sections 40 and 4% carried respectively by the members 34A and 34B will not form a V, as in the embodiment of FIGS. 47, but will instead constitute substantial prolongations of one another bent, however, about the vertical axis of the assembly.
- the same will be true of the other pairs of electrically connected conductive sections 40 40 40 40 and 40 40
- the lines electrically meeting conductive sections 4-0 and 40 e.g. lines C and A
- the lines meeting the conductive sections 46 and 40 e.g. lines D and B
- the lines adapted to meet the electrically connected sections near their joint e.g. lines E and F
- the connector structure is made from a plurality of identical or substantially identical elements 34, is readily assembly, and when thus assembled constitutes an efficient interconnecting device for effecting complex circuit interconnections, particularly when transmission lines are involved.
- the use of solder or other means to electrically connect the conductive sections defining each conductive length also serves to physically secure the two members 34 in assembled condition, and when diagonal electrical connections are effected, as through the use of transmission lines E and F, the soldering or the like which electrically connects such transmission lines to the appropriate conductive sections also conmeets those sections together to define the individual conductive lengths and secures the members 34 in assembled condition.
- the nature of the electrical connections produced is one which is conducive to efficient high frequency applications, and the external conductors may be connected in a simple manner, without interference, and without requiring complex pre-shaping.
- a connector comprising first, second, third and fourth conductive lengths each having A and B sections angularly disposed relative to one another about a first axis, said lengths being arranged with the A section of each length positioned opposite and spaced from the B section of another length to define four sets of opposed length sections, and insulation between the opposed length sections of each set.
