Key Words: patch-board programming system; arrays of slots; electrical connectors. This invention relates to apparatus and processes for an improved patch-board programming system and more particularly to apparatus and processes concerning holes in a patch-board panel. A patch-board, also known as a patch bay, is a device where by a plurality of plugs connected to a first plurality of circuits may selectively connect with a plurality of connectors connected to a second plurality of circuts.Patch-boards are used, for example, in telephone switching systems and electronic computers. The patch-board programming system consists of two mating panels. One is attached to the computer and the other, called the portable panel, is removable. The port-able panel has a matrix of holes in which a large number of connector plugs may be removably inserted. It is possible to program the computer by inserting the proper plugs in selected holes at a location remote from the computer. At the same time the computer may be operated with a different program arranged panel, saving costly computer time.Patch-board programming system is on another portable.This general type of further described in U.S. Patent No. 2,647,244 to Dewey and Zatsky, issued 7.28. 1953. The problem of accurate placement of many contacts at a reasonable cost has been solved in unshielded patch-board programming systems. Such contacts, consisting of metal springs or prongs, may be positioned in the form of a matrix and placed in a rigid, molded plastic frame.However, the problem is more difficult in patch-boards for use with shielded coaxial cable. Such cable consists of an inner conductor, an insulator, and an outer conductor. The termination for such cable consists of a conductive connector, insulation around the conductor, and the patch-board panel, which is conductive. It has not been possible, heretofore, to maze a patch-board for use with coaxial cable which possesses the required accuracy at a reasonable cost. One known ;method is to drill individual round holes in a conductive metal panel in a sequence to obtain a matrix of a thousand or more holes. This process is necessarily slow and relatively costly even with programmed machine tools. The connectors positioned in the holes consist of a metal prong surrounded by a round shank of plastic insulation. Due to their round shape, they tend to rotate and become in-correctly aligned Another known patch-board is made up of a large number of individual cells. Each cell consists of a spring con-tact surrounded by rectangular plastic insulation. The cells are fitted into openings formed by interlocking metal grids, the interlocking being formed like an "egg carton." As the cells and metal grid members are assembled, they may build up tolerance variations. For example, if more of the cells in the first part of one row are oversized and the cells later in the row undersized, the overall dimension of the row may be correct and yet contacts near the center may be out of position. This assembly, due to the need for hand fabrication and constant tolerance checking, is relatively expensive to manufacture. The present invention overcomes the difficulties of the prior devices by providing a highly accurate and relatively inexpensive patch-board panel. The panel is machined of metal, preferably on a high-accuracy milling machine. The machining forms a set of parallel grooves having raised ribs running one way on the first surface of the panel and similar parallel grooves running at an angle to the first set and cut into the opposite surface. Preferably the grooves in one surface are perpendicular to the grooves in the other surface. The total depth of the crossing or perpendicular grooves is greater than the thickness of the panel. Accordingly, the crossed grooves form four-sided polygonal holes. A plurality of conductive spring fingers each surrounded by insulating material, preferably plastic insulation, are force-fitted into the polygonal holes. These spring fingers form a set of non-removable shielded contacts on the fixed panel. They cooperate with a set of removable coaxial plugs inserted into a mating, portable panel to complete a plurality of circuits of the patch-board programming system. It is therefore a principal objective of the present invention to provide a relatively inexpensive patch-board system in which the contacts are very accurately aligned and positioned. It is a further objective to shield each individual connector within the system so that the connectors may be used with coaxial cable. It is a further objective to provide correct orientation for the connectors so that they make good electrical contact with their mating plugs. It is an additional object to provide an improved method for the manufacture of patch-boards. Other objects and features will become apparent from the description taken in conjunction with the drawings, in which: FIG. 1 is a pictorial perspective partly cut-away view of a portion of the patch-board system; FIG. 2 is a side cross-sectional view of two circuits of the system of FIG. 1 taken along lines 2-2 with two patch plugs and two contacts making electrical connection; FIG. 3 is a top cross-sectional view taken along lines 3-3 of FIG. 2 with parts shown in elevation; FIG. 4 is a plan view of a portion of the rear of the fixed panel; FIG. 5 is a perspective view of a protion of the fixed panel; FIG. 6 is a perspective exploded view showing how a conductive spring contact mounts in an insulating block; FIG. 7 is a top cross-sectional view taken along lines 7-7 of FIG. 8 showing the spring contact mounted in an insulating block; FIG. 8 is a side cross-sectional view taken along lines 8-8 of FIG. 7; FIG. 9 is a back cross-sectional view taken along lines 9-9 of FIG. 7. FIGS. 1-5 show an electrically conductive fixed rear panel 10 with a plurality of polygonal rectangular holes 11. Holes 11 are produced by a novel and inexpensive process. Prior to machining, panel 10 may be a flat metal plate having flat surfaces 12 and 15. A first surface 12 machined or milled, for example, to a first depth 13 producing a first set of parallel slots 14 having upstanding ribs between the slots. The depth and position of the slots may be machined, or otherwise fabricated, to an accuracy of 0.005 inch using, for example, conventional milling machines. Opposing surface 15 is likewise machined to a second depth 16 producing a second set of parallel slots 17 and ribs which are, preferably, perpendicular to the slots 14 and ribs of the first surface.Holes 11 are produced by the sum of depths 13 and 16 being greater than the distances of depths 13 and between surfaces 12 and 15Preferably each of the slots exceeds in depth one-half the thickness of the panel 10. Alternatively, one set of slots on one surface may have greater depth than the other set, as long as the total depth of the two cuts exceeds the thickness of the plate so as to produce polygonal holes 11 at the intersections of slots 14 and 17. Slots within a particular set 14 or 17 are preferably parallel to each other and of uniform cross-sectio..Holes 11 are rectangular because slot sets 14 and 17 are perpendicular to each other.If desired some other quadrilateral shape of suitable angle between slot sets 14 and 17 may be chosen. The construction of the individual connectors, and their insulation, is shown in FIGS. 6-9. As is shown in FIG. 6, insulating block 18 is made up of two identical and complementary sections 18a and 18b having slots 19a and 19b, respectively. The connector spring finger 20 is of a conductive spring material; for example, beryllium copper.Spring finger 20 includes a bend 28 and a detent 29 to give a press force and to make contact with its mating prong. Spring finger 20 also includes protruding portions 31 and 32 provided for interlocking with the recessed shoulders of corresponding portions 33a and 33b of the block 18. In the assembly of the spring finger and its insulation, the electrical contact of spring finger 20 is first fitted into one slot, say 19b.Then section 18a is positioned next to section 18b and spring finger 20 is positioned in slot 19a. Alternatively, block 18 may be molded of plastic in one piece with the spring finger 20 molded in place,or molded in one piece, and then the spring finger 20 inserted into its flat opening. Preferably block 18 has a cross-section slightly larger than holes 11 and is fitted into holes 11 from the back of panel 10. The press fitting extrudes or distorts the plastic of block 18 so that the bock is firmly held in place.Block 18 may, alternatively,be held in place by other methods,such as adhesive bonding. Steps 21a and 21b on block 18 prevent it from being pulled forwardly made of any insulating from panel 10. Block i8 may be made of any insulating material, preferably a plastic such as a polymer of caprolactam such as nylon capable of being press fitted into holes 11 and held firmly in place by the crossed ribs of the panel around those holes. Economy of design also suggests making block 18 of two molded and identical half sections 18a and 18b, each having faces 51 for mutual juxtaposed mating upon assembiling the pair of sections together on spring finger 20.The press fit of this assembly in hole 11 maintains the sections in interlocking relation. FIGS.2 and 3 show only two blocks 18 and fingers 20 in place;However,there will usually be a block 18 amd finger 20 for each of the holes 11.The rear end of spring finger 20 extends beyond panel 10 and is adapted to be connected to a mating connector (not shown). A suitable mating connector may be in shape of a partial channel member which is forced over the rear end of spring finger 20. FIG. 1 shows a portable second panel 22 which has holes 23 corresponding to holes 11 and is removably positioned near panel 10.Some of the holes23 are removably filled with coaxial jack plugs 24.Each of the plugs 24 has an outer shell connected to the outer conductor of a coaxial cable (not shown). The conductive prong 26 of plug 24 is connected to the inner conductors of the coaxial cable. A suitable coaxial jack plug is described in U.S. Patent 2,983,895, to Pasik, issued May 9,1961. Preferably, panel 22 is conductive so that the surface defining hole 23 makes contact with outer conductive shell 25 of plug 24. Panel 22, in that case would be a grounded plate and would act to ground the outer conductive shell 25 of the plug 24. Panel 22 may have plugs 24 already inserted into its holes 23. Therefore, when panel 22 is positioned near panel 10 it is offset downwardly and then slid up,allowing prongs 26 to contact spring fingers slid up, allowing prongs 26 to contact spring fingers 20. Blocks 18 properly orient spring fingers 20 in order to make this contact. Intermediate metal shield 30 may be used. Preteranty the shield 30 is in the form of open-ended joined boxes made from interleaved sheets as in an "egg crate".Shield 30 is grounded to panel 10.Shield 30 is positioned around every prong 26 and spring finger 20 to shield each circuit from the other. The shield 30 may be notched to fit into the milled slots 17. An outer shield(not shown) similar to shield 30 may be used to surround the rear end of plugs 18 behind fixed panel 10. Such an outer shield would also be grounded to panel 10 and provide for individual shielding of the ends of blocks 18.
