"Electrical conductor arrangement and process for their manufacture"

The priority of filing in the UK on November 15, 1961 No. 4o 858/61 has been used.

The invention "relates to electrical arrangements Devices. There are ladder assemblies "known in electrical Devices find application and are referred to as printed circuit boards. This well-known technique exhibits but various disadvantages. The printed circuits are often produced on plates, but not arbitrarily can be enlarged, otherwise the plates Too easy to warp or bend, which increases the risk of a short circuit between the connecting wires the components or between the individual circuit boards, provided they are printed on both sides, results. Besides that are the cable runs of the printed circuit boards Can only be used for a limited current density and its thin copper cladding can easily be damaged by mechanical Influences are destroyed.

The invention has the object of avoiding the disadvantages of the known circuit technology. According to the invention this is achieved in that a conductor arrangement contains two or more conductors made of a material with good electrical conductivity, which, with the exception of the connection ends, are completely in the insulating material are included and of which;} edea? line arrangement from a specific, previously produced line pattern

■ exists. A ladder arrangement preferably takes the form of a strip, the lines of which are parallel to the length of the strip and the ends of the webs of the lines or the conductor strips protruding from the insulating material are on two opposite sides of the strip led out.

According to an embodiment according to the invention, each line run or each conductor strip and the parts of the to run these associated webs within the insulating material in one plane.

"According to a further embodiment of the invention several conductor strips, each of which has a central conductor strip and webs belonging to this, next to one another arranged in parallel planes which are separated from each other by layers of insulating material. The center conductor strips that are in run in different levels, are staggered in a transverse direction. The center conductor strips in one The plane and its associated webs extending on both sides lie in two mutually different but parallel webs There are planes to each other that are created by angling the webs.

k According to a further embodiment of the invention are webs belonging to a central conductor strip before being inserted into holes in a plate on a common side angled and are angled in opposite directions after insertion. Those belonging to a central conductor strip Bars are on one side of a sheet of insulating material and the median strip itself is on the other side Insulating plate.

is punched, whereby the parts remaining in the band result in a grid-like or rust-like pattern, which is composed of one or more central conductor strips running in the punching direction and many connecting webs lying transversely to the punching direction and with delimiting strips that enclose them. The tape punched out in this way is inserted into a complete or subsequent cut in which individual stamps are arranged, which, depending on the required circuit, separate the grid-like pattern so that only the parts of the cable runs required for the circuit remain. These cable runs or conductor strips punched out in this way are covered on one side, covering the central conductor strip in the longitudinal direction, with an insulating film and the continuous conductor runs prepared in this way are separated into certain lengths. Several, for example four, cable runs separated into certain lengths are stacked on top of one another, depending on the required circuit, held in the correct position in a device and in this position encapsulated with insulating material in their middle part. After the stacked layers have been overmolded, the delimitation strips of all layers that have held the individual cable runs up to this point in time are punched out. The ends of the webs protruding from the insulation package on two sides are shortened to two different lengths. The webs located on a central conductor strip are bent at right angles and at a certain distance from the central conductor in a common direction, inserted through corresponding holes in an insulating plate and bent on the opposite side of the insulating plate in the opposite direction. The fixed to an insulating plate as conductor strips, except for the E located on two sides of a _{n e} n of the webs, are injected into insulating material or poured. The punched-out cable runs are angled around a strip of insulating material that covers the central conductor strip. Two or more cable runs around the insulating strip are pushed into one another laterally, with the • insulating strip providing electrical insulation between the

individual lines. The individual so «into one another pushed cable runs are in their middle part in Insulating material injected or poured in. The conductor arrangement injected into insulating material, in which the Insulating material protruding ends of the webs are arranged so that seen in the direction of the broad side no two ends are in a row, is inserted into a two-part tool, in which in the upper part recesses for receiving the web ends are provided and when the two tool halves move together under pressure, the protruding The ends of the webs are brought into a row by bending, and the cavities of the tool and between the insulating layers filled with an insulating material inside the embossing tool / tool. Between two conductor arrangements or structural units components are arranged by mechanical and / or automatic wiring with the connection ends of the structural units be wired. The wiring makes the individual units both mechanical and electrical connected and held. The wiring is done by soldering or welding, as well as by mechanical winding connections manufactured.

Block strips 11. This strip 11 has assumed the shape of a grate by punching elongated holes 12, which is formed by the remaining parts, namely the central web 13, the connecting webs 14 and the lateral webs 15, which simultaneously form the boundary on both outer edges . In the line network of the ladder arrangement shaped in this way, the individual conductors or remaining webs are approximately 0.05 to 0.1 ^w wide. D. The connecting webs 14 and the lateral webs 15 are of the same width as the punched holes 12, which determine the minimum distance in the finished arrangement between the individual webs. This distance also allows a favorable combination of the adjacent webs of further line guides by methods known per se. In all of the arrangements that are described, a constant distance of 0.1 "between the individual centers of the webs is assumed; for example, the webs 14 of the Streifra 11 are o, o5 ^M wide and the holes 12 lying between these webs 14 are from same width.

The punched-out strip 11 is identical in its outer appearance Dimension of the unprocessed strip 1o.

The next operation is to process the strip 11 into the final strip 16 in which already marked the pattern of required cable runs and in this only the webs remain, which are necessary for the required conductor arrangement. The work process to achieve the shape of the strip 16 is shown in Fig. 1 in sequential Sections shown »by the fact that the strip 11 resulting from the strip 1o through a Tool slides through, which has a punch 17. The three punches 18, 19 and 2o are arranged so that depending on the required line routing in the final form 16 β * the punch 19 and 2o for separating the not The webs 14 required are used and the punch 18 is used to separate the central strip 13 between the two lateral arms

is used in the designated places. Since for a certain circuit the individual webs are separated out or remain aligned for the circuit, the tool provides that the individual stamps may be drawn by hand, ie automatically controlled according to a specific plan or according to a card system so that, in the end, only the webs and strips that are required for the circuit remain in the shape of the strip 16. This is to be understood in such a way that the effort of an automatic setting is not worthwhile for small quantities or for a one-time application, so that the possibility exists that the individual punches are drawn by hand according to a certain plan. Is *

however, the number of circuits to be produced is larger, the control is carried out automatically, e.g. by a mechanism operated synchronously with the continuous strip 11, which according to a certain program on a magnetic tape or through. Punch card control expires and the individual stamps at the places where they are not needed, automatically pulls or at the places where they are used Separating out webs or for separating the median strip are required, reintroduces them into the tool.

Of course, the shape of the strip 16 cannot be produced from the strip 1 o via the shape of the strip 11 using a subsequent tool as described, but rather ( it is also possible to punch the shape of the strip 16 directly from the bare strip 1 o , either in a single work step when using a complete cut, or when repeating work steps using tools or stamps from simpler Pom. But the use of a prefabricated strip 11 enables a smooth workflow, especially for the various ladder arrangements to be made, which is effected by simple tools that are versatile can be used or can be used.

The shape of the strip 16, which comes out of the tool after the described operation, glidsdert

into a center conductor strip piece 21 that has been created by severing the central strip 13 at various points through the punch 18 and from that central conductor strip piece 21 outgoing webs 22, which form the connection between the central conductor strip section 21 and the delimitation strips 15 on "both sides. The delimitation strips 15 remain on both sides on the shape of the strip 16 and are used to separate the remaining parts of the ladder arrangement to be fixed and kept at a certain distance from each other for further work steps. In one Intermediate operation, the strip 16 is tinned in its previously created form.

Pig. 2 shows a section from the shape of the strip 16, on which an insulation layer 23 of o, o1 "thickness in the longitudinal direction of the strip 16 lying centrally and following the continuous strip 16 is applied.

The entire conductor arrangement represents a multilayer arrangement, with each embodiment within one layer being able to be different depending on the required circuit d, as will be described in more detail later. It is preferable to process the conductor shapes of the strip 16 for the individual layers in a single operation and then cut them to the required lengths. This is done by adding the insulation layer 23 by f apart separation of Porm of the strip 16 in different lengths from which the individual plies or layers are composed later, for example along the line 24 in Pig. 2. Thereafter, the individual layers are stacked to a Porm a widely lameliierten stack in which the stalled strips and webs, the circuit to the -Nmö ^ * igiw concerned are required, are included. In order to maintain a constant distance between the individual webs, the remaining web pattern is arranged within the stack in such a way that two webs in adjacent layers of the arrangement never lie directly on top of one another, but are one behind the other within the stack

and stacked on top of each other. Between the individual ladder arrangements the insulating layers 21 are provided in each case within the stack.

Pig. 3 shows such a stack of, for example, four superimposed cut pieces of the strip 16 · In this arrangement, the individual webs take up a certain amount of space, so that in the individual horizontal ones stacked strip pieces i6 in the vertical Direction but only one footbridge comes to rest.

The boundary strip 15 of the ladder shape of the strip 16 are corresponds at the following operation by separating ä

When the boundary strips 15 are cut off on both sides, ends of different lengths remain the strips 22 protruding from both sides of the insulating strip stand.

the strip becomes a much larger number of layers but too thick in this embodiment.

Pig. For example, Figure 5 shows an embodiment shown in section a ladder arrangement in which more than four layers are stacked on top of each other and combined to form a structural unit. the in Pig. The embodiment of a conductor arrangement shown in FIG. 5 has ten cable runs arranged independently of one another on. These cable runs 3o and their associated cable runs 31 are combined to form a stack in the same way as for the embodiment of a stack according to Pig.3 has been described. With the exception that the insulating layers 32 are kept somewhat narrower, and only cover a small part in the middle of the cable runs 3o, which is completely sufficient for isolation. After the individual layers of the cable runs 3o including the associated cables 31 and the insulation layer 32 are stacked one on top of the other, they are along the line of all line runs 3o held, on both sides of the webs or cable runs, the boundary webs removed and the cable runs 31 in the Pike angle bent to both sides, depending on what is required Circuit so that their bent ends come to rest along the long side of the finished stack and the Form the outer edges of the stack. An insulating layer 33 is applied to these bent ends from both sides and so that this arrangement is embedded in plastic. This arrangement is favorable for various embodiments, for but other embodiments can be used to a limited extent. The in Pig. 5 The arrangement described can, for example, be used as a structural unit for connecting two or more further structural units can be used within a device or a complete arrangement.

In the embodiments that have been described so far, the individual cable runs of the various layers are within of the stack isolated from each other. For example, the following layers are only separated from the previous one by a thin layer of

-11- "90982A / 0739 BAD orig / nal

Isolation material separated. So can be with this execution shape between the individual cable runs is undesirable Build capacities. For this reason, it is desirable when encapsulated by injection molding Arrangement, the greatest possible distribution of the metallic cable runs within the insulating material is achieved

FIGS. 6a and 6b show two ways in which this can be achieved for the embodiments described in FIGS. In FIG. 6a, for example, the four line runs are staggered in depth and length, namely one after the other, so that a structure with low capacitance is created. The line runs staggered one after the other in depth are denoted by 35 ä , the associated line runs lying in length with 36. This can be done by different arrangements of different layers stacked one on top of the other in depth, which contain cut-outs on the left and right, which are carried out in separate operations are made; when using a single ladder shape with web parts that are longer on one side than on the other, and are used on envelope within the stacked layers; or when using a single symmetrical line shape that is staggered within the stack.

6b shows another embodiment in which the individual ( line runs 35 are staggered in depth or set on gaps in alternating sequence within the stack. This arrangement results in two possibilities. In the first possibility, a common line run bo is formed that it has web parts of the same length on both sides, both of which are as long as the longest web 36 in the / finished stack common length shortened

ISE / Reg, 2647-. 12-

correct position of the cable runs within the injection is also achieved when one or more of the layers are used on envelope.

FIG. 7 shows one way by which that described in Mg Arrangement can be supported. Pig. 7 shows a punched-out block strip 4o from which a grid-like Pattern was punched out, with the outer delimitation strips 41 and longitudinally extending cable runs or webs 42 and transversely arranged webs 43, each between the delimitation strips 41 on one side, the individual longitudinal strips 42 and the delimitation strips 41 on the other side extend and the 'Connect individual strips together.

With careful elaboration of the for that described in Pig, .1 A punching technique chosen as an example can be one of the line eyes 42 running in the longitudinal direction of the strip be used, which in turn is selected by the appropriate Cable runs 43 are connected to the delimitation strips 41. All other parts that are in the circuit in question not needed ^ are punched out of the strip, leaving only the parts needed for the circuit the cable run. Such a line shape shows lig. 7b. This method offers greater possibilities far Further processing of layers arranged one above the other and staggered, as shown in fig. 6 are shown} because this makes the individual Conductor shapes can be processed by programmed punching on a common block strip. Additionally there is still the possibility for this arrangement that can be used well in various embodiments that there are two or more continuous cable runs in the longitudinal direction of the finished unit! ao is e.g. Pig, 7 # c by punching out the unnecessary file, as in fig, 7a and 7b described »achieved that two in the longitudinal direction Leituage running in the middle of the strip * Uge 44 and 45 are found, the ones lying across from »Baad Web 43 on both sides bu dem! »Gre & sttmgsstrtifea 41 au

are connected. The "two boundary strips 41 are after the injection of the whole layer in one operation or the layers are cut off in plastic so that the two cable runs 44 and 45 with their associated webs which are held by the insulating material, completely independent are from each other. The two lines 44 and 45 within the same layer can be combined to a structural unit, i.e. when stacking several layers on top of each other depending on the specified circuit by the the protruding ends of the unit are connected to one another.

The designs, which are simply arranged in terms of position, such as in Pig. 6, although they are easy to manufacture, by repeating the operations, represent a relative one Waste of material. Both in Pig. 6 are the dimensions of the insulating material used unnecessarily high, because at some point across the plane through the arrangement only a single continuous Line is located at each layer.

Pig. 8 shows a further embodiment, the construction of which can be carried out in a more material-saving manner and which leads to a more compact unit, but at the expense of a somewhat more difficult manufacturing method. Manufacturing this arrangement begins by processing a series of ladder shapes in the manner shown and described is in Fig. 1, with the exception that the webs 5o, the respective central line 51 with the delimitation webs connects on both sides, quite a bit longer than in the example of FIG. 1 shown. After editing in this way, the individual cable runs angled within a © »ageawea» embossing process, like this is shown in Fig. 8a. In this embodiment, the two webs 5o are located on both sides of the Center conductors run out, in planes lying parallel to each other, between their planes in another one above

Middle fallopian tube piece 51 is arranged. The "on both sides." Extending conductor pieces 5o are connected to the central guide piece 51 via bends.

It is a basic requirement for the construction of the arrangement, that not two webs protrude on the same side of the structural unit, those in the same transverse plane lie. It should be understood that, for example, four of the conductor shapes 54, each of which is identical to that in Pig. 8a ladder shape shown, can be arranged lying in the same plane with all their central webs 51, and all web parts 5o of one side of the center conductor 51 can lie in a second common plane. The individual cranked Bridge parts 5o, seen in the tie, overlap one another. All the delimitation webs 52 of the web parts 5o on the one hand Pages are in turn on a common further level. This conductor arrangement can be clamped in this state are held on both sides on the webs 5o approximately on the dashed lines 56, while the between These lines 56 are arranged with insulating material 55 "as in Pig. 8b, is overmolded. At the end will be all of the web parts 5o protruding from the overmolded part are cut off at the line 56, so that the delimiting webs 52 are removed by this operation and only the ends of the webs 5o on both of the overmolded part Sides protrude. These web ends are divided into two or more different ones depending on their task within a circuit Shortened lengths.

The one in Pig. The assembly shown in Fig. 8 contains a conductor arrangement which is similar to that shown in Pig. 6 is identical to the conductor arrangement shown, only it has the advantage over this that it is made smaller and that the protruding from the plastic part Web ends 5o are arranged in a row on a common plane.

In Pig. 9 is another possible method of manufacture shown a conductor arrangement according to the invention. The pre-made The part from which the ladder shape 57 was created is produced in approximately the same way as that according to Pig. 1 "described conductor shape. The conductor shape 57" consists from a central conductor strip 58, from which long web parts 59 lead away on both sides. Me delimitation bars 15 those in Pig. 1 do not apply to the shape of the ladder 57 · The shape of the ladder 57 is made from a normal block strip, by punching out the parts of the block strip lying between the webs 59 and by separating the central guide strip in the desired places. Then the two web parts 59, which are located on both sides of the central I guide strip 58, as in Pig. 9b shown twice cranked. In contrast to the aforementioned designs of conductor shapes, the conductor shape 57 consists of a Number of parts that are not connected to one another, each of which has only a single long central conductor strip 58 underlying.

The conductor arrangement according to 3Pig. 9 is made in such a way that the individual conductors that are introduced into the insulating material plate in the insulating material plate without further encapsulation are held, so that it is sufficient in this form to add this arrangement to further operations or to use them in this way as a ladder arrangement for experimental purposes. in the laboratory. The overeaten land The ends of the webs 59 protruding from the insulating material plate 60 are of course shortened to a certain desired length.

In Pig. 1o shows a step within a manufacturing process that leads to this possibility. In this The work step is the ladder shape 57, which is identical to the ladder shape shown in Pig »9, through one already described Work technique edited. A strip 63 of insulating material is placed over the center conductor strip 58 so that that the two lateral ends of the strip 63 protrude over the central conductor 58. Me from center conductor 58 on the side webs 59 pointing away are then, as shown in Fig. 1o, angled around the strip 63 so that on the lower side of the strip 63 of the center conductor 58 and on the two side parts of the strip 63 in each case the Web 59 come to rest. The upper side of the strip 63 is lateral neither from the conductor part 58 nor from the two Se Ladder webs 59 touched. A variety of such conductor shapes can be nested in a side-by-side arrangement so that their laterally extending webs 59 cross one another.

Pig. 11 shows one possible embodiment of the one just described Workflow. The ladder shape is made from a single continuous block strip 65 <> FIG. 1 shows the simple case of a conductor arrangement which consists of only two conductor shapes. The punched-out strip 65 has two central conductors 66 running in the punching direction, of which webs 67 each point towards the outside lead away. The two central conductors 66 are connected to one another by webs 68. This between the two center conductors lying webs 68 are equal in length to or only slightly greater than the length of the outer webs 67

As already mentioned, it should be avoided that two ends of the led out webs in the same transverse plane come lying down. This is possible through a special cutting process or by punching out, as has already been done was described during the manufacture of the webs, in which each of the central guide lines 66 is separated from one another. This punching process, which is necessary depending on a specific circuit, i.e. the separation between the center guide ladders 66 includes the complete removal of some for the connection of unneeded internal or external webs 67 or 68 or parts of the central guide ladder with a. During this process, parts of the webs located between the two central guide ladders 66 are also formed 68 each in the vicinity of a central guide ladders 66 affected, so that previously from the central guide ladders completely enclosed or firmly anchored between these victories 68 either by one or by the other Center guide ladder 66 are separated. That parting is in Pig. 11b. There are two perfect results separate conductor forms 57 which lie next to one another in the longitudinal direction. As in Pig. 1o described, At this stage, the center conductors 66 each have a strip of insulating material (63 in Pig. 1o)

If shown, gives for the sake of clarity this representation has been omitted in Pig »11. the the two conductor shapes 57 created in this way are more suitable Way held at their outer ends, and pushed into one another, as shown in Mg, 11c. In this Position, the ladder forms are embedded in plastic, and the ends of this protruding as already described, shortened to the required length.

As already described, individual, previously shown units or final conductor shapes enclosed in plastic have the disadvantage that the connection ends protruding from the plastic, as shown in FIG. 4b, are arranged in staggered rows. However, this complicates further processing of the structural units within a device, ie assembly to form a complete circuit, since the respective line / ungszugangs, which are necessary to complete the circuit, must be made in different lengths, which in turn makes automatic production more difficult. Especially when the ends of the webs, which protrude from a structural unit, not possible on each side of this assembly in a row, they can during manufacture verargten or damaged outstanding ä

Components lie within conductor arrangements according to the invention., Between these conductor arrangements is the space is provided so that the most frequently used components with their standardized dimensions can be accommodated in it. For this reason, it is favorable that the "two line groups 75 and 76 are designed separately from one another. These two groups of lines are then used for further processing to form a complete circuit in a particular Distance from each other arranged in parallel so that the components can be accommodated between them.

In Pig. 16 is the leader group 76 of the Pig. 15 shown disassembled or cut open. This arrangement comprises the four layers 76a, 76b, 76c and 76d ₉ in which the central guide parts of the ladder arrangement lie along the dash-dotted lines and the lateral webs are led away from it at a right angle. These metallic cable runs are in the Pig. 16, as already described, injected or embedded in plastic. The outer boundary line of the plastic body is indicated at 77. In this ar * folder; the lead-out connection ends of the webs to which the other circuit elements of the intended circuit are connected are shortened to a certain length, with the exception of connections III, IV and VI, which are used for the output and power supply of the circuit arrangement.

the units 78 and 8o. This arrangement is done in such a way that the connection ends of the components are led out are that they have the corresponding connection ends 82 of the Facing units 78 and 8o with which they are to be connected.

The assembly 79 aligns itself in their polygonal according to the largest component used between the units 78 and 8o and the number of those accommodated in this room Components. The connection ends left longer I to VI are used to connect the unit 79 to other circuits within a device,

Figure 18 shows a cross-section through the assembly shown in Figure 17. In this drawing it is shown how components of a conventional cylindrical shape, such as resistors or capacitors 83, are arranged between the assemblies 78 and 8o, whereby their connecting wires are fed in a bent state to the connecting ends 82. Based on the required connections, such components can be arranged within the structural units 78 and 8o either with their axes transverse to the plane of the conductor arrangement, as shown in Figure 18, or parallel to this plane be, with the terminal ends of the components may be soldered 82 of an assembly only at the upper or lower end located terminal lugs or connected. λ

In the part described so far, the connection lugs that protrude from the insulating part of the conductor arrangement and are used to connect the components within the circuit were described as flat connection lugs ending at a right angle. However, it is also possible to give you ¹ connecting lugs a shape that differs from the one previously described by means of additional work processes. For example, the connection lugs can also be formed from hollow cylinders in order to form a soldering trough for solder connection connections, or they form a channel in order to accommodate the connection wires, which can either be soldered or welded on. But it is

also possible either a direct connection to these connection lugs or indirect winding connection. The distance between the individual connection lugs is sufficient to accommodate the winding connections on the connection lugs with a tool to manufacture.

The arrangement of part of the overall device as shown in the. 17 and 18, consists in the arrangement of the circuit components between the two conductor arrangements or structural units 78 and 8o. This type of connection is easy to carry out by unskilled workers, as it is only necessary to connect the individual parts according to a specific circuit diagram. to use automatic wiring. The Pig arrangement has a small disadvantage. 17 and 18, however, namely that the terminal lugs of most circuit components, such as from Pig. 18, must be pre-bent before / they can be inserted between the units 78 and 8o. This need can be omitted in an embodiment as shown in section in Pig. 19. As a result, when executing according to Pig. 19 the molded parts of the conductor arrangement 78 and 8o * are made much smaller or lower, so that the connection ends 82 protruding from the molded part are longer on both sides, the connection wires of the components 83 can be connected directly to the connection ends 82 without there is a need to bend the connecting wires beforehand. For this version it is only necessary to use connection ends 82 · which, however, have the same length as the connection ends of the Pig. 18, f £ so that larger individual components, such as a transformer 84, can be connected to the ends of the webs 83 * through short connection ends.

As can be seen from Figures 18 and 19, such an assembly can be made by using conductor arrangements 78

So far it has been described how a structural unit or a module of an electrical device, such as, for example, V ⁰ S ¹ Ig. 17 shown, can be manufactured according to the present invention. A number, perhaps a large number, of such units are contained within an electrical device which have to be connected to one another within a device.

In I ¹ Ig ₀ 2o two structural units 85 and 86 are shown, which lie one behind the other in the longitudinal direction and are connected to one another by a plate 87, for example with a printed circuit or cable runs 88. The structural units 85 and 86 are provided with ends of the webs protruding from the injection, which are used to connect the structural units to other circuits, namely such web ends as they are in Eig. 17 are designated by I to VI. These web ends are long enough that they are arranged through bores in the plate 87 around the soldering eyes 89 which form the ends of the cable runs 88. These ends of the ± Z2 ± KX £ psxKgxx && webs are soldered within these soldering eyes 89. This connection represents both the mechanical and the electrical mounting. On such a plate 87, as it is shown in this example, some cable runs can also be attached, which in turn establish the connection between two or more structural units arranged next to one another, as shown in FIG Example happens between the units 85 and 86.
