Procedure for the production a flat course of a wiring harness

PATEblTAMT class: 21 e2 57 lnt. Cl.: H 02 g PATENT SPECIFICATION No. 266963 BROW, BOVERI & CIE. CORPORATION IN MANNHEIM (GERMANY) procedure for the production of a flat course wiring harness announced at the 25.April 1966 (A 3874/66); stressed priority: Patent claims 1-3 of the 21.Jänner 1966 (B 85490 VIIId/21c), patent claim 4 of the 18.Mai 1965 (B 81972 VIlld/21c) (registrations in Germany). Beginning of the patent duration: 15.März 1968. To the connection of electrical parts in switchgear cabinets and/or Rechenund office machines are usually combined the main lines to wiring harnesses. Like that flat course wiring harnesses are become known, which unite from thin, about tenth millimeters strong flat course leaders with plastic foils as insulating spacers are developed. In distances connector lugs are intended for soldering further branches on or for screwing the flat course leaders onto clamps od.dgl, over the entire length. The Flachbahn Kabelbanm is stretched or more einoder several times bent depending upon the requirement, whereby depending upon the appropriate situation of the clamps the connector lugs can be bent in different directions. The connector lugs of the individual flat course leaders are arranged generally such that the individual connector lugs do not cover äch mutually, but always lie side by side. The flat course leaders manufactured made of volume copper result in a comblike thing, with which the individual teeth, i.e. the connector lugs, are transferred in each case somewhat more than by the thickness of the leader and its isolation. Aforementioned arrangement requires ten leaders, that are different in the execution of the Auschlufifahnen for a wiring harness with for example ten flat course leaders. For the manufacturing of the well-known flat course wiring harnesses so far a complete cut was intended for each flat course leader. With a wiring harness with ten flat course leaders this means the acquisition of ten punching tools. The punching tools are so furnished that they let the desired number of connector lugs stand on each flat course leader only, their longitudinal dimensions however outward due to following bending around the thickness of an insulating Flachbahnhiters become larger in each case. From the multiplicity of the tools and as a result of the Flachbahnlelter divided into many manufacturing lots arise small in each case numbers of items, which make this punching procedure disproportionately uneconomic. A further disadvantage in the production of the flat course leaders of a wiring harness arises as a result of the Ansehlußfahnen bent with application of a complete cut already into the desired situation. When packaging the flat course leaders when assembly assembling for the production of the actual flat course wiring harness often larger difficulties develop because of the high demands for accuracy. By the substantial expenditures for the preparation time when punching the different flat course leader variants, by high tooling expenses for the many complete cuts and by the large requirements of the accuracy with a forms and packaging of the wiring harness the production becomes too complex and thus uneconomic. The invention avoids these disadvantages and makes an economic manufacturing possible with small tooling expenses. It concerns a procedure for the production of a flat course wiring harness with several by plastic laminations from each other isolated and stuck together and/or verbackenen flat course leaders. It is characterized by that first all flat course leaders completely homogenously with ever a grSBeren Anzah! punched out by connector lugs as later to be needed, those longer are arranged and in Pakefform pressed than them at the finished Kabelbanm to be have and afterwards from the individual Flaehbahnleitern the redundant AnschlnBfahnen be removed and then the Flaehbahnleiter covered and lie-transferred, fall in love and/or merged or will bake and that the edges of the F1aehbahn-Kabelbaumes covered with casting resin and/or. are sealed. The punched flat course leaders have thereafter the drawn appearance that mostly several are present, for example over the half Flaehbahnleiteflänge leading groups of differently broad and long connector lugs. The individual groups of connector lugs again are always so trained that between the connector lugs a certain distance predominates, which is substantially larger than the distance for the flashover voltage. The width of the volume copper, from which the ladder it is manufactured is selected always in such a way that the longest connector lug is still covered by the range. The length of these connector lugs and the width of the leader are thus considered in the punching tool. Is thus only for each basic form of a flat course leader a punching tool necessary, which is so laid out that all occurring variants are considered regarding number and arrangement of the connector lugs. In further arrangement of the procedure in accordance with the invention each Flachbahrdeiter punches out itself fiir in the subsequent step from a Kupferband, with which the working strokes are so co-ordinated in their size that a right-angled ahstehende connector lug and/or one or more right-angled which are away soldering connection flags and/or groups of flags, which are actually used remains standing in each case, and that, like already vorbesehrieben, the flat course leaders after it covered and lie-transferred arranged and in package form pressed, falls in love and/or merged or will bake and that also the edges of the Flaehbahn wiring harness with casting resin covered and/or sealed is. The individual working strokes before were so adjusted that eh Kabelbanm results, with which the distance of the connector lugs and those of the soldering connection flags and/or - groups of flags among themselves is larger than the distance of the parts to the control of the flashover voltages. The connector lugs according to invention of the wiring harness manufactured in the procedure have the advantage to be from a uniform size to. The erf'mdungsgemäße procedure plans furthermore that the covered, yet did not weld, fell in love and/or to verbackenen or versehmolzenen flat course leaders in Pakeffom/laughs to be presented, clamped one-sided and depending upon need angularly bent. Before side of the änBersten Flaehbahrdeiters in the bending device is clamped flat and the other end up to the respective attack is bent. With the next leaders the bending device is shifted so in each case that the bends become shorter including its isolation around the thickness of a leader. In addition, the packaged wiring harness, naturally before that, can be clamped flat to cheeks at an end into a Biegeeintichtung. Then the other end up to the respective attack and on the intended length is bent together cut, is called the flat course leaders must outward around the thickness of an insulating Flaehbahnleiters long than the nominal dimension be in each case, so that the bent finished wiring harness has everywhere the prescribed length. Finally the wiring harness is pressed in the before-packaged way and stuck together and/or merged or bakes. Thus the individual Flaehbahrdeiter is firmly connected. A special advantage of the procedure after the invention is that at finished the packaged, injected, stuck together and/or verbackenen or merged flat course wiring harness the connector lugs and/or the ends of the flat course wiring harness depending upon the requirement to be bent, punched and on the intended length be cut. The advantage of this additional treatment is particularly in that when laminating the individual Flaehbahnleiter larger tolerances may be taken up. Laminating and isolating the leaders is likewise simpler, since only except the possible buckling of the leader flat and not deformed ladder application find. In a last job become, as already mentioned, those covered and/or seal for edges of the flat course wiring harness with casting resin. Thus the foils supernatant at the leader edges are specified and an estimate is made impossible from leader to leader. These stuck together, verbackenen or merged wiring harnesses are used in place of the single wires used so far and/or from these manufactured wiring harnesses ever more. Their outstanding good space utilization and the self-supporting characteristics of the wiring harnesses particularly predestine these as Zuund derivatives in Rechenund BüromaschinenhersteUung. Directly the lines led more überoder next to each other are down-inductively and at the same time highly capacitive and deliver thus for the plant a good means for Phasenkompensation. The flat developed wiring harnesses are so space-saving that they are used above all, where the past line technology failed and the switchgear cabinets would have had to be increased because of the Zuund of derivative wires. Contrary to that so far have the descriptive flat course wiring harnesses the special advantage admitted that the flat course leaders are to-punched in cost-saving way in large quantities with only one tool. By simple punching out and the lamination made thereafter, by bending and pressing the leaders together these flat course wiring harnesses are suitable primarily for the assembly-line production. Pressing the insulating ladder together in heated forms and special Backbzw. Fusion technology result in a flat course wiring harness with the self-supporting characteristics mentioned, which results in a perfectly isolated Mehffachleiter with the before-descriptive qualities together with the Gießharzäberzug of the leader edges. The individual flat course leaders and their isolation are so firmly connected that the heating up can be exhausted by the load of individual leaders easily and/or. outward radiates. Into the Fig.1 to 9 of the CPU! chnungen is partly in look-figurative representation shown a preferential Ansführungsbeispiel. Fig.1 places a flat course leader --1-- with a group of connector lugs --2--for later bolt connections and a group of connector lugs --3-- for later soldering connections. All occurring connector lugs are in such a manner trained on the flat course leader that a Flachbahn Kabelbanm with for example ten Zuund Ableitnngen is possible. In the Fig.2 and 3 is the further course of the prefabricated flat course leaders --1-- to recognize. The next step in the treatment is the distance of the surplus connections. With the extreme FlachbahnMter --1-- (Fig.2) the first screw connection is after the distance of all surplus Anschltisse --2-- and the first soldering connection --3-- each group stopped. A further step in the treatment (Fig.3) shows the second flat course leader --1-- with one around a step Schranbanschlußfahne shifted --2-- and a soldering connection flag likewise shifted by a step --3--. The unnecessary Anschlaßfahnen is removed with the help of a simple separation cut. Cutting the surplus connector lugs off takes place individually on a tool to-prepared with a feed feature. The separation stamp is in such a way selected in the dimensions that with a working stroke the smallest demanded distance between the Ansehlußfahnen can be achieved. With desired larger distance between the conclusion flags several working strokes are necessary. The Fig.4 shows a flat course wiring harness --4-- with five packaged and verbackenen flat course leaders --1--, those with the right angle --5-- before sticking together and/or that cheeks of the Kabelbanmes to be bent. The Schranbanschlüsse --2-- are still rough and have the maximum length of the foremost and/or rear leader. On the other hand are the soldering connections --3-- trained, since hiefllr no further treatment is necessary. In the Fig.5 is from four packaged and stuck together with one another and/or verbackenen flat course leaders --1-- existing Flachbahnkabelbanm --4-- represented. The Kabelbanm --4-- is again rectangular --5-- bent. The Schranbanschlüsse --2-- are curved, punched and circumcisedly. The soldering connection flags --3-- continue to be not worked on. In the Fig.6 is represented still another advancement of the finished flat course wiring harness. On the right side of this wiring harness the soldering connection flags are completely distant. The end of the wiring harness against it is anfgespleist and the accordingly stripped flat course leaders is with Schranbanschlässen --6-- provided. Fig.7 shows a flat course leader --7-- with a connector lug --2-- for later bolt connections and a group of soldering connection flags --3 '-- for later Lötoder Schweißanschlässe. The connector lug --2-- it is again in such a way trained that the longest of the occurring connector lugs is considered. The connector lugs --2-- and the groups of soldering connection flags --3 '-- of the full width of material with the help of an all-purpose tool are cut out. On a feed rail and a template, which are manufactured after the desired flat course leader, the operation number is specified. After the representation of the Fig.7 is the connector lug --2-- in several working strokes free-cut. The group of soldering connection flags is simultaneous --3 '-- with a further tool free-punched. Both tools are united to one. By a meaningful mechanism it is possible to determine the rhythm of the working strokes. By an appropriate bolting device only or the other tool in each case always works. The stamp to free cuts of the connector lugs --2-- it is in such a way selected that the kleinstzulässige distance between two lie-shifted connector lugs --2-- one keeps. Against it if a larger distance between the lie-transferred connector lugs is to be planned, several working strokes are necessary. The tool fiir the groups of soldering connection flags --3 '-- is exactly the same trained as before-descriptive. It is however in several variants present, so that the possibility exists of manufacturing single soldering connections or Grupperdötanschlüsse. In the Fig.8 and 9 are still two further flat course leader situations --7-- a wiring harness represented. Hiebei is in each case the next connector lug --2-- as well as the next group of soldering connections of 3 '-- free-cut. After the assembly of the number of flat course leaders planned for a wiring harness--7-- the Kabe [baum-Fig.4 to 6. this Kabelbanm develops is again before sticking together and cheeks rectangular --5-- abgekröpft. For the difference of the Fig.7 to 9 are in place of the Lötanschlußgrnppen --3 '-- Single soldering connections --3-- planned. The execution according to invention is suitable above all, where it depends on self-supporting, down-inductive or hochkapazifive ladder. The flat course wiring harnesses are implemented particularly flat and space-saving and exhibit with their relatively good space utilization opposite the single leaders used so far many advantages.
