o i 145130o in 145130

Opfindelsen angår en fastgørelsesindretning til fastgørelse af et antal elektriske komponenter til en instrumenttavle eller et kredsløbskort, således som nærmere angivet i krav l's indledning.The invention relates to a fastener for securing a plurality of electrical components to an instrument panel or circuit board, as further specified in the preamble of claim 1.

5 Fra tysk offentliggørelsesskrift nr. 2.135.454 kendes en indretning af denne art. I denne kendte indretning er sporene beregnet til at optage komponentens tilslutningsledninger, og hensigten med de udvidelser af sporene, der er udformet i disses bort fra instrumenttavlen eller kreds-10 løbskortet vendende ender, er under en maskinel bøjning af tilslutningsledningerne at sikre, at disse bøjes ind i sporene og følger disses retning og beliggenhed ved sporenes udmunding imod instrumenttavlen, med henblik på, at de skal kunne indføres i de dertil indrettede huller i instrument-15 tavlen, hvor de senere fastgøres ved lodning.5 German publication no. 2,135,454 discloses a device of this kind. In this known device, the grooves are intended to receive the component wiring lines, and the purpose of the extensions of the grooves formed at their ends away from the dashboard or circuit board facing ends is to ensure that they are bent during a mechanical bending of the connection wires. into the grooves and follows their direction and location at the mouths of the grooves against the dashboard so that they can be inserted into the holes provided in the dashboard, where they are subsequently secured by soldering.

''n I denne kendte konstruktion er det således en forudsætning, at fastgørelsesorganerne, der anvendes til at fastgøre de elektriske komponenter til instrumenttavlen eller kredsløbskortet, udgøres af komponenternes tilslutnings-20 ledninger. Dette medfører imidlertid dels, at tilslutnings ledningerne kan blive udsat for en uønsket mekanisk belastning, dels at friheden til at lægge tilslutningsledningerne i et hvilket som helst ønsket forløb er stærkt begrænset.Thus, in this known construction, it is a condition that the fasteners used to attach the electrical components to the dashboard or circuit board are constituted by the connecting wires of the components. However, this results, in part, that the connection wires can be subjected to an undesirable mechanical load and, in part, the freedom to lay the connection wires in any desired course is severely limited.

25 Fastgørelsesindretningen ifølge opfindelsen er ejendommelig ved den i krav l's kendetegnende del angivne udformning. Herved opnås dels, at tilslutningsledningerne frigøres fra den mekaniske belastning, dels at de - da de nu ikke længere skal fungere som fastgørelsesorganer - kan 30 lægges, hvor man måtte ønske det.The fastening device according to the invention is characterized by the design according to the characterizing part of claim 1. This is achieved partly because the connection cables are released from the mechanical load and partly that - since they no longer have to act as fastening means - they can be laid wherever desired.

Ved den i krav 2 angivne udformning opnås, at monteringsstiferne let kan indføres med hånden under anvendelse af forlængelsen som håndtag, der efter indsætningen brækkes af.In the configuration of claim 2, it is achieved that the mounting pins can be easily inserted by hand using the extension as handle which is broken off after insertion.

35 Ved den i krav 3 angivne udformning opnås en forbedring af fastgørelsesorganernes pålidelighed, idet 0 2 145130 de fremspring på sporets sider, der står tilbage efter underskæringen, tilbageholder den på monteringsstiftens ende udformede udvidelse imod utilsigtet udbøjning, som ellers kunne have medført, at monteringsstiften gik ud af 5 holdeindgreb med komponenten.The design of claim 3 provides an improvement in the reliability of the fasteners, with the projections on the sides of the groove remaining after the undercut retaining the extension formed at the end of the mounting pin against unintended bending which otherwise could have caused the mounting pin went out of 5 holding engagement with the component.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken fig. 1 viser en elektrisk komponent med monteringsstifter og tilslutningsledninger samt en del af et kreds-10 løbskort med huller til komponentens fastgørelse, fig. 2 i større målestok et til en monteringsstift beregnet spor i den elektriske komponent samt et stykke af kredsløbskortet, og fig. 3 en monteringsstift.The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 shows an electrical component with mounting pins and connecting wires as well as a portion of a circuit board with holes for fixing the component; FIG. 2 is an enlarged view of a groove in the electrical component for a mounting pin and a piece of the circuit board; and FIG. 3 a mounting pin.

15 En elektrisk komponent fastgøres, som det fremgår af fig. 1, med to monteringsstifter 2 i et kredsløbskort 6.15 An electrical component is attached as shown in FIG. 1, with two mounting pins 2 in a circuit board 6.

I den elektriske komponents vægge findes fire spor 3, der er indrettet og placeret i hjørnerne i et rektangel, og hvor monteringsstifterne 2 er indført i to af disse spor 20 beliggende diagonalt i forhold til hinanden.In the walls of the electrical component are four grooves 3 arranged and positioned in the corners of a rectangle, and the mounting pins 2 are inserted diagonally in relation to each other in two of these grooves 20.

Monteringsstifterne 2 er ført gennem huller 7 i kredsløbskortet 6 og er på kredsløbskortets anden side bøjede. For at fastgørelsen yderligere skal sikres, er den ombøjede del af monteringsstiften loddet almindeligvis 25 samtidig med lodningen af apparatets tilslutningstråde.The mounting pins 2 are passed through holes 7 in the circuit board 6 and are bent on the other side of the circuit board. In order to further secure the fastening, the bent part of the mounting pin is generally soldered at the same time as the soldering of the connecting wires of the apparatus.

Komponentens placering på kredsløbskortet er yderligere bestemt af to tilpasningsstifter 4, der passer ind i til disse beregnede huller i kredsløbskortet 6.The location of the component on the circuit board is further determined by two alignment pins 4 that fit into these calculated holes in the circuit board 6.

Komponenten er på en og samme side forsynet med to 30 tilpasningsstifter 4 og to tilpasningshuller 5 anbragt i hjørnerne af et rektangel, hvor tilpasningsstifterne er anbragt i hjørner beliggende diagonalt over for hinanden. Også apparatets modstående side er forsynet med to tilpasningsstifter og to tilpasningshuller. Tilpas-35 ningsstifterne og tilpasningshullerne på de to sider er anbragt symmetrisk således, at der over for en tilpasningsstift ligger et tilpasningshul og omvendt. Symmetrien 145130 0 3 gør det muligt at anbringe to eller flere komponenter på hinanden, tilpasningsstifterne og tilpasningshullerne 5 bidrager til at give stabilitet til en sådan sammensat gruppe af komponenter. I sådanne tilfælde anvendes til 5 fastgørelsen længere monteringsstifter, end når kun ét apparat skal fastgøres.The component is provided, on one and the same side, with two adapter pins 4 and two adapter holes 5 disposed in the corners of a rectangle, the adapter pins being disposed diagonally opposite one another. The opposite side of the device is also provided with two adapter pins and two adapter holes. The alignment pins and the adjustment holes on the two sides are arranged symmetrically such that there is an alignment hole opposite an adjustment pin and vice versa. The symmetry 145130 0 3 makes it possible to place two or more components on one another, the adapter pins and adapter holes 5 contributing to providing stability to such a composite group of components. In such cases, the mounting pins use longer mounting pins than when only one device is to be attached.

Komponenten har tilslutningstråde 8, der er bøjet og ført gennem dertil beregnede huller i kredsløbskortet 6. Tilslutningstrådene er loddet til trykte ledninger på 10 kredsløbskortet. I det beskrevne eksempel har kredsløbskortet to huller til tilslutningstrådene. Der kan også tilvejebringes huller til et større antal tilslutningstråde fra en komponent eller en gruppe af komponenter.The component has connecting wires 8 which are bent and passed through designated holes in the circuit board 6. The connecting wires are soldered to printed wires on the 10 circuit board. In the example described, the circuit board has two holes for the connecting wires. Holes may also be provided for a greater number of connecting wires from a component or group of components.

Sporene 3 for monteringsstifterne 2 er, som vist 15 i fig. 2/udvidet i den ene ende til en svalehaleformet udvidelse 11 til modtagelse af en svalehaleformet del i monteringsstiftens ene ende. Udvidelsen 11 er rettet med sin største bredde i et plan parallelt med apparatets l's side.The grooves 3 of the mounting pins 2 are, as shown 15 in FIG. 2 / extended at one end to a dovetail extension 11 to receive a dovetail portion at one end of the mounting pin. The extension 11 is directed with its greatest width in a plane parallel to the side of the apparatus 1.

20 De huller i kredsløbskortet 6, der er beregnet til monteringsstifterne 2, ligger i en skillelinie mellem to apparater. Monteringsstiften kommer derved til at trænge ind på det tilstødende apparats plads. Dette er forklaringen på, hvorfor hvert elektrisk apparat har fire spor 3 og 25 ikke kun to spor. Kravene om symmetri hos det elektriske apparat har ført til, at også de spor, der ikke anvendes til fastgørelse ved hjælp af monteringsstifter, også har en svalehaleformet udvidelse 11, men beliggende i den ende af sporet 3, der vender imod kredsløbskortet 6.The holes in the circuit board 6 intended for the mounting pins 2 lie in a dividing line between two devices. The mounting pin will thereby penetrate the space of the adjacent device. This explains why each electrical appliance has four tracks 3 and 25 not just two tracks. The requirements for symmetry of the electrical apparatus have also led to the grooves not used for fastening by means of mounting pins also having a dovetail-shaped extension 11, but located at the end of the groove 3 facing the circuit board 6.

30 De i kredsløbskortet fremstillede huller 7 for hvert apparat, i det beskrevne tilfælde seks huller, se inden for indramningen 9 i fig. 1, er anbragt med afstande, der er valgt ifølge et for kredsløbskort almindeligt modulsystem, hvor modulet er 2,54 mm, 0,1". Komponenterne, 35 der refereres til, har små dimensioner, og den beskrevne komponent 1 har længden 15 mm, 0,6", bredden 10 mm, 0,4” og højden 7,6 mm, 0,3".30 The holes 7 made in the circuit board for each apparatus, in the case described six holes, see within the frame 9 in FIG. 1 is spaced at distances selected according to a conventional circuit board modular system where the module is 2.54 mm, 0.1 ". The components 35 referred to have small dimensions and the component 1 described is 15 mm in length. , 0.6 ", width 10 mm, 0.4" and height 7.6 mm, 0.3 ".

Monteringsstiften 2, der er vist i fig. 3, er stanset ud af en metalplade med en tykkelse på 0,5 mm.The mounting pin 2 shown in FIG. 3, is punched out of a metal plate having a thickness of 0.5 mm.

Den af monteringsstiftens ender 14, der er beregnet til at føres ind i kredsløbskortet 6, går ud i en symme-5 trisk spids med en vinkel på 30°. Monteringsstiftens anden ende, der er beregnet til at indlægges i udvidelsen 11 i den elektriske komponents spor 3, er udformet med en svalehale 15 med større bredde end monteringsstiften i øvrigt.The end 14 of the mounting pin 14 intended to be inserted into the circuit board 6 extends into a symmetrical tip at an angle of 30 °. The other end of the mounting pin, which is intended to be inserted into the extension 11 of the electrical component groove 3, is formed with a dovetail 15 of greater width than the mounting pin in general.

Som vist i fig. 2, kan udvidelsen 11 i sporet 3 10 være dannet ved underskæring, så at de tilbagestående yderkanter forhindrer utilsigtet udbøjning af monteringsstifternes svalehaleformede ende 15.As shown in FIG. 2, the extension 11 in the groove 310 may be formed by undercutting so that the recessed outer edges prevent inadvertent bending of the dovetail-shaped end 15 of the mounting pins.

I de tilfælde, hvor monteringsstiften 2 indsættes manuelt, anvendes en type monteringsstifter, der ved den 15 svalehaleformede ende 15 er forsynet med en som et håndtag virkende forlængelse 16, der er beregnet til at lette monteringsstiftens indsætning. Nærmest svalehalen har forlængelsen 16 en indsnøring 17, hvorved det er muligt at bortbryde forlængelsen 16, efter at monterings-20 stiften 2 er indsat på sin plads i den elektriske komponent 1 og kredsløbskortet 6.In cases where the mounting pin 2 is inserted manually, a type of mounting pin is used, which at the dovetail-shaped end 15 is provided with an extension 16 acting as a handle intended to facilitate the insertion of the mounting pin. Closest to the dovetail, the extension 16 has a notch 17, which makes it possible to break the extension 16 after the mounting pin 2 is inserted in its place in the electrical component 1 and the circuit board 6.

Monteringsstifter, der er beregnet til at monteres maskinelt, har ikke forlængelsen 16.Mounting pins designed to be machined do not have the extension 16.
