Description

Verfahren zur Befestigung eines Flachsteckers in dem Sockel eines elektrischen Bauelementes sowie nach dem Verfahren hergestellter SockelMethod for fastening a flat plug in the base of an electrical component and base produced by the method

Die Erfindung betrifft ein Verfahren zur Befestigung eines Flachsteckers in dem aus Isolierstoff bestehenden Sockel eines elektrischen Bauelementes, beispielsweise eines Relais, wobei der Flachstecker durch einen Durchbruch des flachen Sockelbodens gesteckt wird, bis er sich mit mindestens einer angeformten Schulter auf einer ersten Oberfläche des Sockelbodens abstützt, und dann mittels mindestens eines aus dem Stecker herausgeformten Vorsprungs an der gegenüberliegenden zweiten Oberfläche des Sockelbodens verspannt wird. Außerdem betrifft die Erfindung einen danach hergestellten Sockel sowie die Verwendung eines solchen Sockels in einem elektromagnetischen Relais.The invention relates to a method for fastening a tab connector in the socket of an electrical component, for example a relay, which is made of insulating material, the tab connector being inserted through an opening in the flat base plate until it is supported on at least one molded shoulder on a first surface of the base plate , and is then clamped to the opposite second surface of the base base by means of at least one projection molded out of the plug. In addition, the invention relates to a base manufactured according to this and the use of such a base in an electromagnetic relay.

Eine derartige Befestigung eines Flachsteckers ist beispielsweise aus der EP-A-0 281 950 zu ersehen. Dort sind die Flachstecker jeweils mit schräg ausgestellten Rastlappen versehen, die beim Durchstecken des Steckers durch den Sockel etwas federnd nachgeben und sich dann an der Unterseite des Sockels nach Art von Widerhaken verspannen. Derartige gegen die Einsteckrichtung aufgestellte Befestigungslappen können auch nach dem Durchstecken aus dem Steckermaterial herausgedrückt werden. Allerdings ergibt eine solche Verrastung nicht immer einen ausreichend stabilen Festsitz, während für ein nachträgliches Herausdrücken die Angriffsmöglichkeit von Werkzeugen ungünstig ist. Auch Verspannungen können in diesem Fall hervorgerufen werden. Diese Art der Befestigung erfordert auch Elastizität des Sockelkunststoffes; spröde Kunststoffe sind hierfür ungeeignet.Such a fastening of a flat plug can be seen, for example, from EP-A-0 281 950. There, the flat plugs are each provided with obliquely flared locking tabs that yield somewhat resiliently when the plug is inserted through the base and then brace on the underside of the base in the manner of barbs. Such fastening tabs set up against the direction of insertion can also be pressed out of the plug material after insertion. However, such a latching does not always result in a sufficiently stable tight fit, while the possibility of attack by tools is unfavorable for subsequent pressing out. Tension can also be caused in this case. This type of attachment also requires elasticity of the base plastic; brittle plastics are unsuitable for this.

Üblich ist bei derartigen Flachsteckern auch ein Verkerben der Steckerelemente nach dem Durchstecken, wobei jeweils an den Schmalseiten der Stecker Kerben eingeschlagen und die freigeschnittenen Kerbnasen nach außen gedrückt werden. Auch mit diesem Verfahren ist nicht immer ein zuverlässiger Festsitz, insbesondere beim Auftreten starker Kräfte entgegen der Steckrichtung, zu erreichen. Außerdem verursacht das Kerben Verspannungen im Durchbruch des Sockels, wodurch insbesondere an den Kanten des Durchbruchs leicht Kunststoffmaterial ausbricht.In the case of such flat plugs, it is also customary for the plug elements to be jagged after they have been pushed through, in each case to the Narrow sides of the connector notches are hammered in and the notched notches are pressed outwards. With this method, too, a reliable tight fit cannot always be achieved, particularly when strong forces occur counter to the direction of insertion. In addition, the notching causes tension in the opening of the base, as a result of which plastic material breaks out particularly at the edges of the opening.

Aus der FR-A-1 176 688 ist es bekannt, einen flachen Anschlußstift zur Befestigung in einer Ausnehmung einer Leiterplatte oder eines Sockels mit langgestreckten geprägten Rippen auf den Flachseiten zu versehen. Die Fixierung des Stiftes erfolgt allerdings auch dort durch Einkerben an den Schmalseiten, wodurch wiederum die oben erwähnten Verspannungen an den Kanten des Kunststoffmaterials auftreten.From FR-A-1 176 688 it is known to provide a flat connecting pin for fastening in a recess in a printed circuit board or a base with elongated embossed ribs on the flat sides. However, the pin is also fixed there by notches on the narrow sides, as a result of which the above-mentioned tension occurs on the edges of the plastic material.

Insbesondere dann, wenn die Stecker und damit auch die Durchbrüche für die Stecker nahe am Rand des Sockels angeordnet sind, führen die bekannten Verfahren zu einer Deformierung oder sogar zum Reißen des Kunststoffmaterials am Sockelrand, oder es ist zumindest wegen des Ausweichens des Kunststoffes kein guter Festsitz für den Stecker erzielbar.In particular, if the plugs and thus the openings for the plugs are arranged close to the edge of the base, the known methods lead to deformation or even tearing of the plastic material at the base edge, or it is at least not a good tight fit because of the plastic's evasion achievable for the plug.

Ziel der Erfindung ist es, ein Verfahren zur Befestigung eines Flachsteckers im Sockel eines elektrischen Bauelementes, wie eingangs erwähnt, anzugeben, mit welchem auf fertigungstechnisch relativ einfache Weise ein zuverlässiger Festsitz des jeweiligen Flachsteckers in dem Sockel gewährleistet werden kann. Unter dem Begriff eines Flachsteckers sei hier generell ein aus flachem Blech bestehendes Anschlußelement verstanden. Ein bevorzugter Anwendungsfall sind die für Steckanschlüsse bei Relais und dergleichen verwendeten Flachstecker oder Faston-Stekker, doch ist die Erfindung genauso anwendbar für flache Anschlußelemente, welche für sonstige Arten der Kontaktierung, wie Löten und dergleichen bestimmt sind, wozu sie beispielsweise an den Enden in eine beliebige Form geschnitten sein können.The aim of the invention is to provide a method for fastening a flat connector in the base of an electrical component, as mentioned at the beginning, with which a reliable tight fit of the respective flat connector in the base can be ensured in a relatively simple manner in terms of production technology. The term “flat connector” is generally understood to mean a connection element consisting of flat sheet metal. A preferred application are the flat plugs or Faston plugs used for plug connections in relays and the like, but the invention can also be used for flat connection elements which are intended for other types of contacting, such as soldering and the like, for which they are terminated in a any shape can be cut.

Erfindungsgemäß wird das obengenannte Ziel mit den nachfolgenden Verfahrensschritten erreicht:

  • a) Aus mindestens einer der beiden Flachseiten des Steckers wird vor dem Einstecken in den Sockel zumindest eine in Steckrichtung langgestreckte Rippe geprägt, welche nach dem Einstecken zumindest teilweise jenseits des Durchbruchs liegt, und
  • b) der aus dem Durchbruch überstehende Teil der Rippe wird von ihrem äußeren Ende ausgehend in Richtung auf den Sockel vom Steckerkörper abgeschält und gegen die zweite Oberfläche des Sockelbodens hin deformiert.
According to the invention, the above-mentioned goal is achieved with the following process steps:
  • a) at least one rib which is elongated in the direction of insertion is embossed from at least one of the two flat sides of the plug before being inserted into the base, and which is at least partially beyond the opening after insertion, and
  • b) the part of the rib protruding from the opening is peeled off from its outer end in the direction of the base from the plug body and deformed towards the second surface of the base base.

Bei der Erfindung wird also eine aus dem Blechmaterial zuvor herausgeprägte Rippe entgegen der Steckrichtung in einem kombi- nierten Schäl- und Stauchvorgang deformiert und gegen die zweite Oberfläche des Sockelbodens, also gegen die Unterseite des Sockels, verspannt. Durch den Abschälvorgang tritt nicht wie bei bisherigen Verfahren ein Stauchen bzw. eine Verspannung im Durchbruch selbst auf, vielmehr wird der außerhalb des Durchbruchs liegende Teil der Rippe in Form eines Spanes abgehoben und zur Sockelunterseite hin gestaucht und gebogen. So wird eine Haltenase gebildet, die über die Kante des Durchbruchs hinweggreift und einen sicheren Formschluß mit der Sockelunterseite bildet.In the case of the invention, a rib previously embossed from the sheet metal material is deformed in a combined peeling and upsetting process against the direction of insertion and is braced against the second surface of the base base, that is to say against the underside of the base. The peeling process does not result in compression or tension in the opening itself, as in previous methods, rather the part of the rib lying outside the opening is lifted off in the form of a chip and compressed and bent towards the underside of the base. In this way, a retaining lug is formed which extends over the edge of the opening and forms a secure positive connection with the underside of the base.

Eine besonders vorteilhafte Ausgestaltung des Verfahrens sieht vor, daß die Rippe an ihrem äußeren Ende mit einem Vorsprung gegenüber ihrem übrigen Teil, insbesondere gegenüber dem im Bereich der Sockelkante liegenden Teil versehen wird. So erhält die Rippe beispielsweise einen stufenförmigen Verlauf mit einer angeprägten Nase oder einer Verdickung am äußeren Ende. Dann ergibt sich ein besonders günstiges Abschälen mit Abwickeln des abgeschälten Materials nach außen, da das Schälwerkzeug mit der vorstehenden Nase eine große Angriffsfläche erfaßt, während die sich zum Sockel hin verjüngende Rippe leicht abgeschält werden kann, ohne daß eine starke Stauchverformung in den Bereich des Sokkeldurchbruchs hinein wirkt, welche dort zu den erwähnten Verspannungen führen könnte. Im Fall des Vorsprungs an der Rippe ergibt sich zwangsläufig beim voll eingesteckten Stecker ein Abstand zwischen der Rippenoberfläche und der entsprechenden Kante des Sockeldurchbruchs, da dieser Sockeldurchbruch an der betreffenden Stelle weit genug für das Durchstecken des Vorsprungs gehalten werden muß. Durch diesen Zwischenraum nach dem Durchstecken können selbst dann keine Verspannungen im Durchbruch selbst auftreten, wenn die Rippe auch in diesen Bereich hinein gestaucht wird. In jedem Fall wird auch die Kante des Durchbruchs durch das Verformen des Steckers nicht beeinträchtigt.A particularly advantageous embodiment of the method provides that the rib is provided at its outer end with a projection over its remaining part, in particular over the part lying in the region of the base edge. For example, the rib has a step-like shape with an embossed nose or a thickening at the outer end. Then there is a particularly favorable peeling with unwinding of the peeled material to the outside, since the peeling tool with the protruding nose covers a large contact surface, while the rib tapering towards the base can easily be peeled off without a strong compression deformation in the area of the socket opening acts in there, which could lead to the mentioned tension. In the case of the projection on the rib, there is inevitably a distance between the rib surface and the corresponding edge of the socket opening when the plug is fully inserted, since this socket opening must be held far enough at the relevant point for the projection to be inserted. Because of this space after insertion, no tension in the opening can occur occur even if the rib is also pushed into this area. In any case, the edge of the opening is not affected by the deformation of the connector.

Für die praktische Ausführung ist es vorteilhaft, an dem Stekker zwei Rippen auszuprägen und zum Sockelboden hin zu deformieren, wodurch sich eine Verteilung der Haltekräfte ergibt. Möglich ist es auch, an dem Stecker nach beiden Flachseiten hin Rippen herauszuprägen und zur Bildung von Haltenasen abzuschälen.For the practical implementation, it is advantageous to emboss two ribs on the connector and to deform them towards the base, which results in a distribution of the holding forces. It is also possible to emboss ribs on both sides of the plug and peel them off to form retaining lugs.

Ein erfindungsgemäß gewonnener Sockel mit einem oder mehreren Flachsteckern ist erfindungsgemäß dadurch gekennzeichnet, daß mindestens eine aus einer Flachseite des Steckers herausgeprägte und entgegen der Einsteckrichtung gebogene Haltenase auf der zweiten Oberfläche des Sockelbodens aufliegt. Dabei ist es zweckmäßig, daß der Durchbruch im Sockel jeweils dem Querschnitt des durchgesteckten Flachsteckers entspricht und an seinen Seitenwänden jeweils Führungskanäle für die herausgeprägten Rippen aufweist. Zur Abdichtung dieser Führungskanäle nach dem Durchstecken des Flachsteckers sind an diesem vorzugsweise zusätzliche Abdichtnasen angeprägt, die den vollen Querschnitt der Führungskanäle verschließen.A base obtained according to the invention with one or more flat plugs is characterized according to the invention in that at least one retaining lug embossed from a flat side of the plug and bent against the direction of insertion rests on the second surface of the base base. It is expedient that the opening in the base corresponds to the cross section of the inserted flat connector and has guide channels for the embossed ribs on its side walls. To seal these guide channels after the flat connector has been pushed through, additional sealing lugs are preferably stamped on it, which seal the full cross section of the guide channels.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. Es zeigt

  • Figur 1 einen schematisiert dargestellten Relaissockel mit einem einzusteckenden Flachstecker in perspektivischer Darstellung,
  • Figur 2 und 3 jeweils eine Detailansicht des im Sockel eingesteckten Flachsteckers im Schnitt und in Draufsicht,
  • Figur 4 eine Darstellung des Deformationsvorgangs zur Fixierung des Flachsteckers.
The invention is explained in more detail using an exemplary embodiment with reference to the drawing. It shows
  • FIG. 1 shows a schematically illustrated relay base with a flat plug to be inserted in a perspective view,
  • FIGS. 2 and 3 each show a detail view of the flat plug inserted in the base, in section and in plan view,
  • Figure 4 is an illustration of the deformation process for fixing the tab.

Die Figur 1 zeigt einen schematisierten Relaissockel 1, dessen Sockelboden 2 mehrere Durchbrüche 3 zur Aufnahme von Flachstekkern 4 (nur einer gezeigt) besitzt. Seitlich von den Durchbrüchen können, wie an einem Beispiel gezeigt, zusätzliche Stützrippen 5 angeformt sein, um die Durchstecklänge für den Flachstecker 4 zu vergrößern und damit die Stabilität zu erhöhen. Der Flachstecker 4 kann an der Oberseite beliebig geschnitten und gebogen sein; er dient beispielsweise zum Anschweißen von Kontaktelementen oder Drähten zur Führung von Kontakt- oder Spulenstrom. Jedenfalls besitzt dieser Stecker 4 eine oder zwei Schultern 6, mit denen er sich nach dem Einstecken in den Sokkel 1 an der ersten Seite, d. h. der Oberseite des Sockelbodens 2, abstützt. Außerdem besitzt der Flachstecker im vorliegenden Fall zwei nach einer Flachseite herausgeprägte Rippen 7, welche sich in Steckrichtung erstrecken. An ihren distalen Enden 7a, d. h. an den zum freien Steckerende 4a hin gerichteten Enden, besitzen sie eine stufenförmig erhöhte Nase 8. Zum Durchstecken der Rippen 7 sind in den Seitenwänden der Durchbrüche 3 jeweils Führungskanäle 9 ausgeformt, deren Tiefe der Höhe der Nasen 8 entspricht. Somit kann der Flachstecker 4 bei der Montage mit seinem Ende 4a in einen zugehörigen Durchbruch 3 eingesteckt werden, bis die Schultern 6 auf dem Sockelboden 2 aufstehen und die Nasen 8 sowie ein Teil der Rippen 7 an der Unterseite des Sockels vorstehen.FIG. 1 shows a schematic relay base 1, the base base 2 of which has a plurality of openings 3 for receiving flat-core 4 (only one shown). As shown in an example, additional support ribs 5 can be formed on the side of the openings in order to increase the push-through length for the flat plug 4 and thus to increase the stability. The flat connector 4 can be cut and bent at the top; it is used, for example, for welding contact elements or wires to conduct contact or coil current. In any case, this plug 4 has one or two shoulders 6, with which it can be plugged into the socket 1 on the first side, i. H. the top of the base 2, supports. In addition, the flat plug in the present case has two ribs 7 which are embossed on a flat side and extend in the plugging direction. At their distal ends 7a, d. H. at the ends directed towards the free plug end 4a, they have a step-like raised nose 8. To insert the ribs 7, guide channels 9 are formed in the side walls of the openings 3, the depth of which corresponds to the height of the lugs 8. Thus, the flat connector 4 can be inserted with its end 4a into an associated opening 3 during assembly until the shoulders 6 stand on the base base 2 and the lugs 8 and part of the ribs 7 protrude on the underside of the base.

Den Zustand nach der Steckmontage des Flachsteckers 4 im Sokkelboden 2 zeigen die Figuren 2 und 3. Wie in der Schnittdarstellung von Figur 2 zu erkennen ist, ist mit der Rippe 7 das Material des Flachsteckers 4 etwa über die halbe Dicke nach außen geprägt. Für Flachstecker üblicher Abmessungen, also mit einer Dicke von etwa 0,8 bis 1,2 mm, hat sich eine Höhe der Rippe von grob annähernd der Hälfte der Materialdicke als zweckmäßig erwiesen, wobei die Nase entsprechend zusätzlich ausgeprägt wird. Es sind jedoch auch abweichende Verhältnisse denkbar, insbesondere bei anderen Abmessungen des Steckermaterials. Da der Führungskanal 9 zum Durchstecken der Nase 8 entsprechend tief sein muß, verbleibt zwischen der restlichen Rippe 7 und der Wand des Kanals 9 ein Luftspalt 10. Zum Verschluß dieses Luftspaltes ist am hinteren Ende 7b der Rippe eine Abdichtnase 11 angeformt, deren Höhe der der Nase 8 entspricht, so daß der Querschnitt des Führungskanals 9 ausgefüllt wird.FIGS. 2 and 3 show the state after the flat plug 4 has been plugged into the base 2 of the socket. As can be seen in the sectional view in FIG. 2, the material of the flat plug 4 is embossed with the rib 7 outward by about half the thickness. For flat plugs of conventional dimensions, that is to say with a thickness of approximately 0.8 to 1.2 mm, a height of the rib of roughly approximately half the material thickness has proven to be expedient, with the nose being additionally shaped accordingly. However, deviating conditions are also conceivable, in particular with different dimensions of the connector material. Since the guide channel 9 has to be correspondingly deep in order to insert the nose 8, it remains between the remaining rib 7 and the wall of the channel 9, an air gap 10. To close this air gap, a sealing nose 11 is formed at the rear end 7b of the rib, the height of which corresponds to that of the nose 8, so that the cross section of the guide channel 9 is filled.

Figur 3 zeigt den eingesteckten Flachstecker 4 in Draufsicht. Zu sehen sind die Führungskanäle 9 des Durchbruchs 3 sowie der Flachstecker 4 mit den nach einer Seite herausgeprägten Rippen 7. Wie in der Figur 3 außerdem gestrichelt angedeutet ist, könnte auch nach der anderen Seite eine Rippe 7' herausgeprägt und in einen Führungskanal 9' gesteckt werden.Figure 3 shows the inserted flat connector 4 in plan view. The guide channels 9 of the opening 3 and the flat plug 4 with the ribs 7 stamped out on one side can be seen. As is also indicated by dashed lines in FIG. 3, a rib 7 'could also be stamped out on the other side and inserted into a guide channel 9' will.

Die Fixierung des Flachsteckers ist in Figur 4 gezeigt. Der Flachstecker 4 sitzt mit einer Schulter 6 auf der Oberseite 2a des Sockelbodens 2 auf, nachdem er in Richtung des Pfeiles 12 in den Sockel eingesteckt wurde. Gegen Zurückdrücken während der Verformung wird der Flachstecker an seiner Oberkante 4b durch eine Gegenlage 13 abgestützt.The fixation of the tab connector is shown in Figure 4. The flat plug 4 is seated with a shoulder 6 on the upper side 2a of the base base 2 after it has been inserted into the base in the direction of the arrow 12. Against pushing back during the deformation, the flat connector is supported on its upper edge 4b by a counter support 13.

Mit einem Kerbstempel 14, der an der Nase 8 angreift, wird nunmehr diese Nase 8 mit dem anschließenden Teil der Rippe 7 vom Flachstecker 4 abgeschält, gestaucht und nach außen gebogen. Durch die Materialumformung entsteht eine Haltenase 17, die an der Unterseite 2b des Sockelbodens 2 anliegt, wobei ihre Wirkrichtung durch den Pfeil 18 angedeutet ist. Durch den Luftspalt 10 entstehen in dem Durchbruch praktisch keine Verspannung und kein Seitendruck, während der Flachstecker jedoch durch die Haltenase 17 formschlüssig am Sockel fixiert ist.With a notch stamp 14, which engages the nose 8, this nose 8 is now peeled off with the subsequent part of the rib 7 from the flat connector 4, compressed and bent outwards. The material deformation creates a retaining lug 17 which bears against the underside 2b of the base base 2, its direction of action being indicated by the arrow 18. Due to the air gap 10 there is practically no tension and no side pressure in the opening, but the tab is fixed in a form-fitting manner on the base by the retaining lug 17.
