Abstract

A mount secures a high-wattage miniature relay having a plurality of high-amp connection prongs and of control-voltage connection prongs to high-amp wires and to a circuit board. The mount has a dielectric body constructed to fit on the board and formed with respective seats for the prongs, and respective high-amp passages each having an outer end opening outward and an inner end opening at the seat for the respective high-amp prong. Respective low-amp conductors extend from the seats of the control-voltage prongs and engage in the board. Respective metallic high-amp conductors extend in the passages and have inner ends constituted as sockets for the respective high-amp prongs and outer ends constituted as connectors for the respective high-amp wires. The high-amp conductors are unitary with the respective sockets. In addition they can be unitary with the respective connectors. The connectors can be wire clips provided, like the connectors on circuit breakers, with respective wire-clamping screws.

Description

Die Erfindung betrifft eine Fassung für ein Miniaturrelais, mit einem Isolierstoffkörper und darin eingebetteten Steuerstrom- und Schaltstrom-Kontakten einerseits zur Verbindung der Steuerstrom-Anschlussstifte des Relais mit einer Leiterplatte und andererseits zum Anschluss der Schaltstrom-Anschlussstifte des Relais.The invention relates to a version for a miniature relay, with an insulating body and embedded control current and switching current contacts on the one hand for connecting the control current pins of the relay to a circuit board and on the other hand for connecting the switching current pins of the relay.

Für Miniaturrelais zur Verwendung auf einer gedruckten Leiterplatte sind Steckfassungen bekannt, in die Kontakte eingebettet sind, die mit jeweils einen stiftförmigen Füsschen aus dem Isolierstoffkörper heraustreten und die am anderen Ende Steckaufnahmen für die Anschlussstifte des Relais besitzen. Die Lötfüsschen werden sämtlich mit entsprechenden Leiterbahnen der Leiterplatte verlötet, wie dies allgemein mit Lötfüssen elektronischer Bauteile geschieht. Wegen der genormten Abmessungen der Miniaturrelais und des Rastermasses des Stiftabstandes sind derartige Fassungen nur für Miniaturrelais geeignet und bestimmt, bei denen der Steuerstrom und auch der Schaltstrom gering ist, während bei hohen Schaltströmen die elektrische Sicherheit der Schaltung nicht mehr gewährleistet ist, insbesondere aufgrund der nicht mehr einhaltbaren Mindestabstände für die Kriech- und Luftstrecken.For miniature relays for use on a printed circuit board, sockets are known, in which contacts are embedded, which come out of the insulating material body with a pin-shaped foot and which have plug receptacles for the connecting pins of the relay at the other end. The soldering feet are all soldered to corresponding conductor tracks on the circuit board, as is generally the case with soldering feet of electronic components. Because of the standardized dimensions of the miniature relays and the grid spacing of the pin spacing, such sockets are only suitable and intended for miniature relays in which the control current and the switching current are low, while the electrical safety of the circuit is no longer guaranteed at high switching currents, in particular because of the no more maintainable minimum clearances for creepage distances and clearances.

Um an einer Leiterplatte auch Miniaturrelais mit Schaltstrom von bis zu 16 A betreiben zu können, hat man sich bislang mit einer den Sicherheitsanforderungen ebenfalls nicht genügenden Sonderanordnung beholfen. Dabei hat man am Rand der Leiterplatte eine Anschlussklemme zur Befestigung der elektrischen Leiter angeordnet und die Anschlussklemmen über breite Leiterbahnen mit der Fassung für das Miniaturrelais verbunden. Hierzu hat man auch Leiterplatten mit Doppelkaschierungen benutzt, um die unterschiedlich starken Ströme räumlich voneinander zu trennen. Dass diese Hilfslösung, abgesehen davon, dass sie den Sicherheitsanforderungen nicht entspricht, in hohem Masse nachteilig ist, versteht sich von selbst.In order to be able to operate miniature relays with a switching current of up to 16 A on a circuit board, a special arrangement that does not meet the safety requirements has been used so far. A connection terminal for attaching the electrical conductors has been arranged at the edge of the circuit board and the connection terminals have been connected to the socket for the miniature relay via wide conductor tracks. For this purpose, circuit boards with double laminations have also been used to spatially separate the currents of different strengths. It goes without saying that this auxiliary solution, apart from the fact that it does not meet the security requirements, is highly disadvantageous.

Der Erfindung liegt die Aufgabe zugrunde, eine Fassung für ein Miniaturrelais verfügbar zu machen, welches im Aufbau einfach, in der Handhabung problemlos und für hohe Schaltströme (bis 16 Ampere) bei voller Einhaltung aller elektrischer Sicherheitsbestimmungen, verwendbar ist.The invention has for its object to provide a version for a miniature relay, which is simple in construction, easy to use and for high switching currents (up to 16 amps) with full compliance with all electrical safety regulations.

Nach der Erfindung wird diese Aufgabe dadurch gelöst, dass dem Isolierstoffkörper eine besondere Kammeranordnung zugeordnet ist, in der Steck-oder Schraub-Anschlussklemmen für den Schaltstrom führende Kabel oder Steckervorgesehen sind und die durch metallische Brücken innerhalb des Isolierkörpers mit den Schaltstrom-Kontakten verbunden sind.According to the invention, this object is achieved in that a special chamber arrangement is assigned to the insulating body, in which plug or screw connection terminals for the switching current carrying cables or plugs are provided and which are connected to the switching current contacts by means of metallic bridges within the insulating body.

Dadurch wird sichergestellt, dass zur Leitung des hohen elektrischen Stromes zwischen den Kabeln und den Kontaktstiften des Miniaturrelais lediglich innerhalb der Fassung angeordnete Metallteile dienen, während die Kaschierung der Leiterbahn nur noch die niedrigen Ströme zu führen hat. Damit ist die elektrische Sicherheit insbesondere dadurch gewährleistet, dass der Isolierstoffkörper selbst die hohen Ströme von den niedrigen des Ansteuerstromkreises wirksam isoliert und für die Einhaltung der erforderlichen Luft- und Kriechstrecken sorgt. Insbesondere, wenn die Wände der besonderen Kammer stoffschlüssig mit Wänden des Isolierstoffkörpers verbunden sind, die Kammer mithin als Erweiterung des Isolierstoffkörpers ausgebildet ist, ergibt sich ein einstückiges und mithin einteilig zu handhabbares Bauteil für die Fassung, welches vollständig vorgefertigt leicht zu handhaben ist.This ensures that only metal parts arranged within the socket serve to conduct the high electrical current between the cables and the contact pins of the miniature relay, while the lamination of the conductor track only has to carry the low currents. This ensures electrical safety, in particular, in that the insulating body effectively isolates even the high currents from the low ones of the control circuit and ensures that the required air and creepage distances are maintained. In particular, if the walls of the special chamber are integrally connected to the walls of the insulating body, the chamber is therefore designed as an extension of the insulating body, there is a one-piece and therefore one-piece component for the socket, which is completely prefabricated and easy to handle.

Die erwähnten Brücken können einstückige Bestandteile der Kontakte und darüber hinaus einstükkige Bestandteile der Anschlussklemmen sein. Man gelangt im Idealfall dazu, dass die Brücken an einem Ende die Anschlussklemme und am anderen Ende die Kontaktaufnahmen für die Anschlussstifte des Miniaturrelais in einstückiger Weise bereitstellen.The bridges mentioned can be one-piece components of the contacts and moreover one-piece components of the connection terminals. Ideally, the bridges provide the terminal at one end and the contacts for the connector pins of the miniature relay at the other end in one piece.

Bei Verwendung einer Klotzklemme ist es von Vorteil, wenn die Brücke eine Einlege-oder Einrastlasche zur Verbindung mit dem Klotz einer als Klotzklemme ausgebildeten Schraub-Anschlussklemme aufweist. Bei der Montage der Fassung können die gegebenenfalls die Kontakte selbst aufweisende Brücken auf einfache Weise mit der Klotzklemme verbunden werden.When using a block clamp, it is advantageous if the bridge has an insertion or snap-in tab for connection to the block of a screw connection clamp designed as a block clamp. When assembling the socket, the bridges, which may have the contacts themselves, can be connected in a simple manner to the block clamp.

Von weiterem Vorteil ist eine Ausgestaltung, die dadurch gekennzeichnet ist, dass die besondere Kammeranordnung mindestens eine seitlich offene Tasche aufweist, von deren Öffnungsseite her die Kontakte und die Klemmen einsteckbar sind.A further advantage is an embodiment which is characterized in that the special chamber arrangement has at least one laterally open pocket, from the opening side of which the contacts and the terminals can be inserted.

Die besondere Kammeranordnung ist vorzugsweise an einer Schmallängsseite der Fassung angeordnet, was namentlich den Vorteil der kürzesten Verbindung zwischen den die Kontaktstifte des Relais aufnehmenden Kontakten und den Anschlussklemmen besitzt.The special chamber arrangement is preferably arranged on a narrow longitudinal side of the socket, which in particular has the advantage of the shortest connection between the contacts receiving the contact pins of the relay and the connection terminals.

Zur sicheren Festlegung auf einer Leiterplatte kann der Isolierstoffkörper in einem den Steuerstrom-Kontakten abgelegenen Bereich mit elektrisch funktionslosen Lötstützfüssen versehen sein, zumal sich die neue Fassung von der bekannten Fassung dadurch unterscheidet, dass lediglich noch die Steuerstromkontakte über Lötfüsschen verfügen, während die Schaltstromkontakte vollständig im Isolierstoffkörper der Fassung integriert sind.For secure fixing on a printed circuit board, the insulating body can be provided with electrically non-functional soldering support feet in an area remote from the control current contacts, especially since the new version differs from the known version in that only the control current contacts have soldering feet, while the switching current contacts are completely in the Insulating body of the socket are integrated.

Die Erfindung wird nachfolgend anhand zweier in den Zeichnungen dargestellter Ausführungsbeispiele näher erläutert. In den Zeichnungen zeigen:

  • Fig. 1 eine Aufsicht auf eine mit einer Steckanschlussklemme versehenen Fassung,
  • Fig. 2 einen Querschnitt gemäss Schnittlinie 11-11 in Fig. 1,
  • Fig. 3 eine im Teilschnitt wiedergegebene Ansicht in Richtung des Pfeiles 111 in Fig. 1,
  • Fig. 4 einen Teil-Querschnitt gemäss Schnittlinie IV-IV in Fig. 3.
The invention is explained in more detail below with reference to two exemplary embodiments shown in the drawings. The drawings show:
  • 1 is a plan view of a socket provided with a plug-in terminal,
  • 2 shows a cross section along section line 11-11 in FIG. 1,
  • 3 shows a view in partial section in the direction of arrow 111 in FIG. 1,
  • 4 shows a partial cross section according to section line IV-IV in FIG. 3.

Die Fig. 5 bis 8 zeigen in gleicher Darstellung entsprechend den Fig. 1 bis 4 eine Fassung mit einer Schraub-Anschlussklemme.5 to 8 show in the same representation corresponding to FIGS. 1 to 4 a socket with a screw terminal.

Die Fassung besitzt einen Isolierstoffkörper 10 aus Kunststoff von in der Aufsicht etwa L-förmiger Gestalt mit einem langen Schenkel 11 und einem kürzeren Schenkel 12, der an einer Längsseite 13 des ersten Schenkels 11 angeordnet ist. Die Deckseite 14 der Isolierstoffkörperschenkels 11 ist mit je paarweise angeordneten Einstecköffnungen 15 bis 18 versehen, die zum Einführen der Relais-Kontaktstifte dienen. Die Einstecköffnungen 15 sind dabei dem Ansteuerstromkreis des Relais zugeordnet und die Einstecköffnungspaare 16 bis 18 dem Schaltstromkreis, wobei z.B. einem Wechselkontakt die Einstecköffnungen 17, einem Schliesskontakt die Einstecköffnungen 17 und einem Öffnerkontakt die Einstecköffnungen 18 zugeordnet sein kann.The socket has an insulating plastic body 10 of approximately L-shaped shape in plan view with a long leg 11 and a shorter leg 12, which is arranged on a long side 13 of the first leg 11. The cover side 14 of the insulating body limbs 11 is provided with insertion openings 15 to 18 arranged in pairs provided that serve to insert the relay contact pins. The plug-in openings 15 are assigned to the control circuit of the relay and the plug-in pair of openings 16 to 18 to the switching circuit, it being possible, for example, to assign the plug-in openings 17 to a changeover contact, the plug-in openings 17 to a make contact, and the plug-in openings 18 to a break contact.

Im Bereich jeder Einstecköffnung 15 befindet sich ein Kontakt bzw. eine Kontaktfeder 19 im Isolierstoffgehäuse 10 eingebettet, die eine Kontaktstiftaufnahme 20 sowie am anderen Ende einen aus dem Isolierstoffkörper 10 heraustretenden Lötfuss 21 zur Verbindung mit einer Leiterplatte aufweist. Damit dient der Kontakt der elektrischen Verbindung der Leiterbahn, an der der Lötfuss 21 befestigt wird, mit dem betreffenden Kontaktstift des - nicht dargestellten - Miniaturrelais.In the area of each insertion opening 15 there is a contact or a contact spring 19 embedded in the insulating material housing 10, which has a contact pin receptacle 20 and at the other end a solder foot 21 emerging from the insulating material body 10 for connection to a printed circuit board. The contact thus serves for the electrical connection of the conductor track, to which the soldering foot 21 is fastened, with the relevant contact pin of the miniature relay (not shown).

Ausser den beiden Lötfüsschen 21 der Kontakte 19 treten aus dem Isolierstoffkörper 10 der erfindungsgemässen Fassung keine weiteren zur Stromführung bestimmten Metallteile aus. Die mit 22 bezeichneten Lötstützfüsschen, die im den Kontakten 19 abgelegenen Bereich des Isolierstoffkörpers 10 von der Unterseite her in diesen eingesteckt sind, sind elektrisch funktionslos und dienen nur der zusätzlichen Fixierung auf der Leiterplatte. Beim Ausführungsbeispiel stehen die Lötstützfüsschen 22 über einen Steg 23 miteinander in stoffschlüssiger Verbindung, wodurch sie gemeinsam handhabbar und leichter in den Isolierstoffkörper 10 einsetzbar sind.Apart from the two soldering feet 21 of the contacts 19, no further metal parts intended for carrying current emerge from the insulating body 10 of the socket according to the invention. The soldering support feet designated with 22, which are inserted into the area of the insulating body 10 remote from the contacts 19 in the contacts 19, are electrically non-functional and serve only for additional fixing on the printed circuit board. In the exemplary embodiment, the soldering support feet 22 are connected to one another via a web 23, as a result of which they can be handled together and are easier to insert into the insulating material body 10.

Der kleinere L-Schenkel 12 des Isolierstoffkörpers 10 ist an den Hauptschenkel 1 als besondere Kammeranordnung seitlich angesetzt und besitzt drei zur Seite hin offene Kammerhohlräume 24 bis 26. Jede dieser Kammern 24, 25, 26 liegt in Verlängerung einer im Hauptschenkel 11 befindlichen und den Öffnungen 16 bzw. 17 bzw. 18 zugeordneten Kammer (z.B. die Kammer 27). Jede der Kammern (z.B. 27) im Hauptschenkel 11 nimmt einen Doppelkontakt 28 mit zwei Kontaktstiftaufnahmen 29 für die zugehörigen Relaiskontaktstifte auf.The smaller L-leg 12 of the insulating body 10 is laterally attached to the main leg 1 as a special chamber arrangement and has three chamber cavities 24 to 26 which are open to the side. Each of these chambers 24, 25, 26 lies in the extension of one located in the main leg 11 and the openings 16 or 17 or 18 associated chamber (eg chamber 27). Each of the chambers (e.g. 27) in the main leg 11 receives a double contact 28 with two contact pin receptacles 29 for the associated relay contact pins.

In jeder der Kammern 24 bis 26 befindet sich beim Ausführungsbeispiel nach den Fig. 1 bis 4 eine Steckanschlussklemme 30 mit Zungen 31, auf die in üblicher Weise z.B. an den Enden von den hohen Strom führenden Kabeln angeklemmte Kabelschuhe aufgeschoben werden können. Der Steckanschluss 30 ist mit dem Doppelkontakt 28 einstückig durch eine Brücke 32 stromleitend verbunden. Somit kann der jeweils einstückige Kontaktsatz 28/29/30/32 von der offenen Aussenseite 33 einer jeden Kammer (z.B. 24) in die Kammeranordnung 24, 27 eingesteckt werden. Durch Press- oder Klemmsitz kann ohne besondere Befestigungsmittel die unverlierbare Halterung dieses Kontaktsatzes im Isolierstoffkörper 10 erreicht werden.In the embodiment according to FIGS. 1 to 4, in each of the chambers 24 to 26 there is a plug-in connection terminal 30 with tongues 31, in the usual manner e.g. cable lugs clamped at the ends of the high current cables can be pushed on. The plug connection 30 is connected in one piece to the double contact 28 in a current-conducting manner by a bridge 32. Thus, the one-piece contact set 28/29/30/32 can be inserted into the chamber arrangement 24, 27 from the open outside 33 of each chamber (e.g. 24). The captive mounting of this contact set in the insulating material body 10 can be achieved by means of a press or clamp fit without special fastening means.

Die Fassung des zweiten Ausführungsbeispiels nach den Fig. 5 bis 8 unterscheidet sich von dem ersten nach Fig. 1 bis 4 im wesentlichen dadurch, dass,hier anstelle des Steckanschlusses 30 eine Schraubanschlussklemme 40 zum Anschluss der den hohen Strom führenden Kabel besitzt. Die Schraubanschlussklemme 40 ist ebenfalls in einem kürzeren L-Schenkel 12 seitlich neben dem Hauptschenkel 11 des Isolierstoffkörpers 10 und werkstoffeinheitlich mit diesem verbunden vorgesehen. Die Schraubanschlussklemme 40 ist als Klotzklemme üblicher Bauart ausgebildet und weist in bekannter Weise einen Klemmenklotz 41, einen Drahtschutz 42 sowie eine Klemmschraube 43 auf. Die Brücke 44 zur leitenden Verbindung der Schraubanschlussklemme 40 und dem Doppelkontakt 28 ist hier als Einlegelasche ausgebildet. Sie besitzt eine krallenförmige 180°-Kröpfung 46 zum Umgreifen der nach aussen gerichteten Bodenseitenkante 45 des Klemmenklotzes 41 sowie an der anderen Bodenseitenkante 47 eine aus dem Streifen der Brücke 44 herausgeprägte Federzunge 48. Damit kann die Brücke 44 mit dem Klemmenklotz 41 unverlierbar verrastet werden.The version of the second exemplary embodiment according to FIGS. 5 to 8 differs from the first according to FIGS. 1 to 4 essentially in that here, instead of the plug connection 30, has a screw terminal 40 for connecting the cables carrying the high current. The screw terminal 40 is also provided in a shorter L-leg 12 laterally next to the main leg 11 of the insulating material body 10 and connected to the same in the same material. The screw connection terminal 40 is designed as a block clamp of a conventional type and has a clamp block 41, a wire protection 42 and a clamp screw 43 in a known manner. The bridge 44 for the conductive connection of the screw terminal 40 and the double contact 28 is designed here as an insertion tab. It has a claw-shaped 180 ° offset 46 for gripping around the outwardly directed bottom side edge 45 of the terminal block 41 and, on the other bottom side edge 47, a spring tongue 48 stamped out of the strip of the bridge 44. The bridge 44 can thus be locked captively with the terminal block 41.

Mit dem Boden des Isolierstoffkörpers 10 auf eine Leiterplatte aufgesetzt und über die Lötfüsse 21 bzw. 22 auf der Leiterplatte elektrisch sowie mechanisch verbunden, ist der Anschluss der den Leistungsstrom führenden Zuleitungen über die Steckanschlussklemme 30 oder die Schraubanschlussklemme 40 auf leichte Weise möglich, wobei - wie ersichtlich - alle die hohen Schaltströme führenden Metallteile vollständig innerhalb des Isolierstoffkörpers, von diesem umkapselt, aufgenommen sind. Somit sind auch die notwendigen Kriech-und Luftstrecken zwischen den Leiterbahnen und den die hohen Schaltströme führenden Teilen eingehalten. Wie weiterhin ersichtlich ist, kann der Isolierstoffkörper 10 in einfacher Weise als einstückiger Spritzgiessartikel aus Kunststoff hergestellt werden.With the bottom of the insulating material body 10 placed on a printed circuit board and electrically and mechanically connected via the soldering feet 21 or 22 on the printed circuit board, the connection of the leads carrying the power current is easily possible via the plug connection terminal 30 or the screw connection terminal 40, whereby - as can be seen - all the metal parts carrying the high switching currents are completely accommodated within the insulating body, encapsulated by the latter. The necessary creepage distances and clearances between the conductor tracks and the parts carrying the high switching currents are thus also complied with. As can also be seen, the insulating body 10 can be produced in a simple manner as a one-piece injection molded article made of plastic.

Die Zeichnungen veranschaulichen die Miniaturrelais-Fassung etwa im Massstab von 4 : 1.The drawings illustrate the miniature relay socket on a scale of approximately 4: 1.
