Description

Die Erfindung betrifft einen Federsteckverbinder für gedruckte Schaltungen.The invention relates to a spring connector for printed circuits.

Es sind Federsteckverbinder bekannt, die auf einer gedruckte Schaltungen aufweisenden Platte sitzen und Öffnungen in der Platte zumindest mit Lötbeinen durchgreifen. Dabei ist ein Federsteckverbindertyp geeignet, z. B. ein Relais zu kontaktieren und zu haltern, das in die Stecköffnung des Federsteckverbinders gesteckt wird. Ein anderer Federsteckverbindertyp kann dagegen steckbare elektrische Flachsicherungselemente aufnehmen. Da ein Relais in der Regel dicker ist und andere Kontaktbedingungen (z. B. Stecktiefe) erfordert als eine elektrische Flachsicherung, sind bisher zwei verschiedene Steckverbindertypen für diese elektrischen Elemente erforderlich gewesen.Spring connectors are known, which sit on a printed circuit board and reach through openings in the board at least with soldering legs. A spring connector type is suitable, e.g. B. to contact and hold a relay that is inserted into the plug opening of the spring connector. Another type of spring connector, however, can accommodate pluggable electrical flat fuse elements. Since a relay is usually thicker and requires different contact conditions (e.g. insertion depth) than an electrical flat fuse, two different connector types have previously been required for these electrical elements.

Aufgabe der Erfindung ist, einen Federsteckverbinder zur Verfügung zu stellen, der in der Lage ist, gleichermaßen effektiv ein Relais oder eine Flachsicherung oder dergleichen unterschiedlicher elektrischer Elemente aufzunehmen und zu kontaktieren.The object of the invention is to provide a spring connector that is able to equally effectively a relay or a flat fuse or To record and contact the same different electrical elements.

Diese Aufgabe wird durch die Merkmale der Ansprüche gelöst. Anhand der Zeichnung wird die Erfindung beispielhaft näher erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf den Federsteckverbinder,
  • Fig. 2-einen mittigen Längsschnitt durch den Federsteckverbinder,
  • Fig. 3 eine Schmalseitenansicht des Federsteckverbinders.
This object is solved by the features of the claims. The invention is explained in more detail by way of example with reference to the drawing. Show it:
  • 1 is a plan view of the spring connector,
  • 2 shows a central longitudinal section through the spring connector,
  • Fig. 3 is a narrow side view of the spring connector.

Der neue Federsteckverbinder 1 durchgreift eine Öffnung 2 der Platte 3, die nur teilweise abgebildet ist und gedruckte Schaltungen aufweist (nicht dargestellt). Mit seinem Kontaktbereich überragt der Federsteckverbinder 1 die Oberfläche der Platte 3 wie dargestellt.The new spring connector 1 passes through an opening 2 of the plate 3, which is only partially shown and has printed circuits (not shown). With its contact area, the spring connector 1 projects beyond the surface of the plate 3 as shown.

Der Federsteckverbinder 1 ist einstückig ausgebildet und kastenförmig im Querschnitt' im wesentlichen rechteckig aufgebaut, wobei die Kastenform oben und unten offen ist und Steckbereiche bildet. Der Verbinder weist die Vorderwandung 4, die Rückwandung 5 sowie die Seitenwandungen 6 und 7 auf.The spring connector 1 is formed in one piece and has a box-shaped cross-section which is essentially rectangular, the box shape being open at the top and bottom and forming plug regions. The connector has the front wall 4, the rear wall 5 and the side walls 6 and 7.

An die Unterkanten 8 der im wesentlichen gleich ausgebildeten Vorder- und Rückwand 4,5, die von den Seitenwänden 6,7 her vorzugsweise mit einer Schräge 8 a beginnen, sind jeweils im Abstand y von den Seitenwandungen 6,7 zwei gleich geformte Kontaktfederarme 9 und 10 angebunden, die wiederum im Abstand x voneinander angeordnet sind. Jeder Kontaktfederarm 9, 10 ist länger als die Höhe des Verbinders 1 und - wie Fig. 3 zeigt - um etwa 170 einwärts umgebogen, so daß die sich gegenüberliegenden Federarme 9 oder 10 aufeinanderzulaufen, sich im oberen Drittel des Verbinders berühren und den Kontaktbereich 11 bilden. Vorzugsweise sind die Federarme im Kontaktbereich 11 im Querschnitt betrachtet ballig geformt (Fig. 1), so daß sich ein definierter, nahezu punktförmiger Kontaktbereich 11 ergibt.On the lower edges 8 of the substantially identical front and rear wall 4,5, which preferably start from the side walls 6,7 here with a bevel 8 a, are two equally shaped contact spring arms 9 and 9 each at a distance y from the side walls 6,7 10 connected, which in turn are arranged at a distance x from each other. Each contact spring arm 9, 10 is longer than the height of the connector 1 and - as shown in FIG. 3 - bent inwards by about 170 so that the spring arms 9 or 10 lying opposite one another run into contact with one another in the upper third of the connector and form the contact region 11. The spring arms in the contact area 11 are preferably spherical in cross section (FIG. 1), so that a defined, almost punctiform contact area 11 results.

Vom Kontaktbereich 11 nach oben sind die Federarme 9,10 von der Seite betrachtet (Fig. 3) bogenförmig auf die Wandungen 4,5 zugebogen und können sich gegen an der Oberkante der Wandungen 4,5 angeordnete Stege 12 abstützen, so daß die Federarme gegen Überbiegung geschützt sind. Dieser Überbiegeschutz wird dadurch gewährleistet, daß zwischen den Stegen 12 Lücken 13 vorgesehen sind, die von an der Endkante 14 der Federarme 9,10 verbliebenen Stegen 15, die schmaler sind als die Breite der Lücken 13 und der Federarme selbst, durchgriffen werden können, bis die Kanten 14 gegen die Stege 12 stoßen.From the contact area 11 upwards, the spring arms 9, 10 are viewed from the side (FIG. 3) in an arc towards the walls 4.5 and can be supported against webs 12 arranged on the upper edge of the walls 4.5, so that the spring arms against Overbend are protected. This overbend protection is ensured by the fact that gaps 13 are provided between the webs 12, which can be penetrated by webs 15 remaining on the end edge 14 of the spring arms 9, 10, which are narrower than the width of the gaps 13 and the spring arms themselves, until the edges 14 abut the webs 12.

Die die Wandungen 4 und 5 verbindende Seitenwandung 7 ist aus Gründen der Gewichtseinsparung und zur Erleichterung der Biegevorgänge bei der Herstellung des neuen Federsteckverbinders unterteilt in die Oberwandung 15 und die Unterwandung 16, wobei dazwischen eine relativ weite Aussparung 17 vorgesehen ist.The side wall 7 connecting the walls 4 and 5 is divided into the upper wall 15 and the lower wall 16 for reasons of weight saving and to facilitate the bending processes in the manufacture of the new spring connector, a relatively wide recess 17 being provided in between.

Die Seitenwandung 6 ist dagegen von oben bis unten durchgehend ausgeführt (Fig. 3) und an die Wandung 5, jedoch vorzugsweise lediglich über einen Scharniersteg 18, angebunden, der sich etwa im mittleren Bereich der Wandung 5 befindet. An der freien Endkante 19 ist zur Verriegelung der Kastenform des Federsteckverbinders eine von der Seite betrachtet T-förmige Lasche 20 angebunden, deren Steg 21 einen entsprechendbreiten und langen Ausschnitt 22 an der freien Endkante 23 der Wandung 4 durchragt, so daß die Endbereiche des T-Stücks 24 der Lasche 20 sich verriegelnd.von außen gegen die Wandung 4 abstützen können. Diese Verriegelung kann ggf. an geeigneten Kanten so verquetscht sein, daß sich eine Art Vernietung ergibt.The side wall 6, on the other hand, is continuous from top to bottom (FIG. 3) and is connected to the wall 5, but preferably only via a hinge web 18, which is approximately in the middle Area of the wall 5 is located. To lock the box shape of the spring connector, a T-shaped tab 20, viewed from the side, is connected to the free end edge 19, the web 21 of which extends through a correspondingly wide and long cutout 22 on the free end edge 23 of the wall 4, so that the end regions of the T- Piece 24 of the tab 20 locking. Able to support against the wall 4 from the outside. This locking can possibly be squeezed on suitable edges so that a kind of riveting results.

Die Verankerung des Federsteckverbinders in der Platte 3 kann auf jede beliebige Weise erfolgen. Zweckmäßigerweise sind dafür im Seitenwandungssteg 16 und gegenüberliegend in der Wandung 6 oberhalb der Platte 3 nach außen gedrückte Begrenzungssicken 25 vorgesehen, deren Unterkantenbereich auf der Platte 3 aufsitzen kann. Korrespondierend mit den Sicken 25 sind aus den Wandungen 4 und 5,vorzugsweise im Bereich des Zwischenraums x, Lappen 26 ausgeschnitten, die nach außen und unten abgeknickt sind, so daß ihre freien Endkanten auf der Plattenoberfläche aufsitzen können.The spring connector can be anchored in the plate 3 in any manner. Expediently there are provided in the side wall web 16 and on the opposite side in the wall 6 above the plate 3 outwardly delimiting beads 25, the lower edge area of which can rest on the plate 3. Corresponding to the beads 25, flaps 26 are cut out of the walls 4 and 5, preferably in the area of the space x, which are bent outwards and downwards so that their free end edges can rest on the plate surface.

Zudem sind Lötbeine 27 an der Unterkante 28 der Seitenwandungen 6 und 7 angeordnet, wobei die Seitenwandungen 6 und 7 vorzugsweise länger ausgeführt sind als die Wandungen 4 und 5 und in den Öffnungen 2 der Platte 3 stecken. Die Lötbeine 27 ragen mit der jeweiligen Wandung fluchtend aus der Öffnung 2 nach unten heraus (Fig. 2, rechte Seite) oder sind nach außen halbkreisförmig umgebogen, so daß sie sich gegen die Unterfläche der Platte 3 abstützen können, wodurch eine besonders zweckmäßige Verankerung des Federsteckverbinders 1 in der Platte 3 gewährleistet wird. Vorzugsweise sind - wie abgebildet - jeweils zwei Lötbeine 27 pro Seitenwandung 6 bzw. 7 im Seitenkantenbereich angeordnet.In addition, soldering legs 27 are arranged on the lower edge 28 of the side walls 6 and 7, the side walls 6 and 7 preferably being longer than the walls 4 and 5 and being inserted into the openings 2 in the plate 3. The solder legs 27 protrude in alignment with the respective wall from the opening 2 downwards (FIG. 2, right side) or are bent outwards in a semicircle so that they can be supported against the undersurface of the plate 3, thereby a particularly suitable anchoring of the Spring connector 1 is guaranteed in the plate 3. Preferably - as shown - two solder legs 27 per side wall 6 and 7 arranged in the side edge area.

Der neue Federsteckverbinder ist zum Stecken sowohl eines Relais' als auch einer Flachsicherung oder dergleichen unterschiedlicher elektrischer Elemente geeignet, weil er einen kurzen Steckweg oben und einen langen Steckweg von unten bietet. Relais werden daher vorzugsweise von unten, also vom Lötbeinbereich, und Sicherungen von oben gesteckt. Die besonders große Länge der Federarme gewährleistet eine sehr elastische Federkraft. Im Zusammenwirken mit dem Überbiegeschutz können elektrische Elemente mit erheblichen Dickentoleranzen sicher gesteckt, gehaltert und kontaktiert werden.The new spring connector is suitable for plugging in both a relay and a flat fuse or the like of different electrical elements because it offers a short plug-in path at the top and a long plug-in path from below. Relays are therefore preferably inserted from below, i.e. from the soldering leg area, and fuses from above. The particularly large length of the spring arms ensures a very elastic spring force. In conjunction with the overbend protection, electrical elements with considerable thickness tolerances can be securely inserted, held and contacted.

Im Rahmen der Erfindung liegt es, die Federarme 9,10 bei etwa gleicher Formgebung an die Stege 12 anzubinden und nach unten zu führen, wobei der Überbiegeschutz im Bereich der Lappen 26 vorgesehen ist und der Kontaktbereich ebenfalls in diesen unteren Bereich verlegt wird. Die umgekehrte Version der Federarme hat den Vorteil, daß sowohl die Relais als auch die Sicherungen von unten gesteckt werden können. Diese Ausführungsform der Erfindung ist nicht gesondert abgebildet worden, weil sie ohne weiteres verständlich ist.It is within the scope of the invention to connect the spring arms 9, 10 with approximately the same shape to the webs 12 and to guide them downward, the overbend protection being provided in the area of the tabs 26 and the contact area likewise being moved to this lower area. The reverse version of the spring arms has the advantage that both the relays and the fuses can be inserted from below. This embodiment of the invention has not been shown separately because it is easy to understand.
