Abstract

The multiple pin connector for a printed circuit board has a body (5) to which the ends of the wires (L) are connetected. Each wire is clamped by a sleeve mounted underneath a sloping part of the body. This sleeve terminates in a strip (F) bent over double and held in contact against the surface of the plate (LP), acting as a spring. Immediately behind the contact zone, are slotted holes through the plate, through which are inserted hooked members (HF) projecting downwards and forming part of the body. The locking action is completed by an extension (UL) of the body, which is an inverted U shape in cross-section with a hooked nose (AF) which locks under the edge of another slot (A2) in the printed circuit.

Description

Andruckverbinder für LeiterplattenanschlüssePressure connector for circuit board connections

Die Erfindung betrifft einen Andruckverbinder für Leiterplattenanschlüsse, mit dem an beliebiger Stelle einer Leiterplatte Verbindungen zu anderen außerhalb der Leiterplatte befindlichen Baugruppen herstellbar sind.The invention relates to a pressure connector for circuit board connections, with the anywhere on a circuit board connections to other outside assemblies located on the printed circuit board can be produced.

Andruckverbinder werden in der Leiterplattentechnik verwendet, um Leiterplatten, die nicht in einem Stück herstellbar sind, miteinander zu verbinden. Auch wenn nachträgliche Erweiterungen, z.B. bei Koppelfeldern, vorgenommen werden sollen, werden Andruckverbinder verwendet.Pressure connectors are used in circuit board technology to To connect circuit boards that cannot be manufactured in one piece with one another. Even if subsequent expansions are made, e.g. in the case of switching matrices pressure connectors are used.

Andruckverbinder können auch benutzt werden, um Eabelanschlüsse mit der Leiterplatte zu verbinden. Gegenüber anderen Verbindungsmöglichkeiten hat der Andauckverbinder den Vorteil, daß auf der Leiterplatte selbst keine Kontaktelemente bestückt werden müssen.Pressure connectors can also be used to make cable connections with to connect the circuit board. Compared to other connection options, the Andauckverbindungen the advantage that there are no contact elements on the circuit board itself need to be populated.

Die Kontaktfedern eines Andruckverbinders werden direkt mit den als Leiterbahn ausgeführten Sontaktflächen in Berührung gebracht.The contact springs of a pressure connector are directly connected to the as Conducted contact surfaces brought into contact.

Bekannte Andruckverbinder bestehen aus mehreren Teilen. Das die Kontaktfeldern tragende Teil wird mit Schrauben an den zu verbindenden Leiterplatten befestigt, wobei der notwendige Kontaktdruck entsteht.Known pressure connectors consist of several parts. That the contact fields load-bearing part is attached to the printed circuit boards to be connected with screws, whereby the necessary contact pressure is created.

Um den Kontaktdruck gleichmäßig auf allen Federn zu bewirken, sind meistens außerdem noch Metallbügel oder Schienen notwendig, die bei der Befestigung anzubringen sind. Dazu gehören noch Kleinteile wie Schrauben, Muttern, Unterlegscheiben u.ä.In order to produce the contact pressure evenly on all springs, are usually also metal brackets or rails are necessary for the attachment are to be attached. This also includes small parts such as screws, nuts and washers etc.

Solche Anordnungen zum Verbinden von Koppelfeld-Leiterplatten sind unter dem Begriff "Klemmverbinder" beschrieben und abgebildet auf den Seiten 11 und 12 der TN-Nachnchten von 1967 Heft 67. Hier ist deutlich erkennbar, wie die zur Kontaktgabe erforderlichen Polstreifen am Rand der Leiterplatten angeordnet sind. Diese Andurckverbinder sind waagerecht und senkrecht zwischen den einzelnen Koppelfeldleiterplatten festgeschraubt.Such arrangements for connecting switching matrix circuit boards are Described under the term "clamp connector" and shown on pages 11 and 12 of the TN Nachnchten from 1967 issue 67. Here you can clearly see how the Pole strips required for making contact are arranged on the edge of the circuit boards are. These pressure connectors are horizontal and vertical between the individual Coupling circuit boards screwed tight.

Da diese bekannten Andruckverbinder aus vielen eilen bestehen und in relativ großen Stückzahlen in einer anlage benötigt werden, ist der materielle Aufwand erheblich. Die ziemlich komplizierte Montage erfordert außerdem einen großen lohnintensiven Zeitaufwand.Since these known pressure connectors consist of many parts and required in relatively large numbers in a plant is the material one Considerable effort. The rather complicated assembly also requires a large one wage-intensive expenditure of time.

Aufgabe der Erfindung ist es, einen Andruckverbinder vorzustellen, der aus wenigen eilen besteht und sehr einfach zu montieren ist, um eine preiswerte VerbIndungstechnik zu schaffen.The object of the invention is to present a pressure connector, which consists of a few parts and is very easy to assemble, making it an inexpensive one To create connection technology.

Die Aufgabe wird dadurch gelöst, daß die den Kontakt mit der Leiterplatte herstellenden blattförmigen Andurckfedern in der Unterseite eines Kunststoffgehäuses eingebettet sind, und dieses Kunststoffgehäuse mittels in entsprechende Aussparungen der Lei- terplatte eingreifenden Schnappelementen lösbar auf der Leiterplatte befestigbar ist.The object is achieved in that the contact with the circuit board producing leaf-shaped pressure springs in the underside of a plastic housing are embedded, and this plastic housing means in corresponding recesses the line terplatte engaging snap elements releasably on the Circuit board can be fastened.

Mit dieser Ausführung wird erreicht, daß der Andruckverbinder neben den Kontaktfedern nur aus einem einzigen Teil besteht. Besondere Befestigungsteile sind nicht notwendig. Durch die mit dem Gehäuse eine Einheit bildenden Schnappelemente ist eine einfache und schnelle Montage gegeben. Die an der Leiterplatte notwendigen Anordnungen wie Kontaktflächen und Aussparungen unterscheiden sich nicht von den bei bekannten Andruckverbhndern angewendeten Versionen, so daB keine Verteuerung entsteht. Diese Andruckverbinder können an beliebiger Stelle auf der Leiterplatte angeordnet werden. Sie können für eine Kabelverbindung benutzt werden oder auch mit einer anderen Leiterplatte direkt in Verbindung stehen. Ein besonderer Vorteil besteht auch darin, daß der Andrnckverbinder sehr leicht lösbar ist. Das ist besonders nützlich, wenn bei einer Störung Signaladern getrennt werden müssen.With this design it is achieved that the pressure connector next to the contact springs consists of only one part. Special fasteners are not necessary. By the snap elements forming a unit with the housing assembly is quick and easy. The ones necessary on the circuit board Arrangements such as contact surfaces and recesses do not differ from the Versions used with known pressure connectors, so that no increase in price arises. These pressure connectors can be placed anywhere on the circuit board to be ordered. They can be used for a wired connection or also are in direct contact with another printed circuit board. A particular advantage also consists in the fact that the pressure connector is very easy to detach. This is special useful if signal wires have to be disconnected in the event of a fault.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand von Zeichnungen näher erläutert.An exemplary embodiment of the invention is described below with reference to FIG Drawings explained in more detail.

Es zeigt: Fig.1 Den Kunststoffkörper des Andruckverbinders mit Andruckfedern von unten gesehen Fig.2 Die Seitenansicht des in die Leiterplatte eingerasteten Andanckverbinders Fig*3 Den Aufnahmeplatz für einen Andruckverbinder auf der Leiterplatte Das hier gezeigte Ausführungsbeispiel stellt einen Andruckverbinder dar, mit dem flexible Leitungen L mit der Leiterplatte verbunden werden können. Das in Fig.1 dargestellte Kunststoffteil E enthält acht Kammern für die Aufnahme der AndruckSedern F. Die hakenförmigen Ansätze sind fest (HS) und federnd (AF) ausgebildet und in ihrer Form in Fig.2 erkennbar.It shows: Fig. 1 The plastic body of the pressure connector with pressure springs seen from below Fig.2 The side view of the latched into the circuit board Andanckverbinders Fig * 3 The location for a pressure connector on the circuit board The embodiment shown here represents a pressure connector with which flexible lines L can be connected to the circuit board. The in Fig.1 Plastic part E shown contains eight chambers for the recording der AnruckSedern F. The hook-shaped extensions are fixed (HS) and resilient (AF) and their shape can be seen in FIG.

Beim Andrücken der Kontaktfedern F werden zunächst die die Leiterplatte LP hintergreifenden festen Ansätze HF in die Aussparungen Al eingeführt. Sodann wird auch der federnde Ansatz AS in die Aussparung A2 eingedrückt. Dabei wird der gesamte Andruckverbinder durch die Federkraft des gebogenen Teiles UL und die Ausgestaltung der Hakenform AF mechanisch so verriegelt, daß der erforderliche Eontaktdruck entsteht.When the contact springs F are pressed on, the circuit board is first LP rear-reaching fixed approaches HF introduced into the recesses Al. Then the resilient extension AS is also pressed into the recess A2. The entire pressure connector by the spring force of the bent part UL and the design the hook shape AF is mechanically locked in such a way that the required contact pressure is created.

Die Fig.3 zeigt die Ausgestaltung der Leiterplatte an der Stelle, wo ein Andruckverbinder aufgebracht werden soll. Die Aussparungen Al und A2 sird so zu den Kontaktflächen KF angeordnet, daß die Andruckfedern beim Einsetzen des Andruckverbinders die Eontaktflächen zwangsläufig genau treffen. Die Kontaktflächen werden zusammen mit den Leiterbahnen LB hergestellt und benötigen keine besondere Behandlung.Fig. 3 shows the design of the circuit board at the point where a pressure connector is to be applied. The recesses A1 and A2 are so arranged to the contact surfaces KF that the pressure springs when inserting the Pressure connector necessarily meet the contact surfaces exactly. The contact areas are produced together with the conductor tracks LB and do not require any special ones Treatment.

Sie sind lediglich etwas breit ausgeführte Leiterbahnen.They are just a bit broad conductor tracks.

Der erfindungsgemäße Andruckverbinder ist somit ein einfach zu montierendes Teil, mit dem auf preiswerte Art Verbindungen von und zu Leiterplatten hergestellt werden können.The pressure connector according to the invention is therefore easy to assemble Part that makes connections to and from printed circuit boards in an inexpensive way can be.
