Description

Die Erfindung betrifft ein selbständig feststehendes Anschlußelement zur Herstellung eines löt-, schraub- und abisolierfreien Kontaktes, insbesondere für die Fernmeldetechnik, und bezweckt die Schaffung einer solchen Vorrichtung, die entsprechend ihrem hohen Bedarf kostengünstig als Massenartikel herstellbar ist.The invention relates to an independently fixed connection element for producing a solder-free, screw-free and stripping-free contact, in particular for telecommunications technology, and aims to create such a device which can be mass-produced inexpensively in accordance with its high requirements.

Es sind zur Herstellung von löt-, schraub- und abisolierfreien Kontaktierungen mit isolierten Kabel- oder Schaltadern aus der DE-B2-2610461 und der DE-A1-2804478 Anschlußelemente bekannt, deren blattförmigen federnden Kontaktteile sich an isolierenden Kunststoffkörpern abstützen, wobei die Kunststoffteile des weiteren die Aufgabe haben, über angeformte Klemmrippen die Kontaktstellen von jeglicher Aderbewegung freizuhalten.There are known from the DE-B2-2610461 and DE-A1-2804478 connecting elements whose leaf-shaped resilient contact parts are supported on insulating plastic bodies, the plastic parts of which are known for the production of solder-free, screw-free and stripping-free contacts with insulated cable or switching wires further have the task of keeping the contact points free of any wire movement via molded-on clamping ribs.

Dieses Abstützen wird jedoch dann unmöglich, wenn derartige Anschlußelemente auf engstem Raum, z. B. auf Leiterplatten, verwendet werden sollen.However, this support is impossible if such connection elements in a confined space, for. B. on circuit boards to be used.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Anschlußelement der eingangs genannten Art zu entwickeln, das auf engstem Raum, z. B. auf Leiterplatten, verwendbar ist.The invention is therefore based on the object to develop a connection element of the type mentioned that in a confined space, for. B. on circuit boards, can be used.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Anschlußelement z-förmig ausgebildet und aus einem unter ca. 45° zur Aderachse eines einzuführenden Drahtes stehenden Kontaktierungsteil sowie aus zwei senkrecht zur Drahtachse liegenden Klemmteilen aufgebaut ist, wobei im unteren Bereich des Anschlußelementes Steckstifte angeordnet sind.This object is achieved in that the connecting element is z-shaped and is constructed from a contacting part at approximately 45 ° to the wire axis of a wire to be inserted and from two clamping parts perpendicular to the wire axis, pins being arranged in the lower region of the connecting element.

Durch diese Lösung werden zwei wesentliche Vorteile erreicht :

  • 1. Durch die z-förmige Gestaltung des Anschlußelementes wird eine erhebliche Versteifung geschaffen.
  • 2. Die Kontaktstellen werden durch die Klemmstellen, die in die z-Form eingearbeitet sind, entlastet.
This solution has two main advantages:
  • 1. The z-shaped design of the connecting element creates a considerable stiffening.
  • 2. The contact points are relieved by the clamping points, which are incorporated in the z-shape.

Vorteilhafte weitere Ausgestaltungen der einzelnen Maßnahmen der Erfindung sind in den Unteransprüchen gekennzeichnet. So können an den Klemmteilen zusätzlich Verstärkungsflansche angebracht werden. Die Erfindung wird anhand der in der Zeichnung dargestellten Ausführungsbeispiele näher erläutert.Advantageous further developments of the individual measures of the invention are characterized in the subclaims. Reinforcement flanges can also be attached to the clamping parts. The invention is explained in more detail using the exemplary embodiments shown in the drawing.

Es zeigt :

  • Figur 1 das z-förmige Anschlußelement mit und ohne Verstärkungsflansche in der Draufsicht,
  • Figur 1a das Anschlußelement ohne Verstärkungsflansche nach Fig. 1 in der Vorderansicht,
  • Figur 2 das Anschlußelement als Doppelkontakt mit und ohne Verstärkungsflansche in der Draufsicht,
  • Figur 2a das Anschlußelement ohne Verstärkungsflansche nach Fig. 2 in der Vorderansicht,
  • Figur 3 das Anschlußelement mit eingelegter Kabelader in der Draufsicht,
  • Figur 3a die Vorderansicht nach Fig. 3 und
  • Figur 3b die Seitenansicht nach Fig. 3a.
It shows :
  • 1 shows the z-shaped connecting element with and without reinforcing flanges in a top view,
  • FIG. 1 a shows the connection element without reinforcing flanges according to FIG. 1 in a front view,
  • 2 shows the connection element as a double contact with and without reinforcing flanges in a top view,
  • 2a shows the connecting element without reinforcing flanges according to FIG. 2 in a front view,
  • 3 shows the connection element with inserted cable core in a top view,
  • Figure 3a shows the front view of Fig. 3 and
  • Figure 3b shows the side view of Fig. 3a.

Wie die Fig. 1 zeigt, ist das Anschlußelement 1 z-förmig ausgebildet. Das Anschlußelement 1 weist zwei Klemmteile 3 und einen die beiden Klemmteile 3 verbindenden Kontaktierungsteil 2 auf. Durch diese erfinderische Gestaltung des Anschlußelementes 1 erhält das Anschlußelement 1 eine erhebliche Versteifung und kann so als freistehendes Element - ohne zusätzliche Abstützung - verwendet werden.As shown in Fig. 1, the connection element 1 is Z-shaped. The connecting element 1 has two clamping parts 3 and a contacting part 2 connecting the two clamping parts 3. Through this inventive design of the connection element 1, the connection element 1 receives a considerable stiffening and can thus be used as a free-standing element - without additional support.

Wie die Fig. 1 weiterhin zeigt, können an den Klemmteilen 3 zusätzliche Verstärkungsflansche 5 angeordnet werden.As FIG. 1 also shows, 3 additional reinforcing flanges 5 can be arranged on the clamping parts.

Werden die Klemmteile 3, 3' zweier Anschlußelemente 1, 1' miteinander verbunden - wie die Fig. 2 zeigt - so entsteht ein Doppelkontakt.If the clamping parts 3, 3 'of two connection elements 1, 1' are connected to one another - as shown in FIG. 2 - a double contact is created.

Auf diese Weise können zwei nebeneinander angeordnete Adern angeschlossen werden.In this way, two cores arranged side by side can be connected.

Um die Anschlußelemente 1 auf z. B. einer Leiterplatte 6 zu befestigen, sind -wie die Fig. 1a a und 2a zeigen - Steckstifte 4 im unteren Bereich des Anschlußelementes 1 angeordnet.To the connection elements 1 on z. B. to attach a circuit board 6, - as shown in FIGS. 1a a and 2a - pins 4 are arranged in the lower region of the connecting element 1.

Insbesondere die Befestigung dieser Anschlußelemente 1 auf Leiterplatten 6 in der Elektronik läßt einen hohen Bedarf erwarten.In particular, the attachment of these connection elements 1 on printed circuit boards 6 in the electronics can expect a high demand.

Die Fig. 3, 3a und 3b zeigen den Anschluß einer Kabelader 7, wobei die Kontaktierung nach dem bekannten Prinzip durchgeführt wird.3, 3a and 3b show the connection of a cable wire 7, the contacting being carried out according to the known principle.

Ein dazu geeignetes Anlegewerkzeug weist in einem Griff ein sich axial in einer Hülse bewegendes, durch eine Feder gefedertes Druckstück auf, das die Kabelader in den Kontaktschlitz drückt, wobei die Hülse das Anschlußelement abstützt. An der Hülse ist außerdem ein Messer zum Abschneiden der Kabeladern nach der Kontaktierung angeformt.A suitable application tool has in a handle an axially moving in a sleeve, spring-loaded pressure piece that presses the cable core into the contact slot, the sleeve supporting the connecting element. A knife is also formed on the sleeve for cutting off the cable cores after contacting.
