Abstract

Such a connection provides a receptacle (2) seated on the connection blade (1) with inclined support faces (26, 27) into which the solid end (24), which is constructed to be wedge-shaped in corresponding manner, of the heavy current cable can be hooked with area contact with the support faces of the receptacle (2). In order to produce good area contact between the receptacle (2) and the solid end (4) of the heavy current cable, the wedge faces of the solid cable end (4) are subdivided by recesses (41, 41') and (42, 42') and/or (41, 41") and 42, 42") extending over its length and/or width. <IMAGE>

Description

Die Erfindung betrifft eine lösbare Verbindung eines Hochstromkabels mit einem sammelschienenartigen Anschlußschwert, der im Oberbegriff des Anspruchs 1 umrissenen Gattung. Eine solche Verbindung ist beschrieben in der DE-PS 34 23 175.The invention relates to a releasable connection of a high-current cable with a busbar-like connecting sword, the type outlined in the preamble of claim 1. Such a connection is described in DE-PS 34 23 175.

Die vorbekannte Lösung setzt für den geforderten, Voraussetzung für einen guten Stromfluß bildenden Flächenkontakt zwischen dem kabelseitigen Anschlußstück und der dem Anschlußschwert zugeordneten, das Anschlußstück aufnehmenden Kontakttasche eine uneingeschränkt plane Ausbildung der in Wechselwirkung tretenden Flächen der Kontakttasche und des Anschlußstücks voraus, eine Vorgabe, deren Erfüllung eine aufwendige Bearbeitung dieser Flächen erfordert.The previously known solution requires, for the required, prerequisite for a good current flow, area contact between the cable-side connector and the contact sword assigned to the connecting piece receiving the connector, an absolutely flat design of the interacting surfaces of the contact pocket and the connector, a requirement, their fulfillment requires complex processing of these surfaces.

Ausgehend vom im vorausgehenden umrissenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die bekannte Verbindung so auszugestalten, daß der erforderliche Flächenkontakt zwischen der Kontakttasche und dem Anschlußstück des Kabelkopfes bei vergleichsweise geringem Aufwand an Fertigungskosten erzielt wird.Starting from the previously outlined prior art, the invention has for its object to design the known connection so that the required surface contact between the contact pocket and the connector of the cable head is achieved with comparatively little effort in manufacturing costs.

Die Aufgabe wird erfindungsgemäß bei einer gattungsgemäßen lösbaren Verbindung eines Hochstromkabels mit einem sammelschienenartigen Anschlußschwert durch eine Ausgestaltung insbesondere des Bestandteil des Kabelkopfes bildenden Anschlußstücks entsprechend dem kennzeichnenden Teil des Anspruchs 1 oder/und des Anspruchs 2 gelöst.The object is achieved according to the invention in a releasable connection of a high-current cable with a busbar-like connecting sword by an embodiment, in particular of the connector forming part of the cable head, in accordance with the characterizing part of claim 1 and / or claim 2.

Die Aufteilung der Anlageflächen des in die Kontakttasche einhängbaren Anschlußstücks in Teilbereiche stellt einen hinreichenden und dann auch einwandfreien Flächenkontakt zwischen dem Anschlußstück und der Kontakttasche bei vergleichsweise geringen Anforderungen an die Bearbeitung der Anlageflächen sicher.The division of the contact surfaces of the connector that can be hooked into the contact pocket into partial areas ensures adequate and then also flawless surface contact between the connector and the contact pocket with comparatively low demands on the machining of the contact surfaces.

Eine spezielle Ausgestaltung der Erfindung ergibt sich aus Anspruch 4. Diese Ausgestaltung stellt sicher, daß dem Anschlußstück ein hinreichender tragender Querschnitt verbleibt.A special embodiment of the invention results from claim 4. This embodiment ensures that the connector has a sufficient load-bearing cross section.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispieles weitergehend erläutert. Es zeigen:

Das abgebrochen dargestellte Anschlußschwert ist mit 1 bezeichnet. An dem Anschlußschwert 1 ist die sogenannte Kontakttasche 2 in Flächenkontakt (11/22) mit dem Anschlußschwert 1 angeschraubt (3). Die U-profilförmige, mit ihrem Steg 21 gegen das Anschlußschwert 1 anliegende Kontakttasche 2 ist von oben (Pfeil A in Fig. 2) und von vorn (Pfeil B in Fig. 1) zum Einhängen des Bestandteil des Kabelkopfes 4′ bildenden massiven Anschlußstücks 4 zugänglich, das über seine Breitseiten (41) und (42) Flächenkontakt mit den Schenkeln 23, 24 der Kontakttasche 2 eingeht, wobei aus den nach unten einfallenden AnlageFlächen 26, 27 der Kontakttasche 2 einerseits und den korrespondierenden keilförmig verlaufenden Flächen (41, 42) des Anschlußstückes 4 andererseits ein Klemmsitz des Anschlußstückes 4 in der Kontakttasche 2 resultiert. Eine zusätzliche Sicherung bilden in die Überstände der Kontakttaschenschenkel 23, 24 über das Anschlußstück 4 eingezogene Schrauben 6.The connection sword shown broken off is designated 1. The so-called contact pocket 2 in surface contact (11/22) with the connection sword 1 is screwed onto the connection sword 1 (3). The U-profile-shaped, with its web 21 against the connecting sword 1 contact pocket 2 is from above (arrow A in Fig. 2) and from the front (arrow B in Fig. 1) for hanging the part of the cable head 4 'forming solid connector 4 accessible, which makes surface contact with the legs 23, 24 of the contact pocket 2 via its broad sides (41) and (42), the contact surfaces 2, 26, 27 of the contact pocket 2 falling downwards falling on the one hand and the corresponding wedge-shaped surfaces (41, 42) the connector 4 on the other hand, a clamp fit of the connector 4 in the contact pocket 2 results. An additional safeguard is formed by the screws 6 inserted into the protrusions of the contact pocket legs 23, 24 via the connecting piece 4.

Die mit den Anlageflächen 26, 27 der Kontakttasche 2 korrespondierenden Keilflächen des Anschlußstücks 4 sind zum einen durch einen sich in Längsrichtung des Anschlußstücks 4 erstreckenden Rücksprung 43 bzw. 44 in dessen Breitseiten in im Abstand voneinander nebeneinander verlaufende Teilflächen 41 und 41′ bzw. 42 und 42′ und zum anderen durch einen eine Stufe bildende, sich über die Breite des Anschlußstückes 4 erstreckenden Rücksprung 46 bzw. 47 in seinen Breitseiten in Verbindung mit entsprechenden Rücksprüngen 28, 29 in den Schenkeln 23, 24 der Kontakttasche 2 dann auch noch weitergehend unter Bildung von insgesamt vier Kontaktbereichen aufgeteilt, von denen in der Zeichnung nur die Kontaktbereiche 41, 41′ und 41˝ bzw. 42, 42′ und 42˝ erscheinen.The wedge surfaces of the connecting piece 4 corresponding to the contact surfaces 26, 27 of the contact pocket 2 are, on the one hand, by a recess 43 or 44 extending in the longitudinal direction of the connecting piece 4 in the broad sides thereof in sub-areas 41 and 41 'or 42 and which are spaced from one another 42 'and on the other by a step forming, extending across the width of the connector 4 recess 46 and 47 in its broad sides in conjunction with corresponding recesses 28, 29 in the legs 23, 24 of the contact pocket 2 then also further with formation divided by a total of four contact areas, of which only the contact areas 41, 41 'and 41˝ or 42, 42' and 42˝ appear in the drawing.

Anstelle der beim dargestellten Ausführungsbeispiel gewählten Zuordnung der Kontakttasche 2 zum Anschlußschwert 1 kann die Kontakttasche naturlich auch mit einem ihrer Schenkel gegen das Anschlußschwert zur Anlage kommend dem Anschlußschwert zugeordnet werden.Instead of the assignment of the contact pocket 2 to the connection sword 1 selected in the illustrated embodiment, the contact pocket can of course also be assigned to the connection sword with one of its legs against the connection sword.
