Description

Die Erfindung bezieht sich auf eine quergeteilte elektrische Einrichtung, wie Stecker oder Kupplung, mit einer mehrteiligen, schellenartig ausgebildeten, durch Schrauben (id. dgl. zusamnienfügbaren Zugentlastung für ein in das Isolierstoffgehäuse der Einrichtung einzuführendes Kabel und am Unterteil in Längsrichtung der Einrichtung zwischen den Anschlußelcmenlen angebrachten Trennwänden, wobei eine etwa in der Mitte des Unterteiles angeordnete Trennwand bis zur Kabeleinführung hochgezogen und an ihrem freien Ende als ortsfester Teil der Zugentlaslungsschclle ausgebildet ist, nach Patent 1218 034.The invention relates to a transversely divided electrical device, such as a plug or coupling, with a multi-part, clip-like strain relief that can be joined together by screws (id for a cable to be inserted into the insulating housing of the device and on the lower part in In the longitudinal direction of the device between the connection elements, partition walls, wherein a partition arranged approximately in the middle of the lower part is pulled up to the cable entry and is designed at its free end as a stationary part of the strain relief loop, according to the patent 1218 034.

An sich sind derartige quergeteilte elektrische Einrichtungen vorteilhaft, nicht zuletzt deshalb, weil die Zugentlastuugsschelle weitgehend von den elektrisch leitenden Teilen getrennt ist, so daß beim Lösen einer Ader aus der Anschlußstelle ein Kurzschluß ausgeschlossen wird. Andererseits hat man bisher den der Erdleitung zugeordneten Anschlußkontakt auf der dem Gehäuseinnern zugewandten Seite des Unterteiles des Gehäuses befestigt, und zwar so, daßer seitlich neben einem in das Gehäuse ragenden Bereich des Erdkontaktes liegt. Eine solche Anord-.nung gewährleistet nicht die für den Gebrauch zu fordernde gute Kontaktgabe zwischen Anschlußkontakt und Erdkontakt. Außerdem müssen· bisher Anschliißkontakt und Erdkontakt unabhängig voneinander am Unterteil befestigt werden.In itself, such transversely divided electrical devices are advantageous, not least because the Zugentlastuugsschelle is largely separated from the electrically conductive parts, so that when loosening a wire from the connection point is excluded. On the other hand, one has so far the connection contact assigned to the earth line on the side of the housing that faces the interior of the housing Lower part of the housing fastened in such a way that it laterally next to a protruding into the housing Area of earth contact. Such an arrangement does not guarantee the good contact between the connection contact which is required for use and earth contact. In addition, up to now the connection contact and earth contact have to be independent of one another attached to the lower part.

Der Erfindung liegt die Aufgabe zugrunde, elektrische Einrichtungen der eingangs näher gekennzeichneten Art so zu verbessern, daß bei" ihrem Gebrauch stets eine gute Kontaktgabe zwischen Erd- und Anschlußkoiitakt gewährleistet ist. Außerdem soll die Montage dieser Teife und ihre Benutzung vereinfacht werden. Dieses Ziel ist erfindungsgemäß erreicht durch eine seitlich am Mittel-(Erd-)Kontakt befestigte Anschlußbuchse. Durch die Befestigung der Anschlußbuchse seitlich am Erdkontakt bei der erfindungsgemäßen elektrischen Einrichtung erhält man eine direkte Verbindung zwischen diesen beiden '.!"eilen und damit eine gute Kontaktgabe. Durch die Anbringung der Anschlußbuchse am Erdkontakt entfallen getrennte Befestigungen für diese beiden Teile. Zugleich kann durch die Anschlußbuchse im Zusammenwirken mit anderen als Anschläge wirkenden Teilen der elektrischen. Einrichtung die Lage des Erdkontaktes im Gehäuse fixiert werden. Die Anschlußbuchse läßt sich dabei in Längsrichtung der elektrischen Einrichtung anordnen, was den Vorteil hat, daß die Anschlußleitung in Längsrichtung eingeführt und festgeklemmt werden kann.The invention is based on the object of providing electrical devices of the type specified in the introduction To improve the type so that when it is used, there is always good contact between earth and and connection coiitakt is guaranteed. Besides that the assembly of this Teife and its use should be simplified. This goal is according to the invention achieved by a connection socket attached to the side of the central (earth) contact. Through the attachment the connection socket on the side of the earth contact in the electrical device according to the invention you have a direct connection between these two '.! "and thus a good contact. Through the Attaching the connection socket to the earth contact eliminates the need for separate fastenings for these two parts. At the same time, through the connection socket in cooperation with other than stops acting parts of the electrical. Facility to fix the position of the earth contact in the housing. The connection socket can be arranged in the longitudinal direction of the electrical device, which has the advantage has that the connecting line can be inserted and clamped in the longitudinal direction.

Es ist bereits eine Zugentlastungsvorrichtung bekannt, die aus einem Steg und einer U-förmigen Schelle besteht, welche den Steg umfaßt und eine Spannschraube trägt. Mittels dieser Spannschraube kann das vom Steg und von tier Außenseite der Schelle gebildete Hinspannlager für das Kabel beliebig verengt werden. Seitlich an dem Steg ist dabei eine Anschlußstelle für eine Erdleitung vorgesehen (deutsches Gebrauchsmuster I 735 692).A strain relief device is already known, which consists of a web and a U-shaped There is a clamp, which includes the web and carries a tensioning screw. By means of this clamping screw can do that from the jetty and from the outside of the animal Clamp formed additional bearings for the cable as desired be narrowed. A connection point for a ground line is provided on the side of the web (German utility model I 735 692).

Es empfiehlt sich, die Anschlußbuchse quer zur Längsrichtung mit dem Mittel-(Erd-)Kontakt zu vernieten und mit einer Anschlußschraube zu versehen. Zur Erleichterung des Vemietens hat die Anschlußbuchse zweckmäßig einen seitlichen Fortsatz, der eine Bohrung des Erdkontaktes durchgreift und dann zu einem Nielkopf umgeformt wird. Dieser Fortsatz hat seinerseits .eine Bohrung zur Aufnahme der Anschlußschraube.It is advisable to rivet the connection socket transversely to the longitudinal direction with the central (earth) contact and to be provided with a connection screw. To make it easier to rent, the connection socket expediently a lateral extension that reaches through a hole in the earth contact and then is formed into a Nielkopf. This extension in turn has .eine hole to accommodate the Connection screw.

Es empfiehlt sich, die mittig angeordnete Trennwand mit einem Fuß durch den Mittel-(Erd-)Kontakt auf dem Unterteil zu befestigen. Dabei sitzt die Anschlußbuchse auf dem erwähnten Fuß auf. Bei dieser Ausführungsform ist die in der Mitte angeordnete Trennwand von dem Unterteil der elektrischen Einrichtung getrennt.It is advisable to put a foot through the central (earth) contact through the central partition to be attached to the lower part. The connection socket sits on the aforementioned foot. at In this embodiment, the dividing wall arranged in the middle is from the lower part of the electrical Separate facility.

ίο Der Mittelkontakt ist zweckmäßig in einem Durch-bruch der mittig angeordneten Trennwand gehaltert, wobei es sich empfiehlt, den Mittelkontakt in dem Durchbrach zu führen und die Trennwand eine Haltenase für den Mittelkontakt aufweifen zu lassen. Hierdurch wird ein Anschlag gebildet, der ein seitliches Bewegen des Mittelkontaktes in Richtung der Haltenase verhindert.ίο The center contact is useful in a breakthrough the centrally arranged partition, it is recommended that the center contact in the To lead breakthrough and to let the dividing wall widen a retaining lug for the central contact. This forms a stop that allows the center contact to move laterally in the direction of the Holding nose prevented.

Wenn auf eine zusätzliche Befestigung des Mittelkontaktes im Unterteil Wert gelegt wird, dann empfiehlt es sich, diesen Mittelkontakt durch Anschläge im Unterteil zu haltern.If you attach importance to an additional fastening of the center contact in the lower part, then we recommend it is enough to hold this central contact by means of stops in the lower part.

Die mittig angeordnete Trennwand ist auf dem Unterteil zweckmäßig in einer Aussparung angeord-' net.The centrally arranged partition is expediently arranged in a recess on the lower part. net.

Die mittig angeordnete Trennwand ist vorzugsweise mit mehreren längsgerichteten Durchbrüchen versehen. Dufeh-Ttiese Durchbrüche können die Adern des Kabels bequem zu den zugeordneten Anschlußkontakten geführt werden.The dividing wall arranged in the middle is preferably provided with several longitudinal openings Mistake. Dufeh-Ttiese breakthroughs can Cores of the cable are conveniently routed to the associated connection contacts.

Die Ober- und Unterteil der elektrischen Einrichtung verbindenden Schrauben sind zweckmäßig in im Oberteil vorgesehenen Längsrippen befestigt, die zwischen die Anschlußkontakte ragen. An sich ist es bekannt, bei elektrischen Einrichtungen Längsrippen zur Aufnahme von Verbindungsschrauben für Ober- und Unterteil des Gehäuses zu benutzen (deutsche Patentschrift 940 053).The screws connecting the upper and lower parts of the electrical device are useful in im Upper part provided longitudinal ribs attached, which protrude between the connection contacts. In itself it is known in the case of electrical equipment, longitudinal ribs to accommodate connecting screws for upper and to use the lower part of the housing (German patent specification 940 053).

Soweit es sich um ein aus gummielastischem Werkstoff und mit einem Schutzkragen versehenes Unterteil handelt, empfiehlt es sich, ein zwischen Einsätzen aus Isolierstoff angeordnetes Mittelstück zu benutzen. Diese Einsätze können aus Isolierpreßstoff gefertigt sein und dienen zur Verstärkung.As far as it is made of rubber-elastic material and provided with a protective collar If the lower part is concerned, it is advisable to have a middle piece arranged between inserts made of insulating material to use. These inserts can be made of molded insulating material and are used for reinforcement.

Ober- und Unterteil haben zweckmäßig doppelt abgesetzte Randkanten, durch die sie miteinander verbunden sind.The upper and lower parts have expediently double-stepped marginal edges through which they connect with one another are connected.

Die mittige Trennwand verjüngt sich zweckmäßig im Bereich der Zugentlastungsschelle nach dem Fuß hin.The central partition expediently tapers in the area of the strain relief clamp towards the foot there.

Und schließlich sind zweckmäßig dieser Trennwand zu beiden Seiten des Anschlußkontaktes liegende Stege angeformt. Grundsätzlich ist es bekannt, bei elektrischen Einrichtungen Stege zwischen den Anschlußkontakten vorzusehen (deutsche Auslege-5.5 schrift 1 045 506).And finally, this partition is expediently lying on both sides of the connection contact Molded on bars. In principle, it is known to have webs between the electrical devices Connection contacts to be provided (German Ausleger-5.5 script 1 045 506).
