Description

Stromspule für Elektrizitätszähler od. dgl. Die Erfindung betrifft eine Stromspule für Zähler od. dgl., bei der zum Anschluß dienende Wicklungsleiter bis zur äußeren Gehäuseklemme geführt sind, wo sie gegebenenfalls gemeinsam mit den Außenanschlußleitern geklemmt werden. Meist besteht die Stromspule aus dickerem Rund- oder Profildraht.Current coil for electricity meters or the like. The invention relates a current coil for counters or the like, in which the winding conductor used for connection are led to the outer housing terminal, where they may be together with clamped to the external connection conductors. Usually the current coil consists of a thicker one Round or profile wire.

Im engeren Sinne bezieht sich die Erfindung auf eine Isolationsart solcher Spulen, bei denen diese zusammen mit den Anschlußleitern in Isoliermasse eingespritzt oder eingebettet sind. Bei bekannten Spulen dieser Art hat man die Bettungsmasse der Spule nicht am äußeren Spulenumfang aufhören lassen, sondern sie unter Bildung kurzer Rohrstutzen auch über die Anschlußleiter in unmittelbarer Nähe der Spule erstreckt, offenbar zu dem Zweck, die immer etwas stärker beanspruchte Stelle, an der der biegsame Leiter in den starren Wicklungskörper übergeht, besonders zu schützen. Im übrigen sind aber die Anschlußleiter in der üblichen Weise ausgeführt, d. h., die Anschlußleitungen werden an die aus den Rohrstutzen überstehenden Drahtenden angeklemmt oder angelötet, oder diese Drahtenden müssen bis zu den Apparateklemmen verlängert sein.In the narrower sense, the invention relates to a type of insulation such coils, in which these together with the connecting conductors in insulating material injected or embedded. In known coils of this type you have the Do not let the bedding material of the coil stop at the outer circumference of the coil, but rather it with the formation of short pipe sockets also over the connecting conductors in the immediate vicinity the coil extends, apparently for the purpose, which was always a little more stressed Particularly the point at which the flexible conductor merges into the rigid winding body to protect. Otherwise, however, the connecting conductors are designed in the usual way, d. That is, the connecting lines are attached to the wire ends protruding from the pipe socket clamped or soldered, or these wire ends must clamp up to the apparatus be extended.

Im Gegensatz dazu befinden sich erfindungsgemäß die Anschlußleiter in einem formfesten, bis zu den Anschlußklemmen reichenden gemeinsamen Fortsatz des die Spule umgebenden Isolierkörpers. Dieser Fortsatz kann unter Freilassung der Anschlußenden in Dichtungsteilen, beispielsweise von Kegelform oder umschließenden Ringen, Wülsten, endigen, um so die Anschlußenden mit dem Klemmenstück besser abdichten zu können und das Eindringen von Staub und Feuchtigkeit in das Gehäuseinnere zu verhüten.In contrast to this, according to the invention, the connecting conductors are located in a dimensionally stable joint extension reaching up to the terminals of the insulating body surrounding the coil. This appendix can be released the connection ends in sealing parts, for example conical or enclosing Rings, beads, ends in order to better seal the connection ends with the terminal piece and the ingress of dust and moisture into the interior of the housing prevent.

Die Erfindung bietet den Vorteil, daß z. B. die Stromspule eines Elektrizitätszähler mit ihren Anschlüssen wie ein starrer, wenn auch vielleicht etwas elastisch biegbarer Konstruktionsteil bei der Montage gehandhabt werden kann, bei dem die Gefahr einer bleibenden Deformation ausgeschlossen ist. Die Leiter haben dabei an dem Zählerklemmbrett ohne weiteres den richtigen Abstand, so daß also eine besondere Ausrichtung und Zurechtbiegung fortfällt. Außerdem ergeben sich eine hervorragende Isolation und mechanischer Schutz.The invention has the advantage that, for. B. the current coil of an electricity meter with its connections like a rigid one, even if it is perhaps a little elastically bendable Structural part can be handled during assembly, in which the risk of a permanent deformation is excluded. The conductors have to be attached to the meter terminal board without further ado the correct distance, so that a special alignment and No bending over. In addition, there is excellent insulation and mechanical protection.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung Fig. 1 und 2 in zwei verschiedenen Ansichten dargestellt.An embodiment of the subject matter of the invention is shown in the drawing Fig. 1 and 2 shown in two different views.

Die beiden Stromspulen 1 sind mit einem Isolierblock 2 umspritzt, unter Freilassung der inneren Spulenkanäle, durch die die Schenkel des Stromeisens 3 in bekannter Weise gesteckt werden. Der Isolierblock 2 hat einen flachen Fortsatz 4, der die zum Anschluß dienenden Enden 5 der Spulenwicklung umschließt. Er wird am besten zusammen mit dem Block 2 gespritzt. Die Drahtenden 6 sind frei gelassen. Der Fortsatz 4 endigt in konischen Dichtungsteilen 7, die in entsprechende hohlkegelige Höhlen des Klemmenstückes eingesteckt werden. Auf diese Weise sind die Stromspule und ihre Zuleitung hervorragend isoliert und gegen Kriechströme und überschlag geschützt. Auch ist diese Ausführungsform mechanisch widerstandsfähig und zweckmäßig und günstig bei der Herstellung des Zählers.The two current coils 1 are encapsulated with an insulating block 2, leaving the inner coil channels free, through which the legs of the current iron 3 can be plugged in in a known manner. The insulating block 2 has a flat extension 4, which encloses the ends 5 of the coil winding serving for connection. He will ideally injected together with block 2. The wire ends 6 are left free. The extension 4 ends in conical sealing parts 7, the corresponding hollow conical Holes of the terminal piece are inserted. This is how the current coil is and their supply line is excellently insulated and protected against leakage currents and flashovers. This embodiment is also mechanically resistant and expedient and inexpensive in the manufacture of the meter.
