Definitions

  • the invention relates to a transformer or autotransformer having a high-level electrical insulation, of comparatively simplified construction.
  • a transformer comprising a casing provided with apertured feet, in which said feet protrude from the bottom of said transformer, so as to define therewith a portal-like structure, at least one pair of said feet being provided on their inner sides with recesses, cooperating with one edge of a mounting channel-like structure having an "omega" or other profile, the bottom of the transformer being further provided at an intermediate position with transversal guide having mounted thereon a spring-operated latch co-operating with the opposite of said channel, so as to firmly lock the transformer, said guide having an inverted T profile and the latch which is slidably mounted on said guide has a corresponding C profile and is provided with an extension fitting in a longitudinal recess of said guide; a longitudinal slit for the introduction of a spring; and rear end-of-stroke stop.
  • a transformer is known of the type comprising an electrical insulating casing made of plastics material provided with slotted feet for securing the transformer in place.
  • a transformer is provided, of the type comprising an integral casing (5) of plastic material, the transformer being provided at its base, preferably at the corner regions of the core (4), with feet (6) protruding from the bottom of the casing, said feet having apertures for securing the transformer in place, at least one pair of said feet being provided co-planary with the bottom of the casing with recesses (8) cooperating with a first edge of a channel-like structure (9) having an "omega" or similar profile, a guide (10) being formed integrally at the bottom of the casing, the guide being transversally oriented with respect to the large surface of the transformer core and at an intermediate position with respect to the feet, said guide having in cross section a substantially inverted T-shaped profile and having a longitudinal recess (11), a spring operated latch (12) with a substantially C-shaped profile being slidably mounted on the guide and cooperating with the second edge of the channel-like structure for fixing the transformer on said channel-like structure, the latch being provided with
  • the transformer according to the invention comprises an insulating casing 5 made of plastics material having antifire characteristics, good electrical insulation features and good characteristics of resistance to chemical-physical stresses which encloses also the transformer bobin and which has the following functions:
  • the feet 6 protrude for an equal extent from the bottom of the transformer so as to define therewith a portal-like profile (Figure 4).
  • the feet which are located at one side of the transformer are provided - in the inner side thereof and co-planarly with the bottom of the casing 5 - with respective recesses 8 which permit the transformer to be overhangingly mounted on a DIN guide channel 9 having an "omega" profile ( Figure 3), of the type which is used commonly with electrical switchboards for supporting terminal blocks, remote-control switches and other components.
  • the recesses 8 co-operate with the upper edge of the channel 9, whereby the transformer is substantially suspended from said edge.
  • a latch device arranged intermediately of the bottom of the casing 5 and co-operating with the lower side of said channel.
  • a guide 10 with a substantially inverted "T"-shaped profile, having a longitudinal recess 11 is formed integrally at the bottom of the transformer at an intermediate position and with a transverse orientation.
  • Said guide mounts a latch device 12 of substantially C-shaped profile, provided with an extension 112 which fits into said recess 11 of said guide and which will be acted upon by an opposing spring 13 which may be introduced into said recess 11 through a window 14 provided longitudinally in said latch device, the latter being also provided with:
  • the guide 10 is tapered at the initial part thereof, as indicated at 16 in Figure 2, to permit the extension 112 of the latch to enter perpendicularly the recess 11 in said guide.
  • the housings 7-107 comprise small substantially parallelepipedal boxes B-B1, opened at one end whereinto a respective, preferably metallic slider 17 is inserted to embrace the tongue 3 or 103, said slider having in the top thereof a threaded hole co-operating with a screw 18 having a head 118 with a slot for a screwdriver, which rotatably engages, without protruding therefrom, a through-hole 19 in the top of each box B-B1, said head being provided with a collar 218 abutting against said top wall of the boxes.
  • the screw 18, moreover, is of such a length as to engage, at its lower end, the tongue 3 or 103.

  1. Transformator mit einem einstückigen Gehäuse (5) aus Kunststoffmaterial, wobei der Transformator an seiner Basis, vorzugsweise in den Gebieten der Ecken des Kerns (4) Füße (6) hat, die vom Boden des Gehäuses vorstehen, wobei die Füße Öffnungen haben, um den Transformator zu befestigen, wobei weiterhin wenigstens ein Paar der Füße coplanar mit dem Boden des Gehäuses ausgebildet ist, wobei Aufnahmen (8) mit einer ersten Kante einer kanalartigen Struktur (9) zusammenarbeiten, die ein Profil in Form eines Omega oder dergleichen hat, wobei weiterhin eine Führung (10) einstückig am Boden des Gehäuses ausgebildet ist, die in Bezug auf die breite Fläche des Transformatorkerns quer ausgerichtet ist, und zwar in Bezug auf die Füße in einer Zwischenlage, wobei die Führung im Querschnitt im wesentlichen ein Profil in Gestalt eines umgekehrten T hat und eine sich in Längsrichtung erstreckende Aufnahme (11), wobei eine federbetätigte Klinke (12) mit einem im wesentlichen C-förmigen Profil gleitend an der Führung befestigt ist und mit der zweiten Kante der kanalartigen Struktur zusammenarbeitet, um den Transformator an der kanalartigen Struktur zu befestigen, und wobei die Klinke mit einem Anschlag (212) versehen ist, der mit einer vorspringenden Kante der Führung zusammenarbeitet, die in Bezug auf die sich in Längsrichtung erstreckende Aufnahme quer ausgerichtet ist, mit einer Verlängerung (112), die in die längliche Aufnahme der Führung paßt und mit einem Längsschlitz (14) zum Einfügen einer Feder (13),
    dadurch gekennzeichnet,
    daß das Gehäuse akustisch isoliert ist und Kühlrippen (105) aufweist, und daß die Klinke an derjenigen Seite, die mit der kanalartigen Struktur zusammenarbeitet, einen oder mehrere Zähne (412) aufweist, die eine geneigte Seite haben, so daß sie sich an die Dicke der zweiten Ecke des der Befestigung dienenden Kanals selbsttätig anpassen.
