Description

Isolierstoffgehause. für gekapselte elektrische Anlagen (FÜr-die Anmeldung wird die Priorität der Schaustellung auf der Technischen Messe Hannover vom 27. 4. 1958 in Anspruch genommen.) In gekapselten elektrischen Anlagen werden aus Gehäuseunterteil . und Deckel bestehende Gehäuse verwendet, die zur Aufnahme von elekt'rischen Geräten,.-insbesondere. Schal, tgeraten, dienen. Diese Gehäuse bestehen in der'Regel aus Guß oder Blech. Man.. ist auch schon dazu übergegangen, für den Gehäuseunterteil und Deckel als Baustoff Isolierstoff zu verwenden. Auch an den aus Isolierstoff bestehenden Gehäusen hat man bisher die Schrauben,-die den Deckel an dem Gehäuseuntertei'l befestigen, aus Metall'gefertigt. Insulated housing. for encapsulated electrical systems (for the Registration becomes the priority of the exhibition at the Technical Fair Hanover dated April 27, 1958.) In encapsulated electrical systems from the lower part of the housing. and cover existing housings used to accommodate of electrical devices, - in particular. Scarf, guilty, serve. This housing are usually made of cast iron or sheet metal. Man .. has already gone over to to be used as a building material insulating material for the housing base and cover. Even to those made of insulating material Housings have so far been the Screws that fasten the cover to the lower part of the housing, made of metal.

Die Neuerung betrifft ein'Isolierstoffgehäuse mit Gehäuseunterteil und Deckel für gekapselte elektrische Anlagen. Neuerungsgemäß wer-. den für Deckel und Gehäuse aus Isolierkunststoff bestehende Verbindungsschrauben verwendet,'die an ihrem im Querschnitt großen Schabt ein'Gewinde mit großer Flankenlange, insbesondere Sägezahn- gewi-hde, und an-ihrem Kopf einen Kreuzschlitz haben. Die Verbin- dungsschrauben gemäß der Neuerung besitzen große Betigkeit und lassen sich auch nach längerer Betriebszeit bequem an dem Isolier- stoffgehäuse aus-und einschrauben.The innovation relates to an insulating material housing with a housing base and cover for encapsulated electrical systems. According to the innovation. the existing connecting screws for cover and housing made of insulating plastic are used, 'the large in cross-section on their Scrapes a thread with a large flank length, especially sawtooth wi-hde, and have a Phillips-head on their head. The connection extension screws according to the innovation have great activity and can also be conveniently attached to the insulating Unscrew and screw in the fabric housing.

In der Zeichnung ist die, Neuerung dargestellt. Die Fig. 1 zeigt eine Aufsicht des neuerungsgemäßen Gehäuses,-die Fig. 2 einen Schnitt A-B. In den Fig. 3 bis 5 sind Einzelheiten für sich wieder- gegeben. Das Isolierstoffgehäuse'gemäß der Neuerung besteht aus dem Gehäuseunterteil 1 und dem Deckel 2. Zur Verbindung des Deckels 2 mit dem Gehäuseunterteil'1 dienen Schrauben 3, die vollständig aus Isolierkunststoff bestehen. Da die Festigkeit dieses Baustoffes kleiner ist als, die des Metalls, sind die Schrauben mit einem großen Querschnitt im Schaft versehen. Weil praktisch jeder Kunst-,, ^,, stoff zu einer Wässeraufnahme neigt, die. zu einer Quellung des Baustoffes führt-,'. ist für das Gewinde 4 ein solches mit großer Flankenlänge, insbesondere ein Sägezahngewinde, vorgesehen (Fig. 5).In the drawing, the innovation is shown. Fig. 1 shows a plan view of the housing according to the innovation, -the Fig. 2 shows a section AB. In Figs. 3 to 5 details are again for themselves given. The insulating housing 'according to the innovation consists of the Housing lower part 1 and the cover 2. To connect the cover 2 to the housing lower part 1, screws 3 are used, which consist entirely of insulating plastic. Since the strength of this building material is less than that of metal, the screws are provided with a large cross-section in the shaft. Because practically every plastic tends to absorb water. leads to swelling of the building material, '. For the thread 4, one with a large flank length, in particular a buttress thread, is provided (FIG. 5).

Ein derartiges Gewinde'kann dem möglichen Quellprozeß, der aus Isolierkunststoff bestehenden Teile insòfern/Rechnung tragen, als es ein vergrößertes Grundspiel zwischen dem Gewinde des Gehäuseunterteils und. dem der Schrauben zuläßt. Um an dem Schraubenkopf die Schlitzkante der Verbindungsschrauben weitgehend zu schonen, hat die Schraube einen Kreuzschlitz 5. Dieser kann erheblich tiefer als der Schlitz bei den üblichen Metallschrauben gehalten werden.' -Hierdurch kann das Eingreifen eines Schraubenziehers tiefer als üblich erfolgen. Da der Kreuzschlitz zwei'sich kreuzende Einzelschlitze darstellt, wird der Gebrauch eines Einzels. chlitzes erheblich herabgesetzt, und die Gefahr des vorzeitigen Ausbrechens der Schlitzkanten ist vermieden.' 1 Schutzanspruch- 5Figuren- Schutzanspruch: Isolierstoffgehäuse mit Gehäuseunterteil und Deckel für gekapselte elektrische Anlagen, das zur Aufnähme"von elektrischen Geräten, *.. ?.-'-'' insbesondere Schaltgeräten,'dient'gekennzeichnet durch aus Isolierkunststoff bestehende Verbindungsschrauben (3) für Deckel (2,) und Gehäuseunterteil. (1) edle an ihrem im Querschnitt großen Schaft CD Such a thread can take account of the possible swelling process of the parts made of insulating plastic, as there is an increased basic clearance between the thread of the lower housing part and. that allows the screws. In order to largely protect the slot edge of the connecting screws on the screw head, the screw has a cross recess 5. This can be held considerably deeper than the slot in conventional metal screws. ' -This allows a screwdriver to reach deeper than usual. Since the cross slot represents two intersecting single slots, the use of a single one is possible. slits are considerably reduced and the risk of the slit edges breaking out prematurely is avoided.
