Definitions
- the invention relates to an arrangement for attaching a test line to touch-proof covered, accessible via a cylindrical opening terminals of electrical devices.
- the invention is intended to improve an arrangement of the type mentioned above such that a versatile test is also possible on any devices with little effort. This is achieved in a simple manner in that a permanent-magnetic, cylindrical intermediate part is inserted between the test line or test plug and the connection.
- the intermediate part can be designed here as a bushing, but this is relatively difficult to manufacture as a permanent magnet. It is therefore more advantageous if a plug socket is connected to the permanent magnet on the outside of the base. In order to avoid spreading voltage outside the cover, it is advantageous if the permanent magnet and the plug socket are connected to one another via an insulating sheath. To ensure a safe transition, i. H. To ensure without large contact resistances between the permanent magnet and the socket, it is advantageous if a solderable layer is introduced between the permanent magnet and the socket.
- a simple connection between the permanent magnet and the socket can be achieved if there is an opening on the outside of the bottom of the plug socket which is adapted to the outer contour of the permanent magnet and into which the permanent magnet is pressed with the interposition of a thin, conductive film.
- the permanent magnet is designed as a screwdriver blade on the bottom side.
- the intermediate part consists of cobalt and rare earths, preferably samarium.
- the clamping screw 3 is screwed into the box terminal 4 indicated by dashed lines, which is connected to the actual connection 5.
- An insertion funnel 6 is used to insert the connecting conductor into the box terminal 4.
- the clamping screw 3 is not readily accessible from the cover side, so that it is not readily possible to check the connection to the test line 7 to which a test plug 8 is attached.
- the arrangement 9 according to the invention for attaching a test line is connected to the test plug 8.
- the arrangement 9 can be seen from FIG. 2. It consists of the permanent magnet 10 and the socket 11 for the test plug 8, which are connected to one another via a solderable layer 12.
- An insulating sheath 13 serves as protection against contact and for additional mechanical holding. To carry out the test, only the magnet 10 needs to be passed through the opening 14 in the cover 2 in order to come into an electrically conductive connection with the head of the clamping screw 3. It can be seen that there is only one arrangement per end of the test line, whereas in the prior art there is a separate socket for each individual terminal. It is also easily possible to adapt the plug hole 15 of the socket 11 to the test line 7 or the test plug 8 to be used. Fig.
- FIG. 3 shows a further embodiment of the arrangement according to the invention, according to which on the outside 16 of the bottom 17 of the socket 11 there is an opening 18 adapted to the outer contour of the permanent magnet 10, into which the permanent magnet 10 is pressed with the interposition of a thin, conductive foil 19 is.
- the permanent magnet 10 according to FIG. 3 runs out in the form of a screwdriver blade 20 on the bottom side.

Abstract
Description
Die Erfindung bezieht sich auf eine Anordnung zum Ansetzen einer Prüfleitung an berührungssicher abgedeckte, über eine zylinderförmige Öffnung zugängige Anschlußklemmen von elektrischen Geräten.The invention relates to an arrangement for attaching a test line to touch-proof covered, accessible via a cylindrical opening terminals of electrical devices.
Bei Anlagen mit Niederspannungs-Schaltgeräten, insbesondere in Steuerverteilungen, müssen Potentiale zwischen den Klemmen eines Gerätes bzw. zwischen verschiedenen Geräten gemessen werden können. Dies kann erforderlich sein zur Kontrolle beim Aufbau der Anlage oder aber zur Fehlersuche bei vorhandenen Störungen. Da die Anschlüsse der Geräte aus sicherheitstechnischen Gründen abgedeckt werden,, besteht kaum Möglichkeit, mit handelsüblichen Klemmen Potentiale abzugreifen, ohne hierzu Hilfspersonen zur Verfügung zu haben, die die Prüfspitzen auf die Anschlußschrauben oder auf eine andere, offene, abgreifbare, spannungsführende Stelle drücken. Dies führt zu einem relativ hohen Personal- und Zeitaufwand. Bei einer bekannten Anordnung (Druckschrift AR 8691 D 5 N. Industrie-Relais CA 2-F der Firma Telemecanique) der obengenannten Art ist daher auf der Kontaktzuleitung zusätzlich zu der Anschlußklemme eine Prüfbuchse befestigt, die durch eine gesonderte Gehäuseöffnung zugänglich ist. Abgesehen von den zusätzlichen Arbeitsgängen und dem Materialaufwand beim Anbringen einer derartigen Kontaktbuchse, die an jeder einzelnen Klemme vorhanden sein muß, sind diese Buchsen lediglich für den Durchmesser eines Steckers geeignet, so daß spezielle Prüfleitungen mit Stecker erforderlich sind.In systems with low-voltage switchgear, particularly in control distributions, it must be possible to measure potential between the terminals of a device or between different devices. This may be necessary to check when setting up the system or to troubleshoot existing faults. Since the connections of the devices are covered for safety reasons, there is hardly any possibility of tapping potentials with commercially available terminals without having auxiliary persons available who press the test probes onto the connection screws or onto another, open, tapped, live point. This leads to a relatively high expenditure of personnel and time. In a known arrangement (document AR 8691 D 5 N. Industrial relay CA 2-F from Telemecanique) of the type mentioned above, a test socket is therefore attached to the contact lead in addition to the connection terminal, which is accessible through a separate housing opening. Apart from the additional work steps and the cost of materials when attaching such a contact socket, which must be present on each individual terminal, these sockets are only suitable for the diameter of a plug, so that special test leads with plugs are required.
Durch die Erfindung soll eine Anordnung der obengenannten Art dahingehend verbessert werden, daß bei geringem Aufwand eine vielseitige Prüfung auch an beliebigen Geräten möglich ist. Dies wird auf einfache Weise dadurch erreicht, daß zwischen Prüfleitung bzw. Prüfstecker und Anschluß ein permanentmagnetisches, zylinderförmiges Zwischenteil eingefügt ist.The invention is intended to improve an arrangement of the type mentioned above such that a versatile test is also possible on any devices with little effort. This is achieved in a simple manner in that a permanent-magnetic, cylindrical intermediate part is inserted between the test line or test plug and the connection.
Es ist an sich bekannt, über Magnete Leitungen für Schweißgeräte (CA-A-907717) für Kopfhörer (CH-A-489121) oder für Sonden am Körper (US-A-4 067 342) zu kontaktieren. Hier handelt es sich jedoch generell um kleine, bei Berühung ungefährliche Spannungen (DE-A-1 805 539).It is known per se to contact lines for welding devices (CA-A-907717) for headphones (CH-A-489121) or for probes on the body (US-A-4 067 342) via magnets. However, these are generally small voltages that are harmless when touched (DE-A-1 805 539).
Bei der erfindungsgemäßen Anordnung ist keine Anpassung der Gehäusegeometrie an den Anschluß bzw. die Klemme notwendig und Abdeckungen im Gehäuse, an denen sich Prüfkrallen abstützen könnten, werden nicht benötigt. Das Zwischenteil kann hier als Buchse ausgebildet werden, was jedoch als Permanentmagnet relativ schwer herzustellen ist. Es is daher vorteilhafter, wenn eine Steckerbuchse an der Außenseite des Bodens mit dem Permanentmagneten verbunden ist. Um Spannungsverschleppungen außerhalb der Abdeckung zu vermeiden, ist es vorteilhaft, wenn Permanentmagnet und Steckerbuchse über eine Isolierumhüllung miteinander verbunden sind. Um einen sicheren Übergang, d. h. ohne große Übergangswiderstände zwischen dem Permanentmagnet und der Steckerbuchse, zu gewährleisten, ist es vorteilhaft, wenn zwischen Permanentmagnet und Steckerbuchse eine lotfähige Schicht eingebracht ist. Eine einfache Verbindung zwischen Permanentmagnet und Buchse läßt sich erreichen, wenn an der Außenseite des Bodens der Steckerbuchse einer der Außenkontur der Permanentmagneten angepaßte Öffnung vorhanden ist, in die unter Zwischenschaltung einer dünnen, leitfähigen Folie der Permanentmagnet eingepreßt ist. Um sicherzustellen, daß bei der Prüfung der Permanentmagnet auch auf der Anschlußschraube aufliegt, kann es vorteilhaft sein, wenn der Permanentmagnet an der Bodenseite als Schraubendreherklinge ausgebildet ist. Um auch bei Erschütterungen eine sichere Kontaktgabe zwischen Magnet und Anschluß zu gewährleisten, hat es sich als vorteilhaft erwiesen, wenn das Zwischenteil aus Kobalt und seltenen Erden vorzugsweise Samarium besteht.In the arrangement according to the invention, no adaptation of the housing geometry to the connection or the terminal is necessary, and covers in the housing on which test claws could be supported are not required. The intermediate part can be designed here as a bushing, but this is relatively difficult to manufacture as a permanent magnet. It is therefore more advantageous if a plug socket is connected to the permanent magnet on the outside of the base. In order to avoid spreading voltage outside the cover, it is advantageous if the permanent magnet and the plug socket are connected to one another via an insulating sheath. To ensure a safe transition, i. H. To ensure without large contact resistances between the permanent magnet and the socket, it is advantageous if a solderable layer is introduced between the permanent magnet and the socket. A simple connection between the permanent magnet and the socket can be achieved if there is an opening on the outside of the bottom of the plug socket which is adapted to the outer contour of the permanent magnet and into which the permanent magnet is pressed with the interposition of a thin, conductive film. To ensure that the permanent magnet also rests on the connecting screw during the test, it can be advantageous if the permanent magnet is designed as a screwdriver blade on the bottom side. In order to ensure reliable contact between the magnet and the connection even when shaken, it has proven to be advantageous if the intermediate part consists of cobalt and rare earths, preferably samarium.
Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben und die Wirkungsweise näher erläutert. Es zeigt
- Figur 1 ein elektrisches Gerät, beispielsweise ein Schütz, in perspektivischer Darstellung mit entsprechenden Anschlußklemmen,
Figur 2 eine Teilansicht der Abdeckung und der Anschlußschraube des Schützes mit dar- überliegender Anordnung zum Ansetzen der Prüfleitung, zum Teil im Schnitt, und- Figur3 einen Seitenschnitt durch eine weitere Ausführung der Anordnung zum Ansetzen einer Prüfleitung.
- 1 shows an electrical device, for example a contactor, in perspective with corresponding connection terminals,
- FIG. 2 shows a partial view of the cover and the connecting screw of the contactor with an overlying arrangement for attaching the test line, partly in section, and
- Figure 3 shows a side section through a further embodiment of the arrangement for attaching a test line.
Das Schaltgerät nach Fig. 1 besteht aus dem Sockel 1, der Abdeckung 2, durch die die Klemmschrauben 3 gegen Berührung abgedeckt sind. Die Klemmschraube 3 ist in die gestrichelt angedeutete Rahmenklemme 4 eingedreht, die mit dem eigentlichen Anschluß 5 in Verbindung steht. Zum Einführen des Anschlußleiters in die Rahmenklemme 4 dient ein Einführtrichter6. Wie die Fig. 1 zeigt, ist die Klemmschraube 3 von der Abdeckseite her nicht ohne weiteres zugänglich, so daß eine Überprüfung des Anschlusses mit der Prüfleitung7, an der ein Prüfstecker8 befestigt ist, nicht ohne weiteres möglich ist. Hierzu ist mit dem Prüfstecker8 die erfindungsgemäße Anordung 9 zum Ansetzen einer Prüfleitung verbunden. Die Anordnung 9 ist aus Fig. 2 zu ersehen. Sie besteht aus dem Permanentmagneten 10 und der Steckerbuchse 11 für den Prüfstecker8, die über eine lötfähige Schicht 12 miteinander verbunden sind. Zum Berührungsschutz und zum zusätzlichen mechanischen Halten dient eine lsolierumhüllung 13. Zum Durchführen der Prüfung braucht lediglich der Magnet 10 durch die Öffnung 14 der Abdeckung 2 hindurchgeführt zu werden, um mit dem Kopf der Klemmschraube 3 elektrisch leitend in Verbindung zu kommen. Es ist ersichtlich, daß hier lediglich eine Anordnung pro Ende der Prüfleitung vorhanden sein muß, wohingegen beim Stand der Technik für jede einzelne Klemme eine gesonderte Buchse vorhanden ist. Es ist auch ohne weiteres möglich, die Steckerbohrung 15 der Steckerbuchse 11 der zu verwendenden Prüfleitung 7 bzw. dem Prüfstecker 8 anzupassen. Die Fig. 3 zeigt eine weitere Ausbildungsmöglichkeit der erfindungsgemäßen Anordnung, nach der an der Außenseite 16 des Bodens 17 der Steckerbuchse 11 eine der Außenkontur des Permanentmagneten 10 angepaßte Öffnung 18 vorhanden ist, in die unter Zwischenschaltung einer dünnen, leitfähigen Folie 19 der Permanentmagnet 10 eingepreßt ist. Der Permanentmagnet 10 nach Fig. 3 läuft an der Bodenseite in die Form einer Schraubendreherklinge 20 aus. Die dünne, leitfähige Folie 19 besteht beispielsweise aus Kupfer GAL SN.1 consists of the base 1, the
