Definitions

  • the present invention relates to a fuse switch with an insulating material housing, in which two live housing contacts are arranged in a stationary manner and with a slide switch, also made of insulating material, for accommodating a fuse cartridge, which is displaceable or pivotable between an ON position and a switch-off or exchange position in the insulating material housing End contact caps are in direct contact with the fixed housing contacts in the switched-on position and are spaced apart from the fixed housing contacts in the switched-off or replacement position.
  • Fuse switches are used to connect a fuse cartridge serially into a current-carrying conductor, so that the fuse can be used to monitor the current flow in said conductor and to be interrupted by melting the fuse wire in the cartridge when a predetermined maximum value is exceeded.
  • fuse switch In the designs of fuse switches known to date, the problem usually arises that the fuse cartridge is not easily accessible when the slide switch is in the switch-off or replacement position and the removal of a broken or inserting an intact fuse cartridge is difficult. It is an object of the present invention to provide a fuse switch of the type discussed at the outset in which this problem is avoided and the fuse cartridge is easily accessible in the off or replacement position of the slide switch in the sense of being easily removable by hand.
  • this is achieved by a slidably mounted slide in the slide, holding the fuse cartridge with a pin which engages in a slide arranged on the insulating housing, which slide is shaped so that the slide is displaced as far as the slide moves or swivels that the fuse cartridge protrudes in sections over the slide switch.
  • the section of the fuse cartridge projecting beyond the slide switch can be gripped by hand and a fuse cartridge can thus be removed from the slide valve or inserted into the slide valve without any problems. Due to the interaction of the pin and the setting, the safety cartridge is automatically brought into the easily accessible position during the displacement or pivoting of the slide switch; the system operator does not need to take any steps in this regard, but only carry out the unavoidable displacement or pivoting of the slide switch. In a further development of the invention it can be provided that at least a portion of the link deviates from the displacement or pivoting direction of the slide switch. The slide displacement according to the invention is thus achieved particularly reliably.
  • the link has two sections, the first section running in the direction of the displacement or pivoting direction of the slide switch and the second section deviating from the displacement or pivoting direction of the slide switch.
  • the housing contacts are preferably arranged with their longitudinal axis running in the direction of the displacement or pivoting direction.
  • both sections of the link extend in a straight line and that the second section encloses an angle in the range between 30 and 60 °, preferably 45 °, with the switching slide displacement direction.
  • the backdrop thus has a shape that is particularly easy to manufacture but nevertheless fulfills the purpose according to the invention.
  • a contact plate is attached to an end contact cap of the fuse cartridge and has a section which projects beyond the slide and comes into contact with a connection contact of the signal circuit when the slide switch is in the switched-on position.
  • Such a contact plate has the advantage over the likewise conceivable possibility of designing a connection contact of the signal circuit as a sliding contact that its section provided for establishing an electrical connection to the connection contact neither during the insertion or removal of the fuse cartridge nor during the displacement of the slide on other components of the fuse switch grinds.
  • the abrasion of the sliding contact as well as of the switch components along which the sliding contact rubs results from this grinding.
  • connection contact of the signal circuit coming into contact with the contact plate is formed by the connection wire of a component of the signal circuit.
  • the outlay on components of the signal circuit can thus be kept low by saving a separate component which forms the connection contact.
  • fuse switches of the type mentioned at the outset are continuous, i.e. can be moved or swiveled without any resistance between the switch-on and switch-off or switch-off positions.
  • This makes it possible to slowly remove or remove the end contact caps of the fuse cartridge from the housing contacts by slowly moving or pivoting the slide switch.
  • the circuit protected by the fuse cartridge can thus be opened slowly, during which slow opening causes large contact resistances between the housing contacts and the end contact caps or arcs can also occur between the said components. Both phenomena lead to strong local heating, which can lead to damage and / or destruction of the fuse switch.
  • this object is achieved by a latching connection which positively fixes the slide switch in its switched-on position in the housing.
  • this latching connection counteracts said displacement or pivoting movement with a holding force.
  • a relatively large force must therefore be exerted on the slide switch at the start of the movement. If the holding force of the latching connection is then exceeded, an average person cannot suddenly reduce the built-up force again; rather, the built-up force leads to an abrupt start of the pivoting or shifting movement and subsequently to an overall rapid displacement or pivoting of the Slide switch.
  • this also ensures that the end contact caps of the fuse cartridge are suddenly separated from the housing contacts, so that the problems occurring in the prior art are effectively avoided.
  • the latching connection fixes at least one on the slide switch or in the housing Latch and at least one indentation arranged in the housing or on the slide switch, into which indentation the snap lug engages in the switched-on position of the slide switch.
  • Such a snap connection can be made particularly easily and is also particularly reliable due to its simple structure.
  • the latching lug is arranged at the first free end of a leaf spring, which leaf spring is fixed with its other end to the slide switch or in the housing.

If such a shift is carried out, a relatively large force, namely a force that overcomes the holding force of the latching connection, must be exerted on the slide switch 22 already at the beginning of this shift.
  • the latching connection according to the invention can also be provided in the case of a fuse switch, the slide switch 22 of which has the shapes shown in FIGS. 10a, b and 11.12. In this case, as explicitly shown in Fig. 1.12, different from Fig. 2.3, it is provided to fix the leaf spring 52 with the latch 50 in the housing 1 and to form the indentation 51 on the slide switch 22.
  • latching connection according to the invention just discussed is completely independent of the presence of a sliding carriage 24. Said snap-in connection can therefore also be provided in those fuse switches which do not have a slide 24 and in which the fuse cartridge 20 is held directly on the slide switch 22.

Abstract

L'invention concerne un coupe-circuit à fusible comprenant un boîtier isolant (1) dans lequel deux contacts de boîtier (14), conducteurs de tension, sont placés de manière fixe. Ce coupe-circuit à fusible comprend en outre un curseur de commutation (22) constitué également d'un matériau isolant, guidé de manière à pouvoir coulisser ou pivoter dans le boîtier isolant entre une position de mise en circuit (fig. 3 et fig. 12) et une position de mise hors circuit ou de remplacement (fig. 2 et fig. 11), ledit curseur de commutation servant à recevoir une cartouche fusible (20) dont les caches de contacts terminaux (21), en position de mise en circuit (fig. 3 et fig. 12), viennent directement en contact avec les contacts de boîtier fixes (14), et, en position de mis hors circuit ou de remplacement (fig. 2 et fig. 11), se trouvent à distance de ces derniers (14). Ce coupe-circuit à fusible comprend également un chariot (14) maintenant la cartouche fusible (20) et monté de manière à pouvoir coulisser dans le curseur de commutation (22), ledit chariot comprenant un tenon (27) qui vient s'emboîter dans une coulisse (28) montée sur le boîtier isolant (1) et conçue de sorte que le chariot (24), lors du coulissement ou du pivotement du curseur de commutation (22), soit déplacé à une telle distance de ce dernier que la cartouche fusible (20) dépasse en partie le curseur de commutation (22).
