Definitions

  • the present invention relates to a protective device for a contact Fuse insert with a main cap designed as a sand filling hole Contact and with a closure cap designed as the sand filling hole Contact, the protection device comprising a contact protection element made of conductive material, that completely completes the contact, at least in the effective range of a mating contact covers.
  • EP 0 017 815 A1 discloses a low-voltage circuit breaker with a fuse, which includes a fuse link with a receiving space.
  • the recording room points a foot contact that contacts the underside of a fuse link and that over Contact pieces can be connected to a connecting terminal.
  • a fuse switch which is a shift lever Includes foot contact for a fuse link.
  • the shift lever contacts the bottom a fuse link and can be connected to a switch terminal via contact pieces become.
  • a switchable, multi-pole fuse base is known, the one Receiving sleeve for the use of a fuse includes.
  • the receptacle serves as Foot contact for the fuse and is connected to a conductor rail via a rounded contact part connected.
  • the protective device comprises a contact protection element made of conductive Material that completes the contact at least in the effective range of a counter contact covers, wherein the protective device is designed so that it makes contact with the Contacted sand fill hole and at a distance from the contact closing the sand fill hole is arranged.
  • the area of action of a counter contact is to be understood as the area in the immediate vicinity Is close to the mating contact and, when used as intended, with the Mating contact comes into contact or at which the distance from the contact to the mating contact becomes so small that a sparkover occurs due to different potentials a switching arc can occur.
  • the contact protection element according to the invention makes the sensitive contact of the fuse link reliable against switching arcs, radio flashovers and also against one mechanical wear, caused by a sliding contact on the counter contact, protected during a switching operation. At the same time it is achieved that the Sand filling hole closing cap of the fuse link for closing the Circuit is no longer required. The circuit is directly over the main cap of the Fuse insert closed, causing high contact resistance between the main cap and sealing cap and associated line losses can be avoided. In this Connection is also made to the parallel registration (official file number of the German Patent and Trademark Office: 199 34 538.4) of the applicant.
  • the contact protection element is preferably a contact protection pan formed into which a contact area, in particular one Fuse link, essentially fully usable is. This ensures that when handling the System of contact automatically through the protection device is shielded without additional operating steps for are necessary for the operator. Through that as a contact protection pan trained contact protection element, the contact area is after shielded and protected in all directions. It is also possible to dimension the contact protection pan larger than the contact to be protected, so that the contact protection pan e.g. also at least over insulation areas adjacent to the contact extends. This ensures an optimal protective function of contact.
  • the contact protection element is preferably made of copper, silver or gold and has a thickness of at least 0.5 mm, preferred a thickness of 1 mm to 2 mm. For one thing good conductivity of the protective device and low Transition resistance ensured, on the other hand, that shows Material has a sufficient thickness so that it may still wear and tear of this protective device the lifespan at least not below the median lifespan of the other components of the system.
  • the contact protection element has two Contact points on a shielding level of the contact protection element protrude. This geometry is particularly suitable for the exact positioning of an essentially spherical segment-shaped counter-contact between the two Position contact points.
  • the contact points are preferably welded on and exist preferably made of a tin-silver compound.
  • the invention further relates to a safety plug for a switch fuse unit with a receiving area for a fuse link, according to the invention the fuse plug a protective device and a contact protection element as described above.
  • the invention also relates to a rocker switch for a Switch fuse unit in which a fuse link or a safety plug with a receiving area for one Fuse insert can be used, the rocker switch a Protection device and a contact protection element, such as they have been described above.
  • FIG. 1 shows a protective device 10 for a contact with a contact protection element 11, which as Contact protection pan is formed.
  • a contact protection pan trained contact protection element 11 is in the Fig. 1 from above, a contact of a fuse link in the essentially fully usable. The contact is then from Side walls 15 of the contact protection element 11 after almost all Shielded sides. The shield in the interrupted Area of the side walls 15 is by a step 16 of Contact protection element 11 ensured.
  • the protection device 10 also has one with the contact protection element 11 connected fastening device 13, which are parallel to the side walls 15 of the contact protection element 11 extends.
  • This fastening device 13 can e.g. on a rocker switch or a safety plug in a switch fuse unit can be securely attached.
  • the protective device 10 further comprises two contact points 12 on the underside of the contact protection element. In the in Fig. 1 is only one of the contact points 12 visible.
  • Fig. 2 shows the embodiment shown in Fig. 1 in a bottom view. 2 are the two contact points 12 clearly visible, between which and in contact with where a counter contact is safely positioned.
  • Fig. 2 are also the side walls 15 of the contact protection pan indicated.
  • the protective device shown in FIGS. 1 and 2 consists of Copper, the individual elements having a thickness of approximately 1.5 mm.
  • the contact points 12 consist of a Tin-silver alloy and are on the contact protection pan 11th welded.
  • Fig. 3 is a switch fuse unit 20 with a Switch rocker 30 according to the invention shown, which the in Fig. 1 and 2 includes protective device 10.
  • the protective device 10 is firmly connected to the rocker switch 30, so that it is with the rocker switch between an on position and a switch-off position can be moved back and forth is stored.
  • Fig. 3 there is the rocker switch in their on position.
  • a safety plug 40 with a Fuse insert 50 used in the rocker switch 30.
  • the fuse link 50 has as a contact a main cap 51 with a sand fill hole that with a cap 52 is closed. How well from the Fig. 3 can be seen, the rocker switch 30 and the protective device 10 designed so that by inserting the fuse plug 40 and the fuse link 50 the cap 52 of the fuse link 50 automatically into the as Contact protection pan trained protective device 10 out is, but not contacted.
  • the cap 52 of the Fuse insert 50 is completely through the contact protection element 11 shielded.
  • the contact is made between a bottom portion of the main cap 51 the fuse link 50 and the protective device 10.
  • the cap 52 is in the circuit bypassed so that the high contact resistance between Main cap 51 and cap 52 and thereby caused Line losses can be avoided.
  • the distance between the cap 52 and the underlying area of the protective device 10 less than a height of the cap 52 so that the Cap 52 not e.g. by blowing the Fuse higher pressure inside the fuse link 50 can be blown off.
  • Such one Blowing off and loosening the closure cap 52 would lead to that sand or similar material from inside the fuse link 50 can emerge and the switch fuse unit 20 could damage.
  • a spring 53 is arranged so that it is the protective device 10 preloaded and the protective device 10 against the fuse link 50 presses to make reliable contact between the contact protection element 11 and the main cap 51 of the Ensure fuse link 50.
  • a spring-loaded counter contact 60 only counteracts the contact element 11, i.e. there is no touch contact between the main cap 51 or the cap 52 of the Fuse link 50 and the counter contact 60 instead.
  • the main cap 51 and the cap 52 are through the contact protection element 11 shielded to the extent that the mating contact 60 also in such a close distance range this can lead to a sparkover due to different Potentials or a switching arc occur can.
  • a protective device 10 in the switch fuse unit 20 is only one application example represents.
  • the protective device according to the invention can also be used in other security systems, in particular Anti-rotation and plug-in systems, but also for Protection of any contacts are used, the loads, e.g. through switching processes or possible switching arcs, may be exposed.
