Description

Pronalazak se odnosi na napravu za zaštitu od iskrenja za vodič obložen izolacijskim slojem, sa dvije stezaljke, koje se mogu međusobno stegnuti jednim elementom za pritezanje, i koje između sebe formiraju najmanje jedan kanal za prihvaćanje jednog vodiča, pri čemu bar jedna od stezaljki ima zupce dužine koja odgovara debljini izolacijskog sloja, i sa rogom za odvod iskri. The invention relates to a spark protection device for a conductor coated with an insulating layer, with two clamps, which can be clamped together by a single tightening element, and which between them form at least one channel for receiving one conductor, wherein at least one of the clamps has teeth length that corresponds to the thickness of the insulating layer, and with a spark discharge horn.

Takva jedna naprava je poznata, na primjer, iz EP 0 387 865, i kod nje su između stezaljki predviđena dva kanala, od kojih jedan sa zupcima služi za prihvaćanje vodiča, dok drugi služi za prihvaćanje roga za odvod iskri. Ova naprava za zaštitu od iskrenja ima taj nedostatak što se kod njenog postavljanja moraju i vodič i rog za odvod iskri istovremeno postaviti između stezaljki, prije nego što se element za stezanje može pritegnuti, zbog čega je ugradnja komplicirana i najčešće zahtijeva dva radnika. Pored toga je mogućnost usmjeravanja roga za odvod iskri ograničena. One such device is known, for example, from EP 0 387 865, and in it two channels are provided between the clamps, one of which with teeth serves to accept the conductor, while the other serves to accept the spark discharge horn. This spark protection device has the disadvantage that when installing it, both the conductor and the spark arrester horn must be placed between the clamps at the same time, before the clamping element can be tightened, which is why the installation is complicated and usually requires two workers. In addition, the ability to direct the spark discharge horn is limited.

Cilj je pronalaska da se otklone navedeni nedostaci i da se ostvari naprava za zaštitu od iskrenja koja će se moći lako i jednostavno ugraditi i kod koje će se rog za odvod iskri moći skinuti ili zamijeniti a da se ne moraju stezaljke rastavljati. The aim of the invention is to remove the mentioned defects and to create a spark protection device that can be easily and simply installed and where the spark discharge horn can be removed or replaced without having to disassemble the clamps.

Ovaj je cilj postignut jednom napravom za zaštitu od iskrenja naprijed navedene vrste tako, što prema pronalasku jedna od stezaljki ima jedan nastavak sa vanjskim navojem, i što rog za odvod iskri ima najednom kraju otvor koji odgovara poprečnom presjeku nastavka, tako da se može pomoću jedne navrtke pričvrstiti na tom produžetku. This goal is achieved by a spark protection device of the aforementioned type in that, according to the invention, one of the clamps has an extension with an external thread, and that the spark discharge horn has an opening at one end corresponding to the cross-section of the extension, so that it can be fasten the nuts on that extension.

Na ovaj način pronalaskom je ostvarena naprava za zaštitu od iskrenja koju jedna jedina osoba može lako i jednostavno ugraditi, koja, s jedne strane, ima jedan nastavak kao lako dostupan držač, a, s druge strane, rog za odvod iskri se može pričvrstiti na stezaljku prije ugradnje naprave za zaštitu od iskrenja, pa se tako može koristiti kao držač. In this way, the invention has achieved a device for protection against sparks that can be easily and simply installed by a single person, which, on the one hand, has an extension as an easily accessible holder, and, on the other hand, a spark discharge horn can be attached to the clamp before installing the spark protection device, so it can be used as a holder.

Druge prednosti pronalaska sastoje se u tome, što se rog za odvod iskri, na primjer, zbog zamjene, može lako skinuti, a da se stezaljke ne moraju razdvajati, što se naprava za zaštitu od iskrenja može koristiti kao odvojna stezaljka ili kao stezaljka za uzemljenje, tako što će se umjesto roga za odvod iskri priključiti pomoću kabelskog nastavka odvojni kabel ili kabel za uzemljenje. Inače se rog za odvod iskri može usmjeriti u bilo kojem pravcu. Other advantages of the invention consist in the fact that the spark arrestor horn can be easily removed, for example for replacement, without having to separate the terminals, that the spark protection device can be used as a disconnecting terminal or as an earthing terminal , so that instead of the spark arrester horn, a separation cable or a grounding cable will be connected using the cable extension. Otherwise, the spark discharge horn can be directed in any direction.

Kod jednog pogodnog izvođenja pronalaska može element za stezanje biti na poznat način izveden kao vijak za pritezanje, a jedna od stezaljki može biti načinjena sa unutrašnjim navojem koji odgovara vanjskom navoju vijka za pritezanje, pri čemu se taj unutrašnji navoj formira u nastavku stezaljke. Ovim se dobiva kompaktna konstrukcija uz uštedu na materijalu. In one suitable embodiment of the invention, the clamping element can be made in a known manner as a tightening screw, and one of the clamps can be made with an internal thread that corresponds to the external thread of the tightening screw, whereby this internal thread is formed in the continuation of the clamp. This results in a compact construction with savings on material.

Dalje je pogodno da stezaljka na kojoj je načinjen nastavak ima u području nastavka površinu nalijeganja za rog za odvod iskri, čime se povećava sigurnost ugradnje. Furthermore, it is convenient for the clamp on which the extension is made to have a contact surface for the spark discharge horn in the area of the extension, which increases the safety of installation.

Najzad se može bar nastavak stezaljke iskovati, čime se poboljšava otpornost na vremenske promjene kao i otpornost na starenje. Finally, at least the extension of the clamp can be forged, which improves resistance to weather changes as well as resistance to aging.

Pronalazak će biti detaljnije objašnjen preko jednog preporučljivog primjera izvođenja prikazanog na priloženim slikama, gdje The invention will be explained in more detail through a recommended embodiment shown in the attached figures, where

- slika 2 prikazuje presjek duž linje II-II na slici 1, a - Figure 2 shows a section along line II-II in Figure 1, a

- slika 3 prikazuje pogled na stezaljku sa nastavkom u smijeru strelice A sa slike 2. - picture 3 shows a view of the clamp with extension in the direction of arrow A from picture 2.

Prema crtežima naprava za zaštitu od iskrenja ima dvije stezaljke 1 i 2, koje se mogu međusobno stegnuti elementom za pritezanje u vidu vijka 3 za pritezanje. Stezaljka 1 ima gladak provrt 4, dok druga stezaljka 2 ima odgovarajući unutrašnji navoj 5. Između stezaljki 1 i 2 načinjen je kanal 6 za prihvat jednog vodiča. U području kanala 6 su obe stezaljke izvedene sa zupcima 11, odnosno 12, čija dužina odgovara debljini izolacijskog sloja vodiča, kako bi mogli probiti izolaciju i uspostaviti električni kontakt. Pogodno je da se između stezaljki 1 i 2 predvidi još jedan kanal 7 za prihvaćanje još jednog vodiča, kao što je jedna vezna žica. According to the drawings, the spark protection device has two clamps 1 and 2, which can be clamped together with a tightening element in the form of a tightening screw 3. Clamp 1 has a smooth bore 4, while the other clamp 2 has a corresponding internal thread 5. Between clamps 1 and 2, a channel 6 is made to accept one conductor. In the area of channel 6, both clamps are made with teeth 11 and 12, the length of which corresponds to the thickness of the insulating layer of the conductor, so that they can break through the insulation and establish electrical contact. It is convenient to provide another channel 7 between terminals 1 and 2 to accept another conductor, such as a connecting wire.

Stezaljka 2 sa unutrašnjim navojem 5 ima na svojoj vanjskoj strani nastavak 8, izveden sa vanjskim navojem 9. Dalje je u području nastavka 8 na stezaljki 2 načinjena površina 10 nalijeganja. The clamp 2 with an internal thread 5 has on its outer side an extension 8, made with an external thread 9. Further, in the area of the extension 8, a contact surface 10 is made on the clamp 2.

Naprava za zaštitu od iskrenja dopunjena je rogom 13 za odvod iskri koji se sastoji od dva pravocrtna dijela koji se međusobno sučeljavaju pod tupim kutom. Kraći odsječak je zaravnjen i načinjen sa otvorom u vidu provrta 14, čiji promjer odgovara promjeru nastavka 8. Rog 13 za odvod iskri naliježe svojim zaravnjenim odsječkom na površinu 10 nalijeganja i pomoću navrtke 15 pričvršćen je na nastavku 8. Ako su površina 10 nalijeganja kao i pripadajuća površina zaravnjenog odsječka roga 13 za odvod iskri ravne, može se rog 13 za odvod iskri usmjeriti u bilo kojem pravcu. The spark protection device is supplemented with a horn 13 for the discharge of sparks, which consists of two straight parts that face each other at an obtuse angle. The shorter section is leveled and made with an opening in the form of a hole 14, the diameter of which corresponds to the diameter of the attachment 8. The horn 13 for the spark discharge rests with its leveled section on the bearing surface 10 and is attached to the attachment 8 using a nut 15. If the bearing surface 10 as well as corresponding surface of the flattened section of the horn 13 for spark discharge is flat, the horn 13 for spark discharge can be directed in any direction.

Ako se želi, može se uvijek umjesto roga 13 za odvod iskri preko kabelske spone priključiti jedan odvojni kabel ili kabel za uzemljenje. If desired, instead of the horn 13 for the spark discharge, a separate cable or grounding cable can always be connected via the cable clamp.

Kod ugradnje naprave za zaštitu od iskrenja, pogodno je da se rog 13 za odvod iskri pričvrsti na pripadajuću stezaljku 2, tako da se dobiva element za držanje koji omogućuje dobro rukovanje. When installing the device for protection against sparks, it is convenient to attach the horn 13 for spark discharge to the associated clamp 2, so that a holding element is obtained that enables good handling.

Ukoliko treba zamijeniti rog 13 za odvod iskri, to se može uraditi a da se ne vrši razdvajanje stezaljki 1 i 2. If the spark arrestor horn 13 needs to be replaced, it can be done without disconnecting terminals 1 and 2.
