Description

Područje tehnike u koje spada izum The technical field to which the invention belongs

Izum se odnosi na samonosivi telefonski ormarić, koji je namijenjen za primjenu kod izgradnje telefonske mreže, odnosno za završavanje i prespajanje primarnog kabela na sekundarne-pretplatničke kabele. The invention relates to a self-supporting telephone cabinet, which is intended for use in the construction of a telephone network, i.e. for terminating and connecting the primary cable to the secondary subscriber cables.

Takvi izumi su prema Međunarodnoj klasifikaciji patenata (MKP) uvršteni u područje elektrotehnike, te radi toga ulaze u razred H02G 15/076 ili H02G 15/013. According to the International Classification of Patents (IPC), such inventions are included in the field of electrical engineering, and for that reason they enter the class H02G 15/076 or H02G 15/013.

Tehnički problem Technical problem

Izum se temelji na problemu kako napraviti samonosivi telefonski ormarić, koji će biti: optimalnih dimenzija, jednostavan za montažu, otporan na sve atmosferske uvjete, te koji će sprečavati prodor vlage u unutrašnjost i njeno agresivno djelovanje na spojna mjesta u kućištu. Ujedno je bitno da ormarić bude konstrukcijski izveden tako da omogućava dobar pristup kod spajanja kabela u ormariću. The invention is based on the problem of how to make a self-supporting telephone cabinet, which will be: optimal dimensions, easy to assemble, resistant to all atmospheric conditions, and which will prevent the penetration of moisture into the interior and its aggressive effect on the connection points in the housing. At the same time, it is important that the cabinet is constructed in such a way that it allows good access when connecting the cables in the cabinet.

Stanje tehnike State of the art

Poznata je naprava za spajanje i račvanje instalacijskih kabela, posebice za završno račvanje spojne kutije ili razdjelne kutije za telekomunikacijske kablove, koja u donjem dijelu kućišta ima smještene uvodnike kabela koji imaju po dvije rasklopne brtveno/pričvrsne polovice za polaganje jednog kabela. Obje sklopive polovice za brtvljenje i pričvršćivanje mogu formiranjem brtveno/pričvrsne jedinice s brtvom i pričvrsnicom primiti u donjem dijelu kućišta kabel, sprijeda uguran u držač, te se time postiže brtvljenje i pridržavanje kabela. Osnovni nedostatak spomenutog uređaja je taj da ne postoji mogućnost uvođenja više ulaznih kabela različitih promjera, te je problematično postavljanje gore navedene naprave na terenu jer nema nosivu cijev za prolaz kabela koju predmetni izum ima. Gumena brtva sa više konusnih izdanaka u različitim veličinama otklanja gore spomenuti nedostatak priključenja više kabela različitih dimenzija, a ujedno je jednostavnija po konstrukciji uz jednaku djelotvornost brtvljenja. It is a well-known device for connecting and splitting installation cables, especially for the final splitting of a junction box or distribution box for telecommunication cables, which has cable inlets located in the lower part of the housing, which each have two detachable sealing/fixing halves for laying one cable. Both folding halves for sealing and fixing can, by forming a sealing/fastening unit with a seal and a fastener, receive the cable in the lower part of the housing, pushed into the holder from the front, thus achieving sealing and holding the cable. The main disadvantage of the mentioned device is that there is no possibility of introducing multiple input cables of different diameters, and it is problematic to set up the above-mentioned device in the field because it does not have a supporting tube for the passage of cables, which the invention in question has. The rubber seal with multiple conical protrusions in different sizes eliminates the above-mentioned disadvantage of connecting multiple cables of different dimensions, and at the same time, it is simpler in construction with the same sealing effectiveness.

Opis rješenja tehničkog problema sa primjerom izvođenja Description of the solution to the technical problem with an example of implementation

Prethodno navedeni tehnički problem je riješen sa samonosivim telefonskim ormarićem, čija je konstrukcija tako izvedena da se sastoji od jednodijelnog kućišta koje se zatvara i otvara preklapanjem poklopca ormarića oko gibljive spojnice od gume, a nalazi se učvršćeno na cijevi za prolaz kabela ukopanom u zemlju. Dio cijevi ukopan u zemlji je još dodatno učvršćen obujmicama na sondu koja je potpuno ukopana u zemlju. Gumena brtva na spoju cijevi sa kućištem ormarića sprječava prodor vlage u unutrašnjost kućišta, a omogućava spajanje više ulaznih kabela različitih debljina. The previously mentioned technical problem was solved with a self-supporting telephone cabinet, the construction of which is made in such a way that it consists of a one-piece housing that closes and opens by folding the cabinet cover around a flexible rubber joint, and is fixed on a pipe for the cable passage buried in the ground. The part of the pipe buried in the ground is additionally fixed with clamps on the probe, which is completely buried in the ground. The rubber seal at the connection between the pipe and the cabinet housing prevents moisture from entering the inside of the housing, and enables the connection of several input cables of different thicknesses.

Kao što je vidljivo na slikama 1, 2, 3 i 7 kućište samonosivog telefonskog ormarića je sastavljeno iz dva dijela : poklopca (1) i nosećeg dijela (2) koji su međusobno spojeni elastičnom gumom (3) koja osigurava dobro brtvljenje od prolaza vlage u unutrašnjost kućišta, a ujedno i lagano podizanje poklopca (1) i njegovo preklapanje preko nosećeg dijela (2). Elastična guma (3) ima prvenstveno funkciju gibljive spojnice poklopca (1) i nosećeg dijela (2), a zalivena je i uprešana u za to predviđene pozicije na njima. Kućište je spojeno na noseću cijev (4) kroz koju prolazi kabel. Na ulazu noseće cijevi (4) u kućište ormarića nalazi se gumena brtva (5) čija je namjena sprječavanje prodora vlage u unutrašnjost ormarića. As can be seen in pictures 1, 2, 3 and 7, the case of the self-supporting telephone cabinet is composed of two parts: the cover (1) and the supporting part (2), which are connected to each other by elastic rubber (3), which ensures good sealing against the passage of moisture in the inside of the case, and at the same time slightly lifting the cover (1) and folding it over the supporting part (2). The elastic rubber (3) has primarily the function of a flexible joint of the cover (1) and the supporting part (2), and it is filled and pressed into the positions provided for it. The housing is connected to the support tube (4) through which the cable passes. There is a rubber seal (5) at the entrance of the carrier pipe (4) to the cabinet housing, the purpose of which is to prevent the penetration of moisture into the interior of the cabinet.

Noseća cijev (4) se pri montaži ukopava u zemlju sa približno 2/5 svoje duljine, gdje je obujmicama (6) pričvršćena za sondu (7) koja je potpuno zabijena u zemlju i učvršćuje cijelu konstrukciju telefonskog ormarića. Ormarić se otvara i zatvara pomoću posebnog ključa koji odgovara završetku profila glave vijka (8) oblika trostrane prizme, smještenog u donjem dijelu poklopca (1), tako da je pristup u unutrašnjost moguća samo ovlaštenim osobama. During assembly, the supporting pipe (4) is buried in the ground with approximately 2/5 of its length, where it is attached with clamps (6) to the probe (7), which is completely driven into the ground and secures the entire structure of the telephone cabinet. The cabinet is opened and closed using a special key that corresponds to the end of the profile of the screw head (8) in the shape of a three-sided prism, located in the lower part of the cover (1), so that access to the interior is only possible for authorized persons.

Na slikama 5 i 6 se vidi da je gumena brtva (5) valjkastog oblika, a sastoji se od konusnih izdanaka (9) i gumenog obruba (10). Figures 5 and 6 show that the rubber seal (5) is cylindrical in shape, and consists of conical protrusions (9) and a rubber rim (10).

Gumeni obrub (10) ima na svojoj površini nekoliko izbočina (15) koje predstavljaju dodatnu prepreku prodoru vlage. Konusni izdanci (9) se nalaze na gornjoj plohi gumene brtve (5) i zatvoreni su tankim slojem gume koju je potrebno otkinuti prije uvlačenja kabela, da bi konusni izdanak (9) čvrsto prionuo uz kabel i tako onemogućio prodor vlage. Konusni izdanci (9) su različitih veličina ovisno o veličini kabela i poredani su tako da oni istog promjera čine vrhove kvadrata smještenih na raznim promjerima gornje strane brtve (6). The rubber border (10) has several protrusions (15) on its surface, which represent an additional barrier to the penetration of moisture. The conical protrusions (9) are located on the upper surface of the rubber seal (5) and are closed with a thin layer of rubber, which must be torn off before inserting the cable, so that the conical protrusion (9) adheres firmly to the cable and thus prevents the penetration of moisture. The conical protrusions (9) are of different sizes depending on the size of the cable and are arranged so that those of the same diameter form the tops of the squares located on different diameters of the upper side of the seal (6).

Kao što se vidi na slici 4 na noseći dio (2) ormarića učvršćena je sa dva pričvrsna vijka (11) temeljna ploča (12) na koju se pričvršćuju razni tipovi letvica (13) (npr. PL21 za 40 parica, KLIO za 50 parica ili KRONE kapaciteta 100 parica i sl.). Temeljna ploča (12) je perforirana, odnosno izvedena je sa malim provrtima poredanim jedan pored drugoga, te je stoga vrlo jednostavno pričvršćivanje dodatnih letvica (13). U gornjem dijelu temeljne ploče (12) nalazi se sabirnica uzemljenja (14) pomoću koje se zemljovodom do zemljovodnog tijela vrši uzemljenje svih kabela u ormariću. As seen in Figure 4, the base plate (12) is fixed to the supporting part (2) of the cabinet with two fastening screws (11), on which various types of slats (13) are attached (e.g. PL21 for 40 pairs, KLIO for 50 pairs or KRONE with a capacity of 100 coins, etc.). The base plate (12) is perforated, i.e. it is made with small holes arranged next to each other, and therefore it is very easy to attach additional slats (13). In the upper part of the base plate (12) there is a grounding bus (14), which is used to ground all the cables in the cabinet through the ground wire to the grounding body.
