Description

STIKALNA ALI LOČILNA LETEVSWITCH OR SEPARATION BAR

Izum spada v področje stikalnih sestavnih delov za telekomunikacijsko tehniko. Predmet izuma je uvrščen v razreda H 01 R 13/713 in H 01 R 13/648 mednarodne patentne klasifikacije.The invention is within the scope of telecommunication switching components. The subject matter of the invention is classified in classes H 01 R 13/713 and H 01 R 13/648 of the international patent classification.

Znane so stikalne ali ločilne letve telekomunikacijske tehnike, opremljene z zbirno ozemljitvijo.Known switchgear or switchgear strips for telecommunications equipment equipped with collector earthing.

Iz P 37 09 875.6-34 je znana letev te zvrsti. Ta sestoji iz dveh pollupin ohišja, v katerih notranjem prostoru je nameščen zaščitni hibrid z dvema vzporednima vodniškima progama. Vodniški progi sta povezani prek vodniških kontaktov z a-b žilami oz. a’-b’ žilami telekomunikacijskega voda. Nadalje so nameščeni drug poleg drugega ležeči prenapetostni odvodniki, ki so vpeti med vodniškimi progami zaščitnega hibrida in ozemljitveno pločevino. Pod zaščitnim hibridom nameščena ozemljitvena pločevina vsebuje za pričvrstitev prenapetostnih odvodnikov dva prožna pločevinasta jezika, ki sta za tvorbo sponk U-oblike kotno zapognjena prečno k vzdolžnim stranem ozemljitvene pločevine. Da bi se povezalo prenapetostne odvodnike z ozemljitvijo, sta potrebna dva nadaljnja pločevinasta jezhika. Ta pločevinasta jezika obsegata vsakokrat po en krak, ki je nameščen v razmiku od vodniških prog. Pri tem zaščitnem vtiču je pomanjkljivo, da je z namestitvijo dveh drug poleg drugega ležečih prenapetostnih odvodnikov in zaradi ozemljitvene pločevine, ki obsega več pločevinastih jezikov, širina in debelina ohišja občutno povečana. Pri vtiku zaščitnega vtiča v stikalno ali ločilno letev je s tem ranžirna stran letve pokrita, tako da se mora za priključitev in odstranitev (ranžiranje) kabelskih žil zaščitni vtič najprej izvleči. Nadaljnja pomanjkljivost sestoji v tem, da je ohišje zaščitnega vtiča izoblikovano dvodelno.From P 37 09 875.6-34 the lath of this genus is known. This consists of two housing groups in which an enclosure with two parallel guide lines is housed inside. The conductor lines are connected via a-b conductor contacts. a'-b 'veins of telecommunication line. In addition, adjacent overvoltage arresters are mounted adjacent to each other between the conductor lines of the protective hybrid and the ground plane. Below the protective hybrid, the earthing sheet contains two flexible sheet metal tongs for attaching the surge arresters, which are angularly bent transversely to the longitudinal sides of the earthing sheet to form U-shaped clips. In order to connect surge arresters to ground, two further tin bushes are required. These sheet metal tongues each comprise one arm spaced apart from the guide lines. It is not a disadvantage of this protective plug that the width and thickness of the housing are significantly increased by installing two adjacent overvoltage arresters and by a grounding plate comprising several sheet metal tongues. When the protective plug is inserted into the switch or separation strip, the shunt side of the lath is thus covered, so that the protective plug must first be pulled out to connect and remove (shunt) the cable veins. A further disadvantage is that the housing of the protective plug is formed in two parts.

Izum ima zato za nalogo, da ustvari stikalno ali ločilno letev te zvrsti, katere ohišje je izoblikovano kar najmanjše in pri katere uporabi naj bodo na ranžirni strani stikalne ali ločilne letve priključeni kabli dostopni tudi po vtiku zaščitnega vtiča.The invention therefore has the task of creating a switch or disconnecting strip of this type, the housing of which is designed as small as possible, and in which use the cables connected to the shunting or disconnecting strip are accessible even after the plug of the protective plug.

Rešitev te naloge je podana z označujočimi značilnostmi zahtevka 1. Prenapetostni odvodniki se dovedejo v stik z zbirno ozemljitvijo šele po natiku zaščitnega vtiča na stikalno ali ločilno letev, s čemer je vzpostavljena ozemljitvena povezava. Po izumu je zbirna ozemljitev nameščena izven ohišja zaščitnega vtiča, s čemer je ohišje oblikovano občutno zmanjšano. Z zmanjšanjem ohišja zaščitnega vtiča soThe solution to this problem is given by the characterizing features of claim 1. Surge arresters are only contacted by collector grounding after the protective plug is applied to a switch or separation strip, thereby establishing a ground connection. According to the invention, the collecting earthing is located outside the housing of the protective plug, thereby significantly reducing the housing design. By reducing the housing of the protective plug they are

- 3 na ranžirni strani priključene kabelske žile stikalne ali ločilne letve dostopne tudi po natiku zaščitnega vtiča, tako da so možna ranžiranja, npr. sprostitev že priključenih kabelskih žil, tudi brez odstranitve zaščitnega vtiča. Prek * tega je zaščitni vtič zgrajen z enodelnim ohišjem, tako da se lahko izdeluje zaščitni vtič občutno ceneje.- 3 on the shunt side of the connected cable core of the switch or stripper can also be accessed after the plug has been inserted so that shunting is possible, e.g. release of already attached cable veins, even without removing the protective plug. Through this, the protective plug is built with a one-piece housing so that the protective plug can be made significantly cheaper.

Nadaljnja prednostna oblikovanja izuma so razvidna iz podzahtevkov. Pri te se opozarja posebno na izvedbeno obliko po zahtevku 6, 7 in 8, pri čemer imajo uhlji zbiralne ozemljitve za kontaktiranje prenapetostnih odvodnikov samoFurther preferred embodiments of the invention are apparent from the sub-claims.

Da bi se uvajanje olajšalo, so jeziki 11 pri tej izvedbeni * obliki na čelni strani 46 nekoliko zapognjeni.In the third embodiment (FIGS. 12 to 16), the conductors 11 are pushed into the plug channel 48 below the restraining bridges 24, as shown in FIG. 12, when the plug 1 is inserted. In order to facilitate deployment, the tongues 11 in this embodiment * are slightly bent on the front face 46.

Pri četrti izvedbeni obliki (sl.17 in 18) so jeziki 11 oblikovani glede na prej opisane izvedbene oblike skrajšano, ker se mora dovesti jezik 11 pri izvedbeni obliki v električno povezavo samo s pločevinastim delom 50. Za vodilo jezika 11 je predviden na vzdolžnih straneh 8 ohišja 2 vsakokrat vodilni kotnik 53, tako da je v vtičnem kanalu 48 nameščen jezik 11 zbirne ozemljitve 5 med vodilnimi kotniki 53 in pločevinastim delom 50.In the fourth embodiment (Figs. 17 and 18), the tongues 11 are formed relative to the previously described embodiments, since the tongue 11 in the embodiment is to be electrically connected only to the sheet metal part 50. The tongue 11 is provided on the longitudinal sides. 8 of the housing 2, each is a guide angle 53, so that the tongue 11 of the collecting earth 5 is inserted between the guide angles 53 and the sheet part 50 in the plug channel 48.

Če je na vzdolžnih straneh 8 povezanih drug ob drugem več zaščitnih vtičev 1, potem se tvori letev 31 zaščitnih vtičev.If several safety plugs 1 are connected to each other along the longitudinal sides 8, then a bar 31 of safety plugs is formed.

V nadaljevanju bo na kratko pojasnjen primer prenapetosti. Če nastopi prenapetost, potem se odvede prenapetost oz. prekomeren tok prek kabelskih žil 38, 39, reznosteznih kontaktov 40, 41, viličastega kontakta 47, vodniških kontaktov 13, 14, talilne tablete 30 k eni strani 29 pola prenapetostnega odvodnika 3V prenapetostnem odvodiku 3, napolnjenim z žlahtnim plinom, nastopi vžig, zaradi česar se dovede prenapetost k drugemu polu 28 prenapetostnega odvodnika 3, ki je električno povezan z zbirno ozemljitvijo 5. Prenapetost se dovede s tem prek viličastih kontaktov 41 in zbirne ozemljitve 5 k montažnemu locnu 36, ki je povezan z ožemijitvenim vodnikom.The example of overvoltage will be briefly explained below. If an overvoltage occurs, then the overvoltage or voltage is removed. over current through cable veins 38, 39, resistance contacts 40, 41, fork contact 47, conductor contacts 13, 14, melting tablets 30 to one side 29 of the overvoltage arrester 3 In the overvoltage drain 3 filled with noble gas, causing ignition an overvoltage is applied to the second pole 28 of the overvoltage arrester 3, which is electrically connected to the collector earthing 5. The overvoltage is thereby brought through the forked contacts 41 and the collector earthing 5 to the mounting strip 36, which is connected to the earth conductor.

Pri trajajočem vžigu prenapetostnega odvodnika se zaradi nastajajoče toplote raztali talilna tableta 30, s čemer pride do. kontakta med vzmetnim kratkostičnim locnom *With the continuous ignition of the surge arrester, the melting tablet 30 melts due to the resulting heat, resulting in. of contact between spring short circuit *

25, 26 in jezikom 11 zbirne ozemljitve 5 oz. s pločevinastim delom 50, ki je povezan z zbirno ozemljitvijo 5 in do premostitve prenapetostnega odvodnika 3 (Fail-Safe-ponašanje). S tem je preprečeno uničenje zaščitnega vtiča 1 s pregrevanjem.25, 26 and language 11 of the cumulative grounding 5 and with a sheet metal part 50 connected to the collector grounding 5 and to a surge arrester 3 (Fail-Safe behavior). This prevents the plug 1 from being destroyed by overheating.
