Description

Zestaw koncówek elektrycznych srubowych Przedmiotem wzoru przemyslowego jest zestaw koncówek elektrycznych srubowych,skladajacy sie z koncówki elektrycznej srubowej z jedna sruba i koncówki elektrycznej srubowej z dwoma srubami. Koncówki wedlug wzor u przemyslowego maja ksztalt plaskiego walca z otworem, polaczonego z tuleja. Powierzchnia zewnetrzn a koncówki jest gladka,a powierzchnia wewnetrzna tulei ma naciety gwint sluzacy do przebicia tlenków wystepujacych na powierzchniach laczonych przewodów. Koncówki wykonane sa ze stopu aluminiowego i pokryte sa powloka cyno wa.Sruby zrywalne wykonane sa z mosiadzu cynowego i maja naciete ro wki na powierzchni zewnetrznej gwintowanej. Koncówki maja zastosowanie do laczenia przewodów aluminiowych i miedzianych, jednodrutowych, wi e lodrutowych i sektorowych o napieciu do 36 kV w mufach. Koncówki wedlug wzoru,uwidocznione sa na rysunku na którym fig. 1 przedstawia koncówke z jedna sruba w widoku,fig.2 przedstawia kon cówke z jedna sruba w przekroju wzdluznym,fig.3,przedstawia koncówke . z-Ay/oma srubami w widoku _a j3.g* 4, przedstawia koncówke z dworna sruba mi w przekroju wzdluznym. Cechy istotne wzoru przemyslowego: - koncówki wedlug wzoru przemyslowego maja ksztalt plskiego walca z otworem polaczonego z tuleja pod katem 90 miedzy osiami otworów. —koncówki wykonane sa ze stopu aluminium i pokryte powloka cynowa. - koncówki maja gladka powierzchnie zewnetrzna,a na powierzchni wew netrznej tulei maja naciety gwint, - sruby zrywalne wykonane sa z mosiadzu cynowego i maja naciete row ki na powierzchni zewnetrznej gwintowanej.Fig.1 Fig.2Fig.3 Fig.4Fig.1 Fig.3 PL PLSet of Screw-Type Electrical Terminals. The industrial design covers a set of screw-type electrical terminals, consisting of a screw-type electrical terminal with one screw and a screw-type electrical terminal with two screws. According to the industrial design, the terminals are shaped like a flat cylinder with a hole, connected to a sleeve. The outer surface of the terminal is smooth, while the inner surface of the sleeve has a cut thread used to penetrate oxides present on the surfaces of the connected wires. The terminals are made of aluminum alloy and are tin-plated. The shear bolts are made of tin-plated brass and have cut grooves on the outer threaded surface. The terminals are used for connecting aluminum and copper conductors, solid, solid, and sector-shaped, with voltages up to 36 kV, in joints. The terminals according to the design are shown in the drawing, where Fig. 1 shows a terminal with a single screw in view; Fig. 2 shows a terminal with a single screw in longitudinal cross-section; Fig. 3 shows a terminal with two screws in view _a j3.g*; and Fig. 4 shows a terminal with two screws in longitudinal cross-section. Significant features of the industrial design: - the terminals according to the industrial design have the shape of a flat cylinder with a hole connected to a sleeve at a 90° angle between the hole axes. - the terminals are made of an aluminum alloy and tin-plated. - the tips have a smooth outer surface and a thread cut on the inner surface of the sleeve, - the shear bolts are made of tin brass and have grooves cut on the outer threaded surface.
