Description

Przedmiotem niniejszego wynalazku jest dalsze ulepszenie elektrycznego kabla kontaktowego opisanego w patencie Nr 8178 dotyczace tych kabli, których przewo¬ dy sa od siebie oddzielone zapomoca ela¬ stycznych wkladek izolujacych.Wspomniane wkladki sa w mysl niniej¬ szego wynalazku wykonane w ten sposób, ze przy nacisnieciu kabla w dowolnem miejscu splaszczaja sie o tyle, aby'przewo¬ dy kabla mogly sie zetknac ze soba, przy- czem wkladki te sa ciagle na calej dlugo¬ sci kabla i sa zaopatrzone w naciecia, wy¬ kroje, lub otwory. Pirzewody moga lezec w tych nacieciach lub wykrojach, albo tez moga sie znajdowac w otworach wkladek naprzeciwko siebie, tak ze naciskajac ka¬ bel w dowolnem miejscu mozna spowodo¬ wac zetkniecie sie przewodów kabla. W ce¬ lu ulatwienia styków przewodów kabla i ze¬ by kontakt byl pewniejszy, mozna zaopa¬ trzyc przewody w zgrubienia rozmieszczo¬ ne w ten sposób, zeby sie znajdowaly na¬ przeciwko wciec, wykrojów lub otworów wkladek.W pewnych wykonaniach kabla kontak¬ towego w mysl glównego patentu przewody sa 'prowadzone wzdluz osi kabla, czyli kon¬ centrycznie; te zasadnicza forme mozna je¬ szcze rozwinac.Wkladka moze np. otaczac przewód lub przewody wewnetrzne kabla. Zgrubie-nia przewodów moga byc wykonane w ten sposób, ze przewody zostaja srubowo okre¬ cone drutem. Ewentualnie sam przewód wewnetrzny moze byc srubowo wkrecony i nawiniety ewentualnie na rdzen nieprzc- wodzacy elektrycznosci. Wkladka moze byc wykonana w postaci np. paska, tasmy \Jffb s^ujk, av^iietego srubowo okolo prze- ^yfodni^b^h^%dóv/ wewnetrznych w ten sposób, ze pomiedzy poszczególnemi zwo¬ jami pozostaja wolne szczeliny, umozliwia¬ jace kontakt przewodów kabla.Zwoje srubowo zwinietej wkladki mo¬ ga wchodzic pomiedzy zgrubienia we¬ wnetrznego przewodu, wzglednie pomiedzy zwoje srubowo okreconego drutu i w tym przypadku srednica zwoju wkladki musi byc wieksza od srednicy zwoju drutu. Ze¬ wnetrzny przewód moze byc wykonany w postaci plaszcza, skladajacego sie z szere¬ gu szczelnie obok siebie lezacych drutów, zwinietych równiez srubowo. Pomiedzy ze¬ wnetrzny przewód i plaszcz kabla mozna wstawic jeszcze specjalna wkladke np, z papieru.Wkladka zawiera zawsze celowo jakis materjal wlóknisty, który unosi jej spre¬ zystosc w jednym albo w kilku kierunkach, czesciowo lub calkowicie, Materjalem wlók¬ nistym moga byc np, nici, sznury lub tka¬ niny, znajdujace sie wewnatrz wkladki lub na niej.Na rysunku, przedstawiono przyklad wykonania kabla dwuzylowego.Jeden przewód a przechodzi wzdluz o- si kabla i sklada sie z kilku drutów skre¬ conych z soba i nawinietych ewentualnie na rdzen nieprzewodzacy elektrycznosci. Do¬ kola tego przewodu sa nawiniete srubowo obok siebie drut 6 i tasma d z miekkiej gu¬ my lub z innego materjalu elastycznego i izolujacego, grubsza od drutu 6. Zewnetrz¬ ny przewód e sklada sie z kilku drutów le¬ zacych szczelnie obok siebie i przebiegaja¬ cych równiez srubowo, opierajacych sie na zwojach tasmy d. Pomiedzy przewodem e i elastycznym plaszczem g kabla znajduje sie wkladka /, np, z papieru, W stanie spoczynku tasma d (patrz przekrój dolnej czesci kabla przedstawio¬ nego na rysunku) niedopuszcza do zetknie¬ cia sie obu przewodów. Jezeli jednak na¬ cisnac kabel w dowolnem miejscu, to tasma d rozplaszcza sie i wtedy zewnetrzny prze¬ wód e moze sie zetknac z drutem 6 owinie¬ tym na wewnetrznym przewodzie a, wsku¬ tek czego obwód pradu zostaje zamkniety.Gdy nacisk na kabel ustanie, to sprezysta tasma d odsuwa znowu od siebie przewody kabla.Wspomniano juz wyzej, ze tasma d za¬ wiera materjaly wlókniste, najlepiej w po¬ staci tasmy, której plaszczyzna lezy w go¬ towym kablu równolegle do jego plaszczyzn naciskowych. PL PLThe object of the present invention is a further improvement of the electric contact cable described in Patent No. 8178 relating to those cables whose conductors are separated from each other by means of elastic insulating plugs. According to the present invention, said plugs are made in such a way that when pressed of the cable, they flatten at any point so that the conductors of the cable can touch each other, with these inserts being continuously over the entire length of the cable and provided with cuts, cuts, or holes. The conductors may lie in these cuts or blanks, or they may be in the openings of the inserts facing each other, so that by applying pressure to the cable at any point, the conductors of the cable may come into contact. In order to facilitate the contacts of the cable conductors and to make contact more secure, the conductors may be provided with beads arranged so that they face the connectors, blanks or holes of the inserts. according to the main patent, the wires are guided along the axis of the cable, ie concentrically; this basic form can still be expanded. The insert may, for example, encircle the conductor or the inner conductors of the cable. The thickenings of the conductors may be made in such a way that the conductors are spiked with a wire. Alternatively, the inner conductor itself can be screwed in screws and possibly wound on an electrically non-conductive core. The insert can be made in the form of, for example, a strip, tapes \ Jffb s ^ s ^ openings, and roughly around the flow rate ^ b ^ h ^% of the inside ends in such a way that there are free gaps between the individual turns, it allows The coils of the coiled cable may be inserted between the thickening of the inner conductor, or between the coils of the helically defined wire, and in this case the diameter of the coils of the plug must be greater than the diameter of the coils of the wire. The inner conductor may be made in the form of a sheath, consisting of a series of closely adjoining wires, also coiled in helical form. A special insert, e.g. made of paper, can be inserted between the inner conductor and the sheath of the cable. The insert always deliberately contains some fibrous material, which raises its elasticity in one or several directions, partially or completely. The fiber material can be e.g. , threads, cords or fabrics inside or on the insert. The figure shows an example of a two-core cable. One conductor runs along the axis of the cable and consists of several wires twisted together and possibly wound on non-conductive core. The bottom of this conductor is coiled next to each other by a wire 6 and a strip of soft rubber or other flexible and insulating material, thicker than wire 6. The outer conductor consists of several wires lying tightly next to each other and running alongside each other. There is an insert /, e.g., made of paper, between the cable e and the flexible sheath g of the cable, also in the form of a screw, based on the coils of the tape. When idle, the tape d (see the cross section of the lower part of the cable shown in the figure) prevents contact connect both wires. However, if you press the cable anywhere, the tape d unfolds and the outer conductor may come into contact with the wire 6 wrapped on the inner conductor, thereby closing the circuit of the current. When the pressure on the cable is released. it is the elastic tape d that again pushes the wires of the cable apart. It has already been mentioned above that the tape d contains fibrous materials, preferably in the form of a tape, the plane of which lies in the finished cable parallel to its pressure planes. PL PL
