Podľa ďalšieho výhodného uskutočnenia spoluzaberajú závity upevňovacej skrutky s pozdĺžnym nosníkom, vyčnievajúcim zo spodnej strany koncovky.According to a further preferred embodiment, the threads of the fastening screw co-engage a longitudinal beam protruding from the underside of the terminal.
Prehľad obrázkov na výkreseOverview of the figures in the drawing
Príkladné uskutočnenia koncovky alebo spojovacej svorky sú znázornené na pripojenom výkrese, kde obr. 1 znázorňuje koncovku alebo spojovaciu svorku podľa vynálezu v reze, obr. 2 znázorňuje koncovku alebo spojovaciu svorku z obr. 1 v pôdoryse a obr. 3 znázorňuje koncovku alebo spojovaciu svorku z obr. 1 s iba jedným párom čeľustí, ktoré majú medzi sebou drôt.Exemplary embodiments of the terminal or connection terminal are shown in the accompanying drawing, wherein FIG. 1 is a cross-sectional view of a terminal or connection clamp according to the invention, FIG. 2 shows the terminal or connection clamp of FIG. 1, and FIG. 3 shows the terminal or connection clamp of FIG. 1 with only one pair of jaws having a wire between them.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Koncovka alebo spojovacia svorka pozostáva z dvoch párov protiľahlých čeľustí 1, 2 vybavených zubami na prenikanie izoláciou. Dolné čeľuste 1 ležia v spodnej časti čeľusťového prvku, ktorý je axiálne spojený dolným rozperným prvkom 3 s pozdĺžnym nosníkom 6 vybaveným závitovým otvorom, do ktorého je zaskrutkovaná upevňovacia skrutka 5.The terminal or connection clamp consists of two pairs of opposing jaws 1, 2 provided with teeth for penetrating the insulation. The lower jaws 1 lie in the lower part of the jaw element, which is axially connected by the lower spacer element 3 to the longitudinal beam 6 provided with a threaded hole into which the fastening screw 5 is screwed.
Upevňovacia skrutka 5 má svoj horný koniec vybavený šesťhrannou hlavou 7, ktorá je uložená vo výreze, vytvorenom v izolačnom bloku 8. Inými slovami, časť izolačného bloku 8 tvorí izolačnú vrstvu 9 obklopujúcu hlavu 7 upevňovacej skrutky 5. Izolačná vrstva 9 je obklopená šesťhranným kovovým puzdrom 10, ktoré zároveň obklopuje tiež momentovú maticu 11 pod jej zlomovou čiarou 12. Krútiaca sila sa teda z momentovej matice 11 prenáša na hlavu 7 upevňovacej skrutky 5 pomocou tohto kovového puzdra 10 a izolačnej vrstvy 9. Momentová matica 11 je elektricky izolovaná od šesťhrannej hlavy 7 upevňovacej skrutky 5. Zlomová čiara momentovej matice 11 môže byť tvorená obvodovou drážkou 12 na presné stanovenie požadovanej veľkosti momentu, pri ktorom dôjde k odlomeniu momentovej matice 11.The fastening screw 5 has an upper end provided with a hexagon head 7 which is housed in a cutout formed in the insulating block 8. In other words, part of the insulating block 8 forms an insulating layer 9 surrounding the head 7 of the fastening screw 5. The insulating layer 9 is surrounded by a hexagonal metal sleeve. The torque is thus transmitted from the torque nut 11 to the head 7 of the fastening screw 5 by means of this metal sleeve 10 and the insulating layer 9. The torque nut 11 is electrically insulated from the hexagon head 7 5. The break line of the torque nut 11 may be formed by a circumferential groove 12 to accurately determine the desired torque at which the torque nut 11 breaks.
Uťahovaním upevňovacej skrutky 5 otáčaním matice 11 nad zlomovou čiarou 12 ťahajú závity upevňovacej skrutky 5 spodné čeľuste 1 nahor prostredníctvom dolného rozperného prvku 3 a pozdĺžneho nosníka 6. Horné čeľuste 2 sa oprú o hlavu 7 upevňovacej skrutky 5 prostredníctvom horného rozperného prvku 4. Horné čeľuste 2 a ich horný rozperný prvok 4 sú vybavené dostatočne voľným otvorom, aby sa mohli nakloniť, ako je znázornené na obr. 3. To umožňuje spojenie drôtov s rôznou hrúbkou. Horné čeľuste 2 sú pridržiavané vo svojej hornej polohe pomocou vačiek 16, zachycujúcich konce puzdra alebo krytu 13. Tieto vačky 16 nie sú vystavené podstatnému namáhaniu, ale ich funkciou je iba zabrániť tomu, aby horné čeľuste 2 spadli dole a umožniť ľahké zasunovanie drôtov medzi páry čeľustí 1 a 2. V koncoch krytu 13 sú vytvorené otvory 15 na zasunutie drôtu. Obrázok 3 znázorňuje iba hornú časť puzdra alebo krytu 13. Izolačná vrstva 9 je vytvorená vcelku s prvkom 8 v tvare viečka, ktoré uzaviera otvor vytvorený v hornej strane krytu 13 koncovky. Tento otvor je dostatočne veľký, aby sa horná polovica krytu 13 koncovky mohla nakloniť vzhľadom na upevňovaciu skrutku 5, ako je znázornené na obr. 3.By tightening the fastening bolt 5 by turning the nut 11 above the break line 12, the threads of the fastening bolt 5 lower the jaws 1 upwardly through the lower spacer 3 and the longitudinal beam 6. The upper jaws 2 rest against the head 7 of the fastening bolt 5 through the upper spacer 4. and their upper spacer element 4 is provided with a sufficiently free opening to tilt as shown in FIG. 3. This makes it possible to connect wires of different thicknesses. The upper jaws 2 are held in their upper position by means of cams 16 engaging the ends of the housing or cover 13. These cams 16 are not subjected to substantial stress, but only function to prevent the upper jaws 2 from falling down and allowing wires to slide easily between pairs. The jaws 1 and 2 are provided at the ends of the cover 13. Figure 3 shows only the upper part of the housing or cover 13. The insulating layer 9 is formed integrally with the cap-shaped element 8 which closes the opening formed in the upper side of the terminal cover 13. This opening is large enough that the upper half of the terminal cover 13 can be tilted with respect to the fastening screw 5, as shown in FIG. Third
Sotva je koncovka alebo spojovacia svorka upevnená na svojom mieste a momentová matica 11 sa pozdĺž zlomovej čiary 12 odlomí, môže sa horný otvor krytu 13 uzavrieť viečkom 14. Toto viečko 14 nemôže byť uložené na svoje miesto, dokiaľ sa momentová matica 11 neodlomí. Spoj môže byť tiež ľahko rozobratý odstránením viečka 14 a odskrutkovaním matice tvorenej mnohouholníkovým kovovým puzdrom 10.As soon as the terminal or connection clamp is fixed in place and the torque nut 11 breaks along the break line 12, the upper opening of the cover 13 can be closed by the cap 14. This cap 14 cannot be put in place until the torque nut 11 breaks. The joint can also be easily disassembled by removing the cap 14 and unscrewing the nut formed by the polygonal metal sleeve 10.
