Definitions

  • the proposal relates to electrified railway transport and is aimed at improving clamps for connecting wires of the contact network.
  • the presence of a protrusion on the upper part of the edge of the upper flange of the clamp allows using a press and an appropriate tooling to produce not only high-quality crimping of the clamp on the wire, but also to press the specified protrusion into the area between the lower part of the upper wire (for example, the bearing cable of the chain suspension) and the middle part clamp, which improves the quality of the electrical contact between the wire and clamp and, in turn, increases the current load capacity of the latter;
  • the cross section of the clamp must exceed the cross section of the connecting wires by 3 times or more;
  • its vertical supporting wall should have a thickness of 5 mm to 7 mm;
  • the bolt-free connecting clip contains a housing, in the upper part of which an open cavity is made to accommodate wires of unlimited length, a hole with a slot is made in the lower part of the housing to accommodate wires of limited length, while the cross-sectional area of the clamp exceeds not less than 3 times the cross-sectional area of the wires connected in the clamp, and in the lower part of the housing for placing wires of limited length in it, a section of length from 5 m to 10 mm at an angle of 15 ° to 30 ° to the horizontal and at the top edge of the upper clamping flange projection is formed.
  • the thickness of the supporting wall can be from 5 mm to 7 mm.
  • FIG. 1 shows a general view of the clamp.
  • FIG. 2 die and die for crimping.
  • FIG. 3 position of the clamp at the initial moment of crimping.
  • a bolt-free, extrudable clamp for wires contains a housing 1, in the upper part of which an open cavity 2 is made to accommodate wires of unlimited length, a hole 5 is made in the lower part of the housing with a slot 6 to accommodate a wire of limited length, while on the edge 3 of the upper part of the cavity, a protrusion 4 is made over the entire width of the clamp.
  • a section 9 is made with a length of 5 mm to 10 mm at an angle a from 15 ° to 30 ° to the horizontal
  • the height of the protrusion is from 2 to 6 mm, depending on the diameter of the connected wire, and the height of the slot corresponds to 0.3-0.4 diameter wire of limited length.
  • the size of the slot in the pressed clamp depends on the diameter of the wire of limited length and allows you to determine when the edges converge during the crimping process when the pressing is completed.
  • the mounting time of the proposed clamp is reduced to 12-19 s, which is several times longer than the mounting time of known clamps.
  • the proposed clamp is used in railway transport and is aimed at improving clamps for connecting wires of the contact network.

Abstract

L'invention se rapporte au domaine de l'électrification des transports ferroviaires, et a pour but de réaliser des pinces pour la connexion de conducteurs d'une ligne de contact. Le résultat technique consiste en une meilleure fiabilité de la pince, une meilleure commodité de fonctionnement et une diminution du temps de montage de la pince. Ce résultat technique est obtenu du fait que la pince de connexion sans boulon comprend un corps dans la partie supérieure duquel est formé une cavité ouverte afin d'y disposer un conducteur, tandis que la partie inférieure du corps comprend une ouverture avec une entaille afin d'y placer un conducteur de longueur limitée. La surface de la section transversale de la pince est au moins 3 fois supérieure à la surface de la section transversale des conducteurs à connecter dans la pince, et la partie inférieure du corps est tranchée selon un angle de 15° à 30° par rapport à l'horizontale sur une longueur de 5 mm à 10 mm.
