Abstract
The utility model relates to a contact network power supply part used for an electrical rapid transit railway. A wire clamping device includes a C-shaped wire clamping seat, wherein a middle clamping plate is arranged on the C-shaped wire clamping seat, C-shaped space surrounded by the C-shaped wire clamping seat is divided into two plug wire holes by the middle clamping plate. The wire clamping device has the advantages of simple structure, convenience for use, and reduction of cost.
Description
Technical field
The utility model relates to a kind of electrified high-speed railway contact net power supply part.
Background technique
Existing to electrification railway lead fix and the general structure of device of installing all reasonable inadequately, service time, long can causing damage to lead can not well be fixed lead, easy becoming flexible.
Summary of the invention
The purpose of this utility model is fully to substitute import, more superior prior art on usability and provide a kind of simple in structure, wire-clamping device easy to use.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of wire-clamping device, comprise c-shaped clamp deck 1, and on the clamp deck of C shape, be provided with the middle part clamping plate, the C shape separated by spaces that the middle part clamping plate surround C clamp ply-yarn drill seat is two plug wire holes.
Further, the interior seamed edge of the clamp deck of described C shape is circular-arc.This circular-arc making when press-fiting copper stranded conductor contacts well, and is difficult for injury copper stranded conductor surface.
Further, described middle part clamping plate are strip, and two long limits of long strip middle part clamping plate are circular-arc, and at least one minor face and the clamp deck of long strip middle part clamping plate flexibly connect.The middle part clamping plate guarantee that two copper stranded conductors closely contact, and enough slippage loads are arranged.
Further, on described C clamp ply-yarn drill seat, the outer seamed edge of close C shape opening is provided with and press-fits breach, makes things convenient for the assembling of copper stranded conductor.The breach size directly influences the degree of tightness that press-fits copper stranded conductor, and whether enough slippage loads are arranged.
Further, described C clamp ply-yarn drill seat is to be made by oxygen free copper.By ingot casting, extruding, stretching, sawing, machine add, operation such as heat treatment, pickling, check finishes.
The beneficial effects of the utility model are: simple in structure, easy to use, cost is low, and is stressed reasonable in use, is difficult for loosening, practical more.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model after press-fiting.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Embodiment 1: shown in Figure 2 as Fig. 1, a kind of wire-clamping device comprises c-shaped clamp deck 1, is provided with middle part clamping plate 2 on the clamp deck 1 of C shape, and the C shape separated by spaces that middle part clamping plate 2 surround C clamp ply-yarn drill seat 1 is first plug wire hole 11 and second plug wire hole 12.The interior seamed edge of the clamp deck 1 of described C shape is circular-arc.Described middle part clamping plate 2 are strip, and two long limits of long strip middle part clamping plate are circular-arc, minor face of long strip middle part clamping plate and the flexible connection of clamp deck.On described C clamp ply-yarn drill seat 1, the outer seamed edge of close C shape opening is provided with and press-fits breach 5, conveniently press-fits.Described C clamp ply-yarn drill seat is to be made by oxygen free copper.At the wire-clamping device described in Fig. 2 an annealed copper strand wire 3 and hard drawn copper strand wire 4 dresses are pressed.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
