Abstract
The utility model discloses a kind of cable, overhead wire switching wire clamp, include a U-shaped strip shape body, the inner bottom surface of U-shaped strip shape body is provided with two spaced arc grooves extended along strip shape body length direction, also include the portable plate of more than two pieces, the quantity of the threaded connector on bottom the quantity of portable plate and strip shape body is suitable, also include a rebound, described rebound is arranged on the skin of portable plate, described rebound is the structure of two-layer, and outer layer covers internal layer.The utility model changes due to the various situations that flexible cable and overhead transmission line cause without suitable switching gold utensil in prior art, because strip shape body and portable plate adopt albronze material to make, have conduct electricity very well, feature that mechanical strength is high.Simultaneously owing to adding rebound, on electric conductivity, therefore realize the transition gradually of copper, aluminium material resistivity, ensure the stable operation after Nodes conduction.
Description
Technical field
The utility model relates to a kind of wire clamp, particularly a kind of cable, overhead wire switching wire clamp.
Background technology
At present, the low pressure flexible cable terminal of mobile box transformer vehicle, intelligent substation, dislocation generation car all configures compression-type copper arrangement terminal, owing to not having special fastening means, method conventional is at present that directly flexible cable is wound into aerial cable then uses immobilization with adhesive tape.Because flexible cable own wt is heavier, this connected mode, is easy to get loose, the various accident such as cause connecting portion to rupture, to sparkle.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of cable for connecting flexible cable and overhead transmission line is provided, overhead wire transfers wire clamp.
A kind of cable, overhead wire switching wire clamp, include a U-shaped strip shape body, the inner bottom surface of U-shaped strip shape body is provided with two spaced arc grooves extended along strip shape body length direction, interval between two arc grooves bottom strip shape body is provided with plural through hole, through hole is provided with threaded connector, also include the portable plate of more than two pieces, the quantity of the threaded connector on bottom the quantity of portable plate and strip shape body is suitable, each portable plate is provided with a through hole passed for threaded connector, the side of portable plate towards the end in strip shape body is alongst also provided with two arc grooves corresponding with the arc groove at the end in strip shape body, also include a rebound, described rebound is arranged on the skin of portable plate, the length and width of described rebound are suitable with length with the groove width of strip shape body U-type groove, described rebound is the structure of two-layer, outer layer covers internal layer, wherein rebound is internal layer is the outer rebound for tin coating of pure copper layer, portable plate and strip shape body are portable plate and the strip shape body of fine aluminium, threaded connector is the threaded connector of almag.
Cable of the present utility model, overhead wire switching wire clamp, have employed strip shape body, portable plate and rebound, connect with threaded connector between three, during use, the groove alignment aerial cable at the end in strip shape body is mounted thereto, and the copper arrangement terminal of low pressure flexible cable is installed on the threaded connector outside rebound, then fastening nut realizes the connection of flexible cable and overhead transmission line cable, this connected mode, because copper arrangement terminal contacts with rebound with nut or pad, due to copper, there is larger difference in the resistivity of aluminium material, the contact-making surface contact resistance value of compression-type copper arrangement terminal and portable plate is very large, long-time use will cause contact-making surface seriously to generate heat, node is caused to melt, accidents caused.Therefore, between compression-type copper arrangement terminal and portable plate, add zinc-plated rebound, be fixed by extended type threaded connector, form cable and overhead wire and to transfer wire clamp.Electric conductivity realizes the transition gradually of copper, aluminium material resistivity, ensures the stable operation after Nodes conduction; Mechanical performance meets and bears the gravity of flexible cable, avoid and junction occurs to get loose the accident even ruptured.The feature that the conductive energy of this wire holder is good, mechanical strength is high.
The skin of portable plate refers on rebound has that relative side of arc groove.
The tapped through hole at portable plate place is arranged at the centre of portable plate.
In sum, the utility model following advantage compared to existing technology:
Cable of the present utility model, overhead wire switching wire clamp, change in prior art due to various situations that flexible cable and overhead transmission line cause without suitable switching gold utensil, because strip shape body and portable plate adopt albronze material to make, have conduct electricity very well, feature that mechanical strength is high.Simultaneously owing to adding rebound, on electric conductivity, therefore realize the transition gradually of copper, aluminium material resistivity, ensure the stable operation after Nodes conduction.
