(3) Due to environmental reasons, particularly in coastal acid and alkaline environments, the corrosion of the copper-aluminum transition connecting terminal is serious, and the electric conduction and the service life are influenced.

Disclosure of Invention

The utility model relates to a copper and aluminum transition binding post goes up copper and aluminum combination position and easily appears crackle, phenomenon of rupture when solving current copper stranded conductor and aluminum stranded conductor and being connected, leads to having the potential safety hazard and change the problem of maintaining inconvenience, and then provides a copper and aluminum transition binding post uses protection fastener.

The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be:

the utility model provides a copper aluminium transition binding post is with protection fastener, it includes the fastener body and parallel respectively sets firmly first clamp plate and the second clamp plate in fastener body both sides, wherein the wiring board correspondence on the copper aluminium transition binding post is inserted and is established between first clamp plate and fastener body, the wiring board correspondence on the copper aluminium transition binding post is inserted and is established between second clamp plate and fastener body, the positioning bolt rigid coupling is passed through with the middle part of fastener body to two wiring boards, copper product board and the aluminum product board butt joint department on the copper aluminium transition binding post is located between first clamp plate and the fastener body.

Furthermore, the first pressing plate is positioned between the positioning bolt and the wiring tube on the copper-aluminum transition wiring terminal, and the second pressing plate is positioned between the positioning bolt and the wiring tube on the other copper-aluminum transition wiring terminal.

Furthermore, the first pressing plate is fixedly connected with the wire clamp body through two first bolts, the wiring board on the copper-aluminum transition wiring terminal is located between the two first bolts, the second pressing plate is fixedly connected with the wire clamp body through two second bolts, and the wiring board on the copper wiring terminal is located between the two second bolts.

Furthermore, the wire clamp body, the first pressing plate, the second pressing plate and the positioning bolt are all plated with tin layers.

Compared with the prior art, the utility model has the following effect:

through this application to current copper aluminium transition binding post protect, through two clamp plates and a positioning bolt, stress point when changing two original binding post and connecting has effectually avoided because the dead weight of wind pendulum and cable wire causes the atress of two binding post junctions and copper product board and aluminum product board butt joint department, prevents to take place copper aluminium transition binding post because the atress takes place the cracked accident even of fracture.

Detailed Description

The first embodiment is as follows: the embodiment is described with reference to fig. 1 to 4, a copper-aluminum transition connecting terminal protection wire clamp, which comprises a wire clamp body 1, a first pressing plate 2 and a second pressing plate 3 which are respectively and fixedly arranged on two sides of the wire clamp body 1 in parallel, wherein a wiring board 102 on the copper-aluminum transition connecting terminal 100 is correspondingly inserted between the first pressing plate 2 and the wire clamp body 1, a wiring board 102 on a copper connecting terminal 103 is correspondingly inserted between the second pressing plate 3 and the wire clamp body 1, the two wiring boards 102 are fixedly connected with the middle part of the wire clamp body 1 through positioning bolts 4, and the butt joint of a copper plate 1021 and an aluminum plate 1022 on the copper-aluminum transition connecting terminal is positioned between the first pressing plate 2 and the wire clamp body 1.

Protect current copper aluminium transition binding post 100 through this application, through two clamp plates and a positioning bolt 4, stress point when changing two original binding post and connecting, the effectual dead weight of having avoided because wind pendulum and cable wire causes two binding post junctions and the atress of copper product board 1021 and aluminum product board 1022 butt joint department, copper binding post's intensity has been increased simultaneously, prevent to take place copper aluminium transition binding post 100 because the cracked accident even takes place for the atress.
