Abstract
The utility model belongs to the technical field of electrolytic aluminium and nonferrous metals, and in particular relates to a copper aluminum telescopic joint for the connecting of an electrolytic cell cathode steel bar and an aluminium busbar. The copper aluminum telescopic joint comprises a connecting soft belt composed of a plurality layers of purple copper foil pieces, the purple copper foil pieces are welded at the pressure welding end of one end of the connecting soft belt and aluminium block of the other end of the connecting soft belt respectively through high temperature and molecular diffusion. The copper aluminum telescopic joint is characterized in that a silver layer is plated on the pressure welding surface of the connecting soft belt. According to the copper aluminum telescopic joint provided by the utility model, the defect that the rigid connecting piece of the electrolytic cell cathode steel bar and the aluminium busbar can not stretch and move is solved, the problem that the rigid connecting piece can not be welded in large magnetic field is solved, and the pressure drop between the electrolytic cell cathode steel bar and the aluminium busbar is controlled within 5 MV. Through the adoption of the copper aluminum telescopic joint, the silver plating of the pressure welding end surface enables the resistance between the pressure welding end and the cathode steel bar to be decreased and the electric conductivity to be increased, work fever is decreased, and contact surface oxidation phenomenon due to long-term contact of the pressure welding surface and the cathode steel bar is solved as well.
Description
Technical field
The utility model belongs to electrolytic aluminum and non-ferrous metal technical field, especially relates to a kind of copper aluminium telescopic joint for being connected between aluminum cell cathode steel bar and the cathode aluminium busbar.
Background technology
The web member of electrolytic aluminum and non-ferrous metal industry generally all adopts hard the connection, and its shortcoming is need cut when maintenance, can't play mobile and flexible effect, can't solve the error that causes because of installation.And reaching 240KA when above when electrolytic cell currents, powerful magnetic field can't be carried out all welding processs, can cause serious loss to production and have a power failure.The patent No. is the coupling device that the Chinese utility model patent of CN200620091342X discloses a kind of aluminum cell cathode steel bar and cathode aluminium busbar, be provided with the connecting soft band that red copper foil is made therebetween, connecting soft band one end is connected with pressure connection terminal, the other end of connecting soft band is by two copper bars and aluminium block welding, pressure connection terminal is connected with aluminum cell cathode steel bar, aluminium block end and cathode aluminium busbar welding.Although this utility model patent has used the mode of connection of connecting soft band, avoided the shortcoming of rigid connection, the pressure connection terminal surface contact surface oxidative phenomena occurs with aluminum cell cathode steel bar long meeting duration of contact, and electric conductivity is reduced, increase work heating.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate and the copper aluminium telescopic joint of telescopic action arranged.
The purpose of this utility model realizes by following technical proposals:
Copper aluminium telescopic joint of the present utility model, comprise the connecting soft band that multilayer red copper paillon foil consists of, be welded on respectively the pressure connection terminal of this connecting soft band one end and the aluminium block of the described connecting soft band the other end through the high temperature molecular diffusion, it is characterized in that on the pressure connection terminal surface of described connecting soft band silver coated.
The pressure connection terminal surface-welding of described connecting soft band has copper coin.
Advantage of the present utility model:
Copper aluminium telescopic joint of the present utility model has not only solved the shortcoming that the rigid connection spare of aluminum cell cathode steel bar and cathode aluminium busbar can't stretch and move, also solved the problem that rigid connection spare can't weld greatly because of magnetic field, guaranteed that pressure drop between aluminum cell cathode steel bar and the cathode aluminium busbar is in 5MV.The silver-plated resistance decreasing that makes the surface in contact of pressure connection terminal and aluminum cell cathode steel bar on copper aluminium telescopic joint pressure connection terminal of the present utility model surface, electric conductivity increases, having reduced works generates heat, and has solved because pressure connection terminal is surperficial the contact surface oxidative phenomena to occur with aluminum cell cathode steel bar long meeting duration of contact.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of copper aluminium telescopic joint of the present utility model, comprise the connecting soft band 2 that multilayer red copper paillon foil consists of, be welded on respectively the pressure connection terminal 1 of these connecting soft band 2 one ends and the aluminium block 3 of described connecting soft band 2 the other ends through the high temperature molecular diffusion, it is characterized in that pressure connection terminal 1 surface silver coated 5 at described connecting soft band 2.Pressure connection terminal 1 surface-welding of described connecting soft band 2 has copper coin 4.
