Abstract

The utility model discloses a novel copper-aluminium transition connector lug comprising a first wiring board and a second wiring board, and the first wiring board is fixedly connected with the second wiring board; and the first wiring board comprises a first wiring base plate and a connecting rod, the first wiring base plate and the connecting rod are arranged in one body, and screw nut holes are arranged on the first wiring base plate. The novel copper-aluminium transition connector lug is simple in structure and easy in operation, the connector lug can bear a certain pressure stress and can still keep normal temperature and mechanical strength after a plurality of cold-thermo cyclings, electric appliance equipment is more stable, safe operation is realized, and power supply reliability is greatly improved.

Description

A kind of novel copper-aluminium transition connector lug
Technical field
The utility model relates to a kind of novel copper-aluminium transition connector lug.
Background technology
Along with society improves constantly the demand of power consumption and the requirement of electricity consumption reliability, make being on the increase of Utilities Electric Co.'s line construction, track remodelling and overhaul of the equipments task in recent years.These line construction transformation tasks inevitably need to use a large amount of copper-aluminium transition connector lugs.Old-fashioned copper-aluminium transition connector lug is owing to just simply copper sheet and aluminium flake part directly being docked welding, although manufacture craft is simple, but, copper al wiring head too small due to bonding area bears compression to a certain degree in actual use, copper al wiring head is in operation after cold cycling repeatedly (energising and outage), can make generation gap, solder side place and affect contact, also increased contact resistance, the increase of contact resistance will cause the temperature rising at copper al wiring head solder side place.Copper al wiring head solder side place at high temperature corrosion oxidation will aggravate, and produces vicious circle, and quality of connection is further worsened, the accident such as cause that at last the solder side excess Temperature even can smolder, blow.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of novel copper-aluminium transition connector lug, it is simple in structure, easy to operate, can bear certain compression and through repeatedly still keeping normal temperature and mechanical strength after cold cycling, make electric equipment more steady, safe operation has improved power supply reliability greatly.
The utility model is the purpose that reaches above-mentioned, and the utility model adopts following technical scheme:
A kind of novel copper-aluminium transition connector lug comprises the first terminal block and the second terminal block, and described the first terminal block and the second terminal block are connected; Described the first terminal block comprises the first patch bay and connecting rod, and the first patch bay and connecting rod integrated device form, and offers nut bore on wherein said the first patch bay.
Be provided with the first miniature sawtooth on described the first patch bay.
Described the second terminal block comprises the second wiring baffle plate and the second patch bay, and the second wiring baffle plate and the second patch bay integrated device form, and offers respectively the second miniature sawtooth on wherein said the second wiring baffle plate and the second patch bay.
Offer two nut bore on described the first patch bay.
The beneficial effects of the utility model are: the utility model provides a kind of novel copper-aluminium transition connector lug, it is simple in structure, easy to operate, can bear certain compression and after cold cycling repeatedly, still can keep normal temperature and mechanical strength, make electric equipment more steady, safe operation has improved power supply reliability greatly.

Embodiment
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of novel copper-aluminium transition connector lug, comprises the first terminal block 1 and the second terminal block 2, and described the first terminal block 1 and the second terminal block 2 are connected; Described the first terminal block 1 comprises the first patch bay 9 and connecting rod 4, and the first patch bay 9 and connecting rod 4 is integrally manufactured forms, and offers nut bore 3 on wherein said the first patch bay 9.The setting of nut bore 3 is convenient to be fixed connection with the copper cash that is connected; Thereby the installation of connecting rod 4 is convenient to be fixed with the aluminum steel that is connected and is connected the transition connection that realizes copper al wiring head.2 nut bore 3 have increased conductive area greatly.
As shown in Figure 2, Figure 3, Figure 4, be provided with the first miniature sawtooth 5 on described the first patch bay 9.Described the second terminal block 2 comprises the second wiring baffle plate 7 and the second patch bay 8, and the second wiring baffle plate 7 and second patch bay 8 is integrally manufactured forms, and offers respectively the second miniature sawtooth 6 on wherein said the second wiring baffle plate 7 and the second patch bay 8.The first terminal block 1 and the second terminal block 2 are for being welded to connect.And the setting of the first miniature sawtooth 5 and the second miniature sawtooth 6 and dislocation welding have improved the welding effect of the first terminal block 1 and the second terminal block 2 greatly, thereby improve the conductive effect of copper al wiring head.
A kind of novel copper-aluminium transition connector lug of the present embodiment manufacturing, it is simple in structure, easy to operate, can bear certain compression and after cold cycling repeatedly, still can keep normal temperature and mechanical strength, make electric equipment more steady, safe operation has improved power supply reliability greatly.
