Abstract
The utility model discloses a copper-aluminum wiring terminal, which comprises a wiring end and a wiring pole end. The wiring end consists of a drum with an opening at one end, and the wiring pole end comprises a platy structure provided with a wiring hole. The copper-aluminum wiring terminal is characterized in that the wiring pole end consists of copper material layers and an aluminum material layer, the copper material layers are tightly combined on two side surfaces of the platy structure, the aluminum material layer is positioned in the middle of the platy structure, and the wiring end is made of aluminum materials and is integrally formed with the aluminum material layer in the middle of the wiring pole end. The copper-aluminum wiring terminal has the advantages of better safety performance, high power transmission efficiency, low cost and the like.
Description
Technical field
The utility model relates to a kind of copper al wiring terminal, especially a kind of copper al wiring terminal that is applicable to that cable is connected with the electric equipment transition in the power distribution equipment.
Background technology
When inserting large electric equipment, various cables all need to adopt binding post to connect, existing modal a kind of binding post, its structure is for comprising terminals and a wiring styletable, described terminals are the cylindrical body of one one end opening, the wiring styletable is a laminated structure with connecting hole, cable was connected in the opening of terminals cylindrical body when it connected, and the wiring styletable adopts and is bolted on the binding post.Because the transmission of electricity cable generally adopts aluminum, and electric equipment and binding post generally adopt copper product.Adopt aluminum so binding post also is terminals, the wiring styletable adopts copper product and carries out combination at the terminal middle part.Combination for two kinds of materials in the binding post, adopt generally in the prior art that explosive welding (EW) is tight, friction welding (FW) is tight or mode high temperature vacuum brazing makes it in conjunction with closely, after closely, can avoid preferably reducing power transmission efficiency like this, guarantee the normal conveying of electric current because of air enters connection slit generation electrochemical reaction.
But the copper al wiring terminal of this existing structure, after connection is good, because cable weight is bigger, can pair of wire connection terminals apply bigger shear stress, because being different material connections, copper al wiring terminal two ends obtain, though two ends are comparatively tight in conjunction with getting, under bigger shear stress, still produce slit even fracture easily from the junction, and then cause accidents such as cable is blown out, outage.According to statistics, have 60% all to be in the existing power gold utensil repairing accident because the problem of above-mentioned copper al wiring terminal causes.It is bigger to cause damage.
The utility model content
At above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is how to design the better copper al wiring of a kind of fail safe terminal.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of copper al wiring terminal, comprise terminals and a wiring styletable, described terminals comprise the cylindrical body of one one end opening, the wiring styletable comprises a laminated structure with connecting hole, it is characterized in that, described wiring styletable is by combining closely in the copper material layer of laminated structure both side surface and the aluminium material bed of material in the middle of being positioned at constitutes, described terminals constitute by aluminum material and be positioned at the wiring styletable in the middle of the aluminium material bed of material be formed in one and obtain.Wherein said combining closely is meant not have in conjunction with the slit, and air can not enter and cause in it producing electrochemical reaction and influence power transmission efficiency, specifically can adopt the combination described in the background technology or other combinations.
Copper al wiring terminal of the present utility model has the following advantages: 1, fail safe is better, in this copper al wiring terminal, terminals and wiring styletable intermediate layer all are to adopt that aluminum material is one-body molded to be obtained, aluminum material and position, copper material junction have been changed, so after installing in the use, the shear stress that is delivered on the binding post because of the cable deadweight can not cause binding post to produce slit or fracture from the middle part, and fail safe is better.2, power transmission efficiency height, binding post of the present utility model, terminals are aluminum material, two surfaces that the wiring styletable is connected with binding post are copper material, and combine closely between two kinds of materials, so can not produce the connection slit, cause air to enter and produce electrochemical reaction and influence power transmission efficiency, have the high characteristics of power transmission efficiency.3, save cost, adopt the utility model structure, at the wiring styletable two superficial layers only being arranged is copper products, all the other are aluminum, so compare the consumption of copper product reduces greatly with the described existing structure of background technology, because the copper product price is far above aluminum, so the utility model structure also has advantage with low cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments structure of the present utility model is described in further detail.
When the utility model is implemented, as shown in Figure 1, a kind of copper al wiring terminal, comprise terminals 1 and a wiring styletable, described terminals 1 comprise the cylindrical body of one one end opening, the wiring styletable comprises a laminated structure with connecting hole 4, wherein, described wiring styletable is by combining closely in the copper material layer 3 of laminated structure both side surface and the aluminium material bed of material 2 in the middle of being positioned at constitutes, described terminals 1 constitute by aluminum material and be positioned at the wiring styletable in the middle of the aluminium material bed of material be formed in one and obtain.
