Description
Technical field
This utility model relates to being applied to low voltage electric network and industrial power distribution network cable connector copper-aluminum transition terminal, especially relates to a kind of High-performance aluminium alloy cable and connects terminal.
Background technology
Along with the high speed development of China's economic construction, the demand of electric power is continued to increase by every profession and trade, and the market space of wires and cables industry is huge.Common cable connecting terminals includes wiring nose and connecting tube, wiring nose one end is lamellar, the other end is cylindricality, connecting tube is hollow pipe, the cylindricality of wiring nose and connecting tube cast solid, but this structure exists following defect: one is that wiring nose is little with the contact area of connecting tube, it is susceptible to fracture；Two be wiring nose material be copper, connecting tube material is aluminum, pure cu conductor density is big and Domestic Resources is deficient, and the mechanical strength of aluminium conductor is on the low side, welding performance is poor, and contact resistance is big, in engineering project, popularization and application are restricted, more poor because of the heat stability of aluminium conductor, easily there is creep under the life-time service condition of high temperature, cause aluminium conductor power cable to frequently occur fault on engineer applied；Three is that connecting tube is for lv power cable abnormal shape cable conductor, such as sector, tile-type, semi-circular, owing to the two shape difference is the biggest, even if take shaping measure when joint, also the profile that conductor is accomplished rounding it is difficult to ensure that, cause space between conductor outside surfaces and connecting tube inwall uneven, run steadily in the long term to cable and bring hidden danger.
Utility model content
For the defect overcoming above-mentioned prior art to exist, this utility model provides a kind of High-performance aluminium alloy cable and connects terminal, this structure has additional copper-aluminium transition part, both the consumption of fine copper had been decreased, reduce cost, the mechanical strength of this part, heat stability can be improved again, the probability that under less high temperature, creep occurs, improves the overall performance of cable connecting terminals.
This utility model can be achieved through the following technical solutions: a kind of High-performance aluminium alloy cable connects terminal, including wiring nose and connecting tube, described connecting tube is hollow pipe, it is important to: also include the copper-aluminium transition part being arranged between wiring nose and connecting tube.
Described wiring nose longitudinal section is L-type, and its lateral part is fixed part, and its longitudinal component is connecting portion, and fixed part is arranged on connecting portion end face side and with connecting portion end face in obtuse angle.
Described fixed part is shaped as lamellar.
Described fixed part offers through hole.
Described connecting portion is shaped as cylindricality.
Described connecting tube axially offers plug wire hole.
Described plug wire hole is shaped as sector, tile-type or semicircle.
The opening of described connecting tube is provided with sealing lid.
Described connecting tube internal layer is provided with conductive paste layer.
The fixed part of described wiring nose and the angle of connecting portion end face are α, 90 °≤α≤135 °.
The beneficial effects of the utility model are:
In this structure, the fixed part of wiring nose is whole cylindrical cross section with the contact surface of copper-aluminium transition part, substantially increases the contact area of junction, it is to avoid rupture in junction；
The plug wire hole shape of connecting tube has multiple, including sector, tile-type or semicircle, is adaptable to special-shaped cable conductor, decreases the gap of conductor outside surfaces and connecting tube inwall, improves stability and safety that cable uses；
The opening of connecting tube is provided with sealing lid, can avoid the immersion of dust impurity during non-usage；
Connecting tube internal layer adds conductive paste layer, it is to avoid conductor is with to be connected termination contact bad, thus affects the stability that cable uses；
This structure has additional copper-aluminium transition part, has both decreased the consumption of fine copper, reduces processing cost, can improve again the mechanical strength of this part, heat stability, and the probability that under less high temperature, creep occurs improves the overall performance of cable connecting terminals；
The fixed part of this wiring nose and the angle of connecting portion end face are between 90 ° and 135 °, and angle is the least, are unfavorable for the fixing of wiring nose；Angle is too big, and junction contact area is little, is easily broken off.
