Description
Technical field
The utility model relates to technical field of cable connection, particularly a kind of cable connection terminal.
Background technology
Aluminium alloy power cable be with AA8030 series aluminium alloy material for conductor, adopt the new material power cable of the advanced technology innovation and creation such as special impacted process and annealing in process.Alloy power cable compensate for the deficiency of fine aluminium cable in the past, although do not improve the electric conductivity of cable, but bending property, creep-resistant property and decay resistance etc. improve greatly, can ensure cable long term overloading and overheated time keep continuous stable performance, adopt AA8000 series alloys conductor, greatly can improve conductance, the heat-resisting quantity of aluminium alloy cable, solve the problems such as the electrochemical corrosion of fine aluminium conductor, creep simultaneously.The conductance of aluminium alloy is 61.8% of the most frequently used reference material copper IACS, and ampacity is 79% of copper, is better than fine aluminium standard.But under the same volume, the actual weight of aluminium alloy is approximately 1/3rd of copper.Therefore, during identical ampacity, the weight of aluminium alloy cable is approximately the half of copper cable.Adopt aluminium alloy cable to replace copper cable, can cable weight be alleviated, reduce installation cost, reduce the wearing and tearing of equipment and cable, make installment work lighter.
Along with popularizing of aluminium alloy power cable, the connectivity problem of aluminium alloy power cable and circuit breaker highlights day by day.Cable all needs to be connected with circuit breaker by splicing ear, at present splicing ear be generally copper-aluminium terminal, its primarily of aluminum content 99.6% fine aluminium and copper content 99.9% T2 copper become.There is many deficiencies in this splicing ear: the electric current on one, cable passes through aluminium alloy cable successively---aluminum material---copper material, have passed through the medium of three different electric properties, result in the sectional area that on splicing ear, some block supply stream flows through not enough, cause splicing ear to generate heat, serious meeting causes circuit breaker to damage and accident; They are two years old, because aluminium alloy cable, copper-aluminium terminal are by different manufacturer production, the manufacturer of splicing ear is in order to ensure that its product can be applicable to each cable producer most possibly, generally all take large scale, endoporus goes on poor mode, make like this aluminium alloy cable and copper-aluminium terminal Contact tight not, cause Joint failure.
Utility model content
The purpose of this utility model is that providing a kind of connects reliable and that electric property is good cable connection terminal.
For realizing above object, the technical solution adopted in the utility model is: a kind of cable connection terminal, comprise sleeve, the cable that aluminium alloy is made inserts from one end of sleeve, and the other end of sleeve is provided with connecting portion, and the suspension end of connecting portion forms copperhead, copperhead is provided with through hole for being connected with circuit breaker, described sleeve adopts the aluminum alloy materials identical with cable to make, and connecting portion is made up of copper material, and the ampacity of connecting portion is more than or equal to the ampacity of cable.
Compared with prior art, there is following technique effect in the utility model: cable connection terminal adopts aluminum alloy material and copper material, avoid the fever phenomenon caused through various kinds of media matter, simultaneously, the size of cable connection terminal can be suitable with cable, make crimp after cable and splicing ear firm, tight, reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
Embodiment
Below in conjunction with Fig. 1 to Fig. 3, the utility model is described in further detail.
Consult Fig. 1-Fig. 3, a kind of cable connection terminal, comprise sleeve 10, the cable that aluminium alloy is made inserts from one end of sleeve 10, the other end of sleeve 10 is provided with connecting portion 20, and the suspension end of connecting portion 20 forms copperhead 21, copperhead 21 is provided with through hole 211 for being connected with circuit breaker, described sleeve 10 adopts the aluminum alloy materials identical with cable to make, and connecting portion 20 is made up of copper material.Sleeve 10 adopts the aluminum alloy materials same with cable to make, and such electric current is from cable to circuit breaker, and only through the medium that aluminium alloy, copper two kinds are different, the smoothness of guarantee current flowing, avoids the generation of local pyrexia phenomenon.Meanwhile, the splicing ear that aluminium alloy becomes with copper, can be produced by the producer producing aluminium alloy cable, the size of the sleeve 10 of such splicing ear just well can mate cable, avoids size difference excessive and the unreliable phenomenon of connection that is that cause.The ampacity of connecting portion 20 is more than or equal to the ampacity of cable, the maximum current that each cross section, position of splicing ear can be carried by cable smoothly can be ensured like this and do not generate heat, in theory, the combined closure system of connecting portion 20 just can satisfy the demands when equaling the combined closure system of cable, but in the design of reality, the ampacity of connecting portion 20 should slightly larger than the ampacity of cable.
Preferably, one end that described sleeve 10 is connected with connecting portion 20 is closed and is outwards postponed and is provided with conical section 11 and reduced diameter section 12; Described connecting portion 20 is in flap-like, the outside in the first plate face 22 vertical with sleeve 10 axle core is connected with reduced diameter section 12 by cylindrical section 24, outside mentioned here and the left side shown in Fig. 2, the copperhead 21 described in the suspension end in the second plate face 23 parallel with sleeve 10 axle core is formed.Connecting portion 20 is arranged to flap-like, and when preventing splicing ear to be connected with circuit breaker, sleeve 10 and miscellaneous part interfere.
In order to ensure that the sleeve 10 that aluminum alloy materials is made can reliably be connected with the connecting portion 20 that copper material is made, in the present embodiment preferably, cylindrical section 24 coincide with reduced diameter section 12 outside dimension and both are fixedly connected with by the mode of friction welding.In order to adopt the technique of friction welding to connect, cylindrical section 24 and reduced diameter section 12 are set, and both diameters coincide here, when connecting, first both docked, then High Rotation Speed, makes sleeve 10 and connecting portion 20 be fixed together reliably by fricative heat.
More preferably, the first described plate face 22 top edge is semicircular arc, and this arc-shaped clearly can illustrate from Fig. 3, and the center of circle of this semi arch is positioned on the axle core of reduced diameter section 12.Do like this, the materials of connecting portion 20 can be reduced, reduce volume and weight.
Further, the periphery of described copperhead 21 is provided with the axle core that two trimmings, 212, two trimmings 212 are all parallel to sleeve 10.Described copperhead 21 entirety is in circular, and trimming 212 cuts part formation for annulus periphery, and the side plate body thickness that the second plate face 23 arranges through hole 211 is greater than the plate body thickness of other positions.The copperhead that circular copperhead 21 often there will be splicing ear inserts to enter the phenomenon in circuit breaker interface, like this after setting, can ensure that the copperhead 21 of splicing ear is reliably connected with circuit breaker, and need not cut copperhead 21.
