Description
Technical field
This utility model relates to transformer technology field, particularly to a kind of transformer copper aluminum wire clamp.
Background technology
At present, existing transformator needs to flow through the electric current that conductor is the biggest, if therefore existed when power transmission and conversion
When cable attachment point contact is insecure, electric leakage or electric spark easily occur, this type of potential safety hazard can bring bigger economic damage
Lose, thus in order to improve being reliably connected on transformator junction point, be usually and use transformer copper aluminum wire clamp, but general line
Folder simply plays the effect of preliminary fixing connection, can not effectively combine electrical conductor in cable and can produce when indirect current
Kelvin effect, i.e. electric current or electrons trend towards cable conduction metallic surface, and are not to be evenly distributed in cable conductor
Cross section on, the resistance of junction point thus can be caused to become big, increase loss.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide raising connectivity robustness and improves contact
The contact surface of point is to reduce the transformer copper aluminum wire clamp of power consumption.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of transformer copper aluminum steel
Folder, including aluminum wire clamp and with aluminum wire clamp one is connected copper cash folder, described copper cash press from both sides include the sleeve of sidewall opening, two points
Not being integrally connected to the connection sheet of opening both sides, two described connection sheets are in being respectively equipped with through hole on sleeve two ends, described
The first securing member it is equipped with on through hole；Described aluminum wire clamp includes " u "-shaped frame, is arranged at the telescopic joint of " u "-shaped frame both sides, described in stretch
Casing coupling is fixed by the second securing member.
By above-mentioned setting, the metallic conductor in cable is through in sleeve, and owing to sleeve has opening, and it is upper and lower to connect sheet
Opening can be reduced the when of being close to, such that it is able to change the internal diameter of sleeve, the table of the metallic conductor being now through in sleeve
Face will receive deformation, thus due to the effect of extruding, its surface can well contact with sleeve lining, such that it is able to effectively
Reduce Kelvin effect, and connect the application point of sheet fastening force on two ends of sleeve, such that it is able to the metallic conductor being
Fixing more firm, and the deformation formed would is that two ends stress, the middle deformation supplied, and this deformation is advantageously in metal
Conductive surface contacts with sleeve；On the other hand, aluminum wire clamp uses " u "-shaped structure, and is fixed by telescopic joint, thus
Improve connectivity robustness.
Can be preferably as concrete scheme of the present utility model: the interlude of described connection sheet caves inward.
By above-mentioned setting, in order to ensure effectively to reduce under identical structural strength cost, use the centre by connecting sheet
Section is designed as caving inward, and can save material cost and can effectively ensure that structural strength.
Can be preferably as concrete scheme of the present utility model: the junction between described sleeve and " u "-shaped frame is arc
Shape face.
By above-mentioned setting, in order to reduce the stress concentration phenomenon of junction, it is designed to arcwall face and there is the inclined of power
Draw effect, be possible to prevent fracture.
Can be preferably as concrete scheme of the present utility model: described first securing member and the second securing member are spiral shell
Bolt, nut.
By above-mentioned setting, bolt, nut structure cooperate, and can carry out upper and lower spacing, and connection sheet is entered
Row draws in or draws telescopic joint in, thus the most fixing.
Can be preferably as concrete scheme of the present utility model: the interlude of described telescopic joint is the arc outwards arched upward
Portion.
By above-mentioned setting, the interlude of telescopic joint outwards arches upward, and can play metallic conductor surface and guide deformation
Effect, improves the fastness connected.
In sum, this utility model has the advantages that by the design to structure, thus improves cable
The degree that is connected firmly, and effectively reduce the impact of Kelvin effect, enhance product performance, and improve service life.
Accompanying drawing explanation
Fig. 1 is the structural representation one of the present embodiment；
Fig. 2 is the structural representation two of the present embodiment.
In figure 1, aluminum wire clamp；11, sleeve；12, sheet is connected；13, through hole；14, opening；2, copper cash folder；21, " u "-shaped frame；
22, telescopic joint；3, arcwall face；4, bolt；5, nut；6, curved portions.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment: as it is shown in figure 1, a kind of transformer copper aluminum wire clamp, be connected including aluminum wire clamp 1 and with aluminum wire clamp 1 one
Copper cash folder 2, copper cash folder 2 material be copper metal material, the material of aluminum wire clamp 1 is aluminum metal material.Copper cash folder 2 includes sidewall
11, two connection sheets 12 being integrally connected to opening 14 both sides respectively of the sleeve of opening 14, two connect sheet 12 near sleeve
Being respectively equipped with through hole 13 on 11 two ends, through hole 13 is equipped with the first securing member, the first securing member is bolt 4 and joins with bolt 4
The nut 5 closed, as in figure 2 it is shown, bolt 4 is through through hole 13, and is fixed by nut 5.Aluminum wire clamp 1 includes " u "-shaped frame 21, arranges
In the telescopic joint 22 of " u "-shaped frame 21 both sides, telescopic joint 22 is fixed by the second securing member.The interlude connecting sheet 12 concaves
Fall into.Junction between sleeve 11 and " u "-shaped frame 21 is arcwall face 3.Second securing member is bolt 4, nut 5.Telescopic joint 22
Interlude is the curved portions 6 outwards arched upward.
Said structure is had to understand: during use, the mounting means of patch cord is mutually perpendicular to.First securing member can will be opened
Mouth 14 reduces, such that it is able to change the internal diameter of sleeve 11, the surface being now through the metallic conductor in sleeve 11 will receive shape
Become, thus due to the effect of extruding, its surface can well be with sleeve 11 contact internal walls, such that it is able to effectively reduce the skin effect that becomes
Should, and connect the application point of sheet 12 fastening force on two ends of sleeve 11, such that it is able to the metallic conductor being is fixing more
Add firmly, and the deformation formed would is that two ends stress, the middle deformation supplied, and this deformation is advantageously in metallic conductor table
Face contacts with sleeve 11；On the other hand, aluminum wire clamp 1 uses " u "-shaped structure, and is fixed by telescopic joint 22, thus
Improve connectivity robustness.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
