Description
Technical field
The utility model is related to electric armour clamp product, more particularly to a kind of copper aluminium Special-shaped parrel-slot cable clamp.
Background technology
In the connection of electrical lead, Jing will often be used and for the mode that aluminum steel is transitioned into copper cash be realized wire conduct power
Ability, therefore, copper aluminium Special-shaped parrel-slot cable clamp arises at the historic moment, and copper aluminium Special-shaped parrel-slot cable clamp of the prior art has following lacking
Fall into：
1st, wire clamp conductive capability is poor；
2nd, copper aluminium junction resistance is big, and aluminium copper-clad situation is there is also sometimes, and bound edge burr is easily caused electric spark generation；
3rd, size small end conductor clamping power occurs when wire clamp both sides conductor size is inconsistent not enough, wire loosens even
Slip comes off；
It is highly desirable to design a kind of copper aluminium Special-shaped parrel-slot cable clamp and overcomes drawbacks described above.
Utility model content
For defect present in above-mentioned background technology, the utility model devises a kind of copper aluminium Special-shaped parrel-slot cable clamp, should
Product structure design rationally, can be very good to overcome associated disadvantages.
To achieve these goals, the technical scheme that the utility model is provided is as follows：
Copper aluminium Special-shaped parrel-slot cable clamp, including base plate and gland, base plate is connected composition, base plate with aluminium block with gland by copper billet
Corresponding with gland both sides to be designed with wire casing, wire casing is crown face groove, in order to realize being set on more preferable conductive capability wire casing end face
In respect of thread groove；Press strip is designed with gland, press strip upper design has bolt slot, on base plate, gland and press strip spiral shell is designed with
Keyhole, screw bolt passes press strip, gland and base plate are connected with nut, gland bolt hole size in the longitudinal direction with bolt one
Cause, in the lateral direction more than bolt, joint face is arc surface between the press strip and gland, is designed with gland trapezoidal recessed
Groove, trapezoidal groove offsets with base plate wire casing；Open trough is designed with base plate, the open trough design is in copper billet and aluminium block connection position
Put.
The bolt hole designed on gland can be rectangular opening.
Preferably, the bolt hole for designing on gland is mounting hole.
Copper billet is connected with aluminium block connecting end surface using friction-welding technique, and the technique can be very good to overcome connecting end surface
Surface defect, realizes preferably connection, reduces junction resistance.
In view of copper aluminium material cost, it is preferred that aluminium block left and right directions size is more than copper billet, open trough is designed on aluminium block,
Open groove edge offsets with copper billet, on the premise of properties of product are not affected, reduces product material cost.
The open trough can be V-groove, dovetail groove or U-type groove.
For more preferable connection effect, bolts and nuts connection end is arranged with successively pad, packing ring.
Bolt is made up of nuts, connecting rod, convenience when using for product, on press strip design bolt slot size with
Nuts size matches, and nuts is fixed in bolt slot after turning to prepare.
The beneficial effects of the utility model be by adopting said structure design, on wire casing end face thread groove being designed with,
Tightened with nut by bolt, increase wire and wire casing effective contact area, increase wire clamp conductive capability；Copper aluminium junction passes through
Friction-welding technique, improves contact end face and reduces contact jaw surface resistance, link position design open trough, it is to avoid copper aluminium link position
Aluminium copper-clad situation when having, is not in that bound edge burr causes electric spark to produce；Mounting hole on gland coordinates with bolt, plus
Ceiling molding gland is arc surface contact, and gland trapezoidal groove coordinates with base plate arc groove, and wire clamp both sides conductor size is inconsistent
When be also not in that the inadequate wire of size small end conductor clamping power loosens situation about coming off of even sliding；Therefore it is not difficult to find out,
The copper aluminium Special-shaped parrel-slot cable clamp that the utility model is provided can be very good to overcome the defect that Related product is present in prior art.

Specific embodiment
As shown in Figure 1, 2, copper aluminium Special-shaped parrel-slot cable clamp, including base plate 1 and gland 2, base plate 1 and gland 2 by copper billet with
Aluminium block connection composition, base plate 1 is corresponding with the both sides of gland 2 to be designed with wire casing 11, and wire casing 11 is crown face groove, is designed on gland 2
There is press strip 3, the upper end of press strip 3 is designed with bolt slot, bolt hole, the bolt hole chi of gland 2 are designed with base plate 1, gland 2 and press strip 3
Very little consistent with bolt 4 in the longitudinal direction, in the lateral direction more than bolt 4, bolt 4 sequentially passes through press strip 3, gland 2 and bottom
Plate 1 is connected with nut 7, and bolt 4 is arranged with successively pad 5, packing ring 6 with the connection end of nut 7, connects between the press strip 3 and gland 2
