Utility model content
Technical problem to be solved in the utility model is to provide a kind of aluminium alloy core high conductivity aluminium stranded conductor strain clamp, the strain insulator mainly solving existing strain clamp inapplicable aluminium alloy core high conductivity aluminium stranded conductor is fixed, and easily aluminium alloy core is caused to the problem of damage or fracture during crimping.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of aluminium alloy core high conductivity aluminium stranded conductor strain clamp, this strain clamp comprises wire clip body, steel anchor, bolt, nut, drainage plate, conduction wire clamp, aluminium alloy bushing pipe and aluminium bushing pipe; The inner corresponding crimp segment of described wire clip body establishes aluminium bushing pipe, and be also provided with aluminium alloy bushing pipe in wire clip body and be connected with described steel anchor, the external stability drainage plate of wire clip body, described conduction wire clamp is fixed on described drainage plate by bolts and nuts.
Further, described wire clip body outside is aluminum pipe.
Further, described aluminium alloy bushing pipe material is 6063 aluminium alloys, and aluminium bushing pipe material is 1050A aluminium.
Further, described aluminium alloy bushing pipe and aluminium bushing pipe are hollow cylinder shape.
Further, make aluminium alloy core high conductivity aluminium stranded conductor insert wire clip body in aluminium alloy bushing pipe from one end of described aluminium bushing pipe, and contact with described steel anchor, by hydraulic method, aluminium alloy bushing pipe is crimped, thus steel anchor, aluminium alloy core and aluminium alloy bushing pipe are connected as one, afterwards the steel anchor after crimping is pushed in wire clip body, aluminium bushing pipe is pushed in wire clip body, by hydraulic method, wire clip body, aluminium bushing pipe and aluminium alloy core high conductivity aluminium stranded conductor is compressed.
The beneficial effects of the utility model:
Strain clamp of the present utility model takes the structure arranging aluminium alloy bushing pipe and aluminium bushing pipe in wire clip body, and aluminium alloy core clamps by the close and feature that the is material property matched with the intensity of steel anchor of close and aluminium alloy bushing pipe and aluminium alloy core the hardness of the hardness making full use of aluminium bushing pipe and outer high conductivity aluminium stranded conductor, and firmly crimp integral by the same wire clip body of bushing pipe set in crimp segment, aluminium stranded conductor, steel anchor, and external layer conductor and unlined aluminium alloy core are without any damage.Moreover, this utility model also have compact conformation reasonable, novel ingenious, temperature influence is little, shock-resistant fatigue resistance is strong, grip is evenly distributed, carry the power of hold avoids the advantages such as grip is loose by force, effectively.Meanwhile, this strain clamp reduces the outside dimension of strain insulator main body owing to employing two bushing pipes thus decreases the weight of strain clamp, reaches energy-saving and cost-reducing target.Have using value and vast potential for future development.
