However, the average temperature of the steel core heat-resistant aluminum alloy stranded wire is about 150 ℃ when the steel core heat-resistant aluminum alloy stranded wire runs for a long time, the short-time temperature can reach 220 ℃, the strength of the common tension-resistant wire clamp is weakened after being heated, the grip strength cannot meet the requirements of the line, the power transmission requirements cannot be met, the safety of the line cannot be guaranteed, and the like. Therefore, it is necessary to provide a strain clamp for a stranded wire.
Disclosure of Invention
Lead to the problem that the grip reduces, crimping intensity is low because of high temperature to current strain clamp, the utility model provides a can bear high temperature and rational in infrastructure, crimping intensity safe and reliable's strain clamp for the heat-resisting aluminum alloy stranded conductor of steel core.
In order to solve the above problems, the utility model adopts the following technical proposal.
The utility model provides a strain clamp for stranded conductor, includes the fastener main part to and the steel anchor of cartridge in the fastener main part, the fastener main part is close to this side welding of steel anchor and is fixed with the drainage board, is 110 degrees contained angles between this drainage board and the fastener main part, be fixed with the drainage fastener on the drainage board, wherein this fastener main part and drainage fastener adopt aluminum alloy material.
Preferably, one side of the steel anchor is provided with an annular slotted hole, the other side of the steel anchor is provided with a hollow semi-through crimping hole, and the steel anchor is made of carbon steel.
Preferably, the drainage plate and the drainage clamp are assembled and fixed through a hexagon head bolt.
Advantageous effects
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses adopt the preparation of heat-resisting aluminum alloy material between well fastener main part and the drainage fastener, make these two main parts have higher heat resistance, the fastener main part is with forming 100 degrees contained angles each other between the drainage plate, guarantee that the wire jumper has better extension radian, reduce the tension that the wire jumper receives, the annular slotted hole and the tower body of steel anchor are connected, other end crimping stranded conductor steel core makes its taut fastening, make the circuit have good mutually perpendicular performance, the annular slotted hole of steel anchor produces the meshing effect after the crimping, increase the fixed effect of fastener main part to the heat-resisting aluminum alloy stranded conductor of steel core.
