It is fixed in cable tray, realizes that lead-out wire covers being fixedly connected for steel earthing pole with copper.
Preferably, the ontology and clamp block are that copper covers bimetal copper-steel material copper and covers steel earthing pole.
Preferably, the clamp block includes pedestal and clamping part, the clamping part is fixedly connected including two or more
Pawl on pedestal, more than two pawls surround clamp hole, and the internal diameter in the clamp hole is less than the outer diameter of conducting wire to be held.
Clamping part is made of more than two pawls, is provided with gap between adjacent pawl, when clamping part protrudes into cable tray
When, due to the limitation of cable tray diameter, the spacing between adjacent pawl can reduce, so that the diameter in clamp hole subtracts
It is small, lead-out wire is clamped.
Preferably, being connected through a screw thread between the clamping part and cable tray.
Preferably, being interference fitted connection between the clamping part and cable tray.
Preferably, one end of the cable tray setting clamp block, internal diameter is gradually reduced from outside to inside.
It is bigger to the chucking power of lead-out wire when clamping part more protrudes into cable tray.
Preferably, the side that the pawl is located in clamp hole is provided with convex block.
The frictional force between clamping part and lead-out wire is improved, the two is prevented to be detached from.
Preferably, the cable tray is provided with the elasticity with cable tray coaxial arrangement far from one end of clamp block
Sleeve, one end of the resilient sleeve are fixed on the body.
The position that lead-out wire leaves cable tray is easy to be caused lead-out wire to be easily damaged by bending, so setting resilient sleeve
Cylinder gives one support force flexible of lead-out wire, the situation for preventing lead-out wire overflexing from fractureing.
Compared with prior art, the beneficial effects of the utility model are at least one of following:
By the way that clamp block and cable tray are arranged on the ontology that copper covers steel earthing pole, realize that lead-out wire and copper cover steel ground connection
The assembling of pole, it is more convenient to use compared to existing welding manner, more there is universality, and connect stronger.
It is a kind of bimetallic material that copper, which covers steel copper and covers steel earthing pole, high-intensitive, excellent elastic, the biggish heat with steel
Resistance, and has the excellent conductive performance and excellent corrosion resistance of pain, is that copper covers the complete of steel ground connection pole strength and corrosion resistance
Beauty combines, and is that good, at low cost, the easy for construction copper of earthing effect covers steel earthing pole.Due to the kelvin effect of electric current, conductive capability
By force, corrosion resistance is splendid, and since used steel have high tensile strength, can directly be driven underground, produce
Moral character, which can be fully achieved, does not cross UL467-2004 standard.
