The insulation sleeves are bonded in the die hot pressure casting mode, and the inner wall of each insulation sleeve is provided with a boss clamped to the copper lines, so that the insulation sleeves are positioned firmly, the insulation sleeves and the copper lines are bonded tightly, the insulation sleeves will not bend or disengage in the use process, the soft copper lines are effectively prevented from being broken, and safety of construction personnel is guaranteed.
Description
Technical field
The present invention relates to earth connection technical field.
Background technology
Earth connection is to be connected on the positions such as electric equipment shell timely by the circuit of various unsafe electric charges or leakage current derivation.In the maintenance process of transmission line, after line outage, must connect ground wire.High-voltage grounding wire is for circuit and Substation construction, for preventing from ensureing while closing on electrified body generation electrostatic induction electric shock or false switching the use of safety.In prior art, on earth connection, conducting wire folder and insulating bar become earth rod, earth connection is multiply annealed copper wire, in order to prevent the disconnected thigh of multiply annealed copper wire on earth rod, make in advance special rubber bush, rubber bush is sleeved on to multiply annealed copper wire and line nose junction, although the elasticity of rubber bush has protective effect, but the combination of itself and multiply annealed copper wire is not tight, repeatedly pulling in process, insulating sleeve is easily shifted or comes off, the easy bending of the multiply annealed copper wire of earth connection and line nose junction, cause the disconnected thigh of strand copper wire to affect earthing effect, to line maintenance, personnel form potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of earth rod, has insulating sleeve and earth connection and line nose terminal block and combines closely seamlessly, and in use not bending of insulating sleeve does not come off, and protective earthing annealed copper wire is burst adeciduate feature constantly.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of earth rod, comprises the line nose terminal block at wire clamp, earth connection and two ends thereof that insulating bar is installed; Described earth connection is the strand copper wire of coated outside insulated tube, the two ends of described strand copper wire are extruded respectively in the nostril of online nose terminal block, the line nose terminal block that is positioned at earth connection left end is connected with wire clamp bottom, and the line nose terminal block that is positioned at earth connection right-hand member is connected with ground connection band iron; Also be respectively equipped with insulating sleeve at earth connection both ends, described insulating sleeve is bonded in the periphery of earth connection and line nose terminal block junction by mold hot pressure injection.
The further improvement that the present invention is done is: the length of described insulating sleeve is between 80mm-100mm, and the wall thickness of insulating sleeve is between 3mm-5mm.Described insulating sleeve is electro-insulating rubber material.On described insulating sleeve, suit represents the colour band of circuitry phase.
The beneficial effect that adopts technique scheme to produce is: the present invention's cost simple in structure is low, pass through the extrusion bonded insulating sleeve of mold hot at ground connection annealed copper wire and line nose junction, inwall at insulating sleeve forms the boss being stuck in together on strand copper wire, make insulating sleeve firm position, with annealed copper wire close adhesion, good airproof performance, in use not bending of insulating sleeve does not come off, effectively prevent disconnected strand of annealed copper wire, whole earth connection has been played to effective protective effect, the misoperation when colour band of expression circuitry phase can prevent ground wire connection, workmen's safety is protected.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of the insulating sleeve extrusion bonded by mold hot.
As shown in the figure: 1 wire clamp, 2 insulating bars, 3 bolts, 4 line nose terminal blocks, 5 insulating sleeves, 6 represent the boss on the colour band, 7 earth connections, 8 ground connection band irons, 9 insulated tubes, 10 strand copper wires, 11 insulating sleeve inwalls of circuitry phases.
