[0024] like Figures 1 to 4 As shown, the utility model is a high-strength conductive rod, characterized in that it includes a conductive rod body 1, a connecting block 2 is provided at the lower end of the conductive rod body 1, a cross groove 21 is provided on the inner side of the lower end of the connecting block 2, a screw head 3 is provided at the lower end of the connecting block 2, and a joint 4 is provided at the upper end of the conductive rod body 1, an equipment hole 41 is provided inside the joint 4, a graphite conductive rod 11 is provided inside the conductive rod body 1, and a rubber insulating layer 12 is provided on the outer side of the graphite conductive rod 11.

[0025] Furthermore, a cross protrusion block 31 is provided at the contact position between the screw head 3 and the connecting block 2, and the cross protrusion block 31 corresponds to the size and position of the cross groove 21. When a problem occurs with the conductive rod body 1, the conductive rod body 1 can be pulled out and replaced through the shape corresponding to the size and position of the cross protrusion block 31. An external thread is provided on the outside of the screw head 3.

[0026] Furthermore, a heat dissipation channel 13 is provided between the rubber insulating layer 12 and the graphite conductive rod 11, and heat dissipation holes 121 are evenly provided on the outer side of the rubber insulating layer 12, which increases the heat dissipation performance, effectively increases the service life of the component and reduces the danger caused by overheating of the component.

[0027] Furthermore, the entire body of the graphite conductive rod 11 is in the shape of a spiral column, so that when over-current occurs, the load current rises evenly in the spiral shape, thereby improving the overall load-bearing performance.

[0028] Furthermore, the outer side of the connecting block 2 is provided with a same rubber insulating layer 12 to increase safety.

[0029] Furthermore, a conductive sheet 32 ​​is provided at the lower end of the screw head 3 to increase the strength of current conduction.

[0030] Working process: first, connect the conductive rod body 1 to the external device through the external thread of the screw head 3, and then connect the device that needs to transmit current through the equipment hole 41 inside the joint 4 to perform conductive work. When there is a problem with the conductive rod body 1, the conductive rod body 1 can be pulled out and replaced through the shape of the cross protrusion block 31 and the cross groove 21 corresponding to the size and position. The screw head 3 can continue to be used to reduce consumption. When replacement is not required, the component provides dual stability of threaded connection and mortise and tenon connection. During normal power overload, the graphite conductive rod 11 evenly increases the load current through the spiral shape, improves the overall load-bearing performance, and is not easy to be damaged. When the circuit strength is too high, the threaded column shape can avoid current accumulation on the surface, effectively preventing creepage, and improving overall safety and strength. The conductive magnetic sheet 32 ​​at the lower end of the screw head 3 can increase the intensity of current conduction.

[0031] Secondly, the heat dissipation channel 13 between the rubber insulating layer 12 and the graphite conductive rod 11 and the heat dissipation holes 121 outside the rubber insulating layer 12 increase the heat dissipation performance, effectively increase the service life of the components and reduce the danger caused by overheating of the components.
