Connection structure for connecting power cable and conductor lead-out rod, and connection device for connecting power cable and conductor lead-out rod

A connection structure, for connecting a power cable and a conductor lead-out rod, which connects a conductor part including a plurality of wires of a power cable to a conductor lead-out rod of a termination connection box, the connection structure comprising:

• a conductor part of a power cable;
• an adapter configured into which the conductor part is inserted through an open lower end thereof, the adapter being formed in a cylindrical shape, an upper end and the lower end of which are open;
• a conductor lead-out rod providing an accommodation groove into which the conductor part of the power cable inserted into the adapter is inserted into an opening in a lower end thereof, the conductor lead-out rod including:
• a stopper configured to prevent the adapter from being inserted above a predetermined height into the accommodation groove during the insertion of the conductor part of the power cable, the stopper being formed on an inner circumference of the accommodation groove;
• and
• a plurality of fastening holes the conductor lead-out rod comprising a body part providing the accommodation groove which has an opening in a lower end thereof and into which an upper end of the conductor part inserted into the adapter is inserted, the body part including a plurality of conducting fastening holes into which a plurality of conducting bolts are fastened are provided in an upper portion of the body part at predetermined intervals in a circumferential direction, and a plurality of fixing fastening holes into which a plurality of fixing bolts are fastened are provided in a lower portion of the body part at predetermined intervals in the circumferential direction;
• a plurality of conductive particles injected into an accommodation space in an upper portion of an upper end of the conductor part inserted into the accommodation groove of the conductor lead-out rod, the conductive particles being exposed via the accommodation groove during the insertion of the conductor part into the accommodation groove, thus electrically connecting the conductor part and the conductor lead-out rod;
• a plurality of conducting bolts configured to be fastened into the conducting fastening holes to apply pressure directly to the conductive particles injected into the accommodation space so as to reduce voids in the conductive particles and to electrically connect the conductor part and the conductor lead-out rod;
• and
• a plurality of fixing bolts configured to be fastened into the fixing fastening holes to fix the conductor part inserted into the accommodation groove.

A conductor connection device for connecting a conductor part of a power cable to a conductor lead-out rod, the conductor connection device comprising:
