Terminal for assembling wires of different diameters

A terminal for assembling wires of different diameters comprising:

• a base having a rectangular shape;
• a front end thereof having an extending tongue;
• a lower side of the extending tongue having an open section and a rear side thereof having a press section, two sides of the press section having buckling grooves;
• a plurality of recesses formed in the press section, ends of the recesses forming a stop, each recess extending to the extending tongue and then having a penetrating positioning groove;
• piercing conductive pieces having shapes approximately matching and installed in the recesses of the press section of the base and penetrating the positioning grooves, front sections of the pieces having stop blocks and rear sections thereof having a large piercing rod and a small piercing rod;
• front ends of the piercing conductive pieces passing into the penetrating positioning grooves and connected to the stop block so that the front ends of the piercing conductive pieces are exposed out of the opening section below the extending tongue of the base;
• rear sections of the piercing conductive pieces located in the recess whereby the piercing conductive pieces are combined to the base;
• and
• a buckling press having a shape similar to the press section of the base;
• two sides of the buckling press having hooks engaged with the buckling grooves;
• a lower side of the buckling press having plurality of large wire grooves and a plurality of small wire grooves which are equal in numbers and aligned with the recesses and piercing conductive pieces;
• middle sections of the large wire grooves having small wire slots;
• the buckling press having through holes to accommodate the large piercing rods and small piercing rods.
