Terminal block connector

The invention discloses a terminal block connector which comprises a front shell body, a back shell body and a conducting metal component. A wire inserting opening and a pulling cover at the top are arranged at the front end of the front shell body. The conducting metal component comprises a front elastic metal piece and a back metal piece. The top of the front elastic metal piece tilts upwards. The back metal piece is in a reversed-Z shape. A sheet-shaped protruding piece protrudes out of the top of the back metal piece. The top end tilting end of the front elastic metal piece is placed at the bottom of the protruding piece and is in tight contact with the bottom of the protruding piece. A protrusion block is arranged at the top of the front shell body. A groove is formed in each of the two sides of the protrusion block in a concave mode. A pulling cover handle is arranged at one end of the pulling cover. The other end of the pulling cover is branched into symmetrical pulling cover pressing pieces from the two sides of the pulling cover handle. Anti-sliding lines are arranged at the end of the pulling cover handle. The symmetrical pulling cover pressing pieces are inserted from the corresponding grooves respectively. Pressing ends which protrude to form acute angles are arranged at the bottoms of the pulling cover pressing pieces. Concave positions arranged corresponding to the pressing ends are arranged on the top side of the front elastic metal piece in a concave mode, and stair-shaped anti-sliding line grooves are formed in the surfaces of the concave positions.
