[0008] The upper end of the upper fixture plate is provided with at least two vertically arranged upper spring holes and upper guide holes.

[0009] The upper end face of the upper fixture plate is equipped with an upward floating plate.

[0010] The beneficial effects of this utility model are as follows: The punching fixture for a double-row pin connector described in this utility model includes a base plate, a lower fixture plate mounted on the upper end of the base plate, and a corresponding upper fixture plate mounted on the upper end of the lower fixture plate. The upper end face of the lower fixture plate is provided with a plurality of lower row pin clearance slots arranged in a row, and a lower punching knife is embedded in the pin clearance slots. The lower end face of the upper fixture plate is provided with an upper row pin clearance slot, and an upper punching knife is embedded in the upper row pin clearance slot. An intermediate punching plate is installed between the upper punching knife and the lower punching knife. This utility model features a lower fixture plate mounted on the upper end of a base plate, with a corresponding upper fixture plate mounted on the upper end of the lower fixture plate. The upper end face of the lower fixture plate has several row-shaped lower needle clearance slots, each containing a lower needle punch. The lower end face of the upper fixture plate has an upper needle clearance slot, each containing an upper needle punch. An intermediate needle punching plate is installed between the upper and lower needle punches. By utilizing the upper needle punch, lower needle punch, and intermediate needle punching plate, the upper and lower needle rows are simultaneously needle punched, greatly improving production efficiency. Therefore, this utility model has the advantages of novel design, simple structure, and the ability to perform double-row needle punching simultaneously, significantly improving production efficiency.
