[0005] A square terminal block includes a housing body. There are several channels arranged in the housing body. Several wire access ports are arranged on the front side of the housing body, and the wire access ports are arranged in one-to-one correspondence with the channels. A wire clamping assembly is arranged in each channel. The guiding clamping assembly includes a copper pin, a copper square block, and a screw. The upper part of the copper pin is fixed in the channel, the lower part of the copper pin penetrates downward through the housing body, the copper pin is in an L-shaped structure as a whole, and the upper end of the copper pin is a top pressing plate;
[0006] The copper square block is located in the channel, and the copper square block can move up and down in the channel. The copper square block has a square opening, the top pressing plate is located in the square opening, a threaded hole is opened at the top of the copper square block, an internal thread is arranged at the top of the channel, and the thread directions of the internal thread and the threaded hole are opposite. The screw is connected in the internal thread at the top of the channel and the threaded hole.
[0007] Further, a cover plate is buckled on the top of the housing body.
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: The utility model uses a copper square block to replace the original punching and tapping of copper parts, and adopts a screw internal buckling type for fixation to avoid falling off and loss; using the copper square block to fix the conductive wire enhances the biting force and improves the overvoltage amount of the prior art. The utility model solves the defects of the existing products, does not need to damage the conductive copper parts, enhances the torque value, bites the conductive wire in all directions, adopts a screw internal buckling type protection measure, avoids the defect of the gasket spinning when being screwed, and makes the wiring more convenient.
