[0002] The crimping wiring terminal is a kind of accessory product for realizing electrical connection in power system, and is often used for the connection of electrical equipment and cable. It includes wiring rack, multiple wiring cavities on the wiring rack, wiring board, wire pressing screw, the wiring board is at the bottom of the wiring cavity, the wiring board is connected with the conductive plate of electrical equipment, and when using, the cable with skin peeled off is inserted into the wiring cavity, and the wire pressing screw is rotated to press the front part of the cable on the wiring board, to realize electrical connection.

[0003] The Chinese invention patent with publication number CN218958030U discloses a wiring terminal board structure with good protection effect. When wiring, the wire head at one end of the cable is inserted into the wire pressing groove, the staff twists the screw rod, then the screw rod and the screw groove are screwed, the screw rod is driven to descend, the screw rod drives the wire pressing plate at the bottom to move down synchronously, until the wire head in the wire pressing groove is pressed tightly, to realize the wire pressing effect. However, since the wire pressing plate and the screw rod are connected as a whole, the wire pressing plate will also rotate during the descending process of the screw rod, and when the wire pressing plate contacts the wire head of the cable, it needs to continue to descend the wire pressing plate to press it tightly. However, the wire pressing plate will still rotate synchronously with the screw rod during this continuous descending process, which may cause the wire head to be torn off during the rotating process. Therefore, we propose a wiring terminal board structure convenient to protect to solve the above problems. UTILITY MODEL CONTENTS
