In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a large-current wiring terminal, includes the terminal body, the top of terminal body has two at least first screws, the bottom of terminal body has two at least second screws, a plurality of first screw and a plurality of the second screw is longitudinal symmetry structure, this internal wiring hole that is equipped with of terminal, the both ends in wiring hole all communicate with each other with the external world, first screw with the second screw all with the wiring hole is linked together, the terminal body is close to be equipped with on the inner wall at wiring hole middle part and be the first direction arch and the second direction arch of dislocation structure from top to bottom, set up the external ventilation hole of intercommunication in the wiring hole, just two are located in the ventilation hole between the first screw.

Furthermore, the first screw hole, the second screw hole and the wiring hole are in a vertical crossing structure.

Further, the quantity of ventilation hole is two, two the ventilation hole is symmetrical structure.

Furthermore, a sponge sheet is arranged on the end face of the terminal body and bonded to the terminal body, and the sponge sheet shields one end of the ventilation hole.

Further, the terminal body is of a cuboid structure.

The utility model discloses following beneficial effect has: the terminal body is processed into a cuboid structure, so that heat dissipation is more balanced, heat dissipation speed is higher, two screws can be screwed on the top surface of the terminal body and used for fixing a thick copper wire special for large current, two screws can be screwed on the bottom surface of the terminal body and used for better fixing the wiring terminal on a circuit board, the contact surface between the circuit board and the wiring terminal is increased, large current can flow to the circuit board, and the wiring terminal is cuboid-shaped, so that the structure is simple, anti-interference, compact, small in shape, low in cost and capable of saving space; when the first guide bulge and the second guide bulge are connected with the copper wire, the first guide bulge and the second guide bulge play a role in limiting and guiding, the copper wire can be deformed, the offset position of the copper wire is reduced, and then the first guide bulge and the second guide bulge are fixed through screws, so that the connection stability is further reinforced; the cuboid structure of the terminal body is designed to occupy smaller space, so that the contact surface between the circuit board and the wiring terminal is increased, the heat emitted in the process of large-current transmission is reduced, and the stability and reliability of a power supply are improved; in addition, through the arrangement of the ventilation holes and the sponge pieces, heat generated at the wiring positions can be discharged through the ventilation holes, and the sponge pieces can ensure the humidity inside the sponge pieces.
