In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a PCB-type connection terminal comprising: the terminal shells are arranged side by side, wiring holes are respectively arranged in the terminal shells, conductors are arranged in the wiring holes, the inserting pins of the conductors extend out of the lower ends of the terminal shells, a pressing bolt matched with the conductor is arranged in the terminal shell at the upper end of the wiring hole in a penetrating way, an insulated winding sleeve is arranged on the terminal shell at the outer side of one end of the wiring hole penetrating through the terminal shell, a through hole communicated with the wiring hole is arranged in the insulating winding sleeve, an open slot communicated with the through hole is arranged at one side of the insulating winding sleeve, a spiral winding groove is arranged on the outer side of the insulated winding sleeve, a plurality of lead fixing cloth belts are uniformly arranged on the outer side of one end of the insulated winding sleeve away from the terminal shell, a first bonding layer is arranged on each lead fixing cloth belt, and a second bonding layer matched with the first bonding layer is arranged on the terminal shell on the outer side of the insulating winding sleeve.

Preferably, the diameter of the through hole is larger than that of the wire connection hole.

Preferably, the spiral winding groove has a semicircular structure.

Advantageous effects

The utility model provides a PCB formula binding post. Compared with the prior art, the method has the following beneficial effects: can reserve the wire insulating part of certain length through the winding mode on the terminal casing, at the in-process of later stage maintenance, change, if wire metal tip damages can follow some wire insulating parts of screwing out in the spiral winding recess and use, make wire metal tip can continue to be connected with binding post, need not to rearrange wire, convenient to use.
