The invention discloses an electrical connection short-connected piece with the characteristic of repeated pin usage. The electrical connection short-connected piece comprises an insulator, a conductor and conductive pins. The conductor is coated inside the insulator. A plurality jacks are formed in the bottom of the insulator along the length direction. An elastic protrusion is arranged at one side of each conductive pin; the upper part of the conductive pin is inserted into the bottom of the insulator along the jack; and circular holes matching the elastic protrusions are formed in the sideof the lower part of the insulator. With the electrical connection short-connected piece with the characteristic of repeated pin usage, problems that pins can not be selected and installed flexibly for the short-connected piece and fixation and dismounting can not be carried out quickly are solved.
