1. An electrical connector comprising:

  • a male insertion piece having;

    an insulation base;

    an insulation tube being hollow and formed on one end of the insulation base;

    an outer electrode securely mounted around a periphery of the insulation tube; and

    a conductive needle mounted in the insulation tube;

    a female insertion piece having;

    an insulation sleeve having a guiding slot formed inside the insulation sleeve for the insulation tube to be inserted into the guiding slot;

    an outer connection electrode mounted inside the insulation sleeve, the outer connection electrode mounted around and contacting a periphery of the outer electrode of the male insertion piece; and
