Abstract:
An electrical heating wire assembly comprising:an electrical heating wire including a bundle of electrical heating filaments and an insulator sleeve that is sleeved on said heating filaments, said heating wire having a connecting end; an electrical conductive wire including a core and a protective sleeve that is sleeved on said core and that has a connecting end, said core having a connecting end that is exposed from said connecting end of said protective sleeve; and a connector interconnecting said heating wire and said conductive wire and including a conductive body and an insulator watertight sleeve, said conductive body including a block portion that extends in a longitudinal direction and that has a conductive wire-connecting end, a heating wire-connecting end opposite to said conductive wire-connecting end, and a recess extending inwardly from said conductive wire-connecting end toward said heating wire-connecting end in the longitudinal direction, said recess receiving and being connected to said connecting end of said core of said conductive wire, said conductive body further including a pin portion that is reduced in cross-section relative to said block portion, that projects from said heating wire-connecting end in the longitudinal direction, and that is inserted into said insulator sleeve at said connecting end of said heating wire in the longitudinal direction, said insulator first watertight sleeve extending in the longitudinal direction and being sleeved on said conductive body, said connecting end of said heating wire, and said connecting end of said protective sleeve so as to seal said conductive body, said connecting end of said heating wire, and said connecting ends of said protective sleeve and said core of said conductive wire.
