Abstract: A connector includes a first connecting assembly and a second connecting assembly, wherein the first connecting assembly and the second connecting assembly are fitted with each other. The first connecting assembly includes a first inner core and at least two first electric wires, and each of the first electric wires is electrically connected in a first end portion of the first inner core. The second connection assembly includes a second inner core and at least two second electric wires, and each of the second electric wires is electrically connected in a first end portion of the second inner core. A second end portion of the second inner core is provided with a connecting portion, and the connecting portion is inserted in a second end portion of the first inner core, so that the first electric wire is in an electrical communication with the second electric wire.

Abstract: The present application provides a light string unit, including: a plurality of light-emitting bodies; and a conducting wire, configured to electrically connect the light-emitting bodies in series, opposite ends of the conducting wire being connected to positive polarity and negative polarity of an external power supply circuit or an external power source, respectively. Wherein, the conducting wire is a high-tensile conducting wire which includes: a conductive core wire; an insulated coating, configured to encapsulate the conductive core wire; and a tensile resistant cord, set inside the insulated coating and set parallelly or twisted with the conductive core wire to enhance the tensile strength of the conducting wire. In the present application, the tensile resistant cord enhances the tensile strength of the conducting wire, and completely reaches or even exceeds the requirement on tensile strength of a conducting wire in the UL 588 criterion and has a simplified structure.
