String lights structure

A novel string lights structure, wherein, comprising a power cord, a male connector connected to a first end of the power cord, and a female connector connected to a second end of the power cord;

• wherein, the power cord is equipped with a plurality of light bulbs arranged at intervals along the power cord;
• and the power cord comprises a positive lead and a negative lead;
• each of the plurality of light bulbs comprises a cap assembly, a light-emitting light source, and a light-transmitting bulb;
• the light-emitting light source is provided with an anode terminal and a cathode terminal;
• the light-transmitting bulb is internally formed with a bulb inner cavity opening upwardly;
• the cap assembly comprises a cap inner core, and a cap encapsulating part formed at a periphery of the cap inner core by overmolding;
• and the cap inner core comprises an inner core body, and an inner core top cover arranged at an upper end portion of the inner core body;
• the inner core body and the inner core top cover are made of rigid plastic parts;
• the power cord is tightly clamped between the inner core body and the inner core top cover;
• the inner core body is internally opened with a body mounting hole opening downwardly;
• the inner core body is provided with an anode connection terminal and a cathode connection terminal whose lower end portions extend into the body mounting hole, respectively;
• at upper end portions of the anode connection terminal and the cathode connection terminal are provided with a pointed penetration part protruding upwardly and in a spike shape, respectively;
• the pointed penetration part of the anode connection terminal penetrates a plastic sheath of the positive lead of the power cord, and is electrically connected to a core of the positive lead;
• and the pointed penetration part of the cathode connection terminal penetrates a plastic sheath of the negative lead of the power cord, and is electrically connected to a core of the negative lead;
• an upper end portion of the light-emitting light source is embedded in the body mounting hole of the inner core body, and the anode terminal of the light-emitting light source is electrically connected to the anode connection terminal, and the cathode terminal of the light-emitting light source is electrically connected to the cathode connection terminal;
• an upper end portion of the light-transmitting bulb is connected to a lower end portion of the cap encapsulating part, and a lower end portion of the light-emitting light source-extends into the bulb inner cavity of the light-transmitting bulb.
