Abstract
An electrical connection mechanism used in a miniature light bulb string mainly comprises a block or plug that can be inserted into the lower portion of a bulb holder shell. The block or plug is provided with a U-shaped conductor plate that presses against two opposite conductive terminals when it is seated in the shell to form an electrical connection between the terminals. Thus when one of the light bulbs is in malfunction, electrical current in the miniature light bulb string still can be maintained.
Claims2
An electrical connection means used in a decorative miniature light bulb string comprising a connection sleeve with a miniature light bulb seated in a top end thereof and a slot formed in a bottom end of tie connection sleeve, a coupling block having a protrusion formed on an upper end and covered on a lower end with a U-shaped conductor plate and integrated with a light bulb holder shell by the engagement or the slot with the protrusion, and two conductive terminals oppositely disposed in the holder.
An electrical connection means used in a decorative miniature light bulb string comprising a connection sleeve, a miniature light bulb, a holder shell and a sealing plug provided in two sides thereof with round grooves and covered on a top end with a U-shaped conductor plate;
- said plug being inserted into the holder shell and said U-shaped conductor plate thereby being brought into contact with respective conductive terminals disposed in the side grooves while said grooves respectively press against electrical wire to achieve a waterproof effect, said U-shaped conductor plate providing a current path in parallel with said miniature light bulb.
