Abstract: The present invention provides an attachment base for a lighting unit of a decorative lighting string comprising an upper base member inserted with an LED lamp and mounted onto an lower base member; the upper base member comprising locking hooks extended downward from two lateral sides of a bottom portion thereon; the lower base member comprising buckle holes adjacent to a bottom portion on two lateral sides corresponding to the locking hooks; characterized in that inner bottom surfaces of rear of the two buckle holes on the lower base member comprise blocking plate; a distance between the blocking plate and the buckle hole is slightly greater than a thickness of the locking hook. With such blocking plates, once the locking hooks are secured onto the buckle hole, the locking hooks abut the blocking plate to prevent the looking hook to disengage from the buckle hole under external forces.

Abstract: A light of a light string includes a receptacle having upper and lower sections. The upper section includes a support plate on which an LED straddles. The lower section includes therein a separation board and two stop boards having a wedge-like shape arranged at each side of the separation board. The pins of the LED extend into the lower section and each positioned against an upright face of the separation board and the stop boards. Metal cores of electrical wires that are partially stripped are received between the stop boards to contact the pins of the LED. A bottom lid having holding board provided thereon is coupled to the lower section, so that the holding boards force the metal cores of the electrical wires into tight engagement with the pins of the LED by being fixed between the separation board and the stop boards.

Abstract: A connection seat of bulb socket of decorative lamp string includes a main body having upper and bottom portions. The top portion includes a partition board on which an LED is seated with two terminals on opposite sides of the partition board. The bottom portion has a partition board and two stop boards having inside inclination surfaces. The terminals of the LED are arranged to extend into the bottom portion and positioned against the partition board of the bottom portion. A power cord has two conductors respectively received between the partition board and the stop boards and in engagement with the two terminals of the LED. A bottom cap is mounted to the bottom portion in such a way that two raised bars of the cap push the core conductors to securely fix the core conductors and the terminals of the LED between the partition board and the stop boards.

Abstract: A socket assembly is provided for a miniature light bulb set, including a socket body, a base member that receives power cords set thereon, and a holder that receives and holds a light bulb. The socket body has a bottom portion having front and rear sides forming cord cavities each of which forms a rim to form the structure for positioning and retaining the cord. The base member has left and right sidewalls each forming a retention block that projects outwards and has an increased thickness of material for forming the structure for coupling with the socket body.

Abstract: Disclosed is a structure of bulb socket of decorative light string. The socket forms an accommodation chamber for accommodating electrical wires. The accommodation chamber has top and bottom walls respectively forming opposing channels. The electrical wires have conductive plates mounted thereto and the conductive plates are insertable, in a vertical condition, through the channels into the accommodation chamber for being subsequently received and retained in retention slots formed inside the accommodation chamber. This allows the operation of assembling the socket and the electrical wires to be performed automatically with machines.

Abstract: The present invention is to provide an improvement of soft head structure in the decoration lamp string. It mainly is that the soft head is set with two groove rails on the upper and lower wall surfaces of accommodating grooves for laying the conductive wires, and the conductive copper plates in conductive wires are put in the accommodating grooves by a vertical way from the groove rails and snap-clip on the linking grooves of accommodating grooves. Therefore, the combining of conductive wires and soft head can be suitable to be operated through the automatic machinery.

Abstract: A lamp structure of a dual-wire lighting string includes an illuminator, a base, a socket, and a bottom member. The socket receives the base to which the illuminator is coupled in a top opening and forms therein positioning slots respectively receiving and retaining piercing conductive plates. A power cord is supported and forced by the bottom member into an open bottom of the socket to have the conductive plates piercing wires of the power cord to electrically engage inner conductive cores of the wires. Thus, the assembling of the lamp and the power cord can be carried out in an automatized manner with machines and the manufacturing costs can be reduced.
