Abstract: Disclosed is an in-line socket device and its fabricating method. The in-line socket device is covered with a cover shell, and has a movable safety cover connected with one end of the cover shell. The socket device is composed of a base and a base cover, in which one end of the base is open and the other end has three plug sockets. A plurality of axial slots are formed inside the opened end for covering up wires, and terminals are provided within axial slots to make the crimping end and the bared wire to be clipped; accordingly, partial sections of the wires connected with the terminal crimping end can crimp the bared wire through peeling off the PVC cover layer of the section, so that the integrity of wires can be ensured and the problem of power consumption or fallen off from the connection can be prevented.

Abstract: A stretchable and shrinkable tree light string including a long trunk with many short pipes. The short pipes have one or many connecting rings. A base frame has a central axis to support the long trunk to stand up straight. Multiple branches connect at one end with a pin to the connecting ring on the short pipe. These branches use the connecting ring as a base pivot point. The branches being centered on the long trunk to be able to stretch out to form a tree shape, and also to be able to fold up to reduce the volume. Single or many sets of light strings, composed of many lamp bulbs, lamp holders, electrical conductors and receptacles, are to be fixed on the branches to establish tree light strings.

Abstract: The present invention relates to a kind of decorative light strings with combination tree, including a long trunk to be composed of many short pipes, the height of tree lamp can be adjustable by the number of the short pipe; base frame is to use a support surface to erect the base frame and has a center axis to support long trunk to stand up right straight; multiple branches connect with the long trunk; single or multiple set of light strings, composed of many lamp bulbs, lamp holders, electrical conductors and receptacles, to be fixed on the branches to establish tree light strings.

Abstract: The present invention generally relates with filling air string unit in decorative lighting string. This filling air string which to make the lighting string to expandable or to shrinkable with lighting device and the firm device. This filling air string is made up from soften plastics which has a filling air room. The lighting string will made up into many different kind of shapes when volume expansion when expand and sufficient the air. The lighting string will minimize the volume when emit the air. This filling air volume has a gas room in the central that has some capacity for this lighting device. As this lighting device firm in the central of this gas room to be able to reveal any kind of shapes and clearly to showing the lighting string while rising this filling air string.
