摘要:
A securing mechanism used in Christmas light bulb series mainly comprises a light bulb socket having a pair of longitudinal guide rails formed on two side wall surface thereof and a plurality of transverse ribs disposed between two guide rails. The transverse ribs have a triangular cross section with an inclined top side and a horizontal bottom side. The securing mechanism also includes a U-shaped fastener that has horizontal locking ribs disposed on the inner wall surfaces on two ends thereof. The locking ribs have a cross section with a horizontal top side and an inclined bottom side. The fastener mounts on a support frame and holds on two sides of the socket to secure and locate a socket at arbitrary position along the support frame with a desired inclination angle.

The invention describes a decorative board associated with Christmas light bulb series, especially a combination of decorative boards with light bulbs having an enhanced decorative aesthetic visual effect. The decorative board according to the invention can have any proper shape or design. Arranged on the back of the decorative board are a plurality of fastening mechanisms that can easily connect with sockets of a light bulb series. With rays of light bulbs passing through the transparent decorative board, the decorative board produces a light diffusion effect and achieves decorative objects.

A lamp holder includes a hollow holder body having a top opening to receive therein a base of a bulb. The holder body has two contact terminals provided therein in a spaced manner to be corresponding to filament extensions of the base of the lamp for establishing electrical connection therewith when the bulb is inserted into the holder body. Electrical wires are inserted into the holder body through a bottom opening of the holder body to physically connect to the contact terminals. A lengthening support is provided to support the holder body, comprising a tubular member made of an insulating material, having a side wall with an open top side and an open lower side. A partition plate is fixed to the open top side to define two openings adjacent thereto. The partition plate is insertable into the holder body through the bottom opening of the holder body to hold the holder body thereon and to at least partially separate the wires from each other with the wires running through the tubular member to respectively extend into the holder body through the openings on the top side of the tubular member. Inverted V-shaped notches are provided on the side wall of the tubular member with a wide opening formed on the lower side of the side wall for fitting onto and mounting to for example a shoot of a tree.

An improved miniature light bulb socket provided with an insert to keep wire terminals separate. The socket mainly comprises a socket shell in which a Y-shaped insert is seated with two opposed protrusions engaged with the grooves of the socket shell. With such an arrangement the electrical wires and terminals extending into the socket can be kept separate effectively and prevented from their shorting. Further, the socket has a conductor pin disposed on the top of the insert and kept in touch with two electrical wire terminals and so the electrical circuit of a miniature light bulb series can be kept closed even if the light bulb on the socket is burned down. It can have an advantage that the light bulb series can still work even if some bulbs of the light bulb series fail. The improved light bulb socket structure according to the invention indeed enhances the practical value of a socket.
