Abstract

A knitting structure of power-supply wires in ornamental lamp, which mainly comprises several lamp strings in parallel to form into a large net-shaped ornamental lamp; the sockets of every lamp string are connected, in series, with a plurality of short power-supply wires to form into a single-wire lamp string; the short power-supply wires in each single-wire lamp string are twisted together with a knitting cord from the first socket to the last socket thereof so as to form into a lamp string assembly having a better tensile strength.

Claims

1. A knitting structure of power-supply wires in ornamental lamp comprising mainly several lamp strings connected in parallel to knit into a large net-shaped ornamental lamp, and each said lamp string including:

a plurality of short power-supply wires and each said wire connected between two sockets so as to form into a single-wire lamp string, of which the first and the last sockets connected with two main power-supply wires respectively and a plug;

a knitting cord without copper wire twisted with, from the first socket, said short power-supply wires of said single-wire lamp string so as to form into a lamp string assembly having a better tensile strength;

both ends of said lamp string left with a suitable length of knitting cords;

a fastening ring mounted on a rectangular base of said socket, and both sides of said fastening ring furnished with clamp grooves for receiving and positioning said knitting cords respectively;

said knitting cord without copper wire mounted between said lamp string assemblies, and twisted from the first socket of a lamp string, and mounted via clamp grooves between two diagonal sockets of two adjacent lamp string assemblies until the last socket of said lamp string assembly.

2. A knitting structure of power-supply wires in ornamental lamp as claimed in claim 1, wherein knitting and positioning structure are done by means of two symmetrical retaining rings on both sides of said socket, and said retaining rings used for retaining said short power-supply wires or knitting cord of said lamp string assembly.

3. A knitting structure of power-supply wires in ornamental lamp comprising several lamp strings connected together in parallel to form into a large ornamental screen light, and each said lamp string including:

a short power-supply wire connected between two sockets, and a plurality of said short power-supply wires connected between every two sockets respectively to form into a single-wire lamp string, of which the first socket and the last socket connected with two main power-supply wires respectively and a plug;

a knitting cord without copper wire twisted with said first socket of said single-wire lamp string so as to form into a lamp string assembly with a better tensile strength;

both ends of said lamp string assembly left a suitable length of knitting cord;

a reverse point of said lamp string being bundled up as a fastening point;

said knitting cords left on both ends of said lamp string assembly to be connected with a hook or a ring.
