Abstract
A socket is provided for an LED light string and is formed by jointing two unsymmetrical casing members through thermal fusion by application of ultrasonic wave to thereby securely combine with electrical wires and a luminous element. The first and second casing members are provided with raised-and-recessed inter-engageable structures including holes and protrusions and multiple tiny bosses that is thermally fusible through application of ultrasonic wave for adhesion purposes. The first casing member includes a receiving channel for receiving electrical wires therein and the second casing member includes hold-down blocks and holding blocks for holding the electrical wires in position.
Claims8
A socket for an LED light string, comprising a first casing member and a second casing member that are unsymmetrical to each other and are made of a fusible material;
- wherein the first casing member has a first jointing surface in which a wire receiving channel is formed, the first casing member comprising a first projecting portion formed on and extending from a side surface thereof, the first projecting portion forming two grooves and a rib arranged between the two grooves, the rib being arranged to divide the wire receiving channel into two isolated sections, the first casing member comprising retention holes formed in the first jointing surface;
- wherein the second casing member has a shape complementary to the first casing member and has a second jointing surface that is jointed to the first jointing surface so that the first and second casing members collectively form the socket, the second casing member comprising a second projecting portion formed on and extending from a side surface thereof, the second projecting portion forming a slot in which the rib of the first projecting portion is receivable, the second casing member comprising a plurality of retention protrusions formed on the second jointing surface to be respectively receivable in the retention holes of the first casing member;
- and
- wherein the inter-engageable raised-and-recessed structures provided on the first and second casing members allows electrical wires and a luminous element to be clamped between the casing members, which are then securely fixed together through thermal fusion by application of ultrasonic wave.
