Abstract

A glue-free light emitting diode (LED) guardrail tube with a plug comprises a shell, a light source module, a self-locking power wire, a plug, a fixing ring and a plug waterproof ring. A wire-penetrating hole is arranged on the bottom of the plug, and the self-locking power wire penetrates through the wire-penetrating hole and then is connected with the light source module. A control groove is arranged beside the wire-penetrating hole, and a guide bit is arranged on the control groove. A guide angle and a shell-inserting groove for embedding the shell are arranged in the plug waterproof ring, and no gap is arranged between the outer lateral surface of the fixing ring and the plane of a side of the plug waterproof ring, wherein the guide angel is arranged at the side. Contact surfaces of the plug and the plug waterproof ring all have a 0.5-millimeter interference, a notch for inserting a printed circuit board (PCB) is arranged on the guide bit, an opening for avoiding the PCB is disposed on the shell-inserting groove, and the notch for inserting the PCB is opposite to the opening for avoiding the PCB. The glue-free LED guardrail tube with the plug reduces production cost, enhances product yield and ensures a long service life of an LED guardrail tube.
