Patent ID: 7360922

Claim:
A light tube assembly comprising: a light tube having an insertion extending from an end thereof and two protrusions extending from two sides of the insertion, two conductive members connected to a surface of the insertion; a stabilizer having a tubular body and two grooves defined axially in the tubular body; an end cap rotatably located on a first end of the tubular body and having two pawls extending from an underside thereof, an elongate through hole defined through the end cap; a core received in the tubular body and having an elongate receiving hole defined therein which communicates with the elongate through hole of the end cap, a first recess and a second recess defined in two facing insides of the receiving hole respectively, a positioning block protruding from an inner periphery of the second recess, the insertion of the light tube extending through the elongate hole of the end cap and inserted into the receiving hole, the two protrusions on the insertion being stopped by the positioning block of the second notch, two engaging recesses defined in an outer periphery thereof and the two pawls of the end cap engaged with the engaging recesses so that the end cap is connected to a first end of the core; a base connected to a second end of the tubular body and having two curved slots defined in a surface thereof, two copper members on the tubular body being slidably engaged with the two curved slots, two notches defined in a face of the base; two locking pins inserted into the two grooves of the tubular body, each locking pin having an inclined surface defined in a first end thereof and a tongue extending axially from a second end of each locking pin the two respective tongues of the two locking pins removably inserted into the notches of the base, each locking pin cooperated with a spring which biases the locking pin at a high position such that the inclined surface is in contact with the pawl corresponding thereto, and a positioning device located between the end cap and the core to set the end cap at a first position, a second position and a third position relative to the core, in the first position, the two respective second ends of the locking pins being not inserted into the base and the through hole of the end cap being not in the first recess so that the insertion of the light tube cannot be inserted into the receiving hole of the core and the base can be removed from the tubular body, in the second position, the two respective second ends of the locking pins being inserted into the base and the through hole of the end cap being in alignment with the first recess so that the insertion of the light tube can be inserted into the receiving hole of the core, in the third position, the two respective second ends of the locking pins being inserted into the base and the insertion of the light tube being rotated with the end cap and the protrusions being stopped by the positioning block so that the light tube is secured to the core.
