Abstract

A socket and bulb snap fastener for Christmas light strings includes at least one T-shaped tongue and a corresponding number of receiving means. The T-shaped tongue with a shoulder formed adjacent to a free end of the tongue is formed on an upper margin of a periphery of a socket of the bulb string for a Christmas tree. A V-shaped groove is formed on an upper side of each T-shaped tongue at an end opposite to the free end of the tongue and extends transversely across a length of each tongue. The receiving means is formed, corresponding to each T-shaped tongue, in the vicinity of an upper margin of an insert of the bulb string. The receiving means includes a compartment for receiving the tongue and a path through which the tongue is passable.

Claims

1. A socket and bulb snap fastener for Christmas light strings, comprising a socket and a bulb, said bulb comprising a lighting element and an insert having two leads mounted thereon which are electrically connected to said lighting element, a hole being centrally formed on said socket for receiving said insert, the improvements further comprising:

at least one substantially T-shaped tongue of insulating material being formed on an upper margin of a periphery of said socket, each T-shaped tongue having a shoulder formed adjacent to a free end of said T-shaped tongue, a V-shaped groove being formed on an upper side of each said T-shaped tongue at an end opposite to said free end of said tongue and extending transversely across a length of each said tongue;

a corresponding number of flexible receiving means of insulating material being formed, relative to each said T-shaped tongue, in the vicinity of an upper margin of said insert, each receiving means comprising two mirror image L-shaped protrusions which together form a compartment and a path slightly less wide than a width of said T-shaped tongue, each said T-shaped tongue being engageable with each corresponding receiving means by bending said T-shaped tongue upwardly about said V-shaped groove and snapping each said T-shaped tongue into said compartment via a corresponding path such that said shoulder of each said T-shaped tongue abuts an upper surface of both said protrusions.

2. A socket and bulb snap fastener for Christmas light strings, comprising a socket and a bulb, said bulb comprising a lighting element and an insert having two leads mounted thereon which are electrically connected to said lighting element, a hole being centrally formed on said socket for receiving said insert, the improvements further comprising:

at least one substantially T-shaped tongue of insulating material being formed in the vicinity of an upper margin of said insert, each T-shaped tongue having a shoulder formed adjacent to a free end of said T-shaped tongue, a V-shaped groove being formed on a lower side of said T-shaped tongue at an end opposite to said free end of said tongue and extending transversely across a length of each said tongue;

a corresponding number of flexible receiving means of insulating material being formed, relative to each said T-shaped tongue, on an upper margin of a periphery of said socket, each receiving means comprising two mirror image L-shaped protrusions which together form a compartment and a path slightly less wide than a width of said T-shaped tongue, each said T-shaped tongue being engageable with each corresponding receiving means by bending said T-shaped tongue downwardly about said V-shaped groove and snapping each said T-shaped tongue into said compartment via a corresponding said path such that said shoulder of each said T-shaped tongue abuts a lower surface of both said protrusions.
