ABSTRACT:
This invention relates to a safe light bulb socket structure mainly used for a C7 or C9 type light bulb. The socket shell of the socket structure according to the invention has an extended thin non-rigid sheet or an extended thin displaceable rib formed on its top and a thin annular appendage integrally molded on the opening at its lower end. When the socket shell is assembled with a light bulb and a socket cap, the thin sheet and the thin annular appendage will fill all leaks at the joining area, producing a watertight effect. In addition, two contact plates are arranged parallel to the electrical wire trench of the socket, with the upper ends thereof piercing into the plastic sheath of electrical wires and the lower ends thereof touching the tip and the ring contacts of the light bulb respectively. With this arrangement, the bad influence of contact plates on the joining of the socket shell and the light bulb, which is frequently found in a prior art socket structure, can be avoided.
