PURPOSE:To provide a water-proof socket for construction work which can not possibly be damaged even if handled roughly, keeps surely water-proof and is manufactured easily with no need of much labor, long time, and high cost. CONSTITUTION:An electric wire 3 of a water-proof insulating cable 4 is spot- welded or soldered to a socket main body 2. The electric wire-attached socket main body 2 is set in prescribed molding dies and a fusible synthetic resin material is injected in the dies to form a synthetic resin housing 5 to cover the socket main body 2 and the water-proof insulating cable 4. The resulting body is taken out after the resin is hardened to give a water-proof socket 1 for construction work. |
