Abstract: A cap for exposing or closing the prong openings of an electrical socket body can be mounted to the socket body with reduced number of parts, assembly man-hours and costs. The electrical socket body 1 is provided with guide grooves 7 and the cap 8 is formed with protrusions 12 capable of slidably engaging with the guide grooves 7 such that the cap 8 can be rotatably mounted over the socket body 1, whereby the cap 8 can be rotated to expose or close the prong openings in the socket body 1. Therefore, the cap 8 can be mounted over the socket body 1 without using conventional rivets and washers.

Abstract: A socket body 3 comprises a socket-forming section 4 having a mounting groove 6 around the outer periphery thereof. A cap 7 is integrally formed with a ring-shaped mounting portion 13 through a tether 12. The cap 7 may be mounted on the socket body 3 by engaging the mounting portion 13 in the mounting groove 6. Mounting the cap 7 on the socket body 3 requires no fastening members such as screws, thereby reducing the number of parts thereof and the number of assembly steps in comparison with those which require fastening members.
