Abstract

According to one embodiment, a plug includes four terminals arranged around a core shaft at substantially equal intervals, a housing that supports proximal ends of the four terminals, and a cylindrical cover fixed to the housing such as to surround the four terminals. The four terminals include two power terminals and two ground terminals, and at least the two power terminals have insulating coating layers respectively at their distal end portions.

Claims

1. A plug comprising:

four terminals arranged around a core shaft at substantially equal intervals;

a housing that supports proximal ends of the four terminals; and

a cylindrical cover fixed to the housing such as to surround the four terminals;

wherein the four terminals include two power terminals and two ground terminals, and

at least the two power terminals of the four terminals have insulating coating layers respectively at their distal end portions.

2. The plug according to claim 1, wherein the coating layers are each formed by applying an insulating resin on the respective distal end portion.

3. The plug according to claim 2, wherein the coating layers are formed to have a length of ⅓

or less but ⅛

or more of an entire length of the terminals.

4. The plug according to claim 2, wherein the coating layers are formed of a fluoropolymer.
