程を多く要し、コストの高いものであつた。 Conventionally, this type of plug adapter has an insulating housing, an insulating base is fitted into the opening of the insulating housing, and a plug is attached to the surface of the insulating base to protrude outside the housing, and the plug is brought into contact with the insulating base. It was common for a contactor to be housed in a housing to be attached to the back side of an insulating stand. (For example, Utility Model Publication No. 53-23575) However, in this type of conventional adapter, it is necessary to manufacture the insulating stand and the insulating housing using separate molds, and in addition, the contactor inside the housing and the plug protruding outside the housing are required. Moreover, since screws are also used to connect the insulating stand and the housing, the number of parts is large, and many assembly processes are required, resulting in high costs.

のである。 The plug adapter of the present invention is constructed as described above, and includes a single contact, one end of which is housed in an insulating housing, holds a round bar plug, and has the other end protruding to be inserted into a blade socket. It has a plate-like shape with a fork-type connector part integrally molded at one end, which significantly reduces the manufacturing cost compared to conventional methods in which the plug receiving part and the plug part were formed separately and combined. and their assembly is simplified, and since the insulating housing is made by joining a pair of halves of the same shape, the entire housing is made up of one type of housing part, and its manufacture is significantly simplified. At the same time, the engagement protrusion and the engagement hole have a structure that locks the hook and the step, so they do not come off easily, and the engagement hole is opened through the half body, and the inner surface of the step is attached to the housing surface side of the step. By engaging the hook portion of the engagement protrusion, the engagement can be released using a jig.
Even if an incorrect assembly occurs, it can be corrected, and since both halves are connected to each other by a total of four engaging projections, two from one side, it is not possible to uncouple the two halves from only one side. This is impossible, and the live wires are not exposed during use, resulting in increased safety.
