However, in the case of such conventional lighting equipment, when assembling it, it is necessary to insert your hand between the socket cover 6 and the socket body 5, and insert the cord stopper 18 into the insertion opening 16 from inside the socket cover 6. , it is necessary to introduce the terminal portion of the power cord 1 into the inside of the socket cover 6 in advance with a certain amount of allowance. However, if the end portion of the power cord 1 is introduced inside the socket cover 6 with sufficient dimensions as described above, when the socket cover 6 is attached to the upper surface of the socket main body 5 by overlapping, the periphery of both of them will be removed. Lead wires 1a, 1a of power cord 1 between the parts
The problem was that the parts were often bent and pinched, which made the work of installing them quite troublesome and greatly reduced efficiency. In addition, in the assembled state, the lower side of the cord stopper 18 is left wide open. Therefore, if the power cord 1 is pushed into the inside of the socket cover 6 with an impact, the cord stopper 18 will be pushed into the socket cover 6 due to the impact. There was a risk that the insertion hole 16 would move inward and become detached from the insertion opening 16.

[Purpose of invention]

This idea was made with attention to these points, and its purpose is to prevent the socket cover from overlapping and attaching to the top surface of the socket body.
The lead wire of the power cord placed inside the socket cover will not be caught between the peripheral edges of the two, and the cord stopper will not come off from the insertion opening even if the power cord is pushed inside the socket cover. An object of the present invention is to provide a hanging type lighting fixture that avoids the need for
