Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a socket with a cover, and is concerned with a socket cover for a socket used for, for example, line-type lighting, in which a straight tube lamp such as a fluorescent lamp is attached. This invention relates to a fitting and holding structure.

(Prior art) The socket used for the line type lighting system has
As shown in Figures 1 and 2, attach the socket cover C to the socket body mounting body B to which the socket body A is attached.
A structure has been proposed in which the
133882). The socket body mounting body B of this socket consists of a fixing plate part D, a side plate part E that curves in an arc shape downward from both sides of this fixing plate part D, and a side plate part E that is folded inward from the lower end of the side plate part E to face each other. A substantially semi-cylindrical socket mounting portion G consisting of a curved socket mounting portion F, and a substantially annular lid fitting formed at the rear end of this socket mounting portion G to have substantially the same curved surface as the side plate portion E. A structure is adopted in which a socket cover C is fitted into the lid fitting part H and the side plate part E of the socket mounting part G.

(Problems to be Solved by the Invention) In the structure of the conventional socket with cover shown in FIGS. As shown in the figure, the socket cover C tends to be tilted, resulting in a poor appearance. For this reason, it is conceivable to form the outer shape of the socket body A to be attached to the socket body attachment body B into a curved surface that is approximately the same as the side plate part E of the socket attachment part G, but the socket body A is large and does not require the use of a special socket body A. Not,
It has the problem of being expensive.

The present invention was devised in view of the above-mentioned problems, and includes a substantially annular cover fitting portion that protrudes from a portion of the mounting plate portion of the socket main body mounting body and is continuous with the curved surface of the side plate portion. The socket cover fitted to the mounting body is held by the lid fitting part, side plate part and cover fitting part of the socket main body mounting body to prevent the socket cover from being tilted by external force etc. and to prevent the appearance from being damaged. To provide a socket with a cover that can be obtained at low cost without causing any problems, increasing the versatility of the socket, allowing the use of a small socket.
