Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a socket cover that aesthetically covers the base and socket of a straight tube fluorescent lamp attached to a lighting equipment.

[Background technology]

As this type of socket cover, those shown in FIGS. 1 and 2 are proposed. In the figure, 1 is a lighting fixture body, 2 is a socket protruding from the lower surface of the lighting fixture body 1, 3 is a straight tube fluorescent lamp, and 4 is a socket cover. The socket cover 4 consists of a cover body 5 and a leaf spring 6 for attachment. The cover body 5 consists of a U-shaped peripheral wall 5a, an end wall 5b, and a flange 5c, and has a socket insertion opening 7 and a lamp insertion opening 8. The leaf spring 6 is formed in an Ω shape and is fixed to the bottom surface of the cover body 5 at the center with screws 9. By pushing the leaf spring 6 into the base 3a of the lamp 3 as shown in FIGS. 3A and 3B, the socket cover 4 is brought into a state in which the periphery of the socket insertion opening 7, that is, the upper end surface comes into contact with the lower surface of the device main body 1. Installed.

Since lamps 3 have various diameters such as 38 mm, 32 mm, and 28 mm, it is desirable that the socket cover 4 can be attached to any type of lamp 3. Therefore, the width A of the inlet portion of the leaf spring 6 must be extremely narrow so that spring pressure can be applied even to the lamp 3 having a minimum diameter of φ28. However, if the entrance width A is narrowed, the frictional force will increase in the ramps 3 of φ32 and φ38, and even if force is applied in the B direction as shown in FIG. 3A, the leaf spring 6 will not open in the C direction, and the socket cover will 4 could not be installed. In order to be able to install this, there is a method of reducing the overall width of the leaf spring 6 or reducing the wall thickness, but this reduces the overall spring pressure, so It becomes impossible to maintain a stable mounting state of the socket cover 4.

[Purpose of invention]

SUMMARY OF THE DISCLOSURE An object of this invention is to provide a socket cover which can be attached to straight fluorescent lamps of various diameters and which can provide a stable attachment state.

[Disclosure of invention]

The socket cover of this invention has a socket insertion opening and a lamp insertion opening extending from the socket insertion opening, and covers a socket for a straight tube fluorescent lamp that protrudes from the lighting equipment main body, so that the peripheral portion of the socket insertion opening is connected to the lighting equipment. a cover main body disposed in contact with the main body; a cover main body formed in a substantially inverted Ω shape and tapered in width; and a leaf spring fitted into the lamp inserted into the socket.

According to the structure of this invention, since the leaf spring is formed into a tapered shape, the tip of the leaf spring is easily bent in the opening direction when installed, and even if the width of the entrance part is made small, it is possible to easily push in a large diameter lamp. can. Further, since the leaf spring is made thinner only at the tip end, the overall spring pressure does not decrease much, and therefore, a secure attachment state can be maintained.

Embodiment An embodiment of this invention is shown in FIG. That is, this socket cover is formed by gradually tapering the width of the leaf spring 6'. Therefore, the width f at the tip of the leaf spring 6' is narrower than the width e at the center. The rest of the structure is the same as the socket cover 4 shown in FIGS. 1 to 3.

Since the leaf spring 6' is formed to be tapered in this way, the tip of the leaf spring 6' can easily bend in the opening direction during installation, making it easy to push in a large diameter lamp even if the entrance width A is small. Can be done. Further, since the leaf spring 6' is made thinner only at the tip side, the overall spring pressure does not decrease much, so that a secure attachment state can be maintained. Further, since the spring pressure can be finely adjusted by changing the rate at which the leaf spring 6' tapers, it is possible to easily design the spring pressure so as to obtain the optimum spring pressure.

[Effect of idea]

Since the socket cover of this invention has a tapered leaf spring, the tip of the leaf spring can easily bend in the opening direction when installed, and a large diameter lamp can be easily pushed in even if the entrance width is small. . Further, since the leaf spring is made thinner only at the tip end, the overall spring pressure does not decrease much, and therefore, a secure attachment state can be maintained.

As described above, since the leaf spring for clamping the lamp is formed into a tapered shape, it is possible to improve the installation workability while ensuring a stable installation state for lamps of various tube diameters.
