Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a technique for installing a socket cover in a straight tube fluorescent lighting fixture.

[Background Art] Conventionally, in order to improve the appearance of a straight tube type fluorescent lighting fixture as shown in FIG.
It is known that a socket cover 4 is fitted to the socket. In Figure 6, 1 is the instrument body, 2 is the socket base, and 3
b is the fluorescent lamp connection part provided in the socket part 3;
is a notch provided in the cylindrical socket cover 4, which is fitted into the socket base 2. Further, 7 is a fluorescent lamp. However, in the above-mentioned straight tube fluorescent lighting fixtures with socket covers, multiple lamps are often installed in a straight line as shown in Figure 7, and due to construction precision issues, the end of the socket cover 4 may be damaged at the butt part of the socket 3. There is a possibility that a gap 9 may appear between the socket cover 4 and the end of the socket cover 4.

[Purpose of the invention] The present invention was devised in view of the above conventional problems, and its purpose is to make the end of the socket cover flush with the end of the socket when used alone. It fits easily, and when multiple straight tube fluorescent lamps are installed in a straight line, even if the ends of the sockets are not in close contact, there is no gap in this area when viewed from the outside. The goal is to provide fluorescent lighting fixtures that can prevent light from emitting light.

[Disclosure of the Invention] The fluorescent lighting fixture of the present invention is a fluorescent lighting fixture in which socket parts 3 are attached to both ends of a fixture body 1 via socket bases 2 so as to face each other, and a socket cover 4 is fitted to the socket parts 3. In the instrument,
A notch 5 is formed at one end of the cylindrical socket cover 4, and a rib 6 is formed in the socket base 2 or socket portion 3.
, and when the socket cover 4 is fitted into the socket part 3 and the notch 5 is fitted into the socket base 2, and the back end of the notch 5 is in contact with the rib 6, the side end surface of the notch 5 of the socket cover 4 and the socket part 5 are connected. The rib 6 is made of synthetic resin and has a narrow width so that the rear end surface is flush with the rear end surface, and the rib 6 is made of synthetic resin and has a narrow width so that the inner end of the notch 5 of the socket cover 4 can dig in or the rib 6 can be scraped when the socket cover 4 is pushed hard. By adopting such a configuration, the above-mentioned object of the present invention is achieved. That is, in the present invention, even if the end surfaces of the socket parts 3 of adjacent fluorescent lamp lighting apparatuses do not come into contact with each other when the fluorescent lamp lighting apparatuses are arranged in a straight line, and a gap is created in this part, the socket cover 4 The end of the socket cover 4 is pushed in strongly so that the inner end of the notch 5 of the socket cover 4 bites into the rib 6, or the rib 6 is shaved, so that the end of the socket cover 4 protrudes from the end face of the socket part 3, and the end face of the adjacent socket cover 4 is pushed in. This is to hide the gap created between the end faces of the socket part 3.

The present invention will be explained in detail below with reference to Examples. Socket portions 3 are provided at both ends of the instrument body 1 with socket bases 2 interposed therebetween, and the socket portions 3 on both sides face each other. In the illustrated embodiment, the socket part 3 is composed of an outer case part 3a and a fluorescent lamp connection part 3b housed inside the outer case part 3a.
It is integrally formed from synthetic resin. A rib 6 protrudes from at least one of the outer case parts 3a of the socket base 2 to the socket part 3, and this synthetic resin rib 6 is provided facing the side into which a socket cover 4, which will be described later, is fitted, as shown in FIG. be. The socket cover 4 has a cylindrical shape and has a notch 5 formed at one end of its upper surface. 7 in the figure is a fluorescent lamp, and the fluorescent lamp connection part 3 of the socket part 3
b. The socket cover 4 is fitted into the socket part 3, and the notch 5 is fitted into the socket base 2, and the notch 5 is inserted into the rib 6.
The back end of the button hits. In this state, as shown in FIG. 4, the fluorescent lighting fixture is used alone, and in this case, as shown in FIG. The end portion of the socket portion 3 is set flush with the rear end surface of the socket portion 3. On the other hand, when a plurality of fluorescent lighting fixtures are used arranged in a straight line as shown in FIG. 5, they are installed so that the rear end surfaces of the socket portions 3 of adjacent fluorescent lighting fixtures are brought into contact with each other. Here, a small diameter part 3c is provided at the rear end of the outer case part 3a of the socket part 3, and a C-shaped elastic connection auxiliary spring 8 is elastically fitted into the adjacent small diameter part 3c for connection. It is something. In this case, socket part 3
I tried to install it so that the rear end surfaces were butted together, but due to an installation error, the socket part 3
A gap is created between the rear end surfaces, and in this case, the socket cover 4 must be strongly pushed in to remove the notch 5.
The socket cover 4 is made to protrude from the end surface of the socket part 3 by biting the back end into the rib 6 as shown in FIG. The ends of the socket cover 4 are brought into contact with each other so that no gap visible from the outside is created in this part.

[Effect of the invention] In the present invention, as described above, when the socket cover is fitted into the socket portion and the notch is fitted into the socket base, and the inner end of the notch is in contact with the rib, the end face of the socket cover on the notch side and The socket cover is set flush with the rear end surface of the socket, so when using a fluorescent lighting fixture alone, the socket cover can be fitted with normal force and the ribs can be used as positioning members to align the end of the socket cover. It is made of synthetic resin so that the socket and the end of the socket are flush with each other for a better appearance, and the rib is made of synthetic resin so that when the socket cover is pushed in forcefully, the inner end of the notch in the socket cover will not dig in or the rib will be scraped. Since the width is narrow, if there is a gap between the ends of adjacent socket covers when multiple fluorescent lighting fixtures are lined up in a straight line, push the socket cover firmly in so that the end of the notch digs into the rib. The socket cover can be made to protrude from the end of the socket part by cutting or cutting the ribs, and the ends of adjacent socket covers can be brought into contact with each other to prevent a gap from occurring in this part. Further, in order to prevent the occurrence of gaps as described above, it is sufficient to provide only narrow ribs made of synthetic resin, so that the structure is simplified.
