Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a fluorescent lamp device consisting of a fluorescent lamp and a fluorescent lamp socket, and more particularly, to a fluorescent lamp device that securely connects a fluorescent lamp and a fluorescent lamp socket of a fluorescent lamp device. It concerns the improvement of means.

(Prior Art) Fluorescent lamps are currently in practical use with various lengths, thicknesses, and shapes depending on their uses. In most of these fluorescent lamps, a cap pin embedded in a roughly cylindrical cap provided at the end is inserted into the fluorescent lamp socket and brought into contact with a pin contact fitting provided inside the socket to connect the fluorescent lamp and the socket. By electrically connecting the fluorescent lamp and the socket, and inserting the base pin into the socket, the fluorescent lamp and the socket are held in a joined state.

In addition, when arranging multiple long fluorescent lamps in the same straight line, make sure that the socket and the fluorescent lamp are perpendicular to the axial direction of the cap to avoid large gaps between the fluorescent lamps. It is desirable to engage from this direction. In such a case,
A cap pin is protruded in the radial direction on the circumferential surface of the cap, and the socket is mounted relative to the fluorescent lamp in a direction perpendicular to the axial direction of the cap.

However, in the above-described fluorescent lamp device in which a fluorescent lamp and a fluorescent lamp socket are joined in a direction perpendicular to the axial direction, the fluorescent lamp and socket are joined and held only by inserting the base pin into the socket. Because of this, the fluorescent lamp base pins tend to be inserted incompletely into the sockets, and even after insertion, when a force in the opposite direction to the insertion direction is applied to the device, the contacts may loosen or break. There were problems such as parts falling off and poor electrical contact between the fluorescent lamp and the socket, resulting in heat generation and burnout.

(Purpose of the invention) The present invention has been made in view of the above-mentioned problems.
It is an object of the present invention to provide a fluorescent lamp device that can be held securely and used safely without generating heat or burning out.

(Structure of the device) As described above, the cylindrical cap of the present invention has a cap pin protruding on the circumferential surface, and has a fitting recess extending in the axial direction on the circumferential surface, and the fluorescent lamp socket is The device is characterized in that it integrally includes a pair of elastic supports having a fitting convex portion that engages with the fitting recess and extending in the circumferential direction along the circumferential surface of the cap. The elastic support is adapted to support the cap while engaging the fitting protrusion with the fitting recess of the cap, and its size, shape, etc. are such that the fluorescent lamp and the fluorescent lamp socket can be reliably joined. In addition, when removing the fluorescent lamp from the socket, the setting may be such that the fluorescent lamp and the socket can be joined with a strength that allows removal relatively easily.

(Example) Hereinafter, a fluorescent lamp device of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the structure of the main parts of a fluorescent lamp and a fluorescent lamp socket according to an embodiment of the present invention.

A substantially cylindrical cap 2 is provided at the end of the cylindrical fluorescent lamp 1, and the circumferential surface of the cap 2 has two grooves extending in the radial direction of the cap, which is a direction perpendicular to the longitudinal direction of the fluorescent lamp 1. The book cap pin 3 is being talked about. Furthermore, the cap pin 3 is provided on the circumferential surface of the cap 2.
Two fitting recesses 4 are provided substantially perpendicularly to each other at positions facing each other. On the other hand, a fluorescent lamp socket 5 that engages with the base pin 3 and electrically connects to the fluorescent lamp 1 is provided with two insertion holes 6 into which the base pin 3 is inserted, and is electrically connected to an external power source by a lead wire 7. It is connected to the. Further, the fluorescent lamp socket 5 is provided with a pair of elastic supports 8 which are elastic members made of polycarbonate or the like. The elastic supports 8 are provided so as to support the circumferential surface of the cap 2 when the cap pin 3 of the fluorescent lamp 1 is inserted into the insertion hole 6 of the fluorescent lamp socket 5, and each It has a fitting protrusion that engages with the fitting recess. FIG. 2 is a side view showing the above fluorescent lamp and fluorescent lamp socket joined together, and FIG. 3 is a front view thereof.

As shown in FIGS. 2 and 3, in the fluorescent lamp and fluorescent lamp socket according to the present invention, the cap pin 3 is inserted into the insertion hole 6 to electrically connect the cap 2, and the cap 2 has the fitting recess 4. Since the elastic support 8 having the fitting convex portion 9 is designed to support the fluorescent lamp and the fluorescent lamp socket, some force is applied to the fluorescent lamp and the fluorescent lamp socket in the direction of disconnecting the two (in the vertical direction in Figs. 2 and 3). Even if the contact is easily loosened, as in the conventional fluorescent lamp device shown in FIGS. 4 and 5,
It will never come off. Furthermore, when removing the fluorescent lamp from the fluorescent lamp socket, the elastic support 8 can be removed easily because it has elasticity, and there is no risk of damaging the parts.
The fluorescent lamp and the socket can be reliably joined together without sacrificing good attachment/detachability. Therefore, by arranging a plurality of fluorescent lamps in series as shown in FIG. 2, the non-illuminated areas between adjacent fluorescent lamps are minimized, and the plurality of fluorescent lamps provide substantially continuous illumination in a linear manner. be able to. Although the fluorescent lamp device of the above embodiment uses a fluorescent lamp having two base pins, any number of base pins may be used.

(Effects of the Invention) As explained above, according to the fluorescent lamp device of the present invention, the base of the fluorescent lamp having the fitting recess is supported by the elastic support having the fitting protrusion that engages with the fitting recess. This prevents the connection from loosening or coming off easily even if some force is applied to the fluorescent lamp and fluorescent lamp socket, ensuring safety by preventing electrical contact failures that may cause heat generation or burnout. In particular, the safety of a fluorescent lamp device having a removable socket, which is susceptible to poor contact, is greatly improved.
