[Conventional technology]

For example, high brightness line-shaped tungsten-halogen lamps have already been used for outdoor lighting and other various types of lighting. A line-shaped tungsten halogen lamp is attached to a socket attached to a casing of a lighting device by being detachable and electrically connected thereto.

For example, as shown in FIGS. 1 and 2, a socket 1 attached to a casing of a lighting device has a head 2.
and relatively long leg portions 3. The head 2 has a U-shaped insertion groove 4 formed along the direction of the leg portion 3 from its upper end. The leg portion 3 is attached to the portion 6 by the lower end of the terminal plate 5 of a temporary spring type, and screws and the like are attached removably using a tool 7. A convex connection terminal 8 is provided on one surface of the upper end of the terminal plate 5 . Further, the line-shaped lamp 9 has connectors 11 electrically connected to the filament IO of the lamp 9 at both ends thereof.

The connector 11 is embedded in a flat portion 9a formed by compressing the end of the lamp 9 into a flat shape. Connector work 1 is ceramic 1
2 and is insulated from the outside.

The connector 11 is electrically connected within the ceramic 12 to a connector (not shown) having a connection recess 13 having a semicircular arc shape at the tip. The connection recess 13 is connected to the connection terminal 8.

A cut groove 14 is formed at the end of the ceramic 12 opposite to the connection recess 13 . The above-mentioned flat portion 9a is fitted into the notch a14, and is integrally connected with, for example, adhesive. Further, the eaves 2a of the head 2 are for making the connection between the connection terminal 8 and the connection recess 13 invisible from directly above the U-shaped opening for safety reasons. To attach the lamp to the socket configured as described above, insert the ceramic part 12 through the opening of the U-shaped insertion groove 4, and push the terminal plate 5 outward against the spring force. The connecting terminal 8 is engaged with the connecting recess 13.

Further, as shown in FIGS. 2 and 3, an insulating cylinder 20 is fitted and fixed to the cylindrical socket 1, and a recess 21 is formed in the insulating cylinder 20 along its axial direction. do. A connecting terminal 22 is slidably provided on the insulating cylinder 20. A stopper 23 is fixed to the inner end of this connecting terminal 22 and pressed against it by a spring 24. The open end of the socket 31 is connected to the insulating plate 2
Closes at 5. Therefore, the connection terminals 22 are in a state of being pushed outward in FIG. 4. Of course, in the case of this embodiment as well, if the connection recess 13 of the ceramic 12 of the lamp 9 is engaged against the acting force of the connection terminal 22 as in the previous embodiment, the electrical connection can be maintained. can be done. The connection terminal 22 is connected to a power source via a lead wire 26.

[Problem that the invention seeks to solve]

However, sockets equipped with a leaf spring type terminal block have a head part and a leg part, and have a structure in which a relatively long plate-shaped terminal board is attached, so it is inevitable that the connection terminal and the leg part are connected to each other. Since the distance rAJ between them increases, the socket itself becomes larger. Further, for example, if the ceramic is attached in a bent state to a flat portion formed at the end of the lamp, the lamp will be attached at an angle with respect to the socket, and the central axis of the lamp will not be horizontal. Therefore, the irradiation distance of the heat rays is not uniform throughout the axial direction of the lamp. Furthermore, since the ceramic is attached to the flat part using an adhesive, care must be taken to avoid bending the attachment part, which makes the attachment work cumbersome. Furthermore, in another type of device, since the connecting terminal is configured to be slidable by a spring, the length rAJ of the socket in the longitudinal direction becomes long, and the socket inevitably becomes larger as described above. Furthermore, since each of the above-mentioned devices has a structure in which the connection terminal is engaged with the connection recess against the spring force when the lamp is attached, the connection operation is relatively troublesome.

The present inventors have succeeded in developing a line-shaped lamp device that has a simplified structure and is free from poor contact.

That is, the present invention provides a simple structure in which the connecting terminals provided at both ends of the linear lamp in the longitudinal direction are formed into a flat shape, and the socket for receiving the connecting terminals is composed of a pair of connecting pieces facing each other. To provide a line-shaped lamp device that has a structure that allows a connection terminal to be simply dropped between a pair of connection pieces, facilitates the work of attaching and detaching the lamp, and that can be manufactured at a low cost and without failure. The purpose is to

The present invention further provides that when a linear lamp is installed in a socket, the connecting terminal and the connecting piece are connected by one-touch operation and surface contact, thereby making it possible to connect without contact failure and making the entire device compact. An object of the present invention is to provide a line-shaped lamp device configured as follows.

[Means for solving problems]

In order to solve the above-mentioned problems, the means of the present invention is such that both longitudinal ends of the linear lamp are removably fitted into a socket for attaching the lamp of a lighting device and are electrically connected. , which has connection terminals provided at both longitudinal ends of the lamp and connected to the filament of the lamp, and connection terminal elements having connection pieces facing each other and receiving these connection terminals. The lamp connection terminal is inserted into the upper end opening of the connection part of the connection terminal element in a drop-down manner, and the connection terminal and the connection part are connected by surface contact. This invention relates to a line-shaped lamp device.

[Effect]

The connecting pieces provided at both longitudinal ends of the lamp are inserted by dropping through the upper end opening of the connecting terminal element, and are positioned between the pair of connecting pieces and brought into surface contact with the connecting pieces. Then, the central axis of the lamp is forced to the horizontal axis of the lamp by the connecting terminal of the connecting terminal element and the connecting piece, and its centering can be easily performed, that is, the lamp is aligned over its entire axial direction. It becomes uniform with no slope. Furthermore, when removing the lamp from the socket, it is only necessary to remove the lamp straight, and therefore, the work of attaching and detaching the lamp is facilitated. Also,
Since the lamp is held in a straight line with respect to the socket, and the connecting terminal and the connecting piece are connected by surface contact, there is no contact failure.

The connecting terminal element 37 includes a body 40 having a pentagonal shape. A pair of connecting pieces 41 and 42 are formed continuously on this body 40 and stand up with a slight distance between them. The center portions of the connecting pieces 41, 42 are formed in an arc shape that bulges outward. The upper ends of the connecting pieces 41,42 are slightly bent outwards relative to each other. The inner surface of the bulge has convex connectors 43.4 facing each other.
4 is a provision. The lower chamber 35 has an L-shaped opening at the rear side (see FIG. 7). The corner portion of the opening is formed into an inverted letter-shaped notch 45.

A pivot 47 is passed through a through hole 46 provided at a corner of the socket body 31a, and a cover plate 48 is attached to the upper end of the pivot so as to be openable and closable. The notch 45 facilitates insertion of a fingertip when attaching or detaching the stopper screw 49 that fixes the lower end of the pivot 47. 50
is a spring that constantly pulls the pivot 47 downward to press the cover plate 48 against the opening surface. The purpose of this cover plate 48 is to prevent the connection between the lamp 30 and the connection terminal element 37 from being seen from the outside for safety reasons. lamp 3
0, as shown in FIGS. 5 and 11, both ends thereof are formed into flat parts 300.

A filament 301 of the lamp 30 is passed through the flat portion 300, and a connecting plate 302 is connected to the filament 301 of the lamp 30.

A U-shaped portion of a connecting terminal 303 having a convex tip is fitted onto the connecting plate 302, and electrically connected by, for example, spot welding. A pair of connecting pieces 304, 304 are provided continuous to the U-shaped portion and facing each other. These connecting pieces 304, 304 are slightly bulged outward at their center portions, and have contact holes 305 in the longitudinal direction.

However, the connecting pieces 304, 304 provided at both longitudinal ends of the lamp 30 need only be inserted in a drop-in manner through the upper end opening of the connecting piece 41, 42 of the connecting terminal element 37. This insertion causes the connection piece 304.
Connectors 43 and 44 are fitted into contact holes 305 and 305 of 304, respectively.

Therefore, the center axis of the lamp 30 can be easily centered by the surface contact engagement between the connector 43.44 of the connecting terminal element 37 and the contact hole 305.305 of the connecting piece 304.304. Lamp 30 is socket 3
1.32. In addition, their engagement is between the connector 43.44 and the contact hole 305.305.
Since the connection is made by surface contact at two places, a reliable connection without contact failure can be achieved.

In addition, in the above embodiment, the connecting holes are provided with oval shaped holes facing each other, but these connecting holes do not necessarily have to face each other, and may be formed by shifting their positions in the longitudinal direction, for example. good. Further, the connection hole may also be provided, for example, only on one side of the connection portion. Therefore, correspondingly, the connection terminal provided on the connection terminal element side may also have the same structure as the connection hole.

Further, as a modified example of the lamp 30, FIGS.
As shown in the figure. The lamp 301 in this embodiment differs from the lamps in the previous embodiments in its terminal structure. That is, the connection terminals 303, 303 provided at both ends of the linear lamp 301 in the longitudinal direction are formed into a flat shape. Of course, these connection terminals 303, 303 are electrically connected to the filament of the lamp 301, as in the previous embodiment. The socket 37 of the lamp 301 formed with such a terminal structure has a structure as shown in FIGS. 16 to 20.

The socket 37 shown in FIGS. 16 and 17 is formed by bending a single metal plate as explained in FIG. 9. However, in this structure, the tops of the bodies 40 are brought into close contact with each other, and the connecting pieces 41, 42 that are continuous therewith are close to each other. That is, when the connecting terminal 303 is simply inserted in a drop-in manner from the upper opening between the connecting pieces 41, 42, both surfaces of the flat connecting terminal 303 and the inner surface of the connecting piece 41, 42 are in surface contact with each other. It is characterized by its structure.

The socket 37 is removably fixed to the casing of the lighting device.

Furthermore, in the socket 37 shown in FIGS. 18 and 19, the structure of the connecting pieces 41, 42 differs slightly from the structure shown in FIG. 17. Forming from a single metal plate is the same as in each of the above embodiments.

However, in the case of this structure, the connecting pieces 41, 42 continuous with the body 40 are further folded inward in an inverted U-shape. The inner end of one of the connecting pieces 42 is bent into an L-shape, and its tip 420 is brought into contact with the inner end of the connecting piece 41, serving as a 17 pa. However, the connection terminal 30 is simply removed from the upper opening between the connection pieces 41, 42.
3 is inserted in a drop-in manner, both surfaces of the flat connecting terminal 303 and the inner surfaces of the connecting pieces 41 and 42 come into surface contact, and the bending piece 420 prevents the connecting terminal 303 from being pulled out.

Furthermore, the socket 37 shown in FIG. 20 is made by bending a single metal plate into an L shape and making a notch in one of the flange pieces. Then, the cut piece formed by the cut is bent so as to face the other web piece. Thus, the connecting pieces 41, 42 are formed by the web pieces and the flange pieces bent oppositely thereto. Further, the horizontal flange piece is removably fixed to the casing of the lighting device. However, when the connecting terminal 303 is simply inserted in a drop-in manner from the upper opening between the connecting pieces 41 and 42, the flat connecting terminal 30
3 are brought into surface contact with the inner surfaces of the connecting pieces 41 and 42, and the inner bottom surface of the connecting pieces 42 prevents them from being pulled out.
