Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an indicator light, and particularly to a novel configuration that allows the indicator light to be used both in combination with a transformer and without a transformer.

In general, indicator lights include so-called full-voltage indicator lights, which are used by being directly connected to a power source, and indicator lights with a transformer, which are used by reducing the voltage through a transformer.

The former is used as a low-voltage power supply whose power supply voltage matches the lamp rating of the indicator light, and the latter is used by being connected to a normal commercial or industrial power supply, so the two have different configurations. This invention provides the above-mentioned completely different indicator light,
This invention is designed so that one indicator light can be used for both purposes, and the present invention will be described in detail below with reference to an illustrative embodiment.

In the figure, 1 is a cylindrical front part, a box-shaped rear part, and has a through hole in the center. 2 and 3 are the main body 1.
A panel mounting thickness adjustment ring and a bezel are attached to the cylindrical portion of the panel, and 4 is a cap made of a transparent member. 5
is a lamp having a plug-in base 51 with a pin.

Reference numeral 6 denotes a first lamp holder member, in which a lamp holder 62 for holding the lamp 5 is erected from one end of the inner side of a base 61 formed of a conductive material, and a lamp holder 62 for holding the lamp 5 is provided at the corner of the outer side of the base 61. A mounting portion 63 is formed with a female thread for screwing and mounting the terminal screw 10 thereon.

Further, a tongue piece 64 is made to protrude from the base 61 at the lower corresponding part of the lamp receiving part 62, and a plug part 81 provided on a lead-out fitting 8 formed of a conductive plate material different from the receiving part member 6 is directed downward. In this way, the lead-out metal fitting 8 is integrally attached to the tongue piece 64.
T is a second lamp holder member, which forms a mounting part 72 with an internal thread for screwing the terminal screw 10 into the corner of the outer part of the base Ti formed of a conductive material, and also has a mounting part 72 on the inner part. A tongue piece 73 is made to protrude from one end, and a lead-out metal fitting 9 formed of a conductive plate material different from the receiving member 7 is integrally attached to the tongue piece 73. The lead-out fitting 9 has a downwardly extending receiving part 91 formed on one side thereof, and a lamp receiving plate 92 is erected upwardly inward from approximately the center. Furthermore, 65
and 74 are positioning holes formed on each of the bases 61 and 74, which are fitted into protrusions (not shown) formed in advance inside the box-shaped interior of the indicator light body 1, and the receiving members 6 and 7 are inserted into the holes. It is positioned at a predetermined portion of the indicator light body 1. This invention is characterized in that an indicator light is constructed using the above-mentioned receiving members 6 and 7. That is, as shown in FIG. 2, the bases 61 and 71 of the receiving members 6 and 7 are disposed at a predetermined box-shaped rear part of the indicator lamp body 1, with the inner sides of the bases 61 and 71 facing each other. Then, in the state after installation, the tip of the lamp receiving plate 92 is positioned corresponding to the cylindrical inner middle part of the lamp holder 62 to form a lamp receiving portion. Therefore, when the lamp 5 is fitted to the lamp holder 62 via the pin-attached socket-type base 51, the lamp 5 is attached to the socket-type base 51 and the lamp holder 62.
A contact state is maintained between the lamp lead-out end portion 52 and the lamp receiving plate 92. Further, the mounting parts 63 and 72 to which the terminal screws 10 and 10 are mounted are located at obliquely opposing parts on the back surface of the box shape, as shown in FIG. Ru.

Further, the other receiving plug portions 81 and 91 are located at approximately the center of the box shape and have window holes 11a and 1 formed in the lid body 11 that covers the back surface of the box shape.
It is exposed to the outside through 1a. 12 is an example of a transformer used in the present invention, which includes engaging pieces 13, 13 erected upward from both sides of the upper surface of the transformer body, and secondary terminals 14, 14 of the transformer protruding upward from approximately the center of the upper surface. The primary terminals 15, 15 of the transformer are provided on both sides of the lower side of the main body.

In the indicator light having such a configuration, when the indicator light is used for full voltage, wire holding fittings 16, 1 are connected to the terminal screws 10, 10 exposed on the rear box-shaped back surface of the main body 1.
A lead-in wire is directly attached from the low-voltage power supply through the 6.

When used as an indicator light with a transformer, the engaging pieces 13, 13 of the transformer 12 are engaged with the stepped portions 1a, 1a formed on both lateral outer walls of the indicator light body 1. At the same time as the transformer 12 is mechanically coupled to the
The transformer 12 and the receiving members 6, 7 in the indicator lamp body 1 are electrically connected by inserting the next terminals 14, 14 into the sockets 81, 91 facing the window holes 11a, 11a. .
Note that the plug portions 81 and 91 are not necessarily limited to the shape of the embodiment, and for example, the plug portions 81 and 91 may be shaped like plage terminals to form the secondary terminals 14 and 14 of the transformer 12.
may be shaped like a socket terminal. According to the present invention, as explained above, the first lamp holder member 6 and the second
Since the lamp holder member 7 is formed with mounting parts 63, 72 for screwing the valley terminal screws 10, 10 and plug parts 81, 91 to which the terminals 14, 14 of the transformer 12 can be detachably attached, A single indicator light can be used as either a full-voltage indicator light or a transformer-equipped indicator light, improving the versatility of the indicator light, while reducing the number of parts and assembly man-hours compared to conventional indicators. It produces a special effect that is no different from a light.
