Description

[Detailed Description of the Invention] This invention relates to an indicator light with a resistor used, for example, in a switchboard or the like.

Figure 1 shows a conventional example of this type of indicator light. In the figure, 1 is a case, 2 is a glove removably provided at the upper end of the case 1, 3 is a tightening ring, and 4 is a neon lamp housed in the case. 5 is a base, 6 is a receiver, 7 is an insulating stand, 8 is a cylindrical resistor, and 9 is an external terminal.

Resistors conventionally used in this type of indicator light are generally cylindrical or columnar. Fixedly attached.

In other conventional methods, a cylindrical resistor is attached in the middle of the lead wire.

Since a cylindrical resistor is used, it is difficult to incorporate both a series resistor and a parallel resistor into a single unit, and the built-in resistor type has the disadvantage that it is difficult to incorporate a parallel resistor to prevent false lighting. Ta.

In addition, in the case where the resistor is fixedly attached, the dimensional accuracy of the resistor is required, and when the external terminal is moved, abnormal force is applied to the connection part, so the terminal part must be firmly fixed. Ta.

This invention aims to improve the above-mentioned drawbacks.

FIG. 2 is an exploded view showing an embodiment of this invention.

FIG. 3 is a partial assembly diagram of the resistor, and FIG. 4 is a resistor circuit diagram.

In Figure 2, 10 is a series resistor R for lighting the neon lamp.
1 and a parallel resistance hole R2 for preventing erroneous lighting on the same substrate.It is inserted into a recess 16 provided in an indicator light case 14, which will be described later, and has an opening on one side.
6 is supported.

IOA, 10B, IOC is the 4th flexible lead wire.
The circuit configuration is as shown in the figure.

11 is a tab terminal for a plug-in terminal, 5 is a cap, and 13 is a tab terminal for a plug-in terminal that also serves as a light bulb holder.

14 is an indicator light case, and 15 is a lid shaped like a cylinder divided into two in the axial direction.

In the indicator lamp constructed as described above, the resistors R1 and R2 are made of raw material in the resistor 10, so that the two resistors can be easily and compactly incorporated.

Also, the flexible lead wire 10A coming out from the resistor 10, IO
B and 10C are tab terminals 119 and caps 5 fixed between the indicator light case 14 and the lid 15;
The resistor 10 is connected to the tab terminal 13, and the resistor 10 is connected to a predetermined fixed space provided in the indicator light case 14, that is, the recess 1
Built in 6.

For this reason, tab terminal 1 due to the operation of inserting one line from the outside.
The fluctuation of 1.13 is absorbed by the lead wire 10A, IOC,
The structure is such that no abnormal force is applied to the resistor 10.

The tab terminals 11, 13 may be fixed even if there is play, and the tab terminal support structure can be made very simple.

Furthermore, since the resistor 10 is inserted and supported in the recess 16, the dimensions between the resistor 10, the tab terminal 11, the cap 5, and the tab terminal 13 can be adjusted when assembled into the indicator light case 14. As shown in FIG. 3, the resistor 10, tab terminal 11, base 5, and tab terminal 13 can be connected separately and then assembled into the indicator lamp case 14, making assembly very easy.

With the above-described structure, this invention has the advantage that a resistor for preventing erroneous lighting can be compactly built in, and the indicator lamp can be easily assembled.
