Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a lamp base provided with a plurality of pilot lamps for displaying the electrical connection state of various electric members.

<Prior Art> Various pilot lamps have been proposed to display the electrical connection state of various electrical members. By the way, in order to know the connection state of a large number of electric circuits, a large number of pilot lamps connected to each electric circuit via resistors are required. For this reason, it is necessary to connect and fix each pilot lamp and the same number of resistors, respectively, so that the connecting work becomes troublesome and the mounting surface tends to be cluttered.

In addition, various pilot lamps having a structure in which a resin is injected into a case to hold a wire connection state of a required member and a terminal is projected have been proposed. There is a problem that the injection work is troublesome and that once the molding is performed, the replacement and maintenance of each member becomes impossible.

An object of the present invention is to provide a lamp assembly stand which allows a large number of pilot lamps and resistors to be arranged in a uniform row only by means of assembling each member, and which can be easily connected to an external circuit. It is what

<Means for Solving the Problems> The present invention is provided with a mounting seat for supporting a plurality of light emitting diodes vertically arranged with two input / output connecting rods from the lower part at the upper end, and one mounting surface on each side. A plurality of vertical insertion grooves into which one of the connecting rods of the light emitting diode is inserted are formed at regular intervals, and a plurality of mounting grooves for fitting resistors corresponding to each light emitting diode are formed at regular intervals on the other side surface. A connecting terminal is formed above the mounting groove, and an inserting groove into which the other connecting rod is inserted is formed. Further, the common terminal is laterally traversed in the row direction at the lower surface position of each mounting groove. A rectangular plate-shaped insulating mounting base is formed by connecting lateral grooves that are fitted to each other, and one side connecting end of the resistor fitted in each mounting groove is connected to the connecting rod. The connection end on the side is mounted in the lateral groove to contact the common terminal passed to the mounting base, From the lower surface, and a connecting foot rod which is inserted into the insertion groove of the light-emitting diodes,
A connecting rod formed at one end of the common terminal is projected, and further, the mounting base is covered with a case so that the light emitting diode is projected from an upper surface thereof. .

<Operation> One terminal of the light emitting diode is connected to the required circuit by the connecting rod, and the other terminal is also connected to the resistor by the connecting rod, and the other terminal of the resistor is common through the common terminal. Connected to the side. When the required circuit becomes conductive, the light emitting diode is electrically connected and emits light.

In this configuration, one connecting rod of each light emitting diode hangs down from the lower surface of the gathering stand, and the connecting rod of one common terminal projects out. Decrease significantly.

Further, in such a configuration, the light emitting diode is mounted on the mounting seat at the upper end of the mounting base, and the two input / output connecting rods are inserted into the vertical insertion grooves formed on both sides of the mounting base,
By assembling the resistor and the common terminal from the side surface of the mounting base, and further by depositing the case on the mounting base, resin injection or soldering can be omitted.

<Embodiment> An embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a rectangular plate-shaped insulative mounting base, which is made of an insulative resin material such as polycarbonate and has a protruding upper edge serving as a mounting seat 2 on which a plurality of light emitting diodes 10 are arranged.

Each of the light emitting diodes 1 is provided on one side of the mounting base 1.
A plurality of vertical insertion grooves 4 through which the connection rods 11a of 0 penetrate are formed at regular intervals.

Similarly, a plurality of mounting grooves 5 are formed on the other side surface at regular intervals corresponding to the respective light emitting diodes 10, and a connecting rod 11 hanging from the respective light emitting diodes 10 above the mounting grooves 5.
An insertion groove 6 through which b is inserted is formed. Further, on the other side surface, a lateral groove 7 that crosses the lower surface of each mounting groove 5 in a transfer manner.
Is formed, the common terminal plate 12 is inserted into the lateral groove 7, and the connecting rod 13 bent at one end thereof is inserted into the fitting groove 8 formed in the mounting base 1, It projects downward.

In such a configuration, the light emitting diode 10 is mounted on the mounting seat 2, the connecting foot rod 11a is inserted into the insertion groove 4, the lower end is projected downward from the mounting base 1, and the connecting foot rod 11b is further attached. Insert from the insertion groove 6 into the mounting groove 5 and bend.
Next, the resistor 15 is fitted into the mounting groove 5, the terminal on the upper surface is connected to the bent end of the connecting rod 11b, and the lower surface is pressed against the bulging portion 14 of the common terminal plate 12.

After the above-mentioned assembly, the case 20 having the lower surface opened and the upper surface formed with the holes 21 through which the respective light-emitting diodes 10 can be projected is externally fitted onto the mounting base 1 from above. And
From the hole 21 on the upper surface of the case 20 to the light emitting diode 1
Expose 0.

In such a configuration, since only the connecting rods 11a and the connecting rods 13 project on the lower surface of the lamp base, by fitting this into the required through holes of the printed circuit board,
Connections with the required conductive paths are made. Then, as shown in FIG. 4, the aligning circuit 30 of the light emitting diodes 10 connected to the common terminal side by the connecting rods 13 is configured, and the required electric power of the IC package connected to each connecting rod 11a side is formed. It is possible to detect the open / closed state of the circuit by blinking each light emitting diode 10.

The connection direction of the light emitting diode 10 may be either forward or reverse depending on the relationship with the power source side.

<Effects of the Invention> As is apparent from the above description, the present invention does not require the light emitting diodes 10 to be arranged in a row and to connect each light emitting diode 10 and the resistor 15 by a conductive path on the printed circuit board. Therefore, it is possible to design a well-coordinated circuit.

Further, since fixing to the printed circuit board or the like is required only by fixing the lower surface of the mounting base 1, it is easy to install and fix. Further, since one end side of the light emitting diode 10 is shared by the common terminal plate 12, only the connecting rod 11a and the connecting rod 13 project from the lower surface of the mounting base 1, and the number of projecting pieces is small and electrical connection is made. Is easy.

Furthermore, the light emitting diode 10 is mounted on the mounting seat 2 at the upper end of the mounting base 1, and the two input / output connecting rods 11a,
11b are inserted into the vertical insertion grooves 4 and 6 formed on both sides of the mounting base 1, the resistor 15 and the common terminal 12 are assembled from the side surface of the mounting base 1, and the case 2 is covered from above the mounting base 1. It can be assembled by wearing, and therefore, soldering and resin injection are not required, and the manufacturing is facilitated, and the light emitting diode 10 and the resistor 15 are also provided.
In the event of damage or failure, the parts can be easily replaced and maintenance management is simplified, which is an excellent effect.
