(d) Means for solving the problem The above objectives are achieved by connecting and assembling the cluster indicator lights using a connecting member that can connect the indicator lights with one touch, and by equipping the connecting member with a light blocking function. Therefore, the collective indicator light of the present invention has a plurality of indicator lights arranged closely together and connected together by engaging connecting members at each adjacent corner of the indicator lights, and To the above connecting member,
The present invention is characterized in that a light shielding portion is formed to close the gap between the connected indicator lights and block light leakage from the gap. Further, it is preferable that the tips of the light shielding parts have elasticity, and the tips of adjacent light shielding parts are arranged so as to press into close contact with each other.

(e) Effect If a plurality of indicator lights are placed close together and a connecting member is inserted from the back side into each adjacent corner of the indicator lamp, the connecting member will be fixed to the indicator lamp, and the light-shielding part of the connecting member will be fixed. The plurality of indicator lights are connected and assembled together to form a collective indicator light, with the gaps between the indicator lights being closed.

(f) Embodiment An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a schematic perspective view of a gathering indicator light according to an embodiment of the present invention.
For example, a case 3 in the shape of a rectangular parallelepiped with an open front and a flange 2 formed on the front periphery.
A light source (not shown) such as an LED is stored, and a display plate 4 is attached to cover the opening on the front side of the case 3 to form an indicator light 5. A gap 6 having a dimension approximately twice the width of the flange portion 2 is formed between the two, and a connecting member 7 is attached to each of four adjacent corners on the rear side of the indicator light 5 to form a plurality of indicator lights. It has a structure in which 5 are connected and set together. Note that 8 is a mounting member made of an elastic material for mounting the collective indicator light 5 on a mounted part such as a panel of an instrumentation panel, and 9 is an external lead for supplying power to the light source.

The case 3 of the indicator light 5 is made of reinforced plastic such as glass fiber-filled polycarbonate, and has rectangular engagement holes 1 in each square on the back surface.
0a and a round guide hole 10b.
is drilled.

The connecting member 7 is made of reinforced plastic similar to the case 3, and as shown in FIG.
An engaging part 11 consisting of four engaging claws 11a that engage with the engaging hole 10a of the engaging part 10 of the case 3 and four guide pins 11b that are fitted into the guide holes 10b of the engaging part 10. and a cross-shaped protrusion 12 inserted into the gap 6 on the back side between adjacent cases 3.
is installed protrudingly. The guide pin 11b has a tapered shape, and the outer diameter of its root portion is approximately the same as the inner diameter of the guide hole 10b.

The connecting member 7 also includes a connected indicator light 5.
A gap 6 formed on the back side between the two and a slight gap 13 continuous with the gap 6 and created between the flange parts 2.
A light shielding portion 14 is formed at the tip of each of the cross-shaped projections 12 in order to shield light leaking through the cross-shaped projections 12. The light shielding portion 14 has a dimension larger than the width of the gap 6, and its tip portion 14a is formed into a thin plate shape to provide elasticity. The connecting member 7 is provided with a hole 16 for attaching a reinforcing member 15 at approximately the center of its back surface in order to supplement the connecting strength when a large number of indicator lights 5 are connected.

However, as shown in FIGS. 2A and 2B,
A plurality of indicator lights 5 are arranged so that the flange portions 2 formed on the front surface of the case 3 are brought into close contact with each other, and a gap 6 is formed on the back side.
If the connecting member 7 is brought into contact with each adjacent corner of the indicator light 5 from the back side and pressed, the guide pin of the engaging portion 11 formed on the connecting member 7 will first be released. 11b enters into the guide hole 10b of the engaging part 10 formed in the case 3 and is positioned, and then the engaging claw 11a of the engaging part 11 and the projection part 12 of the connecting member 7 are respectively inserted into the engaging part 10 of the case 3. It is inserted into the matching hole 10a and the gap 6 on the back side between the case 3. Furthermore, the guide pin 11b is fitted with its root portion pressing against the inner wall of the guide hole 10b,
The engagement claw 11a is inserted through the engagement hole 10a and its tip engages with the inner surface of the bottom of the case 3, and the protrusion 12 is held in the gap 6 between the cases 3 on the back side. Thus, a plurality of indicator lights 5 are connected and aggregated to form a collective indicator light 1. In this case, the light shielding part 14 of the connecting member 7
is closed, and the adjacent tips 14a are brought into close contact with each other due to elasticity, and the gap 6 is completely closed. In addition, when the number of indicator lights 5 to be connected is very large, as shown in FIG. Since it can be attached, the connection strength of the group display etc. 1 can be reinforced. In addition, when configuring the indicator light 1, if it is necessary to attach the connecting member 7 to the outermost corner of the indicator light 5 arranged at the peripheral end, the connecting member 7 can be attached to the protrusion 12. A connecting member having a shape cut in half may be used.

(g) Effects of the invention As detailed above, the assembly indicator light of the present invention is equipped with a connecting member that can connect multiple indicator lights with one touch, so the assembly work is easy.
In addition, since the screen configuration can be easily and freely changed, changes in specifications can be dealt with quickly, and the connecting member can be manufactured at low cost, so it has excellent economic efficiency. Furthermore, since the connecting member is provided with a light shielding portion that closes the gap between the indicator lights on the back side, there is no risk of light leakage from the gap, and display performance is improved.
