Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a gauge assembly erroneous assembly prevention structure for a combination meter in which various gauge assemblies with relay plates are assembled in a case.

[Conventional technology]

Speedometers, tachometers, instruments used in vehicles, etc.
There are various instruments such as a fuel gauge, and a combination meter in which these instruments are put together in one case is widely used. In order to assemble the combination meter, these various instruments are first assembled as a gauge assembly, and as shown in FIG. In addition, an opaque veneer 52 such as black is attached to the peripheral edge of the case 51 to cover the end edge of the dial plate 53 of the gauge assembly 50, and a transparent front plate (not shown) covers it. Has been completed.

However, some gauge assemblies, such as a speedometer and tachometer, or a fuel gauge and a thermometer, have similar external shapes due to manufacturing cost or design considerations, which may cause errors during assembly. There is a risk that different types will be assembled.

Therefore, conventionally, for each type of gauge assembly 50, holes 54 are provided at different positions in the dial plate 53 of the gauge assembly 50 where they are hidden by the dial 52, and are provided in the dial plate 53 of each gauge assembly 50 of the case 51. The pins 55 which are inserted / fitted into the holes 54 are provided upright at positions corresponding to the holes 54 to prevent erroneous assembly.

[Problems to be solved by the device]

However, since the above-mentioned structure for preventing misassembly is provided with a hole in a part of the dial plate of the gauge assembly which is concealed by the dial so that the pin erected on the case can be fitted, the gap between the dial and the dial is reduced. Since it is narrow, it is not possible to increase the size of the pin protruding from the hole of the fitting portion.
Therefore, as shown in FIG. 6, even if another gauge assembly 60, which should not be mounted at that position, is attached, the dial plate in the state where the pin 55 of the case is not fitted into the hole provided in the dial plate 63 is installed. Since there was little uplifting, there was a case that the wrong assembly was done without noticing.

Therefore, an object of the present invention is to provide a structure for preventing misassembly of a gauge assembly of a combination meter, which prevents misassembly when the gauge assembly is assembled to the combination meter.

[Means for solving the problem]

The present invention is a combination meter in which various gauge assemblies with relay plates are assembled in a case, and holes are provided at different positions of the relay plate for each kind of the gauge assembly, and It is characterized in that pins that pass through the holes are erected at positions corresponding to the holes provided in the relay plate of the gauge assembly to prevent erroneous assembly.

[Action]

Based on the above configuration, when assembling various gauge assemblies in the combination meter case, if you try to place the gauge assembly at the wrong position, the pins installed on the case and the relay plate of the gauge assembly will be installed. The gauge assembly cannot be placed in the case because of the misalignment with the holes provided, which prevents erroneous assembly.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows, as an embodiment, a combination meter 1 in which a fuel type assembly 2 is arranged on the left side of a case 20 and a thermometer assembly 3 is arranged on the right side. As shown in FIG. 2 in a side view, the fuel type assembly 2 is provided with a relay plate 14 that relays a signal from a sensor installed in a fuel tank (not shown).
An internal machine 13 for driving the pointer 11 is attached to the. Further, a dial 12 on which characters, scales and the like indicating the amount of fuel are written is sandwiched between the inner unit 13 and the pointer 11, and the dial 12 is screwed to the inner unit. Further, the relay plate 14 is provided with a hole 14a having a thread groove and a positioning hole 14b having no thread groove, and the hole 14a is for fixing the fuel type assembly 2 to the case 20.

On the other hand, the thermometer assembly 3 also has substantially the same outer shape as that of the fuel type assembly 2 described above, and as shown in FIG. 1, there is a screw groove provided on the relay plate 16 for fixing the assembly 3. The position of the hole 16a is the same as that of the fuel type assembly 2 described above, but the position of the positioning hole 16b having no thread groove is different.

On the other hand, as shown in FIG. 1, the case 20 has a box-like shape having a substantially rectangular shape in a front view, and arms 22 and 23 project vertically, and the case 20 uses these arms 22 and 23 for a vehicle or the like. The structure is fixed to the instrument panel of.

Further, three holes 24 are provided at each of the positions on the rear surface of the case 20 where the fuel gauge assembly 2 and the thermometer assembly 3 are arranged, and as shown in FIG. 3, the fuel gauge assembly 2 is relayed. Positioning hole in plate 14
Pin 21 at the position corresponding to 14b, thermometer assembly 3
Pins are similarly provided upright at positions corresponding to the positioning holes 16b of the relay plate 16.

Then, when the fuel type assembly 2 is assembled to the case 20, as shown in FIGS. 3 and 4 (b), the pin 21 is inserted / fitted into the positioning hole 14b provided in the relay plate 14. To do. Similarly, in the thermometer assembly 3, the corresponding pin provided in the case 20 is inserted and fitted into the positioning hole 16b provided in the relay plate 16. Then, as shown in FIG. 3, holes formed in the rear surface of the case 20.
Each assembly is positioned and fixed by inserting a screw 25 from 24 and engaging with the holes 14a, 16a provided in the relay plates 14, 16.

Therefore, even if the fuel gauge assembly 2 and the thermometer assembly 3 are confused and the thermometer assembly 3 is mounted on the left side of the case 20 shown in FIG.
The pin 14b erected on 20 and the positioning hole 16b provided with the relay plate are not aligned, so that the thermometer assembly 3 cannot be assembled with a large inclination as shown in FIG. 4 (a). . On the contrary, even if the fuel gauge assembly 2 is to be assembled on the right side of the case 20 shown in FIG. 1, it cannot be assembled in the same manner. Therefore, erroneous assembly of each gauge assembly into the case 20 can be completely prevented. Further, as in the conventional case, it is not necessary to make holes at different positions of the dial plates of the respective gauge assemblies to distinguish them from each other or to make the dial plates different in shape as in the conventional case. Since the shape of the dial plate of 3 in total can be made common, the cost of the mold can be reduced.

Although the fuel gauge assembly 2 and the thermometer assembly 3 are used as the gauge assembly to be assembled in the combination meter in this embodiment, a combination of a speedometer and a tachometer may be used, or several kinds of gauge assemblies may be combined. It may be one.

[Effect of device]

As described above, according to the present invention, in the combination meter in which various gauge assemblies with relay plates are assembled in the case, holes are formed at different positions of the relay plate for each kind of the gauge assembly. Since the pins that pass through the holes are provided at the positions corresponding to the holes provided in the relay plate of each gauge assembly of the case, the misassembly of the gauge assembly to the case of the combination meter is prevented. Can be planned.
