Abstract

PURPOSE:To reduce the number of parts and the power consumption by providing an illumination lamp in a plug-side connector with a cable or an adapter attached to this connector to illuminate an operation panel surface with one illumination lamp. CONSTITUTION:A plug-side connector 11 with a cable 10 is provided with an illumination lamp 14 such as a lamp, a light emitting diode, or the like whose projection window 13 is directed to the surface of an operation panel 2. A power source is connected to the illumination lamp 14 through connectors 8 and 11. Though a switch 15 for illumination which is inserted to a power supply circuit of the illumination lamp 14 is provided in the plug-side connector 11, this switch 15 can be omitted. If the switch 15 for illumination is not provided, the illumination lamp 14 is lit when a power switch of a radio machine 1 is turned on; and if the switch 15 for illumination is provided, the switch 15 for illumination is turned on to light the illumination lamp 14 when it is necessary to illuminate the peripheral part darkly, and the overall surface of the operation panel 2 is illuminated by lighting of the illumination lamp 14.

Description

[Detailed Description of the Invention] [Industrial Application Field] Generally, radio equipment is mounted on automobiles, airplanes, and work trolleys that travel in tunnels, or installed in tunnels, underground passages, tents, or outdoors. Radio equipment, measuring equipment,
Control equipment and the like are equipped with lighting lights for use at night or in darkness.

The present invention relates to personal radio equipment, amateur radio equipment, and commercial radio equipment in which electronic components such as a transmitter, handset, various devices, or other electronic devices are connected to a receptacle connector of an operation panel by a plug connector with a cable. The present invention relates to radio equipment such as radio equipment, measuring equipment, control equipment, etc. (hereinafter collectively referred to as electronic equipment), and particularly relates to the illumination structure of the operation panel surface thereof.

[Prior art]

First, illumination by conventional illumination lights will be specifically explained using an automobile radio device as an example.

FIG. 1 is an external perspective view showing an example of a conventional automobile radio device. 1 is a radio device installed at the bottom of the dash board of a car so that it can be easily operated by the driver, 2 is its operation panel, and 3 is a push button for a push button switch.
It is made of a semi-transparent material and is configured so that its location can be determined by illuminating it from the back side with a lighting lamp. 4 is a display window that displays information such as characters. It is made of a transparent material and can be seen from the side. The structure is such that the information can be read by illuminating it with lighting. Reference numeral 5 designates a rotary knob, which is illuminated by an illumination light from the back side of an illumination plate 7 provided in a gap 6 between the rotary knob 5 and the operation panel 2, so that its position can be determined. Reference numeral 8 denotes a receptacle-side connector attached to the operation panel 2, and as shown in the second figure, a handset or handset 9 is connected by a plug-side connector 11 with a cable IO.

In this way, conventionally, in order to illuminate operating parts such as the push button 3 and rotary knob 5, and the display window 4, it is necessary to provide a lighting lamp for each part 4J, and some models also include a lighting board. Not only does it have a large number of parts and consume a lot of power, but it also has the disadvantage of spoiling its appearance because the parts are made of materials that can transmit light.

In the case of a car radio, the interior light can be turned on to illuminate the operation panel surface, but if there are no passengers and the driver is the only one, the driver can extend one hand and turn on the interior light on the ceiling. In addition, because the interior light on the ceiling is far from the operation panel of the radio installed near the dash board, the interior light cannot illuminate the operation panel sufficiently. Sometimes you can't see it.

[Purpose of the invention]

The present invention aims to improve the above-mentioned drawbacks.

[Structure of the invention]

To achieve the above object, the present invention provides an electronic device in which an electrical component or other electronic device is connected to a receptacle side connector 8 of an operation panel 2 by a plug side connector 11 with a cable 10, as shown in the drawings. An illumination lamp 14 with a light projection window 13 facing the operation panel 2 is provided on an adapter 12 attached to the side connector 11 or the plug side connector 11 with a cable 10.

[Configuration of Example]

The present invention will be explained in detail below with reference to the drawings.

Figure 2 shows the first example when the present invention is applied to an automobile radio device.
It is an external perspective view showing an example.

In the first embodiment, a plug-side connector 11 with a cable 10 is provided.
An illumination light 14 such as a lamp or a light emitting diode is provided with a light projection window 13 facing the two surfaces of the operation panel. Of course, the power source is connected to the illuminating lamp 14 via the connectors 8 and 11. Note that 15 is a lighting switch inserted into the power supply circuit of the illumination lamp 14, and is provided on the plug side connector 11, but this lighting switch 15 may not be provided.

FIG. 3 is an external perspective view showing the main parts of the second embodiment.

In the second example h1'x, an adapter 12 is attached to the plug side connector 11 with cable 10, and this adapter 12 is
An illumination light 14 with a light projection window 13 facing the two sides of the operation panel is provided. In this case, the lighting switch 15 is provided on the adapter 2.

In either embodiment, the plug side connector 11 is inserted into the receptacle side connector 8 so that the groove 11B of the plug side connector 11 fits into the protrusion 8a of the receptacle side connector 8, and the circular nut U of the plug side connector 11 is inserted.
b is screwed onto the outer circumferential screw 8bK of the receptacle side connector 8 to fix it.

[Effect of the embodiment]

Since the present invention has the above-described configuration, when the lighting switch 15 is not provided, the lighting lamp 14 is turned on when the power switch (not shown) is turned on, and the lighting switch 15 is provided. When the surroundings are dark and illumination is required, the illumination switch 15 is turned on to turn on the illumination light 14, and the entire surface of the operation panel 2 can be illuminated by turning on the illumination light 140.

Since the radio device 1 is installed at the bottom of the dash board so that the driver can easily operate it while driving, operating the lighting switch 15 is also easier than turning on the interior light on the ceiling. There is no risk of interfering with safe driving.

Note that the present invention is not limited to a single automobile radio device, but can also be applied to an airplane,
Radio equipment mounted on a work trolley running inside a tunnel,
Alternatively, radio equipment installed in tunnels, underground passages, inside tents, or outdoors, and furthermore, gas detection sensors, heat detection sensors, etc. can be connected with connectors, electronic devices such as voice measurement devices, sensors, or control devices. It can be widely applied to electronic devices etc. connected with connectors. Incidentally, the above-mentioned lighting switch can also be provided on the telephone receiver, transmitter/receiver bar, ξ device 9, or operation panel 2.

〔effect〕

As described above, according to the present invention, the plug with cable ff
Since the light is provided on the 111 connector or the adapter attached to the connector, the operation panel surface can be illuminated with a single light, reducing the number of parts and consumption.
It is not a fool's errand to reduce the force, and it can be implemented at low cost without damaging the appearance or complicating the structure. Further, when applied to an on-vehicle radio, there is no risk of interfering with driving, so safety can be ensured.

When using an adapter for river use, use a commercially available connector11
It can be implemented at different times.
