Description

  The present invention relates to a cable support structure for supporting a cable for supplying electric power to a discharge lamp such as a fluorescent lamp provided in a housing of an amusement machine or an exhibition stand, for example, an illumination device, and a method for manufacturing the illumination device.

  2. Description of the Related Art Conventionally, for example, lighting devices are provided in a housing of a gaming machine such as a pachinko machine or a slot machine, or in an exhibition case. In this type of lighting device, a cold cathode fluorescent tube, which is a straight tube fluorescent lamp that is relatively smaller than a general fluorescent lamp, is used as a lamp.

  As such a conventional lighting device, a configuration including a lamp cover for protecting a cold cathode fluorescent tube that is relatively easily damaged and an inverter power supply unit attached to the lamp cover is disclosed (for example, Patent Documents). 1).

And in the conventional illuminating device using this kind of cold cathode fluorescent tube, one end of two cables for supplying electric power from the inverter power supply unit is soldered to both ends of the circuit board of the inverter power supply unit, respectively. And the other end of each cable is electrically connected to the lamp connector at each end of the cold cathode fluorescent tube.
JP 2003-132730 A

  By the way, in the conventional illuminating device mentioned above, there existed a problem that the soldering operation | work of two cables was complicated and productivity was scarce.

  For this reason, in order to simplify the assembly work of the lighting device and improve productivity, a cable connector is arranged on the circuit board of the inverter power supply unit, and each cable is connected via the cable connector without soldering. Are desired to be electrically connected.

  In the case of a configuration in which a cable connector is provided in the inverter power supply unit, an inverter with respect to the length direction of the cold cathode fluorescent tube is considered in consideration of shortening a distance in which each cable is routed and wired (hereinafter referred to as a wiring distance). It is desirable that two cable connectors are provided at both ends of the power supply unit, and each cable is routed from each cable connector. However, a 1-pin cable connector that can handle a relatively high voltage and connects only one cable is not commercially available, and preparing a dedicated 1-pin cable connector that is not a general-purpose component is costly to manufacture. Inconvenience that it is bulky.

  A 2-pin cable connector is also provided at each end of the inverter power supply, and only one terminal of each cable connector is connected to each cable, and the other terminal is not used and left as an empty terminal. It is done. However, in this configuration, there is a possibility that one terminal connecting one end of each cable may be mistaken as the other terminal at the time of assembly, which has various adverse effects.

  Considering the above manufacturing conditions, only one 2-pin cable connector is arranged at one end of the inverter power supply section, and two cables are connected from one end of the inverter power supply section along the longitudinal direction of the lamp cover. It is conceivable that the wiring is routed around.

  However, in this configuration, one cable is routed substantially linearly along the longitudinal direction of the lamp cover, and the other cable is folded back from the cable connector at one end of the inverter power supply to the other end of the inverter power supply. Are routed and wired. The other cable routed from one end of the inverter power supply to the other end is difficult to reduce the curvature turned back from the cable connector, and the wiring distance routed from the cable connector is relatively long. It is necessary to set play for the length in consideration of the ease of routing work and the like. For this reason, in this configuration, the wiring state of the cable changes due to vibration or the like, and in particular, slack is likely to occur in the middle of the other cable routed from the cable connector to the other end of the inverter power supply unit. There is a possibility that the midway part hangs down from the lamp cover. That is, there is a problem in that the illumination light from the cold cathode fluorescent lamp is shaded by the other cable and a good illumination state cannot be obtained.

  Therefore, the present invention provides a second configuration in which the first and second cables are routed from the cable connector disposed at one end of the inverter power supply unit to the other end side of the inverter power supply unit. It is an object of the present invention to provide a cable support structure, a lighting device, and a method for manufacturing the lighting device that can suppress a change in the wiring state of the cable and can maintain a good lighting state by illumination light.

In order to achieve the above-described object, a cable support structure according to the present invention includes a lamp cover member that houses a discharge lamp, a first cable and a second cable for supplying power to the discharge lamp, and a lamp cover.

And a cable support member for removably supporting the portion and restricting the second cable from hanging down from the lamp cover member .

  According to the cable support structure according to the present invention configured as described above, the middle portion of the second cable is supported by the cable support member, so that it is routed from the cable connector to the other end of the inverter power supply unit. The wiring state of the second cable is prevented from changing due to vibration or the like, the middle part of the second cable is prevented from hanging vertically downward from the lamp cover member, and the illumination state by the discharge lamp is maintained well. Is done.

The cable support structure according to the present invention further includes another cable support member for removably supporting the middle portion of the first cable and restricting the first cable from hanging downward from the lamp cover member. Further, it may be provided. As a result, as with the second cable, the wiring state of the first cable is prevented from changing, and the illumination state by the discharge lamp is maintained better.
