Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic device structure such as a cable broadcasting terminal device, and more particularly, to a structure of an electronic device in which a fluorescent display tube and a function display LED element are provided on a built-in printed circuit board.

[0002]

[Prior art]

 As is well known, in an electronic device such as a cable broadcasting terminal device, a fluorescent display tube for displaying various operating states and a plurality of LED elements for displaying a functional state are incorporated in the housing of the electronic device. There is. That is, FIG. 3 is a cross section of a conventional cable broadcasting terminal device, and a fluorescent display tube 3 for displaying various operating states and the like is incorporated inside the front panel 2 of the terminal device housing 1.

The fluorescent display tube 3 is indirectly held by a printed circuit board 4 fixed to the front panel 2 by using a spacer (not shown). That is, parts such as the changeover switch 6 and the functional element 7 are arranged on the surface of the printed circuit board 4, and the display tube holder 8 is kept on the surface of the printed circuit board 4 by a plurality of elastic claws 8a. The fluorescent display tube 3 is fixed in this state, and the fluorescent display tube 3 is held on the front side of the display tube holder 8.

The bases of the leads 9 a of the plurality of LED elements 9 are fixed to one side of the printed circuit board 4, and the light emitting heads 9 b of these LED elements 9 correspond to the functions of the front panel 2. The functional state of the cable broadcasting terminal equipment is displayed by being inserted into the display hole 10 and emitting light from these light emitting heads 9b.

[0005]

[Problems to be solved by the device]

 By the way, the above-mentioned fluorescent display tube 3 has a considerable thickness L1, and the main body of the display tube holder 8 is separated from the surface of the printed board 4 by a distance L2 in order to secure a mounting space for the changeover switch 6 and the functional element 7. Since the leads 9a of the LED element 9 have a considerable length L 3 in the electronic device structure having such a structure, the leads 9a themselves have a structure that is very easily deformed. is there. For this reason, the position of the light emitting head 9b of the LED element 9 mounted on the printed circuit board 4 is extremely unstable. Therefore, when the printed circuit board 4 mounted with the LED element 9 is mounted on the front panel 2, deformation occurs Due to the influence of the leads 9a, it is often the case that the light emitting head 9b of each LED element 9 cannot be inserted into the corresponding function display hole 10. In the actual assembling process, the print substrate 4 is put on the front panel 2 to display the function display. After confirming the positional deviation of the light emitting head 9b of the LED element 9 with respect to the hole 10 and correcting the position of the light emitting head 9b, it was necessary to fix the print substrate 4 to the front panel 2. Needless to say, the necessity of adjusting the position of the light emitting head 9b is an obstacle to the efficiency of the assembly process of the electronic device, and when there are a plurality of LED elements 9, it is a very difficult work. However, the assembly process required skill and automatic assembly was completely impossible.

In view of the problems of the conventional electronic device structure as described above, the object of the present invention is that the position of the light emitting head of the LED element mounted on the printed circuit board is very stable and adjustment is necessary. Instead, there is a need to obtain a structure in which the same light-emitting head can be reliably associated with the function display hole on the front panel.

[0007]

[Means for Solving the Problems]

 To achieve this object, the present invention arranges a display tube holder for fixing to a printed circuit board inside a front panel of an electronic device housing, holds the fluorescent display tube in the display tube holder, and In an electronic device structure in which a light emitting head of an LED element supporting a lead is exposed to a function display hole formed in the front panel to perform a function display, a display tube holder corresponding to the LED element is provided. The present invention proposes an electronic device structure in which an extension wall is provided with a holding part having a holding groove formed on the end face, and the holding groove holds a part near the head of the LED element.

[0008]

[Embodiment] The embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2 showing the cable broadcasting terminal equipment, the same structural parts as those in FIG. 3 described above are denoted by the same reference numerals.

That is, as shown in FIG. 2, a printed circuit board 4 fixed to the front panel 2 using a spacer (not shown) is arranged inside the front panel 2 of the terminal device housing 1. Parts such as a changeover switch 6 and a functional element 7 are arranged on the surface of the printed circuit board 4 and the display tube holder 8 is fixed by a plurality of elastic claws 8a in a spaced state. The fluorescent display tube 3 is held on the front side of 8.

Further, on one side of the printed circuit board 4, leads 9a of a plurality of LED elements 9 into which the light emitting head 9b is inserted into the corresponding function display holes 10 of the front panel 2 are fixed. The functional state of the cable broadcasting terminal device is displayed by the light emission of the light emitting head 9b. Reference numeral "11" in FIG. 2 is a power button for operating the changeover switch 6.

As shown in FIG. 1, an elongated wall 8b is integrally formed on a side portion of the display tube holder 8 corresponding to the LED element 9, and a neck portion of a lead 9a of the LED element 9 is formed on the extended wall 8b. A pair of holding portions 12 capable of holding the are molded. That is, these holding portions 12 each have a holding groove 13 extending in the alignment direction of the leads 9a of each LED element 9 and having a groove width substantially equal to the outer diameter of the lead 9a, and these holding grooves 13 extend. It is open to the end face of the wall 8b.

Since the electronic device structure according to the illustrated embodiment has the above-mentioned structure, when the display tube holder 8 is fixed to the printed board 4, the neck portion of the lead 9a of the LED element 9 fixed to the printed board 4 is fixed. May be held in the correspondence holding unit 12. That is, since the holding groove 13 of each holding portion 12 is released to the end surface of the extension wall 8b, the leads 9a of the LED element 9 are passed through the holding groove 13 from these releasing portions, and the elastic claw 8a is used to display the display tube. When the holder 8 is fixed to the printed circuit board 4, each holding portion 12 abuts the bottom surface of the light emitting head 9b of the LED element 9 and the position and direction of each light emitting head 9b are specified, as shown in FIG. It Therefore, the position and the direction of the light emitting head 9b of each LED element 9 mounted on the printed circuit board 4 are very accurate, so that the printed circuit board 4 can be fixed to the front panel 2 only. Since the light emitting head portion 9b of each LED element 9 is inserted into the function display hole 10 of FIG. 1, the assembling process can be simplified.

Although the present invention is applied to the cable broadcasting terminal device in the above-mentioned embodiment, it is needless to point out that the present invention can be applied to other electronic devices.

[0014]

[Effect of device]

 As is apparent from the above description, according to the present invention, since the holding portion is provided on the extension wall of the display tube holder to hold the portion of the LED element near the head, the function display hole of the front panel is held. The light emitting head of the LED element can be accurately faced to the LED, and a structure that does not require the position adjustment of the light emitting head when assembling the front panel and the printed circuit board can be obtained. And there is an effect that can achieve automation.
