Description

Digitron holder assembly

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digitron holder assembly, and more particularly to a digitron holder assembly in which the visible angle of the digitron is enlarged.

Digitron accelerates to a direct or positive voltage the hot electrons emitted from a series cathode called a filament in a transparent vacuum container on one side. An electron tube which emits light on a phosphor coated on an anode side and displays a pattern. A fluorescent display device mainly displays numeric functions such as counters and measuring devices and functions of electronic products. It is one of the fluorescent fluorescent displays used to display.

As an example of an electronic product, in the case of a video cassette recorder (VCR), each mode is set by a function selection button installed on the front panel or a remote controller. The digital display improves the user's ease of use by notifying the user of which mode is being executed.

In the video cassette recorder, as shown in FIG. 1, the front panel Fp is mounted on the front surface of the main chassis Mc, and the main circuit board Cm is horizontally installed on the bottom of the main chassis Mc. In general, the front circuit board Cf is vertically installed on the rear surface of the front panel Fp.

However, when the main and front circuit boards (Cm) (Cf) are separated into two, the so-called one type of electronic circuits using only the main circuit board (Cm) due to the increased assembly process and production cost of the product. Video cassette recorders of one type circuit boards have been developed. In the video cassette recorder of the one-type circuit board, a digitron is provided by a holder in front of the upper surface of the main circuit board.

As shown in FIGS. 2A and 2B, the conventional digitron holder has a window Wd formed on the front surface of the front panel Fp, and the window Wd of the front panel Fp is light-transmitting ( A window panel Wp having a high optical property is mounted.

In addition, the main circuit board (Cm) is installed horizontally on the bottom of the main chassis (Mc), the holder 10 of the synthetic resin molded body is mounted in front of the upper surface of the main circuit board (Cm) to be located behind the window (Wd) do.

The holder 10 is formed to have a front opening space 12 so that the digitron D is received by the edge 11, and the storage space 12 is stored in the edge 11 of the holder 10. The support piece 13 for preventing the detachment of the digitron D is formed. At this time, the support piece 13 supports the entire surface of the digitron (D) to prevent the departure from the storage space (12).

On the other hand, the holder 10 has a snap hook (14) is formed on each of the lower sides of the rim 11, the snap hook 14 is to correspond to each other in the coupling hole (Ho) of the main circuit board (Cm) The digitron D is inserted into and coupled to the upper surface of the main circuit board Cm by being accommodated in the receiving space 12 of the holder 10.

However, in the conventional digitron holder as described above, since the digitron D is mounted relatively far from the window Wd of the front panel Fp by the holder 10, the viewing angle of the digitron D is There was a problem that the relative reduction in the use of the product has been a problem.

For example, since both sides of the main circuit board Cm must be spaced about 6 mm apart in order to perform the soldering process automatically by a soldering machine from the edge inward, the front side of the main circuit board Cm. The position of the holder 10 mounted on the upper surface is limited.

In addition, the main circuit board Cm is mounted to protrude a predetermined distance toward the front of the main chassis Mc, but the protruding distance of the main circuit board Cm is a material that is vulnerable to interference and impact of the front panel Fp. Are limited.

Since the digitron D is mounted at a relatively long distance from the window Wd of the front panel Fp as described above, the light of the digitron D is projected to the window W by a relatively long distance and is viewed in a limited range. Will be greatly reduced.

On the other hand, since the holder 10 is manufactured only in a structure for mounting the digitron (D) to the main circuit board (Cm), in order to mount the digitron (D) to the front circuit board (Cf), a separate holder must be manufactured. There was a problem.

This raises production costs, such as the need for new molds for the manufacture of the holder, as well as delays the development and production period of electronic products. In particular, such a problem is raised as a larger problem when a variety of models of electronic products are produced.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to increase the viewing angle of the digitron by a simple configuration and structure to facilitate the use of the product, the type of electronic products Accordingly, the holder can be easily compatible, thereby reducing the production cost of the product, as well as providing a digitron holder assembly which greatly shortens the development and production period of the electronic product.
