Description

[Detailed description of the invention] The present invention relates to a display device for displaying 0 in various ways, such as time display in a clock device, tape running amount display in a tape recorder, and operation status display. It is an object of the present invention to enable display electronic components such as light emitting diodes, optical display tubes, and liquid crystal panels to be easily attached, and to be able to hold them stably so that they are hardly affected by external shocks.

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

First, FIGS. 1 and 2 show equipment to which the display device of this embodiment is applied, with FIG. 1 showing a clock device and FIG. 2 showing a cassette tape recorder with a radio receiver, respectively.

The clock device shown in FIG. 1 uses four day-shaped 7-element R-type light emitting diodes as electronic components for displaying time, and has a time display section 1a. The cassette tape recorder with a receiver has a tape counter section 1b which uses three 7-element type light emitting diodes in the same day shape as display electronic components to display the amount of tape travel.

The structure of the counter part 1b will be explained with reference to FIGS. 3 and 4. A guide body 3 is integrally formed with an elastic material such as rubber in guide body positioning holes 2a, 2a provided in the printed circuit board 2. Positioning boss 3 protruding from the bottom of
Insert a, 3a.

At this time, the positions of the recess 3b of the guide body 3, the elongated hole 3C, and the terminal insertion hole 2b of the printed circuit board 2 are made so that they match so that the display electronic component 4 made of a light emitting diode can be inserted smoothly. It is set to tighten.

That is, when the guide body 3 is positioned on the printed circuit board 2, the flange 4a of the display electronic component 4 is inserted into the recess 3b of the guide body 3.
When inserted and fitted, the positional relationship is such that the lead terminals 4b of the display electronic component 4 are automatically inserted into the terminal insertion holes 2b of the printed circuit board 2 through the elongated holes 3C of the guide body 3.

In this way, when the terminals 4b of the plurality of display electronic components 4 are inserted into the terminal insertion JL2b of the printed circuit board 2 through the guide body 3 and soldered to the conductive foil of the printed circuit board 2, the terminals 4b of the plurality of display electronic components 4 are The through hole 5C of the mounting frame 5 integrally molded from synthetic resin or the like is fitted into the convex portion 4C which is the display portion of the display electronic component 4.

At this time, the printed circuit board 2 and the mounting frame 5 are positioned by the positioning bosses 5a, 5a and the positioning holes 2C, 2C, and the mounting frame 5 is printed with the screws 8 while holding down the flange 4a of the display electronic component 4. It is fixed to the substrate 2.

This mounting frame 5 is integrally provided with elastic locking pieces 5b, 5b and an engagement hole 5d so as to face each other with the plurality of through holes 5C in between. Fit the protrusion 6a provided at one end and connect the other end 6b to the locking piece 5.
b and 5b, and further inserting the front protrusion of the transparent panel 6 into the opening lower a of the front plate 7 to complete the display block.

Note that the printed circuit board 2 is fixedly attached to, for example, a front plate 7.

In such a display block, when inserting the display electronic component 4, the elongated hole 3C and the recess 3b of the guide body 3, which is positioned and fixed on the printed circuit board 2, match the terminal insertion hole 2b. Connect the terminal 4b of the electronic component 4 to the long hole 3C.
After inserting the terminal 4b into the terminal insertion hole 2b, the terminal 4b is automatically inserted into the terminal insertion hole 2b by simply fitting the collar 4a into the recess 3b, making the operation very simple.

Furthermore, the display electronic component 4 is constructed by fitting the concave portion 3b of the guide body 3 and the flange portion 4a of the display electronic component 4, and
Positioning in the front, back, left, and right directions is achieved accurately by fitting the convex portion 4C, which is the display part, with the rectangular hole 5C of the mounting frame 5, and further positioning in the vertical direction is performed by fitting the display electronic component 4 into the rectangular hole 5C.
Since this is done by holding the flange 4a between the four parts 3b of the guide body 3 and the mounting frame 5, the position of the display electronic component can be accurately determined.

The guide body 3 that receives the flange 4a of the display electronic component 4 is made of an elastic material such as rubber, so even if the device is subjected to an external impact force such as when it is dropped, it will not be damaged. It absorbs and protects the display electronic component 4.

Furthermore, since the guide body 3 is made of an elastic material such as rubber, even if there is some error in the finished dimensions of the display electronic component 4, simple work and accurate positioning can be performed without any problem. be.

As described above, the present invention has a structure in which a display electronic component is sandwiched between a mounting member and a holding member made of an elastic material, and is integrally fixed to a printed circuit board, and a translucent panel is detachably attached to the mounting member. Since the display electronic components can be easily positioned, the holding member is made of an elastic material, which allows accurate positioning by absorbing dimensional errors in the display electronic components. Display electronic components can also be protected from force.

Furthermore, by making the translucent panel removable from the mounting member, it has the excellent effect of improving workability during assembly and service.
