[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for electronic display components which can easily and stably fix electronic display components on a printed wiring board of various electronic devices.

[0002]

2. Description of the Related Art Electronic appliances such as light emitting diodes, liquid crystals or fluorescent display tubes are mounted on household electric appliances or measuring instruments such as televisions, radios, video tape recorders and stereos. Have been. These display the sound volume, frequency, rotation speed, time, measurement result, and the like in the form of numbers or figures.

For example, when considering a video tape recorder, a display unit is generally arranged on a side surface (specifically, a front surface) of a main body for its use in many cases.
Therefore, usually, a display component substrate is erected on a substrate (motherboard) disposed near the bottom of the main body, and electronic display components are mounted on the substrate in parallel, whereby the display portion is disposed on the side surface of the main body. Was like that.

Accordingly, a plurality of substrates are required, and
Various inconveniences have occurred in the manufacturing process. For example, in the process of erecting a board for electronic display components on a motherboard, installation work is troublesome after other components are mounted, so if you do it at the initial stage, it can be a hindrance to other work There is. That is, as described above, since the display unit is arranged on the side surface of the main body, the board for electronic display components is often located outside the end of the motherboard. Then, it becomes a hindrance in, for example, a flow operation in a manufacturing process.

Accordingly, the present invention solves the above-mentioned problems, and can share a motherboard without requiring a unique substrate for electronic display components separate from the motherboard, thereby improving the efficiency of operations at the time of manufacturing electronic devices and the like. An object of the present invention is to provide an electronic display component fixture that can be realized.

[0006]

According to the first aspect of the present invention, there is provided a flat plate for mounting a plate-shaped electronic display component on an upper surface. A plate-like mounting body, a spring member formed on a part of the plate-like mounting body, for urging the electronic display component placed above from its lower surface upward, and a swing shaft for the plate-like mounting body. Provided through
The electronic display component has at least a positioning member with which the upper surface of each of the two corners is in contact with the electronic display component, and after the electronic display component is mounted on the plate-like mounting body, the plate is set via the swing shaft. By swinging in parallel to the upper surface of the mounting body,
A holding member that abuts the positioning member on the upper surface of the electronic display component and holds the electronic display component in cooperation with the spring member, and the holding member is provided on the holding member, and the holding member is swung. And a locking member that engages with a locking piece provided on the plate-shaped mounting body and locks the rocking holding member. The plate-shaped mounting body is printed by a support member. A fixture for electronic display components supported on a wiring board or the like,
The plate-like mounting body is arranged on the support member from a predetermined pre-assembly position where the plate-like mounting body is substantially horizontal with respect to the printed wiring board, from a state perpendicular to the printed wiring board. A fixing tool for an electronic display component, comprising: a positioning mechanism that is rotatably mounted to an assembly completion position shifted by a predetermined angle and that can position the plate-shaped mounting body at the assembly completion position.

When the electronic display component is fixed using the electronic display component fixing device, the electronic display component is first placed on the upper surface of the plate-like mounting member. At this time, the electronic display component is pressed by, for example, a hand, and the spring member is moving downward. Next, the holding member is swung in the direction of the electronic display component via the swing shaft, and the positioning member provided on each holding member is moved to the upper surface of each of the two corners of the electronic display component. Then, the locking member engages with the locking piece of the plate-shaped mounting body, and the position of the holding member is fixed.

In this state, when the pressing force applied to the electronic display component is released, the spring member urges the electronic display component upward to contact the positioning member. As described above, the spring member and the holding member cooperate to hold the electronic display component, and the electronic display component is fixed on the plate-like mounting body.

The plate-like mounting body is supported on a printed wiring board or the like by a support member, and the plate-like mounting body is mounted on the support member and the plate-like mounting body is mounted on the printed wiring board. From a predetermined pre-assembly position, which is substantially horizontal, to an assembly completion position, which is displaced by a predetermined angle from a state perpendicular to the printed wiring board. As in the video tape recorder described above, in the case of an electronic device in which the display unit is disposed on the side surface of the main body, if the printed wiring board in the present invention is the motherboard, the assembly completion position referred to here is This indicates a completed state in which electronic display components are finally arranged. Therefore, according to the present invention, the motherboard (printed wiring board in the present invention) can be shared without requiring a unique substrate for electronic display components different from the motherboard.

Further, in the above-mentioned conventional example, since the display portion is disposed on the side surface of the main body, the substrate for the electronic display component is positioned outside the end of the motherboard, so that, for example, the assembly process in the manufacturing process is performed. It was in the way of time. In the present invention as well, the plate-shaped mounting body at the assembly completed position is similarly located outside the end of the motherboard and is positioned, but even in such a case, according to the present invention,
The plate-like mounting body can also be moved to a pre-assembly position substantially parallel to the printed wiring board. In this pre-assembly position, the plate-shaped mounting body can be arranged inside the end of the motherboard, so that it does not become an obstacle during the production process, for example, during the flow work, and as a result, the work efficiency is improved I do.

[0011] Then, the positioning mechanism can be positioned at the assembly completion position. This assembly completion position is a position shifted by a predetermined angle from a state perpendicular to the printed wiring board, but since there is a positioning mechanism, the plate-like mounting body is moved to the “assembly completion position” and held. Can be realized very easily.

The assembling completion position is set at a position shifted by a predetermined angle toward the pre-assembly position from a state perpendicular to the printed wiring board, and is mounted on the plate-like mounting body. The display surface of the electronic display component may be configured so as to face upward at a predetermined angle from the horizontal direction at the assembly completed position. As the assembly completion position shifted by a predetermined angle from the state perpendicular to the printed wiring board, there may be a case where the display surface of the electronic display component faces upward by a predetermined angle and a case where it faces downward. In a video tape recorder or the like to which the present invention is applied, for example, the user often looks at the display surface from a little above, considering the arrangement place in the case of use. Therefore, it is preferable that the display surface is slightly upward in this manner, since the display contents are easy to see. On the other hand, in the case of adopting an apparatus in which it is more preferable that the display surface is oriented slightly downward, the assembly completion position may be set so that the display surface faces slightly downward.

In the above-mentioned positioning mechanism, for example, as set forth in claim 3, the plate-like mounting body moved to the assembly completion position is locked to the support member to perform positioning at the assembly completion position. The plate mounting body moved to the assembly completion position is locked to the printed wiring board to perform positioning at the assembly completion position. You may comprise so that it may be. When the plate-like mounting body is moved to the assembly completion position and positioned, it is often mounted on a printed wiring board or the like. There is no problem at all.

The electronic display component fixing device according to a fifth aspect of the present invention is further configured such that the electronic display component fixing device can be positioned at the pre-assembly position or at an assembly halfway position shifted from the pre-assembly position by a predetermined angle toward the assembly completion position. Is provided. In this case, the positioning at the pre-assembly position or the mid-assembly position is achieved by locking the plate-like mounting body to the support member at the pre-assembly position or the mid-assembly position. It is conceivable to configure the second positioning mechanism so as to perform this.

[0015] As described above, the plate-like mounting body is positioned with respect to the printed wiring board so that the plate-like mounting body does not protrude beyond the end of the motherboard during a flow operation in a manufacturing process or the like. It has been mentioned that it can also be moved to a substantially parallel pre-assembly position. However, if you can only move,
For example, there is a possibility that what has been moved to the pre-assembly position may move to or near the assembling completed position due to work during the assembly work. Therefore, if the positioning is performed at the pre-assembly position, there is no need to worry.

Note that this is not necessarily limited to the pre-assembly position, and in consideration of the problem during the assembly work, the plate-shaped mounting body does not protrude beyond the end of the motherboard. Therefore, the positioning may be performed at an assembling position that satisfies such a condition. Further, positioning may be performed at both the pre-assembly position and the assembling position. In this case,
For example, in an initial step of the assembly work, a pre-assembly position where the plate-like mounting body is substantially horizontal is appropriate, and in an intermediate step, another component is disposed below the plate-like mounting body. Since it is conceivable that the position during assembly may be appropriate, it is possible to perform positioning at a plurality of positions in this way. Of course, depending on the work content, it may be preferable to freely move the plate-like mounting body between the three positions of the pre-assembly position, the mid-assembly position, and the assembly completion position. It is not necessarily possible to move only in the order of the assembly completion position.

According to a seventh aspect of the present invention, in the above-described electronic display component fixing device, the plate-like mounting member and the support member have insertion holes into which the lead wires of the electronic display component can be individually inserted. It is characterized by the following. By inserting the lead wires into the insertion holes provided in the plate-shaped mounting body and the support member, the lead wires can be individually held. As the insertion hole, a configuration in which the entrance is wide and the exit is narrow is preferable. For example, a truncated cone-shaped or truncated square pyramid-shaped insertion hole may be employed. With the insertion hole having such a configuration, the lead wire is guided to the tapered inner surface when the lead wire is inserted, so that the insertion operation can be easily performed.

It is preferable that the insertion holes of the plate-like mounting member and the support member be positioned on the same straight line at the above-mentioned pre-assembly position, and that the lead wire be inserted at the pre-assembly position. Then, when the plate-like mounting body is moved to the assembly completion position, the lead wire is also bent together.

In the case where the present invention is applied to the electronic display component fixing device according to the second aspect, the lead wire can be moved more perpendicularly to the printed wiring board than the plate-like mounting member. The angle at which the lead wire is bent is reduced, and the possibility that the inconvenience that the lead wire is broken occurs is reduced.

5b.

More specifically, the support member 5 is supported by the support legs 8.
7a and 87b, the first locking projections 83a and 83b and the second locking projections 85a and 85b are horizontally and vertically with respect to the printed wiring board 100, respectively. It is not to be. That is, as shown in FIGS. 8 and 9, the first locking projections 83a and 83b are arranged to be shifted upward by a predetermined angle α from a position that is horizontal with respect to the printed wiring board 100. On the other hand, the second locking projections 85a and 85b are arranged so as to be shifted from the position perpendicular to the printed wiring board 100 toward the first locking projections 83a and 83b by a predetermined angle α. Become.

The distance between the stoppers 55a, 55b of the connecting legs 50a, 50b and the stopper projections 56a, 56b is determined by the first locking projections 83a, 83b and the second locking projections 85a, 85a. The width is approximately equal to 85b.

0 (a) and (b) are one support plate 81a,
a, a first locking projection 83a, a second locking projection 85a,
One connecting leg 50a, mounting portion 51a, stopper 55
a, only the protrusion 56a for the stopper is shown. It goes without saying that the locking state on the opposite side is the same,
In the case where the description is made with reference to 0, only the sign on one side is represented.

As shown in FIG. 10A, at the pre-assembly position, the first locking projection 83a is held between the stopper 55a and the stopper projection 56a. The other end of the stopper 55a is locked to the second locking projection 85a. This restricts the swing of the connecting leg 50a in the direction of the arrow (a) and the direction of the arrow (b) in the figure. Further, the stopper projection 56a abuts on the first locking projection 83a, thereby restricting movement in the direction of arrow (c), and plays a role of so-called "prevention of detachment".

On the other hand, as shown in FIG. 10B, the stopper 55a and the stopper
The second locking projection 85a is sandwiched between the second projection 85a and the second locking projection 85a. In addition, the side surface of the connecting leg 50a contacts the connecting portion 82a.
This restricts swinging in the directions indicated by arrows (d) and (e). In this way, it is once positioned at the assembly completion position. The movement from the pre-assembly position to the assembly completion position, or vice versa, can be performed by applying a slightly stronger force to get over the regulating protrusions or the like.

As described above, at the pre-assembly position, the first protrusion is located between the stopper 55a and the stopper projection 56a.
The second locking projection 85a is sandwiched between the stopper 55a and the stopper projection 56a at the assembly completed position. As described above, the first locking projection 85a is held between the stopper 55a and the stopper projection 56a. The locking projection 83a is arranged to be shifted upward by a predetermined angle α from a position that is horizontal with respect to the printed wiring board 100, and the second locking projection 85a is
Are shifted toward the first locking projection 83a by a predetermined angle α from a position perpendicular to the first locking projection 83a.

Therefore, as can be seen from FIGS. 8 and 9, when the mounting surface 3a is positioned at the pre-assembly position, the mounting surface 3a of the plate-like mounting body 3 is positioned at a predetermined angle α And when it is positioned at the assembly completed position, the mounting surface 3a of the plate-like mounting body 3
Is directed in a direction inclined upward by a predetermined angle α from the side. Therefore, the display surface of the electronic display component 7 mounted on the mounting surface 3a is not directly beside, but slightly upward (a predetermined angle α).
Will be positioned in the state facing.

The members described above can be integrally formed of various plastics, for example, various materials such as a polyamide condensate and a polyester polymer. Next, a procedure for fixing the electronic display component 7 in the electronic display component fixture 1 of the present embodiment having the above-described configuration will be described, and the operation and effect will be appropriately referred to.

First, the electronic display component 7 is mounted on the mounting surface 3a of the plate-shaped mounting body 3, and at this time, the electronic display component 7 is pressed by, for example, a hand. Then, the spring members 25a, 25b

0b is swung in the direction of the electronic display component 7, and the vertical positioning members 35a, 35b provided on the respective holding members 30a, 30b are moved to the upper surfaces of the two corners of the electronic display component 7. Then, the locking members 33a, 33b
Are engaged with the locking pieces 37a, 37b to hold the holding members 30a, 3
The position of 0b is fixed.

In this state, when the pressing force applied to the electronic display component 7 is released, the spring members 25a and 25b urge the electronic display component 7 upward to cause the vertical positioning member 35 to move.
a, 35b. Thus, the spring member 25
a, 25b and the holding members 30a, 30b cooperate to hold the electronic display component 7, and the electronic display component 7 is fixed to the mounting surface 3a.

On the other hand, the support member 5 is provided with support legs 87a, 87
b is a mounting hole 101a provided in the printed wiring board 100,
101b, the check pieces 89a, 89
With the function of b, it can be fixed to the printed wiring board 100 reliably. When the support member 5 is fixed to the printed wiring board 100, the printed wiring board 100 is provided with a lead wire insertion hole (not shown) at a position corresponding to the insertion hole 61 provided in the support member 5.

The mounting portions 51a on the plate-like mounting body 3 side
When the 51b is fitted on the rotating shafts 70a and 70b of the support member 5, the two are connected, and the plate-like mounting body 3 is supported on the printed wiring board 100 by the support member 5. On this occasion,
As described above, the plate-like mounting body 3 is rotatably attached to the support member 5, and the plate-like mounting body 3 is moved from the pre-assembly position (see FIG. 8) to the assembly completion position (see FIG. 9). It is configured to be reversibly rotatable up to.

As described above, the following effects can be obtained by being movable between the pre-assembly position and the assembly completion position. For example, in the case of an electronic device such as a video tape recorder in which a display portion is disposed on a side portion of a main body, if the printed wiring board 100 in this embodiment is a motherboard, the assembly completion position (see FIG. 9) indicates a completed state in which the electronic display component 7 is finally arranged.
Therefore, according to the present embodiment, the motherboard (the printed wiring board 10 according to the present embodiment) does not require a unique substrate for electronic display components different from the conventional motherboard.
0) can be shared.

When the display portion is arranged on the side surface portion of the main body, the substrate for the electronic display component protrudes outside the end of the motherboard and is located in the manufacturing process, for example, at the time of a flow operation. I was Also in this embodiment, the printed wiring board 1 is similarly placed at the assembly completion position shown in FIG.
A state in which it is located outside the end of 00 is considered. However, according to this embodiment, the plate-like mounting body 3 can be moved to a pre-assembly position substantially parallel to the printed wiring board as shown in FIG. The mounting body 3 can be arranged inside the end of the printed wiring board 100. Therefore, there is no hindrance in, for example, a flow operation in a manufacturing process, and as a result, efficiency of the operation is realized.

Further, as shown in FIG. 8, when other parts are to be mounted below the plate-like mounting body 3 at the pre-assembly position, the work is set to the assembly completion position in FIG. If it is performed, the work is easy, and if necessary, it may be returned to the pre-assembly position shown in FIG. Particularly, in the case of a video tape recorder, a tape drive-related component is often located at that position, which contributes to an improvement in work efficiency.

As described above, the effects achieved by being movable between the pre-assembly position and the assembly completion position have been described. Next, effects brought about by other configurations will be described below. According to the fixture 1 for an electronic display component of the present embodiment, the plate-shaped mounting body 3 can be once positioned at the above-described pre-assembly position and the assembly completion position. This assembly completion position is a position shifted by a predetermined angle from a state perpendicular to the printed wiring board, but since there is a positioning mechanism, the plate-like mounting body is moved to the “assembly completion position” and held. Can be realized very easily.

According to the configuration of the present embodiment, when moving from the pre-assembly position to the assembling completion position or vice versa, a slightly stronger force is applied to the protrusions and the like that regulate the movement. I tried to get over it. Therefore, in the state between the pre-assembly position and the assembly completion position, the side surfaces of the stoppers 55a and 55b
5a and 85b are in contact with the side surfaces. Therefore, it is not a reliable positioning, but it is possible to perform a positioning that does not move even when a weak force is applied from the outside due to a frictional force between the two. Therefore, the following effects are obtained.

For example, in the initial step of the assembly work,
As shown in FIG. 8A, the position before the assembly where the plate-like mounting body 3 is substantially horizontal is appropriate, and another part is arranged below the plate-like mounting body 3 in an intermediate step. In some cases, it may be appropriate to move the assembly to the assembly completion position a little more. Therefore, it is convenient to be able to temporarily determine the position even during such an assembly process. Also, assuming that this assembling position is necessary only in the intermediate step of the assembly work, it is not necessary to perform a reliable positioning such as an assembling completed position, that is, a positioning that does not move even if a certain amount of force acts. As described above, positioning by frictional force may be used. Of course, depending on the contents of the work, there may be a case where reliable positioning is required in the middle of the assembly. In such a case, for example, in the above-described embodiment, the first locking projection 83 is used.
The third locking projection may be provided at a predetermined position between the second locking projection 85a and the second locking projection 85b.

In the present embodiment, both the plate-like mounting body 3 and the support member 5 are provided with lead wire insertion members 40 and 60. Therefore, by inserting the lead wire 9 of the electronic display component 7 into each of the insertion holes 41 and 61, the lead wire can be individually held. And this insertion hole 41,
61 is a truncated quadrangular pyramid having a wide entrance and a narrow exit, so that each insertion hole 4
The insertion work can be easily performed by being guided to the tapered inner surfaces of the first and the 61st. The configuration of the insertion holes 41 and 61 is not limited to a truncated quadrangular pyramid, but can be variously adopted, such as a truncated cone.

In connection with the above, in the above embodiment, the assembling completion position is set at a position shifted by a predetermined angle from the state perpendicular to the printed wiring board 100 toward the pre-assembly position, and The display surface of the electronic display component 7 placed on the body 3 is configured to face upward at a predetermined angle from the horizontal direction at the assembly completed position. For example, when the present invention is applied to a video tape recorder or the like, the user often looks at the display surface from slightly above in consideration of an arrangement place or the like in a normal use. Therefore, it is preferable that the display surface is slightly upward in this manner, since the display contents are easy to see. Furthermore, the angle at which the lead wire is bent is smaller than that in which the plate-like mounting body 3 is moved to a state perpendicular to the printed wiring board 100, and the possibility that the lead wire is broken is less likely to occur. Become.

As described above, the present invention is not limited to such embodiments at all, and can be implemented in various modes without departing from the gist of the present invention. For example, in the above embodiment, as shown in FIG.
Although 3a and the second locking projection 83b are themselves shifted by a predetermined angle from the horizontal and vertical directions, they may be configured as shown in FIG. In this case, the first locking projection 83a and the second locking projection 85a are respectively moved to the horizontal direction by a predetermined angle α from the position shown in FIG. The projecting piece 83a is in the horizontal direction,
Is shifted by 2α from the vertical direction.
In this case, the position of the stopper 55a and the stopper projection 56a is shifted from the position in FIG. 10 so that the connecting leg 50a is positioned at the same position as in FIG.

Further, in the above embodiment, the display surface of the electronic display component 7 placed on the plate-like placing body 3 is configured to face upward at a predetermined angle from the horizontal direction at the assembly completion position. On the other hand, in a case where it is preferable to use the electronic display component 7 in such a manner that it is preferable that the electronic display component 7 is oriented slightly downward,
The assembly completion position may be set so that the display surface is slightly downward. For example, in the case shown in FIG. 12, the first locking projection 83a is provided in the horizontal direction, and the second locking projection 8a is provided.
5a is provided in the vertical direction. And FIG.
As shown in FIG.
a first locking projection 83 between the first projection 83a and the stopper projection 56a.
a is sandwiched in this case, FIG.
The connecting leg 50a comes at the same position as in FIG. However, 1
As shown in FIG. 2 (b), at the assembly completion position, when the second locking projection 85a is sandwiched between the stopper 55a and the stopper projection 56a, in this case, the connecting leg 50a
Is tilted downward by a predetermined angle α from the horizontal direction, and as a result, the display surface of the electronic display component 7 mounted on the plate-like mounting body 3 slightly turns downward from the horizontal direction.

In the positioning mechanism of the above embodiment, the first and second locking projections 85a and 86a are sandwiched between the stopper 55a and the stopper projection 56a.
This is realized by the side surface of Oa being in contact with the connecting portion 82a. For example, assembling is performed by locking a part of the plate-like mounting body 3 moved to the assembly completion position to the printed wiring board 100. You may comprise so that positioning in a completion position may be performed. When the plate-shaped mounting body 3 is moved to the assembly completion position and positioned, it is often mounted on the printed wiring board 100. There is no problem.

Another embodiment in which positioning at the assembly completion position is performed by locking a part of the plate-like mounting body 3 moved to the assembly completion position to the printed wiring board 100 is described below.
