Description

[Detailed Description of the Invention] This invention relates to a plate holding device convenient for attaching a control plate to a cabinet of a television receiver or the like.

The control board 11 of the television receiver is conventionally
As shown in the figure, it is attached from the inside of the cabinet body 12.

Piece 13. from the inside of the cabinet body 12. bolt 1
4. It is attached using a nut 15 or the like.

According to this conventional control plate mounting structure, (a) When installing the control plate, a space is required to accommodate the tools, so it is impossible to apply it to a structure where space is limited.

(b) Since the control plate was attached to a separate piece, there were variations in the installation of the separate pieces, which caused the adjustment shafts to be misaligned.

(c) Also, since separate pieces are used, the cost is also high.

(b) Nuts may fall off when installing the control board or during service, resulting in foreign object contamination accidents.
Poor workability and serviceability.

(e) When installing the nut on the top or side plate of the cabinet body, the nut is held in one hand, temporarily tightened, and then the nut is finally fixed, which is a double task, resulting in poor work efficiency and increased man-hours.

(f) If the control board mounting area is hidden behind other parts and cannot be seen from the back of the cabinet, work will be extremely difficult.

(G) Furthermore, when inserting the control into the cabinet, if the control plate is inserted with a large deviation in the axial direction of the alignment axis and aligned with the bolt, the control plate will catch on other parts, so the planar shape of the control plate should be devised. This creates a design inconvenience that must be avoided.

This idea was devised in view of the above-mentioned conventional circumstances.The holder is attached to the control board in advance with one touch, and the head of the holder is projected from the cabinet surface into the cabinet mounting hole and rotated approximately 90 degrees. Accordingly, it is an object of the present invention to provide a plate holding device for attaching and holding a control plate by working from the front side of the cabinet.

An embodiment of this invention will be described below in detail with reference to the drawings.

In FIG. 1, 20 is, for example, a cabinet body of a television receiver, and 21 is a control device mounting portion.

The control device mounting portion 21 is formed such that, for example, a portion of the cabinet body 20 is recessed inward.

A plurality of holes 22, 23, and 24 are formed in the bottom of the control device mounting portion 21 to allow the adjustment shaft to protrude.

Then, through these holes 22, 23.24, adjustment shafts 25, 26
．． A control device board 28 is disposed inside the cabinet body so that the board 27 protrudes.

Furthermore, in the vicinity of the control device mounting portion 21,
Attachment holes 29 and 30 for attaching and fixing the control device board 28 to the cabinet body 20 are formed through the cabinet.

Next, in FIG. 3 illustrating the means for fixing the control device board 28 and the cabinet body 20,
Reference numeral 28 denotes a control device board, and a mounting portion 31 is set on this board.

A holder mounting hole 32 for inserting a holder 37 is formed in this mounting portion 31 .

This holder attachment hole 32 has a substantially circular shape, and a notch 33 is formed in a part of its circumference.

Furthermore, around the holder mounting hole 32, hole-shaped locking portions 34, 35 are formed concentrically with the mounting hole at intervals of 90', for example.
．． 36 are formed.

Next, one end of the holder 37 is inserted into the holder attachment hole 32 with one touch.

This holder 37 includes a board locking part A as a first part,
Interval setting part B and cabinet locking part C as the second part
and are formed in the axial direction.

As shown in FIG. 4, the substrate locking portion A has a slotted portion 38 formed from the tip end in the axial direction, and is tapered.

The substrate locking portion 38 has an annular groove portion 39 formed around its larger diameter side, into which the holder mounting hole 32 is fitted.

Furthermore, an axially protruding portion 40 is integrally formed on a part of the outer periphery of the substrate locking portion A, and corresponds to the notch 33 of the holder attachment hole 32.

When the board locking part A is inserted into the holder mounting hole 32, it is inserted so that the protruding part 40 passes through the notch 33.

Further, the holder 37 is molded from a synthetic resin having elasticity, and can be inserted into the holder mounting hole 32 with the action of the slotted portion 38.

Next, the interval setting portion B of the holder 37 is formed into a brim shape around the holder.

A protrusion 41 is integrally formed on the rotating surface on the side of the board locking portion A.

This protrusion 41 corresponds to the position of the locking parts 34, 35, 36 formed around the holder mounting hole 32, and one of these
can be locked to.

Next, the cabinet locking portion C is connected to the spacing setting portion B.
Together with this, an annular groove portion 42 is formed.

The head is formed into an oval shape, and has, for example, a cross-shaped cut groove 43 formed therein.

Next, the cabinet locking portion C can be passed through the elliptical mounting hole 45 formed in the cabinet by matching its shape.

The mounting hole 45 is formed to penetrate the lower surface of the concave portion of the cabinet body 20.

By inserting the cabinet locking portion C of the holder 37 into the mounting hole 45 and rotating it by 90 degrees, the cabinet locking portion C can be locked to the cabinet.

That is, the relationship between the cabinet locking portion C and the mounting hole 45 is as shown in FIG.

Further, at this time, the protrusion 41 is locked to the locking portion 34 or 36 at the next position rotated by 90 degrees.

Therefore, when the holder 37 is turned, a user can feel that it is in the locked state.

Further, when locked in this manner, the holder 37 does not rotate to an unnecessary position, and the state in which the plate body (cabinet, board) is held is firmly maintained.

This devised device not only fixes the cabinet and the control device board, but also the first. This can be effectively used as a holding device for the second plate.

Further, according to this device, the fixation is performed only by the holder 37, and there is no need to use separate pieces, bolts, nuts, etc. as in the conventional case.

Further, an annular groove portion 39, a protrusion 40° protrusion 41. By using the locking hole 35, it can be temporarily fixed to the board with a single touch.

As a result, the orientation of the holder 37 (longitudinal direction of the ellipse),
The orientation (position) of the control device board 28 and the positional relationship of the mounting holes 45 of the cabinet body 20 are accurately unified for each product.

For this reason, holes 22, 23, 24 in the cabinet body 20
The positions of the adjustment shafts 25, 26, and 27 are also determined accurately.

Furthermore, when attaching the control device board to the cabinet body, it is sufficient to simply insert the cabinet locking portion C of the holder 37 into the mounting hole 45 and rotate the holder 37 by 90 degrees from outside the cabinet.

Therefore, the work can be done from the outside and there is no need to turn bolts inside the cabinet as in the conventional case.

This allows the control device board to be easily installed in a narrow space within the cabinet.

As explained above, according to this invention, one end of the holder is attached to the first plate in advance with one touch, and the other end of the holder is projected from the second plate and rotated. It is possible to provide a plate holding device that is easy to install and has a simple component structure.
