Description

The present invention relates to a synthetic resin chassis of a television receiver, and more particularly, to a synthetic resin chassis employed in a video tape recorder integrated television receiver.

A conventional example will be described with reference to FIGS. FIG. 5 is a plan view of a conventional synthetic resin chassis, FIG. 6 (A) is a side view of a main part of FIG. 5, and FIG. 5 (B) is a longitudinal sectional side view in which the main part of FIG.

The synthetic resin chassis includes a lower element 1 having a longer length in the front-rear direction and an upper element 5 having a shorter length in the front-rear direction. Attachment portions 6 integrally formed on the left and right sides of the upper element 5 are joined to the body 2 in an overlapping manner while being positioned. More specifically, the support 2 is divided into a front post 21 and a rear post 25, and a long strip 62 long in the front and back is formed in a plate-like support 6 having a rib 61 superposed thereon. In addition, one of the two screws 91 and 92 with seats inserted into the long hole 62 is screwed into the front post 21, and the other is screwed into the rear post 25. The rear post 25 shown in FIG. 6B has a boss 27 on the top surface 26 thereof, which is inserted into the long hole 62 of the mounting portion 6. The front post 21 also has a boss (not shown) on its top surface 22 (see FIG. 6B) to be inserted into the long hole 62 of the mounting portion 6.

In a television receiver integrated with a video tape recorder, the lower element 1 of the chassis is called a tray chassis, on which a video deck, a main board, and tuner parts are mounted. The upper element 5 is called an HV chassis, and a power supply board, etc. Is mounted. When the chassis is formed by the lower element 1 and the upper element 5 stacked and joined thereon as described above, the front-to-rear length of the entire chassis is shortened, so that the packaging for transporting the chassis is not necessary. There are advantages of being compact, and of facilitating downsizing by shortening the front and rear length of the accommodation space in the television receiver.

As another conventional example, a tray chassis temporary fixing mechanism has been proposed which is devised so as to easily perform an operation of temporarily fixing a tray chassis on which a heavy object is mounted to a front cabinet (for example, Patent Document 1). reference).

As still another conventional example, in a television receiver, a component fixing device capable of reducing the number of members for fixing components of a display device by adding a component coupling function to a printed board holder and reducing the number of assembling steps is provided. It has been proposed (for example, see Patent Document 2).

However, in the conventional example described with reference to FIGS. 5 and 6, since the operation procedure for connecting the upper element 5 to the lower element 1 includes a troublesome operation of tightening the two screws 91 and 92 with seats, Is not only troublesome, but also because the tightening torque of the seat screws 91 and 92 tends to vary, so that the coupling state of the two elements 1 and 5 tends to vary. There was a problem that the cost increased.

The present invention has been made under the above circumstances, and improves the workability by omitting the fastening work of the seated screw itself and the seated screw from the work procedure when connecting the upper element to the lower element, It is another object of the present invention to provide a synthetic resin chassis of a television receiver in which the number of parts is reduced and the cost of parts is easily reduced, and the coupling state between the lower element and the upper element is less likely to vary.

The synthetic resin chassis of the television receiver according to the present invention includes a lower element and an upper element that are provided over two upper and lower stages, and is integrally molded with the upper element on a support integrally molded with the lower element. The attached parts are connected in an overlapping manner in a state where they are positioned. Then, the overlapping portion of the support and the mounting portion is connected at two front and rear portions, and at the front connection portion, a plate-shaped insertion portion of the mounting portion is abutted against the rising wall of the recessed portion on the support side, And, while the insertion portion is sandwiched between the upper surface and the lower surface of the concave portion, at the rear joint portion, the locking claw is raised on the support body side and can be bent and deformed in the front-rear direction and has a locking claw on the top. A plate-like locking portion on the mounting portion side faces the leg portion, and the locking portion is sandwiched between the locking claw and the support.

With this configuration, the mounting portion of the upper element is connected to the support of the lower element in the vertical position at two points, the front connection point and the rear connection point. It is not necessary to use the seated screw described in 6 and the like, and it is not necessary to use another component instead of the seated screw. Further, since the legs and the recessed portions having the locking claws at the top are integrally formed with the support of the lower element, the mounting state of the mounting portion with respect to the support is stabilized, and the connection state of the lower element and the upper element is stabilized. Is less likely to vary.

In the present invention, a pair of pieces integrally provided on both sides of the insertion portion sandwich the rising wall of the recessed portion in the left-right direction, and the locking portion is opened in the mounting portion to form the locking claw. It is desirable that the leg is formed by the edge of the opening through which the leg is inserted, and that a pair of sides located on both sides of the edge sandwich the leg in the left-right direction. According to this, the mounting portion of the upper element can be attached to the support of the lower element in the vertical direction and the left and right direction at two places, the front connection point and the rear connection point, without using a seated screw or another component replacing the seated screw. It is combined in the positioned state.

In the present invention, the opening is formed by displacing the mounting portion downward with respect to the front joint portion so as to bend the leg portion so that the locking portion can move over the locking claw while bending the leg portion. It is desirable to have an area capable of absorbing the deflection allowance. According to this, after inserting the plate-shaped insertion portion of the mounting portion into the recessed portion of the support, the opening on the mounting portion side is fitted to the locking claw, and the mounting portion is lowered downward around the front joint portion. When the locking portion is displaced by pushing down, the locking portion gets over the locking claw on the top portion while bending the leg portion on the support side, and is clamped by the locking claw and the support. This is easy to do.

合成 The synthetic resin chassis of the television receiver according to the present invention can be configured as follows. That is, a lower element and an upper element are provided over the upper and lower stages, and the mounting part integrally formed on the upper element is joined to the support integrally formed on the lower element in an overlapping manner in a state where the mounting part is positioned. In the synthetic resin chassis of the television receiver, the overlapping portion of the support and the mounting portion is joined at two front and rear portions, and at the front joint portion, at the top of the front post forming the support, A plate-shaped insertion portion on the mounting portion side abuts against a rising wall of the provided recess portion, and the upper and lower surfaces of the recess portion sandwich the insertion portion, and the insertion portion includes While the pair of pieces integrally provided on both sides of the rear side sandwich the rising wall of the recess in the left-right direction, the rear joining portion stands on the top of the rear post forming the support. Raised and deformable in the front and rear direction A plate-like engagement formed by a lip of a leg with a rearwardly projecting locking claw protruding from the crest thereof, which is formed by a lip of an opening formed in the mounting portion and through which the locking claw and the leg are inserted. The locking portion faces each other, and the locking portion is held between the locking claw and the support, and a pair of sides located on both sides of the lip sandwich the leg portion in the left-right direction. The opening is formed by displacing the mounting portion downward around the front connection portion so that the leg portion is bent while the leg portion is bent so that the locking claw can be moved over the locking claw. It is also possible to adopt a configuration that has a size capable of absorbing a bending allowance, the support is provided on both left and right sides of the lower element, and the mounting portions are provided on both left and right sides of the upper element. The operation of the present invention will be described in detail with reference to an embodiment described later.

As described above, according to the present invention, the work procedure for connecting the upper element to the lower element is improved by eliminating the tightening work of the seated screw itself and the seated screw, thereby reducing the number of parts. As a result, the cost of parts can be easily reduced. Moreover, it is possible to provide a synthetic resin chassis of the television receiver in which the coupling state between the lower element and the upper element is less likely to vary.
