Abstract

PURPOSE:To make it possible to mount a transformer with low cost and high workability and reliability by providing the transformer cabinet with rib, boss, resilient projection, etc. as one body with the cabinet. CONSTITUTION:A transformer 9 is inserted into a rib that is provided as one body on a lower cabinet and limits the position of the transformer. The inner wall of the rib 8 and the outer shape of the transformer fit together to limit the positions of right and left and front and back. On the other hand, the right and left position and the front and rear position of the transformer 9 are limited as in the case of the rib 8 by means of a transformer surrounding ribs that is provided on an upper cabinet 1 and a rib 7 that is partially provided on the inner wall of the rib 3 to fit to the transformer 9. Further, a boss 4 and a resilient protrusion 5 are provided on the upper cabinet 1 to limit the up and down position of the transformer 9. A protruding piece 5 that is provided as one body on the upper cabinet 1 absorbs the scatter of the height dimension H of the transformer 9. Namely, the protruding piece 5 has resilience in the up and down direction to keep the top face of the transformer 9 pressed by the tip end 6 of the protruding piece 5.

Description

[Detailed description of the invention] The present invention relates to a television receiver and a radio receiver.

This invention relates to a device for mounting transformers used in other antenna-related equipment to cabinets. The present invention consists of 1. Instead of using the conventional mounting method of directly screwing the transformer to the cabinet, we have integrated ribs, bosses, elastic protrusions, etc. into the cabinet to reduce the cost.
The purpose is to install the transformer with good workability and reliability.

One embodiment will be described below with reference to the accompanying drawings.

Figure 1 shows the ribs and transformer mounting part inside the upper cabinet.
Bosses, protrusions, etc. are illustrated. FIG. 2 shows the transformer inserted into the transformer position regulating rib inside the lower cabinet. FIG. 3 is a longitudinal sectional view of the upper and lower cabinets being fitted together, the transformer being inserted between the upper and lower cabinets, and the transformer being fixed. Similar to FIG. 3, FIG. 4 is a lateral cross-sectional view of the upper and lower cabinets fitted together.

The configuration will be explained in detail below. The transformer 9 is inserted into a transformer position regulating rib 8 provided integrally with the lower cabinet 2, and the inner wall of the rig 8 and the outer shape of the transformer fit together to regulate the position in the left-right and front-rear directions.

On the other hand, a transformer surrounding rib 3 provided on the upper cabinet 1 and a transformer fitting rib 7 partially provided on the inner wall of this rib 3
As in the case of the rig 8, the position of the Toyoshitrans 9 in the left, right, front and rear directions is restricted. Further, a boss 4 and an elastic protrusion 6 are provided on the upper cabinet 1 to restrict the vertical position of the transformer 9. Since the height H of the transformer 9 has large variations in dimensions, taking this variation into consideration, we installed bosses that regulate the top surface of the transformer 9 and its vertical position (
If a gap is provided between 4) (a rib may be used), it will cause looseness in the vertical direction and the transformer 9 cannot be completely fixed.
This absorbs variations in the height of the transformer 9. In other words, the angle is 66°8. . Yo Eka 1U
) K5Q1□,□, the top surface of the transformer 9 is always pressed by the tip 6 of the protruding piece 6. Therefore, even if the height of the transformer 9 varies from the minimum dimension to the maximum dimension,
The transformer 9 is always pressed by the protruding piece 6. Here, when a strong impact is applied in the vertical direction, the protruding piece 5 has elasticity, so if an excessive force is applied to the protruding piece 5, the protruding piece 5 bends greatly, and the base of the protruding piece 6 etc. Stress concentration is applied to the parts, causing damage. Therefore, a boss 4 having a gap A between the face of the transformer 90 and the boss is provided so that the projecting piece 5 is not excessively deformed. Then, the gap A is set so that there is a gap even when the height H of the transformer is at its maximum dimension. Due to the boss 4, even if the cabinet receives a strong impact, the top surface of the transformer 9 and the tip of the boss 4 will come into contact with each other, so the protruding piece 5 will not deform any further, and no transient force will be applied to the protruding piece 5. , there is no damage to the protruding piece 6.

In the example shown, the upper and lower cabinets 1 and 2 are connected by a boss 10. Mounting recess 11. This cabinet joining method □4 is performed using screws 12.

There is no particular question regarding this.

Furthermore, if the protruding piece 6 is eliminated and the boss 4 is used to constantly press the top surface of the transformer 9, the cabinet will be deformed and a gap will be created at the seam between the upper and lower cabinets, which is unfavorable in terms of appearance. In addition, in this case, by forcibly joining the cabinets, the space between the transformer 9 and the boss 4, or the boss 10. Since stress is constantly applied to the recessed portion 11, this is not preferable in terms of physical properties.

As explained above, according to the present invention, by providing the six elastic pieces and the boss with a gap between the transformer and the boss, even if the dimensions of the transformer vary when the upper and lower cabinets are fitted together, There is no rattling in the vertical direction, it is strong against shock, and the transformer can be securely fixed. Further, the left and right directions of the transformer are restricted by ribs provided on the upper and lower cabinets, but even if a slight clearance is provided, no wobbling will occur because the transformer is constantly pressed by the protruding pieces. Also, the rib 7 for fitting with the transformer may be eliminated and the rib 3 may be reduced so that the transformer and the surrounding rib 3 fit directly.
Rib 7 is installed so that the transformer and surrounding ribs fit smoothly.
By rounding the tip of the rib 7, the rib 7 also serves as a guide during insertion, so it is preferable to provide it.

Claims (1)

[Claims] A rib for regulating the position of the transformer is provided on one side of the cabinet divided into at least two parts, and a lip for regulating the position of the transformer is also provided so as to face the other cabinet, and when both cabinets are connected to each other, the top surface of the transformer is A boss or rib is provided on either one of the cabinets 7) so as to form a gap between the A transformer mounting device 0 in which a protruding piece for sandwiching the transformer is provided on the other cabinet, and the transformer is attached to the cabinet using the position regulating lip, boss, and protruding piece at the same time that both cabinets are combined.
