High-frequency apparatus

Abstract

Provided is a high-frequency device that achieves miniaturization of a circuit board while being highly productive and inexpensive. This high-frequency equipment includes a box-shaped frame (1) formed of metal plates, a coaxial connector (3) mounted on the front panel (1a) of the frame (1), and a (3), the circuit substrate (10) installed in the frame body (1), the circuit substrate (10) and the coaxial connector (3) located in the frame body (1), make the circuit substrate (10) in the setting In the cut-out part (7a) of the installation part (7) of the coaxial connector (3) as the avoiding part, therefore, there is no cutout part provided on the circuit board in the prior art, thereby, not only the circuit can be enlarged The area of ​​the substrate (10) can be reduced, the density of the wiring pattern (11) can be increased, and the circuit substrate (10) does not require a cutout, so that a product with high productivity and low cost can be obtained.

Description

technical field [0001] The invention relates to a high-frequency equipment suitable for TV tuners and the like. Background technique [0002] Drawings illustrating conventional high-frequency equipment, Figure 8 is a side view of an existing high-frequency device, Figure 9 yes Figure 8 A sectional view of line 9-9, below, according to Figure 8 , Figure 9 Describe the structure of existing high-frequency equipment, then the frame body 51 that is made of metal plate has the box shape that forms " mouth " shape as a whole, has the front and rear panels 51a, 51b that are rectangular, spaced apart from each other. The upper and lower panels 51c, 51d between the front and rear panels 51a, 51b, the accommodating portion 51e surrounded by the front and rear panels 51a, 51b and the upper and lower panels 51c, 51d, the hole 51f provided on the front panel 51a . [0003] The F-type coaxial connector 52 has a cylindrical outer conductor 53 and a central conductor 58 arranged in ...

AI Technical Summary

Problems solved by technology

[0011] Existing high-frequency equipment, the problem that exists is in order to avoid the installation part 56 that is fixed on the front panel 51a, cutout part 59a is set on the circuit board 59, thereby, this cutout part 59a part makes circuit board 59 area reduce, The density of the wiring pattern 60 is reduced, and the circuit board 59 must be enlarged. At the same time, the process of providing the notch 59a is required, and the productivity is deteriorated.

[0012] In addition, there is a problem that it is necessary to process the bent portion 58a on the central conductor 58, and at the same time, the bent portion 58a must be inserted through the hole 59b of the circuit board 59, thereby degrading productivity and increasing the cost.
