High-frequency apparatus

Abstract

The invention provides an inexpensive high frequency apparatus having good productivity, wherein a circuit board can be miniaturized. This high frequency apparatus is equipped with a box-shaped frame 1 of a metal plate, a coaxial connector 3 mounted to the front plate 1a of the frame 1, and a circuit board 10 to which the coaxial connector 3 is connected and which is mounted in the frame 1. Since the circuit board 10 located in the frame 1 and the coaxial connector 3 are formed so that the circuit board 10 is located in a deleted part 7a which is an escape part provided in the mounting part 7 of the coaxial connector 3, a cut part provided in a conventional circuit board is not required, and accordingly the area of the circuit board 10 can be enlarged. Since the degree of crowdedness of wiring patterns 11 can be not only heightened, but also the cut part is not required in the circuit board 10, the inexpensive high frequency apparatus having good productivity 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 the interval configuration, is arranged on 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 ce...

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.
