Description

TECHNICAL FIELD The present invention relates to a terminal mounting structure for high-frequency equipment such as an electronic tuner.

Conventional technology and its problems Usually, in a pocket-sized or small electronic tube incorporated in a portable TV, as shown in FIGS. 4 and 5, a plurality of terminals arranged side by side in a row is used. 2 projects outward, and the antenna 2a is connected to the antenna 6 of the television 5, for example. In this case, tuner 1
As a built-in aspect of, the
As shown in FIG. 5 and FIG. 5, there are two kinds of modes, front and back. As long as the same tuner is used, in the mode of FIG. 4, the connection between the antenna 6 and the antenna terminal 2a is performed in the shortest distance without waste. In the mode of FIG. 5, since the antenna terminal 2a is located in the opposite direction, the pattern routing on the circuit board becomes long and the circuit becomes complicated.

Therefore, conventionally, the terminal arrangement shown in FIG.
As shown in FIG. 7, terminals with reverse terminal arrangement, each with 2
I was building a street tuner. However, this has a problem that the tuner side must prepare two types of terminal blocks and circuit boards corresponding to the terminal arrangement.

Therefore, in the terminal mounting structure for a high frequency device according to the present invention, (a) a plurality of terminals are provided on the terminal board, and the first ends of the terminals project from the surface of the terminal board. A terminal block arranged side by side in a row with the second end portion of the terminal protruding from the back surface of the terminal board, and (b) having a plurality of holes corresponding to the plurality of terminals and installed in a frame. (C) When the terminal block is attached to the circuit board with the second end portion inserted in the hole, the second end portion faces the opening on the back surface of the frame, and When the first end is attached while being inserted into the hole, the second end faces the surface opening of the frame.

Action In the above configuration, the plurality of terminals of the terminal block are attached to the circuit board on either the front or back surface.
That is, either the first end 16 'or the second end 16 "of the terminal is inserted into the hole in the circuit board (see FIGS. 2 and 3). The second end 16 "faces the back opening of the frame 12 when""is inserted into the hole, and the second end 16" is inserted when the first end 16 'is inserted into the hole.
16 ″ faces the surface opening of the frame 12. Therefore, as long as the terminal block is a constant terminal block, the terminal block to the circuit board is fixed even when the terminal block 14 is attached to any surface of the circuit board 13. Yes, it suffices to prepare one type of terminal block and circuit board.

EXAMPLE An example of a terminal mounting structure for a high-frequency device according to the present invention will be described below with reference to FIGS.

In FIG. 1, 10 and 11 are shield covers, 12 is a frame, 13 is a circuit board, and 14 is a terminal block.

The terminal block 14 is a terminal board 15 made of an insulating material.
A plurality of terminals 16 are press-fitted and fixed on the terminal 16. The terminals 16 are regularly arranged and the antenna terminal 16a is, for example, the one on the front side. In addition, the terminal 16 has a short upper portion and a long lower portion, and the upper portion has a first end 16 'and the lower portion has a second end.
16 ″.

The shield covers 10 and 11 and the circuit board 13 are formed with round holes 10a, 11a and 13a through which the terminals 16 are inserted.

A predetermined pattern (not shown) is formed on the front and back surfaces of the circuit board 13. The front surface in FIG. 1 is a mounting surface for components with leads such as coils, the leads of each component are inserted to the back surface side, and the back surface is for chip capacitors and the like. On the mounting surface, the back surface side is solder-dipped and the pattern, the tip of the lead of the leaded component, the electrode of the chip capacitor, etc. are soldered.

In the above configuration, as shown in FIG.
When the plurality of terminals 16 are attached so that the plurality of terminals 16 can be taken out from the back surface side of the circuit board 13, in other words, when the second end portion 16 ″ of the terminal 16 is inserted from the front surface side of the circuit board 13 into the round hole 13a, The electronic tuner having the second end 16 ″ protruding from the shield cover 11 on the back surface is manufactured. The solder dip is performed with the terminal block 14 attached, and the second end 16 ″ of the terminal 16 is also soldered to the back surface pattern of the circuit board 13 at the same time.

On the other hand, as shown in FIG. 3, when the terminal block 14 is attached so that the plurality of terminals 16 can be taken out from the front surface side of the circuit board 13, in other words, the first end 16 ′ of the terminal 16 is connected to the circuit board 13. When it is inserted into the round hole 13a from the front side of the second end 1
An electronic tuner having a 6 ″ projecting from the shield cover 10 on the surface is manufactured. The solder dip is made with the terminal block 14 attached, and the first end 16 ′ of the terminal 16 is a circuit board. Soldered to the back surface pattern of 13.

In this way, the plurality of terminals 16 of the terminal block 14 are connected to the circuit board 13
In any of the above aspects, the terminals 16 are inserted into the same circular hole 13a. For example, the antenna terminal 16a is inserted into the circular hole 13a 'on the front side in FIG. 1 and soldered. The Rukoto. Therefore, when manufacturing two types of electronic tuners with terminals 16 protruding from either the front or back surface, it is sufficient to prepare only one type of terminal block 14 and circuit board 13 having the same terminal arrangement and the same pattern.

The terminal mounting structure according to the present invention is not limited to the above embodiment, but can be variously modified within the scope of the gist.

For example, attachment pieces for attaching to a main board such as a television set may be formed in the front opening and the back opening of the frame 12. However, in this case, the shield cover
It is necessary to form a hole in 10, 11 through which the attachment piece can be inserted. Then, the mounting piece on the side not used as the mounting piece of the main board may be folded.

EFFECTS OF THE INVENTION As is clear from the above description, according to the present invention, a terminal block in which a plurality of terminals are arranged side by side on a terminal board and the terminal block so that these terminals can be taken out from either the front or back surface Since it has a circuit board that can be attached to, it is possible to manufacture high-frequency equipment such as electronic tuners with terminals protruding from both front and back surfaces simply by preparing a circuit board with the same pattern as the terminal block with the same terminal arrangement. It is possible.
