Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a printed circuit board, and more particularly to a printed circuit board with a pin board, which is comprised of a fixing plate on which a plurality of jacks having terminals to be inserted into through holes thereof are protruded.

Conventional Technology Regarding the production of a printed circuit board with a two-circuit pin board using a combination of commercially available pins and jacks, conventionally, as shown in FIG. The terminals 3 of each jack 2 can be inserted into each through hole of a printed circuit board 4. As shown in FIG. 5, the jack 2 includes a jack body 2b provided with a threaded portion 2a.
A nut 2c is screwed into the terminal, and a split cylindrical terminal 3 is formed at one end, and a pin insertion portion 2d is formed at the other end.

The pin 5 to be inserted into the jack 2 is inserted into the pin insertion portion 2d of the jack 2, as shown in FIG.
It includes a contact 5a to be inserted into the terminal and a grip 5b.

Problems to be Solved by the Invention According to the above-mentioned conventional technology, a large number of jacks 2 pass through the fixing plate 1 and their bases are tightened and fixed by the nuts 2c. Due to errors, the jack 2 cannot necessarily be fixed to the fixing plate 1 with high precision, and due to processing errors in the through holes of the printed circuit board 4, each terminal 3 is attached to the printed circuit board 4.
cannot be inserted properly into each through-hole. Therefore, it may become impossible to mount a two-circuit pin board. Further, even if the pin 5 is successfully mounted, when the pin 5 is inserted into the pin insertion portion 2d of the jack 2, the adjacent pins may be inserted at an angle so that they interfere with each other.

Means and Effects for Solving the Problems In order to solve the above-mentioned problems, the present invention has a large number of jacks installed in loose engagement with a fixing plate, and a jack holding plate is installed at the base of the jacks. A printed circuit board with a pin board was constructed by backing the fixing plate and adhering it closely, and further interposing a spacer between the jack holding plate and the printed circuit board.

If such a method is adopted, the jack is swingably attached and fixed to the fixed plate, and the terminal can be rotated 360 degrees, which absorbs through-hole machining errors and jack mounting errors, making it easier to mount the jack on the printed circuit board. In addition to being easier, the pins can be inserted without interfering with each other.

Embodiment An embodiment of the present invention will be specifically described below based on the drawings. Figure 1 is a side view corresponding to Figure 4;
FIG. 2 is a partially enlarged sectional view of FIG. 1, and FIG. 3 is a front view of the fixing plate, where the same reference numerals indicate the same parts.
The redundant explanation will be omitted.

The jack 2 is loosely fitted into a jack insertion hole 6 of a slightly large diameter drilled in the fixed plate 1. The jack insertion hole 6 has a large diameter portion 6a into which a ring 2e screwed into the jack 2 is embedded. And jack 2
The ring 2e is fixed and prevented from coming off by a restraining plate 7. The restraining plate 7 is bonded and fixed to the fixed plate 1 so as not to be easily peeled off. Furthermore, fixing plate 1
A spacer 8 is interposed between the printed circuit board 4 and the printed circuit board 4. This spacer 8 maintains a constant distance between the fixed plate 1 and the printed circuit board 4 when the terminal 3 of the jack 2 is inserted into the through hole of the printed circuit board 4, and is perpendicular to the fixed plate 1 or the printed circuit board 4. It is fixed.

According to this configuration, since the jack 2 is loosely fitted into the jack insertion hole 6, the terminal portion 3 of the jack 2 is movable as if rotating on a constant circumference, and there is no through-hole within that range. Even if the axes of the two sides are different when facing the hole, the dimensions will be absorbed,
Unreasonable mounting between the fixed plate 1 and the printed circuit board 4 can be prevented. Moreover, when the terminal 3 of the jack 2 is mounted on the printed circuit board 4, the spacer 8 applies a reaction force against the insertion force of the pin 2, and the terminal 3 of the jack 2 is inserted into the through hole of the printed circuit board 4 more than necessary. is prevented. Furthermore, even when pulling out the pin 5 from the jack 2, the force is applied to the printed circuit board 4.
This can be done without giving it directly.

Effects of the invention According to the invention described above, since the jack is loosely engaged with the fixed plate, the terminals of the jack can swing in all directions, absorbing the machining errors of the fixed plate and the printed circuit board. In addition to making mounting simple and quick, it also ensures smooth mounting of both and prevents pins from interfering with each other. Also, since a spacer is interposed between the fixing plate and the printed circuit board, it is easy to insert and remove the pins into the jack. When doing so, it has the advantage of not applying that force to the jack and not applying unreasonable force to the terminal.
Furthermore, since the jack insertion hole is loosely engaged with the fixing plate, the work of attaching the jack to the fixing plate is simple and quick, and there is no need for tools to keep the terminals in the same direction, making it more efficient. There are some effects.
