Abstract

PURPOSE:To rationally assemble and to prevent a malfunction from occurring by forming straight grooves on a board surface, connecting parts to be wired over the groove by jumper wires, mounting electronic components, and then bending the board at the groove. CONSTITUTION:Two grooves 2a, 3a are formed on one side surface 2a of the intermediate of a board, grooves 2b, 3b are formed at positions of rear side of the grooves 2a, 2b on the other side surface 1b, a plurality of jumper wires 4 bridging over the grooves 2a, 3a are provided, the board is bent in a U shape at the grooves 2a, 3a, 2b, 3b as references, and the wires 4 are bent at the bent grooves 2a, 3a, 2b, 3b. Thus, the board is bent to be formed in a shape adapted to mount one board in a case. Accordingly, it can be easily mounted in a small-sized case, and when electronic components 5 are mounted, since they can be mounted not on a plurality of boards but on one board, it can be rationally manufactured.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printed circuit board on which electronic components are mounted.

[Prior Art] When a large number of electronic components are mounted on a printed circuit board, the assembly is performed by a machine, but due to the dimensions and space of the case in which they are mounted, it is necessary to divide the electronic components into multiple printed circuit boards. There are many.

In this way, multiple printed circuit boards are installed inside the case with limited space. [Problem to be solved by the invention] When multiple printed circuit boards are installed inside the case in this way, the printed circuit boards must be connected to each other with lead wires, which makes assembly difficult. It had

Further, due to the nature of printed circuit boards, connecting a plurality of printed circuit boards to each other requires a large number of lead wires, and if this is done manually, it takes a long time to assemble.

In order to solve this problem, electronic components are mechanically installed on each printed circuit board and connected via plugs that are installed at the same time.

In this case, although assembly is easy, it takes time and effort to assemble the lead wires that connect the plugs to each other.Furthermore, since each product has a different circuit, the number of types of lead wires increases, and people often mistakenly Problems such as assembly of the model lead wires occurred.

Also, since it is a plug, there is a risk of poor contact.
Furthermore, as the number of lead wires increased, the plug became larger, requiring a larger space inside the case.

The present invention was made in view of these circumstances, and
The purpose of this invention is to provide a printed circuit board on which a large number of electronic components are installed, which can be assembled rationally and which does not cause defects.

[Means for Solving the Problems] The present invention forms a straight groove on the surface of the board, connects the part where wiring is to be carried across this groove with a jumper wire, and connects the board with this groove after mounting electronic components. The problem is solved by bending it.

[Operation] A board to be divided into a plurality of parts becomes one board through the groove, and electronic components can be implanted on the board to be divided into a plurality of parts at the same time.

Then, it can be bent based on the groove, and can be folded and mounted according to the space of the case.

The bendable groove is provided with a jumper wire that crosses over, so there will be no wiring problems between the printed boards.

In addition, jumper wires can be installed using the same machine as electronic components, so they can be assembled without much effort and without mistakes.

[Example] The present invention will be explained based on an example not shown in the drawings. Fig. 1 is a perspective view of a printed circuit board according to the present invention, and Fig. 2 shows the printed circuit board in a bent state. FIG. 3 is a diagram showing another embodiment.

In FIG. 1, the printed circuit board has two grooves 2a and 3a on one side 1a in the middle of the board, a groove 2a on the side 1b,
Erasers 2b and 3b are formed at positions on the back side of 3a, respectively.

A plurality of jumper wires 4 are provided across the respective grooves 2a and 3a, and a plurality of electronic components 5 are provided on one surface 1a.

Furthermore, the gaps 2a, 3a and ? v12b, 3b are each formed straight, and are configured to be able to be bent based on m2a, 2b, 3a, 3b.

In Figure 2, the printed circuit boards are erasers 2a, 3a, 2b.
, 3b are bent into a U-shape, and the jumper wire 4 is bent at the bent portions m 2 a, 3a, 2b, and 3b.

In FIG. 3, the board 6 is bent into a U-shape, and the bent part 6a is attached to the case 8 with a spacer 9.
It is fixed with a screw 1o via the screw 1o.

The other side of the board 6 is attached to the fitting part 11 of the case 8 .

In such a configuration, the printed circuit board has the electronic components 5 implanted in the state shown in FIG. Form by folding it into a U-shape.

By bending the board in this manner, a shape suitable for mounting one board in the case is obtained.

Therefore, it can be easily mounted on a small case, and when mounting the electronic component 5, it is not necessary to mount it on multiple boards.
Since it can be done on one board, it can be manufactured rationally.

Further, in the part to be bent, a jumper I14 is planted beyond the erasers 2a and 3a, and by being bent, the circuit on the board is 'iXl! 7r will not be given,
It becomes connected.

Such a bending of the board can be set at an arbitrary position, and can be shaped to suit the case 8 as in the embodiment shown in FIG.

[Effects of the Invention] According to the present invention, electronic components and jumper wires are planted on a plurality of printed circuit boards as a single board using a machine, the board is bent and formed into a shape according to the case, and the electronic parts are assembled into one board. This makes it possible to rationalize the assembly of printed circuit boards that are installed in large numbers and to obtain printed circuit boards that do not cause defects, and the effect is extremely large.
