Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is implemented on a bus line device, for example, an electronic circuit board, and connects each device on the board with +,
- Regarding the so-called minibus line device used for the purpose of stably supplying power to the device, it is particularly equipped with an electrically shielded signal line so that this signal line can be used as a signal line for the board circuit. This is what I did.

Generally, on a printed circuit board, the signal lines used in the circuit board are also printed, but the signal lines printed on these boards are usually not subjected to any shielding (electrical shielding) treatment. . Therefore, there is a serious problem in that external noise or unnecessary radiation enters through this signal line, causing noise to be generated in the board circuit and having an adverse effect. For this reason, it has been difficult to take countermeasures against this noise in the past. For example, one of the countermeasures is to house the board itself in a shield box, but this method However, the disadvantages were that the equipment became larger and the price of the equipment also increased.

Furthermore, in the case of printed circuit boards, there is a problem in that the printed wiring of signal lines significantly reduces the mounting density of components.

In view of such conventional problems, the present invention provides a bus line device mounted on a board for the purpose of stably supplying + and - power to devices on the board, including an electrically shielded signal line. It is an object of the present invention to provide a bus line device with a signal line that can prevent noise generation in the board circuit and at the same time improve component mounting density on the board by using it as a signal line of the board circuit.

An embodiment of the apparatus of the present invention will be described below based on the drawings.

FIG. 1 is an external perspective view of a bus line device with signal lines according to the present invention, and FIG. 2 is an exploded perspective view of the device. In the figure, M1 and M2 represent conductive metal plates, each of which is formed into a band shape as shown in the figure, and a plurality of pins P are alternately formed protruding from the lower side of each plate. These pins P are for soldering to a predetermined wiring pattern on the circuit board.

Z is an insulating layer interposed between the conductive metal plates M1 and M2. As shown in FIG. 2, this insulating layer consists of two insulating plates Z1 and Z2, and these are formed into strips having approximately the same shape and size as the above-mentioned conductive metal plates M1 and M2.

Furthermore, a plurality of signal lines S are printed at predetermined intervals on the inside of one of the insulating plates Z2, and both ends of each signal line S are connected to conductive lines protruding from the lower side of the insulating plate Z2. sex pin SP
It is connected to the.

Then, these conductive metal plates M1, M2 and insulating plates Z1, Z2 are first attached to the insulating plate Z1 with an adhesive or the like with the printed wiring surface of the signal line S inside.
and Z2 are superimposed and fixed together, and then conductive metal plates M1 and M2 are superimposed on top of them as shown in the figure and are integrally fixed.

According to this configuration, by soldering the pin P to each wiring pattern, +,
In addition, by connecting the pin SP to the wiring pattern on the board as appropriate, the signal line S placed between the two insulating plates Z1 and Z2 can be connected to the board circuit. Can be used as a signal line. Therefore, the printed wiring pattern of the signal line can be eliminated from the board, and furthermore, the signal line S completely shielded by the insulating plates Z1 and Z2 of the bus line device can be used as the signal line.

As explained above in detail, the bus line device with signal line according to the present invention is provided with an electrically shielded signal line and can be used as a signal line of the board circuit. Signal lines can be deleted. Therefore, the space on the board is expanded, and the mounting density of components can be increased.

Furthermore, since the completely shielded signal line of the bus line device can be used as the signal line, external noise and unnecessary radiation can be completely prevented, and there is no need for a conventional shield box. , it is possible to solve the problems of conventional printed wiring boards. Furthermore, it can also be used in place of the jumper wires normally used on circuit boards.
