Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply/distribution bus mounted on a circuit board, and more particularly to a power supply/distribution bus having a structure in which the power supply/distribution buses can be freely combined and connected to each other.

This type of power supply/distribution bus bar, which is used to supply high-quality power to electronic components such as integrated circuit elements mounted on a circuit board, is made of two long and thin sheets made of materials such as copper plates, as shown in Figure 1. The conductive plates 1 and 2 are laminated with a suitable insulating member or a dielectric member 3 having a high permittivity such as a thin ceramic plate interposed therebetween, and the conductive plates 1 and 2 are laminated at required intervals on the sides in the longitudinal direction. A protruding terminal IA.

All but two people have a structure in which this laminate is covered with an insulating exterior part 4. Such conventional power supply and distribution busbars are designed and manufactured each time to a size that conforms to the specifications, such as matching the shape of the circuit board or chassis or frame of the device to be mounted, and the position of the electronic components to be mounted. There was a need. Therefore, for example, when a large number of power supply and distribution buses of this type are mounted on a circuit board, power supply and distribution buses of various shapes must be manufactured accordingly, and product standardization is extremely difficult. On the other hand, in order to mount a large number of power supply and distribution buses on a circuit board, the number of power supply wiring patterns that must be formed on the circuit board side will increase accordingly, and this will require high-density mounting of electronic components on the circuit board. This is not desirable as it may cause problems.

In consideration of the above-mentioned circumstances, the present invention reduces the number of power supply wiring patterns to be formed on circuit boards etc. to the necessary minimum by configuring this type of power supply/distribution busbars so that they can be connected to each other in arbitrary combinations. The present invention provides a new power supply/distribution bus that effectively promotes high-density packaging and also achieves standardization of the power supply/distribution bus itself as much as possible.

The power supply and distribution busbar according to the present invention is characterized in that it is provided with connection parts that can be electrically connected to each other. Therefore, several basic types are manufactured and these can be arbitrarily combined and connected. By doing so, it is possible not only to construct a power supply/distribution bus bar having a desired length, but also to easily construct one in a T-shape, H-shape, chamber shape, or the like, which is most suitable for a circuit board.

Hereinafter, the present invention will be described in detail with reference to the drawings showing preferred embodiments. In FIGS. 2 and 3, 5 and 6 are elongated conductive plates such as copper plates similar to those described above,
Terminals 5A as described above are provided on each side in the longitudinal direction.

A required number of 6A protrusions are formed. 7 is both groove body plates 5, 6
An insulating member or a dielectric member with a high permittivity such as a ceramic plate is interposed between the two groove plates 5 and 6. A power supply and distribution bus can be configured. Reference numeral 8 denotes an insulating exterior portion provided except for each terminal 5A, 6A. As shown in the figure, the power supply and distribution busbar according to the present invention has both groove plates 5 and 6 at one end or both ends thereof, and connection parts 9 and 1 for connection to the other power supply and distribution busbar.
0 are separately formed in a protruding manner, and as shown on the right side of FIG. Connecting portions 11 and 12 are formed in such a manner that a portion of each conductive plate 5, 6 is exposed. These connections 9, 10 or 11.1
2 can be configured so that the same power supply/distribution bus bar is provided with one of the types or both types. According to such a power supply/distribution bus 13, the mounting connection parts 9, 1
Exposed connection 11.1 with 0 at the end of another power distribution bus
By inserting and fitting the connectors 2 in between and connecting them, it is possible to easily increase the length of the power supply and distribution busbar. Similarly, by appropriately combining and connecting such power supply/distribution buses 13, a T-shaped power supply/distribution bus 14. The H-shaped power supply/distribution bus 15, the window-shaped power supply/distribution bus 16, etc. can be freely combined and constructed.

Spot welding, soldering, brazing, or addition of conductive or ordinary adhesive, etc. to the above-mentioned combination connection consisting of the insertion and fitting type of the mounting connection parts 9 and 10 and the exposed connection parts 11 and 12. It is possible to strengthen the connection portion by appropriately employing other connection means. In addition, the exposed conductor surfaces of both connection parts 9.10 and 11.12 in the power supply/distribution bus bar with such a structure should be subjected to anti-corrosion treatment, or if necessary, plating should be applied to these parts as appropriate. These are also matters that can be adopted in implementation, and it is also possible to protect these connection parts by pasting a removable protective sheet or the like on these connection parts by the time of mounting. Particularly in the case of a type in which the same power supply/distribution bus is provided with both the connection parts 9, 10 and 11, 12, the connection parts that are not used in the combined connection are covered with preferably an insulating protective sheet as described above. It is recommended that it be protected.

The power supply and distribution busbar according to the present invention can avoid the need to connect each individual busbar to a power supply wiring pattern of a circuit board or the like as in the past, and thus can effectively contribute to high-density packaging of circuit boards. In addition, since the power supply and distribution busbar of the present invention has a structure that can be freely combined and connected at the time of mounting, it can be mounted in the optimal form on the circuit board. This has the advantage of reducing the amount of manufacturing required and promoting product standardization.
