Description

[Detailed description of the invention] [Industrial application field]

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 that allows the power supply/distribution buses to be freely combined and connected to each other.

[Conventional technology]

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 conductor plates 1 and 2 are laminated and formed with a suitable insulating member or a dielectric member 3 having a high permittivity such as a thin ceramic plate interposed therebetween, and the conductor plates 1 and 2 are laminated at required intervals on the sides in the longitudinal direction. It has a structure in which this laminate is covered with an insulating exterior part 4 except for the protruding terminals 1A and 2A.

[Problem to be solved by the invention]

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 chassis or frame of the circuit board or equipment to be mounted, and the position of the electronic components to be mounted. The need arose. 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 must be manufactured in various shapes accordingly, making product standardization extremely difficult. On the other hand, in order to mount a large number of power supply and distribution busbars on a circuit board, the number of power supply wiring patterns that must be formed on the circuit board side will increase accordingly, but this will cause the number of electronic components on the circuit board to increase accordingly. This is undesirable because it causes problems in high-density packaging.

[Means to solve the problem]

In view of the above circumstances, the present invention has been developed to reduce the number of power supply wiring patterns to be formed on a circuit board etc. to the necessary minimum by configuring this type of power supply and 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 of components and also achieves standardization of the power supply/distribution bus itself as much as possible. The power supply/distribution bus according to the present invention is characterized in that it is provided with connection parts that can be electrically connected to each other, and therefore, several basic types are manufactured and these can be arbitrarily selected. By connecting them in combination, it is possible not only to construct a power supply/distribution bus of a desired length, but also to easily construct a T-shaped, H-shaped, window-shaped, etc. shape that is most suitable for a circuit board. For this purpose, in the power supply and distribution busbar according to the present invention, a conductor plate having a plurality of terminals protruding from the sides at a required interval in the longitudinal direction is laminated with an insulating member or a dielectric member interposed therebetween, and the terminals are removed from each other. In a power supply/distribution bus for a circuit board, the conductor plate is provided with a mounting connection portion formed protrudingly at the end in the longitudinal direction, and the above-mentioned conductor plate is provided with a mounting connection portion formed protrudingly from the end portion in the longitudinal direction, and the above-mentioned conductor plate is provided with a connecting portion for mounting on another power supply/distribution bus. In order to insert and fit the connecting portion, an exposed connecting portion is formed in a part of the conductor plate.

【Example】

Hereinafter, the present invention will be described in detail with reference to drawings showing preferred embodiments. In FIGS. 2 and 3, numerals 5 and 6 are elongated conductive plates such as copper plates similar to those described above; A required number of terminals 5A, 6A as described above are formed protruding from each side in the longitudinal direction. 7 indicates that the insulating member interposed between both conductor plates 5 and 6 is a dielectric member with a high dielectric constant such as a ceramic plate, and when a dielectric member is used, it is interposed between both conductor plates 5 and 6. It is possible to construct a power supply/distribution bus with a large capacitance. 8 is each terminal 5A,
This is an insulating exterior part provided except for 6A. The power supply/distribution bus according to the present invention is characterized in that, as shown in the figure, attachment connecting portions 9, 10 for connecting to the other power supply/distribution bus are separately protruded from both conductor plates 5, 6 and integrally at one end or both ends of the power supply/distribution bus. As shown on the right side of Fig. 2, a part of the exterior part 8 is removed to expose a part of each conductor plate 5, 6 for other power supply/distribution bus bars to be connected to this. The connecting portions 11 and 12 are formed in such a manner. The mounting connection parts 9, 10 or the exposed connection parts 11, 12 can be configured so that the same power supply/distribution bus bar is provided with one type or both. According to such a power supply/distribution bus 13, the connection parts 9, 10 for attachment are inserted and fitted to sandwich the exposed connection parts 11, 12 provided at the ends of other power supply/distribution buss, and thereby the power supply is connected. It becomes possible to easily increase the length of the power distribution bus. Similarly, by appropriately combining and connecting such power supply/distribution buses 13,
The T-shaped power supply/distribution bus 14, the H-shaped power supply/distribution bus 15, the window-shaped power supply/distribution bus 16, etc. as illustrated in FIGS. 1 to 3 can be freely combined and configured. Mounting connection parts 9, 10 and exposed connection parts 11, 12
For the above-mentioned combination connections consisting of insertion-fitting types with etc. are optional. 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 rust prevention treatment, or if necessary, plating treatment 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. In particular, in the case of a type in which the same power supply/distribution bus bar is provided with both mounting connection parts 9, 10 and exposed connection parts 11, 12, the connection parts that are not used in the combination connection are preferably It is preferable to protect it with an insulating protective sheet or the like.

【Effect of the invention】

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. Furthermore, the power supply/distribution bus of the present invention has a structure having a mounting connection part and an exposed connection part that can be freely combined and connected to each other during mounting, so that it can be mounted in an optimal form on a circuit board. can. Furthermore, there are advantages such as the need to design and manufacture each case according to specifications as in the past, and promote product standardization.
