されている基板の接続端子とを連結するフレキシブルポ
ストに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for connecting a power supply bus plate or a grounding basic plate and connection terminals of a board on which components are mounted at high density in electronic and communication equipment. This relates to flexible posts to be connected.
高密度基板へ例えば電源を供給する場合に、基板プレー
トのハスプレートと基板の縁に設けられる接続端子との
間に導電性のポストを連結して、基板を基本プレートに
対して平行に支持し、且つ電圧ドロップが少ない状態で
給電する方式がある。For example, when supplying power to a high-density board, conductive posts are connected between the base plate of the board plate and the connection terminals provided on the edge of the board to support the board parallel to the base plate. There is a method of supplying power with less voltage drop.

ートのバスプレートとの間に多種類の電源を供給すべく
多数のポストを連結する必要がある。On the other hand, in recent years there has been a trend to reduce the number of circuit boards by configuring as many electronic circuits as possible on a single board, and as a result, the board itself has become larger and more dense, and the bus plate between the board and the basic plate has become larger. It is necessary to connect a large number of posts in order to supply various types of power between them.

ようになっている。The above-mentioned posts are basically connected by screws, and an example of this connection is shown in Fig. 3. The figure shows an exploded perspective view of the bus plate and the post connected to the board. Reference numeral 1 is the bus plate, 2 is the board, 3 is the connection terminal provided on the edge of the board 2, 4 and 5 are communication holes, and 6 is the connection terminal. It's a post. The post 6 consists of a conductive solid rod 7 cut to a predetermined length and two screws 8 and 9 that fasten it together. Then, the rod 7 is aligned and sandwiched between the communication hole 4 of the bus plate 1 and the communication hole 5 of the connection terminal 3 of the board 2, and screws 8. The posts 6 are connected by inserting the rods 9 and fastening them to both ends of the rod 7.

スト６の連結位置も連通孔４゜５により決められて自由

数も少ない場合には問題を生じない。Therefore, in the above structure, the axial direction of the post 6 is determined by the length of the rod 7 and has no degree of freedom. Further, the connecting position of the posts 6 is also determined by the communication hole 4.degree. 5, so there is no degree of freedom, but this does not cause any problem if the substrate 2 is not very large and the number of posts 6 is small.
ところで、上述するように一枚の基板２１体が大型化、

のボスト棒体７の垂直性を確保し難くなって、接触不良
、基板２のゆがみ等の不具合を生じる。By the way, as mentioned above, the size of one board 21 increases,
As density increases, a large-capacity power supply becomes necessary, but the thickness of each post and the area of the board connection terminal 3 cannot be increased too much, so the number of posts must be increased. On the other hand, there are variations in the dimensional accuracy of the thickness of each part of the large board 2, the thickness of the many connection terminals arranged on the edges on both sides, and the length of the large number of posts 6 themselves. Bus plate 1 and board 2 at the connection position
It becomes difficult to properly install the rod 7 of the post 6 between the two. The same thing can be said about the pinch dimensional accuracy of the communication hole 4.5 between the bus plate l and the board 2, making it difficult to ensure the perpendicularity of all the boss rods 7, resulting in poor contact and distortion of the board 2. This may cause other problems.
更に、この種の基板２は発熱が多くて冷却した場合でも
各部の雰囲気温度の差が比較的大きい傾向になる。一方

不具合も生じ得る。Furthermore, this type of substrate 2 generates a lot of heat, so even when it is cooled, the difference in ambient temperature between various parts tends to be relatively large. On the other hand, there are many types of power supplied by a large number of posts 6, and therefore the thermal expansion at each post 6 varies in various ways, which may cause problems such as deformation of the board 2 during use. obtain.
本発明は、上記問題点を解消した寸法精度のバラツキお

ーズを設けたフレキシブルポストによってなされる。The present invention provides a flexible post capable of absorbing variations in dimensional accuracy and various miscellaneous thermal expansions, which eliminates the above-mentioned problems. This is achieved by a flexible post in which at least a part of the connected conductive rods is provided with a conductive bellows in the form of a bellows, which can be expanded and contracted and can be freely shifted.

る。In the above flexible post, the bellows-like conductive bellows can expand and contract arbitrarily in the axial direction in response to variations in the spacing between the connection terminals on the bus plate and the board, and can freely expand and contract in the radial direction in response to variations in the pinch of the communication hole between the two. By absorbing these variations by misaligning the rods, the rods can be connected accurately at all connection positions, and various miscellaneous thermal expansions during use can be absorbed by the conductive bellows to prevent them from affecting the board. This is what I did.

ズ１２が縮んでその熱膨張を吸収する。FIG. 2 is a sectional view showing a connected state of flexible posts according to an embodiment of the present invention. In the figure, the protrusion 14 of the connecting piece 11 is inserted into the predetermined communication hole 4 of a plurality of bus plates 1 stacked on a basic earthing plate 15 via an insulating plate 16, so that the connecting piece 11 is integrally attached to the bus plate 1. Weld to. In addition, the grounding basic plate 1 is arranged so that the connecting piece 14 is directly connected to the upper bus plate 1.
5. A notch 17 is provided in the insulating plate 16 and the lower bus plate 1 layer. Attach the end of the rod 7 opposite the conductive bellows 12 to the connection terminal 3 of the board 2, aligning the communication hole 5 and the screw hole 10, and insert the screw 8 from the opposite side of the board 2 to the rod 7. The rod 7 of the flexible post 6 is thus connected between the bus plate I and the connection terminal 3 of the board 2. If there are variations in the spacing between the bus plate 1 and the board connection terminals 3 during the above connection, the conductive bellows 12 will expand or contract accordingly, and if there is variation in the pinch of the communication hole 4.5, the conductive bellows 12 will expand or contract accordingly. The conductive bellows 12 is misaligned accordingly, thereby absorbing both of these variations. Further, when the rod 7 thermally expands due to the amount of power supplied to the post itself and the ambient temperature during use in the connected state, the conductive bellows 12 contracts to absorb the thermal expansion.

され、大容量電源供給方式において有効である。As explained above, according to the present invention, variations in the dimensional accuracy of the connecting portion between the bus plate and the board connection terminal are three-dimensionally absorbed by the conductive bellows provided in the middle of the rod.
It is not necessary to extremely increase the dimensional accuracy of the connecting portion, and the connectivity is also improved, making it suitable for connecting a large number of posts to a board that is becoming larger and more dense. In addition, since thermal expansion of the rod shape is also absorbed and does not affect the substrate, deformation of the substrate is prevented, which is effective in large-capacity power supply systems.
