The present invention relates to an electrical connection structure and method for connecting a board and a rotary transformer board.

配備した方法とで行われることが知られている。Furthermore, the connection between the magnetic head and the external electronic circuit is made via a rotary transformer, and the electrical connection between the magnetic head and the rotary transformer is conventionally made by connecting lead wires connected to the magnetic νF board and connected to the rotary transformer board. A method of connecting lead wires to a common board, and JP-A-59-11
It is known that this is carried out by a method in which a conductive contact is supported on a holder and interposed between both substrates, as disclosed in Japanese Utility Model Application No. 9515 and Japanese Utility Model Application Publication No. 63-149409.
ところが、この従来方法の前者の共通基板を利用する方
法についてはＶＴＲのヘッド数（チャンネル数）の増加
に伴い、半田付けなど接続作業の煩雑化および実装の高
密度化に伴いスペースの制約上困難な而が生している。However, as the number of heads (number of channels) of VTRs increases, connection work such as soldering becomes more complicated, and the former method of using a common board becomes difficult due to space constraints due to higher density mounting. Something is alive.

ト作業が煩雑化するなど問題があった。On the other hand, for the latter, conventionally a conductive contact and a holder for supporting the conductive contact have been used, whereas for the former connection method, soldering has advantages such as reduction of work and ease of assembly work. However, what is the process of holding a conductive contact in a holder, how to fix the contact, and the shape of the holder? A degree design is required, and due to mounting space constraints, the strength of the holder is insufficient, the compressive load due to the contact fixing structure increases, and the resulting dimensional distortion of the cylinder unit is caused, resulting in poor contact reliability. This has the disadvantage of causing electrical contact to deteriorate over time, making it impossible to maintain stable electrical contact during long-term use.Also, since the holder is required to have a certain level of strength, the thickness of the holder body becomes thicker and the rotating transformer structure This limits the size of the gap between the head mounting structure and the head mounting structure, which reduces the degree of freedom in design and limits the miniaturization of equipment.Furthermore, as the number of heads (channels) increases, the number of conductive contacts to be installed increases. There were problems such as the increasing number of cents, which made the process of collecting cents more complicated.

It is possible to create a simple and reliable connection structure between the magnetic head board and the rotating transformer board in the R cylinder unit, and it is also possible to reduce the gap between the magnetic head base and the rotating transformer, making the cylinder unit more compact. This makes it possible to downsize the device, reduce the number of parts and reduce costs, and allows electrical connection between the magnetic head of the VTR and the rotary transformer in an extremely simple way. The connection of the rotating transformer coil wires is no different from the conventional process, and can be easily adapted to multiple channels without the need for special processes, and the only design constraint is the thickness of the intervening conductive elastic body. Because of this, it is possible to make it thinner and lighter, making it easier to downsize the whole, and it can also handle increased air density. It also greatly improves assembly workability, increases the degree of design freedom, saves materials, and uses a stacking assembly method. This has practical effects such as easy automation.
