  The present invention relates to a circuit configuration conversion device using a coaxial connector with a switch in which when a coaxial connector plug is inserted into a coaxial connector receptacle, a movable terminal is pushed by a center contact and an electrical contact with a fixed terminal is released. is there.

  Conventionally, as a circuit configuration conversion device using this type of coaxial connector with a switch, for example, there is a high frequency switching device for board mounting disclosed in Patent Document 1.

  In this high-frequency switch, when the coaxial connector / plug is not inserted into the coaxial connector / receptacle, the contact portion of the switching spring of the coaxial connector / receptacle is in contact with the contact portion of the connecting plate, A signal is transmitted from the conductor to the other signal conductor through the switching spring portion and the connecting plate portion. For this reason, the signal output from the high frequency circuit module mounted on the circuit board is transmitted to the antenna through the high frequency switch. On the other hand, when the coaxial connector / plug is inserted into the coaxial connector / receptacle, the outer conductor of the coaxial connector / plug contacts the ground conductor of the coaxial connector / receptacle, and at the same time, the central conductor of the coaxial connector / plug contacts the switching spring. And push it down against the spring force.

  However, the high-frequency switch disclosed in the above-mentioned conventional patent document 1 has only the switching function described above, which is to transmit a signal output from the high-frequency circuit module to the antenna or to the measuring device. For this reason, the conventional high-frequency switch using the coaxial connector with a switch cannot be used for purposes other than selecting an antenna or a measuring device alternatively, and lacks convenience.

The present invention has been made to solve such problems,
A first circuit board on which coaxial connector plugs including a center contact and an outer conductor are mounted at a predetermined interval, and a first circuit is formed between the center contacts;
A fixed terminal and a movable terminal that is in electrical contact with the fixed terminal and an external terminal are provided.When a coaxial connector plug is inserted, the movable terminal is pushed by the center contact to release electrical contact with the fixed terminal, and the external terminal A circuit configuration conversion device was configured from a second circuit board in which coaxial connectors and receptacles that were in electrical contact with the outer conductor were mounted at predetermined intervals and the fixed terminals were electrically connected to each other.

  According to this configuration, each coaxial connector plug mounted on the first circuit board with the same predetermined interval is inserted into each coaxial connector receptacle mounted on the second circuit board with a predetermined gap. Then, the movable terminal of each coaxial connector / receptacle is pushed by the center contact of each coaxial connector / plug, and each movable terminal is released from electrical contact with each fixed terminal and brought into electrical contact with each central contact. For this reason, the first circuit formed on the first circuit board is interposed between the movable terminals of the coaxial connectors and receptacles. Therefore, a signal input from the movable terminal of one coaxial connector receptacle is given to the first circuit through the center contact of one coaxial connector plug, and passes through the center contact of the other coaxial connector plug. Output from the movable terminal of the other coaxial connector / receptacle. Therefore, it is possible to add the first circuit formed on the first circuit board to the circuit formed on the second circuit board including the coaxial connector / receptacle. As a result, a circuit configuration conversion device having a new circuit conversion function that has never been provided is provided using a coaxial connector with a switch, and convenience is improved.

When the coaxial connector plug is inserted, the first circuit formed on the other first circuit board is connected in series with the first circuit formed on the first circuit board. For this reason, each coaxial connector plug mounted on the first circuit board is inserted into each coaxial connector receptacle mounted on the second circuit board, and each coaxial connector mounted on the first circuit board. When each coaxial connector plug mounted on another first circuit board is inserted into the receptacle, the first circuit formed on the first circuit board is connected to the circuit configured on the second circuit board, And it becomes possible to add the 1st circuit formed in another 1st circuit board in series. Here, when the third circuit is formed instead of the first circuit on another first circuit board, the circuit formed on the second circuit board is formed on the first circuit board. A first circuit and a third circuit formed on another first circuit board can be added in series.

  With this configuration, each coaxial connector receptacle mounted on the other first circuit board with a predetermined interval is further provided with the same predetermined interval on the second other first circuit board having the same configuration. When each of the coaxial connector plugs mounted in this way is inserted, it is formed on the second different first circuit board in series with the first circuit or the third circuit formed on the different first circuit board. The first circuit thus connected is connected. Here, if the fourth circuit is formed instead of the first circuit on the second different first circuit board, the circuit configured on the second circuit board is changed to the first circuit board. A first circuit formed, a first circuit or a third circuit formed on another first circuit board, and a first circuit formed on a second other first circuit board or A fourth circuit can be added in series.

  Similarly, by additionally connecting another first circuit board, a desired circuit can be further added to the circuit configured on the second circuit board. Thus, by making the first circuit board into a so-called nested structure, it becomes possible to incorporate a circuit having a complicated configuration by the circuit configured on the second circuit board.

  Further, the present invention is characterized in that coaxial connectors and receptacles are integrated with a predetermined interval.

  According to this configuration, since a plurality of coaxial connectors / receptacles are integrated, mounting / assembling of the coaxial connector / receptacle to the circuit board is improved, and the mounting cost is reduced. In addition, by fixing and electrically connecting the fixed terminals of the coaxial connectors and receptacles in advance, the cause of connection failure at the time of mounting assembly is eliminated, and connection reliability is improved.

  Further, the present invention is characterized in that the second circuit board has a second circuit formed between fixed terminals.

At the same time, the movable terminal of each coaxial connector receptacle is electrically connected to both ends of the first circuit formed on the first circuit board via the center contact of each coaxial connector plug. For this reason, instead of the second circuit, the first circuit formed on the first circuit board is connected between the coaxial connectors and receptacles mounted on the second circuit board. Here, if a third circuit is formed on the first circuit board instead of the first circuit, the second circuit is connected between the coaxial connectors and receptacles mounted on the second circuit board. Instead, a third circuit can be connected. As a result, according to this configuration, the second circuit formed on the second circuit board can be changed to a desired circuit.

  According to the present invention, as described above, a circuit configuration conversion device having a new circuit conversion function that has never been provided is provided using a coaxial connector with a switch, and convenience is improved.
