DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector with a circuit changeover switch, and more particularly to a portable telephone having a switch for disconnecting an antenna built in an airframe when an external antenna is connected. It is about connectors.

[0002]

2. Description of the Related Art Conventionally, an interface section of a portable telephone is composed of a power control and a high frequency signal, and a coaxial connector is used for a high frequency signal. Applications connected to the interface include a charger and an external antenna.

[0003] By the way, a mobile phone has a circuit so that the antenna built in the body operates when used alone, and when an external antenna is connected, the operation of the built-in antenna is stopped and only the external antenna operates. It is necessary to switch. That is, when an application is connected to the interface section of the mobile phone, an interface connector that incorporates a switch that switches the antenna circuit only when a coaxial connector is incorporated in the application is required.

Conventionally, as a connector having a circuit changeover switch function to meet this demand, there has been proposed a connector disclosed in Japanese Utility Model Application Laid-Open No. 60-191.
No. 65, and a coaxial receptacle connector type as shown in FIGS. 5A and 5B are known. That is, the conductor 7 having the spring property and the fixed conductor 8 are provided in the connector housing 11, and when the mating connector is not fitted, the spring conductor 7 contacts the fixed conductor 8 and is mutually connected. The conduction state is ensured. And FIG.
As shown in (a) and (b), when the coaxial plug connector, which is the mating connector, is fitted and connected, the center contact 9 of the coaxial plug connector becomes the spring conductor 7 and the fixed conductor 8.
Then, the spring conductor 7 is pushed up, the conductive connection between the spring conductor 7 and the fixed conductor 8 is released, and the circuit is switched.

Further, as a connector having this type of circuit changeover switch function, Japanese Utility Model Application Laid-Open No. Sho.
As disclosed in Japanese Unexamined Patent Publication (Kokai) No. H11-260, there is known an apparatus having a switch at a position facing a coaxial plug connector of a coaxial receptacle connector plug seat.

[0006]

In the above-mentioned conventional connector with a circuit changeover switch, the center contact 9 built in the coaxial plug connector functions as a changeover switch. As described above, in the type in which the spring-like conductor 7 is pressed against the spring by the center contact 9, a pressing force from one direction is applied to the center contact 9, and the center contact 9 is easily deformed. Become. If the center contact 9 is deformed in this way, it becomes difficult to match the impedance, causing a problem when used in a high frequency range.

Further, since two types of the spring conductor 7 and the fixed conductor 8 are accommodated in a narrow space inside the coaxial connector, even if the contacts 7 and 8 are separated at the time of connector fitting connection. In addition, the separation distance cannot be increased, and the isolation decreases.

Further, as a connector having this type of circuit changeover switch function, Japanese Unexamined Utility Model Publication No. 60-174083 has been proposed.
As shown in the publication, the coaxial receptacle connector connector
Although a switch having a switch at a position facing the coaxial plug connector of the plug seat is shown, the position of the tip of the push button of the switch fluctuates when the connector is fitted in the configuration shown in this publication, so that At the time of mating, there is a problem in that the switch does not hit the front surface of the coaxial plug connector, the switch is not pressed, and the switch is not switched.

Also, unlike the one disclosed in this publication, when the thickness of the coaxial plug connector is small and the area of the front section is small, the above problem becomes more remarkable. In addition, reliable switching cannot be performed.

Accordingly, it is an object of the present invention to provide a connector with a circuit changeover switch capable of reliably switching circuits without deteriorating the performance of the coaxial connector.

Further, in the foldable portable telephone, as shown in FIG. 7, when a switch for switching the center contact 9 incorporated in the coaxial receptacle connector is used as a high frequency signal switching means, the power provided in the upper unit 71 is increased. The high frequency signal from the amplifier 63 passes through the folding unit 72, passes through the connector 74 provided in the lower unit 73, passes through the folding unit 72 again, and is guided to the built-in antenna 64 provided in the upper unit 71.

However, according to this method, the folding section 72
Since the number of coaxial lines passing through the cable is usually two and four in the case of the diversity system shown in FIG. 7, the folding operation becomes hard, and such a configuration is not realized. Further, since the number of lines passing through the folded portion is large, there is a disadvantage that the bending life of the folded portion is shortened.

Accordingly, it is an object of the present invention to provide a portable wireless device provided with a connector which has a simple structure of the folding portion, facilitates the folding operation, and has a long life of the folding portion. .

The actuator 4 is accommodated in a groove 40 formed on the side of the coaxial receptacle connector 1 and on the fixed conductor 3 side so as to extend in the axial direction of the coaxial receptacle connector 1. The groove 40 b of the side surface of the three-way
One side of the insulator 10 is defined by the coaxial receptacle connector 1, and the actuator 4 is accommodated in the groove 40 so as to contact the outer wall of the external contact 13.

The distal end of the spring conductor 2 is formed so as to extend to a position above the upper end surface of the actuator 4.

Next, a coaxial plug connector 5 as a mating connector is fitted and connected to the coaxial receptacle connector 1, and
The case where the connection between the spring-like conductor 2 and the fixed conductor 3 is disconnected will be described.

When the coaxial receptacle connector 1 is fitted into the coaxial plug connector 5 from the state shown in FIG. 2A, the external contact 51 of the coaxial plug connector 5 comes into contact with the lower end of the actuator 4, and as shown in FIG. As described above, the actuator 4 is pushed up. At this time, the distal end surface of the actuator 4 engages with the end of the spring conductor 2 located above, and lifts this end to release the contact with the fixed conductor 3.

In the above configuration, since the spring conductor 2 and the fixed conductor 3 are exposed outside the connector, the distance between the spring conductor 2 and the fixed conductor 3 can be increased. The presence or absence of the connection of the coaxial plug connector 5 can be easily confirmed from the outside.
