DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector device, particularly to a connector device used for a portable personal computer or the like.

[0002]

2. Description of the Related Art In portable personal computers and the like, various input / output connector devices are provided so that they can be connected to external peripheral devices as required. As such a device, there is a connect device for an RS232C boat, and by using this to connect a modem device or the like, data communication becomes possible even when going out. As a technique for easily attaching and detaching and preventing reverse coupling, there is, for example, a technique disclosed in Japanese Patent Application Laid-Open No. 7-6817.

FIG. 2 is a perspective view showing a first conventional example.
In the connector device shown in FIG. 2, the first connecting portion 111 having a plurality of contacts formed thereon and the second connecting portion 112 having a plurality of contacts formed corresponding to the first connecting portion 111 have a magnet attraction force. The connection is facilitated by attachment and detachment. Also, the first connecting unit 11
By setting the polarity of the magnet so that an attractive force is generated between the first connect part 111 and the second connect part 112 only when the first and second connect parts 112 face each other, reverse coupling of the connectors is prevented. .

[0004] The contacts P1 to P24 are themselves magnetizers and are metal-plated to reduce the electric resistance. Contacts P1 and P24 of first connect portion 111
Is magnetized to S polarity, and the contacts P12 and P13 are magnetized to N polarity. Contacts P1, P2 of second connect portion 112
4 is magnetized to N polarity, and the contacts P12 and P13 are magnetized to S polarity.

The first connect unit 111 is connected to the second connect unit 1
By approaching 12, the magnet can be easily coupled by the attractive force of the magnet, and the coupling can be easily released by an appropriate external force.

If the second connect portion 112 is rotated by 180 degrees to be coupled to the first connect portion 111, the opposite magnets have the same polarity.
By generating a repulsive force between them, reverse connection of the connector device is prevented. Further, at the time of the connection operation, the above-mentioned repulsive force is felt by the hand gripping the second connect portion 112, so that the operator can immediately notice an error in the connection direction of the connector device.

When the operator notices an error in the connection direction, the operator must rotate the second connect portion 112 so as to be in the normal direction with a force necessary to cancel the twisting resistance of the cable 113. If the contacts P1 to P24 of the portion 112 are rotatable, the polarity can be automatically matched (for example, see Japanese Patent Application Laid-Open No. 4-296475).

FIG. 3 is a sectional view showing a second conventional example.
In the connector device shown in FIG. 2, a connector 202 having a permanent magnet 208 in a guide cylinder 205 and electrode terminals 206 and 207 having a plurality of polarities arranged so as to protrude from the permanent magnet 208 is used as a fixing portion. . This electrode terminal 20
6, permanent magnets 222 are formed at positions where they can be brought into contact with each other and can form a magnetic path integral with the permanent magnet 208. The permanent magnets 222 correspond to the electrode terminals 218, 219. The moving device is provided with a connector 203 in which a shaft 216 having insulating members 217 and 221 formed therein is rotatably supported by bearings 214 and 215.

[0009]

In the conventional connector device described above, since the conductor on the plug side is simply pressed against the conductor on the plug seat side, an oxide film grows on the conductor, or However, when an insulating material is adhered to the substrate, good contact cannot be obtained.

[0010]

According to a first aspect of the present invention, there is provided a connector device comprising a plurality of first conductor portions provided on a slope of a truncated cone-shaped insulating portion and a tip portion of the truncated cone-shaped insulating portion. A plug having a plurality of first permanent magnets, and a position capable of contacting the plurality of first conductor portions on the inner wall slope of the concave insulating portion having a shape for receiving the truncated conical insulating portion. A plurality of arranged second conductors and a plurality of second permanent magnets provided at the bottom of the concave insulating portion and arranged so as to form a magnetic path integral with the first permanent magnet; Plug seat 14 with
It is comprised including.

The connector device according to a second aspect of the present invention is the connector device according to the first aspect, wherein a difference is provided between the inclination angle of the concave insulating portion with respect to the inclination angle of the truncated conical insulating portion, and the plug is connected to the connector. At the time of insertion into the plug seat, the plurality of first conductors enter while sliding on the plurality of second conductors, so that the contact surfaces of the respective conductors are cleaned while the two first conductors are cleaned. To keep in contact.

[0012]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention. The connector device shown in FIG.
5, a plurality of conductors 1a, 2a, 3a,.
And permanent magnet 1 provided at tip 3 of insulating portion 15 having a truncated cone shape
