Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a connector device that connects a thrust-side member to a receiving-side member by abutting against each other to obtain electrical connection.

(Prior Art) Conventionally, electrical circuit connector devices have various shapes depending on the purpose. Most of these connector devices move with the contacts of the thrusting side and receiving side members in contact with each other during the connection, which transitions from the pre-connection state shown in Figure 1 to the post-connection state shown in Figure 2. Therefore, due to the frictional force caused by the contact between the contacts, a considerable amount of force is required to insert and remove the connector, which may cause damage to the cases of the plunger side member, the receiving side member, and the electrical parts connected to them. was. Furthermore, since the surfaces of the contacts are scraped together while moving in contact with each other, repeated insertion and removal many times may result in poor electrical contact. In order to eliminate this drawback, connector devices that require insertion durability have adopted a method in which the contacts are butted against each other, as shown in Figure 6, but this Qib connector device uses some method to connect the contacts. For this purpose, you can insert a wedge-shaped object between the two, tighten the connector case with a screw, or use a spring-like part, the connector case, or a part of the device connected to the connector. They were holding me down.

However, this takes time to insert and remove, which is a serious drawback for this type of connector device, which requires frequent insertion and removal.

(Objective) The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a connector device that has excellent insertion/extraction durability and also has excellent insertion/extraction operability.

(First Embodiment) FIG. 4 shows a first embodiment of the present invention, in which a receiving connector body 6 for configuring a connector device is integrated into an exterior case 2 of an electronic device 1 such as an electronic typewriter. Fixed. On the other hand, a thrust-side connector body 4 is in abutting relationship with the receiving-side connector body 3 and is removably connected thereto. An electrode 5 having a contact portion 5A protruding forward is built into the plug-in connector body 4. A lead wire 6 is connected to the rear end of this electrode 5, and this lead wire is connected to another electric circuit. Inside the connector body 4 on the protrusion side, a permanent magnet 7 having a substantially U-shape and a pyramid-shaped protrusion 7A at the tip thereof is fixed such that both protrusions 7A protrude from the end surface of the body 4. .

Further, within the receiving connector body 6, an electrode 8 is fixed, with a contact 8A protruding from the end surface of the body 6, which contacts the contact 5A of the plunger connector body 4. The rear end of this electrode 8 is connected to a printed circuit board 9 that is integrally fixed to the case 2 of the electronic device 1 .

Furthermore, the receiving side connector body 6 has a magnetic pole arrangement that is in an attractive relationship with the permanent magnet 7 inside the thrusting side connector body 4,
and four parts 10 that fit into the pyramidal protrusion 7A of the permanent magnet 7.
A substantially U-shaped permanent magnet 10 having a letter A is fixed. In this way, the respective permanent magnets 7 and 10 in the plunger side and receiving side connector bodies, due to the force of the magnetic stage 1,
Both bodies 3゜4 are connected, and the protruding part 7A and the fourth part 10 are connected.
By fitting A, the contacts 5A and 8A are maintained in a secure state of contact with each other without causing any positional deviation.

On the other hand, the central part G of the permanent magnet 1o of the receiving side funecta body B
A solenoid 11 for disconnecting the connector is wound around C. A voltage from a power source 12 is selectively applied to this solenoid 11 by a disconnection switch 16 . When the solenoid 11 is energized, it generates a magnetic field which weakens the magnetic force of the permanent magnet 10, so that both connector bodies 6.4 can be easily separated. Note that the power source 12 and the disconnection switch 16 may be incorporated into the case 2 of the electronic device.

As described above, according to this embodiment, the thrust-side connector body 4 and the receiving-side connector body 6 can be easily connected and disconnected according to the operation of the switch 16, and the operability is greatly improved.

Furthermore, since the contacts 5A and 8A make butt contact without sliding, there is no wear on the contacts.

(Second Embodiment) FIG. 5 shows a second embodiment, in which a receiving connector body 16 is integrally fixed to an exterior case 15 of an electronic device 14. Inside the receiving connector body 16, there is a contact 17A.
An electrode 17 protruding from the end surface of the body 16 is fixed, and the rear end of the electrode 17 is connected to a printed circuit board 1B fixed to the outer case 15. A solenoid 19 having a coil wound thereon is fixed to the center of the receiving connector body 16. A voltage from a power source 21 is selectively applied to this solenoid 19 via a switch 2D.

A thrust-side connector body 22 is arranged opposite to the receiving-side connector body 16. Plunging side connector body 22
Inside is contained an electrode having contacts 28A (FIG. 6) that respectively contact the contacts 17A of the receiving connector body, and these electrodes are connected to each other via a flexible cable 26.
It is also connected to an external device (not shown). A pair of connecting claws 26 and 27, each made of a permanent magnet, are rotatably supported on both side surfaces of the plunger-side connector body 22 around shafts 24 and 25, respectively. The pair of connecting claws 26 and 27 are formed with claw parts 26A and 27A for locking the end face of the receiving connector body 16, respectively, and furthermore, the claw parts 26A and 27A are formed at positions where they contact the end face of the solenoid 19 so as to have different polarities. A magnetic pole is formed. Therefore, when the insertion side connector body 22 is moved in the insertion direction, the connecting claws 26, 27 first contact the receiving side connector body 16 with their tip slopes 26B, 27B and open as shown by the dotted lines, and then the connecting claws The receiving connector body 16 is held by the magnetic force as shown in FIG. In this state, the contact point 17A of the receiving side connector body 16 and the contact point 28A of the thrusting side connector body 22 are brought into good contact and an electrical connection is obtained. To release the connection between the push-in and receiving-side connector bodies 22 and 16, turn the switch 2D ON, and the solenoid 19 will not generate a magnetic field of opposite polarity to the connecting claws 26 and 27, but by the magnetic repulsion of both. Connecting claw 26.27
is rotated to the position shown by the dotted line in FIG. 5 to release the engagement.

According to this embodiment, the same effects as in the first embodiment can be achieved, but a stronger connection can be obtained due to the mechanical coupling force of the connecting claws 26 and 27.

(Sixth Embodiment) FIG. 7 shows a sixth embodiment of the present invention, in which a printed circuit board 29, which is a plug-in connector body, has a casing around it to constitute, for example, a ROM cartridge, and an end portion thereof The contacts 30 for connection are printed.
