Description

  The present invention relates to an apparatus requiring security for the purpose of secret protection, and a connector device having a lock and key function attached to the tip of a cable for accessing the apparatus.

  FIG. 5 is a perspective view showing a conventional electric vehicle charging connector, in which 50 is a cable-side connector and 60 is an automobile-side connector. Reference numeral 54 denotes a fitting portion of the cable-side connector with the automobile-side connector, which is a main body of the connector. A handle 53 is used when the connector main body 54 is inserted into the connector 60 on the automobile side, and has a mechanism pin so that it cannot be inserted unless it is rotated. A lock 51 prevents the handle 53 from rotating, and the handle 53 can be rotated only when the key 52 is inserted into the lock 51 and unlocked.

This conventional technique locks a cable for connecting a power source from an external power source at a charging stand or the like when charging a battery of an electric vehicle. This prevents unauthorized removal of the connector being charged or unauthorized connection.
The automobile-side connector 60 is provided with a pair of connection key terminals, and a spiral groove is formed on the outer peripheral surface of the connector.
On the other hand, the cable-side connector 50 connected to the charger is provided with a pair of connection male terminals inside the connector main body 54, and is inserted into and electrically connected to the connection terminal on the automobile side. It is like that.

In addition, an engagement pin (not shown) protrudes toward the inside of the handle 53 of the connector 50 on the cable side, and this constitutes a fixing mechanism in cooperation with the spiral groove of the connector 60 on the automobile side. When the handle 53 is rotated, the engaging pin is moved along the spiral groove. As a result, the entire connector 50 on the cable side is moved in the axial direction, and when the handle 53 is fully rotated, the male terminal for connection in the connector 50 on the cable side. Is fitted into the female terminal in the connector 60 on the automobile side, and is electrically connected.
A lock 51 is built in the connector 50 on the cable side, and a mechanism is built so that the handle 53 can rotate only when the lock 51 is released by the key 52.

  Also, as another conventional technique, a method of extending a deck from the building side as needed is described, but this is a problem because the structure becomes complicated and the production cost increases to avoid interference with the treatment table. is there.

In addition, since it is not necessary to place a contact in a place where the lock is easily worn, the life of the lock can be extended.

Embodiment 1 FIG.
First, a reference example related to the present invention will be described with reference to FIGS.
FIG. 1 is a cross-sectional view of a connector device as a reference example of the present invention, showing a state in which a key connector is fitted to a lock connector. FIG. 2 is a perspective view of the key connector. In the figure, reference numeral 10 denotes a lock connector provided in equipment requiring security, and a lock connector having a lock mechanism, and 30 denotes a key connector provided at the tip of a cable 31 for accessing the equipment and fitted to the lock connector 10. , 11 is a signal line (corresponding to the first signal line) provided in the lock connector 10, and 30a is a signal line (corresponding to the second signal line) provided in the key connector 30. It is connected to the cable 31.

  Reference numeral 14 denotes an inner cylinder of the lock connector 10 into which the key connector 30 is inserted, and 32 denotes a key contact (corresponding to a second contact) provided on the key pile portion of the key connector 30 and connected to the signal line 30a. 13 is an internal contact that is a part of the lock mechanism in which the key contact 32 contacts within the inner cylinder 14, and 15 is a lock mechanism that is disposed in contact with the outer periphery of the inner cylinder 14 and contacts the internal contact 13. A spring-loaded presser 12 that is a part of the inner cylinder 14 is disposed in contact with the outer periphery of the inner cylinder 14, unlocks the lock mechanism, and rotates the key connector 30 and the inner cylinder 14 by a predetermined angle (for example, 180 degrees) This fixed contact is in contact with the internal contact 13 that rotates with this rotation, and this fixed contact 12 is connected to the signal line 11. The fixed contact 12 and the internal contact 13 constitute a first contact.

  The lock mechanism of the lock connector 10 is composed of a cooperating internal contact 13 and a spring-loaded pusher 15, and when the key connector 30 is pulled out from the inner tube 14, the pusher part protrudes into the inner tube 14. When the inner cylinder 14 cannot be rotated (locked state) and the correct key connector 30 is inserted, the spring-loaded pusher 15 is pushed out of the inner cylinder 14 in accordance with the unevenness of the key ridge so that the inner cylinder 14 can be rotated (opened). (Locked state).

Here, the internal contact 13 not only plays a role of connecting the two signal lines 11 and 30a, but also serves as a lock terminal that pushes up the spring-loaded pusher 15 when the lock mechanism is unlocked. .
Since the connector device (the lock connector 10 and the key connector 30) is configured as described above, as the key connector 30 is inserted into the inner cylinder 14 of the lock connector 10, the key contact 32 and the internal contact 13 are inserted. And the key connector 30 and the inner cylinder 14 are rotated 180 degrees, so that the internal contact 13 and the fixed contact 12 come into contact with each other, and the signal line 11 on the lock connector 10 side and the signal line 30a on the key connector 30 side Are connected, and access from the cable 31 to the facility becomes possible.

  Here, the fixed contact 12 that is important for secret protection is housed in the lock connector 10 so that a valid key connector 30 is inserted and the inner cylinder 14 cannot be rotated 180 degrees so that it cannot be connected from the outside. Yes. (In this example, the fixed contact 12 is installed at a position obtained by rotating the inner cylinder 14 by 180 degrees. However, this angle is not necessarily limited to 180 degrees.) Accordingly, equipment that requires security is required. It is possible to protect the unauthorized connection to the terminal, and it is possible to easily perform the connection using the valid key connector 30.

  Examples of facilities that require security include gate checkers for excluding unauthorized entry, firewalls that prevent entry into computer networks, intrusion monitoring devices, and encryption devices. Installation of these devices It is conceivable to use when setting parameters necessary for the time from an external device.

Next, Embodiment 1 of the present invention will be described with reference to FIGS. 3 and 4. FIG. In the above-described reference example, an example in which the key contact 32 of the key connector 30 is provided on the concave and convex portions of the key pile is shown. However, as shown in FIG. May correspond to the second contactor) at a portion where there is no unevenness other than the key mountain.
Further, in the above-described reference example, the internal contact 13 serves as both the transmission path of the signal line 11 and the lock terminal of the mechanical lock mechanism. In the first embodiment, the inner cylinder 14 is shown in FIG. As shown in the external view, the internal contact 13 in Reference Example 1 corresponds to a lock terminal 13a that plays only the role of a mechanical lock mechanism, and an internal contact 20 is provided in the inner cylinder 14 separately from this. deep. The internal contact 20 is disposed so as to contact the key contact 32a when the key connector 30 is inserted into the inner cylinder 14 from the key hole 14a.

For example, when the fixed contact 12 is provided at a position where the internal contact 20 is rotated 180 degrees, the key connector 30 is inserted into the key hole 14a, and the inner cylinder 14 is rotated 180 degrees. The internal contact 20 can be brought into contact.
As described above, even if the internal contact 20 is provided separately from the lock terminal 13a, unauthorized connection can be protected, and proper connection can be easily performed.

  In addition, since the contact with the internal contact 20 may be achieved on the surface of the key connector 30 other than the key pile portion where the key connector 30 and the lock terminal 13a are in contact with each other, the contact tolerance increases. Further, when the contact is provided at a portion of the key connector 30 where there is no unevenness, such as the key contact 32a, a larger number of contacts are provided than when the contact is provided at the key portion. There is an advantage that one single contact can arrange a larger one.
