Description

  The present invention relates to an AC / DC combined type connector and an arc breaking mechanism.

  In recent years, power generation methods using renewable natural energy such as solar power generation and wind power generation as renewable energy are becoming common. Such a power generation method is a direct current power source, and generally uses the generated electricity for charging a battery, or sells power to a power company in a power generation business through a transmission line.

  On the other hand, a technology for charging electricity generated by using renewable natural energy to a battery such as an automobile has been developed. In this way, if electricity generated using renewable natural energy can be charged to a battery and used safely in the home, it will not only contribute to solving energy problems, but it will also be an off-the- Electrification can be promoted on a grid (rural).

  However, the amount of power generated using renewable natural energy is generally a high voltage direct current of 600 V to 1200 V, and an arc generated between the outlet connector (socket outlet) and the plug connector when the direct current conduction path is interrupted. Must be properly extinguished. Here, in the following description, the outlet connector and the plug connector may be collectively referred to as a connector.

  Various DC power supply connectors having a configuration for extinguishing an arc generated with the other connector when the DC connection is interrupted have been developed (see, for example, Patent Document 1). However, all of these are limited areas such as data centers, and are not applied to household appliances.

Japanese Patent Laying-Open No. 2015-187998

  The general power connector widely used in electrified areas is of the AC type. As described above, even when trying to promote off-the-grid using renewable natural energy in areas not electrified, for example, If the connector for power supply is replaced with the connector for DC power supply as in Patent Document 1 described above and the power supply circuit is not changed, the household electrical appliance cannot be used in an uncharged area.

Many areas that are not electrified are in poor environments, and it is rare to purchase new home appliances. Areas called advanced countries dispose of and recycle many home appliances. If these discarded home appliances can be reused as DC home appliances and used within the grid, the living environment in non-electrified areas can be improved. It becomes possible. Many home appliances have a circuit that converts AC to DC in the power supply circuit, and many home appliances operate on DC, so the home appliance can be used on DC by simply replacing the power supply circuit that steps down to the specified DC voltage. It becomes like this. For this reason, off-the-grid using renewable natural energy has great potential for the global environment and mankind.
However, electricity generated by renewable natural energy is a direct current high voltage, and measures such as electric shock are important for use in a living environment as described above.

  For this reason, an AC / DC combined connector that can safely and satisfactorily extinguish arcs that occur with the other connector when the DC power supply is shut off and that can also be connected to an AC power source is connected to the home appliance power supply. If it can be used for the appliance, the appliance can be used in both the electrified area and the area not yet electrified by off-the-grid without exchanging the connector.

  For example, if a renewable natural energy power generation device and a battery are connected to a container house having an AC outlet connector and DC power can be transmitted through an AC path, an environment in which both DC and AC can be used can be constructed simply by replacing the outlet connector. This is an effective means especially in the region of 220V to 240V, and the effective value of alternating current is close to the direct current voltage generated by renewable natural energy.

  The second slider 10 is pushed down by the insertion operation of the electrode terminal 2 a of the other connector 2, and the pushing portion 10 b of the second slider 10 is inserted into the second insertion portion 7 c of the first slider 7. Thus, the tongue 7g of the tongue spring 7e of the first slider 7 is brought into contact with the AC / DC combined type connector 1 from the front. At this time, immediately before the insertion of the load side terminal 5 of the AC / DC combined type connector 1 in the electrode terminal 2a of the other connector 2 into the insertion portion 5a is completed, the pushing portion 10b of the second slider 10 is The tongue 7g of the tongue-shaped spring 7e of the first slider 7 comes into contact.

  Accordingly, the first slider 7 is pushed out along the guide portion 11a of the lower cover 11 to the rear side (first direction) of the AC / DC combined type connector 1 by the pushing portion 10b of the second slider 10. That is, the insertion operation of the electrode terminal 2 a of the other connector 2 is converted into a backward movement operation of the AC / DC combined type connector 1 in the first slider 7.

  As shown in FIGS. 9 and 10, the contact 8 moves between the rear end of the upper horizontal portion 4 c of the power supply side terminal 4 and the protruding portion 5 e of the load side terminal 5 as the first slider 7 moves. Is inserted into the power supply side terminal 4 and the load side terminal 5 via the contact 8.

  At this time, when the insertion of the load side terminal 5 of the AC / DC combined type connector 1 in the electrode terminal 2a of the other connector 2 into the insertion portion 5a is completed, the power source side terminal 4 and the load side terminal 5 are electrically connected. The contact 8 moves so as to be connected to. That is, the power supply side terminal 4 and the load side terminal 5 are electrically connected until the insertion of the load side terminal 5 of the AC / DC combined type connector 1 into the insertion portion 5a of the electrode terminal 2a of the other connector 2 is completed. Not connected to. Further, as the first slider 7 moves, the return mechanism 9 is pushed toward the rear of the AC / DC combined type connector 1 and elastically deforms.

  Here, for example, the rear side of the first slider 7 contacts the rear side wall surface of the guide portion 11 a in the lower cover 11, and the tongue spring 7 e of the first slider 7 is pushed out by the pushing portion 10 b of the second slider 10. The first slider 7 may be sandwiched and fixed from the front-rear direction of the AC / DC combined type connector 1 in contact with the AC. As a result, the pushing portion 10b of the second slider 10 and the guide portion 11a of the lower cover 11 move the first slider 7 to the rear of the AC / DC combined type connector 1, that is, the contact 8 The power-side terminal 4 and the load-side terminal 5 can be electrically connected via each other, and can function as a fixing mechanism that fixes the first slider 7 in a state where the return mechanism 9 is deformed.

  Next, the operation of the arc breaking mechanism 3 when the electrode terminal 2a of the other connector 2 is removed from the AC / DC combined connector 1 of the present embodiment will be described. As described above, as the electrode terminal 2a is removed from the state in which the electrode terminal 2a of the other connector 2 is inserted into the insertion portion 5a of the load side terminal 5 in the AC / DC combined type connector 1.

The first slider 7 is pushed back to the front (second direction) of the AC / DC combined type connector 1 by the restoring force of the mechanism 9.

  As the first slider 7 moves, the contact 8 moves to the front of the AC / DC combined type connector 1 so that the electrical connection between the power supply side terminal 4 and the load side terminal 5 via the contact 8 is established. Blocked. At this time, the electrical connection between the power supply side terminal 4 and the load side terminal 5 is interrupted before the electrode terminal 2a of the other connector 2 is completely removed from the insertion portion 5a of the load side terminal 5. The contact 8 moves.

  Here, for example, the first notch portion 7 a of the first slider 7 contacts the fitting portion 6 b of the base 6 while the first insertion portion 7 b of the first slider 7 is pushed by the return mechanism 9. The first slider 7 is preferably sandwiched and fixed from the front-rear direction of the AC / DC combined type connector 1. Accordingly, the return mechanism 9 and the fitting portion 6b of the base 6 can function as a fixing mechanism that fixes the first slider 7 with the AC / DC combined type connector 1 moved forward.

  Thus, the AC / DC combined type connector 1 of the present embodiment is connected to the power source side terminal 4 before the electrode terminal 2a of the other connector 2 is completely removed from the insertion portion 5a of the load side terminal 5. The electrical connection with the load side terminal 5 is cut off. Therefore, an arc generated between the load side terminal 5 of the AC / DC combined use connector 1 and the electrode terminal 2a of the other connector 2 can be suppressed. Therefore, the safety at the time of use can be improved.

  Even if an arc is generated between the load-side terminal 5 of the AC / DC combined type connector 1 and the electrode terminal 2a of the other connector 2, the electrical connection between the power-side terminal 4 and the load-side terminal 5 Since the connection is interrupted, the arc can be extinguished. Here, in this embodiment, since the electrical connection between the power supply side terminal 4 and the load side terminal 5 can be quickly cut off by the return mechanism 9, even if an arc occurs, the generation time of the arc short. Therefore, the lifetime and reliability of the AC / DC combined type connector 1 can be improved.

  Even if an arc is generated between the power supply side terminal 4 and the load side terminal 5, the generation of the arc is in the lower cover 11, so that it is safe.

  Furthermore, since the AC / DC combined use connector 1 is originally an AC outlet connector, it can also be used for AC connection. At this time, when the electrode terminal of the plug outlet is not inserted, the electrical connection between the power supply side terminal 4 and the load side terminal 5 is cut off, so that even if the load side terminal 5 is touched by mistake, There is no electric shock. Therefore, it can contribute to the improvement of safety.

  Here, the arc breaking mechanism 3 preferably includes a magnet 14 in the vicinity of a position where the power supply side terminal 4 and the load side terminal 5 are electrically connected via the contact 8. For example, as shown in FIGS. 11 and 12, the magnet 14 is configured such that the rear end portion of the upper horizontal portion 4 c of the power supply side terminal 4 and the protruding portion 5 e of the load side terminal 5 are electrically connected via the contact 8.
