Then, the display lamp 60 is driven to cause the red LED 61 to emit light.

  Next, the operation of each part of the power supply side connector 100 when the power supply side connector 100 is attached to the power reception side connector 201 will be described with reference to FIGS. 2 and 3.

Here, as an initial state of the power supply side connector 100, as shown in FIG. 2A, the release operation portion 44 has the pressing portion 44 a at the rear end of the power supply side connector 100 due to the action of the tension coil spring 4 b. Further, the protrusion regulating portion 42 is located at a position where the flange 42 a engages with the flange 32 f of the case main body portion 32 by the action of the compression coil spring 2 a, and the protrusion portion 42 b contacts the front end side straight portion 41 c of the locking portion 41. The front end of the locking portion 41 is in contact with the terminal holding portion 31 in contact therewith. Further, the protrusion push-up portion 43 is urged toward the rear end side of the power supply side connector 100 by the action of the tension coil spring 4a, but the flange 32f of the case main body portion 32 supports the protrusion regulating portion 42, The protrusion 42 b of the protrusion restricting portion 42 supports the locking portion 41, and the locking portion 41 and the terminal holding portion 31 are firmly in contact with each other, whereby a ring is formed between the locking portion 41 and the terminal holding portion 31. There is no gap into which the portion 43a can be inserted, and the ring portion 43a of the protrusion push-up portion 43 cannot be retracted, and is positioned on the distal end side of the power supply side connector 100 with respect to the locking portion 41.

  In this initial state, the charging operator grips the grip portion 32b of the power supply side connector 100, fits the guide 33d of the power supply side connector 100 into the guide groove 201a of the power reception side connector 201, and moves the power supply side connector 100 forward. The terminal holding part 31 and the case coupling part 33 of the power supply side connector 100 are inserted into the shell 201c of the power reception side connector 201.

  Then, as shown in FIG. 2B, the protrusion restricting portion 42 is slid toward the rear end side of the power supply side connector 100 by coming into contact with the frame body 201d constituting the shell 201c of the power receiving side connector 201. Thus, the locking claw 41a of the locking part 41 is exposed. Further, when the protrusion 42b of the protrusion restricting portion 42 slides beyond the range corresponding to the front end side straight portion 41c of the locking portion 41 in the slit 33c of the case connecting portion 33 to the range corresponding to the rear end side straight portion 41d. Since the locking portion 41 has a crank shape, the protrusion 42b does not come into contact with the locking portion 41 (rear end side linear portion 41d).

  At the same time, as shown in FIG. 3A, the protrusion push-up portion 43 is released from the support by the protrusion 42b of the protrusion restricting portion 42 (the flange 32f of the case main body portion 32). The ring portion 43a can be inserted between the terminal holding portion 31 and the locking portion 41, and the protrusion push-up portion 43 slides toward the rear end side of the power feeding connector 100 by the action of the tension coil spring 4a. At this time, since the ring portion 43a is inserted between the terminal holding portion 31 and the locking portion 41 by the taper 43c of the ring portion 43a and the taper 41e of the locking portion 41, the locking claw 41a of the locking portion 41 is Then, it is pushed up to the outer peripheral side of the case connecting portion 33, protrudes from the outer surface of the case connecting portion 33, and engages with the step 201 b of the power receiving side connector 201.

Retreat will be stopped. At this time, the protruding piece 43e of the extending portion 43b is on the rear end side of the power supply connector 100 with respect to the ascending (descending) position of the plunger 51 of the electric lock portion 50, and does not hinder the ascent of the plunger 51 ( The plunger 51 and the protruding piece 43e are in a position where they do not overlap. Further, the extending portion 43 b of the projection push-up portion 43 abuts on the contact switch 71 of the drive circuit 70 to form a closed circuit, thereby driving the electric lock portion 50 and exciting the electromagnetic coil 52 to move the plunger 51. At the same time, the display lamp 60 is driven to cause the red LED 61 to emit light.

  During charging, the plunger 51 of the electric lock unit 50 and the extending portion 43b (projecting piece 43e) of the protrusion pushing portion 43 are engaged, and the release operation unit 44 to the distal end side of the power supply side connector 100 and The movement of the protrusion push-up portion 43 is restricted.

In this detachable state, the charging worker holds the grip portion 32b of the power supply connector 100 and pushes the pressing portion 44a of the release operation portion 44 forward.

As a result, as shown in FIG. 3B, the release operation unit 44 slides to the distal end side of the power feeding side connector 100 together with the projection pushing portion 43, but the front end of the projection pushing portion 43 is the terminal holding portion 31. Since it cannot advance when it contacts the projection 31a, the advancement of the projection push-up portion 43 and the release operation portion 44 is stopped.

  Further, the ring portion 43 a inserted between the terminal holding portion 31 and the locking portion 41 is disengaged from between the terminal holding portion 31 and the locking portion 41 as the projection push-up portion 43 advances. Moreover, since the latching | locking part 41 is urged | biased by 41 d of back end side linear parts by the effect | action of the compression coil spring 2b, the latching | locking part 41 (front end side linear part 41c) and the terminal holding part 31 are comprised. The locking claw 41a of the locking part 41 does not protrude from the outer surface of the case connecting part 33.

  Thereby, the engagement between the locking claw 41a of the locking portion 41 and the step 201b of the power receiving side connector 201 is released, and the charging operator presses the pressing portion 44a of the release operation portion 44 (of the power supply side connector 100). The power feeding connector 100 can be detached from the power receiving connector 201 by pulling the power receiving connector 201 backward while maintaining the state of gripping the grip portion 32b. At this time, the protrusion regulating portion 42 returns to a position where the flange 42a engages with the flange 32f of the case main body portion 32 by the action of the compression coil spring 2a, and the inside of the case main body portion 32 from the slit 33c of the case connecting portion 33. It is possible to prevent foreign matter from entering.

  As described above, when the power supply side connector 100 according to the present embodiment is attached to the power receiving side connector 201, the terminal holding portion 31 and the case connecting portion 33 of the power supply side connector 100 to the shell 201c of the power receiving side connector 201 are connected. At the time of insertion, the locking claw 41 a of the locking part 41 does not protrude from the outer surface of the case connecting part 33. For this reason, the charging operator simply fits the guide 33d of the power supply side connector 100 into the guide groove 201a of the power reception side connector 201 and pushes the power supply side connector 100 forward. Can be smoothly fitted, and there is an effect that the workability of the charging work can be improved.
