- One end of the link member 10a is connected to the rear side of the pin 23c of the lock lever 7 so as to be rotatable by the pin 23d.
- the pin 23 d is a rod-like member, and is formed with substantially the same diameter as a whole without expanding the diameter of the end portions on both sides. Therefore, the pin 23d passing through the lock lever 7 and the link member 10a is not formed with a retaining mechanism. Therefore, a retaining plate 25 that prevents the pin 23 d from coming off is fixed on both sides of the lock lever 7 with the screws 27.
- the recessed parts 29 and 31 are formed in the circumference
- FIG. The length of the pin 23d is slightly shorter than the interval between the retaining plates 25 (the width of the lock lever 7 in the figure). Also, considering the thickness of the link member 10a, the length of the pin 23d and the recess 29 so that when the retaining plate 25 is removed, the predetermined length of the end of the pin 23d is exposed in any direction. , 31 is set.
- the other end of the link member 10a is connected to one end of the link member 10b so as to be rotatable by a connecting portion 15c. Further, the other end of the link member 10b is rotatably connected to the grip member 3 by a pin 23e. In a normal state, the link members 10a and 10b are arranged at an angle so as to be bent forward at the connecting portion 15c.
- the electromagnetic solenoid 22 is fixed to the gripping member 3 in the vicinity of the connecting portion 15c.
- the plunger 22a penetrates the electromagnetic solenoid 22 and the plunger 22a can be operated by operating the electromagnetic solenoid 22.
- the end of the plunger 22a is connected to the connecting portion 15c.
- the plunger 22a is connected from the bent part side (front) of the link members 10a and 10b toward the rear in a normal state.
- the electromagnetic solenoid 22 is provided with a spring 8b.
- the spring 8b applies a force to the plunger 22a in the direction in which the plunger 22a is pulled back. Therefore, normally, the plunger 22a is pulled back forward (left side in the figure) by the spring 8b, and thereby the connecting portion 15c is also pulled forward.
- the link members 10a and 10b receive a force in a direction in which the angle of the link members 10a and 10b decreases as the connecting portion 15c is pulled forward. At this time, since the pin 23e is fixed to the gripping member 3, the pin 23d is pulled downward.
- FIG. 4 is a side view showing a state in which the cover 3a is opened. By opening the cover 3a, the vicinity of the connecting portion between the lock lever 7 and the link member 10a is exposed to the outside. Specifically, the retaining plate 25 can be exposed.
- FIGS. 5A and 5B are views showing the power supply connector 1 in a state where the gripping member 3 is moved.
- FIG. 5A is a side view
- FIG. 5B is a side cross-sectional view.
- the connecting portion 15a joined to the gripping member 3 is moved forward.
- the arm 13 rotates about the pin 23a as a rotation axis (in the direction of arrow D in the figure).
- the connector main body 11 connected to the arm 13 by the connecting portion 15b moves in the same direction as the gripping member 3 (in the direction of arrow E in the figure).
- connection position with respect to the arm 13 differs between the gripping member 3 and the connector main body 11, the moving distance of the gripping member 3 with respect to the case 9 and the moving distance of the connector main body 11 are different. Specifically, if the ratio of the distances of the connecting portions 15a and 15b from the pin 23a is 2: 1, if the moving distance of the gripping member 3 relative to the case 9 is 2, the connector body 11 moves by a distance of 1. To do. That is, the mechanism such as the arm 13 functions as a speed reduction mechanism. By providing the speed reduction mechanism, the connector can be inserted and removed with a small force.
- the gripping member 3 moves forward with respect to the case 9 so that the fitting portion 17b and the fitting portion 21 are engaged with each other.
- the lock member 17 rotates about the pin 23b as a rotation axis. That is, when the fitting portion 17b side is pushed down, the lock member 17 rotates, and the lock pin 17a at the other end is pushed up. For this reason, the lock pin 17a protrudes outward from the case 9 through the hole (in the direction of arrow G in the figure).
- the lock member 17 may be formed with a spring or the like so as to always return to the state shown in FIG. 5 (the state in which the fitting portion 17b is pushed down).
- detection means for detecting the position of the lock pin 7a may be provided in the vicinity of the concave portion 19 of the case 9. By doing in this way, it can be detected that the lock pin 7a is securely fitted in the recess 19.
- FIG. 6 is an enlarged view of the vicinity of the lock lever 7.
- the link member 10a is connected to the lock lever 7 by the pin 23d. Therefore, when the lock lever 7 moves upward, the link member 10a is pulled upward (in the direction of arrow J in the figure).
- the plunger 22a connected to the connecting portion 15c moves to the rear side (direction protruding from the main body of the electromagnetic solenoid 22) against the pullback force of the spring 8b (in the direction of arrow K in the figure). Therefore, when the plunger 22a cannot move relative to the main body of the electromagnetic solenoid 22 due to freezing or the like, the connecting portion 15c cannot move. Therefore, in such a case, the lock lever 7 cannot be rotated around the pin 23c, and the lock pin 7a cannot be brought into the state shown in FIG. For this reason, an operator can grasp
- the lock lever 7 functions as a lock unit that locks the grip member 3 (and the connector main body 11) from moving with respect to the case 9. Further, it operates as a release mechanism for releasing the lock by operating the lock lever 7 (pressing down an external end of the lock lever 7). Therefore, the connection state of the connector can be securely held and can be easily released.
- a parallel link may be used for the sliding portion between the gripping member 3 (or the connector main body 11) and the case 9.
- the parallel link By using the parallel link, rattling does not easily occur when the gripping member 3 (or the connector main body 11) and the case 9 slide, and the movement range can be restricted.
- FIG. 7 to 10 are diagrams showing a process of connecting the power feeding connector 1 to the power receiving connector 33.
- FIG. 7 the power supply connector 1 in the normal state is opposed to the power reception connector 33 to be connected. Specifically, the tip of the case 9 is inserted into the power receiving connector side. A connector body 37 is accommodated in the power receiving connector 33. In this state, the male and female terminals of the connector bodies 11 and 37 are arranged with a slight gap so that they are not yet connected.
- a concave portion 35 as a locking portion is formed on the inner surface on the power receiving connector 33 side at a position corresponding to the lock pin 17a.
- a guide or the like for positioning the power receiving connector 33 may be formed on the outer surface of the case 9.
- the gripping member 3 can be moved forward with respect to the case 9.
- the connector main body 11 moves forward with respect to the case 9 as the gripping member 3 moves (in the direction of arrow E in the figure). Therefore, the connector body 11 protrudes from the front of the case 9 and is connected to the connector body 37 on the power receiving connector side.
- the gripping member has a moving distance twice as large as the connection allowance for connecting the connector main body 11 and the connector main body 37.
- the connector body 11 can be moved by a distance that allows the connectors to be connected. That is, the connectors can be connected by pressing the gripping member 3 with half the force required for connecting the connectors (ie, connection resistance).
- the speed reduction ratio of the speed reduction mechanism is appropriately set in consideration of connection resistance and workability.
- the connected connector can be energized.
- the electromagnetic solenoid 22 When energization of the connector is started, the electromagnetic solenoid 22 operates as shown in FIG.
- the electromagnetic solenoid 22 always presses the plunger 22a against the spring 8b in the direction of the connecting portion 15c during energization (in the direction of arrow L in the figure).
- the plunger 22a By the operation of the plunger 22a, the link members 10a and 10b are moved in the opening direction. Therefore, the upper end portion (pin 23d) of the link member 10a is pushed upward (in the direction of arrow M in the figure). Therefore, it becomes impossible to release the lock lever 7 during energization. For this reason, the worker cannot release the lock of the lock lever 7 during energization, and the connection of the connector is not pulled out during energization.
- the operation of the electromagnetic solenoid 22 is stopped by stopping energization.
- the plunger 22a is pulled back forward by the spring 8b.
- the lock pin 7a can be pushed up by pushing down the end of the lock lever 7.
- the gripping member 3 is pulled back, so that the fitting portion 17b moves onto the fitting portion 21, thereby releasing the lock by the lock pin 17a. For this reason, the power feeding connector 1 can be easily detached.
- an abnormality may occur in the electromagnetic solenoid 22 during energization.
- the electromagnetic solenoid 22 may not operate due to freezing or failure.
- the lock lever 7 does not operate in the first place.
- the electromagnetic solenoid 22 becomes abnormal after energization is started once, the lock lever 7 does not operate in the locked state, so that the lock cannot be released. Therefore, even if energization is terminated, the power feeding connector 1 cannot be removed from the power receiving connector 33. In this case, it is necessary to release the lock mechanically.
- FIG. 11A is a plan view showing a state in which the power feeding connector 1 is connected to the power receiving connector 33 of the vehicle body 34.
- the power receiving connector 33 formed on the vehicle body 34 is usually protected by a lid 38. By opening the lid 38, the power receiving connector 33 can be exposed and the power feeding connector 1 can be connected.
- a lid 38 opened on the left side of the power supply connector 1 in the figure is disposed in a state where the power supply connector 1 is connected.
- FIG. 11B corresponds to FIG.
- the lid 38 may be located on the right side of the power supply connector 1 in the figure.
- the retaining plate 25 may be removed from the left side to expose the vicinity of the end of the pin 23d.
- the lock lever 7 and the link member 10a can be disconnected by removing the pin 23d.
- the pin 23d can be extracted easily.
- FIG. 13 is a diagram illustrating a state in which the cover 3a is removed.
- the bolt 4 that is a fixing member is fastened to the gripping member 3 from behind the power supply connector 1. Therefore, the bolt 4 can be extracted from the rear of the power supply connector 1 (gripping member 3). Therefore, the bolt 4 and the tool do not interfere with the vehicle side cover 39.
- the rear of the power supply connector 1 (the gripping member 3) is substantially opposite to the connection direction of the power supply connector 1 (left side in the figure), and there is an obstacle in the upper part (or the lower part or both sides) of the power supply connector 1. This is the direction (right direction in the figure) in which the operation of extracting the bolts and the like can be performed even when an object is close.
- the cover 3a is removed.
- the cover 3a can also be removed from behind the power supply connector 1 (gripping member 3). Therefore, the cover 3a does not interfere with the vehicle side cover 39.
- the fixing member for fixing the cover 3a may not be the bolt 4, and other fixing members may be used as long as it is possible to release the fixing of the cover 3a from the rear side of the power supply connector 1 (gripping member 3). It can also be applied.
- the power supply connector 1 of the present embodiment it is possible to easily connect to the power receiving connector 33 without requiring a large force.
- the pushing operation of the gripping member 3 performed by the operator coincides with the connection direction of the connector main body 11, the worker can easily grasp the connection work intuitively.
- the cover 3a is provided on a part of the gripping member 3, and the connecting portion between the lock lever 7 and the link member 10a can be exposed by opening the cover 3a. Therefore, even when there is an abnormality in the electromagnetic solenoid 22, the pin 23d can be easily removed and the lock by the lock lever 7 can be released urgently.
- the pin 23d since the pin 23d has a rod shape that does not have a head portion, a flange portion, or the like at the end portion, it can be extracted from either side. Therefore, the pin 23d can be easily extracted regardless of the arrangement of the lid 38 of the vehicle. Further, by arranging the retaining plate 25 on both sides of the pin 23d, the pin 23d does not fall off during use.
- the retaining plate 25 is fixed to the lock lever 7 with the screw 27, but the present invention is not limited to this.
- Other structures may be used instead of the retaining plate 25 as long as the pin 23d can be pulled out from both sides and can be prevented from falling off during use.
- FIG. 14 (a) is a cross-sectional view seen from the front side in the vicinity of the connecting portion between the lock lever 7 and the link member 10a.
- a retaining plate 25a may be formed in a rib shape on the inner surface (lower surface) of the cover 3a.
- the cover 3a and the retaining plate 25a can be integrally formed.
- FIG. 14B when the cover 3a is removed, the retaining plate 25a is also removed at the same time, so that the work of removing the retaining plate 25a becomes unnecessary. Even in this case, the pin 23d can be extracted on either side.
- the example in which the pin 23d of the connecting portion between the lock lever 7 and the link member 10a is extracted to release the lock by the lock lever 7 has been described.
- the lock lever 7 itself is unlocked. If possible, the pin that can be removed in the event of an abnormality may be another pin.
