- 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 to the front side by the spring 8b, whereby 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 (a) is a view of the structure of the defect detection means viewed from one side
- FIG. 4 (b) is a view of this from the other side
- FIG. 4 (c) is an O ⁇ in FIG. 4 (a). It is O line sectional drawing.
- the respective end portions of the sliders 25a and 25b are rotatably connected to connecting portions 49a and 49b in the vicinity of both ends of the link member 41 which is the first link member.
- the sliders 25a and 25b are slidable in the front-rear direction (the left-right direction in the figure and the connector insertion / removal direction). Further, the sliders 25a and 25b are given a force forward (in a direction protruding from the case 9) by a spring member (not shown).
- the link member 43 which is the second link member, is rotatably connected to the substantially central portion of the link member 41 at the connecting portion 51.
- the connecting portion 51 includes, for example, a protrusion formed on the link member 41 and a long hole formed on the link member 43. In this case, by making the size of the hole sufficiently larger than the protrusion, the link member 43 rotates with respect to the link member 41 and the position thereof can be changed.
- the link member 43 is a plate-like member, and a part of the link member 43 is fixed to the case 9 by a pin 53 so as to be rotatable. That is, the link member 43 rotates around the pin 53.
- the cam member 27 is rotatably connected by the connecting portion 55.
- the connecting member 55 rotates with respect to the link member 43, and its position can also be changed.
- the cam member 27 can be slid in the vertical direction (a direction substantially perpendicular to the connector connection direction) by a guide (not shown). Further, a force is applied to the cam member 27 so that the cam member 27 is pulled back downward by a spring or the like not shown.
- a concave groove 57 is provided on the side surface of the cam member 27.
- the distal end of the connecting bar 16 is located behind the cam member 27 at a position shifted laterally.
- a convex portion 59 is provided on the side surface near the tip of the connecting bar 16.
- the convex portion 59 has a form corresponding to the concave groove 57. In the normal state, the groove 57 and the protrusion 59 are shifted in the height direction.
- 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 and FIG. 5B is a side cross-sectional view.
- FIG. 6A and 6B are diagrams showing the operation of the defect detection means.
- FIG. 6A is a diagram of the defect detection means viewed from one side
- FIG. 6B is a diagram of the defect detection means viewed from the other side.
- 6 (c) corresponds to FIG. 4 (c).
- the amount of upward movement of the cam member 27 when the sliders 25a and 25b are completely pushed into the case 9 depends on the groove 57 of the cam member 27 and the connecting bar. This substantially coincides with the amount of deviation of the 16 convex portions 59. Therefore, the positions of the concave groove 57 and the convex portion 59 coincide with each other by the movement of the cam member 27. That is, the interference between the cam member 27 and the connecting bar 16 (gripping member 3) is eliminated. Accordingly, the convex portion 59 can move forward along the concave groove 57. Therefore, the gripping member 3 can slide with respect to the case 9. As described above, the case lock mechanism is released.
- 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. 7 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. 8 to 11 are diagrams showing a process of connecting the power feeding connector 1 to the power receiving connector 33.
- FIG. 8 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. In this state, the tip of the slider 25 does not contact the power receiving connector 33 and protrudes forward of the case 9.
- the gripping member 3 moves forward with respect to the case 9. There is no. That is, when the cam member 27 that is the case lock mechanism is in the normal position, the case 9 is not pushed inward of the gripping member 3 when the gripping member 3 is pushed forward.
- 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 step of the case 9 becomes the peripheral portion of the power receiving connector 33 (in front of the recess 35). Hit the wall). Since the slider 25 protrudes from the step portion of the case 9, the slider 25 comes into contact with the peripheral edge portion of the power receiving connector 33.
- the slider 25 is pushed backward (inside the case 9) (in the direction of arrow A in the figure).
- the link members 41 and 43 and the cam member 27 operate in conjunction with each other as described above. That is, the cam member 27 moves upward and the case lock mechanism is released.
- the case lock mechanism is not released.
- the defect detection means for detecting the presence or absence of a defect in the locking portion is not limited to the method using the slider 25 and the link members 41 and 43 as shown in the figure, and is a mechanism that operates when the case 9 is inserted. Any method is acceptable.
- the operation of the pair of sliders 25 may be moved using a pulley, a piston, or the like. That is, the structure may be any structure as long as the case lock mechanism can be released only when both the pair of sliders 25 are pushed in.
- the holding member 3 of the power feeding connector 1 is further pushed into the power receiving connector 33 side.
- the case 9 is in contact with the power receiving connector 33 and cannot be pushed further.
- the holding state of the gripping member 3 is released from the case 9. That is, the interference between the cam member 27 and the connecting bar 16 is eliminated (FIG. 6C). Accordingly, the connecting bar 16 moves forward.
- 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 lock pin 17a is fitted into the recess 35 as described above. For this reason, the power receiving connector 33 and the power feeding connector 1 are locked in a connected state.
- the defect detection means detects that there is a defect in the vicinity of the recess 35 (locking portion)
- the slider 25 is not pushed into the case 9 and the case lock is not released. Therefore, only when there is no defect in the vicinity of the recess 35, the lock pin 17a fits into the recess 35, and the power supply connector 1 and the power reception connector 33 are locked.
- 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 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.
- 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 gripping member 3 does not move relative to the case 9 in a normal state. Therefore, the gripping member 3 does not move to the case 9 in a state where the case 9 is not completely inserted into the power receiving connector 33.
- FIG. 12 is a conceptual diagram in the case where a defective portion 61 is partially generated in the vicinity of the concave portion 35 (a wall portion on the front surface side of the concave portion 35), and FIG. FIG. 6B is a front view of the power receiving connector 33.
- the pair of sliders 25 a and 25 b are pressed against the power receiving connector 33 when the connectors are connected to each other. Therefore, as shown in the drawing, even if the majority of the recess 35 is missing, if there is a non-deficient part in one part, one slider 25a cannot detect the missing part.
- FIG. 13 is a view showing the operation of the defect detection means in this case
- FIG. 13 (a) is a view seen from one side
- FIG. 13 (b) is a view seen from the other side.
- FIG. 13 is a diagram showing a case where only the slider 25a is brought into contact with the power receiving connector 33 and pushed into the case 9, and the slider 25b corresponds to the position of the chipped portion 61 and is not pushed in without coming into contact with the power receiving connector side. is there.
- FIG. 14 shows a case where only the slider 25b comes into contact with the power receiving connector 33 and is pushed into the case 9, and the slider 25a corresponds to the position of the missing portion 61, so that it is not pushed in without coming into contact with the power receiving connector side.
- FIG. When only the slider 25b is pushed in (in the direction of arrow W in the figure), the link member 41 does not translate backward due to the resistance from the link member 43, but rotates around the connecting portion 51 with the link member 43 ( Arrow Y direction in the figure). Accordingly, in the link member 41, the connecting portion 49b with the slider 25b moves backward around the connecting portion 51, and the slider 25a protrudes forward (in the direction of arrow X in the figure).
- the case lock mechanism is not released unless both the pair of sliders 25a and 25b are pushed in. For this reason, even when a part on the power receiving connector side remains without being lost, it is possible to reliably detect the loss and prevent connection and energization between the connectors.
- the installation position of the slider 25 is not limited to the illustrated example, and any other part may be used as long as it is possible to detect a loss near the engaging portion between the power supply connector 1 and the power reception connector 33.
- the number of sliders 25 is not limited as long as the pair is not necessarily required, and a defect can be reliably detected. For example, more sliders 25 may be provided, and the case lock mechanism may be released only when all the sliders 25 are pushed in.
