Description

[Technical Field]

[0001] The present invention relates to a connector locking device and an inlet. [Background technology]

[0002] For example, electric vehicles and plug-in hybrid vehicles charge their batteries by mating a charging connector connected via a cable to a power supply device installed in a home, a charging station, or the like with an inlet installed in the vehicle to supply commercial power to the battery. Therefore, a connector locking device has been proposed in which a lock pin that is driven forward and backward by an actuator is provided in the charging connector, and the lock pin engages with a locking portion of the inlet (Patent Document 1). According to this connector locking device, a cover covers the opening of the housing of the charging connector, preventing the actuator housed in the housing from falling out of the housing opening.

[0003] Furthermore, with the connector locking device described above, it is conceivable that a malfunction of the actuator may prevent the lock pin from being moved to the retracted position, making it impossible to separate the mated charging connector and inlet. Patent Document 1 describes that the engagement between the cover and the housing is easily released when the charging connector is forcibly pulled out of the inlet. When released, the actuator falls out of the opening in the housing, allowing the charging connector to be removed from the inlet with the actuator and cover remaining inside the inlet.

[0004] However, the above-described conventional connector locking device has a problem in that the actuator is left in the inlet, and the actuator cannot be easily removed from the inlet using the lock pin. [Prior art documents] [Patent documents]

[0012] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0013] For the sake of convenience, the following definitions are used for "front," "rear," "left," "right," "upper," and "lower" as shown in Figures 1 to 11. The "front-rear direction," "left-right direction," and "up-down direction" are perpendicular to one another. The "lower direction" corresponds to the "retraction direction" of the present invention, the "rear direction" corresponds to the "removal direction" of the present invention, and the "front direction" corresponds to the "fitting direction" of the present invention.

[0014] The connector lock device according to this embodiment includes a charging connector 1 (see FIG. 1) that supplies power to a battery, and an inlet 2 (see FIG. 1) into which the charging connector 1 fits. The charging connector 1 is attached to the end of a cable of a power supply device installed in a home, a charging station, or the like. The inlet 2 is installed in a vehicle, and by fitting the charging connector 1, commercial power is supplied to the battery installed in the vehicle to charge it.

[0015] As shown in Figures 1, 3 and 4, the charging connector 1 includes a mating connection terminal 3 that fits into the connection terminal 10 of the inlet 2, a plug housing 4 as a housing having a pair of terminal accommodating chambers 41, 41 that accommodate the mating connection terminal 3, a solenoid 5 as an actuator housed in the plug housing 4, a lock pin 6 that is driven back and forth by the solenoid 5 to lock the removal of the charging connector 1 from the inlet 2, and a cover member 7 that covers the front side of the solenoid 5 and is engaged with the plug housing 4.

[0016] The plug housing 4 is molded from an electrically insulating synthetic resin. As shown in Figures 1 and 3, the plug housing 4 includes a cylindrical plug housing body 42, the pair of terminal accommodating chambers 41, 41, a retaining wall 43 (see Figure 4) that holds the solenoid 5 in a predetermined position within the plug housing body 42, and a notch 44 that allows the lock pin 6 to protrude outside the plug housing 4.

[0017] The plug housing body 42 is tubular and elongated in the left-right direction, and is open in the front-rear direction. The plug housing body 42 has a top wall 42a and a bottom wall 42b that face each other in the vertical direction, and a left wall 42c and a right wall 42d that face each other in the horizontal direction and are provided between the top wall 42a and the bottom wall 42b. A pair of terminal accommodating chambers 41, 41 are provided in the plug housing body 42, and are connected to the left wall 42c and the right wall 42d, respectively.

[0018] As shown in Fig. 4, the retaining wall 43 extends from the top wall 42a to the bottom wall 42b inside the plug housing body 42 and contacts and supports the rear side of the solenoid 5. The retaining wall 43 is provided in the center of the front side of the plug housing body 42 in the left-right direction. The retaining wall 43 has a lead wire passing hole 42e through which the lead wire 9 drawn from the solenoid 5 passes. The lead wire 9 passes through the lead wire passing hole 42e and is drawn out from the rear opening of the plug housing body 42.

[0019] 1 and 3, the notch 44 is provided in the left-right center of the top wall 42a of the plug housing body 42. The notch 44 is provided along the front-rear direction and extends from a position that faces the lock pin 6 in the up-down direction when the solenoid 5 is held in a predetermined position to the front end.

[0020] As shown in Fig. 3, the solenoid 5 includes a case 8 made of a magnetic material, a plunger (not shown) that moves up and down when an excitation coil (not shown) built into the case 8 is excited, and a lead wire 9 one end of which is connected to the excitation coil. The plunger is always biased downward toward a retracted position by a spring elastic force. The other end of the lead wire 9 is connected to an electronic control unit (not shown), and when the solenoid 5 is energized and excited by a drive signal from the electronic control unit, the plunger moves upward toward an advanced position against the retraction biasing force.

[0021] The lock pin 6, which is driven to move forward and backward by the solenoid 5, has its lower end fixed to a disk-shaped plunger and moves integrally with the plunger. In the retracted position, the tip (upper end) of the lock pin 6 retracts into the plug housing 4, and in the advanced position, the tip protrudes outside the plug housing 4 through the notch 44. Note that, for example, by configuring the plunger of the solenoid 5 so that the lock pin 6 is integrally formed, the plunger itself can serve as a locking member for the charging connector 1.

[0022] The cover member 7 is molded from an electrically insulating synthetic resin. As shown in Figure 4, the cover member 7 covers the front side of the solenoid 5 and is engaged with the plug housing 4. By positioning the solenoid 5 between the cover member 7 and the retaining wall 43, the solenoid 5 can be held in a predetermined position. The cover member 7 also prevents the solenoid 5 from falling out of the front opening of the plug housing body 42.

[0023] As shown in FIG. 5, the cover member 7 includes a substantially rectangular, flat cover body 71 and four locking portions 72 projecting from the four corners of the inner surface of the cover body 71 toward the rear of the plug housing 4. Each locking portion 72 is configured with a cantilevered locking arm 72b having a locking protrusion 72a at its tip that engages with an engaging hole 42g (see FIGS. 1 and 3) that penetrates the top wall 42a and the bottom wall 42b of the plug housing 4. The locking arm 72b projects rearward from the cover body 71. The locking protrusion 72a that engages with the engaging hole 42g in the top wall 42a projects upward from the tip of the locking arm 72b. The locking protrusion 72a that engages with the engaging hole 42g in the bottom wall 42b projects downward from the tip of the locking arm 72b. A cushioning material 73 is disposed on the inner surface of the cover body 71 to elastically hold the solenoid 5 housed between the cover body 71 and the holding wall 43, thereby suppressing rattle.

[0024] As shown in FIG. 2 , the inlet 2 includes a connection terminal 10 that fits into the mating connection terminal 3 of the charging connector 1, a housing 11 that has a pair of terminal accommodating cylindrical portions 111, 111 that accommodate the connection terminal 10, and an engaging portion 12 that engages the lock pin 6 of the charging connector 1 to lock the charging connector 1 from being removed from the inlet 2.

[0025] The connection terminal 10 is a female terminal made of a conductive metal material, and is composed of a plurality of flexible pieces arranged in a cylindrical shape.

[0026] 2, the housing 11 of the inlet 2 is made of an electrically insulating synthetic resin. The housing 11 has a cylindrical housing main body 112 and the pair of terminal-receiving cylindrical portions 111, 111.

[0027] The housing body 112 is formed in a cylindrical shape that is long in the left-right direction and is open toward the rear. The plug housing body 42 of the charging connector 1 is inserted into the housing body 112 through this rear opening. The housing body 112 has a top wall 112a and a bottom wall 112b that face each other in the vertical direction, and a left wall 112c and a right wall 112d that are provided between the top wall 112a and the bottom wall 112b and face each other in the left-right direction.

[0028] The pair of terminal accommodating cylindrical portions 111, 111 are provided at a distance from each other in the left-right direction within the housing main body 112. A rear opening is formed at the rear end of the terminal accommodating cylindrical portion 111, into which the mating connection terminal 3 of the charging connector 1 is inserted. A high-voltage cable (not shown) connected to the rear end of the connection terminal 10 is drawn out from the front opening of the terminal accommodating cylindrical portion 111.

[0029] 2 and 6, the locked portion 12 protrudes downward from the top wall 112a of the housing main body 112, and is formed with a locking hole 12a into which the lock pin 6 is inserted. The locking hole 12a is formed by vertically penetrating the locked portion 12 and the top wall 112a. In this embodiment, as shown in FIG. 2, the left side of the locking hole 12a of the locked portion 12 is cut out.

[0030] 7, the locked portion 12 has a locking surface 12b and an inclined surface 12c. The locking surface 12b is provided on the rear side of the inner surface of the locking hole 12a and is engaged with (comes into contact with) the tip of the lock pin 6. The locking surface 12b is provided perpendicular to the front-rear direction. The inclined surface 12c is provided below the locking surface 12b and is provided so as to approach the solenoid 5 as it moves rearward. The inclined surface 12c is provided with a greater height in the up-down direction and a greater length in the front-rear direction than a chamfered inclined surface 12f that is provided by cutting out a corner between the outer surface 12d and the lower surface 12e on the rear side of the locked portion 12.

[0031] Next, we will explain the operation of the connector locking device when mating the inlet 2 and charging connector 1 according to the above-described embodiment. When mating the charging connector 1 with the inlet 2, the plunger of the de-energized solenoid 5 in the charging connector 1 is always biased backward by the elastic force of the spring toward a downward retracted position. Therefore, the tip of the lock pin 6, the rear end of which is fixed to the plunger, is retracted within the plug housing 4 and is not exposed to the outside of the plug housing 4. Therefore, the charging connector 1 can be inserted and mated into the inlet 2.

[0032] When the charging connector 1 is inserted deeply into the inlet 2 from the rear opening thereof, the mating connection terminal 3 of the charging connector 1 is fitted into the connection terminal 10 of the inlet 2 and connected.

[0033] Furthermore, when the charging connector 1 and the inlet 2 are fully mated, the tip of the lock pin 6 provided on the plug housing 4 is positioned in a position facing the locking hole 12a in the locking portion 12 provided on the housing 11 in the vertical direction. When the solenoid 5 is energized and excited by a drive signal from an electronic control unit (not shown), the plunger moves to an upward advanced position against the backward biasing force.

[0034] 6, the tip of the lock pin 6, which is driven forward and backward by the solenoid 5, protrudes out of the plug housing 4 and is inserted into and locked in the locking hole 12a of the locked portion 12. Thus, the charging connector 1 and the inlet 2 are maintained in a mated state and are prevented from separating from each other.

[0035] In the charging connector 1 according to the present embodiment described above, the tip of the lock pin 6, which locks the charging connector 1 against removal from the inlet 2, is in a retracted position retracted within the plug housing 4 when charging is not in progress (when the solenoid 5 is not energized). This prevents the lock pin 6 from being damaged by a direct impact, such as when the charging connector 1 is dropped.

[0036] Furthermore, the lock pin 6, which is locked to the locked portion 12 of the inlet 2 to lock the charging connector 1 from being removed from the inlet 2, is driven to move forward and backward by the solenoid 5. This allows the height dimension of the plug housing 4 to be reduced.

[0037] Furthermore, when the charging connector 1 is inserted and fitted into the inlet 2, the top wall 42a of the plug housing 4 comes into sliding contact with the top wall 112a of the housing 11, but the tip of the lock pin 6, which is positioned in a retracted position housed within the plug housing 4, does not come into sliding contact with the housing 11 of the inlet 2, etc., and there is no risk of wear.

[0038] Therefore, with the charging connector 1 and inlet 2 according to this embodiment, the charging connector 1 does not become easily detached from the inlet 2 due to damage such as breakage or wear of the lock pin 6. As a result, a compact connector locking device can be provided that can reliably prevent the charging connector 1 from being detached from the inlet 2.

[0039] Next, we will explain the operation of the connector locking device when the charging connector 1 according to the present embodiment described above is forcibly removed from the inlet 2. For example, a malfunction of the solenoid 5 may prevent the lock pin 6 from retracting to the retracted position, making it impossible to separate the mated charging connector 1 and inlet 2. In such a case, the charging connector 1 must be forcibly pulled out of the inlet 2 to remove it from the inlet 2. At this time, excessive load is applied not only to the locked portion 12 and lock pin 6 of the housing 11 but also to the solenoid 5 itself and the plug housing 4, which may cause fatal damage to the charging connector 1 and inlet 2.

[0040] In the charging connector 1 of this embodiment, the cover member 7 is provided with a locking portion 72 that locks the cover member 7 to the plug housing 4 with a predetermined locking force that will not damage the lock pin 6 and the locked portion 12 in the advanced position when the charging connector 1 moves in the removal direction (rearward).

[0041] In other words, when a rearward force greater than the predetermined locking force acts on the solenoid 5 housed in the plug housing 4, the locking portion 72 is released from its locking position before the lock pin 6 or the locked portion 12 in the advanced position is damaged.

[0042] Here, the specified locking force of the locking portion 72 is a locking force of such magnitude that the locking protrusion 72a engaged with the engagement hole 42g will not be disengaged by the rearward force acting on the solenoid 5 during normal use, but when a large rearward force that is large enough to damage the lock pin 6 or the locked portion 12 acts on the solenoid 5, the locking protrusion 72a engaged with the engagement hole 42g will be disengaged.

[0043] Therefore, if the charging connector 1, in which the lock pin 6 cannot be retracted to the retracted position, is forcibly pulled out from the inlet 2, the locking portion 72 is released from the lock and the cover member 7 is removed from the plug housing 4 before the lock pin 6 in the advanced position or the locked portion 12 is damaged. As a result, the charging connector 1 can move in the removal direction from the inlet 2, with the cover member 7 and solenoid 5 remaining inside the inlet 2, as shown in FIG.

[0044] As shown in Figure 7, before the plug housing 4 is removed from the inlet 2, the tip of the lock pin 6 protrudes above the inclined surface 12c of the locked portion 12 and engages with the locking surface 12b. After the plug housing 4 is removed from the inlet 2, as shown in Figure 8, the solenoid 5 moves downward by the thickness of the bottom wall 42b of the plug housing main body 42. At this time, as shown in Figure 9, the tip of the lock pin 6 is positioned below the locking surface 12b and faces the inclined surface 12c in the front-rear direction. In other words, the provision of the inclined surface 12c enables the lock pin 6 to move rearward from the position where it is engaged with the locked portion 12.

[0045] When the solenoid 5 is moved rearward, the tip of the lock pin 6 slides against the inclined surface 12c and is retracted, as shown in Figures 10(a) and 10(b), and the solenoid 5 can also be removed from the inlet 2, as shown in Figure 11.

[0046] According to the embodiment described above, when the plug housing 4 is removed from the inlet 2 leaving the solenoid 5 behind, the solenoid 5 moves downward and is provided so as to be movable in the removal direction (rearward) from the position where it is locked with the locked portion 12. This allows the solenoid 5 to be easily removed from the inlet 2 in an emergency.

[0047] According to the embodiment described above, the notch 44 is provided so as to extend to the front end of the plug housing 4. Furthermore, the cover member 7 covers the front side of the solenoid 5 and is engaged with the plug housing 4. As a result, in the event of a malfunction in which the lock pin 6 cannot be retracted to the retracted position, pulling the charging connector 1 rearward releases the engagement between the plug housing 4 and the cover member 7. Furthermore, the lock pin 6 moves out of the notch 44 from the front end opening of the plug housing 4. As a result, the plug housing 4 can be removed from the inlet 2, leaving the solenoid 5 and the cover member 7 behind.

[0048] According to the embodiment described above, the inclined surface 12c, which approaches the solenoid 5 as it extends rearward in the locked portion 12, is provided below the locking surface 12b. As a result, when the solenoid 5 is pulled out rearward, the tip of the lock pin 6 slides against the inclined surface 12c, allowing the tip of the lock pin 6 to be retracted. This allows the solenoid 5 to be easily removed from the inlet 2.

[0049] According to the embodiment described above, when the plug housing 4 is removed from the inlet 2, leaving the solenoid 5 behind, and the solenoid 5 moves downward, the tip of the lock pin 6 faces the inclined surface 12c in the front-rear direction. As a result, when the solenoid 5 is pulled out rearward, the tip of the lock pin 6 can be brought into sliding contact with the inclined surface 12c.

[0050] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0051] According to the above-described embodiment, the locked portion 12 has the inclined surface 12c below the locking surface 12b, but this is not limited to this. The inclined surface 12c is not essential and may be omitted. That is, a configuration may be adopted in which the lower surface 12e is provided continuous with the locking surface 12b. In this case as well, when the plug housing 4 is removed from the inlet 2, leaving the solenoid 5 behind, and the solenoid 5 moves downward, the tip of the lock pin 6 no longer faces the locked portion 12 in the front-rear direction, allowing the solenoid 5 to move rearward.
