Description

The present invention relates to a connector having a shutter mechanism.

2. Description of the Related Art Conventionally, a wire harness (electric wire) for electrically connecting various electrical components mounted in an automobile or the like is connected by a connector. Such connectors typically consist of a male connector and a female connector. And, for example, in the case of a connector structure applied to optional specifications, one connector connected to the end of a pre-arranged electric wire is dust-proof, terminal-protected, and surrounded by the other connector until the other connector is mated. It is known to provide a shutter mechanism at the front opening of the housing for the purpose of preventing electric shock to the housing. In particular, in electric vehicles and the like, a connector (inlet) with a shutter mechanism is applied to prevent electric shock accidents, etc., and prevents exposure of terminals at a front opening when the connector is not connected. As an example of such a configuration, there is a connector with a shutter mechanism disclosed in Patent Document 1, for example.

In this connector with a shutter mechanism, one connector is provided with a shutter that rotates outward when an external force is applied to the front surface thereof, and the other connector is provided with a tip portion, so that when the connectors are mated, the tip portion of the shutter rotates outward. The shutter is rotated by pressing the front surface of the shutter of the connector.

JP-A-8-138785

By the way, in the connector with a shutter mechanism disclosed in Patent Document 1, when the connector is mated, the tip of the mating connector (fitting hood) presses the front face of the shutter, causing the shutter to move outward (forward) around the pin. ) to open. Therefore, it is necessary to avoid interference during connector fitting by setting the stroke (connector size) of the mating connector in consideration of the rotational locus of opening of the shutter. Therefore, the mating hood portion of the mating connector is lengthened by the opening/closing space of the shutter, and the size of the connector is increased.

The shutter is always urged toward the inside of the housing by a coil spring, and is configured to close the front opening of the housing when the connector is not connected. A torsion coil spring wound around a pin that supports the shutter is used as the coil spring that always urges the shutter in the closing direction. Therefore, the coil spring is positioned near the front opening of the housing, and is easily affected by dust, water, and the like. Therefore, conventional connectors with a shutter mechanism tend to have a high risk of spring malfunction.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a compact connector while ensuring the spring function of a connector with a shutter mechanism.

The above objects of the present invention are achieved by the following configurations.
(1) First cam grooves are formed through a housing that accommodates connection terminals, an outer case that accommodates and holds the housing, and side walls of the movable case corresponding to both side walls of the outer case. a movable case arranged movably in a fitting direction; a shutter front wall covering a front opening of the housing into which the mating connector is fitted; shutter side walls provided at both ends of the shutter front wall; a shutter having a shutter boss projecting from the outer surface of a side wall and engaging with the first cam groove; and a spring for elastically biasing the movable case toward the mating connector, the first cam groove (2) engages with the shutter boss to rotate the shutter in the opening/closing direction around the shutter boss in conjunction with movement of the movable case.

According to the connector having the configuration (1) above, the tip of the mating connector rotates the shutter in the opening/closing direction via the movable case arranged to be movable in the connector fitting direction within the outer case. Therefore, in the connector of this configuration, unlike the conventional connector with a shutter mechanism, it is not necessary to lengthen the mating hood portion of the mating connector in consideration of the opening/closing trajectory of the shutter.

(2) Provided on both side walls of the outer case and engaged with the shutter bosses to move the shutters with respect to the outer case along the connector fitting direction in conjunction with the movement of the movable case. a third cam groove of the movable case, a movable case boss protruding from the inner surface of the movable case side wall of the movable case, and the movable case boss formed on the shutter side wall of the shutter. The connector according to (1) above, further comprising a second cam groove that supports the rotational movement of the shutter that moves along the mating direction.

According to the connector having the above configuration (2), when the mating connector is mated, the shutter whose rotation is supported by the engagement of the movable case boss with the second cam groove rotates smoothly in the opening direction. can move to the rear of the outer case together with the movable case. Therefore, the shutter can easily prevent interference with the mating connector, and the degree of freedom in design can be enhanced.

(3) The third cam groove is engaged with the third cam groove so that the front wall of the shutter is displaced toward the shutter boss while the shutter rotates from the shutter closed position to the shutter open position. The connector according to (2) above, further comprising a third displacement cam portion that moves the shutter via the shutter boss.

According to the connector having the configuration (3) above, when the shutter is opened, the front wall of the shutter, which is the leading end (free end) of rotation, is displaced toward the shutter boss, which is the center of rotation, by the third displacement cam portion of the third cam groove. Let me. Therefore, when the shutter is opened, the front wall of the shutter does not protrude outside the outer case, and the connector can be made compact when the shutter is opened.

(4) The first cam groove extends in a direction intersecting with the third displacement cam portion in a side view, and cooperates with the third displacement cam portion just before the shutter rotates from the shutter closed position to the shutter open position. The connector according to (3) above, further comprising a first displacement cam portion that functions to displace the shutter boss toward the mating connector along the connector fitting direction.

According to the connector having the above configuration (4), immediately before the shutter rotates from the shutter closed position to the shutter open position, the first cam groove extending in the direction intersecting with the third displacement cam portion when viewed from the side faces the first displacement. The cam portion displaces the shutter front wall toward the mating connector along the connector fitting direction via the shutter boss. Therefore, the shutter can be configured so that the front wall of the shutter covers the front opening while being in contact with the opening edge of the front opening in the shutter closed position.
That is, immediately before the shutter rotates from the state in which the shutter front wall is in contact with the opening edge of the front opening to the shutter open position, the shutter front wall is displaced toward the mating connector side and separated from the opening edge of the front opening. Therefore, the front wall of the shutter rotating to the shutter open position is not rubbed against the edge of the front opening.
As a result, the shutter front wall of the shutter that covers the front opening while in contact with the opening edge can reliably prevent dust, water, and the like from entering the front opening of the housing.

(5) The second cam groove supports the displacement operation of the shutter displaced toward the mating connector along the connector fitting direction immediately before the shutter rotates from the shutter closed position to the shutter open position. The connector according to (4) above, characterized in that a two-displacement cam portion is provided.

According to the connector having the above configuration (5), the shutter displaced toward the mating connector along the connector fitting direction immediately before rotating from the shutter closed position to the shutter open position is such that the movable case boss is positioned at the second position of the second cam groove. Displacement motion is supported by engaging two-displacement cam portions. Therefore, the shutter that is displaced toward the mating connector along the connector fitting direction can be displaced while maintaining a posture parallel to the connector fitting direction, and the front wall of the shutter is positioned against the opening edge of the front opening. It is possible to prevent uneven contact (strong contact at part of the opening edge).

(6) the shutter front wall includes an elastic packing that abuts against the opening edge of the front opening;
The connector according to (4) or (5) above, characterized in that:

According to the connector having the configuration (6) above, the elastic packing provided on the front wall of the shutter can elastically contact the edge of the front opening. Therefore, the elastic packing that covers the front opening by coming into contact with the edge of the opening can more reliably prevent dust, water, and the like from entering the front opening of the housing.

(7) The connector according to any one of (1) to (6) above, wherein the spring is interposed between the movable case and the rear wall of the housing.

According to the connector of configuration (7) above, the spring that elastically urges the movable case toward the mating connector is arranged on the rear wall side of the housing accommodated and held in the outer case, and the opening of the outer case (the fitting of the housing). away from the opening). Therefore, the spring arranged in the outer case apart from the opening is less susceptible to dust, water, etc., and the spring function of the connector with the shutter mechanism can be easily guaranteed.

(8) An abutting portion that is pressed against the tip of the mating connector when the connectors are mated is provided at the front end of the intersecting portion between the side wall of the movable case and the upper wall of the movable case. A connector according to any one of the above (1) to (7).

According to the connector of the above configuration (8), the tip of the mating connector presses and biases the abutment provided at the front end of the intersection between the side wall of the movable case and the upper wall of the movable case, which have relatively high rigidity. Therefore, the movable case, which is pressed against the tip of the mating connector when the connectors are mated, is less likely to be deformed due to the pressing force of the mating connector, and the thickness of the movable case need not be increased more than necessary.

When the movable case 31 moves rearward on the side opposite to the inlet plug 5 (right side in FIG. 9) with respect to the outer case 51 , the shutter boss 47 reaches the first rotary cam portion 37 b of the first cam groove 37 . Then, the second cam groove 48 engages (follows) the movable case boss 38 , and the shutter 41 , whose rotation is supported when it moves along the connector fitting direction, moves toward the shutter boss 47 . is rotated downward.

From this state, when the inlet plug 5 is further inserted into the inlet 1 so as to be advanced rearward, the shutter 41 is moved toward the shutter front wall 43 as shown in FIGS. is rotated to the shutter open position in which is parallel to the bottom wall 56 of the outer case 51 . Then, when the shutter boss 47 reaches the parallel portion 65 of the third cam groove 60, the shutter 41 is translated to the rear of the outer case 51 while being rotated to the shutter open position.
The connection terminal 90 of the inlet plug 5 is fitted and connected to the connection terminal 70 of the inlet 1, whereby the high voltage cable 71 and the high voltage cable 91 are electrically connected.
Therefore, the inlet 1 and the inlet plug 5 are fitted together and electrically connected by abutting the tip of the movable case 31 and the tip of the plug housing 81 .

As described above, according to the inlet 1 according to the first embodiment, the distal end portion of the inlet plug 5 moves through the shutter 41 through the movable case 31 which is arranged movably in the connector fitting direction within the outer case 51 . in the open/close direction. Therefore, in the inlet 1 of the first embodiment, unlike the conventional connector with a shutter mechanism, it is not necessary to lengthen the fitting hood portion of the inlet plug in consideration of the opening/closing trajectory of the shutter.

The inlet 1 according to the first embodiment is provided on both side walls of the outer case 51 and engages with the shutter bosses 47 to move the shutter 41 relative to the outer case 51 in conjunction with the movement of the movable case 31.

Therefore, according to the inlet 1 of the first embodiment, when the inlet plug 5 is fitted, the shutter 41 whose rotation is supported by the engagement of the movable case boss 38 with the second cam groove 48 is opened. It can move to the rear of the outer case 51 together with the movable case 31 while smoothly rotating in the direction. Therefore, the shutter 41 can be easily prevented from interfering with the inlet plug 5, and the degree of freedom in design can be enhanced.

Further, the third cam groove 60 of the inlet 1 according to the first embodiment is provided with a A third displacement cam portion 63 is provided for moving the shutter 41 via the shutter boss 47 engaged (driven) by the third cam groove 60 .

Therefore, according to the inlet 1 of the first embodiment, when the shutter is opened, the shutter front wall 43, which is the tip of rotation (free end), is moved by the third displacement cam portion 63 of the third cam groove to the shutter which is the center of rotation. It is displaced to the boss 47 side (upper side). Therefore, when the shutter is opened, the shutter front wall 43 does not protrude downward (outward) from the outer case 51, and the inlet 1 can be made compact when the shutter is opened.

Further, the spring 30 in the inlet 1 according to the first embodiment is interposed between a spring receiving portion 34 provided at the rear end of the movable case 31 and a spring support portion 27 provided at the rear wall of the housing 21. there is
Therefore, according to the inlet 1 of the first embodiment, the spring 30 that elastically urges the movable case 31 toward the inlet plug 5 is arranged on the rear wall side of the housing 21 accommodated and held in the outer case 51 . Leave the opening 3 of the case 51 (the front opening 25 of the housing 21). Therefore, the spring 30 arranged in the outer case 51 apart from the opening 3 is less likely to be affected by dust, water, etc., and it is easy to guarantee the spring function of the connector with the shutter mechanism.

Further, in the inlet 1 according to the first embodiment, when the connector is fitted, the contact portion 39 that is pressed and biased by the pressing portion 87 at the tip portion of the inlet plug 5 is attached to the movable case side walls 35 , 35 of the movable case 31 . and the upper wall 33 of the movable case.
Therefore, according to the inlet 1 of the first embodiment, the pressing portion 87 at the tip of the inlet plug 5 is positioned at the front end of the intersection between the relatively rigid movable case side walls 35, 35 and the movable case upper wall 33. The provided contact portion 39 is pressed and biased. Therefore, the movable case 31, which is pressed against the tip of the inlet plug 5 when the connector is fitted, is less likely to be deformed by the pressing force of the inlet plug 5, and the thickness of the movable case 31 needs to be increased more than necessary. Gone.

FIG. 12 is a perspective view of a movable case 31A with a shutter 41A mounted thereon separated from an outer case 51 of an inlet 1A constituting a connector according to the second embodiment of the present invention. FIG. 13 is a rear perspective view of the movable case 31A and the shutter 41A shown in FIG.
The inlet 1A according to the second embodiment uses an outer case 51A, a movable case 31A and a shutter 41A instead of the outer case 51, the movable case 31 and the shutter 41 in the inlet 1 of the first embodiment described above. Other than that, the configuration is the same as that of the inlet 1 of the first embodiment. Therefore, the same reference numerals are given to the structural members that are substantially the same as those of the inlet 1 of the first embodiment, and detailed description thereof will be omitted.

As shown in FIG. 12, the outer case 51A of the inlet 1A according to the second embodiment includes a first housing 52, a second housing 53, and a top plate 50 (not shown).
A third cam groove 60 for following and guiding a shutter boss 47 of the shutter 41A, which will be described later, is formed through the side walls 54 and 55 of the outer case 51A along the connector fitting direction.

As shown in FIGS. 12 and 13, first cam grooves are formed through the movable case side walls 35, 35 of the movable case 31A. The first cam groove 37A is formed by an elongated hole that curves and extends in the front-rear direction of the movable case 31A.
The first cam groove 37A extends from the intermediate portion of the first cam groove 37A to the rear side (the right side in FIG. 13), intersects the third displacement cam portion 63 in a side view, and extends diagonally upward (the right diagonal in FIG. 13). A first displacement cam portion formed by a curved portion extending upward) and a horizontal portion, and a curved portion formed by a curved portion extending obliquely upward (diagonally upward to the left in FIG. 13) continuously from the front end of the first displacement cam portion. and a first rotating cam portion 37b.

The shutter front wall 43 of the shutter 41A includes an elastic packing 49 that abuts against the opening edges 25a of the front openings 25 of the pair of terminal housing cylinders 23, 23, as shown in FIG. The elastic packing 49 is molded from an elastic member such as a rectangular sheet of sponge or rubber, and is integrally provided on the inner surface of the shutter front wall 43 .
That is, the shutter 41A and the pair of terminal housing cylinders 23, 23 are configured to cover the front opening 25 with the shutter front wall 43 in contact with the opening edge 25a of the front opening 25 at the shutter closed position. .

In the shutter side wall 45 , a second cam groove 48</b>A that engages with the movable case boss 38 of the movable case 31 is formed by an elongated hole that bends and extends in a direction orthogonal to the shutter front wall 43 .
The second cam groove 48A includes a second rotating cam portion 48a extending rearward (rightward in FIG. 13) from an intermediate portion of the second cam groove 48A, and an oblique portion continuing to the front end of the second rotating cam portion 48a. and a second displacement cam portion 48b extending downward (diagonally downward to the left in FIG. 13).
Therefore, the shutter 41A is attached to the movable case 31A with the shutter bosses 47 engaged with the corresponding first cam grooves 37A and the second cam grooves 48A engaged with the corresponding movable case bosses 38A.

Next, the functions of the first cam groove 37A of the movable case 31A, the second cam groove 48A of the shutter 41A, and the third cam groove 60 of the outer case 51A will be described.
FIG. 14 is an enlarged side view of the main part of the inlet 1A shown in FIG. 12, with a part broken away. FIG. 15 is a vertical cross-sectional view of the central portion of the inlet 1A shown in FIG.

When the inlet 1A and the inlet plug 5 are not fitted together, as shown in FIGS. 14 and 15, the movable case 31A is moved toward the inlet plug 5 with respect to the outer case 51A by the elastic biasing force of the spring 30 (in FIG. left). At this time, the shutter boss 47 is positioned at the horizontal portion of the first displacement cam portion in the first cam groove 37A, and its tip portion is positioned at the front end portion of the third displacement cam portion 63 in the third cam groove 60 .
Therefore, the shutter 41A, in which the second displacement cam portion 48b of the second cam groove 48A is engaged with the movable case boss 38, is designed so that the elastic packing 49 of the shutter front wall 43 is positioned so that the opening edge of the front opening 25 of the terminal accommodating cylindrical portion 23 is pushed. 25a to cover the front opening 25 of the housing 21 (see FIG. 15).

Then, when the movable case 31A moves against the elastic biasing force of the spring 30 to the side opposite to the inlet plug 5 (to the right in FIG. 15) with respect to the outer case 51A, the shutter boss 47 of the shutter 41A first moves to the first position. It reaches the curved portion of the first displacement cam portion in the cam groove 37A. Then, the shutter boss 47 is squeezed by the third displacement cam portion 63 of the third cam groove 60 and the first displacement cam portion of the first cam groove 37A, and is displaced toward the inlet plug 5 along the connector fitting direction. Let me. Then, the second displacement cam portion 48 b of the second cam groove 48 , which is inclined forward and obliquely downward in accordance with the inclination of the curved portion of the first displacement cam portion, engages (follows) the movable case boss 38 . Therefore, the shutter 41A, whose displacement toward the inlet plug 5 is supported by the movable case 31A, maintains a posture parallel to the connector fitting direction (the extending direction of the shutter side walls 45, 45 is aligned with the connector fitting direction). direction), it can be displaced diagonally forward and downward along the inclination of the curved portion of the first displacement cam portion.

Further, when the movable case 31A moves to the side opposite to the inlet plug 5 with respect to the outer case 51A, the shutter boss 47 reaches the front end of the first displacement cam portion in the first cam groove 37A, and the tip portion moves toward the third cam. A reference portion 61 in the groove 60 is reached. Then, the shutter 41A supported by the displacement operation of being displaced toward the inlet plug 5 by engaging (following) the second rotating cam portion 48a of the second cam groove 48 with the movable case boss 38 moves in the connector fitting direction. 15 obliquely downward (diagonally downward left in FIG. 15) toward the inlet plug 5 side.

Further, when the movable case 31A moves to the side opposite to the inlet plug 5 with respect to the outer case 51A, the shutter boss 47 reaches the first rotating cam portion 37b of the first cam groove 37A. Then, the second cam groove 48 engages (follows) the movable case boss 38 , and the shutter 41 , whose rotation is supported when it moves along the connector fitting direction, moves toward the shutter boss 47 . is rotated downward to the shutter open position.

When the movable case 31 moves to the side opposite to the inlet plug 5 (to the right in FIG. 15) with respect to the outer case 51 , the shutter boss 47 reaches the third displacement cam portion 63 of the third cam groove 60 . Therefore, in the shutter 41 rotated to the shutter open position, the shutter front wall 43, which is the leading end (free end) of the rotation, is displaced toward the shutter boss 47 (upward in FIG. 15), which is the center of rotation. The movable case 31A further moves to the side opposite to the inlet plug 5 with respect to the outer case 51A, and the shutter boss 47 reaches the parallel portion 65 of the third cam groove 60. Then, the shutter 41A moves rearward in parallel with the outer case 51A while being rotated to the shutter open position.

Next, the fitting operation of the inlet 1A and the inlet plug 5 will be described.
FIG. 16 is a diagram for explaining a state in which the inlet 1A and the inlet plug 5 are started to be fitted according to the second embodiment of the present invention, and FIG. 17 is a diagram for explaining a state immediately after the fitting of the inlet 1A and the inlet plug 5.

As shown in FIG. 16, when the inlet 1 and the inlet plug 5 are not mated, the movable case 31A is positioned on the inlet plug 5 side (left side in FIG. 16) with respect to the outer case 51A. At this time, the shutter boss 47 is positioned at the horizontal portion of the first displacement cam portion in the first cam groove 37A, and its tip portion is positioned at the front end portion of the third displacement cam portion 63 in the third cam groove 60 .

Therefore, the shutter 41A, in which the second displacement cam portion 48b of the second cam groove 48A is engaged with the movable case boss 38, is designed so that the elastic packing 49 of the shutter front wall 43 is positioned so that the opening edge of the front opening 25 of the terminal accommodating cylindrical portion 23 is pushed. 25a to cover the front opening 25 of the housing 21 (see FIG. 15).
Therefore, the connection terminal 70 of the inlet 1A is not exposed because the shutter 41A is closed. As a result, the inlet 1A is dust-proof, terminal-protected, and electric shock-proof.

From this state, the insertion and fitting of the inlet plug 5 into the inlet 1A is started. First, from the state shown in FIG. 16, the inlet plug 5 is moved toward the inlet 1A, and the insertion and fitting of the plug housing 81 into the outer case 51A is started.
At this time, as shown in FIGS. 17A and 17B, the pressing portion 87 at the tip of the plug housing 81 of the inlet plug 5 comes into contact with the contact portion 39 at the tip of the movable case 31A. The contact portion 39 is pressed against the elastic biasing force of the spring 30 .

When the movable case 31 moves rearward on the opposite side (the right side in FIG. 17) of the inlet plug 5 with respect to the outer case 51, the shutter boss 47 first moves along the curved portion of the first displacement cam portion in the first cam groove 37A. reach. Then, the shutter boss 47 is squeezed by the third displacement cam portion 63 of the third cam groove 60 and the first displacement cam portion of the first cam groove 37A, and is displaced toward the inlet plug 5 along the connector fitting direction. Let me. That is, the first displacement cam portion extends in a direction intersecting with the third displacement cam portion 63 of the outer case 51A in a side view, and the third displacement cam portion 63 extends immediately before the shutter 41A rotates from the shutter closed position to the shutter open position. , the shutter boss 47 can be displaced toward the inlet plug 5 along the connector fitting direction.
Then, the shutter 41A supported by the displacement operation of being displaced toward the inlet plug 5 by the engagement (driven) of the second displacement cam portion 48b of the second cam groove 48 with the movable case boss 38 is aligned with the connector fitting direction. It can be displaced while maintaining a parallel posture.

Further, as shown in FIGS. 18(a) and 18(b), when the movable case 31A moves to the side opposite to the inlet plug 5 with respect to the outer case 51A, the shutter boss 47 is displaced by the first displacement in the first cam groove 37A. While reaching the front end of the cam portion, the tip reaches the reference portion 61 in the third cam groove 60 . Then, the shutter 41A supported by the displacement operation of being displaced toward the inlet plug 5 by engaging (following) the second rotating cam portion 48a of the second cam groove 48 with the movable case boss 38 moves in the connector fitting direction. 18, toward the inlet plug 5 obliquely downward (diagonally downward left in FIG. 18).

Further, as shown in FIGS. 19A and 19B, when the movable case 31A moves to the side opposite to the inlet plug 5 with respect to the outer case 51A, the shutter boss 47 moves to the first position of the first cam groove 37A. It reaches the rotating cam portion 37b. Then, the second cam groove 48 engages (follows) the movable case boss 38 , and the shutter 41 , whose rotation is supported when it moves along the connector fitting direction, moves toward the shutter boss 47 . is rotated downward to the shutter open position.

Further, the shutter boss 47 reaches the third displacement cam portion 63 of the third cam groove 60 by moving the movable case 31A to the side opposite to the inlet plug 5 (right side in FIG. 19) with respect to the outer case 51A. Therefore, in the shutter 41A rotated to the shutter open position, the shutter front wall 43, which is the leading end (free end) of the rotation, is displaced toward the shutter boss 47 (upward in FIG. 19), which is the center of rotation. The movable case 31A further moves to the side opposite to the inlet plug 5 with respect to the outer case 51A, and the shutter boss 47 reaches the parallel portion 65 of the third cam groove 60. Then, the shutter 41A moves rearward in parallel with the outer case 51A while being rotated to the shutter open position.

From this state, when the inlet plug 5 is further inserted into the inlet 1 so as to be advanced rearward, as shown in FIGS. 56 is rotated to the shutter open position. When the shutter boss 47 reaches the parallel portion 65 of the third cam groove 60, the shutter 41A moves rearward in parallel with the outer case 51A while being rotated to the shutter open position.

The connection terminal 90 of the inlet plug 5 is fitted and connected to the connection terminal 70 of the inlet 1, whereby the high voltage cable 71 and the high voltage cable 91 are electrically connected.
Therefore, the inlet 1A and the inlet plug 5 are fitted and electrically connected to each other by butting the tip of the movable case 31A and the tip of the plug housing 81 together.

Therefore, in addition to the effects of the inlet 1 according to the first embodiment, according to the inlet 1A according to the second embodiment, immediately before the shutter 41A rotates from the shutter closed position to the shutter open position, the third The shutter front wall 43 is displaced toward the inlet plug 5 along the connector fitting direction via the shutter boss 47 by the first displacement cam portion of the first cam groove 37A extending in the direction intersecting the displacement cam portion 63 when viewed from the side. Let me. Therefore, the shutter 41A can be configured so that the front opening 25 is covered with the shutter front wall 43 in contact with the opening edge 25a of the front opening 25 at the shutter closed position.

That is, immediately before the shutter 41A rotates from the state in which the shutter front wall 43 contacts the opening edge 25a of the front opening 25 to the shutter open position, the shutter front wall 43 is displaced toward the inlet plug 5 and the front opening 25 is closed. away from the opening edge 25a. Therefore, the opening edge 25 a of the front opening 25 does not rub against the shutter front wall 43 rotating to the shutter open position.
As a result, the shutter front wall 43 of the shutter 41A covering the front opening 25 in contact with the opening edge 25a can reliably prevent dust, water, and the like from entering the front opening 25 of the housing 21. FIG.

Further, according to the inlet 1A according to the second embodiment, the shutter 41A displaced toward the inlet plug 5 along the connector fitting direction just before it rotates from the shutter closed position to the shutter open position. By engaging the second displacement cam portion 48b of the second cam groove 48, the displacement operation is supported. Therefore, the shutter 41A displaced toward the inlet plug 5 along the connector fitting direction can be displaced while maintaining a posture parallel to the connector fitting direction. It is possible to prevent one-sided contact (strong contact of part of the opening edge 25a) with the edge 25a.

Further, according to the inlet 1</b>A according to the second embodiment, the elastic packing 49 provided on the shutter front wall 43 can elastically contact the opening edge 25 a of the front opening 25 . Therefore, the elastic packing 49 that contacts the opening edge 25 a and covers the front opening 25 can more reliably prevent dust, water, and the like from entering the front opening 25 of the housing 21 .

According to the inlets 1 and 1A of each embodiment described above, it is possible to guarantee the spring function of the connector with the shutter mechanism and to provide a compact connector.
