  The electrical connector provided with the shutter of Patent Document 1 requires, for example, an independent elastic member. In comparison, the connector provided with the terminal protection plate of Patent Document 2 does not require such an elastic member, and the number of parts is reduced accordingly, but there are the following problems. Since the locking piece extends from the terminal protection plate to the fitting side and the hook piece extends from the terminal protection plate to the non-fitting side, and the locking piece and the hook piece are provided on the axis, For example, when the hook piece is displaced, the locking piece is likely to be displaced in conjunction with the hook piece. For this reason, for example, when the second connector housing is pulled out from the first connector housing, when the hook piece is disengaged from the locking recess of the second connector housing, the engagement is interlocked with the displacement of the hook piece. There is a possibility that the stopper piece is displaced and disengaged from the locking receiving portion, whereby the terminal protection plate is disengaged from the first connector housing. In order to prevent this, for example, it is conceivable to increase the thickness of the terminal protection plate to increase the rigidity, thereby preventing the hook piece and the locking piece from being displaced in conjunction with each other. Lengthens.

  The present invention has been made paying attention to such a point, and an object of the present invention is to provide a pair of electrical connectors provided with a shutter on one side, which can solve the above problems. .

To achieve the above object, a first pair of electrical connectors according to the present invention, each having a shutter, is fitted with the first electrical connector and the first electrical connector so as to be detached from the first electrical connector. And a second electrical connector.
The first electrical connector includes a first housing provided with a peripheral wall so that a first housing chamber having an opening on the fitting side is formed therein;
A first contact provided in the first housing such that a contact portion is disposed in the first storage chamber;
The first housing is disposed in the first housing chamber so as to close the opening of the first housing chamber, and the fitting side of the first housing relative to the contact portion of the first contact. The first contactor is slidably provided between the first position located at the second position and the second position located on the opposite side of the contact portion with respect to at least a part of the contact portion. And a shutter provided with a first hole penetrating in the fitting / removing direction at a portion corresponding to the contact portion.
In the second electrical connector, a second housing chamber that communicates with the fitting side through a second hole penetrating in the fitting / removing direction at a portion corresponding to the first hole is formed inside, and A second housing provided with a body that receives the shutter when the electrical connector is fitted;
The contact portion includes a second contact provided on the second housing so as to be disposed in the second storage chamber corresponding to the second hole when viewed in the fitting / removing direction.
The first housing is configured by a part of the peripheral wall, extends to the fitting side, and has a width at which the fitting side end is orthogonal to the fitting / removing direction in the vicinity of the opening of the first storage chamber. A first elastic piece capable of bending in a direction is provided,
The shutter is provided with a second elastic piece that extends toward the fitting side and can bend in the width direction at the end of the fitting side, and has a flange at the end.
The first housing is provided with a locking portion that hangs from the opposite side to the flange of the second elastic piece,
One of the inner side in the width direction than the second elastic piece in the first housing and the outer side in the width direction of the main body of the second housing extends to the fitting side and extends to the fitting side. Is provided with a third elastic piece that can bend in the width direction and provided with a flange at the end, and on the other side is provided with a first convex part that protrudes in the width direction. ,
The second housing is provided with a side wall having a second convex portion that is disposed outside the width direction of the main body and protrudes inside the width direction,
The first electrical connector is provided with a stop mechanism that prevents the shutter from moving to the fitting side from the first position.
The pair of electrical connectors provided with a shutter on one side of the pair of electrical connectors, the hook of the third elastic piece gets over the first projecting portion and the reaction of the first projecting portion in the fitting process of the both electrical connectors. The second convex part of the side wall pushes the second elastic piece inward in the width direction via the first elastic piece, and the hook of the second elastic piece is pulled from the locking part. The shutter is received by the main body and moved from the first position to the second position by the movement of the first housing toward the fitting side. In the process of detaching the two electrical connectors, the third elastic piece The shutter is returned to the first position by the hook on the first convex portion, and the second convex portion of the side wall moves the second elastic piece in the width direction through the first elastic piece. Push inward to lock the hook of the second elastic piece Configured so that the hook of the third elastic piece gets over the first convex portion and returns to the fitting side of the first convex portion when the shutter is stopped at the first position by the stop mechanism. Has been.

  When the two electrical connectors are separated from each other, the locking portion is hooked on the flange of the second elastic piece from the anti-fitting side, so that the shutter is moved to the anti-fitting side from the first position. In addition, since the shutter does not move to the fitting side from the first position by the stop mechanism, the contact portion of the first contactor is isolated from the outside by the shutter. As a result, for example, the user may be touched with the contact portion to receive an electric shock, the contact portion may be subjected to an external force, and the contact portion may be deformed or damaged, or the first contactor may be electrically disturbed. It is possible to reduce the possibility of adding. Then, when one of the two electrical connectors is inserted into the other during the fitting process of the two electrical connectors, the hook of the third elastic piece gets over the first convex portion and the first convex portion The second convex part of the side wall pushes the second elastic piece inward in the width direction via the first elastic piece so that the hook of the second elastic piece is engaged with the engagement. The first contactor is moved from the first position to the second position by the movement of the first housing toward the fitting side, and the insertion is further continued. The contact portion of the first electrode exits from the first hole to the fitting side, enters the second hole, and contacts the second contactor. On the other hand, when the electrical connectors are separated in the process of detaching the electrical connectors, the hook of the third elastic piece is hooked on the first convex portion, so that the shutter returns to the first position, and The second convex portion of the side wall pushes the second elastic piece inward in the width direction through the first elastic piece to release the hook of the second elastic piece from the locking portion, and the stop mechanism Since the shutter stops at the first position and does not move further to the fitting side, the hook of the third elastic piece gets over the first convex portion and the fitting side of the first convex portion. Return to. In this case, even if the both electrical connectors are in a half-fitted state that does not completely fit, when the two electrical connectors are separated, the flange of the third elastic piece is the first convex portion. The shutter returns to the first position. The pair of electrical connectors provided with a shutter on one side can realize an embodiment in which an independent elastic member is not provided. In such a case, the number of components is reduced accordingly. In addition, the second elastic piece and the third elastic piece provided on the shutter extend in parallel to the fitting side or are distributed on both electrical connectors, so that they are provided on the axis and integrally. Therefore, even if one is displaced, the other is less likely to be interlocked. Therefore, the operation timing of the second elastic piece and the third elastic piece when one of the two electrical connectors is inserted into the other can be accurately and accurately obtained. For example, the two electrical connectors are separated from each other. Occasionally problems such as the shutter dropping off are unlikely to occur. Furthermore, since no special measures are required to increase the thickness of the shutter and increase the rigidity, the length of the first electrical connector is less likely to increase. In addition, the guide function of the second elastic piece prevents the shutter from moving obliquely inside the first housing, so that the electrical connectors are prevented from fitting obliquely.

The second pair of electrical connectors having a shutter on one side is the first pair of electrical connectors having a shutter on one side,
At least one of the surface of the first elastic piece and the surface of the two elastic pieces that are in contact with each other in the fitting process of the two electrical connectors is viewed in the thickness direction perpendicular to the fitting / removing direction and the width direction. A pair of electrical connectors provided with a shutter on one side, which is formed obliquely with respect to the fitting / removing direction and the width direction so as to approach the outside of the width direction as it goes toward the fitting side.

  For example, when the shutter is pushed to the non-fitting side by the main body of the second housing, the contact pressure between the flange of the second elastic piece and the locking portion of the first housing increases, The heel may be difficult to come off from the locking portion to the inside in the width direction. However, if the second electrical connector having a shutter on one side is used, when one of the two electrical connectors is inserted into the other, the surface of the first elastic piece and the second elastic connector are inserted. When the surface of the piece comes into contact with the first elastic piece, a force pushing the second elastic piece inward in the width direction acts on the second elastic piece, so that the flange of the second elastic piece and the first housing Even if a contact pressure is applied to the locking part, the hook is easily detached from the locking part to the inner side in the width direction.

The third crimp terminal is a pair of electrical connectors provided with a shutter on one side of the first or the second,
The stop mechanism is provided in the first housing, and protrudes inward in the width direction;
A pair of electrical connectors provided on the shutter and provided with a shutter engaging portion that is hooked on the third convex portion from the non-fitting side on one side.

  In this case, since the third convex portion is engaged with the shutter locking portion in the process of detaching both the electrical connectors, the shutter stops at the first position and does not move to the fitting side. For this reason, the flange of the third elastic piece gets over the first convex portion and returns to the fitting side of the first convex portion. Further, the shutter is prevented from coming off from the first housing to the fitting side.

A fourth pair of electrical connectors provided with a shutter on one side is a pair of electrical connectors provided with a shutter on one side among the first to third,
The first elastic piece, the second elastic piece, the third elastic piece or the first convex portion, and the locking portion are arranged in the width direction across the central portion of the first electric connector in the width direction. Provided on both sides,
Correspondingly, the first convex portion or the third elastic piece, and the side wall having the second convex portion are arranged on both sides in the width direction across the central portion in the width direction of the second electrical connector. A pair of electrical connectors provided with a shutter on one side.

  In this way, the operation of the two electrical connectors is balanced with respect to the center in the width direction of the two electrical connectors. Generation of force and the like is prevented.

A fifth pair of electrical connectors provided with a shutter on one side is a pair of electrical connectors provided with a shutter on one side among the first to fourth,
In the fitting process of the two electrical connectors, after the flange of the third elastic piece gets over the first convex part and hits the anti-fitting side of the first convex part, the second convex of the side wall When the part pushes the second elastic piece inward in the width direction through the first elastic piece, the flange of the second elastic piece comes off from the locking part, After the second convex portion of the second elastic piece pushes the second elastic piece inward in the width direction through the first elastic piece to release the flange of the second elastic piece from the locking portion, the third elastic piece It is a pair of electrical connectors provided with a shutter on one side, which is configured such that the hook of the piece gets over the first convex part and returns to the fitting side of the first convex part.

  In this way, when the two electrical connectors are separated from the half-fitted state where the two electrical connectors do not completely fit, the first connector can be used even when the fitting depth is relatively shallow. The shutter returns to the first position by the hook of the three elastic pieces being hooked on the first convex portion.

  The pair of electrical connectors provided with the shutter on one side of the first aspect of the present invention is, for example, the possibility that a user touches the contact portion to receive an electric shock, the contact portion is deformed by an external force applied to the contact portion The possibility of being damaged or the possibility of electrical disturbance being applied to the first contact can be reduced, and when an independent elastic member is not provided, the number of parts is reduced accordingly. In addition, the operation timing of the second elastic piece and the third elastic piece when one of the electric connectors is inserted into the other can be obtained accurately and accurately. For example, the electric connectors are separated from each other. When this occurs, problems such as the shutter dropping off are unlikely to occur. Furthermore, there is little possibility that the length of the first electrical connector will be long. In addition, the guide function of the second elastic piece can prevent the two electrical connectors from being fitted obliquely.

  The second pair of electrical connectors provided with a shutter on one side according to the present invention provides the effects obtained by the first pair of electrical connectors provided with a shutter on one side, Even if contact pressure is applied to the hook of the two elastic pieces and the locking portion of the first housing, the hook can be easily detached from the locking portion to the inside in the width direction.

  In addition to obtaining the effect obtained by the first or the second pair of electrical connectors provided with a shutter on one side, the third pair of electrical connectors provided with the shutter on one side of the present invention, Furthermore, an example of the stop mechanism could be specifically shown.

  According to the fourth aspect of the present invention, the pair of electrical connectors provided with a shutter on one side can obtain an effect obtained by the pair of electrical connectors provided with a shutter on one side among the first to third aspects. In addition, the operation of the two electrical connectors is balanced with the center of the two electrical connectors as the center. Occurrence can be prevented.

  According to the fifth aspect of the present invention, the pair of electrical connectors provided with a shutter on one side has the effect obtained by the pair of electrical connectors provided with one of the first to the fourth and the shutter on one side. In addition, when the electrical connectors are separated from the half-fitted state where the electrical connectors do not completely fit together, the above-mentioned electrical connectors can be used even when the fitting depth is relatively shallow. The shutter can be returned to the first position.

The second convex portion 212a of the side wall 212 pushes the second elastic piece 132 inward in the width direction via the first elastic piece 114, and the second convex portion 212d is pushed to the opposite side of the first convex portion 211d. The hook 132a of the elastic piece 132 is disengaged from the locking portion 115, the shutter 130 is received by the main body 211, and the first housing 110 moves to the fitting side from the first position to the second position. In the process of detaching both the electrical connectors 100 and 200, the shank 133a of the third elastic piece 133 is hooked on the first convex portion 211d, so that -130 returns to the first position, and the second convex portion 212a of the side wall 212 pushes the second elastic piece 132 inward in the width direction via the first elastic piece 114, thereby the second elastic piece 132. The hook 132a is released from the locking portion 115, and the shutter 130 is stopped at the first position by the stop mechanism, so that the hook 133a of the third elastic piece 133 gets over the first convex portion 211d and It is comprised so that it may return to the said fitting side of the 1st convex part 211d. The operation in the above-mentioned fitting process starts from the state shown in FIGS. 5 to 7, passes through the state shown in FIGS. 8 to 10, the state shown in FIGS. 11 to 13, and the state shown in FIGS. 14 to 16. On the contrary, the operation in the above-described separation process starts from the state of FIGS. 14 to 16, goes through the states of FIGS. 11 to 13, and FIGS. 8 to 10, and FIGS. This is indicated by the change in the group of four drawings leading to state 7.

  In the case of this embodiment, at least one of the surfaces of the first elastic piece and the second elastic piece that are in contact with each other in the fitting process of the two electrical connectors is viewed in the thickness direction. It is formed obliquely with respect to the fitting / removing direction and the width direction so as to approach the outer side in the width direction toward the mating side. Here, both the surface 114a of the first elastic piece 114 and the surface 132b of the second elastic piece 132, which are in contact with each other in the fitting process of the two electrical connectors 100 and 200, are fitted when the fitting direction is viewed in the thickness direction. It is formed obliquely with respect to the fitting / removing direction and the width direction so as to approach the outer side in the width direction toward the mating side. However, even if it is not both surfaces in this way, only one of the above-mentioned surfaces will be fitted to the outer side in the width direction as it goes to the fitting side when viewed in the thickness direction. It may be formed obliquely with respect to the separation direction and the width direction.

  In the case of this embodiment, as shown in FIGS. 17 to 19, the stop mechanism is provided in the first housing 110, and is provided in the third protrusion 116 protruding inward in the width direction and the shutter 130. In addition, the third convex portion 116 is provided with a shutter locking portion 134 that is hooked from the non-fitting side. The third protrusion 116 is provided on the peripheral wall 111 so as to protrude inward in the width direction. The shutter locking portion 134 is provided at the outer end of the shutter 130 in the width direction, and extends toward the fitting side so that the end of the fitting side can bend in the width direction. Is provided at the end. When the shutter 130 is in the first position, the first shutter locking portion 134 is in contact with the portion of the third convex portion 116 on the side opposite to the fitting side. However, the third convex portion may be provided at another part of the first handling. Further, the shutter locking portion may be provided at another part of the shutter.

  In the case of this embodiment, the first elastic piece 114, the second elastic piece 132, the third elastic piece 133, and the locking portion 115 sandwich the central portion of the first electrical connector 100 in the width direction. And provided on both sides in the width direction. Correspondingly, the side wall 212 having the first convex portion 211d and the second convex portion 212a has both sides in the width direction across the central portion in the width direction of the second electrical connector 200. Is provided. Contrary to this embodiment, when the first protrusion is provided on the first housing and the third elastic piece is provided on the second housing, the first elastic piece, the second elastic piece, The first convex portion and the locking portion are provided on both sides in the width direction across the central portion in the width direction of the first electrical connector, and correspondingly, the third elastic piece, and the above You may provide the said side wall which has a 2nd convex part in the both sides of the said width direction on both sides of the center part of the said width direction of the said 2nd electrical connector.

  In the case of this embodiment, in the fitting process of the two electrical connectors 100 and 200, the flange 133a of the third elastic piece 133 gets over the first convex portion 211d and the anti-fitting of the first convex portion 211d. After being hooked to the side, the second protrusion 212a of the side wall 212 pushes the second elastic piece 132 inward in the width direction via the first elastic piece 114, and the flange 132a of the second elastic piece 132 Is disengaged from the locking portion 115, and in the process of detaching the two electrical connectors 100, 200, the second convex portion 212a of the side wall 212 causes the second elastic piece 132 to move to the width through the first elastic piece 114. After pushing the hook 132a of the second elastic piece 132 away from the locking portion 115 by pushing inward in the direction, the hook 133a of the third elastic piece 133 gets over the first convex portion 211d. It is configured to return to the fitting side of the first convex portion 211d.

  Therefore, in the pair of electrical connectors provided with the shutter in one of the embodiment and the modification thereof, when the two electrical connectors 100 and 200 are separated from each other, the flange 132a of the second elastic piece 132 is in contact with the flange 132a. Since the engaging portion 115 is engaged from the opposite side, the shutter 130 does not move to the opposite side from the first position, and the shutter 130 is moved from the first position by the stop mechanism. Since it does not move to the mating side, the contact portion 121 of the first contactor 120 is isolated from the outside by the shutter 130. Accordingly, for example, the user may be touched with the contact part 121 to receive an electric shock, the external force may be applied to the contact part 121, the contact part 121 may be deformed or damaged, or the first contactor 120 may be damaged. The possibility that an electrical disturbance is applied can be reduced. When one of the electrical connectors 100 and 200 is inserted into the other during the fitting process of the electrical connectors 100 and 200, the flange 133a of the third elastic piece 133 is moved to the first convex portion 211d. And the second convex portion 212a of the side wall 212 passes the first elastic piece 114 through the first elastic piece 114 to the inner side in the width direction. And the flange 132a of the second elastic piece 132 is disengaged from the locking portion 115, the shutter 130 is received by the main body 211, and the first housing 110 is moved to the fitting side to move to the first position. When the insertion is further continued from the first position to the second position, the contact portion 121 of the first contactor 120 comes out from the first hole 131 to the fitting side and the second hole 21. It enters c, to contact with the second contact element 220. On the other hand, when the electric connectors 100 and 200 are separated in the process of detaching the electric connectors 100 and 200, the hook 133a of the third elastic piece 133 is hooked on the first convex portion 211d. 130 returns to the first position, and the second convex portion 212a of the side wall 212 pushes the second elastic piece 132 inward in the width direction via the first elastic piece 114, and the second elastic piece 132 The hook 132a is released from the locking portion 115, and the shutter 130 is stopped at the first position by the stop mechanism and does not move further toward the fitting side. Therefore, the hook of the third elastic piece 133 is not moved. 133a gets over the first convex portion 211d and returns to the fitting side of the first convex portion 211d. In that case, even if the both electrical connectors 100 and 200 are in a half-fitted state where the electrical connectors 100 and 200 are not completely fitted, when the both electrical connectors 100 and 200 are separated, the third elastic piece 133 is Since the hook 133a is hooked on the first convex portion 211d, the shutter 130 returns to the first position. The pair of electrical connectors provided with a shutter on one side can realize an embodiment in which an independent elastic member is not provided. In such a case, the number of components is reduced accordingly. In addition, the second elastic piece 132 and the third elastic piece 133 provided on the shutter 130 extend in parallel to the fitting side or are distributed on both the electrical connectors 100 and 200, so Moreover, since it does not take the form of being provided integrally, even if one is displaced, there is little possibility that the other interlocks. Therefore, the operation timing of the second elastic piece 132 and the third elastic piece 133 when one of the electric connectors 100 and 200 is inserted into the other can be obtained accurately and accurately. When the connectors 100 and 200 are separated, problems such as the shutter 130 dropping off are unlikely to occur. Further, since no special measures are required to increase the thickness of the shutter 130 to increase the rigidity, there is little possibility that the length of the first electrical connector 100 will be increased. In addition, the guide function of the second elastic piece 132 prevents the shutter 130 from moving obliquely inside the first housing 110, so that both the electrical connectors 100 and 200 are fitted obliquely. Is prevented.

  The pair of electrical connectors provided with a shutter on one side according to the present invention does not limit the shape of the surface of the first elastic piece and the surface of the second elastic piece which are contacted in the fitting process of the two electrical connectors. Among such various embodiments, in the case of a pair of electrical connectors provided with a shutter on one side of the above-described embodiment and the above-described modification, the above-mentioned first contact is made in the fitting process of both the electrical connectors 100, 200. At least one of the surface 114a of the first elastic piece 114 and the surface 132b of the second elastic piece 132 is closer to the outer side in the width direction toward the fitting side when viewed in the thickness direction. It is formed obliquely with respect to the fitting / removing direction and the width direction. For example, when the shutter 130 is pushed to the non-fitting side by the main body 211 of the second housing 210, the hook 132a of the second elastic piece 132 and the locking portion 115 of the first housing 110 are connected. The contact pressure increases, and the shutter 130 may not easily come off the locking portion 115 inward in the width direction. However, according to the embodiment and the modification thereof, when one of the electrical connectors 100 and 200 is inserted into the other, the surface 114a of the first elastic piece 114 and the second elastic piece 132 When the surface 132b comes into contact, a force that pushes the first elastic piece 114 toward the inner side in the width direction acts on the second elastic piece 132. Therefore, the flange 132a of the second elastic piece 132 and the above-mentioned Even if a contact pressure is applied to the locking portion 115 of the first housing 110, the hook 132a is easily detached from the locking portion 115 to the inside in the width direction.

  The stop mechanism of a pair of electrical connectors provided with a shutter on one side of the present invention is provided in the first electrical connector, and prevents the shutter from moving to the fitting side from the first position. Any mechanism can be used. Among such various embodiments, in the case of a pair of electrical connectors provided with a shutter on one side of the embodiment and the modified example, the stop mechanism is provided in the first housing 110, and the width A third convex portion 116 protruding inward in the direction, and a shutter engaging portion 134 provided on the shutter 130 and hooking the third convex portion 116 from the opposite side. In this case, the third convex portion 116 is engaged with the shutter locking portion 134 in the process of detaching both the electrical connectors 100 and 200, so that the shutter 130 stops at the first position and is more Since it does not move to the fitting side, the flange 133a of the third elastic piece 133 gets over the first convex portion 211d and returns to the fitting side of the first convex portion 211d. Further, the shutter 130 is prevented from coming off from the first housing 110 to the fitting side.

  In the case of a pair of electrical connectors according to the present invention having a shutter on one side, the first elastic piece, the second elastic piece, the third elastic piece or the first convex part, and the locking part are the first One set or two or more sets are provided in one electrical connector, and correspondingly, the first convex portion or the third elastic piece and the side wall having the second convex portion are provided on the second electrical connector. It is sufficient that the same number of sets as the number of sets is provided. Among such various embodiments, in the case of a pair of electrical connectors provided with a shutter on one side of the above embodiment and the above modification, the first elastic piece 114, the second elastic piece 132, the first Three elastic pieces 133 or the first convex portions and the locking portions 115 are provided on both sides of the width direction of the first electrical connector 100 with the width direction center portion therebetween, correspondingly, The side wall 212 having the first convex portion 211d or the third elastic piece and the second convex portion 212a is provided on both sides in the width direction of the second electrical connector 200 with the central portion in the width direction interposed therebetween. It has been. In this way, the operation of the two electrical connectors 100, 200 is balanced with the center of the width direction of the two electrical connectors 100, 200 as the center. For example, the two electrical connectors 100, 200, It is possible to prevent a twisting force or the like from being generated when the 200 is fitted or detached.

  In the case of a pair of electrical connectors provided with a shutter on one side of the present invention, the timing at which the flange of the third elastic piece gets over the first convex portion and is applied to the opposite side of the first convex portion, and Of the timings at which the second convex portion of the side wall pushes the second elastic piece inward in the width direction through the first elastic piece, and the heel of the second elastic piece is released from the locking portion. There is no limitation on whether the timing is first. Among such various embodiments, in the case of a pair of electrical connectors provided with a shutter on one side of the above embodiment and the modified example, the third elastic piece 133 is used in the fitting process of the both electrical connectors. After the collar 133a gets over the first convex portion 211d and hits the opposite side of the first convex portion 211d, the second convex portion 212a of the side wall 212 passes through the first elastic piece 114. Then, the second elastic piece 132 is pushed inward in the width direction so that the hook 132a of the second elastic piece 132 is detached from the locking portion 115, and in the process of detaching the two electrical connectors 100, 200, The second convex portion 212a pushes the second elastic piece 132 inward in the width direction through the first elastic piece 114, and the hook 132a of the second elastic piece 132 is removed from the locking portion 115. After is, the hook 133a of the third elastic piece 133 is configured to return to the fitting side of the first convex portion 211d climbs over the first protrusion 211d. In this way, when the electrical connectors 100 and 200 are separated from the half-fitted state where the electrical connectors 100 and 200 are not completely engaged, the fitting depth is relatively shallow. Even so, the shutter 130 returns to the first position by the hook 133a of the third elastic piece 133 engaging the first convex portion 211d.

  When the shutter is formed of a material having a high waterproof property such as rubber, thermoplastic elastomer, or other elastomer, there is a possibility that the first contactor has a waterproof function.
