Therefore, in this connector and the mating connector, it is necessary to suppress the intrusion of metal shavings between the respective fitting portions. Further, a liquid-proof member (seal member such as packing) for sealing the gap is provided between the respective fitting portions. Therefore, between the connector and the mating connector, if metal shavings intrude between the mating portions or adhere to the liquid-proof member during insertion / removal, the insertion / removal is performed. At this time, metal shavings may be dragged between the housing and the liquid-proof member, or metal shavings may remain between the housing and the liquid-proof member after the connector fitting is completed.

Therefore, an object of the present invention is to provide a connector capable of suppressing the intrusion of shavings between fitting portions.

A screw member to be formed and a dustproof member arranged between the outer peripheral surface of the fitting portion and the screw member so as to face the outer peripheral surface of the fitting portion and the screw member at intervals. When the screw portion and the mating screw portion are in the screwing start position, the dustproof member engages the connector in the contact portion in the fitting connection direction of the mating portion with respect to the mating fitting portion. The fitting is performed when the first dustproof position is in contact with the wall and covers the screw member side from the outer peripheral surface side of the fitting portion, and the fitting portion and the mating mating portion are in the fitting completion position. The contact portion is brought into contact with the connector fastening wall in the connection direction, and between the outer peripheral surface side of the fitting portion and the second dustproof position that covers the screw member side. It is characterized in that it is held in the housing so that it can be relatively moved in the mating connection direction and the opposite direction.

Here, the dustproof member is said to have the contact portion in contact with the connector fastening wall in the fitting connection direction and the screw member side covered from the outer peripheral surface side of the fitting portion. It is desirable to hold the housing in the housing so that it can be moved relative to the housing from the first dustproof position to the second dustproof position.

Further, it is desirable that the dustproof member is formed so as to cover a portion of the screw portion and the mating screw portion that protrudes from the connector fastening wall from the outer peripheral surface side of the fitting portion.

Further, the dustproof member is arranged at the contact position of the contact portion with respect to the connector fastening wall so as to face the locking portion on the mating connector side on the mating connection direction side, and the locking portion. It is desirable to have a locked portion that can be locked to.

Further, it is desirable to provide an unlocking mechanism for releasing the locked state of the locked portion with respect to the locked portion.

Further, it is desirable that the dustproof member has flexibility capable of bending in a direction orthogonal to the facing arrangement direction of the locked portion and the locked portion in the locked state.

Further, it is desirable that the fitting portion is fitted and connected to the mating portion via an annular liquid-proof member.

Further, the fitting portion has its own inner peripheral surface side fitted and connected to the outer peripheral surface side of the mating portion via the liquid-proof member attached to the outer peripheral surface of the mating mating portion in a tubular shape. It is desirable to be done.

Further, the housing includes at least an insulating housing for accommodating the terminal fittings, and a shield shell made of a metal material for accommodating at least the housing inward and having the fitting portion, and the screw. It is desirable that the member and the dustproof member be assembled to the shield shell.

The connector 1 of the present embodiment is physically and electrically connected to the terminal of the electric wire We as its terminal fitting 10, and is physically and electrically connected to the other terminal fitting 510 of the other connector 501. It is provided with a connector (Fig. 8). The connector 1 shown here includes two terminal fittings 10 attached to the terminal of the electric wire We. On the other hand, the counterparty connector 501 includes a counterparty terminal fitting 510 prepared for each terminal fitting 10 of the connector 1. One of the terminal fitting 10 and the mating terminal fitting 510 is molded as a female terminal, and the other of them is molded as a female terminal. In this example, the terminal fitting 10 is molded as a male terminal, and the mating terminal fitting 510 is molded as a female terminal.

The terminal fitting 10 and the mating terminal fitting 510 are each formed of a conductive material such as a metal material. In this example, a conductive metal plate is used as a base material, and the terminal fitting 10 and the mating terminal fitting 510 are formed by press working such as cutting and bending. The terminal fitting 10 is a male electric connection portion 11 that is physically and electrically connected to the other terminal fitting 510, and an electric wire connection portion 12 that is physically and electrically connected to the terminal of the electric wire We. And (Fig. 8). On the other hand, the mating terminal fitting 510 has a female electrical connection portion 511 that is physically and electrically connected to the electrical connection portion 11 of the terminal fitting 10 (FIG. 9).

The male electrical connection portion 11 is formed in a rectangular flat plate shape having two flat wall surfaces (first wall surface 11a and second wall surface 11b) (FIG. 8). In the electrical connection portion 11, at least one of the first wall surface 11a and the second wall surface 11b is used as a contact portion for making a physical and electrical connection with the female electrical connection portion 511. On the other hand, the female electrical connection portions 511 are arranged so as to face each other at a distance from each other, and the electrical connection portions 11 are fitted between the two contact portions (first contact portion 511a and second contact portion 511b). ) (Fig. 9). Here, by fitting the electrical connection portion 11 between the first contact portion 511a and the second contact portion 511b, the first wall surface 11a and the first contact portion 511a are brought into contact with each other, and the second wall surface 11b And the second contact portion 511b are brought into contact with each other. The electrical connection portion 11 is fitted into the electrical connection portion 511 from the side portion in the direction orthogonal to one of the four side portions forming the rectangle and along the surface direction of the first wall surface 11a and the second wall surface 11b. Let me do it.

The electric wire connecting portion 12 of this example may be crimped to the terminal of the electric wire We by crimping or the like, or may be fixed by welding or the like. Here, the electric wire connecting portion 12 is fixed to the terminal of the electric wire We by welding or the like. The electrical connection portion 11 has two side portions in a direction orthogonal to the fitting direction to the electrical connection portion 511. The electric wire connecting portion 12 is arranged on one of the two side portions in the orthogonal direction of the electric connecting portion 11, and the electric wire We is pulled out from the electric wire connecting portion 12 along the orthogonal direction. In the terminal fitting 10, the other side of the two sides of the electrical connection portion 11 in the orthogonal direction (that is, the side opposite to the electric wire connection portion 12 of the electrical connection portion 11) is referred to as a tip.

Here, the counterparty connector 501 includes a counterparty housing 520 as an accommodating component for accommodating the counterparty terminal fitting 510 (FIGS. 1 to 3, 5, 7, and 9). The counterparty housing 520 is molded from an insulating material such as synthetic resin. The mating housing 520 has a first contact accommodating portion 521 accommodating the first contact portion 511a and a second contact accommodating portion 522 accommodating the second contact portion 511b (FIGS. 2 and 9). The first contact accommodating portion 521 and the second contact accommodating portion 522 are arranged so as to face each other with a gap from each other, and the contact portions of the first contact portion 511a and the second contact portion 511b with respect to the electrical connection portion 11 are exposed. Let me. The counterparty housing 520 of this example includes a housing member 520A and a holding member 520B (FIG. 9), and the counterparty terminal fitting 510 housed in the housing member 520A is held by the holding member 520B. The counterparty housing 520 is fixed to the case 530 of the counterparty device 500 (FIGS. 1 to 7).

The connector 1 includes a housing 20 as an accommodating component for accommodating the terminal fitting 10 and the electric wire We and pulling out the electric wire We to the outside (FIGS. 1 to 8). This connector 1 is fixed to the other party connector 501 side via the housing 20 after the connector fitting with the other party connector 501 is completed. In the connector 1 of this example, the housing 20 is screwed and fixed to the connector fastening wall 531 on the mating connector 501 side by using the screw member B (FIGS. 2, FIG. 3, FIG. 5 and FIG. 7). Here, a part of the outer wall of the case 530 in the counterparty device 500 is used as the connector fastening wall 531.

The housing 20 has a tubular fitting portion 21 that fits and connects to the mating fitting portion 523 of the mating housing 520 along the tubular axis direction (FIGS. 1 to 3, 5 and 7). The fitting portion 21 and the mating mating portion 523 may be formed in a form in which the fitting portion 21 is fitted into the inner space of the mating fitting portion 523, and the mating portion 21 may be formed in the inner space of the mating portion 21. It may be formed in a form in which the mating portion 523 is fitted into the mating portion 523. Regardless of the form, the fitting portion 21 is fitted and connected to the mating fitting portion 523 via the annular liquid-proof member Se1 (FIGS. 2, FIG. 3, FIG. 5 and FIG. 7). The liquid-proof member Se1 is a sealing member such as a packing that seals an annular gap formed between the fitting portion 21 and the mating portion 523 after the fitting connection is completed.

In this example, the mating mating portion 523 is also formed in a tubular shape, and the mating mating portion 523 is coaxially fitted into the inner space of the mating portion 21. The mating housing 520 is screwed and fixed to the outer wall of the case 530 using a male screw member B1 in a state where the mating fitting portion 523 is projected outward from the outer wall (connector fastening wall 531) of the case 530 (FIG. 2). , FIG. 4 and FIG. 6). The liquid-proof member Se1 of this example is attached to the outer peripheral surface of the mating portion 523 coaxially with the mating mating portion 523. Therefore, the fitting portion 21 of this example is fitted and connected to its inner peripheral surface side to the outer peripheral surface side of the mating fitting portion 523 via the liquid-proof member Se1.

The housing 20 may be composed of only an insulating housing, or may be composed of an insulating housing and a shield shell made of a metal material. The illustrated connector 1 is configured as a so-called shield connector capable of suppressing the intrusion of noise from the outside. Therefore, the housing 20 shown here includes an insulating housing 30 and a shield shell 40 made of a metal material (FIGS. 1, FIG. 3, FIG. 5, FIG. 7, and FIG. 8).

The housing 30 is molded of an insulating material such as synthetic resin. At least the terminal fitting 10 is housed in the housing 30.

The housing 30 may be composed of one component, or may be configured as an assembly in which a plurality of components are assembled. The housing 30 shown here is composed of a first accommodating member 30A and a second accommodating member 30B (FIGS. 1, 3 and 8).

The first accommodating member 30A is formed into a tubular body having at least one end opened in the tubular axial direction, and the second accommodating member 30B is inserted into an inner space along the tubular axial direction from the opening. On the tubular outer peripheral wall 31 of the first accommodating member 30A, an insertion hole 32 for inserting the terminal fitting 10 into the inner space from the tip on the electrical connection portion 11 side is formed for each terminal fitting 10 (FIG. FIG. 8). Each terminal fitting 10 is inserted through the insertion hole 32 in the same direction. The first accommodating member 30A of this example accommodates the electrical connection portion 11 in the inner space, while the electric wire connecting portion 12 projects outward from the insertion hole 32.

The second accommodating member 30B has a terminal accommodating chamber 33 for accommodating the electrical connection portion 11 in the space inside the first accommodating member 30A for each terminal fitting 10 (FIG. 8). In the terminal accommodating chamber 33, as the second accommodating member 30B is inserted into the inner space of the first accommodating member 30A, the electrical connection portion 11 is accommodated in the inner space of the first accommodating member 30A. Begins to be accommodated through the opening 33a (FIG. 8). The electrical connection portion 11 is accommodated in the terminal accommodating chamber 33 by completing the accommodation of the second accommodating member 30B in the space inside the first accommodating member 30A. Since the second accommodating member 30B adopts such a form of accommodating the electrical connection portion 11 into the terminal accommodating chamber 33, the notch portion 34 is connected to the opening 33a on the outer peripheral surface side and communicates the terminal accommodating chamber 33 to the outside. (Fig. 8). The electric wire connecting portion 12 projects from the notch 34 to the outside of the second accommodating member 30B. The second accommodating member 30B is accommodated in the space inside the first accommodating member 30A so that the electric wire connecting portion 12 of the notch portion 34 projects outward from the insertion hole 32 of the first accommodating member 30A. It is arranged to face the insertion hole 32 in the state of being present. Further, in the second accommodating member 30B, the terminal accommodating chamber 33 has another opening on the side opposite to the opening 33a, and the other opening connects the electrical connection portion 511 of the mating terminal fitting 510 to the terminal accommodating chamber 33. It is used as a terminal insertion port 33b for accommodating in (FIG. 1). The electrical connection portion 511 is physically and electrically connected to the electrical connection portion 11 in the terminal accommodating chamber 33.

The first accommodating member 30A and the second accommodating member 30B are screwed and fixed to the shield shell 40 by using the male screw member B2 (FIGS. 3 and 8).

By accommodating at least the housing 30 inward, the shield shell 40 suppresses the intrusion of noise toward the electrical connection portion 11 of the terminal fitting 10 accommodated in the housing 30. The shield shell 40 shown here not only suppresses noise from entering the inside of the housing 30, but also noise toward the electric wire connecting portion 12 of the terminal fitting 10 and the terminal of the electric wire We drawn from the housing 30. It also suppresses the invasion of. Therefore, the shield shell 40 of this example accommodates the space between the housing 30 and the terminal of the electric wire We inward. The shield shell 40 includes a main shield body 41 that covers the housing 30 from the outside while exposing the terminal insertion port 33b, an electric wire connecting portion 12 that protrudes from the insertion hole 32 to the outside of the housing 30, and a terminal of the electric wire We. It has a sub-shield body 42 that covers the surface from the outside (FIGS. 1 to 8).

The main shield body 41 has a tubular shape with one end open in the tubular axis direction. In the main shield body 41, the housing 30 is housed inward through the opening, and the terminal insertion port 33b of the housing 30 is exposed from the opening.

The shield shell 40 has the fitting portion 21 shown above. In the shield shell 40, the peripheral edge of the opening of the main shield body 41 is used as the fitting portion 21.

In the shield shell 40, through holes to be arranged to face the insertion holes 32 of the housing 30 are formed on the outer peripheral wall of the main shield body 41 for each insertion hole 32, and the sub-shield body 42 that closes the through holes is a through hole. It is formed every time.

The sub-shield body 42 is formed in a tubular shape with both ends open. The sub-shield body 42 projects from the outer peripheral wall of the main shield body 41 so that its tubular axis direction faces orthogonal to the main shield body 41. In the shield shell 40, the spaces inside the main shield body 41 and the sub shield body 42 are communicated with each other through the through hole of the main shield body 41 and one opening of the sub shield body 42.

In the sub-shield body 42, the terminal of the electric wire We is pulled out from the other opening 42a (FIGS. 1, FIG. 2, FIG. 4, FIG. 6, and FIG. 8).

The sub-shield body 42 of this example is formed in a cylindrical shape, and an annular gap is formed between the inner peripheral surface thereof and the outer peripheral surface of the terminal of the electric wire We. An annular liquid-proof member Se2, which is a sealing member such as a rubber stopper and seals the annular gap thereof, is provided between the sub-shield body 42 and the terminal of the electric wire We (FIG. 8). The liquid-proof member Se2 is attached to the outer peripheral surface of the terminal of the electric wire We on the same axis as the terminal of the electric wire We.

A holding member 43 for pulling out the terminal of the electric wire We to the outside and closing the opening 42a is attached to the end of the sub-shield body 42 on the opening 42a side (FIGS. 1, FIG. 2, FIG. 4, FIG. 6). And FIG. 8). The holding member 43 is formed of a metal material. The holding member 43 of this example has a two-divided structure, suppresses misalignment of the liquid-proof member Se2, and keeps the electric wire We in the center of the sub-shield body 42.

By the way, in this connector 1, as shown above, the electric wire connecting portion 12 of the terminal fitting 10 is projected from the insertion hole 32 of the insulating housing 30, and the protruding electric wire connecting portion 12 is a conductive sub. It is covered with a shield body 42. Therefore, in this connector 1, an insulator is interposed between the conductive electric wire connecting portion 12 and the sub-shield body 42, and the insulating distance (space distance and creepage distance) between them is increased. The connector 1 includes an insulating tubular member (hereinafter, referred to as “insulated tubular”) 50 that covers the electric wire connecting portion 12 and the terminal of the electric wire We from the outside (FIG. 8). The insulating cylinder 50 is molded of an insulating material such as synthetic resin. The insulating cylinder 50 is inserted inside the sub-shield body 42, and one end side in the cylinder axis direction is inserted into the inside of the first accommodating member 30A from the insertion hole 32.

A screw structure in which a connector fitting force is generated between the connector 1 of the present embodiment and the mating connector 501 when fitting the connectors, and the connector 1 is fixed to the mating connector 501 side after the connector fitting is completed. Is provided. The screw structure utilizes the screw portion of the screw member B and the mating screw portion on the mating connector 501 side as shown above.

The screw member B is arranged to face the outer peripheral surface of the fitting portion 21 at intervals, and is rotatably held around the screw axis with respect to the housing 20. The screw member B utilizes the axial force exerted by its own screw portion on the mating screw portion 532 (FIGS. 2, FIG. 3, FIG. 5 and FIG. 7) of the connector fastening wall 531 to form a fitting portion. A connector fitting force in the tubular axis direction is generated between the 21 and the mating portion 523.

One of the screw portion and the mating screw portion 532 of the screw member B is formed as a female screw portion, and the other of them is formed as a male screw portion. For example, when the screw member B is a female screw member such as a nut, the male screw portion of the stud bolt as the mating screw portion 532 is projected from the connector fastening wall 531. In this example, the screw member B is formed as a male screw member such as a bolt. Therefore, a female screw portion as a mating screw portion 532 is formed on the connector fastening wall 531.

The screw member B is assembled to the shield shell 40. The screw member B of this example is arranged between the two sub-shield bodies 42 with the fitting connection direction of the fitting portion 21 with respect to the mating fitting portion 523 being the axial direction of the screw shaft. The shield shell 40 has a connecting body 44 that connects the two sub-shielding bodies 42 between the two sub-shielding bodies 42 (FIGS. 1 to 8). The connecting body 44 is arranged at intervals with respect to the outer peripheral surface of the main shield body 41. The connecting body 44 has a through hole 44a along the fitting connection direction of the fitting portion 21 with respect to the mating fitting portion 523 (FIGS. 1, FIG. 3, FIG. 5, FIG. 7, and FIG. 8). .. A screw member B is inserted through the through hole 44a. In the connecting body 44, the head of the screw member B is locked to one end of the through hole 44a in the hole axial direction, and the screw member is interposed at the other end of the through hole 44a in the hole axial direction via the locking member 45. By locking B, the screw member B is held in the through hole 44a in the inserted state (FIGS. 1, FIG. 3, FIG. 5, FIG. 7, and FIG. 8). In this example, a snap ring for a shaft is used for the locking member 45. In the following, when simply referred to as "fitting connection direction", the fitting connection direction means the fitting connection direction of the fitting portion 21 with respect to the mating portion 523.

In this connector 1, for example, when the fitting portion 21 and the mating mating portion 523 are started to be fitted, the screw portion of the screw member B and the mating screw portion 532 can be started to be screwed. The length of the screw portion of the screw member B is set. Here, the relative position between the screw portion of the screw member B and the mating screw portion 532 is referred to as a screwing start position. When the screw portion of the screw member B and the mating screw portion 532 are in the screwing start position, the fitting portion 21 does not cover the entire outer peripheral surface side of the liquid-proof member Se1, so that at least a part of the liquid-proof member Se1 is exposed. doing. Further, in this connector 1, when the fitting portion 21 and the mating fitting portion 523 are in the fitting completion position, the screw portion of the screw member B and the mating screw portion 532 are screwed together. Here, the relative position between the screw portion of the screw member B in the screwed completed state and the mating screw portion 532 is referred to as the screwed completed position.

The connector 1 of the present embodiment has a dustproof member 60 arranged between the outer peripheral surface of the fitting portion 21 and the screw member B so as to face the outer peripheral surface of the fitting portion 21 and the screw member B at intervals. (FIGS. 1 to 3, 5 to 8 and 10). Between the screw portion of the screw member B and the mating screw portion 532, there is a possibility that metal shavings may be generated when tightening or loosening these. The dustproof member 60 is arranged between the outer peripheral surface of the fitting portion 21 and the screw member B so that the metal shavings do not reach the liquidproof member Se1. The dustproof member 60 is molded of an insulating material such as synthetic resin.

The dustproof member 60 is held by the housing 20 so as to be movable relative to the housing 20 in the fitting connection direction and the opposite direction. Specifically, the dustproof member 60 is relatively moved with respect to the housing 20 in the fitting connection direction and vice versa, at least between the first dustproof position and the second dustproof position shown below. The first dustproof position is the relative position of the dustproof member 60 with respect to the housing 20 when the screw portion of the screw member B and the mating screw portion 532 are in the screwing start position. In the dustproof member 60 at the first dustproof position, the contact portion 61 is brought into contact with the connector fastening wall 531 in the fitting connection direction, and the screw member B side is covered from the outer peripheral surface side of the fitting portion 21 ( 5, FIG. 7 and FIG. 10). The second dustproof position is the relative position of the dustproof member 60 with respect to the housing 20 when the fitting portion 21 and the mating fitting portion 523 are in the fitting complete position. The dustproof member 60 at the second dustproof position is brought into contact with the connector fastening wall 531 in the fitting connection direction, and the screw member B side is covered from the outer peripheral surface side of the fitting portion 21.

The dustproof member 60 is formed so as to cover the screw portion of the screw member B and the portion of the mating screw portion 532 that protrudes from the connector fastening wall 531 from the outer peripheral surface side of the fitting portion 21. In this example, the screw member B is a male screw member, and the screw portion (male screw portion) of the screw member B is screwed into the mating screw portion 532 as the female screw portion of the connector fastening wall 531. Therefore, between the first dustproof position and the second dustproof position, the screw portion of the screw member B is projected from the connector fastening wall 531. Therefore, the dustproof member 60 fits the screw portion of the screw member B into the fitting portion 21. Cover from the outer peripheral surface side of. When the screw member B is a female screw member, the mating screw portion 532 as the male screw portion of the stud bolt is projected from the connector fastening wall 531. Therefore, the mating screw portion 532 is used as the screw portion of the screw member B ( The dustproof member 60 covers the fitting portion 21 from the outer peripheral surface side together with the female screw portion). The dustproof member 60 of this example is formed in a plate shape extending in the direction of relative movement with respect to the housing 20, and the flat surface of the dustproof member 60 covers the screw portion of the screw member B from the outer peripheral surface side of the fitting portion 21. In the dustproof member 60, one end portion in the relative moving direction is used as the contact portion 61.

The dustproof member 60 is assembled to the shield shell 40. In this example, the dustproof member 60 is assembled in the gap between the main shield body 41 and the connecting body 44.

In this connector 1, when the screw portion of the screw member B and the mating screw portion 532 are in the screwing start position, for example, an operator pushes the dustproof member 60 to move the contact portion 61 of the dustproof member 60. It is brought into contact with the connector fastening wall 531 (FIGS. 4 and 5). That is, in this connector 1, when the screw portion of the screw member B and the mating screw portion 532 reach the screwing start position, the dustproof member 60 is relatively moved to the first dustproof position with respect to the housing 20. In the connector 1, by tightening the screw member B in this state, the fitting amount of the fitting portion 21 and the mating portion 523 increases. Along with this, in the connector 1, the dustproof member 60 is in the direction opposite to the fitting connection direction with respect to the housing 20 while keeping the contact portion 61 in contact with the connector fastening wall 531 in the fitting connection direction. Retreat. In this connector 1, by further tightening the screw member B, the fitting amount of the fitting portion 21 and the mating portion 523 is further increased, and the contact portion 61 is brought into contact with the connector fastening wall 531 in the fitting connection direction. The dustproof member 60 further retracts with respect to the housing 20 in the direction opposite to the mating connection direction while being in contact with the housing 20. In this connector 1, when the fitting portion 21 and the mating fitting portion 523 reach the fitting completion position, the screw member B cannot be further tightened, and the fitting portion B is hit in the fitting connection direction. The position of the dustproof member 60 relative to the housing 20 is the second dustproof position while the contact portion 61 is in contact with the connector fastening wall 531 (FIGS. 6 and 7).

When the dustproof member 60 is relatively moved from the first dustproof position to the second dustproof position with respect to the housing 20, the contact portion 61 continues to contact the connector fastening wall 531 in the fitting connection direction. The screw member B is still covered from the outer peripheral surface side of the fitting portion 21. That is, the dustproof member 60 is attached to the housing 20 while the contact portion 61 is in contact with the connector fastening wall 531 in the fitting connection direction and the screw member B side is covered from the outer peripheral surface side of the fitting portion 21. On the other hand, it is held in the housing 20 so that it can be relatively moved from the first dustproof position to the second dustproof position. Therefore, when the connector 1 is fitted to the mating connector 501, metal shavings are generated between the screw portion of the screw member B and the mating screw portion 532, and the shavings serve as the female screw portion. Even if it pops out from the other screw portion 532, this shavings can be received by the dustproof member 60. Therefore, in this connector 1, the movement of metal shavings to the outer peripheral surface side of the fitting portion 21 and the liquid-proof member Se1 side can be suppressed by the dust-proof member 60, so that the fitting portion 21 and the mating portion 523 can be suppressed. It is possible to suppress the intrusion of metal shavings into the space between the two, and it is possible to suppress the adhesion of metal shavings to the liquid-proof member Se1. Along with this, in this connector 1, it is possible to suppress the adhesion of metal shavings to the terminal fitting 10 and the mating terminal fitting 510. Then, in this connector 1, the dragging of shavings between the fitting portion 21 and the liquid-proof member Se1 is suppressed, and the occurrence of scratches between the fitting portion 21 and the liquid-proof member Se1 can be suppressed. The liquidtightness between the fitting portion 21 and the mating portion 523 by the liquid-proof member Se1 can be improved. Further, in the connector 1, it is possible to prevent shavings from remaining between the fitting portion 21 and the liquid-proof member Se1 after the connector fitting is completed. Therefore, from this point as well, the liquid-proof member Se1 is used for fitting. The liquidtightness between the portion 21 and the mating portion 523 can be improved.

By the way, in this connector 1, there is a possibility that shavings generated when the connector is fitted to the mating connector 501 may remain around the screw portion of the screw member B even after the connector fitting is completed. Further, the connector 1 may be pulled out from the counterparty connector 501 when the connector is fitted to the counterparty connector 501. At that time, in the connector 1, the screw member B screwed to the mating screw portion 532 is loosened, and the screw member B is removed from the mating screw portion 532. Therefore, in this connector 1, metal shavings may be generated between the screw portion of the screw member B and the mating screw portion 532 even when the connector 1 is pulled out from the counterparty connector 501.

Therefore, this connector 1 suppresses the movement of shavings to the outer peripheral surface side of the fitting portion 21 when the connector is fitted to the mating connector 501, and until the pulling out is completed when the mating portion 21 is pulled out from the mating connector 501. It is configured to suppress the movement of shavings to the outer peripheral surface side of the fitting portion 21. For this purpose, the dustproof member 60 is arranged so as to face the locking portion 524 on the mating connector 501 side at the contact position of the contact portion 61 with respect to the connector fastening wall 531 on the mating connection direction side. A locked portion 62 that can be locked to the locking portion 524 is provided (FIGS. 3, 5, 7, and 10). The locked portion 62 of this example is a claw-shaped locking projection, which projects from one plane of the contact portion 61 of the dustproof member 60 toward the mating housing 520. Further, the locking portion 524 of this example is a locking projection for hooking the claw-shaped locked portion 62, and is projected from the mating housing 520. On the mating connector 501 side, a gap is formed between the locking portion 524 and the connector fastening wall 531. When the contact portion 61 is brought into contact with the connector fastening wall 531, the gap is covered. The locking portion 62 is inserted.

In this connector 1, when the connector is fitted to the mating connector 501, the dustproof member 60 is locked by the locked portion 62 and the locking portion 524 at the contact position of the contact portion 61 with respect to the connector fastening wall 531. Therefore, the dustproof member 60 is in a state of covering the screw member B from the outer peripheral surface side of the fitting portion 21 (FIGS. 6 and 7). Therefore, even if metal shavings remain around the screw portion of the screw member B when the connector is fitted to the mating connector 501, the connector 1 is fitted by receiving the shavings by the dustproof member 60. It is possible to suppress the movement of the joint portion 21 toward the outer peripheral surface side. Therefore, when the connector 1 is pulled out from the mating connector 501, it is possible to suppress the invasion of metal shavings between the mating portion 21 and the mating portion 523, and the connector 1 enters the liquid-proof member Se1. Adhesion of metal shavings can be suppressed. Further, in this connector 1, when the connector 1 is pulled out from the counterparty connector 501, the dustproof member 60 is locked by the locked portion 62 and the locking portion 524 at the contact position of the contact portion 61 with respect to the connector fastening wall 531. Therefore, the dustproof member 60 is in a state of covering the screw member B from the outer peripheral surface side of the fitting portion 21 (FIGS. 11 and 12). Therefore, when the connector 1 is pulled out from the mating connector 501, the dustproof member 60 catches and fits the metal shavings remaining after the connector fitting is completed and the metal shavings generated when the screw member B is loosened. It is possible to suppress the movement of the joint portion 21 to the outer peripheral surface side or the liquid-proof member Se1 side. Therefore, when the connector 1 is pulled out from the mating connector 501, it is possible to suppress the invasion of metal shavings between the mating portion 21 and the mating portion 523, and the connector 1 enters the liquid-proof member Se1. Adhesion of metal shavings can be suppressed. As described above, in this connector 1, even when the connector 1 is pulled out from the mating connector 501, it is possible to suppress the invasion of metal shavings between the mating portion 21 and the mating portion 523, and the liquid proof. Since it is possible to suppress the adhesion of metal shavings to the member Se1, the dragging of the shavings between the fitting portion 21 and the liquid-proof member Se1 is suppressed when the connector is fitted to the mating connector 501 again. In addition, it is possible to prevent shavings from remaining between the fitting portion 21 and the liquid-proof member Se1 after the connector fitting is completed. Therefore, from this point as well, the connector 1 can improve the liquidtightness between the fitting portion 21 by the liquid-proof member Se1 and the mating portion 523.

Here, the connector 1 is provided with an unlocking mechanism for releasing the locked state of the locked portion 62 with respect to the locking portion 524. The unlocking mechanism illustrated here utilizes the flexibility of the dustproof member 60. Therefore, the dustproof member 60 is provided with flexibility capable of bending in a direction orthogonal to the facing arrangement direction of the locked portion 62 and the locking portion 524 in the locked state. As shown above, the example dustproof member 60 is formed in a plate shape extending in the direction of relative movement with respect to the housing 20. Therefore, the dustproof member 60 may be formed to have a plate thickness capable of such bending. In this dustproof member 60, as shown above, since the locked portion 62 is provided in the contact portion 61, the locked portion 62 is engaged with the contact portion 61 by bending itself. It can be pulled out from the gap between the stop portion 524 and the connector fastening wall 531. For example, in this connector 1, in a state where the screw member B is removed from the mating screw portion 532 and the fitting portion 21 is removed from the mating fitting portion 523 (FIGS. 13 and 14), the mating connector 501 is connected. On the other hand, by being shaken, the dustproof member 60 is bent so that the locked portion 62 is pulled out from the gap between the locking portion 524 and the connector fastening wall 531.

The connector 1 is provided with a detection mechanism for detecting a state in which the screw member B is removed from the mating screw portion 532 and the fitting portion 21 is removed from the mating fitting portion 523. The detection mechanism includes the dustproof member 60 when the screw member B is removed from the mating screw portion 532 and the fitting portion 21 is removed from the mating fitting portion 523, or after the state is reached. The housing 20 is brought into contact with the housing 20 from the mating connection direction side to detect the housing 20. Therefore, the dustproof member 60 is provided with the abutted portion 63 that is brought into contact with the abutting portion 46 of the housing 20 from the mating connection direction side when or after the state is reached ( 3, FIG. 5, FIG. 7, FIG. 12 and FIG. 14). The contacted portion 63 of this example is arranged at an end portion of the dustproof member 60 opposite to that of the contacted portion 61, and projects from one plane in the same direction as the locked portion 62.

It is used as part 46.

As shown above, in the connector 1 of the present embodiment, the dustproof member 60 fits between the first dustproof position and the second dustproof position with the contact portion 61 in contact with the connector fastening wall 531. Since the screw member B side is covered from the outer peripheral surface side of the portion 21, it is possible to suppress the intrusion of metal shavings between the fitting portion 21 and the mating portion 523, and the liquid-proof member Se1. Adhesion of metal shavings to the surface can be suppressed. Along with this, in the connector 1 of the present embodiment, it is possible to suppress the adhesion of metal shavings to the terminal fitting 10 and the mating terminal fitting 510, and the fitting portion 21 and the mating portion are fitted by the liquid-proof member Se1.
