  Specifically, the illustrated held portion 13 is formed in a T-shape that protrudes along the virtual axis P from the tip (one end portion 11 c) of the electrical connection portion 11. The held portion 13 includes a T-shaped first wall surface 13 a (FIGS. 6, 8, and 9) disposed on the same plane as the first wall surface 11 a of the electric connection portion 11, and the first portion of the electric connection portion 11. The second wall surface 11b has a T-shaped second wall surface 13b (FIGS. 7 and 9) disposed on the same plane. The held portion 13 includes a T-shaped shaft portion 13c having a central axis disposed on the virtual axis P, and an intersecting portion 13d orthogonal to the shaft portion 13c at the tip of the shaft portion 13c. (FIGS. 6 to 9). The held portion 13 uses a notch-shaped groove portion 13e (FIGS. 4 and 6 to 9) formed between the one end portion 11c of the electrical connecting portion 11 as an inserted portion. is there. The groove 13e is formed at two places with the virtual axis P as the center.

  The illustrated held portion 13 is configured so that both the shapes around the virtual axis P are the same in a direction orthogonal to the axial direction and a direction orthogonal to the first and second wall surfaces 13a and 13b. Is formed. Therefore, the held portion 13 can use both groove portions 13e as inserted portions. For example, in the terminal fitting 10, when the first end surface 11 e is disposed opposite to the terminal insertion port 43 in the terminal accommodating chamber 41, one of the two groove portions 13 e is used as the inserted portion. Further, in the terminal fitting 10, when the second end surface 11 f is disposed opposite to the terminal insertion port 43 in the terminal accommodating chamber 41, the other of the two groove portions 13 e is used as the inserted portion.

The terminal holding part 46 is inserted into the groove part 13e of the held part 13 in a state where the second accommodating member 40 is accommodated in the accommodating space 33. In this example, the wall portion 41b forming the terminal receiving chamber 41, to form a notch-shaped groove 41b ₁ which notched along the tube axis direction of the outer peripheral wall 31 (FIG. 11). In this illustrated terminal holding portion 46, the remaining portion of the wall portion 41 b whose apex is the bottom side of the groove portion 41 b ₁ is used as an insertion portion to the held portion 13. In the illustrated held portion 13 and terminal holding portion 46, the fitting between the groove portions 13 e and 41 b ₁ starts as the second accommodation member 40 is inserted into the accommodation space 33. And in this to-be-held part 13 and the terminal holding | maintenance part 46, the insertion to the groove part 13e of the remaining part of the wall part 41b is completed with the completion of accommodation to the accommodation space 33 of the 2nd accommodating member 40, and a terminal accommodation chamber In 41, the electrical connection portion 11 can be held in the accommodated state.

  Here, in the held portion 13, when the remaining portion of the wall portion 41b is inserted into the groove portion 13e, the intersecting portion 13d is disposed outward from the outer peripheral surface of the second housing member 40 (FIG. 3 and FIG. 4). Therefore, in the container 20A, an annular gap 21 is provided between the inner peripheral surface of the first storage member 30 and the outer peripheral surface of the second storage member 40 (FIGS. 3 and 4). The interval of the gap 21 is set to such a size that fingers of an operator or the like cannot enter while the intersection 13d can be arranged. In this connector 1, the continuity check can be performed using the intersection 13 d arranged in the gap 21.

By the way, in the guide part 35 shown previously, shakiness of the electrical connection part 11 can be suppressed between each protrusion part 35a. The electrical connecting portion 11 is arranged so that _one of the first end surface 11e and the second end surface 11f faces the groove bottom 35b1 of the guide groove 35b in a state where the second housing member 40 is housed in the housing space 33. The other of them is opposed to the end face 45a of the contact prevention portion 45 (the end face opposite to the terminal insertion port 43 side) (FIG. 4). Thus, the first housing member 30 and the second housing member 40 in a state where housing between each other has been completed, formed so as to sandwich the electrical connecting portion 11 between the groove bottom 35b ₁ and the end face 45a Also good. That is, you may form the 1st accommodating member 30 and the 2nd accommodating member 40 so that the electrical connection part 11 may be inserted | pinched and hold | maintained in the state which the accommodation between each other has completed. As a result, the connector 1 can enhance the effect of preventing the electrical connection portion 11 from coming off in the terminal accommodating chamber 41 by the terminal holding portion 46 and suppress the rattling of the electrical connecting portion 11 in the terminal accommodating chamber 41. be able to. Therefore, this connector 1 can improve vibration resistance and can improve fitting workability with the mating connector 101. In the illustrated connector 1, the first housing member 30 and the second housing member 40 are fastened together with the shield shell 20 </ b> B by an axial force in the cylinder axis direction, as will be described later, in order to obtain such an effect.

(FIG. 4).

The outer peripheral wall 51a has a through hole 51a ₁ of the first housing member 30 is opposed to the insertion hole 34 in a state of being accommodated in the accommodating space 51c (Fig. 14). The through hole 51a ₁ is provided for each terminal fitting 10. In this illustration, the through-holes 51a ₁ is provided with two.

The sub shield body 52 is provided for each terminal fitting 10. Accordingly, here, two sub shield bodies 52 are provided. The sub shield body 52 is formed in a cylindrical shape having both ends opened. The illustrated secondary shield body 52 is formed in a cylindrical shape. In the shield shell 20 </ b> B, the sub shield body 52 protrudes outward from the main shield body 51 from the peripheral edge of the through hole 51 a ₁ of the main shield body 51. The illustrated auxiliary shield body 52 is projected so that the cylinder axis direction is along the terminal insertion direction. In the sub shield body 52, the terminal fitting 10 is inserted into the inner accommodation space 52b from the opening 52a on the free end side (FIG. 5). The terminal fitting 10 is inserted into the accommodation space 33 from the front end through the through hole 51 a ₁ of the main shield body 51 and the insertion hole 34 of the first accommodation member 30.

  The shield shell 20B has a connecting body 53 that connects two adjacent sub shield bodies 52 arranged in parallel (FIGS. 2 to 5 and FIG. 13). The connecting body 53 only needs to connect at least two adjacent sub shield bodies 52 arranged in parallel, and may connect all the sub shield bodies 52 (for example, three sub shield bodies 52). Good. The illustrated coupling body 53 is interposed between two adjacent sub shield bodies 52 arranged in parallel. The connector 53 is screwed and fixed in a connector-fitted state to a wall surface 201a (FIG. 1) of a conductive installation object of the mating connector 101 (in this example, a casing 201 made of a conductive material such as metal). By doing so, the connector 1 is fixed to the counterpart connector 101 side. Therefore, this connection body 53 has the through-hole 54 utilized for the screwing fixation (FIG. 3). The through hole 54 will be described in detail later.

  Here, an annular seal member Se2 is concentrically attached to the end of the electric wire We (FIGS. 4 and 5). The sealing member Se2 is in close contact with the inner peripheral surface of the sub shield body 52 in a state where the electrical connection portion 11 is housed in the housing space 33, and improves the liquid tightness between the sub shield body 52 and the electric wire We ( FIG. 4).

  The holding member 20 </ b> C has a cylindrical outer peripheral wall (an outer peripheral wall 62, which will be described later) into which the end of the sub shield body 52 on the opening 52 a side is fitted, and is arranged in the accommodation space 52 b of the sub shield body 52. It is the cylindrical member formed so that the electric wire We could be pulled out outward. The holding member 20C is formed of a conductive material such as metal. This holding member 20 </ b> C is provided for each terminal fitting 10. In this example, two holding members 20C are provided.

  This exemplary holding member 20C has a cylindrical inner peripheral wall 61 and a cylindrical outer peripheral wall 62 that are concentrically arranged at an interval in the radial direction (FIGS. 13 and 14). The inner peripheral wall 61 and the outer peripheral wall 62 each have both ends opened in the cylinder axis direction. Therefore, a cylindrical gap 63 is formed in the holding member 20C between the inner peripheral wall 61 and the outer peripheral wall 62 (FIG. 14). In the illustrated holding member 20C, an annular opening at one end in the cylinder axis direction of the cylindrical gap 63 is closed with an annular wall (hereinafter referred to as “annular wall”) 64 (FIG. 13). The holding member 20C inserts and fits the end portion on the opening 52a side of the sub shield body 52 from the opening 63a (FIG. 14) at the other end in the cylindrical axis direction into the cylindrical gap 63. Therefore, in this holding member 20C, the inner peripheral wall 61 is inserted into the accommodating space 52b of the sub shield body 52, and the outer peripheral wall 62 covers the outer peripheral surface of the outer peripheral wall 52c of the sub shield body 52 (FIGS. 13 to 15). In the holding member 20 </ b> C, the electric wire We routed in the accommodation space 52 b of the sub shield body 52 is guided to the inner space of the inner peripheral wall 61, and is drawn outward from the opening at one end of the inner peripheral wall 61. It is.

  The sub shield body 52 and the holding member 20 </ b> C hold the fitted state of each other by the lock mechanism L (FIGS. 13 and 14). In this example, the lock mechanisms L are provided at two locations. The lock mechanism L includes a first engagement body 55 provided on the sub shield body 52 and a second engagement body 65 provided on the holding member 20C.

  The first engagement body 55 is protruded radially outward from the outer peripheral wall 52c at the end of the sub shield body 52 on the opening 52a side. The illustrated first engaging body 55 is formed in a claw shape capable of hooking the second engaging body 65.

  On the other hand, the second engaging body 65 is provided at a location where a part of the outer peripheral wall 62 of the holding member 20C is removed in the circumferential direction. The illustrated second engagement body 65 has a base portion 65a that is flush with the annular wall 64 and protrudes radially outward from the outer peripheral surface of the inner peripheral wall 61 (FIGS. 13 and 14). Further, the illustrated second engagement body 65 has first and second flexible shaft portions 65b and 65c having flexibility at both ends in the circumferential direction of the base portion 65a (FIGS. 13 and 14). The first and second flexible shaft portions 65b and 65c are respectively protruded from both ends in the circumferential direction of the base portion 65a toward the opening 63a in the cylindrical axis direction of the holding member 20C. Further, the first and second flexible shaft portions 65b and 65c are arranged at the same position as the outer peripheral wall 62 in the radial direction of the holding member 20C. Furthermore, the illustrated second engaging body 65 has an engaging portion 65d that connects the protruding end portions of the first and second flexible shaft portions 65b and 65c (FIGS. 13 and 14). The second engaging body 65 can move the engaging portion 65d in the radial direction with respect to the inner peripheral wall 61 by bending the first and second flexible shaft portions 65b and 65c.

  In this locking mechanism L, the engaging portion 65d is bent into the first engaging body 55 while the second engaging body 65 is bent by starting to insert and fit the holding member 20C into the end portion on the opening 52a side of the sub shield body 52. Get on. In the lock mechanism L, when the fitting between the sub shield body 52 and the holding member 20C is completed, the engagement portion 65d of the second engagement body 65 gets over the first engagement body 55, and the second engagement The bending of the combined body 65 is eliminated. Thereby, in this lock mechanism L, the first engaging body 55 and the engaging portion 65d of the second engaging body 65 are arranged in the cylinder axis direction of the outer peripheral wall 62 so that the holding member 20C does not come off from the sub shield body 52. It becomes a lockable state.

  Here, the sub shield body 52 includes a locking body on the outer peripheral wall 52c at the end on the opening 52a side. The engaging body is a projecting body projecting from the outer peripheral wall 52c at the end of the sub shield body 52 on the opening 52a side, and a plurality of the engaging bodies are preferably provided on the outer peripheral wall 52c. In addition, the holding member 20 </ b> C includes a clearance in the outer peripheral wall 62 in which the engaging body is inserted. In the lock mechanism L, the holding member 20C is fitted to the end portion on the opening 52a side of the sub shield body 52, and the engagement between the first engagement body 55 and the second engagement body 65 is completed. The locking body is inserted into the gap. Here, two locking bodies (first and second locking bodies 56A and 56B) are provided in the sub shield body 52, and two gaps (first and second gaps 66A and 66B) are provided as holding members. 20C (FIGS. 13 and 14). In the lock mechanism L, the holding member 20C is fitted to the end portion on the opening 52a side of the sub shield body 52, and the engagement between the first engagement body 55 and the second engagement body 65 is completed. The first locking body 56A is inserted into the first gap 66A, and the second locking body 56B is inserted into the second gap 66B.

  Specifically, the illustrated first and second locking bodies 56A and 56B are protruded radially outward from the outer peripheral wall 52c at the end of the sub shield body 52 on the opening 52a side, and The auxiliary shield body 52 extends in the cylinder axis direction. Here, the first and second locking bodies 56A and 56B are formed in a rectangular shape. Further, the illustrated first and second locking bodies 56A, 56B are the first engaging body 55 in the circumferential direction of the sub shield body 52 at the outer peripheral wall 52c at the end of the sub shield body 52 on the opening 52a side. Are formed so as to interpose them. On the other hand, the outer peripheral wall 62 is provided with the first and second gaps 66A and 66B, thereby forming one end 62a forming one wall surface in the first gap 66A and one wall surface in the second gap 66B. The other end 62b is formed (FIGS. 13 and 14). The illustrated first gap 66A is provided between the one end 62a and the first flexible shaft 65b in the circumferential direction of the outer peripheral wall 62 (FIGS. 13 and 14). The illustrated second gap 66B is provided between the other end 62b and the second flexible shaft 65c in the circumferential direction of the outer peripheral wall 62 (FIGS. 13 and 14).

  The first locking body 56A and the first gap 66A are arranged such that when the first locking body 56A is inserted into the first gap 66A, one end portion 62a of the outer peripheral wall 62 and the first flexible shaft portion 65b Between these, one end and the other end in the circumferential direction of the first locking body 56A are formed and arranged so as to face each other in the circumferential direction. The first locking body 56A and the first gap 66A are formed and arranged so as to suppress the relative rotation in the circumferential direction between the sub shield body 52 and the holding member 20C. For example, the first locking body 56A and the first gap 66A are defined by the circumferential distance between one end of the first locking body 56A in the circumferential direction and the one end 62a of the outer peripheral wall 62, and the first locking body 56A. The circumferential distance between the other end in the circumferential direction of the first flexible shaft portion 65b and the first flexible shaft portion 65b is as narrow as possible within a range that allows the first locking body 56A to be inserted into the first gap 66A. Formed and arranged. As a result, the first locking body 56A is attached to one end 62a of the outer peripheral wall 62 or the first flexible shaft portion 65b when the sub shield body 52 and the holding member 20C try to rotate relative to each other in the circumferential direction. It is locked in the circumferential direction. Therefore, the first locking body 56A and the first gap 66A can suppress relative rotation of the auxiliary shield body 52 and the holding member 20C in the circumferential direction.

  Similarly, the second locking body 56B and the second gap 66B are connected to the second end 62b of the outer peripheral wall 62 and the second allowable portion when the second locking body 56B is inserted into the second gap 66B. It forms and arrange | positions so that the one end and other end in the circumferential direction of the 2nd latching body 56B may each be opposingly arranged by the circumferential direction between the flexible shaft parts 65c. And the 2nd latching body 56B and the 2nd clearance gap 66B are formed and arrange | positioned so that the relative rotation of the circumferential direction between the subshield body 52 and the holding member 20C can be suppressed. For example, the second locking body 56B and the second gap 66B are formed in the circumferential direction between the one end in the circumferential direction of the second locking body 56B and the other end 62b of the outer peripheral wall 62 and the second locking body 56B. The circumferential distance between the other end in the circumferential direction of the second flexible shaft portion 65c and the second flexible shaft portion 65c is so narrow as to be as narrow as possible within a range that allows the second locking body 56B to be inserted into the second gap 66B. Formed and arranged. As a result, when the sub-shield body 52 and the holding member 20C are about to rotate relative to each other in the circumferential direction, the second locking body 56B is placed on the other end portion 62b of the outer peripheral wall 62 or the second flexible shaft portion 65c. It is locked in the circumferential direction. Therefore, the second locking body 56B and the second gap 66B can suppress relative rotation of the auxiliary shield body 52 and the holding member 20C in the circumferential direction.

  The connector 1 includes a second shield member 71 that is electrically connected to the shield shell 20B in addition to the shield shell 20B as the first shield member (FIGS. 1 to 5 and FIG. 15). The second shield member 71 covers the electric wire We drawn from the opening 52a together with the end of the sub shield body 52 on the opening 52a side, thereby suppressing the intrusion of noise from the outside to the electric wire We. . The second shield member 71 is formed in a cylindrical shape and is provided for each terminal fitting 10. Here, two second shield members 71 are provided. In the connector 1, the electric wire We is drawn outward from the holding member 20 </ b> C attached to the opening 52 a of the sub shield body 52. Therefore, the illustrated second shield member 71 is formed so as to cover the end on the opening 52a side of the sub shield body 52, the holding member 20C, and the electric wire We drawn from the holding member 20C from the outside. . Thereby, this 2nd shield member 71 can suppress the penetration | invasion of the noise from the outside with respect to the electric wire We pulled out from 20 C of holding members. Specifically, the illustrated second shield member 71 is provided as a braid in which conductive strands are knitted into a cylindrical shape and a mesh shape. Therefore, the second shield member 71 of this example has flexibility, and can follow movements such as bending of the inner electric wire We. In the drawing, for convenience of illustration, the specific shape (such as a mesh) of the second shield member 71 is omitted.

  The second shield member 71 is fixed to the sub shield body 52 with a binding member (binding band 75) made of a conductive material such as metal (FIGS. 4, 5, and 15). As the binding band 75, one known in this technical field is used. For example, the binding band 75 is wound around the second shield member 71 and the end portion on the opening 52 a side of the sub shield body 52 from above the second shield member 71. The binding band 75 forms an annular shape by being tightened, and fixes the second shield member 71 to the end of the sub shield body 52 on the opening 52a side.

  Here, the binding band 75 is a secondary shield with respect to the end surface 62c on the opening 63a side and the end surface 56a on the main shield body 51 side of the first and second locking bodies 56A and 56B in the outer peripheral wall 62 of the holding member 20C. Winding is performed at a position facing the body 52 in the cylinder axis direction (FIG. 15). As a result, the binding band 75 that forms an annular shape (here, an annular shape) after winding is formed on the cylindrical surface between the end surface 62c of the outer peripheral wall 62 and the end surfaces 56a of the first and second locking bodies 56A and 56B. It will be arranged opposite to the direction. In this example, the end surfaces 56a of the first and second locking bodies 56A and 56B are projected in the cylinder axis direction with respect to the end surface 62c of the outer peripheral wall 62. Thereby, the end surfaces 56a of the first and second locking bodies 56A and 56B can be used as a locking portion that can lock the tightened binding band 75 in the cylinder axis direction. For example, in this connector 1, when a pulling force is generated in the direction in which the second shield member 71 is pulled out from the sub shield body 52, the binding band 75 together with the second shield member 71 is attached to the sub shield body 52. Even if they are relatively moved in the cylinder axis direction, the binding band 75 is locked by the end surfaces 56a of the first and second locking bodies 56A, 56B. Therefore, in the connector 1, the second shield member 71 can be held while being fastened to the sub shield body 52. Therefore, the connector 1 can keep the physical and electrical connection state between the sub shield body 52 and the second shield member 71, so that it is possible to suppress a decrease in shield performance. Thus, in this connector 1, the first and second locking bodies 56 </ b> A and 56 </ b> B have a function of holding the second shield member 71 with respect to the sub-shield body 52, and are compatible with the sub-shield body 52 described above. The holding member 20C has a function of inhibiting relative rotation. Therefore, this connector 1 can suppress the enlargement of a physique compared with what established each function in the separate site | part.

  Further, in this connector 1, the sub shield body 52 of the shield shell 20 </ b> B is provided for each terminal fitting 10, and the second shield member 71 is connected to each sub shield body 52, whereby each electric wire We is individually connected. Covered with a second shield member 71. Therefore, since this connector 1 can pull out each electric wire We from the subshield body 52 with flexibility compared with what covers each electric wire We bundled together with one braid, The degree of freedom of the routing route of each electric wire We can be increased. Moreover, since this connector 1 does not need to bundle each electric wire We together, generation | occurrence | production of the thermal interference between each electric wire We can be suppressed. Therefore, in this connector 1, since the diameter increase of each electric wire We can be suppressed, the freedom degree of the routing route of each electric wire We can further be raised.

  By the way, in this connector 1, as shown previously, the electric wire connection part 12 of the terminal metal fitting 10 is protruded from the insulating container 20A, and the protruding electric wire connection part 12 is connected to the conductive sub-shield body 52. Covered with. Therefore, in this connector 1, an insulator is interposed between the conductive wire connecting portion 12 and the sub shield body 52, and the insulation distance (spatial distance) therebetween is increased. The connector 1 includes an insulating cylinder member (hereinafter referred to as an “insulating cylinder”) 80 that covers the wire connection portion 12 and the end of the wire We from the outside (FIGS. 3 to 5, 16, and 17). ).

  The insulating cylinder 80 is formed of an insulating material such as synthetic resin. The illustrated insulating cylinder 80 includes a rectangular tube-shaped cylinder 81 that accommodates the wire connection portion 12 and the end of the wire We inward (FIGS. 4, 5, 16, and 17). One end side of the cylinder 81 in the cylinder axis direction is inserted into the accommodation space 33 of the first accommodation member 30 while the electric wire connection portion 12 is accommodated inward. Therefore, the terminal fitting 10 is inserted into the accommodation space 33 through the insertion hole 34 from the tip on the electric connection portion 11 side together with one end portion of the insulating tube 80 in the direction of its own cylinder axis. Therefore, in this connector 1, it is desirable that the insertion hole 34 of the first housing member 30 is formed in a substantially rectangular shape, and the cylindrical body 81 is formed so that it can be fitted into the insertion hole 34. In the accommodating body 20 </ b> A, the second accommodating member 40 is inserted into the accommodating space 33 in a state where one end of the insulating cylinder 80 and the electrical connection portion 11 are accommodated in the accommodating space 33.

  The illustrated insulating cylinder 80 has a locking claw 82 at one end in the direction of its own cylinder axis (FIGS. 3, 5, 16 and 17). In this illustration, the locking claw 82 is provided in at least one place on one end side of the cylinder 81 in the cylinder axis direction. The locking claw 82 is formed as a protruding body on the outer peripheral wall on one end side of the cylinder 81 and is accommodated in the accommodation space 33. This locking claw 82 can be locked to the peripheral edge portion of the insertion hole 34 in the outer peripheral wall 31 of the first storage member 30 in the cylindrical axis direction of the cylindrical body 81 whose one end side is stored in the storage space 33 (see FIG. 3 and FIG. 17). Therefore, the latching claw 82 can temporarily hold the insulating cylinder 80 in the first housing member 30 until the second housing member 40 is housed in the housing space 33.

  Further, in this connector 1, a locked portion 83 (FIGS. 3, 5, 16, and 17) provided on the insulating cylinder 80 and a locking portion 47 (FIG. 10, FIG. 10) provided on the second housing member 40 are provided. 11 and 17), the movement of the insulating cylinder 80 relative to the container 20A in the direction of its own cylinder axis is locked. The locked portion 83 and the locking portion 47 may have any shape as long as such locking is possible. For example, one of the locked portion 83 and the locking portion 47 is formed in a protrusion shape, and the other is formed in a groove shape into which the other party is inserted. The illustrated insulating cylinder 80 has a locked portion 83 at one end in its cylinder axis direction. In this example, the locked portion 83 is provided on one end side of the cylinder 81 in the cylinder axis direction. The locked portion 83 is provided as a single piece projecting from one end of the cylinder 81 in the cylinder axis direction. The illustrated locked portion 83 includes a first piece 83 a that protrudes from one end of the cylinder 81 in the cylinder axis direction, and a second piece 83 b that is disposed orthogonal to the first piece 83 a. It is formed in a letter shape (FIGS. 16 and 17). One end of the insulating cylinder 80 is inserted into the accommodation space 33 from the insertion hole 34 so that the direction orthogonal to the L-shaped cross section of the locked portion 83 faces the cylinder axis direction of the first accommodation member 30. . The second housing member 40 is provided with a groove-like locking portion 47 that houses the second piece 83 b in the housing space 33. The engaging portion 47 is a groove for each insulating cylinder 80 extending along the cylinder axis direction of the first housing member 30, and the second piece portion is inserted into the housing space 33 of the second housing member 40. 83 b is inserted along the cylinder axis direction of the first housing member 30. The second piece 83b can be locked by the two side walls of the locking portion 47 (walls facing each other along the cylinder axis direction of the cylinder 81). Therefore, in this connector 1, the position shift along the cylinder axis direction of the insulating cylinder 80 with respect to the container 20A and the shield shell 20B can be suppressed.

  In this connector 1, the second shield member 71 is covered with an exterior member CB from the outside (FIGS. 1 to 5). The exterior member CB is, for example, a corrugated tube or a boot, and is formed of an insulating material such as a synthetic resin. The illustrated exterior member CB is formed to be bendable in order to increase the degree of freedom of the wiring route of the electric wire We. For example, the exterior member CB is provided with bendable cylinder portions CBa and CBb for each electric wire We drawn from the holding member 20C (FIGS. 1 to 3). The exterior member CB is fixed to the shield shell 20B with, for example, a binding band CB0.

  In the connector 1, the first housing member 30 is housed in the housing space 51 c of the main shield body 51, and the terminal fitting 10 attached to the terminal of the electric wire We and inserted into the insulating cylinder 80 is first housed from the tip. It is accommodated in the accommodating space 33 of the member 30. In this connector 1, the second housing member 40 is inserted into the housing space 33 in this state. In the connector 1, the first housing member 30, the second housing member 40, and the shield shell 20 </ b> B are screwed and fixed to keep these components in a fixed state. For example, in the illustrated main shield body 51, a female screw portion N whose axis is the direction of its own cylinder axis is formed (FIGS. 12 and 14). The first housing member 30, the second housing member 40, and the shield shell 20B are fixed by screwing the male screw member B (FIG. 5) into the female screw portion N. A through hole 37 through which a cylindrical boss 51d (FIGS. 12 and 14) having a female screw portion N is inserted is formed in the first housing member 30 (FIGS. 3, 5, and 12). Further, the second housing member 40 is formed with a through hole 48 through which the male screw member B is inserted (FIGS. 3, 5, 11, and 12). The through-holes 37 and 48 have the cylinder axis direction of the outer peripheral wall 31 as an axis. The boss portion 51d has the cylinder axis direction of the outer peripheral wall 51a as the axis. Therefore, the 1st accommodating member 30, the 2nd accommodating member 40, and the shield shell 20B are fastened together with the axial force of a cylinder axial direction.

  As described above, the connector 1 described above is inserted and fitted into the counterpart connector 101 and is electrically connected to the counterpart connector 101. Therefore, the counterpart connector 101 will be described below.

  The mating connector 101 includes a mating terminal 110 that is electrically connected to the terminal fitting 10 (FIGS. 18 and 19). The counterpart terminal 110 is provided for each terminal fitting 10. The illustrated mating connector 101 includes two mating terminals 110.

  The counterpart terminal 110 may use itself as a contact portion. In this case, the terminal fitting (hereinafter referred to as “mating terminal fitting”) 120 itself becomes the mating terminal 110. On the other hand, the counterpart terminal 110 may be a counterpart terminal member 120 attached to the contact member 130.

  The mating terminal fitting 120 is formed into a female mold using a conductive material such as metal (copper, copper alloy, aluminum, aluminum alloy, etc.). In this example, a conductive metal plate is used as a base material, and a female mating terminal fitting 120 is formed by pressing such as cutting or bending.

  The mating terminal fitting 120 includes a first electrical connection portion 121 and a second electrical connection portion 122 that are arranged to face each other with a space therebetween (FIGS. 20 and 21). The first electrical connection part 121 and the second electrical connection part 122 are each formed in a flat plate shape having two flat wall surfaces. In this example, the first electrical connection portion 121 and the second electrical connection portion 122 are each formed in a substantially rectangular flat plate shape. In addition, the illustrated first electrical connection portion 121 and second electrical connection portion 122 are each formed in an equivalent shape. In the mating terminal fitting 120, one of the two wall surfaces of the first electrical connection portion 121 and the second electrical connection portion 122 (hereinafter referred to as “opposing wall surface”) 121 a and 122 a is spaced from each other. Are arranged opposite to each other (FIGS. 20 and 21). The opposing wall surfaces 121a and 122a are arranged to face each other with an interval so as to be parallel to each other.

  In the mating terminal fitting 120, the electrical connection portion 11 is inserted between the first end portions 121b and 122b (FIGS. 20 and 21) of the first electrical connection portion 121 and the second electrical connection portion 122, and then inserted. The electrical connection part 11 is electrically connected. The first electrical connection portion 121 and the second electrical connection portion 122 are arranged on one of the opposing wall surfaces 121a and 122a of the respective one end portions 121b and 122b, and are located within the first wall surface 11a and the second wall surface 11b of the electrical connection portion 11. It is formed and arranged so that one of them is opposed and the other of the first wall surface 11a and the second wall surface 11b is opposed to the other of the opposite wall surfaces 121a and 122a. In other words, the first electrical connection portion 121 and the second electrical connection portion 122 are formed and arranged so that the first wall surface 11a and the second wall surface 11b may be disposed to face each of the opposing wall surfaces 121a and 122a. . In this illustration, the opposing wall surfaces 121a and 122a and the first and second wall surfaces 11a and 11b are arranged to face each other in a parallel state.

  When the counterpart terminal fitting 120 is used as a contact point with the electrical connection part 11, the first electrical connection part 121 and the second electrical connection part 122 are provided with contact parts (not shown). In this case, the 1st electrical connection part 121 provides the bulging part bulged toward the opposing wall surface 122a of the 2nd electrical connection part 122 from the opposing wall surface 121a of the one end part 121b as a contact part. And the 2nd electrical connection part 122 provides the bulging part bulged from the opposing wall surface 122a of the one end part 122b toward the opposing wall surface 121a of the 1st electrical connection part 121 as a contact part. Each contact portion has, for example, a spherical surface serving as a contact, and is arranged to face each other with a space in the direction orthogonal to the respective opposing wall surfaces 121a and 122a. The interval between the contact portions is made narrower than the plate thickness of the electrical connection portion 11. Therefore, the 1st electrical connection part 121 and the 2nd electrical connection part 122 insert each electrical connection part 11 between them, and each contact part is made into the 1st wall surface 11a of the electrical connection part 11, and the 2nd wall surface 11b. Can be contacted. Therefore, the first electrical connection part 121 and the second electrical connection part 122 are physically and electrically connected to the electrical connection part 11 in the terminal accommodation chamber 41 of the second accommodation member 40 of the housing 20. Is done.

  In the mating terminal fitting 120, the first electrical connecting portion 121 and the second electrical connecting portion 122 are connected by a connecting portion 123 (FIGS. 20 and 21). The connecting portion 123 connects one side end portions of the other end portions 121c and 122c of the first and second electrical connecting portions 121 and 122, respectively.

  Further, the mating terminal fitting 120 has a fixed portion 124 that is fixed to a casing 140 described later (FIGS. 20 and 21). The fixed portion 124 is provided on one of the first electrical connection portion 121 and the second electrical connection portion 122. The illustrated fixed portion 124 is formed in a single body shape and protrudes from an end portion in the connector insertion / extraction direction of the other end portion 122 c of the second electrical connection portion 122. Here, the to-be-fixed part 124 is protruded toward the orthogonal direction with respect to the opposing wall surface 122a of the 2nd electrical connection part 122. As shown in FIG. The fixed portion 124 is formed with a through hole 124a through which a male screw member B1 described later is inserted.

  On the other hand, when the contact member 130 is provided, the contact member 130 is attached to the first electrical connection portion 121 and the second electrical connection portion 122, respectively. In this embodiment, this case is given as an example.

  As the contact member 130, different members may be used for the first electrical connection portion 121 and the second electrical connection portion 122, and the same contact member 130 may be used for the first electrical connection portion 121 and the second electrical connection portion 122. May be. Here, the contact member 130 is shared by the first electrical connection part 121 and the second electrical connection part 122.

  The contact member 130 is physically attached to the first electrical connection portion 121 and the second electrical connection portion 122 by being attached to the respective one end portions 121 b and 122 b of the first electrical connection portion 121 and the second electrical connection portion 122. Connected electrically and electrically. That is, the counterpart terminal 110 includes a pair of the first electrical connection portion 121 and one contact member 130 that are in contact with each other, and a pair of second electrical connection portion 122 and the other contact member 130 that are in contact with each other. And a combination. Thereby, this contact member 130 is made to contact the 1st wall surface 11a or the 2nd wall surface 11b of the electrical connection part 11 inserted between the one end parts 121b and 122b of the 1st and 2nd electrical connection parts 121 and 122. be able to. Therefore, the contact member 130 can electrically connect the electrical connection portion 11 to the first electrical connection portion 121 and the second electrical connection portion 122.

  The contact member 130 is formed to have a spring property by a conductive material such as metal (copper, copper alloy, aluminum, aluminum alloy, etc.). In this example, the contact member 130 is formed by press working such as cutting or bending using a conductive metal plate as a base material.

  The contact member 130 is formed so that the first electrical connection portion 121 and the second electrical connection portion 122 are fitted. Therefore, the contact member 130 is formed in an annular shape or a cylindrical shape. For example, the illustrated contact member 130 includes two annular portions 131 having a rectangular tube shape that are arranged to face each other with the cylinder axis directions aligned and spaced from each other, and four connecting portions that connect the respective annular portions 131. 132 (FIGS. 20 and 21). One end 121 b of the first electrical connecting portion 121 and one end 122 b of the second electrical connecting portion 122 are fitted inside each annular portion 131. Each connection part 132 is each arrange | positioned, for example at the corner part of the two annular parts 131, and connects the corner parts which face each other in the cylinder axis direction.

  Furthermore, the contact member 130 has at least one contact portion 133 that protrudes outward from each annular portion 131 and has elasticity between each annular portion 131 (FIGS. 20 and 21). ). The illustrated contact member 130 has a plurality of contact portions 133 that are protruded in the same direction with an equivalent protrusion amount. This contact portion 133 connects both ends in the cylinder axis direction to the respective annular portions 131, and uses a curved surface provided at the maximum projecting position in the center in the cylinder axis direction as a contact. Each contact portion 133 forms a virtual plane (not shown) by connecting the maximum protruding positions. The illustrated virtual plane is arranged in parallel with each of the opposing wall surfaces 121a and 122a when the first electrical connection portion 121 and the second electrical connection portion 122 are inserted.

  In the mating connector 101, the first electrical connection portion 121 and the second electrical connection portion 122 are fitted into the respective contact members 130 so that the virtual planes are arranged in parallel and spaced apart from each other. . As a result, the contact portions 133 of the contact members 130 are opposed to each other in the direction orthogonal to the opposing wall surfaces 121 a and 122 a of the first electrical connection portion 121 and the second electrical connection portion 122. The interval between the virtual planes is made narrower than the plate thickness of the electrical connection portion 11. Therefore, in each contact member 130, each contact part 133 can be made to contact the 1st wall surface 11a and the 2nd wall surface 11b of the electrical connection part 11 by inserting the electrical connection part 11 between them. Therefore, the first electrical connection part 121 and the second electrical connection part 122 are physically connected to the electrical connection part 11 via the contact member 130 in the terminal accommodation chamber 41 of the second accommodation member 40 of the housing 20. Electrically connected.

  Here, when the contact member 130 is provided, each of the first electrical connection portion 121 and the second electrical connection portion 122 may have the contact portion (bulge portion) described above, and the contact portion (bulge portion) described above. It does not have to have a protruding portion. When the counterpart connector 101 has a contact portion (bulged portion), the counterpart terminal fitting 120 can be shared regardless of the presence or absence of the contact member 130. Here, the contact part (bulging part) is not provided in the 1st electrical connection part 121 and the 2nd electrical connection part 122. FIG.

  The counterpart connector 101 includes a casing 140 that accommodates the counterpart terminal 110 (FIGS. 1, 18, and 19). The housing 140 includes a housing member 150 (FIGS. 1, 18 and 19) in which the mating terminal 110 is housed, and a holding member 160 (see FIGS. 18 and 18) that prevents the housed mating terminal 110 from coming off from the housing member 150. FIG. 19).

  The housing member 150 is formed of an insulating material such as synthetic resin. The housing member 150 houses a first housing 151 that houses a combination of a pair of first electrical connection portions 121 and one contact member 130, and a combination of a pair of second electrical connection portions 122 and the other contact member 130. A second container 152 (FIGS. 1, 18 and 19). The first container 151 is formed so as to surround the first electrical connection portion 121 and the one contact member 130 in a state where the opposing wall surface 121a and the contact portion 133 side of the one contact member 130 are exposed. The second container 152 is formed so as to surround the second electrical connection portion 122 and the other contact member 130 in a state where the opposing wall surface 122a and the contact portion 133 side of the other contact member 130 are exposed. The first container 151 and the second container 152 are arranged to face each other with a space therebetween in a direction orthogonal to the opposing wall surfaces 121a and 122a. The interval is set to a size that does not hinder the insertion of the electrical connection portion 11 between the contact members 130. The housing member 150 is provided with a pair of first housing body 151 and second housing body 152 for each counterpart terminal 110.

  The housing member 150 has a cylindrical body 153 in which the connector insertion / extraction direction is the cylinder axis direction and both ends in the cylinder axis direction are opened (FIGS. 1, 18, and 19). All the combinations of the first container 151 and the second container 152 are extended from the inner space of the cylinder 153 toward the connector insertion direction, and protruded from the opening 153a at one end of the cylinder 153. (FIGS. 1 and 18). In the opening 153b at the other end of the cylindrical body 153, an insertion port 153c for inserting the counterpart terminal 110 is provided for each counterpart terminal 110 (FIG. 19). In addition, a holding portion 153d that holds the first receiving body 151 and the second receiving body 152 and that holds the counterpart terminal 110 is provided inside the cylindrical body 153 (FIG. 19). The counterpart terminal 110 is fixed to the holding portion 153d through a male screw member B1 inserted through the through hole 124a. A female screw member N1 into which the male screw member B1 is screwed is inserted and fitted into the holding portion 153d (FIG. 19).

  The housing member 150 has a flange 154 to be attached to the casing 201 of the power supply circuit 200 outside the cylinder 153 (FIGS. 1, 18, and 19). The flange portion 154 has a through hole 154a through which the male screw member B2 is inserted (FIG. 22), and is fixed to the housing 201 via the male screw member B2 (FIG. 1). The housing 201 is formed with a female screw portion N2 into which the male screw member B2 is screwed (FIG. 22).

  In the cylindrical body 153, the connector insertion direction side (that is, the portion protruding from the housing 201) is closer to the connector fitting portion 31 a of the housing 20 of the connector 1 (connector fitting). 153e (FIGS. 1, 18 and 19). An annular seal member Se11 is attached to the outer peripheral surface of the connector fitting portion 153e. The connector fitting portion 153e is inserted and fitted inside the connector fitting portion 31a. The seal member Se11 is interposed between the connector fitting portion 31a and the connector fitting portion 153e, and is in close contact with both wall surfaces. On the other hand, the connector detaching direction side (that is, the portion embedded in the housing 201) from the flange portion 154 in the cylindrical body 153 becomes a fitting portion 153f with the holding member 160 (FIGS. 18 and 19).

  The holding member 160 is formed of an insulating material such as synthetic resin. The holding member 160 is fitted into the fitting portion 153f on the opening 153b side of the other end of the cylindrical body 153, and closes the insertion port 153c of the counterpart terminal 110. The holding member 160 inserts and fits the fitting portion 153f inward. The holding member 160 becomes a fitting portion with the housing 201 in the counterpart connector 101. Therefore, an annular seal member Se12 is attached to the outer peripheral surface of the holding member 160 (FIGS. 18 and 19).

  The mating connector 101 has such a configuration.

  As described above, the connector 1 is electrically connected to the mating connector 101 by being inserted into the mating connector 101 (FIGS. 23 and 24). The connector 1 of this embodiment is screwed and fixed to the mating connector 101 side in order to maintain a fitting state with the mating connector 101 (that is, an electrical connection state with the mating connector 101). In this example, the connector 1 is fixed to the counterpart connector 101 side by screwing and fixing the shield shell 20B to the housing 201 in the connector fitting state via the coupling body 53 as described above. Here, the connector 1 is configured such that the shield shell 20B is brought into contact with the housing 201 and electrically connected to each other by screw fixing, or the shield shell 20B is connected to the housing 201 via a conductive screw member. Can be electrically connected. The housing 201 is grounded (earthed).

  The connection body 53 is formed so that it can be screwed and fixed to the housing 201 in a connector fitting state. The connector 53 may be brought into contact with the wall surface 201a of the housing 201 in a connector fitting state, and is floated without being brought into contact with the wall surface 201a of the housing 201 in a connector fitting state. It may be. In this example, like the latter, the connection body 53 and the housing 201 are not in direct contact.

  In the connection body 53, screwing and fixing to the housing 201 is performed between two adjacent sub shield bodies 52 arranged in parallel. Between the sub shield bodies 52, a male screw portion B0a of a conductive male screw member B0 used for screwing and fixing is disposed. The illustrated connecting body 53 has a fixing portion 53a used for fixing with screws (FIG. 24). Therefore, the fixing | fixed part 53a is arrange | positioned between the two adjacent sub shield bodies 52 arrange | positioned in parallel. The fixing portion 53a is formed with a through hole 54 used for fixing the screw (FIGS. 3 and 24). The through hole 54 is a hole through which the male screw portion B0a of the male screw member B0 is inserted, and the direction orthogonal to the wall surface 201a of the housing 201 is an axis. Between the two adjacent sub shield bodies 52 arranged in parallel, the male screw portion B0a of the male screw member B0 is arranged along the axis.

Here, the male screw member B0 may be screwed into a female screw portion formed in the housing 201, and is suspended from the wall surface 201a of the housing 201 like a stud bolt. Also good. Fixing portion 53a in the case of those male screw member B0 is screwed to the female thread portion of the housing 201, having a seat surface 53a ₁ of the head is in contact of the male screw member B0 in its screwed state (FIG. 24) . On the other hand, when the male screw member B0 is suspended from the housing 201, a conductive female screw member is screwed into the male screw member B0. The fixing portion 53a of the case has a seat surface 53a ₁ of the female screw member contacts with the screwed state (FIG. 24). In this example, a female screw portion N0 is formed in the housing 201 (FIGS. 1, 22, and 24). Thus, the fixed portion 53a of this exemplary has a seat surface 53a ₁ of the head B0b the male screw member B0 contacts (Figure 24).

Fixing portion 53a is formed so as to seat surface 53a ₁ is disposed between the two sub shield body 52 adjacent arranged in parallel. Thereby, in this shield shell 20B, the head B0b of the male screw member B0 after screwing and fixing (in the case of using a female screw member) is arranged at a position where it is difficult to see. Therefore, in this connector 1, a person (such as a vehicle user) who does not grasp the attachment / detachment work process of the connector 1 in the head B0b easily inserts a tool and releases the screwing and fixing. The occurrence of the situation can be suppressed. Such an effect can be similarly obtained even when a female screw member is used.

To enhance such an effect, for example, the fixing portion 53a is such that the seat surface 53a ₁ is arranged close to the wall surface 201a of the housing 201 than the respective cylinder axes of the two sub shield body 52 adjacent arranged in parallel It is desirable to form. Thus, in this shield shell 20B, the head B0b of the male screw member B0 after screwing and fixing between two adjacent sub shield bodies 52 arranged in parallel (in the case of using a female screw member, a female screw). Member) can be arranged without protruding from the respective sub shield bodies 52. Therefore, in this connector 1, the head B0b is protruded from each sub-shield body 52, or the head B0b is arranged by being screwed and fixed at the periphery of the shield shell 20B. The head B0b after the screwing and fixing becomes difficult to see. Therefore, in this connector 1, it is possible to enhance the effect of suppressing the easy release of screwing and fixing by a person who does not grasp the attaching / detaching work process of the connector 1. Such an effect can be similarly obtained even when a female screw member is used.

Further, for example, the fixing portion 53a includes a cylinder shaft (a cylinder of each of two adjacent sub shield bodies 52 arranged in parallel) with a head B0b of the male screw member B0 (or a female screw member when a female screw member is used). It is desirable to form the seating surface 53a ₁ so as to be disposed closer to the wall surface 201a of the housing 201 than the shaft). As a result, in this shield shell 20B, the head B0b (female screw) of the male screw member B0 after being screwed and fixed at a deep position on the wall surface 201a side between two adjacent sub shield bodies 52 arranged in parallel. When a member is used, a female screw member) can be disposed. Therefore, in this connector 1, the head B0b after screwing and fixing is more difficult to see, and easy release of screwing and fixing can be more appropriately suppressed. Such an effect can be similarly obtained even when a female screw member is used.

Furthermore, it is desirable that the seating surface 53a ₁ is arranged closest to the wall surface 201a of the housing 201 within a range where it can be formed. Thus, in this shield shell 20B, the head B0b (female) of the male screw member B0 after being screwed and fixed at the deepest position on the wall surface 201a side between two adjacent sub shield bodies 52 arranged in parallel. When a screw member is used, a female screw member) can be arranged. Therefore, in this connector 1, the head B0b after screwing and fixing is most difficult to see, and the easy release of screwing and fixing can be most suppressed. Such an effect can be similarly obtained even when a female screw member is used.

Here, it is desirable that the seating surface 53a ₁ is disposed adjacent to the outer peripheral wall 51a of the main shield body 51 so as to be adjacent to the outer peripheral wall 51a. Thereby, in this shield shell 20B, the head B0b of the male screw member B0 after screwing and fixing (in the case of using a female screw member, the female screw member) are adjacent two sub shield bodies 52 arranged in parallel. In addition, the outer peripheral wall 51a of the main shield body 51 is surrounded. Therefore, in this connector 1, since visibility with respect to the head B0b after screwing and fixing can be further reduced, it is possible to further suppress the release of easy screwing and fixing. Such an effect can be similarly obtained even when a female screw member is used.

Specifically, in this example, to form a fixing portion 53a as piece body shaped flaky portion, provided seat surface 53a ₁ to the plane opposite to the plane which is opposed to the wall surface 201a of the housing 201. Further, in this exemplary male screw member B0, a locking member R such as a C-ring is attached to the screw portion B0a side so that a single-piece-shaped fixing portion 53a is interposed between the male screw member B0 and the head B0b (FIG. 1). And FIG. 24). The head B0b and the locking member R sandwich the fixing portion 53a so that the male screw member B0 can rotate around the axis, and the male screw member B0 is held by the fixing portion 53a.

In this example, the male screw member B0 is screwed into the female screw portion N0 in a state where the connector 1 and the mating connector 101 have been fitted. Thereby, the connector 1 can hold | maintain the fitting state (electrical connection state with the other party connector 101) with the other party connector 101, and the 1st shield member (shield shell 20B) and the 2nd shield member 71 can be electrically connected to the housing 201 to exert shielding performance. Then, the connector 1, by the seating surface 53a ₁ of the fixed portion 53a arranged as described above, since easy release of the screw fixing by the male screw member B0 and the female screw portion N0 is suppressed, the vehicle Release of the easy fitting state between the connector 1 and the mating connector 101 by the user or the like can be suppressed. Therefore, this connector 1 can suppress the occurrence of a situation in which an unfamiliar vehicle user or the like forgets to fix with screws when the connector 1 and the mating connector 101 are re-fitted, and the shielding performance is reduced. Can continue to demonstrate.

  The connecting body 53 has a cylindrical work space 53b for inserting a tool (not shown) such as a socket into the head B0b and rotating the head B0b around the axis with the tool. (FIGS. 1, 13, 15, and 24).

  By the way, the connector 1 of the present embodiment has a head B0b of the male screw member B0 after screwing and fixing (in the case of using a female screw member, the female screw member) in order to make it easier to suppress the release of the screwing and fixing. The insertion of the tool into the screw member is physically avoided. In order to embody this, the connector 1 has a relative movement along its outer peripheral wall 52c between one of two adjacent sub-shield bodies 52 arranged in parallel between a retracted position and a preventive position. Possible movable members 91 are provided (FIGS. 1 to 5, FIGS. 13 to 15, and FIGS. 23 to 29).

  The retracted position is a position where the tool can be inserted into the head B0b of the male screw member B0 after screwing and fixing (a female screw member when a female screw member is used) (FIGS. 1 to 5). 15, FIG. 23, FIG. 25 and FIG. 28). In this connector 1, when the movable member 91 is in the retracted position, a tool is inserted into the head B0b of the male screw member B0 after screwing and fixing, and the male screw member B0 is engaged with the female screw portion N0. It can be canceled. On the other hand, the prevention position is a position where a tool cannot be inserted into the head B0b of the male screw member B0 after fixing with a screw (a female screw member when a female screw member is used) (FIG. 24). 26, 27 and 29). In this connector 1, when the movable member 91 is in the prevention position, the movable member 91 obstructs the insertion of the tool. Therefore, the tool cannot be inserted into the head B 0 b of the male screw member B 0 after screwing and fixing. The screwed state of the male screw member B0 with respect to the female screw portion N0 cannot be released.

  In the connector 1, after fixing the screw to the housing 201, the movable member 91 is relatively moved to the prevention position. Thereby, in this connector 1, unless the movable member 91 is relatively moved to the retracted position, the screw fixing to the housing 201 cannot be released. Therefore, if the worker is a person who has grasped the attachment / detachment work process of the connector 1, the movable member 91 is relatively moved from the prevention position to the retracted position, and the screw fixing of the connector 1 to the housing 201 is fixed. It can be canceled. On the other hand, the movable member 91 at the prevention position can make a person who does not grasp the attachment / detachment work process (such as a user of the vehicle) hesitate to perform an easy screw release operation. Therefore, in this connector 1, it is possible to suppress the release of easy screw fastening by a person who does not grasp the attaching / detaching work process.

  Specifically, the movable member 91 has a base 91a that is attached to the outer peripheral wall 52c of the sub shield body 52 to be attached so as to be relatively movable (FIGS. 1, 4, 5, 13 to 15, and 23). And FIGS. 25 to 29). The illustrated movable member 91 is formed so as to be relatively rotated along the circumferential direction of the sub shield body 52 between the retracted position and the prevention position. Therefore, the base 91a is formed in an arc shape, and is fitted into the outer peripheral wall 52c of the sub shield body 52 so as to be relatively rotatable.

  Furthermore, the movable member 91 has a cover portion 91b that covers the head B0b of the male screw member B0 after screwing and fixing (a female screw member when a female screw member is used) (FIGS. 1, 4, 5, and 5). 13 to 15, FIG. 23 and FIG. 25 to FIG. 29). The cover portion 91b is disposed on the locus of insertion of the tool into the head B0b (or the female screw member in the case of using the female screw member) of the male screw member B0 after screwing and fixing at the prevention position. The cover portion 91b protrudes outward in the radial direction from the base portion 91a. The cover portion 91b is formed so that it can be retracted to a position deviating from the tool insertion locus at the retracted position and can be disposed on the tool insertion locus at the prevention position. Therefore, when the movable member 91 is in the retracted position, the tool can be inserted into the head B0b of the male screw member B0 after screwing and fixing (a female screw member when a female screw member is used). On the other hand, when the movable member 91 is in the prevention position, the cover 91b obstructs the insertion of the tool, so the head B0b of the male screw member B0 after screwing and fixing (in the case of using a female screw member, the female screw). The tool cannot be inserted into the member. In this illustration, a rectangular piece-like cover portion 91b is protruded outward in the radial direction from one end of the base portion 91a in the circumferential direction. Here, the cover portion 91b is disposed in the columnar work space 53b of the tool described above at the prevention position.

  The movable member 91 gives flexibility to at least the base 91a. For example, the movable member 91 is formed of synthetic resin or the like.

  Here, relative rotation in the circumferential direction of the movable member 91 is guided to the outer peripheral wall 52c of the sub shield body 52 to which the movable member 91 is attached, and relative movement in the cylinder axis direction of the movable member 91 is locked. Two guide portions 57 are provided (FIGS. 1, 3, 13, 14, 23, and 25 to 29). The respective guide portions 57 are arranged to face each other with an interval in the cylinder axis direction. One guide portion 57 is a portion that guides and locks one end portion in the axial direction of the base portion 91a of the movable member 91, and locks the end surface in the axial direction and the outer peripheral surface at the one end portion. The other guide portion 57 is a portion that guides and locks the other end portion in the axial direction of the base portion 91a of the movable member 91, and locks the end surface in the axial direction and the outer peripheral surface at the other end portion. The illustrated guide portion 57 is formed in an L shape that protrudes radially outward from the outer peripheral wall 52c and protrudes in the cylindrical axis direction of the outer peripheral wall 52c from the end portion on the protruding direction side. The base 91a of the movable member 91 has notches 91c at both ends in the axial direction (FIGS. 13, 14, 23, and 26). The movable member 91 can be attached to the outer peripheral wall 52c of the sub shield body 52 to be attached so as to be movable relative to each other by inserting each guide portion 57 through each notch portion 91c. Each notch portion 91c is formed so as to be disposed on the prevention position side in the circumferential direction with respect to each guide portion 57 when in the retracted position (FIGS. 23 and 26).

Further, a retracting holding mechanism M1 for holding the movable member 91 at the retracted position is provided between the movable member 91 and the sub shield body 52 to which the movable member 91 is attached (FIG. 28). In this figure, only the shield shell 20B and the movable member 91 are shown for convenience. The retracting holding mechanism M1 is provided on the projecting portion 91d (FIGS. 14 and 28) projecting radially inward from the inner peripheral surface of the base portion 91a and the outer peripheral wall 52c of the sub shield body 52 to be attached. And a groove 52c ₁ (FIGS. 13 and 28) for inserting the protruding portion 91d at the retracted position.

The protruding portions 91d and the groove 52c _1, when rotated relative from the retracted position of the movable member 91 to the sub-shield 52 to the preventing position, the protruding portion 91d is formed so that it can escape from the groove 52c _1. Therefore, the protruding portion 91d and the groove 52c ₁ are allowed to respectively inclined end faces _91d 1, _{52c 11} of the cover portion 91b side in the circumferential direction with respect to the radial direction and the circumferential direction (FIG. 28). On the other hand, the protruding portion 91d and the groove 52c ₁ is the preventing position side from the retracted position of the movable member 91 to the sub-shield 52 is formed so as not to rotate relative to the opposite direction. Therefore, the protruding portion 91d and the groove 52c ₁ is formed along the end face _91d 2, _{52c 12} on the opposite side in the radial direction of the cover portion 91b side in the circumferential direction, the end face _91d 2, _{52c 12} mutually engaging one another Try to fit each other (FIG. 28).

  In the connector 1, the movable member 91 can be held at the retracted position by the retracting holding mechanism M <b> 1, so that it is possible to suppress a decrease in workability when the male screw member B <b> 0 is screwed.

Further, a prevention holding mechanism M2 for holding the movable member 91 at the prevention position is provided between the movable member 91 and the sub shield body 52 to which the movable member 91 is attached (FIG. 29). In this figure, only the shield shell 20B and the movable member 91 are shown for convenience. Here, the cylindrical work space 53 b of the tool described above partially cuts the outer peripheral wall 52 c of the sub shield body 52 on the relative rotation locus of the movable member 91. Thus, the outer peripheral wall 52c is in its relative rotation locus, and a corner portion 52c ₂ which intersects with the wall surface 53b ₁ of the working space 53b (FIGS. 13, 28 and 29). Prevention during holding mechanism M2 in this example utilizes a protrusion 91d of the corner 52c ₂ and the movable member 91. In the prevention when holding mechanism M2, the protrusion 91d is entering the working space 53b with the relative rotation in the preventing position of the movable member 91, the wall surface 53b of the working space 53b at the corners 52c ₂ and the projecting portions 91d in the circumferential direction ₁ is locked. As a result, the prevention holding mechanism M2 can hold the movable member 91 in the prevention position.

  Since the base 91a has flexibility in the movable member 91, the protrusion 91d is extracted from the work space 53b by the operator bending the cover 91b side of the base 91a outward in the radial direction. be able to. Therefore, the movable member 91 can also perform relative rotation from the prevention position to the retracted position.

  In the connector 1, the movable member 91 can be held at the prevention position by the prevention holding mechanism M <b> 2, so that the cover portion 91 b can be continuously placed on the insertion path of the tool at the prevention position. Therefore, this connector 1 can continue to suppress the release of easy screw fixing by a person who does not grasp the attaching / detaching work process.

  As described above, the connector 1 and the connector-attached electric wire WH according to the present embodiment are positions where it is difficult to see the head B0b of the male screw member B0 after screwing and fixing (a female screw member when using a female screw member). Therefore, it is possible to suppress easy release of screwing and fixing by a person who does not grasp the attaching / detaching work process of the connector 1 (such as a vehicle user). Further, the connector 1 and the electric wire WH with the connector according to the present embodiment cannot insert a tool into the head B0b of the male screw member B0 after screwing and fixing (a female screw member when a female screw member is used). Since the movable member 91 is provided as described above, from this point as well, it is possible to suppress easy release of screwing and fixing by a person who does not grasp the attaching / detaching work process of the connector 1 (such as a vehicle user). Accordingly, the connector 1 and the electric wire WH with the connector according to the present embodiment can reduce the chance of inadvertent attachment / detachment from the mating connector 101 by such a person, so that the screwed and fixed state to the housing 201 is maintained. Thus, the desired shielding performance can be maintained.

  By the way, in the previous illustration, the movable member 91 that rotates relative to the outer peripheral wall 52c of the sub shield body 52 in the circumferential direction is shown. In the connector 1, the following movable member 92 may be used instead of the movable member 91 (FIGS. 30 to 34). The movable member 92 is formed so as to be relatively moved along the cylinder axis direction of the sub shield body 52 between the retracted position and the prevention position. Here, the retracted position is shown in FIGS. 31 and 32, and the prevention position is shown in FIGS. The movable member 92 has a base portion 92a and a cover portion 92b similar to the movable member 91.

  In addition, the connector 1 includes a retracting holding mechanism M1 and a preventing holding mechanism M2 as in the case of the movable member 91. The outer peripheral wall 52c of the sub shield body 52 to which the movable member 92 is attached is provided with a first projecting portion 58 and a second projecting portion 59 that are arranged to face each other with a gap in the cylinder axis direction (FIG. 30 to FIG. 30). 34). Here, the first protrusion 58 is disposed on the opening 52a side, and the second protrusion 59 is disposed on the main shield body 51 side, and the first protrusion 58 and the second protrusion 59 are retracted. The holding mechanism M1 and the prevention holding mechanism M2 are configured. In this case, when the movable member 92 is disposed closer to the opening 52a than the first projecting portion 58, the retracted position is set (FIGS. 31 and 32), and the movable member 92 has the first projecting portion 58 and the second projecting portion. The time when it is inserted between the portions 59 is taken as the prevention position (FIGS. 33 and 34).

  When in the retracted position, the first projecting portion 58 serves as a retracting holding mechanism M1, and the first projecting portion 58 engages the movement of the base 92a of the movable member 92 toward the preventing position. In this example, when the movable member 92 is relatively moved from the retracted position to the prevention position, the end surface 58a on the opening 52a side of the first protrusion 58 is inclined so that the base 92a can get over the first protrusion 58. (FIGS. 30 to 34).

  On the other hand, at the prevention position, the first protrusion 58 and the second protrusion 59 serve as the prevention holding mechanism M2, and the base of the movable member 92 inserted between the first protrusion 58 and the second protrusion 59 is provided. 92a is sandwiched between the first protrusion 58 and the second protrusion 59 in the cylinder axis direction.

  Regarding the movable member 92, at least the base 92a has flexibility. Therefore, the movable member 92 allows the base 92a to be extracted from between the first protrusion 58 and the second protrusion 59 when the operator bends the cover 92b side of the base 92a outward in the radial direction. it can. Therefore, the movable member 92 can also perform relative movement from the prevention position to the retracted position.

  The movable member 92 restricts relative rotation of the sub shield body 52 relative to the outer peripheral wall 52c by locking the other end portion opposite to the one end portion having the cover portion 92b to the connecting body 53 in the circumferential direction ( FIG. 35). This relative rotation restriction can be performed at both the retracted position and the prevention position. In this figure, the prevention position is given as an example.

  Even if such a movable member 92 is used, the connector 1 and the connector-attached electric wire WH of the present embodiment can achieve the same effects as those of the movable member 91 described above.
