In each of these directions, when proceeding with the connector 1 as the main body, the direction of the connector 1 with respect to the counterpart connector 101 is indicated. The direction to the connector 1 is shown.

  The connector 1 of the present embodiment may be a female connector having a female terminal or a male connector having a male terminal as long as it has a configuration described in detail below. Further, the connector 1 of the present embodiment may be configured as a shielded connector for suppressing intrusion of noise from outside. In the following examples, the connector 1 will be described as a male connector, and the mating connector 101 will be described as a female connector. The connector 1 is described as a shield connector.

  The connector 1 of the present embodiment includes a terminal fitting 10 and a housing 20 (FIGS. 4 and 5).

  The terminal fitting 10 of the present embodiment is formed into a male mold with a conductive material such as a metal (copper, copper alloy, aluminum, aluminum alloy, etc.). In this example, a male terminal fitting 10 is formed by press working such as cutting or bending using a conductive metal plate as a base material. The terminal fitting 10 includes an electric connection portion 11 electrically connected to a mating terminal 110 of the mating connector 101 described later, and an electric wire connection portion 12 electrically connected to a terminal of the electric wire We.

  The electrical connection 11 in this example is formed in a male shape. The electric connection portion 11 is formed in a flat plate shape having two flat wall surfaces (a first wall surface 11a and a second wall surface 11b) (FIG. 9). Here, the electrical connection portion 11 is formed in a rectangular flat plate shape, and the first wall surface 11a and the second wall surface 11b are arranged to face each other in a parallel state. The electrical connection portion 11 uses at least one of the first wall surface 11a and the second wall surface 11b as a contact portion for making a physical and electrical connection with the counterpart terminal 110. Here, as will be described later, since the counterpart terminal 110 has two electric connection portions (the first electric connection portion 121 and the second electric connection portion 122), the opposite terminal 110 is electrically connected to each electric connection portion. As described above, the first wall surface 11a and the second wall surface 11b are used as contact portions.

  The illustrated electric wire connection unit 12 physically and electrically connects to a terminal of the electric wire We. The wire connection portion 12 may be crimped to the end of the wire We by crimping or the like, or may be fixed by welding or the like. The illustrated wire connection portion 12 is crimped to the end of the wire We.

In the electrical connection portion 11, one end in the axial direction is the one end 11c, and the other end in the axial direction is the other end 11d (FIGS. 8 and 9). The electrical connection portion 11 has two end faces (first end face 11e and second end face 11f) arranged opposite to the two end parts 11c and 11d arranged opposite to each other (FIG. 8). The first end face 11e and the second end face 11f are arranged in parallel to face each other in a direction perpendicular to the axial direction of the terminal fitting 10 and the direction perpendicular to the first and second wall surfaces 11a and 11b. In the electric connection portion 11, the first end face 11e and the second end face 11f with respect to the imaginary axis P form substantially rectangular plates having the same shape.

  The connector 1 of the present embodiment includes the terminal fittings 10 for each pole number, for example. Here, two terminal fittings 10 are provided (FIG. 5). The connector 1 is shown as being provided with a plurality of identical terminal fittings 10 in the housing 20. However, the example terminal fitting 10 and a terminal fitting having a different shape from the example terminal fitting 10 are different from each other. They may be mixed.

  Subsequently, the housing 20 of the present embodiment will be described.

  The housing 20 of the present embodiment includes a housing 20A in which the terminal fitting 10 is housed (FIGS. 2 to 5 and 10). Further, the housing 20 of the present embodiment includes a shield shell 20B that accommodates the space from the container 20A to the terminal of the electric wire We inside and covers it from the outside (FIGS. 1 to 5). Furthermore, the housing 20 of the present embodiment includes a holding member 20C that suppresses the detachment of the terminal fitting 10 from the housing 20A on the electric wire We side (FIGS. 4 and 5).

  First, the container 20A will be described.

  The container 20A is formed of an insulating material such as a synthetic resin. The container 20A accommodates the electric connection portion 11 in an accommodation space 33 described below and makes the electric wire connection portion 12 protrude outward. The container 20A of the present embodiment is roughly divided into a first container 30 and a second container 40 (FIGS. 2 to 5 and 10).

  The first housing member 30 is formed into a cylindrical body having at least one end opened in the cylindrical axis direction. Therefore, the first housing member 30 has the cylindrical outer peripheral wall 31 (FIGS. 3 to 5 and 10). In the first housing member 30 of this example, the outer peripheral wall 31 is formed in a rectangular cylindrical shape, and one end in the cylinder axis direction is opened and the other end is closed. In the first housing member 30, the counterpart terminal 110 is inserted into the inner housing space 33 (FIGS. 2 and 10) from the opening 32 (FIGS. 2, 4 and 10) at one end thereof along the cylinder axis direction. Is done. However, strictly speaking, the counterpart terminal 110 is inserted into the housing space 33 from the opening 32 via the second housing member 40 as described later.

  In the outer peripheral wall 31, the end on the opening 32 side becomes a fitting portion (connector fitting portion) 31a of the mating connector 101 with a connector fitting portion 153e described later (FIGS. 4 and 10). The connector fitting portion 153e is inserted and fitted inside the connector fitting portion 31a. An annular seal member Se1 is concentrically attached to the outer peripheral surface of the connector fitting portion 31a (FIGS. 4, 5, and 10).

  The outer peripheral wall 31 has an insertion hole 34 for inserting the terminal fitting 10 into the housing space 33 from the front end on the side of the electrical connection portion 11 (FIGS. 5 and 10). In the illustrated first housing member 30, the electric connection portion 11 is housed in the inner housing space 33, while the wire connection portion 12 is projected outward from the insertion hole 34 (FIG. 4).

  Here, the insertion hole 34 is provided for each terminal fitting 10. Therefore, two insertion holes 34 are formed in the outer peripheral wall 31 in this example (FIGS. 5 and 10). The respective insertion holes 34 are formed and arranged so that the respective terminal fittings 10 are inserted with their respective axial directions being the same. That is, here, the axial direction of the terminal fitting 10 is the direction in which the terminal fitting 10 is inserted into the accommodation space 33 (hereinafter, referred to as “terminal insertion direction”). Furthermore, each of the insertion holes 34 has a state in which each of the terminal fittings 10 has the first and second end surfaces 11 e and 11 f of the electrical connection portion 11 oriented in the cylinder axis direction of the outer peripheral wall 31 (that is, the electrical connection portion 11).

  The illustrated first housing member 30 has a guide portion 35 for guiding the insertion of the terminal fitting 10 into the housing space 33 through the insertion hole 34 (FIGS. 4 and 10). For example, the insertion hole 34 continues to the wall 36 at the other end of the outer peripheral wall 31 in the cylinder axis direction. Therefore, the guide portion 35 is provided on the wall surface 36 a of the wall body 36 on the side of the housing space 33. The guide portion 35 is provided for each terminal fitting 10. Therefore, the guide portion 35 is provided at two places on the illustrated wall surface 36a.

The illustrated guide portion 35 has two protruding portions 35a that protrude from the wall surface 36a in the cylinder axis direction of the outer peripheral wall 31 and extend in the terminal insertion direction (FIG. 10). The respective protruding portions 35a are opposed to each other with an interval therebetween. The interval is set to a size equal to the thickness of the electric connection portion 11 within a range that does not hinder insertion of the electric connection portion 11 into the accommodation space 33. Therefore, in the guide portion 35, a groove (hereinafter, referred to as a “guide groove”) 35b along the terminal insertion direction is formed between the respective projecting portions 35a (FIGS. 4 and 10). In the terminal fitting 10, the electrical connection portion 11 is guided from one end 11c side along the guide groove 35b. Further, by setting the guide groove 35b to the same size as the plate thickness of the electric connection portion 11 as described above, the rattling of the electric connection portion 11 between the respective projecting portions 35a can be suppressed. . Incidentally, the groove bottom 35b ₁ of the exemplary guide groove 35b is raised on the opening 32 side of the wall surface 36a (FIG. 4).

Furthermore, this exemplary guide portion 35 has a guide wall surface 35c that guides one end 11c side of the electrical connection portion 11 inserted from the insertion hole 34 to the guide groove 35b (FIGS. 4 and 10). The guide wall surface 35c is an inclined surface that guides _one end 11c side of the electrical connection portion 11 from the wall surface 36a to the groove bottom 35b1 of the guide groove 35b.

  The second housing member 40 is formed into a polyhedron that matches the shape of the housing space 33 of the first housing member 30 (FIGS. 10 and 11). Then, the second housing member 40 is housed in the housing space 33 from the opening 32 of the first housing member 30 along the cylinder axis direction (FIGS. 2, 4, 5, and 10). The second housing member 40 houses the electrical connection portion 11 of the terminal fitting 10 in its own state in a state where the housing in the housing space 33 is completed (FIG. 4).

  The second housing member 40 has a terminal housing chamber 41 in which the electrical connection portion 11 is housed in the housing space 33 (FIGS. 4, 5, and 10 to 12). As the second housing member 40 is inserted into the housing space 33, the terminal housing chamber 41 houses the electrical connection portion 11 housed in the housing space 33 from the opening 41a (FIGS. 5, 10 and 11). Begin to. When the housing of the second housing member 40 in the housing space 33 is completed, the housing of the electrical connection portion 11 is completed in the terminal housing chamber 41. Therefore, the second housing member 40 has the notch 42 that allows the terminal housing chamber 41 to communicate with the outside on the outer peripheral surface side (FIGS. 5, 10, and 11). The electric wire connection part 12 is projected from the notch part 42 to the outside of the second housing member 40. The notch 42 is inserted into the insertion hole 34 in a state where the second accommodation member 40 is accommodated in the accommodation space 33 so that the electric wire connection portion 12 projects outward from the insertion hole 34 of the first accommodation member 30. They are arranged facing each other.

  When the fitting of the connector 1 and the mating connector 101 (hereinafter referred to as “connector mating”) is completed in the terminal accommodating chamber 41, first and second electrical connection portions 121, described later, of the mating terminal 110 are provided. 122 and two contact members 130 are accommodated. In this terminal accommodating chamber 41, each contact member 130 comes into contact with the first wall surface 11a and the second wall surface 11b of the electric connection portion 11, respectively, and connects them physically and electrically. Therefore, the second housing member 40 has the terminal insertion opening 43 for inserting the counterpart terminal 110 into the terminal housing chamber 41 (FIGS. 2, 3, 10, and 12). The terminal insertion opening 43 is formed so as to be arranged on the opening 32 side of the first housing member 30 in a state where the second housing member 40 is housed in the housing space 33, and the terminal is inserted in the cylinder axis direction of the outer peripheral wall 31. It is arranged to face the accommodation room 41. Therefore, one of the first end face 11 e and the second end face 11 f of the electric connection portion 11 accommodated in the accommodation space 33 is opposed to the terminal insertion opening 43.

  The second housing member 40 has a communication chamber 44 that allows the terminal housing chamber 41 and the terminal insertion opening 43 to communicate with each other in the axial direction of the outer peripheral wall 31 (FIGS. 2, 3, 10, and 12). Therefore, in the electrical connection part 11, when housed in the terminal housing chamber 41, one of the first end face 11 e and the second end face 11 f is arranged to face the terminal insertion port 43 via the communication chamber 44.

  The second housing member 40 has a contact prevention portion 45 for stopping a finger of an operator or the like so that the finger does not come into contact with the electrical connection portion 11 via the terminal insertion port 43 (FIGS. 2 to 4, 10, and 10). 12). The contact prevention part 45 is formed and arranged so that a finger does not reach the electric connection part 11 through the terminal insertion opening 43. For example, the contact prevention unit 45 may be configured to connect at least a part of the end face (the first end face 11 e or the second end face 11 f) of the electric connection unit 11 arranged to face the terminal insertion port 43 in the cylinder axis direction of the outer peripheral wall 31. It is arranged to cover from the 43 side. Further, the contact prevention portion 45 is provided in the communication chamber 44 so as not to hinder the insertion of the counterpart terminal 110 into the terminal accommodating chamber 41.

  The illustrated contact prevention portion 45 is formed in a flat plate shape having two flat wall surfaces, and the two wall surfaces are formed in the communication chamber 44 so as to extend along the cylinder axis direction of the outer peripheral wall 31. Here, the contact prevention portion 45 is formed in a rectangular flat plate shape. And this contact prevention part 45 is arrange | positioned so that the communication room 44 may be divided into two rooms in the orthogonal direction with respect to the 1st and 2nd wall surfaces 11a and 11b of the electrical connection part 11. FIG. That is, the communication chamber 44 is divided into the first divided communication chamber 44a and the second divided communication chamber 44b in the orthogonal direction by the contact prevention unit 45 (FIGS. 2, 3, 10, and 12). Further, here, the terminal insertion port 43 is also divided into a first divided insertion port 43a and a second divided insertion port 43b in the orthogonal direction by the contact preventing portion 45 (FIGS. 2, 3, and 10). And FIG. 12). Therefore, a first electrical connection portion 121 of the counterpart terminal 110, which will be described later, is inserted into the terminal accommodating chamber 41 via the first divided insertion opening 43a and the first divided communication chamber 44a. Further, a second electric connection portion 122 of the counterpart terminal 110, which will be described later, is inserted into the terminal accommodating chamber 41 via the second divided insertion opening 43b and the second divided communication chamber 44b.

In the terminal accommodating chamber 41, one of the contact members 130 contacts the first wall surface 11 a of the electric connection portion 11, and electrically connects the electric connection portion 11 to the first electric connection portion 121. Further, in this example, after the combination of the pair of second electrical connection portions 122 and the other contact member 130 described later and the second container 152 are inserted into the second divided communication chamber 44b from the second divided insertion opening 43b. Is inserted into the terminal accommodating chamber 41. In the terminal accommodating chamber 41, the other contact member 130 comes into contact with the second wall surface 11 b of the electric connection portion 11, and electrically connects the electric connection portion 11 to the second electric connection portion 122. Therefore, in the second accommodation member 40, the first divided insertion port 43a, the second divided insertion port 43b, the first divided communication chamber 44a, the second divided communication chamber 44b, and the contact prevention section 45 are inserted so that these can be inserted. Are formed and arranged.

  The second housing member 40 has a terminal holding portion 46 for holding the held portion 13 (FIGS. 3, 4, and 6 to 9) of the terminal fitting 10 so that the electric connection portion 11 does not come out of the terminal housing chamber 41. (FIGS. 4 and 11). The terminal holding part 46 is formed so as to hold the held part 13 so that the electrical connection part 11 does not come out of the terminal accommodating chamber 41 (FIG. 4). The held portion 13 and the terminal holding portion 46 are formed and arranged so as to be able to hold at least one of the tip side and the base side of the terminal fitting 10. However, in the terminal fitting 10 of this example, the electric wire connection portion 12 is projected outward of the housing 20A. Therefore, the base side of the terminal fitting 10 where the held part 13 is arranged refers to the end 11 d of the electric connection part 11 on the wire connection part 12 side. For example, here, the held portion 13 is formed as an inserted portion at the tip of the terminal fitting 10, and the terminal holding portion 46 is inserted into the held portion 13 together with the insertion of the second housing member 40 into the housing space 33. It is formed as an insertion portion. The held portion 13 and the terminal holding portion 46 lock the movement of the terminal fitting 10 in the terminal insertion direction with respect to the housing space 33 and the movement of the terminal fitting 10 in the direction opposite to the terminal insertion direction. It is formed so that

  Specifically, the held portion 13 in this example is formed in a T-shape protruding along the virtual axis P from the tip (one end portion 11c) of the electrical connection portion 11. The held portion 13 includes a T-shaped first wall surface 13 a (FIG. 6, FIG. 8, and FIG. 9) disposed on the same plane as the first wall surface 11 a of the electric connection portion 11, And a T-shaped second wall surface 13b (FIGS. 7 and 9) disposed on the same plane as the second wall surface 11b. Further, the held portion 13 has a T-shaped shaft portion 13c having a central axis disposed on the virtual axis line P, and an intersecting portion 13d perpendicular to the shaft portion 13c at the tip of the shaft portion 13c. (FIGS. 6 to 9). The held portion 13 uses a notched groove 13e (FIGS. 4 and 6 to 9) formed between the one end portion 11c of the electric connection portion 11 as an inserted portion. is there. The grooves 13e are formed at two places around the virtual axis P.

  In the illustrated example of the held portion 13, both shapes centering on the virtual axis P are the same in directions orthogonal to the axial direction and the orthogonal directions to the first and second wall surfaces 13 a and 13 b. Is formed. Therefore, the held portion 13 can use both the groove portions 13e as the inserted portion. For example, when the terminal fitting 10 has the first end face 11e facing the terminal insertion opening 43 in the terminal accommodating chamber 41, one of the two grooves 13e is used as an inserted part. In the terminal fitting 10, when the second end face 11f is arranged to face the terminal insertion opening 43 in the terminal accommodating chamber 41, the other of the two groove portions 13e is used as an inserted portion.

The terminal holding portion 46 is inserted into the groove 13 e of the held portion 13 in a state where the second housing member 40 is housed in the housing 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 the illustrated terminal holding portion 46, the remaining portion of the wall portion 41 b having the bottom portion of the groove portion 41 b ₁ as an apex is used as an insertion portion into the held portion 13. In this illustrative of the held portion 13 and the terminal holding portion 46, as the second housing member 40 is gradually inserted into the accommodation space 33, the groove 13e, 41b ₁ between mating begins a. In the held portion 13 and the terminal holding portion 46, the insertion of the remaining portion of the wall portion 41b into the groove portion 13e is completed with the completion of the housing of the second housing member 40 in the housing space 33, and the terminal housing chamber. At 41, the electrical connection portion 11 can be held in the housed 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 arranged outside the outer peripheral surface of the second housing member 40 (FIG. 3 and FIG. 4). Therefore, in the housing 20A, an annular gap 21 is provided between the inner peripheral surface of the first housing member 30 and the outer peripheral surface of the second housing member 40 (FIGS. 3 and 4). The interval between the gaps 21 is set to a size that allows the arrangement of the intersection 13d, but does not allow a finger of an operator or the like to enter. In this connector 1, a continuity check can be performed by using the intersection 13d arranged in the gap 21.

By the way, in the above-described guide portion 35, it is possible to suppress the rattling of the electric connection portion 11 between the respective projecting portions 35a. The electrical connections 11, in a state where the second housing member 40 is received in the receiving space 33, facing the groove bottom 35b ₁ of one guide groove 35b of the first end surface 11e and the second end surface 11f The other of them is arranged to face the end face 45a of the contact prevention section 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 Is also good. That is, the first housing member 30 and the second housing member 40 may be formed so as to sandwich and hold the electric connection portion 11 in a state where the housing between the first housing member 30 and the second housing member 40 is completed. Thereby, this connector 1 can enhance the effect of preventing the electrical connection portion 11 from being detached from the terminal accommodating chamber 41 by the terminal holding portion 46 and suppress the rattling of the electric connection portion 11 in the terminal accommodating chamber 41. be able to. Therefore, this connector 1 can improve the vibration resistance, and can improve the workability of fitting with the mating connector 101. In this exemplary connector 1, in order to obtain such an effect, the first housing member 30 and the second housing member 40 are jointly fastened to the shield shell 20B with an axial force in the cylinder axis direction, as described later.

  In the second housing member 40, a combination of the terminal housing chamber 41, the notch 42, the terminal insertion opening 43, the communication chamber 44, the contact prevention part 45, and the terminal holding part 46 is provided for each terminal fitting 10. In each combination, the plurality of terminal fittings 10 are arranged so as to be accommodated in the same axial direction and the terminal insertion direction with respect to the accommodation space 33. In this example, two combinations are provided. One of the combinations is a state in which the electric connection portion 11 of the terminal fitting 10 has the first end face 11e disposed facing the terminal insertion opening 43 (that is, the first and second wall surfaces 11a and 11b are connected to the outer peripheral wall 31). (In the axial direction of the cylinder). The electric connection portion 11 is inserted into the terminal accommodating chamber 41 from the first end face 11e side. The other combination is a state in which the electrical connection portion 11 of the terminal fitting 10 has the second end face 11f opposed to the terminal insertion opening 43 (that is, the first and second wall surfaces 11a and 11b are connected to the outer peripheral wall 31). It is formed and arranged so as to be accommodated in the terminal accommodating chamber 41 in a state of being aligned along the cylinder axis direction). The electric connection portion 11 is inserted into the terminal accommodating chamber 41 from the second end face 11f side.

  Next, the shield shell 20B will be described.

The shield shell 20B includes a main shield body 51 that covers the container 20A from the outside while exposing the opening 32 side, an electric wire connection portion 12 protruding outside the container 20A from the insertion hole 34, and a terminal of the electric wire We. And a sub-shielding body 52 that covers the outside from outside (FIGS. 1 to 5, 13, and 14).

  The main shield body 51 has a cylindrical outer peripheral wall 51a having one end opened and the other end closed (FIGS. 1 to 5, 13, and 14). The illustrated outer peripheral wall 51a is formed in a rectangular tube shape in accordance with the outer shape of the first housing member 30 having a rectangular tube shape. In the main shield body 51, the first housing member 30 is inserted into the inner housing space 51c (FIG. 14) along the cylinder axis direction from the opening 51b (FIGS. 2, 4, and 14) at one end thereof. Is done. The seal member Se1 is in close contact with the inner peripheral surface of the outer peripheral wall 51a in a state where the first housing member 30 is housed in the housing space 51c, and improves the liquid tightness between the connector fitting portion 31a and the main shield body 51. (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. Therefore, two sub-shields 52 are provided here. This sub-shielding body 52 is formed in a cylindrical shape with both ends opened. This exemplary sub-shield body 52 is formed in a cylindrical shape. In the shield shell 20 </ b> B, the sub-shield 52 is projected outward from the main shield 51 from the periphery of the through hole 51 a ₁ of the main shield 51. This exemplary sub-shielding body 52 is protruded such that the cylinder axis direction is along the terminal insertion direction. In the sub-shielding body 52, the terminal fitting 10 is inserted into the inner accommodating space 52b from the opening 52a on the free end side (FIG. 5). The terminal fitting 10 is inserted into the housing space 33 from the tip via the through hole 51 a ₁ of the main shield body 51 and the insertion hole 34 of the first housing member 30.

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

  Here, an annular seal member Se2 is concentrically attached to the end of the electric wire We (FIGS. 4 and 5). The seal member Se2 adheres tightly to the inner peripheral surface of the sub-shielding body 52 in a state where the electric connection portion 11 is housed in the housing space 33, and improves the liquid tightness between the sub-shielding body 52 and the electric wire We ( (Fig. 4).

  The holding member 20C has a cylindrical outer peripheral wall (an outer peripheral wall 62 to be described later) into which an end of the sub-shielding body 52 on the opening 52a side is fitted, and is arranged in a housing space 52b of the sub-shielding body 52. It is a cylindrical member formed so that the electric wire We can be drawn out. The holding member 20C is formed of a conductive material such as a metal. The holding member 20C 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 have both ends opened in the cylinder axis direction. Therefore, a cylindrical gap 63 is formed between the inner peripheral wall 61 and the outer peripheral wall 62 in the holding member 20C (FIG. 14). In the illustrated holding member 20C, an annular opening at one end in the cylinder axis direction in the cylindrical gap 63 is closed by an annular wall (hereinafter, referred to as “annular wall”) 64 (FIG. 13). The holding member 20C inserts and fits the end of the auxiliary shield body 52 on the opening 52a side from the opening 63a (FIG. 14) at the other end in the cylinder axis direction into the cylindrical gap 63. Therefore, in the holding member 20C, the inner peripheral wall 61 is inserted into the accommodation space 52b of the sub-shielding body 52, and the outer peripheral wall 62 covers the outer peripheral surface of the outer peripheral wall 52c of the sub-shielding body 52 (FIGS. 13 to 15). In the holding member 20C, the electric wire We routed in the housing space 52b of the sub-shielding body 52 is guided to a space inside the inner peripheral wall 61, and is drawn outward from an opening at one end of the inner peripheral wall 61. It is.

  The sub-shield body 52 and the holding member 20C hold each other in a fitted state by the lock mechanism L (FIGS. 13 and 14). In this example, two lock mechanisms L are provided. 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 projects radially outward from the outer peripheral wall 52c at the end of the sub-shield body 52 on the opening 52a side. The first engagement body 55 in this example is formed in a claw shape that can hook the second engagement body 65.

  On the other hand, the second engagement body 65 is provided at a position where a part of the outer peripheral wall 62 of the holding member 20C in the circumferential direction is removed. The illustrated second engaging body 65 has a base 65a protruding radially outward from the outer peripheral surface of the inner peripheral wall 61 on the same plane as the annular wall 64 (FIGS. 13 and 14). Further, the illustrated second engagement body 65 has first and second flexible shaft portions 65b and 65c at both ends in the circumferential direction of the base portion 65a, respectively (see FIGS. 13 and 13). 14). The first and second flexible shaft portions 65b and 65c respectively protrude from both ends in the circumferential direction of the base portion 65a in the cylinder axis direction of the holding member 20C and toward the opening 63a. Further, the first and second flexible shaft portions 65b and 65c are arranged at positions equivalent to the outer peripheral wall 62 in the radial direction of the holding member 20C. Furthermore, the second engagement body 65 of this example has an engagement portion 65d that connects the protruding ends 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 the lock mechanism L, by starting to insert and fit the holding member 20C into the end of the sub-shielding body 52 on the opening 52a side, the second engaging body 65 is bent while the first engaging body 65d is bent. Get on. In the lock mechanism L, when the engagement between the sub shield body 52 and the holding member 20C is completed, the engagement portion 65d of the second engagement body 65 rides over the first engagement body 55, and The bending of the united body 65 is eliminated. Thus, in the lock mechanism L, the first engaging member 55 and the engaging portion 65d of the second engaging member 65 are aligned in the cylinder axis direction of the outer peripheral wall 62 so that the holding member 20C does not come off the sub-shielding member 52. It will be in a lockable state.

  Here, the sub-shielding body 52 has a locking body on the outer peripheral wall 52c at the end on the opening 52a side. The locking body is a protruding body protruding from the outer peripheral wall 52c at the end of the sub-shielding body 52 on the side of the opening 52a, and it is desirable that a plurality of such locking bodies be provided on the outer peripheral wall 52c. Further, the holding member 20C has a gap in the outer peripheral wall 62 into which the locking body is inserted. In the lock mechanism L, in a state where the holding member 20C is fitted to the end of the auxiliary shield body 52 on the opening 52a side, and the engagement between the first engagement body 55 and the second engagement body 65 is completed, The locking body is inserted in the gap. Here, two locking bodies (first and second locking bodies 56A and 56B) are provided on the sub-shielding body 52, and two gaps (first and second gaps 66A and 66B) are formed in the holding member. 20C (FIGS. 13 and 14). In the lock mechanism L, the holding member 20C is fitted to the end of the auxiliary shield body 52 on the side of the opening 52a, and the engagement between the first engagement body 55 and the second engagement body 65 is completed. Then, 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 first and second locking members 56A and 56B of this example are projected radially outward from the outer peripheral wall 52c at the end of the sub-shielding 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 first and second locking members 56A and 56B of this example are formed on the outer peripheral wall 52c at the end of the sub-shielding body 52 on the opening 52a side in the circumferential direction of the sub-shielding body 52 by the first engagement member 55. Are formed so as to be interposed therebetween. On the other hand, by providing the first and second gaps 66A and 66B in the outer peripheral wall 62, one end 62a forming one wall surface in the first gap 66A and one wall surface in the second gap 66B are formed. The other end 62b is formed (FIGS. 13 and 14). The illustrated first gap 66A is provided between 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).

  When the first locking body 56A is inserted into the first gap 66A, the first locking body 56A and the first gap 66A are connected to one end 62a of the outer peripheral wall 62 and the first flexible shaft section 65b. Between them, 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 have a circumferential distance between one end of the first locking body 56A in the circumferential direction and one end 62a of the outer peripheral wall 62, and the first locking body 56A. In the circumferential direction between the other end in the circumferential direction and the first flexible shaft portion 65b so as to be as narrow as possible within a range in which the first locking body 56A can be inserted into the first gap 66A. Formed and arranged. Accordingly, the first locking body 56A is attached to one end 62a of the outer peripheral wall 62 or the first flexible shaft 65b when the sub-shielding body 52 and the holding member 20C are relatively rotating in the circumferential direction. On the other hand, it is locked in the circumferential direction. Therefore, the first locking body 56A and the first gap 66A can suppress the relative rotation of the auxiliary shield body 52 and the holding member 20C in the circumferential direction.

  Similarly, when the second locking body 56B is inserted into the second gap 66B, the second locking body 56B and the second gap 66B are connected to the other end 62b of the outer peripheral wall 62 by the second clearance. The second locking body 56B is formed and arranged such that one end and the other end in the circumferential direction of the second locking body 56B are opposed to each other in the circumferential direction with respect to the flexible shaft portion 65c. The second locking body 56B and the second gap 66B are formed and arranged so as to suppress relative rotation in the circumferential direction between the sub-shielding body 52 and the holding member 20C. For example, the second locking body 56 </ b> B and the second gap 66 </ b> B are defined by the circumferential distance between one end of the second locking body 56 </ b> B in the circumferential direction and the other end 62 b of the outer peripheral wall 62 and the second locking body 56 </ b> B. The distance between the other end in the circumferential direction and the second flexible shaft portion 65c in the circumferential direction is narrowed as much as possible within a range in which the second locking body 56B can be inserted into the second gap 66B. Formed and arranged. Thus, the second locking body 56B is attached to the other end 62b of the outer peripheral wall 62 or the second flexible shaft 65c when the auxiliary shield body 52 and the holding member 20C are about to rotate relative to each other in the circumferential direction. On the other hand, it is locked in the circumferential direction. Therefore, the second locking body 56B and the second gap 66B can suppress the 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 electrically connected to the shield shell 20B, in addition to the shield shell 20B as a first shield member (FIGS. 1 to 5 and 15). The second shield member 71 covers the wire We pulled out from the opening 52a together with the end of the sub-shield body 52 on the side of the opening 52a from the outside, thereby suppressing external noise from entering the wire We. . The second shield member 71 is formed in a tubular shape and provided for each terminal fitting 10. Here, two second shield members 71 are provided. In this connector 1, the electric wire We is drawn out from the holding member 20C attached to the opening 52a of the sub-shielding 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-shielding body 52, the holding member 20C, and the electric wire We drawn out of the holding member 20C from the outside. . Thereby, the second shield member 71 can suppress intrusion of noise from the outside into the electric wire We pulled out from the holding member 20C. Specifically, the second shield member 71 in this example is provided as a braid in which a conductive element wire is woven in a tubular and mesh shape. Therefore, the illustrated second shield member 71 has flexibility, and can follow movement such as bending of the inner electric wire We. In the drawings, the specific shape (a mesh or the like) of the second shield member 71 is omitted for convenience of illustration.

  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). The binding band 75 uses a well-known one in this technical field. For example, the binding band 75 is wound around the second shield member 71 and the end of the sub-shield body 52 on the opening 52 a side 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 an end of the sub-shielding body 52 on the opening 52a side.

  Here, the binding band 75 is attached to the outer end wall 62c of the outer peripheral wall 62 of the holding member 20C on the side of the opening 63a and the end surfaces 56a of the first and second locking members 56A and 56B on the side of the main shield body 51 on the side of the auxiliary shield. Winding is performed at a position facing the body 52 in the cylinder axis direction (FIG. 15). As a result, the binding band 75 having an annular shape (here, an annular shape) after being wound is attached to the end face 62c of the outer peripheral wall 62 and the end faces 56a of the first and second locking bodies 56A and 56B by the cylindrical shaft. In the opposite direction. In this example, the end surfaces 56a of the first and second locking members 56A and 56B are projected from the end surface 62c of the outer peripheral wall 62 in the cylinder axis direction. Thus, the end surfaces 56a of the first and second locking members 56A and 56B can be used as locking portions that can lock the tightened binding band 75 in the cylinder axis direction. For example, in the 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 move relatively in the cylinder axis direction, the binding band 75 is locked by the end surfaces 56a of the first and second locking members 56A and 56B. Therefore, in this connector 1, the second shield member 71 can be held in a state of being fastened to the sub-shielding body 52. Accordingly, the connector 1 can maintain the physical and electrical connection between the sub-shielding body 52 and the second shield member 71, and can suppress a decrease in shielding performance. As described above, in the connector 1, the first and second locking members 56A and 56B have a function of holding the second shield member 71 with respect to the sub-shielding member 52, and also have a function of holding the sub-shielding member 52 with respect to the previously-described sub-shielding member 52. It has a function of inhibiting the relative rotation of the holding member 20C. Therefore, this connector 1 can suppress an increase in physique as compared with a connector in which each function is realized in a separate part.

  Further, in this connector 1, the sub-shields 52 of the shield shell 20B are provided for each terminal fitting 10 and the second shield member 71 is connected to each of the sub-shields 52, so that the electric wires We can be individually connected. It is covered with the second shield member 71. Therefore, since the connector 1 can pull out each of the wires We from the sub-shielding body 52 with flexibility as compared with a case where each of the wires We bundled together is covered with one braid, The degree of freedom of the wiring route of each electric wire We can be increased. In addition, since the connector 1 does not need to bundle the electric wires We together, it is possible to suppress the occurrence of thermal interference between the electric wires We. Therefore, in this connector 1, since the diameter of each electric wire We can be suppressed from increasing, the degree of freedom of the routing path of each electric wire We can be further increased.

  In the connector 1, as described above, the wire connection portion 12 of the terminal fitting 10 is protruded from the insulating container 20A, and the projecting wire connection portion 12 is connected to the conductive sub-shielding member 52. It is covered with. Therefore, in this connector 1, an insulator is interposed between the conductive wire connection portion 12 and the sub-shielding body 52, and the insulation distance (space distance) therebetween is increased. The connector 1 includes an insulating tubular member (hereinafter, referred to as an “insulating tube”) 80 that covers the electric wire connection portion 12 and the end of the electric wire We from outside (FIGS. 3 to 5, FIGS. 16 and 17). ).

  The insulating cylinder 80 is formed of an insulating material such as a synthetic resin. This exemplary insulating cylinder 80 has a rectangular tubular body 81 that accommodates the electric wire connection part 12 and the terminal of the electric wire We inward (FIGS. 4, 5, 16, and 17). One end of the cylindrical body 81 in the cylinder axis direction is inserted into the housing space 33 of the first housing member 30 with the wire connection portion 12 housed inward. Therefore, the terminal fitting 10 is inserted into the housing space 33 from the front end of the electrical connection portion 11 through the insertion hole 34 together with one end of the insulating cylinder 80 in the direction of its own cylinder axis. Therefore, in the connector 1, it is desirable that the insertion hole 34 of the first housing member 30 be formed in a substantially rectangular shape, and that the tubular body 81 be formed so as to be fitted into the insertion hole 34. In the housing 20A, the second housing member 40 is inserted into the housing space 33 with one end of the insulating tube 80 and the electrical connection portion 11 being housed in the housing space 33.

  This exemplary insulating cylinder 80 has a locking claw 82 at one end in its own cylinder axis direction (FIGS. 3, 5, 16, and 17). In this example, the locking claws 82 are provided at at least one position 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 cylindrical body 81, and is housed in the housing space 33. The locking claw 82 can be locked to the peripheral portion of the insertion hole 34 in the outer peripheral wall 31 of the first housing member 30 in the cylinder axis direction of the cylindrical body 81 whose one end is housed in the housing space 33 (FIG. 3 and FIG. 17). Therefore, the locking claws 82 can temporarily hold the insulating cylinder 80 on the first housing member 30 until the second housing member 40 is housed in the housing space 33.

  Further, in the connector 1, the locked portion 83 (FIGS. 3, 5, 16 and 17) provided on the insulating tube 80 and the locking portion 47 (FIG. 11 and 17), the movement of the insulating cylinder 80 in the direction of its own cylinder axis with respect to the container 20A 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 protruding shape, and the other is formed in a groove shape into which a counterpart is inserted. The insulating cylinder 80 in this example has a locked portion 83 at one end in its own 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 protruding from one end of the cylinder 81 in the cylinder axis direction. The illustrated locked portion 83 includes a first piece 83a protruding from one end of the cylindrical body 81 in the cylinder axis direction, and a second piece 83b orthogonal to the first piece 83a. It is formed in a letter shape (FIGS. 16 and 17). One end of the insulating tube 80 is inserted into the housing space 33 from the insertion hole 34 such that the direction orthogonal to the L-shaped cross section of the locked portion 83 faces the cylindrical axis direction of the first housing member 30. . The second housing member 40 is provided with a groove-shaped locking portion 47 for housing the second piece 83b in the housing space 33. The locking portion 47 is a groove for each insulating cylinder 80 extending along the cylinder axis direction of the first housing member 30, and is inserted into the housing space 33 of the second housing member 40 and the second piece portion is formed. 83b is inserted along the cylinder axis direction of the first housing member 30. The second piece 83b can be locked by 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, it is possible to suppress the displacement of the insulating cylinder 80 along the cylinder axis direction with respect to the container 20A and the shield shell 20B.

  In this connector 1, the second shield member 71 is covered from the outside with an exterior member CB (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 so as to increase the degree of freedom of the wiring route of the electric wire We. For example, this exterior member CB is provided with bendable cylindrical portions CBa and CBb for each electric wire We pulled out 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 tube 80 is first housed from the distal end. It is housed in the housing 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 20B are screwed and fixed to keep these components in a fixed state. For example, the illustrated main shield body 51 is formed with a female screw portion N whose axis is in the direction of its own cylinder axis (FIGS. 12 and 14). The first housing member 30, the second housing member 40, and the shield shell 20B are fixed by screwing a male screw member B (FIG. 5) to the female screw portion N thereof. The first housing member 30 is formed with a through hole 37 (FIGS. 3, 5, and 12) through which a cylindrical boss 51d (FIGS. 12 and 14) having the female thread N is inserted. Further, a through hole 48 through which the male screw member B is inserted is formed in the second housing member 40 (FIGS. 3, 5, 11, and 12). The axial direction of the through holes 37 and 48 is set in the cylinder axis direction of the outer peripheral wall 31. The boss 51d has the axis in the cylinder axis direction of the outer peripheral wall 51a. Therefore, the first housing member 30, the second housing member 40, and the shield shell 20B are fastened together by the axial force in the cylinder axis direction.

  The connector 1 described above is inserted and fitted into the mating connector 101 and is electrically connected to the mating connector 101 as described above. 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 partner terminal 110 may use itself as a contact part. In this case, the terminal fitting (hereinafter, referred to as “the counterpart terminal fitting”) 120 itself becomes the counterpart terminal 110. On the other hand, the counterpart terminal 110 may have a contact member 130 attached to the counterpart terminal fitting 120.

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

  The counterpart terminal fitting 120 has a first electric connection portion 121 and a second electric connection portion 122 which are arranged facing each other with a space therebetween (FIGS. 20 and 21). Each of the first electrical connection portion 121 and the second electrical connection portion 122 is 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 first electrical connection portion 121 and the second electrical connection portion 122 in this example are each formed in the same shape. In this counterpart terminal fitting 120, one of two wall surfaces (hereinafter, referred to as “opposing wall surfaces”) 121 a and 122 a of the first electric connection portion 121 and the second electric connection portion 122 is spaced from each other. 20 and 21 (FIGS. 20 and 21). The opposed wall surfaces 121a and 122a are arranged facing each other at an interval so as to be parallel.

  In this counterpart terminal fitting 120, the electric connection portion 11 is inserted between one end portions 121b and 122b (FIGS. 20 and 21) of the first electric connection portion 121 and the second electric connection portion 122, respectively. The electrical connection part 11 is electrically connected. The first electrical connection portion 121 and the second electrical connection portion 122 are provided on one of the opposed wall surfaces 121a and 122a of the one end portions 121b and 122b, respectively, between the first wall surface 11a and the second wall surface 11b of the electrical connection portion 11. One of the first wall surface 11a and the second wall surface 11b is formed and arranged so that one of the first wall surface 11a and the second wall surface 11b is opposed to the other of the opposed wall surfaces 121a and 122a. That is, the first electric connection portion 121 and the second electric connection portion 122 are formed and arranged so that the first wall surface 11a and the second wall surface 11b may be arranged to face either of the opposed wall surfaces 121a and 122a. . In this example, 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 itself is used as a contact point with the electric connection section 11, a contact section (not shown) is provided on each of the first electric connection section 121 and the second electric connection section 122. In this case, the first electrical connection portion 121 is provided with a bulged portion bulged from the facing wall surface 121a of the one end portion 121b toward the facing wall surface 122a of the second electrical connection portion 122 as a contact portion. Then, the second electrical connection portion 122 is provided with a swelling portion bulging from the facing wall surface 122a of the one end portion 122b toward the facing wall surface 121a of the first electrical connection portion 121 as a contact portion. Each of the contact portions has, for example, a spherical surface serving as a contact, and is arranged to be opposed to each other in the direction orthogonal to the respective opposed wall surfaces 121a and 122a with a space therebetween. The interval between the contact portions is made smaller than the plate thickness of the electrical connection portion 11. Therefore, the first electrical connection portion 121 and the second electrical connection portion 122 are connected to the first wall surface 11a and the second wall surface 11b of the electrical connection portion 11 by inserting the electrical connection portion 11 therebetween. Can be contacted. Accordingly, the first electrical connection portion 121 and the second electrical connection portion 122 are physically and electrically connected to the electrical connection portion 11 in the terminal housing chamber 41 of the second housing member 40 of the housing 20. Is done.

  In this counterpart terminal fitting 120, the first electrical connection portion 121 and the second electrical connection portion 122 are connected by the connection portion 123 (FIGS. 20 and 21). The connecting part 123 connects one side end of the other end parts 121c and 122c of the first and second electric connecting parts 121 and 122, respectively.

  Further, the counterpart terminal fitting 120 has a fixed portion 124 fixed to a housing 140 described later (FIGS. 20 and 21). The fixed portion 124 is provided on one of the first electric connection portion 121 and the second electric connection portion 122. The fixed portion 124 in this example is formed in a one-piece shape, and protrudes from an end of the other end portion 122c of the second electric connection portion 122 in the connector insertion / removal direction. Here, the fixed portion 124 protrudes in a direction orthogonal to the facing wall surface 122a of the second electric connection portion 122. 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 electric connection portion 121 and the second electric connection portion 122, respectively. In the present embodiment, this case is taken as an example.

  As the contact member 130, different members may be used for the first electric connection portion 121 and the second electric connection portion 122, respectively, and a common member is used for the first electric connection portion 121 and the second electric connection portion 122. You may. Here, the first electrical connection portion 121 and the second electrical connection portion 122 share the contact member 130.

  The contact member 130 is attached to one end 121b, 122b of each of the first electrical connection 121 and the second electrical connection 122, so that the first electrical connection 121 and the second electrical connection 122 are physically connected to each other. And electrically connected. In other words, the mating terminal 110 includes a combination of the pair of first electrical connection portions 121 and one contact member 130 in contact with each other, and the pair of second electrical connection portions 122 and the other contact member 130 in contact with each other. And a combination. Thereby, the contact member 130 is brought into contact with the first wall surface 11a or the second wall surface 11b of the electric connection portion 11 inserted between the one end portions 121b and 122b of the first and second electric connection portions 121 and 122. be able to. Therefore, the contact member 130 can electrically connect the electric connection part 11 to the first electric connection part 121 and the second electric connection part 122.

  The contact member 130 is formed of a conductive material such as metal (copper, copper alloy, aluminum, aluminum alloy, etc.) so as to have a spring property. 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 electric connection portion 121 and the second electric connection portion 122 are fitted. Therefore, the contact member 130 is formed in an annular or cylindrical shape. For example, the contact member 130 of this example includes two rectangular cylindrical annular portions 131 arranged to face each other with their cylindrical axes aligned and spaced from each other, and four connecting portions connecting the respective annular portions 131. 132 (FIGS. 20 and 21). One end 121b of the first electric connection portion 121 and one end 122b of the second electric connection portion 122 are fitted inside each of the annular portions 131. Each connecting portion 132 is arranged, for example, at each of the corners of the two annular portions 131 and connects the corners facing each other in the cylinder axis direction.

  Furthermore, the contact member 130 has at least one contact portion 133 between each of the annular portions 131 that protrudes outward from each of the annular portions 131 and has elasticity (FIGS. 20 and 21). ). The illustrated contact member 130 has a plurality of contact portions 133 protruding in the same direction with the same amount of protrusion. The contact portion 133 has both ends in the cylinder axis direction connected to the respective annular portions 131, and a curved surface provided at a central maximum projecting position in the cylinder axis direction is a contact point. Each contact portion 133 forms a virtual plane (not shown) by connecting the maximum projecting positions. When the first electric connection portion 121 and the second electric connection portion 122 are fitted, the imaginary plane in this example is opposed to the respective opposing wall surfaces 121a and 122a in a parallel state.

  In the mating connector 101, the first electric connection portion 121 and the second electric connection portion 122 are fitted into the respective contact members 130 such that the virtual planes thereof are arranged parallel to each other and spaced apart from each other. . As a result, the respective contact portions 133 of the respective contact members 130 are arranged to face each other in the direction orthogonal to the respective opposing wall surfaces 121a and 122a of the first electric connection portion 121 and the second electric connection portion 122. The interval between the respective virtual planes is made smaller than the thickness of the electric connection part 11. Therefore, in each of the contact members 130, by inserting the electric connection portion 11 therebetween, the respective contact portions 133 can be brought into contact with the first wall surface 11 a and the second wall surface 11 b of the electric connection portion 11. Therefore, the first electrical connection portion 121 and the second electrical connection portion 122 are physically and individually connected to the electrical connection portion 11 via the contact members 130 in the terminal housing chamber 41 of the second housing 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 above-described contact portion (bulging portion), and the above-described contact portion (bulging portion) may be provided. (Protrusion). In the case of having a contact portion (bulging portion), the mating connector 101 can share the mating terminal fitting 120 regardless of the presence or absence of the contact member 130. Here, the first electrical connection portion 121 and the second electrical connection portion 122 are not provided with contact portions (bulging portions).

  The mating connector 101 includes a housing 140 that houses the mating terminal 110 (FIGS. 1, 18, and 19). The housing 140 includes a housing member 150 (FIGS. 1, 18, and 19) in which the counterpart terminal 110 is housed, and a holding member 160 (FIGS. 18 and 19) that prevents the housed counterpart terminal 110 from falling out of the housing member 150. FIG. 19).

  The housing member 150 is formed of an insulating material such as a synthetic resin. This 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 houses a combination of a pair of second electrical connection portions 122 and the other contact member 130. (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 electric connection portion 122 and the other contact member 130 in a state where the opposed 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 opposed to each other at an interval in a direction orthogonal to the respective opposing wall surfaces 121a and 122a. The interval is set to a size that does not hinder insertion of the electrical connection portion 11 between the respective contact members 130. The housing member 150 is provided with a pair of the first housing body 151 and the second housing body 152 for each counterpart terminal 110.

  The housing member 150 has a cylindrical body 153 in which the connector insertion / removal direction is the cylinder axis direction and both ends in the cylinder axis direction are open (FIGS. 1, 18, and 19). All combinations of the first housing 151 and the second housing 152 extend from the internal space of the cylindrical body 153 in the connector insertion direction, and protrude from the opening 153a at one end of the cylindrical body 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). Further, a holding portion 153d holding the first housing 151 and the second housing 152 and holding the counterpart terminal 110 is provided inside the cylindrical body 153 (FIG. 19). The counterpart terminal 110 is fixed to the holding portion 153d via the male screw member B1 inserted through the through hole 124a. A female screw member N1 to 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 portion 154 outside the cylindrical body 153 for attaching to the housing 201 of the power supply circuit 200 (FIGS. 1, 18 and 19). The flange 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 to which the male screw member B2 is screwed (FIG. 22).

  In the cylindrical body 153, the connector insertion direction side (that is, a portion protruding from the housing 201) of the connector 154 with respect to the flange 154 is a fitting portion (connector fitting) with the connector fitting portion 31 a of the housing 20 of the connector 1. 153e (FIG. 1, FIG. 18, and FIG. 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, a portion of the cylindrical body 153 closer to the connector removal direction than the flange portion 154 (that is, a portion embedded in the housing 201) is 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 a synthetic resin. The holding member 160 is fitted to the fitting portion 153f at the opening 153b at the other end of the cylindrical body 153, and closes the insertion opening 153c of the counterpart terminal 110. The holding member 160 inserts and fits the fitting portion 153f inward. The holding member 160 serves as a fitting portion of the mating connector 101 with the housing 201. 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 and fitted into the mating connector 101 (FIGS. 23 and 24). The connector 1 of the present embodiment is screwed and fixed to the mating connector 101 in order to maintain a fitted state with the mating connector 101 (that is, an electrical connection state with the mating connector 101). In this example, as described above, the connector 1 is fixed to the mating connector 101 side by screwing and fixing the shield shell 20B to the housing 201 in the connector fitted 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 screwing and fixing, or the shield shell 20B is connected to the housing 201 via a conductive screw member. Can be connected electrically. The housing 201 is grounded (earthed).

  The connecting body 53 is formed so as to be screwed and fixed to the housing 201 in a connector fitted state. The connector 53 may be a connector that is brought into contact with the wall surface 201a of the housing 201 in a connector fitted state, or is a member that is floated without making contact with the wall surface 201a of the housing 201 in a connector fitted state. It may be. In this example, the connecting body 53 and the housing 201 are not directly in contact with each other as in the latter case.

  In the connecting body 53, screwing and fixing to the housing 201 is performed between two adjacent sub-shielding bodies 52 arranged in parallel. The male screw portion B0a of the conductive male screw member B0 used for screwing and fixing is arranged between the sub-shields 52. The illustrated connecting body 53 has a fixing portion 53a used for fixing by screwing (FIG. 24). Therefore, the fixing portion 53a is arranged between two adjacent sub-shielding bodies 52 arranged in parallel. The fixing portion 53a is formed with a through hole 54 used for screw fixing (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 has an axis perpendicular to the wall surface 201a of the housing 201. The male screw portion B0a of the male screw member B0 is arranged along the axis between two adjacent sub shield bodies 52 arranged in parallel.

Here, the male screw member B0 may be screwed into a female screw portion formed in the housing 201, or may be a member stood down from the wall surface 201a of the housing 201 like a stud bolt. Is 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 to 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, the 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. As a result, in the shield shell 20B, the head B0b (in the case of using a female screw member, the female screw member) of the male screw member B0 after being screwed and fixed is arranged at a position where it is difficult to see. Therefore, in this connector 1, a person who does not understand the attaching / detaching operation process of the connector 1 to the head B0b (a user of the vehicle or the like) easily inserts a tool and releases the screw fixing. The occurrence of a situation can be suppressed. Such an effect can be obtained similarly 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 it. Thus, in the 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) between two adjacent sub-shielding bodies 52 arranged in parallel. Members) can be arranged without protruding from each sub-shielding body 52. Therefore, in this connector 1, the head B0b protrudes from each sub-shielding body 52, or the head B0b is arranged by screwing and fixing the periphery of the shield shell 20B. The head B0b after screwing and fixing becomes difficult to see. Therefore, in this connector 1, it is possible to enhance the effect of suppressing easy release of the screw fixing by a person who does not understand the attaching / detaching operation process of the connector 1. Such an effect can be obtained similarly even when a female screw member is used.

Furthermore, for example, the fixing portion 53a is configured such that the head B0b (in the case of using a female screw member, the female screw member) of the male screw member B0 has a cylindrical shaft (each of two adjacent sub-shielding bodies 52 arranged in parallel). it is desirable that such be placed on the wall surface 201a side of the housing 201 than the shaft) to form a bearing surface 53a _1. Thus, in the shield shell 20B, the head B0b (female screw) of the male screw member B0 after being screwed and fixed at a position recessed 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 arranged. Therefore, in this connector 1, the head B0b after screwing and fixing is more difficult to visually recognize, and it is possible to more appropriately suppress easy release of screwing and fixing. Such an effect can be obtained similarly even when a female screw member is used.

Furthermore, the seat surface 53a _1, it is desirable to place the most closer to the wall surface 201a of the housing 201 to the extent possible the own formation. Thus, in the shield shell 20B, the head B0b (female) of the male screw member B0 after being screwed and fixed to 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 visually observe, and the easy release of screwing and fixing can be suppressed most. Such an effect can be obtained similarly even when a female screw member is used.

Here, seating surface 53a _1, by causing disposed adjacent the outer peripheral wall 51a of the main shield 51, it is preferable to arranged close to the outer peripheral wall 51a. Thus, in the 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) is connected to two adjacent sub-shielding bodies 52 arranged in parallel. In addition, it is surrounded by the outer peripheral wall 51a of the main shield body 51. Therefore, in the connector 1, the visibility of the head B0b after the screwing and fixing can be further reduced, so that it is possible to further suppress easy release of the screwing and fixing. Such an effect can be obtained similarly 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 the illustrated male screw member B0, a locking member R such as a C-ring is attached to the screw portion B0a side so as to interpose a one-piece fixing portion 53a 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 fixing portion 53a holds the male screw member B0.

In this example, the male screw member B0 is screwed to the female screw portion N0 in a state where the fitting between the connector 1 and the mating connector 101 is completed. Thereby, the connector 1 can maintain the fitted state with the mating connector 101 (the electrical connection state with the mating connector 101), and the first shield member (the shield shell 20B) and the second shield member. 71 can be electrically connected to the housing 201 to exhibit the 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 It is possible to prevent a user or the like from easily releasing the fitted state between the connector 1 and the mating connector 101. Therefore, this connector 1 can suppress the occurrence of such a situation that an unfamiliar user of the vehicle or the like forgets to fix the screws when the connector 1 is mated with the mating connector 101 again, and the shielding performance is improved. Can continue to demonstrate.

  Note that a tool (not shown) such as a socket is inserted into the head B0b of the connecting body 53, and a columnar working space 53b for rotating the head B0b around an axis with the tool is formed. (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 more securely suppress the easy release of screwing and fixing. The insertion of the tool into the screw member) is physically avoided. In order to realize this, the connector 1 moves relative to one of two adjacent sub-shielding bodies 52 arranged in parallel along its own outer peripheral wall 52c between a retracted position and a prevented position. A possible movable member 91 is provided (FIGS. 1 to 5, 13 to 15 and 23 to 29).

  The retracted position is a position where a tool can be inserted into the head B0b (in the case of using a female screw member, a female screw member) of the male screw member B0 after screwing and fixing (FIGS. 1 to 5). , FIGS. 15, 23, 25 and 28). In this connector 1, when the movable member 91 is at the retracted position, a tool is inserted into the head B0b of the male screw member B0 after screwing and fixing, and the screwing state of the male screw member B0 with the female screw portion N0 is changed. Can be canceled. On the other hand, the prevention position is a position at which the tool cannot be inserted into 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) (FIG. 24, 26, 27 and 29). In the connector 1, when the movable member 91 is in the prevention position, the movable member 91 hinders insertion of a tool, so that the tool cannot be inserted into the head B0b of the male screw member B0 after screwing and fixing. However, the screwed state of the male screw member B0 to the female screw portion N0 cannot be released.

  In the connector 1, after the screws are fixed to the housing 201, the movable member 91 is relatively moved to the prevention position. As a result, in the connector 1, the screw fixing to the housing 201 cannot be released unless the movable member 91 is relatively moved to the retracted position. Therefore, if the worker is a person who has grasped the attaching / detaching operation process of the connector 1, the movable member 91 is relatively moved from the prevention position to the retreat position, and the screw fixing of the connector 1 to the housing 201 is performed. Can be canceled. On the other hand, the movable member 91 at the prevention position can make a person who does not understand the attaching / detaching operation process (a user of the vehicle or the like) hesitate to perform, for example, an easy screwing release operation. Therefore, in this connector 1, it is possible to suppress easy release of the screw fixing by a person who does not know the attaching / detaching operation process.

  Specifically, the movable member 91 has a base portion 91a which 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, 13, 14, and 23). And FIGS. 25 to 29). The movable member 91 in this example 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 portion 91a is formed in an arc shape, and is fitted to the outer peripheral wall 52c of the sub shield body 52 concentrically and rotatably.

  Furthermore, the movable member 91 has a cover portion 91b that covers the head B0b (in the case of using a female screw member, the female screw member) of the male screw member B0 after screwing and fixing (FIGS. 1, 4, 5, and 5). 13 to 15, 23 and 25 to 29). The cover portion 91b is arranged at the prevention position on the insertion locus of the tool with respect to the head B0b (in the case of using a female screw member, the female screw member) of the male screw member B0 after screwing and fixing. The cover portion 91b is projected radially outward 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 when in the retracted position, and can be arranged on the tool insertion locus when in the prevention position. Therefore, when the movable member 91 is at the retracted position, the tool can be inserted into the head B0b (in the case of using a female screw member, the female screw member) of the male screw member B0 after screwing and fixing. On the other hand, when the movable member 91 is in the prevention position, the cover portion 91b hinders the insertion of the tool. Therefore, 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). The tool cannot be inserted into the member. In this example, a rectangular piece-shaped cover portion 91b projects radially outward from one end of the base portion 91a in the circumferential direction. In this case, the cover portion 91b is arranged in the above-described cylindrical working space 53b of the tool at the prevention position.

  The movable member 91 makes at least the base portion 91a flexible. For example, the movable member 91 is formed of a synthetic resin or the like.

  Here, the outer peripheral wall 52c of the auxiliary shield body 52 to which the movable member 91 is attached guides the relative rotation of the movable member 91 in the circumferential direction and locks the relative movement of the movable member 91 in the cylinder axis direction. Two guide portions 57 are provided (FIGS. 1, 3, 13 to 15, 23 and 25 to 29). The respective guide portions 57 are arranged facing each other at intervals 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 axial end surface and the outer peripheral surface of 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 axial end surface and the outer peripheral surface of the other end portion. The illustrated guide portion 57 is formed in an L-shape such that it protrudes radially outward from the outer peripheral wall 52c and protrudes from the end on the protruding direction side in the cylinder axis direction of the outer peripheral wall 52c. 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 relatively movably attached to the outer peripheral wall 52c of the sub-shield body 52 to be attached by inserting the respective guide portions 57 into the respective notches 91c. Each of the notches 91c is formed so as to be disposed closer to the prevention position in the circumferential direction than each of the guides 57 when in the retracted position (FIGS. 23 and 26).

Further, between the movable member 91 and the sub-shielding body 52 to which the movable member 91 is attached, there is provided an evacuation holding mechanism M1 for holding the movable member 91 at the evacuation position (FIG. 28). In this drawing, only the shield shell 20B and the movable member 91 are shown for convenience. The evacuation holding mechanism M1 is provided on a protruding portion 91d (FIGS. 14 and 28) protruding radially inward from the inner peripheral surface of the base portion 91a and on 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 (FIG. 28).

  In the connector 1, since the movable member 91 can be held at the evacuation position by the evacuation holding mechanism M1, it is possible to suppress a decrease in workability when the male screw member B0 is screwed.

Further, between the movable member 91 and the sub-shielding body 52 to which the movable member 91 is attached, a prevention holding mechanism M2 for holding the movable member 91 at the prevention position is provided (FIG. 29). In this drawing, only the shield shell 20B and the movable member 91 are shown for convenience. Here, the cylindrical working space 53b of the tool described above partially cuts the outer peripheral wall 52c of the sub-shielding 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 Lock to ₁ . Thereby, the prevention-time holding mechanism M2 can hold the movable member 91 at the prevention position.

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

  In the connector 1, the movable member 91 can be held at the prevention position by the prevention-time holding mechanism M2, so that the cover portion 91b can be continuously arranged on the tool insertion locus at the prevention position. Therefore, the connector 1 can continue to suppress the easy release of the screw fixing by a person who does not understand the attaching / detaching operation process.

  As described above, the connector 1 and the electric wire with connector WH of the present embodiment are in positions where the head B0b (in the case of using a female screw member, the female screw member) of the male screw member B0 after screwing and fixing is difficult to see. , It is possible to prevent a person who does not understand the attaching / detaching operation process of the connector 1 (a user of the vehicle or the like) from easily releasing the screw fixing. Furthermore, the connector 1 and the electric wire WH with a connector of this embodiment cannot insert a tool into the head B0b (in the case of using a female screw member, the female screw member) of the male screw member B0 after screwing and fixing. Since the movable member 91 is provided as described above, also from this point, it is possible to prevent a person who does not understand the attaching / detaching operation process of the connector 1 (a user of the vehicle or the like) from easily releasing the screw fixing. Accordingly, the connector 1 and the electric wire with connector WH of the present embodiment can reduce the chances of such a person inadvertently attaching and detaching from the mating connector 101, so that the screw-fixed state to the housing 201 is maintained. As a result, the desired shield performance can be maintained.

  By the way, in the above-described example, 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, FIGS. 31 and 32 show the retracted position, and FIGS. 33 and 34 show the preventing position. The movable member 92 has a base 92a and a cover 92b similar to the movable member 91.

  The connector 1 includes a holding mechanism M1 at the time of evacuation and a holding mechanism M2 at the time of prevention, 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 protruding portion 58 and a second protruding portion 59 which are opposed to each other at an interval in the cylinder axis direction (FIG. 30 to FIG. 30). 34). Here, the first projecting portion 58 is arranged on the opening 52a side, and the second projecting portion 59 is arranged on the main shield body 51 side, so that the first projecting portion 58 and the second projecting portion 59 can be retracted. The holding mechanism M1 and the prevention-time holding mechanism M2 are configured. Here, 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 is moved to the first projecting portion 58 and the second projecting portion. The insertion position between the first and second portions 59 is defined as a prevention position (FIGS. 33 and 34).

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

  On the other hand, when in the prevention position, the first protrusion 58 and the second protrusion 59 become the prevention holding mechanism M2, and the base of the movable member 92 inserted between the first protrusion 58 and the second protrusion 59. The first protrusion 58 and the second protrusion 59 pinch 92a in the cylinder axis direction.

  As for the movable member 92, at least the base portion 92a has flexibility. Therefore, the movable member 92 can extract the base 92a from between the first protrusion 58 and the second protrusion 59 by bending the cover 92b side of the base 92a outward in the radial direction. it can. Therefore, the movable member 92 can perform relative movement from the prevention position to the retreat position.

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

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