Technical Field

[0001] The present invention relates to a connector. Background Art

[0002] As disclosed in Patent Document 1, a connector is known that includes an inner housing for accommodating a wire with a terminal. This connector also includes an outer housing for accommodating the inner housing and a conductive shielding shell disposed between the inner and outer housings. This connector provides electromagnetic shielding via the shielding shell. Prior art literature Patent Literature

[0003] Patent Document 1: Japanese Patent Application Publication No. 2019-204641 Summary of the Invention Problems to be solved by the invention

[0004] In the aforementioned connector, if the electromagnetic shielding function of the shield shell is not required, the shield shell can be omitted. For connectors that omit the shield shell and connectors that do include a shield shell, sharing the inner and outer shells is advantageous, for example, from the perspective of reducing the number of components. However, when the shield shell is omitted, the gap between the inner and outer shells increases, making it more likely that the inner shell will shift relative to the outer shell. If such inner shell movement occurs at the top end of the inner shell that houses the terminals, for example, it may become difficult to smoothly connect to the mating connector, or the vibration resistance of the connection portion with the mating connector may be reduced.

[0005] An object of the present invention is to provide a connector that can suppress the occurrence of rattling caused by displacement of a top end portion of an inner housing relative to an outer housing, regardless of whether a shield shell is provided or not. Solutions to Problems

[0006] The connector of the present invention comprises: a terminal-carrying wire having a wire and a terminal connected to the wire; an inner shell for accommodating the terminal-carrying wire; an outer shell for accommodating the inner shell; and a shell configuration portion, arranged between the inner shell and the outer shell, capable of configuring a conductive shielding shell, the inner shell and the outer shell respectively having an opening portion, the opening portion enabling the terminal to be connected to a mating terminal, the inner shell having a first top end portion for accommodating the terminal of the terminal-carrying wire, the outer shell having a second top end portion for accommodating the first top end portion, and the connector further comprising a top end portion positioning structure, the top end portion positioning structure positioning the first top end portion relative to the second top end portion. Effects of the Invention

[0007] According to the connector of the present invention, regardless of whether a shield shell is provided or not, occurrence of rattling, in which the distal end portion of the inner housing is displaced relative to the outer housing, can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described below. [1] The connector of the present invention comprises: a terminal-attached wire having a wire and a terminal connected to the wire; an inner shell for accommodating the terminal-attached wire; an outer shell for accommodating the inner shell; and a shell configuration portion, disposed between the inner shell and the outer shell, capable of configuring a conductive shielding shell, the inner shell having a first top portion for accommodating the terminal of the terminal-attached wire, the outer shell having a second top portion for accommodating the first top portion, the first top portion and the second top portion respectively having an opening, the opening enabling the terminal to be connected to a mating terminal, the connector further comprising a top portion positioning structure, the top portion positioning structure positioning the first top portion relative to the second top portion.

[0010] With this structure, by placing the shielding shell in the shell-mounting portion, the connector can be used with improved shielding performance. Furthermore, if the shielding function of the shielding shell is not required, the connector can be used without the shielding shell in the shell-mounting portion. In this case, the top end positioning structure described above allows the first top end of the inner shell to be positioned relative to the second top end of the outer shell.

[0011] [2] In the above [1], the tip portion positioning structure may position the first tip portion relative to the second tip portion by means of a relationship between a recess or a through hole and a protrusion inserted into the recess or the through hole. This structure can easily improve the accuracy of the positioning, for example.

[0012] [3] In the above [1] or [2], each opening may be opened in a direction intersecting the axis of the electric wire. For example, a connector having such an opening can be applied to the above-mentioned top end positioning structure.

[0013] [4] In the above [3], the first top end portion of the inner housing may include a first top end wall, the first top end wall extending so as to intersect the axis of the electric wire and covering the top end of the terminal, the second top end portion of the outer housing may include a second top end wall, the second top end wall being arranged so as to cover the first top end wall, and the top end portion positioning structure may include a structure for positioning the first top end wall relative to the second top end wall. With this structure, for example, by inserting the inner housing into the outer housing along the axis of the electric wire with the terminal, the top end positioning structure can be easily formed.

[0014] [5] In the above [3] or [4], the connector may further include a stopper connecting the terminal, the first top end of the inner housing, and the second top end of the outer housing, and the connector may be configured so that the stopper can be mounted through the opening of the outer housing. With this configuration, for example, it is possible to minimize the need for a through hole in the outer housing or shielding shell for mounting the stopper. This simplifies the structure of the outer housing, or reduces the degradation of shielding performance when the outer housing is used with a shielding shell.

[0015] [6] In any one of the above [1] to [5], it may also be that the inner shell has a first base end portion connected to the first top end portion and accommodating the electric wire, the outer shell has a second base end portion connected to the second top end portion and accommodating the first base end portion, and the connector further has a base end portion positioning structure, the base end portion positioning structure positions the first base end portion relative to the second base end portion, the base end portion positioning structure has at least one of the inner base end side protrusion provided on the first base end portion and the outer base end side protrusion provided on the second base end portion, and the spacing between the first base end portion and the second base end portion is maintained by the base end side protrusion.

[0016] According to this configuration, occurrence of rattling in which the first proximal end portion of the inner housing is displaced relative to the second proximal end portion of the outer housing in a direction intersecting the axis of the electric wire can be further suppressed.

[0017] [7] In the above [6], the base end portion positioning structure may include a plurality of base end side protrusions, and the plurality of base end side protrusions may be arranged at different positions along the circumferential axis of the electric wire. According to this structure, the occurrence of shaking caused by displacement of the first base end portion of the inner housing relative to the second base end portion of the outer housing in a direction intersecting the axis of the electric wire can be further suppressed.

[0018] [Details of Embodiments of the Invention] Specific examples of the connector of the present invention are described below with reference to the accompanying drawings. In each of the drawings, for the sake of convenience, a portion of the structure may be enlarged or simplified. In addition, the dimensional ratios of the various parts may sometimes differ in the various drawings. In addition, the present invention is not limited to these examples, but is presented in the claims, and is intended to include all variations within the meaning and scope equivalent to the claims. "Orthogonal" in this specification includes not only strictly orthogonal situations, but also approximately orthogonal situations within the scope of the effects of the present embodiment.

[0019] (Overall Structure of Connector 10) like Figure 1 As shown, the connector 10 is electrically connected to a mating connector 100 provided on a vehicle-mounted device such as a motor or an inverter. The mating connector 100 includes, for example, two mating terminals and a mating housing that holds the two mating terminals.

[0020] like Figure 1 and Figure 2 As shown, the connector 10 includes two terminal-attached electric wires 20 and a housing 30. Figure 3 As shown, the connector 10 includes a shell placement portion SP where the shield shell 60 can be placed. Figures 4 to 7 The connector 10 is shown without the shield shell 60 .

[0021] like Figures 1 to 3 As shown, the connector 10 has a top end positioning structure 70. Figure 6 and Figure 7 As shown, the connector 10 is provided with a base end positioning structure 80. Figures 1 to 4 As shown, the connector 10 includes a stopper 90 .

[0022] The drawings show mutually orthogonal X, Y, and Z axes. Connector 10 is connected to mating connector 100 along the Y axis. The axis of wire 21 of the two terminal-attached wires 20 is along the Z axis. The two terminal-attached wires 20 are arranged side by side along the X axis.

[0023] (Structure of the terminal-attached electric wire 20) like Figure 2 and Figure 3 As shown, each terminal-attached wire 20 includes a wire 21 and a terminal 22 connected to the wire 21. The wire 21 includes a core wire 21a, a first insulating coating 21b, and a second insulating coating 21c. A braided member (not shown) is disposed between the first insulating coating 21b and the second insulating coating 21c.

[0024] The first insulating coating 21b covers the outer circumference of the core wire 21a. The braided member covers the outer circumference of the first insulating coating 21b. The second insulating coating 21c covers the outer circumference of the braided member. The electric wire 21 is a shielded electric wire. The core wire 21a is, for example, a stranded wire formed by twisting a plurality of metal wires. As the material of the core wire 21a, for example, a copper-based or aluminum-based metal material can be used. The first insulating coating 21b covers the outer circumference of the core wire 21a throughout the entire circumference. As the material of the first insulating coating 21b, for example, a resin material having a polyolefin-based resin such as cross-linked polyethylene or cross-linked polypropylene as a main component, polyvinyl chloride (PVC), etc. can be mentioned. The braided member covers the outer circumference of the first insulating coating 21b throughout the entire circumference. The braided member is formed by braiding conductive wires into a cylindrical shape. As the material of the braided member, for example, a copper-based or aluminum-based metal material can be mentioned.

[0025] The second insulating coating 21c covers the entire outer peripheral surface of the braided member. Examples of the material of the second insulating coating 21c include resin materials containing a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene as a main component.

[0026] The braiding member covers the entire outer circumference of the first insulating coating 21b. The end of the core wire 21a is exposed from the end of the first insulating coating 21b. Furthermore, the electric wire 21 may include, for example, a core wire 21a and an insulating coating covering the outer circumference of the core wire 21a, or may be modified to include no braiding member.

[0027] The terminal 22 is electrically connected to the core wire 21a. The terminal 22 is, for example, in the form of a plate extending in the Z-axis direction. The plate thickness of the terminal 22 is along the X-axis direction. The material of the terminal 22 can be, for example, a copper-based or aluminum-based metal material.

[0028] The terminals 22 are connected to the core wires 21a by, for example, crimping, ultrasonic welding, etc. When the connector 10 is assembled to the mating connector 100, the two terminals 22 of the connector 10 are electrically connected to the two mating terminals of the mating connector 100, respectively.

[0029] (Structure of Housing 30) like Figure 2 and Figure 3 As shown, the housing 30 includes an inner housing 40 and an outer housing 50. The inner housing 40 accommodates the two terminal-attached electric wires 20. The outer housing 50 accommodates the inner housing 40. Examples of materials for the inner housing 40 and the outer housing 50 include insulating resin materials.

[0030] like Figure 2 and Figure 4As shown, the inner housing 40 has two first base end portions 41 arranged side by side along the X axis. The two first base end portions 41 are each cylindrical in shape and house the connection portion between the wire 21 and the terminal 22 of the terminal-attached wire 20 .

[0031] The inner housing 40 has two first distal portions 42 arranged side by side along the X-axis. The first distal portion 42 is connected to the first proximal portion 41. The first distal portion 42 has a first front wall 43 disposed so as to face the mating connector 100. The first front wall 43 has a first opening 43a into which a mating terminal of the mating connector 100 can be inserted. The first opening 43a opens in a direction intersecting the axis of the electrical wire 21. For example, the first opening 43a opens in a direction along the Y-axis.

[0032] like Figure 2 and Figure 5 As shown, the first top portion 42 includes a first rear wall 44 positioned to face the first front wall 43, and two first side walls 45 connecting the side edges of the first front wall 43 and the first rear wall 44. The first top portion 42 includes a first top wall 46 that extends across the axis of the terminal-attached wire 20 to cover the tip of the terminal 22. The first top wall 46 is positioned, for example, to extend along an XY plane perpendicular to the Z axis. The first top wall 46 connects the first front wall 43, the first rear wall 44, and the two first side walls 45.

[0033] like Figure 2 As shown, the outer housing 50 has two second base end portions 51 arranged side by side along the X axis. The two second base end portions 51 are each cylindrical in shape and house the first base end portion 41 of the inner housing 40 .

[0034] The outer housing 50 has two second distal ends 52 arranged side by side along the X-axis. The second distal ends 52 are connected to the second proximal end 51. The second distal end 52 has a second opening 53 that opens to face the mating connector 100. The second opening 53 opens, for example, in a direction along the Y-axis.

[0035] The second top end portion 52 includes a second rear wall 54 disposed facing the second opening 53 and two second side walls 55 forming side edges of the second opening 53 and connected to side edges of the second rear wall 54. Figure 2 、 Figure 3 as well as Figure 5 As shown, the second top end portion 52 includes a second top end wall 56 arranged to cover the first top end wall 46 of the inner housing 40. The second top end wall 56 is connected to the second rear wall 54 and the two second side walls 55.

[0036] (Structure of Shell Arrangement Portion SP and Shield Shell 60) like Figure 3 and Figure 5 As shown, the shell configuration portion SP is provided between the inner shell 40 and the outer shell 50. Figure 2 As shown, the shield case 60 that can be placed in the case placement portion SP has two third base end portions 61 arranged side by side along the X axis. The two third base end portions 61 are each cylindrical in shape and house the first base end portion 41 , respectively.

[0037] The shield shell 60 has two third distal ends 62 arranged side by side in the X-axis direction. The third distal ends 62 are connected to the third base end 61. The third distal end 62 has a third opening 63 that opens to face the mating connector 100. The third opening 63 opens in a direction along the Y-axis, for example.

[0038] The third top portion 62 includes a third rear wall 64 positioned to face the third opening 63, and two third side walls 65 forming the side edges of the third opening 63 and connected to the side edges of the third rear wall 64. The third top portion 62 includes a third top wall 66 positioned to cover the first top wall 46 of the inner housing 40. The third top wall 66 is connected to the third rear wall 64 and the two third side walls 65. Examples of materials for the shielding shell 60 include copper, iron, or aluminum-based metal materials. For example, the third base portion 61 of the shielding shell 60 can be easily configured to cover the inner housing 40 by being configured to divide a surface along the XZ plane into two divided surfaces.

[0039] (Top end positioning structure 70) like Figures 2 to 5 As shown, the top end portion positioning structure 70 positions the first top end portion 42 of the inner housing 40 relative to the second top end portion 52 of the outer housing 50. The top end portion positioning structure 70 positions the first top end portion 42 relative to the second top end portion 52 through the relationship between the recess or through-hole and the protrusion inserted into the recess or through-hole.

[0040] The distal end portion positioning structure 70 includes, for example, a positioning protrusion 71 , and the positioning protrusion 71 is provided so as to protrude outward from the first distal end wall 46 of the first distal end portion 42 . The top end positioning structure 70 includes, for example, a positioning recess 72 provided in the second top end wall 56 of the second top end portion 52 of the outer shell 50. The positioning recess 72 is formed on the inner surface of the second top end wall 56. The positioning protrusion 71 is inserted into the positioning recess 72. Such a positioning recess 72 can also be replaced with a positioning through-hole into which the positioning protrusion 71 is inserted.

[0041] The shape of the positioning projection 71 is preferably a columnar shape such as a polygonal column or a cylindrical column. The shape of the positioning recess 72 can be appropriately changed according to the shape of the positioning projection 71.

[0042] A through hole or a notch may be provided at a position of the shield shell 60 corresponding to the tip portion positioning structure 70 , thereby preventing the shield shell 60 from interfering with the placement of the tip portion positioning structure 70 .

[0043] (Base End Positioning Structure 80) like Figure 2 and Figures 6 to 8 As shown, the proximal end portion positioning structure 80 positions the first proximal end portion 41 of the inner housing 40 relative to the second proximal end portion 51 of the outer housing 50. The proximal end portion positioning structure 80 includes an inner proximal end-side protrusion 81 provided at the first proximal end portion 41 of the inner housing 40. The proximal end portion positioning structure 80 includes an outer proximal end-side protrusion 82 provided at the second proximal end portion 51 of the outer housing 50. The proximal end portion positioning structure 80 maintains the spacing between the first proximal end portion 41 and the second proximal end portion 51 using the inner proximal end-side protrusion 81 and the outer proximal end-side protrusion 82.

[0044] The inner base end side protrusion 81 is composed of a plurality of protrusions arranged at different positions in the circumferential direction along the axis of the electric wire 21, that is, in the circumferential direction of the first base end portion 41. Figure 7 and Figure 8 As shown, the inner proximal end convex portion 81 includes, for example, a first inner proximal end convex portion 81a and a second inner proximal end convex portion 81b that protrude in opposite directions along the X-axis. The inner proximal end convex portion 81 includes, for example, a third inner proximal end convex portion 81c and a fourth inner proximal end convex portion 81d that protrude in opposite directions along the Y-axis.

[0045] The outer proximal end convex portion 82 is composed of a plurality of outer proximal end convex portions 82 arranged at different positions in the circumferential direction along the axis of the electric wire 21, that is, in the circumferential direction of the second proximal end portion 51. The outer proximal end convex portion 82 includes, for example, a first outer proximal end convex portion 82a, a second outer proximal end convex portion 82b, a third outer proximal end convex portion 82c, and a fourth outer proximal end convex portion 82d.

[0046] The first outer proximal end convex portion 82a is configured to abut the first inner proximal end convex portion 81a. The second outer proximal end convex portion 82b is configured to abut the second inner proximal end convex portion 81b. The third outer proximal end convex portion 82c is configured to abut the third inner proximal end convex portion 81c. The fourth outer proximal end convex portion 82d is configured to abut the fourth inner proximal end convex portion 81d.

[0047] A through hole or a notch can be provided at a position of the shield shell 60 corresponding to the proximal end portion positioning structure 80 , thereby preventing the shield shell 60 from interfering with the placement of the proximal end portion positioning structure 80 .

[0048] (Structure of Stopper 90) like Figure 2 、 Figure 4 as well as Figure 5 As shown, the connector 10 of this embodiment includes two stoppers 90 corresponding to the two terminals 22. The connector 10 is configured so that the stoppers 90 can be mounted through the second opening 53 of the outer housing 50.

[0049] Each stopper 90 connects the terminal 22, the first tip 42 of the inner housing 40, and the second tip 52 of the outer housing 50. Each stopper 90 includes two supporting portions 91 and a connecting portion 92 that connects the two supporting portions 91. The two supporting portions 91 are arranged to sandwich the inner housing 40. This allows the terminal 22, the inner housing 40, and the outer housing 50 to be positioned. In other words, each stopper 90 restricts relative movement of the terminal 22, the inner housing 40, and the outer housing 50.

[0050] like Figure 5 As shown, the terminal 22 has a connecting portion insertion recess 22a, and a portion of the connecting portion 92 of the stopper 90 is inserted into the connecting portion insertion recess 22a. By inserting a portion of the connecting portion 92 of the stopper 90 into the connecting portion insertion recess 22a, the movement of the terminal 22 along the Z-axis direction can be restricted.

[0051] like Figure 2 As shown, the inner housing 40 has two grooves 47, and the two supporting portions 91 of the stopper 90 are respectively inserted into the two grooves 47. Each groove 47 is provided so as to extend along the Y-axis direction. By inserting the supporting portions 91 of the stopper 90 into the grooves 47 of the inner housing 40, the movement of the inner housing 40 along the Z-axis direction is restricted.

[0052] like Figure 5 As shown, the second rear wall 54 of the outer housing 50 has two support portion insertion recesses 57, and the top ends of the support portions 91 of the stopper 90 are respectively inserted into the two support portion insertion recesses 57. By inserting the top ends of the support portions 91 into the support portion insertion recesses 57 of the outer housing 50, the stopper 90 is positioned relative to the outer housing 50. Such a stopper 90 is locked to the terminals 22 and the inner housing 40, thereby preventing the terminals 22 and the inner housing 40 from falling out of the outer housing 50.

[0053] (Assembling Method of Connector 10) An example of a method of assembling the connector 10 will be described. To assemble the inner housing 40 to the outer housing 50, the first distal end 42 of the inner housing 40 is inserted from the second proximal end 51 of the outer housing 50. At this time, the positioning projection 71 is inserted into the positioning recess, thereby forming the distal end positioning structure 70. Furthermore, the proximal end positioning structure 80 is formed by arranging the inner proximal end projection 81 so as to face the outer proximal end projection 82.

[0054] After the terminal-attached electric wire 20 is placed in the inner housing 40, the stopper 90 is assembled to the terminal 22, the inner housing 40, and the outer housing 50. At this time, the stopper 90 can be inserted and assembled from the first opening 43a and the second opening 53.

[0055] In the connector 10 , when the function of the shield shell 60 is required, the shield shell 60 can be arranged in the shell arrangement portion SP. The operation of this embodiment will be described.

[0056] In the above-described connector 10, by arranging the shield shell 60 in the shell placement portion SP, the connector 10 can be used as one with improved shielding performance. Alternatively, if the shielding function of the shield shell 60 is not required, the connector 10 can be used without the shield shell 60 in the shell placement portion SP. In this case, the above-described tip portion positioning structure 70 can be used to position the first tip portion 42 of the inner housing 40 relative to the second tip portion 52 of the outer housing 50.

[0057] The effects of this embodiment will be described. (1) The connector 10 includes a terminal-attached wire 20, an inner housing 40, an outer housing 50, and a shell arrangement portion SP. The inner housing 40 includes a first tip portion 42 that accommodates the terminal 22 of the terminal-attached wire 20. The outer housing 50 includes a second tip portion 52 that accommodates the first tip portion 42. The first tip portion 42 includes a first opening 43a that allows the terminal 22 to be connected to a mating terminal. The second tip portion 52 includes a second opening 53 that allows the terminal 22 to be connected to a mating terminal. The connector 10 includes a tip portion positioning structure 70 that positions the first tip portion 42 relative to the second tip portion 52.

[0058] With this structure, as described above, the first tip portion 42 of the inner housing 40 can be positioned relative to the second tip portion 52 of the outer housing 50. Therefore, even when the connector 10 is used without the shield shell 60, the occurrence of playful movement of the first tip portion 42 of the inner housing 40 relative to the second tip portion 52 of the outer housing 50 can be suppressed. In other words, regardless of the presence or absence of the shield shell 60, the occurrence of playful movement of the first tip portion 42 of the inner housing 40 relative to the outer housing 50 can be suppressed.

[0059] The distal end portion positioning structure 70 can suppress the occurrence of rattling in which the first distal end portion 42 of the inner housing 40 is displaced relative to the second distal end portion 52 of the outer housing 50 in a direction intersecting the axis of the electric wire 21 , for example.

[0060] (2) Preferably, the tip portion positioning structure 70 positions the first tip portion 42 relative to the second tip portion 52 by means of the relationship between the recess or through-hole and the protrusion inserted into the recess or through-hole. This structure can easily improve the accuracy of the positioning, thereby more effectively suppressing the occurrence of the aforementioned shaking.

[0061] (3) The first opening 43a of the inner housing 40 and the second opening 53 of the outer housing 50 open in a direction intersecting the axis of the electric wire 21. For example, the aforementioned tip positioning structure 70 can be applied to the connector 10 having such a second opening 53.

[0062] (4) The first top end portion 42 of the inner housing 40 includes a first top end wall 46, which extends so as to intersect the axis of the electric wire 21 and covers the top end of the terminal 22. The second top end portion 52 of the outer housing 50 includes a second top end wall 56, which is arranged so as to cover the first top end wall 46. The top end portion positioning structure 70 has a structure for positioning the first top end wall 46 relative to the second top end wall 56.

[0063] According to this structure, for example, by inserting and assembling the inner housing 40 into the outer housing 50 along the axis of the electric wire 21 , the distal end portion positioning structure 70 can be easily configured.

[0064] (5) As described above, the tip portion positioning structure 70 for positioning the first tip wall 46 relative to the second tip wall 56 is preferably configured as a relationship between a recess or through-hole and a protrusion inserted into the recess or through-hole. In this case, for example, displacement of the inner housing 40 in a direction intersecting the axis of the wire 21 can be appropriately suppressed. Therefore, the aforementioned shaking can be more effectively suppressed.

[0065] (6) The connector 10 includes a stopper 90 that connects the terminal 22, the first distal end 42 of the inner housing 40, and the second distal end 52 of the outer housing 50. The connector 10 is configured so that the stopper 90 can be mounted through the second opening 53 of the outer housing 50. This configuration minimizes the need for, for example, providing a through hole in the outer housing 50 or the shielding shell 60 for mounting the stopper 90. This simplifies the structure of the outer housing 50 and minimizes degradation of shielding performance when used with the shielding shell 60.

[0066] (7) The inner housing 40 has a first base end portion 41, which houses the electric wire 21. The first base end portion 41 is connected to the first distal end portion 42. The outer housing 50 has a second base end portion 51, which houses the first base end portion 41. The second base end portion 51 is connected to the second distal end portion 52. The connector 10 includes a base end portion positioning structure 80, which positions the first base end portion 41 relative to the second base end portion 51. The base end portion positioning structure 80 includes an inner base end side protrusion 81 provided on the first base end portion 41 and an outer base end side protrusion 82 provided on the second base end portion 51. The base end portion positioning structure 80 maintains the interval between the first base end portion 41 and the second base end portion 51 by the inner base end side protrusion 81 and the outer base end side protrusion 82.

[0067] According to this configuration, the base end portion positioning structure 80 can suppress the occurrence of rattling of the first base end portion 41 relative to the second base end portion 51 in a direction intersecting the axis of the wire 21. Therefore, the connector 10 can be suitably used without the shield shell 60.

[0068] (8) The base end portion positioning structure 80 includes a plurality of inner base end side protrusions 81 and a plurality of outer base end side protrusions 82, and the plurality of inner base end side protrusions 81 and the plurality of outer base end side protrusions 82 are arranged at different positions in the circumferential direction along the axis of the electric wire 21. According to this structure, the occurrence of rattling, in which the first base end portion 41 of the inner housing 40 is displaced relative to the second base end portion 51 of the outer housing 50 in a direction intersecting the axis of the electric wire 21, can be further suppressed.

[0069] [Modification] This embodiment can be implemented as follows: This embodiment and the following modifications can be implemented in combination with each other within a range that does not technically conflict.

[0070] The base end portion positioning structure 80 may also be omitted. The proximal end positioning structure 80 may be formed of either the inner proximal end convex portion 81 or the outer proximal end convex portion 82. In this case, the height dimension of the proximal end convex portion may be adjusted appropriately.

[0071] The number of the inner proximal end side convex portion 81 may be single or multiple. The number of the outer proximal end side convex portion 82 may be single or multiple. The stopper 90 may be omitted. In this case, for example, a stopper may be provided that penetrates a wall portion of the outer housing 50 other than the second opening 53. Even with such a stopper, the terminal 22, the first tip portion 42 of the inner housing 40, and the second tip portion 52 of the outer housing 50 can be connected.

[0072] The distal end portion positioning structure 70 may be a structure in which positioning is performed at one location or a structure in which positioning is performed at two or more locations. The distal end positioning structure 70 is not limited to a structure for positioning the first distal end wall 46 relative to the second distal end wall 56. For example, it may also be a structure for positioning the first rear wall 44 relative to the second rear wall 54. Furthermore, the distal end positioning structure 70 may also be a structure for positioning the first side wall 45 relative to the second side wall 55. Furthermore, a plurality of such structures may be combined to form the distal end positioning structure 70.

[0073] In the distal end portion positioning structure 70 , the positioning protrusion 71 may be provided on the second distal end portion 52 of the outer housing 50 , and the positioning recess 72 may be provided on the first distal end portion 42 of the inner housing 40 .

[0074] The top end positioning structure 70 may also be configured to position the first top end 42 relative to the second top end 52 by means of a relationship between a protrusion and a protrusion that abuts the protrusion. For example, the positioning recess 72 of the top end positioning structure 70 may be omitted, and a second positioning protrusion that can abut the side surface of the positioning protrusion 71 may be provided on the second top end wall 56 of the second top end 52 of the outer shell 50. Furthermore, for example, the top end positioning structure 70 may be configured to maintain the spacing between the first top end 42 and the second top end 52 by means of a protrusion, as in the base end positioning structure 80. Even in this case, by positioning the first top end 42 relative to the second top end 52, it is possible to suppress the first top end 42 from shifting relative to the second top end 52.

[0075] That is, the distal end portion positioning structure 70 can also be configured by combining different structures as described above. The first opening 43a and the second opening 53 of the connector 10 described above open in a direction intersecting the axis of the wire 21, but they can also be opened in a direction along the axis of the wire 21. In this modified example, the connector is connected to the mating connector 100 along the axis of the wire 21.

[0076] The number of the terminal-attached electric wires 20 may be one or two or more. ·like Figure 5 As in the non-limiting embodiment shown, the insertion direction of the positioning protrusion 71 relative to the positioning recess 72 or the protruding direction of the positioning protrusion 71 can also be the same as the axis of the wire 21 or the length direction (Z) of the terminal 22, and can be orthogonal to the connection direction (Y) between the connector 10 and the other connector 100.
