[0057] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments. Furthermore, the constituent elements in the following embodiments include elements that can and are easily substituted by those skilled in the art, or substantially the same elements.

[0058] [Example]

[0059] Figure 1 , Figure 2The connector 1 shown in this embodiment has a square cylindrical portion 17 that fits into the cylindrical portion 91 of the counterpart connector 90. Here, connector 1 is a male connector where the ends of multiple shielded wires W1, W2, W3, and W4 are introduced, and the cylindrical portion 17 serves as the connection point. The counterpart connector 90 is a female connector where the cylindrical portion 91 serves as the connection point. Connector 1 is, for example, assembled into a wiring harness in a vehicle such as an automobile. Here, the wiring harness, for example, for connecting various devices mounted in a vehicle, bundles wiring materials used for power supply and signal communication into a bundle as a collection component, and uses connector 1 or the like to connect the wiring materials to each device. The wiring harness includes, for example, multiple shielded wires W1, W2, W3, and W4; connector 1 for introducing the ends of the multiple shielded wires W1, W2, W3, and W4; and counterpart connector 90 that is electrically and mechanically connected to connector 1. Furthermore, the wiring harness may also include various components such as grommets, protectors, and fasteners.

[0060] like Figure 2 As shown, connector 1 includes a housing 10, a rear cover 20, an upper housing 30, and a lower housing 40. A pair of shielded wires W3 and W4 are introduced into the housing 10 in a direction orthogonal to the extending directions of the pair of shielded wires W1 and W2. Figure 1 and 2 As shown, a pair of shielded wires W1 and W2 are held by shielded wire holding structure 100. A pair of shielded wires W3 and W4 are held by shielded wire holding structure 200. Each shielded wire holding structure 100 and 200 has the same structure. Therefore, the shielded wire holding structure 100 will be described in detail below, and a detailed description of the construction of the shielded wire holding structure 200 will be omitted.

[0061] Furthermore, in the following explanation, the direction in which shielded wires W1 and W2 extend is defined as the extension direction X, the direction in which shielded wires W3 and W4 are arranged orthogonal to the extension direction X is defined as the arrangement direction Y, and the direction in which both the extension direction X and the arrangement direction Y are defined as the height direction Z. Additionally, in the following explanation, one side of the extension direction X will be referred to as side X1, and the other side as side X2. Similarly, side Y1 and side Y2 will be defined for the arrangement direction Y, and side Z1 and side Z2 will be defined for the height direction Z.

[0062] The housing 10 is formed of an insulating resin material. For example... Figure 2As shown, the housing 10 has a housing body 15 and a square cylindrical portion 17 extending from one side (Z2) of the housing body 15 in the height direction Z towards the other side (Z2). Multiple male terminals are provided inside the cylindrical portion 17 of the housing 10. Furthermore, the housing body 15 is formed into a generally rectangular box shape with a length in the height direction Z smaller than that in the extension direction X and the arrangement direction Y. Although not shown, the housing body 15 has an opening on one side (Z1) in the height direction Z. On the housing body 15, on the side (X2) opposite to the extension direction X, wire insertion portions 11 and 12 are provided for inserting the ends of shielded wires W1 and W2. The wire insertion portions 11 and 12 are each formed into a generally cylindrical shape. Additionally, on the side (Y1) of the housing body 15 in the arrangement direction Y, wire insertion portions 13 and 14 are provided for inserting the ends of shielded wires W3 and W4.

[0063] like Figure 3 As shown, a rotation limiting wall portion 18 is provided on the outer peripheral surface of one side Y1 of the wire insertion portion 11, which is disposed on one side Y1 in the arrangement direction Y of the wire insertion portion 11 and 12, protruding to one side Y1. The rotation limiting wall portion 18 has: a first rotation limiting wall portion 18a, which is disposed on the other side X2 with its plate surface facing the extension direction X; a second rotation limiting wall portion 18b, which is disposed on one side X1 with its plate surface facing the extension direction X, and is opposite to the first rotation limiting wall portion 18a in the extension direction X; and a connecting wall 18c, which is disposed with its plate surface facing the arrangement direction Y in a manner that connects the first rotation limiting wall portion 18a and the second rotation limiting wall portion 18b. In other words, the first rotation limiting wall portion 18a and the second rotation limiting wall portion 18b of the rotation limiting protrusion 48 are disposed on the extension direction X side. The portion surrounded by the first rotation limiting wall portion 18a, the second rotation limiting wall portion 18b, and the connecting wall 18c is formed as an opening 18d extending through the height direction Z. Each protruding end of the first rotation limiting wall portion 18a, the second rotation limiting wall portion 18b, and the connecting wall 18c on the other side Z2 of the height direction Z is provided with a conical surface 18e that gradually decreases in cross-sectional area (including the cross-sectional area of ​​the surfaces in the extension direction X and the arrangement direction Y) from the other side Z2 toward one side Z1 in the height direction Z. Furthermore, a reinforcing rib 18f ​​is provided on one side X1 of the second rotation limiting wall portion 18b in the extension direction X, and this reinforcing rib 18f ​​connects the plate surface to the outer periphery of the wire insertion portion 11 with the plate surface facing the height direction Z.

[0064] Here, shielded wires W1 and W2 each have a core portion Wa with a core wire and an insulating sheath Wb disposed around the outer periphery of the core portion Wa. The core portion Wa has a circular cross-section. For example, the core portion Wa is formed by providing a core wire formed by providing a metal wire conductor / twisting and bundling multiple metal wire conductors, and providing an insulating resin layer / inner sheath around the outer periphery of the core wire. Furthermore, a shielding material (not shown) is disposed between the core portion Wa and the sheath Wb. The shielding material suppresses noise from entering the core wire of the core portion Wa. For example, it can be a braided metal wire conductor woven into a mesh and cylindrical shape, or it can be a metal foil (so-called metal foil) formed into a cylindrical shape.

[0065] In addition, shielded terminals WT are provided on shielded wires W1 and W2 respectively. Shielded terminals WT are made of metal, formed into a cylindrical shape, and electrically connected to the shielding material of shielded wires W1 and W2. Furthermore, a sealing element WF1 is provided inside the shielded terminal WT. This sealing element WF1 prevents water from entering the inner circumference of the shielded terminal WT and the outer circumference of each shielded wire W1 and W2, and holds the shielded terminal WT relative to each shielded wire W1 and W2. Additionally, on one side X1 of the extending direction X of the shielded terminal WT, a sealing element WF2 is provided to prevent water from entering the interior of each wire insertion portion 11 and 12, and a metal shielding tube WP is provided for electrically connecting the shielding material of each shielded wire W1 and W2 to the shielded terminal WT.

[0066] Also refer to Figure 3 and Figure 6 Shielded wires W1 and W2 have their core wire portions Wa exposed on one side X1 of the extending direction X of the shielding tube WP, and are inserted into the housing body 15 via wire insertion portions 11 and 12. The core wire portions Wa of each shielded wire W1 and W2 inserted into the housing body 15 are connected to multiple male terminals provided on the cylindrical portion 17 via connecting terminals (not shown). The shielding tube WP and sealing member WF2 of each shielded wire W1 and W2 are housed inside the wire insertion portions 11 and 12. The outer peripheral surface of the sealing member WF2 is in close contact with the inner peripheral surfaces of each wire insertion portion 11 and 12. Here, the outer diameter of the shielding terminal WT is formed to be larger than the outer diameter of the wire insertion portions 11 and 12. Furthermore, the shielding terminal WT is formed into a generally bottomed cylindrical shape, and a flange surface is provided on one side X1 of the extending direction X of the shielding terminal WT. Therefore, the surface WTa of one side X1 of the shielding terminal WT in the extension direction X abuts against the ends 11a and 12a of the other side X2 of the wire insertion parts 11 and 12.

[0067] like Figure 2As shown, the opening (not shown) on one side Z1 of the housing body 15 in the height direction Z of the housing 10 is covered by the rear cover 20 assembled to the housing body 15. The rear cover 20 is formed of an insulating resin material in a generally flat shape. A sealing element 21 is provided between the rear cover 20 and the housing body 15, along the edge of the opening of the housing 10 (see also...). Figure 6 The opening edge of the shell body 15 is sealed with water between the opening edge and the rear cover 20.

[0068] The shielded wire holding structure 100 for holding shielded wires W1 and W2 includes: a first receiving portion 110, a first locking portion 116, and a first fixing portion 117 provided on the holding plate 33 of the upper shell 30; and a second receiving portion 120, a second locking portion 126, and a second fixing portion 127 provided on the lower shell 40. The upper shell 30 and the lower shell 40 will be described in detail below.

[0069] like Figure 2 As shown, the upper shell 30 is formed of a generally shell-shaped material with conductive metal. Specifically, it is provided with a top plate 31 with its surface facing the height direction Z and a peripheral wall 32 extending from the top plate 31 to the other side Z2 in the height direction Z with its surface facing a direction parallel to the arrangement direction Y. A portion of the peripheral wall 32 is intermittently provided around the top plate 31. A retaining plate 33 is provided on the peripheral wall 32 of the upper shell 30 corresponding to the wire insertion portions 11, 12 and 13, 14 of the housing 10, with its surface facing the height direction Z. The upper shell 30 thus formed is assembled to the housing body 15 of the housing 10 in a manner that covers the rear cover 20. The assembly of the upper shell 30 to the housing body 15 is secured by a plurality of bolt through holes 34 provided in the upper shell 30, a plurality of bolts inserted through bolt through holes (not shown) of the housing 10 provided corresponding to the bolt through holes 34, and nuts (not shown) that engage with the bolts.

[0070] like Figure 4 As shown, a first receiving portion 110 is provided on the retaining plate 33 of the upper shell 30 corresponding to the wire insertion portions 11 and 12. The first receiving portion 110 has two semi-cylindrical peripheral wall portions 111, a longitudinal plate 112, and a connecting plate 113. The semi-cylindrical peripheral wall portions 111 of the first receiving portion 110 are formed concavely on the surface Z2 on the other side of the height direction Z of the retaining plate 33, so that the axis (in other words, the axis CL of the shielded wires W1 and W2, see reference) is formed. Figure 6The semi-cylindrical wall portion 111 is open on one side X1 of the extension direction X. A longitudinal plate 112 with its surface facing the extension direction X is provided on the other side X2 of the semi-cylindrical wall portion 111. The longitudinal plate 112 extends from the semi-cylindrical wall portion 111 on one side Y1 of the arrangement direction Y, through a connecting plate 113 (described later), to the semi-cylindrical wall portion 111 on the other side Y2, forming a shape that mimics the approximately semi-cylindrical shape of each semi-cylindrical wall portion 111 and the connecting plate 113. A connecting plate 113 is provided between the two semi-cylindrical wall portions 111. The connecting plate 113 is formed as a flat plate with its surface facing the height direction Z, and is configured to connect adjacent ends of the two approximately semi-cylindrical wall portions 111 to each other (see reference). Figure 7 ).

[0071] The semi-cylindrical peripheral wall portion 111 on one side Y1 of the arrangement direction Y corresponds to the wire insertion portion 11, and the semi-cylindrical peripheral wall portion 111 on the other side Y2 corresponds to the wire insertion portion 12. Each semi-cylindrical peripheral wall portion 111 of the first receiving portion 110 receives a portion of the shielding terminal WT of the shielded wires W1 and W2. Specifically, it receives approximately 1 / 3 of the shielding terminal WT on the side Z1 in the height direction Z (refer to...). Figure 6 and Figure 7 ).

[0072] In addition, such as Figure 4 As shown, on the inner surface (the side of the shielding terminal WT) of the semi-cylindrical peripheral wall portion 111 of the first receiving portion 110, i.e., the peripheral surface 111a, a plurality of first protrusions 115 are provided, which protrude toward the second receiving portion 120 and abut against the shielding terminal WT. The first protrusions 115 are about the axis of the generally semi-cylindrical semi-cylindrical peripheral wall portion 111 of the first receiving portion 110 (in other words, the axis CL of the shielding wires W1 and W2, see reference). Figure 6 There are approximately three of each of the six portions, arranged at roughly equal intervals. The first protrusion 115 is formed as a long, rounded rectangular protrusion that is longer in the extending direction X. In addition, one of the three first protrusions 115 of each semi-cylindrical peripheral wall portion 111 of the first receiving portion 110 is provided at the connection portion between the semi-cylindrical peripheral wall portion 111 and the connecting plate 113.

[0073] like Figure 4As shown, a first locking portion 116 and a first fixing portion 117 are provided on the retaining plate 33 of the upper shell 30, such that they clamp the first receiving portion 110 along the arrangement direction Y. The first locking portion 116 engages with the second locking portion 126, which will be described later. The first locking portion 116 is provided on the retaining plate 33 on the other side Y2 of the first receiving portion 110. Specifically, the first locking portion 116 is formed as a slit that extends through in the height direction Z and is longer in the extension direction X. The first fixing portion 117 is provided on the retaining plate 33 on one side Y1 of the first receiving portion 110. The first fixing portion 117 is formed to accommodate the bolt 108 (see reference). Figure 2 The internal threaded part that engages.

[0074] like Figure 5 As shown, the lower shell 40 is formed of a generally shell-shaped material with conductive metal. The lower shell 40 has a second receiving portion 120. The second receiving portion 120 has two semi-cylindrical peripheral wall portions 121, a longitudinal plate 122, and a connecting portion 123. Each semi-cylindrical peripheral wall portion 121 is formed in a generally semi-cylindrical shape with its axis facing the extending direction X. One side X1 of the semi-cylindrical peripheral wall portion 121 in the extending direction X is open. A longitudinal plate 122 with its plate surface facing the extending direction X is provided on the other side X2 of the semi-cylindrical peripheral wall portion 121 in the extending direction Y. The longitudinal plate 122 extends from the semi-cylindrical peripheral wall portion 121 on one side Y1 of the arrangement direction Y through the connecting portion 123 to the semi-cylindrical peripheral wall portion 121 on the other side Y2, and is formed in a manner that mimics the generally semi-cylindrical shape of each semi-cylindrical peripheral wall portion 121 and the connecting portion 123. On the longitudinal plate 122, two approximately concave arc-shaped cutouts 122a are provided corresponding to the shielded wires W1 and W2 to avoid interference with them. Additionally, the second receiving portion 120 is provided with a connecting portion 123 that connects the ends of adjacent semi-cylindrical peripheral wall portions 121. Each semi-cylindrical peripheral wall portion 121 of the second receiving portion 120 receives another portion of the shielding terminal WT of the shielded wires W1 and W2, specifically, approximately two-thirds of the height of the shielding terminal WT on the other side Z2 in the height direction Z (see reference). Figure 6 and Figure 7 In addition, the semi-cylindrical peripheral wall portion 121 on one side Y1 of the arrangement direction Y corresponds to the wire insertion portion 11, and the semi-cylindrical peripheral wall portion 121 on the other side Y2 corresponds to the wire insertion portion 12.

[0075] On the inner surface (the side of the shielding terminal WT) of each semi-cylindrical peripheral wall portion 121 of the second receiving portion 120, i.e., the peripheral surface 121a, a plurality of second protrusions 125 are provided, protruding toward the first receiving portion 110 and abutting against the shielding terminal WT. The second protrusions 125 are about the axis of each semi-cylindrical peripheral wall portion 121 (in other words, the axis CL of each shielded wire W1, W2, see reference). Figure 6Three are arranged at approximately equal intervals, for a total of six. One of the three second protrusions 125 of each semi-cylindrical peripheral wall portion 121 of the second receiving portion 120 is provided as a second protrusion 125a at the connection between the semi-cylindrical peripheral wall portion 121 and the connecting portion 123. The second protrusion 125a is formed into a generally mountain-shaped form that is longer in the extending direction X, while the other second protrusions 125 are formed into rounded rectangular convex shapes that are longer in the extending direction X.

[0076] In the lower shell 40, a second locking portion 126 and a second fixing portion 127 are provided such that they clamp the second receiving portion 120 along the arrangement direction Y. The second locking portion 126 locks into the first locking portion 116. The second locking portion 126 has a plate-shaped arm 126a extending from the semi-cylindrical peripheral wall portion 121 of the second receiving portion 120 on the other side Y2 of the arrangement direction Y toward one side Z1 and the other side Y2 of the arrangement direction Z. In addition, the second locking portion 126 has a claw portion 126b formed by bending from the arm portion 126a toward the other side Z2 of the height direction Z. The claw portion 126b is formed into a generally flat plate with the plate surface facing the height direction Z. The arm portion 126a and the claw portion 126b are formed to be able to be inserted into the first locking portion 116, which is a slit provided in the upper shell 30. Specifically, as Figures 7-9 As shown, the length of the first locking portion 116 along the extending direction X (i.e., the length of the long side of the first locking portion 116 as a slit) is longer than the length of the arm portion 126a along the extending direction X and the length of the claw portion 126b along the extending direction X (i.e., the width of the second locking portion 126). Furthermore, the length of the first locking portion 116 in the arrangement direction Y is longer than the plate thickness of the second locking portion 126 (arm portion 126a, claw portion 126b).

[0077] return Figure 5 The second locking portion 126 has a protruding ridge 128. The protruding ridge 128 is formed by continuously protruding from the protruding end of the claw portion 126b across the surface 126a1 on the side of the first receiving portion 110 of the arm portion 126a. The protruding ridge 128 is located approximately at the center of the claw portion 126b and the arm portion 126a along the extending direction X. The protruding ridge 128, together with the arm portion 126a and the claw portion 126b, is inserted into the slit (first locking portion 116) (see reference). Figures 7-9 ).

[0078] The second fixing part 127 is provided on one side Y1 of the second receiving part 120 in the Y direction of arrangement. More specifically, the second fixing part 127 is connected to the semi-cylindrical peripheral wall part 121 and the longitudinal plate 122 on the side Y1 of arrangement direction Y, and is provided as a through hole, i.e., a bolt through hole, on the fixing plate 41 with the plate surface facing the height direction Z. In the lower shell 40, a rotation limiting protrusion 48 is provided on one side X1 of the extending direction X of the fixing plate 41 through a cut 42. On the side of the second fixing part 127, the rotation limiting protrusion 48 is formed into a tongue shape near the end of the semi-cylindrical peripheral wall part 121 of the second receiving part 120 on one side Y1 through the cut 42. The end of the tongue-shaped part is bent, thereby protruding towards the side Y1 of arrangement direction Y.

[0079] like Figure 7 As shown, the lower shell 40 is assembled onto the upper shell 30. At this time, the second locking part 126 is locked onto the first locking part 116. Moreover, the bolt 108 is inserted from the other side Z2 in the height direction Z into the second fixing part 127, which is a through hole, and is screwed into the first fixing part 117, which is an internal thread. In this way, the lower shell 40 is fixed relative to the upper shell 30.

[0080] A more detailed explanation of the locking mechanism of the first locking part 116 and the second locking part 126 is provided. For example... Figure 8 As shown, the claw portion 126b inserted into the slit (first locking portion 116) has an abutting portion 126b1 that abuts against the outer edge portion 33a of the outer side of the slit (first locking portion 116) (the other side Y2 of the arrangement direction Y). Both the outer edge portion 33a and the abutting portion 126b1 are flat. The outer edge portion 33a is located on the side opposite to the first receiving portion 110 in the arrangement direction Y, with reference to the slit (first locking portion 116) (see also...). Figure 4 ).

[0081] In addition, such as Figure 8 As shown, the length L3 of the slit (first locking portion 116) along the arrangement direction Y is longer than the length L2 of the abutment portion 126b1 along the arrangement direction Y (L3 > L2), and shorter than the length L1 along the arrangement direction Y from the portion of the first receiving portion 110 side of the arm portion 126a1 closest to the opening edge 116a of the slit (first locking portion 116), i.e., the interference portion 126a2, to the protruding end of the abutment portion 126b1 (L3 < L1).

[0082] like Figure 7As shown, the shielded terminals WT of shielded wires W1 and W2 are held in a manner clamped by a first receiving portion 110 of an upper shell 30 and a second receiving portion 120 of a lower shell 40, which are arranged opposite each other along the height direction Z. In other words, the second receiving portion 120 is arranged opposite to the first receiving portion 110 in a manner capable of clamping the shielded terminal WT. More specifically, the first protrusion 115 of the first receiving portion 110 and the second protrusion 125 of the second receiving portion 120 both abut against the outer periphery of the shielded terminal WT. By engaging the first locking portion 116 with the second locking portion 126 and screwing the bolt 108 through the second fixing portion 127 and into the first fixing portion 117, the first protrusion 115 and the second protrusion 125 press the shielded terminal WT. In this way, the shielded terminal WT is electrically connected to the upper shell 30 and the lower shell 40.

[0083] like Figure 10 As shown, with the lower shell 40 assembled on the upper shell 30, the rotation limiting protrusion 48 of the lower shell 40 is disposed in the inner region of the opening 18d surrounded by the first rotation limiting wall 18a, the second rotation limiting wall 18b and the connecting wall 18c.

[0084] The assembly of the lower shell 40 and the upper shell 30 is as follows: Figure 11 As shown, the second locking portion 126 of the lower shell 40 is oriented towards the side Z1 in the height direction Z, and the claw portion 126b of the lower shell 40 is inserted into the slit (first locking portion 116). After the claw portion 126b is inserted into the slit (first locking portion 116) and hooked onto the opening edge of the slit (first locking portion 116) and locked, the lower shell 40... Figure 12 As shown, the second fixing part 127 of the lower shell 40 is moved laterally to one side Z1 in the height direction Z. Furthermore, while the shielding terminal WT is held by the first receiving part 110 and the second receiving part 120, the bolt 108 is inserted into the through hole of the second fixing part 127 and screwed into the first fixing part 117, which is an internally threaded part. Thus, as... Figure 1 As shown, the lower shell 40 is assembled and fixed to the upper shell 30.

[0085] When the lower shell 40 is assembled to the upper shell 30, the rotation limiting protrusion 48 is inserted into the opening 18d of the rotation limiting wall 18 from the other side Z2 in the height direction Z. At this time, the rotation limiting protrusion 48 is guided by the conical surfaces 18e of the protruding ends of the first rotation limiting wall 18a, the second rotation limiting wall 18b, and the connecting wall 18c.

[0086] In this way, connector 1 holds the shielded wires W1, W2, W3, and W4 whose ends are introduced into housing 10 via shielded wire holding structures 100 and 200, and electrically connects the upper housing 30 and lower housing 40 to the shielded terminals WT of each shielded wire W1, W2, W3, and W4. Therefore, by connecting the upper housing 30 to the vehicle body or the like, connector 1 assembled in the wiring harness can stably establish a grounding connection for the shielded circuit.

[0087] The shielded wire holding structure 100 described above includes: a first receiving portion 110, which is disposed on an upper shell 30 and assembled to a housing 10. The ends of shielded wires W1 and W2, which have shielding material and shielding terminals WT electrically connected to the shielding material, are introduced into the housing 10. The first receiving portion 110 receives a portion of the shielding terminals WT; a second receiving portion 120, which is disposed on a lower shell 40 and assembled to the upper shell 30. The second receiving portion 120 receives another portion of the shielding terminals WT and is disposed opposite to the first receiving portion 110 in a manner that allows the shielding terminals WT to be clamped together with the first receiving portion 110; a first locking portion 116 and a first fixing portion 117. The locking portion 116 and the first fixing portion 117 are disposed on the upper housing 30 such that they sandwich the first receiving portion 110 along an arrangement direction Y intersecting the extending directions X of the shielded wires W1 and W2; and the second locking portion 126 and the second fixing portion 127 are disposed on the lower housing 40 such that they sandwich the second receiving portion 120 along the arrangement direction Y. The second locking portion 126 locks into the first locking portion 116. The first fixing portion 117 has one of an internal thread portion for screwing in a bolt 108 and a through hole for inserting a bolt 108, i.e., an internal thread portion. The second fixing portion 127 has the other of an internal thread portion for screwing in a bolt 108 and a through hole for inserting a bolt 108, i.e., a through hole. Moreover, the connector 1 includes a housing 10, an upper housing 30, and a lower housing 40.

[0088] Therefore, with a simple structure that only engages the first locking portion 116 and the second locking portion 126 and is secured by a single bolt 108, the shielded wires W1 and W2 can be reliably clamped and held using the first receiving portion 110 and the second receiving portion 120. Thus, without the need for multiple bolts for securing, the shielding terminals WT, which are electrically connected to the shielding material of the shielded wires W1 and W2, can be stably electrically connected to the upper housing 30 and the lower housing 40, thereby achieving a suitable structure for holding the shielded wires W1 and W2. Furthermore, since only one bolt 108 is used in a single shielded wire holding structure 100, the number of bolts 108 required is reduced, thereby lowering costs and component management costs.

[0089] Furthermore, the first receiving portion 110 has a first protrusion 115 that protrudes toward the second receiving portion 120 and abuts against the shielding terminal WT, and the second receiving portion 120 has a second protrusion 125 that protrudes toward the first receiving portion 110 and abuts against the shielding terminal WT. As a result, the shielding terminal WT is more reliably electrically connected to the upper housing 30 and the lower housing 40, thus further improving the stability of the shielding circuit connection.

[0090] Furthermore, the first locking portion 116 has a slit that is longer in the extending direction X, and the second locking portion 126 has an arm portion 126a extending from the second receiving portion 120 and a claw portion 126b formed by bending from the arm portion 126a. The arm portion 126a and the claw portion 126b are configured to be inserted into the slit. The claw portion 126b has an abutting portion 126b1 that abuts against the outer edge portion 33a of the slit. The outer edge portion 33a that the abutting portion 126b1 abuts against is located on the side opposite to the first receiving portion 110 in the arrangement direction Y, with the slit as a reference. Thus, the lower shell 40 can be easily assembled to the upper shell 30 by simply hooking the claw portion 126b of the second locking portion 126 onto the first locking portion 116, which serves as the slit.

[0091] Furthermore, the length L3 of the slit of the first locking portion 116 along the arrangement direction Y is longer than the length L2 of the abutment portion 126b1 along the arrangement direction Y, but shorter than the length L1 of the portion along the arrangement direction Y from the part closest to the opening edge 116a of the slit (i.e., the interference portion 126a2) to the protruding end of the abutment portion 126b1 on the surface of the first receiving portion 110 side of the arm portion 126a. Therefore, even if the lower shell 40 is offset to one side Y1 in the arrangement direction Y when the lower shell 40 is assembled to the upper shell 30, the interference portion 126a2 of the arm portion 126a interferes with the opening edge 116a of the slit before the claw portion 126b detaches from the first locking portion 116, thus reducing the possibility of the claw portion 126b detaching from the slit. Additionally, when assembling the lower shell 40 to the upper shell 30, the lower shell 40 can be easily positioned relative to the upper shell 30. Therefore, it is also possible to easily position the second fixing part 127, which serves as the through hole of the bolt 108, and the first fixing part 117, which serves as the internal thread, coaxially. Furthermore, the width dimension of the arm 126a along the extending direction X is close to the length of the slit along the extending direction X (see reference). Figure 9 Therefore, the lower shell 40 is also easy to position in the extension direction X, and the positional offset is reduced.

[0092] Furthermore, the second locking portion 126 has a protruding rib 128 extending from the protruding end of the claw portion 126b to the surface 126a1 of the first receiving portion 110 side of the arm portion 126a. The protruding rib 128 is formed to be able to be inserted into the slit. Thus, the rigidity of the plate-shaped second locking portion 126 can be increased by the protruding rib 128, reducing the gap between the slit and the arm portion 126a (see reference). Figures 7-9 ).

[0093] Furthermore, the lower shell 40 has a rotation-limiting protrusion 48 protruding in the arrangement direction Y on the side of the second fixing part 127, and the housing 10 has a rotation-limiting wall part 18 provided on the side of the extension direction X of the rotation-limiting protrusion 48. Therefore, even if the lower shell 40 attempts to rotate around the axis of the bolt 108 due to the rotational force during the tightening of the bolt 108, the rotation-limiting protrusion 48, which intends to move in the extension direction X, will immediately interfere with the rotation-limiting wall part 18 (specifically, the first rotation-limiting wall part 18a), thus reducing the positional displacement of the lower shell 40 during the tightening of the bolt 108. Additionally, the positional displacement of the lower shell 40 caused by the reaction force of the shielded wires W1 and W2 from the seal WF2 along the extension direction X can also be reduced.

[0094] Furthermore, the shielded wire retention structure and connector of the present invention described above are not limited to the above embodiments, and various modifications can be made within the scope of the claims.

[0095] In the above description, a first fixing part 117 and a second fixing part 127 are provided on one side Y1 of the arrangement direction Y, and a first locking part 116 and a second locking part 126 are provided on the other side Y2, but they can also be arranged in reverse. Furthermore, the first fixing part 117 can be an internal thread portion and the second fixing part 127 a through hole, but the first fixing part 117 can also be a through hole and the second fixing part 127 an internal thread portion. Additionally, the first receiving part 110 and the second receiving part 120 can also be formed to hold one or more shielded wires. Furthermore, in this embodiment, the shielded wire holding structure 100 is provided on the connector 1, but it can also be applied to other electrical devices such as electrical junction boxes where shielded wires are introduced to form a shielded circuit.

[0096] The shielded wire retaining structure and connector of this embodiment can also be constructed by appropriately combining the constituent elements of the embodiments and modifications described above.
