Description

Technical Field

[0001] This disclosure relates to a connector. Background Technology

[0002] Currently, connectors are known for mounting in the housing of electrical equipment mounted in vehicles (see, for example, Patent Document 1). Such connectors have terminal parts that connect to the ends of wires, a connector housing that holds the terminal parts, and a front stop mounted on the connector housing. A spear-shaped member is provided in the connector housing to engage with the terminal parts inserted into it. When the terminal parts are inserted, the spear-shaped member is pressed by the terminal parts and retracts into a flexural space. If the terminal parts are inserted into their proper position, it elastically returns to its original position and engages with the terminal parts. After the terminal parts are inserted into their proper position, the front stop inserts into the flexural space of the spear-shaped member, restricting the spear-shaped member engaged with the terminal parts from retracting into the flexural space. This prevents accidental release of the engagement between the spear-shaped member and the terminal parts, thus preventing the terminal parts from detaching from the connector housing.

[0026] [Description of embodiments of this disclosure]

[0027] First, embodiments of this disclosure will be described.

[0028] [1] The connector disclosed herein has: a connector housing; and a front stop mounted on the connector housing, the front stop being formed in the shape of a flat plate, the front stop having an insertion body portion, a stop portion, a slit disposed between the insertion body portion and the stop portion, and a locking portion disposed on the stop portion and locking with the connector housing, the insertion body portion and the stop portion being arranged in a direction intersecting the insertion direction of the front stop relative to the connector housing.

[0029] According to this structure, since a slit is provided between the insertion body portion and the stop portion of the front stop, the locking portion can move toward the slit when the front stop is inserted into the connector housing. That is, the stop portion with the locking portion can bend toward the slit. Therefore, the front stop can be inserted into the connector housing while the stop portion is bending toward the slit. Thus, compared to the case where the stop portion does not bend, the operating force required to insert the front stop into the connector housing can be reduced. Therefore, the assembly operability of the front stop relative to the connector housing can be improved.

[0030] [2] Preferably, the slit is formed to extend along the insertion direction, and an elongated hole is formed in the stop portion, the elongated hole being longer in the insertion direction than in the arrangement direction of the insertion body portion and the stop portion, and the locking portion is provided on the side of the sidewall constituting the elongated hole.

[0031] According to this structure, since an elongated hole is provided near the locking portion, when the front stop is inserted into the connector housing, the locking portion can move toward the elongated hole. That is, the sidewall of the elongated hole where the locking portion is provided can bend toward the elongated hole. Therefore, when the front stop is inserted into the connector housing, the stop portion can bend toward the slit, and the sidewall constituting the elongated hole can bend toward the elongated hole. Thus, the operating force required to insert the front stop into the connector housing can be further reduced.

[0032] [3] Preferably, the elongated hole is disposed in the stop portion on the side closer to the locking portion in the arrangement direction. According to this structure, since the elongated hole is disposed close to the side closer to the locking portion, the sidewall on which the locking portion is formed can be made thinner. Therefore, the sidewall can be easily flexed toward the elongated hole. Therefore, the operating force when inserting the front stop into the connector housing can be further reduced.

[0033] [4] Preferably, the insertion body has a protrusion that protrudes inward in the insertion direction than the stop portion. According to this structure, since the insertion body is longer than the stop portion, the protrusion of the insertion body can contact the connector housing first, allowing the protrusion to function as a guide. This protrusion guides the insertion of the stop portion relative to the connector housing. Therefore, the assemblability of the stop portion can be improved.

[0034] [5] Preferably, the protrusion has a guide portion that is inclined toward the slit. According to this structure, since the guide portion is provided on the protrusion of the insertion body portion that first contacts the connector housing, when the front stop is inserted into the connector housing, it is guided toward the wall of the connector housing by the guide portion. This improves the ease of assembly of the front stop relative to the connector housing.

[0035] [6] Preferably, the front stop further has a limiting portion connected to the end of the insertion body portion and the stop portion located near the front side of the insertion direction, the limiting portion protruding in an arrangement direction that intersects the insertion body portion and the stop portion and the insertion direction, and the limiting portion contacting the connector housing.

[0036] According to this structure, since the limiting part contacts the connector housing when the front stop is inserted into the connector housing, the insertion amount of the front stop relative to the connector housing is limited. Therefore, the appropriate insertion amount of the front stop can be managed, thus improving the assembly operability of the front stop relative to the connector housing.

[0037] [7] Preferably, the connector housing has a guide groove extending along the insertion direction, and the insertion body has a rib protruding in a direction intersecting the insertion direction and guided by the guide groove. With this structure, the front stop can be inserted into the connector housing while guiding the rib of the insertion body into the guide groove of the connector housing. This improves the ease of assembly of the front stop relative to the connector housing. Furthermore, the rigidity of the insertion body is improved by providing the rib.

[0038] [8] Preferably, it also has a connection terminal held by the connector housing, the connector housing having a storage space and a locking piece configured to elastically deform toward the storage space and lock with the connection terminal, the stop portion being stored in the storage space.

[0039] According to this structure, by housing the stop portion in the storage space, the deflection of the locking piece that locks with the connection terminal toward the storage space is restricted. This prevents the locking between the connection terminal and the locking piece from being released, thus appropriately preventing the connection terminal from detaching from the connector housing.

[0040] [Details of the embodiments disclosed herein]

[0041] Hereinafter, specific examples of the connectors of this disclosure will be described with reference to the accompanying drawings. In the drawings, for ease of explanation, a portion of the structure is sometimes shown exaggeratedly or simplified. Additionally, the dimensional ratios of the parts may differ in different drawings. The terms "parallel" and "orthogonal" in this specification do not refer only to strictly parallel or orthogonal situations, but also to generally parallel or orthogonal situations within the range that achieves the desired effect of this embodiment. Furthermore, the present invention is not limited to the above examples, but refers to the invention as shown in the claims, and includes all modifications with the same meaning and scope as the claims.

[0042] (Overall structure of wire harness 10)

[0043] Figure 1 The wiring harness 10 shown electrically connects two or more electrical devices. For example, the wiring harness 10 electrically connects an inverter 11 located at the front of a vehicle V, such as a hybrid vehicle or electric vehicle, to a high-voltage battery 12 located at the rear of the vehicle V, beyond the inverter 11. The inverter 11 is connected to a wheel drive motor (not shown) that serves as the power source for the vehicle's movement. The inverter 11 generates alternating current from the direct current (DC) of the high-voltage battery 12 and supplies this AC current to the motor. The high-voltage battery 12 is, for example, a battery capable of supplying several hundred volts.

[0044] The wiring harness 10 has multiple (two in this embodiment) wires 20, an outer casing 25 surrounding the multiple wires 20, and a pair of connectors 30 mounted at both ends of the wires 20. One end of the wire 20 is connected to the inverter 11 via the connector 30, and the other end of the wire 20 is connected to the high-voltage battery 12 via the connector 30. The wires 20 are, for example, high-voltage wires capable of handling high voltage and high current. The outer casing 25 protects the internally housed wires 20 from impacts by flying objects and water droplets.

[0045] like Figure 2 As shown, each connector 30 is fixed to the inverter 11 and the high-voltage battery 12 (see reference). Figure 1 The conductive housing 15 of electrical equipment such as connectors 30. Each connector 30, for example, connects to a counterpart terminal 200 (see reference 200) disposed within the housing 15. Figure 5 Electrical connection. The material of the housing 15 can be, for example, iron-based, aluminum-based, or other metallic materials.

[0046] (Structure of shell 15)

[0047] The housing 15 has a box-shaped housing body 16 and an annular mounting portion 17 integrally disposed on the housing body 16 and protruding outward from the housing body 16. The mounting portion 17 is formed into an annular shape through a mounting hole 17X having a through-hole 17X.

[0048] In this specification, "ring" refers to a structure that is seamlessly connected, forming a loop, i.e., a ring-shaped structure with the same starting and ending points. Furthermore, "ring" in this specification includes rings with circular outer edges, rings with elliptical or oblong outer edges, polygonal rings with polygonal outer edges, and rings with rounded polygonal outer edges; it refers to a shape formed by any closed shape whose outer edges are connected by straight lines or curves. A "ring" in top view has a through-hole shape, including cases where the outer edge shape is the same as the inner circumference of the through-hole, and cases where the outer edge shape is different from the inner circumference of the through-hole. A "ring" includes a shape having a predetermined length extending axially along a central axis passing through the center of the through-hole; the length is not limited. Additionally, "ring-shaped" in this specification can be considered as a whole as a ring, including shapes such as a C-shape with cuts, slits, etc., in some parts.

[0049] The mounting hole 17X is formed to communicate between the internal space of the housing body 16 and the external space of the housing body 16. The shape of the mounting hole 17X, for example, when viewed from the through direction, is a flat shape having a long side and a short side. In this specification, "flat shape" includes, for example, a rectangle, an oblong shape, an ellipse, etc. In this specification, "oblong" refers to a shape composed of two parallel lines of approximately equal length and two semicircles. The mounting hole 17X of this embodiment is formed into an oblong shape when viewed from the through direction.

[0050] In addition, in the accompanying drawings, the X-axis represents the front-back direction of connector 30, the Y-axis represents the left-right direction (width direction) of connector 30 orthogonal to the X-axis, and the Z-axis represents the up-down direction (height direction) of connector 30 orthogonal to the XY plane. In the following description, for ease of explanation, the direction extending along the X-axis will be referred to as the front-back direction X, the direction extending along the Y-axis will be referred to as the left-right direction Y, and the direction extending along the Z-axis will be referred to as the up-down direction Z. Furthermore, in the following description, Figure 2 In the diagram, the X arrow is set to forward, and the Z arrow is set to upward.

[0051] The housing 15 has one or more (two in this embodiment) fixing portions 18 for securing the connector 30 to the housing 15. The two fixing portions 18 are provided, for example, on both sides of the assembly portion 17 in the left-right direction Y. Each fixing portion 18 is formed to protrude outwards from the housing body 16. Each fixing portion 18 has a bolt fixing hole 18X extending through it in the up-down direction Z.

[0052] (Structure of connector 30)

[0053] like Figure 3 and Figure 4As shown, the connector 30 has a plurality of connection terminals 40 respectively connected to the ends of a plurality of wires 20, and a connector housing 50 for holding the plurality of connection terminals 40. Figure 4 As shown, the connector 30 has rubber rings 91, 92, and 93 fitted to the outer periphery of the connector housing 50, a front stop 100, a rubber plug 150 fitted to the end of the wire 20, a rear stop 160, and a shield 170 covering the connector housing 50 from the outside.

[0054] (Structure of connecting terminal 40)

[0055] like Figure 5 As shown, each connecting terminal 40 has, for example, a wire connection portion 41 that connects to the end of the wire 20 and a terminal connection portion 42 that connects to the counterpart terminal 200. Each connecting terminal 40 is, for example, a single component formed by connecting the wire connection portion 41 and the terminal connection portion 42 in the front-rear direction X. The material for each connecting terminal 40 can be, for example, metal materials such as copper, copper alloy, aluminum, aluminum alloy, and stainless steel. The connecting terminal 40 can be formed, for example, by stamping a metal sheet with excellent conductivity.

[0056] (Structure of wire connection part 41)

[0057] The wire connection portion 41 is electrically connected to the end of the wire 20. Here, the wire 20 is a sheathed wire having a core wire 21 made of conductor and an insulating sheath portion 22 covering the outer periphery of the core wire 21. The wire connection portion 41 is connected, for example, to the end of the core wire 21 exposed from the insulating sheath portion 22. The wire connection portion 41 is connected to the core wire 21, for example, by crimping, ultrasonic welding, or the like. Thus, the wire connection portion 41 is electrically and mechanically connected to the core wire 21.

[0058] (Structure of terminal connection part 42)

[0059] The terminal connection portion 42 is, for example, formed in a flat plate shape. For example, a through hole 42X for inserting a bolt B1 is formed in the terminal connection portion 42. The through hole 42X extends through the terminal connection portion 42 along the plate thickness direction (here, the vertical direction Z). The terminal connection portion 42 is electrically and mechanically connected to the counterpart terminal 200, for example, by means of the bolt B1. A locking hole 42Y extending through the terminal connection portion 42 along the plate thickness direction is formed in the terminal connection portion 42, for example, between the through hole 42X and the wire connection portion 41.

[0060] (Structure of connector housing 50)

[0061] like Figure 2As shown, the connector housing 50 is, for example, an annular shape extending in the front-rear direction X. The connector housing 50 is, for example, formed into a flat shape that is longer in the left-right direction Y than in the vertical direction Z. The connector housing 50 has an insertion portion 51 that is inserted into a mounting hole 17X of the housing 15 and an outer placement portion 70 disposed on the outside of the housing 15. The insertion portion 51 is inserted (fitted) from the rear to the front in the front-rear direction X relative to the mounting hole 17X. The connector housing 50 is, for example, a single component formed by connecting the insertion portion 51 and the outer placement portion 70 in the axial direction (in this case, the front-rear direction X) of the connector housing 50. As the material of the connector housing 50, insulating materials such as synthetic resin can be used, for example.

[0062] like Figure 4 As shown, the insertion portion 51 is formed, for example, protruding forward from the front end of the outer configuration portion 70. The insertion portion 51 is formed to have a mounting hole 17X (see reference). Figure 2 The inner circumferential surface of the insertion portion 51 is annular, corresponding to the shape of the outer circumferential surface. For example, the insertion portion 51 is formed as a flat shape that is longer in the left-right direction (Y) than in the vertical direction (Z). In this embodiment, the insertion portion 51 is formed as an elongated annular shape.

[0063] (Structure of the insertion part 51)

[0064] like Figure 2 As shown, a receiving groove 51X for receiving a rubber ring 91 is formed on the outer peripheral surface of the insertion portion 51. The receiving groove 51X is formed to be recessed radially inward from the outer peripheral surface of the insertion portion 51. The receiving groove 51X is formed, for example, covering the entire circumferential surface of the outer peripheral surface of the insertion portion 51. A rubber ring 91 is fitted into the receiving groove 51X. The rubber ring 91 seals between the outer peripheral surface of the connector housing 50 and the inner peripheral surface of the housing 15.

[0065] A receiving groove 51Y for receiving a rubber ring 92 is formed on the outer peripheral surface of the insertion portion 51. The receiving groove 51Y is, for example, located rearward than the receiving groove 51X. The receiving groove 51Y is formed to be recessed radially inward from the outer peripheral surface of the insertion portion 51. The receiving groove 51Y is, for example, formed over the entire circumferential surface of the outer peripheral surface of the insertion portion 51. A rubber ring 92 is fitted into the receiving groove 51Y. The rubber ring 92 seals between the outer peripheral surface of the connector housing 50 and the inner peripheral surface of the housing 15.

[0066] (Structure of rubber rings 91 and 92)

[0067] The rubber rings 91 and 92 are configured to be elastically deformable. The rubber rings 91 and 92 are, for example, O-rings. The rubber rings 91 and 92 are, for example, formed as continuous rings covering the entire circumference of the insertion portion 51. In this embodiment, the rubber rings 91 and 92 are formed as elongated rings with both their inner and outer circumferential shapes being oblong.

[0068] (Structure of the insertion part 51)

[0069] like Figure 3 As shown, the insertion portion 51 has, for example, a plurality of (two in this embodiment) retaining holes 52 arranged in the left-right direction Y. Each retaining hole 52 is formed to penetrate the insertion portion 51 in the front-back direction X. A connecting terminal 40 is held inside each retaining hole 52. When viewed from the front-back direction X, the plurality of connecting terminals 40 held inside the retaining holes 52 are arranged at intervals along the long side of the insertion portion 51.

[0070] like Figure 5 As shown, a locking piece 53 is provided inside each retaining hole 52. A receiving space 62 is formed above each locking piece 53. Each receiving space 62 is formed by a gap between the upper surface of the locking piece 53 and the inner peripheral surface of the retaining hole 52. Each receiving space 62 is formed to open forward.

[0071] Each locking piece 53 is configured, for example, to protrude downward from the inner circumferential surface at the rear end of the retaining hole 52 inside the retaining hole 52, and then extend forward in the front-rear direction X inside the retaining hole 52. Each locking piece 53 is configured as a cantilever, with a base end (here, the rear end) connected to the inner circumferential surface of the retaining hole 52 as a fixed end and a top end (here, the front end) located on the side opposite to the base end in the front-rear direction X as a free end. Each locking piece 53 is elastic. Each locking piece 53 is configured to be elastically deformable so that inside the retaining hole 52, the top end of the locking piece 53 is offset in the vertical direction Z relative to the base end of the locking piece 53. Each locking piece 53 is configured, for example, to be able to flex in the vertical direction Z by elastic deformation. Each locking piece 53 is configured, for example, to be able to elastically deform toward the receiving space 62. At the top end of each locking piece 53, a locking protrusion 54 is formed protruding downward from the lower surface of the locking piece 53. The locking protrusion 54 is formed in a direction that intersects with the insertion direction of the connecting terminal 40 (in this embodiment, the front-to-back direction X).

[0072] Each connecting terminal 40 is inserted from the rear side into its corresponding retaining hole 52. For example, the terminal connecting portion 42 of each connecting terminal 40 is inserted into the corresponding retaining hole 52. The terminal connecting portion 42 is disposed, for example, inside the retaining hole 52 below the locking piece 53. The connecting terminal 40 is retained inside the retaining hole 52 by engaging the locking protrusion 54 of the locking piece 53 with the locking hole 42Y of the terminal connecting portion 42. Here, when the connecting terminal 40 is inserted into the retaining hole 52, each locking piece 53 is pressed upward by the terminal connecting portion 42 of the connecting terminal 40 and retracts into the receiving space 62. That is, each locking piece 53 is pressed by the terminal connecting portion 42 during the insertion of the connecting terminal 40 and elastically deforms, bending upward and retracting into the receiving space 62. Afterward, if the connecting terminal 40 is inserted into the correct position, each locking piece 53 elastically returns to its original position and locks into the connecting terminal 40. Specifically, if the locking hole 42Y of the terminal connection part 42 is inserted into the position overlapping with the locking protrusion 54 in the vertical direction Z, the locking piece 53 elastically recovers and the locking protrusion 54 fits into the locking hole 42Y, and the locking protrusion 54 is locked in the locking hole 42Y.

[0073] The front end portion of the terminal connection portion 42, which has a through hole 42X, is formed to protrude further forward than the opening edge of the retaining hole 52. That is, the front end portion of the terminal connection portion 42 protrudes outside the retaining hole 52 (insertion portion 51).

[0074] The insertion portion 51 has a stop member receiving portion 60 for receiving the front stop member 100. The stop member receiving portion 60 is provided, for example, in the retaining hole 52. The stop member receiving portion 60 is also formed, for example, between a plurality of retaining holes 52.

[0075] like Figure 6 and Figure 7 As shown, in this embodiment, the stop member storage portion 60 is formed to extend from one of the two retaining holes 52 to the other. A portion of the stop member storage portion 60 is constituted by a storage space 62. The stop member storage portion 60 is formed to open forward. Figure 4 As shown, the front stop 100 is inserted into the stop receiving portion 60 from the front side along the insertion direction D1. Here, the insertion direction D1 is the insertion direction of the front stop 100 relative to the connector housing 50. In this embodiment, the insertion direction D1 is a direction parallel to the front-rear direction X, and is a direction from the front to the rear in the front-rear direction X.

[0076] (Structure of the stopper storage section 60)

[0077] like Figure 6 As shown, the stop member storage part 60 has a storage part 61 and a storage space 62. The storage part 61 and the storage space 62 are formed to be open to the front.

[0078] like Figure 7As shown, the storage section 61 is disposed, for example, between two locking tabs 53 in the left-right direction Y. The storage section 61 is configured to be held by the two locking tabs 53 in the left-right direction Y. The storage section 61 is formed separately from each storage space 62.

[0079] The storage section 61, for example, has an upper wall 63, a bottom wall 64, a partition wall 65, and an inner wall 66. The storage section 61 is, for example, a space surrounded by the upper wall 63, the bottom wall 64, the partition wall 65, and the inner wall 66. The partition wall 65 is, for example, provided between the upper wall 63 and the bottom wall 64, thus separating the storage section 61 from each storage space 62.

[0080] The upper wall portion 63 is formed to extend in the left-right direction (Y) and the front-back direction (X), for example. A guide groove 63X is formed in the upper wall portion 63. The guide groove 63X is formed to be recessed upward from the lower surface of the upper wall portion 63, for example. The guide groove 63X is provided, for example, at the center of the upper wall portion 63 in the left-right direction (Y). The guide groove 63X extends, for example, in the front-back direction (X).

[0081] The bottom wall portion 64 is formed, for example, opposite to the upper wall portion 63. For example, a guide groove 64X is formed in the bottom wall portion 64. The guide groove 64X is formed, for example, recessed downwards from the upper surface of the bottom wall portion 64. The guide groove 64X is, for example, located at the center of the bottom wall portion 64 in the left-right direction Y. The guide groove 64X extends, for example, in the front-back direction X. The width of the guide groove 64X in the left-right direction Y is, for example, wider than the width of the guide groove 63X in the left-right direction Y.

[0082] In this specification, "opposite" refers to a situation where surfaces or components are positioned face-to-face, including not only situations where they are completely face-to-face but also situations where they are partially face-to-face. Furthermore, "opposite" in this specification includes both situations where a component different from the two parts is sandwiched between the two parts and situations where no component is sandwiched between the two parts.

[0083] The partition wall 65 extends, for example, between the upper wall portion 63 and the bottom wall portion 64. The partition wall 65 extends, for example, in the vertical direction Z. The partition wall 65 is, for example, provided at both ends of the bottom wall portion 64 in the horizontal direction Y. Figure 6 As shown, the partition wall 65 extends, for example, along the insertion direction D1. The partition wall 65 is, for example, located behind the front end face of the connector housing 50. The front end face of the partition wall 65 is, for example, located on the inside side (right side in the figure) of the front end face of the connector housing 50 in the insertion direction D1.

[0084] The inner sidewall portion 66 is provided, for example, between a pair of partition walls 65. The inner sidewall portion 66 is formed to extend in the left-right direction Y and the up-down direction Z, for example. The inner sidewall portion 66 is formed to extend from the partition wall 65 in the left-right direction Y, for example.

[0085] like Figure 7 As shown, each storage space 62 is, for example, a space surrounded by an upper wall 63, a partition wall 65, a side wall 67, and a locking piece 53.

[0086] Sidewall 67 extends, for example, in the vertical direction Z. Sidewall 67 extends downward from the lower surface of upper wall portion 63, for example. Sidewall 67 is positioned, for example, in the horizontal direction Y, outside the locking piece 53. Sidewall 67 is positioned, for example, in the horizontal direction Y, on the side opposite to the partition wall 65, separated by the locking piece 53. Therefore, the locking piece 53 is, for example, sandwiched between sidewall 67 and partition wall 65.

[0087] like Figure 6 As shown, the sidewall 67 extends, for example, along the front-rear direction X. The length of the sidewall 67 in the front-rear direction X is, for example, shorter than the length of the partition wall 65 in the front-rear direction X. The front end face of the sidewall 67 is, for example, located closer to the front side (left side in the figure) in the insertion direction D1 than the front end face of the partition wall 65.

[0088] (Structure of the front stop 100)

[0089] Next, the structure of the front stop 100 will be explained.

[0090] like Figure 8 and Figure 9 As shown, the front stop 100 is formed in the shape of a flat plate. The front stop 100 has an insertion body portion 110, one or more (two in this embodiment) stop portions 120, and a slit 110X provided between the insertion body portion 110 and each stop portion 120. The front stop 100, for example, has a slit provided at each stop portion 120 and connected to the connector housing 50 (see reference 50). Figure 5 The front stop 100 consists of a locking portion 130 that engages and a limiting portion 140 that connects to the insertion body portion 110 and the plurality of stop portions 120. The front stop 100 is, for example, a single component formed integrally with the insertion body portion 110, the stop portion 120, the locking portion 130, and the limiting portion 140. For example, an insulating material such as synthetic resin can be used as the material for the front stop 100.

[0091] The insertion body 110 and two stop portions 120 are arranged, for example, along a direction intersecting the insertion direction D1 (in this case, the left-right direction Y). The insertion body 110 is, for example, located at the center of the front stop member 100 in the left-right direction Y. The two stop portions 120 are, for example, respectively located on both sides of the insertion body 110 in the left-right direction Y. The two stop portions 120 are, for example, configured to clamp the insertion body 110 from both sides in the left-right direction Y. Each stop portion 120 is, for example, separately provided from the insertion body 110 in the left-right direction Y. Each stop portion 120 is separated from the insertion body 110 by a slit 110X provided between the stop portion 120 and the insertion body 110.

[0092] like Figure 6 As shown, in the front stop 100, for example, the insertion body 110 is housed in the housing 61 of the stop housing 60, and the stop 120 is housed in the housing space 62 of the stop housing 60.

[0093] like Figure 8 As shown, the insertion body 110 is formed in a flat plate shape. The insertion body 110 has an upper and lower surface as end faces in the vertical direction Z, a pair of side surfaces as end faces in the horizontal direction Y, and a top surface 111 as end faces in the front-rear direction X. Each stop 120 is formed in a flat plate shape. Each stop 120 has an upper and lower surface as end faces in the vertical direction Z, a pair of side surfaces 121 and 122 as end faces in the horizontal direction Y, and a top surface 123 as end faces in the front-rear direction X. Each side surface of the insertion body 110 is positioned such that, in the horizontal direction Y, it faces the side surface 121 of each stop 120 across a slit 110X. The side surface 122 of each stop 120 is, for example, the outermost end face located in the horizontal direction Y of the front stop 100.

[0094] (Structure of the inserted main body 110)

[0095] The insertion body portion 110 has a predetermined thickness, for example, in the vertical direction Z. The insertion body portion 110 is formed to extend in the horizontal direction Y, for example. The insertion body portion 110 is formed to extend rearward from the limiting portion 140 in the front-rear direction X, for example. The insertion body portion 110 is formed in a cantilever shape, with the base end portion (front end portion) connected to the limiting portion 140 as a fixed end and the top end portion (rear end portion) located on the opposite side of the base end portion in the front-rear direction X as a free end.

[0096] The insertion body 110, for example, has a protrusion 112 that protrudes rearward from the top surface 123 of the stop 120. The protrusion 112 protrudes inward in the insertion direction D1, for example, from the top surface 123 of the stop 120. The protrusion 112, for example, has a guide portion 113 that is inclined toward the slit 110X. The guide portion 113 is formed, for example, on the end face of the protrusion 112 in the left-right direction Y. That is, the guide portion 113 is formed on a portion of the side surface of the insertion body 110. The guide portion 113 is formed, for example, inclined in a manner approaching the adjacent slit 110X from the top surface 111 side of the insertion body 110 toward the restricting portion 140 side. For example, the guide portion 113 is formed inclined in a manner approaching the slit 110X from the inward side (rear side) of the insertion direction D1 toward the near-forward side (front side) of the insertion direction D1. In other words, the guide portion 113 is formed at an angle from the front side of the insertion direction D1 toward the inward side, approaching the center of the protrusion 112 in the left-right direction Y. The protrusion 112 having the guide portion 113 is formed, for example, such that the width dimension in the left-right direction Y decreases as it moves from the top surface 111 side of the protrusion 112 toward the limiting portion 140 side.

[0097] For example, one or more (two in this embodiment) ribs 115 are provided on the upper surface of the insertion body 110. Each rib 115 protrudes upward from the upper surface of the insertion body 110. The two ribs 115 are provided, for example, at the center of the insertion body 110 in the left-right direction Y. The two ribs 115 are provided separately from each other in the left-right direction Y. Each rib 115 extends, for example, along the insertion direction D1. Each rib 115 extends, for example, throughout the entire length of the insertion body 110 in the front-rear direction X. The two ribs 115 are configured, for example, to be... Figure 7 The stop receiving portion 60 shown is guided by the guide groove 63X. The two ribs 115 are configured, for example, to be able to move while in contact with the inner surface of the guide groove 63X.

[0098] like Figure 9 As shown, for example, one or more (two in this embodiment) ribs 116 are provided on the lower surface of the insertion body 110. Each rib 116 protrudes downward from the lower surface of the insertion body 110. The two ribs 116 are provided, for example, in the left-right direction Y, at a position outside the ribs 115. The two ribs 116 are provided, for example, to clamp the two ribs 115 from both sides in the left-right direction Y. The two ribs 116 are provided, for example, in the left-right direction Y, at a position inside the guide portion 113. The two ribs 116 are provided, for example, separately from each other in the left-right direction Y. Each rib 116 extends, for example, along the insertion direction D1. Each rib 116 extends, for example, along the entire length of the insertion body 110 in the front-rear direction X. The two ribs 116 are configured, for example, to be... Figure 7The stop receiving portion 60 shown is guided by the guide groove 64X. The two ribs 116 are configured, for example, to be able to move while in contact with the inner surface of the guide groove 64X.

[0099] (Structure of slit 110X)

[0100] Each slit 110X is provided between the insertion body portion 110 and the corresponding stop portion 120. Each slit 110X is configured to separate the insertion body portion 110 from the corresponding stop portion 120. Each slit 110X is formed to penetrate the front stop member 100 in the vertical direction Z. Each slit 110X extends, for example, along the insertion direction D1. Each slit 110X has a predetermined width, for example, in the arrangement direction (here, the left-right direction Y) where the insertion body portion 110 and the stop portion 120 are arranged. Each slit 110X is longer in the insertion direction D1 than in the left-right direction Y. Each slit 110X opens inward in the insertion direction D1. Each slit 110X extends, for example, from the inward (rear) side of the insertion direction D1 toward the near-front (front) side of the insertion direction D1. Each slit 110X is not formed to extend to the limiting portion 140 in the insertion direction D1. In this embodiment, each slit 110X is formed such that the insertion body 110 and the stop portion 120 are cut from the inside of the insertion direction D1 to the middle of the insertion direction D1. Therefore, in this embodiment, the insertion body 110 and the two stop portions 120 are connected to each other at their base ends, which are the ends near the front side of the insertion direction D1. That is, the front stop member 100 of this embodiment has a connecting portion 118 that connects the base end end of the insertion body 110 to the base end ends of the two stop portions 120.

[0101] like Figure 6 As shown, the partition wall 65 of the stop receiving portion 60 is inserted into the slit 110X. The front end face of the partition wall 65 contacts, for example, the connecting portion 118 of the front stop 100.

[0102] (Structure of stop part 120)

[0103] like Figure 9As shown, each stop portion 120 is formed, for example, to extend in the left-right direction Y. Each stop portion 120 extends rearward from the limiting portion 140 in the front-rear direction X. Each stop portion 120 is formed, for example, to be narrower in the left-right direction Y than the insertion body portion 110. Each stop portion 120 has a predetermined thickness in the vertical direction Z. The thickness of each stop portion 120 in the vertical direction Z is, for example, approximately the same as the thickness of the insertion body portion 110 in the vertical direction Z. The upper surface of each stop portion 120 is formed on the same plane as the upper surface of the insertion body portion 110. The lower surface of each stop portion 120 is formed on the same plane as the lower surface of the insertion body portion 110. Each stop portion 120 is formed in a cantilever shape, with the base end portion (front end portion) connected to the limiting portion 140 as a fixed end and the top end portion (rear end portion) located on the side opposite to the base end portion in the front-rear direction X as a free end.

[0104] For example, one or more (two in this embodiment) ribs 124 are provided on the lower surface of each stop portion 120. Each rib 124 is formed to protrude downward from the lower surface of each stop portion 120. The height of each rib 124 in the vertical direction Z is, for example, lower than the height of each rib 116 in the vertical direction Z. The two ribs 124 are provided at both ends of each stop portion 120 in the horizontal direction Y. That is, the two ribs 124 are formed to extend downward from the side surfaces 121, 122 of each stop portion 120. Each rib 124 extends, for example, along the insertion direction D1. Each rib 124 extends, for example, along the entire length of each stop portion 120 in the front-rear direction X. For example, a recess 120X is formed on the lower surface of each stop portion 120 by means of the two ribs 124.

[0105] like Figure 10 As shown, the lower surface of each stop portion 120 faces, for example, the locking tab 53 of the connector housing 50. For example, the locking tab 53 is inserted into the recess 120X provided on the lower surface of each stop portion 120. For example, the locking tab 53 is inserted between a pair of ribs 124. The width of the recess 120X in the left-right direction Y is, for example, wider than the width of the locking tab 53 in the left-right direction Y.

[0106] like Figure 8As shown, a locking portion 130 is formed on the side surface 122 of each stop portion 120. Each locking portion 130 protrudes outward from the side surface 122 in the left-right direction Y. Each locking portion 130 is, for example, located in the middle portion of the side surface 122 in the front-rear direction X. Each locking portion 130 has, for example, a predetermined width in the vertical direction Z. Each locking portion 130 has, for example, a top surface 131 located on the outermost side in the left-right direction Y, a rear surface 132 serving as the end surface in the front-rear direction X, and a front surface 133. The top surface 131 is, for example, formed to extend parallel to the side surface 122. The rear surface 132 is, for example, formed to be an inclined surface. The rear surface 132 is formed to be inclined such that the amount of protrusion from the side surface 122 increases as it moves from the rear end of the locking portion 130 toward the top surface 131. The front surface 133 is, for example, formed to be an inclined surface. The front end face 133 is formed at an angle, for example, towards the top end face 131 from the front end of the locking portion 130, such that the amount of protrusion from the side face 122 increases. The front end face 133 of the locking portion 130 is, for example, with... Figure 6 The rear end face of the sidewall 67 shown is locked.

[0107] For example, an elongated hole 125 is formed in each stop portion 120. Each elongated hole 125 is formed to penetrate each stop portion 120 in the vertical direction Z. Each elongated hole 125 extends, for example, in the insertion direction D1. Each elongated hole 125 has, for example, a predetermined width in the horizontal direction Y. Each elongated hole 125 is longer in the insertion direction D1 than in the horizontal direction Y. Each elongated hole 125 is formed, for example, to extend in the same direction as the slit 110X (here, the insertion direction D1). For example, each elongated hole 125 is formed to extend parallel to the slit 110X.

[0108] like Figure 9 As shown, each elongated hole 125 is formed, for example, extending from the base end of the corresponding stop portion 120 along the insertion direction D1 to a midpoint in the front-rear direction X of the stop portion 120. Each elongated hole 125 is formed, for example, by a space surrounded by a sidewall 126, a stop portion 120 forming the bottom surface of the recess 120X, and a limiting portion 140. The sidewall 126 is provided at the outermost side in the left-right direction Y of each stop portion 120 and has a side surface 122. The side surface 122 is provided, for example, on the side opposite to the side surface of the sidewall 126 forming the inner surface of the elongated hole 125 in the left-right direction Y. A locking portion 130 is provided on the side surface 122. That is, each locking portion 130 is provided on the side surface 122 of the sidewall 126 forming the elongated hole 125. Here, the side surface 122 forms the outer surface of the elongated hole 125. In other words, each elongated hole 125 is provided near the locking portion 130.

[0109] Each elongated hole 125 is provided, for example, in the left-right direction Y of the stop portion 120 at a position close to one side. Each elongated hole 125 is provided, for example, in the left-right direction Y of the stop portion 120 near the side closer to the locking portion 130. Each elongated hole 125 is provided, for example, near the outer side (side 122 side) of the corresponding stop portion 120 in the left-right direction Y. For example, in each stop portion 120, the distance between the elongated hole 125 and the side 122 is set to be shorter than the distance between the elongated hole 125 and the side 121. The width of each elongated hole 125 in the left-right direction Y is, for example, set to be less than half the width of the stop portion 120 in the left-right direction Y. For example, each elongated hole 125 is provided entirely in a position outside the center of the stop portion 120 in the left-right direction Y (side 122 side).

[0110] Each stop portion 120 is configured, for example, to be able to flex in the left-right direction Y by elastic deformation. Each stop portion 120 is configured, for example, to be able to flex toward the slit 110X. Each stop portion 120 is configured, for example, to be able to flex in a manner that reduces the width of the slit 110X in the left-right direction Y.

[0111] Each sidewall 126 is configured, for example, to be able to flex in the left-right direction Y by elastic deformation. Each sidewall 126 is configured, for example, to be able to flex toward the elongated hole 125. Each sidewall 126 is configured, for example, to be able to flex in a way that reduces the width of the elongated hole 125 in the left-right direction Y.

[0112] (Structure of the limiting part 140)

[0113] The limiting portion 140 is connected, for example, to the base end of the insertion body portion 110 and to the base ends of the two stop portions 120. The limiting portion 140 extends, for example, from one stop portion 120 along the left-right direction Y to the other stop portion 120. The limiting portion 140 extends, for example, from the side surface 122 of one stop portion 120 along the left-right direction Y to the side surface 122 of the other stop portion 120. The limiting portion 140 extends, for example, along the entire length of the front stop member 100 in the left-right direction Y.

[0114] The limiting portion 140 protrudes, for example, in a direction intersecting the insertion direction D1. The limiting portion 140 also protrudes, for example, in a direction intersecting both the direction in which the insertion body portion 110 and the stop portion 120 are arranged (in this case, the left-right direction Y) and the insertion direction D1 (in this case, the front-back direction X) (in this case, the up-down direction Z). The limiting portion 140 protrudes downwards, for example, beyond the lower surface of the insertion body portion 110 and the lower surface of the stop portion 120. The amount by which the limiting portion 140 protrudes from the lower surface of the insertion body portion 110 is, for example, set to be the same as the amount by which the rib 116 protrudes from the lower surface of the insertion body portion 110. Therefore, the lower surface of the limiting portion 140 and the lower surface of the rib 116 are formed on the same plane. Figure 8As shown, the limiting portion 140 protrudes upwards, for example, beyond the upper surface of the insertion body portion 110 and the upper surface of the stop portion 120. The amount by which the limiting portion 140 protrudes from the upper surface of the insertion body portion 110 is, for example, set to be the same as the amount by which the rib 115 protrudes from the upper surface of the insertion body portion 110. Therefore, the upper surface of the limiting portion 140 and the upper surface of the rib 115 are formed on the same plane.

[0115] The limiting portion 140 has, for example, one or more (two in this embodiment) protrusions 141 projecting upward from the upper surface of the limiting portion 140. The two protrusions 141 are provided separately from each other, for example, in the left-right direction Y. Each protrusion 141 extends, for example, in the left-right direction Y. Each protrusion 141 is provided, for example, in the insertion direction D1, at a position overlapping with each slit 110X.

[0116] like Figure 5 As shown, the limiting portion 140 contacts, for example, the connector housing 50. For example, the limiting portion 140 contacts the upper wall portion 63 and the bottom wall portion 64 of the stop member housing portion 60 (see reference). Figure 7 Contact. The limiting part 140 limits the insertion amount of the front stop 100 relative to the connector housing 50 by contacting the connector housing 50.

[0117] (Structure of the outer configuration section 70)

[0118] like Figure 4 As shown, the outer configuration portion 70 is formed, for example, protruding rearward from the rear end of the insertion portion 51. The outer configuration portion 70, when viewed from the front-rear direction X, is an annular shape that is longer in the left-right direction Y than in the vertical direction Z. The outer configuration portion 70 is, for example, formed to be smaller than the outer shape of the insertion portion 51.

[0119] The outer configuration portion 70 has, for example, a plurality of (two in this case) storage holes 71 arranged in the left-right direction Y. Each storage hole 71 is formed to penetrate the outer configuration portion 70 in the front-back direction X. Each storage hole 71 is, for example, in an annular shape extending in the front-back direction X.

[0120] like Figure 5 As shown, each receiving hole 71 communicates with its corresponding holding hole 52. For example, the connection portion between the wire connecting part 41 and the core wire 21 of the wire 20 is received inside each receiving hole 71. For example, the end of the insulation covering part 22 of the wire 20 is received inside the receiving hole 71.

[0121] For example, an annular rubber plug 150 fitted onto the outer peripheral surface of the insulating covering portion 22 is housed at the rear end of each receiving hole 71. The rubber plug 150 seals the outer peripheral surface of the wire 20 with the inner peripheral surface of the receiving hole 71. For example, a rear stop 160 is housed at the rear end of each receiving hole 71. The rear stop 160 is configured to contact the rear end face of the rubber plug 150, for example. The rear stop 160 has a through hole 160X that extends in the front-rear direction X and through which the power supply wire 20 passes.

[0122] A receiving groove 70X for receiving a rubber ring 93 is formed on the outer peripheral surface of the outer mounting portion 70. A pair of receiving protrusions 72 and 73 are formed on the outer peripheral surface of the outer mounting portion 70. Each receiving protrusion 72 and 73 protrudes radially outward from the outer peripheral surface of the outer mounting portion 70. The receiving groove 70X is formed by the pair of receiving protrusions 72 and 73. The receiving groove 70X is formed, for example, covering the entire circumferential surface of the outer peripheral surface of the outer mounting portion 70. A rubber ring 93 is fitted into the receiving groove 70X. The rubber ring 93 seals between the outer peripheral surface of the connector housing 50 and the inner peripheral surface of the shielding housing 170.

[0123] (Structure of rubber ring 93)

[0124] The rubber ring 93 is configured to be elastically deformable. The rubber ring 93 is, for example, an O-ring. The rubber ring 93 is, for example, formed as a continuous ring extending circumferentially throughout the outer outer portion 70. In this embodiment, the rubber ring 93 is formed as an elongated ring with both its inner and outer circumferential shapes being elongated.

[0125] (Structure of the outer configuration section 70)

[0126] like Figure 4 As shown, a pair of locking arms 80 are provided on the outer peripheral surface of the outer configuration portion 70. For example, one locking arm 80 is provided on each of the two sides of the outer configuration portion 70 in the vertical direction Z. Each locking arm 80 is formed, for example, to protrude outward from the outer peripheral surface of the outer configuration portion 70, located behind the receiving protrusion 73 constituting the receiving groove 70X, in the vertical direction Z, and then extends rearward in the front-rear direction X. A locking protrusion 81 is formed at the top end (here, the rear end) of each locking arm 80, protruding to the side opposite to the outer peripheral surface of the outer configuration portion 70. Each locking arm 80 is configured, for example, to be able to flex in the vertical direction Z by elastic deformation.

[0127] (Structure of shielding shell 170)

[0128] The shielding shell 170 has, for example, a covering portion 171 that covers the outer periphery of the outer configuration portion 70 and a fixing portion 172 integrally formed with the covering portion 171. As the material of the shielding shell 170, for example, metal materials such as copper-based or aluminum-based materials can be used.

[0129] (Structure of the covering part 171)

[0130] The covering portion 171 is formed, for example, to surround the outer periphery of the outer arrangement portion 70 throughout the entire circumference. The covering portion 171 is formed, for example, to be annular with an inner circumferential surface having a shape corresponding to the outer circumferential surface of the outer arrangement portion 70. In this embodiment, the covering portion 171 is formed into an elongated annular shape.

[0131] (Structure of fixing part 172)

[0132] The fixing portion 172 is formed, for example, to protrude upward from the front end of the covering portion 171. The width of the fixing portion 172 in the left-right direction Y is wider than the width of the covering portion 171 in the left-right direction Y. At both ends of the fixing portion 172 in the left-right direction Y, a connecting portion 173 protruding forward in the front-back direction X is provided. A fixing hole 173X is formed in each connecting portion 173, which passes through the connecting portion 173 in the vertical direction Z.

[0133] like Figure 5 As shown, the shielding shell 170 is fitted onto the outer side of the outer configuration portion 70 from the rear end side of the connector housing 50. At this time, in the shielding shell 170, the front end face of the covering portion 171 contacts the rear end face of the insertion portion 51 from the rear side, and the rear end face of the covering portion 171 contacts the locking protrusion 81. Thus, the shielding shell 170 is positioned relative to the connector housing 50 in the front-rear direction X. At this time, the covering portion 171 covers the portion between the rear end face of the insertion portion 51 and the locking protrusion 81 in the connector housing 50, i.e., the outer peripheral surface of the outer configuration portion 70.

[0134] Furthermore, the connecting portion 173 of the fixing portion 172 coincides with the fixing portion 18, for example, in such a way that the fixing hole 173X overlaps with the bolt fixing hole 18X of the fixing portion 18 in the vertical direction Z. Moreover, the connecting portion 173 and the fixing portion 18 are fixed by bolts B2 inserted into the fixing hole 173X and the bolt fixing hole 18X. As a result, the shielding shell 170 is fixed to the housing 15, and the shielding shell 170 is electrically connected to the housing 15.

[0135] (Manufacturing method of connector 30)

[0136] Next, the manufacturing method of connector 30 will be described. Here, the method of installing stop 100 before assembling connector housing 50 will be described in detail.

[0137] First, such as Figure 11As shown, a connector housing 50 and a connecting terminal 40 for connection to the end of the wire 20 are prepared. For example, rubber rings 91, 92, and 93 are fitted into the receiving slots 51X, 51Y, and 70X of the connector housing 50, respectively. Additionally, a rubber plug 150 is fitted onto the outer peripheral surface of the end of the insulation covering portion 22 of the wire 20. Next, the connecting terminal 40 for connection to the wire 20 is inserted from the rear into the receiving hole 71 and the retaining hole 52 of the connector housing 50. If the terminal connection portion 42 is inserted into the correct position, the locking protrusion 54 of the locking piece 53 engages with the inner surface of the locking hole 42Y. This prevents the connecting terminal 40 from detaching from the connector housing 50. Furthermore, in this process, the stop member 100 is not received in the stop member receiving portion 60, and the stop portion 120 is not received in the receiving space 62.

[0138] Next, insert the front stop 100 into the stop receiving portion 60 of the connector housing 50 from the front along the insertion direction D1. At this time, as Figure 12 As shown, the insertion body portion 110 of the front stop 100 is formed to be longer in the front-rear direction X compared to the stop portion 120. Therefore, the protrusion 112 of the insertion body portion 110 is inserted into the stop member receiving portion 60 while contacting the connector housing 50 before the stop portion 120. Through this insertion body portion 110, the stop portion 120 can be properly guided into the receiving space 62. In addition, a guide portion 113 inclined towards the slit 110X is formed on the protrusion 112. Since the stop portion 120 is properly guided towards the partition wall 65 of the stop member receiving portion 60 along the slit 110X of the front stop 100 along the guide portion 113, the stop portion 120 can be more properly guided into the receiving space 62. As a result, the assembly workability of the front stop 100 relative to the connector housing 50 can be improved. In addition, two ribs 115 formed on the upper surface of the insertion body portion 110 (see reference) Figure 8 )along Figure 7 The guide groove 63X of the upper wall portion 63 shown is inserted into the inner surface, and two ribs 116 (see reference) are formed on the lower surface of the insertion body portion 110. Figure 9 )along Figure 7 The inner surface of the guide groove 64X of the bottom wall portion 64 shown is inserted. At this time, the front stop 100 can move along the insertion direction D1 while making the two ribs 115 contact the inner surface of the guide groove 63X and the two ribs 116 contact the inner surface of the guide groove 64X.

[0139] Next, the stop portion 120 is inserted into the storage space 62. If the locking portion 130 provided on the stop portion 120 contacts the side wall 67 of the storage space 62, the locking portion 130 is pressed inward in the left-right direction Y from the side wall 67. That is, the pair of locking portions 130 are pressed inward in the direction that the pair of locking portions 130 approach each other from the side wall 67. At this time, a slit 110X is provided in the front stop member 100 to separate each stop portion 120 from the insertion body portion 110. Through this slit 110X, each stop portion 120 is allowed to flex in the left-right direction Y. That is, each stop portion 120 can flex toward the slit 110X. In addition, in the front stop member 100, an elongated hole 125 is formed in each stop portion 120, and a locking portion 130 is formed on the side surface 122 of the side wall 126 constituting the elongated hole 125. This allows the sidewall 126, where the locking portion 130 is formed, to flex in the left-right direction (Y). That is, the sidewall 126 can flex toward the elongated hole 125. Through the flexure of the aforementioned stops 120 and the sidewall 126, the locking portion 130 can be moved appropriately toward the slit 110X. Therefore, compared to the case where the locking portion 130 does not move toward the slit 110X, the operating force when inserting the front stop 100 into the connector housing 50 can be reduced. As a result, the ease of assembly of the front stop 100 with respect to the connector housing 50 can be improved.

[0140] Next, as Figure 6 As shown, if the front stop 100 is inserted into the locking portion 130 at a position rearward of the rear end face of the side wall 67 of the stop receiving portion 60, each stop portion 120 and the side wall 126 elastically recover, and the locking portion 130 is locked onto the rear end face of the side wall 67. This prevents the front stop 100 from falling out of the stop receiving portion 60.

[0141] Next, the effects of this implementation method will be explained.

[0142] (1) Since a slit 110X is provided between the insertion body portion 110 and the stop portion 120 of the front stop 100, when the front stop 100 is inserted into the connector housing 50, the locking portion 130 can move toward the slit 110X. That is, the stop portion 120, where the locking portion 130 is provided, can bend toward the slit 110X. As a result, the front stop 100 can be inserted into the connector housing 50 while the stop portion 120 is bent toward the slit 110X. Therefore, the width of the front stop 100 in the left-right direction Y can be reduced while the front stop 100 is inserted into the connector housing 50. As a result, the operating force when inserting the front stop 100 into the connector housing 50 can be reduced compared to the case where the stop portion 120 does not bend. Therefore, the assembly workability of the front stop 100 relative to the connector housing 50 can be improved.

[0143] (2) The front stop 100 is formed in the shape of a flat plate. Therefore, compared with the case where the front stop 100 is formed in the shape of a box, the front stop 100 can be formed in a small size and the front stop 100 can be made lightweight.

[0144] (3) However, if the thickness of the stop portion 120 is reduced to allow it to flex, warping of the stop portion 120 occurs during its molding. In contrast, in the front stop member 100 of this embodiment, by providing the slit 110X, the stop portion 120 can flex without reducing its thickness. Therefore, the formability of the front stop member 100 can be improved.

[0145] (4) An elongated hole 125, which is longer in the insertion direction D1, is formed in the stop portion 120, and a locking portion 130 is provided on the side 122 of the side wall 126 constituting the elongated hole 125. According to this structure, since the elongated hole 125 is provided near the locking portion 130, when the front stop 100 is inserted into the connector housing 50, the locking portion 130 can move toward the elongated hole 125. That is, the side wall 126 of the elongated hole 125 with the locking portion 130 can bend toward the elongated hole 125. Therefore, when the front stop 100 is inserted into the connector housing 50, the stop portion 120 can bend toward the slit 110X, and the side wall 126 constituting the elongated hole 125 can bend toward the elongated hole 125. Therefore, the operating force required to insert the front stop 100 into the connector housing 50 can be further reduced.

[0146] (5) An elongated hole 125 is provided in the stop portion 120 on the side closer to the locking portion 130 in the left-right direction Y. As a result, the side wall 126 where the locking portion 130 is formed can be made thinner, so the side wall 126 can be easily flexed toward the elongated hole 125. Furthermore, the assembly workability of the front stop member 100 relative to the connector housing 50 can be improved.

[0147] (6) A limiting portion 140 is provided on the front stop 100, protruding in the vertical direction Z intersecting the insertion direction D1 and contacting the connector housing 50. According to this structure, when the front stop 100 is inserted into the connector housing 50, the limiting portion 140 contacts the connector housing 50, thus limiting the insertion amount of the front stop 100 relative to the connector housing 50. Therefore, the appropriate insertion amount of the front stop 100 can be managed, thereby improving the assembly workability of the front stop 100 relative to the connector housing 50.

[0148] (7) In addition, by providing the limiting part 140, the area subjected to the operating force when the front stop 100 is inserted into the connector housing 50 can be increased. Therefore, the assembly workability of the front stop 100 relative to the connector housing 50 can be improved.
