Detailed Description

[ description of embodiments of the present disclosure ]

First, embodiments of the present disclosure will be described.

[1] The connector of the present disclosure has: an electric wire; a connection terminal connected to an end of the electric wire; a connector housing holding the connection terminal; an annular rubber plug attached to an outer peripheral surface of the electric wire; a rear stopper mounted to the connector housing and pressing the rubber stopper; and a shield shell covering an outer periphery of the connector housing, wherein the connector housing has a storage space and a locking piece configured to be elastically deformable toward the storage space and to be locked with the shield shell, and the rear stopper has a contact portion stored in the storage space to be in contact with the locking piece.

According to this structure, the contact portion that contacts the locking piece of the connector housing is provided in the rear stopper for preventing the rubber plug attached to the electric wire from coming off. The contact portion is in contact with the locking piece in the storage space, whereby the locking piece is supported by the contact portion, and the locking piece is restrained from being elastically deformed toward the storage space. Therefore, the locking piece and the shielding shell can be prevented from being accidentally released. Further, since the locking piece is supported by the contact portion, buckling of the locking piece can be suppressed even when the locking piece is long, and a decrease in the holding force of the locking piece on the shield case can be suppressed. This can prevent the shield shell from falling off the connector housing.

[2] Preferably, the rear stopper has a stopper portion that presses the rubber stopper and a coupling portion that is coupled to the stopper portion, and the contact portion is a protrusion that protrudes from the coupling portion toward the locking piece. According to this structure, the locking piece is supported by the projection protruding from the coupling portion toward the locking piece. This can suppress elastic deformation of the locking piece toward the storage space.

[3] Preferably, the protrusion is formed to extend in a direction in which the locking piece extends. According to this configuration, since the locking piece can be supported by the projection extending in the direction in which the locking piece extends, buckling of the locking piece can be appropriately suppressed even when the locking piece is lengthened.

[4] Preferably, the coupling portion has a protruding portion protruding in the insertion direction of the rear stopper with respect to the connector housing than the stopper portion in the insertion direction, and the connector housing has a receiving portion for receiving the protruding portion.

According to this structure, the protruding portion provided in the coupling portion is inserted deeper into the connector housing than the stopper portion that presses the rubber stopper. Therefore, even when water pressure is applied to the rubber stopper, for example, the rear stopper can be prevented from tilting in a direction intersecting the insertion direction. This can prevent the rear stopper from falling off the connector housing due to the inclination of the rear stopper.

[5] Preferably, an end surface of the protruding portion in a direction intersecting the insertion direction is in contact with an inner surface of the receiving portion. According to this structure, the end surface of the protruding portion contacts the inner surface of the receiving portion, and the rear stopper can be appropriately prevented from tilting in the direction intersecting the insertion direction. This can appropriately suppress the rear stopper from coming off the connector housing.

[6] Preferably, the connection terminal has a wire connection portion connected to the wire and a terminal connection portion connected to a counterpart terminal, the connector housing has a holding hole for holding the terminal connection portion, a tip end portion of the terminal connection portion protrudes from an opening edge of the holding hole, the terminal connection portion has an opposing surface at least a portion of which opposes the counterpart terminal, and the connector housing has a support portion for supporting the opposing surface of the terminal connection portion, the support portion protruding from the opening edge of the holding hole.

According to this structure, since the facing surface of the terminal connecting portion protruding from the end surface of the holding hole is supported by the supporting portion, the terminal connecting portion can be restrained from being inclined toward the counterpart terminal. Thus, when the connector is inserted into a housing or the like to be connected, the contact between the tip end portion of the terminal connecting portion and the counterpart terminal can be suppressed. Therefore, the insertion operation of the connector can be smoothly performed, and the insertion operation of the connector can be improved.

In this specification, "opposed" refers to a case where the surfaces or members are positioned to face each other, and includes not only a case where the surfaces or members are positioned to face each other entirely but also a case where the surfaces or members are positioned to face each other locally. In addition, "facing" in this specification includes both a case where a member different from two portions is interposed between the two portions and a case where no member is interposed between the two portions.

[7] Preferably, the support portion has a main body portion facing the facing surface of the terminal connection portion, and a rib protruding from the main body portion in a direction in which the main body portion faces the terminal connection portion. According to this structure, the rib is provided in the main body portion, so that the strength of the entire support portion can be improved. Therefore, the terminal connection portion can be appropriately supported by the support portion, and tilting of the terminal connection portion toward the counterpart terminal can be appropriately suppressed.

[8] Preferably, the locking piece is a first locking piece, the connector housing includes a second locking piece provided in the holding hole and locked to the terminal connecting portion, the holding hole includes a bottom wall portion facing the end surface of the terminal connecting portion, the bottom wall portion includes a recess opening at a position facing the second locking piece with the terminal connecting portion interposed therebetween, and the main body portion is formed so as to protrude from an end surface of the bottom wall portion excluding the recess. According to this configuration, since the main body portion is formed only in the bottom wall portion other than the concave portion, the main body portion can be prevented from being enlarged. This can suppress an increase in the resin amount of the connector housing due to the provision of the support portion, and can suppress an increase in the cost of the connector housing.

Specific examples of the connector of the present disclosure are described below with reference to the drawings. In the drawings, a part of the structure is sometimes exaggerated or simplified for convenience of description. In addition, the dimensional ratios of the respective portions may be different in the respective drawings. The terms "parallel" and "orthogonal" in the present specification do not mean only exactly parallel and orthogonal, but also include approximately parallel and orthogonal within a range that can exert the effects of the present embodiment. The present invention is not limited to the above examples, but is defined by the claims, and includes all modifications equivalent to the meanings and the scope of the claims.

The wire harness 10 electrically connects an inverter 11 provided in the front of a vehicle V such as a hybrid vehicle or an electric vehicle, for example, to a high-voltage battery 12 provided at the rear of the vehicle V from the inverter 11. The inverter 11 is connected to a motor (not shown) for driving wheels, which is a power source for driving the vehicle. The inverter 11 generates alternating current from direct current of the high-voltage battery 12, and supplies the alternating current to the motor. The high-voltage battery 12 is, for example, a battery capable of supplying a voltage of several hundred volts.

The wire harness 10 includes a plurality of (two in the present embodiment) electric wires 20, an exterior member 25 that collectively surrounds the plurality of electric wires 20, and a pair of connectors 30 attached to both end portions of the electric wires 20. One end of the electric wire 20 is connected to the inverter 11 via the connector 30, and the other end of the electric wire 20 is connected to the high-voltage battery 12 via the connector 30. The electric wire 20 is, for example, a high-voltage electric wire that can cope with high voltage and high current. The exterior member 25 protects the electric wire 20 housed inside from flying objects and water droplets.

As shown in fig. 2, each connector 30 is fixed to a conductive housing 15 of an electrical device such as the inverter 11 and the high-voltage battery 12 (see fig. 1). Each connector 30 is electrically connected to, for example, a counterpart terminal 200 (see fig. 5) provided in the housing 15. As a material of the case 15, for example, a metal material such as iron-based material or aluminum-based material can be used.

(Structure of housing 15)

The case 15 includes a case body 16 having a box shape, and an annular fitting portion 17 integrally provided to the case body 16 and protruding to the outside of the case body 16. The fitting portion 17 is formed in a ring shape by having a fitting hole 17X penetrating the fitting portion 17.

Here, the term "ring" in the present specification refers to a ring structure in which the whole ring is connected to form a ring without a gap, that is, a ring structure in which the starting point and the ending point coincide. In the present specification, the term "ring" includes a circular ring having a circular outer edge shape, a ring having an elliptical outer edge shape and an oblong outer edge shape, a polygonal ring having a polygonal outer edge shape, and a ring having a rounded polygonal outer edge shape, and refers to a shape formed by arbitrarily closing shapes in which the outer edge shapes are connected by a straight line or a curved line. The "ring" has a shape having a through hole in plan view, and includes a case where the outer edge shape is the same shape as the inner peripheral shape of the through hole and a case where the outer edge shape is a different shape from the inner peripheral shape of the through hole. The "ring" includes a shape having a predetermined length extending in an axial direction extending along a central axis passing through the center of the through hole, and the size of the length is not limited. In the present specification, the whole "annular" may be regarded as a ring, and includes a shape having a cutout, slit, or the like in a part thereof like a C-shape.

The fitting hole 17X is formed to communicate the inner space of the housing main body 16 with the outer space of the housing main body 16. The mounting hole 17X is formed in a flat shape having a long side direction and a short side direction, for example, when viewed from the penetrating direction. In the present specification, "flat shape" includes, for example, a rectangle, an oblong, an oval, and the like. In addition, the "rectangle" in this specification is a shape having long sides and short sides, except for a square shape. In addition, the term "rectangle" in the present specification includes a shape in which the edge portion is chamfered and a shape in which the edge portion is rounded. An "oblong shape" in this specification is a shape composed of two parallel lines of approximately equal length and two semicircular shapes. The mounting hole 17X of the present embodiment is formed in an oblong shape when viewed from the penetrating direction.

In each drawing, the X-axis of the XYZ axes represents the front-back direction of the connector 30, the Y-axis represents the left-right direction (width direction) of the connector 30 orthogonal to the X-axis, and the Z-axis represents the up-down direction (height direction) of the connector 30 orthogonal to the XY plane. In the following description, for convenience of explanation, a direction extending along the X axis is referred to as a front-rear direction X, a direction extending along the Y axis is referred to as a left-right direction Y, and a direction extending along the Z axis is referred to as an up-down direction Z. In the following description, the X arrow direction in fig. 2 is set to the front, and the Z arrow direction is set to the upper.

The housing 15 has one or more (two in the present embodiment) fixing portions 18 for fixing the connector 30 to the housing 15. The two fixing portions 18 are provided on both sides of the fitting portion 17 in the left-right direction Y, for example. Each of the fixing portions 18 is formed to protrude outside the housing main body 16, for example. Each fixing portion 18 has a bolt fixing hole 18X penetrating the fixing portion 18 in the up-down direction Z.

(Structure of connector 30)

As shown in fig. 3 and 4, the connector 30 includes a plurality of connection terminals 40 connected to the ends of the plurality of electric wires 20, respectively, and a connector housing 50 holding the plurality of connection terminals 40. As shown in fig. 4, the connector 30 has rubber rings 91, 92, 93 fitted to the outer periphery of the connector housing 50, a front stopper 100, a rubber stopper 110 made of rubber fitted to the end of the electric wire 20, a rear stopper 120, and a shield shell 170 covering the connector housing 50 from the outside.

(Structure of connection terminal 40)

As shown in fig. 5, each connection terminal 40 has, for example, an electric wire connection portion 41 connected to an end portion of the electric wire 20 and a terminal connection portion 42 connected to the counterpart terminal 200. Each connection terminal 40 is, for example, a single component in which the wire connection portion 41 and the terminal connection portion 42 are connected in the front-rear direction X and are integrally formed. As a material of each connection terminal 40, for example, a metal material such as copper, copper alloy, aluminum alloy, or stainless steel is used. The connection terminal 40 can be formed by, for example, press working a metal plate having excellent conductivity.

(Structure of wire connecting portion 41)

The wire connection portion 41 is electrically connected to an end of the wire 20. The electric wire 20 is a covered electric wire having a core wire 21 made of a conductor and an insulating covering 22 covering the outer periphery of the core wire 21. The wire connection portion 41 is connected to, for example, an end portion of the core wire 21 exposed from the insulating coating portion 22. The wire connection portion 41 is connected to the core wire 21 by, for example, crimping, ultrasonic welding, or the like. Thereby, the wire connection portion 41 is electrically and mechanically connected to the core wire 21.

(Structure of terminal connecting portion 42)

The terminal connection portion 42 is formed in a flat plate shape, for example. For example, a through hole 42X into which the bolt B1 is inserted is formed in the terminal connection portion 42. The through hole 42X is formed to penetrate the terminal connection portion 42 in the plate thickness direction (here, the up-down direction Z). The terminal connection portion 42 is electrically and mechanically connected to the counterpart terminal 200 by, for example, a bolt B1. The terminal connecting portion 42 has an opposing surface 42A (herein, a lower surface) at least a portion of which opposes the counterpart terminal 200. In the terminal connection portion 42, for example, between the through hole 42X and the wire connection portion 41, a locking hole 42Y penetrating the terminal connection portion 42 in the plate thickness direction is formed.

(Structure of connector housing 50)

As shown in fig. 2, the connector housing 50 has, for example, a ring shape extending in the front-rear direction X. The connector housing 50 is formed in a flat shape longer in the left-right direction Y than in the up-down direction Z, for example. The connector housing 50 has an insertion portion 51 to be inserted into the fitting hole 17X of the housing 15 and an outer arrangement portion 70 arranged outside the housing 15. The insertion portion 51 is inserted (fitted) into the fitting hole 17X from the rear side toward the front side in the front-rear direction X. The connector housing 50 is, for example, a single component in which the insertion portion 51 and the outer arrangement portion 70 are integrally connected to each other in the axial direction (in this case, the front-rear direction X) of the connector housing 50. As a material of the connector housing 50, for example, an insulating material such as a synthetic resin is used.

As shown in fig. 4, the insertion portion 51 is formed so as to protrude forward from the front end of the outer placement portion 70, for example. The insertion portion 51 is formed in a ring shape having an outer peripheral surface with a shape corresponding to an inner peripheral surface of the fitting hole 17X (see fig. 2). The insertion portion 51 is formed in a flat shape longer in the left-right direction Y than in the up-down direction Z, for example. The insertion portion 51 of the present embodiment is formed in an oblong shape.

(Structure of insertion portion 51)

As shown in fig. 2, a receiving groove 51X for receiving the rubber ring 91 is formed in the outer peripheral surface of the insertion portion 51. The receiving groove 51X is formed to be recessed from the outer peripheral surface of the insertion portion 51 toward the radial inner side of the insertion portion 51. The storage groove 51X is formed, for example, over the entire circumference of the outer peripheral surface of the insertion portion 51. A rubber ring 91 is fitted in 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 shell 15.

A receiving groove 51Y for receiving the rubber ring 92 is formed in the outer peripheral surface of the insertion portion 51. The storage groove 51Y is provided, for example, at a position rearward of the storage groove 51X. The receiving groove 51Y is formed to be recessed from the outer peripheral surface of the insertion portion 51 toward the radial inner side of the insertion portion 51. The storage groove 51Y is formed, for example, over the entire circumference of the outer peripheral surface of the insertion portion 51. A rubber ring 92 is fitted in 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 shell 15.

(Structure of rubber rings 91, 92)

The rubber rings 91 and 92 are elastically deformable. The rubber rings 91, 92 are, for example, O-rings. The rubber rings 91 and 92 are formed, for example, in a ring shape that is continuous throughout the entire circumference of the insertion portion 51. The rubber rings 91 and 92 of the present embodiment are formed in a doughnut shape having an inner peripheral shape and an outer peripheral shape.

(Structure of insertion portion 51)

As shown in fig. 3, the insertion portion 51 has a plurality of (two in the present embodiment) holding holes 52 arranged in the left-right direction Y, for example. Each holding hole 52 is formed to penetrate the insertion portion 51 in the front-rear direction X. The connection terminals 40 are held in the holding holes 52. The plurality of connection terminals 40 held in the holding hole 52 are arranged at intervals in the longitudinal direction of the insertion portion 51 when viewed in the front-rear direction X.

As shown in fig. 5, a locking piece 53 is provided inside each holding hole 52. A storage space 62 is formed above each locking piece 53. Each of the storage spaces 62 is formed by a gap formed between the upper surface of the locking piece 53 and the inner peripheral surface of the holding hole 52. Each of the storage spaces 62 is formed to be opened forward.

The locking pieces 53 are formed so as to extend forward in the front-rear direction X in the holding hole 52 after protruding downward from the inner peripheral surface at the rear end portion of the holding hole 52 in the holding hole 52. Each of the locking pieces 53 is formed in a cantilever shape having a base end portion (here, a rear end portion) connected to the inner peripheral surface of the delimiting and holding hole 52 as a fixed end and a tip end portion (here, a front end portion) located on the opposite side of the base end portion in the front-rear direction X as a free end. Each of the locking pieces 53 has elasticity. Each of the locking pieces 53 is elastically deformable so that the tip end portions of the locking pieces 53 are displaced in the up-down direction Z from the base end portions of the locking pieces 53 in the holding hole 52. Each of the locking pieces 53 is configured to be deflectable in the up-down direction Z by elastic deformation, for example. Each of the locking pieces 53 is configured to be elastically deformable toward the storage space 62, for example. A locking protrusion 54 protruding downward from the lower surface of each locking piece 53 is formed at the distal end of each locking piece 53.

Each connection terminal 40 is inserted into the corresponding holding hole 52 from the rear side. For example, the terminal connection portion 42 of each connection terminal 40 is inserted into the corresponding holding hole 52. The terminal connecting portion 42 is disposed below the locking piece 53, for example, in the holding hole 52. The connection terminal 40 is held in the holding hole 52 by, for example, fitting the locking convex portion 54 of the locking piece 53 into the locking hole 42Y of the terminal connection portion 42. Here, when the connection terminal 40 is inserted into the holding hole 52, each locking piece 53 is pushed upward by the terminal connection portion 42 of the connection terminal 40 and retreats toward the storage space 62. That is, each locking piece 53 is pressed by the terminal connecting portion 42 at the time of insertion of the connecting terminal 40, elastically deformed, and deflected upward, and retracted into the housing space 62. After that, when the connection terminal 40 is inserted into the normal position, the locking pieces 53 are elastically restored to be locked to the connection terminal 40. Specifically, when the locking hole 42Y of the terminal connecting portion 42 is inserted to a position overlapping the locking protrusion 54 in the up-down direction Z, the locking piece 53 is elastically restored, the locking protrusion 54 is fitted into the locking hole 42Y, and the locking protrusion 54 is locked to the locking hole 42Y.

For example, the front stopper 100 is accommodated in the accommodation space 62. The front stopper 100 is formed in a plate shape, for example. The front stopper 100 is accommodated in the accommodation space 62 from the front end side of the connector housing 50, for example. The front stopper 100 is inserted into the front receiving space 62 after each connection terminal 40 is inserted into the corresponding holding hole 52, for example. The front stopper 100 has a function of restricting the buckling piece 53 from being deflected toward the storage space 62, for example.

The front end portion of the terminal connecting portion 42 in which the through hole 42X is formed to protrude forward from the opening edge of the holding hole 52. That is, the tip end portion of the terminal connecting portion 42 is exposed to the outside of the holding hole 52 (the insertion portion 51).

As shown in fig. 6, each holding hole 52 has a bottom wall portion 55. The bottom wall 55 is provided below the locking piece 53, for example. For example, a concave portion 55X recessed downward is formed in the bottom wall portion 55 at a position facing the locking piece 53. The recess 55X is formed, for example, to be recessed downward from the upper surface of the bottom wall 55. The recess 55X is provided at a position facing the locking piece 53 via the connection terminal 40, for example. The concave portion 55X extends in the front-rear direction X, for example.

As shown in fig. 5, the insertion portion 51 has, for example, a support portion 57 protruding forward from the opening edge of the holding hole 52 and supporting the facing surface 42A of the terminal connection portion 42. The support portion 57 is provided below the terminal connection portion 42. The support portion 57 restricts the terminal connection portion 42 from tilting toward the counterpart terminal 200. The support portion 57 extends forward in the front-rear direction X, for example.

As shown in fig. 6, the support portion 57 is provided corresponding to only one end portion of the width direction (here, the left-right direction Y) ends of the connection terminals 40, for example. The support portion 57 of the present embodiment is configured to support only the outer end portion in the left-right direction Y of the connector housing 50 among the end portions in the width direction of the connection terminals 40. That is, the support portion 57 of the present embodiment supports the facing surface 42A of the terminal connecting portion 42 only at the outer end portion in the left-right direction Y.

The support portion 57 is formed in an L-shape in a planar shape as viewed from a direction opposite to the insertion direction (here, the front-rear direction X) of the connection terminal 40 with respect to the connector housing 50, for example. For example, the support portion 57 is formed in an L-shape in plan view as viewed from the penetrating direction of the holding hole 52. The support portion 57 includes, for example, a main body portion 57A for supporting the facing surface 42A of the terminal connection portion 42, and a rib 57B protruding upward from the main body portion 57A. In the support portion 57, for example, the main body portion 57A is formed integrally with the rib 57B continuously.

The main body 57A faces the facing surface 42A of the terminal connecting portion 42, for example. The main body 57A extends in the left-right direction Y, for example. The main body 57A is formed, for example, in a portion other than the recess 55X in the bottom wall 55 of the holding hole 52. The rib 57B extends, for example, in a direction in which the main body 57A faces the facing surface 42A (in this case, the up-down direction Z). The rib 57B extends upward in the up-down direction Z from the upper surface of the main body 57A, for example. The rib 57B extends upward from the upper surface of the end portion of the main body 57A in the left-right direction Y, for example. The rib 57B is provided, for example, so as to face the end surface of the terminal connecting portion 42 in the left-right direction Y. The rib 57B has a thickness in the left-right direction Y that is thicker than the thickness in the up-down direction Z of the main body 57A, for example.

(Structure of outer arrangement portion 70)

As shown in fig. 4, the outer arrangement portion 70 is formed to protrude rearward from the rear end of the insertion portion 51, for example. The outer arrangement portion 70 has a ring shape longer in the left-right direction Y than in the up-down direction Z, for example, when viewed in the front-rear direction X. The outer peripheral dimension of the outer placement portion 70 is formed smaller than the outer peripheral dimension of the insertion portion 51, for example.

Here, the "outer circumferential dimension of the a member" in the present specification refers to a length that makes the outer circumferential surface of the a member one turn in the circumferential direction of the a member. In the present specification, the "inner circumferential dimension of the a member" means a length that makes the inner circumferential surface of the a member one turn in the circumferential direction of the a member.

The outer placement portion 70 has, for example, a plurality of (two in this case) storage holes 71 aligned in the left-right direction Y. Each of the storage holes 71 is formed to penetrate the outer arrangement portion 70 in the front-rear direction X. Each of the receiving holes 71 is, for example, in the shape of a ring extending in the front-rear direction X.

As shown in fig. 5, a receiving groove 70X for receiving the rubber ring 93 is formed in the outer peripheral surface of the outer placement portion 70. A pair of receiving projections 72, 73 are formed on the outer peripheral surface of the outer placement portion 70. The housing projections 72, 73 protrude radially outward of the outer placement portion 70 from the outer peripheral surface of the outer placement portion 70. The housing protrusions 72 and 73 are formed in a ring shape so as to be continuous over the entire circumference of the outer arrangement portion 70. The pair of receiving projections 72, 73 are provided in parallel with a space therebetween in the front-rear direction X, for example. The receiving protrusion 72 and the receiving protrusion 73 have the same height from the outer peripheral surface of the outer placement portion 70, for example. For example, the height of each of the housing projections 72, 73 from the outer peripheral surface of the outer arrangement portion 70 is formed to be constant throughout the entire circumferential direction of the outer arrangement portion 70. The pair of receiving projections 72, 73 form a receiving groove 70X. The storage groove 70X is formed, for example, over the entire circumference of the outer peripheral surface of the outer placement 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 shield shell 170.

In addition, the term "equal" in the present specification includes not only the case of being exactly equal but also the case of slightly different comparison objects due to the influence of dimensional tolerance or the like.

(Structure of rubber ring 93)

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 formed, for example, in a ring shape that is continuous throughout the entire circumference of the outer arrangement portion 70. The rubber ring 93 of the present embodiment is formed in an oblong ring shape having an inner peripheral shape and an outer peripheral shape.

(Structure of outer arrangement portion 70)

As shown in fig. 7, a pair of lock arms 75 are provided on the outer peripheral surface of the outer arrangement portion 70. The pair of lock arms 75 are integrally provided to the outer arrangement portion 70, for example. The pair of lock arms 75 are provided on both side surfaces of the outer arrangement portion 70 in the up-down direction Z, for example, one for each. As shown in fig. 4, each lock arm 75 is provided between the outer peripheral surfaces of the adjacent receiving holes 71, for example.

Here, as shown in fig. 8, for example, a concave portion 70Y recessed radially inward of the outer placement portion 70 is formed on the outer peripheral surface of the outer placement portion 70 located between adjacent receiving holes 71. The concave portion 70Y extends rearward in the front-rear direction X from the housing convex portion 73, for example. The concave portion 70Y is formed to open rearward, for example. The recess 70Y is formed to open to the radial outside of the connector housing 50, for example.

As shown in fig. 7, each lock arm 75 includes, for example, a column portion 76 extending radially outward of the outward-disposed portion 70 from the bottom surface of the recess 70Y, and a locking piece 77 extending rearward in the front-rear direction X from the column portion 76. Each of the column portions 76 is formed to stand vertically in the up-down direction Z from the bottom surface of the recess 70Y, for example. The column portions 76 are provided at intervals from the storage protrusion 73, for example. Here, a storage space 79 is formed between each locking piece 77 and the bottom surface of each recess 70Y. Each of the storage spaces 79 is formed to open rearward, for example.

Each locking piece 77 extends rearward from a protruding distal end portion of the column portion 76, for example. The distal end portion (here, the rear end portion) of each locking piece 77 is formed to protrude rearward from the rear end surface of the housing hole 71 (see fig. 5), for example. A locking protrusion 78 protruding radially outward of the outer placement portion 70, which is the opposite side of the outer circumferential surface of the outer placement portion 70, is formed at the tip end portion of each locking piece 77. Each locking piece 77 is formed in a cantilever shape having a base end portion (here, a front end portion) connected to the column portion 76 as a fixed end and a tip end portion (here, a rear end portion) located on the opposite side of the base end portion in the front-rear direction X as a free end, for example. Each locking piece 77 has elasticity. Each of the locking pieces 77 is elastically deformable so that the tip end portion of the locking piece 77 is displaced in the up-down direction Z relative to the base end portion of the locking piece 77. Each of the locking pieces 77 is configured to be deflectable in the up-down direction Z by elastic deformation, for example. Each of the locking pieces 77 is configured to be elastically deformable toward the storage space 79, for example. Each locking piece 77 is formed at a rear end portion on the opposite side of the front end portion where the support portion 57 is formed, for example, in the axial direction of the connector housing 50.

The shield case 170 is fitted to the outer periphery of the outer arrangement portion 70 from the rear side. Here, the structure of the shield case 170 will be described.

(Structure of shield case 170)

The shield case 170 includes, for example, a coating portion 171 covering the outer periphery of the outer arrangement portion 70, and a fixing portion 172 formed so as to protrude from the outer periphery of the coating portion 171. The shield case 170 is a single component in which the cover 171 and the fixing portion 172 are integrally formed. As a material of the shield case 170, for example, a metal material such as copper-based material or aluminum-based material is used.

(Structure of coating portion 171)

The coating portion 171 is formed so as to surround the outer periphery of the outer arrangement portion 70 over the entire circumference, for example. The coating portion 171 is formed in, for example, a ring shape having an inner peripheral surface having a shape corresponding to the outer peripheral surface of the outer placement portion 70. The coating portion 171 of the present embodiment is formed in an annular shape.

The coating portion 171 has, for example, a first cylindrical portion 173 and a second cylindrical portion 174. The first cylinder 173 is provided in front of the second cylinder 174. The first cylindrical portion 173 is formed so as to surround the outer periphery of the receiving groove 70X in the outer arrangement portion 70 over the entire circumference. The inner peripheral dimension of the first cylindrical portion 173 is set to be equal to the outer peripheral dimension of the housing convex portions 72, 73 constituting the housing groove 70X, for example. The length of the first cylindrical portion 173 in the front-rear direction X is equal to the distance between the rear end surface of the insertion portion 51 and the rear end surface of the receiving protrusion 73, for example.

The inner peripheral dimension of the second cylindrical portion 174 is formed smaller than the inner peripheral dimension of the first cylindrical portion 173, for example. Therefore, a step is formed on the inner peripheral surface of the coating portion 171. For example, the front end surface of the second tube 174 is exposed from the first tube 173 on the inner side of the coating portion 171. The second cylindrical portion 174 is formed so as to circumferentially surround the outer peripheral surface of the outer arrangement portion 70 located rearward of the storage groove 70X. The inner peripheral dimension of the second cylindrical portion 174 is set to be equal to the outer peripheral dimension of the outer placement portion 70 except for the storage groove 70X, for example. The length of the second cylindrical portion 174 in the front-rear direction X is equal to the distance between the rear end surface of the receiving protrusion 73 and the locking protrusion 78, for example.

(Structure of fixing portion 172)

The fixing portion 172 is formed to protrude upward from the front end portion of the cover portion 171 (the first tubular portion 173), for example. The width of the fixing portion 172 in the lateral direction Y is wider than the width of the wrapping portion 171 in the lateral direction Y. At both ends of the fixing portion 172 in the left-right direction Y, connecting portions 175 protruding forward in the front-rear direction X are provided, respectively. Each of the connecting portions 175 has a fixing hole 175X penetrating the connecting portion 175 in the vertical direction Z.

The shield shell 170 is fitted to the outside of the outside arrangement portion 70 from the rear end side of the connector housing 50. The shield case 170 is fitted to the outside of the outside arrangement portion 70 before the rear stopper 120 is accommodated in the stopper accommodation portion 81, for example. The shield case 170 surrounds the outer periphery of the outer arrangement portion 70. For example, the rear end surface of the cover 171 (the second cylindrical portion 174) is engaged with the engagement convex portion 78 of the engagement piece 77, thereby positioning the shield shell 170 with respect to the connector housing 50 in the front-rear direction X. Here, when the shield case 170 is fitted to the outside of the outside arrangement portion 70, each locking piece 77 is pressed by the coating portion 171 of the shield case 170 and retreated toward the storage space 79. That is, when the shield case 170 is fitted, the locking pieces 77 are pressed against the inner peripheral surface of the covering portion 171 to be elastically deformed, and are deflected toward the bottom surface of the recess 70Y to be retracted into the housing space 79. Then, when the shield case 170 is fitted to the normal position, the locking protrusion 78 is elastically restored and locked to the rear end surface of the cover 171. At this time, for example, the front end surface of the first barrel portion 173 is in contact with the rear end surface of the insertion portion 51, and the front end surface of the second barrel portion 174 is in contact with the rear end surface of the receiving protrusion 73. For example, the first cylindrical portion 173 covers the outer peripheral surface of the outer placement portion 70 from the rear end surface of the insertion portion 51 to the receiving protrusion 73. Inside the first cylinder 173, the rubber ring 93 seals between the bottom surface of the storage groove 70X and the inner peripheral surface of the first cylinder 173. As shown in fig. 5, the second cylindrical portion 174 covers, for example, the outer peripheral surface of the outer placement portion 70 from the rear end surface of the receiving protrusion 73 to the rear end surface of the receiving hole 71.

The connecting portion 175 of the fixing portion 172 overlaps the fixing portion 18 such that the fixing hole 175X overlaps the bolt fixing hole 18X of the fixing portion 18 in the up-down direction Z, for example. The connecting portion 175 and the fixing portion 18 are fixed by bolts B2 inserted into the fixing holes 175X and the bolt fixing holes 18X. Thereby, the shield case 170 is fixed to the housing 15, and the shield case 170 is electrically connected with the housing 15.

(Structure of storage hole 71)

Each receiving hole 71 communicates with the corresponding holding hole 52. For example, a connection portion between the wire connection portion 41 and the core wire 21 of the wire 20 is accommodated in each accommodation hole 71. For example, an end portion of the insulating coating 22 of the electric wire 20 is accommodated in the accommodation hole 71.

As shown in fig. 9, the outer arrangement portion 70 has, for example, partition walls 80 provided between the plurality of receiving holes 71. The partition wall 80 is provided to separate, for example, two storage holes 71 aligned in the left-right direction Y. The partition wall 80 extends rearward in the front-rear direction X from, for example, the rear wall of the outer arrangement portion 70. The rear end surface of the partition wall 80 is provided, for example, on the front side (the side of the insertion portion 51) of the rear end surface of the storage hole 71. That is, the rear end surface of the partition wall 80 is disposed at a position that is set back to the front side than the rear end surface of the storage hole 71.

For example, an annular rubber plug 110 attached to the electric wire 20 is accommodated in each accommodation hole 71. The rubber stopper 110 seals between the outer peripheral surface of the electric wire 20 and the inner peripheral surface of the receiving hole 71. For example, a stopper accommodating portion 81 accommodating the rear stopper 120 is formed at the rear end portion of each accommodating hole 71. The stopper housing 81 is provided, for example, at a position rearward of the partition wall 80. The stopper housing portion 81 is configured by, for example, communicating the internal spaces at the rear end portions of the plurality of housing holes 71 with each other. For example, the internal spaces at the rear end portions of the plurality of receiving holes 71 communicate with each other through a space located behind the partition wall 80. The stopper housing portion 81 is constituted by, for example, an internal space at the rear end portion of the plurality of housing holes 71 and a space communicating the internal space. The stopper housing 81 is formed to be opened rearward. For example, the rear stopper 120 is inserted into the stopper housing 81 in the insertion direction D1. The insertion direction D1 of the present embodiment is a direction parallel to the front-rear direction X, and is a direction from the rear to the front of the front-rear direction X.

(Structure of stopper storing portion 81)

As shown in fig. 8, the stopper housing portion 81 has a slit 82 provided in the recess 70Y, for example. The slit 82 is provided on the bottom surface of the recess 70Y. The slit 82 extends from the rear end surface of the bottom surface of the recess 70Y in the insertion direction D1 (here, forward). The slit 82 opens rearward. The slit 82 extends, for example, to a position forward of the rear end surface of the partition wall 80. The slit 82 is provided at a position overlapping the locking piece 77 in the up-down direction Z. The slit 82 is provided, for example, at the center of the recess 70Y in the lateral direction Y.

The stopper housing 81 includes, for example, a housing 83 provided in the partition wall 80. The storage portion 83 is provided between the pair of concave portions 70Y in the up-down direction Z, for example. The receiving portion 83 extends in the insertion direction D1 (forward in this case) from the rear end surface of the partition wall 80, for example. The receiving portion 83 is opened rearward.

The housing portion 83 has, for example, an upper wall portion 84, a bottom wall portion 85, and a pair of side wall portions 86. The side wall portions 86 are provided to separate the housing portions 83 from the housing holes 71, for example. The rear end surfaces of the side wall portions 86 are provided, for example, on the front side of the rear end surfaces of the upper wall portion 84 and the bottom wall portion 85.

For example, slits 87 are formed in rear end surfaces of the upper wall portion 84 and the bottom wall portion 85. The slit 87 extends from the rear end surfaces of the upper wall portion 84 and the bottom wall portion 85 in the insertion direction D1 (forward in this case). The slit 87 is opened rearward, for example. The slit 87 extends to the position of the side wall 86 in the front-rear direction X, for example. The slit 87 is provided at a position overlapping the locking piece 77 in the up-down direction Z, for example. The slit 87 is provided at a position overlapping the slit 82 in the up-down direction Z, for example. The slit 87 is provided, for example, in a central portion of the accommodating portion 83 in the left-right direction Y.

(Structure of rear stopper 120)

As shown in fig. 9, the rear stopper 120 is accommodated in the stopper accommodating portion 81. The rear stopper 120 is provided, for example, behind the rubber stopper 110. The rear stopper 120 suppresses the rubber stopper 110 from coming off the receiving hole 71 by, for example, pressing the rubber stopper 110 from the rear.

The rear stopper 120 includes, for example, a stopper portion 130 that is accommodated in the rear end portion of the accommodation hole 71, and a coupling portion 140 that is coupled to the stopper portion 130. The rear stopper 120 of the present embodiment includes two stopper portions 130 and a coupling portion 140 coupling the two stopper portions 130. The two stopper portions 130 and the connecting portion 140 are arranged in a direction (here, the left-right direction Y) intersecting the insertion direction D1, for example. The two stoppers 130 are provided, for example, to sandwich the connecting portion 140 in the left-right direction Y. The rear stopper 120 is, for example, a single component in which the stopper 130 and the connecting portion 140 are integrally formed in a continuous manner.

As shown in fig. 5, each stopper 130 has, for example, a ring shape extending in the front-rear direction X. Each stopper 130 has an outer peripheral surface, for example, along the shape of the inner peripheral surface of the receiving hole 71. Each stopper 130 has, for example, a through hole 130X penetrating each stopper 130 in the insertion direction D1 (here, the front-rear direction X). The inner peripheral surface of each through hole 130X is formed in a shape along the outer peripheral surface of the insulating coating 22 of the electric wire 20, for example. The front end surface of each stopper 130 contacts the rear end surface of the rubber stopper 110, for example. Each stopper 130 has, for example, a plurality of fixing claws 131 formed on the outer peripheral surface of each stopper 130. The stopper housing portion 81 is provided with the same number of locking holes 88 as the number of the fixing claws 131. The rear stopper 120 is fixed to the stopper housing 81 by fitting the plurality of fixing claws 131 of each stopper 130 into the locking holes 88. Further, each wire 20 passes through the through hole 130X of each stopper 130 and is led out from the rear end of the receiving hole 71 to the outside of the connector housing 50.

As shown in fig. 10, the coupling portion 140 is provided between the two stopper portions 130, for example, and couples the two stopper portions 130. The connecting portion 140 is formed in a flat plate shape, for example. The connecting portion 140 has a predetermined thickness in the up-down direction Z, for example. The coupling portion 140 extends in the left-right direction Y between the two stopper portions 130, for example. The length of the connecting portion 140 in the front-rear direction X is equal to the length of each stopper 130 in the front-rear direction X, for example. The front end surface of the connecting portion 140 is formed on the same plane as the front end surface of each stopper 130, for example. The rear end surfaces of the coupling portions 140 are formed on the same plane as the rear end surfaces of the stopper portions 130, for example.

For example, a wall portion 141 extending in a direction (in this case, the up-down direction Z) intersecting both the arrangement direction (in this case, the left-right direction Y) in which the stopper portion 130 and the connecting portion 140 are arranged and the insertion direction D1 (in this case, the front-rear direction) is provided at the rear end portion of the connecting portion 140. For example, when the rear stopper 120 is stored in the stopper storing portion 81 (see fig. 9), the wall portion 141 contacts the partition wall 80 (see fig. 9). The wall portion 141 restricts, for example, the amount of insertion of the rear stopper 120 with respect to the connector housing 50 (see fig. 9). The wall portion 141 protrudes from both upper and lower surfaces of the coupling portion 140 in the up-down direction Z, for example. For example, the wall portion 141 protrudes upward from the upper surface of the coupling portion 140, and protrudes downward from the lower surface of the coupling portion 140. The wall portion 141 extends over the entire length of the connecting portion 140 in the lateral direction Y, for example. The length of the wall portion 141 in the front-rear direction X is shorter than the length of the connecting portion 140 in the front-rear direction X. The rear end surface of the wall portion 141 is formed on the same plane as the rear end surface of each stopper 130, for example.

As shown in fig. 7, for example, a pair of projections 142, 143 protruding toward the two locking pieces 77 are provided in the coupling portion 140. Each of the projections 142, 143 contacts the corresponding locking piece 77. A part of each of the projections 142 and 143 is accommodated in the accommodation space 79. The projections 142, 143 are provided at positions overlapping the locking piece 77 in the up-down direction Z, for example. As shown in fig. 10, the protrusions 142, 143 protrude from the coupling portion 140 in a direction (in this case, the up-down direction Z) intersecting both the arrangement direction (in this case, the left-right direction Y) in which the stopper portion 130 and the coupling portion 140 are arranged and the insertion direction D1 (in this case, the front-rear direction), for example.

The protrusions 142 and 143 are provided at, for example, the center of the connecting portion 140 in the left-right direction Y. The protrusions 142 and 143 are provided at positions overlapping each other in the up-down direction Z, for example. The projection 142 protrudes upward from the upper surface of the coupling portion 140, for example. The projection 142 projects upward from the upper surface of the wall 141, for example. For example, the height of the protrusion 142 in the up-down direction Z from the upper surface of the coupling portion 140 is higher than the height of the wall portion 141 in the up-down direction Z from the upper surface of the coupling portion 140. The projection 143 protrudes downward from the lower surface of the coupling portion 140, for example. The projection 143 projects downward from the lower surface of the wall 141, for example. For example, the height of the protrusion 143 in the up-down direction Z from the lower surface of the coupling portion 140 is higher than the height of the wall portion 141 in the up-down direction Z from the lower surface of the coupling portion 140. The projections 142, 143 are formed to extend in a direction (here, the front-rear direction X) in which the locking piece 77 (see fig. 7) extends, for example. The protrusions 142 and 143 extend over the entire length of the connecting portion 140 in the front-rear direction X, for example. For example, the length of each protrusion 142, 143 in the front-rear direction X is longer than the length of the wall 141 in the front-rear direction X.

For example, a protruding portion 145 protruding from the front end surface in the insertion direction D1 (in this case, the front end surface) is provided on the rear end surface in the insertion direction D1 of the coupling portion 140. The protruding portion 145 protrudes forward from the front end surface of the stopper 130, for example. The protruding portion 145 extends in the front-rear direction X, for example. The protruding portion 145 is provided, for example, at a central portion of the connecting portion 140 in the left-right direction Y. The protruding portion 145 is provided at the connecting portion 140 at a portion connected to the base end portions of the protrusions 142, 143, for example. The protruding portion 145 extends, for example, in an arrangement direction (here, the left-right direction Y) in which the stopper portion 130 and the connecting portion 140 are arranged. The length of the protruding portion 145 in the left-right direction Y is shorter than the length of the connecting portion 140 in the left-right direction Y, for example. The protruding portion 145 has a predetermined thickness in the up-down direction Z, for example. The length of the protruding portion 145 in the up-down direction Z is equal to the length of the connecting portion 140 in the up-down direction Z, for example. The length of the protruding portion 145 in the up-down direction Z is set to be, for example, a length that can be accommodated in the accommodating portion 83 shown in fig. 8.

For example, a recess 146 is formed on the lower surface of the protruding portion 145. The concave portion 146 is formed, for example, to be concave upward from the lower surface of the protruding portion 145. The concave portion 146 is provided, for example, at the center of the protruding portion 145 in the left-right direction Y. The recess 146 extends in the front-rear direction X, for example. The concave portion 146 extends over the entire length of the protruding portion 145 in the front-rear direction X, for example.

The rear stopper 120 of the present embodiment has a pair of divided bodies 150 and 151 and a hinge 152 that connects one end portions of the divided bodies 150 and 151 to each other. The segment 150 has, for example, a protrusion 142. The divided body 151 has, for example, a protrusion 143. Hinge 152 is flexible. The hinge 152 is formed thinner than the divided bodies 150 and 151, for example. The hinge 152 is connected to one end of the split bodies 150 and 151 in the left-right direction Y, for example. The hinge 152 connects the pair of divided bodies 150 and 151 to be openable and closable. That is, the rear stopper 120 is configured such that the pair of divided bodies 150 and 151 can be opened and closed with the hinge 152 as a fulcrum. For example, in the case of a closed posture (see fig. 10) in which the pair of divided bodies 150, 151 is closed, the rear stopper 120 constitutes the stopper 130, the coupling portion 140, and the protruding portion 145 described above. At this time, slits 155 extending in the front-rear direction X are formed in the stopper 130, the coupling portion 140, and the protruding portion 145. The slit 155 extends over the entire length of the split bodies 150 and 151 in the left-right direction Y, for example.

As shown in fig. 9, the rear stopper 120 is inserted from the rear in the insertion direction D1 with respect to the stopper housing portion 81 of the connector housing 50. The rear stopper 120 is inserted into the stopper accommodating portion 81 after the shield case 170 is fitted to the outside of the outside arrangement portion 70, for example. When the rear stopper 120 is inserted into the stopper housing 81, each stopper 130 of the rear stopper 120 is housed in the corresponding housing hole 71. As shown in fig. 7, the projections 142 and 143 of the rear stopper 120 are inserted into the storage space 79 and the slits 82 and 87 of the connector housing 50. At this time, the projections 142 and 143 are inserted into the storage space 79 and the slits 82 and 87 while bringing the tip end surfaces (upper end surfaces in this case) of the projections 142 and the tip end surfaces (lower end surfaces in this case) of the projections 143 into contact with the locking pieces 77, respectively. When the projections 142 and 143 are accommodated in the respective accommodation spaces 79, the locking pieces 77 are supported by the projections 142 and 143, and thus the locking pieces 77 are restricted from being elastically deformed toward the accommodation spaces 79. Here, when the shield case 170 is not fitted to the normal position, for example, when the locking convex portion 78 is pressed from the inner peripheral surface of the cover 171 toward the bottom surface of the concave portion 70Y, the projections 142, 143 cannot be inserted into the storage space 79. This is because the locking convex portion 78 deflects toward the storage space 79, and the length of the storage space 79 in the up-down direction Z is narrowed. Therefore, by inserting the rear stopper 120 into the stopper housing 81, it is possible to detect whether the shield shell 170 is fitted to the normal position with respect to the connector housing 50. The front end surfaces of the projections 142, 143 contact the rear side walls of the slits 82, 87, for example.

When the rear stopper 120 is inserted into the stopper housing 81, the protruding portion 145 of the rear stopper 120 is housed in the housing 83 of the stopper housing 81. At this time, the end surfaces (here, the upper surface and the lower surface) of the protruding portion 145 intersecting the insertion direction D1 are in contact with the inner surface of the housing portion 83. For example, the upper surface of the protruding portion 145 is in contact with the lower surface of the upper wall portion 84 constituting the inner surface of the receiving portion 83. The lower surface of the protruding portion 145 is in contact with, for example, the upper surface of the bottom wall portion 85 constituting the inner surface of the housing portion 83. For example, the lower surface of the protruding portion 145 constituting the side wall of the recess 146 is in contact with the upper surface of the bottom wall portion 85.

Next, the operational effects of the present embodiment will be described.

(1) The rear stopper 120 for preventing the annular rubber plug 110 attached to the electric wire 20 from coming off is provided with protrusions 142 and 143 that come into contact with the locking piece 77 locked to the shield case 170. According to this structure, the projections 142 and 143 contact the locking piece 77 in the storage space 79, whereby the locking piece 77 is supported by the projections 142 and 143, and the locking piece 77 is restrained from being elastically deformed toward the storage space 79. Therefore, the locking piece 77 and the shield shell 170 can be prevented from being accidentally released, and the shield shell 170 can be prevented from coming off the connector housing 50. Further, since the locking piece 77 is supported by the projections 142 and 143, buckling of the locking piece 77 can be suppressed even when the locking piece 77 is long, and a decrease in the holding force of the locking piece 77 on the shield case 170 can be suppressed. This can prevent the shield shell 170 from falling off the connector housing 50.

(2) The coupling portion 140 of the rear stopper 120 is provided with a protruding portion 145 protruding in the insertion direction D1 than the stopper portion 130. Further, the connector housing 50 is provided with a receiving portion 83 for receiving the protruding portion 145. According to this structure, the protruding portion 145 is inserted deeper into the connector housing 50 than the stopper 130 of the pressing rubber stopper 110. Therefore, even when water pressure is applied to the rubber stopper 110, for example, the rear stopper 120 can be restrained from tilting in a direction intersecting the insertion direction D1. This can prevent the rear stopper 120 from falling off the connector housing 50 due to the inclination of the rear stopper 120.

(3) The upper surface of the protruding portion 145 is in contact with the lower surface of the upper wall portion 84 constituting the inner surface of the housing portion 83, and the lower surface of the protruding portion 145 is in contact with the upper surface of the bottom wall portion 85 constituting the inner surface of the housing portion 83. Thus, even when water pressure is applied to the rubber stopper 110, for example, the rear stopper 120 can be appropriately prevented from tilting in a direction intersecting the insertion direction D1.

(4) A support portion 57 is provided which projects forward from the front end surface of the holding hole 52 of the connector housing 50 and supports the facing surface 42A of the terminal connection portion 42. According to this structure, since the facing surface 42A of the terminal connecting portion 42 is supported by the supporting portion 57, the terminal connecting portion 42 can be restrained from tilting toward the counterpart terminal 200. Accordingly, when the connector 30 is inserted into the housing 15 to be connected, the contact between the distal end portion of the terminal connecting portion 42 and the counterpart terminal 200 can be suppressed. For example, when the connector 30 is inserted into the housing 15, the tip end portion of the terminal connecting portion 42 can be restrained from coming into contact with the terminal block holding the counterpart terminal 200. Accordingly, the insertion operation of the connector 30 can be smoothly performed, and the insertion operation of the connector 30 can be improved.

(5) The support portion 57 is constituted by a main body portion 57A opposed to the opposed surface 42A of the terminal connection portion 42 and a rib 57B protruding from the main body portion 57A in a direction in which the main body portion 57A is opposed to the terminal connection portion 42. According to this structure, the rib 57B is provided in the main body 57A, so that the strength of the entire support 57 can be improved, and the rigidity of the support 57 can be improved. Therefore, the terminal connection portion 42 can be appropriately supported by the support portion 57, and the inclination of the terminal connection portion 42 toward the counterpart terminal 200 can be appropriately suppressed.
