[0025] [Explanation of Embodiments of the Present Disclosure]

[0026] First, an embodiment of the present disclosure will be explained.

[0027] The electric wire with a connector of the present disclosure is as follows.

[0028] (1) A wire with a connector has: a wire with a terminal including a covered wire and a terminal member provided at an end portion of the covered wire; and a connector housing including a main member formed with a cavity and a cover member attached to the main member, a tip end portion of the terminal member is housed in the cavity, a rear end portion of the terminal member protrudes outside the cavity, is covered by the cover member or by the cover member and the main member, and the cover member is attachable to the main member in a state where the rear end portion of the terminal member protrudes outside the cavity, with a sliding movement in a direction crossing a length direction of the cavity. The terminal member is inserted into the cavity of the main member before the cover member is attached, so that an insertion amount of the terminal member into the cavity is reduced. The cover member is attached to the main member after the terminal member is inserted into the cavity, so that the rear end portion of the terminal member is covered. Thus, the wire with a terminal can be easily housed in the connector housing.

[0029] (2) In the wire with a connector of (1), the cover member can include a first cover member and a second cover member, the first cover member and the second cover member are attachable to the main member with a sliding movement in directions crossing each other in a state where the rear end portion of the terminal member protrudes outside the cavity, the first cover member has a first wall portion covering a portion of the rear end portion of the terminal member along a circumferential direction, and the second cover member has a second wall portion covering another portion of the rear end portion of the terminal member along the circumferential direction. Thus, the entire circumference of the rear end portion of the terminal member can be covered by the two cover members attached to the main member.

[0030] (3) In the wire with a connector of (1), the main member can have a first wall portion formed at an end surface of one opening portion of the main member formed with the cavity, the first wall portion covering another portion of the rear end portion of the terminal member along a circumferential direction, and the cover member can have a second wall portion covering a portion of the rear end portion of the terminal member along the circumferential direction. Thus, the entire circumference of the rear end portion of the terminal member can be covered by the main member and the cover member attached to the main member.

[0031] (4) In any one of the wires with a connector of (1) to (3), a fitting portion and a fitted portion maintaining an attached state can be provided at the main member and the cover member, and the fitting portion and the fitted portion are fitted in a direction in which the main member and the cover member are slid in a direction crossing a length direction of the cavity. Thus, the fitting portion and the fitted portion can be fitted when the main member and the cover member are slid in the direction crossing the length direction of the cavity.

[0032] (5) In any one of the wire with connector of (1) to (4), the wire with terminal can further include a sealing member installed to the middle portion of the terminal member, the sealing member is arranged inside the cavity, and the portion of the terminal member, which is behind the portion where the sealing member is installed, protrudes outward from the cavity. Thus, the amount of movement of the sealing member inside the cavity is reduced. Thus, the wire with terminal can be easily housed in the connector housing.

[0033] (6) In the wire with connector of (5), the cross-sectional shape of the portion of the cavity where the sealing member is arranged can be circular, and the periphery of the rear end portion of the terminal member can be covered by four wall portions that come together to form a square tube shape. Thus, the sealing member and the inner surface of the cavity easily fit together. In addition, the shape of the wall portions that cover the rear end portion of the terminal member becomes a simple shape.

[0034] (7) In addition, the connector housing of the present disclosure, which houses the wire with terminal having a terminal member provided at the end portion, includes a main body member formed with a cavity into which the tip end portion of the terminal member is inserted, and a cover member installed to the main body member, the rear end portion of the terminal member protruding outside the cavity is covered by the cover member or by the cover member and the main body member, the cover member can be installed to the main body member in conjunction with sliding movement in a direction that intersects the length direction of the cavity with the rear end portion of the terminal member protruding outside the cavity. By inserting the terminal member into the cavity of the main body member before installing the cover member, the amount of insertion of the terminal member into the cavity is reduced. By installing the cover member to the main body member after the terminal member is inserted into the cavity, the rear end portion of the terminal member is covered. Thus, the wire with terminal can be easily housed in the connector housing.

[0035] [Details of the Embodiments of the Present Disclosure]

[0036] Hereinafter, specific examples of the wire with connector and the connector housing of the present disclosure will be described with reference to the drawings. Furthermore, the present disclosure is not limited to these examples, but is shown by the claims, including all modifications within the meaning and scope equivalent to the claims.

In addition, in the present disclosure, as shown in Figure 1 the length direction of the cavity 63 is set as the X direction, and the two directions orthogonal to the length direction of the cavity 63 are set as the Y direction and the Z direction.

[0040] <Electric wire with terminal>

[0041] In addition to Figure 1 , reference is also made to Figure 2 The electric wire 20 with terminal is described. Figure 2 is an exploded perspective view showing the electric wire 20 with terminal.

[0042] The electric wire 20 with terminal includes the covered electric wire 22 and the terminal member 30. The terminal member 30 and the portion of the covered electric wire 22 connected to the terminal member 30 are housed in the housing space in the connector housing 60. The portion of the covered electric wire 22 on the other end side from the portion connected to the terminal member 30 extends outward from the housing space in the connector housing 60. The top end portion of the terminal member 30 is housed in the cavity 63 in the housing space. The rear end portion of the terminal member 30 protrudes outside the cavity 63. The rear end portion of the terminal member 30 is housed in the space surrounded by the wall portion in the housing space.

[0043] The covered electric wire 22 has the conductor core wire 24 and the insulating covering portion 26. Here, the conductor core wire 24 is a stranded wire. The stranded wire is formed by twisting a plurality of wire materials. Such wire materials are formed using a conductor such as copper, copper alloy, aluminum, aluminum alloy, or the like as a material. The insulating covering portion 26 covers the conductor core wire 24. The insulating covering portion 26 is formed by extrusion molding a resin material around the conductor core wire 24 or by applying an insulating paint. The top end of the conductor core wire 24 protrudes outward from the insulating covering portion 26 and forms a core wire exposed portion.

[0044] The terminal member 30 includes a wire connecting portion 33 connected to the covered wire 22 and an opposite side connecting portion 41 connected to an opposite side terminal. Here, the terminal member 30 is configured by three members of a joint terminal 32, a connector terminal 40, and a relay conductor 46. The wire connecting portion 33 is provided to the joint terminal 32. The opposite side connecting portion 41 is provided to the connector terminal 40. The relay conductor 46 is connected to the joint terminal 32 and the connector terminal 40, respectively. The joint terminal 32 and the connector terminal 40 are connected by the relay conductor 46.

[0045] The joint terminal 32 includes the wire connecting portion 33 and a relay conductor connecting portion 36. Here, the joint terminal 32 is crimp-connected to the covered wire 22 and the relay conductor 46, respectively. The joint terminal 32 is formed by, for example, bending a conductor plate. However, the joint terminal 32 can be connected to the covered wire 22 or the relay conductor 46 by welding, crimping, or the like.

[0046] The wire connecting portion 33 has a wire barrel 34 and an insulating barrel 35. The wire barrel 34 is crimped to the core wire exposed portion of the end portion of the conductor core wire 24. The insulating barrel 35 is crimped to the insulating covering portion 26. The wire barrel 34 and the insulating barrel 35 are open barrels. The insulating barrel 35 can be omitted from the wire connecting portion 33.

[0047] The relay conductor connecting portion 36 has a wire barrel 37 and an insulating barrel 38. The wire barrel 37 is crimped to the relay conductor 46. The insulating barrel 38 is crimped to the sealing member 50. The wire barrel 37 and the insulating barrel 38 are open barrels. The insulating barrel 38 can be omitted from the relay conductor connecting portion 36.

[0048] The connector terminal 40 includes the opposite side connecting portion 41 and a relay conductor connecting portion 42. As described above, the opposite side connecting portion 41 is formed in a male terminal shape. The opposite side connecting portion 41 can be formed in a female terminal shape. Here, the connector terminal 40 is crimp-connected to the relay conductor 46. The connector terminal 40 is formed by, for example, bending a conductor plate. However, the connector terminal 40 can be connected to the relay conductor 46 by welding, crimping, or the like.

[0049] The opposite side connecting portion 41 has a box portion formed in a box shape and a conductor pin. The conductor pin protrudes from the top end surface of the box portion. The top end portion of the conductor pin protrudes outward from the cavity 63. The conductor pin is inserted into a female terminal on the opposite side. A spring contact portion or the like is appropriately provided inside the female terminal on the opposite side. Inside the female terminal on the opposite side, the spring contact portion or the like is connected to the conductor pin.

[0050] The relay conductor connecting portion 42 has a wire barrel 43 and an insulating barrel 44. The wire barrel 43 is crimped to the relay conductor 46. The insulating barrel 44 is crimped to the sealing member 50. The insulating barrel 44 can be omitted from the relay conductor connecting portion 42.

[0051] The relay conductor 46 is formed in a conductor. The relay conductor 46 is formed in a cylindrical rod shape. The relay conductor 46 can also be formed in a cylindrical rod shape. The relay conductor 46 is longer than the sealing member 50. The both ends of the relay conductor 46 in the length direction protrude outward of the sealing member 50. The both ends of the relay conductor 46 are crimped to the spools 37, 43, respectively.

[0052] The terminal-equipped electric wire 20 is provided with a mounting portion 48. The sealing member 50 is mounted to the mounting portion 48. The outer surface of the mounting portion 48 is formed in a circular shape. Here, the middle portion of the relay conductor 46 in the length direction is formed as the mounting portion 48.

[0053] Here, the terminal-equipped electric wire 20 further includes the sealing member 50. The sealing member 50 is mounted to the middle portion of the terminal member 30. The sealing member 50 is mounted to the mounting portion 48. The sealing member 50 is also housed in the housing space in the connector housing 60. Here, the sealing member 50 is housed in the cavity 63 in the housing space.

[0054] The sealing member 50 has a sealing body 52 and a held portion 54. The sealing member 50 is formed with a through hole 56. The relay conductor 46 passes through the through hole 56. The sealing body 52 and the held portion 54 are arranged in the axial direction of the through hole 56. Here, the held portion 54 is provided on both sides of the sealing body 52. The held portion 54 can be provided on either side of the sealing body 52 only. The held portion 54 can be omitted.

[0055] The sealing body 52 is a portion that stops water between one opening portion and the other opening portion of the cavity 63 in a state where the terminal-equipped electric wire 20 is inserted into the cavity 63. In the outer surface of the sealing body 52, annular concave portions and annular convex portions are alternately connected in the length direction. The sealing body 52 is located between the junction terminal 32 and the connector terminal 40 in the length direction. The annular convex portions in the sealing body 52 protrude outward in the radial direction beyond the junction terminal 32 and the connector terminal 40.

[0056] In a state before the terminal-equipped electric wire 20 is inserted into the cavity 63, the outer diameter of the sealing body 52 is set to be the same as or larger than the inner diameter of the cavity 63. In the housed state, the annular convex portions of the sealing body 52 are in close contact with the inner surface of the cavity 63 over the entire circumference.

[0057] The held portion 54 is a portion that is crimped to the insulating tubes 38, 44 in a state of being covered on the relay conductor 46. Thus, the held portion 54 is positioned and held to the connector terminal 40 and the terminal 32, and the sealing member 50 is positioned and held to the wire 20 with the terminal. In a case where the held portion 54 is omitted, the mounting portion 48 is preferably formed in a shape that can position and hold the sealing member 50. For example, a groove can be formed in the mounting portion 48. By receiving the sealing member 50 in the groove, the sealing member 50 is positioned and held to the mounting portion.

[0058] In the received state, the sealing member 50 is received in the cavity 63. By providing the sealing member 50, the one opening portion and the other opening portion of the cavity 63 are water-stopped. As a liquid that becomes a water-stopping object of the sealing member 50, water, oil, or the like can be assumed. The oil is, for example, oil (working oil) for a control operation for automatic shifting in an automatic transmission. The water-stopping between the one opening portion and the other opening portion of the cavity 63 is performed, for example, as follows.

[0059] The inside of the mounting portion 48 is formed as a solid. Thus, the penetration of the liquid from one of the one opening portion and the other opening portion of the cavity 63 to the other along the inside of the mounting portion 48 can be suppressed. The inside of the mounting portion 48 can also be hollow. Even in this case, when at least one of the mounting portions 48 is closed in the length direction, the penetration of the liquid from one of the one opening portion and the other opening portion of the cavity 63 to the other along the inside of the mounting portion 48 can be suppressed.

[0060] The inner surface (inner peripheral surface of the through-hole 56) in the sealing body 52 is formed in a circular shape. In the received state, the inner surface in the sealing body 52 is in close contact with the outer surface of the mounting portion 48 throughout the entire circumference. Thus, the sealing body 52 can suppress the penetration of the liquid from one of the one opening portion and the other opening portion of the cavity 63 to the other along the sealing body 52 and the mounting portion 48. Furthermore, it is only necessary that the inner surface of at least a portion of the sealing body 52 in the length direction be in close contact with the outer surface of the mounting portion 48 throughout the entire circumference. The inner surface of the sealing body 52 can also be formed smaller than the outer surface of the mounting portion 48 in a state before being mounted to the mounting portion 48. It can also be that, in the received state, the inner surface of the sealing body 52 is pressed to the outer surface of the mounting portion 48 by the pressure from the cavity 63.

[0061] The outer surface of the sealing body 52 is formed in a circular shape. In the received state, the outer surface of the annular protrusion in the sealing body 52 is in close contact with the inner surface of the cavity 63 throughout the entire circumference. Thus, the penetration of the liquid from one of the one opening portion and the other opening portion of the cavity 63 to the other along the sealing body 52 and the connector housing 60 can be suppressed.

[0062] The sealing member 50 is arranged inside the cavity 63. The portion of the terminal member 30, which is located rearward of the portion where the sealing member 50 is attached, protrudes outward from the cavity 63. Here, the end portion of the relay conductor 46 and the terminal 32 are located outward of the cavity 63.

[0063] <Connector housing>

[0064] In addition to Figure 1 , reference is also made to Figures 3 to 5 The connector housing 60 is described in detail. Figure 3 is a perspective view showing the connector housing 60 of Embodiment 1. Figure 4 is an exploded perspective view showing the connector housing 60 of Embodiment 1. Figure 5 is an exploded perspective view showing the connector housing 60 of Embodiment 1. Figure 3 and Figure 4 is a perspective view viewed from the same direction as Figure 5 is a perspective view viewed from a different direction than Figure 3 and Figure 4

[0065] The connector housing 60 includes a main member 61 and a cover member 70, 80 attached to the main member 61.

[0066] The main member 61 includes a housing main body 62. Here, the main member 61 further includes a first fitting portion 66. The main member 61 is formed of a resin or the like having insulating properties. The main member 61 is, for example, an injection-molded product.

[0067] The cavity 63 is formed in the housing main body 62. The cavity 63 is formed in at least one. Here, the cavity 63 is formed in a plurality. The plurality of cavities 63 are formed in a manner arranged in multiple layers and multiple columns. The plurality of cavities 63 can also be formed in a manner arranged in one layer and multiple columns. In Figure 4 , the Z direction is formed as the layer direction, and the Y direction is formed as the column direction. In Figure 4 the example shown in the drawing, the plurality of cavities 63 are formed in a manner arranged in four layers and five columns.

[0068] The cavity 63 is formed in a manner penetrating the housing main body 62. One opening portion of the cavity 63 is opened at one end surface of the housing main body 62 (an end surface facing the negative side of the X direction). The other opening portion of the cavity 63 is opened at the other end surface of the housing main body 62 (an end surface facing the positive side of the X direction).

[0069] ​The terminal-equipped electric wire 20 is inserted into the cavity 63 from one opening portion. The terminal-equipped electric wire 20 and the housing main body 62 are positioned and held at predetermined positions, for example, by a lance portion or the like. The other opening portion is a portion through which a conductor pin provided to a male terminal passes. In this example, the terminal housed in the cavity 63 is a male terminal. In this case, the conductor pin provided to the male terminal protrudes to the outside of the cavity 63 through the other opening portion. Further, the conductor pin provided to the male terminal and a female terminal on the other side are connected to each other outside the cavity 63. The other opening portion is preferably formed smaller than the box-shaped portion in the other side connecting portion 41 and larger than the conductor pin. Thus, it is possible to suppress the male terminal housed in the cavity 63 from falling out of the other opening portion. However, the terminal housed in the cavity 63 can also be a female terminal. In this case, the conductor pin provided to a male terminal on the other side is inserted into the cavity 63 through the other opening portion. Further, the female terminal and the conductor pin provided to the male terminal on the other side are connected to each other in the cavity 63.

[0070] The sealing member 50 is also arranged at a predetermined position in the cavity 63 in a state in which the terminal-equipped electric wire 20 is arranged at a predetermined position in the cavity 63. Here, the cross-sectional shape of the portion of the cavity 63 in which the sealing member 50 is arranged is circular. As shown in FIG. 6, here, the cross-sectional shape of the one opening portion of the cavity 63 is circular. The cross-sectional shape of the portion of the cavity 63 from the one opening portion to the portion in which the sealing member 50 is arranged is circular. The cross-sectional shape of the portion of the cavity 63 from the portion in which the sealing member 50 is arranged to the other opening portion can be appropriately set. Figure 4

[0071] The main body member 61 is provided with a protruding wall portion 64. The protruding wall portion 64 protrudes from one end surface of the one opening portion in which the cavity 63 is formed. The protruding wall portion 64 is arranged between the cavities 63 arranged in the layer direction. The protruding wall portion 64 is located at a position offset in the Z direction with respect to the cavities 63. The protruding wall portion 64 is provided in order to cover the portion not covered by the second cover member 80. The protruding wall portion 64 can also be omitted. The protruding dimension (dimension in the X direction) of the protruding wall portion 64 is the same as the interval between the tip end of the slit 72 in the first cover member 70 and the end surface of the first cover member 70. The width dimension (dimension in the Y direction) of the protruding wall portion 64 is the same as the width dimension of the cavity 63. The thickness dimension (dimension in the Z direction) of the protruding wall portion 64 is the same as or slightly smaller than the dimension of the gap between two cavities 63.

[0072] Further, here, the interval between the cavity 63 of the second layer and the cavity 63 of the third layer is larger than the interval between the other layers. Therefore, two protruding wall portions 64 are provided between the cavity 63 of the second layer and the cavity 63 of the third layer.

[0073] ​The main body member 61 is provided with a protruding frame portion 65. The protruding frame portion 65 positions the first cover member 70. The protruding frame portion 65 protrudes from one end surface of the one opening portion through which the cavity 63 is formed. The protruding frame portion 65 is provided in a manner of surrounding the plurality of cavities 63. The protruding frame portion 65 is open on one side (the positive side in the Z direction). The first cover member 70 is inserted from the opening to the inside of the protruding frame portion 65. The protruding dimension (dimension in the X direction) of the protruding frame portion 65 is the same as the protruding dimension of the protruding wall portion 64, and is the same degree as the interval between the tip of the slit 72 in the first cover member 70 and the end surface of the first cover member 70. The first fitting portion 66 is provided at the end portion of the protruding frame portion 65 (portion offset in the Y direction with respect to the opening of the protruding frame portion 65).

[0074] The first fitting portion 66 is fitted with the first fitted portion 74 provided to the first cover member 70. The first fitting portion 66 will be described in detail together with the first fitted portion 74.

[0075] The main body member 61 is provided with a cover 67. The cover 67 protrudes in the X direction from the other end surface of the housing main body 62. The cover 67 surrounds the periphery of the conductor pin of the male terminal. The cover 67 can be omitted from the connector housing 60. For example, in a case where the connector housing 60 accommodates a female terminal, the cover 67 can be omitted.

[0076] The main body member 61 is provided with a vehicle fitting portion 68. The vehicle fitting portion 68 is provided in a manner of protruding outward from the side surface of the housing main body 62. The vehicle fitting portion 68 is a portion for fitting the connector housing 60 to a vehicle. A mounting hole 68h is formed in the vehicle fitting portion 68. A bolt or the like is inserted in the mounting hole 68h to fit the vehicle fitting portion 68 to the vehicle. A metal ring or the like can be provided in the mounting hole 68h. The vehicle fitting portion 68 can be omitted from the connector housing 60.

[0077] In addition, the main body member 61 is provided with a seal member mounting portion 69. The seal member mounting portion 69 is provided in a manner of annularly recessing a portion of the side surface of the housing main body 62. The seal member mounting portion 69 is provided on one side with respect to the vehicle fitting portion 68. An O-ring or the like seal member S is mounted in the seal member mounting portion 69. The seal member mounting portion 69 can be omitted from the connector housing 60.

[0078] The cover members 70, 80 are mounted to the main body member 61. Here, the cover members 70 include the first cover member 70 and the second cover member 80.

[0079] The first cover member 70 is attached to the main body member 61. The first cover member 70 is attachable to the main body member 61 in a state in which the rear end portion of the terminal member 30 protrudes outside the cavity 63, with a sliding movement in a direction (here, the Z direction) intersecting the length direction (here, the X direction) of the cavity 63. The first cover member 70 includes a first wall portion 71 and a first connecting wall portion 73. Here, the first cover member 70 further includes a first fitting portion 74 and second fitting portions 75 and 76.

Here, the first wall portion 71 covers the rear end portion of the terminal member 30 from both sides in the Y direction. The first wall portion 71 is formed in a flat plate shape extending along the XZ plane. Here, the cavity 63 is provided in five rows, and therefore the first wall portion 71 is provided in six. Four of the six first wall portions 71a are provided between the five rows of cavities 63. The four first wall portions 71a separate the rows of cavities 63. The thickness dimension of the four first wall portions 71a is the same as the thickness dimension of the protruding wall portion 64, and is the same order as the dimension of the gap between two cavities 63. Two of the six first wall portions 71b are provided outside the five rows of cavities 63. The two first wall portions 71b surround the cavities 63.

[0081] A slit 72 is formed in the first wall portion 71. The slit 72 extends from the end surface of the first wall portion 71 on the negative side in the X direction toward the positive side in the X direction. The slit 72 does not reach the end surface of the first wall portion 71 on the positive side in the X direction. The slit 72 is provided between the cavities 63 arranged in the layer direction. The slit 72 is provided at a position corresponding to the protruding wall portion 64. The second wall portion 81 described later passes through the slit 72. The dimension along the X direction from the end surface of the first wall portion 71 on the positive side in the X direction to the tip of the slit 72 is the same order as the dimension of the protruding wall portion 64.

[0082] The first connecting wall portion 73 connects the plurality of (here, six) first wall portions 71. The first connecting wall portion 73 is formed in a flat plate shape extending along the XY plane. The end surface of the first wall portion 71 on the positive side in the Z direction is connected to the surface of the first connecting wall portion 73 facing the negative side in the Z direction. The first wall portion 71 protrudes toward the negative side in the Z direction from the surface of the first connecting wall portion 73 facing the negative side in the Z direction. Here, the slit 72 is not formed in the first connecting wall portion 73. Here, the first connecting wall portion 73 covers the rear end portion of the terminal member 30 inserted into the cavity 63 of the first layer (the uppermost layer) from the Z direction. Figure 4

[0083] ​The first engaged portion 74 is engaged with the first engagement portion 66. The first engagement portion 66 and the first engaged portion 74 maintain the attached state of the main body portion and the first cover member 70. The first engagement portion 66 and the first engaged portion 74 are engaged in a direction (here, the Z direction) in which the main body member 61 and the first cover member 70 are slidably moved in a direction (here, the X direction) intersecting the length direction of the cavity 63.

[0084] More specifically, the first engaged portion 74 is provided on the outer side of each of the two first wall portions 71. The first engaged portion 74 is provided on the end surface side of the first wall portion 71 on which the slit 72 is not formed. The first engaged portion 74 is provided in a cuboid shape long in the Z direction.

[0085] The first engagement portion 66 has a protruding piece 66a and a protruding portion 66b. The protruding piece 66a protrudes in the Z direction from the end portion of the protruding frame portion 65 while being spaced apart from one end surface of the housing main body 62. The protruding piece 66a is provided in a cantilever beam shape. The protruding portion 66b is provided in the one end surface of the housing main body 62 opposite the protruding piece 66a. The protruding portion 66b protrudes in the X direction toward the protruding piece 66a. The first engaged portion 74 is inserted between the protruding piece 66a and the protruding portion 66b. The surface (surface facing the positive side in the Z direction) of the protruding portion 66b and the protruding piece 66a on which the first engaged portion 74 is inserted is provided with a guide surface.

[0086] The protruding portion 66b is formed in a shape in which a portion including one corner is cut out in a cuboid shape corresponding to the shape of the first engaged portion 74. The one corner is a corner of the protruding portion 66b on the negative side in the Z direction and located on the center side of the housing main body 62 in the Y direction. The portion of the protruding portion 66b that is cut out accommodates the first engaged portion 74. A step portion 66c is formed with respect to a portion of the protruding portion 66b that is cut out, the portion remaining on the positive side in the Z direction. The step portion 66c presses the rear of the first engaged portion 74 inserted into the first engagement portion 66. Thus, the first cover member 70 can be inhibited from falling out on the positive side in the Z direction with respect to the main body member 61. The front of the first engaged portion 74 inserted into the first engagement portion 66 is pressed by the protruding frame portion 65.

[0087] A step portion 66d is formed with respect to a portion of the protruding portion 66b that is cut out, the portion remaining on the outer side of the housing main body 62 in the Y direction. The step portion 66d presses the side of the first engaged portion 74 inserted into the first engagement portion 66. Thus, the first cover member 70 and the main body member 61 are positioned in the Y direction.

[0088] The protruding frame portion 65 of the main body member 61 and the wall portion of the first cover member 70 contact in the Y direction and the Z direction. Thus, the first cover member 70 and the main body member 61 are positioned in the Y direction, and the first cover member 70 can be inhibited from falling out on the negative side in the Z direction with respect to the main body member 61.

[0089] The second fitting portions 75, 76 are fitted to second fitted portions 83 provided to the second cover member 80. Details of the second fitting portions 75, 76 will be described later together with the second fitted portions 83.

[0090] The second cover member 80 is attached to the first cover member 70. Therefore, the second cover member 80 is attached to the main body member 61 through the first cover member 70. The first cover member 70 and the second cover member 80 are attachable to the main body member 61 in a state where the rear end portions of the terminal members 30 inserted into the cavities 63 protrude outside the cavities 63, and are slidable in directions crossing the main body member 61 (here, the Y direction). The second cover member 80 has a second wall portion 81 and a second connecting wall portion 82. Here, the second cover member 80 further includes second fitted portions 83. Here, the second cover member 80 further includes an electric wire restriction portion 84. The second cover member 80 is formed of a resin or the like having insulating properties. The second cover member 80 is, for example, an injection molded product.

[0091] The second wall portion 81 covers another portion of the rear end portions of the terminal members 30 along the circumferential direction. Here, the second wall portion 81 covers the rear end portions of the terminal members 30 from the Z direction. The second wall portion 81 is formed in a flat plate shape extending along the XY plane. Six of the second wall portions 81 are provided. Four of the six second wall portions 81a are provided between the four layers of the cavities 63. Here, the cavities 63 are four layers, but the second layer and the third layer are wider, and therefore two of the second wall portions 81a are provided therebetween. The four second wall portions 81a are inserted into the slits 72. The four second wall portions 81a separate the layers of the plurality of cavities 63. The thickness dimension of the four second wall portions 81a is the same as the thickness dimension of the protruding wall portion 64, and is the same degree as the dimension of the gap between two of the cavities 63. Two of the six second wall portions 81b are provided outside the four layers of the cavities 63. The two second wall portions 81b surround the plurality of cavities 63. Further, here, the two second wall portions 81b surround the first cover member 70. One of the two second wall portions 81b is provided outside the first connecting wall portion 73. Therefore, one of the two second wall portions 81b does not face the terminal members 30.

[0092] The second connecting wall portion 82 connects the six second wall portions 81. The second connecting wall portion 82 is formed in a curved plate shape corresponding to one end surface of the housing main body 62. The second wall portion 81 and the second connecting wall portion 82 are located on the X direction negative side from the protruding frame portion 65.

[0093] Two second-to-be-engaged portions 83 are provided. The two second-to-be-engaged portions 83 are engaged with the second engaged portions 75, 76, respectively. The second engaged portions 75, 76 and the second-to-be-engaged portions 83 maintain the mounted state of the first cover member 70 and the second cover member 80. The second engaged portions 75, 76 and the second-to-be-engaged portions 83 are engaged in a direction in which the first cover member 70 and the second cover member 80 are slidably moved in a direction (here, the Y direction) intersecting the length direction of the cavity 63.

[0094] More specifically, the second-to-be-engaged portions 83 are provided on the inner sides of the two second wall portions 81b. A part of the two second wall portions 81b protrudes outward in the Z direction. A groove 83a is formed on the inner side of the protruding part. The groove 83a extends in the Y direction. An engagement hole 83b is formed at the end of the groove 83a.

[0095] The second engaged portion 75 is provided on the outer surface of the first connecting wall portion 73. The second engaged portion 75 has a protruding portion 75a and an anti-extraction piece 75b. The protruding portion 75a is formed in a cuboid shape long in the Y direction. The protruding portion 75a extends from the end surface of the first connecting wall portion 73 on the negative side in the Y direction to the middle portion in the Y direction. The anti-extraction piece 75b is provided on the tip of the protruding portion 75a. The anti-extraction piece 75b protrudes more in the Z direction than the protruding portion 75a.

[0096] The second engaged portion 76 is provided on the end surface of the first wall portion 71 on the negative side in the Z direction. The second engaged portion 76 has four protruding portions 76a protruding from the four first wall portions 71, respectively, and an anti-extraction piece 76b provided on one of the four protruding portions 76a. The second engaged portion 76 is formed in a shape in which a part between the second engaged portion 75 and the first wall portion 71 is cut.

[0097] The second engaged portions 75, 76 are inserted into the second-to-be-engaged portions 83 along the grooves 83a. The anti-extraction pieces 75b, 76b are engaged with the peripheral portions of the engagement holes 83b by passing through the engagement holes 83b, whereby the second engaged portions 75, 76 and the second-to-be-engaged portions 83 are engaged.

[0098] The electric wire restriction portion 84 restricts the path of the covered electric wire 22 extending outward from the accommodation space. Here, the electric wire restriction portion 84 bends the covered electric wire 22 extending from the accommodation space toward the negative side in the X direction toward the negative side in the Y direction. Specifically, the electric wire restriction portion 84 has a guide portion 84a and a restriction portion 84b. The guide portion 84a is formed so as to slope from the two second wall portions 81b and the second connecting wall portion 82 toward the restriction portion 84b. The guide portion 84a is formed so as to gradually decrease in cross section. The covered electric wire 22 extending from the accommodation space in a loose state in the Z direction is gathered in the Z direction by the guide portion 84a. The restriction portion 84b is formed in a frame shape with the portion connected to the guide portion 84a and the portion opening toward the negative side in the Y direction. The restriction portion 84b covers the negative side in the X direction of the covered electric wire 22. Thus, the covered electric wire 22 is bent toward the negative side in the Y direction. The electric wire restriction portion 84 can not be provided in the connector housing 60.

[0099] <Method for manufacturing electric wire with connector>

[0100] When the electric wire with connector 10 is manufactured, the electric wire with terminal 20 and the connector housing 60 in the exploded state are prepared first. Then, the electric wire with terminal 20 is inserted into the main body member 61. At this time, since the length dimension of the cavity 63 of the main body member 61 is shorter than the length dimension of the terminal member 30, the insertion amount of the electric wire with terminal 20 into the cavity 63 can be short. In addition, the terminal member 30 can be held outside the one opening portion of the cavity 63 and in the portion where the protruding wall portion 64 is not provided, and the electric wire with terminal 20 can be inserted into the cavity 63. Thus, when inserted into the cavity 63, the electric wire with terminal 20 is difficult to be bent even if it comes into contact with the inner surface of the cavity 63. In addition, the position near the one opening portion in the cavity 63 has a portion that accommodates the sealing member 50, and thus the movement amount of the sealing member 50 in the cavity 63 can be small. Thus, the insertion of the electric wire with terminal 20 into the cavity 63 becomes easy.

[0101] When the main body member 61 is inserted into the electric wire with terminal 20, as shown in Figure 6 and Figure 7 the first cover member 70 is attached to the main body member 61. Figure 6 and Figure 7 are explanatory diagrams showing the case where the first cover member 70 is attached to the main body member 61. Figure 6 is a cross-sectional view, Figure 7 is a front view.

[0102] The first cover member 70 is attached to the main body member 61 so as to be slidable in the Z direction. Here, four first wall portions 71 are inserted between the terminal members 30 and the protruding wall portion 64 arranged in the column direction. In addition, two first wall portions 71 are inserted between the protruding frame portion 65 and the protruding wall portion 64 and the terminal members 30. In addition, the first fitting portion 74 is fitted to the first fitting portion 66. At this time, the first cover member 70 is slid so as to abut the end surface of the X direction positive side of the first cover member 70 to the one end surface of the housing main body 62, whereby the first cover member 70 is attached to the main body member 61. In addition, at this time, the insertion of the first wall portions 71 is performed prior to the insertion of the first fitting portion 74, whereby the direction alignment of the fitting of the main body member 61 and the first cover member 70 is performed. Thus, the main body member 61 and the first cover member 70 are easily attached.

[0103] When the first cover member 70 is attached to the main body member 61, as shown in Figure 8 and Figure 9 the second cover member 80 is attached to the first cover member 70. Figure 8 and Figure 9 are explanatory diagrams showing the case where the second cover member 80 is attached to the first cover member 70. Figure 8 is a sectional view, Figure 9 is a front view.

[0104] The second cover member 80 is attached to the first cover member 70 attached to the main body member 61 so as to be slidable in the Y direction. Here, four second wall portions 81 are inserted into the slits 72. Four second wall portions 81 are inserted between the terminal members 30 arranged in the layer direction. In addition, the first cover member 70 is inserted between two second wall portions 81. In addition, the second fitting portions 75, 76 are fitted to the second fitting portions 83. At this time, the second cover member 80 is slid so as to abut the end surface of the X direction positive side of the second cover member 80 to the end surface of the X direction negative side of the protruding frame portion 65, whereby the second cover member 80 is attached to the first cover member 70. In addition, at this time, the insertion of the second wall portions 81 is performed prior to the insertion of the second fitting portions 75, 76, whereby the direction alignment of the fitting of the first cover member 70 and the second cover member 80 is performed. Thus, the first cover member 70 and the second cover member 80 are easily attached.

[0105] By attaching the first cover member 70 and the second cover member 80 to the main body member 61, the periphery of the rear end portion of the terminal member 30 is covered by four wall portions. The four wall portions are combined to form a quadrangular cylindrical shape. That is, the cross-sectional shape of the space surrounded by the four wall portions is a quadrangle. Here, the combination of the four wall portions covering the rear end portion of the terminal member 30 differs depending on the position of the cavity 63 into which the terminal member 30 is inserted, the position of the protrusion of the terminal member 30 from the cavity 63, and the like.

[0106] In more detail, the portion of the rear end portion of the terminal member 30 inserted into the cavity 63 of the uppermost layer of the first layer (1) near the cavity 63 is covered all around by two first wall portions 71, one protruding wall portion 64, and one first connecting wall portion 73. The portion of the rear end portion of the terminal member 30 inserted into the cavity 63 of the first layer far from the cavity 63 is covered all around by two first wall portions 71, one second wall portion 81, and one first connecting wall portion 73. Figure 9

[0107] The portion of the rear end portion of the terminal member 30 inserted into the cavity 63 of the second and third layers (the second layer and the third layer from the top) is covered all around by two first wall portions 71 and two protruding wall portions 64. The portion of the rear end portion of the terminal member 30 inserted into the cavity 63 of the second and third layers far from the cavity 63 is covered all around by two first wall portions 71 and two second wall portions 81. Figure 9

[0108] The portion of the rear end portion of the terminal member 30 inserted into the cavity 63 of the fourth layer (the lowermost layer of the fourth layer) near the cavity 63 is covered all around by two first wall portions 71, one protruding wall portion 64, and one protruding frame portion 65. The portion of the rear end portion of the terminal member 30 inserted into the cavity 63 of the fourth layer far from the cavity 63 is covered all around by two first wall portions 71 and two second wall portions 81. Figure 9

[0109] <Effects, etc. of Embodiment 1>

[0110] According to the electric wire 10 with the connector configured as described above, by inserting the terminal member 30 into the cavity 63 of the main body member 61 before the cover member 70, 80 is attached, the amount of insertion of the terminal member 30 into the cavity 63 is reduced. By attaching the cover member 70, 80 to the main body member 61 after the terminal member 30 is inserted into the cavity 63, the rear end portion of the terminal member 30 is covered. Thus, the electric wire 20 with the terminal can be easily housed in the connector housing 60.

[0111] In addition, the entire circumference of the rear end portion of the terminal member 30 can be covered by the first wall portion 71 provided to the first cover member 70 and the second wall portion 81 provided to the second cover member 80. Thus, the entire circumference of the rear end portion of the terminal member 30 can be covered by the two cover members 70, 80 attached to the main body member 61.

[0112] ​​​Further, the first fitting portion 66 and the first fitted portion 74 are fitted in a direction in which the main body member 61 and the first cover member 70 are slid in a direction intersecting the length direction of the cavity 63. Thus, the first fitting portion 66 and the first fitted portion 74 are fitted when the main body member 61 and the first cover member 70 are slid in the direction intersecting the length direction of the cavity 63. Similarly, the second fitting portions 75, 76 and the second fitted portion 83 are fitted in a direction in which the first cover member 70 and the second cover member 80 are slid in a direction intersecting the length direction of the cavity 63. Thus, the second fitting portions 75, 76 and the second fitted portion 83 are fitted when the first cover member 70 and the second cover member 80 are slid in the direction intersecting the length direction of the cavity 63.

[0113] The sealing member 50 is disposed inside the cavity 63, and the portion of the terminal member 30, which is behind the portion where the sealing member 50 is installed, protrudes outward from the cavity 63. Thus, the amount of movement of the sealing member 50 inside the cavity 63 is reduced. Thus, the electric wire 20 with the terminal can be easily accommodated in the connector housing 60.

[0114] Further, the portion of the cavity 63 where the sealing member 50 is disposed has a circular cross-sectional shape. Thus, the sealing member 50 and the inner surface of the cavity 63 easily fit together. Further, the four wall portions that cover the rear end portion of the terminal member 30 are integrated to form a square tube shape. Thus, the shape of the wall portions that cover the rear end portion of the terminal member 30 becomes a simple shape.

[0115] [Embodiment 2]

[0116] The connector housing of Embodiment 2 will be described. Figure 10 is an exploded perspective view showing the connector housing 160 of Embodiment 2. Figure 11 is an explanatory view showing a case where the cover member 80 is installed in the main body member 161. Further, in the following description, the same reference numerals are attached to the same constituent elements as those described so far, and the description thereof will be omitted.

[0117] The connector housing 160 includes the main body member 161 and the cover member 80. In the connector housing 160, the rear end portion of the terminal member 30 also protrudes outward from the cavity 63 of the main body member 161. Further, the rear end portion of the terminal member 30 is covered by the first wall portion 171 and the second wall portion 81. The first wall portion 171 covers a portion of the rear end portion of the terminal member 30 along the circumferential direction, and the second wall portion 81 covers another portion of the rear end portion of the terminal member 30 along the circumferential direction. The connector housing 160 is different from the above-described connector housing 60 in that the cover member 80 is one. Because the cover member 80 is one, the first wall portion 171 is provided to the main body member 161. The second wall portion 81 is provided to the cover member 80.

[0118] Further, inFigure 10 , Figure 11 In the example shown, the main body component 161 is formed with some structures omitted (e.g., protruding wall portion 64, protruding frame portion 65, first fitting portion 66, and first fitted portion 74, etc.) or with some structures added, from the shape of the main body component 61 and the first cover component 70 combined in Embodiment 1. The cover component 80 is the same as the second cover component 80 described above. Therefore, the first wall portion 171 in the main body component 161 in this example is formed with a shape corresponding to the first wall portion 71 in the first cover component 70 described above. The second wall portion 81 in the cover component 80 in this example is the same as the second wall portion 81 in the second cover component 80 described above.

[0119] like Figure 11 As shown, with the rear end of the terminal component 30 protruding outside the cavity 63, the cover component 80 can be mounted on the main body component 161 by sliding in a direction (Y direction) intersecting the length direction (X direction) of the cavity 63. Thus, by mounting a cover component 80 on the main body component 161, the entire circumference of the rear end portion of the terminal component 30 can be covered by the main body component 161 and the cover component 80. Furthermore, the main body component 161 and the cover component 80 are engaged by the fitting portion 175 and the fitted portion 83.

[0120] More specifically, the main body component 161 is provided with a first wall portion 171, a first connecting wall portion 173, and a fitting portion 175. The first wall portion 171 and the first connecting wall portion 173 protrude from the end face of one of the openings where the cavity 63 is formed. The cavities 63 in the main body component 161 are arranged in a manner similar to that in Embodiment 1, in four layers and five columns. The first wall portion 171 is formed in a configuration such as being divided by reaching the other end face of the first wall portion 71 through a slit 72 formed in the first wall portion 71. That is, the first wall portion 171 covers both sides of each cavity 63 in the Y direction. Six first wall portions 171 are provided in each layer. The first wall portions 171 of adjacent layers are separated from each other in the Y direction.

[0121] Two first connecting wall portions 173 are provided. The two first connecting wall portions 173 are formed with the same shape as the first connecting wall portion 73 in the first cover member 70 described above. One of the two first connecting wall portions 173, like the first connecting wall portion 73, is located in the first layer ( Figure 11 The outer side of cavity 63 in the uppermost layer. The first connecting wall portion 173 connects six first wall portions 171 disposed adjacent to cavity 63 in the first layer. Another first connecting wall portion 173 is located in the fourth layer ( Figure 11 The outer side of cavity 63 (the lowest layer). The first connecting wall 173 connects the six first wall portions 171 that are disposed adjacent to cavity 63 of the fourth layer.

[0122] Two of the fitting portions 175 are provided. The two fitting portions 175 are provided on the outer side of the first connecting wall portion 173. The two fitting portions 175 are formed in the same shape as the second fitting portion 75 described above. One of the two fitting portions 175 is formed at the same position as the second fitting portion 75 described above. The other of the two fitting portions 175 is formed at the same position as the second fitting portion 76 described above. Therefore, the second fitting portion 76 described above is omitted, and the fitting portion 175 is provided instead.

[0123] By mounting the cover member 80 to the main body member 161, the periphery of the rear end portion of the terminal member 30 is covered by four wall portions. The four wall portions are combined to form a square cylindrical shape. That is, the cross-sectional shape of the space surrounded by the four wall portions is a square shape. Here, the combination of the four wall portions covering the rear end portion of the terminal member 30 differs depending on the position of the cavity 63 into which the terminal member 30 is inserted.

[0124] More specifically, the rear end portion of the terminal member 30 inserted into the cavities 63 of the uppermost layer of the first layer (the first layer) and the lowermost layer of the fourth layer (the fourth layer) is covered all around by two first wall portions 171, one second wall portion 81, and one first connecting wall portion 173. The rear end portion of the terminal member 30 inserted into the cavities 63 of the second layer and the third layer (the second layer and the third layer from the top of the Figure 11 Figure 11 Figure 11

[0125] [Modified Example]

[0126] Figure 12 is an exploded perspective view showing a modified example of the connector housing. In Embodiment 1, it is assumed that the first fitting portion 66 and the first fitted portion 74 are fitted in a direction in which the main body member 61 and the first cover member 70 are slid in a direction intersecting the length direction of the cavity 63, but this is not a necessary structure. As Figure 12 shown in FIG. 17, the first fitting portion and the first fitted portion can also be configured to be fitted in the length direction of the cavity 63.

[0127] In the connector housing 260 shown in FIG. 18, the first fitting portion 266 of the main body member 261 and the first fitted portion 274 of the first cover member 270 are fitted in the length direction of the cavity 263 (the X direction in Figure 12 Figure 12 Figure 12 ​​​​​The first wall portion 271 of the first cover member 270 is inserted between the terminal members 30 protruding from the cavity 263 by moving in the Z direction (the direction orthogonal to the X direction and the Y direction). Then, the first cover member 270 is moved in the X direction with respect to the main body member 261, and the first fitting portion 266 and the first fitted portion 274 are fitted.

[0128] The first cover member 270 and the second cover member 280 are installed similarly to the first cover member 70 and the second cover member 80 described above. That is, the first cover member 270 and the second cover member 280 are slid in the Y direction, and the second wall portion 281 is inserted into the slit 272 formed in the first wall portion 271. In addition, the first cover member 270 and the second cover member 280 are slid in the Y direction, and the second fitting portion 275 and the second fitted portion 283 are fitted. The first cover member and the second cover member can also be configured to be fitted in the length direction of the cavity 263. In addition, in the case where the cover member is one as in Embodiment 2, the main body member and the cover member can also be configured to be fitted in the length direction of the cavity.

[0129] Further, in the connector housing 260, a seal member mounting portion 277 is provided in the first cover member 270. The seal member mounting portion 277 is also formed in the first wall portion 271. The first cover member 270 is a member that is inserted between the rear end portions of the terminal members 30 protruding from the cavity 263, and thus it is difficult to form a shape that is completely annular around the X axis. Therefore, the seal member mounting portion 277 is interrupted in the circumferential direction between the first wall portion 271.

[0130] In addition to this, the description has been made so far on the assumption that the terminal member 30 includes the junction terminal 32, the connector terminal 40, and the relay conductor 46, but this is not necessarily the structure. Either one or both of the junction terminal 32 and the relay conductor 46 can be omitted. In the case where either one or both of the junction terminal 32 and the relay conductor 46 is omitted, the wire connecting portion 33 is provided to the remaining terminal member 30. In addition, the mounting portion 48 is provided to the remaining terminal member 30 or the conductor core wire 24.

[0131] More specifically, in the case where both of the junction terminal 32 and the relay conductor 46 are omitted, the wire connecting portion is provided to the connector terminal. The mounting portion can be provided to the connector terminal or to the conductor core wire 24. In the case where the mounting portion is provided to the connector terminal, the mounting portion is preferably formed in a ring shape like a barrel, and a portion of the mounting portion on the side of the wire connecting portion side is closed. In the case where the mounting portion is provided to the conductor core wire 24, the conductor core wire 24 is preferably a single core wire composed of one conductor, and the seal member 50 is mounted to the conductor core wire 24 in such a manner that the seal body is located between the insulating covering portion 26 and the connector terminal.

[0132] If either the connector terminal 32 or the relay conductor 46 is omitted, the function of one is integrated with the other. For example, the function of the connector terminal 32 can also be integrated with the relay conductor. In this case, a wire connection portion is provided in the relay conductor.

[0133] Alternatively, the sealing member 50 can be omitted from the wire 20 with terminals. Furthermore, the inner surface of the cavity 63 may not be circular. The inner surface of the cavity 63 may also be rectangular, etc.

[0134] In addition, such as Figure 7 As shown, in the main body component 61, a protruding wall portion 64 is formed in one opening of the cavity 63 in the height direction of the terminal component 30. Therefore, in the main body component 61, the terminal component 30 is open in the left-right direction relative to one opening of the cavity 63. Furthermore, in the terminal component 30, the height direction is the direction in which the crimping tabs protrude from the bottom of each cylinder, which is the Z direction in each figure. Additionally, in the terminal component 30, the left-right direction is the direction in which the base ends of a pair of crimping tabs in each cylinder are arranged, which is the Y direction in each figure. Figure 11 As shown, in the main body component 161, a first wall portion 171 is formed in one opening of the cavity 63 in the left-right direction of the terminal component 30. Therefore, in the main body component 161, the terminal component 30 is open in the height direction relative to one opening of the cavity 63. The protruding wall portion 64 of the main body component 61 may also be formed in the cavity 63 in the left-right direction of the terminal component 30, just like the first wall portion 171 of the main body component 161, leaving the terminal component 30 open in the height direction. Alternatively, the first wall portion 171 of the main body component 161 may also be formed in the cavity 63 in the height direction of the terminal component 30, just like the protruding wall portion 64 of the main body component 61, leaving the terminal component 30 open in the left-right direction.

[0135] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
