[0027] <Explanation of Embodiments of the Present Disclosure>

[0028] First, an embodiment of the present disclosure will be explained.

[0029] The connector unit of the present disclosure,

[0030] (1) has: a connector having a terminal connected to a terminal portion of an electric wire and a housing that holds the terminal; and a cylindrical connector cover composed of an elastic material that covers the housing, the connector cover having a ring-shaped sealing portion provided at a position that can contact a surface on the counterpart connector side in a fitted state with the counterpart connector.

[0031] According to the connector unit of the present disclosure, the ring-shaped sealing portion of the connector cover is provided at a position that can contact a surface on the counterpart connector side in a fitted state with the counterpart connector. That is, by the ring-shaped sealing member of the connector cover provided at the outermost circumference of the connector unit contacting the surface on the counterpart connector side, a gap between the connector cover and the surface on the counterpart connector side is sealed. As a result, waterproofness of the connector unit on the fitting side with the counterpart connector can be improved. In addition, by the ring-shaped sealing portion of the connector cover, entry of foreign matter such as mud attached to the periphery of the connector cover into the connector cover is advantageously prevented during use. Therefore, entry of foreign matter into the housing when the connector unit is inserted into or pulled out from the counterpart connector at the time of maintenance or the like can be suppressed. Thus, occurrence of adverse conditions that adversely affect re-fitting of the connector unit and the counterpart connector can be suppressed or reduced.

[0032] (2) Preferably, the ring-shaped sealing portion has a shape that expands in diameter toward the counterpart connector side and protrudes in a taper shape. Since the ring-shaped sealing portion has a shape that protrudes in a taper shape, when contacting the surface on the counterpart connector side, the tip end portion of the ring-shaped sealing portion can contact the surface while expanding in a direction away from the central axis of the ring-shaped sealing portion. As a result, the contact area of the surface on the counterpart connector side can be advantageously increased, and the sealing property of the ring-shaped sealing portion can be improved.

[0033] ​(3) Preferably, the connector cover has a positioning portion that performs positioning of the connector cover with respect to the housing, and the positioning is performed by contact with the housing. This is because: by contact of the positioning portion of the connector cover with the housing, assembly of the housing and the connector cover in a normal position can be easily achieved. In a fitted state to the counterpart connector, contact of the annular seal portion to the surface of the counterpart connector side can be favorably and easily achieved.

[0034] (4) Preferably, the connector has a connector position assurance member that assures normal fitting to the counterpart connector, the connector cover has an opening window that exposes the connector position assurance member to the outside of the connector cover, and a cover portion that covers the opening window openably. The connector cover that covers the housing has an opening window that exposes the connector position assurance member to the outside of the connector cover. Thereby, even in a state where the connector cover is attached to the connector, the connector position assurance member provided to the housing can be visually confirmed through the opening window of the connector cover. Also, the connector cover can maintain the waterproofness and the like protection function of the connector cover as a whole because the cover portion covers the opening window.

[0035] (5) Preferably, the opening window has a protruding portion provided to an inner peripheral surface, the cover portion has a recessed portion provided to an outer peripheral surface that contacts the inner peripheral surface, the protruding portion protrudes toward the outer peripheral surface, and the recessed portion receives the protruding portion in a close contact state. By close contact of the protruding portion and the recessed portion, the sealing property between the contact surfaces of the cover portion and the opening window is improved, and improvement of the waterproof function of the connector cover can be achieved. Further, unintended detachment of the cover portion from the opening window can be suppressed.

[0036] (6) Preferably, the connector cover has a first end portion and a second end portion located on the opposite side of the first end portion, the first end portion has the annular seal portion, the second end portion of the connector cover has a wire penetrating cylinder portion through which the electric wire connected to the terminal penetrates, and an inner surface of the wire penetrating cylinder portion is in close contact with an outer surface of the electric wire. The waterproofness of the first end portion side of the connector cover is assured by the annular seal portion, and the waterproofness of the second end portion side of the connector cover is assured by close contact of the inner surface of the wire penetrating cylinder portion with the outer surface of the electric wire. Thereby, further improvement of the waterproofness of the connector cover can be achieved.

[0037] (7) Preferably, the housing holds a plurality of the terminals, the electric wires are a plurality of electric wires, the plurality of electric wires are connected to the plurality of terminals, the electric wire penetration cylinder portion is penetrated by the electric wires, the electric wire penetration cylinder portion has a partition wall, the partition wall is provided to the inner surface and is located between the plurality of electric wires, the partition wall has a protruding end portion that is separable from the inner surface, and the partition wall defines a penetration region of each of the electric wires that is in close contact with the outer surface of each of the electric wires. The electric wire penetration cylinder portion has a partition wall that is provided to the inner surface and is located between the plurality of electric wires, and the partition wall defines a penetration region of each of the electric wires that is in close contact with the outer surface of each of the electric wires. Thus, interference between the plurality of electric wires can be suppressed. Here, the "interference" means that the electric wires contact each other. In addition, each of the electric wires is stably held to the electric wire penetration cylinder portion. Furthermore, the gap between the electric wires is closed by the partition wall located between the electric wires, and thus the waterproofness between the electric wires (which is a problem when the plurality of electric wires is penetrated into the electric wire penetration cylinder portion) is improved. Further, the protruding end portion of the partition wall is separable from the inner surface of the electric wire penetration cylinder portion. Thus, when the plurality of electric wires is penetrated into the electric wire penetration cylinder portion, the electric wire penetration cylinder portion can be handled as an electric wire penetration cylinder portion having a single electric wire penetration hole. Thus, the penetration work of each of the electric wires into each of the electric wire penetration regions is easy.

[0038] (8) Preferably, further having a fastening member that is fixed to the electric wire penetration cylinder portion and that brings the inner surface of the electric wire penetration cylinder portion into contact with the outer surface of the electric wire. The inner surface of the electric wire penetration cylinder portion is brought into close contact with the outer surface of the electric wire by the fastening member, and thus the waterproofness of the electric wire penetration cylinder portion can be further improved.

[0039] The wire harness of the present disclosure,

[0040] (9) A connector unit and an electric wire connected to a terminal of the connector unit, the connector unit including: a connector having the terminal connected to a terminal portion of the electric wire and a housing holding the terminal; and a cylindrical connector cover made of an elastic material, covering the housing, the connector cover having a ring-shaped seal portion provided at a position that can come into contact with a surface of a counterpart connector on the counterpart connector side in a fitted state in which the connector is fitted to the counterpart connector.

[0041] According to the wire harness of the present disclosure, the wire harness having the connector unit described in (1) above can be provided, and the same effects as the connector unit described in (1) above can be achieved.

[0042] The connector fitting structure of the present disclosure,

[0043] (10) The connector unit of at least one of (1) to (8) described above, and the counterpart connector that is fitted to the connector unit, the annular seal portion of the connector unit being in contact with the surface on the side of the counterpart connector in the fitted state of the connector unit to the counterpart connector.

[0044] According to the connector fitting structure of the present disclosure, in the connector fitting structure of the connector unit provided with the connector unit described in (1) to (8) above and the counterpart connector fitted to the connector unit, the annular seal portion of the connector unit is in contact with the surface on the side of the counterpart connector in the fitted state of the connector unit to the counterpart connector. Thus, the waterproof property of the vicinity of the fitting portion of the connector unit and the counterpart connector can be improved. In addition, by the annular seal portion of the connector cover of the connector unit, entry of foreign matter such as mud attached to the periphery of the connector cover into the connector cover is advantageously prevented in use. Thus, entry of foreign matter into the housing of the connector unit to adversely affect the re-fitting of the connector unit and the counterpart connector can be suppressed or reduced when the connector unit is inserted into or pulled out from the counterpart connector at the time of maintenance or the like.

[0045] <Details of Embodiments of the Present Disclosure>

[0046] Specific examples of the connector unit, the wire harness, and the connector fitting structure of the present disclosure will be described below with reference to the accompanying drawings. Figure 1

[0047] <Embodiment 1>

[0048] Hereinafter, Embodiment 1 of the present disclosure will be described with reference to the accompanying drawings. Figures 1 to 11 Figure 1 A perspective view showing a state in which the connector unit 10 of Embodiment 1 of the present disclosure is assembled with the counterpart connector 12 is shown in FIG. 1. The counterpart connector 12 assembled with the connector unit 10 is fixed to a case or the like of an inverter or the like electrical equipment, not shown. In addition, in the drawings, the X-axis direction among the X, Y, and Z axes represents the length direction of the connector unit 10, the Y-axis direction represents the width direction of the connector unit 10, and the Z-axis direction represents the up-down direction. In addition, with respect to a plurality of identical members, only a part of the members in the drawings are sometimes provided with reference numerals, and the reference numerals are omitted for the other members.

[0049] <Counterpart Connector 12>

[0050] As shown in FIG. 2, the counterpart connector 12 is provided with a counterpart connector housing 14. The counterpart connector housing 14 is made of synthetic resin. As shown in FIG. 3, the counterpart connector housing 14 is provided with a counterpart connector cover 16. The counterpart connector cover 16 is made of synthetic resin. The counterpart connector cover 16 is fitted to the counterpart connector housing 14. The counterpart connector cover 16 is provided with a counterpart connector cover housing 18. The counterpart connector cover housing 18 is made of synthetic resin. The counterpart connector cover housing 18 is provided with a counterpart connector cover housing annular seal portion 20. The counterpart connector cover housing annular seal portion 20 is made of rubber. The counterpart connector cover housing annular seal portion 20 is in contact with the connector unit 10 in the fitted state of the connector unit 10 to the counterpart connector 12. Figure 2 Figure 2 ​​​As shown, the counterpart connector housing 14 has a rectangular shape and is configured with openings at the front (one side of the X-axis direction) and rear (the other side of the X-axis direction) along its length. Here, the length direction (X-axis direction in the figure) refers to the mounting and dismounting direction of the connector unit 10 relative to the counterpart connector 12. More specifically, the front direction along the length is the direction in which the connector unit 10 moves when it is engaged with the counterpart connector 12. A fixing portion 18 is formed on the front side of the counterpart connector housing 14. The fixing portion 18 protrudes outward from the periphery of the front opening 16 in a direction orthogonal to the central axis of the counterpart connector housing 14 in a flange-like manner. The fixing portion 18 is rectangular flat in a frontal view from the front side along the length direction. At the four corners of the fixing portion 18, through holes 20 with a circular cross-section are provided in the thickness direction. The counterpart connector housing 14 is fixed to the housing of an electrical device (not shown) by bolts passing through the through holes 20 of the fixing portion 18. Additionally, the annular rubber seal 24 is fitted onto the front surface 22 of the fixing part 18, contacting the enclosure and shielding components of the electrical equipment (not shown). This prevents water, dust, and other contaminants from penetrating the electrical equipment (not shown).

[0051] Furthermore, such as Figure 2 As shown, a parallel wire penetration portion 26 is provided inside the front opening 16 of the parallel connector housing 14. The parallel wire penetration portion 26 is connected to the periphery of the front opening 16 and protrudes forward. The parallel wire penetration portion 26 is cylindrical in shape. A pair of parallel wire penetration holes 28 are provided at two locations separated in the width direction at the protruding end of the parallel wire penetration portion 26. The pair of parallel wire penetration holes 28 open in the front-rear direction. The pair of parallel wire penetration holes 28 have a rectangular cross-sectional shape. Figure 1 and Figure 2 As shown, a counter-terminal (not shown) that is crimped to the end of the terminal wire 30 passes through a pair of counter-terminal wire through holes 28.

[0052] Furthermore, such as Figure 2As shown, a pair of protrusions 32 are provided at the center of the upper surface of the connector housing 14 on the opposite side in the width direction (Y-axis direction in the figure). The pair of protrusions 32 extend approximately the entire length in the length direction and are separated in the width direction. Here, the width direction (Y-axis direction in the figure) refers to the left-right direction when the connector unit 10 is viewed from the front or rear in the length direction with the Z-axis direction in the figure aligned with the vertical direction. In addition, a locking protrusion 34 is formed on the rear side of the pair of protrusions 32 in the length direction. The locking protrusion 34 extends in the width direction from the side separated from the opposing protrusion 32 with a generally trapezoidal cross-sectional shape. Furthermore, a locking protrusion 36 is formed between the rear sides of the pair of protrusions 32 in the length direction. The locking protrusion 36 extends in the width direction with a generally triangular cross-sectional shape. The front side surfaces of the locking protrusions 34 and 36 in the length direction are vertical surfaces extending vertically upward. The rearward side of the locking protrusion 34 and the locking protrusion 36 in the longitudinal direction is a conical surface extending obliquely downward. Additionally, as... Figure 5 As shown, a protrusion 38 is provided on one side (inner side) of the lower surface of the outer peripheral surface of the connector housing 14 in the width direction. The protrusion 38 extends along its entire length and protrudes obliquely downward. Furthermore, a pair of protrusions 32 and 38 are formed with different positions and different length dimensions in the vertical direction, depending on the type of connector 12.

[0053] <Connector Unit 10>

[0054] like Figure 3 As shown, the connector unit 10 includes a connector 11, which has: a terminal 42, a female terminal that connects to the end of a wire 40; a housing 44 for retaining the terminal 42; and a connector position guaranteeing member 46 for ensuring proper engagement with the connector 12 on the other side. The connector unit 10 includes a cylindrical connector cover 48 that covers the housing 44 of the connector 11.

[0055] <Shell 44>

[0056] The casing 44 is made of synthetic resin. For example... Figure 3 As shown, the housing 44 has a rectangular shape extending in the length direction and opening in the front-rear direction. Inside the housing 44, terminal holding portions 52 are formed at two locations separated in the width direction. The terminal holding portion 52 has a through hole 50 for a terminal on the opposite side, into which a terminal (not shown) connected to the end of a wire 30 with a terminal attached is inserted. Furthermore, the terminal holding portion 52 internally houses and holds a terminal 42 connected to the end of the wire 40. A terminal through hole 54 for inserting the terminal 42 is formed on the rear side of the housing 44.

[0057] like Figure 3 andFigure 4 As shown in FIG. 6, the front portion 44a of the housing 44 in the longitudinal direction is larger in diameter than the rear portion 44b. The connector position assurance member accommodating portion 58 is formed in the front portion 44a in the longitudinal direction. The central portion of the connector position assurance member accommodating portion 58, which forms the upper portion of the peripheral wall 56 of the housing 44, is protrusively formed toward the upper side over the entire length in the longitudinal direction. Further, the rear side in the longitudinal direction of the connector position assurance member accommodating portion 58 extends toward the rear side. The rear side in the longitudinal direction of the connector position assurance member accommodating portion 58 is open in the rear and upper sides. The stop portion 60 is formed in the upper portion of the peripheral wall 56 of the rear portion 44b of the housing 44 on the rear side in the longitudinal direction of the connector position assurance member accommodating portion 58. The stop portion 60 protrudes toward the upper side and then extends toward both sides in the longitudinal direction. As shown in FIG. 7, the front side of the stop portion 60 has a frame shape extending toward the front side. A stop hole 62 is provided in the central portion of the front side of the stop portion 60 and is provided so as to penetrate in the vertical direction. The rear side of the stop portion 60 has a rectangular flat plate shape extending toward the rear side in a cantilever beam shape. The rear side of the stop portion 60 can be easily released from the stop of the stop hole 62 and the stop protrusion 36 by pressing as described later. Figure 7 and Figure 8 As shown in FIG. 6, the front side of the stop portion 60 has a frame shape extending toward the front side. A stop hole 62 is provided in the central portion of the front side of the stop portion 60 and is provided so as to penetrate in the vertical direction.

The rear side of the stop portion 60 can be easily released from the stop of the stop hole 62 and the stop protrusion 36 by pressing as described later.

[0059] <Connector Position Assurance Member 46>

[0060] The connector position assurance member (CPA member) 46 is made of synthetic resin. As shown in FIG. 6, the connector position assurance member 46 has a rectangular flat plate shape.Figure 3 As shown, the connector position guaranteeing component 46 has a U-shaped frame shape and is open in the forward and vertical directions. The central portion of the upper surface of the connector position guaranteeing component 46 is connected by a rod-shaped connecting portion 74. The front end of the connector position guaranteeing component 46 bends downward in an L-shape, thereby forming a pair of locking portions 76, 76. Furthermore, an operating portion 78 is formed at the rear end of the connector position guaranteeing component 46.

[0061] <Wire 40, rear stop 80 and sealing member 82>

[0062] Furthermore, the housing 44 includes: a wire 40 connected to a terminal 42 and extending from the rear end of the housing 44; and a rear stop 80 and a sealing member 82, mounted on the rear end of the housing 44 to retain the wire 40.

[0063] <Connector Cover 48>

[0064] The connector cover 48 is formed using an elastic material, such as elastic synthetic rubber, thermoplastic elastomers, or other elastomeric materials. Figure 3 and Figure 4 As shown, the connector cover 48 has a rectangular cylindrical shape that extends in the longitudinal direction and is open in the front-rear direction. The front side of the connector cover 48 has a larger diameter than the rear side in the longitudinal direction. The front side of the connector cover 48 is a housing retaining portion 84 that houses and retains the housing 44 of the connector unit 10. The rear side of the connector cover 48 is a wire passing cylindrical portion 86. The wire passing cylindrical portion 86 houses and retains the wire 40 that is connected to the terminal 42 and extends rearward.

[0065] like Figure 3 As shown, a recessed receiving portion 88 is provided on the housing retaining portion 84 on the front side of the connector cover 48. The recessed receiving portion 88 is provided with openings forward and inward at positions corresponding to the receiving recess 72 provided on the housing 44. Additionally, a receiving portion 89 is provided on the upper surface of the front side of the housing retaining portion 84, which internally houses the connector position guarantee component receiving portion 58 of the housing 44. The receiving portion 89 protrudes upward in a rectangular block shape and opens forward and inward. Furthermore, a protrusion 90 protrudes upward in a rectangular block shape on the rear side of the housing retaining portion 84. An opening window 92 is provided through the center of the protrusion 90, opening upward and into the housing retaining portion 84. The opening window 92 has a generally rectangular cross-sectional shape. Figure 1 and Figure 2 As shown, the opening window 92 is formed to expose the connector position guaranteeing member 46 to the outside of the connector cover 48. Therefore, even with the connector cover 48 installed in the housing 44 of the connector 11, the connector position guaranteeing member 46 provided in the housing 44 can be visually confirmed through the opening window 92.Figure 11 As shown, an annular protrusion 94 protruding inward and extending circumferentially in a generally triangular cross-sectional shape is provided on the inner peripheral surface of the opening window 92. Multiple protrusions 94 are provided in a vertical direction (Z-axis direction in the attached figure) (three in this embodiment). Here, the inner peripheral surface of the opening window 92 refers to the surface that extends along the opening direction of the opening window 92 (Z-axis direction in the attached figure) and defines the opening of the opening window 92. Furthermore, the vertical direction (Z-axis direction in the attached figure) is a direction that intersects perpendicularly with the X-axis direction in the attached figure, extending in the direction opposite to the opening direction of the opening window 92 of the connector unit 10.

[0066] Furthermore, a cover 98 is connected to the front side of the protrusion 90 via a connecting portion 96 in the width direction. On the bottom surface of the cover 98 (in... Figure 4 A rectangular flat detection rib 100 is provided on the rear side of the surface (located on the upper side in the vertical direction and extending in the X and Y directions) along its entire width. The top surface of the cover 98 (in...) Figure 4 A cylindrical retaining protrusion 102 is provided at the center of the surface (located on the lower side in the vertical direction and extending in the X and Y axes). This facilitates the installation and removal of the cover 98 and improves the operability of installing and removing the cover 98 to the opening window 92. Furthermore, an annular recess 104, opening outwards and extending circumferentially in a generally triangular cross-sectional shape, is provided on the outer peripheral surface of the cover 98. Multiple recesses 104 are provided in the vertical direction (Z direction) (three in this embodiment). The connecting portion 96 of the cover 98 is formed as a thin rectangular plate that can be bent in the thickness direction. This allows the cover 98 to be easily inserted into the opening window 92 from the side where the detection rib 100 is provided. In other words, the cover 98 can be opened and closed freely to cover the opening window 92. Figure 11 As shown, with the opening window 92 covered by the cover 98, the protrusion 94 on the inner peripheral surface of the opening window 92 protrudes towards the outer peripheral surface of the cover 98. Furthermore, the protrusion 94 is received in close contact with the recess 104 on the outer peripheral surface of the cover 98. This improves the sealing between the contact surfaces of the cover 98 and the opening window 92, enhancing the waterproof function of the connector cover 48. Moreover, it prevents the cover 98 from unexpectedly detaching from the opening window 92.

[0067] like Figure 4 As shown, a pressing part 106 is provided on the rear side of the protrusion 90 with an opening window 92 on the connector cover 48. The pressing part 106 has an upwardly arc-shaped protrusion. The pressing part 106 is configured to be easily deformed by pressing in the longitudinal direction. For example... Figure 2As shown, the pressing part 106 is positioned opposite the operating part 78 formed at the rear end of the connector position guaranteeing member 46. The operating part 78 can be pressed by pressing the pressing part 106 from the outside of the connector cover 48 toward the front in the longitudinal direction. Therefore, even when the operating part 78 cannot be visually identified when the connector cover 48 is in its closed state, the operating part 78 can be pressed from the outside of the connector cover 48. Thus, the assembly workability of the connector unit 10 can be improved.

[0068] like Figure 4 and Figure 6 As shown, support portions 108 are provided at the rear ends of the two sides on both sides of the housing retaining portion 84 in the width direction of the connector cover 48. That is, the support portions 108 are provided from each side of the connector cover 48 in a direction (width direction) intersecting the mating direction (forward in the length direction in this embodiment) where the connector unit 10 is mated to the counterpart connector 12. As a result, when the connector unit 10 is mated to the counterpart connector 12, the pressing force in the mating direction can be stably transmitted to the connector unit 10. Therefore, the assembly workability of the connector unit 10 can be improved. Moreover, the support portions 108 are formed in a stepped manner with increasing protrusion height from the outer surface of the connector cover 48 toward the mating side toward the counterpart connector 12 (i.e., toward the forward in the length direction). Therefore, the support portions 108 can be easily shaped to fit the fingertips of the operator pressing the support portions 108, and the operator can press the support portions 108 stably. Furthermore, the protruding height of the support portion 108 gradually increases toward the mating side of the connector 12 on the opposite side.

[0069] like Figures 7 to 10 As shown, a positioning part 110 and an annular sealing part 112 are provided around the periphery of the front opening in the first end 109 of the housing retaining part 84 of the connector cover 48. More specifically, a flange-shaped positioning part 110 protruding inward is provided around the entire periphery of the front opening of the connector cover 48. Figure 9As shown, by making the positioning part 110 abut against the periphery of the front opening in the front part 44a of the housing 44 throughout its entire circumference, positioning between the housing 44 and the connector cover 48 can be easily achieved. Therefore, the assembly workability of the connector unit 10 can be improved. In addition, the contact between the annular sealing part 112 and the rear surface 113 of the opposite connector 12 can be advantageously and easily achieved. Furthermore, the annular sealing part 112 is provided throughout the entire circumference of the outer periphery of the positioning part 110. The annular sealing part 112 has a shape that expands towards the opposite connector 12 side (front side in the length direction) and protrudes in a head-narrow shape. The annular sealing part 112 of the connector unit 10 contacts the rear surface 113 of the opposite connector 12 when the connector unit 10 is engaged with the opposite connector 12. Thus, the top part of the annular sealing part 112 can contact the rear surface 113 of the opposite connector 12 while expanding in a direction away from the central axis of the annular sealing part 112. Therefore, it can advantageously increase the contact area of ​​the rear surface 113 of the opposite connector 12, and improve the sealing performance of the annular seal 112.

[0070] like Figure 4 and Figure 9 As shown, a pair of wire through holes 114 are provided in the wire through tube portion 86 of the connector cover 48, opening in the front-to-back direction. The pair of wire through holes 114 extend in the length direction and are separated in the width direction with a circular cross-sectional shape. That is, the wires 40, which are respectively connected to the two terminals 42, pass through the wire through tube portion 86 of the connector cover 48. A first partition wall 115a and a second partition wall 115b are provided between the pair of wire through holes 114 in the wire through tube portion 86, serving as partitions that are in close contact with the outer surface of each wire 40. The first partition wall 115a and the second partition wall 115b are provided on the inner surface, located between the two wires 40, and delineate the through area of ​​each wire 40. As a result, interference between the two wires 40 can be suppressed, and each wire 40 can be stably held in the wire through tube portion 86. Furthermore, the first partition wall 115a and the second partition wall 115b located between the wires 40 can seal the gaps that arise between the wires 40 when two wires 40 pass through the wire penetration section 86, which would be problematic. Therefore, the waterproofness between the wires 40, which would be problematic when multiple wires 40 pass through the wire penetration section 86, can also be guaranteed. Further, the inner surface of the wire penetration section 86 includes a first surface 116a and a second surface 116b that sandwich two adjacent wires 40 and are opposed vertically. A first partition wall 115a is provided on the first surface 116a, protruding towards the second surface 116b, located between the two wires 40, and in close contact with the outer surface of each wire 40. A second partition wall 115b is provided on the second surface 116b, protruding towards the first surface 116a, located between the two wires 40, and in close contact with the outer surface of each wire 40.

[0071] like Figure 9 As shown, after the wire 40 is passed through, the rear side of the wire-passing cylinder 86 is secured using fastening members such as cable ties. This causes the protruding ends of the first partition wall 115a and the second partition wall 115b to be grounded, defining a pair of wire-passing holes 114 for each wire 40. That is, the protruding ends of the first partition wall 115a and the second partition wall 115b are not connected to the inner surface of the wire-passing cylinder 86 and can be separated from the inner surface. Therefore, when performing the operation of passing two wires 40 through the wire-passing cylinder 86, it can be treated as a single wire-passing cylinder 86. In other words, by separating the protruding ends of the first partition wall 115a and the second partition wall 115b from each other, the pair of wire-passing holes 114 can be interconnected. This allows for easy passing of each wire 40 into each wire-passing hole 114. Furthermore, as described above, after the wire 40 passes through, the rear side of the wire-penetrating section 86 is secured using the fastening member 118. This improves the waterproof and dustproof properties of the wire-penetrating section 86. Specifically, the fastening member 118 is fixed to the outer circumferential surface of the wire-penetrating section 86, and the fastening member 118 ensures that the inner surface of the wire-penetrating section 86 contacts the outer surface of the wire 40. Additionally, the wire-penetrating section 86 through which the wire 40 passes has a front end located on the connector cover 48. Figure 9 The middle part is the left end, that is, the opposite side of the length direction of the first end 109 (the middle part is the left end). Figure 9 At the second end 119 (right side), the inner surface of the wire-penetrating cylindrical portion 86 is in close contact with the outer surface of the wire 40. Here, the inner surface of the wire-penetrating cylindrical portion 86 includes the forming surfaces of the first partition wall 115a and the second partition wall 115b, which serve as partitions. Thus, the annular sealing portion 112 ensures the water resistance of the first end 109 side of the connector cover 48. The water resistance of the second end 119 side of the connector cover 48 is ensured by ensuring close contact between the inner surface of the wire-penetrating cylindrical portion 86 and the outer surface of the wire 40. This further enhances the water resistance of the connector cover 48.

[0072] <Assembly method of this embodiment>

[0073] The assembly method of this embodiment will be briefly described below. First, the connector cover 48, the rear stop 80, and the sealing member 82 are pre-attached to the rear end of the wire 40 in the order described. Next, the terminal 42 is prepared so that it is electrically connected to the end of the wire 40. The terminal 42, which is connected to the two wires 40 thus configured, is inserted into the terminal holding portion 52 from the terminal through hole 54 side and pressed inward. As a result, the stop (not shown) provided in the terminal holding portion 52 is locked at the rear end of the terminal 42, and the terminal 42 is stably housed and held in the terminal holding portion 52. Then, the rear stop 80 and the sealing member 82 are moved toward the housing 44 side, and the rear stop 80 is locked onto the locking protrusion 70 of the housing 44. As a result, it is fixed to the rear portion 44b of the housing 44. Next, after inserting the connector position guaranteeing component 46 into the connector position guaranteeing component receiving portion 58 of the housing 44, the connector cover 48 is moved towards the housing 44 to cover it. At this time, the connector position guaranteeing component receiving portion 58 is received in a tight-fitting state in the receiving portion 89 for receiving the connector position guaranteeing component receiving portion 58 provided on the inner peripheral surface of the connector cover 48. The receiving portion 89 is provided on the outer peripheral surface of the housing 44 that contacts the inner peripheral surface of the connector cover 48. The connector position guaranteeing component receiving portion 58 protrudes from the upper part of the outer peripheral surface of the housing 44 toward the inner peripheral surface of the connector cover 48. As a result, misassembly of the connector cover 48 relative to the housing 44, such as vertical reversal, can be suppressed.

[0074] In addition, such as Figure 9 As shown, the positioning part 110 provided at the front end of the housing retaining part 84 of the connector cover 48 is engaged with the front end of the front part 44a of the housing 44. The rear end of the housing retaining part 84 of the connector cover 48 is engaged with the rear surface of the rear stop 80. Thus, the connector cover 48 is positioned and fixed to the housing 44. Figure 9 As shown, the inner surface of the connector cover 48 is tapered at the rear end of the front portion 44a of the housing 44 and at the front side of the rear portion 44b of the housing 44. Therefore, the inner surface of the connector cover 48 and the outer surface of the housing 44 are in tight contact. Thus, as... Figure 7 As shown, the pressing part 106 abuts against the operating part 78 of the connector position guaranteeing member 46. Thus, the connector position guaranteeing member 46 is positioned in a temporary locking position, which is its initial position. Figure 7 As shown, in this state, a pair of receiving recesses 120 are provided with openings to the front and upward between the connector position guaranteeing member 46 and the front side of the locking part 60. The pair of receiving recesses 120 are received by a pair of protrusions 32, 32 provided on the upper surface of the opposite connector housing 14. The result is as follows: Figure 2 As shown, the wire harness 122 of Embodiment 1 of this disclosure, which includes a connector unit 10 and a wire 40 connected to a connector 11 constituting the connector unit 10, is completed.

[0075] Finally, the connector unit 10 is assembled to the counterpart connector 12. More specifically, the pair of protrusions 32, 32 and the protrusion 38 provided on the outer peripheral surface of the counterpart connector housing 14 are received in the pair of receiving recesses 120 and the receiving recess 72 provided in the front portion 44a of the housing 44 of the connector unit 10. Thereby, erroneous assembly of the connector unit 10 in the upside-down direction or the like with respect to the counterpart connector housing 14 can be suppressed. As shown in FIG. 8, in this state, the pair of protrusions 32 is inserted in the pair of receiving recesses 120, and the stopper 76 provided on the front end portion of the connector position assurance member 46 is placed on the tapered surface of the stopper protrusion 34. In addition, the stopper protrusion 36 provided on the counterpart connector housing 14 is engaged with the stopper hole 62 of the stopper 60, and the connector unit 10 is fixed to the counterpart connector 12. This fixation can be easily released by pressing the rear side of the stopper 60. Next, by pressing the pressing portion 106 of the connector cover 48 toward the front side, the stopper 76 is stopped by the stopper protrusion 34, and the fixation becomes firm. Figure 7

[0076] In addition, the operation portion 78 of the connector position assurance member 46 is inserted into the lower side of the rear side of the stopper 60 to prevent release of the fixation (refer to FIG. 8). As shown in FIG. 9, in this state, the detection rib receiving recess 124 is formed between the operation portion 78 of the connector position assurance member 46 and the pressing portion 106. Thereby, the detection rib 100 is received in the detection rib receiving recess 124, and the opening window 92 can be covered with the cover portion 98. That is, the cover portion 98 has the detection rib 100 protruding toward the housing 44 side. Therefore, when the connector position assurance member 46 is located in the formal stop position that assures regular engagement, the detection rib 100 does not interfere with the connector position assurance member 46 disposed in the formal stop position, and the engagement of the cover portion 98 with the opening window 92 is permitted. When the connector position assurance member 46 is not located in the formal stop position that assures regular engagement, the detection rib 100 interferes with the connector position assurance member 46 to prevent the engagement of the cover portion 98 with the opening window 92. That is, the detection rib 100 is provided at a position that satisfies a predetermined condition. More specifically, the predetermined condition is that, when the connector position assurance member 46 is located in the first position different from the second position as the formal stop position, the detection rib 100 interferes with the connector position assurance member 46. When the connector position assurance member 46 is located in the second position, the detection rib 100 does not interfere with the connector position assurance member 46. The connector position assurance member 46 can be moved from the predetermined first position to the second position. Figure 7 8 Figure 1 2 As shown in FIG. 8, in this state, the detection rib receiving recess 124 is formed between the operation portion 78 of the connector position assurance member 46 and the pressing portion 106. Thereby, the detection rib 100 is received in the detection rib receiving recess 124, and the opening window 92 can be covered with the cover portion 98. That is, the cover portion 98 has the detection rib 100 protruding toward the housing 44 side. Therefore, when the connector position assurance member 46 is located in the formal stop position that assures regular engagement, the detection rib 100 does not interfere with the connector position assurance member 46 disposed in the formal stop position, and the engagement of the cover portion 98 with the opening window 92 is permitted. When the connector position assurance member 46 is not located in the formal stop position that assures regular engagement, the detection rib 100 interferes with the connector position assurance member 46 to prevent the engagement of the cover portion 98 with the opening window 92. That is, the detection rib 100 is provided at a position that satisfies a predetermined condition. More specifically, the predetermined condition is that, when the connector position assurance member 46 is located in the first position different from the second position as the formal stop position, the detection rib 100 interferes with the connector position assurance member 46. When the connector position assurance member 46 is located in the second position, the detection rib 100 does not interfere with the connector position assurance member 46. The connector position assurance member 46 can be moved from the predetermined first position to the second position. Figure 1 Figure 8

[0077] ​​​​​​Thus, it is possible to suppress the occurrence of an error such as the omission of the confirmation of the connector position assurance member 46 or the erroneous closing of the cover portion 98. Also, in the state in which the opening window 92 is covered with the cover portion 98, it is possible to more easily confirm that the connector position assurance member 46 is positioned at the formal locking position that assures regular fitting, and it is possible to improve the assembly workability and assembly reliability of the connector unit 10. As a result of the above, the assembly of the connector unit 10 with respect to the counterpart connector 12 is completed. In the fitted state with the counterpart connector 12, the annular seal portion 112 of the connector cover 48 comes into contact with the rear surface 113 of the counterpart connector housing 14. That is, the annular seal portion 112 is provided at a position that can come into contact with the rear surface 113 of the counterpart connector 12 in the fitted state with the counterpart connector 12.

[0078] According to the connector unit 10 of the present disclosure configured as such, the annular seal portion 112 of the connector unit 10 comes into contact with the rear surface 113 of the counterpart connector 12 in the fitted state of the connector unit 10 with the counterpart connector 12. At this time, the gap between the connector cover 48 and the rear surface 113 of the counterpart connector 12 is sealed. Thus, it is possible to improve the waterproofness of the fitted side of the connector unit 10 with the counterpart connector 12. Also, it is advantageously prevented from entering foreign matter such as mud attached to the periphery of the connector cover 48 into the inside of the connector cover 48 at the time of use. Further, at the time of maintenance or the like when the connector unit 10 is inserted into or pulled out from the counterpart connector 12, it is possible to suppress or reduce the occurrence of an adverse situation in which foreign matter enters into the housing 44 to adversely affect the re-fitting of the connector unit 10 and the counterpart connector 12.

[0079] Also, by configuring a wire harness 122 that includes the connector unit 10 and the electric wire 40 connected to the connector 11 of the connector unit 10, it is possible to provide the wire harness 122 that includes the connector unit 10 and that exhibits the same advantageous effects as the above-described connector unit 10.

[0080] Further, in the connector fitting structure of the connector unit 10 and the counterpart connector 12 that fits with the connector unit 10, the annular seal portion 112 of the connector unit 10 comes into contact with the rear surface 113 of the counterpart connector 12 in the fitted state of the connector unit 10 with the counterpart connector 12. Thus, it is possible to provide the connector fitting structure that exhibits the same advantageous effects as the above-described connector unit 10.

[0081] <Other Embodiments>

[0082] The technology described in this specification is not limited to the embodiments described above and illustrated in the drawings, and for example, the following embodiments are also included in the technical scope of the technology described in this specification.

[0083] (1) In the above-described embodiment 1, the protrusion 102 is positioned on the top surface of the cover 98 to a size that allows it to be easily held by the fingers of an operator, but it is not limited to this. For example... Figure 12 As shown in the connector unit 126 of Embodiment 2 of this disclosure, the retaining protrusion 128 can also be configured to a size that is difficult for an operator's fingers to hold. For example, the retaining protrusion 128 with a reduced protrusion height can also have a slit-shaped recess 130 that can hold a tool (not shown). Thus, even if the retaining protrusion 128 is a size that an operator's fingers cannot hold, the retaining protrusion 128 can be held by inserting a tool into the recess 130. As a result, the protrusion height of the retaining protrusion 128 can be suppressed, thus reducing the risk of interference between the retaining protrusion 128 and other components. In addition, the cover 98 can be prevented from accidentally detaching from the opening window 92, further improving the reliability of the connector cover 48's waterproof, shielding, and other protective functions.

[0084] (2) In the above embodiment 1, the partition wall that is in close contact with the outer surface of each wire 40 is formed by a first partition wall 115a protruding from the first surface 116a and a second partition wall 115b protruding from the second surface 116b, but is not limited thereto. The partition wall can be formed by protruding from either the first surface 116a or the second surface 116b, or the partition wall can be formed arbitrarily in terms of protrusion height, number, etc.

[0085] (3) In the above embodiment 1, a protrusion 94 is provided on the inner peripheral surface of the opening window 92 and a recess 104 is provided on the outer peripheral surface of the cover 98. However, a recess may be provided on the inner peripheral surface of the opening window 92 and a protrusion may be provided on the outer peripheral surface of the cover 98.

[0086] (4) In the above embodiment 1, a recessed receiving portion 88 is provided on the inner peripheral surface of the connector cover 48 and a receiving recess 72 is provided on the outer peripheral surface of the housing 44. However, a receiving recess 72 may also be provided on the inner peripheral surface of the connector cover 48 and a recessed receiving portion 88 may be provided on the outer peripheral surface of the housing 44.
