[0013] (5) It is preferable that the flexible connecting portion has a biting portion formed therein into which the electric wire is to be bitten. This configuration improves the reliability of the connection between the flexible connecting portion and the electric wire.

[0014] (6) It is preferable that the flexible connecting portion has a clamping portion for clamping the electric wire in a bent state. This configuration improves the reliability of the connection between the flexible connecting portion and the electric wire.

[0015] [Details of the embodiments of the present disclosure] [Example 1] A waterproof connector according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 8. The present invention is not limited to these examples, but is defined by the claims, and includes all modifications within the meaning and scope of the claims. In this first embodiment, the front-to-back direction is defined as the positive direction of the X axis in FIGS. 1 to 8. The left-to-right direction is defined as the positive direction of the Y axis in FIGS. 1 to 4. The up-down direction is defined as the positive direction of the Z axis in FIGS. 1 to 8.

[0016] As shown in Figures 2 and 8, the waterproof connector of this embodiment is configured with one housing 10, one rubber plug 20, one rear holder 22, a plurality of terminal fittings 30, and a plurality of electric wires 60 individually connected to the plurality of terminal fittings 30. The rubber plug 20 is attached to the rear end of the housing 10, and the rear holder 22 is assembled behind the rubber plug 20. The plurality of terminal fittings 30 are housed in a plurality of terminal accommodating spaces 11 formed within the housing 10. The electric wires 60 are well-known cables in which a single-core wire 61 is surrounded by an insulating coating 62. The electric wires 60 connected to the terminal fittings 30 pass through the rubber plug 20 and the rear holder 22 and are led out to the rear of the housing 10. The rubber plug 20 prevents water from entering from the rear of the housing 10.

[0017] The housing 10 is formed by assembling a housing main body 12 made of synthetic resin and a front member 24 made of synthetic resin. A plurality of rear terminal accommodating chambers 13 are formed inside the housing main body 12. As shown in FIG. 5, the rear terminal accommodating chambers 13 are open to the front surface of the housing main body 12. As shown in FIGS. 5 and 8, a movement restricting portion 14 is formed at the rear end of the rear terminal accommodating chamber 13. A temporary locking protrusion 15 is formed in the rear terminal accommodating chamber 13 at a position forward of the movement restricting portion 14. A plurality of wire insertion chambers 16 are formed inside the housing main body 12. The plurality of wire insertion chambers 16 are located rearward of the plurality of rear terminal accommodating chambers 13 and open to the rear surface of the housing main body 12. The rear ends of the plurality of rear terminal accommodating chambers 13 and the front ends of the plurality of wire insertion chambers 16 are in communication in the front-rear direction.

[0018] A peripheral wall portion 17 having a rectangular cylindrical shape that protrudes rearward from the outer periphery of the housing body 12 is formed at the rear end of the housing body 12. A one-piece rubber stopper 20 is housed within a seal space 18 surrounded by the peripheral wall portion 17. The one-piece rubber stopper 20 has a plurality of seal holes 21 formed therein that penetrate the one-piece rubber stopper 20 in the front-to-rear direction. The front ends of the plurality of seal holes 21 communicate with the rear ends of the plurality of electric wire insertion chambers 16. A rear holder 22 is attached within the seal space 18 to prevent the one-piece rubber stopper 20 from coming off rearward from the housing body 12. The rear holder 22 has a plurality of electric wire through holes 23 formed therein that individually communicate with the rear ends of the plurality of seal holes 21.

[0019] The front member 24 is attached to the housing main body 12 so as to cover the front surface of the housing main body 12. A plurality of front terminal accommodating chambers 25 are formed in the front member 24. The front terminal accommodating chambers 25 are open to the rear surface of the front member 24. A front stop portion 26 is formed at the front end of the front terminal accommodating chambers 25. A plurality of tab insertion holes 27 are formed in the front surface of the front member 24, which individually communicate with the front ends of the plurality of front terminal accommodating chambers 25.

[0020] The housing 10 is constructed by attaching the one-piece rubber plug 20, rear holder 22, and front member 24 to the housing main body 12. The front terminal accommodating chamber 25, the rear terminal accommodating chamber 13, the wire insertion chamber 16, the seal hole 21, and the wire through hole 23 are arranged in a straight line in the front-to-rear direction. The front terminal accommodating chamber 25 and the rear terminal accommodating chamber 13 form a terminal accommodating space 11 for accommodating the terminal fitting 30.

[0021] As shown in FIG. 3, the terminal fitting 30 has an elongated shape extending in the front-rear direction as a whole. As shown in FIG. 4, the terminal fitting 30 is formed by assembling a first component 31 and a second component 32. The first component 31 is formed by bending a metal plate material punched into a predetermined shape, and has an elongated shape extending in the front-rear direction as a whole. The first component 31 has a rectangular tubular tab connection portion 33 with both front and rear ends open, a connecting portion 34 protruding rearward from the rear end of the tab connection portion 33, a rectangular tubular support portion 35 extending rearward from the rear end of the connecting portion 34, and a pair of upper and lower flexible connection portions 36, 37 extending rearward in a cantilevered manner from the rear end of the support portion 35. A resilient contact piece 38 (see FIGS. 5 and 8) that contacts the tab (not shown) of a mating terminal (not shown) is housed within the tab connection portion 33.

[0022] The connecting portion 34 has a shape in which a pair of side plates 40 rise from both left and right edges of a bottom plate portion 39. An opening on the top surface of the connecting portion 34 functions as a detection hole 41 for confirming the presence of an electric wire 60. Holding protrusions 42 are formed on both left and right outer surfaces of the support portion 35.

[0023] The pair of flexible connection portions 36, 37 are plate-shaped with their thicknesses oriented in the vertical direction, and are capable of plastically or elastically deforming in the vertical direction so as to approach each other. As shown in Figures 6 and 7, a front bulge 43 is formed at the front end of the upper flexible connection portion 36, and projects downward toward the lower flexible connection portion 37. The stepped rear end of the front bulge 43 functions as an upper clamping portion 44. A plurality of groove-like indentations 45 extending in the left-right direction are formed in the area of ​​the underside of the upper flexible connection portion 36 rearward of the front bulge 43.

[0024] A rear bulge 46 is formed in the rear end region of the lower flexible connection portion 37, protruding upward toward the upper flexible connection portion 36. The stepped front end of the rear bulge 46 functions as a lower clamping portion 47 located slightly rearward of the upper clamping portion 44. A plurality of groove-like indentations 45 are formed on the upper surface of the rear bulge 46, extending in the left-right direction.

[0025] The second component 32 is made of a metal material and has a rectangular cylindrical shape elongated in the front-rear direction with both front and rear end surfaces open. An upper pressing portion 50 and a lower pressing portion 51 are formed inside the second component 32. The upper pressing portion 50 has a shape in which the lower surface of the upper wall portion constituting the second component 32 protrudes downward. An upper guide surface 52 is formed at the front end of the upper pressing portion 50, which is inclined so that it gradually becomes higher toward the front. The lower pressing portion 51 has a shape in which the lower wall portion constituting the second component 32 is bent so that it protrudes upward. A lower guide surface 53 is formed at the front end of the lower pressing portion 51, which is inclined so that it gradually becomes lower toward the front.

[0026] A retaining projection 54 is formed on the top surface of the second component 32. An initial position locking hole 55 and a connecting position locking hole 56 are formed in a pair of left and right side wall portions that constitute the second component 32. The initial position locking hole 55 is located at the front end portion of the second component 32. The connecting position locking hole 56 is located behind the initial position locking hole 55.

[0027] Next, the assembly procedure for the waterproof connector of the first embodiment will be described. The one-piece rubber plug 20 and rear holder 22 are assembled into the seal space 18 of the housing body 12. Regarding the terminal fitting 30, the rear end portion of the first component 31 is inserted into the front end portion of the second component 32, and the retaining projection 42 is fitted into the initial position locking hole 55. The retaining projection 42 and the initial position locking hole 55 lock the second component 32 in its initial position relative to the first component 31. When the second component 32 is in its initial position, as shown in FIG. 6 , the rear end portion of the support portion 35 and the entire upper and lower flexible connecting portions 36, 37 are housed within the second component 32. The rear ends of the upper and lower flexible connecting portions 36, 37 are positioned slightly forward of the upper guide surface 52 and the lower guide surface 53. At the front end of the electric wire 60, the insulating coating 62 is removed to expose the single-core wire 61.

[0028] Next, the terminal fitting 30 is inserted into the rear terminal accommodating chamber 13 from the front of the housing main body 12. With the terminal fitting 30 inserted into the rear terminal accommodating chamber 13, the rear end of the second part 32 faces the movement restricting portion 14 from the front and can be locked, and the retaining projection 54 of the second part 32 can be locked with the temporary locking projection 15 of the rear terminal accommodating chamber 13 from the rear. The terminal fitting 30 is held in an assembled state in the housing main body 12 by the locking action of the movement restricting portion 14 and the temporary locking projection 15. In this state, the second part 32 is entirely accommodated in the rear terminal accommodating chamber 13. The rear end portion of the support portion 35 of the first part 31, the entire upper flexible connecting portion 36, and the entire lower flexible connecting portion 37 are accommodated in the rear terminal accommodating chamber 13 and the second part 32. Of the first component 31, the entire tab connection portion 33, the entire linking portion 34, and a front end portion of the support portion 35 protrude forward from the front surface of the housing body 12 and are exposed.

[0029] Around the time of attaching the terminal fitting 30 to the housing body 12, the electric wire 60 is inserted into the housing body 12 from the rear of the rear holder 22. The electric wire 60 is inserted sequentially through the electric wire through-hole 23 of the rear holder 22, the seal hole 21 of the one-piece rubber plug 20, the electric wire insertion chamber 16 of the housing body 12, and the rear terminal accommodating chamber 13. In a plan view of the terminal fitting 30 seen from above, the insertion of the electric wire 60 is completed when the front end 61F of the single-core wire 61 reaches the opening area of ​​the detection hole 41. The portion of the electric wire 60 where the insulating coating 62 covers the single-core wire 61 is in liquid-tight contact with the inner circumferential surface of the seal hole 21. Only the portion of the electric wire 60 where the single-core wire 61 is exposed is accommodated inside the terminal fitting 30. The single core wire 61 is inserted between the upper pressing portion 50 and the lower pressing portion 51 , and is also inserted between the upper flexible connecting portion 36 and the lower flexible connecting portion 37 .

[0030] The connecting portion 34 in which the detection hole 41 is formed is exposed to the outside of the housing body 12. Therefore, it is possible to check from above the terminal fitting 30 visually or with a camera (not shown) whether the front end 61F of the single-core wire 61 is located within the opening area of ​​the detection hole 41.

[0031] Next, with first component 31 fixed by a jig (not shown), second component 32 is moved forward relative to first component 31. When moving second component 32 relative to first component 31, housing body 12, one-piece rubber plug 20, rear holder 22, and electric wires 60 are moved forward together, and movement restricting portion 14 pushes second component 32 from the rear. When second component 32 reaches the connection position, connection position locking hole 56 and holding protrusion 42 fit together, and this fit holds second component 32 in the connection position.

[0032] As the second component 32 moves to the connection position, the upper guide surface 52 of the upper pressing portion 50 deforms the upper flexible connection portion 36 downward, and the lower guide surface 53 of the lower pressing portion 51 deforms the lower flexible connection portion 37 upward. When the second component 32 has moved to the connection position, the upper flexible connection portion 36, which has been pressed downward by the upper pressing portion 50, and the lower flexible connection portion 37, which has been pressed upward by the lower pressing portion 51, sandwich the single-core wire 61 from above and below. This allows the single-core wire 61 to be electrically connected to the first component 31.

[0033] The single core wire 61 bites into the biting portion 45 of the upper flexible connection portion 36 and the biting portion 45 of the lower flexible connection portion 37. This biting prevents the single core wire 61 from moving in the front-to-rear direction relative to the first component 31. In front of the biting portion 45, the single core wire 61 is clamped in a stepped bent state between the upper clamping portion 44 and the lower clamping portion 47. This clamping also prevents the single core wire 61 from moving in the front-to-rear direction relative to the first component 31. This completes the connection between the electric wire 60 and the terminal fitting 30.

[0034] After connecting the electric wires 60 and the terminal fittings 30, the front member 24 is assembled to the front end of the housing body 12. Assembly of the front member 24 completes assembly of the housing 10. With the housing 10 assembled, the rear terminal accommodating chambers 13 and the front terminal accommodating chambers 25 are lined up and connected to each other from front to back, thereby forming the terminal accommodating space 11, and the entire terminal fittings 30 are accommodated within the terminal accommodating space 11. The front stop portion 26 at the front end of the front terminal accommodating chamber 25 prevents the terminal fittings 30 from moving forward relative to the housing 10. This completes assembly of the waterproof connector.

[0035] 1 and 2, the waterproof connector of the first embodiment has a housing 10, a plurality of terminal fittings 30, a lump-sum rubber stopper 20, and a plurality of electric wires 60. The plurality of terminal fittings 30 are individually accommodated in a plurality of rear terminal accommodating chambers 13 from the front of the housing 10. The lump-sum rubber stopper 20 has a plurality of seal holes 21 and is attached to the rear end of the housing 10. The plurality of electric wires 60 pass through the seal holes 21 from the rear of the lump-sum rubber stopper 20 and are accommodated in the terminal fittings 30 accommodated in the terminal accommodating spaces 11.

[0036] The terminal fitting 30 is formed by assembling a first part 31 and a second part 32. The first part 31 is made of a conductive material and has a pair of upper and lower flexible connecting portions 36, 37 that can sandwich the single-core wire 61 of the electric wire 60. The second part 32 has an upper pressing portion 50 and a lower pressing portion 51 and is movable relative to the first part 31 in the front-to-rear direction between an initial position and a connecting position. As the second part 32 moves from the initial position to the connecting position, the upper flexible connecting portion 36 and the lower flexible connecting portion 37 are deformed by the upper pressing portion 50 and the lower pressing portion 51, respectively, to sandwich the single-core wire 61 of the electric wire 60 from above and below. With this configuration, it is not necessary to pass the terminal fitting 30 through the seal hole 21 of the one-piece rubber plug 20, and therefore the inner circumferential surface of the seal hole 21 is not damaged by the terminal fitting 30. This prevents a decrease in the reliability of the sealing performance.

[0037] The housing 10 includes a housing main body 12 in which a rear terminal accommodating chamber 13 is formed, and a front member 24 attached to the front end of the housing main body 12 and providing a front stop for the terminal fitting 30 attached to the rear terminal accommodating chamber 13. The first component 31 is movable in the front-to-rear direction relative to the housing main body 12 with the front end of the first component 31 protruding forward from the housing main body 12. The second component 32 moves integrally with the housing main body 12 between an initial position and a connected position. With this configuration, by detecting the relative positional relationship between the housing main body 12 and the first component 31, the relative positional relationship of the second component 32 with respect to the first component 31 can be ascertained, and thus it can be determined whether the electric wire 60 and the terminal fitting 30 are connected.

[0038] The portion of the electric wire 60 where the single core wire 61 is exposed is housed inside the first part 31. A detection hole 41 is formed in the first part 31. Through the detection hole 41, the front end 61F of the single core wire 61 of the electric wire 60 housed in the first part 31 can be visually observed from outside the housing main body 12. With this configuration, it can be detected whether the terminal fitting 30 and the single core wire 61 of the electric wire 60 are connected in a proper positional relationship.

[0039] A movement restricting portion 14 that restricts the rearward relative movement of the terminal fitting 30 is formed in the rear terminal accommodating chamber 13. With this configuration, the terminal fitting 30 can be held in the appropriate position within the terminal accommodating chamber without forming a lance in the housing body 12.

[0040] The upper flexible connecting portion 36 and the lower flexible connecting portion 37 are formed with biting portions 45 into which the single core wire 61 of the electric wire 60 is bitten. This configuration improves the connection reliability between the upper and lower flexible connecting portions 36, 37 and the single core wire 61 of the electric wire 60. The upper flexible connecting portion 36 and the lower flexible connecting portion 37 are formed with upper clamping portions 44 and lower clamping portions 47 that clamp the single core wire 61 in a bent state. This configuration improves the connection reliability between the upper and lower flexible connecting portions 36, 37 and the single core wire 61.
