Example 1
A first embodiment of the present invention will be described below with reference to FIGS. The connector A according to the first embodiment includes a housing 10 made of synthetic resin, a plurality of terminal fittings 16, and a cap 30 made of synthetic resin. In the following description, the left direction in FIGS. 1 to 3 is defined as the front in the rear direction. Further, with regard to the upper and lower directions, the directions appearing in FIGS. 1 to 8 are defined as upper and lower as they are.

  As shown in FIGS. 1 to 3, the housing 10 includes a main body portion 11 having a block shape, and a cylindrical fitting portion 12 configured to cover an upper surface, a lower surface, and left and right side surfaces of the main body portion 11. A plurality of terminal accommodating chambers 13 are formed inside the main body portion 11. Each terminal accommodating chamber 13 is elongated in the front-rear direction, and the plurality of terminal accommodating chambers 13 are arranged in the lateral direction. The rear end portion of the terminal accommodating chamber 13 is opened as a terminal insertion port 14 on the rear end surface of the housing 10. A front end portion of the terminal storage chamber 13 is opened as a tab insertion port 15 in the front end surface of the housing 10. When a mating connector (not shown) is fitted to the housing 10 from the front, a tab of a male terminal fitting (not shown) attached to the mating connector is inserted into the tab insertion port 15 It has become.

  Female terminal fittings 16 are inserted into the terminal receiving chambers 13 from the rear of the housing 10, respectively. An open barrel crimped portion 17 is formed at the rear end portion of the terminal fitting 16, and the front end portion of the electric wire 18 and the cylindrical rubber plug 19 are collectively fixed to the crimped portion 17. In a state where the terminal fitting 16 is inserted into the terminal storage chamber 13, the lip portion of the outer periphery of the rubber plug 19 is liquid-tight (with respect to the rear end region near the terminal insertion port 14 in the inner peripheral surface of the terminal storage chamber 13) It comes in close contact (airtight). Therefore, the space in front of the rubber plug 19 in the terminal accommodating chamber 13 and the external space in the rear of the housing 10 are airtightly partitioned.

  The rear end portion of the cylindrical fitting portion 12 is continuous with the outer peripheral rear end portion of the main body portion 11. A space partitioned by the outer periphery of the main body portion 11 and the inner periphery of the cylindrical fitting portion 12 is open on the front surface of the housing 10, and a fitting space 20 for fitting the cylindrical portion 31 of the cap 30 and a mating connector. It has become. In the insertion space 20, a ring-shaped seal member 21 attached to the outer periphery of the main body 11 is attached. The seal member 21 is accommodated in the cylindrical fitting portion 12 from the front of the housing 10 and is secured by the front member 22 externally fitted to the front end side region of the outer periphery of the main body portion 11.

  A lock arm 23 is formed on the upper surface (outer surface) of the main body 11 and has an elongated shape in the front-rear direction and can be elastically deformed in a seesaw shape in the vertical direction when viewed from the side. A lock hole 24 is formed at the front end of the lock arm 23 so as to penetrate in the vertical direction. The upper surface area | region corresponding to the lock arm 23 among the cylindrical fitting parts 12 becomes a form cut out for the purpose of facilitating unlocking operation.

  The cap 30 is a single component having a cylindrical portion 31 and a box portion 32 (a tape winding portion described in claims 7 to 13). The cylindrical portion 31 has a form penetrating in the front-rear direction, and has a substantially rectangular cylindrical shape having upper and lower wall portions and left and right wall portions. The space surrounded by the cylindrical portion 31 is an accommodation space 33 in which the front and rear surfaces are opened and the body portion 11 of the housing 10 is accommodated. On the outer surface (upper surface) of the upper wall portion constituting the cylindrical portion 31, a lock portion 34 having a protruding shape is formed.

  The box portion 32 has a form in which only the rear surface (surface facing the housing 10) is opened, and is continuous with the front end portion of the cylindrical portion 31. That is, the box part 32 is a form which protruded from the front end part of the cylindrical part 31 ahead. The inside of the box portion 32 is an air reservoir space 35. The air reservoir space 35 is opened only on the rear surface of the box portion 32, and the rear end portion of the air reservoir space 35 and the front end portion of the accommodation space 33 communicate with each other. A reinforcing portion 36 having a plate shape in which the upper surface and the lower surface are connected to each other is formed in the air reservoir space 35. The reinforcing portion 36 is disposed in a direction in which the plate surfaces face the left and right sides, and divides the air reservoir space 35 into two in the left and right (see FIG. 6). The formation area of the reinforcing portion 36 in the front-rear direction is a continuous range over the entire length of the air reservoir space 35.

  As shown in FIGS. 1 to 5, the height of the upper surface wall constituting the box portion 32 is stepped lower than the upper wall portion constituting the cylindrical portion 31. Due to the difference in height between the upper surface wall and the upper wall portion, the front end portion of the cylindrical portion 31 is a stopper 37 which is relatively higher than the upper surface of the box portion 32. Further, on the left and right side walls constituting the box portion 32, three pairs of displacement restricting portions 38 symmetrical to each other are formed. Each displacement regulating portion 38 has a shape that is elongated in the front-rear direction from the outer surface of the side wall surface in a rib shape. Further, the formation region in the front-rear direction of each displacement restricting portion 38 is a range extending over the entire length of the box portion 32.

  The two displacement restricting portions 38 forming a pair are divided into a left side wall and a right side wall, and arranged at the same height. The three pairs of displacement regulators 38 are disposed at different heights. That is, the pair of displacement restricting portions 38 at the highest position are arranged along the upper edge of the side wall. The pair of displacement restricting portions 38 at the lowest position are arranged along the lower end edge of the side wall. The remaining pair of displacement restricting portions 38 are disposed approximately at the center height (specifically, slightly above the center) of the side wall. A separation restricting projection 39 is formed at the front end of the pair of displacement restricting portions 38 located at the intermediate height.

  The box portion 32 is integrally formed with an attachment portion 40 for attaching the cap 30 to the bracket 50 (other member described in claims). The mounting portion 40 has a pair of left and right side wall portions 41 protruding downward from the lower surface (outer surface) of the box portion 32, a support wall portion 42 connecting lower end edges of both side wall portions 41, and a rear surface of the lower surface of the box portion 32. A locking arm 43 is provided that extends in a cantilevered manner with a space between the end edge portion and the front surface of the support wall portion 42. A locking projection 44 is formed on the lower surface of the locking arm 43, and a front stop 45 having a form protruding downward is formed at the front end of the locking arm 43. As shown in FIG. 3, the bracket 50 is in the form of a horizontal plate, and is cantilevered forward from a vehicle body (not shown) or the like. A locking hole 51 is formed in the bracket 50.

  When attaching the cap 30 to the bracket 50, make the mounting portion 40 horizontally approach from the front with respect to the bracket 50, and insert the bracket 50 in the gap between the upper surface of the support wall 42 and the lower surface of the locking arm 43 To. In the insertion process, the locking projection 44 interferes with the bracket 50, so that the locking arm 43 is elastically bent upward. Then, when the cap 30 reaches the correct mounting position with respect to the bracket 50, as shown in FIG. 3, the forward movement of the cap 30 is restricted by the front end of the bracket 50 abutting against the front stop 45. . At the same time, the locking arm 43 is elastically restored, and the locking hole 51 and the locking projection 44 are locked. This locking action restricts the cap 30 from moving forward with respect to the bracket 50. .

  When the cap 30 and the bracket 50 are not assembled, as shown in FIGS. 1, 2 and 8, the cap 30 abuts the lower surface of the box portion 32 (attachment portion 40) against the outer periphery of the wire harness 52 It can also be fixed by the adhesive tape 53 in a state. The adhesive tape 53 is wound around the outer periphery of the box portion 32 and the outer periphery of the wire harness 52. The box part 32 around which the adhesive tape 53 is wound and the cylindrical part 31 on which the lock part 34 is formed are arranged at different positions separated in the front-rear direction. Therefore, there is no possibility that the adhesive tape 53 is wound around the lock part 34, and the lock function by the lock part 34 and the lock arm 23 is not impaired.

  On the outer peripheral surface of the box portion 32, the adhesive tape 53 is in close contact with the displacement restricting portion 38. The tension in the circumferential direction (winding direction) is applied to the adhesive tape 53, but since the displacement regulating portion 38 is elongated in the front-rear direction, the adhesive tape 53 is likely to be displaced in the circumferential direction with respect to the displacement regulating portion 38 Also, circumferential resistance occurs. Thereby, the adhesive tape 53 is prevented from being displaced in the circumferential direction with respect to the box portion 32.

  In addition, a stopper 37 is formed at the front end of the cylindrical portion 31 so as to be stepped higher than the upper surface of the rear end of the box portion 32. Therefore, even if the adhesive tape 53 wound around the box portion 32 is displaced backward with respect to the cap 30, the backward displacement of the adhesive tape 53 is prevented by contacting the stopper 37. Further, a detachment restricting protrusion 39 that protrudes outward in the width direction from the outer surface of the displacement restricting portion 38 is formed at the front end portion of the displacement restricting portion 38. Therefore, even if the adhesive tape 53 wound around the box portion 32 is displaced forward with respect to the cap 30, the forward displacement of the adhesive tape 53 is prevented by coming into contact with the separation restricting protrusion 39.

  In a state where the mating connector is removed from the housing 10, a cap 30 is assembled to the front end portion of the housing 10 in order to prevent foreign matter from adhering to the terminal fitting 16 and the seal member 21. In the process of assembling the cap 30, the cylindrical portion 31 is inserted into the fitting space 20, and the lock arm 23 interferes with the lock portion 34 to elastically bend upward. Then, when the cap 30 is properly assembled to the housing 10, the lock arm 23 elastically returns and the lock hole 24 is locked to the lock portion 34. This locking action locks the cap 30 and the housing 10 in the assembled state.

  When the cap 30 is assembled, the main body portion 11 is accommodated in the cylindrical portion 31, and the tab insertion port 15 on the front surface of the main body portion 11 is closed by the cap 30. Further, at the back end portion of the insertion space 20, the rear end portion of the cylindrical portion 31 is in close contact with the outer periphery of the seal member 21, and the gap between the outer peripheral surface of the main body portion 11 and the inner peripheral surface of the cylindrical portion 31 is The seal member 21 seals the entire periphery in a liquid tight state. Therefore, even if water enters the deep end portion of the insertion space 20, the water does not reach the tab insertion port 15 along the outer peripheral surface of the main body portion 11 or the inner peripheral surface of the cylindrical portion 31.

  Now, in the process of assembling the cap 30 into the housing 10, as shown in FIG. 2, when the rear end of the cylindrical portion 31 reaches the seal member 21, the housing space 33 in the cylindrical portion 31 and the terminal housing chamber 13 The inside of the sealed space 46 containing the air is sealed airtight. As the fitting operation of the cap 30 and the housing 10 progresses, the volume of the accommodation space 33 decreases, so that the volume of the sealing space 46 also decreases. As a result, the pressure in the sealed space 46 increases, but this pressure increase serves as a resistance when assembling the cap 30 and the housing 10.

  However, since the air reservoir space 35 which forms the sealed space 46 in communication with the front end of the housing space 33 is formed in the cap 30, the volume of the sealed space 46 is equal to that of the air reservoir space 35. Is greatly secured. Therefore, even if the cap 30 and the housing 10 are properly fitted and the volume of the accommodation space 33 is greatly reduced, the overall volume of the sealing space 46 is reduced when the air pool space 35 is not formed. Compared to a smaller size. Thereby, since the pressure rise of the sealed space 46 in the process of assembling the cap 30 and the housing 10 is suppressed, the resistance at the time of assembling the cap 30 and the housing 10 is reduced.

  As described above, the connector A of the first embodiment includes the housing 10 and the cap 30 attachable to the housing 10 from the front thereof. The cap 30 is provided with a cylindrical portion 31 fitted in an airtight manner to the outer periphery of the housing 10, and a box portion 32 in a form projecting forward from the cylindrical portion 31. An air reservoir space 35 communicating with the space surrounded by the cylindrical portion 31 is formed inside the box portion 32.

  According to this configuration, in the process of fitting the cap 30 to the housing 10, the sealing space 46 including the housing space 33 and the housing space 33 inside the cap 30 sealed on the front surface of the housing 10 As the pressure decreases, the pressure increases. However, since the cap 30 includes the air reservoir space 35 communicating with the housing space 33 surrounded by the cylindrical portion 31, the pressure rise in the sealing space 46 including the housing space 33 in the cap 30 is suppressed. . Therefore, the workability at the time of attaching the cap 30 of the housing 10 is good.

  Further, the cap 30 is formed with a reinforcing portion 36 in which the inner surfaces of the air reservoir space 35 are connected to each other. According to this configuration, since the volume of the air reservoir space 35 does not increase or decrease, the workability at the time of attaching the cap 30 to the housing 10 is stabilized. Further, since the mounting portion 40 that can be locked to the bracket 50 is formed on the outer peripheral surface of the box portion 32, the cap 30 can be mounted to the bracket 50 by locking the mounting portion 40.

  In addition, the connector A of the present embodiment includes the housing 10 and the cap 30, and the tubular portion 31 is engaged with the lock arm 23 of the housing 10 to fit the tubular portion 31 and the housing 10. A lock portion 34 that holds the state is formed. According to this configuration, the cap 30 and the housing 10 can be held in a fitted state by the locking of the lock portion 34 and the lock arm 23. The box portion 32 protruding forward from the cylindrical portion 31 also has a function as a tape winding portion for winding the adhesive tape 53. That is, the cap 30 includes a box portion 32 having a function as a tape winding portion, in addition to the cylindrical portion 31 fitted to the housing 10. According to this configuration, the cap 30 can be fixed to another member such as the wire harness 52 by winding the adhesive tape 53 around the box portion 32 (tape winding portion).

  Further, a projection-like displacement restricting portion 38 is formed on the outer peripheral surface of the box portion 32. According to this configuration, when the adhesive tape 53 is wound around the outer periphery of the box portion 32 and the cap 30 is fixed to the wire harness 52 or the like, the adhesive tape 53 is also wound around the projection-like displacement regulating portion 38 It is possible to prevent the tape 53 from being displaced in the circumferential direction.

  Further, at the boundary between the outer periphery of the cylindrical portion 31 and the box portion 32, a stopper 37 is formed so as to protrude in a step-like manner with respect to the outer peripheral surface of the box portion 32. According to this configuration, when the adhesive tape 53 is wound around the outer periphery of the box portion 32 and the cap 30 is fixed to the wire harness 52 or the like, the adhesive tape 53 is wound along the stopper 37. It is possible to prevent displacement to the side of the shape portion 31.
