[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2016-131133 Summary of the Invention

[0006] Problems to be solved by the invention

[0007] The anti-slip surface formed on the rear end of the lock arm protrudes in a stepped manner from the inner wall of the cover. Therefore, the radial dimension of the area of ​​the cover where the anti-slip surface is formed, namely, the rear end of the lock arm, increases in proportion to the amount of the anti-slip surface. Because the rear end of the lock arm serves as the flexure fulcrum of the lock arm, the formation of the anti-slip surface increases the rigidity of the flexure fulcrum of the lock arm, making the lock arm less susceptible to elastic deformation. Consequently, when the mating connector mated with the cover abuts against the lock arm, causing the lock arm to elastically deform, frictional resistance increases.

[0008] The connector of the present disclosure is completed based on the above-mentioned situation, and aims to prevent the movable arm portion from becoming difficult to bend.

[0009] Solutions to Problems

[0010] The connector disclosed herein has:

[0011] A connector housing capable of engaging with a housing on the other side;

[0012] a sealing ring, mounted on the peripheral surface of the connector housing to seal between the connector housing and the peripheral surface of the counterpart housing;

[0013] an elastically deformable movable arm portion formed on the connector housing; and

[0014] a stopper, which limits the movement of the sealing ring,

[0015] The movable arm portion includes a fulcrum portion and a displacement portion, wherein the displacement portion extends from the fulcrum portion and is displaceable in a direction intersecting with the extending direction.

[0016] The stopper portion is in a shape protruding from the displacement portion.

[0024] [Description of Embodiments of the Present Disclosure]

[0025] First, embodiments of the present disclosure will be described below.

[0026] The connector of the present disclosure,

[0027] (1) A device comprising: a connector housing capable of mating with a mating housing; a sealing ring mounted on the circumference of the connector housing to seal the connector housing with the circumference of the mating housing; an elastically deformable movable arm portion formed on the connector housing; and a stopper portion for restricting movement of the sealing ring, wherein the movable arm portion includes a fulcrum portion and a displacement portion, the displacement portion extending from the fulcrum portion and capable of displacement in a direction intersecting the extending direction, and the stopper portion protruding from the displacement portion. In the case where the stopper portion protrudes from the fulcrum portion of the movable arm portion, as in Patent Document 1, the fulcrum portion becomes thick, thereby increasing the rigidity of the fulcrum portion and making it difficult for the movable arm portion to bend. In contrast, the stopper portion of the present disclosure is formed only on the displacement portion of the movable arm portion, so the fulcrum portion can be thin, thereby suppressing the rigidity of the fulcrum portion. Thus, it is possible to prevent the movable arm portion from becoming difficult to bend.

[0028] (2) It is preferable that the stopper portion is formed only in a region of the displacement portion that is separated from the fulcrum portion. According to this configuration, the influence of the increase in rigidity due to the formation of the stopper portion is less likely to affect the fulcrum portion.

[0029] (3) In (2), the stopper is preferably arranged with a gap between the stopper and the fulcrum in the extending direction of the displacement portion. According to this configuration, the influence of the increase in rigidity due to the formation of the stopper is less likely to affect the fulcrum.

[0030] (4) In (3), it is preferred that the opposing surface of the stopper portion, which faces the sealing ring, be inclined so as to approach the sealing ring as it protrudes toward the stopper portion. With this configuration, when the sealing ring is pressed by the opposing surface of the stopper portion, the sealing ring enters the space defined by the displacement portion and the opposing surface. This makes it difficult for the sealing ring to leave the peripheral surface of the connector housing, thereby improving sealing performance.

[0031] (5) In (4), preferably, when the movable arm portion is elastically deformed from a free state in which no elastic deformation occurs, the displacement direction of the displacement portion is such that the opposing surface moves away from the sealing ring. This configuration can prevent the stopper from digging into the sealing ring when the movable arm portion is elastically deformed.

[0032] (6) Preferably, the connector housing is equipped with a positioning member, the positioning member being movable between a first position for positioning the top end of the protrusion of the male terminal part and a second position for positioning the base end of the protrusion, the movable arm portion being capable of holding the positioning member in the first position, and the movable arm portion being elastically deformed by the mating housing during mating with the mating housing to disengage from the positioning member. With this configuration, the mating force required to elastically deform the movable arm portion during mating with the mating housing can be reduced.

[0033] [Details of the embodiments of the present disclosure]

[0034] [Example 1]

[0035] Reference Figures 1 to 5 The present invention is not limited to these examples, but is shown by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims. Figure 3 、 5 As shown, the connector of the present embodiment 1 includes a female connector F and a male connector M. The female connector F is a female connector in which a plurality of female terminal fittings 41 are accommodated in a female housing 40 .

[0036] In the present embodiment 1, regarding the front-back direction of the male connector M, Figure 1 、 3 The left direction in ~5 is defined as the front. Figures 1 to 5 The directions shown are defined as upward and downward. Figure 2The directions shown are defined as left and right as they are.

[0037] The male connector M includes a male housing 10, a male terminal part 18, a general rubber plug 23, and a positioning member 25. The male housing 10 is composed of a housing body 11 made of synthetic resin and a cover-shaped front member 12 assembled to the front end of the housing body 11. A cylindrical sealing portion 13 is formed at the front end of the housing body 11 and is continuous throughout the entire circumference. Figure 2 As shown, when the housing body 11 is viewed from the front, the sealing portion 13 is formed as a whole into a rectangle that is long in the left-right direction, and more specifically, into a rectangle with four corners formed into quarter-circular arc shapes.

[0038] like Figure 1 As shown, a sealing ring 15 is mounted on the inner circumferential surface of the sealing portion 13. The sealing ring 15 is inserted into the sealing portion 13 from the front of the housing body 11. The front-to-back dimension of the sealing ring 15 is greater than the radial dimension (thickness direction) of the sealing ring 15. The sealing ring 15 provides a liquid-tight seal between the inner circumferential surface of the housing body 11 and the outer circumferential surface of the female housing 40.

[0039] A plurality of cavities 16 spaced apart in the left-right direction are formed in the shell body 11. The cavity 16 is arranged further to the rear than the sealing portion 13. A male terminal part 18 is inserted into each cavity 16 from the rear of the shell body 11. The male terminal part 18 is elongated in the front-to-back direction as a whole. The male terminal part 18 has a square cylindrical terminal body 19, a protrusion 20 protruding forward from the terminal body 19, and an open cylindrical crimping part 21 connected to the rear end of the terminal body 19. The front end of the electric wire 22 is fixed to the crimping part 21. The electric wire 22 passes through the general rubber plug 23 assembled at the rear end of the shell body 11 and is led out to the rear of the male side shell 10.

[0040] The housing body 11 contains a positioning member 25. The positioning member 25 can be positioned in a first position (see FIG. Figure 1 、 3 , 4) and the second position behind the first position (refer to Figure 5 ) are moved between the positions of the protrusions 20 and the protrusions 20. The positioning member 25 is formed with a plurality of positioning holes 26 for individually passing through the plurality of protrusions 20. When the positioning member 25 is in the first position, the top end (front end) of the protrusion 20 is positioned by the positioning holes 26. When the positioning member 25 is in the second position, the base end (rear end) of the protrusion 20 is positioned by the positioning holes 26. A pair of protrusions 27 are formed on the upper and lower edge portions of the positioning member 25.

[0041] The housing body 11 is formed with a pair of vertically symmetrical movable arms 30 that extend rearward in a cantilevered manner from the rear end of the sealing portion 13. The pair of movable arms 30 are located in the left-right center of the upper and lower walls that constitute the sealing portion 13. In the front-to-back direction, the movable arms 30 are located in an area rearward of the sealing portion 13 and the sealing ring 15 and forward of the cavity 16.

[0042] The movable arm portion 30 includes a fulcrum portion 31 connected to the rear end of the sealing portion 13, and a displacement portion 32 extending rearward in a cantilevered manner from the fulcrum portion 31. The fulcrum portion 31 is located on the outer peripheral surface of the rear end of the sealing portion 13. The displacement portion 32 is always held in a locked position in the front-to-back direction (a direction parallel to the mating direction of the female connector F with the male connector M) (see FIG. Figure 1 、 5 The movable arm portion 30 can move the displacement portion 32 radially outward from the locking position (in Figure 1 、 3 , 4 in the upper side of the movable arm portion 30 is the upper) release position (refer to Figure 3 、 4 When the displacement portion 32 is displaced to the unlocking position, the displacement portion 32 is directed toward the outer surface side of the movable arm portion 30 (at the center of the fulcrum portion 31). Figure 1 、 3 , the upper movable arm portion 30 in 4 is inclined obliquely (the upper surface side).

[0043] like Figure 4 As shown, a locking protrusion 34 is formed at the extended end (rear end) of the displacement portion 32, projecting from the inner surface of the displacement portion 32 toward the inner circumference (opposite to the direction in which the displacement portion 32 is displaced toward the unlocked position). A bulge 35 is formed on the inner surface of the displacement portion 32, in a portion forward of the locking protrusion 34, projecting toward the inner surface. The thickness of the bulge 35 in the displacement direction (radial direction) of the displacement portion 32 is greater than that of the base end of the displacement portion 32 (i.e., the front end closest to the fulcrum portion 31) and greater than that of the top end of the displacement portion 32 (i.e., the portion where the locking protrusion 34 is formed). An interference portion 36 is formed on the rear end region of the inner surface of the bulge 35, projecting toward the inner surface relative to the front end of the bulge 35.

[0044] The portion of the bulged portion 35 that is located forward of the interference portion 36 functions as a stopper 37. The stopper 37 projects in a stepped manner toward the inner surface (in the direction approaching the female terminal fitting 41) relative to the inner circumference of the seal portion 13. The stopper 37 is located only in the displacement portion 32 of the movable arm portion 30. The front end 37F of the stopper 37 is located rearward of the front end of the displacement portion 32, that is, rearward of the fulcrum portion 31. The stopper 37 and the fulcrum portion 31 are spaced apart in the direction in which the displacement portion 32 extends (i.e., the front-to-back direction).

[0045] The stopper 37 is arranged so as to face the rear end of the seal ring 15 in the front-to-back direction. The front end surface of the stopper 37 (the facing surface 38 facing the rear end of the seal ring 15 in the front-to-back direction) is inclined relative to the front-to-back direction (the direction in which the male housing 10 and the mating housing are fitted). That is, the facing surface 38 protrudes from the inner surface of the displacement portion 32 toward the stopper 37 ( Figure 4 The facing surface 38 and the rear end surface of the seal ring 15 are inclined in such a manner that the facing distance in the front-to-back direction becomes narrower.

[0046] When the rear end surface of the seal ring 15 (not elastically deformed) and the front end of the stopper 37 (not elastically deformed) of the movable arm 30 are in contact, a space S is ensured between the inclined facing surface 38 of the stopper 37 and the rear end surface of the seal ring 15. This space S is the space into which the rear end of the seal ring 15 enters while elastically deforming in a wedge shape when the seal ring 15 moves rearward.

[0047] When the movable arm portion 30 is in a free state without elastic deformation, the rear end 38R of the facing surface 38 of the stopper portion 37 (the portion of the facing surface 38 that is connected to the inner surface of the displacement portion 32 at an acute angle) is located rearward of the fulcrum portion 31 (forward in the extension direction of the movable arm portion 30). Because the facing surface 38 of the stopper portion 37 is inclined with respect to the front-to-back direction, the front end 37F of the stopper portion 37 (the portion of the facing surface 38 that is farthest from the inner surface of the displacement portion 32) is located forward of the rear end 38R of the facing surface 38 of the stopper portion 37 and at the same position as the fulcrum portion 31 in the front-to-back direction.

[0048] When the male connector M and the female connector F are disengaged, the locking protrusion 34 of the movable arm 30 is locked to the protrusion 27 of the positioning member 25, so that the positioning member 25 is maintained in the first position. The protrusion 20 of the male terminal part 18 is positioned by passing through the positioning hole 26. When the female connector F is mated with the male connector M in this state, the female housing 40 is inserted into the front member 12 and is mated while sliding with the inner peripheral surface of the sealing ring 15. At this time, the sealing ring 15 is about to move backward (towards the rear) relative to the male housing 10 due to the pressing force from the front end of the female housing 40 in the mating direction and the friction resistance between the female housing 40 and the outer peripheral surface. Figures 3-5 right in the middle) relative movement.

[0049] However, because the rear end of the seal ring 15 contacts the opposing surface 38 of the stopper 37, the seal ring 15 is prevented from significantly shifting rearward. Furthermore, when the seal ring 15 is pressed rearward, the rear end of the seal ring 15 elastically deforms and wedges into the space S defined between the rear end and the opposing surface 38. This wedge-like movement of the rear end of the seal ring 15 toward the inner circumferential surface is restricted. Consequently, the rear end of the seal ring 15 does not fall off the stopper 37, ensuring that the stopper 37's function of preventing displacement is effectively utilized.

[0050] During the mating process of the female housing 40, a pair of upper and lower release locking portions 42 formed at the front end of the female housing 40 in the mating direction interfere with the interference portion 36 of the movable arm 30. This interference causes the movable arm 30 to elastically deform, causing the displacement portion 32 to shift from the locked position to the released position. When the displacement portion 32 shifts to the released position, the locking protrusion 34 disengages from the protrusion 27, allowing the positioning member 25 to move from the first position to the second position. After the displacement portion 32 has shifted to the released position, the female housing 40 abuts against the front surface of the positioning member 25.

[0051] When the movable arm portion 30 elastically deforms, the displacement portion 32 is displaced so as to tilt with the fulcrum portion 31 serving as a fulcrum. The bulged portion 35 of the displacement portion 32, where the stopper portion 37 is formed, has a greater thickness in the displacement direction of the displacement portion 32. The thickness of the fulcrum portion 31 of the movable arm portion 30 is smaller than the thickness of the bulged portion 35. Therefore, the rigidity of the fulcrum portion 31 is lower than the rigidity of the portion of the movable arm portion 30 where the stopper portion 37 is formed. Consequently, the mating resistance caused by the interference between the interference portion 36 and the female housing 40 is suppressed to a low level.

[0052] When the displacement portion 32 is displaced toward the unlocked position, it assumes an inclined position, so the opposing surface 38 moves forward away from the rear end of the seal ring 15. Therefore, as the displacement portion 32 moves, the stopper 37 does not intrude into the rear end of the seal ring 15. Even when the displacement portion 32 is displaced toward the unlocked position, the opposing surface 38 maintains its positional relationship relative to the rear end of the seal ring 15 in the front-to-back direction. Therefore, even if the seal ring 15 shifts rearward due to frictional resistance with the female housing 40, further forward displacement is limited by contact with the opposing surface 38. Consequently, the seal ring 15 does not move integrally with the female housing 40 and remains in close contact with the inner circumferential surface of the seal portion 13.

[0053] Furthermore, because the unlocking portion 42 is formed in a protruding shape, when the unlocking portion 42 passes the interference portion 36, the displacement portion 32 returns from the unlocking position to the locking position due to the elastic restoring force of the movable arm portion 30. This restoring action causes the facing surface 38 to approach the rear end of the seal ring 15, so that the seal ring 15 does not move integrally with the female housing 40 and remains in close contact with the inner circumferential surface of the seal portion 13.

[0054] After the female housing 40 abuts against the front surface of the positioning member 25, when the female connector F is mated, the positioning member 25 and the female housing 40 are pushed together, and accordingly, the portion of the tab 20 that penetrates the positioning hole 26 moves from the front end to the rear end of the tab 20. When the female connector F and the male connector M are properly mated, the male terminal fitting 18 and the female terminal fitting 41 are connected.

[0055] The connector of this embodiment 1 has a male housing 10 that can be mated with a female housing 40 and a sealing ring 15. The sealing ring 15 is assembled on the inner peripheral surface of the male housing 10 to seal between it and the outer peripheral surface of the female housing 40. A movable arm portion 30 that can be elastically deformed is formed on the male housing 10. The movable arm portion 30 has a fulcrum portion 31 and a displacement portion 32. The displacement portion 32 extends rearward from the fulcrum portion 31 and can be displaced toward the outer surface side that intersects the extension direction. The male housing 10 has a stop portion 37 that limits the rearward movement of the sealing ring 15. The stop portion 37 is in a form that protrudes from the displacement portion 32.

[0056] Unlike this embodiment, where the stopper protrudes from the fulcrum of the movable arm, the fulcrum becomes thicker, increasing its rigidity and making the movable arm less likely to flex. In contrast, the stopper 37 of this embodiment is formed only in the displacement portion 32 of the movable arm 30, allowing the fulcrum 31 to be thinner, thus reducing its rigidity. This prevents the movable arm 30 from becoming less susceptible to flexion.

[0057] The stopper portion 37 is formed only in the region of the displacement portion 32 that is separated from the fulcrum portion 31. Furthermore, the stopper portion 37 is disposed with a gap between the fulcrum portion 31 and the extension direction (front-back direction) of the displacement portion 32. As a result, the increased rigidity of the displacement portion 32 due to the formation of the stopper portion 37 is less likely to affect the fulcrum portion 31.

[0058] The surface 38 of the stopper 37 that faces the seal ring 15 is inclined so as to approach the seal ring 15 as it moves toward the protruding direction of the stopper 37. With this configuration, when the seal ring 15 is pressed by the facing surface 38 of the stopper 37, the seal ring 15 enters the space S defined by the displacement portion 32 and the facing surface 38. This makes it difficult for the seal ring 15 to leave the peripheral surface of the male housing 10, thereby improving sealing performance.

[0059] When the movable arm 30 is elastically deformed from its free state, the displacement direction of the displacement portion 32 is such that the facing surface 38 moves forward away from the seal ring 15. This configuration prevents the stopper 37 from digging into the seal ring 15 when the movable arm 30 is elastically deformed.

[0060] The male housing 10 is equipped with a positioning member 25. The positioning member 25 is movable between a first position, in which the tip of the tab 20 of the male terminal fitting 18 is positioned, and a second position, in which the base of the tab 20 is positioned. The movable arm 30 holds the positioning member 25 in the first position. During the mating process between the female housing 40 and the male housing 10, the female housing 40 elastically deforms the movable arm 30, disengaging it from the positioning member 25. At this time, the rigidity of the fulcrum 31 decreases as described above, thereby reducing the mating force required to elastically deform the movable arm 30 during mating of the female housing 40.

[0061] [Other embodiments]

[0062] The present invention is not limited to the embodiments described above and illustrated in the drawings, but is shown by the claims.
