Detailed Description

[ description of embodiments of the present disclosure ]

Embodiments of the present disclosure will be first described.

The connector of the present disclosure is provided with a connector,

(1) The device is provided with: a male terminal part having a tab; a housing portion having a deflectable lance portion; a cover portion protruding forward from the housing portion; a movable plate disposed in the cover portion so as to be movable between an initial position and a fitting position; and a front stopper body disposed in the cover portion so as to be movable between a standby position and a locking position, the male terminal fitting being locked to the lance portion in the housing portion, the protruding piece being disposed so as to protrude into the cover portion, the moving plate having a positioning hole through which the protruding piece passes, the front stopper body having a restricting portion disposed in a bending space of the lance portion in the locking position and being disposed in front of the housing portion in the standby position, the moving plate having a locking receiving portion, the locking portion being locked to the locking receiving portion so as to be movable from the locking position to the standby position in association with movement of the moving plate from the fitting position to the initial position, the locking portion being movable relative to the locking receiving portion.

The locking portion is locked to the locking receiving portion, and the front stopper moves from the locking position to the standby position in conjunction with the movement of the movable plate from the fitting position to the initial position, so that the front stopper does not need to be independently moved to the standby position, and the workability is excellent.

The locking portion is detachable from the locking receiving portion, and therefore, when the movable plate is positioned at the initial position, the locking state of the locking portion and the locking receiving portion is released, and the front stopper can be moved from the standby position to the locking position. Therefore, even when the movable plate is positioned at the initial position, the front stopper reaches the locking position, and the regulating portion is disposed in the flexing space of the lance portion, thereby realizing the double locking state of the male terminal fitting.

(2) Preferably, the locking portion protrudes forward from a front surface of the front stopper body, and has a locking body at a distal end portion, the locking receiving portion has a locking hole formed penetrating in the movable plate in a front-rear direction, and a locking surface exposed at the front surface of the movable plate, and the locking portion is disposed in the locking hole so that the locking body can be locked to the locking surface.

When the movable plate is positioned at the initial position, the jig or the like is applied to the locking body exposed on the front surface side of the movable plate from the front of the cover portion, and the locking body is separated from the locking surface, whereby the locked state of the locking portion and the locking receiving portion can be released. After the locking state of the locking portion and the locking receiving portion is released, the front stopper is pushed into the housing portion side, whereby the front stopper can be brought to the locking position.

The locked state of the locking portion and the locking receiving portion and the unlocked state can be checked from the front view of the cover portion of the connector 10 or by a sensor.

(3) The connector may further include a female housing fitted into the cover portion, the female housing may include a latch receiving portion, the movable plate may include a latch portion, the latch portion may be latched to the latch receiving portion so as to move from the fitted position to the initial position in conjunction with the detachment of the female housing from the cover portion, the latch portion may be disposed in a pair in a width direction on one side of the movable plate in a height direction, and the latch receiving portion may be disposed in a pair in the width direction on the other side of the movable plate in a height direction.

The engaging portion is engaged with the engaging receiving portion, and thus the movable plate moves from the fitting position to the initial position in conjunction with the disengagement of the female housing from the cover portion, so that the movable plate does not need to be independently moved to the initial position, and workability is excellent.

The hanging and locking part is arranged on one side of the moving plate in the height direction, and the locking receiving part is arranged on the other side of the moving plate in the height direction, so that the hanging and locking part and the locking receiving part can be respectively formed with high degree of freedom. Further, since the engaging portions and the engaging receiving portions are arranged in pairs in the width direction in the movable plate, the movable plate and the front stopper can be smoothly moved to the initial position and the standby position while maintaining balance.

The male terminal member 12 having a size corresponding to each of the male small chamber 19, the male middle chamber 21, and the male large chamber 22 is inserted from the rear. For example, the male terminal fitting 12 accommodated in the male-side large cavity 22 is shown in fig. 1 to 3.

As shown in fig. 1 to 3, the male terminal part 12 is made of a conductive metal, and includes a cylindrical male terminal body 26, a protruding piece 27 protruding forward from the male terminal body 26, and a cylindrical portion 28 connected to the rear of the male terminal body 26. A lance hole 29 is formed in the opening of the male terminal body 26. By the protruding portion of the lance 24 being fitted into the lance hole 29, the male terminal fitting 12 is primarily locked, and the rearward falling-off of the male terminal fitting 12 is restricted.

The male terminal parts 12 inserted into the male small cavities 19 and the male middle cavities 21 are locked in two stages by the side stopper 14, and are doubly locked together with the lance portions 24. In contrast, the male terminal fitting 12 inserted into the male-side large cavity 22 is locked in two stages by the front stopper 16 described later.

The protruding piece 27 protrudes into the cover 18, and is electrically connected to the female terminal member 85 in a fitted state of the female housing 81 and the male housing 11. Barrel 28 is electrically and mechanically crimped to the distal end of wire 100.

As shown in fig. 10, ribs 31 extending in the width direction are formed on the front surface of the housing 17 so as to protrude between the male-side small chambers 19 and the coaxial chambers 23. A pair of engaging pieces 32 are formed between each of the male side small chambers 19 and each of the male side middle chambers 21 in a lower portion of the housing portion 17 so as to protrude forward in the width direction.

As shown in fig. 4 and 8, the engaging piece 32 has a front holding portion 33 and a rear holding portion 34. The front holding portion 33 protrudes inward from the center in the height direction of the inner surface of the engaging piece 32 (the surface of the engaging pieces 32 facing each other on the inner side in the width direction). The rear holding portions 34 project in pairs from both sides in the height direction of the inner surface of the engaging piece 32 to the inside rearward of the front holding portions 33.

As shown in fig. 10, a plurality of coaxial cavities 23 are formed on the widthwise central side of the upper portion of the housing portion 17. The coaxial chambers 23 are formed in plural on the widthwise central side of the lower portion of the housing portion 17. The coaxial cavity 23 has a circular cross section and a larger opening diameter than the male large cavity 22. A pair of deflectable coaxial lance portions 35 are formed protruding in the width direction in the upper portion of the coaxial cavity 23. The housing 17 further includes a stopper 36 extending radially inward from the inner circumference of each of the coaxial cavities 23.

< assembling Structure of connector, fitting method and separation method >

First, the front stopper 16 is assembled to the movable plate 15 from the rear. During the assembly of the front stopper 16, the locking portion 67 is inserted into the locking hole 52 of the plate body 41 from the rear. The locking body 69 of the locking portion 67 interferes with the locking rib 53, and the locking portion 67 is deformed by bending. When the front stopper 16 is assembled properly, the state of deflection of the locking portion 67 is released, the locking rib 53 is fitted into the locking recess 68, and the locking body 69 of the locking portion 67 is engaged with the locking surface 54 of the locking rib 53 so as to face the locking surface (see fig. 5 and 6). The front surfaces of the stopper base 57 and the stopper end 58 are disposed opposite to the rear surface of the plate body 41. Thereby, the front stopper 16 is assembled to the movable plate 15 in a state in which the movement in the front-rear direction is restricted.

Next, the movable plate 15, to which the front stopper 16 is assembled, is assembled into the hood 18 of the male housing 11 from the front. During the assembly of the movable plate 15, the engaging piece 32 of the male housing 11 is inserted into the through hole 47. When the movable plate 15 is assembled normally, the front side holding portion 33 is disposed so as to face the front surface of the plate body 41, and the rear side holding portion 34 is disposed so as to face the rear surface of the plate body 41 (see fig. 4). Thereby, the movable plate 15 is held in a state of being restricted from moving in the front-rear direction with respect to the male housing 11 at the initial position. At the same time, the front stopper 16 is disposed at the standby position with respect to the male housing 11 via the movable plate 15.

When the movable plate 15 is in the initial position, the plate body 41 is disposed so as to be spaced forward from the housing 17 (see fig. 1). Similarly, when the front stopper 16 is in the standby position, the stopper base 57 and the stopper end 58 are also disposed so as to be spaced forward from the housing 17. The restricting portion 65 of the stopper end portion 58 is disposed forward from the flexing space of the lance portion 24 of the male large chamber 22. Accordingly, the lance portion 24 of the male side large chamber 22 is in a state of being flexible and deformable.

Next, the male terminal fitting 12 is inserted into the male large cavity 22 of the housing 17 from the rear. The male terminal fitting 12, after the lance 24 is deformed by flexing, causes the protruding portion of the lance 24 to fit into the lance hole 29 and to be primarily locked with the housing 17. The protruding piece 27 of the male terminal member 12 protrudes into the cover 18, and the tip portion is inserted into the large positioning hole 44 of the plate body 41. This can maintain the state in which the protruding pieces 27 of the male terminal part 12 are arranged in the front-rear direction.

Next, a rod-shaped jig 400 (see fig. 14) is inserted into the cover 18 from the front. As shown in fig. 14, by pressing the tip end portion of the jig 400 obliquely against the corner slope of the locking body 69 of the locking portion 67 exposed on the front surface of the plate body 41, the locking body 69 is displaced from the locking surface 54 toward the slope 55 side, and the locked state of the locking portion 67 and the locking receiving portion 51 is released. Further, as shown in fig. 15, by pushing the jig 400 rearward, the movable plate 15 is left at the initial position, and only the front stopper 16 is pushed by the jig 400 and moves toward the case 17. In this way, the front stop body 16 can reach the locking position. In the locking position, the stopper base 57 and the stopper end 58 are disposed so as to be able to contact the front surface of the housing 17 (see fig. 2). In the locking position, the restricting portion 65 of the stopper end portion 58 enters the flexing space of the lance portion 24 of the male large cavity 22, and the flexing operation of the lance portion 24 is restricted, so that the male terminal fitting 12 is locked in the second stage.

Further, when the front stopper 16 reaches the locking position, the coaxial restricting portion 63 enters the flexing space above the coaxial lance 35, and the flexing operation of the coaxial lance 35 is also restricted, so that the coaxial terminal 13 is locked in the second stage. Specifically, the coaxial limiting portion 63 shown in fig. 13 is disposed above the coaxial lance 35 shown in fig. 4, and is in a two-stage locked state of the coaxial terminal 13. The male terminal members 12 disposed in the male small chamber 19 and the male middle chamber 21 are locked in two stages by the side stopper 14 inserted into the stopper mounting hole 25 from below the housing 17.

Next, the female housing 81 is fitted into the hood 18 of the male housing 11 from the front. The release portion 91 of the female housing 81 shown in fig. 9 interferes with the front side holding portion 33 of the male housing 11 shown in fig. 10 to press the front side holding portion 33, and the engaging piece 32 is deformed to flex to the left and right outside in fig. 10, whereby the holding state of the movable plate 15 in the initial position with respect to the male housing 11 is released. The hooking portion 48 of the movable plate 15 is inserted into the engagement hole 89, and the hooking protrusion 49 at the distal end portion is engaged with the rear surface (rear surface viewed from the female housing 81) of the hooking receiving portion 92 (see fig. 8).

When the female housing 81 and the male housing 11 are fitted by rotation of the lever (not shown), the movable plate 15 moves from the initial position toward the fitting position. During the movement of the movable plate 15, the engagement piece 32 is inserted into the engagement hole 89 of the female housing 81 through the through hole 47, and the rib 31 is inserted into the rib receiving portion 88 of the female housing 81 through the rib insertion hole 46 of the movable plate 15 (see fig. 4). Thereby, the inclination of the movable plate 15 during movement is restricted. When the movable plate 15 reaches the fitting position, the female housing 81 and the male housing 11 are normally fitted (see fig. 3). The tab 27 of the male terminal fitting 12 is inserted into the female terminal fitting 85 at a regular depth to be electrically connected thereto. When the movable plate 15 reaches the fitting position, the locking portion 67 is inserted into the locking hole 52, and the locking body 69 at the distal end is locked to the locking surface 54.

When the female housing 81 and the male housing 11 are disengaged from each other by maintenance or the like, a lever (not shown) is rotated in the disengaging direction. When the female housing 81 moves in a direction away from the housing 17, the hooking protrusion 49 of the hooking portion 48 maintains the locked state with the hooking receiving portion 92, and thus the movable plate 15 moves toward the initial position in conjunction with the female housing 81. Then, when the movable plate 15 moves toward the initial position, the locking body 69 of the locking portion 67 maintains the locking shape with the locking receiving portion 51, so that the front stopper 16 moves toward the standby position as well in conjunction with the movable plate 15.

When the movable plate 15 returns to the initial position, the front holding portion 33 again opposes the front surface of the plate body 41, and further movement of the movable plate 15 is restricted. Then, the locked state of the hooking portion 48 and the hooking receiving portion 92 is released, and the female housing 81 leaves the movable plate 15 at the initial position and is separated from the cover 18. Here, since the locked state of the locking portion 67 and the locking receiving portion 51 can be maintained, when the movable plate 15 is returned to the initial position, the front stopper 16 can also be returned to the standby position. When the front stopper 16 is located at the standby position, the lance 24 is in a state of being flexible. Therefore, the lance portion 24 is deflected by a lance portion locking release jig (not shown) or the like, and the electric wire 100 is pulled, whereby the male terminal fitting 12 can be pulled out of the male-side large cavity 22.

As described above, according to embodiment 1, the locking portion 67 is locked to the locking receiving portion 51, and the front stopper 16 moves from the locking position to the standby position in conjunction with the movement of the movable plate 15 from the fitting position to the initial position, so that the movement operation of the front stopper 16 to the standby position does not need to be independently performed, and workability is excellent.

Further, since the locking portion 67 is detachable from the locking receiving portion 51, when the movable plate 15 is located at the initial position, the locked state between the locking portion 67 and the locking receiving portion 51 is released, and the front stopper 16 can be moved from the standby position to the locking position. Therefore, even when the movable plate 15 is positioned at the initial position, the front stopper 16 reaches the locking position, and the restricting portion 65 is disposed in the deflection space of the lance portion 24, so that the double locking state of the male terminal fitting 12 can be achieved.

When the movable plate 15 is in the initial position, the jig 400 or the like is applied to the locking body 69 exposed on the front surface side of the movable plate 15 from the front of the cover 18, and the locking body 69 is disengaged from the locking surface 54, whereby the locked state of the locking portion 67 and the locking receiving portion 51 can be released. After the locking state of the locking portion 67 and the locking receiving portion 51 is released, the front stopper 16 can be brought to the locking position by pressing the front stopper 16 toward the housing 17 by the jig 400. When the connector 10 is not small, the locking state and the locking released state of the locking portion 67 and the locking receiving portion 51 can be checked from the front of the cover 18 through the locking hole 52 or by a sensor, and no special processing is required for the moving plate 15 and the front stopper 16.

Further, since the engaging portion 48 is engaged with the engaging receiving portion 92, and the movable plate 15 moves from the fitting position to the initial position in conjunction with the disengagement of the female housing 81 from the cover 18, it is not necessary to perform the operation of moving the movable plate 15 to the initial position independently.

Further, since the hooking portion 48 is disposed below the movable plate 15 and the locking receiving portion 51 is disposed above the movable plate 15, the hooking portion 48 and the locking receiving portion 51 can be formed with a high degree of freedom. Further, since the engaging portion 48 and the engaging receiving portion 51 are arranged in pairs in the width direction in the movable plate 15, the movable plate 15 and the front stopper 16 can be smoothly moved to the initial position and the standby position while maintaining balance, respectively.

[ other embodiments of the present disclosure ]

Embodiment 1 of the present disclosure is to be considered in all respects as illustrative and not restrictive.

In the case of embodiment 1, the front stopper has a coaxial restriction portion. However, as another embodiment, the following structure is also possible: the coaxial restriction portion may be omitted from the front stopper, and the front stopper may not lock the coaxial terminal in the second stage. In other words, the male housing may not house the coaxial terminal.

In the case of embodiment 1, the movable plate moves from the fitting position to the initial position in conjunction with the disengagement of the female housing. However, as another embodiment, the movable plate may be moved from the fitting position to the initial position without interlocking with the female housing. In this case, the following structure is also sufficient: when the movable plate moves from the fitting position to the initial position, the front stopper also moves from the locking position to the standby position.

In the case of embodiment 1 described above, the front stopper is partially formed so as to cover a part of the rear surface side of the plate main body of the movable plate. However, as another embodiment, the front stopper may be formed in a plate shape so as to cover the entire rear surface side of the plate body of the movable plate.
