It is the sectional view on the AA line of FIG. 1 which shows the state before fitting of a female connector and a male connector. It is the BB sectional drawing of FIG. 2 which shows the state after a female connector and a male connector fitting. It is a figure which shows an example of the conventional connector.

  A connector device according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. Although the waterproof connector will be described as an example, the present invention can be applied to various types of connector devices other than the waterproof connector.

  In FIG. 1, the perspective view of the connector apparatus 1 of this invention is shown. This connector main device 1 includes a female connector 10 and a male connector 70. The female connector 10 is used by being connected to one end of the electric cable 3, while the male connector 70 is used by being installed on the surface of a housing (not shown) of a motor or other device. Both can be fitted to each other by being brought close to the fitting direction (the arrow “Y” direction in the figure). FIG. 1 shows a state before the fitting, and FIGS. 2 and 3 show a state after the fitting in a front perspective view and a side perspective view, respectively. For example, when it is desired to detach the male connector 70, the fitting of the female connector 10 and the male connector 70 can be released, and once they are removed from the housing, they can be attached to the housing again.

  When the female connector 10 and the male connector 70 are fitted into a state as shown in FIGS. 2 and 3, the female connector 10 is attached to the male connector 70 in order to maintain the fitted state between them. It can be locked. In order to enable locking, an arm portion (locking portion) 50 is provided on the female connector 10 side, and a locking member (locked portion) 80 is provided on the male connector 70 side. In addition, the latching | locking part by the side of the female connector 10 can also be replaced with the groove | channel provided in the arm part so that it may mention later. In any case, the arm portion 50 and the groove are part of the operation lever 40 and move together with the operation lever 40. FIGS. 4 and 5 are views corresponding to FIGS. 2 and 3, respectively, and show a state in which the operation lever 40 is moved and the arm portion 50 is locked to the locking member 80. . While mainly focusing on the operation lever 40 (or the arm portion 50), the female connector 10 is locked with respect to the male connector 70, as is apparent from a comparison between FIGS. In this case, the arm portion 50 formed as a part of the operation lever 40 is inserted into a through hole 83 formed by a part of the insulating housing 20 of the female connector 10 and a part of the insulating housing 72 of the male connector 70. Insert. By inserting the arm part 50 through the through hole 83, even if a force for separating the female connector 10 and the male connector 70 is applied, the arm part 50 of the female connector 10 is more accurately Since the engaging member 80 of the male connector 70 that forms the through hole 83 is caught, the fitting state of the female connector 10 and the male connector 70 is not easily released.

  Next, the structure of the female connector 10 and the male connector 70 will be described in detail with reference to FIGS. 6 is an exploded perspective view of the female connector 10 and the male connector 70 shown in FIG. 1 and the like, and FIG. 7 is a cross-sectional view taken along line AA of FIG. 1 showing a state before the female connector 10 and the male connector 70 are fitted together. 8 is a cross-sectional view taken along line BB of FIG. 2 showing a state after the female connector 10 and the male connector 70 are fitted together. The female connector 10 and the male connector 70 are both symmetrical.

  First, the female connector 10 will be described. The female connector 10 includes an insulating housing 20, a clamp rubber 13 and a clamp 15 for fixing the electric cable 3 to the insulating housing 20, a resin operation lever 40 that is rotatably supported on the outer wall of the insulating housing 20, an insulating member. From the bottom side of the housing 20, that is, from the bottom side of the insulating housing 20 with the shield case 16 housed in the insulating housing 20 from the mating side between the female connector 10 and the male connector 70, with the top covered by the shield case 16. The terminal case 60 is accommodated, and further includes a plurality of terminals 65 and a ground terminal 66 arranged in the terminal case 60 through terminal holes 61 provided in the terminal case 60.

  The insulating housing 20 has a substantially rectangular box shape in which the front upper part is a smooth curved surface. The reason why the upper part of the front side is a curved surface is that the rotation of the operation lever 40 is not hindered. The rear side and the bottom side of the insulating housing 20 are opened to attach the electric cable 3 and accommodate the shield case 16 and the terminal case 60, respectively. A clamp piece 28 extends on the rear side of the insulating housing 20 so that the electric cable 3 can be attached. The electric cable 3 inserted through the clamp rubber 13 is inserted into the clamp piece 28, and the clamp 15 is attached so that the clamp piece 28 surrounds the outside, whereby the electric cable 3 can be fixed to the insulating housing 20.

  Hooks 39 for hooking the female connector 10 to the male connector 70 are provided on the left and right side outer walls on the bottom side of the insulating housing 20. When the female connector 10 and the male connector 70 are fitted, a part of the locking member 80 of the male connector 70 (the overhanging portion 82) is hooked on the hooking portion 39 of the female connector 10, whereby the female connector 10 Is lightly locked to the male connector 70.

  A rotating shaft 21 is provided outward in the vicinity of the center of each of the left and right side surfaces of the insulating housing 20. Corresponding to these rotating shafts 21, shaft holes 46 through which the rotating shaft 21 is inserted are formed on the left and right side surfaces of the operation lever 40. By inserting the rotating shaft 21 of the insulating housing 20 through the shaft hole 46 of the operating lever 40, the operating lever 40 is rotatably supported by the insulating housing 20. At this time, the operation lever 40 is stretched across the both side surfaces of the insulating housing 20 through the front surface of the insulating housing 20. By spanning the operating lever 40 over the insulating housing 20, the operating lever 40 occupies a larger range in the insulating housing 20. As a result, the operability of the operating lever 40 is improved, and further, the insulating housing 20 is further improved. The user can easily grasp the position of the operation lever 40 in FIG. In particular, in this configuration, the operating lever 40 is rotated only after the female connector 10 and the male connector 70 are fitted, or the male connector 70 is pulled toward the female connector 10 by rotating the operating lever 40. Since the connector 10 and the male connector 70 are completely fitted, whether or not the female connector 10 and the male connector 70 are completely fitted is determined by determining the position of the operation lever 40. Alternatively, it is possible to grasp at a glance whether or not the locking is complete. In addition, when the plate | board thickness of the arm part 50, in other words, when the dimension of the arm part 50 in the direction away from the insulating housing 20 is increased, the cam groove 144 shown in FIG. A groove can be provided, and locking can be performed using this groove. Of course, in this case, the shape of the locked portion 80 needs to be slightly changed in accordance with the shape.

  In order to further improve the operability of the operation lever 40, an operation unit 42 may be provided at the center. The user can easily operate the operation lever 40 by hooking a finger on the operation unit 42 or the like. When the operation lever 40 is rotated with respect to the insulating housing 20, it is convenient if the operation lever 40 can be temporarily fixed at a predetermined position of the insulating housing 20. In order to perform temporary fixing, a linear holding projection 47 is provided on the inner wall near the shaft hole 46 of the operation lever 40, and correspondingly, the left and right side outer walls of the insulating housing 20 are cross-shaped. A holding groove 27 is provided near the base of the rotating shaft 21. The operation lever 40 is rotated with respect to the insulating housing 20, and the holding protrusion 47 provided on the operation lever 40 and the holding groove 27 provided on the insulating housing 20 are lightly combined to temporarily fix the operation lever 40 at a predetermined position. be able to.

  Even if temporary fixing is possible, if no means are provided, the operating lever 40 will rotate to the bottom side of the insulating housing 20, more specifically, to the fitting side between the female connector 10 and the male connector 70. Let's go. In order to restrict excessive rotation of the operation lever 40 downward, a rotation restricting means may be provided. The rotation restricting means is provided at the center of the operation lever 40 and protrudes toward the bottom, and correspondingly, protrudes toward the front provided at the bottom of the front wall of the insulating housing 20. It consists of a stopper 23. When the operation lever 40 tries to rotate excessively, the front side restricting portion 43 and the stopper 23 collide with each other, so that the operation lever 40 is not pushed down beyond the collision position.

  When the operation lever 40 is completely pushed down, it is convenient that the operation lever 40 can be temporarily fixed so as not to move upward. In order to temporarily fix the operation lever 40, a locking projection 25 that can be elastically deformed may be provided near the center of the front wall of the insulating housing 20. When the operation lever 40 is pushed down, the operation portion inner wall 42 ′ of the operation lever 40 is caught by the locking projection 25, thereby preventing the operation lever 40 from moving upward. This temporarily fixed state is further strengthened by temporary fixing by the holding protrusion 47 of the operation lever 40 and the holding groove 27 of the insulating housing 20 described above.

  In order to lock the female connector 10 to the male connector 70, a part of the operation lever 40 is formed as an arm portion 50 reinforced by a rib 45. Since the female connector 10 is symmetrical, the arm portion 50 is disposed on each side surface of the insulating housing 20. Each arm portion 50 is curved along the rotation direction of the operation lever 40 so as to surround a part of the outer periphery of the shaft hole 46. The distal end of the arm part 50 is a free end 51, and when the operation lever 40 is rotated, the arm part 50 is part of the insulating housing 20 of the female connector 10 and part of the insulating housing 72 of the male connector 70. Are inserted from the free end 51 side. As a result, the arm portion 50 is locked at a portion other than the free end 51 by the through hole 83, more precisely, the locking member 80 of the male connector 70 forming the through hole 83.

  Support portions 30 for supporting the vicinity of the free end 51 of the arm portion 50 are provided on the left and right side outer walls of the insulating housing 20. When a force is applied in a direction in which the female connector 10 and the male connector 70 are separated, the free end 51 of the arm portion 50 is deformed toward the locking member 80 with the base portion of the arm portion 50 inserted through the locking member 80 as a fulcrum, As a result, a large force is applied near the base. As a result, if no countermeasures are taken, the arm part 50 is easily deformed and may be damaged. In order to prevent the deformation of the arm portion 50, the arm portion 50 is at least near the free end 51 at the tip of the locking portion with the locking member 80, and is opposite to the side of the arm portion 50 that faces the rotating shaft 21. The support part 30 which supports the arm part 50 is provided in the outer peripheral surface of 54, etc. As a result, the arm portion 50 that has received excessive force is prevented from spreading, the locking state between the arm portion 50 and the locking member 80 is maintained, and the female connector 10 and the male connector 70 are fitted. The combined state can be maintained. Note that a curved surface 31 corresponding to the curvature of the arm portion 50 may be formed on the surface of the support portion 30 on the fitting side between the female connector 10 and the male connector 70. By forming such a curved surface 31, the arm portion 50 can be supported and the deformation of the arm portion 50 can be prevented more reliably.

  Next, the male connector 70 will be described. The male connector 70 includes an insulating housing 72 and an upper side of the insulating housing 72, in other words, a waterproof gasket 75 attached to a fitting side between the female connector 10 and the male connector 70, and a bottom side of the insulating housing 72. Then, the terminal case 90 attached to the housing (not shown) side of the motor or other device on which the male connector 70 is installed, and further arranged in the terminal case 90 with the tip 96 protruding through the terminal hole 91. A plurality of terminals 95 are included.

  The insulating housing 72 includes a flange portion 71 that forms a mating face of the female connector 10 and the male connector 70, a fitting portion 78 provided in a state of protruding above the flange portion 71, and a flange portion 71. And a locking member 80 having a substantially inverted L shape when viewed from the side, provided on the left and right sides of the fitting portion 78. However, in actual use, the locking piece 73 and the like on the bottom side of the flange portion 71 is installed inside a housing (not shown) of a motor or other device and cannot be seen from the outside. The flange portion 71 may be placed on the surface of the housing, but may be configured as a part of the surface of the housing.

  When the female connector 10 and the male connector 70 are fitted, the fitting portion 78 is accommodated in the fitting portion formed on the bottom side of the insulating housing 20 of the female connector 10. A slight gap is generated between the inner wall 37 and the fitting portion 78 of the male connector 70. In order to fill this gap, a gasket 75 is attached to the fitting portion 78. To facilitate attachment, an annular groove 74 is formed on the outer periphery of the fitting portion 78. The gasket 75 is made of rubber and has an elastic action. By using this elastic action, the gasket 75 can be fitted in a state of being in close contact with the groove 74.

  As one of the conventional general waterproof structures, waterproof means such as a gasket is sandwiched between the mating surface between the female connector and the male connector, and the female connector and the male connector are screwed to the mating surface. There is a type that crushes waterproof means. However, in this type of waterproof structure, when the cable connected to the male connector or the female connector is pulled, the positional relationship between the male connector and the female connector is shifted, thereby preventing the force to crush the waterproof means. As a result, there was a problem that a gap was formed on the fitting surface and the waterproof function was lowered. On the other hand, in this structure, since the fitting state is maintained by the locking structure using the arm portion 50, it is not necessary to screw the female connector 10 and the male connector 70, and therefore, screw tightening and torque management are not required. No need to worry about loose screws. Further, since the waterproof means is disposed so as to fill the gap between the fitting portion 38 of the female connector 10 and the fitting portion 78 of the male connector 70, the positions of the female connector 10 and the male connector 70 are slightly shifted. Even if it is, the waterproof function is maintained.

  The locking piece 73 is used for attaching the terminal case 90 to the insulating housing 72. A locking projection 77 is provided at the front end of the locking piece 73 toward the inside. The locking projection 77 is formed in a locking recess 97 provided on each of the left and right side outer walls of the terminal case 90. By hooking, the terminal case 90 can be locked to the locking piece 73.

  The locking member 80 is continuous with the upright portion 81 from the flange portion 71 to the fitting side of the female connector 10 and the male connector 70, and is continuous with the upright portion 81 so as to cover the female connector 10 side of the arm portion 50. It is formed from an overhanging portion 82 that overhangs. The upright portion 81 is disposed so as to be positioned outside the arm portion 50 provided in the female connector 10 when the female connector 10 and the male connector 70 are fitted. By arranging the upright portion 81 on the outside of the arm portion 50 in this manner, it is not necessary to provide a locking member in the fitting portion 78, and the height of the connector device can be reduced. The overhanging portion 82 is bent so as to match the bending of the arm portion 50.

Finally, the operation of the connector device 1 will be described.
As apparent from a comparison between FIGS. 1, 7 and FIGS. 2, 3, and 8, when the female connector 10 and the male connector 70 are fitted, the male connector is connected to the male connector 10 from the bottom of the insulating housing 20. The fitting portion 78 of the female connector 10 is inserted, and the bottom side of the terminal case 60 of the female connector 10 is inserted into the terminal case housing portion 76 of the insulating housing 72 of the male connector 70. As a result, the terminals 65 and the ground terminal 66 arranged in the terminal case 60 of the female connector 10 are connected to each other in a state where the tip 96 of the terminal 95 provided in the terminal case housing portion 76 of the male connector 70 is sandwiched. Is done. Further, at this time, the hook portion 39 of the female connector 10 is hooked on a part of the locking member 80 of the male connector 70, that is, the overhang portion 82, and the fitting of the female connector 10 and the male connector 70 is fixed. . Note that the terminal structure of the female connector 10 and the male connector 70 is symmetrical in the front-rear direction, that is, the mounting side of the operation lever 40, and the rear side, that is, the mounting side of the electric cable 3, so In addition, the orientation of the female connector 10 and the male connector 70 can be rotated 180 degrees.

  After fitting the female connector 10 and the male connector 70, the operation lever 40 is rotated about the rotation shaft 21 of the insulating housing 20. As a result, as shown in FIGS. 4 and 5, the arm portion 50 which is a part of the operation lever 40 is formed by a part of the insulating housing 20 of the female connector 10 and a part of the insulating housing 72 of the male connector 70. The inserted through hole 83 is inserted. At this time, a part of the arm portion 50 other than the free end 51 is locked by the locking member 80, and the free end 51 of the arm portion 50 is supported by the support portion 30 of the female connector 10. Therefore, even when a force is applied in a direction in which the female connector 10 and the male connector 70 are separated from each other, not only a part of the arm portion 50 locked by the locking member 80 exerts a drag, but also this one. As a fulcrum, the base part of the arm part 50 and the free end are in a doubly supported beam state, and even when a force is applied near the free end 51 of the arm part 50, the arm part is prevented from spreading to the male connector 70 side. The locking state between the arm portion 50 and the locking member 80 can be maintained, and the fitting state of the female connector 10 and the male connector 70 can be maintained.

  The present invention can be widely applied to various connectors that maintain the fitted state using the arm portion.
