    Technical field [0001]
    The present invention relates to a lever type connector coupling with a coupling connector by rotation of a lever.
    Prior art [0002]
    A connector of the lever type is generally known, provided with a lever and coupling with a coupling connector by rotation of the lever.
    [0003]
    In the lever type connector, coupling with the coupling connector begins in a state where the lever has been rotated to an uncoupled position in which the coupling connector is decoupled from the lever type connector. Then, the lever of the lever type connector is rotated from the uncoupled position to a coupled position in which the coupling connector is coupled with the lever type connector. Thus, depending on the rotation, the coupling connector is drawn into the lever type connector to be coupled therewith.
    [0004]
    Here, in the lever type connector, a locking portion is provided to maintain the coupled position of the lever which has been turned to the coupled position. In addition, in the lever type connector, a stop is provided to prevent the lever, which has been turned to the coupled position, from exceeding the coupled position. The stopper is arranged in a position at which the lever abuts on the stopper when the lever slightly exceeds a position at which the lever is locked by the locking part so that the lever turned towards the coupling position is firmly locked by the locking part. That is to say, there is a slight clearance between the locking part and the stop. Therefore, when the lever type connector vibrates, the lever in the coupled position rattles between the locking portion and the stopper, which may result in the appearance of abnormal noise.
    [0005]
    The PTL 1 patent literature discloses a lever-type connector which has a structure in which the appearance of abnormal noise is suppressed by suppressing clicks. That is, the lever type connector disclosed in the PTL 1 patent literature has an elastic arm portion disposed at the locking portion, and the clicking of the lever is suppressed by pressing the lever to the uncoupled position by means of a reaction force due to the elastic deformation of the elastic arm part.

    Patent literature [0006] PTL 1: JP2013-26154A Summary of the invention
    P rob1ème technique [0007]
    According to the lever type connector disclosed in the PTL 1 patent literature, the clicking of the lever is suppressed so that the occurrence of abnormal noise is suppressed.
    [0008]
    However, in the structure disclosed in the aforementioned PTL 1 patent literature, it is considered that the reaction force coming from the elastic arm is large in order to more effectively suppress the clicking of the lever. In the case where such a structure is adopted, when the coupled coupling connector is to be decoupled from the lever type connector, i.e. when the locked lever is unlocked from the locked state, there may be a problem. That is, as the reaction force from the elastic arm increases, greater force to unlock the lever is required. In other words, in the case of the structure disclosed in the PTL 1 patent literature, there may be a problem that it is difficult to balance both effective knock suppression and an appropriate force required to unlock the lever.
    [0009]
    In view of these circumstances, an object of the present invention consists in providing a connector of the lever type effectively suppressing the clicking of a lever and making possible an unlocking effected by a force having an appropriate amplitude.
    Solution to problems
    A lever type connector of the present invention for achieving the above object comprises:
    a lever support member; and a rotary lever which overlaps the lever support member in the width direction of the lever support member, the two end portions of the rotary lever being supported so as to be pivotable on the support member lever, and the rotary lever being rotated between an uncoupled position in which a coupling connector is decoupled from the lever type connector and a coupled position in which the coupling connector is coupled with the lever type connector, wherein the lever support member has:
    a locking part which grips the rotary lever which has been rotated in the coupled position in order to lock the rotary lever in the coupled position; and a biasing part pressed by the rotary lever which has been rotated into the coupled position so as to be elastically deformed and to bias the rotary lever towards the uncoupled part, and in which the locking part and the biasing part are arranged in mutually different positions in the width direction.
    [0011]
    In the case of the lever type connector of the present invention, the locking part and the biasing part are arranged in mutually different positions in the width direction. According to such a configuration, it is possible to prevent a structure for suppressing the clicking in the biasing part from affecting a locking structure in the locking part. Therefore, in accordance with the present invention, a lever type connector can be obtained in which the clicking of the rotary lever can be effectively suppressed, and uncoupling by force having an appropriate amplitude can be made possible.
    [0012]
    Here, in the lever type connector of the present invention, it is preferred that the biasing portion is disposed at a central portion of the lever support member in the width direction, and that the locking devices are arranged on both sides of the lever support member in the width direction.
    [0013]
    By arranging the biasing portion at the center portion in the width direction and arranging the locking portions on both sides of the biasing portion, a locking structure can be obtained having excellent balance in the direction of the width.
    [0014]
    Furthermore, in the lever type connector of the present invention, in a preferable aspect also, a housing is provided in addition to the lever support portion, and the lever support member is a wire cover in which an opening through which a wire is passed is formed between the wire cover and the housing, the wire cover forming a cover on the housing. [0015]
    The lever support member may be the housing itself, but in a lever type connector having the wire cover forming a cover on the housing, the wire cover may be used as the lever support member. Advantageous Effects of the Invention
    In accordance with the present invention described above, a lever type connector can be made in which the clicking of the lever is effectively suppressed and unlocking can be performed by means of a force having an appropriate magnitude.

    An embodiment of the present invention will be explained below.
    [0019]
    Figure 1 is a perspective view of a lever type connector of an embodiment of the present invention.
    [0020]
    In addition, Figure 2 is a perspective view of a wire cover and a rotary lever in the lever-type connector shown in Figure 1.
    [0021]
    Here, the rotary lever 40 shown in Figure 1 is located in a coupled position in which the lever type connector 10 shown in Figure 1 has been coupled to a mating connector (not shown). On the other hand, the rotary lever 40 shown in FIG. 2 is located in an uncoupled position in which the coupling connector has been decoupled from the connector of the lever type 10.
    [0022]
    The wire cover 30 has a dome shape which opens widely downwards (towards the side of a housing 20) and forms a bulge upwards. Then, an opening 11 through which many wires pass (not shown) is formed between the wire cover 30 and the housing 20. End portions of the many wires enter the opening 11, and they are connected to numerous contacts (not shown) supported by the housing 20.
    [0023]
    The rotary lever 40 extends in a shape substantially in the shape of an inverted U so as to overlap the wire cover 30 in the direction of the width of the wire cover 30. Holes 41 are formed at the two end parts of the rotary lever 40 On the other hand, projections 31 entering the holes 41 at the two end portions of the rotary lever 40 are formed on the two lateral faces of the wire cover 30, respectively. Then, the rotary lever 40 is turned around the projections 31 serving as the center of rotation between the coupled position shown in FIG. 1 and the uncoupled position shown in FIG. 2.
    [0024]
    The rotary lever 40 is formed with pinion gears 42 (see FIG. 3) around the holes 41. The pinion gears 42 mesh with racks (not shown) arranged on plate-shaped sliders (not shown) . The slides are inserted into slots 21 on both sides of the housing 20 one by one. Consequently, the slides are not exposed when the connector of the lever type appears 10. The slides are formed with cam tracks (not shown) including cam rollers (not shown) disposed on the connector inlet. appear.
    [0025]
    When coupling with the coupling connector, the rotary lever 40 is first rotated in the uncoupled position shown in Figure 2. Next, the coupling connector is arranged in an initial position for the coupling of so that the cam rollers of the coupling connector are placed in the entry parts of the cam tracks arranged in the sliders. In this state, the rotary lever 40 is rotated from the non-coupled position to the coupled position shown in Figure 1. Thus, the sliders formed with the racks slide as a function of the rotations of the pinion gears of the rotary lever 40 during the rotation of the rotary lever 40. Next, the cam rollers of the coupling connector are pushed deeper into the cam paths of the slides as a function of the sliding. The coupling connector couples with the lever type connector 10 as a function of the thrust depth.
    [0026]
    In the lever type connector 10, a locking portion, described later, is arranged so that the rotary lever 40 which has been rotated to the coupled position shown in Figure 1 maintains the coupled position. In addition, stops 32 are arranged on the two lateral faces of the wire cover 30. The rotary lever 40 which has been rotated in the coupled position abuts on the stops 32, thereby preventing the rotary lever 40 from going beyond the coupled position in being further turned. [0027]
    However, the stops 32 are arranged in positions in which the rotary lever 40 abuts on the stops 32 when the rotary lever 40 has been turned to a position in which the rotary lever 40 has slightly exceeded a position in which the rotary lever 40 is locked by the locking position so that the rotary lever 40 is more effectively locked by the locking portion. Consequently, the rotary lever 40 has a clearance between the position in which the rotary lever 40 has been locked by the locking part and the position in which the rotary lever 40 has been brought to abut on the stops. The lever type connector 10 can be used in an environment such that vibrations are applied to it, and in another lever type connector for which no action has been taken in particular, abnormal noise may appear due to a click of the rotary lever 40. Therefore, the lever type connector 10 of this embodiment is provided with a biasing portion for biasing the rotary lever 40 which has been locked in the coupled position towards the side of the uncoupled part. In accordance with the function of the biasing part, even if vibrations are applied to the lever type connector 10, the rotary lever 40 remains in the position in which the rotary lever 40 has been brought to abut on the locking part, so that the appearance of an abnormal sound is suppressed.
    [0028]
    As shown in FIG. 2, a biasing part on the cover side 33 and locking parts on the cover side 34 are arranged on the wire cover 30 in a position in which, when the rotary lever 40 has been turned in the coupled position, the cover -wire 30 is hidden by the rotary lever 40. The biasing part of the cover side 33 corresponds to an example of the biasing part in the present invention. In addition, the locking part on the cover side 34 corresponds to an example of the locking part in the present invention. The biasing part on the cover side 33 is arranged on the wire cover 30 in a central part in the width direction of the wire cover 30, while the locking parts on the cover side 34 are arranged on both sides of the biasing portion on the cover side 33 in the direction of the width of the wire cover 30, respectively.
    [0029]
    Figure 3 is a perspective view of the rotary lever.
    [0030]
    In FIG. 3, one can see a biasing part on the lever side 43 and locking parts on the lever side 44 arranged on the rotary lever 40. The biasing part on the lever side 43 is provided, at a central part , of an arm part of the rotary lever 40 extending in the direction of ίο the width of the wire cover 30. In addition, the locking parts of the lever side 44 are arranged on both sides of the biasing part of the lever side 43, respectively. That is to say, the lever-side biasing portion 43 and the lever-side locking portions 44 are arranged in positions corresponding to the biasing side of the shielding side 33 and the locking portions of the shielding side 34, respectively.
    [0031]
    Figure 4 is a cross-sectional view of the assembly of the wire cover and the rotary lever, taken along a plane extending along a plane of rotation of the rotary lever and crossing the biasing portion of the cover side and the biasing part on the lever side. [0032]
    Here, in Figure 4 (A), there is shown the rotary lever 40 located in the uncoupled position. In addition, in Figure 4 (B), there is shown the rotary lever 40 located in the coupled position.
    [0033]
    As shown in Figure 2, the biasing side of the cover side 33 is disposed at a distal end portion of a portion of the wire cover 30 formed between cutouts 35 located on both sides of the wire cover 30 and extending in the manner of a cantilever. Then, a leading edge portion of the distal end portion is formed with a raised portion 331 projecting upward.
    [0034]
    On the other hand, the lever side biasing portion 43 also extends in the manner of a cantilever. Then, when the rotary lever 40 is rotated in the coupled position, a portion 431 close to the distal end of the biasing portion on the lever side 43 extending in the manner of a cantilever abuts the raised portion 331 of the biasing part on the cover side 33. Thus, the biasing part on the cache side 34 is pressed to be elastically deformed by the biasing part on the lever side 43. Then, the rotary lever 40 is put in a state where it was biased towards the side of the uncoupled position by a reaction force due to elastic deformation of the biasing part on the cover side 33.
    [0035]
    Figure 5 is a cross-sectional view of the assembly of the wire cover and the rotary lever, taken along a plane extending along the plane of rotation of the rotary lever and crossing the locking part on the cover side and the locking part on the lever side. [0036]
    Here, in FIG. 5 (A), the rotary lever turned in the uncoupled position is shown. In addition, in Figure 5 (B), there is shown the rotary lever located in the coupled position.
    [0037]
    A hook portion on the cover side 341 is disposed on the locking portion on the cover side 34. On the other hand, a hook portion on the lever side 441 is also disposed on the locking portion on the lever side 44. Then, when the rotary lever 40 is turned to a position just before the coupled position, the hook part on the cover side 341 is pressed downwards by the hook part on the lever side 441 so that the locking part on the cover side 34 is elastically deformed Once. Then, when the rotary lever 40 is rotated to the coupled position shown in Figure 5 (B), the locking portion of the cover side 34 recovers from the elastic deformation. Then, as shown in Figure 5 (B), the hook side hook portion 341 and the hook side hook portion 441 are engaged with each other. Thus, the rotary lever 40 is locked in the coupled position.
    [0038]
    The rotary lever 40 located in the coupled position is biased towards the uncoupled position by the biasing part on the lever side 43 (see FIG. 4) by being pressed by the biasing part on the cover side 33. Consequently, even when the lever type connector 10 is placed in a vibration environment, it is maintained in a state such that the hook part on the lever side 441 is always pressed on the hook part on the cover side 341. Namely, the rotary lever 40 is held in a position which is always spaced from the stops 32, so that an abnormal noise generated because the rotary lever 40 stops on the stops 32 is prevented from occurring.
    [0039]
    Here, as shown in FIG. 2, both the biasing portion on the cover side 33 and the locking portions on the cache side 34 located on both sides of the biasing portion on the cache side 33 are located inside between the cutouts. 3 5 on both sides, and they form a one-piece overhang. However, the biasing part on the cache side 33 is situated on the side of the distal end extending so as to be longer than the locking parts on the cache side in the form of a cantilever 34. Namely, the biasing portion on the cover side 33 and the locking portions on the cover side 34 have a length different from that of the overhang shape. In addition, the biasing side on the cover side 33 and the locking side side locking portions 34 also have mutually different shapes. Thus, the biasing part composed of the biasing part on the cover side 33 and the biasing part on the lever side 43 generates a biasing force with an appropriate amplitude. Furthermore, in the locking part composed of the locking parts on the cover side 34 and the locking part on the lever side 44, the locking and unlocking can be effected with an appropriate force.
    [0040]
    Thus, in the present embodiment, the biasing part composed of the biasing part on the cover side 33 and the biasing part on the lever side 43 and the locking part composed of the locking parts on the cache side 34 and the parts for locking the lever side 44 are arranged in mutually different positions in the direction of the width of the wire cover 30. Thus, the biasing part and the locking part can be formed so that optimum forces are applied to them, respectively.
    [0041]
    Furthermore, in the present embodiment, the biasing portion is disposed at the central portion in the direction of the width of the wire cover 30, and the locking portions are disposed on both sides of the biasing portion so that the biasing part is located between the two sides. Thus, the lever type connector 10 of this embodiment achieves a well balanced structure in the width direction with respect to both form and function.
    [0042]
    It should be noted that the lever type connector 10 has been explained here in the case where the wire cover 30 is present, and the wire cover 30 is an example of the lever support member in the present invention. However, the lever support member in the present invention is not limited to the wire cover 30. In a connector having a configuration which does not include the wire cover, for example, the lever support member in the present invention may have a structure in which the rotary lever is mounted so as to be able to pivot on the housing itself in a rotary manner, and the biasing part and the locking part are formed on the housing itself .
