That is, the connectors connected to both ends of the wires of the wire harness are connected to the device terminals of each electrical device, whereby the electrical devices are electrically connected. As this type of connector, there is one disclosed in Patent Document 1.

  In the connector of Patent Document 1, a flange is formed in a cylindrical housing that holds a plurality of connector terminals, and this flange is fixed to a mounting surface of a housing that accommodates an electrical device to be connected. The connector fixed to the mounting surface of the housing is inserted so that one end of the connector terminal is inserted into the housing and connected to the equipment terminal in the housing, while the other end of the connector terminal is connected to the wire of the wire harness. It has become.

JP 2012-195068 A

  By the way, as for the connector described in patent document 1, the some connector terminal is connected by the fastening of the apparatus terminal and the volt | bolt, respectively. However, equipment terminals (terminal blocks) of electric devices mounted on vehicles and the like are often provided in the housing, and it is necessary to perform bolting work in the housing. Since this work is performed by inserting a tool into a narrow space in the housing, the burden on the operator is large, and the work man-hour is increased. In addition, since this type of connector is connected to the wires of the wire harness, it is necessary to secure a space for routing the wires between the electrical devices, making it difficult to save space between the electrical devices. Yes.

  On the other hand, the connection structure of a male terminal and a female terminal is known as a connection structure of the terminal which does not perform the bolt fastening operation. For example, the male terminal is held inside the female terminal by being inserted into the cylindrical female terminal and then pressed by the female terminal. However, this type of connection structure has a problem in that since the insertion load when inserting the male terminal into the female terminal is increased, the work load at the time of terminal connection is increased, and the work efficiency is reduced.

  The present invention has been made in view of these problems, and it is an object of the present invention to realize a space saving between electrical devices, to improve work efficiency of connector connection work, and to reduce work man-hours.

  In order to solve the above-described problems, a connector of the present invention includes a connector housing and a connector terminal held by the connector housing, and is a connector for connecting the connector terminal to a device terminal of an electrical device. It is held at a position where it can come into contact with a device terminal inserted relative to the housing, and is rotatably supported by the connector housing, and has a cam that presses and contacts the contact portion of the connector terminal and the device terminal. And

  According to this, since the device terminals can be connected to each other with one connector, no electric wire is required, and space saving between the electrical devices can be realized. For example, among the device terminals of two electrical devices, one device terminal is connected to the connector terminal, and the cam is rotated with the other device terminal inserted into the connector housing. Thereby, between apparatus terminals can be connected with a connector terminal.

  Further, if the connector of the present invention is used, the connector terminal and the equipment terminal can be connected outside the housing of the electrical equipment, so that a wide space for connection work can be secured, and the camshaft The connector terminal and the device terminal can be connected by a simple operation of rotating. Therefore, the connection work can be performed efficiently, and the work man-hours can be reduced.

  Further, in the present invention, the contact portion of the connector terminal and the device terminal are brought into close contact with each other by pressing the cam so that the contact portion of the connector terminal is inserted into the connector housing. It can arrange | position in the position away from. As a result, the device terminal can be inserted into the connector housing in a non-contact (no load) state, so that the burden of connection work can be reduced, and damage due to contact between the device terminal and the connector terminal can be prevented. be able to.

  In this case, the cam can be supported by the camshaft, and the camshaft can be formed to be rotatable by a rotation operation unit supported by the connector housing. According to this, the operability of the cam can be further enhanced.

  Moreover, it can have an elastic member that urges a portion of the connector terminal with which the cam abuts toward the cam.

  According to this, for example, when the camshaft is rotated in the reverse direction, the connector terminal moves in a direction away from the device terminal by the reaction force (restoring force) of the elastic member, so that the connection state between the device terminal and the connector terminal is Can be easily released.

  In addition, when the protrusion protruding from the outer peripheral surface of the camshaft rotates and moves to the set position, a rotation restricting portion that stops the rotation of the camshaft by contacting the protrusion can be provided.

  According to this, since the cam can always be rotated to the normal position by appropriately setting the position where the projection portion comes into contact with the rotation restricting portion, the connection between the connector terminal and the device terminal is ensured. This can be done and the reliability of the connector can be increased.

  In addition, the rotation operation part is formed in a columnar shape, and has an elastically deformable lock part that locks the rotation of the engagement part protruding from the outer peripheral surface of the rotation operation part. When it is pressed by the locking part, it is elastically deformed to a position where the locking part can get over, and when the rotation operation part reversely rotates, it makes contact with the locking part and prevents reverse rotation of the rotation operation part It can be.

  According to this, since the reverse rotation of the camshaft can be suppressed, the connection state between the connector terminal and the device terminal can be maintained, and the reliability of the connector can be further improved.

  The contact portion is formed to have a bent first contact piece and a pressing portion that is connected to the first contact piece and contacts the cam, and the device terminal has the first contact piece of the cam. It has a 2nd contact piece arrange | positioned in the path | route which moves by press, and this 2nd contact piece shall be bent and formed so that a 1st contact piece can slide.

  According to this, the contact portion of the connector terminal is separated from the device terminal inserted into the connector housing because the bent first contact piece is brought into contact with the second contact piece of the device terminal by the rotation of the cam. Can be placed at different positions. Moreover, since the oxide film formed on these surfaces can be removed by friction between the first contact piece and the second contact piece, electrical contact reliability can be improved.

  In this case, either one of the first contact piece and the second contact piece may have a protruding conductive contact that is elastically deformed when contacting the other.

  According to this, since the displacement between the first contact piece and the second contact piece can be absorbed by the contact, the electrical contact reliability can be further improved.

  The rotation operation unit includes a plate-like member that is supported by the camshaft and rotates. A cam groove is formed in one of the plate-like member and the member that is relatively inserted into the connector housing, and the other is a cam. The convex part engaged with a groove | channel is provided, and a cam groove shall be formed so that conversion of the linear motion of a convex part into the rotational motion of a camshaft is possible.

  According to this, since the camshaft can be rotated simply by inserting the member into the connector housing, an operation for rotating the camshaft becomes unnecessary, and the assembling workability can be improved.

  According to the present invention, space saving between electrical devices can be realized. Further, according to the present invention, it is possible to increase the work efficiency of the connector connection work and reduce the work man-hours.

That is, the contact portions 38 facing the cam 29 are provided on both sides of the cam 29 in the front-rear direction.

  Next, the detailed configuration and operation of the cam mechanism of this embodiment will be described. FIG. 6 shows the cam rotation angle in three stages with respect to the cross section of the cam in the front-rear direction of the connector.

  As shown in FIG. 6A, terminal support portions 33 are disposed on both sides of the cam 29 in the front-rear direction, and the contact portions 38 of the connector terminals 18 supported by the terminal support portions 33 are raised upward. Provided. The device terminals 27 are inserted into the respective terminal support portions 33 from the openings 51 substantially in parallel with the contact portions 38. The device terminal 27 inserted into the opening 51 is arranged such that the surface facing the contact portion 38 is separated from the contact 42. Further, the surface of the device terminal 27 opposite to the contact portion 38 is in contact with the side wall 53 of the holder cover 32 or is disposed in the vicinity of the side wall 53.

  Each contact part 38 is arranged so that part or all of the contact part 38 is hidden below the top plate 52 when the terminal support part 33 is viewed from above. In FIG. 6A, each contact portion 38 is in contact with the flat surface of the cam 29. A chamfer 54 is provided at an upper end portion of each contact portion 38 along at least a corner portion on the device terminal 27 side. Further, on the surface of the side wall 53 on the device terminal 27 side, a tapered surface 55 that guides the device terminal 27 to the terminal support 33 and an elastic member (elastic arm 56) that extends obliquely downward are provided. The elastic arm 56 is formed integrally with the holder cover 32 and is elastically deformable at least in the front-rear direction. The elastic arm 56 is positioned below the device terminal 27, and always presses the raised contact portion 38, which is a portion with which the cam 29 of the connector terminal 18 abuts, and biases it toward the cam 29. Yes.

  The terminal support portion 33 is set to a predetermined dimension in which the distance between the contact 42 and the side wall 53 is larger than the thickness of the device terminal 27. This set dimension is a sufficient distance so that the device terminal 27 inserted into the terminal support portion 33 does not come into contact with the contact portion 38 (contact 42) in consideration of variations in the insertion position of the device terminal 27 in the front-rear direction. Is secured. Thereby, the device terminal 27 is inserted into the terminal support portion 33 without contacting the contact portion 38.

  On the other hand, as shown in FIG. 6A, the outer peripheral surface of the cam 29 is a pair of parallel flat surfaces (hereinafter referred to as the first flat surface 57) that come into contact with the contact portions 38 on both sides, and FIG. As shown in FIG. 6 (c), FIG. 6 (a) is rotated 90 degrees to have a pair of parallel flat surfaces (hereinafter referred to as second flat surfaces 58) that are in contact with the two contact portions 38, respectively. Formed. The first flat surface 57 and the second flat surface 58 are connected by an arcuate curved surface. The distance between the flat surfaces of the second flat surface 58 is set to be larger than the distance between the flat surfaces of the first flat surface 57, and from the rotation center of the cam 29 to the contact point where the cam 29 contacts each contact portion 38. Is set so as to increase continuously from FIG. 6A to FIG. 6C.

  In such a configuration, the device terminal 27 is inserted into the terminal accommodating portion 36 along the side wall 53, for example. Thereby, as shown in FIG. 6A, the device terminal 27 is disposed in the terminal accommodating portion 36 in a fashion that contacts the side wall 53, for example.

  Next, when the tool is engaged with the head portion 46 of the operation member 30 and the operation member 30 is rotated forward in the direction of the arrow, the cam 29 is rotated in the direction of the arrow together with the camshaft 28. Then, the contact portions 38 on both sides contacting the first flat surface 57 of the cam 29 are respectively pressed by the cam 29 and elastically deformed. Thereby, each contact part 38 begins to move in a direction away from each other, that is, a direction approaching the device terminal 27. In the present embodiment, since the cross-sectional shape of the cam 29 is formed point-symmetrically with respect to the rotation center, the two contact portions 38 move by the same distance as the cam 29 rotates.

  FIG. 6B shows a state where the curved surfaces connecting the first flat surface 57 and the second flat surface 58 are in contact with both contact portions 38. At this time, the contact 42 of the contact portion 38 is not yet in contact with the device terminal 27.

  When the operation member 30 is further rotated forward, the distance between the contact portion 38 and the rotation center of the cam 29 is further increased, and finally the second flat surface 58 of the cam 29 is moved as shown in FIG. The contact part 38 is pressed. That is, each contact 42 presses the device terminal 27. Accordingly, all the device terminals 27 are sandwiched between the side wall 53 and the contacts 42 and are electrically connected to the connector terminals 18 respectively. Even if the device terminal 27 inserted into the terminal support portion 33 is not in contact with the side wall 53, if the device terminal 27 is pressed by the contact portion 38, the device terminal 27 is deformed to the side wall 53 side. And the contact portion 38, the device terminal 27 is sandwiched.

  In the present embodiment, the timing of stopping the rotation of the operation member 30 can be determined by the change in torque when the second flat surface 58 comes into contact with the contact portion 38. In addition, since the contact portion 38 is provided with a contact 42 that bulges toward the device terminal 27, variations in the positions of the device terminal 27 and the contact portion 38, that is, variations in the distance between the device terminal 27 and the contact portion 38. Can be absorbed. Thereby, the apparatus terminal 27 and the contact part 38 can be reliably connected, and the connection state can be maintained.

  On the other hand, when the connection between the device terminal 27 and the connector terminal 18 is released, the rotation direction of the operation member 30 is reversed from the state shown in FIG. At this time, since the contact portion 38 is urged toward the cam by the elastic arm 56, the contact portion 38 moves away from the device terminal 27 in accordance with the rotation of the cam 29 and returns to the state shown in FIG. be able to.

  By the way, the camshaft 28 of this embodiment is always loaded in the reverse rotation direction by the reaction force of the elastic arm 56, for example. As a result, the cam 29 cannot maintain the state of FIG. 6C and causes reverse rotation, and the connection state between the device terminal 27 and the connector terminal 18 may be released naturally.

  In this regard, as shown in FIG. 3, the cam mechanism of the present embodiment locks the four locking portions 59 a to 59 d protruding from the outer peripheral surface of the columnar operation member 30 and the rotation of the locking portion 59. And a locking mechanism. The locking portions 59 a to 59 d are provided at 90 ° intervals in the circumferential direction of the outer peripheral surface of the body portion 47 of the operation member 30. The locking mechanism is provided along the periphery of the through hole 45 outside the connector housing 15, and has a pair of locking members 60a and 60b extending substantially parallel to each other.

  The pair of lock members 60 a and 60 b are resin members formed integrally with the connector housing 15. The lock members 60a and 60b are both supported by the connector housing 15 in a cantilever manner. The lock member 60a is formed to extend upward, while the lock member 60b is formed to extend downward. Hooks 61 for locking the locking portions 59 are provided at the distal ends of the lock members 60.

  FIG. 7 is a cross-sectional view of the operation member 30 along the rotation direction, and FIGS. 7A to 7C correspond to FIGS. 6A to 6C, respectively. In FIG. 7A, the locking portions 59b and 59d are in contact with the lock members 60a and 60b, respectively.

  When the operating member 30 is normally rotated in the direction of the arrow from this state, the locking portions 59a to 59d are rotated, and the locking portions 59a and 59c are respectively connected to the locking members 60a and 60b through FIG. It contacts the hook 61. Each hook 61 is formed with a tapered surface 62 at a position where the locking portion 59 that rotates forward is in contact, and the locking portions 59 a and 59 c are in contact with the tapered surface 62.

  Further, when the operation member 30 is rotated forward, the locking portions 59a and 59c press the lock members 60a and 60b while moving (sliding) along the tapered surfaces 62 of the hooks 61, respectively. Thereby, the locking members 60a and 60b are pressed by the locking portions 59a and 59c, respectively, and elastically deform in a position where the locking portions 59a and 59c can get over, that is, in a direction away from the rotation center of the operation member 30. As a result, the locking portions 59a and 59c rotate over the lock members 60a and 60b and stop in the state shown in FIG.

  In FIG. 7C, the locking portions 59a and 59c are in contact with the hooks 61 of the lock members 60a and 60b, respectively, but the surface of the hook 61 with which the lock members 60a and 60b are in contact is formed with a tapered surface 62. Such an inclined surface is not formed. For this reason, the torque for elastically deforming the lock members 60a, 60b to the position where the locking portions 59a, 59c can push over the lock members 60a, 60b from the reverse rotation direction to overcome the lock members 60a, 60b from the positive rotation direction. It is much larger than the torque when getting over by pressing.

  With such a configuration, in the state of FIG. 7C, unless the operating member 30 is rotated in the reverse rotation direction by an external force other than the elastic arm 56, the locking portions 59a and 59b are engaged by the lock members 60a and 60b. It remains stopped and does not rotate in the reverse direction. Therefore, since the reverse rotation of the cam 29 can be suppressed by the lock portions 60a and 60b, the connection state between the connector terminal 18 and the device terminal 27 can be maintained, and the reliability of the connector can be further improved.

  Next, a structure that regulates the amount of rotation of the camshaft 28 in the cam mechanism of this embodiment will be described. As shown in FIG. 3, restriction cams 63 are supported at both ends of the camshaft 28. Each regulating cam 63 is formed in the same shape as each other, and has a protruding portion 64 protruding from the outer peripheral surface of the camshaft 28 in the same setting direction. On the other hand, the holder cover 32 is formed with receiving portions 65 for receiving each regulating cam 63 in a non-contact manner on both sides in the left-right direction.

  FIG. 8 is a cross-sectional view of the accommodating portion 65 along the rotational direction of the regulating cam, and FIGS. 8A to 8C correspond to FIGS. 6A to 6C, respectively. In FIG. 8A, the protrusion 64 is disposed so as to protrude downward. On the inner wall of each accommodating portion 65, there is a rotation restricting portion 66 that abuts against the protrusion 64 and stops the rotation of the camshaft 28 when the protrusion 64 rotates to a specified position as the camshaft 28 rotates. Provided.

  When the operating member 30 is rotated from the state of FIG. 8A and the restricting cam 63 is rotated forward in the direction of the arrow, the projecting portion 64 rotates in the direction of the arrow, and FIG. As shown in (c), the protrusion 64 comes into contact with the rotation restricting portion 66 and the rotation stops. According to this, since the operation member 30 is rotated until the rotation of the operation member 30 is stopped, the cam 29 can always be rotated to the normal position in FIG. 27 can be reliably connected, and the reliability of the connector 11 can be improved.

  As described above, the connector 11 according to the present embodiment can connect the device terminal 27 inserted into the connector housing 15 to the connector terminal 18 by rotating the operation member 30. There is no need to perform bolt fastening work. For example, the inverter-side casing is mounted on the connector 11 attached to the motor-side casing, and the motor and the inverter device terminals are connected by a simple operation of rotating the operation member 30 of the connector 11 in the forward direction. Can do. For this reason, since a work space can be ensured comparatively widely, the connection work between electrical devices can be performed efficiently, and the work man-hour can be reduced.

  Further, in the connector 11 of the present embodiment, since the head 46 of the operation member 30 is exposed in a direction intersecting (substantially orthogonal) with the axial direction of the connector housing 15, when the operation member 30 is rotated. The rotation operation can be performed using the outside of the casing, that is, the gap between the casings. Therefore, the connection work between the electrical devices can be performed more efficiently.

  Moreover, in the connector 11 of this embodiment, since the apparatus terminals of two electrical devices can be directly connected without using the wires of the wire harness as in the prior art, the distance between the electrical devices can be greatly reduced. And space saving between electrical devices can be achieved. Furthermore, when fastening the device terminal and the connector terminal 18 with bolts, conventionally, for example, a work port for inserting and removing a bolt fastening tool into and from a motor-side housing, and a waterproof for opening and closing the work port. Although it has been necessary to provide a lid having a structure, if the connector 11 of the present embodiment is used, these are not necessary, so that the housing structure can be simplified.

  Moreover, in the connector 11 of this embodiment, since the device terminal 27 inserted in the terminal accommodating part 36 is arrange | positioned away from the contact part 38 (contact 42) of the connector terminal 18, the insertion space of the equipment terminal 27 is widened. Can be secured. Thus, when the device terminal 27 is inserted into the terminal accommodating portion 36, the device terminal 27 can be inserted in a non-contact manner with the connector terminal 18, so that damage due to these contacts is prevented and the insertion load (insertion force) of the device terminal 27 is prevented. ) Can be almost unloaded.

  Further, in the connector 11 of the present embodiment, the device terminal 27 inserted into the terminal accommodating portion 36 is shaped so as to be sandwiched between the contact portion 38 (contact 42) of the connector terminal 18 and the side wall 53. Since the connection is established, the connection state between the connector terminal 18 and the device terminal 27 can be favorably maintained. In addition, the operation member 30 is connected to the connector terminal 18 and the device terminal 27 because the locking portions 59a to 59d are locked to the lock members 60a and 60b, so that the rotation in the reverse rotation direction is restricted. The state can be held more stably, and the reliability of the connector 11 can be improved.

  Further, in the connector 11 of the present embodiment, one camshaft 28 supports three cams 29, and the two connector terminals 18 located on both sides thereof are pressed by the rotation of the cams 29, respectively. It is like that. Accordingly, the six connector terminals 18 can be connected to the device terminals 27 in a lump by simply rotating the operation member 30, so that the connection work can be simplified and speeded up.

  The connector 11 of the present embodiment rotates the camshaft 28 by rotating the operation member 30 with a tool, but the structure for rotating the camshaft 28 is not limited to the example of the present embodiment. For example, a lever in which the operation member 30 is connected to the camshaft can be used. According to this, it becomes possible to rotate the camshaft 28 by tilting the lever without using a tool. Furthermore, although the cam 29 of this embodiment is supported by the camshaft 28, other configurations can be applied as long as the cam 29 is supported rotatably and can be rotated from the outside.

  The connector 11 of the present embodiment connects the connector terminal 18 and the motor-side device terminal 27 with a cam mechanism. Instead, the connector terminal 18 and the inverter-side device terminal are connected to the cam mechanism. It can also be configured to connect each of them. Further, in the present embodiment, the case where the device terminal 27 is inserted into the stationary connector housing 15 has been described. However, if the device terminal 27 is relatively inserted into the connector housing 15, the device terminal 27 and the connector housing 15 are inserted. Either of them may be stationary.

  In the connector 11 of the present embodiment, the example in which the contact portion 38 of each connector terminal 18 is connected to one device terminal has been described. However, the present invention is not limited to this, and two devices are provided in one contact portion 38. It is also possible to configure such that both the terminal, that is, both the motor-side device terminal 27 and the inverter-side device terminal are connected. In this case, the connector 11 needs to be provided with a space in which two device terminals can be inserted. Further, by providing two cam mechanisms on the connector 11 and operating the respective cam mechanisms, the inverter-side and motor-side device terminals can be connected to the contact portions 38 of the connector terminals 18 respectively.

(Second Embodiment)
Below, other embodiment for implementing this invention is described. However, each of these embodiments is basically the same as that of the first embodiment. Therefore, in the following, differences from the first embodiment will be mainly described, and components having common functions are denoted by the same reference numerals as appropriate, and description thereof will be omitted. In the following embodiments, the directions of arrows X to Z are defined in the same manner as in the above embodiments.

  The difference between the connector 67 of the present embodiment and the connector 11 of the first embodiment is that the device terminal is formed by bending in a direction different from the insertion direction into the connector housing, and the contact portion is formed along the bent surface of the device terminal. It is in the point of sliding and connecting.

  As shown in FIG. 9, the connector 67 of this embodiment is formed by assembling two connectors 68 and 69 made of resin. As shown in FIG. 10, the connector 68 includes a cylindrical frame body 70, a flange portion 16 that is connected to the base end portion of the frame body 70 and protrudes in the outer circumferential direction, and a flange housing 16. A device terminal 72 is accommodated. A packing 73 is mounted in an annular groove on the upper surface of the flange portion 71, and a flange portion 16 is integrally formed at the lower portion of the flange portion 71. The connector 68 is disposed, for example, inside a housing (not shown) that accommodates the motor. The connector 70 protrudes outward through the opening in the housing wall of the housing, and the packing 73 is pressed against the inner surface of the housing wall. Then, the bolt passed through the through hole of the flange portion 16 is screwed into the through hole of the instrument wall or the like so as to be fixed to the housing.

  On the other hand, as shown in FIG. 11, the connector 69 is a connector terminal 76 connected to an inverter-side device terminal in a connector housing formed by communicating a rectangular frame 74 and a cylindrical portion 75 in the axial direction. It is configured to accommodate. The frame 74 holds the braid 77 of the connector terminal 76, and the cylindrical portion 75 holds the camshaft 28 rotatably.

  The connector terminal 76 has a metal contact portion 78 connected to one end side of the braid 77 and an inverter-side device terminal (not shown) connected to the other end side of the braid 77. The camshaft 28 is arranged with the axial direction in the longitudinal direction (Y direction) of the tubular portion 75, and is connected to the operation member 30 through an opening 79 formed at one end portion of the tubular portion 75 in the longitudinal direction. It has become so. For example, the connector 69 protrudes the cylindrical portion 75 outward from the front wall of a housing (not shown) that accommodates the inverter, and the upper end surface of the cylindrical portion 75 is brought into contact with the device wall. The frame body 74 disposed on the inner side is fixed to the housing by being attached to the instrument wall or the like.

  The connector 67 of the present embodiment is a device on the motor side by fitting the cylindrical portion 75 of the connector 69 into the frame body 70 of the connector 68 by bringing the casing accommodating the inverter close to the casing accommodating the motor. The terminal 72 and the connector terminal 76 on the inverter side are electrically connected. The frame body 70 of the connector 68 is provided with an opening 86 (FIG. 10) that overlaps the opening 79 of the cylindrical portion 75 of the connector 69 at one end in the longitudinal direction.

  FIG. 12 is a view of the frame body 74 of the connector 69 as viewed from above. The frame body 74 is formed by raising a plurality of walls in a frame shape from the upper surface of a rectangular bottom plate. As shown in FIGS. 11 and 12, the connector terminal 76 is provided extending in the horizontal direction along the bottom plate of the frame 74 so that the braid 77 surrounds the connection portion with the contact portion 78, and adjacent braids 77. Is partitioned and accommodated by the wall of the frame 74. The contact portion 78 is formed by bending a metal plate material into, for example, a U shape, one end connected to the braid 77 is cantilevered by the frame 74, and the other end is a through hole (not shown) of the bottom plate of the frame 74. The inside of the cylindrical part 75 is drooped through. The contact portions 78 are bent in opposite directions with a space in the front-rear direction and are arranged to face each other in pairs, and are provided at three places in the left-right direction, and are arranged at a total of six places. The contact portion 78 includes a pressing portion 80 that hangs down the cylindrical portion 75 in the axial direction, and a first contact piece 81 that is connected to the pressing portion 80 and bent at a substantially right angle (L-shape). .

  FIG. 13 is a view of the cylindrical portion 75 as viewed from below. The camshaft 28 is fitted and held in a semicircular groove in a plurality of shaft support portions 88 projecting downward inside the cylindrical portion 75. A cam 29 is arranged inside each pressing portion 80 arranged in the front-rear direction. Each pressing portion 80 is in contact with the cam 29, and when pressed by the rotating cam 29, it is displaced in the front-rear direction away from each other. The first contact piece 81 is provided to be bent at a substantially right angle in a direction opposite to the pressing portion 80 facing in the front-rear direction with respect to the pressing portion 80, and in a direction away from each other in the front-rear direction as the pressing portion 80 is displaced. It is supposed to move.

  On the other hand, as shown in FIG. 10, the device terminal 72 is formed by bending a plurality of metal plate materials into predetermined shapes. Each device terminal 72 has terminal lower portions 82 extending in the vertical direction arranged in a line in the longitudinal direction of the frame body 70. The terminal upper parts 83 connected to the terminal lower parts 82 are arranged to face each other in pairs in the front-rear direction, and are arranged at three places in the left-right direction. These terminal upper parts 83 have the 2nd contact piece 84 extended on the opposite side to the terminal upper part 83 which opposes the front-back direction. The second contact piece 84 is disposed in a path along which the first contact piece 81 is moved by the rotation of the cam 29 when the cylindrical portion 75 is fitted into a predetermined position of the frame body 70. The slidable angle is formed by bending in a direction substantially perpendicular to the insertion direction of the second contact piece 84, for example.

  The second contact piece 84 has a conductive contact 85 that is in electrical contact with the first contact piece 81. The contact 85 is formed with elasticity by bulging in an arc shape from the upper surface of the second contact piece 84 on which the first contact piece 81 slides, and can be elastically deformed when contacting the first contact piece 81. It has become. In FIG. 10, the contact 85 formed in a plate shape is attached to the end surface of the second contact piece 84, but the contact 85 may be formed by directly pressing the second contact piece 84. The contact 85 may be formed on the first contact piece 81 instead of the second contact piece 84.

  14A and 14B are cross-sectional views of the connector 67 in which the connector 68 and the connector 69 are fitted as seen from the axial direction of the camshaft 28. FIGS. 14A and 14B show the state before and after the cam 29 is rotated. Represents.

  When the connector 69 is fitted to the connector 68, the tubular portion 75 of the connector 69 is inserted into the frame body 70 of the connector 68. The cylindrical part 75 is inserted along the inner peripheral surface of the frame body 70 and guided to a normal position in the frame body 70. Thereby, the positions of the connectors 68 and 69 at the time of fitting are held at appropriate positions. As shown in FIG. 14A, in the connector 68, the pressing portion 80 of the connector terminal 76 is brought into contact with the first flat surface 57 of the cam 29. The second contact piece 84 of the device terminal 72 is bent and arranged in the same direction as the first contact piece 81 of the connector terminal 76, and is arranged so as to face the first contact piece 81. A contact 85 of the second contact piece 84 is disposed on the movement path of the first contact piece 81.

  In this state, the operating member 30 is operated to rotate the cam 29 in the direction of the arrow. When the cam 29 rotates, the connector terminal 76 moves in a direction in which the contact portions 78 on both sides in contact with the cam 29 are pressed by the cam 29 and away from each other. The first contact piece 81 slides along the second contact piece 84 while pressing the contact 85, and stops moving when the pressing portion 80 contacts the second flat surface 58 of the cam 29. As a result, the first contact piece 81 is in a state of pressing the contact 85 as shown in FIG. 14B, and the device terminals 72 are electrically connected to the connector terminals 76, respectively. Such an operation is simultaneously performed between each first contact piece 81 and the corresponding second contact piece 84. In FIG. 14B, the shape (U-shape) of the contact portion 78 is shown in the same manner as in FIG. 14A in order to simplify the drawing. The pressing portion 80 pressed by the elastic member is elastically deformed around the upper bent portion, and the lower first contact piece 81 swings.

  According to the connector 67 of the present embodiment, the connector terminal 76 and the device terminal 72 can be connected by rotating the operation member 30 between the housings of the motor and the inverter. Similarly, a wide work space for connection work can be secured. Further, since the connecting operation is simplified by rotating the operation member 30, the number of work steps can be reduced. Furthermore, in the connector 67 of this embodiment, the reliability of the connector 67 is improved by applying the above-described reverse rotation prevention structure of the cam 29 (FIG. 7) and the rotation amount restricting structure of the camshaft 28 (FIG. 8). Can do.

  In the connector 67 of the present embodiment, when the second contact piece 84 of the device terminal 72 is inserted into the cylindrical portion 75, the first contact piece 81 of the connector terminal 76 is located away from the second contact piece 84. Since it is arranged, it is possible to absorb variations in the insertion position of the second contact piece 84 and dimensional variations between the first contact piece 81 and the second contact piece 84. Thereby, the damage by contact with the 1st contact piece 81 and the 2nd contact piece 84 can be prevented reliably.

  Moreover, in the connector 67 of this embodiment, since the 1st contact piece 81 slides along the 2nd contact piece 84, the oxide film formed in the surface of the 1st contact piece 81 and the 2nd contact piece 84, respectively is formed. It can be removed by friction. Thereby, the electrical connection of the 1st contact piece 81 and the 2nd contact piece 84 can be performed reliably, and the reliability of the connector 67 can be improved more.

  In the present embodiment, the first contact piece 81 and the second contact piece 84 are spaced apart from the beginning of fitting the cylindrical portion 75 to the frame 70, but the first contact piece 81 is It can also be provided at a position where it can slightly contact the contact 85 of the two-contact piece 84. Even if it does in this way, since the position shift with the 1st contact piece 81 and the 2nd contact piece 84 can be absorbed with the contact 85, the damage at the time of a contact can be prevented. In this case, the connection between the device terminal 72 and the connector terminal 76 can be turned on / off by an external circuit provided outside the connector 67.

  Further, in the present embodiment, an example in which the first contact piece 81 and the second contact piece 84 are formed by being bent in a direction substantially orthogonal to the insertion direction of the second contact piece 84, that is, in the same direction as each other, has been described. However, the bending direction of the first contact piece 81 and the second contact piece 84 is not limited to this direction. For example, if the second contact piece 84 is disposed in the movement path of the first contact piece 81 and the first contact piece 81 is slidably bent with respect to the bent second contact piece 84, The first contact piece 81 and the second contact piece 84 may be bent in different directions.

  FIG. 15 shows an example in which the first contact piece 81 and the second contact piece 84 have different bending directions. The first contact piece 81 is bent in a direction substantially orthogonal to the insertion direction of the second contact piece 84, but the second contact piece 84 is slightly in the insertion direction with respect to the bending direction of the first contact piece 81. Tilt is formed. In this case, when the cam 29 rotates, the first contact piece 81 moves while pushing down the second contact piece 84 in the direction of the arrow. With this configuration, the above-described effects can be obtained without providing the contact 85 on the second contact piece 84. As shown in FIG. 15, it is preferable that a tapered surface 87 for reducing friction at the time of contact with the second contact piece 84 is formed at the tip of the first contact piece 81.

(Third embodiment)
Next, a third embodiment of the connector according to the present invention will be described with reference to the drawings. The difference of the connector of this embodiment from the above embodiment is that the camshaft 28 is automatically rotated when the two connectors 90 and 91 constituting the connector are fitted. Hereinafter, the structure of the connectors 90 and 91 will be described focusing on differences from the above embodiment.

  FIG. 16 shows an exploded perspective view of the connector 90. The connector 90 is configured by accommodating a motor-side device terminal 92 in a connector housing including a cylindrical frame body 70, a flange portion 71 protruding in the outer peripheral direction of the frame body 70, and a flange portion 16. The device terminal 92 is formed by bending a plurality of metal plate materials into predetermined shapes. Each device terminal 92 has terminal lower portions 93 extending in the vertical direction arranged in a row in the longitudinal direction of the frame body 70, and terminal upper portions 94 connected to the terminal lower portions 93 are arranged to face each other with a space in the front-rear direction. They are arranged at three places in the left-right direction. A contact 85 bulging in an arc shape is provided on the surface of each terminal upper portion 94 facing the front-rear direction. In the present embodiment, the terminal lower portion 93 and the terminal upper portion 94 are formed so as to extend straight in the vertical direction.

  FIG. 17 shows an exploded perspective view of the connector 91. The connector 91 is configured by housing a connector terminal 97 connected to a device terminal on the inverter side in a connector housing formed by communicating a frame body 95 and a cylindrical portion 96 in the axial direction. In the connector terminal 97, the braid 77 is accommodated inside a plurality of walls 98 that rise in a frame shape from the bottom plate of the frame 95, and the contact portion 99 connected to one end of the braid 77 serves as a through hole in the bottom plate of the frame 95. The inside of the cylindrical part 96 is hung down straight.

  The tubular portion 96 accommodates a resin mounting member 100. The attachment member 100 is inserted from an opening below the tubular portion 96 and is locked to the inner wall of the tubular portion 96. The mounting member 100 includes a rectangular outer frame 101 and a plurality of shaft support portions 102 that bridge between opposing inner walls of the outer frame 101 in the short direction. In the shaft support portion 102, a groove 103 having a semicircular cross section for supporting the camshaft 28 is formed in the upper portion. The camshaft 28 is rotatably supported between a groove 103 of the camshaft support portion 102 and a groove of another shaft support portion that protrudes downward from the inside of the tubular portion 96. A cam 29 is positioned between the adjacent shaft support portions 102.

  FIG. 18 shows a cross section of the connection state between the device terminals 92 and the connector terminals 97 of the connectors 90 and 91 fitted to each other. In this embodiment, as in the other embodiments, the device terminal 92 and the connector terminal 97 are connected by the rotation of the cam 29 supported by the camshaft 28. On both sides of the cam 29 in the front-rear direction, terminal accommodating portions 104 that penetrate the attachment member 100 in the vertical direction are provided along the inner wall of the outer frame 101. In each terminal accommodating portion 104, a terminal upper portion 94 of the device terminal 92 and a contact portion 99 of the connector terminal 97 are inserted.

  The terminal accommodating portion 104 is provided with contact portions 99 of the pair of connector terminals 97 in contact with the cams 29, and a terminal upper portion 94 of the device terminal 92 is formed in a gap between each contact portion 99 and the inner wall of the outer frame 101. Inserted and positioned. The terminal upper part 94 is brought into contact (pressed) with the contact part 99 displaced by the rotation of the cam 29. In the present embodiment, the terminal upper portion 94 is sandwiched and held between the contact portion 99 and the inner wall of the outer frame 101.

  Next, the configuration of the rotation operation unit that rotates the cam 29 will be described. As shown in FIG. 17, the connector 91 has plate-like members 105 that are rotatably supported by the camshaft 28 at both ends of the camshaft 28. The plate-like member 105 is formed to have a flat surface 106 obtained by chamfering a part of a plate member having a circular cross section in the thickness direction, and is provided outside the outer frame 101 of the mounting member 100. A cam groove 107 extending in a circular arc shape from the flat surface 106 is provided on the plate surface of the plate-like member 105 opposite to the cam shaft 28. In the present embodiment, the plate-like member 105 and the cam groove 107 constitute a rotation operation unit.

  On the other hand, as shown in FIG. 19, the connector 90 has a pair of columnar members 108 that are erected from the inside of the frame body 70 and inserted into the cylindrical portion 96 of the connector 91. As shown in FIG. 20, the columnar member 108 is provided with a convex portion 109 that is opposed to the plate-like member 105 when the connectors 90 and 91 are fitted and engages with the cam groove 107. The convex portion 109 is formed to be movable along the cam groove 107 when the connectors 90 and 91 are fitted, that is, when the connectors 90 and 91 are relatively close to each other. The cam groove 107 is formed so that the linear motion of the convex portion 109 when the cams 90 and 91 are fitted can be converted into the rotational motion of the cam shaft 28.

  FIG. 19A shows one scene in the process of fitting the connectors 90 and 91 together. When the connectors 90 and 91 are relatively close to each other, the columnar member 108 of the connector 90 is inserted into the cylindrical portion 96 of the connector 91, and the convex portion 109 inserted into the cylindrical portion 96 is inserted into the cam groove 107 of the plate-like member 105. Engaged. The convex portion 109 engaged with the cam groove 107 moves along the cam groove 107 as the connectors 90 and 91 move relative to each other, and accordingly, the camshaft 28 rotates in the direction of the arrow. That is, the cam groove 107 formed in the plate-like member 105 converts the linear motion of the convex portion 109 into the rotational motion of the cam shaft 28.

  On the other hand, when the connectors 90 and 91 are relatively close to each other, the terminal upper portion 94 of the device terminal 92 is inserted into the terminal accommodating portion 104 of the attachment member 100. At this time, since the terminal accommodating portion 104 is opened with an opening width larger than the thickness of the terminal upper portion 94, the terminal upper portion 94 is prevented from coming into contact with the attachment member 100 or the contact portion 99 of the connector terminal 97. Can do. In particular, in the present embodiment, the cam groove 107 is formed to extend in a circular arc shape after extending straight from the flat surface 106, and therefore, when the convex portion 109 moves along the linear cam groove 107. The cam 29 does not rotate (the contact part 99 moves). For this reason, it can prevent that the opening width of the terminal accommodating part 104 narrows by rotation of the cam 29, and can insert the apparatus terminal 92 in the terminal accommodating part 104 non-contactingly.

  Thus, when the device terminal 92 is inserted into the terminal accommodating portion 104, the convex portion 109 starts to move in the arc-shaped cam groove 107. As a result, the cam 29 starts to rotate, and the contact portion 99 pressed against the cam 29 moves. Then, when the contact portion 99 presses the terminal upper portion 94 of the device terminal 92 and the cams 90 and 91 are fitted in the normal positions, the terminal upper portion 94 is connected to the contact portion 99 as shown in FIG. It is connected to the contact portion 99 in such a manner as to be sandwiched between the inner wall of the outer frame 101.

  As described above, in the present embodiment, the rotation operation unit that rotates the camshaft 28 is disposed inside the connectors 90 and 91, and the camshaft 28 is rotated using the force that brings the connectors 90 and 91 closer. Therefore, it is not necessary to perform the rotation operation of the camshaft 28 from the outside. As a result, it is not necessary to operate the rotation operation unit from the outside as in the above-described embodiment, and the camshaft 28 can be rotated with one action only by fitting the connectors 90, 91. The work efficiency of the connection work 91 can be increased, and the number of work steps can be reduced. In addition, since it is not necessary to expose the rotation operation unit to the outside, it is possible to save the space between the casings of each electrical device.

  In the present embodiment, since the device terminal 92 can be inserted in a non-contact manner when the device terminal 92 is inserted into the terminal accommodating portion 104, damage to the member due to contact can be prevented, and the insertion load of the device terminal 92 can be prevented. Since the (insertion force) can be almost unloaded, the work load can be reduced.

  In the present embodiment, the example in which the plate-like member 105 is provided at both ends of the camshaft 28 has been described, but it may be provided only on one side. Further, the shape of the cam groove 107 formed in the plate-like member 105 is not limited to the example of the present embodiment, and can be formed in an arc shape as a whole.

  As mentioned above, although embodiment of this invention has been explained in full detail with drawing, embodiment mentioned above is only an illustration of this invention, and this invention is not limited only to the structure of these embodiment. . Needless to say, even if there is a design change within a range not departing from the gist of the present invention, it is included in the present invention.
