[0003] Patent Document 1: Japanese Patent Application Publication No. 2003-257546 Summary of the invention Problems to be solved by the invention
[0004] However, the detection member integrally has a shift operation portion pressed by a finger and legs extending from both ends of the shift operation portion. In this shape, when the rod is in a semi-engaged state, if the detection member is pressed from above, the ends of the legs come into contact with a prescribed portion of the other party, thereby keeping the detection member in a standby position. However, if the detection member is pressed with excessive force, a force in the opening direction is applied to the legs, so there is a possibility that the detection member is forcibly displaced in the opening direction. Therefore, there is a concern that although the rod is in a semi-engaged state, the operator may mistakenly believe that the engagement position has been reached.

[0009] First, embodiments of the present invention will be described by way of examples. [1] The connector with a lever of the present invention is connected to the other connector in a manner that terminals provided on the connector housing and terminals of the other connector are completely engaged with each other when a lever rotatably provided on a connector housing that is engaged with the other connector is rotated from a pre-engaging position to an engaged position. The connector with a lever has a detection member, and the detection member is mounted on the rod in a manner that allows the detection member to move from a standby position to a detection position only when the rod is in the engaged position. The detection member has a head and a leg. In order to operate the detection member, the head is configured to be exposed from the rod, and the leg is formed to extend from the head so that the leg is inserted into an insertion recess of the connector housing when the rod is in the engaged position. A deformation suppression portion is provided between the connector housing and the leg, and when the detection member is pressed from above when the rod is in the pre-engaging position, the deformation suppression portion suppresses deformation of the leg in an opening direction.
[0010] According to this configuration, since the deformation suppression portion for suppressing deformation of the leg portion in the opening direction is provided between the connector housing and the leg portion, when the lever is in the pre-mating position, even if the detection member in the standby position is pressed from above, the position of the leg portion is maintained by the deformation suppression portion. Therefore, when the lever is in the pre-mating position, even if the detection member in the standby position is pressed from above, the detection member is difficult to move from the standby position.
[0011] [2] Furthermore, preferably, the connector with a rod has a guide portion, and when the rod is rotated, the guide portion guides the movement of the detection member by allowing the contact surface of the leg to slide on a guide surface provided on the connector housing, and the deformation suppression portion includes the contact surface formed in the shape of an inclined surface that descends in the opening direction, and the guide surface formed in the shape of an inclined surface in surface contact with the contact surface. According to this configuration, since the contact surface and the guide surface are in the shape of inclined surfaces, the deformation suppression portion can be provided in a smaller space. Furthermore, even when the deformation suppression portion is provided, the connector with a rod can be miniaturized.
[0012] [3] Furthermore, preferably, the connector with a rod has a guide portion, and when the rod is rotated, the guide portion guides the movement of the detection member by sliding the contact surface of the leg on the guide surface provided on the connector housing, the rotation axis of the rod and the movement axis of the detection member are staggered, and the guide portion is configured to guide the detection member and the rod to the mating position based on the operation force from above when the detection member is pressed from above when the rod is in the pre-mating position. According to this configuration, when the rod is in the pre-mating position, if the detection member is pressed from above, the rod can be rotated to the mating position by the guide portion by the force of pressing the detection member from above. When the rod reaches the mating position, the detection member can be directly shifted from the standby position to the detection position by the force of pressing the detection member from above. In this way, the rotation operation of the rod and the displacement operation of the detection member can be performed as a series of operations. Therefore, the operability when connecting the connector with a rod to the other connector can be improved.
[0013] [4] Furthermore, preferably, the contact surface is formed in an inclined shape along the rotation direction of the rod at the end of the leg, and the guide surface is formed in the entire area of the passage through which the leg passes and is in an arc shape. According to this configuration, since the guide surface for guiding the movement of the contact surface provided at the end of the leg is formed in a large range, the guide portion can guide the rotation operation of the rod regardless of where the rod is located before the mating position. Therefore, it can further contribute to improving the operability when connecting the connector with the rod to the other connector.
[0014] [5] Furthermore, preferably, a first deformation suppression portion and a second deformation suppression portion as the deformation suppression portion are provided between the connector housing and the leg portion, and the second deformation suppression portion suppresses deformation of the leg portion in an opening direction relative to an operation of restoring the lever from the mating position when the detection member is located at the detection position. According to this configuration, when the detection member is located at the detection position, even if the lever is rotated from the mating position to the non-mating direction, the position of the leg portion can be maintained by the second deformation suppression portion. Therefore, when the detection member is located at the detection position, even if the lever is rotated from the mating position to the non-mating direction, the detection member can be prevented from shifting from the detection position.
[0015] [6] Furthermore, the rod preferably has a covering portion that covers the deformation suppression portion from the outside. According to this configuration, the covering portion of the rod can also suppress deformation of the leg portion in the opening direction, so that the detection member can be further difficult to shift from the standby position.
[0016] [Details of Embodiments of the Invention] (First embodiment) The specific examples of the present invention are described below with reference to the accompanying drawings. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each of the drawings, for the convenience of explanation, a part of the structure is sometimes enlarged or simplified. In addition, the dimensional ratios of each part are sometimes different from the actual ones.
[0017] (Connector with rod 1) like Figure 1 As shown, the lever connector 1 includes a connector housing 3 that is mated with a mating connector 2 and a lever 4 that is rotatably mounted on the connector housing 3. The connector housing 3 includes a housing body 3a and a cover 3b that is fixed to the upper portion of the housing body 3a. When the connector housing 3 is mated with the mating connector 2, a plurality of terminals (not shown) provided inside the connector housing 3 are electrically connected to a plurality of terminals (not shown) of the mating connector 2.
[0018] When the connector 1 with a lever is connected to the mating connector 2, the lever 4 is moved from the initial position P1 ( Figure 1 state) to the mating direction ( Figure 1 The rod-connector 1 and the mating connector 2 are rotated in the direction of the arrow R1, so that the terminals of the mating connector 2 and the connector housing 3 are completely fitted with each other. One of the rod-connector 1 and the mating connector 2 is a male connector, and the other is a female connector.
[0019] (Pole 4) like Figure 1 As shown, the rod 4 has a width direction ( Figure 1 The rod base 7 is arranged in the Y-axis direction of the rod base 7, and a pair of arm portions 8 extending from both sides of the rod base 7. The arm portions 8 are rotatably mounted on the shaft portion 9, and the shaft portion 9 is provided on both sides of the connector housing 3. The rod 4 rotates around the axis of the shaft portion 9.
[0020] like Figure 2 and Figure 3 As shown, a cam mechanism 10 is provided between the mating connector 2 and the rod 4. The cam mechanism 10 generates a load for engaging the rod-attached connector 1 with the mating connector 2 when the rod 4 rotates. The cam mechanism 10 has, for example, a cam pin 11 formed on the side of the mating connector 2 (see Figure 3 ) and a cam hole 12 formed in the arm portion 8. The cam hole 12 is formed in a curved shape, for example. Figure 2 When the cam mechanism 10 rotates in the direction of the arrow R1), the cam mechanism 10 presses the circumference of the cam hole 12 downward with the cam pin 11, thereby completely fitting the rod connector 1 with the counterpart connector 2.
[0021] The rod connector 1 is in the state where the rod 4 is moved from the pre-engagement position ( Figure 2The area E1 shown in FIG. 1 is rotated to the mating position ( Figure 2 and Figure 3 The lever 4 is at the mating position P2, and the lever 4 is connected to the mating connector 2 in such a way that the terminals of the lever connector 1 and the mating connector 2 are completely mated with each other. The pre-mating position refers to, for example, the range from the initial position P1 to the front of the mating position P2 in the rotation range of the lever 4. When the lever 4 is at the mating position P2, the locking piece 13 (see FIG. 1 ) formed on the upper wall of the connector housing 3 is locked. Figure 2 ) is maintained in the position state of the fitting position P2.
[0022] (Detection component 14) like Figure 4 and Figure 5 As shown, the rod connector 1 includes a detection member 14, which detects whether the rod 4 is located at the mating position P2. The detection member 14 has a head 15 and a leg 16. In order to operate the detection member 14, the head 15 is configured to be exposed from the rod 4. That is, the head 15 can be operated by an operator from the outside with a finger or the like. The leg 16 is formed in a manner extending from the head 15. In this example, a pair of legs 16 are formed on both sides of the head 15.
[0023] like Figure 6 As shown, a pair of (at Figure 6 In the case of (only one side is shown in the figure), an opening 17 for inserting the leg 16 is formed. A support portion 18 is formed on the rod 4 to support the head 15 of the detection member 14 when being pushed in.
[0024] like Figure 4 As shown, the connector 1 with a lever has a guide portion 21, and when the lever 4 is rotated, the guide portion 21 slides on a guide surface 20 provided on the connector housing 3 through the contact surface 19 of the leg portion 16, thereby guiding the movement of the detection member 14. The guide portion 21 functions as a guide member that guides the movement of the detection member 14 when the lever 4 is rotated. The guide surface 20 is formed on the upper surface of a guide wall 22, and the guide wall 22 is formed on the side wall surface of the connector housing 3 (the cover 3b in this example).
[0025] The moving end of the leg 16 in the guide surface 20 is provided with an insertion recess 23 for inserting the leg 16. The insertion recess 23 is arranged in the width direction ( Figure 4 The insertion recess 23 is formed by recessing the side wall of the connector housing 3. When the lever 4 is located at the mating position P2, the leg 16 can be inserted into the insertion recess 23 of the connector housing 3.
[0026] like Figure 7As shown in (a), the detection member 14 is located at the standby position Pa before being pushed in. In addition, when the rod 4 is located at the pre-engagement position, the detection member 14 is restricted from moving downward by the guide wall 22 and is located at the standby position Pa. Figure 7 As shown in (b), when the rod 4 is at the fitting position P2, the detection member 14 is switched to the detection position Pb by the push-in operation because there is no guide wall 22. In this way, the detection member 14 is mounted on the rod 4 in a manner that allows it to move from the standby position Pa to the detection position Pb only when the rod 4 is at the fitting position P2.
[0027] like Figure 7 As shown in (a) and (b), the detection member 14 has a locking portion 24 for maintaining the position state of the detection member 14 when it is located at the detection position Pb. The locking portion 24 has a locking groove 25 on the wall surface of the leg portion 16. When the detection member 14 is operated to the detection position Pb, the locking portion 24 is locked by engaging the protrusion 26 formed on the rod 4 with the locking groove 25. In addition, a window portion 27 is formed at the opening of the arm portion 8 of the rod 4, and the window portion 27 is generated when the protrusion 26 is formed on the rod 4 by the sliding mold.
[0028] (Deformation suppression portion 30) like Figure 4 and Figure 6 As shown, a deformation suppression portion 30 is provided between the connector housing 3 and the leg portion 16. When the rod 4 is in the pre-engagement position and the detection member 14 is pressed from above, the deformation suppression portion 30 suppresses the leg 16 from moving in the opening direction ( Figure 6 In the case of this example, the deformation suppression portion 30 is formed in the guide portion 21. That is, the deformation suppression portion 30 includes a contact surface 19 formed in an inclined surface shape descending in the opening direction, and a guide surface 20 formed in a manner of surface contact with the contact surface 19.
[0029] The contact surface 19 of this example is formed on the end surface of the leg 16, and is formed into an inclined surface shape that descends in the opening direction. In the case of this example, the contact surface 19 is formed into an inclined surface shape by providing an inclined protrusion 31 on the surface. The guide surface 20 of this example is formed into an inclined surface shape that descends in the direction opposite to the contact surface 19. In the case of this example, the guide surface 20 is formed into an inclined surface shape by providing an inclined protrusion 32 on the surface. As described above, the deformation suppression portion 30 suppresses the deformation of the leg 16 in the opening direction by the mutually engaged inclined protrusions 31 and 32.
[0030] (Covering portion 34) like Figure 6As shown, the rod 4 has a covering portion 34 that suppresses the deformation portion 30 from the outside. In the case of this example, the covering portion 34 is composed of a part of the arm portion 8. That is, the covering portion 34 is composed of a portion of the arm portion 8 that covers the leg portion 16 in the arm portion 8 that constitutes the side wall of the rod 4. When a load in the opening direction is applied to the leg portion 16, the covering portion 34 suppresses the opening deformation of the leg portion 16 by supporting the leg portion 16 from the outside.
[0031] (Rotation Operation of Lever 4 Using Pressing Operation of Detection Member 14) like Figure 8 As shown, the rotation axis L1 of the rod 4 and the moving axis L2 of the detection member 14 are arranged in a staggered manner. In addition, in the case of this example, the so-called staggered arrangement means that the moving axis L2 does not intersect with the rotation axis L1. The moving axis L2 is a line extending along the length direction of the detection member 14, and is a straight line in the case of this example. The detection member 14 moves along the moving axis L2 between the standby position Pa and the detection position Pb.
[0032] The guide portion 21 is configured to guide the detection member 14 and the rod 4 to the mating position P2 based on the operating force from above when the detection member 14 is pressed from above in a state where the rod 4 is located in the pre-mating position. The contact surface 19 of this example is formed in an inclined shape along the rotation direction of the rod 4 at the end of the leg 16. Specifically, the contact surface 19 is formed in an arc shape when the leg 16 is viewed from the side. The guide surface 20 of this example is formed in the entire area of the passage through which the leg 16 passes, and is in an arc shape. Specifically, the guide surface 20 is formed in an arc shape that is in surface contact with the contact surface 19.
[0033] Next, the operation of the connector with lever 1 according to the present embodiment will be described. (Function of the deformation suppression portion 30) like Figure 6 As shown, even though the rod 4 is not in the mating position P2 but in the pre-mating position, the detection member 14 may be pressed in by mistake. In this case, since a deformation suppression portion 30 is provided between the connector housing 3 and the detection member 14, even if the detection member 14 is pressed in from above, the load applied to the detection member 14 is released inwardly by the engagement of the inclined protrusions 31 and 32. Therefore, it is difficult to apply a force in the opening direction to the leg portion 16 of the detection member 14. Therefore, it is difficult for the detection member 14 to accidentally fall off from the connector housing 3.
[0034] (A series of operations of the lever 4 and the detection member 14) like Fig. 9As shown in (a), it is assumed that the detection member 14 is pressed in from above when the rod 4 is in the pre-engagement position. At this time, the operating force "F1 (hollow arrow in the figure)" from above is converted into a load "F2" that moves the detection member 14 along the guide surface 20 through the shape of the guide portion 21, that is, the inclined contact surface 19 and the arc-shaped guide surface 20 in surface contact with the contact surface 19. This is because: the rotation axis L1 of the rod 4 and the movement axis L2 of the detection member 14 are staggered, and the contact surface 19 and the guide surface 20 are formed obliquely. Therefore, if the detection member 14 is pressed from above when the rod 4 is in the pre-engagement position, the rod 4 can be rotated to the engagement position P2 ( Fig. 9 (b) status).
[0035] And, if Fig. 9 (b) to Fig. 9 As shown in (c), when the rod 4 reaches the mating position P2, the detection member 14 can be directly pressed into the detection position Pb by the finger that operates the rod 4 to the mating position P2. That is, the rod 4 is moved from the pre-mating position to the mating position P2 without removing the finger from the detection member 14, and then the detection member 14 is pressed from above. Through the above series of operations, the rod 4 can be rotated and the detection member 14 can be pressed.
[0036] As described above, in the case of this example, when the rod 4 is located at the pre-mating position, by pressing the detection member 14 of the rod 4 at the pre-mating position from above, the rod 4 can be rotated to the mating position P2 and the detection member 14 can be pressed into the detection position Pb continuously. Therefore, it is not necessary to perform the operation of rotating the rod 4 to the mating position P2 and the operation of pressing the detection member 14 separately. Therefore, the assembly workability when assembling the rod-equipped connector 1 to the mating connector 2 can also be improved.
[0037] According to the configuration of the above-mentioned embodiment, the following effects can be obtained. (1-1) The lever connector 1 is connected to the mating connector 2 in such a manner that the terminals provided on the connector housing 3 and the terminals of the mating connector 2 are completely mated when the lever 4 rotatably provided on the connector housing 3 mating with the mating connector 2 is rotated from the pre-mating position to the mating position P2. The lever connector 1 includes a detection member 14, which is mounted on the lever 4 in such a manner that the detection member 14 is allowed to move from the standby position Pa to the detection position Pb only when the lever 4 is at the mating position P2. The detection member 14 includes a head 15 and a leg 16, and the head 15 is arranged to be exposed from the lever 4 in order to operate the detection member 14, and the leg 16 is formed to extend from the head 15 so as to be inserted into the insertion recess 23 of the connector housing 3 when the lever 4 is at the mating position P2. A deformation suppression portion 30 is provided between the connector housing 3 and the leg 16, and when the detection member 14 is pressed from above in the state where the lever 4 is at the pre-mating position, the deformation suppression portion 30 suppresses deformation of the leg 16 in the opening direction.
[0038] According to this configuration, since the deformation suppression portion 30 for suppressing deformation of the leg portion 16 in the opening direction is provided between the connector housing 3 and the leg portion 16, when the lever 4 is in the pre-mating position, even if the detection member 14 in the standby position Pa is pressed from above, the position of the leg portion 16 is maintained by the deformation suppression portion 30. Therefore, when the lever 4 is in the pre-mating position, even if the detection member 14 in the standby position Pa is pressed from above, it is difficult for the detection member 14 to move from the standby position Pa.
[0039] (1-2) The rod connector 1 has a guide portion 21. When the rod 4 is rotated, the guide portion 21 slides on the guide surface 20 provided on the connector housing 3 through the contact surface 19 of the leg 16, thereby guiding the movement of the detection member 14. The deformation suppression portion 30 includes a contact surface 19 formed in an inclined surface shape that descends in the opening direction, and a guide surface 20 formed in an inclined surface shape in a manner of surface contact with the contact surface 19. According to this structure, since the contact surface 19 and the guide surface 20 have an inclined surface shape, the deformation suppression portion 30 can be provided in a smaller space. Furthermore, even in the case where the deformation suppression portion 30 is provided, the rod connector 1 can be miniaturized.
[0040] (1-3) The rotation axis L1 of the rod 4 and the moving axis L2 of the detection member 14 are arranged in a staggered manner. The guide portion 21 is configured to guide the detection member 14 and the rod 4 to the mating position P2 based on the operating force from above when the detection member 14 is pressed from above when the rod 4 is in the pre-mating position. According to this configuration, when the rod 4 is in the pre-mating position, if the detection member 14 is pressed from above, the rod 4 can be rotated to the mating position P2 by the guide portion 21 by the force of pressing the detection member 14 from above. When the rod 4 reaches the mating position P2, the detection member 14 can be directly shifted from the standby position Pa to the detection position Pb by the force of pressing the detection member 14 from above. As described above, the rotation operation of the rod 4 and the displacement operation of the detection member 14 can be performed as a series of operations. Therefore, the operability when connecting the connector 1 with the rod to the counterpart connector 2 can be improved.
[0041] (1-4) The contact surface 19 is formed in an inclined shape along the rotation direction of the rod 4 at the end of the leg 16. The guide surface 20 is formed in the entire area of the passage through which the leg 16 passes, and is in an arc shape. According to this structure, since the guide surface 20 that guides the movement of the contact surface 19 provided at the end of the leg 16 is formed in a wide range, the rotation operation of the rod 4 can be guided by the guide portion 21 regardless of where the rod 4 is located before the mating position. Therefore, it further helps to improve the workability when connecting the connector 1 with the mating connector 2.
[0042] (1-5) The lever 4 has the covering portion 34 that covers the deformation suppressing portion 30 from the outside. According to this configuration, the covering portion 34 of the lever 4 also suppresses deformation of the leg portion 16 in the opening direction, so that the detection member 14 is further less likely to be displaced from the standby position Pa.
[0043] (Second embodiment) Next, the second embodiment is described. In addition, the second embodiment is an example in which the opening prevention countermeasure of the leg portion 16 of the detection member 14 described in the first embodiment is also provided at other locations. Therefore, the same reference numerals are marked on the same parts as the first embodiment and the description is omitted, and only the different parts are described in detail.
[0044] (First Deformation Suppression Section 41) like Fig.10 As shown in the figure, a first deformation suppression portion 41 is provided between the connector housing 3 and the leg portion 16 as the deformation suppression portion 30 described in the first embodiment. As described above, the first deformation suppression portion 41 is provided to suppress deformation of the leg portion 16 in the opening direction when the detection member 14 is pressed from above when the lever 4 is in the pre-mating position. In addition, the first deformation suppression portion 41 has the same structure as the deformation suppression portion 30 of the first embodiment, and therefore the description thereof is omitted.
[0045] (Second Deformation Suppression Section 42) like Fig.10 and Fig.11 As shown, a second deformation suppression portion 42 is provided between the connector housing 3 and the leg portion 16, and the second deformation suppression portion 42 suppresses the leg portion 16 from deforming in the opening direction relative to the operation of restoring the lever 4 from the mating position P2 when the detection member 14 is located at the detection position Pb. The second deformation suppression portion 42 of this example includes an inclined protrusion 43 provided on the leg portion 16 and an inclined protrusion 44 provided on the connector housing 3.
[0046] The inclined protrusion 43 of the leg 16 is formed at the end of the leg 16, that is, at the side of the portion inserted into the insertion recess 23. The inclined protrusion 43 is formed, for example, in the shape of an inclined surface that descends from the inside toward the outside. The inclined protrusion 44 of the connector housing 3 is formed on the inner wall of the insertion recess 23 of the connector housing 3, that is, at a position in the insertion recess 23 that is opposite to the inclined protrusion 43. The inclined protrusion 44 is formed, for example, in the shape of an inclined surface that descends from the outside toward the inside.
[0047] (Effects of Implementation Methods) like Fig.11 As shown, it is assumed that when the detection member 14 is located at the detection position Pb, the rod 4 at the mating position P2 is moved in the direction of the pre-mating position ( Fig.11 At this time, since the leg 16 is in strong contact with the wall surface of the insertion recess 23, a force in the opening direction (the direction of the arrow H2 in the figure) is applied to the leg 16. If the force in the opening direction is large, the leg 16 is deformed, so there is a possibility that the detection member 14 is disengaged from the insertion recess 23. Therefore, even if the detection member 14 is located at the detection position Pb, the rod 4 will rotate toward the pre-engagement position.
[0048] However, in the case of this example, since the second deformation suppression portion 42 is provided between the connector housing 3 and the detection member 14, even if an opening load is applied to the detection member 14 in the direction of the arrow H2, the load applied to the detection member 14 is released inwardly by the engagement of the inclined protrusions 43 and 44. Therefore, it is difficult to apply a force in the opening direction to the leg portion 16 of the detection member 14. Therefore, it is difficult for the detection member 14 to accidentally fall off from the connector housing 3.
[0049] (Effects of Embodiments) According to the configuration of the above-described embodiment, in addition to the effects described in the first embodiment, the following effects can be obtained.
[0050] (2-1) A first deformation suppression portion 41 as a deformation suppression portion 30 is provided between the connector housing 3 and the leg 16. A second deformation suppression portion 42 is provided between the connector housing 3 and the leg 16, and the second deformation suppression portion 42 suppresses deformation of the leg 16 in the opening direction relative to the operation of restoring the rod 4 from the mating position P2 when the detection member 14 is located at the detection position Pb. According to this configuration, when the detection member 14 is located at the detection position Pb, even if the rod 4 is rotated from the mating position P2 to the non-mating direction, the position of the leg 16 can be maintained by the second deformation suppression portion 42. Therefore, when the detection member 14 is located at the detection position Pb, even if the rod 4 is rotated from the mating position P2 to the non-mating direction, it is difficult for the detection member 14 to shift from the detection position Pb.
