In the following description, components having the same or similar functions will be denoted by the same reference numerals. Duplication of these components may be omitted. Note that the components described below do not limit the scope of the embodiments. 【0010】 (First Embodiment) <1. Lever-type connector> As shown in Figure 1, the lever-type connector 1 can be connected to the male housing 200 by mating it with another housing, for example. The lever-type connector 1 comprises, for example, a housing 2 and a lever 3. 【0011】 Housing 2 is, for example, a female housing that can be fitted into a male housing 200 in the first axial direction. The first axial direction is the axial direction of housing 2. Housing 2 is fitted into the male housing 200 through an opening 26 in the housing body 11. The electric wire 27 extends from the housing body 11 from the opposite side of the opening 26 in the first axial direction. By fitting housing 2 into the male housing 200, the terminals of housing 2 are connected to the terminals of the male housing 200. In the first embodiment, housing 2 is described as a female housing as an example, but housing 2 may also be a male housing. 【0012】 As shown in FIGS. 2 and 3, the lever 3 is arranged to straddle the housing 2. The lever 3 is rotatably attached to a pair of support bosses 15 (one support boss is shown) provided on the housing 2. The lever 3 is movable about the pair of support bosses 15 from the assembling position P1 to the initial position P2. The lever 3 is movable from the initial position P2 to a fitting position (not shown) and is movable from the fitting position to the initial position P2. Here, the movement of the lever 3 from the initial position P2 to the assembling position P1 is restricted. 【0013】 The assembling position P1 is the position where the lever 3 is assembled to the housing 2. The initial position P2 is the position of the lever 3 in the state before the housing 2 is fitted into the male housing 200 (the position before the start of fitting into the male housing 200). The fitting position is the position of the lever 3 in the state after the housing 2 is fitted into the male housing 200 (the position after the completion of fitting into the male housing 200). 【0014】 In the present disclosure, the X direction, +X direction, -X direction, Y direction, +Y direction, -Y direction, Z direction, +Z direction, and -Z direction are defined as follows. 【0015】 The X direction is a direction orthogonal to the first axial direction of the housing 2 and along the second axial direction of the pair of support bosses 15. The +X direction is the left direction among the X directions when viewed from the opening 26 of the housing body 11. The -X direction is the right direction among the X directions when viewed from the opening 26. Hereinafter, when the +X direction and the -X direction are not distinguished, it is simply referred to as the "X direction". 【0016】 The Y direction is the first axial direction of the housing 2. The +Y direction is the direction of the opening 26 of the housing body 11 among the Y directions. The -Y direction is the direction opposite to the opening 26 among the Y directions. Hereinafter, when the +Y direction and the -Y direction are not distinguished, it is simply referred to as the "Y direction". 【0017】 The Z direction is the direction that intersects the X and Y directions. The +Z direction is the direction on which the connecting portion 42 of lever 3 is located. The -Z direction is the direction on the opposite side from where the connecting portion 42 of lever 3 is located. Hereafter, when the +Z direction and the -Z direction are not distinguished, they will simply be referred to as the "Z direction". 【0018】 In the following, the +X direction may be referred to as "left," the -X direction as "right," the +Y direction as "front," and the -Y direction as "rear." The +Z direction may also be referred to as "up," and the -Z direction as "down." Furthermore, the first axial direction of the housing 2 may simply be referred to as the "first axial direction." However, these expressions are for explanatory convenience only and do not limit the mounting orientation of the lever-type connector 1. 【0019】 <2. Housing Configuration> This section describes the detailed configuration of Housing 2. As shown in Figures 1 to 5, the housing 2 comprises, for example, a housing body 11, a pair of locking arms 12, a pair of restraining walls 13, a pair of stoppers 14, and a pair of support bosses 15. The pair of locking arms 12, the pair of restraining walls 13, the pair of stoppers 14, and the pair of support bosses 15 are each symmetrical members. Hereinafter, the right-side members of the pair of locking arms 12, the pair of restraining walls 13, the pair of stoppers 14, and the pair of support bosses 15 will be described, and the description of the left-side members will be omitted. Also, the right-side locking arm 12, the right-side restraining wall 13, the right-side stopper 14, and the right-side support boss 15 will be abbreviated as "locking arm 12," "restraining wall 13," "stopper 14," and "support boss 15" in the description. 【0020】 The housing body 11 has a pair of side walls 21, a top portion 22, a bottom portion 23, and a flange portion 24. The pair of side walls 21 are spaced apart in the left-right direction. The top portion 22 connects the upper edges of the pair of side walls 21. The bottom portion 23 connects the lower edges of the pair of side walls 21. The housing body 11 is formed in a substantially rectangular frame cross-section by the pair of side walls 21, the top portion 22, and the bottom portion 23. The housing body 11 has an opening 26 (see Figure 1) at its front end portion 11a. The opening 26 of the housing body 11 can be fitted into the male housing 200 (see Figure 1). 【0021】 The housing body 11 has a flange portion 24 at its front end 11a. The flange portion 24 protrudes from 11a of the housing body 11 toward the outside of the housing body 11. Here, the pair of side walls 21 are symmetrical members. Hereafter, the description of the pair of side walls 21 will focus on the right side wall 21, and the description of the left side wall 21 will be omitted. The right side wall 21 will also be abbreviated as "side wall 21" in the description. 【0022】 As shown in Figures 5 and 6, the locking arm 12 is provided on the flange portion 24. The locking arm 12 is positioned at a distance from the intersection 25 between the side wall 21 and the top portion 22, and is located outside the housing body 11. The locking arm 12 has an arm body 31, a locking portion 32, and an inclined surface 33. The arm body 31 extends, for example, backward from the back surface of the flange portion 24 along the intersection 25. The arm body 31 is an elastically deformable member corresponding to the restricting portion 51 (specifically, the first edge portion 52a), which will be described later. The arm body 31 is elastically deformable with its base end portion 31a as a fulcrum. The arm body 31 has, for example, an outer surface 31b, an inner surface 31c, an upper surface 31d, and a lower surface 31e. The arm body 31 is formed in a rectangular cross-section by, for example, an outer surface 31b, an inner surface 31c, an upper surface 31d, and a lower surface 31e. 【0023】 The locking portion 32 is integrally provided, for example, at the tip of the arm body 31. The locking portion 32 protrudes from the inner surface 31c toward the intersection 25 at the tip of the arm body 31. The locking portion 32 protrudes toward the regulating portion 51, which will be described later. The upper surface 32a of the locking portion 32 is formed flush with, for example, the upper surface 31d of the arm body 31. The lower surface 32b of the locking portion 32 is formed flush with, for example, the lower surface 31e of the arm body 31. The inclined surface 33 is provided at the tip of the locking portion 32. In a plan view, the inclined surface 33 tapers towards the leading edge 31f of the arm body 31, extending the locking portion 32 towards the leading edge 31f. The inclination angle of the inclined surface 33 is adjustable as needed. 【0024】 As shown in Figures 4, 5, and 7, the restraining wall 13 is provided on the flange portion 24. The restraining wall 13 protrudes rearward from the back surface of the flange portion 24 along the side wall 21. The restraining wall 13 is, for example, a flat plate-like portion. The restraining wall 13 is positioned at a distance from the side wall 21 to the outside of the housing body 11. The restraining wall 13 is positioned at a distance below the locking arm 12. That is, the housing 2 has, for example, a first slit (first groove) 17 between the restraining wall 13 and the locking arm 12. The base end portion 13a of the restraining wall 13 is continuously positioned on the base end portion 31a of the arm body 31 via the flange portion 24. 【0025】 The deterrent wall 13 is located on the opposite side of the side wall 21 from the regulating section 51 (described later) when the lever 3 is in its initial position P2 (see Figure 3). The deterrent wall 13 is positioned so as to overlap the regulating section 51 (specifically, the first regulating section 52) in the left-right direction. 【0026】 As shown in Figures 4 and 5, the stopper 14 is provided, for example, on the flange portion 24 and the intersection portion 25. The stopper 14 extends, for example, from the back surface of the flange portion 24 along the arm body 31. The stopper 14 is positioned at a distance from the intersection portion 25 to the outside of the housing body 11. In the vertical direction, the stopper 14 is positioned on the opposite side of the restraining wall 13 from the locking arm 12. The stopper 14 is positioned at a distance above the locking arm 12. That is, the housing 2 has, for example, a second slit (second groove) 18 between the restraining wall 13 and the locking arm 12. Here, the bottom portion 18a of the second slit 18 is located rearward in the first axial direction relative to the bottom portion 17a of the first slit 17. 【0027】 In the first embodiment, an example is described in which the bottom 18a of the second slit 18 is located rearward relative to the bottom 17a of the first slit 17, but the embodiment is not limited to this. As another example, the first slit 17 and the second slit 18 may be formed symmetrically in the vertical direction with respect to the locking arm 12. 【0028】 As shown in Figures 2 to 4, the support boss 15 is located at the vertical center of the rear end 21a of the side wall 21. The support boss 15 protrudes outward from the center of the rear end 21a in the vertical direction. The support boss 15 rotatably supports the lever 3. 【0029】 <3. Lever Configuration> Let's describe the detailed configuration of lever 3. As shown in Figures 1 and 4, the lever 3 has, for example, a pair of legs 41 and a connecting portion 42. The pair of legs 41 are arranged on the left and right sides of the housing body 11. The upper ends of the pair of legs 41 are connected by the connecting portion 42. The lever 3 has a roughly U-shape due to the connection of the upper ends of the pair of legs 41 by the connecting portion 42. The pair of legs 41 are arranged to sandwich the housing body 11 from the left and right sides. The connecting portion 42 is, for example, the part to which the operating force is applied when operating the lever 3. 【0030】 The pair of legs 41 have support holes 44 (the right support hole 44 is shown in the figure). The support holes 44 are located at the rear 41a of the leg 41. The support holes 44 are assembled by fitting into the support boss 15. The lever 3 is rotatably supported on the support boss 15 (i.e., the housing body 11) by the assembly of the support holes 44 into the support boss 15. The lever 3 can be moved around the support boss 15 as an axis to the assembly position P1 (see Figure 2), the initial position P2 (see Figure 3), and the fitted position, for example by applying an operating force to the connecting portion 42. The pair of legs 41 are symmetrical members. Hereinafter, the description of the pair of legs 41 will focus on the right leg 41, and the description of the left leg 41 will be omitted. The right leg 41 will also be abbreviated as "leg 41" in the description. 【0031】 As shown in Figures 2 to 4, the leg portion 41 is equipped with a restricting portion 51. The restricting portion 51 is located at the front portion 41b of the leg portion 41. The support hole 44 is located at the rear portion 41a of the leg portion 41. That is, the restricting portion 51 is located on the opposite side of the support hole 44. The support hole 44 is fitted into the support boss 15. With this configuration, the restricting portion 51 is located on the opposite side of the support hole 44 and the support boss 15. 【0032】 The surface 51a of the restricting portion 51 is a flat surface having a stepped recess on the housing body 11 side relative to the surface 41d of the main portion 41c of the leg portion 41. The restricting portion 51 can be inserted into the space between the restraining wall 13 and the side wall 21 (see also Figure 7). The restricting portion 51 can be inserted into the space between the locking arm 12 and the intersection portion 25 (see also Figure 6). The restricting portion 51 can be inserted into the space between the stopper 14 and the intersection portion 25. 【0033】 The restricting section 51 includes a first restricting section 52 and a second restricting section 53. The first restricting section 52 and the second restricting section 53 are arranged in a continuous manner. The first restricting section 52 includes, for example, a first edge (edge) 52a and a second edge (edge) 52b. The first edge 52a is arranged with a backward slope towards the upward direction when the lever 3 is positioned at the assembly position P1 (see Figure 4). The first edge 52a contacts the inclined surface 33 of the locking arm 12 when the lever 3 is positioned at the assembly position P1 (see Figure 6). In other words, the inclined surface 33 can contact the first edge 52a when the lever 3 is positioned at the assembly position P1. 【0034】 As shown in Figures 3, 8, and 9, the second edge 52b is positioned horizontally along the first axial direction of the housing 2, for example, when the lever 3 is in its initial position P2. The second edge 52b contacts the lower surface 32b of the locking portion 32 on the locking arm 12, for example, when the lever 3 is in its initial position P2. In other words, the locking portion 32 can contact the second edge 52b when the lever 3 is in its initial position P2. By contacting the lower surface 32b of the locking portion 32, the second edge 52b can restrict movement from the initial position P2 to the assembly position P1. 【0035】 As shown in Figures 2 to 4, the first edge 52a can contact the inclined surface 33 of the locking arm 12. The inclined surface 33 is a surface formed on the locking portion 32. The second edge 52b contacts the lower surface 32b of the locking portion 32. The locking portion 32 is located on the opposite side of the support boss 15 and the support hole 44. With this configuration, a relatively large distance L1 can be secured from the support boss 15 to the inclined surface 33 and the locking portion 32. Here, the distance L2 from the support boss 15 to the connecting portion 42 is secured to be approximately as large as distance L1. The connecting portion 42 is, for example, the part to which operating force is applied when moving the lever 3. Distances L1 and L2 will be explained in detail later. 【0036】 <4. Assembly procedure for lever-type connectors> A typical example of assembling the lever-type connector 1 will be explained based on Figures 1 to 4 and Figures 6 to 8. Note that the assembly procedure can be selected arbitrarily. As shown in Figure 4, first, with the lever 3 positioned at assembly position P1, the support hole 44 of the lever 3 is fitted into the support boss 15 of the housing 2. 【0037】 As shown in Figures 2, 6, and 7, with the support hole 44 fitted into the support boss 15, the first restricting portion 52 is inserted into the space between the restraining wall 13 and the side wall 21. The first restricting portion 52 is inserted into the space between the locking arm 12 and the intersection 25. The first restricting portion 52 is inserted into the space between the stopper 14 and the intersection 25. Furthermore, the first edge 52a of the first restricting portion 52 abuts against the inclined surface 33 of the locking arm 12. In this state, the lever 3 is assembled to the assembly position P1 of the housing 2. 【0038】 As shown in Figures 2 and 6, after the lever 3 is assembled to the assembly position P1, an operating force is applied to the connecting portion 42 of the lever 3 to move the lever 3 toward the initial position P2. Here, the first edge 52a of the first restricting portion 52 is in contact with the inclined surface 33 of the locking arm 12. With this configuration, as the lever 3 is moved toward the initial position P2, the arm body 31 of the locking arm 12 elastically deforms toward the right outer side of the housing body 11 in accordance with the first edge 52a. 【0039】 As the arm body 31 undergoes elastic deformation, the inclined surface 33 moves along the first edge 52a. As the inclined surface 33 moves along the first edge 52a, the locking portion 32 rides up onto the first restricting portion 52 from the first edge 52a. As the locking portion 32 rides up onto the first restricting portion 52, the lever 3 can be moved from the assembly position P1 towards the initial position P2. 【0040】 As shown in Figures 3, 8, and 9, when the lever 3 moves to its initial position P2, the locking portion 32 moves above the first restricting portion 52 and disengages from it. When the locking portion 32 disengages from the first restricting portion 52, the arm body 31 returns to its elastically deformed state. As the arm body 31 returns to its original state, the lower surface 32b of the locking portion 32 comes into contact with the second edge 52b of the first restricting portion 52. In this state, the lever 3 is assembled to its initial position P2, and the assembly procedure for the lever-type connector 1 is completed. 【0041】 As shown in Figures 1 and 3, when connecting a lever-type connector 1, in which the lever 3 is assembled to the housing 2, to a male housing 200, the opening 26 of the housing 2 is fitted into the male housing 200. By fitting the opening 26 of the housing 2 into the male housing 200, the terminals of the housing 2 (not shown) are connected to the terminals of the male housing 200 (not shown). With the housing 2 fitted into the male housing 200, the lever 3 is moved from the initial position P2 to the fitted position. By moving the lever 3 to the fitted position, the procedure for connecting the lever-type connector 1 to the male housing 200 is completed. 【0042】 <5. Preventing lever 3 from detaching> Next, an example of preventing lever 3 from moving from its initial position P2 to its assembly position P1 due to erroneous operation will be explained based on Figures 3, 8 to 10. As shown in Figures 3, 8, and 9, if the lever 3 attempts to move from the initial position P2 to the assembly position P1 due to erroneous operation, the second edge 52b of the first restricting portion 52 abuts against the lower surface 32b of the locking portion 32. By the second edge 52b abutting against the lower surface 32b of the locking portion 32, the lever 3 is prevented from returning from the initial position P2 to the assembly position P1 due to erroneous operation. By preventing the lever 3 from returning to the assembly position P1, the lever 3 is prevented from detaching from the housing 2 at the assembly position P1. 【0043】 Here, if the lever 3 attempts to move from the initial position P2 to the assembly position P1 due to erroneous operation, the arm body 31 will have its second edge 52b come into contact with the lower surface 32b of the locking portion 32. When the second edge 52b comes into contact with the lower surface 32b of the locking portion 32, it is conceivable that the arm body 31 will elastically deform upward. Therefore, the stopper 14 is positioned above the locking arm 12 at a distance. 【0044】 As shown in Figure 10, the arm body 31 can come into contact with the stopper 14 when it elastically deforms upward. The stopper 14 can suppress the elastic deformation of the locking arm 12. With this configuration, the lever 3 can be prevented from returning to the assembly position P1. In other words, the lever 3 can be prevented from detaching from the housing 2 at the assembly position P1. 【0045】 <6. Mechanism and Effects> According to the lever-type connector 1 of the first embodiment, as shown in Figures 2 and 6, the lever 3 is provided with a restricting portion 51. The housing 2 has an elastically deformable locking arm 12. The locking arm 12 has a locking portion 32 that protrudes toward the restricting portion 51. The locking arm 12 has an inclined surface 33 that tapers toward the locking portion 32. The restricting portion 51 of the lever 3 can be assembled to the housing 2 at the assembly position P1. In addition, the inclined surface 33 of the locking portion 32 can abut against the first edge 52a of the first restricting portion 52 when the lever 3 is positioned at the assembly position P1. 【0046】 As the lever 3 moves from the assembly position P1 to the initial position P2, the arm body 31 elastically deforms in accordance with the first edge 52a. The inclined surface 33 moves along the first edge 52a as the arm body 31 elastically deforms to the right outer side of the housing body 11 and rides onto the first restricting portion 52. The locking portion 32 is movable along the first restricting portion 52 as the inclined surface 33 rides onto the first restricting portion 52. The lever 3 is movable from the assembly position P1 to the initial position P2 as the locking portion 32 moves along the first restricting portion 52. With this configuration, the lever 3 can be assembled to the housing 2 at the assembly position P1, excluding the movable range between the initial position P2 (see Figure 3) and the fitting position. 【0047】 As shown in Figures 3 and 8, the lower surface 32b of the locking portion 32 can abut against the second edge 52b of the first restricting portion 52 when the lever 3 is in its initial position P2. The movement of the lever 3 from the initial position P2 to the assembly position P1 (see Figure 2) is restricted by the second edge 52b and the lower surface 32b of the locking portion 32 as the lower surface 32b of the locking portion 32 abuts against the second edge 52b. In other words, the lever 3 is held in the initial position P2. This configuration improves the retention of the lever 3 in relation to the housing 2. Therefore, for example, when fitting the housing 2 into the male housing 200 (see Figure 1), the lever 3 is less likely to come off the housing 2. 【0048】 Furthermore, as shown in Figures 3, 8, and 9, the housing 2 is provided with a restraining wall 13 that is continuous with the locking arm 12. The restraining wall 13 is positioned near the lower side of the locking arm 12 in the vertical direction. When the lever 3 is in the initial position P2, the restraining wall 13 is positioned so as to overlap the first restricting portion 52 from the opposite side of the side wall 21 of the housing body 11. With this configuration, when an operating force is applied to the connecting portion 42 of the lever 3 to return it from the initial position P2 to the assembly position P1 (see Figure 2), the restraining wall 13 can suppress deformation of the first restricting portion 52 toward the opposite side of the side wall 21. Therefore, the lower surface 32b of the locking portion 32 can stably contact the second edge 52b of the first restricting portion 52. 【0049】 Furthermore, as shown in Figures 3 and 8, when an operating force is applied to the lever 3 to return the arm body 31 of the locking arm 12 from its initial position P2 to the assembled position P1 (see Figure 2), the lower surface 32b of the locking portion 32 is pressed upward by the second edge 52b of the first restricting portion 52. It is conceivable that the arm body 31 will undergo elastic deformation due to the pressure of the lower surface 32b on the second edge 52b. The lever 3 may return to the assembled position P1 due to the elastic deformation of the arm body 31. 【0050】 Therefore, as shown in Figure 10, the housing 2 is equipped with a stopper 14. The stopper 14 is positioned on the opposite side of the restraining wall 13 from the locking arm 12. With this configuration, the stopper 14 can suppress upward elastic deformation of the arm body 31 when an operating force is applied to the lever 3 to return it from the initial position P2 to the assembled position P1. Thus, the arm body 31 can hold the lever 3 in the initial position P2 without increasing its strength. 【0051】 As shown in Figures 2 and 6, the arm body 31 does not need to be highly strong, so it can be appropriately elastically deformed. With this configuration, the arm body 31 can be appropriately elastically deformed while keeping the operating force applied to the connecting portion 42 of the lever 3 small. As the arm body 31 is appropriately elastically deformed, the inclined surface 33 can be moved along the second edge 52b of the first restricting portion 52. As the inclined surface 33 moves along the second edge 52b, the locking portion 32 can ride up onto the restricting portion 51. Therefore, the lever 3 can be appropriately moved from the assembly position P1 to the initial position P2. In addition, the operating force applied to the connecting portion 42 of the lever 3 can be adjusted by changing the inclination angle of the inclined surface 33. 【0052】 As shown in Figures 2 and 3, the lever 3 has a support hole 44. The support hole 44 is located on the opposite side of the first restricting portion 52. The housing 2 has a support boss 15. The support boss 15 rotatably supports the lever 3 when the support hole 44 is assembled to it. With this configuration, the first restricting portion 52 can be positioned relatively far away from the support boss 15 of the housing 2. The first edge 52a of the first restricting portion 52 can abut against the inclined surface 33 of the locking arm 12. The second edge 52b of the first restricting portion 52 can abut against the lower surface 32b of the locking portion 32 on the locking arm 12. 【0053】 In other words, the distance L1 from the support boss 15 to the inclined surface 33 and the locking portion 32 is relatively large. Therefore, the lever 3 can appropriately suppress the pressing force transmitted from the first edge 52a to the inclined surface 33 in terms of the "lever ratio" between the distance L1 and the distance L2 from the support boss 15 to the connecting portion 42 of the lever 3. The pressing force transmitted from the second edge 52b to the lower surface 32b of the locking portion 32 can also be appropriately suppressed. With this configuration, for example, it is possible to appropriately prevent the lever 3 from being erroneously operated from the initial position P2 to the assembled position P1 without unnecessarily increasing the strength of the arm body 31 (i.e., the locking arm 12). 【0054】 (Second Embodiment) Next, a second embodiment will be described with reference to Figure 11. In the second embodiment, the same or similar components as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions are omitted. As shown in Figure 11, the lever-type connector 100 is modified in which the locking arm 12 of the first embodiment is replaced with a locking arm 102. The other components of the lever-type connector 100 are the same as those of the lever-type connector 1 of the first embodiment. The locking arm 102 has a protruding portion 104. The other components of the locking arm 102 are the same as those of the locking arm 12 of the first embodiment. 【0055】 The protruding portion 104 is integrally provided on the upper surface 31d at the tip of the arm body 31. The protruding portion 104 protrudes from the upper surface 31d toward the stopper 14. The upper surface of the protruding portion 104 is positioned at a distance from the stopper 14. The upper surface 104a of the protruding portion 104 is formed flat along the lower surface 14a of the stopper 14. 【0056】 According to the lever-type connector 100 of the second embodiment, when an operating force is applied to the connecting portion 42 (see Figure 3) of the lever 3 to return the protruding portion 104 from its initial position P2 to the assembled position P1 (see Figure 2), the second edge 52b of the first restricting portion 52 presses against the lower surface 32b of the locking portion 32. It is conceivable that the arm body 31 will elastically deform upward as the second edge 52b presses against the lower surface 32b of the locking portion 32. When the arm body 31 elastically deforms upward, the upper surface 104a of the protruding portion 104 comes into contact with the lower surface 14a of the stopper 14. 【0057】 With this configuration, the protrusion 104 can adjust the amount of elastic deformation of the arm body 31. Therefore, the protrusion 104 can improve the ability of the lever 3 to be held in its initial position P2. Furthermore, the protrusion 104 can suppress variations in the position of the lever 3 at the initial position P2. 【0058】 Furthermore, the lever-type connector 100 of the second embodiment provides the same operation and effects as the lever-type connector 1 of the first embodiment. 【0059】 Several embodiments and modifications have been described above. However, the embodiments and modifications are not limited to the examples described above. For example, multiple embodiments may be implemented in combination with each other.
