Description

Technical Field

[0001] This disclosure relates to a connector.

Background Art

[0002] Conventionally, as a connector, there is one including a connector housing having a cylindrical connector body portion and a connector flange portion protruding radially outward from the outer periphery of the connector body portion, and a packing attached to the connector housing (see, for example, Patent Document 1). This packing has a cylindrical portion that covers the outer peripheral surface of the connector body portion and is disposed between the connector body portion and a mounting hole of a mounting target, and an annular flange portion that covers the end surface of the connector flange portion and is disposed between the connector flange portion and the mounting target. The flange portion has a lip portion that presses against the mounting target in a state where the connector housing is fixed to the mounting target by protruding toward the mounting target. In this configuration, the waterproofness of the relevant portion is enhanced by the lip portion pressing against the mounting target locally. Further, since the flange portion having the lip portion is connected to the cylindrical portion that covers the outer peripheral surface of the connector body portion, the radial position of the lip portion is stabilized. Therefore, the waterproofness can be highly and stably maintained.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the flange portion of the packing of the connector as described above, since the surface facing the end surface of the connector flange portion has a shape along the end surface of the connector flange portion, the force pressing against the end surface of the connector flange portion is dispersed without being concentrated. As a result, the waterproofness between the flange portion and the connector flange portion may be inferior to the waterproofness between the lip portion and the mounting target.

[0005] The purpose of this disclosure is to provide a connector that can improve waterproofness. [Means for solving the problem]

[0006] The connector of the present disclosure comprises a connector housing fixed to a mounting object, having a cylindrical connector body portion that can be fitted into a mounting hole of the mounting object along a first direction and a connector flange portion that protrudes radially outward from the outer circumference of the connector body portion; and a packing having a cylindrical portion that covers the outer surface of the connector body portion and is disposed between it and the mounting hole, and an annular flange portion that covers the end face of the connector flange portion in the first direction and is disposed between it and the mounting object, wherein the flange portion has a first lip portion that protrudes in the first direction and presses into contact with the mounting object when the connector housing is fixed to the mounting object, and a second lip portion that protrudes in a first opposite direction which is the opposite direction to the first direction and presses into contact with the connector flange portion when the connector housing is fixed to the mounting object. [Effects of the Invention]

[0007] According to this disclosed connector, waterproofing can be improved. [Brief explanation of the drawing]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The connector disclosed herein is [1] A connector comprising: a connector housing fixed to a mounting object, having a cylindrical connector body portion that can be fitted into a mounting hole of the mounting object along a first direction and a connector flange portion that protrudes radially outward from the outer circumference of the connector body portion; and a packing having a cylindrical portion that covers the outer surface of the connector body portion and is disposed between it and the mounting hole, and an annular flange portion that covers the end face of the connector flange portion in the first direction and is disposed between it and the mounting object, wherein the flange portion has a first lip portion that protrudes in the first direction and presses into contact with the mounting object when the connector housing is fixed to the mounting object, and a second lip portion that protrudes in a first opposite direction which is the opposite direction to the first direction and presses into contact with the connector flange portion when the connector housing is fixed to the mounting object.

[0010] According to this configuration, the flange portion of the packing has a first lip portion that protrudes in a first direction and makes pressing contact with the mounting object when the connector housing is fixed to the mounting object, thereby increasing the waterproofness of that area through localized pressing contact. Furthermore, the flange portion of the packing has a second lip portion that protrudes in the opposite direction to the first lip portion and makes pressing contact with the connector flange portion when the connector housing is fixed to the mounting object, thereby increasing the waterproofness of that area through localized pressing contact. Thus, it is possible to prevent liquid from passing through the outside and inside of the packing.

[0011] [2] In the above [1], the first lip portion and the second lip portion may be formed on the outer edge of the flange portion and consist of an arc-shaped portion whose cross-sectional shape cut along the radial direction exceeds 180°.

[0012] According to this configuration, the first lip portion and the second lip portion are formed on the outer edge of the flange portion and are composed of arc-shaped portions with a cross-sectional shape exceeding 180° in the radial direction, so that the pressing contact force can be kept constant in the circumferential direction of the packing. For example, if the cross-sectional shape of the first lip portion is rectangular, the first lip portion may tilt inward in the radial direction in one part of the circumferential direction of the packing, or tilt outward in other parts, so that the pressing contact force may vary in the circumferential direction, but this can be avoided. In other words, since the first lip portion and the second lip portion are composed of arc-shaped portions with a cross-sectional shape exceeding 180°, they do not deform by tilting as in the case of a rectangular shape, so that the pressing contact force can be kept constant in the circumferential direction of the packing. Therefore, the waterproof performance can be improved.

[0013] [3] In the above [1] or [2], the cylindrical portion and the flange portion may be connected by an inclined wall thickness portion, the outer diameter and wall thickness increasing as it moves in the first opposite direction.

[0014] In this configuration, the cylindrical portion and the flange portion are connected by a sloping wall thickness portion, where the outer diameter increases and the wall thickness increases as you move in the first opposite direction. As a result, the rigidity of the packing is increased at the sloping wall thickness portion. Therefore, for example, the assembly of the packing into the connector housing is improved compared to a case where the rigidity of the connection portion between the cylindrical portion and the flange portion is low. Also, for example, because the rigidity of the sloping wall thickness portion connecting the cylindrical portion and the flange portion is high, the radial positions of the first lip portion and the second lip portion of the flange portion are stabilized. For example, the radial outward movement of the first lip portion and the second lip portion is suppressed. Therefore, the waterproof performance can be made higher and more stable.

[0015] [4] In any one of the above [1] to [3], the flange portion may have a first recess formed on the radially inner side of the first lip portion and configured not to contact the mounting target in a state where the first lip portion is pressed against the mounting target, and a second recess formed on the radially inner side of the second lip portion and configured not to contact the connector flange portion in a state where the second lip portion is pressed against the connector flange portion.

[0016] According to this configuration, since the flange portion has the first recess formed on the radially inner side of the first lip portion and configured not to contact the mounting target in a state where the first lip portion is pressed against the mounting target, the force with which the first lip portion presses can be maintained at a high level. That is, for example, in a configuration where the first recess is not formed and the radially inner side of the first lip portion contacts the mounting target in a state where the first lip portion is pressed against the mounting target, there is a risk that the pressing force is dispersed, but this can be avoided. Also, since the flange portion has the second recess formed on the radially inner side of the second lip portion and configured not to contact the connector flange portion in a state where the second lip portion is pressed against the connector flange portion, the force with which the second lip portion presses can be maintained at a high level. That is, for example, in a configuration where the second recess is not formed and the radially inner side of the second lip portion contacts the connector flange portion in a state where the second lip portion is pressed against the connector flange portion, there is a risk that the pressing force is dispersed, but this can be avoided. From these facts, the waterproofness can be made higher.

[0017] [5] In any one of the above [1] to [4], the connector housing may have a fixing portion that protrudes radially outward from the outer periphery of the connector flange portion and has one fixing hole, and may be fixed to the mounting target by a bolt passing through the fixing hole.

[0018] According to the same configuration, the connector housing has a fixing portion that projects radially outward from the outer periphery of the connector flange portion and has one fixing hole, and is fixed to the mounting target by a bolt passing through the fixing hole. Therefore, the effect of enhancing waterproofness is great.\ That is, in the configuration where the connector housing is fixed to the mounting target by a bolt at one location of one fixing hole, the entire connector housing is likely to be fixed in a tilted state with respect to the mounting target.\ In this case, the waterproofness by the packing is likely to decrease, but the waterproofness can be enhanced by the first lip portion and the second lip portion. For example, the waterproofness can be guaranteed.

[0019] [Details of Embodiments of the Present Disclosure] Specific examples of the connector of the present disclosure will be described below with reference to the drawings.\ In each drawing, for convenience of explanation, a part of the configuration may be shown exaggeratedly or simplified.\ Also, the dimensional ratios of each part may be different in each drawing.

[0020] As used herein, the term "tubular" includes not only structures with a continuous circumferential wall along their entire circumference, but also structures formed by combining multiple parts, and structures with notches or other cutouts in the circumferential direction, such as a C-shape. The outer circumferential shape of a "tubular" includes, but is not limited to, circular, elliptical, and polygonal shapes with pointed or rounded corners. A "tubular" is a shape having a through hole in a plan view, and includes those where the outer circumferential shape and the inner circumferential shape of the through hole are the same, or where the outer circumferential shape and the inner circumferential shape of the through hole are different. A "tubular" includes structures having a predetermined length extending along the axial direction from which a central axis passing through the center of the through hole extends, regardless of the magnitude of that length. Furthermore, as used herein, the term "annular" may refer to any structure that forms a loop, or a continuous shape without ends, as well as a generally loop-shaped structure with a gap, such as a C-shape. The shape of an "annular" includes, but is not limited to, circular, elliptical, and polygonal shapes with pointed or rounded corners. Furthermore, terms such as "first," "second," and "third" used herein are used solely to distinguish between subjects and do not rank them. The present invention is not limited to these examples and is shown in the claims, and all modifications within the meaning and scope equivalent to the claims are intended.

[0021] (Configuration of connector 10) As shown in Figures 1 and 2, the connector 10 comprises a connector housing 20, a plurality of terminals 30, a collar 40, and a packing 50. In each figure, a first axis X, a second axis Y perpendicular to the first axis X, and a third axis Z perpendicular to both the first axis X and the second axis Y are shown. In the figures, a first direction X1, which is one direction along the first axis X, and a first opposite direction X2, which is the opposite direction to the first direction X1 are also shown. In the figures, an upward direction Z1, which is one direction along the third axis Z, and a downward direction Z2, which is the opposite direction to the upward direction Z1 are also shown.

[0022] As shown in Figures 3 and 4, the connector 10 of this embodiment is attached by bolts 70 to a metal panel 60, which is the mounting target for in-vehicle equipment installed in a vehicle. The panel 60 has a mounting hole 61 that penetrates along the first axis X and a bolt hole 62 that penetrates along the first axis X.

[0023] (Configuration of connector housing 20) The connector housing 20 is made of resin. As shown in Figures 1 to 4, the connector housing 20 has a connector body portion 21, a connector flange portion 22, and a fixing portion 23. The connector body portion 21 is formed in a cylindrical shape that can be fitted into the mounting hole 61 of the panel 60 (see Figures 3 and 4) along the first direction X1. Multiple terminals 30 are housed and held inside the connector body portion 21.

[0024] The connector flange portion 22 protrudes radially outward in a plate shape from the outer circumference of the intermediate portion of the connector body portion 21 along the first axis X. The fixing portion 23 protrudes radially outward in one direction, upward Z1, from the outer circumference of the connector flange portion 22 in a plate shape. The fixing portion 23 has one fixing hole 24 that penetrates along the first axis X.

[0025] As shown in Figures 3 and 4, the connector housing 20 is fixed to the panel 60 by bolts 70 that pass through the fixing holes 24. More specifically, a collar 40 is fixed to the fixing holes 24. The collar 40 is made of metal. The collar 40 is formed in a cylindrical shape. The collar 40 is fixed to the fixing holes 24 such that both axial ends of the collar 40 protrude slightly beyond the opening ends of the fixing holes 24.

[0026] The connector housing 20 is then fixed to the panel 60 by bolts 70 that pass through the collar 40 and are screwed into bolt holes 62 in the panel 60, with the end face of the collar 40 in a first direction X1 in contact with the panel 60.

[0027] (Composition of packing 50) The packing 50 is made of rubber. The packing 50 is attached to the first direction X1 side of the connector body 21.

[0028] The packing 50 has a cylindrical portion 51 that covers the outer circumferential surface of the connector body portion 21 and is positioned between it and the mounting hole 61 of the panel 60, and an annular flange portion 52 that covers the end face of the connector flange portion 22 in the first direction X1 and is positioned between it and the panel 60.

[0029] As shown in Figure 5, the cylindrical portion 51 has a first cylindrical lip portion 53 and a second cylindrical lip portion 54. The first cylindrical lip portion 53 protrudes radially outward when the connector housing 20 is not fixed to the panel 60 (see Figures 3 and 4). The second cylindrical lip portion 54 protrudes radially inward when the connector housing 20 is not fixed to the panel 60. In this embodiment, there are three first cylindrical lip portions 53 provided at intervals along the first axis X, which is the axis of the cylindrical portion 51. In this embodiment, there are four second cylindrical lip portions 54 provided at intervals along the first axis X. Furthermore, the three second cylindrical lip portions 54 in the first direction X1 and the two first cylindrical lip portions 53 in the first direction X1 are arranged alternately from the end of the cylindrical portion 51 in the first direction X1 toward the first opposite direction X2. Furthermore, the first lip portion 53 of one cylindrical section in the first opposite direction X2 and the second lip portion 54 of one cylindrical section in the first opposite direction X2 are positioned at the same location in the direction along the first axis X.

[0030] As shown in Figure 6, the first lip portion 53 of the cylindrical part presses into contact with the inner circumferential surface of the mounting hole 61 of the panel 60 while the connector housing 20 is fixed to the panel 60. The second lip portion 54 of the cylindrical part presses into contact with the outer circumferential surface of the connector body portion 21 while the connector housing 20 is fixed to the panel 60. In this embodiment, the three second lip portions 54 of the cylindrical part in the first direction X1 are pressed into contact with the outer circumferential surface of the connector body portion 21 in such a way that their boundaries disappear, or in other words, there are no gaps between them.

[0031] As shown in Figure 5, the flange portion 52 has a first lip portion 55 and a second lip portion 56. The first lip portion 55 protrudes in a first direction X1 when the connector housing 20 is not fixed to the panel 60 (see Figures 3 and 4). The first lip portion 55 protrudes in a first direction X1 relative to the radially inward portion of the first lip portion 55. The second lip portion 56 protrudes in a first opposite direction X2 when the connector housing 20 is not fixed to the panel 60. The second lip portion 56 protrudes in a first opposite direction X2 relative to the radially inward portion of the second lip portion 56. The first lip portion 55 and the second lip portion 56 are located at the same position in the radial direction of the flange portion 52. Thus, the first lip portion 55 and the second lip portion 56 together constitute a single lip portion. The first lip portion 55 and the second lip portion 56 are formed on the outer edge of the flange portion 52. The first lip portion 55 and the second lip portion 56 are formed by an arc-shaped portion 57 with a cross-sectional shape exceeding 180° when the connector housing 20 is not fixed to the panel 60, and the cross-sectional shape cut along the radial direction. That is, the first lip portion 55 is the portion of the arc portion 57 that protrudes in the first direction X1, and the second lip portion 56 is the portion of the arc portion 57 that protrudes in the first opposite direction X2.

[0032] As shown in Figure 6, the first lip portion 55 presses against the panel 60 when the connector housing 20 is fixed to the panel 60. The second lip portion 56 also presses against the connector flange portion 22 when the connector housing 20 is fixed to the panel 60. That is, the arc portion 57 is sandwiched between the panel 60 and the connector flange portion 22 when the connector housing 20 is fixed to the panel 60. As a result, the first lip portion 55 presses against the panel 60, and the second lip portion 56 presses against the connector flange portion 22. In other words, the combined lip portion of the flange portion 52, consisting of the first lip portion 55 and the second lip portion 56, has a surface that presses against both the panel 60 and the connector flange portion 22.

[0033] Furthermore, the flange portion 52 has a first recess 52a. The first recess 52a is formed radially inward of the first lip portion 55 and is set so as not to come into contact with the panel 60 when the first lip portion 55 is pressed against the panel 60. In other words, the amount of protrusion in the first direction X1 is set so that even when the first lip portion 55 is pressed against the panel 60, the radially inward side of the first lip portion 55 does not come into contact with the panel 60.

[0034] Furthermore, the flange portion 52 has a second recess 52b. The second recess 52b is formed radially inward of the second lip portion 56 and is configured so as not to come into contact with the connector flange portion 22 when the second lip portion 56 is pressed against the connector flange portion 22. In other words, the amount of protrusion in the first opposite direction X2 is configured so that even when the second lip portion 56 is pressed against the connector flange portion 22, the radially inward side of the second lip portion 56 does not come into contact with the connector flange portion 22.

[0035] Furthermore, the cylindrical portion 51 and the flange portion 52 are connected by an inclined wall thickness portion 58, the outer diameter and wall thickness increasing as it moves toward the first opposite direction X2. In other words, the portion connecting the cylindrical portion 51 and the flange portion 52 is an inclined wall thickness portion 58 with a triangular cross-sectional shape when cut along the radial direction, as the outer diameter increases as it moves toward the first opposite direction X2. Note that in this embodiment, the flange portion 52 is the entire portion that extends radially outward from the inclined wall thickness portion 58.

[0036] (Function of connector 20) As shown in Figure 4, the connector 10 configured as described above is fixed to the panel 60 by bolts 70 that pass through the collar 40 and are screwed into bolt holes 62 of the panel 60, with the connector body 21 fitted into the mounting holes 61 of the panel 60.

[0037] Then, the cylindrical portion 51 of the packing 50 is positioned between the outer circumferential surface of the connector body portion 21 and the mounting hole 61 of the panel 60. Also, the flange portion 52 of the packing 50 is positioned between the end face of the connector flange portion 22 in the first direction X1 and the panel 60.

[0038] As shown in Figure 6, the first lip portion 53 of the cylindrical part makes pressure contact with the inner circumferential surface of the mounting hole 61 of the panel 60. The second lip portion 54 of the cylindrical part makes pressure contact with the outer circumferential surface of the connector body portion 21. The first lip portion 55 makes pressure contact with the panel 60. The second lip portion 56 makes pressure contact with the connector flange portion 22. Therefore, for example, liquids containing saltwater are prevented from passing through the outside and inside of the packing 50.

[0039] (Effects of this embodiment) Next, the effects of the above embodiment are described below. (1) The flange portion 52 of the packing 50 has a first lip portion 55 that protrudes in the first direction X1 and presses against the panel 60 when the connector housing 20 is fixed to the panel 60, thereby increasing the waterproofness of that portion through localized press contact. Furthermore, the flange portion 52 has a second lip portion 56 that protrudes in the first opposite direction X2 and presses against the connector flange portion 22 when the connector housing 20 is fixed to the panel 60, thereby increasing the waterproofness of that portion through localized press contact. Thus, it is possible to prevent liquid from passing through the outside and inside of the packing 50.

[0040] (2) The first lip portion 55 and the second lip portion 56 are formed on the outer edge of the flange portion 52 and are composed of arc-shaped portions 57 with a cross-sectional shape exceeding 180° when cut along the radial direction, so that the pressing contact force can be kept constant in the circumferential direction of the packing 50. For example, if the cross-sectional shape of the first lip portion 55 is rectangular, the first lip portion 55 may tilt inward in the radial direction in some parts of the packing 50 in the circumferential direction, or tilt outward in other parts of the circumferential direction, which may cause the pressing contact force to vary in the circumferential direction, but this can be avoided. In other words, since the first lip portion 55 and the second lip portion 56 are composed of arc-shaped portions 57 with a cross-sectional shape exceeding 180°, they do not deform by tilting as in the case of a rectangular shape, so that the pressing contact force can be kept constant in the circumferential direction. Therefore, the waterproof performance can be made higher.

[0041] (3) The cylindrical portion 51 and the flange portion 52 are connected by an inclined wall thickness portion 58, the outer diameter and wall thickness increase as you move toward the first opposite direction X2. As a result, the packing 50 has high rigidity at the inclined wall thickness portion 58. Therefore, compared to the case where the rigidity of the connection portion between the cylindrical portion 51 and the flange portion 52 is low, for example, the packing 50 can be assembled into the connector housing 20 more easily. Also, for example, because the rigidity of the inclined wall thickness portion 58 connecting the cylindrical portion 51 and the flange portion 52 is high, the radial positions of the first lip portion 55 and the second lip portion 56 of the flange portion 52 are stabilized. For example, the radial position of the first lip portion 55 and the second lip portion 56 is prevented from moving radially outward. As a result, the waterproof performance can be made higher and more stable.

[0042] (4) The flange portion 52 has a first recess 52a formed radially inward of the first lip portion 55, which is set so as not to come into contact with the panel 60 when the first lip portion 55 is pressed against the panel 60. Therefore, the pressing force of the first lip portion 55 can be maintained at a high level. That is, for example, if the first recess 52a is not formed and the radially inward side of the first lip portion 55 comes into contact with the panel 60 when the first lip portion 55 is pressed against the panel 60, there is a risk that the pressing force will be dispersed, but this can be avoided. The flange portion 52 also has a second recess 52b formed radially inward of the second lip portion 56, which is set so as not to come into contact with the connector flange portion 22 when the second lip portion 56 is pressed against the connector flange portion 22. Therefore, the pressing force of the second lip portion 56 can be maintained at a high level. For example, in a configuration where the second recess 52b is not formed and the radially inner side of the second lip portion 56 contacts the connector flange portion 22 while the second lip portion 56 is pressed against the connector flange portion 22, there is a risk that the pressing force will be dispersed, but this can be avoided. As a result, the waterproof performance can be further improved.

[0043] (5) The connector housing 20 has a fixing portion 23 that protrudes radially outward from the outer circumference of the connector flange portion 22 and has one fixing hole 24, and is fixed to the panel 60 by a bolt 70 that passes through the fixing hole 24.Therefore, there is a great effect in being able to improve the waterproofness.In other words, in a configuration in which the connector housing 20 is fixed to the panel 60 by a bolt 70 at one point in one fixing hole 24, the entire connector housing 20 is likely to be fixed in an inclined position relative to the panel 60.In this case the waterproofness provided by the packing 50 is likely to decrease, but the waterproofness can be improved by the first lip portion 55 and the second lip portion 56, so for example, waterproofness can be guaranteed.

[0044] (Example of change) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0045] In the above embodiment, the first lip portion 55 and the second lip portion 56 are assumed to be composed of a part of an arc-shaped arc portion 57 with a cross-sectional shape exceeding 180°, but the embodiment is not limited to this. For example, each of the first lip portion 55 and the second lip portion 56 may have a rectangular cross-sectional shape, a triangular shape, or a shape with rounded corners.

[0046] In the above embodiment, the cylindrical portion 51 and the flange portion 52 are connected by an inclined wall thickness portion 58 in which the outer diameter increases and the wall thickness increases as it moves toward the first opposite direction X2, but the embodiment is not limited to this. For example, the cylindrical portion 51 and the flange portion 52 may be connected by a portion with a constant wall thickness.

[0047] In the above embodiment, the flange portion 52 has a first recess 52a formed radially inward of the first lip portion 55 and configured so as not to come into contact with the panel 60 when the first lip portion 55 is pressed against the panel 60. However, the embodiment is not limited to this. That is, when the first lip portion 55 is pressed against the panel 60, the first lip portion 55 may be compressed, causing the portion radially inward of the first lip portion 55 corresponding to the first recess 52a to come into contact with the panel 60 without any gaps.

[0048] Furthermore, although the flange portion 52 is described as having a second recess 52b formed radially inward of the second lip portion 56 and configured so as not to come into contact with the connector flange portion 22 when the second lip portion 56 is pressed against the connector flange portion 22, the configuration is not limited to this. That is, the radially inward side of the second lip portion 56 may come into contact with the connector flange portion 22 without any gaps when the second lip portion 56 is pressed against the connector flange portion 22.

[0049] In the above embodiment, the connector housing 20 is configured to have a fixing portion 23 that protrudes radially outward from the outer circumference of the connector flange portion 22 and has one fixing hole 24. However, it is not limited to this configuration, and for example, it may have two or more fixing holes 24. Of course, if there are two or more fixing holes 24, the connector 10 may have two or more collars 40.

[0050] In the above embodiment, the cylindrical portion 51 is said to have three cylindrical portion first lip portions 53, but it is not limited to this, and it may be configured to have a different number of cylindrical portion first lip portions 53. Also, in the above embodiment, the cylindrical portion 51 is said to have four cylindrical portion second lip portions 54, but it is not limited to this, and it may be configured to have a different number of cylindrical portion second lip portions 54. Furthermore, the positional relationship between the cylindrical portion first lip portions 53 and the cylindrical portion second lip portions 54 may be different from that of the above embodiment.

[0051] In the above embodiment, the connector 10 is attached to the panel 60 by the bolt 70 passing through the collar 40 and being screwed into a bolt hole 62 formed in the panel 60, but the embodiment is not limited to this. For example, the connector 10 may be attached to the panel 60 by the bolt 70 passing through a hole formed in the panel 60 and the collar 40 and being screwed into a nut.

[0052] In the above embodiment, the mounting target was a metal panel 60 in an in-vehicle device, but it is not limited to this, and other mounting targets may be used. The embodiments disclosed herein are illustrative in all respects, and the present invention is not limited to these examples. That is, the scope of the present invention is indicated by the claims, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
