Description

Technical Field

[0001] This invention relates to connectors. Background Technology

[0002] Conventionally, connectors include a connector housing and a seal mounted on the connector housing. The connector housing has a cylindrical connector body and a connector flange that protrudes radially outward from the outer periphery of the connector body (see, for example, Patent Document 1). The seal has: a cylindrical portion covering the outer peripheral surface of the connector body and disposed between the outer periphery and a mounting hole of the mounting object; and an annular flange portion covering the end face of the connector flange and disposed between the end face and the mounting object. Furthermore, the flange portion has a lip that protrudes toward the mounting object, thereby pressing against the mounting object while the connector housing is fixed to the mounting object. In this structure, the lip partially presses against the mounting object, thereby improving the water resistance of that area. Additionally, since the flange portion with the lip is connected to the cylindrical portion covering the outer peripheral surface of the connector body, the radial position of the lip is stable. Therefore, high and stable water resistance is achieved. Existing technical documents Patent documents

[0003] Patent Document 1: Japanese Patent Application Publication No. 2022-89567 Summary of the Invention The problem that the invention aims to solve

[0004] However, in connectors like the described above, the flange portion of the seal has a surface that faces the end face of the connector flange, which is shaped along the end face of the connector flange. Therefore, the force pressing against the end face of the connector flange is not concentrated but dispersed. Consequently, the waterproofing between the flange portion and the connector flange portion is sometimes worse than the waterproofing between the lip portion and the mounted object.

[0005] The purpose of this invention is to provide a connector that improves water resistance. Solution for solving the problem

[0006] The connector of the present invention comprises a connector housing and a seal. The connector housing has a cylindrical connector body portion capable of engaging with a mounting hole of a mounting object along a first direction, and a connector flange portion protruding radially outward from the outer periphery of the connector body portion. The connector housing is fixed to the mounting object. The seal portion has a cylindrical portion and an annular flange portion. The cylindrical portion covers the outer peripheral surface of the connector body portion and is disposed between the outer peripheral surface and the mounting hole. The flange portion covers the end face of the connector flange portion in the first direction and is disposed between the end face and the mounting object. The flange portion has a first lip and a second lip. The first lip protrudes in the first direction to press against the mounting object when the connector housing is fixed to the mounting object. The second lip protrudes in a first opposite direction, which is the opposite direction of the first direction, to press against the connector flange portion when the connector housing is fixed to the mounting object.

Detailed Implementation

[0009] [Description of embodiments of the present invention] First, embodiments of the present invention will be described. The connector of the present invention [1] The connector housing includes a connector housing and a seal. The connector housing has a cylindrical connector body portion that can be fitted with a mounting hole of a mounting object along a first direction, and a connector flange portion that protrudes radially outward from the outer periphery of the connector body portion. The connector housing is fixed to the mounting object. The seal portion has a cylindrical portion and an annular flange portion. The cylindrical portion covers the outer peripheral surface of the connector body portion and is disposed between the outer peripheral surface and the mounting hole. The flange portion covers the end face of the connector flange portion in the first direction and is disposed between the end face and the mounting object. The flange portion has a first lip and a second lip. The first lip protrudes in the first direction to press against the mounting object when the connector housing is fixed to the mounting object. The second lip protrudes in a first opposite direction, which is the opposite direction of the first direction, to press against the connector flange portion when the connector housing is fixed to the mounting object.

[0010] According to this structure, the flange portion of the seal has a first lip, which protrudes in a first direction and presses against the mounting object when the connector housing is fixed to the mounting object. Therefore, this localized pressing contact improves the water resistance of this area. Furthermore, the flange portion of the seal has a second lip, which protrudes in the opposite direction to the first lip and presses against the connector flange portion when the connector housing is fixed to the mounting object. Therefore, this localized pressing contact improves the water resistance of this area. Thus, liquid can be prevented from passing through the outer and inner sides of the seal.

[0011] [2] In the above [1], the first lip and the second lip may also be formed by an arc portion formed on the outer edge of the flange portion and cut off radially with a cross-sectional shape of more than 180°.

[0012] According to this structure, since the first and second lips are composed of arc-shaped portions with a cross-sectional shape exceeding 180° formed on the outer edge of the flange and cut radially, the pressing contact force can be kept constant in the circumferential direction of the seal. For example, if the cross-sectional shape of the first lip is rectangular, the first lip may tilt radially inward in a portion of the circumferential direction of the seal, or radially outward in other portions, potentially causing a deviation in the pressing contact force in the circumferential direction, but this can be avoided. In other words, since the first and second lips are composed of arc-shaped portions with a cross-sectional shape exceeding 180°, they do not deform in a tilting manner as in the case of a rectangle, thus keeping the pressing contact force constant in the circumferential direction of the seal. Therefore, the waterproof performance can be further improved.

[0013] [3] In either [1] or [2] above, the cylindrical portion and the flange portion may be connected by an inclined wall thickness portion, and the more the inclined wall thickness portion is directed toward the first opposite direction, the larger the outer diameter and the thicker the wall thickness.

[0014] According to this structure, the cylindrical portion and the flange portion are connected by an inclined wall thickness portion. The more the inclined wall thickness portion faces the first opposite direction, the larger its outer diameter and the thicker its wall, thus increasing the rigidity of the seal at the inclined wall thickness portion. Therefore, for example, compared to the case where the rigidity of the connection between the cylindrical portion and the flange portion is low, the assemblability of the seal to the connector housing becomes better. Furthermore, for example, due to the high rigidity of the inclined wall thickness portion connecting the cylindrical portion and the flange portion, the radial positions of the first lip and the second lip of the flange portion are stable. For example, radial displacement of the first lip and the second lip to the radially outward direction can be suppressed. Therefore, the waterproof performance is higher and more stable.

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

[0016] According to this structure, the flange portion has a first recess formed radially inside the first lip. This first recess is configured to not contact the mounting object when the first lip is pressed against it, thus maintaining a higher pressing force. For example, in a structure where the first recess is not formed and the radially inside the first lip contacts the mounting object when the first lip is pressed against it, the pressing force might be dispersed, but this is avoided. Furthermore, the flange portion has a second recess formed radially inside the second lip. This second recess is configured to not contact the connector flange when the second lip is pressed against it, thus maintaining a higher pressing force. For example, in a structure where the second recess is not formed and the radially inside the second lip contacts the connector flange when the second lip is pressed against it, the pressing force might be dispersed, but this is avoided. This results in higher water resistance.

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

[0018] According to this structure, the connector housing has a fixing part that protrudes radially outward from the outer periphery of the connector flange and has a fixing hole. The connector housing is fixed to the mounting object by a bolt passing through the fixing hole, thus greatly improving water resistance. That is, in the structure where the connector housing is fixed to the mounting object by a bolt at one fixing hole, the connector housing as a whole can be easily fixed in an inclined state relative to the mounting object. In this case, the water resistance of the seal is easily reduced, but because the first lip and the second lip can improve water resistance, for example, water resistance can be guaranteed.

[0019] [Detailed Description of Embodiments of the Invention] Specific examples of the connector of the present invention will be described below with reference to the accompanying drawings. In the drawings, for ease of description, some parts of the structure are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts sometimes differ in the drawings.

[0020] The term "cylindrical" as used in this specification includes not only shapes with a continuous circumferential wall, but also shapes formed by combining multiple components, and shapes with a notch in a portion of the circumference, such as a C-shape. The outer circumferential shape of a "cylindrical" includes, but is not limited to, circles, ellipses, and polygons with pointed or rounded corners. A "cylindrical" shape, when viewed from above, is a shape with a through hole, including cylinders whose outer circumferential shape and the inner circumferential shape of the through hole are the same shape, or cylinders whose outer circumferential shape and the inner circumferential shape of the through hole are different shapes. A "cylindrical" shape includes a cylinder having a predetermined length extending along an axial direction, regardless of its length, where the axial direction extends through the center axis of the through hole. Additionally, the term "ring-shaped" as used in this specification sometimes refers to any structure forming a ring, or a continuous shape without ends, and a generally ring-shaped structure with a gap, such as a C-shape. The shape of a "ring-shaped" shape includes circles, ellipses, and polygons with pointed or rounded corners, but is not limited to these. Furthermore, the terms "first," "second," "third," etc., used in this specification are only used to distinguish objects and do not constitute a ranking of objects. This invention is not limited to these examples, but is shown through the claims and is intended to include all variations within the meaning and scope equivalent to the claims.

[0021] (Structure of connector 10) like Figure 1 and Figure 2As shown, connector 10 includes connector housing 20, multiple terminals 30, collar 40, and seal 50. Furthermore, in each figure, a first axis X, a second axis Y orthogonal to the first axis X, and a third axis Z orthogonal to both the first axis X and the second axis Y are illustrated. Additionally, in the figures, a first direction X1 along the first axis X and a first reverse direction X2 opposite to the first direction X1 are illustrated. Furthermore, in the figures, an upper direction Z1 along the third axis Z and a lower direction Z2 opposite to the upper direction Z1 are illustrated.

[0022] like Figure 3 and Figure 4 As shown, in this embodiment, the connector 10 is mounted, for example, to a metal panel 60 in a vehicle-mounted device via bolts 70. The vehicle-mounted device is installed in a vehicle. The panel 60 has a mounting hole 61 extending along a first axis X and a bolt hole 62 extending along the first axis X.

[0023] (Structure of connector housing 20) The connector housing 20 is made of resin. like Figures 1 to 4 As shown, 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 configured to be able to interact with the panel 60 (see reference 60) along the first direction X1. Figure 3 and Figure 4 The mounting hole 61 fits into the cylindrical shape. Multiple terminals 30 are housed and held inside the connector body 21.

[0024] The connector flange 22 protrudes radially outward from the outer periphery of the middle portion of the connector body 21 along the first axis X. The fixing portion 23 protrudes radially outward from the outer periphery of the connector flange 22 in an upward Z1 direction. The fixing portion 23 has a fixing hole 24 extending along the first axis X.

[0025] And, as Figure 3 and Figure 4 As shown, the connector housing 20 is fixed to the panel 60 by bolts 70 passing through the fixing hole 24. Specifically, a collar 40 is fixed in the fixing hole 24. The collar 40 is made of metal and is cylindrical. The collar 40 is fixed to the fixing hole 24 such that both ends of the collar 40 protrude slightly outward from the open end of the fixing hole 24 in the axial direction.

[0026] Furthermore, when the end face of the collar 40 in the first direction X1 is in contact with the panel 60, the connector housing 20 is fixed to the panel 60 by a bolt 70 that passes through the collar 40 and engages with the bolt hole 62 of the panel 60.

[0027] (Structure of seal 50) The seal 50 is made of rubber. The seal 50 is installed on the first direction X1 side of the connector body 21.

[0028] The seal 50 has: a cylindrical portion 51 that covers the outer peripheral surface of the connector body portion 21 and is disposed between the outer peripheral surface 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 disposed between the end face and the panel 60.

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

[0030] like Figure 6 As shown, the first lip 53 of the cylindrical portion presses against the inner peripheral surface of the mounting hole 61 of the panel 60 when the connector housing 20 is fixed to the panel 60. Additionally, the second lip 54 of the cylindrical portion presses against the outer peripheral surface of the connector body 21 when the connector housing 20 is fixed to the panel 60. Furthermore, in this embodiment, the three second lips 54 of the cylindrical portion in the first direction X1, when pressing against the outer peripheral surface of the connector body 21, press against the outer peripheral surface of the connector body 21 in such a way that their respective dividing lines disappear, in other words, the gaps between them disappear.

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

[0032] like Figure 6 As shown, the first lip 55 presses against the panel 60 when the connector housing 20 is fixed to the panel 60. Additionally, the second lip 56 presses against the connector flange 22 when the connector housing 20 is fixed to the panel 60. That is, the arcuate portion 57 is sandwiched between the panel 60 and the connector flange 22 when the connector housing 20 is fixed to the panel 60. Thus, the first lip 55 presses against the panel 60, and the second lip 56 presses against the connector flange 22. In other words, a single lip that combines the first lip 55 and the second lip 56 of the flange 52 has a surface that presses against both the panel 60 and the connector flange 22.

[0033] Additionally, the flange portion 52 has a first recess 52a. The first recess 52a is formed radially inward of the first lip portion 55, and the first recess 52a is configured to not contact the panel 60 when the first lip portion 55 is pressed against the panel 60. In other words, the amount of protrusion of the first lip portion 55 in the first direction X1 is set such 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 contact the panel 60.

[0034] Additionally, 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 not to contact the connector flange portion 22 when the second lip portion 56 is pressed against it. In other words, the amount of protrusion of the second lip portion 56 in the first reverse direction X2 is set such 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 contact 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 inclined wall thickness portion 58 has a larger outer diameter and a thicker wall as it moves towards the first opposite direction X2. That is, the portion connecting the cylindrical portion 51 and the flange portion 52 is formed such that the outer diameter increases as it moves towards the first opposite direction X2, resulting in an inclined wall thickness portion 58 with a triangular cross-sectional shape when cut radially. In addition, in this embodiment, the flange portion 52 is an integral portion that extends radially outward compared to the inclined wall thickness portion 58.

[0036] (Function of connector 20) like Figure 4 As shown, the connector 10 configured as described above is fixed to the panel 60 by a bolt 70 that passes through the collar 40 and engages with the bolt hole 62 of the panel 60 when the main body 21 of the connector is engaged with the mounting hole 61 of the panel 60.

[0037] Therefore, the cylindrical portion 51 of the seal 50 is disposed between the outer peripheral surface of the connector body portion 21 and the mounting hole 61 of the panel 60. In addition, the flange portion 52 of the seal 50 is disposed between the end face of the connector flange portion 22 in the first direction X1 and the panel 60.

[0038] And, as Figure 6 As shown, the first lip 53 of the cylindrical portion presses against the inner peripheral surface of the mounting hole 61 of the contact panel 60. Additionally, the second lip 54 of the cylindrical portion presses against the outer peripheral surface of the contact connector body 21. Furthermore, the first lip 55 presses against the contact panel 60. Additionally, the second lip 56 presses against the contact connector flange 22. Therefore, for example, liquids including salt water can be prevented from passing through the outer and inner sides of the seal 50.

[0039] (Effects of this implementation method) Next, the effects of the above-described embodiments will be described. (1) The flange portion 52 of the seal 50 has a first lip 55, which protrudes in a first direction X1 and presses against the panel 60 when the connector housing 20 is fixed to the panel 60. Therefore, the water resistance of this part can be improved by localized pressing contact. In addition, the flange portion 52 has a second lip 56, which protrudes in a first opposite direction X2 and presses against the connector flange portion 22 when the connector housing 20 is fixed to the panel 60. Therefore, the water resistance of this part can be improved by localized pressing contact. Thus, liquid can be prevented from passing through the outer and inner sides of the seal 50.

[0040] (2) The first lip 55 and the second lip 56 are formed by arcuate portions 57 with a cross-sectional shape exceeding 180°, formed on the outer edge of the flange 52 and cut radially. Therefore, the pressing contact force can be kept constant in the circumferential direction of the seal 50. For example, if the cross-sectional shape of the first lip 55 were rectangular, a portion of the first lip 55 would tilt radially inward in the circumferential direction of the seal 50, or another portion would tilt radially outward in the circumferential direction, potentially causing a deviation in the pressing contact force in the circumferential direction. However, this situation can be avoided. In other words, since the first lip 55 and the second lip 56 are formed by arcuate portions 57 with a cross-sectional shape exceeding 180°, they do not deform in a tilting manner as in the case of a rectangle, thus keeping the pressing contact force constant in the circumferential direction. Therefore, waterproofness is further improved.

[0041] (3) The cylindrical portion 51 and the flange portion 52 are connected by an inclined wall thickness portion 58. The more the inclined wall thickness portion 58 faces the first opposite direction X2, the larger its outer diameter and the thicker its wall, thus increasing the rigidity of the seal 50 at the inclined wall thickness portion 58. Therefore, for example, compared to the case where the rigidity of the connection portion between the cylindrical portion 51 and the flange portion 52 is low, the assemblability of the seal 50 to the connector housing 20 becomes better. In addition, for example, because of the high rigidity of the inclined wall thickness portion 58 connecting the cylindrical portion 51 and the flange portion 52, the radial positions of the first lip 55 and the second lip 56 of the flange portion 52 are stable. For example, the radial position of the first lip 55 and the second lip 56 can be prevented from moving radially outward. Therefore, the waterproof performance is higher and more stable.

[0042] (4) The flange portion 52 has a first recess 52a, which is formed radially inside the first lip 55 and is configured not to contact the panel 60 when the first lip 55 is pressed against the panel 60. Therefore, the pressing force of the first lip 55 can be maintained more strongly. That is, for example, in a structure where the first recess 52a is not formed and the radially inside the first lip 55 is in contact with the panel 60 when the first lip 55 is pressed against the panel 60, the pressing force may be dispersed, but this situation can be avoided. In addition, the flange portion 52 has a second recess 52b, which is formed radially inside the second lip 56 and is configured not to contact the connector flange 22 when the second lip 56 is pressed against the connector flange 22. Therefore, the pressing force of the second lip 56 can be maintained more strongly. For example, in a structure where the second recess 52b is not formed and the radially inner side of the second lip 56 contacts the connector flange 22 while the second lip 56 is pressing against the connector flange 22, the pressing force may be dispersed, but this can be avoided. This results in higher water resistance.

[0043] (5) The connector housing 20 has a fixing portion 23, which protrudes radially outward from the outer periphery of the connector flange portion 22 and has a fixing hole 24. The connector housing 20 is fixed to the panel 60 by a bolt 70 passing through the fixing hole 24. Therefore, the waterproof performance is greatly improved. That is, in the structure where the connector housing 20 is fixed to the panel 60 by a bolt 70 at a fixing hole 24, the connector housing 20 as a whole is easily fixed in an inclined state relative to the panel 60. In this case, the waterproof performance of the seal 50 is easily reduced, but because the waterproof performance can be improved by the first lip 55 and the second lip 56, waterproof performance can be guaranteed, for example.

[0044] (Modified Example) The above embodiments can be implemented with the following modifications. The above embodiments and the following variations can be combined with each other within the scope of technical inconsistency.

[0045] In the above embodiment, the first lip 55 and the second lip 56 are formed by a portion of an arc portion 57 with a cross-sectional shape of more than 180°, but are not limited thereto. For example, the cross-sectional shape of the first lip 55 and the second lip 56 may also be rectangular, triangular, or have 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. The more the inclined wall thickness portion 58 is directed towards the first opposite direction X2, the larger the outer diameter and the thicker the wall, but it is not limited to this. For example, the cylindrical portion 51 and the flange portion 52 may also be connected by a portion with a fixed wall thickness.

[0047] In the above embodiment, the flange portion 52 has a first recess 52a, which is configured not to contact the panel 60 when the first lip 55, formed on the radially inner side of the first lip 55, presses against the panel 60, but is not limited thereto. That is, it may also be configured such that the first lip 55 is flattened when it presses against the panel 60, so that the radially inner side of the first lip 55 and the portion corresponding to the first recess 52a contact the panel 60 without gap.

[0048] Additionally, the flange portion 52 has a second recess 52b, which is formed radially inside the second lip portion 56. This second recess 52b is configured not to contact the connector flange portion 22 when the second lip portion 56 is pressed against it, but is not limited to this configuration. That is, it can also be configured such that, when the second lip portion 56 is pressed against the connector flange portion 22, the radially inside side of the second lip portion 56 contacts the connector flange portion 22 without any gap.

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

[0050] In the above embodiment, the cylindrical portion 51 has three first cylindrical lips 53, but is not limited thereto; it can be configured with different numbers of first cylindrical lips 53. Additionally, the cylindrical portion 51 has four second cylindrical lips 54, but is not limited thereto; it can also be configured with different numbers of second cylindrical lips 54. Furthermore, the positional relationship between the first cylindrical lips 53 and the second cylindrical lips 54 in the above embodiment can also be different.

[0051] In the above embodiment, the bolt 70 is configured to install the connector 10 to the panel 60 by passing through the collar 40 and engaging with the bolt hole 62 formed in the panel 60, but is not limited thereto. For example, the bolt 70 may also be configured to install the connector 10 to the panel 60 by passing through the hole formed in the panel 60 and the collar 40 and engaging with the nut.

[0052] In the above embodiment, the installation object is set as a metal panel 60 in the vehicle-mounted equipment, but it is not limited to this and can also be set as other installation objects. The embodiments disclosed herein are illustrative in all respects, and the invention is not limited to these illustratives. That is, the scope of the invention is set forth in the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.
