Description

[Technical Field]

[0001] The present invention relates to a cap that is to be removably attached to an opening of an attachment target, and a capped unit that uses the cap. [Background technology]

[0002] Charging connectors have been proposed for supplying power from outside the vehicle (charging) batteries mounted on vehicles such as electric vehicles and plug-in hybrid vehicles. This type of connector is generally also called a charging inlet (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-026288 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional charging inlet described above has an opening where terminals are provided and a hinged lid for exposing or sealing the opening as needed. From the perspective of simplifying the charging inlet, it is conceivable to replace the hinged lid with a cap that can be attached to or detached from the opening. However, generally, the task of separating a cap from an opening tends to be more difficult than the task of fitting the cap into the opening. This is because, in the former task, it is easy for an operator to apply force to the cap to push the cap into the opening, whereas, in the latter task, it is difficult for an operator to apply force to the cap to pull it out of the opening. For these reasons, there is a demand for a cap that can be easily separated from the opening of a charging inlet while retaining its original functions (e.g., dustproofness, waterproofness, etc.). Furthermore, as can be understood from this description, it is desirable for a cap to combine its original functions with the ability to be easily separated from any opening to which it is attached, regardless of the charging inlet.

[0005] An object of the present invention is to provide a cap that can be easily separated from an opening to which it is attached while retaining its original function as a cap, and a capped unit that uses the cap. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the cap and capped unit according to the present invention are characterized as follows.

[0007] A cap to be detachably attached to an opening of an attachment target, a body portion to be fitted into the opening; an operating portion that protrudes from the main body portion and extends toward the outside of the opening, The operation unit includes: a pair of plate-like portions having an operation point to which an external force for removing the cap from the opening is applied and extending in a protruding direction of the operation portion; and a connecting portion extending in a direction intersecting the protruding direction and connecting the pair of plate-like portions at a position closer to the protruding ends of the pair of plate-like portions than the operation point, and configured so that when the external force is applied, the operation point is elastically displaced to a position where it overlaps with the connecting portion in the protruding direction; It's a cap.

[0008] The cap described above; and an attachment object having an opening to which the cap is attached. It must be a capped unit. [Effects of the Invention]

[0009] According to the cap and capped unit of the present invention, the cap's main body is fitted into the opening of the target, thereby sealing the opening. This allows the cap's inherent functions (e.g., dustproofness, waterproofness, etc.) to be realized. Furthermore, when the cap is fitted into the opening, the user can apply an external force to the operation unit protruding from the cap's main body to separate the cap from the opening. More specifically, when an external force is applied so as to sandwich the pair of plate-shaped portions of the operation unit in the thickness direction (e.g., when the user pinches the pair of plate-shaped portions with their fingers), the operation points of the plate-shaped portions elastically displace to a position where they overlap with the connecting portion connecting the plate-shaped portions in the protruding direction of the operation unit. In this state, when an external force is applied to the operation unit in a direction away from the opening (e.g., when the user tries to pull the cap out of the opening while pinching the pair of plate-shaped portions with their fingers), the external force acts not only on the plate-shaped portions but also on the connecting portion (e.g., the user's fingers get caught on the connecting portion). This makes it easier for the user to apply an external force to the operation unit. Therefore, the user can easily separate the cap from the opening. Therefore, the cap and capped unit of the present invention can be easily separated from the opening to which it is attached while retaining the original function of a cap.

[0010] The present invention has been briefly described above. The details of the present invention will become clearer by reading the detailed description of the invention below in conjunction with the accompanying drawings. [Brief explanation of the drawings]

[0012] <Embodiment> Hereinafter, a capped connector 3 according to an embodiment of the present invention, including a cap 1 according to an embodiment of the present invention, will be described with reference to the drawings. As shown in FIG. 1, the capped connector 3 is composed of the cap 1 and a connector 2 to which the cap 1 is attached. The connector 2 is installed in a vehicle such as a plug-in hybrid vehicle or an electric vehicle, and is connected to an electric wire extending from a battery mounted on the vehicle. The connector 2 is also called a charging inlet. By fitting a mating connector (a so-called charging gun) into the fitting recess 21 of the connector 2 (see FIG. 1), power is supplied to the battery from outside the vehicle, and the battery is charged.

[0013] For the sake of convenience, the following definitions are used for "front," "rear," "left," "right," "upper," and "lower" as shown in FIG. 1 and elsewhere. The "front-rear direction," "left-right direction," and "upper-lower direction" are perpendicular to one another. The front-rear direction coincides with the mating direction of the connector 2 and the mating connector (not shown), and the front side of the mating direction (the side approaching the mating connector) as viewed from the connector 2 is referred to as the "front side," while the release side of the mating direction (the side moving away from the mating connector) as viewed from the connector 2 is referred to as the "rear side." Note that the "front-rear direction," "left-right direction," and "upper-lower direction" are defined merely for the sake of convenience, and do not necessarily correspond to the front-rear direction, left-right direction, and upper-lower direction of the vehicle when the connector 2 is mounted on the vehicle.

[0014] As shown in Fig. 1, the connector 2 to which the cap 1 is attached includes a pair of left and right terminals 10 and a housing 20 that houses the pair of left and right terminals 10. One ends of a pair of left and right electric wires 4 are connected to the pair of left and right metal terminals (female terminals) 10, respectively. The other ends of the pair of left and right electric wires 4 are connected to, for example, a battery (not shown). In this example, the housing 20 is formed by combining multiple resin parts, etc., but it may also be formed from a single resin part.

[0015] A mating recess 21 that opens forward and is recessed rearward is defined at the front end of the housing 20. In this example, the mating recess 21 is a recess that has a circular shape when viewed from the front. The housing 20 is provided with a pair of left and right cylindrical terminal accommodating portions 22 that protrude forward within the mating recess 21 and correspond to the pair of left and right terminals 10. Each terminal accommodating portion 22 has an internal space that penetrates in the front-to-rear direction. The pair of left and right terminals 10 are accommodated in the pair of left and right terminal accommodating portions 22 of the housing 20, respectively. By mating a mating connector with the mating recess 21 of the housing 20, a pair of left and right male terminals (not shown) belonging to the mating connector are connected to the pair of left and right terminals 10, respectively, and power is supplied to the battery from outside the vehicle.

[0016] The cap 1 is a part that is removably fitted into the mating recess 21 of the housing 20, and by being fitted into the mating recess 21 and covering the opening of the mating recess 21, it serves the functions of protecting the pair of left and right terminals 10 located within the mating recess 21, as well as preventing dust and water from entering the mating recess 21.

[0017] The cap 1 is typically made of elastomer (or rubber) and is an elastically deformable molded body. As shown in Figures 2 and 3, the cap 1 is composed of a main body 30 that is fitted into the fitting recess 21 to cover the opening of the fitting recess 21, and an operating part 40 that protrudes forward from the main body 30 and extends outward from the fitting recess 21.

[0018] 2 and 3 , the main body 30 is composed of a flat, disc-shaped central wall 31 extending in a direction perpendicular to the front-to-rear direction, a tapered wall 32 extending obliquely from the entire circumference of the outer periphery of the central wall 31 toward the front and radially outward, an annular flange 33 extending radially outward from the entire circumference of the outer periphery of the tapered wall 32, and a substantially cylindrical annular portion 34 extending rearward from the entire circumference of the outer periphery of the tapered wall 32. When the cap 1 is attached to the fitting recess 21, the central wall 31 and the tapered wall 32 cover the opening of the fitting recess 21, the annular flange 33 faces the end face (front end face) of the opening edge of the fitting recess 21, and the annular portion 34 faces the inner circumferential side surface of the fitting recess 21.

[0019] The operating portion 40 is a portion that is operated (external force is applied) by a user's finger or the like when attaching or detaching the cap 1 to or from the fitting recess 21 of the housing 20. As shown in FIGS. 2 to 4 , the operating portion 40 has a cylindrical portion 41 extending in the front-to-rear direction and a connecting portion 42 that connects the cylindrical portion 41 to the central wall portion 31 of the main body 30. The cylindrical portion 41 has an elongated hole shape that is long in the left-to-right direction when viewed from the front, and includes a pair of upper and lower plate-like portions 44 that are substantially rectangular flat plates and extend in the front-to-rear direction. The pair of upper and lower plate-like portions 44 are arranged opposite each other with a gap in the up-down direction. The connecting portion 42 connects the cylindrical portion 41 and the central wall portion 31 so that the axes of the cylindrical portion 41 and the central wall portion 31 are coaxially arranged. In this example, the connecting portion 42 extends outward as it approaches the central wall portion 31 from the cylindrical portion 41 (moving from the front to the rear).

[0020] A flat plate-shaped connecting portion 43 that connects the inner peripheral surface of the cylindrical portion 41 around the entire circumference of the cylindrical portion 41 is provided at a position on the main body portion 30 side (rear side) a predetermined distance from the protruding end (front end) of the cylindrical portion 41 (plate-shaped portion 44). In other words, the connecting portion 43 is provided at a position between the protruding end (front end) and the base end (rear end) of the cylindrical portion 41 (plate-shaped portion 44). The connecting portion 43 extends in the vertical direction at the aforementioned position in the vertical direction, and connects the pair of upper and lower plate-shaped portions 44 in the vertical direction.

[0021] In this way, by providing the connecting portion 43 at a position in the front-rear direction on the main body 30 side a predetermined distance from the protruding end of the tubular portion 41 (plate-like portion 44), a recess 46 that is recessed rearward and open forward is defined by the inner circumferential surface of the tubular portion 41 on the protruding end side (front side) of the connecting portion 43 and the connecting portion 43. To improve drainage of water that accumulates in this recess 46, a pair of left and right notches 45 are formed in lower parts near both left and right ends of the protruding end of the tubular portion 41 that define the recess 46. In this example, as can be seen from FIG. 4, the thickness of the tubular portion 41 (the pair of upper and lower plate-like portions 44), the thickness of the connecting portion 43, and the thickness of the central wall portion 31 of the main body 30 are the same.

[0022] When fitting the cap 1 into the fitting recess 21 of the housing 20, the user pinches the pair of upper and lower plate-like portions 44 of the operating portion 40 of the cap 1 with their fingers, and in this state, pushes the cap 1 into the fitting recess 21 (applying a rearward external force to the operating portion 40) until the annular flange portion 33 of the main body portion 30 abuts against the end face (front end face) of the opening edge of the fitting recess 21 so that the annular portion 34 of the main body portion 30 is inserted into the fitting recess 21. This allows the cap 1 to be fitted into the fitting recess 21.

[0023] On the other hand, when the cap 1 is fitted into the fitting recess 21 of the housing 20, the user can pinch the pair of upper and lower plate-shaped portions 44 of the cap 1 with their fingers and, in this state, apply a forward external force to the operation unit 40, thereby removing (separating) the cap 1 from the fitting recess 21. Specifically, as shown in FIG. 5 , when the user pinches a pair of upper and lower operation points P, which are located closer to the main body 30 (rearward) than the connecting portion 43 of the pair of upper and lower plate-shaped portions 44, with their fingers, so as to pinch them vertically, and an external force is applied to the pair of plate-shaped portions 44 (see the white arrows in FIG. 5 ), the pair of plate-shaped portions 44 elastically deform in a direction approaching each other in the vertical direction. In other words, the operation points P of the pair of plate-shaped portions 44 elastically displace to positions where they overlap the connecting portion 43, which connects the pair of plate-shaped portions 44, in the protruding direction (front-rear direction) of the operation unit 40. That is, the operation unit 40 elastically deforms in this manner. In this state, when a user pinches the pair of plate-like portions 44 with their fingers and pulls the cap 1 out of the fitting recess 21, and an external force is applied to the operating portion 40 in a forward direction (away from the fitting recess 21), the user's fingers get caught on the connecting portion 43, and the external force is applied not only to the plate-like portions 44 but also to the connecting portion 43 (see the black arrow in FIG. 5 ). This makes it easier for the user to apply an external force to the operating portion 40, and the user can easily separate the cap 1 from the fitting recess 21. In this example, the connecting portion 43 is provided not at the protruding end (front end) of the cylindrical portion 41 but at a predetermined distance from the protruding end of the cylindrical portion 41 toward the main body 30 (rear side) in the front-to-rear direction so that the user can easily apply an external force to the connecting portion 43 to separate the cap 1, depending on specifications such as the size of the cap 1 and the length of the operating portion 40.

[0024] <Actions and Effects> As described above, according to the cap 1 and the capped connector 3 of this embodiment, the main body 30 of the cap 1 is fitted into the fitting recess 21 of the attachment target (connector 2), thereby sealing the fitting recess 21. This allows the cap 1 to exhibit its original functions (e.g., dustproofness, waterproofness, etc.). Furthermore, when a user applies an external force for separation to the operation unit 40 protruding from the main body 30 of the cap 1, the cap 1 attached to the fitting recess 21 of the attachment target (connector 2) can be separated from the fitting recess 21. Specifically, when an external force is applied so as to pinch the pair of plate-shaped portions 44 of the operation unit 40 (e.g., when the user pinches the pair of plate-shaped portions 44 with their fingers), the operation unit 40 elastically deforms so that the operation point P of the plate-shaped portions 44 and the connecting portion 43 connecting the plate-shaped portions 44 overlap in the protruding direction of the operation unit 40. In this state, if an external force is applied to the operating portion 40 in a direction away from the fitting recess 21 (for example, if a user pulls the cap 1 out of the fitting recess 21 while pinching the pair of plate-like portions 44 with their fingers), the external force will be applied not only to the plate-like portions 44 but also to the connecting portion 43. This makes it easier to apply an external force to the operating portion 40 (for example, the user's fingers get caught on the connecting portion 43), allowing the cap 1 to be easily and properly separated from the fitting recess 21. Therefore, the cap 1 and capped connector 3 according to this embodiment enable the cap 1 to be properly separated from the fitting recess 21 of the connector 2 to which it is attached.

[0025] Furthermore, in the cap 1 according to this embodiment, the connecting portion 43 is provided at a position away from the protruding ends of the pair of plate-like portions 44 toward the main body portion 30. This allows the connecting portion 43 to be provided at a position where the user can easily apply an external force for separation, depending on the specifications of the cap 1, such as the size and length of the operating portion. This improves the workability of separating the cap 1.

[0026] <Other aspects> It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. are possible as appropriate. Furthermore, the material, shape, dimensions, number, location, etc. of each component in the above-described embodiments are arbitrary as long as they can achieve the present invention, and are not limited thereto.

[0027] For example, in the above embodiment, the thickness of the cylindrical portion 41 (the pair of upper and lower plate-like portions 44), the thickness of the connecting portion 43, and the thickness of the central wall portion 31 of the main body portion 30 are the same. In contrast, as in a first modified example shown in FIGS. 6 and 7 , the thickness t1 of the cylindrical portion 41 (the pair of upper and lower plate-like portions 44) may be thinner than the thickness t3 of the central wall portion 31 of the main body portion 30. This allows the pair of plate-like portions 44 to be easily deformed by an external force without impairing the function of the cap 1. In other words, the operating portion 40 can be easily elastically deformed so that the operating point P of the pair of plate-like portions 44 and the connecting portion 43 connecting the pair of plate-like portions 44 overlap in the protruding direction (front-rear direction) of the operating portion 40. As a result, when an external force is applied so as to sandwich the pair of plate-shaped portions 44 (for example, when a user pinches the pair of plate-shaped portions 44 with their fingers), the pair of plate-shaped portions 44 easily elastically deform in a direction toward each other in the vertical direction (see the white arrows in FIG. 8 ). In this state, when an external force is applied to the operation portion 40 in a direction away from the fitting recess 21 (for example, when a user pulls the cap 1 out of the fitting recess 21 while pinching the pair of plate-shaped portions 44 with their fingers), the external force acts not only on the plate-shaped portions 44 but also on the connecting portion 43 (see the black arrows in FIG. 8 ), as in the above embodiment, and the external force is easily applied to the operation portion 40 (for example, when the user's fingers get caught on the connecting portion 43). This makes it easy to separate the cap 1 from the fitting recess 21.

[0028] In the first modified example shown in FIGS. 6 to 8 , the thickness t2 of the connecting portion 43 is thinner than the thickness t3 of the central wall portion 31 of the main body portion 30. Furthermore, the thickness t1 of the tubular portion 41 (the pair of upper and lower plate-like portions 44) and the thickness t2 of the connecting portion 43 are the same. In this way, by making the thickness t1 of the tubular portion 41 (the pair of upper and lower plate-like portions 44) and the thickness t2 of the connecting portion 43 the same in the operating portion 40, the ease of removal from the mold (moldability) in the front-to-rear direction during molding of the cap 1 can be improved. However, the thickness t1 of the tubular portion 41 (the pair of upper and lower plate-like portions 44) may be thinner than the thickness t3 of the central wall portion 31 of the main body portion 30, and the thickness t2 of the connecting portion 43 may not be thinner than the thickness t3 of the central wall portion 31 of the main body portion 30. In addition, in the first modified example shown in Figures 6 to 8 (the same applies to the second modified example shown in Figure 9 described later), the connecting portion 43 is provided at the protruding end (front end) of the tubular portion 41 (a pair of upper and lower plate-shaped portions 44).

[0029] Furthermore, in the first modified example shown in FIGS. 6 to 8 , the thickness of the tubular portion 41 (the pair of upper and lower plate-like portions 44) is constant regardless of the position of the tubular portion 41 (the pair of upper and lower plate-like portions 44) in the front-rear direction. In contrast, as in the second modified example shown in FIG. 9 , the thickness of the tubular portion 41 (the pair of upper and lower plate-like portions 44) may be changed depending on the position of the tubular portion 41 (the pair of upper and lower plate-like portions 44) in the front-rear direction. In the second modified example shown in FIG. 9 , the inner wall surface of the tubular portion 41 (the pair of upper and lower plate-like portions 44) is inclined by an angle θ with respect to the front-rear direction, so that the thickness of the tubular portion 41 (the pair of upper and lower plate-like portions 44) gradually decreases from the front side to the rear side of the tubular portion 41 (the pair of upper and lower plate-like portions 44). As a result, the thickness of the tubular portion 41 (the pair of upper and lower plate-like portions 44) is thinner than the thickness of the central wall portion 31 of the main body 30.

[0030] 9, when an external force is applied so as to sandwich the pair of plate-shaped portions 44 (for example, when a user pinches the pair of plate-shaped portions 44 with their fingers), the pair of plate-shaped portions 44 easily elastically deform in a direction toward each other in the vertical direction. As a result, for the same reason as in the first modified example shown in FIGS. 6 and 7, the cap 1 can be easily and properly separated from the fitting recess 21.

[0031] Here, the features of the embodiments of the cap 1 and the capped connector 3 according to the present invention described above will be briefly summarized and listed below in [1] to [4].

[0032] [1] A cap (1) to be detachably attached to an opening (21) of an attachment object (2), a main body (30) to be fitted into the opening (21); an operating portion (40) that protrudes from the main body portion (30) and extends outward from the opening portion (21); The operating unit (40) a pair of plate-like portions (44) extending in a protruding direction of the operating portion (40) and having an operating point (P) at which an external force for removing the cap (1) from the opening (21) is applied, and a connecting portion (43) extending in a direction intersecting the protruding direction and connecting the pair of plate-like portions (44) at a position closer to the protruding ends of the pair of plate-like portions (44) than the operating point (P), and configured so that when the external force is applied, the operating point (P) is elastically displaced to a position where it overlaps the connecting portion (43) in the protruding direction; Cap(1).

[0033] According to the cap having the configuration [1] above, the cap's main body is fitted into the opening of the target, thereby sealing the opening. This allows the cap's inherent functions (e.g., dustproofness, waterproofness, etc.) to be realized. Furthermore, when the cap is fitted into the opening, a user can apply an external force to the operation unit protruding from the cap's main body to separate the cap from the opening. More specifically, when an external force is applied so as to sandwich the pair of plate-shaped portions of the operation unit in the thickness direction (e.g., when the user pinches the pair of plate-shaped portions with their fingers), the operation points of the plate-shaped portions elastically displace to a position where they overlap with the connecting portion connecting the plate-shaped portions in the protruding direction of the operation unit. In this state, when an external force is applied to the operation unit in a direction away from the opening (e.g., when the user tries to pull the cap out of the opening while pinching the pair of plate-shaped portions with their fingers), the external force acts not only on the plate-shaped portions but also on the connecting portion (e.g., the user's fingers get caught on the connecting portion). This makes it easier for the user to apply an external force to the operation unit. Therefore, the user can easily separate the cap from the opening. Therefore, the cap of this configuration can be easily separated from the opening to which it is attached while still maintaining its original function as a cap.

[0034] [2] In the cap (1) described in [1] above, The connecting portion (43) is The protruding end is disposed between the base ends of the pair of plate-like portions (44). Cap(1).

[0035] According to the cap having the configuration [2] above, the connecting portion is provided between the protruding end and the base end of the pair of plate-shaped portions. This allows the connecting portion to be provided in a position where the user can easily apply an external force for separation, depending on the positional relationship with the components around the cap (for example, the opening and closing lid that covers the area where the charging inlet is provided), the size of the cap, the length of the operating portion, and other specifications. This improves the workability of separating the caps.

[0036] [3] In the cap (1) described in [1] above, The main body (30) has a plate-shaped support (31) to which the operating part (40) is connected, The plate thickness (t1) of the pair of plate-shaped portions (44) is thinner than the plate thickness (t3) of the support portion (31). Cap(1).

[0037] According to the cap having the configuration [3] above, the thickness of the pair of plate-shaped parts is thinner than the thickness of the support part of the cap. This prevents the support part from being too thin, thereby maintaining the original function of the cap, while the thin thickness of the pair of plate-shaped parts allows the plate-shaped parts to be easily deformed by external force. This improves the workability of the operation of separating the cap.

[0038] [4] The cap (1) according to any one of [1] to [3] above, and an attachment object (2) having an opening (21) to which the cap (1) is attached. Capped unit (3).

[0039] According to the capped unit having the configuration [4] above, the cap's main body is fitted into the opening of the target, thereby sealing the opening. This allows the cap's inherent functions (e.g., dustproofness, waterproofness, etc.) to be realized. Furthermore, when the cap is fitted into the opening, the user can apply an external force to the operation unit protruding from the cap's main body to separate the cap from the opening. More specifically, when an external force is applied to sandwich the pair of plate-shaped portions of the operation unit in the thickness direction (e.g., when the user pinches the pair of plate-shaped portions with their fingers), the operation points of the plate-shaped portions elastically displace to a position where they overlap with the connecting portion connecting the plate-shaped portions in the protruding direction of the operation unit. In this state, when an external force is applied to the operation unit in a direction away from the opening (e.g., when the user tries to pull the cap out of the opening while pinching the pair of plate-shaped portions with their fingers), the external force acts not only on the plate-shaped portions but also on the connecting portion (e.g., the user's fingers get caught on the connecting portion). This makes it easier for the user to apply an external force to the operation unit. Therefore, the user can easily separate the cap from the opening. Therefore, the capped unit of this configuration allows the cap to be properly separated from the opening to which it is attached. [Explanation of symbols]
