Description

[Technical Field]

[0001] The present invention relates to a connector unit. [Background technology]

[0002] Patent Document 1 describes an in-vehicle connector in which a plug insertion opening is formed in a front panel provided at the end of a main body housing, and which is equipped with upper and lower shutter plates for opening and closing this plug insertion opening.

[0003] In the connector of Patent Document 1, when a plug is not inserted, the plug insertion opening is kept closed by the upper and lower shutter plates. In contrast, when a plug is inserted, the upper and lower shutter plates are displaced to open the plug insertion opening and allow the plug to be inserted. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-195455 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the configuration of Patent Document 1, in which a pair of shutter plates arranged near the plug insertion opening are displaced by the pressure of inserting the plug to open the plug insertion opening, there was a concern that dust and water droplets would enter the inside of the connector.

[0006] In particular, in a configuration in which the shutter plate faces upward, it is possible that dust and water droplets will adhere to the outer wall surface of the shutter plate when it is closed, and it is conceivable that this dust and water droplets will enter the inside of the connector when the plug is inserted, so there is room for improvement.

[0007] For these reasons, there is a demand for a connector unit that can adequately prevent dust and water droplets from entering the inside of the connector. [Means for solving the problem]

[0008] A characteristic configuration of the connector unit according to the present invention includes a board on which a connector is mounted, a housing that houses the board, a lid that is attached to the housing and is switchable between a closed position that covers an insertion hole in the housing through which a plug to be inserted into the connector passes and an open position that opens the insertion hole, and a hinge portion that is disposed across the housing and the lid and that switchably connects the housing and the lid, the housing having an end wall in which the insertion hole is formed, the hinge portion being erected on an outer wall surface of the end wall, The housing has a hinge block having a first shaft hole formed therein that is parallel to the outer wall surface of the end wall, a bearing portion having a second shaft hole formed in the lid body, and a hinge shaft that is housed from the first shaft hole to the second shaft hole and connects the housing and the lid body, and the lid body has an abutment portion that abuts against an abutment surface of the hinge block that faces the outer wall surface when the lid body is switched from the closed position to the open position by rotating relative to the housing around the hinge shaft.

[0009] According to this configuration, by rotating the lid body relative to the housing using the hinge portion to a closed position, it is possible to cover the insertion hole in the end wall of the housing. In contrast, by rotating the lid body to an open position, the abutment portion abuts against the abutment surface of the hinge block that faces the outer wall, determining the limit of the open side of the lid body. This opens the insertion hole, facilitating insertion and removal of a plug into and from the connector. It is also possible to configure the hinge block so that the first shaft hole is located near the end wall. This configuration ultimately enables the miniaturization of the connector unit. Furthermore, simply forming the abutment portion on the side of the lid body makes it possible to determine the limit of the open side of the lid body, preventing damage to the lid and / or the housing due to excessive rotation of the lid. Therefore, a connector unit is configured that can appropriately prevent dust and water droplets from entering the inside of the connector.

[0010] In addition to the above configuration, it is preferable that the cover body has a hinge recess in an area along the outer periphery into which the hinge block fits, the second shaft hole is coaxial with the first shaft hole when the hinge block is fitted into the hinge recess, and the abutment portion is formed in the hinge recess.

[0011] By fitting the hinge block formed on the end wall into the hinge recess formed on the lid body, the protruding length of the lid body from the end wall can be shortened, thereby preventing the connector unit from becoming larger.

[0012] In addition to the above configuration, it is preferable that the abutment length of the abutment portion along the longitudinal direction of the hinge shaft is equal to or slightly shorter than the recess length of the hinge recess along the longitudinal direction of the hinge shaft.

[0013] This allows the length of the contact portion to be made as long as possible, ensuring contact between the contact portion and the hinge block and suppressing deformation and wear that may occur when contact is repeated, allowing the lid body to maintain its position at its open limit for a long period of time.

[0014] In addition to the above configuration, it is preferable that the bearing portions are formed on both sides of the hinge block in a direction along the longitudinal direction of the hinge shaft.

[0015] This results in a configuration in which the lid body is supported at two points sandwiching the hinge block, making it possible to rotate the lid body in a stable state and improving the durability of the hinge portion.

[0016] In addition to the above configuration, it is preferable that the hinge block has a block end face in which the first shaft hole is formed, the bearing portion has a lid end face in which the second shaft hole is formed at a position opposite the block end face, a protruding engagement portion protruding from the block end face is formed in a central region of the block end face including the first shaft hole, and a groove-shaped portion into which the protruding engagement portion can be introduced is formed in the central region of the lid end face including the second shaft hole.

[0017] According to this, when supporting the lid body on the housing, the protruding engagement portion formed on the end of the block is fitted into the groove-shaped portion on the end face of the lid body, and by moving the protruding engagement portion along the groove-shaped portion, the first shaft hole and the second shaft hole reach a position where they are coaxial, making it easy to insert the support shaft.

[0018] In addition to the above configuration, it is preferable that the groove-shaped portion be formed in an area extending radially from the opening / closing axis, which is the center of opening and closing of the lid body when the lid body is in the closed position, toward the end wall.

[0019] With this, when supporting the lid body on the housing, the lid body can be set in the same position as the closed position and the entire lid body can be moved toward the end wall, making it possible to position the first axial hole and the second axial hole coaxially, making it easy to attach the lid body to the housing.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A connector unit according to an embodiment of the present invention will now be described with reference to the accompanying drawings. The present invention is not limited to the following embodiments, and various modifications are possible without departing from the spirit and scope of the present invention.

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Basic configuration] As shown in Figures 1 to 3, the connector unit A has a resin housing 10 that houses a board 4 on which each of the first connector 1, the second connector 2, and the power supply circuit 3 is mounted, and a resin lid body 20 that is supported on an end wall 11 of the housing 10 via a hinge portion H so that it can be opened and closed freely.

[0023] Furthermore, the power supply circuit 3 does not necessarily need to have a power source such as a battery or cell on the substrate 4, and may be configured as a circuit that simply converts voltage using power supplied from an external source, or the power supply circuit 3 can be omitted.

[0024] 1, 2, 6, and 7, the cover 20 is connected to the housing 10 by a hinge H so as to be switchable between a closed position CL and an open position OP around an opening / closing axis P. The closed position CL is a state in which the cover 20 covers an insertion hole 11a (described later) and at least a portion of the outer edge 21 faces and abuts against or is closest to the end wall 11. The open position OP is a state in which the cover 20 has rotated from the closed position CL to its rotation limit around the hinge axis.

[0025] Connector unit A uses a first connector 1 that complies with the USB (abbreviation for Universal Serial Bus, registered trademark) standard, and is intended for placement inside the door of a vehicle such as an automobile, or on a panel inside the cabin. Connector unit A is used as a charging terminal that supplies power from first connector 1 to portable devices such as smartphones and tablets.

[0026] The connector unit A can be used in any position, such as with the first connector 1 facing sideways or diagonally upward. In the following explanation, the positional relationship of each part of the connector unit A will be explained based on the position where the first connector 1 is facing upward as shown in Figures 1 and 2.

[0027] 1 and 2, in order to explain the positional relationship of each part of the connector unit A, the direction along the left and right of the connector unit A is referred to as the lateral direction X, the direction along the front and back is referred to as the front-back direction Y, and the direction along the top and bottom is referred to as the up-down direction Z. Furthermore, hereinafter, the side on which the housing 10 is arranged with respect to the cover 20 along the up-down direction Z will be referred to as the lower side or the lower direction, and the side on which the cover 20 is arranged with respect to the housing 10 will be referred to as the upper side or the upper direction.

[0028] As shown in Fig. 3, the board 4 is housed in a housing 10 together with a metal shield 5. The board 4 has a first connector 1 at its upper end and a second connector 2 at its lower end. Power is supplied to the second connector 2 from the vehicle's power supply, and the voltage and other parameters of this power are adjusted by the power supply circuit 3 before being supplied to the first connector 1.

[0029] [Case] As shown in FIGS. 1 to 4, the housing 10 is made up of a main housing 12 formed by combining a pair of side walls 12a, and a sub-housing 13 fitted onto the top end of the main housing 12.

[0030] The side wall 12a has a channel-shaped (U-shaped) cross section in plan view (viewed in the direction along the vertical direction Z). To connect the pair of side walls 12a, one side wall 12a has engaging protrusions 12c on the left and right outer walls (lateral direction X). The other side wall 12a has arms 12d that can engage with the engaging protrusions 12c.

[0031] With this configuration, by bringing the pair of side walls 12a closer together, the pair of arm bodies 12d engage with the corresponding engaging protrusions 12c, and the pair of side walls 12a reach a connected state. As a result of this connection, a cylindrical main housing 12 with a bottom is formed. The main housing 12 also has an insertion opening 12t in the bottom wall that opens to the bottom of the second connector 2. Note that the method of connecting the pair of side walls 12a is not limited to the engagement of the engaging protrusions 12c and the arm bodies 12d, and other methods, such as using screws, may also be used.

[0032] As shown in Figures 3 and 4, the sub-housing 13 has a cylindrical structure with a rectangular cross section that opens in the vertical direction Z, and an end wall 11 is connected to close the upper opening. The end wall 11 may be rectangular in size larger than the outer shape of the sub-housing 13 in a plan view, or may be the same size, and is arranged in a position that covers the upper end of the sub-housing 13. The end wall 11 has the above-mentioned insertion hole 11a formed therein. This insertion hole 11a is an opening through which a plug (not shown) that is connected to the first connector 1 is inserted. The sub-housing 13 is fixed in a fitted state to the upper part of the main housing 12.

[0033] Sub-housing 13 may have mounting portion 13a. When assembling connector unit A to the installation location, mounting portion 13a may be elastically deformed to allow connector unit A to move to a predetermined position at the installation location, and may be configured to return to its original shape after connector unit A has moved to the predetermined position, thereby fixing connector unit A to the installation location.

[0034] [Hinge] 3 to 5, the lid 20 is generally rectangular plate-shaped, and when the lid 20 is in the closed position CL, the outer edge 21 extends upward from the end wall 11 so that the lower surface of the central portion is recessed upward. A hinge recess 22 is formed in the lid 20 by cutting out a portion of one of the outer edge portions 21 on each of the four sides. In particular, the length of the hinge recess 22 in the lateral direction X is referred to as the recess length M.

[0035] In the cover 20, the region adjacent to the hinge recess 22 that faces the block end surface 15c of the hinge block 15 (see FIGS. 3 and 5) is referred to as a bearing portion 21a.

[0036] 3 to 5, the hinge portion H has a hinge block 15 formed integrally with the end wall 11, the pair of bearing portions 21a, and a pair of hinge shafts 26. The hinge portion H is a general term for the portion that supports the cover 20 relative to the end wall 11 so that it can be opened and closed freely about the opening and closing axis P. The hinge block 15 is formed to a size that allows it to be fitted into the hinge recess 22.

[0037] The hinge block 15 is erected on the outer wall surface 11S of the end wall 11 at a position separated from the insertion hole 11a. The hinge block 15 is formed with a length of a set value L along the lateral direction X. The recess length M of the hinge recess 22 in the direction along the opening / closing axis P is set to be equal to the set value L or to a value slightly longer than the set value L (0.1 mm to several mm).

[0038] 6 and 7, when viewed in a direction along the opening / closing axis P (viewed in a direction along the first shaft hole 15d), the hinge block 15 is obliquely oriented so that the protruding end is more distant from the outer wall surface 11S of the end wall 11 the farther it is from the insertion hole 11a, and a circumferential surface 15a is formed at the protruding end, the center of which is the opening / closing axis P. The hinge block 15 has an abutment surface 15b on the outer surface of the circumferential surface 15a at a position facing the outer wall surface 11S. When the lid 20 is in the open position OP, an abutment portion 22r (described later) abuts against the abutment surface 15b.

[0039] 3 and 5, block end faces 15c perpendicular to the opening / closing axis P are formed at end positions of the circumferential surface 15a in the lateral direction X. The hinge block 15 may have first shaft holes 15d formed coaxially with the opening / closing axis P so as to penetrate the block end faces 15c at both ends, or the first shaft holes 15d that open to each block end face 15c, are coaxial with the opening / closing axis P, and have a bottom formed in each block end face 15c.

[0040] 5, the cover 20 has cover end faces 22a formed on end faces (surfaces exposed to the hinge recess 22) of a pair of opposing bearing portions 21a. A second shaft hole 22b, which is coaxial with the opening / closing axis P, is formed in this cover end face 22a and penetrates the cover 20 from the cover end face 22a in a direction parallel to the lateral direction X. A pair of second shaft holes 22b are formed at positions sandwiching the hinge recess 22.

[0041] With this configuration, by inserting the hinge shaft 26 into the region extending from the second shaft hole 22b to the first shaft hole 15d with the hinge block 15 fitted in the hinge recess 22, the cover 20 can be rotated about the opening / closing axis P relative to the end wall 11. The hinge shaft 26 may be manufactured by processing a metal plate into a cylindrical shaft having a C-shaped cross section, or may be a cylindrical rod extending in the lateral direction X, or may have a structure that can be contracted in diameter by elastic deformation toward the opening / closing axis P, or may be manufactured by molding an elastic material into a rod shape. To achieve a structure that can be contracted in diameter by elastic deformation toward the opening / closing axis P, a metal plate may be processed into a cylindrical shape with a gap, and when a load is applied in the axial direction, the gap may be elastically deformed to narrow, thereby contracting in diameter; there are no limitations on the material or processing method.

[0042] There may also be two hinge shafts 26. In this embodiment, one hinge shaft 26 is housed in each of the second shaft holes 22b on one side in the lateral direction X and the other side in the lateral direction X, and the first shaft hole 15d is also separated by a bottom wall on one side in the lateral direction X and the other side in the lateral direction X.

[0043] [Hinge: Rotation limit] As described above, the lid body 20 is configured to be freely switchable between the closed position CL (rotation limit on the closed side) shown in Figures 1 and 7 and the open position OP (rotation limit on the open side) shown in Figures 2 and 6.

[0044] The lid 20 has a sleeve portion 23 that is annular in plan view so as to abut against the area surrounding the insertion hole 11a in the closed position CL. When the sleeve portion 23 abuts against the outer wall surface 11S of the end wall 11 in the closed position CL, the outer edge portion 21 of the lid 20 may abut against the outer wall surface 11S of the end wall 11 or may be slightly spaced apart from the outer wall surface 11S of the end wall 11. Note that the sleeve portion 23 can be omitted, and when the sleeve portion 23 is omitted, at least a portion of the outer edge portion 21 of the lid 20 may abut against the end wall 11S in the closed position CL.

[0045] 4 and 7, the outer edge 21 of the cover 20 is provided with a plate portion 24 on the outer edge opposite the hinge recess 22 in a plan view. This plate portion 24 is formed in a direction that protrudes downward toward the end wall 11 when the cover 20 is in the closed position CL, and a latch protrusion 24a is formed on the protruding end. In addition, the end wall 11 is formed with a latch hole 11b that engages with the latch protrusion 24a when the cover 20 reaches the closed position CL shown in FIG.

[0046] With this structure, when the lid 20 is rotated to the closed position CL, the latch protrusion 24a engages with the outer edge of the latch hole 11b, as shown in Fig. 7, causing the lid 20 to reach its rotation limit on the closing side, preventing displacement of the lid 20 in the opening direction. In particular, with the lid 20 maintained in the closed position, the connector unit A maintains a state in which the protruding end of the sleeve 23 is in close contact with the outer periphery of the insertion hole 11a on the opposing wall surface of the end wall 11. Note that a so-called half-lock structure may be used in which, when the lid 20 is rotated by a finger or the like in the closed position CL, the plate 24 is slightly elastically displaced toward the sleeve 23, disengaging the latch protrusion 24a from the latch hole 11b.

[0047] As shown in Figures 5 and 6, in the hinge portion H, the lid body 20 is formed with an abutment portion 22r that determines the limit of the opening side of the lid body 20 by abutting against the underside of the circumferential surface 15a of the hinge block 15 when the lid body 20 is rotated to the open position OP.

[0048] The rotation limit on the open side of the lid 20 is called the open position OP, and when the lid 20 is in the open position OP, the end wall 11 and the outer wall portion of the lid 20 are parallel to each other. In the open position OP, the abutment portion 22r abuts against the abutment surface 15b of the hinge block 15, and the angle from the closed position CL is approximately 180 degrees.

[0049] The abutment portion 22r is formed integrally with the lid 20 at the opening edge of the hinge recess 22, and may be formed on the hinge block 15 so as to protrude toward the opening / closing axis P. The abutment portion 22r is formed so that the abutment length (length of the abutment portion) in the direction along the opening / closing axis P is equal to the recess length M described above or slightly shorter than the recess length M. Furthermore, when the lid 20 is in the closed position CL, the abutment portion 22r is disposed in a position that is covered by the lid 20 in a plan view. In this case, the abutment portion 22r is not visible in a plan view.

[0050] [Hinge part: assembly auxiliary structure] 3 and 5, the hinge block 15 is formed with annular protruding engagement portions 15f that protrude outward (in the direction along the lateral direction X) from the central region of each of a pair of block end faces 15c along the opening / closing axis P. The pair of protruding engagement portions 15f are arranged coaxially with the opening / closing axis P, and a first shaft hole 15d is formed coaxially with the opening / closing axis P and parallel to the lateral direction X.

[0051] That is, the protruding engagement portion 15f is formed so that the portion surrounding the first shaft hole 15d protrudes from the block end surface 15c.

[0052] As shown in Fig. 5, a groove 22g into which the protruding engagement portion 15f can be inserted is formed in a central region of the lid end surface 22a, which is formed on the end surfaces of the pair of bearing portions 21a of the lid 20, including the second shaft hole 22b. This groove 22g is formed from the outside of the lid end surface 22a to the region surrounding the second shaft hole 22b. In the closed position CL, the lower side of the groove 22g is open radially outward from the second shaft hole 22b (see Fig. 7). In addition, in the closed position CL, the inner surface of the upper side of the groove 22g is semicircular and coaxial with the second shaft hole 22b, and the inner diameter of the arc is approximately the same as the outer diameter of the protruding engagement portion 15f.

[0053] With this configuration, when connecting the lid 20 to the hinge block 15, the pair of protruding engagement portions 15f on the block end surface 15c of the hinge block 15 are inserted into the corresponding groove-shaped portions 22g of the pair of lid end surfaces 22a from the open side. In this inserted state, the lid 20 and the housing 10 are moved relative to each other so that the semicircular arc-shaped portions of the first shaft hole 15d and the second shaft hole 22b approach (abut) each other, thereby setting the first shaft hole 15d and the second shaft hole 22b coaxially.

[0054] By performing this relative movement and inserting hinge shaft 26 from each of the two second shaft holes 22b opening in the outer wall surface of lid body 20 until it reaches first shaft hole 15d, hinge section H is completed, and lid body 20 is rotatably connected to housing 10 (end wall 11). When first shaft hole 15d penetrates in lateral direction X, there may be only one hinge shaft 26, and in this case, hinge section H is completed by inserting hinge shaft 26 from one second shaft hole 22b through first shaft hole 15d until it reaches the other second shaft hole 22b.

[0055] [Effects of the embodiment] In this way, when the lid body 20 of the connector unit A is rotated from the closed position CL toward the open position OP, the abutment portion 22r of the lid body 20 abuts against the hinge block 15, and the lid body 20 reaches the open limit, i.e., the open position OP. In this open position OP, the lid body 20 rotates approximately 180 degrees from the closed position CL, so that it opens widely, allowing easy insertion and removal of a plug into and from the first connector 1.

[0056] Furthermore, even if the lid body 20 of the connector unit A is rotated to alternate between the closed position CL and the open position OL, the lid body 20 and the sub-housing 13 can be prevented from having scratches or wear marks due to contact on the visible exterior, which would impair the interior appearance.

[0057] Furthermore, the connector unit A has a groove portion 22g formed in a region extending radially from the opening / closing axis P, which is the center of opening and closing of the lid body 20 when the lid body 20 is in the closed position CL, toward the end wall 11. Therefore, when supporting the lid body 20 on the housing 10, the first axial hole 15d and the second axial hole 22b can be coaxially arranged by moving the entire lid body 20 toward the end wall 11 with the lid body 20 set in the same position as the closed position CL, and this makes it easy to attach the lid body 20 to the housing 10.

[0058] Furthermore, when the lid body 20 of the connector unit A is operated to the closed position CL, the latch protrusion 24a of the plate portion 24 engages with the latch hole 11b of the end wall 11, making it possible to maintain the lid body 20 in the closed position CL. In this closed position CL, the outer edge portion 21 and the sleeve portion 23 reach a position where they double-cover the insertion hole 11a of the end wall 11, and the protruding end of the sleeve portion 23 abuts against the end wall 11, and the outer edge portion 21 and the sleeve portion 23 prevent dust and water from entering the insertion hole 11a.

[0059] Furthermore, when assembling the hinge section H of the connector unit A, first, the pair of protruding engagement sections 15f of the hinge block 15 are inserted into the corresponding groove sections 22g in the cover end surface 22a of the cover 20. Next, in this inserted state, the cover 20 and the housing 10 are moved relative to each other so that the first shaft hole 15d and the second shaft hole 22b approach each other, thereby setting the first shaft hole 15d and the second shaft hole 22b coaxially. In this set state, the hinge shafts 26 are inserted through the two second shaft holes 22b opening in the outer wall surface of the cover 20 until they reach the first shaft hole 15d, thereby completing the hinge section H.

[0060] Furthermore, the length of the abutment portion 22r in the direction along the opening / closing axis P is equal to or slightly shorter than the set value L, which ensures that the abutment portion 22r and the hinge block 15 abut against each other, suppressing deformation and wear that may occur when the abutment is repeated and maintaining the lid 20 at a set open limit. If the abutment portion 22r is configured to protrude toward the opening / closing axis P when the lid 20 is in the closed position CL, the thick-walled structure caused by the protrusion reduces the risk of damage such as cracks due to impact from the abutment, and also reduces the reduction in strength due to short shots and welds during molding.

[0061] [Another embodiment] The present invention may be configured as follows in addition to the above-described embodiments (common numbers and symbols are used to designate components having the same functions as those in the embodiments).

[0062] (a) The number of first connectors 1 is not limited to one, and multiple first connectors 1 may be provided on the board 4, and the end wall 11 may be configured to have insertion holes 11a corresponding to the number of connectors. When multiple insertion holes 11a are provided, the cover 20 may be one or multiple sleeve portions 23 may be provided corresponding to the number of insertion holes 11a. In addition, small switches and lamps indicating the operating status of the device may be provided in an exposed state on the outer wall surface 11S of the end wall 11. Even with this configuration, the switches and lamps can be covered by setting the cover 20 to the closed position CL.

[0063] (b) In the embodiment, a groove-shaped portion 22g is formed on the block end face 15c of the hinge block 15. However, conversely, it is also possible to form a protruding engagement portion on the bearing portion of the cover body 20 and form a groove-shaped portion 22g on the block end face 15c of the hinge block 15.

[0064] Even with this configuration, when the cover body 20 is set on the hinge block 15, the first shaft hole 15d and the second shaft hole 22b can be coaxially arranged in a short time.

[0065] (c) The structure of the housing 10 is not limited to the main housing 12 and the sub-housing 13 as described in the embodiment, but may be a single housing or may be three or more housings. It is also possible to use a housing 10 that does not have an end wall 11 as shown in the embodiment.

[0066] Furthermore, the configurations disclosed in the above embodiments (including other embodiments, the same applies below) can be applied in combination with configurations disclosed in other embodiments, as long as no contradictions arise. Furthermore, the embodiments disclosed in this specification are examples, and the embodiments of the present invention are not limited to these, and can be modified as appropriate within the scope that does not deviate from the purpose of the present invention.
