Means for Solving the Problems

[0008] According to this disclosure, a good cover and housing can be provided. [Brief explanation of the drawing]

[0009] [Figure 1] Figure 1 is a perspective view of the housing. [Figure 2] Figure 2 is a cross-sectional view along the line II-II in Figure 1. [Figure 3] Figure 3 is an exploded perspective view of the housing. [Figure 4] Figure 4 shows the state in which the tip of the hook is positioned in the storage area. [Figure 5] Figure 5 shows the state in which the first and second partial hooks are in contact with the back surface of the plate-like portion. [Figure 6] Figure 6 shows the state in which the hook with the third connection point severed is pulled out of the housing. [Modes for carrying out the invention]

[0010] When the connector is not in use, the opening of the housing that houses the connector is closed by a lid provided on the cover. Closing the opening with the lid prevents dust and other debris from entering the housing. The cover is equipped with a hook. This hook is inserted through the insertion hole and also hooks the lid onto the housing member. As a result, when the user pulls the lid, the hook catches on the housing member, preventing the lid from detaching from the housing member. However, if the user pulls the lid with a force exceeding the tensile strength of the hook, the hook may break. There is a concern that a part of the broken hook may remain inside the housing. According to the embodiment shown below, it is possible to prevent the hook from remaining inside the housing and to easily remove the broken hook from the housing.

[0011] As shown in Figure 1, the housing 10 has a housing member 12 and a cover 14. As shown in Figure 2, in this embodiment, the housing 10 is mounted in a vehicle (not shown) as part of an electrical component 16. Specifically, the electrical component 16 is an audio system. The electrical component 16 is located, for example, on the instrument panel of the vehicle.

[0012] The electrical component 16 comprises a housing 18. The housing 18 has a housing opening 19. The housing opening 19 communicates with the interior of the housing 18. The interior space of the housing 18 adjacent to the housing opening 19 is configured as a housing section 24 for housing the connector 22.

[0013] The housing 10 is provided in the housing opening 19. More specifically, the housing member 12 is provided in the housing opening 19. The housing 10 is positioned to close the housing opening 19. Therefore, the housing section 24 is isolated from the outside of the casing 18 by the housing 10 being provided in the housing opening 19.

[0014] As shown in Figure 3, the housing member 12 has a plate-shaped portion 26, two engaging portions 28, an outer peripheral wall 30, and a connector mounting portion 32 (see Figure 2).

[0015] As shown in Figure 3, the plate-like portion 26 is a rectangular flat plate. As shown in Figure 2, the plate-like portion 26 is positioned inside the housing 18 so as to face the housing opening 19. The surface 26a of the plate-like portion 26 is exposed to the outside of the housing 18 through the housing opening 19. The back surface 26b of the plate-like portion 26 is the surface opposite to the surface 26a.

[0016] As shown in Figure 3, in the following explanation, the direction perpendicular to the surface 26a and back surface 26b (see Figure 2) of the plate-like portion 26 will be referred to as the Z direction (first direction). The longitudinal direction of the plate-like portion 26, which is perpendicular to the Z direction, will be referred to as the Y direction (second direction). The direction perpendicular to both the Z and Y directions will be referred to as the X direction. The X direction is the short-side direction of the plate-like portion 26, which is perpendicular to the Z direction.

[0017] As shown in FIG. 2, a housing opening 34 and an insertion hole 36 are formed in the plate-like portion 26.

[0018] As shown in FIG. 3, the housing opening 34 is formed in the central portion of the plate-like portion 26. The housing opening 34 is a rectangular opening formed along the Z direction. The housing opening 34 can communicate the accommodation opening 19 (see FIG. 2) and the accommodation portion 24. The housing opening 34 is an elongated hole whose dimension in the Y direction is larger than the dimension in the X direction.

[0019] The insertion hole 36 is formed in the plate-like portion 26 at a distance from the housing opening 34 in the X direction. The insertion hole 36 is a rectangular opening formed along the Z direction. The insertion hole 36 can communicate the accommodation opening 19 (see FIG. 2) and the accommodation portion 24. The insertion hole 36 is an elongated hole whose dimension in the Y direction is larger than the dimension in the X direction.

[0020] As shown in FIG. 2, the connector attachment portion 32 is a cylindrical portion that protrudes along the Z direction from the back surface 26b of the plate-like portion 26. The connector attachment portion 32 is formed coaxially with the housing opening 34. The inner peripheral surface of the connector attachment portion 32 is flush with the edge of the housing opening 34.

[0021] The connector 22 is a USB connector. The connector 22 is supported by the housing member 12 when the tip side of the connector 22 is inserted inside the connector attachment portion 32.

[0022] As shown in FIG. 4, the two engaging portions 28 protrude along the Z direction from the back surface 26b of the plate-like portion 26. The two engaging portions 28 are provided at intervals in the Y direction with the connector attachment portion 32 (see FIG. 2) interposed therebetween. The two engaging portions 28 engage with two locking portions (not shown) provided inside the housing 18. When the two engaging portions 28 engage with the two locking portions, the housing member 12 is supported inside the housing 18.

[0023] As shown in Figure 3, the outer peripheral wall 30 protrudes along the Z direction from the outer peripheral portion of the surface 26a of the plate-like portion 26. The outer peripheral wall 30 has a first outer peripheral wall portion 30a and a second outer peripheral wall portion 30b.

[0024] The first outer peripheral wall portion 30a protrudes from the outer peripheral portion of the surface 26a of the plate-like portion 26 along the Z direction. Multiple engagement holes 38 are formed in the first outer peripheral wall portion 30a at intervals. In Figure 3, four engagement holes 38 are formed. A bulge portion 40 is formed on the inner peripheral surface of the first outer peripheral wall portion 30a, bulging inward from the first outer peripheral wall portion 30a. A recess 42 for accommodating a hinge 46, which will be described later, is formed in the first outer peripheral wall portion 30a.

[0025] The second outer peripheral wall portion 30b protrudes along the Z direction from the protruding end of the first outer peripheral wall portion 30a. As shown in Figure 2, the second outer peripheral wall portion 30b protrudes along the Z direction so as to expand outward from the first outer peripheral wall portion 30a. The protruding end of the second outer peripheral wall portion 30b abuts against the edge of the receiving opening 19.

[0026] As shown in Figure 3, the cover 14 comprises a lid portion 44, a hinge 46, a hook 48, and a pair of leaf spring portions 49. The cover 14 is made of a flexible material. The material of the cover 14 is polypropylene. The lid portion 44, the hinge 46, the hook 48, and the leaf spring portions 49 are integrally molded.

[0027] The properties, materials, and structure of the cover 14 are not limited to those described above. The material of the cover 14 may be rubber. Only a portion of the cover 14 may be made of a flexible material. At least the hook 48 is made of a flexible material.

[0028] The lid portion 44 is a rectangular plate-like portion. The lid portion 44 is positioned on the surface 26a of the plate-like portion 26 of the housing member 12 inside the first outer peripheral wall portion 30a, thereby closing the housing opening 34.

[0029] The outer circumference of the cover portion 44 is provided with four engaging claws 52. The four engaging claws 52 can engage with four engaging holes 38.

[0030] A gripping portion 50 is formed on the outer periphery of the lid portion 44. The gripping portion 50 protrudes from the outer periphery of the lid portion 44 in the thickness direction of the lid portion 44 (the Z direction in Figure 3). As shown in Figure 2, when the lid portion 44 is placed on the surface 26a of the plate-like portion 26, the gripping portion 50 faces the bulging portion 40 in the Z direction. A gap is formed between the gripping portion 50 and the bulging portion 40, into which the user can insert their finger. The user can open the lid portion 44 by inserting their finger into the gap and lifting the gripping portion 50 relative to the surface 26a of the plate-like portion 26.

[0031] As shown in Figure 3, the hinge 46 is connected to the lid portion 44. More specifically, the hinge 46 is located on the outer circumference of the lid portion 44, opposite to the grip portion 50. As shown in Figure 2, when the lid portion 44 is positioned on the surface 26a of the plate-shaped portion 26, the hinge 46 is positioned in the recess 42 so as to face the insertion hole 36 in the Z direction. The hinge 46 rotatably supports the lid portion 44.

[0032] As shown in Figure 3, the pair of leaf spring sections 49 are connected to the hinge 46 with a gap in the Y direction. The pair of leaf spring sections 49 are located on both sides of the hook 48. As shown in Figure 4, when the lid section 44 is positioned on the surface 26a of the plate section 26, the pair of leaf spring sections 49 are inserted through the insertion hole 36. The leaf spring sections 49 are supported by the inner wall of the insertion hole 36.

[0033] The hook 48 is a component molded in the shape of an arrow as a whole. The hook 48 is connected to the hinge 46. More specifically, the base 48a of the hook 48 is connected to the hinge 46. The hook 48 is connected to the lid 44 via the hinge 46. The hook 48 extends from the hinge 46 along the Z direction.

[0034] The hook 48 is inserted through the insertion hole 36. As shown in Figure 5, a portion of the hook 48 contacts the back surface 26b of the plate-shaped portion 26, thereby hooking the lid portion 44 onto the housing member 12.

[0035] More specifically, the hook 48 comprises a first partial hook 54a, a second partial hook 54b, a first connecting portion 56a, a second connecting portion 56b, and a third connecting portion 56c.

[0036] The base ends of the first connecting portion 56a, the second connecting portion 56b, and the third connecting portion 56c are connected to the hinge 46. The portions of the first connecting portion 56a, the second connecting portion 56b, and the third connecting portion 56c that are connected to the hinge 46 constitute the base portion 48a of the hook 48.

[0037] The first connecting portion 56a, the second connecting portion 56b, and the third connecting portion 56c extend from the hinge 46 along the direction from the base 48a to the tip 48b of the hook 48 (the Z direction in Figure 5). The first connecting portion 56a, the second connecting portion 56b, and the third connecting portion 56c extend parallel to each other in the Y direction. The third connecting portion 56c is located between the first connecting portion 56a and the second connecting portion 56b. Therefore, the first connecting portion 56a and the second connecting portion 56b are located with the third connecting portion 56c in between.

[0038] The first portion hook 54a is connected to the hinge 46 via the first connecting portion 56a. The first portion hook 54a is connected to the lid portion 44 via the first connecting portion 56a and the hinge 46.

[0039] The second portion hook 54b is connected to the hinge 46 via the second connecting portion 56b. The second portion hook 54b is connected to the lid portion 44 via the second connecting portion 56b and the hinge 46.

[0040] Both the first hook 54a and the second hook 54b are connected to the hinge 46 via the third connecting portion 56c. Both the first hook 54a and the second hook 54b are connected to the lid portion 44 via the third connecting portion 56c and the hinge 46.

[0041] Thus, the first portion hook 54a is connected to the hinge 46 by the first connecting portion 56a and the third connecting portion 56c. The second portion hook 54b is connected to the hinge 46 by the second connecting portion 56b and the third connecting portion 56c. A portion of the first portion hook 54a and a portion of the second portion hook 54b constitute the tip portion 48b of the hook 48.

[0042] The first part hook 54a and the second part hook 54b protrude in different directions from each other. The first part hook 54a and the second part hook 54b are each formed in a U shape.

[0043] More specifically, the first part hook 54a includes a first linear portion 62a and a second linear portion 64a. The first linear portion 62a extends linearly from the tip side of the first connecting portion 56a. The second linear portion 64a extends linearly from the tip side of the third connecting portion 56c, following the first linear portion 62a. The tip of the first linear portion 62a and the tip of the second linear portion 64a are connected to each other. The connection point between the tip of the first linear portion 62a and the tip of the second linear portion 64a constitutes the intermediate portion 58a of the first part hook 54a.

[0044] Therefore, the first hook portion 54a has a shape that is folded back at the intermediate portion 58a. The base end of the first linear portion 62a is one end of the first hook portion 54a and is connected to the tip side of the first connecting portion 56a. The base end of the second linear portion 64a is the other end of the first hook portion 54a and is connected to the tip side of the third connecting portion 56c.

[0045] Furthermore, the second part hook 54b includes a third linear portion 62b and a fourth linear portion 64b. The third linear portion 62b extends linearly from the tip side of the second connecting portion 56b. The fourth linear portion 64b extends linearly from the tip side of the third connecting portion 56c along the third linear portion 62b. The tip of the third linear portion 62b and the tip of the fourth linear portion 64b are connected to each other. The connection point between the tip of the third linear portion 62b and the tip of the fourth linear portion 64b constitutes the intermediate portion 58b of the second part hook 54b.

[0046] Therefore, the second hook portion 54b has a shape that is folded back at the intermediate portion 58b. The base end of the third linear portion 62b is one end of the second hook portion 54b and is connected to the tip side of the second connecting portion 56b. The base end of the fourth linear portion 64b is the other end of the second hook portion 54b and is connected to the tip side of the third connecting portion 56c.

[0047] As shown in Figure 3, the third connecting portion 56c is thinner than both the first connecting portion 56a and the second connecting portion 56b. Furthermore, the minimum cross-sectional area of ​​the third connecting portion 56c is smaller than both the minimum cross-sectional area of ​​the first connecting portion 56a and the minimum cross-sectional area of ​​the second connecting portion 56b. In Figure 4, the narrow portion 60 of the third connecting portion 56c that is close to the hinge 46 is formed as the portion that constitutes the minimum cross-sectional area of ​​the third connecting portion 56c. The tensile strength of the third connecting portion 56c is lower than both the tensile strength of the first connecting portion 56a and the tensile strength of the second connecting portion 56b.

[0048] As shown in Figure 4, when the narrow portion 60 of the third connecting portion 56c is not cut, the maximum dimension L1 of the hook 48 in the Y direction is greater than the maximum dimension L2 of the insertion hole 36 (L1 > L2). Note that the maximum dimension L1 is the distance in the Y direction between the tip of the intermediate portion 58a of the first portion hook 54a and the tip of the intermediate portion 58b of the second portion hook 54b.

[0049] Furthermore, as shown in Figure 6, when the third connecting portion 56c is cut off at the narrow portion 60 (see Figure 5), the maximum dimension L3 of the hook 48 in the Y direction may be less than or equal to the maximum dimension L2 of the insertion hole 36 (L2 > L3).

[0050] Next, we will explain the function of housing 10.

[0051] First, we will explain the case in which the cover 14 is attached to the housing member 12 located in the storage section 24.

[0052] As shown in Figure 3, when the worker inserts the hook 48 and the pair of leaf springs 49 into the insertion hole 36, the first portion hook 54a and the second portion hook 54b come into contact with the outer edge of the insertion hole 36. Because the hook 48 is flexible, when the worker pushes the hook 48 further into the insertion hole 36, the hook 48 bends due to the resistance force from the plate-like portion 26, causing the first portion hook 54a and the second portion hook 54b to move closer to each other. This allows the worker to insert the first portion hook 54a and the second portion hook 54b into the insertion hole 36. Once the first portion hook 54a and the second portion hook 54b have passed through the insertion hole 36, they are released from the resistance force of the plate-like portion 26 and return to their original state as shown in Figure 4. As a result, the first portion hook 54a and the second portion hook 54b are positioned on the back surface 26b side of the plate-like portion 26. Furthermore, the pair of leaf spring portions 49 abut against the inner wall of the insertion hole 36.

[0053] Next, as shown in Figure 1, the operator places the lid portion 44 on the surface 26a of the plate-shaped portion 26 of the housing member 12 (see Figure 3). At this time, the lid portion 44 is pushed in the X direction (towards the gripping portion 50) by the spring force of the leaf spring portion 49, causing the two engaging claws 52 on the gripping portion 50 side to engage with the two engaging holes 38. The gripping portion 50 is also positioned so as to face the bulging portion 40 (see Figure 2). Furthermore, the hinge 46 is positioned in the recess 42. With the lid portion 44 positioned on the surface 26a of the plate-shaped portion 26, the housing opening 34 is closed by the lid portion 44.

[0054] Next, we will describe the case where the lid portion 44 is opened relative to the surface 26a of the plate-shaped portion 26.

[0055] First, as shown in Figure 2, the user inserts their fingers into the gap between the gripping portion 50 and the bulging portion 40 and pushes the lid portion 44 in the X direction (towards the hinge 46). This causes the lid portion 44 to move in the X direction against the spring force of the leaf spring portion 49, and the two engaging claws 52 (see Figure 3) that are close to the gripping portion 50 are released from their engagement with the two engaging holes 38. As the lid portion 44 moves in the X direction, the two engaging claws 52 on the hinge 46 side engage with the two engaging holes 38.

[0056] Next, the user lifts the gripping portion 50 while pushing the lid portion 44 in the X direction. This causes the lid portion 44 to rotate relative to the surface 26a of the plate-shaped portion 26 around the hinge 46. As the lid portion 44 rotates relative to the surface 26a of the plate-shaped portion 26, the housing opening 34 is exposed. This allows the user to connect an external connector (not shown) to the connector 22 through the housing opening 34.

[0057] As shown in Figure 5, when the user pulls the lid 44 in the Z direction, the first partial hook 54a and the second partial hook 54b move in the Z direction and come into contact with the back surface 26b of the plate-shaped portion 26. The first partial hook 54a and the second partial hook 54b catch on the back surface 26b of the plate-shaped portion 26, which prevents the lid 44 from detaching from the housing member 12.

[0058] Next, we will describe the case where the user pulls the lid portion 44 with a tensile force greater than the tensile strength of the third connection portion 56c.

[0059] In this case, as shown in Figure 6, the narrow portion 60 of the third connecting portion 56c (see Figure 5) is cut off. As a result, the first portion hook 54a is supported only by the first connecting portion 56a. The second portion hook 54b is supported only by the second connecting portion 56b. Because the third connecting portion 56c is cut off, the maximum dimension L3 in the Y direction of the cut hook 48 may be smaller than the maximum dimension L1 in the Y direction of the hook 48 before cutting (see Figure 5) (L1 > L3).

[0060] In this state, when the user pulls the lid 44, the first portion hook 54a and the second portion hook 54b come into contact with the back surface 26b of the plate-like portion 26. When the user pulls the lid 44 further, the hook 48 bends due to the resistance of the plate-like portion 26 to the pulling force, causing the first portion hook 54a and the second portion hook 54b to move closer to each other. This allows the user to pull up the hook 48 through the housing opening 34. As a result, the user can remove the cover 14 from the housing 10.

[0061] This embodiment provides the following effects.

[0062] The tensile strength of the third connecting portion 56c is lower than that of both the first connecting portion 56a and the second connecting portion 56b. Therefore, if a user pulls the lid portion 44 with a force exceeding the tensile strength of the third connecting portion 56c, the narrow portion 60 of the third connecting portion 56c will be cut, as shown in Figure 6. Even when the narrow portion 60 is cut, the first portion hook 54a is supported by the first connecting portion 56a, and the second portion hook 54b is supported by the second connecting portion 56b. Therefore, when a user pulls up the hook 48, it is possible to prevent the hook 48 from remaining inside the storage portion 24, and the hook 48 will be easier to remove.

[0063] As shown in Figure 4, the first connecting portion 56a, the second connecting portion 56b, and the third connecting portion 56c extend parallel to the Y direction along the direction (Z direction) from the base portion 48a of the hook 48 toward the tip portion 48b of the hook 48. The third connecting portion 56c is located between the first connecting portion 56a and the second connecting portion 56b. As a result, even if the narrow portion 60 is cut off, the first connecting portion 56a and the second connecting portion 56b can support the first portion hook 54a and the second portion hook 54b in a balanced manner (see Figure 6). Consequently, when a user pulls up the hook 48, it becomes easier to remove the hook 48.

[0064] As shown in Figure 4, the first partial hook 54a and the second partial hook 54b protrude in different directions from each other. As a result, as shown in Figure 5, when the user pulls the lid 44, both the first partial hook 54a and the second partial hook 54b come into contact with the plate-shaped portion 26 of the housing member 12. This effectively prevents the lid 44 from detaching from the housing member 12.

[0065] In the first section hook 54a, the first linear section 62a extending from the first connecting section 56a and the second linear section 64a extending from the third connecting section 56c are connected to each other at the intermediate section 58a. In the second section hook 54b, the third linear section 62b extending from the second connecting section 56b and the fourth linear section 64b extending from the third connecting section 56c are connected to each other at the intermediate section 58b. As a result, when the narrow section 60 is cut (see Figure 6), the first section hook 54a and the second section hook 54b can be deformed to be closer to each other. This makes it easier for the user to pull up the hook 48.

[0066] The minimum cross-sectional area of ​​the third connecting portion 56c (the cross-sectional area of ​​the narrow portion 60) is smaller than both the minimum cross-sectional area of ​​the first connecting portion 56a and the minimum cross-sectional area of ​​the second connecting portion 56b. As a result, the third connecting portion 56c can be cut before the first connecting portion 56a and the second connecting portion 56b.

[0067] As shown in Figure 4, when the narrow portion 60 is not cut, the maximum dimension L1 of the hook 48 in the Y direction is greater than the maximum dimension L2 of the insertion hole 36 (L1 > L2). As a result, when the user pulls the lid portion 44, both the first portion hook 54a and the second portion hook 54b come into contact with the housing member 12, effectively preventing the lid portion 44 from detaching from the housing member 12.

[0068] As shown in Figure 6, when the narrow portion 60 is cut off, the maximum dimension L3 of the hook 48 in the Y direction can be less than or equal to the maximum dimension L2 of the insertion hole 36 (L2 > L3). This allows the first portion hook 54a and the second portion hook 54b to be easily pulled out through the insertion hole 36.

[0069] Since the hook 48 is flexible, when the first portion hook 54a and the second portion hook 54b are pulled out through the insertion hole 36, the first portion hook 54a and the second portion hook 54b can be easily bent. This makes it even easier to pull out the first portion hook 54a and the second portion hook 54b.

[0070] Because the hook 48 is made of polypropylene, it can be easily bent.

[0071] Since the lid portion 44 and the hook 48 are integrally molded, the cover 14 can be easily manufactured. Furthermore, since the number of parts in the housing 10, including the cover 14, can be reduced, the manufacturing cost of the cover 14 can be reduced.

[0072] As shown in Figure 3, since the hook 48 is connected to the lid 44 via the hinge 46, the lid 44 can be easily rotated around the hinge 46.

[0073] Since the housing 10 includes a cover 14 and a housing member 12, the above effects can be easily obtained.

[0074] Since connector 22 is a USB connector, it is possible to suitably connect the USB external connector and connector 22.

[0075] The following additional information is disclosed regarding the above embodiments.

[0076] (Note 1) The cover (14) of the present disclosure includes a lid portion (44) capable of closing a housing opening (34) formed in a housing member (12) provided in a receiving opening (19), and a hook (48) inserted through a through hole (36) provided in the housing member and for hooking the lid portion to the housing member, wherein the hook comprises a first partial hook (54a) connected to the lid portion via a first connecting portion (56a) and a second partial hook (54b) connected to the lid portion via a second connecting portion (56b), and both the first partial hook and the second partial hook are further connected to the lid portion via a third connecting portion (56c), wherein the tensile strength of the third connecting portion is lower than that of the first connecting portion and the tensile strength of the second connecting portion.

[0077] (Note 2) In the cover described in Appendix 1, the first connecting portion, the second connecting portion, and the third connecting portion extend parallel to each other along the direction from the base (48a) of the hook toward the tip (48b) of the hook, and the third connecting portion may be located between the first connecting portion and the second connecting portion.
