Modes for Carrying Out the Invention

[0011] Hereinafter, embodiments for carrying out the invention (hereinafter referred to as embodiments) will be described in detail with reference to the drawings. Note that the present invention is not limited by the following embodiments. In addition, the constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art, substantially identical ones, and those within a so-called equivalent range. Furthermore, the constituent elements disclosed in the following embodiments can be combined as appropriate.

[0012] The in-vehicle device 100 of the embodiment is mounted inside the vehicle. The in-vehicle device 100 is, for example, an AV (Audio Visual) integrated car navigation device. As shown in FIGS. 1 and 2, the in-vehicle device 100 includes an in-vehicle device 10 and a cluster panel 20.

[0013] The in-vehicle device 10 has a display unit 12 and a sub-panel 13 on the front side of the device main body 11. Since the front is arranged forward inside the vehicle in the case of an in-vehicle navigation device mounted inside the vehicle, it is the surface facing backward inside the vehicle. Conversely, the surface facing forward inside the vehicle is defined as the back surface.

[0014] The device main body 11 is a housing with an open front and the other upper, lower, right, left, and back surfaces closed with sheet metal. The device main body 11 houses electronic components and drive components for moving the display unit 12 inside the housing. Although not shown in the figure, brackets are fixed to the right and left sides of the device main body 11, and the device main body 11 is fixed to the vehicle by screwing to the fixing portion on the vehicle side through these brackets.

[0015] In the embodiment, the display unit 12 is formed in a rectangular shape with dimensions larger than those of the device main body 11 in the vertical and horizontal directions, and is disposed on the front side of the device main body 11. The display unit 12 is usually arranged with the display surface 12A facing the front so as to cover the front of the device main body 11. The display unit 12 is composed of, for example, a liquid crystal display (LCD) or an organic electro-luminescence (EL) display. Further, for the display unit 12, for example, a pressure-sensitive touch panel can be applied to the display surface 12A. The display unit 12 is provided movably with respect to the device main body 11. For example, the display unit 12 is provided so as to be tiltable such that the display surface 12A faces upward. Also, the display unit 12 is provided so as to be reversely tiltable such that the display surface 12A faces downward. Further, the display unit 12 is provided so as to be openable and movable to expose a card slot for inserting a storage medium such as a memory card by opening the front of the device main body 11, or a disc slot for inserting a DVD (Digital Versatile Disc) or a CD (Compact Disc).

[0016] In the embodiment, the sub-panel 13 is formed in a rectangular frame shape with dimensions larger than those of the device main body 11 in the vertical and horizontal directions, and is disposed on the front side of the device main body 11 together with the display unit 12. The sub-panel 13 is molded from a synthetic resin material such as an ABS (acrylonitrile-butadiene-styrene) resin. The sub-panel 13 is fixed to the device main body 11. The sub-panel 13 is disposed on the back side of the display unit 12 and abuts against the back side of the display unit 12 to position the display unit 12 when the display unit 12 is arranged with the display surface 12A facing the front so as to cover the front of the device main body 11.

[0017] The cluster panel 20 is formed of a synthetic resin material such as an ABS (acrylonitrile-butadiene-styrene) resin. As shown in FIGS. 1 and 2, the cluster panel 20 is formed so as to surround the display unit 12. The cluster panel 20 has a rectangular frame portion 20A that surrounds the periphery of the display unit 12, and a rectangular window portion 20Aa that opens the display surface 12A of the display unit 12 inside the frame portion 20A. Further, the cluster panel 20 is provided with a push button 20B on the frame portion 20A. The push button 20B operates a switch element provided on the back side by a pressing operation from the front side.

[0018] As shown in FIG. 2, for the in-vehicle device 10 and the cluster panel 20 to transmit and receive a signal in which the push button 20B of the cluster panel 20 operates the switch element, a harness 30 is interposed therebetween. The harness 30 is divided into a device-side harness 30A on the in-vehicle device 10 side and a panel-side harness 30B on the cluster panel 20 side, and is electrically connected via a connector 31. One end of the device-side harness 30A penetrates the sheet metal of the device body 11 in the in-vehicle device 10 and is connected to an electronic device inside the device body 11. A male connector 31A is connected to the other end of the device-side harness 30A drawn out to the outside of the device body 11. One end of the panel-side harness 30B is connected to a substrate on the back side of the frame portion 20A in the cluster panel 20 where the switch element of the push button 20B is mounted. A female connector 31B is connected to the other end of the panel-side harness 30B drawn out from the substrate to the outside. The connector 31 electrically connects the device-side harness 30A and the panel-side harness 30B by connecting the male connector 31A and the female connector 31B to each other. In the in-vehicle device 100 of the embodiment, the harness 30 (31A, 31B) and the connector 31 (31A, 31B) are respectively arranged on the left and right of the in-vehicle device 10 and the cluster panel 20.

[0019] In the in-vehicle device 100 of the embodiment, in the sub-panel 13, a hook portion 32 is provided on the back side that protrudes upward and to the left and right sides from the device main body 11. The hook portion 32 hooks the middle of the device-side harness 30A and the middle of the panel-side harness 30B. By having the hook portion 32, the in-vehicle device 100 can arrange the device-side harness 30A and the panel-side harness 30B at predetermined positions. Here, conventionally, to prevent abnormal noise, a connector was fixed to the in-vehicle device side with tape or a cushioning material was wound around it. However, since the position of the connector was not determined when assembling the in-vehicle device 10 or the cluster panel 20, there was a risk of the harness being caught. As a result, the in-vehicle device 100 of the embodiment can suppress the harness 30 from being caught and the generation of abnormal noise from the harness 30 during vibration by having the hook portion 32.

[0020] As shown in FIG. 2, the fixing structure of the embodiment is provided on the back surface 13A that protrudes to the left and right sides from the device main body 11 in the sub-panel 13 for attaching the male connector 31A. As shown in FIG. 3, the male connector 31A has a locking claw 31Ab provided on one peripheral surface 31Aa of the four peripheral surfaces formed in a substantially rectangular shape. The locking claw 31Ab is provided by cutting out a support portion 31Ac formed to bulge in an arch shape on the peripheral surface 31Aa. The support portion 31Ac (locking claw 31Ab) has a gap 31Ad with respect to the peripheral surface 31Aa. The locking claw 31Ab has a main body portion 31Aba integrally provided on the support portion 31Ac and is formed in a plate-like shape extending toward the tip 31Abb which is the free end, so that it can be elastically deformed on the side approaching and separating from the peripheral surface 31Aa. The locking claw 31Ab has a locking surface 31Abc extending toward the peripheral surface 31Aa side and facing the main body portion 31Aba side on the tip 31Abb side. The locking claw 31Ab has an inclined surface 31Abd from the locking surface 31Abc toward the tip 31Abb. The female connector 31B is inserted and fitted into the male connector 31A from the upper end side having the support portion 31Ac (locking claw 31Ab). The other end of the device-side harness 30A is connected to the lower end side of the male connector 31A. The configuration of such a male connector 31A is common.

[0021] The fixing structure of the embodiment includes a locking portion 1 for locking the locking claw 31Ab, a locking restricting portion 2, and a position restricting portion 3.

[0022] As shown in FIGS. 3 to 7, the locking portion 1 is integrally formed and fixed to the back surface 13A of the sub-panel 13 made of a synthetic resin material, and has a plate-like rib 1a protruding from the back surface 13A and a locking piece 1b provided across the rib 1a. The rib 1a protrudes from the back surface 13A toward the back side and is provided to extend in the vertical direction, and a plurality (two in the embodiment) are provided side by side in the horizontal direction. The locking piece 1b is provided across the protruding end of each rib 1a so that the plate surface 1ba is arranged along the back surface 13A, and closes a part of the back side of each rib 1a, and has a gap 1c between it and the back surface 13A. As shown by the arrow S in FIG. 3, the locking portion 1 slides the male connector 31A along the back surface 13A and the plate surface 1ba from above, so that, as shown in FIG. 4, the locking claw 31Ab of the male connector 31A is inserted into the gap 1c between the ribs 1a from the tip 31Abb. The locking claw 31Ab is inserted along the plate surface 1ba of the locking piece 1b, the inclined surface 31Abd gets over the locking piece 1b, and the locking surface 31Abc is hooked on the end surface 1bb of the locking piece 1b by the elastic force of the main body portion 31Aba approaching the peripheral surface 31Aa. Thereby, the locking portion 1 locks the male connector 31A.

[0023] In the fixing structure of the embodiment, since the locking portion 1 is configured such that the locking claw 31Ab of the male connector 31A is inserted and locked along the back surface 13A of the sub-panel 13, compared with the configuration in which the locking claw 31Ab of the male connector 31A is inserted and locked toward the back surface 13A of the sub-panel 13, the protruding height (length) from the back surface 13A can be reduced, and when the female connector 31B is detached from the male connector 31A, or when the in-vehicle device 10 and the cluster panel 20 are attached and detached, the situation where the locking claw 31Ab of the male connector 31A or the locking portion 1 is damaged due to an external load on the male connector 31A is prevented. Further, in the fixing structure of the embodiment, since the locking portion 1 is formed based on the rib 1a protruding from the back surface 13A made of a synthetic resin material by integral molding, the generation of sink marks on the front side of the plate surface of the sub-panel 13 is prevented.

[0024] The locking regulation part 2 is fixed below the locking piece 1b. The locking regulation part 2 of the embodiment is formed in a beam shape connecting the middle parts where the respective ribs 1a protrude. As shown in FIGS. 4 and 5, this locking regulation part 2 abuts against the inclined surface 31Abd of the locking claw 31Ab in a state where the male connector 31A is locked to the locking part 1.

[0025] By abutting against the inclined surface 31Abd of the locking claw 31Ab, the locking regulation part 2 biases the locking claw 31Ab in a direction away from the circumferential surface 31Aa as shown in FIGS. 4 and 5. The locking claw 31Ab is pushed in a direction away from the circumferential surface 31Aa against the elastic force of the main body part 31Aba approaching the circumferential surface 31Aa, and while generating an elastic force approaching the circumferential surface 31Aa, the locking allowance H of the locking surface 31Abc with respect to the locking piece 1b becomes smaller. The locking allowance H is the dimension (width) from the plate surface 1ba of the locking piece 1b along which the locking claw 31Ab extends to the tip of the locking surface 31Abc on the locking surface 31Abc caught by the end face 1bb of the locking piece 1b. When the locking regulation part 2 is not provided, as shown by the dashed-dotted line in FIG. 5, the locking claw 31Ab has a locking allowance H' where all the locking surfaces 31Abc are caught by the end face 1bb of the locking piece 1b. Therefore, when the locking regulation part 2 is provided, the locking allowance H is smaller than the locking allowance H'. That is, the locking regulation part 2 abuts against the inclined surface 31Abd of the locking claw 31Ab to suppress the locking allowance H of the locking surface 31Abc to the locking piece 1b. When the locking allowance H of the locking surface 31Abc to the locking piece 1b is suppressed, the locking surface 31Abc is likely to come off from the locking piece 1b. As a result, the fixing structure of the embodiment can facilitate the removal of the male connector 31A. Incidentally, in the fixing structure of the embodiment, the locking regulation part 2 abuts against the inclined surface 31Abd of the locking claw 31Ab to suppress the locking allowance H of the locking surface 31Abc. At this time, since the elastic force applied to the main body part 31Aba is within the range where the main body part 31Aba elastically deforms, an excessive load is not applied to the main body part 31Aba.

[0026] Note that the locking claw 31Ab of the male connector 31A in the embodiment has an interference fit structure. The interference fit structure means that, as shown by the dashed line in Fig. 5, when the locking restriction portion 2 is not provided, with the locking claw 31Ab locked to the locking piece 1b, the locking surface 31Abc of the locking claw 31Ab forms an obtuse angle θ' with respect to the plate surface 1ba of the locking piece 1b. When the locking surface 31Abc of the locking claw 31Ab forms an obtuse angle θ' with respect to the plate surface 1ba of the locking piece 1b, if an external force is generated in the extraction direction S' opposite to the insertion direction S of the male connector 31A, a vector component force V' is generated such that the locking claw 31Ab presses against the plate surface 1ba of the locking piece 1b, and the locking surface 31Abc acts so as to be more hooked to the end surface 1bb of the locking piece 1b. Therefore, in the case of the interference fit structure, the locking surface 31Abc of the locking claw 31Ab cannot be easily removed from the end surface 1bb of the locking piece 1b, and the male connector 31A can be firmly fixed. On the other hand, in the interference fit structure, when removing the male connector 31A, it becomes necessary to forcibly remove the locking surface 31Abc of the locking claw 31Ab from the end surface 1bb of the locking piece 1b, and there is a risk that the main body portion 31Aba, which is an elastic part, may turn white or be damaged.

[0027] In this regard, as shown in FIG. 5, the fixing structure of the embodiment has the locking restriction portion 2, so that in a state where the locking claw 31Ab is locked to the locking piece 1b, the locking surface 31Abc of the locking claw 31Ab forms an acute angle θ with the plate surface 1ba of the locking piece 1b. This acute angle θ is called the escape angle. That is, when the locking surface 31Abc of the locking claw 31Ab forms an acute angle θ (escape angle) with the plate surface 1ba of the locking piece 1b, when an external force is generated in the extraction direction S' opposite to the insertion direction S of the male connector 31A, a vector component force V is generated so that the locking claw 31Ab separates from the plate surface 1ba of the locking piece 1b, and the locking surface 31Abc acts so as to come off with respect to the end surface 1bb of the locking piece 1b, making it easier for the locking surface 31Abc to come off from the locking piece 1b. As a result, the fixing structure of the embodiment can facilitate the removal of the male connector 31A. It should be noted that although it is conceivable to provide an inclination at the end surface 1bb of the locking piece 1b so that the vector component force V is generated, it is difficult to mold the inclination of the end surface 1bb in consideration of mold release. In the fixing structure of the embodiment, the end surface 1bb is formed substantially orthogonal to the insertion direction S (plate surface 1ba). Here, with the above configuration, the locking margin H of the locking surface 31Abc with respect to the locking piece 1b is suppressed, and the locking surface 31Abc is more likely to come off from the locking piece 1b. However, since the locking claw 31Ab is biased in a direction approaching the peripheral surface 31Aa by the elastic force of the elastically deformable main body portion 31Aba, the holding force of the locking can be ensured.

[0028] Also, in the fixing structure of the embodiment, as shown in FIG. 6, the locking restriction portion 2 may be arranged to face the locking piece 1b. When the locking restriction portion 2 is arranged to face the locking piece 1b, when the locking restriction portion 2 abuts on the inclined surface 31Abd to reduce the locking margin H, the distance L between the locking restriction portion 2 and the locking piece 1b becomes smaller compared to FIG. 5. That is, the locking restriction portion 2 abuts on the inclined surface 31Abd at a position closer to the locking surface 31Abc. When the distance L is small, the position of the inclined surface 31Abd with respect to the end surface 1bb of the locking piece 1b can be set at a position close to the inclined surface 31Abd, making it easier to adjust the locking margin H. As a result, the fixing structure of the embodiment can simplify the design for facilitating the removal of the male connector 31A.

[0029] The position regulating portion 3 is integrally formed on the back surface 13A of the sub-panel 13 made of a synthetic resin material, and includes at least one of a first position regulating portion 3A, a second position regulating portion 3B, and a third position regulating portion 3C.

[0030] The first position regulating portion 3A is provided on the back side in the insertion direction S of the male connector 31A from the locking portion 1. The first position regulating portion 3A is composed of a plate-like rib protruding from the back surface 13A of the sub-panel 13 by integral molding. The rib forming the first position regulating portion 3A communicates with the rib 1a of the locking portion 1. This first position regulating portion 3A is provided so as to be able to contact a part (circumferential surface 31Aa) of the male connector 31A on the back side in the insertion direction S from the locking claw 31Ab, as shown by the broken line P1 in FIG. 4, in a state where the male connector 31A is locked to the locking portion 1.

[0031] Here, when the female connector 31B is attached to and detached from the male connector 31A, or when the panel-side harness 30B of the female connector 31B is pulled during the attachment and detachment of the in-vehicle device 10 and the cluster panel 20, as shown in FIG. 4, an external force F1 is generated toward the back side on the upper portion of the female connector 31B. In such a case, the male connector 31A is pulled on the upper side with the position of the locking claw 31Ab as a base point toward the back side, and the lower side to which the device-side harness 30A is connected moves toward the front side. However, in the fixing structure of the embodiment, as surrounded by the broken line P1 in FIG. 4, since the first position regulating portion 3A is provided so as to be able to contact a part (circumferential surface 31Aa) of the male connector 31A, it supports the lower side of the male connector 31A moving toward the front side and regulates the above movement. Therefore, the fixing structure of the embodiment prevents a situation where the locking claw 31Ab of the male connector 31A is unexpectedly disengaged from the locking piece 1b due to an external load, or the locking claw 31Ab or the locking portion 1 of the male connector 31A is damaged. Further, in the fixing structure of the embodiment, since the first position regulating portion 3A is composed of a rib protruding from the back surface 13A made of a synthetic resin material by integral molding, it prevents the occurrence of sink marks on the front side of the plate surface of the sub-panel 13.

[0032] The second position restricting portion 3B is provided on the front side of the insertion direction S of the male connector 31A with respect to the locking portion 1. The second position restricting portion 3B is composed of a plate-like rib protruding integrally from the back surface 13A of the sub-panel 13. The rib forming the second position restricting portion 3B communicates with the rib 1a of the locking portion 1. This second position restricting portion 3B is provided so as to be able to contact a part (support portion 31Ac (or circumferential surface 31Aa)) of the male connector 31A on the front side of the insertion direction S with respect to the locking claw 31Ab, as shown by the broken line P2 in FIGS. 4 and 5, in a state where the male connector 31A is locked to the locking portion 1.

[0033] Here, when the device-side harness 30A is pulled when attaching / detaching the in-vehicle device 10 and the cluster panel 20, as shown in FIG. 4, an external force F2 is generated toward the back surface on the lower side portion of the female connector 31B in the male connector 31A. In such a case, the male connector 31A is pulled on the lower side toward the back surface with the position of the locking claw 31Ab as a base point, and the upper side to which the device-side harness 30A is connected moves to the front side. However, in the fixing structure of the embodiment, as surrounded by the broken line P2 in FIG. 4, since the second position restricting portion 3B is provided so as to be able to contact a part (support portion 31Ac) of the male connector 31A, it supports the upper side of the male connector 31A moving to the front side and restricts the above movement. Therefore, the fixing structure of the embodiment prevents a situation where the locking claw 31Ab of the male connector 31A is unexpectedly disengaged from the locking piece 1b or the locking claw 31Ab or the locking portion 1 of the male connector 31A is damaged due to an external load. Further, in the fixing structure of the embodiment, since the second position restricting portion 3B is composed of a rib protruding integrally from the back surface 13A made of a synthetic resin material, it prevents the generation of sink marks on the front side of the plate surface of the sub-panel 13.

[0034] The third position restricting portion 3C is provided on the side portion of the insertion direction S of the male connector 31A with respect to the locking portion 1. The third position restricting portion 3C is composed of a plate-like rib protruding integrally from the back surface 13A of the sub-panel 13. This third position restricting portion 3C is provided so as to be able to contact a part (support portion 31Ac) of the male connector 31A on the side portion of the insertion direction S with respect to the locking claw 31Ab, as shown by the broken line P3 in FIG. 7, in a state where the male connector 31A is locked to the locking portion 1.

[0035] Here, when the male connector 31A is detached from or attached to the female connector 31B, or when the in-vehicle device 10 and the cluster panel 20 are attached or detached, and is pushed from the side, as shown in FIG. 7, an external force F3 is generated laterally. In such a case, the male connector 31A will be pushed laterally. However, in the fixing structure of the embodiment, as surrounded by the broken line P3 in FIG. 7, since the third position regulating portion 3C is provided so as to be able to contact a part (support portion 31Ac) of the male connector 31A, it supports the male connector 31A moving laterally and regulates the above movement. Therefore, the fixing structure of the embodiment prevents a situation where the locking claw 31Ab of the male connector 31A is unexpectedly disengaged from the locking piece 1b or the locking claw 31Ab or the locking portion 1 of the male connector 31A is damaged due to an external load. Further, in the fixing structure of the embodiment, since the third position regulating portion 3C is formed of a rib protruding integrally from the back surface 13A made of a synthetic resin material, it prevents the generation of sink marks on the front side of the plate surface of the sub-panel 13.

[0036] In the fixing structure of the embodiment, as shown in FIG. 7, the device main body 11 is disposed on the right side portion in the insertion direction S of the male connector 31A with respect to the locking portion 1. And when an external force F3 is generated toward the right side in the male connector 31A, there is a concern about a collision with the device main body 11. For this reason, in the fixing structure of the embodiment, the third position regulating portion 3C is disposed on the right side portion in the insertion direction S of the male connector 31A with respect to the locking portion 1 to prevent the male connector 31A from colliding with the device main body 11. Also, in the fixing structure of the embodiment, since the male connector 31A is difficult to be pushed from the right side due to the presence of the device main body 11, the third position regulating portion 3C is not disposed on the left side portion in the insertion direction S of the male connector 31A with respect to the locking portion 1. However, as shown by the two-dot chain line in FIG. 7, the third position regulating portion 3C may be disposed on the left side portion in the insertion direction S of the male connector 31A with respect to the locking portion 1 as necessary.

[0037] Thus, the fixing structure of the embodiment includes a locking portion 1 that locks the locking surface 31Abc with respect to an elastic deformable main body portion 31Aba, a locking surface 31Abc formed on the main body portion 31Aba, and a locking claw 31Ab having an inclined surface 31Abd extending from the locking surface 31Abc toward the tip 31Abb, and a locking restriction portion 2 that abuts against the inclined surface 31Abd of the locking claw 31Ab to suppress the locking allowance H of the locking surface 31Abc to the locking portion 1.

[0038] According to this fixing structure, by suppressing the locking allowance H of the locking surface 31Abc to the locking portion 1 by the locking restriction portion 2, the locking surface 31Abc is likely to come off from the locking portion 1. As a result, the fixing structure of the embodiment can facilitate removal.

[0039] Further, in the fixing structure of the embodiment, the locking restriction portion 2 abuts against the inclined surface 31Abd at a position where the locking surface 31Abc forms an acute angle θ with respect to the locking portion 1.

[0040] According to this fixing structure, a vector component force V is generated such that the locking claw 31Ab is separated from the plate surface 1ba of the locking piece 1b by an external force, and the locking surface 31Abc acts to come off with respect to the end surface 1bb of the locking piece 1b, making the locking surface 31Abc likely to come off from the locking portion 1. As a result, the fixing structure of the embodiment can facilitate removal.

[0041] Further, in the fixing structure of the embodiment, the locking restriction portion 2 is disposed to face the locking portion 1.

[0042] According to this fixing structure, when the locking restriction portion 2 abuts against the inclined surface 31Abd to reduce the locking allowance H, the distance L between the locking restriction portion 2 and the locking portion 1 becomes smaller, and the position of the inclined surface 31Abd with respect to the locking portion 1 can be set at a position close to the inclined surface 31Abd, so that the adjustment of the locking allowance H becomes easier. As a result, the fixing structure of the embodiment can easily achieve a design that facilitates removal.

[0043] Further, in the fixing structure of the embodiment, a position restricting portion 3 (3A, 3B, 3C) provided on the back surface 13A, which is a fixing member having a locking portion 1, is provided so as to be able to abut against the male connector 31A, which is a member to be fixed having a locking claw 31Ab.

[0044] According to this fixing structure, the position restricting portion 3 restricts the movement of the male connector 31A due to an external load. As a result, the fixing structure of the embodiment prevents a situation in which the locking claw 31Ab of the male connector 31A, which is a member to be fixed, and the locking portion 1 of the fixing member are damaged due to an external load.
