DETAILED DESCRIPTION

[0023] Hereinafter, embodiments of the electronic device of the present invention will be described in detail based on the drawings. However, the present invention is not limited to the embodiments.

[0024] Figure 1 It is a perspective view of a notebook PC as an electronic device 10 according to an embodiment of the present invention. The electronic device of the present invention may have a flat housing such as a mobile tablet terminal, for example.

[0025] The electronic device 10 is configured such that the cover 14 can be opened and closed relative to the housing 12 by the hinge 16, and becomes compact by closing the cover 14, and is suitable for mobile use. A display device 18, an electronic device 20, etc., which occupy most of the area of ​​the cover 14, are provided on the front of the cover 14. With respect to the housing 12, the side opposite to the display device 18 when the cover 14 is closed is set as the upper side, and the opposite side is set as the lower side. Around the socket connector 38 described later, the side of the housing 12 is set as the outer side, and conversely, the inside of the housing 12 is set as the inner side. However, the use of the electronic device 10 is not limited to these directions.

[0026] The housing 12 is a flat horizontal rectangular shape consisting of an upper plate 22, a lower plate 24, and side plates 26 forming the periphery. The side plates 26 are formed by vertical walls erected from the edge of the upper plate 22. That is, the upper plate 22 and the side plates 26 are integrated and form a shallow bathtub shape. The lower plate 24 forms an inclined plate 28 (see FIG. 1 ) whose end is close to the upper plate 22 and is in contact with the lower end of the side plate 26. Figure 5 ). Therefore, the side plate 26 is thinner than the thickness of the housing 12 to achieve a suitable appearance. The side plate 26 is, for example, about 1 / 2 the thickness of the housing 12. The inclined plate 28 is integrated with the lower plate 24 and is considered as a part of the lower plate 24, but the portion of the lower plate 24 other than the inclined plate 28 is set as the bottom plate 24a (refer to Figure 5 ).

[0027] In the upper plate 22 of the housing 12, a keyboard device 30 is provided on the inner side and a touch pad 32 is provided on the near side. Inside the housing 12, a substrate 34 is provided on the inner side and a battery 36 is provided on the near side. In addition, a storage device, a communication device, a cooling device, etc. not shown are also provided. The substrate 34 is fixed to the inner surface 22a of the upper plate 22 (see Figure 5 The substrate 34 is a motherboard that controls the entire electronic device 10. The upper plate 22 has a certain thickness in order to fix the keyboard device 30, the touch panel 32, the substrate 34, etc. (see Figure 5 ), and the side plate 26 is an integral structure, thereby achieving high rigidity. The upper plate 22 can ensure particularly high rigidity by being formed of a metal material, but it can also be a resin material depending on conditions. In contrast, the lower plate 24 only needs to basically cover the lower surface of the housing 12, so it is thinner than the upper plate 22 (see Figure 5 ) Low rigidity.

[0028] The left-right width of the substrate 34 is slightly smaller than that of the housing 12. Figure 1 A socket connector 38 is installed at the right end of the HDMI port. The socket connector 38 is, for example, a HDMI (High Definition Multimedia Interface: registered trademark) with standardized specifications and shapes. The socket connector 38 may also be a USB (Universal Serial Bus) or the like. Figure 1 In the example shown in FIG. 1 , the socket connector 38 and the cover 40 are located on the right side of the housing 12 , but they may also be located on the left side, near the front side, or in the back side. The socket connector 38 may also be provided on a sub-substrate other than the substrate 34 .

[0029] Figure 2 It is a partially cutaway perspective view showing the receptacle connector 38 and its surroundings in the side plate 26 , with the cover 40 in a closed state. Figure 3 It is a perspective view showing the receptacle connector 38 and its surroundings in the side plate 26, with the cover 40 in an open state. Figure 4 It is a perspective view showing a state where the plug connector 44 is connected to the receptacle connector 38 and its surroundings in the side plate 26 .

[0030] like Figure 2 As shown, a portion of the socket connector 38 is covered by a cover 40 in a closed state. The cover 40 is elastically biased upward and is maintained in a closed state in the absence of external force. A cutout 40a is formed in the cover 40. The cover 40 and the block 48 (see Fig.10 ) and the coil spring 50 together constitute the cover assembly 42. The plug insertion opening 38a of the socket connector 38 is directed to the outside of the housing 12, and is partially exposed from the cutout 40a, but at least the lower part is covered by the cover 40. That is, the cover 40 and the cover assembly 42 having the cover 40 as a component constitute a protective cover for the socket connector 38.

[0031] like Figure 3 As shown, the cover 40 is an openable and closable type, and is opened by slightly lowering it downward, so that the plug insertion opening 38a is exposed until the lower part. The cover 40 can be opened by pressing the cutout 40a manually, or by pressing the cutout 40a by holding the plug connector 44.

[0032] like Figure 4 As shown, by opening the cover 40 , the plug connector 44 can be connected to the receptacle connector 38 .

[0033] Figure 5 is based on Figure 2 A cross-sectional view taken along the line V to V in FIG. Figure 6 is based on Figure 2 The cross-sectional view of the line VI to VI in FIG. Figure 5, Figure 6 Also included Figure 2 The upper plate 22, the lower plate 24, etc. are shown cut in the figure. Figure 7 It is an exploded perspective view of the receptacle connector 38 and its peripheral components.

[0034] A rectangular cutout 34a is formed at the edge of the substrate 34. The socket connector 38 is mounted on the substrate 34 in a state where a portion is embedded in the cutout 34a, which is a so-called center-mounted method, but it can also be mounted on the substrate 34 without the cutout 34a in a so-called top-mounted method. The plug insertion opening 38a is directed outward. Two screw holes 34b arranged in the front-to-back direction are formed near the cutout 34a in the substrate 34. The socket connector 38 has a tongue 38b in the approximately middle part of the plug insertion opening 38a in the up-down direction. The tongue 38b has electrode terminals on the upper and lower surfaces and protrudes toward the outside. The socket connector 38 has a plug holding cylinder 38c that forms the peripheral wall of the plug insertion opening 38a. The plug holding cylinder 38c is usually made of metal material and is electrically connected to the ground wire. The plug holding cylinder 38c is formed with an inclined cutout 38d at the lower part of the outer side, and the inclined cutout 38d is inclined in a manner to form a gap with a substantially constant interval with the inner surface of the inclined cover 58.

[0035] In the housing 12, a cover fitting notch 46 is formed from a portion of the side plate 26 facing the plug insertion opening 38a to the lower plate 24. The cover fitting notch 46 is composed of an upper notch 46a formed in the side plate 26 and a lower notch 46b formed in the lower plate 24. The lower notch 46b is formed from the inclined plate 28 to the bottom plate 24a, but in the case where the inclined plate 28 is gently inclined and long in the inner and outer directions, it may be formed only in the range of the inclined plate 28.

[0036] A block-shaped relay fixture 52 is fixed to the inner surface 22a of the upper plate 22. The relay fixture 52 may be a separate body from the upper plate 22 and fixed to the inner surface 22a by press-fitting, bonding, etc., or may be integral with the upper plate 22. Studs 52a arranged in front and back are provided on the lower surface of the relay fixture 52. The substrate 34 is clamped between the block 48 and the studs 52a of the relay fixture 52.

[0037] Two screws 54 for fixing are respectively passed through screw holes 48aa formed in the block 48, and further passed through screw holes 34b of the base plate 34 to be screwed into studs 52a of the relay fixture 52. That is, the base plate 34, the block 48, and the relay fixture 52 are fastened and fixed as a whole by the screws 54. The screws 54 are small, for example, M2 size.

[0038] In addition, Figure 7In order to facilitate understanding, the cover 40 and the block 48 are shown separately, but when the electronic device 10 is assembled, the cover 40, the coil spring (elastic body) 50 and the block 48 are pre-assembled into a cover assembly 42 (see Fig.10 ).

[0039] Figure 8 : is a three-dimensional view of the cover 40. The cover 40 has: a side cover 56, which forms the same plane with the side plate 26 when viewed from the outside in the closed state; an inclined cover 58, which forms the same plane with the inclined plate 28; a lower cover 60, which forms the same plane with the bottom plate 24a; and a rotation axis 62, which is formed along the inner edge of the lower cover 60. The connection portion between the side cover 56 and the inclined cover 58, and the connection portion between the inclined cover 58 and the lower cover 60 are respectively formed in an obtuse angle shape. In the case where the inclined plate 28 is gently inclined and long in the inner and outer directions, the inclined cover 58 can be lengthened to match the inclined plate 28, and the lower cover 60 can be omitted. The rotation axis 62 of the cover 40 is axially supported by the block 48 and rotates, and roughly blocks the cover fitting cutout 46 in the closed state, and exposes the plug insertion opening 38a in the open state.

[0040] The cutout 40a is formed in the side cover 56. The cutout 40a is tapered in two steps 40aa to narrow downward at the front and rear ends in accordance with the lower end shape of the receptacle connector 38, and has a cutout edge 40ab slightly long in the front-rear direction.

[0041] The cover 40 has reinforcing walls 64 at the front and rear ends, respectively, which protrude upward from the inner side of the side cover 56 to the upper surface of the inclined cover 58. The side cover 56 and the reinforcing wall 64 are equal in height. The reinforcing wall 64 has a moderate width in the inner and outer directions and has high strength.

[0042] Each reinforcing wall 64 is provided with a stopper 66, which protrudes in directions away from each other in the front-to-back direction. The stopper 66 is provided near the inner end and the upper end of the reinforcing wall 64, and is slightly away from the outer side surface of the side cover 56. The stopper 66 is substantially rectangular when viewed in the front-to-back direction, has a moderate thickness in the up-down direction, and becomes thicker in the inside-outside direction to have high strength. When the cover 40 is in the open state, the stopper 66 is in contact with the inner surface 26a of the side plate 26 (see Fig.11 ) to limit the displacement in the opening direction. The two outer corners of the stopper 66 are arc-shaped, which can prevent damage to the inner surface 26a caused by contact with the inner surface 26a and prevent the function of the stopper 66 from being lost. The two inner corners of the stopper 66 do not need to be arc-shaped, and in this embodiment, they are C surfaces.

[0043] The rotating shaft 62 is in the shape of a round bar with both ends protruding from the lower cover 60. One end 62a of the rotating shaft 62 protrudes longer than the other end 62b, and a coil spring is provided at this portion (see Figure 7 ) 50. One end 50a and the other end 50b of the coil spring 50 are L-shaped. A spring engaging portion 68 having a mountain shape when viewed in the front-rear direction is provided near one end 62a on the upper surface of the lower cover 60. One end 50a of the coil spring 50 is engaged with a spring hole 68a in the front-rear direction in the spring engaging portion 68.

[0044] The cover 40 is made of a metal material such as aluminum. Figure 6 As shown, each part has a moderate thickness and is high in strength. Each part of the cover 40 is thicker than the lower plate 24, and in particular, the lower cover 60 near the rotation axis 62 is thicker. The side cover 56 and the inclined cover 58 are thinner than the lower cover 60, but have the same thickness as the upper plate 22, and the front and rear ends are reinforced by the reinforcing wall 64, so that sufficient strength is ensured. The above-mentioned inclined cutout 38d forms a gap with a substantially constant interval with the inner surface of the inclined cover 58. The inclined cover 58 is thinner than the lower cover 60, and the range of the inclined cutout 38d can be limited as much as possible. As long as the strength requirements are met, the cover 40 can also be a resin material, or a composite material of metal and resin formed by insert molding, etc.

[0045] Fig. 9 is a three-dimensional diagram of block 48. Fig. 9 , Figure 7 As shown, the block 48 has: a main part 48a of a rectangular parallelepiped that is longer in the front-to-back direction, an axial support part 48b that protrudes outward from both ends of the main part 48a, and a spring engaging piece 48c that protrudes in the front-to-back direction from one end of the main part 48a. The above-mentioned two screw holes 48aa are formed to be arranged front and back in the main part 48a. A U-shaped shaft groove 48ba is formed in the shaft support part 48b, and the shaft groove 48ba opens to the outside. One end 62a and the other end 62b of the rotating shaft 62 are embedded and axially supported in the shaft groove 48ba. The inner edge of the lower cover 60 enters between the two shaft support parts 48b almost without a gap, and the cover 40 is positioned in the front-to-back direction. The cover 40 is made of a metal material such as a stainless steel material and has high strength, but it can also be a resin material as long as the strength conditions are met.

[0046] Fig.10 4 is a perspective view of the cover assembly 42. As described above, the cover assembly 42 is composed of the cover 40, the coil spring 50 and the block 48. The cover 40 is axially supported by the block 48 and is moved in the closing direction ( Fig.10The cover 40 may also be structured to be latched in one of the two open and closed positions instead of being elastically forced. The spring engaging piece 48c is arranged near the inner side of one end 62a of the rotating shaft 62. A spring groove 48ca opening downward is formed in the spring engaging piece 48c. The other end 50b of the coil spring 50 is engaged with the spring groove 48ca. Since the other end 50b is L-shaped, its front end abuts against the inner side surface of the spring engaging piece 48c to prevent the coil spring 50 and the cover 40 from falling off to the outside. The coil portion of the coil spring 50 is slightly compressed, and a light elastic force is applied to the cover 40 in the front-rear direction. As a result, the looseness of the cover 40 in the front-rear direction disappears and becomes stable.

[0047] Such a cover assembly 42 is constructed in that the cover 40 is not axially supported on the upper plate 22, the lower plate 24 or the side plate 26 but is axially supported on the block 48, thereby forming a component body. Therefore, no hinge part is required in the shell 12, and it can be applied to various models without relying on the shape of the shell 12, and is highly versatile.

[0048] The block 48 is screwed to the stud 52a by means of screws 54 (see Figure 7 ) and fixed to the base plate 34, and can be removed from the base plate 34 by pulling out the screws 54. That is, the cover assembly 42 can be attached, detached and replaced relative to the base plate 34.

[0049] The cover assembly 42 can be pre-assembled into an assembly body during the assembly process of the electronic device 10 and can actually be handled as a component, thereby eliminating the need for installation of the coil spring 50 and axial support of the rotating shaft 62. Basically, it can be installed on the housing 12 only by threaded connection of the screw 54, making installation easy.

[0050] Fig.11 is based on Figure 3 The side cross-sectional view along the line XI-XI in FIG. As described above, by pressing the cover 40 downward to open the cover, the plug is inserted into the opening 38a until the lower part is exposed. Fig.11 As shown, the stopper 66 abuts against the inner surface 26 a of the side plate 26 to limit displacement and prevent excessive opening.

[0051] Even when the cover 40 is pressed by a slightly larger force (for example, a force that a person may generate during normal operation), the stopper 66 will not deform because it is moderately thick in the inner and outer directions. A portion of the pressing force generated by the stopper 66 is borne by the inner surface 26a of the side plate 26. In addition, a portion of the force applied to the cover 40 is applied to the upper plate 22 from the rotating shaft 62 via the block 48, the base plate 34, and the relay fixing member 52. The upper plate 22 and the side plate 26 are made of a slightly thicker metal material and have high strength, so they will not deform. However, if the base plate 34 has a sufficiently high strength, or if other studs are provided near the relay fixing member 52, the relay fixing member 52 may be omitted. The lower plate 24 will not be subjected to the force generated by the opening operation of the cover 40, and may be thinner and have lower strength than the upper plate 22 and the side plate 26.

[0052] As shown by the imaginary line, the plug connector 44 connected to the receptacle connector 38 includes a plug 44a inserted into the plug insertion opening 38a, and a housing 44b from which the plug 44a protrudes. The housing 44b has a larger cross-sectional area than the plug 44a, and a step portion 44c is formed between the housing 44b and the plug 44a. The step portion 44c is located slightly outside the side plate 26. The cover 40 does not contact the step portion 44c in the open state where the stopper 66 contacts the inner surface 26a. This is because the rotation shaft 62 is appropriately inside and the upper and lower positions are appropriately set.

[0053] In the fully opened state where the stopper 66 contacts the inner surface 26a, the cover 40 has a slight margin between it and the lower surface of the plug 44a. This is because the position where the rotation is restricted cannot be the same as the normal position when the plug connector 44 is inserted in consideration of manufacturing variations. That is, if there is no external force pressing down, the cover 40 is more stable due to the force of the coil spring 50 than the lower surface of the plug 44a. Fig.11 The state shown is slightly rotated upward to become the following Fig.12 status.

[0054] Fig.12 is based on Figure 4 Side sectional view along line XII-XII in FIG. The cover 40 is elastically biased upward, so that the notch edge 40ab supports the plug 44a from below. The plug retaining cylinder 38c is formed with an inclined notch 38d at the lower portion of the outer side, so that the lower surface plate is shorter than the upper surface plate. The plug 44a inserted into the plug retaining cylinder 38c may become unstable relative to the bottom, but the notch edge 40ab supplements this by supporting from below. The support point of the notch edge 40ab is closer to the outside than the outer end of the upper surface plate of the plug retaining cylinder 38c near the step portion 44c, thereby effectively preventing the plug 44a from moving toward the outside. Fig.12 Tilt in counterclockwise direction.

[0055] Fig.134 is a cross-sectional view of the socket connector 38 and its surroundings when the plug connector 44 is pressed by a slightly larger force (such as a force that a person may generate during normal operation). The plug connector 44 may be pressed by the user unintentionally when the plug connector 44 is inserted into the socket connector 38 or when the electronic device 10 is used. As a result, the plug connector 44 is displaced downward or is subjected to an upward force. Fig.13 The counterclockwise tilting force.

[0056] In this way, Fig.13 As shown in FIG. 1 , the plug connector 44 is displaced downward, but the cover 40 supporting the plug 44a from below is also pressed down, and the stopper 66 abuts against the inner surface 26a of the side plate 26 to prevent further downward displacement. The displacement of the plug connector 44 and the plug 44a is small, and no stress is applied to the tongue 38b embedded in the front end of the plug 44a, and the conductive state of the electrode terminal is maintained. The force applied to the plug connector 44 is reliably supported by the high-strength upper plate 22 and the side plate 26, and the cover 40 is pressed down (see FIG. 1 ). Fig.11 ) is the same. In the state where the plug connector 44 is not subjected to external force and does not move downward (refer to Fig.12 ) below, the stopper 66 may also abut against the inner surface 26a to limit the movement.

[0057] The present invention is not limited to the above-described embodiments, and can of course be freely modified within the scope of the present invention.
