  In recent years, there has been a further demand for cost reduction of electronic devices. Therefore, the present inventors have studied that the flexible cable is omitted and the module is directly connected to the connector of the circuit board.

  However, if the module is directly connected to the connector on the circuit board, the module or the connector may be damaged when subjected to a large impact from the outside.

  The objective of this invention is obtaining the electronic device which can improve impact resistance.

  According to the embodiment, the electronic device includes a housing, a circuit board, a unit, and a buffer unit. The circuit board is mounted with a first connector including a first terminal portion and a first insulating portion that supports the first terminal portion. The unit supports a second terminal portion that can be electrically connected to the first terminal portion over a first position and a second position closer to the first connector than the first position, and the second terminal portion. And a second connector including a second insulating portion that contacts the first insulating portion at the second position. The buffer portion is not in contact with at least one of the casing and the unit at the first position, and a part of the casing and the unit at a position between the first position and the second position. The contact between the first insulating portion and the second insulating portion can be suppressed only after contact with at least one of them.

  According to the present invention, the impact resistance of an electronic device can be improved.

The first wall portion 31 is provided with the opening 23 and the first connector 15 is exposed. The second wall portion 32 stands on the rear side of the HDD unit 22 and faces the HDD unit 22 from the side opposite to the first wall portion 31. The third and fourth wall portions 33 and 34 stand separately on both sides of the HDD unit 22.

  As shown in FIGS. 4 and 9, the fixing portion 27 is provided at the end portion of the HDD accommodating portion 21 that is on the opposite side to the first connector 15. The fixing portion 27 extends rearward from the distal end portion of the second wall portion 32. The fixing portion 27 has a placement surface 36, a screw hole 37, a hook 38, and a recess 39. Each of the hook 38 and the recess 39 is an example of an “engaged portion”.

  The mounting surface 36 extends substantially horizontally and is substantially parallel to the bottom wall portion 25. The screw hole 37 is provided, for example, at a substantially central portion of the fixed portion 27. As shown in FIG. 10, the hook 38 has a first portion 38a protruding from the placement surface 36, and a second portion 38b bent from the tip of the first portion 38a.

  The second portion 38 b protrudes in the direction opposite to the sliding direction of the HDD unit 22. A gap having substantially the same thickness as a mounting portion 57 of the HDD 45 described later is provided between the second portion 38b and the mounting surface 36. As shown in FIG. 12, the recess 39 is recessed inside the housing 6 with respect to the placement surface 36.

  As shown in FIG. 2, the lid mounting portion 28 extends substantially horizontally from the distal end portion of the standing wall portion 26 toward the outside of the HDD accommodating portion 21. As shown in FIGS. 2 and 9, the HDD cover 41 is placed on the lid placing portion 28. The HDD cover 41 has an insertion hole 42. The insertion hole 42 faces the screw hole 37 of the HDD accommodating portion 21. The HDD cover 41 is fixed to the housing 6 by the screws 43 engaging with the screw holes 37 from the insertion holes 42. The HDD cover 41 covers the HDD unit 22 and the HDD housing unit 21 from the outside of the housing 6.

  As shown in FIG. 3, the HDD unit 22 includes an HDD 45 and a holder 46 that holds the HDD 45. The HDD 45 is an example of a “module” and an example of a “storage medium”. The holder 46 is an example of an “attachment sheet metal”.

  The HDD 45 is formed in a rectangular flat shape. The HDD 45 has first and second main surfaces 45a and 45b and a peripheral surface 45c. The first and second main surfaces 45 a and 45 b are surfaces that extend in parallel with the magnetic disk of the HDD 45. As shown in FIG. 9, the first main surface 45 a faces the inner surface of the HDD cover 41. The second main surface 45 b faces the bottom wall portion 25 of the HDD accommodating portion 21.

  The peripheral surface 45c includes a front surface 45ca, a rear surface 45cb, a first side surface 45cc (left side surface), and a second side surface 45cd (right side surface). The front surface 45ca, the rear surface 45cb, the first side surface 45cc, and the second side surface 45cd are the first wall portion 31, the second wall portion 32, the third wall portion 33, and the fourth side portion of the HDD accommodating portion 21, respectively. It faces the wall 34 respectively.

  As shown in FIG. 3, the HDD 45 has first and second end portions 48 and 49 which are end portions in the longitudinal direction. A second connector 51 is provided at the first end 48. The second connector 51 is directly connected (that is, fitted) to the first connector 15. That is, the first connector 15 is inserted into the second connector 51 by sliding the HDD unit 22 as described above.

  As shown in FIG. 7, the second connector 51 includes a socket 52 formed of an insulating material. The socket 52 has a plurality of insertion holes into which the terminal pins 17 are inserted. The socket 52 is an example of a “second contact portion”.

  The first and second connectors 15 and 51 have a predetermined effective fitting length. “Effective fitting length” means a state in which the first and second connectors 15 and 51 are not inserted to the innermost part, that is, the first and second connectors 15 and 51 are 100% fitted to each other. This is a range in which the first and second connectors 15 and 51 are electrically connected to each other in the previous state.

  The effective fitting length of the first and second connectors 15 and 51 is, for example, about 1.5 mm. That is, as shown in FIG. 8, if the gap S between the first and second connectors 15 and 51 (that is, the gap S between the header 16 and the socket 52) is 1.5 mm or less, the first The second connectors 15 and 51 are electrically connected to each other.

  The HDD unit 22 maintains the electrical connection with the first connector 15 and a first position where the header 16 and the socket 52 are separated from each other, and a second position where the header 16 and the socket 52 are in contact with each other. And is held movable. The first position is within the range of the effective fitting length of the first and second connectors 15 and 51, and a gap S is open between the header 16 and the socket 52.

  As shown in FIGS. 3 and 5, the holder 46 is formed of, for example, a sheet metal member. The holder 46 includes first and second holding portions 54 and 55, a connecting portion 56, and an attaching portion 57. The first and second holding portions 54 and 55 are formed in an upright plate shape, and face the first and second side surfaces 45cc and 45cd of the HDD 45.

  The first and second holding portions 54 and 55 extend in the longitudinal direction of the HDD 45 along the first and second side surfaces 45cc and 45cd. The first and second holding portions 54 and 55 extend over substantially the entire length of the HDD 45 in the longitudinal direction. The first and second holding units 54 and 55 sandwich the HDD 45 therebetween. The HDD 45 is fixed to the first and second holding portions 54 and 55 by, for example, screwing.

  As shown in FIGS. 5 and 7, the front end portions of the first and second holding portions 54 and 55 are respectively provided with contact portions 60 (cushion portions and second buffer portions). The abutting portion 60 projects toward the first wall portion 31 (that is, toward the buffer members 71 and 72 described later) and protrudes to a region off the side of the HDD 45. The abutting portion 60 protrudes in a plate shape and has a bent portion 61 at the tip. In the bent portion 61, the plate-like contact portion 60 is bent in the thickness direction.

  The pair of contact portions 60 provided separately in the first and second holding portions 54 and 55 are bent in a direction toward each other, that is, in a direction toward the second connector 51. The bent portion 61 has a contact surface 60 a that faces the first wall portion 31. The contact surface 60 a is substantially parallel to the first wall portion 31.

  As shown in FIGS. 3 and 9, the connecting portion 56 is formed in an upright plate shape and faces the rear surface 45 cb of the HDD 45. The connecting portion 56 connects the rear end portions of the first and second holding portions 54 and 55.

  The attachment portion 57 extends rearward from the end portion of the connecting portion 56 on the HDD cover side. The attachment portion 57 is placed on the placement surface 36 of the HDD accommodating portion 21. The attachment portion 57 has a notch portion 62, an engagement hole 63, an engagement portion 64, and a slit 65. Each of the engagement holes 63 and the engagement portions 64 is an example of an “engagement portion”.

  As shown in FIGS. 3 and 5, the notch 62 is provided at the rear end of the mounting portion 57. As shown in FIG. 6, when the HDD unit 22 is slid and connected to the first connector 15, the notch portion 62 faces the screw hole 37 of the fixing portion 27. The screw 43 passed through the insertion hole 42 of the HDD cover 41 is engaged with the screw hole 37 through the notch 62. Accordingly, the HDD unit 22 is restricted from moving backward by the screw 43 engaged with the screw hole 37, and the position thereof is fixed.

  As shown in FIGS. 5 and 6, the engagement hole 63 engages with the hook 38. The engagement hole 63 has a predetermined length in the sliding direction of the HDD unit 22. As shown in FIG. 10, when the HDD unit 22 is placed in the HDD accommodating portion 21 along the substantially vertical direction, the hook 38 is passed through the engagement hole 63. Thereafter, when the HDD unit 22 is slid in a substantially horizontal direction toward the first connector 15, a part of the mounting portion 57 is placed in the gap between the hook 38 and the mounting surface 36 as shown in FIG. 11. Get in. As a result, the HDD unit 22 does not float from the HDD housing portion 21.

  As shown in FIGS. 5 and 6, the engaging portion 64 is bent so as to enter the concave portion 39, for example, and engages with the concave portion 39. The recess 39 has a predetermined length in the sliding direction of the HDD unit 22. As shown in FIG. 12, when the HDD unit 22 is placed in the HDD accommodating portion 21 along the substantially vertical direction, the engaging portion 64 enters the recess 39. Thereafter, when the HDD unit 22 is slid in a substantially horizontal direction toward the first connector 15, the engaging portion 64 faces the end surface 39 a of the recess 39 with a slight distance, for example, as shown in FIG. 13. . Note that the engaging portion 64 may be in contact with the end surface 39a.

  As shown in FIG. 3, the slit 65 extends in the short direction of the HDD unit 22 (that is, the direction intersecting the sliding direction). For example, several slits 65 are provided. When these several slits 65 are added together, for example, more than half the length of the mounting portion 57 is cut out in the short direction. Thereby, the weak part 66 relatively weak compared with another site | part is formed in a part of attachment part 57. As shown in FIG.

  As shown in FIG. 4, the HDD accommodating portion 21 is provided with first and second buffer members 71 and 72. Each of the first and second buffer members 71 and 72 is an example of the “buffer portion” in the present invention. For convenience of explanation, the first and second buffer members 71 and 72 are hatched in FIGS. 4, 5, and 6.

  The first and second buffer members 71 and 72 are provided on the standing wall portion 26 of the housing 6, for example. The first and second buffer members 71 and 72 are, for example, elastic members, and more specifically rubber members. The first and second buffer members 71 and 72 are formed in, for example, an L shape, and are respectively disposed at corners of the HDD accommodating portion 21.

  As shown in FIG. 7, the first buffer member 71 has first and second portions 71a and 71b formed integrally with each other. The first wall portion 31 faces the contact portion 60 of the holder 46 in the direction in which the first connector 15 faces the second connector 51. The first portion 71 a is attached to the first wall portion 31 and faces the contact portion 60 of the holder 46. The first portion 71 a is substantially parallel to the contact surface 60 a of the contact portion 60.

  The second portion 71b is bent with respect to the first portion 71a. The second portion 71 b is affixed to the third wall portion 33 and faces the first holding portion 54 of the holder 46. The first portion 71a is formed thicker than the second portion 71b.

  As shown in FIG. 4, the second buffer member 72 similarly includes first and second portions 72 a and 72 b that are integrally formed with each other. The first portion 72 a is attached to the first wall portion 31 and faces the contact portion 60 of the holder 46. The second portion 72b is bent with respect to the first portion 72a. The second portion 72 b is attached to the fourth wall portion 34 and faces the second holding portion 55 of the holder 46. The first portion 72a is formed thicker than the second portion 72b.

  As shown in FIGS. 6 and 8, when the second connector 51 of the HDD unit 22 is connected to the first connector 15, the first portions 71a and 72a of the first and second buffer members 71 and 72 are , Abuts against the abutting portion 60 of the holder 46. That is, the first and second buffer members 71 and 72 abut on the holder 46 while the HDD unit 22 is moved from the first position to the second position.

  The first portions 71a and 72a of the first and second buffer members 71 and 72 are within a range in which the first connector 15 is electrically connected to the second connector 51 (that is, an effective fitting length range). The first wall portion 31 and the holder 46 are interposed so as to leave a gap S between the first connector 15 and the second connector 51.

  The gap S is, for example, about 0.5 mm, but the size is not limited as long as it is within the range of the effective fitting length. Note that “leaving a gap between the first connector and the second connector” means that the socket 52 is not in contact with the header 16 as shown in FIG. Means that there is a gap S.

  As shown in FIG. 4, the HDD accommodating portion 21 is provided with a plurality of third buffer members 73. As shown in FIG. 9, the third buffer member 73 faces the second main surface 45 b of the HDD 45. The HDD cover 41 is provided with a plurality of fourth buffer members 74. The fourth buffer member 74 faces the first main surface 45 a of the HDD 45. The fourth buffer member 74 faces the HDD unit 22 from the side opposite to the third buffer member 73. Each of the third and fourth buffer members 73 and 74 is an elastic member, for example, a rubber member in a specific example.

Next, attachment of the HDD unit 22 to the HDD accommodating portion 21 will be described.
The HDD unit 22 is attached to the HDD housing portion 21 with the electronic device 1 upside down, that is, with the lower wall 8 facing upward. As shown in FIG. 5, first, the HDD unit 22 is housed in the HDD housing part 21 along the substantially vertical direction from the upper side with respect to the HDD housing part 21 exposed upward. As a result, as shown in FIGS. 10 and 12, the hook 38 is passed through the engagement hole 63 and the engagement portion 64 is engaged with the recess 39.

  Next, as shown in FIG. 6, the HDD unit 22 is slid in a substantially horizontal direction toward the first connector 15. At this time, the second portions 71 b and 72 b of the first and second buffer members 71 and 72 and the third buffer member 73 serve as a guide for guiding the HDD unit 22.

  Then, as shown in FIG. 8, the abutting portion 60 of the holder 46 abuts on the first portions 71 a and 72 a of the first and second buffer members 71 and 72, thereby stopping the sliding movement of the HDD unit 22. Is done. At this time, a gap S is left between the first and second connectors 15 and 51.

  As shown in FIGS. 11 and 13, when the HDD unit 22 is connected to the first connector 15, a part of the attachment portion 57 enters under the hook 38. Thereby, the HDD unit 22 is temporarily fixed to the HDD accommodating portion 21. Further, the engaging portion 64 faces the end surface 39 a of the recess 39.

  Next, as shown in FIGS. 2 and 9, the HDD cover 41 is placed on the lid placing portion 28. Then, the screw 43 is engaged with the screw hole 37 of the HDD accommodating portion 21 through the insertion hole 42 of the HDD cover 41 and the notch portion 62 of the holder 46. Thereby, the HDD unit 22 is screwed and fixed to the housing 6 at a position where a gap S is left between the first and second connectors 15 and 51.

Next, the operation of the electronic device 1 will be described.
If there is a gap S between the first and second connectors 15 and 51, for example, when the electronic device 1 is accidentally dropped, an impact applied from the outside is applied to the first and second connectors 15 and 51. It is difficult to communicate between 51. Therefore, even when an impact is applied, the first connector 15 and the HDD unit 22 are not easily damaged.

  That is, when an impact is applied to move the HDD unit 22 in the sliding direction, the contact portion 60 of the holder 46 is in contact with the first and second buffer members 71 and 72, so that the HDD unit 22 is in the first state. It is difficult to move toward the connector 15. For this reason, the gap S is easily maintained between the HDD unit 22 and the first connector 15, and an excessive force is unlikely to act on the HDD unit 22 and the first connector 15.

  Further, when an impact is applied from the outside, the contact portion 60 of the holder 46 formed in a plate shape is bent, so that a part of the impact transmitted to the HDD 45 is absorbed and a large impact is prevented from acting on the HDD 45. Is done.

  Further, when an impact is applied from the outside, the attachment portion 57 that has entered under the hook 38 comes into contact with the first portion 38 a of the hook 38. Further, the engaging portion 64 abuts on the end surface 39 a of the recess 39. That is, the engagement hole 63 and the engagement hole 63 are left so as to leave a gap S between the first and second connectors 15 and 51 within a range where the first connector 15 is electrically connected to the second connector 51. The portion 64 contacts the hook 38 and the recess 39. Accordingly, the gap S between the first and second connectors 15 and 51 is more reliably maintained, and damage to the HDD unit 22 and the first connector 15 is suppressed.

  On the other hand, when an impact is applied in a direction opposite to the sliding direction, that is, in the direction in which the HDD unit 22 is removed from the first connector 15, the fragile portion 66 of the mounting portion 57 is bent and the impact is absorbed. As a result, the force applied to the HDD 45 is relaxed.

  When an impact in the short direction of the HDD unit 22 is applied, the second portions 71 b and 72 b of the first and second buffer members 71 and 72 protect the HDD unit 22. Further, when an impact in the thickness direction of the HDD unit 22 is applied, the third and fourth buffer members 73 and 74 protect the HDD unit 22.

  According to such a configuration, the impact resistance of the electronic device 1 can be improved. For comparison, FIG. 17 discloses an electronic device in which no gap exists between the first and second connectors 15 and 51. The socket 52 is in contact with the header 16. According to such a configuration, for example, an impact when the electronic device 1 is accidentally dropped is strongly transmitted between the first and second connectors 15 and 16, and the first connector 15 and the HDD 45 are damaged. There is a fear.

  On the other hand, in the configuration of this embodiment, the buffer members 71 and 72 interposed between the first wall portion 31 and the holder 46 so as to leave a gap S between the first and second connectors 15 and 51 are provided. Thus, even when a large impact is applied to the electronic device 1, direct contact between the first and second connectors 15 and 51 is suppressed. This reduces the risk of damage to the first connector 15 and the HDD unit 22.

  Therefore, impact resistance can be improved in the electronic device 1 in which the HDD unit 22 is directly connected to the connector 15 of the circuit board 14 without using a flexible cable. Since the flexible cable is expensive, if it can be omitted, the cost of the electronic device 1 can be reduced. Furthermore, since the number of parts and weight can be reduced, it becomes easier to manage parts.

  By providing the buffer members 71 and 72 on the first wall portion 31 that faces the holder 46 in the direction in which the first connector 15 faces the second connector 51, the buffer members 71 and 72 become the first wall portion 31. And the holder 45 more securely. For this reason, it becomes easy to maintain the gap S between the first and second connectors 15 and 51.

  When the holder 46 has a contact portion 60 that protrudes in a plate shape toward the buffer members 71 and 72 and has a bent end portion thereof, when the contact portion 60 contacts the buffer members 71 and 72, a large impact is caused.
