Description

  The present invention relates to a component mounting structure attached to a support member with a predetermined direction, and more particularly to a structure for guiding the orientation of the component.

  Conventionally, an electronic device in which a microphone is accommodated in a housing is known. A microphone used for this type of electronic device includes a microphone body and a flexible cable drawn from the microphone body. The cable has a connector at its tip, and this connector is connected to a printed wiring board inside the housing.

  According to the conventional electronic device, the microphone main body of the microphone is held by the microphone support portion formed in the housing. Therefore, the position of the microphone main body with respect to the housing is fixedly fixed, and when the electronic device is assembled, there is no problem with the attachment position and orientation of the microphone main body.

  However, since the cable drawn from the microphone main body is flexible and has no fixed direction, the cable may be mistakenly routed through a region outside the normal route. For this reason, when an electronic device is assembled, it cannot be denied that the cable interferes with other circuit components or is caught by components located around the cable.

  On the other hand, Patent Document 1 discloses a power strip adapted to prevent erroneous assembly. In this power tap, when placing a pair of terminal boards in the case, one terminal board located on the front side is marked with an arrow.

According to this configuration, by arranging the terminal board in the case with the marked surface as the surface, the front and back of the terminal board will not be mistaken, and the terminal board can be incorporated into the case in a regular orientation. it can.

The LAN switch is mounted on a printed wiring board inside the first housing 4.

  Therefore, when the operator presses the finger hook 28 with the fingertip, the operation lever 27 slides in an arbitrary direction between the first position and the second position, and the switching operation of the LAN switch is executed.

  As shown in FIG. 4, the second holding portion 26 of the front panel 15 is located between the screw receiver 17 and the first through hole 19. The second holding unit 26 supports the microphone 32. The microphone 32 is an example of a component supported by the front panel 15, and includes a microphone main body 33 that obtains an electric signal from acoustic vibrations, and a cable 34 connected to the microphone main body 33.

  The microphone main body 33 has a cylindrical shape, and a convex portion 36 having a fitting hole 35 is formed on one side thereof. Since the cable 34 has flexibility, it can be pulled out or bent from the microphone main body 33 in an arbitrary direction.

  The second holding portion 26 includes a guide wall 38 into which the microphone main body 33 is fitted, a sound collecting hole 39 facing the microphone main body 33, and a fitting claw 40 corresponding to the fitting hole 35. The microphone body 33 is fitted inside the guide wall 38 with the fitting hole 35 aligned with the fitting claw 40. Thereby, the fitting claw 40 is caught by the opening end of the fitting hole 35, and the microphone body 33 is temporarily fixed to the second holding portion 26.

  Furthermore, in the present embodiment, first and second locking claws 41 a and 41 b are formed on the second holding portion 26 of the front panel 15. The first locking claw 41 a and the second locking claw 41 b face each other with the microphone main body 33 interposed therebetween, and project from the front panel 15 toward the first housing 4. The first locking claw 41a and the second locking claw 41b have different shapes.

  As shown in FIGS. 5 and 6, the first and second locking claws 41 a and 41 b support a sheet metal holder 43. The holder 43 has a square plate shape, and holds the microphone body 33 sandwiched between the second holding portion 26 and the holder 43. Thereby, the vibration of the microphone main body 33 is suppressed, and the sound collecting performance of the microphone main body 33 is enhanced.

  The holder 43 has first and second locking holes 44a and 44b. The first locking hole 44a has an opening shape with which the first locking claw 41a can be engaged, and the second locking hole 44b has an opening shape with which the second locking claw 41b can be engaged. have.

  Therefore, the holder 43 is held by the second holding portion 26 by hooking the first and second locking claws 41a and 41b in the first and second locking holes 44a and 44b, respectively. The microphone body 33 is covered from the opposite side.

  As shown in FIGS. 4 to 6, first to third locking portions 45 a, 45 b and 45 c are formed in the lower portion of the front panel 15. The first to third locking portions 45a, 45b, and 45c protrude from the lower portion of the front panel 15 toward the first housing 4, and the other end of the front panel 15 from the vicinity of the second holding portion 26. They are lined up at a distance from each other.

  The third locking portion 45c located at the other end of the front panel 15 has first to third slits 46a, 46b, 46c. The slits 46 a, 46 b, 46 c are arranged in a line at intervals in the longitudinal direction of the front panel 15.

  As shown in FIG. 5, the cable 34 of the microphone 32 is drawn obliquely downward from the microphone main body 33 held by the second holding portion 26 toward the first locking portion 45 a. The cable 34 is pulled out on the second locking portion 45b through the lower side of the first locking portion 45a and is guided below the third locking portion 45c. Further, after the cable 34 is drawn onto the third locking portion 45c through the first slit 46a, the cable 34 is guided again below the third locking portion 45c through the third slit 46c.

  Therefore, the cable 34 is bridged over the first to third locking portions 45a, 45b, 45c. In other words, the cable 34 is held by the front panel 15 along the longitudinal direction of the front panel 15.

  As shown in FIGS. 4 to 6, in the present embodiment, an arrow mark 48 is attached to the center of the holder 43. The mark 48 is formed on the holder 43 by means such as engraving or printing. The mark 48 is for displaying the direction in which the cable 34 is pulled out from the microphone main body 33. The mark 48 is adjacent to the first locking portion 45a and is directed obliquely downward so as to indicate the direction of the first locking portion 45a.

  Therefore, the cable 34 is drawn obliquely downward from the microphone main body 33 so as to follow the direction of the mark 48, and directionality is imparted to the front panel 15.

  Next, a procedure for attaching the microphone 32 to the front panel 15 will be described.

  First, as shown in FIGS. 4 and 5, the microphone body 33 is fitted into the guide wall 38 of the second holding part 26, and the fitting claw 40 is pierced through the fitting hole 35 of the convex part 36. Hook. Thereby, the microphone main body 33 is temporarily fixed to the second holding unit 26.

  Next, the holder 43 is pressed against the microphone main body 33 temporarily fixed to the second holding portion 26, and the first and second locking holes 44 a and 44 b of the holder 43 protrude from the second holding portion 26. The first and second locking claws 41a and 41b are hooked.

  As a result, the holder 43 is fixed to the second holding unit 26 and the microphone body 33 is sandwiched and held between the second holding unit 26. Therefore, the microphone body 33 is fixed at a fixed position on the front panel 15.

  The first and second locking holes 44a and 44b have opening shapes that can be engaged with the first and second locking claws 41a and 41b, respectively. The first and second locking claws 41a and 41b cannot be hooked in the second locking holes 44a and 44b. Therefore, the operator can easily know that the orientation of the holder 43 is not appropriate, and can prevent the holder 43 from being erroneously assembled.

  Next, the cable 34 led out from the microphone main body 34 is pulled out in the direction indicated by the mark 48 and guided below the first locking portion 45a. Then, the cable 34 is fixed to the front panel 15 by spanning the cable 34 so as to straddle the first to third locking portions 45a, 45b, and 45c sequentially.

  As a result, the microphone main body 33 and the cable 34 are fixed to the front panel 15, and the assembly work of the microphone 32 to the front panel 15 is completed.

  The front panel 15 is fixed to the top cover 7 after the assembly of the microphone 32 is completed. After this fixing, a connector (not shown) located at the tip of the cable 34 is connected to the printed wiring board, whereby the electrical connection work of the microphone 32 is completed.

  According to the first embodiment as described above, since the mark 48 indicating the pull-out direction of the cable 34 is formed on the holder 43 that holds the microphone body 33, the cable 34 that is flexible and has no fixed direction is placed in the direction of the mark 48. By pulling out, the cable 34 can be fixed to the first to third locking portions 45a, 45b, 45c of the front panel 15 through a predetermined regular route.

  For this reason, the orientation of the cable 34 with respect to the front panel 15 can be performed reliably and easily. Therefore, workability at the time of assembling the cable 34 to the front panel 15 is improved, work time can be shortened, and incorrect assembly of the cable 34 can be prevented.

  At the same time, the mark 48 also functions as a guide for designating the direction when the holder 43 is assembled to the second holding portion 26 of the front panel 15. Therefore, the assembling direction of the holder 43 can be easily known, which also has an advantage of contributing to improvement in workability.

  The present invention is not limited to the first embodiment described above, and can be implemented with various modifications without departing from the spirit of the invention.

  For example, FIGS. 7 and 8 disclose a second embodiment of the present invention.

  According to the second embodiment, the microphone body 33 is fixed to the second holding portion 26 of the front panel 15 by hooking the fitting claw 40 into the fitting hole 35.

  Further, the microphone main body 33 has a flat surface 33 a located on the opposite side of the front panel 15. An arrow mark 48 indicating the direction in which the cable 34 is pulled out from the microphone body 33 is attached to the center of the flat surface 33a. The mark 48 is directed obliquely downward so as to indicate the direction of the first locking portion 45a when the microphone body 33 is fixed to the second holding portion 26. Therefore, the cable 34 is drawn from the microphone body 33 along the direction of the mark 48.

  According to such a configuration, the cable 34 is pulled out in the direction of the mark 48 with the cable 34 being flexible and whose direction is not determined, whereby the first to third locking portions of the front panel 15 are passed through a predetermined regular route. It can be fixed to 45a, 45b, 45c.

  Therefore, as in the first embodiment, the orientation of the cable 34 with respect to the front panel 15 can be performed reliably and easily, and workability is improved.

The third mark 51c is located on the upper surface of the third locking portion 45c. The third mark 51c points in the same direction as the second mark 51b.

  As shown in FIG. 10, when the microphone main body 33 is fixed to the second holding portion 26 of the front panel 15 via the holder 43, a first mark that is obliquely downward is directly below the connection portion between the microphone main body 33 and the cable 34. 51a is located. Therefore, by pulling out the cable 34 led out from the microphone body 33 in the direction indicated by the first mark 51a, the cable 34 can be guided below the first locking portion 45a.

  The cable 34 guided below the first locking portion 45a is guided onto the second locking portion 45b through the lower side of the first locking portion 45a. Since the second mark 51b directed to the third locking portion 45c is located on the upper surface of the second locking portion 45b, the cable 34 is connected to the second locking portion along the direction indicated by the second mark 51b. It can be guided from the upper surface of the stopper 45b to the bottom of the third locking part 45c.

  Further, the cable 34 guided below the third locking portion 45c is guided onto the third locking portion 45c through the first slit 46a. Since the third mark 51c is located on the upper surface of the third locking portion 45c, the cable 34 can be guided to the third slit 46c along the direction indicated by the third mark 51c.

  According to such a configuration, the cable 34 can be determined in advance by guiding the flexible cable 34 whose direction is not determined in order along the directions indicated by the first to third marks 51a, 51b, 51c. Further, it can be bridged to the first to third locking portions 45a, 45b, 45c of the front panel 15 through a regular route.

  Therefore, as in the first embodiment, the orientation of the cable 34 with respect to the front panel 15 can be performed reliably and easily, and workability is improved.

  FIG. 11 discloses a fourth embodiment of the present invention.
