  According to the second aspect, the operation of positioning a large number of female threaded bodies on top of the male threaded body is further facilitated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  Fig.1 (a) is a partial rear view of the electronic device manufactured using the female screw body mounting | wearing assistance jig | tool which concerns on one embodiment of this invention. The electronic device 10 is configured as, for example, a mixer device, and a large number of shaft portions 11 that are male screwed bodies are arranged on the rear panel surface 10a, for example, two-dimensionally.

  FIG. 1B is a side view of one shaft portion 11. The shaft portion 11 is a jack terminal having a male screw 11a formed on the outer diameter portion, and an insertion hole 11h (described later in FIG. 4A) for voice input / output or the like is formed in the inner diameter portion. In order to stably fix the shaft portion 11 to the panel surface 10a, a nut 12 having a female screw 12a formed on its inner diameter is screwed into the male screw 11a. Usually, one nut 12 is manually screwed into each shaft portion 11, but in this embodiment, this operation is subsidized using a jig JG described later.

  The target electronic device is not limited to the mixer device, and may be any electronic device in which a plurality of male threaded shaft portions to which a nut is to be screwed project from the panel surface. Further, the panel surface on which a large number of shaft portions are provided is not limited to the back surface of the device. Further, the function of the shaft portion is not limited and is not limited to the jack terminal.

  2A and 2B are plan views of the jig JG. 3A and 3B are cross-sectional views taken along the line AA in FIG. 2A, and FIG. 3C is a cross-sectional view taken along the line BB in FIG. 2B. FIG. 4A is a cross-sectional view of one shaft portion 11 to which the nut 12 is screwed. 4B to 4D will be described later. In FIGS. 2A and 2B, only a part of all the nuts 12 to be attached is shown in order to make the drawings easy to see.

  Although the panel surface 10a is the back surface, since the screwing operation is normally performed with the shaft portion 11 protruding upward, the projecting direction of the shaft portion 11 from the panel surface 10a is hereinafter referred to as the vertical direction. Called the top. 2A is the rear / front side of the jig JG, and the upper / lower side of FIG. 2A and FIG. 3A is the upper / lower side of the jig JG. Lower, left / right.

  As shown in FIG. 4A, from the back side of the panel surface 10a, the portion of the male screw 11a of the shaft portion 11 is inserted into the front side through the panel hole 11ah, and the shaft portion main body 11c and the flange portion 11d of the shaft portion 11 are connected to the panel. It is located on the back side of the surface 10a. The nut 12 is screwed into the male screw 11a from the front side, and the flange portion 11d is in contact with the back side of the panel surface 10a. Terminals T1, T2, and T3 are provided at the lower portion of the shaft body 11c. When a plug (not shown) is inserted into the insertion hole 11h, the three conductors of the plug come into contact with the terminals T1, T2, and T3.

  As shown in FIGS. 2A and 3A, the jig JG is composed of a lower plate 20 and an upper plate 30 that are separate from each other and are rectangular in plan view. The lower plate 20 is integrally formed of a light-transmitting resin or the like, and has a frame portion 24 that protrudes upward in front, rear, left, and right, and a thin plate-like portion 25 is formed inside the frame portion 24. Leg portions 23 project downward from four spaced apart locations on the lower surface of the lower plate 20. The protruding height of the leg portion 23 is substantially the same as the protruding height of the shaft portion 11.

  Guide pins 22 project upwardly at two locations on the left and right of the rear portion of the plate-like portion 25 of the lower plate 20. A plurality of lower insertion holes 21 are formed in the plate-like portion 25. Although only a part of the lower insertion holes 21 is shown in FIG. 2A, the arrangement of the lower insertion holes 21 in plan view is the same as the arrangement in plan view of the shaft portion 11 to which the nut 12 is screwed. Match. Here, the shaft portion 11 to which the nut 12 is to be screwed does not have to be all of the shaft portion 11 provided on the panel surface 10a, but may be a part thereof.

  Each lower insertion hole 21 is circular and has a diameter slightly larger than the maximum outer dimension of the nut 12 which is a hexagon, so that the nut 12 can pass therethrough. The depth dimension of the lower insertion hole 21 depends on the thickness of the lower plate 20 and is substantially the same as the thickness of the nut 12.

  On the other hand, the upper plate 30 is integrally formed in a thin plate shape with a light transmissive resin or the like. At the time of substituting for the nut 12, the upper plate 30 is stacked on the upper surface 20 e of the lower plate 20. The length in the front-rear direction of the upper plate 30 is slightly smaller than the inner dimension in the front-rear direction of the frame portion 24 of the lower plate 20. Further, the length in the left-right direction of the upper plate 30 is shorter by the diameter of the lower insertion hole 21 than the inner dimension in the left-right direction of the frame portion 24 of the lower plate 20.

  Therefore, when the upper plate 30 is fitted in the frame portion 24 of the lower plate 20, the front and rear end surfaces 30c and 30d of the upper plate 30 lightly contact the front and rear inner surfaces 20c and 20d of the frame portion 24. Or a slight gap is formed. In addition, either or both of the left and right end surfaces 30a and 30b of the upper plate 30 are separated from the left and right inner side surfaces 20a and 20b of the frame portion 24.

  When the upper plate 30 is fitted in the frame portion 24 of the lower plate 20, the upper plate 30 in the horizontal direction is slid by the sliding contact between the inner surfaces 20 c and 20 d of the lower plate 20 and the end surfaces 30 c and 30 d of the upper plate 30. Movement in the front-rear direction is restricted, and only relative sliding movement in the left-right direction is allowed. The slide movement limit position in the left-right direction with respect to the lower plate 20 of the upper plate 30 is regulated by the contact between the inner surface 20a and the end surface 30a and the contact between the inner surface 20b and the end surface 30b.

  Further, elongated holes 32 that are long in the left-right direction through which the guide pins 22 pass are formed in two places on the left and right of the rear portion of the upper plate 30. Even with the relationship between the guide pins 22 and the long holes 32, the upper plate 30 is only allowed to slide in the left-right direction with respect to the lower plate 20. 2A, 3A, and 3B show a state in which the upper plate 30 is in the leftward movement limit position. FIGS. 2B and 3C show that the upper plate 30 is It shows a state at the movement limit position in the right direction.

  When the inner surface 20b contacts the end surface 30b, the left end of each elongated hole 32 contacts the corresponding guide pin 22 (see FIGS. 2A, 3A, and 3B). Moreover, when the inner surface 20a and the end surface 30a contact | abut, the right end of each long hole 32 contact | abuts to the corresponding guide pin 22 (refer FIG.2 (b), FIG.3 (c)). Any mechanism other than these may be employed as long as it restricts the movement of the upper plate 30 in the front-rear direction relative to the lower plate 20 and defines the movement range in the left-right direction. Further, as such a mechanism, in the present embodiment, a mechanism constituted by the inner side surfaces 20a to 20d and the end faces 30a to 30d and a mechanism constituted by the long hole 32 and the guide pin 22 are provided in an overlapped manner. Only one of these mechanisms may be employed in each of the left and right directions.

  A plurality of upper insertion holes 31 are formed in the upper plate 30 corresponding to the lower insertion holes 21 of the lower plate 20. Similar to the lower insertion hole 21, the arrangement of the upper insertion holes 31 in a plan view matches the arrangement in the plan view of the shaft portion 11 to which the nut 12 is to be screwed. The shape and size of each upper insertion hole 31 are the same as those of the lower insertion hole 21, and the depth dimension of the upper insertion hole 31 depends on the thickness of the upper plate 30 and is substantially the same as the thickness of the nut 12.

  As shown in FIGS. 2A, 3A, and 3B, when the upper plate 30 is positioned at the slide movement limit position in the right direction with respect to the lower plate 20, the lower plate 20 The position of the lower insertion hole 21 and the upper insertion hole 31 of the upper plate 30 is in a “mismatched state”. On the other hand, as shown in FIGS. 2B and 3C, the positions of the lower insertion hole 21 and the upper insertion hole 31 coincide with each other when the upper plate 30 is positioned at the slide movement limit position in the left direction. "Matching state".

  In such a configuration, in the step of screwing and attaching one nut 12 to each of the plurality of shaft portions 11, particularly the operation until the plurality of nuts 12 are collectively positioned at the position of the tip 11 b of each shaft portion 11. , Using the jig JG as follows.

  First, as shown in FIGS. 2 (a) and 3 (a), the operator brings the four legs 23 of the lower plate 20 into contact with the panel surface 10a, and the nut 12 in a plan view. The position of the corresponding lower insertion hole 21 of the lower plate 20 is aligned with the position of the shaft portion 11 to be mounted. This operation may be performed with the upper plate 30 placed on the lower plate 20. Since the lower plate 20 and the upper plate 30 are light-transmitting, it is easy to perform alignment visually.

  When the leg portion 23 comes into contact with the panel surface 10a, the lower surface of the lower plate 20 and the tip 11b of each shaft portion 11 are substantially flush with each other, but the vertical relationship between the two is not strictly limited. A physical positioning mechanism (such as a hole and a pin) for the shaft portion 11 of the lower plate 20 may be provided between the panel surface 10 a and the lower plate 20. If such a positioning mechanism is provided, the lower plate 20 and the upper plate 30 do not need to be light transmissive, and may be made of metal or the like.

  Next, when the upper plate 30 is not stacked on the lower plate 20, the upper plate 30 is stacked on the upper surface 20 e of the lower plate 20, and the upper plate 30 is placed on the right side of the lower plate 20. Position it at the slide limit position. In this state, the nuts 12 are fitted into all the upper insertion holes 31 of the upper plate 30 (all the upper insertion holes 31 corresponding to the shaft portion 11 to be screwed).

  At this time, the nuts 12 may be put one by one, but a sufficient number of nuts 12 are naturally fitted into the upper insertion holes 31 by spreading a sufficient number on the upper plate 30 and spreading it by hand. Easy to work. When the nuts 12 are fitted in all the upper insertion holes 31, the excess nuts 12 may be removed. In particular, the depth of each upper insertion hole 31 is approximately the same as the thickness of the nut 12, and the upper surface of the nut 12 fitted in the upper insertion hole 31 is flush with the upper surface of the upper plate 30. Accordingly, the nut 12 is not caught when the nut 12 is horizontally moved by hand or the like on the upper surface of the upper plate 30, and the nut 12 is easily fitted into the non-inserted upper insertion hole 31.

  The nut 12 fitted in the upper insertion hole 31 rides on the upper surface 20e of the lower plate 20, is held in the upper insertion hole 31, and is supported by the upper surface 20e.

  Next, the upper plate 30 is slid to the left and is positioned at the left slide movement limit position as shown in FIGS. 2 (b) and 3 (c). The nut 12 is also carried by the upper insertion hole 31 and moves together. The upper plate 30 may be provided with a grip portion on the upper surface or the like for operation during slide movement. When the upper plate 30 reaches the left slide movement limit position, the shaft portion 11, the lower insertion hole 21, and the upper insertion hole 31 are concentrically aligned.

  Then, each nut 12 supported on the upper surface 20e is dropped downward from the upper insertion hole 31, and naturally falls in a horizontal posture through the corresponding lower insertion hole 21, and onto the corresponding tip 11b of the shaft portion 11. It will be in the state (refer FIG.2 (b), FIG.3 (c)). These operations occur simultaneously in all the nuts 12. At this time, since most of each part of each nut 12 remains in the lower insertion hole 21, a horizontal posture is maintained.

  When the nut 12 is positioned at the tip 11b of the shaft portion 11, the jig JG is removed upward. Then, each nut 12 is rotated by hand work etc. and screwed together with the shaft part 11.

  According to the present embodiment, when the upper plate 30 is positioned at the right slide movement limit position and the nut 12 is fitted into the upper insertion hole 31, the nut 12 is in the same planar arrangement as the shaft portion 11. It is supported on the upper surface 20 e of the lower plate 20. Then, when the upper plate 30 is slid to the left slide movement limit position, all the nuts 12 are automatically positioned collectively at the position of the tip 11b of each shaft portion 11 through the lower insertion hole 21. Therefore, it is possible to make a large number of nuts 12 in a state immediately before screwing at the same time, and the nut mounting operation can be facilitated.

  In particular, the sliding movement limit position on the left side of the upper plate 30 is regulated by the contact between the inner surface 20a of the lower plate 20 and the end surface 30a of the upper plate 30, and the lower insertion hole 21 and the upper insertion hole 31 are formed. Since they coincide with each other, it is easy to collectively guide the numerous nuts 12 held in the upper insertion hole 31 to the tip 11b of the shaft portion 11.

  In addition, the number and arrangement | positioning aspect of many axial parts 11 used as the screwing object of the nut 12 in the panel surface 10a are not ask | required. In particular, the lower insertion hole 21 and the upper insertion hole 31 of the jig JG are provided corresponding to only the shaft portion 11 that is actually to be screwed, or the lower insertion hole 21 corresponding to the screwing target. Only the upper insertion hole 31 may be actually used.

  The nut 12 has a hexagonal shape in plan view, and the lower insertion hole 21 and the upper insertion hole 31 are circular. However, the present invention is not limited thereto. The outer shape of the nut 12 is not limited, and the lower insertion hole 21 and the upper insertion hole 31 may be any shape that allows the nut 12 to pass through in a horizontal state. However, a shape that allows penetration, regardless of the direction of the rotation direction of the nut 12, such as a circle, is more advantageous.

  Note that the positioning of the lower insertion hole 21 and the upper insertion hole 31 is not provided without any positioning mechanism (inner surface 20a, end surface 30a, etc.) that restricts the relative position of the upper plate 30 in the horizontal direction with respect to the lower plate 20. Even if the configuration is such that the alignment is performed visually, it is simpler than the conventional work of mounting one by one.

  In the present embodiment, the nut 12 is exemplified as the female threaded body. However, the present invention is not limited to this, and any threaded body with a female thread may be used as illustrated in FIGS. 4B and 4C. Further, as illustrated in FIGS. 4B and 4C, the female screw of the present invention is used for the screwing assistance of two or more types of female screwed members screwed to one or two shaft portions 11. A combined mounting aid jig may be applied.

  4B and 4C are cross-sectional views showing modifications of the female threaded body and the male threaded body. First, the shaft portion 11 shown in FIG. 4B has the terminals T1, T2, and T3 abolished with respect to the configuration shown in FIG. 4A, and a switch body SW and a knob shaft 51 are provided. However, other configurations are the same. The switch body SW is integrally provided at a lower portion of the shaft portion body 11c of the shaft portion 11, and a knob shaft 51 projects from the switch body SW upward through the insertion hole 11h. A male screw 51 a is formed on the upper part of the knob shaft 51. Since it is easy to disengage in press fitting, the female screw 50 a of the knob 50 is screwed into the male screw 51 a and the knob 50 is attached to the knob shaft 51.

  The switch body SW has a structure that is turned on / off by a push operation. Each time the knob portion 50 is pressed, the knob shaft 51 is stabilized at a predetermined position below or above. FIG. 4B shows a push-off state. When the knob portion 50 is pressed once from this state, the knob shaft 51 is turned on in a lowered state. Press again to return to the original off state.

  In this example, after the nut 12 is screwed to the shaft portion 11, the knob portion 50 is screwed to the knob shaft 51. When the nut 12 is screwed into the shaft portion 11, the knob shaft 51 performs a mounting guide function when the nut 12 falls from the lower plate 20 to the shaft portion 11. When the knob portion 50 is positioned at the tip 51b of the knob shaft 51 to assist the screwing, a set of plates similar to the lower plate 20 and the upper plate 30 may be created and used. In the set, naturally, the size of the lower insertion hole 21 and the upper insertion hole 31 needs to be matched to the knob portion 50.

  In the example shown in FIG. 4C, the shaft portion main body 11c of the shaft portion 11 is formed in a bottomed cylindrical shape, and the leg portion of the LED 53 is attached to the bottom portion 11e through the insertion hole 11h. The structure of the other part of the axial part 11 is the same as that of the example of Fig.4 (a). The male screw 11a is not only screwed with the nut 12, but is further fitted with a transparent LED cap 52. In substituting the LED cap 52 to the shaft portion 11, a plate set similar to the lower plate 20 and the upper plate 30 may be created and used. In the set, naturally, the size of the lower insertion hole 21 and the upper insertion hole 31 needs to match the LED cap 52.

  In the example of FIG. 4B, the nut 12 and the knob portion 50 correspond to the female threaded body, and the shaft portion 11 and the knob shaft 51 correspond to the male threaded body. In the example of FIG. 4C, the nut 12 and the LED cap 52 correspond to the female threaded body, and the shaft portion 11 corresponds to the male threaded body.

  In the example of FIGS. 4B and 4C, when two types of female threaded bodies are screwed one after another, a dedicated jig JG is created for each of them, and in the case of performing the mounting support, FIG. As shown in d). That is, first, the first female screwed body (nut 12) is mounted using the first set of the lower plate 20A and the upper plate 30A, and then the second set of the second set of the lower plate 20B and the upper plate 30B. A female threaded body (knob portion 50, LED cap 52) is attached.
