Japanese Patent Laid-Open No. 2007-12800

  Conventionally, since the nut member screwed into the left and right bolt parts (male screws) is fastened and fixed, it is necessary to repeat the fixing operation by tightening the nut member twice. Further, if only one nut member of the two nut members is excessively tightened and the tightening force of the two nut members is different, the nut member may not be sufficiently fixed and the nut member may be loosened.

  An object of the present invention is to provide an electronic device fixing structure in which the electronic device can be fixed to the mast only by tightening one nut member in the structure as described above.

According to the first aspect of the present invention, a holding portion is formed in an equipment casing of an electronic device, a mast fixing tool is held by the holding portion, and the mast fixing tool is fixed to the mast via the mast fixing tool. A fixing structure for an electronic device including a pressing member and a nut member, wherein the bolt member includes a locking bar portion in which a locking recess capable of locking the pressing member is formed, and the locking bar portion The bolts have a threaded rod portion that extends in parallel with the nut member and a connecting rod portion that connects the base ends thereof, and the bolts with the connecting rod portion as a rotation axis. While the member is rotatably held by the holding portion, the pressing member has a notch in which the locking rod portion is removably engaged with each end portion and an insertion portion through which the screw rod portion is inserted. Each of the locking recesses is formed in front At least provided at a position corresponding to the diameter of the mast on which the electronic device is secured, engaging said threaded rod portion, the notch of the pressing member and the rotating direction of the nut member for fastening to the locking recess A screw is provided so that the direction to be engaged is coincident, and the rotation direction of the nut member for tightening and the direction in which the notch of the pressing member is engaged with the locking recess are characterized in that To do. Here, the presser fitting includes, in addition to the one described in claim 4 to be described later, one in which the metal fitting body is bent in a U-shape as described in, for example, JP-A-2007-12800. It is.

  In this way, in a state where the mast is sandwiched between the holding portion of the device casing of the electronic device and the pressing member, one end of the pressing member is positioned at the position corresponding to the diameter of the mast by the locking recess of the locking rod portion. Since the nut member is screwed into the threaded rod portion, the other end portion of the pressing member is moved in the direction of sandwiching the mast and is fixed. At this time, since one end portion of the pressing member is locked by the locking recess of the locking rod portion, the mast is fixed between the holding portion of the device casing and the pressing member without moving. The

  Moreover, since one nut member is fastened and fixed, the working time can be shortened compared to the conventional case in which two nut members are fastened and fixed. In addition, when two nut members are used as in the prior art, if only one nut member is excessively tightened and the tightening force of the two nut members is different, the nut member is not sufficiently fixed and the nut member loosens. However, such a problem is also avoided.

  In addition, the screw rod portion is provided with a screw so as to be tightened by rotating the nut member on the side where the locking rod portion is located, and the rotation direction of the nut member for tightening and the presser Since the direction in which the notch of the member is engaged with the locking recess coincides, there is a possibility that the engagement between the notch of the pressing member and the locking recess is released when the nut member is rotated and tightened. From this point, the working time can be shortened, which is advantageous in improving workability.

  According to a second aspect of the present invention, the locking concave portion may be provided between two projecting portions that project outward from the outer peripheral surface of the bar-shaped portion having a circular cross section.

  If it does in this way, the structure of the said latching recessed part is simple, and it can control easily that the said pressing member moves to the front end side of the said latching bar part. In particular, when tightening with a nut member, there is no possibility that the pressing member moves to the distal end side or the proximal end side of the locking rod portion, and it can be fixed with good workability.

  In this case, as described in claim 3, the protruding portion is formed by crushing a part of the locking rod portion and protruding outward, and a plurality of types of masts to which the electronic device is fixed. It can be provided at regular intervals so as to include positions corresponding to the diameter.

  If it does in this way, a latching recessed part can be easily formed using a protrusion part. Moreover, an electronic device can be fixed to a plurality of types of masts having different diameters. Since the protruding portions are provided at regular intervals, processing is also easy.

According to a fourth aspect of the present invention, the pressing member has a U-shaped cross section, and a rectangular plate-shaped main body portion, and both side edges of the main body portion sandwiching a line connecting the notch and the insertion portion. It is desirable to have a rectangular plate-like side plate portion that is provided and extends in parallel.

  In this way, when the pressing member is applied to the mast, the rectangular plate-shaped main body portion can be easily disposed substantially parallel to the device casing, and the pressing member can be attached without being inclined with respect to the device casing.

Further, in the invention of claim 5, a holding part is formed in an equipment casing of an electronic device, a mast fixing tool is held in the holding part, and the mast fixing tool is fixed to the mast via the mast fixing tool. A fixing structure of an electronic device including a bolt member, a pressing member, and a nut member, wherein the bolt member includes a locking bar portion in which a locking recess capable of locking the pressing member is formed, and the locking It has a U-shape having a threaded rod portion extending in parallel with the rod portion and screwed with the nut member, and a coupling rod portion for connecting the base ends thereof to each other, and the coupling rod portion as a rotating shaft. While the bolt member is rotatably held by the holding portion, the pressing member is inserted through the notch and the screw rod portion through which the locking rod portion is removably engaged with each end portion. Each part is formed and the locking recess At least provided at a position corresponding to the diameter of the mast, wherein the electronic device is fixed, the pressing member is a U-shaped section, and a rectangular plate-shaped main body, of the body portion, O and lack the cut A rectangular plate-like side plate portion provided on both side edges sandwiching a line connecting the insertion portions and extending in parallel is characterized.

  Also in this case, when the pressing member is applied to the mast, the rectangular plate-shaped main body portion can be easily disposed substantially parallel to the device casing, and the pressing member can be attached without being inclined with respect to the device casing.

  In these cases, as described in claim 6, the notch is formed long in a member longitudinal direction of the pressing member, and an insertion opening through which the locking bar portion is inserted. A holding portion in which the rod portion is located, and a communication portion that communicates the insertion opening and the holding portion, and the insertion portion is an elongated hole that is long in the member longitudinal direction of the pressing member, and the insertion of the notch It can be set as the structure which has a 1st hole part, a 2nd hole part, and a communicating hole part by the positional relationship corresponding to an opening part, a holding | maintenance part, and a communicating part.

  In this way, the insertion opening portion of the notch through which the locking rod portion is inserted and the holding portion where the locking rod portion is held in the attached state are shifted from each other in the longitudinal direction of the pressing member. The locking rod portion is positioned on the holding portion, and the nut member is tightened to restrict the movement of the locking rod portion in the direction perpendicular to the member longitudinal direction of the holding rod portion (notch). The nut member can be tightened in a state in which the locking rod portion is difficult to come off.

  In this case, as described in claim 7, the notch holding portion has an extended hole portion that extends to a side opposite to the side where the insertion opening portion opens, and the second hole portion of the insertion portion. It is desirable to have a hole portion corresponding to the extended hole portion.

  According to this configuration, the nut member is tightened in a state in which the holding member restricts not only the direction of the pressing member of the locking bar portion perpendicular to the member longitudinal direction but also the movement of the pressing member in the member longitudinal direction. Can do.

  Since the present invention is fixed using one nut member as described above, the working time can be shortened and screw loosening can be prevented as compared with the conventional case of fixing using two nut members. This is also advantageous.

  In particular, the screw rod portion of the bolt member is provided with a screw so that it can be tightened by rotating the nut member on the side where the locking rod portion is located, and the rotation direction of the nut member for tightening and the notch of the pressing member Since the direction of engagement with the locking recess coincides with that of the locking recess, there is no possibility that the notch of the pressing member and the locking recess are released when the nut member is rotated and tightened. Therefore, the working time can be shortened.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description, the side on which the main body portion 4 is provided will be described as the front side, and the side on which the attachment portions 6A and 6B are provided will be described as the bottom surface side.

  As shown in FIGS. 1 to 4, the device casing 3 in the device main body 2 of the electronic device 1 (for example, a two-distributor) projects integrally with a rectangular parallelepiped main body portion 4 and the back side of the main body portion 4. A holding portion 5 provided with an outer peripheral portion positioned inward from the outer peripheral portion of the main body portion 4 is provided. A mast fixing bracket 11 for attaching the electronic device 1 to the mast M is detachably held by the holding portion 5. At the lower part of the main body 4, attachment parts 6 A and 6 B are provided so that the electronic device 1 can be attached not only to an outdoor mast but also to an attachment surface such as a wall surface. The attachment parts 6 A and 6 B include A mounting screw 15 for mounting the electronic device is provided.

  In the state shown in FIGS. 1 and 2, the mast fixing bracket 11 is in the storage state, and when the electronic device 1 is attached to the mast M, the storage of the mast fixing bracket 11 is released, as shown in FIGS. The electronic device 1 is fixed by fixing the device casing 3 to the mast M via the mast fixing bracket 11. A circuit unit (not shown) for processing a high-frequency signal is accommodated in the main body 4 of the device casing 3, and an F-type connector 8 (connector) for inputting and outputting signals on the lower surface of the main body 4. Are provided so as to protrude downward.

  As shown in FIG. 9A, the mast fixing bracket 11 includes a bolt member 12, a pressing bracket 13 (pressing member), and one wing nut 14 (nut member).

  As shown in FIG. 9B, the bolt member 12 is formed by bending a wire rod into a U-shape, and includes a locking rod portion 12A and a screw rod portion 12B extending in parallel with the locking rod portion 12A. And a connecting rod portion 12C that connects the base ends of the locking rod portion 12A and the screw rod portion 12B to each other, and is held rotatably with respect to the holding portion 5 with the connecting rod portion 12C as a rotation axis. . The locking bar portion 12A is regularly provided with a plurality of locking recesses 12Aa, 12Aa,... Capable of locking one end of the presser fitting 13 at regular intervals. Each locking recess 12Aa has a function of restricting the pressing metal 13 from moving to the distal end side or the proximal end side of the locking rod part 12A in a state where the notch 13a of the pressing metal 13 is engaged. In addition, one latching recessed part 12Aa is provided between two protrusion part 12Ab which protrudes outward from the outer peripheral surface of a rod-shaped part with a circular cross section. The projecting portion 12Ab is formed by crushing a part of the locking rod portion 12A and projecting outward, and positions corresponding to the diameters of a plurality of types of masts to which the device casing 3 (electronic device) is fixed. It is provided at regular intervals so as to include. That is, since the holding portion 5 is formed with a recess 5a into which the mast M is fitted, as shown in FIG. 7, when the diameter of the mast M is L, for example, the locking recess 12Aa corresponding to the diameter L is selected. When the notch 13a is engaged, the mast M can be sandwiched and fixed between the recess 5a and the pressing metal 13. This is because the locking recess 12Aa is provided at least at a position corresponding to the diameter of the mast M to which the device casing 3 (electronic device) is fixed.

  The holding metal fitting 13 has a U-shaped cross section by a rectangular plate-like metal fitting body 13A (main body portion) and two rectangular plate-like side plate portions 13B and 13C extending in parallel in the same direction on both upper and lower sides of the metal fitting main body 13A. Is formed. The widths of the side plate portions 13B and 13C are smaller than the height (width) of the metal fitting body 13A. A notch 13a extending to one side plate portion 13C and detachably engaging with the locking rod portion 12A is provided on one end side of the presser fitting 13 (metal body 13A) on the other end side. Are respectively formed with insertion holes 13b (insertion portions) through which the screw rod portions 12B are inserted. The wing nut 14 is screwed into the male screw 12Ba of the screw rod portion 12B protruding through the insertion hole 13b. Moreover, recessed part 13Ba and 13Ca which contact the outer peripheral surface of the mast M are formed in the side-plate parts 13B and 13C. The metal fitting body 13A has a recess 13c formed at the center, and the required rigidity is ensured.

  Therefore, when the presser fitting 13 (side plate portions 13B, 13C) is applied to the mast M, the rectangular plate-like metal fitting body 13A can be easily arranged almost in parallel with the device casing 3, and the wing nut 14 can be easily tightened. The presser fitting 13 can be attached without being inclined with respect to the device casing 3. In other words, in the case of a conventional bracket-shaped holding metal fitting (see, for example, Japanese Patent Application Laid-Open No. 2007-12800), the portion on the locking rod portion 12A side of the dog-shaped portion hits the mast first and becomes large. In some cases, the wing nut 14 cannot be fully tightened, and the presser fitting can be attached so as to be inclined in the final mounting state. However, in the case of the pressing metal 13 described above, such a situation can be avoided.

  The screw rod portion 12B is formed with a male screw 12Ba so as to be tightened by rotating the wing nut 14 on the side where the locking rod portion 12A is located when being attached to the mast. The rotating direction R1 that rotates and the direction R2 in which the notch 13a of the presser fitting 13 engages with the locking recess 12Aa coincide with each other (see FIGS. 5 and 14D). The rotating direction of the wing nut 14 for tightening and the direction in which the notch 13a of the presser fitting 13 is engaged with the locking recess 12Aa are the same. Specifically, the screw rod portion 12B is disposed on the left side and the locking rod portion 12A is disposed on the right side toward the holding portion 5, and the male screw 12Ba of the screw rod portion 12B is a right screw.

  Therefore, in a state where the notch 13a is engaged with any one of the locking recesses 12Aa, when the wing nut 14 is rotated and tightened, the pressing metal 13 is locked by the locking recess 12Aa and the protruding portions 12Ab on both sides thereof. Since it is prevented that the rod portion 12A moves or disengages in the axial direction, it can be fixed without the operator pressing the pressing metal 13 by hand. The upper end portion 5e of the holding portion 5 is formed as a flat surface (holding surface), and the lower end portion is formed as a concave portion 5b on the main body portion 4 side and a receiving portion 5c outside thereof. The receiving portion 5c is further formed with an engaging recess 5d in which the connecting rod portion 12C of the bolt member 12 is engaged when stored.

  Further, the main body portion 4 and the attachment portions 6A and 6B are connected via the connection portions 7A and 7B, and the through-holes 9A and 9B are provided between the attachment portions 6A and 6B and the holding portion 5 by the connection portions 7A and 7B. Is formed. On the upper side of the connecting portions 7A and 7B located on the back side of the through holes 9A and 9B, in the vicinity of the base end portion of the locking rod portion 12A and the screw rod portion 12B of the bolt member 12 in the attached state to the mast M Are engaged, and engaging recesses 7Aa and 7Ba for horizontally supporting both rod portions 12A and 12B are formed.

  Accordingly, the bolt member 12 can be attached to the holding portion 5 simply by inserting the locking rod portion 12A and the screw rod portion 12B of the bolt member 12 from the lower side into the through holes 9A and 9B. Is easy to install. As shown in FIGS. 1, 2, and 10 to 12, the bolt member 12 has the connecting rod portion 12 </ b> C engaged with the engaging recess 5 d of the receiving portion 5 c, and the presser fitting 13 of the holding portion 5. As shown in FIGS. 4 to 8 and 13, the connecting rod portion 12C comes into contact with the support portion 5f in the concave portion 5b and is locked on the storage state that is placed on the upper end portion 5e and fixed by the wing nut 14. The base end of the portion 12A and the screw rod portion 12B can be easily switched between the mast mounting state where the base end portion engages with the engaging recesses 7Aa and 7Ba of the connecting portions 7A and 7B. As described above, when the locking rod portion 12A and the screw rod portion 12B of the bolt member 12 are horizontally supported, the engagement recess portions 7Aa and 7Ba are engaged with the locking rod portion 12A and the screw rod portion 12B of the bolt member 12. In order to engage the base end portion, the bolt member 12 is allowed to rotate about the connecting rod portion 12C as the rotation axis in a state where the connecting rod portion 12C is in contact with the support portion 5f in the recess 5b. ing.

  Next, a procedure for fixing the electronic device 1 to the mast M using the above structure will be described with reference to FIGS.

  Since it is in the retracted state before attachment, first, as shown in FIG. 14A, the wing nut 14 is loosened, the engagement between the presser fitting 13 and the upper end portion 5e of the holding portion 5 is released, and the bolt member 12 Tilt.

  Then, the bolt member 12 is rotated in the recess 5b with the connecting rod portion 12C as the rotation axis, and the vicinity of the base end portion of the locking rod portion 12A and the screw rod portion 12B of the bolt member 12 is set to the engagement recesses 7Aa and 7Ba. As shown in FIG. 14B, the two rod portions 12A and 12B are supported in a horizontal state. At this time, the presser fitting 13 is supported in a state of hanging from the screw rod portion 12B.

  The bolt member 12 is engaged with the mast M so that the mast M is positioned between the locking rod portion 12A of the bolt member 12 and the screw rod portion 12B. The outer peripheral surface of the mast M is brought into contact with the recess 5 a of the holding unit 5.

  Thereafter, as shown in FIGS. 14C and 14D, the presser fitting 13 is rotated with the screw rod portion 12B as the rotation axis, and the notch 13a is fixed to the locking rod portion 12A with the diameter of the mast M to be fixed. (See FIG. 14 (e)). At this time, since the presser fitting 13 can be freely moved on the screw rod portion 12B, the engagement between the notch 13a and the locking recess 12Aa can be performed smoothly. That is, the width W in the axial direction of each locking recess 12Aa is set to a width that allows easy engagement with the notch 13a (see FIG. 8).

  Thereafter, the wing nut 14 is fastened to the male screw 12Ba of the screw rod portion 12B, and the mast M can be sandwiched and fixed between the presser fitting 13 and the holding portion 5. At this time, the holding metal 13 does not move in the axial direction due to the engagement relationship between the notch 13a, the locking recess 12Aa, and the projecting portions 12Ab on both sides thereof, and of course the left side toward the holding portion 5 Since the screw rod portion 12B is disposed on the right side and the locking rod portion 12A is disposed on the right side, and the screw of the screw rod portion 12B is a right-hand screw. The force acts, and the rotational force of the wing nut 14 rotates the presser fitting 13 in the direction in which the notch 13a engages with the locking recess 12Aa. Therefore, when tightening with the wing nut 14, the notch 13a does not come off from the locking rod portion 12A.

  Thus, since it can fix only by tightening one wing nut 14, not only can the number of parts be reduced, but the tightening work of the wing nut 14 is half of the conventional work of tightening two wing nuts. This reduces the burden on the operator and shortens the work time.

  In addition, even if only one wing nut 14 is fixed in this way, the notch 13a engages with the locking recess 12Aa of the locking rod portion 12A, and the male of the screw rod portion 12B passing through the insertion hole 13b. Since the wing nut 14 is screwed and tightened to the screw 12Ba, the presser fitting 13 does not come off from the bolt member 12.

  In the above-described embodiment, the presser fitting 13 having the notch 13a at one end and the insertion hole 13b (round hole) at the other end is used. It is also possible to use the presser fitting 23 shown in FIGS. The presser fitting 23 has a rectangular plate-like metal fitting body 23A (main body portion) with a raised central portion, and side plate portions 23B and 23C extending in parallel to the direction opposite to the protruding direction above and below the metal fitting body 23A. . And in the presser fitting 23, the notch 23a formed in one edge part of the metal fitting body 23A is formed so that it may be long in the metal fitting longitudinal direction of the metal fitting 23 (metal fitting body 23A), and may extend to the other edge part side. ing. The notch 23a communicates with the insertion opening 23aa into which the locking rod portion 12A is inserted, the holding portion 23ab where the locking rod portion 12A is positioned in a fixed state to the mast M, the insertion opening 23aa and the holding portion 23ab. And a communication portion 23ac. Note that, in the portion of the cutout 23a where the insertion opening 23aa is formed, the side plate portion 23C is partially cut away, and the length of the presser fitting 23 in the metal fitting longitudinal direction is shorter than that of the side plate portion 23B. On the other hand, the insertion hole 23b formed in the other end of the metal fitting body 23A is a long hole extending in the metal fitting longitudinal direction of the holding metal fitting 23, and corresponds to the insertion opening 23aa, the holding portion 23ab, and the communication portion 23ac of the notch 23a. The first hole 23ba, the second hole 23bb, and the communication hole 23bc are provided in a positional relationship.

  The holding portion 23ab of the notch 23a has an extension hole portion 23ad extending on the side opposite to the side on which the insertion opening portion 23aa opens, and the second hole portion 23bb of the insertion hole 23b is formed on the extension hole portion 23ad. Corresponding hole portions 23bd are provided.

  Also in this case, when fixing to the mast M, the wing nut 14 is loosened to support the both rod portions 12A and 12B in a horizontal state. First, as shown in FIG. The bolt member 12 is engaged with the mast M so that the mast M is positioned between the rod portion 12A and the screw rod portion 12B. Then, as shown in FIG. 17 (b), the holding metal fitting 23 is rotated about the screw rod portion 12B, and the insertion opening 23aa of the notch 23a is to be fixed to the locking rod portion 12A. Is engaged with the locking recess 12Aa corresponding to the diameter. Thereafter, the presser fitting 23 is moved in the Y direction (metal longitudinal direction). At this time, as shown in FIG. 16A, the positions of the center lines of the locking rod portion 12A, the mast M, and the screw rod portion 12B move from the positions Y11, Y21, Y31 to the positions Y12, Y22, Y32, respectively. . Then, as shown in FIG. 17 (c), the screw rod portion 12B is partly located in the second hole portion 23bb and partly in the hole portion 23bd, and the locking rod portion 12A is partly in the holding portion 23ab. Are slightly moved in the Z direction so as to be positioned in the extension hole portion 23ad, and the wing nut 14 is tightened and fixed.

  When the screw rod portion 12B is positioned in the second hole portion 23bb (hole portion 23bd) and the locking rod portion 12A is positioned in the holding portion 23ab (extension hole portion 23ad), the locking rod portion 12A is also a screw rod portion. 12B also restricts the movement of the holding metal fitting 23 in the longitudinal direction of the metal fitting and the direction orthogonal thereto, so that the notch 23a is not detached from the locking bar portion 12A, and the wing nut 14 can be easily tightened. Can do.

  In addition to the above embodiment, the present invention can be implemented with the following modifications.
