Description

[Technical Field]

[0001] The present invention relates to a mounting body that is attached by a rotational operation to a mounting space in which a pair of mounting grooves are arranged opposite each other, and a wiring pole device. [Background technology]

[0002] As shown in Patent Document 1, in order to enable a box to be attached to a wiring pole erected on the ground, the wiring pole is formed with a pair of left and right front plate portions in the vertical direction, with the tips of which are arranged opposite each other at a predetermined distance, and an opening is formed between the pair of front plate portions along the erection direction of the wiring pole.The clamping base V, which has a rectangular front shape, is attached to the wiring pole by first positioning the clamping base V, which is arranged vertically relative to the opening, at the back side through the opening and then rotating it approximately 90 degrees in a predetermined direction so that both longitudinal ends of the clamping base V are inserted and fitted into a pair of left and right fitting grooves 35 formed on the back side of the pair of front plate portions.

[0003] The elastic pieces 4 provided on the back side of both longitudinal ends of the clamping base V are brought into elastic contact with the abutment portions 36 that form the fitting grooves 35, and the elastic repulsive force of the elastic pieces 4 causes the clamping base V to elastically contact sharp abutment portions 37 formed on the inner surfaces of the front sides of the fitting grooves 35, thereby determining the position of the clamping base V along the formation direction of the fitting grooves 35. However, the elastic repulsive force of the elastic pieces 4 alone is insufficient to position the clamping base V relative to the pair of fitting grooves 35, and there are cases where the clamping base V falls inside the fitting grooves 35, and an improvement in this regard has been desired.

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-12872 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention aims to ensure the positioning of a pair of attachment grooves of an attachment body relative to an object to be attached in the direction of groove formation by increasing the sliding friction resistance of the attachment body against the edge portions formed on the inner surfaces of a pair of attachment grooves of the object to be attached. [Means for solving the problem]

[0006] The invention of claim 1 to solve the above problem is: An attachment body made of a metal plate that is attached by being pressed against an attachment object, The object to be attached has a pair of front plate portions whose tips extend in one direction with a predetermined distance between them, an opening formed between the tips of the pair of front plate portions, a pair of rear pressure contact portions arranged at a predetermined distance behind the pair of front plate portions, and a pair of side pressure contact portions arranged to connect the pair of front plate portions and the pair of rear pressure contact portions at a distance wider than the opening width of the opening, and a pair of attachment grooves arranged opposite each other; The attachment body has a width in a short direction that is narrower than the width of the opening, and a length in a long direction that allows it to be pressed against each of the side pressure-contact portions formed opposite each of the attachment grooves, After inserting the entire attachment body into the attachment space through the opening, the attachment body is rotated in a predetermined direction while being brought into sliding contact with each edge portion formed on the back side of the pair of front plate portions or at least one of the pair of rear pressure contact portions, so that a portion of both longitudinal end faces are pressed against each of the side pressure contact portions in a rotationally restricted state, and the attachment body is pulled forward by a drawing bolt, and a portion of the front face is pressed against the back side of the pair of front plate portions, thereby press-fitting the attachment body into the attachment space, In the press-fitted state, a through hole penetrating in the front-rear direction is formed by press punching in a portion of the attachment body that overlaps with the edge portion, and a burr is formed remaining on the tip side of the through hole in the punching direction, During the pressing and positioning of the attachment body, the burrs are crushed and sandwiched between the edge portion, thereby increasing the sliding friction resistance along the formation direction of the opening of the attachment body.

[0007] According to the invention of claim 1, when the attachment is placed in the attachment space of the attachment target with the longitudinal direction of the attachment target aligned with the opening direction of the attachment target, and the attachment is rotated in a predetermined direction in this state, both longitudinal ends of the attachment target are inserted into the attachment grooves of the attachment target and are pressed against the side pressure contact portions that make up the attachment grooves. Here, in this pressed-contact state, a through hole is formed by press-punching the attachment target in the front-to-rear direction at the part that overlaps with the edge portion, leaving a burr on the tip of the through hole in the punching direction. During the press-contact positioning of the attachment target, the burr is crushed and sandwiched between the attachment target and the edge portion, increasing the sliding friction resistance of the attachment target along the opening direction, and the attachment target does not move along the opening direction of the attachment target.

[0008] The invention of claim 2 is characterized in that, in the invention of claim 1, a front / back identification portion is formed along the longitudinal direction at one or both ends of the short side of the attachment body to indicate the side on which the burr is formed.

[0009] According to the invention of claim 2, the front / back identification portion formed on the attachment body makes it possible to accurately determine the side on which a tiny burr remains at the tip end of the through hole in the attachment body in the punching direction, and the surface of the attachment body on which the burr is formed can be reliably positioned opposite the edge portion formed in the attachment groove of the attached body.

[0010] The invention of claim 3 is the invention of claim 1 or 2, wherein the attachment body is in the shape of a parallelogram with a large slenderness ratio, and the pressure contact surfaces at both ends along the short side of the longitudinal end are formed into outwardly convex curved surfaces, Each side pressure-welding portion of the object to be attached is formed as an inclined surface that forms an acute angle with respect to the opening surface of the opening, In the pressure-welded arrangement state, one corner portion of the pressure-welding surface along the plate thickness direction is characterized by being pressed into the side pressure-welding portion.

[0011] According to the invention of claim 3, when both longitudinal ends of the attachment body are pressed against a pair of attachment grooves of the attached body, one corner along the plate thickness direction of the pressure-welding surface of the attachment body bites into and is pressed against the lateral pressure-welding portion that constitutes the attachment groove of the attached body. Therefore, this pressure-welding structure also makes it possible for the attachment body in the pressed-welding position to prevent the pressure-welding body from shifting along the direction in which the opening of the attached body is formed.

[0012] The invention of claim 4 is a wiring pole device comprising a wiring pole having the above-mentioned attachment space and the attachment body according to any one of claims 1 to 3.

[0013] According to the invention of claim 4, the attachment body described in any of claims 1 to 3 functions in cooperation with the bottom plate portion of the box attached to the wiring pole as a clamping base for clamping and fixing the front plate portion of the wiring pole, and the attachment position of the box relative to the wiring pole will not shift even with long-term use. [Effects of the Invention]

[0014] In the present invention, when the attachment body is pressed against the object to be attached, a through hole that penetrates in the front-to-rear direction is formed by press punching at the part of the attachment body that overlaps with the edge part of the attachment body, and burrs that remain on the tip side of the through hole in the punching direction are utilized, and during the pressure-contact positioning that is performed by rotating the attachment body, the burrs are crushed and sandwiched between the attachment body and the edge part, increasing the sliding friction resistance along the formation direction of the opening of the attachment body, and the attachment body does not shift or move along the formation direction of the opening of the attachment body.

[0016] The present invention will be described in more detail below with reference to the best embodiment. First, an example of the present invention applied to a distribution pole P will be described with reference to FIGS. 1 and 2. The distribution pole P is erected on a premises to pull in overhead electric wires for supplying power to a house and connect the overhead electric wires to underground electric wires via a box B. The distribution pole P comprises an irregular cylindrical outer cylinder A with a large, concave wiring groove 31 formed continuously in the axial direction along a portion of the circumference, and an irregular cylindrical inner cylinder D inserted into the outer cylinder A, the cross section of which is formed in a similar shape but slightly smaller than the outer cylinder A. Both the outer cylinder A and the inner cylinder D are made of metal. The inner cylinder D is inserted into the outer cylinder A by a predetermined length, and the outer cylinder A and the inner cylinder D are connected to each other at the overlapping portion via two connecting bolts 41 and nuts 42 arranged diametrically of the cylinders A and D. The nut plate N according to the present invention is inserted into the wiring groove 31 in the outer cylindrical body A through the opening 32, and is rotated by approximately 90° in a predetermined direction, so that both longitudinal ends of the nut plate N are inserted into the attachment grooves 35 described below, and both longitudinal ends are pressed against the side pressure contact portions 38 that constitute the attachment grooves 35, attaching the nut plate N to the inside of the opening 32, and attaching the box B to the opening 32 of the wiring groove 31 in the outer cylindrical body A via the nut plate N. The wiring groove 43 in the inner cylindrical body D is covered with a wiring cover 44, and a rubber cap 45 with an electric wire lead-in portion 45a is fitted to the upper end of the inner cylindrical body D, and a band 47 is attached directly below the cap 45 to the inner cylindrical body D to which a pulling wire 46 is connected for stably supporting the wiring pole P in an upright position.

[0017] Next, the outer cylindrical body A to which the nut plate N is attached will be described with reference to Figures 2 and 6. The outer cylindrical body A has a wiring groove 31, which has an isosceles trapezoidal cross section in part of its circumferential direction and is formed concavely inside the outer cylindrical body A, forming an irregular cylindrical shape. A pair of protrusions 33 are formed at both ends in the width direction of an opening 32 of the wiring groove 31 in the outer cylindrical body A, protruding radially outward from the outer cylindrical body A. The width W of the opening 32 is formed to be much larger (wider) than the width of the nut plate N, which has a parallelogram shape and will be described later. At the tip of the protrusion 33, a pair of band-like front plate portions 34 parallel to the rear flat plate portion 31a at the rear bottom of the wiring groove 31 extend along the axial direction of the outer cylindrical body A. A pair of left and right attachment grooves 35 into which both longitudinal ends of the nut plate N are inserted are formed on the back side of each front plate portion 34 of the protrusion 33, and the space where the attachment grooves 35 are arranged on both left and right ends forms an attachment space 36 in which the nut plate N is attached to the wiring pole P. On the back side of the front plate portions 34, sharp edges 37 with triangular cross sections are formed protruding into the attachment grooves 35, against which both front ends of the nut plate N are pressure-contacted. The bottom surfaces of the attachment grooves 35 form lateral pressure-contact portions 38 that extend approximately radially of the outer cylindrical body A.

[0018] Next, the nut plate N will be described in detail with reference to Figures 3 to 5. The nut plate N is formed by press-forming a metal plate, and has a parallelogram shape with a large slenderness ratio as a whole, and is composed of a pair of parallel long sides 1 and a pair of curved sides 2 that are deformed into a curved shape such that a pair of parallel imaginary short sides 2' are convex outward. A bisecting horizontal reference line HL perpendicular to the pair of imaginary short sides 2' and a bisecting vertical reference line VL perpendicular to the bisecting horizontal reference line HL are disposed at an intersection E thereof so as to bisect both a first line segment where the bisecting vertical reference line VL intersects with the pair of long sides 1 and a second line segment where the bisecting horizontal reference line HL intersects with the pair of curved sides 2, and an internal thread portion 3 is formed at the intersection E of the vertical and horizontal reference lines VL and HL. The intersection angle between the long side 1 and the imaginary short side 2' of the nut plate N (equal to the intersection angle between the long side 1 and the bisecting vertical reference line VL) is θ0 (75° in the illustrated example). The nut plate N is fixedly positioned in the attachment space 36 by being pressed against a pair of side pressure contact portions 38 formed opposite the outer cylindrical body A, utilizing the fact that both ends are on the curved side 2 and the length of the line segment L passing through the intersection E gradually decreases or increases from one end of the curved side 2 to the other.

[0019] The female thread portion 3 is formed by punching pilot holes during press molding, and then forming the female thread in the pilot hole in a later process. The central portion of the portion of the nut plate N facing the pair of long sides 1 is cut and raised in a rib shape toward the surface 4 during press molding, forming each front / back identifier 5. When the nut plate N is attached to the outer cylindrical body A, it is pulled toward the front side where the box B is placed by the draw fastening bolt J described below, and a large bending force acts along the direction of the long sides 1, and the front / back identifier 5 also functions to increase the bending strength of the nut plate N along the longitudinal direction. In addition, the pair of curved sides 2 of the nut plate N are punched out by a punching process (shearing process) using a press, and thus elongated holes 6 are formed parallel to the bisecting vertical reference line VL or the imaginary short side 2'. Therefore, the nut plate N, including the pair of front / back distinguishing portions 5 and the pair of elongated holes 6 formed therein, has a shape that is point-symmetrical with respect to the intersection point E, and therefore the intersection point E is also the center of point symmetry. In addition, in Figures 3 to 5, reference numeral (7) indicates the back surface of the nut plate N.

[0020] When the oblong hole 6 is punched into the nut plate N by punching using a press, a punch corresponding to the shape of the oblong hole 6 is moved relative to a die supporting the material, and the material is sheared between the die and the punch, so that a rounded "sag 8 (see Figure 9(a))" occurs on the inner peripheral surface of the punched oblong hole 6 on the side where the punch first hits, and a burr 9 that protrudes slightly from the plate surface of the nut plate N occurs on the inner peripheral surface on the opposite side of the oblong hole 6. In general press-punched products, the burrs protrude from the surface of the punched product, and therefore are generally removed because they can injure the worker when handling the product and hinder adhesion when the product is to be tightly attached to another member for assembly. In the present invention, contrary to the conventional general approach to burrs, the burrs that are inevitably generated when a hole is punched in a metal plate by shear forming are intentionally left, and by bringing the burrs into close contact with the contact surface of the mating member, the sliding friction force of the metal plate against the mating member is increased. Note that the burrs 9 in Figure 9 are shown schematically.

[0021] Therefore, to place the nut plate N in the attachment space 36 formed at the rear of the opening 32 of the outer cylinder A, as shown in Figure 6, by confirming that the front / back identification part 5 is located on the front side, the front surface 4 of the nut plate N is located on the front side, and with its longitudinal direction aligned vertically, the nut plate N is inserted and placed through the opening 32 into the attachment space 36 at the rear. In this state, when the nut plate N is rotated clockwise around the intersection E of the reference lines HL and VL, as shown in Figure 7, the rotation resistance increases suddenly just after the curved end faces 2a at both ends of the longitudinal direction of the nut plate N are pressed against the lateral pressure contact portions 38 that constitute the attachment groove 35 at the pressure contact points S, and just before the corners 2b of the curved end faces 2a of the nut plate N bite into the lateral pressure contact portions 38. Therefore, when the rotation is stopped at this position, the nut plate N is fixed and placed in an inclined position in the attachment space 36 of the wiring pole P. The pair of left and right side pressure contact portions 38 are aligned along the radial direction of the outer cylinder A and are formed at an incline so as to form a "V" shape when viewed in a plane, so that one corner 2b in the thickness direction of the curved end face 2a of the nut plate N is pressed against the side pressure contact portion 38 and maintained in this state. In this state, the angle of intersection between the long side 1 of the nut plate N and the vertical line is θ1 (θ1<θ0) (72° in the illustrated example), and the direction in which the long hole 6 of the nut plate N is formed (the direction of the bisecting vertical reference line VL) and the vertex line 37a of the edge portion 37 that forms the attachment groove 35 of the outer cylinder A are arranged in a non-parallel state just before becoming parallel, and at the intersection points K1, K2 between the vertex line 37a of the edge portion 37 and the periphery of the long hole 6 of the nut plate N, the surface 4 of the nut plate N abuts against the edge portion 37 with the burr 9 interposed (biting into) that protrudes beyond the periphery of the long hole 6 and is turned over by contact with the vertex 37a of the edge portion 37 when the nut plate N is rotated (see Figure 10).

[0022] Then, as shown in Figures 1 and 10, inside the box B arranged in front of the pair of left and right front plate portions 34 of the wiring pole P, the nut plate N is pulled toward the box B by the pull-in fastening bolt J inserted into the bottom plate portion 11, and the nut plate N and the bottom plate portion 11 of the box B are fastened together by the pull-in fastening bolt J, whereby the box B is installed at a predetermined height position of the wiring pole P.

[0023] As shown in Figure 10, the nut plate N and the bottom plate 11 of the box B are fastened together by a draw fastening bolt J with burrs 9 remaining between the edge portion 37 of the mounting space 36 of the wiring pole P and the nut plate N, which remain on the periphery of each elongated hole 6 on the surface 4 of the nut plate N and are turned over by contact with the edge portion 37 when the nut plate N rotates. Therefore, the burrs 9 interposed between the edge portion 37 and the nut plate N act as a large resistance to the downward sliding of the box B due to its own weight, so that the box B does not slide downward easily.

[0024] Furthermore, the vertex 37a of the edge portion 37 of the outer cylindrical body A and the nut plate N are in point contact at two points, the intersection points K1 and K2, with the burr 9 interposed between them, unlike the previous surface contact which is close to a narrow line contact due to the vertex 37a being a narrow surface or line.Therefore, when the box B is fastened to the outer cylindrical body A via the draw-in fastening bolt J, the tightening force acts concentratedly on the two points, the intersection points K1 and K2, and the force which integrates the box B with the outer cylindrical body A also increases, and downward sliding of the box B can be prevented for a reason other than the increase in the sliding friction force.

[0025] Furthermore, the outer cylinder A and nut plate N that constitute the wiring pole P are both made of metal, but for example, if the outer cylinder A is made of aluminum and the nut plate N is made of carbon steel and the material of the nut plate N is harder than the material of the outer cylinder A, the rotation resistance will increase suddenly after the corners 2b of the curved end faces 2a at both ends of the longitudinal direction of the nut plate N are pressed against the side pressure contact portions 38 that constitute the attachment groove 35. If the nut plate N is forced to rotate further in the same direction in this state, as shown in Figure 8, the corners 2b of the curved end faces 2a at both ends of the longitudinal direction of the nut plate N will bite into the side pressure contact portions 38 by a predetermined length, and the rotation will stop in this state. In the arrangement of the nut plate N in Figure 8, a pair of imaginary short sides 2' are arranged vertically, and the angle between the long side 1 and the vertical is θ0 (75° in the illustrated example). In this arrangement of the nut plate N, burrs 9 are interposed between the vertex 37a of the edge portion 37 and the periphery of the elongated hole 6 of the nut plate N at the intersections K3 and K4 between the vertex line 37a of the edge portion 37 and the periphery of the elongated hole 6 of the nut plate N, thereby increasing sliding friction resistance. Furthermore, in the arrangement of the nut plate N shown in Figure 8, the corners 2b of the curved end faces 2a at both ends of the longitudinal direction of the nut plate N are embedded into the lateral pressure contact portions 38 by a predetermined length, which also prevents the nut plate N from sliding. Note that in Figure 8, T indicates the length of the portion where the corners 2b of the curved end faces 2a of the nut plate N are embedded into the protrusion 33 of the outer cylindrical body A. Furthermore, even if the embedding of the corners 2b of the curved end faces 2a is insufficient, the increased sliding resistance caused by the burrs contributes to preventing the nut plate N from falling under its own weight along the mounting groove 35.

[0026] In addition, in the above embodiment, the long hole 6 is formed by press punching in the portion of the nut plate N that overlaps with the edge portion 37 of the outer cylinder A when attached. However, if multiple circular holes are formed instead of the long hole 6, the area where burrs can be pinched between the vertex 37a of the edge portion 37 will increase, further increasing the sliding friction resistance of the nut plate N against the edge portion 37.
