Description

The present invention relates to a fixed unit .

2. Description of the Related Art Conventionally, there is known a fixture that attaches and detaches to and from a mounting hole formed in a substrate by using an elastic force in order to fix a wiring extending from an electronic component to a predetermined substrate. Since such fixtures are easily deformed, there is a risk that they may easily come off from the base when a large force is applied from the outside.

Therefore, in order to prevent such falling off, a configuration as disclosed in Patent Document 1 has been proposed. The fixture disclosed in Patent Document 1 includes a clamp portion that holds wiring, and a fixing portion that is integrated with the clamp portion and fits into a mounting hole of a board. Further, the fixed portion includes a cylindrical post, an engaging piece provided at the tip of the post and extending in one direction, and a pair of blade pieces extending outward from the base end of the post. . By inserting the engaging pieces into the mounting holes and rotating them along the surface of the substrate by 90°, the pair of blades are brought into contact with the surface of the substrate and clamp the substrate together with the engaging pieces.

JP 2003-329024 A

However, since the fixture disclosed in Patent Document 1 is configured to be locked by rotating it by 90 degrees with respect to the substrate, the arrangement state (fixed angle) of the clamp section with respect to the substrate is constant. Therefore, the guide direction of the wiring held by the clamp portion is fixed, and there is a possibility that a problem may arise in routing the wiring. Moreover, although the fixture of Patent Document 1 can hold the wiring, it cannot adjust the extra length of the wiring, so strict control of the length of the wiring is required. Therefore, it was difficult to adjust the length of the wiring even if there was a slight change in the design of the fixture or the like.

In the fixture of the present invention, the positioning locking group may be a collection of locking portions provided at predetermined intervals, and the locking portions may be arranged along the circumferential direction on the inner peripheral surface of the insertion hole. .

According to this configuration, it is possible to adjust the rotational position of the fixture with respect to the mounting plate portion with a simple configuration in which the locking portions are arranged at predetermined intervals along the circumferential direction on the inner peripheral surface of the insertion hole. .

In a fixture according to a second aspect of the present invention, the fixing portion includes a shaft-shaped base portion, a contact portion extending radially from one end side of the base portion and contacting one plate surface of the mounting plate portion, and an engaging piece extending radially from the other end side of the base portion and sandwiching the mounting plate portion together with the contact portion. Then, by inserting the base into the insertion hole so that the engaging piece passes through the cutout hole, and rotating the fixing member with respect to the mounting plate portion around the base, the mounting is performed by the contact portion and the engaging piece. The fixture can be assembled to the mounting plate portion by clamping the plate portion. On the other hand, the fixture can be removed from the mounting plate portion by rotating the fixture so that the engaging piece passes through the cutout hole and then removing the base from the insertion hole. Therefore, it is possible to easily attach/detach the fixture to/from the base only by rotating the fixture.
Moreover, the fixed portion has a positioning group including a plurality of positioning portions that are arranged along the circumferential direction of the base portion and can be positioned with respect to the locking portion of the mounting plate portion. Therefore, by rotating the fixture with respect to the mounting plate portion, the positioning portion to be locked by the locking portion is sequentially changed, and the rotational position of the fixture is adjusted in multiple stages. By adjusting the rotational position of the fixture with respect to the mounting plate portion in this manner, the wiring direction of the wire held by the holding portion can be guided in a desired direction. Thereby, the fixture can arbitrarily select the guiding direction of the wire rod. In addition, by winding the wire around the holding portion as the fixture rotates, the extra length of the wire can be wound. Therefore, the fixture can adjust the extra length of the wire rod.
Therefore, the fixture can be easily attached to and detached from the base body, can arbitrarily select the direction in which the wire is guided, and can adjust the excess length of the wire.

In the fixture of the present invention, the positioning group may be a set of positioning portions provided at predetermined intervals, and the positioning portions may be arranged along the circumferential direction of the base.

According to this configuration, it is possible to adjust the rotational position of the fixture with respect to the mounting plate portion with a simple configuration in which the positioning portions are arranged at predetermined intervals along the circumferential direction of the base portion.

In the fixture of the present invention, the holding part has a pair of holding pieces extending from the fixing part so as to face each other at a predetermined interval, and the wire rod is arranged between the pair of holding pieces to may be retained.

According to this configuration, the wire rod can be fixedly supported to the mounting plate portion simply by arranging the wire rod between the pair of holding pieces with respect to the fixture assembled to the mounting plate portion.

In the fixture of the present invention, engaging means for connecting the respective holding pieces is provided at the distal end of the pair of holding pieces, and at least one of the pair of holding pieces has the engaging means. It may have flexibility to be elastically deformable until the pair of holding pieces are connected to each other.

According to this configuration, after the wire is arranged between the pair of holding pieces, the wire can be held by the pair of holding pieces so that the wire cannot be detached by connecting the two holding pieces to each other by the engaging means. In particular, by elastically deforming one of the holding pieces in the direction of the other holding piece, both holding pieces are connected by the engaging means, so that the wire rod can be easily held by the holding portion.

In the fixture of the present invention, each of the pair of holding pieces may have claw pieces extending in opposite directions. A slit portion through which the wire passes may be configured by the opposed tip portions of the pair of claw pieces. In the slit portion, the opposing slit surfaces may be inclined in a plane orthogonal to the axial direction of the base portion with respect to the facing direction of the holding piece.

According to this configuration, the slit portion can widen the width of the slit surface compared to a non-inclined configuration in which the slit surface is orthogonal to the facing direction of the holding pieces. Therefore, even if the wire passed through the slit portion and placed between the pair of holding pieces is to be separated from between the holding pieces through the slit portion, the wire rod is likely to be caught by the claw pieces and is difficult to separate from between the holding pieces. Become.

The fixture of the present invention may have a suppressing portion that extends outside the holding portion and suppresses detachment of the wire wound around the holding portion.

According to this configuration, when the wire wound around the holding portion tries to move along the holding portion, it can be brought into contact with the suppressing portion extending to the outside of the holding portion to suppress separation. .

In the fixture of the present invention, the base protrudes from the mounting plate portion so as to be positioned on the rotational locus of the fixing portion in the vicinity of the mounting hole in a state in which the mounting plate portion is sandwiched between the abutting portion and the engaging piece. You may have the control part which carries out.

According to this configuration, the restricting portion is positioned on the rotation locus of the fixing portion, so that the fixing tool abuts against the restricting portion while the fixing tool is positioned at the predetermined rotational position, thereby restricting rotation. Therefore, the rotation range of the fixture can be limited to a desired range.

In the fixture of the present invention, the base body may have a scale indicating the degree of rotation of the holding part with respect to the mounting plate part in the vicinity of the mounting hole.

According to this configuration, the fixture can be easily rotated to a desired rotational position by using the scale indicating the degree of rotation of the holding portion with respect to the mounting plate portion as a reference.

A fixing structure of the present invention includes a fixing portion included in the fixture, and a mounting plate portion having a mounting hole to which the fixing portion is mounted.

According to this configuration, the fixing structure can achieve the same effects as the effects of the fixture.

The base 40 is, for example, a base that is housed in an electrical device, and has a plate-like mounting plate portion 41 . The wire L is, for example, wiring electrically connected to a circuit board. The fixture 10 is attached to the mounting plate portion 41 while supporting the wire L in order to route the wire L in an electric device or the like. A fixing unit 100 is configured by the fixture 10 and the base 40 .

As shown in FIG. 2, the fixture 10 holds a fixing portion 20 attached to a mounting hole 42 (see FIGS. 3 and 4) formed in the mounting plate portion 41, and a wire L (see FIG. 1). and a holding portion 30 for The fixing portion 20 is formed integrally with the holding portion 30 .

As shown in FIG. 2, the fixed portion 20 includes a shaft-shaped base portion 21 and a contact portion 22 (see FIG. 4) that contacts one plate surface (an upper surface 41A (see FIG. 1)) of the mounting plate portion 41. , a pair of engaging pieces 23 (see FIGS. 3 and 4) for holding the mounting plate portion 41 together with the contact portion 22, and a pair of positioning portions 24 (see FIG. 3) for positioning the base portion 21 with respect to the mounting plate portion 41. ) and The fixing structure of the present invention is configured by the fixing portion 20 and the mounting plate portion 41 .

The base 21 is formed in a hollow cylindrical shape. The abutting portion 22 is formed in a flange-like shape, projecting uniformly outward in the radial direction (radial direction) from one end portion side (upper end portion in FIG. 2) of the base portion 21 . Further, the contact portion 22 has a disk shape through which the center that communicates with the hollow portion of the base portion 21 is penetrated. As shown in FIG. 3, the pair of engaging pieces 23 protrude radially from the other end of the base 21 (lower end in FIG. 2) to symmetrical positions with respect to the center of the base 21. As shown in FIG. formed by Moreover, the engaging piece 23 has a rectangular parallelepiped shape with rounded corners on the side surface side and the lower end side. The positioning portion 24 protrudes radially from the side surface of the base portion 21 from a position adjacent to the engaging piece 23 (a position overlapping the engaging piece 23 in the axial direction). The positioning portion 24 is formed in a semi-cylindrical rib shape along the axial direction of the base portion 21 and extending between the contact portion 22 and the engaging piece 23 .

As shown in FIG. 2, the holding portion 30 has a pair of holding pieces 31 erected from the fixed portion 20 (abutting portion 22) so as to face each other with a predetermined interval. The wire rod L is held by arranging the wire rod L between 31 . Specifically, the holding piece 31 extends from one surface (upper surface in FIG. 2) of the contact portion 22 in a direction orthogonal to the one surface. The holding piece 31 is curved such that a surface (inner surface) facing the other holding piece 31 is recessed in an arc when viewed from the extending direction.

The holding piece 31 has a claw piece 32 extending toward the other holding piece 31 in a direction facing the other holding piece 31 (inward direction). The pair of claw pieces 32 are formed in a triangular plate shape so as to be symmetrical with respect to the axis of the base portion 21 (see FIG. 5(C)). A slit portion 33 through which the wire rod L passes is formed by both ends of the pair of claw pieces 32 facing each other. As shown in FIG. 5(D), the pair of opposing slit surfaces 34 constituting the slit portion 33 are arranged in a plane orthogonal to the axial direction of the base portion 21 (one surface of the contact portion 22) with respect to the facing direction. (in the plane parallel to the upper surface in FIG. 2). That is, it is inclined at a predetermined angle with respect to the facing direction of the holding piece 31 when viewed from the direction perpendicular to the axial direction of the base portion 21 (vertical direction in FIG. 4). As a result, the slit portion 33 can widen the width of the slit surface 34, that is, the width through which the wire L passes, as compared with the configuration in which the slit surface 34 is not inclined, and the wire L is less likely to come off while the wire L is held. Become.

As shown in FIG. 2, the holding piece 31 has a protruding portion 35 that protrudes to the outer peripheral position of the contact portion 22 in the opposite direction to the opposing direction of the holding piece 31 and extends over the entire extending direction of the holding piece 31. It is formed extending to The protruding portion 35 reinforces the holding piece 31 and serves as a portion around which the wire rod L is wound.

The mounting plate portion 41 has, as shown in FIG. 1, a positioning locking group 45 having a plurality of locking portions 46 with which the positioning portion 24 can lock. The locking portions 46 are arranged along the circumferential direction in the insertion hole 43 . Specifically, the positioning locking group 45 is a group of locking portions 46 continuously provided at predetermined intervals, and the locking portions 46 are formed on the inner peripheral surface of the insertion hole 43 (excluding the notch hole 44). portion) are arranged along the circumferential direction. The locking portion 46 is formed as a concave portion whose open end spreads outward. The locking portion 46 has an open end that is continuous with the open end of the adjacent locking portion 46, thereby forming a positioning locking group 45 in which the outwardly convex curved surface 43A is continuous. . With such a configuration, the positioning locking group 45 has a shape in which unevenness is continuously repeated along the circumferential direction on the inner peripheral surface of the insertion hole 43, and the curved surface 43A is continuous. The detachment is smooth, and the positioning state can be easily understood from the click feeling when the positioning part 24 and the locking part 46 are locked. In addition, molding is easy and sufficient strength can be ensured.

As shown in FIG. 1, the mounting plate portion 41 has a rotation degree of the fixture 10 (specifically, the holding portion 30) with respect to the mounting plate portion 41 in the vicinity of the mounting hole 42 (position slightly outside the edge). It has a scale 47 indicating . Scales 47 are formed on the upper surface 41A of the mounting plate portion 41 as numbers 1, 3, 5, 7, and 9. As shown in FIG. The scales 47 are provided corresponding to predetermined locking portions 46 , and numbers 1, 3, 5, 7, and 9 indicate predetermined rotational positions of the fixture 10 with respect to the mounting plate portion 41 . Although numbers 1, 3, 5, 7, and 9 are assigned in the embodiment, 10 locking portions 46 are provided on the half circumference of the mounting hole 42, and the fixture 10 is arranged in 10 stages. It is possible to adjust the rotation position.

Next, the process of fixing and supporting the wire L to the base 40 by the fixture 10 will be described.
First, as shown in FIGS. 5(C) and 5(D), the fixture 10 is inserted into the mounting hole 42 on the mounting plate portion 41 of the base 40 prepared as shown in FIGS. 5(A) and 5(B). do. Positioning is performed so that the pair of engaging pieces 23 are inserted into the pair of notch holes 44 , respectively, and the base portion 21 is inserted through the insertion holes 43 . Then, the pair of positioning portions 24 are also inserted into the pair of notch holes 44 , respectively, and the contact portions 22 contact the upper surface 41 A of the mounting plate portion 41 . The engagement piece 23 is positioned below the bottom surface 41B of the mounting plate portion 41 .

Subsequently, as shown in FIGS. 6A and 6B, the fixture 10 is rotated clockwise with respect to the mounting plate portion 41 around the base portion 21 (as shown in FIG. 6B, the mounting plate portion 41 is clockwise when viewed from the upper surface 41A side of ). Specifically, the fixture 10 is rotated so that one protrusion 35 is positioned adjacent to the number “3” on the scale 47 . At this time, one of the positioning portions 24 moves from the position inside the notch hole 44 shown in FIG. 3A to the position where it is locked by the locking portion 46 shown in FIG. Then, as shown in FIG. 4 , the mounting plate portion 41 is sandwiched between the contact portion 22 and the engaging piece 23 , and the fixture 10 is assembled to the mounting plate portion 41 . In this manner, the fixture 10 can be easily attached to the mounting plate portion 41 only by rotating the fixture 10 . Subsequently, the wire rod L is arranged between the pair of holding pieces 31 from the upper surface 41A side of the mounting plate portion 41 via the slit portion 33 . At this time, the wiring direction (longitudinal direction) of the wire L is parallel to the pair of slit surfaces 34 in the vertical direction. In this manner, the wire rod L can be held on the mounting plate portion 41 by the fixture 10 .

After that, as shown in FIGS. 6(C) and 6(D), the fixture 10 is further rotated clockwise. Specifically, the fixture 10 is rotated so that one protruding portion 35 moves from the number “3” on the scale 47 to a position adjacent to the number “7”. At this time, although illustration is omitted, one positioning portion 24 is moved from the locking portion 46 adjacent to the number "3" on the scale 47 to the locking portion 46 adjacent to the number "7". move to Since the pair of slit surfaces 34 are inclined with respect to the wiring direction (length direction) of the wire L when viewed from the top and bottom direction, and the pair of claw pieces 32 are positioned above the wire L, the wire L is Even if it tries to move upward, it does not come out through the slit part 33 by interfering with both claw pieces 32, and can be stably fixed and held between the pair of holding pieces 31. - 特許庁

Subsequently, as shown in FIGS. 7A and 7B, the fixture 10 is further rotated clockwise. Specifically, the fixture 10 is rotated so that the other projecting portion 35 is positioned adjacent to the number “1” on the scale 47 . At this time, the other positioning portion 24 moves so as to be locked to the locking portion 46 (not shown) adjacent to the number “1” on the scale 47 . One end (left side in FIG. 7(B)) of the wire L is wrapped around the protrusion 35 and the outer periphery of the holding piece 31 and fixed, and is in contact with the inner end of the holding piece 31. The other end (the right side in FIG. 7(B)) is guided in the clockwise direction around the part that abuts on the inner surface of the other holding piece 31 as a fulcrum. That is, in FIG. 7B, the wiring direction is guided so that the other end side of the wire L is parallel to the straight line passing through the number “5” of the scale 47 .

When the fixture 10 is further rotated clockwise from the states of FIGS. 7A and 7B, the locking portion 46 (not shown) to which the positioning portion 24 is locked changes stepwise. Therefore, by rotating the fixture 10 according to the numbers on the scale 47, the wiring direction of the other end of the wire rod L can be easily adjusted so as to face the desired guiding direction. In addition, as the fixture 10 rotates, the wire L is wound around the holding portion 30 while abutting on the projecting portions 35 from the outside. Length adjustment is possible.

Further, when the fixing member 10 is removed from the mounting plate portion 41, the pair of engaging pieces 23 overlap the pair of notch holes 44 in the vertical direction (states shown in FIGS. 5(C) and 5(D)). Then, the base portion 21 is removed from the insertion holes 43 so that the pair of engaging pieces 23 are inserted into the pair of notch holes 44, respectively. Thereby, the fixture 10 can be easily removed from the mounting plate portion 41 .

Therefore, by rotating the fixing member 10 with respect to the mounting plate portion 41, the locking portion 46 to which the positioning portion 24 is locked is sequentially changed, and the rotational position of the fixing member 10 is adjusted in multiple stages. By adjusting the rotational position of the fixture 10 with respect to the mounting plate portion 41 in this manner, the wiring direction of the wire rod L held by the holding portion 30 can be guided in a desired direction. Thereby, the fixture 10 can arbitrarily select the guiding direction of the wire rod L. As shown in FIG. Further, by winding the wire L around the holding portion 30 as the fixture 10 rotates, the extra length of the wire L can be wound. Therefore, the fixture 10 can adjust the extra length of the wire rod L. As shown in FIG.
