  Preferred embodiments of the present invention are shown below. The cable straightening member according to the present embodiment is a case for holding the cables in the casing together in an electric equipment storage box formed of a vertical frame, a horizontal frame, a depth frame and side plates, a ceiling plate, a bottom plate, and a door. It is a cable straightening member used by being attached to a body frame. FIG. 1 and FIG. 2 show a use state diagram in which two cable straightening members 1 are connected and then attached to the frame 2. As shown in FIGS. 1 and 2, a plurality of substantially U-shaped slide grooves 3 that are used as attachment portions of the cable wire-shaping member 1 are formed in each frame.

  As shown in FIGS. 3 to 7 and 12, the cable straightening member 1 has a substantially square shape. A rotation fixing portion 4 that is rotated and fixed after insertion along a substantially U-shaped slide groove 3 formed in the longitudinal direction of the frame 2 on one side (fixed side 7) of the rectangular shape, and a cable An anti-rotation portion 5 is formed that suppresses rotation of the rotation fixing portion 4 by abutting with the wall portion 28 of the frame 2 at the fixing position of the wire-shaping member 1 or by fitting with the concave groove 21 formed in the frame 2. In the adjacent side (fixed side 8), a fixed portion 6 used when connecting another cable straightening member 1 is formed. The wall portion 28 close to the slide groove 3 may be formed close to the slide groove 3 as shown in FIG. 12, or as another example, formed only by the slide groove 3 as shown in FIG. It may be in contact with the wall portion 28 of the frame 29. The frame 29 can be used by being provided on a side plate of an electric equipment storage box surrounded by a side plate, a ceiling plate, a door portion, a back plate and the like.

  Of the both ends of the fixed side 7, one end is adjacent to the fixed side 8, and the rotation preventing part 5 is formed at the other end. On the back side of the rotation prevention unit 5, the rotation fixing unit 4 is released from the state in which the rotation fixing unit 4 is in contact with or fitted with the slide groove 3, and has an operation unit 9 at the tip for enabling the rotation fixing unit 4 to rotate again.

The arm portion includes a long arm portion 11 connected to the fixed side, and a short arm portion 12 formed by bending the long arm portion 11, and the short arm portion 12 and the operation side 10 are formed. A gap 13 used as a wire insertion hole is formed in between.

  When the cable inserted from the electric wire insertion hole is thick, the substantially L-shaped arm portion is fixed to the fixed side 7 and the L-shaped arm portion so that the L-shaped arm portion can be bent and inserted. It is thinner and easier to bend than the two fixed sides 8. Only the short arm 12 may be formed thin and easily bent, but if it is formed thin and easily bent over the L shape, it can be bent with a smaller force. On the other hand, if the fixed side 7 is formed thin and easily bent, there is a risk of deformation and damage without being able to withstand the load of the cable. If the fixed side 8 is formed thin and easily bent, other cables Since there is a risk that the holding force when the straightening member 1 is connected to the fixed portion 6 of the fixed side 8 is weakened, the fixed side 7 and the fixed side 8 are formed thicker than the substantially L-shaped arm portion. To avoid these dangers.

(Rotation fixed part)
As shown in FIGS. 5 and 6, the rotation fixing portion 4 is formed from a shaft portion 18 protruding from the fixed side 7, and the length of the short side is a substantially U-shaped slide groove 3 formed in the frame 2. It has a substantially rectangular shape formed in accordance with the lateral width of the gap between the left and right sides 16 and is formed as a cut-off portion 15 with one pair of diagonals cut off into a corner 14 and the other diagonal cut into an arc.

  As shown in FIG. 8, after the rotation fixing part 4 is inserted into the slide groove 3 of the frame (FIG. 8-a), the cable fixing member 1 is rotated clockwise to rotate the rotation fixing part 4 ( 8B), the rotation fixing portion 4 and the fixed side 7 are fixed by sandwiching the left and right sides 16 of the slide groove 3 (FIG. 8-C). At the fixed position, the corner portion of the rotation fixing portion 4 is in contact with the wall portion in the groove portion, so that further rotation is suppressed.

  As shown in FIGS. 5 and 8-a, the short side of the rotation fixing portion 4 is formed so that the plate thickness increases toward the center. The gap 17 between the thickest portion and the fixed side 7 is formed to have the same width as or narrower than the thickness of the left and right sides 16 of the groove 3 of the frame 2. Therefore, when the rotation fixing portion 4 is inserted into the slide groove 3, the left and right sides 16 of the slide groove 3 are sandwiched while being guided by the thin portion of the plate thickness, and when the rotation angle is rotated 90 ° from the insertion angle, the plate thickness is the thickest. The part and the left and right sides 16 are in contact with each other, so that the left and right sides 16 can be firmly sandwiched and fixed.

  As shown in FIGS. 3 and 5, the rotation fixing portion 4 is formed on the fixed side 7 via the shaft portion 18. 9 and 10 are views showing a cross-sectional shape of the shaft portion 18 formed on the fixed side 7, and the shaft portion 18 has a substantially rectangular shape like the rotation fixed portion 4, and has a pair of diagonals. Is formed as a cut-off portion 20 in which the corner portion 19 is cut off and the other diagonal portion is cut off in an arc shape. As shown in FIG. 10, when inserted into the slide groove 3 of the frame 2, the shaft portion 18 is in contact with the ends of the left and right sides 16 of the slide groove 3. Since the corner portion 19 is formed on one side and the cut-off portion 20 is formed on the other side, the corner portion 19 abuts against the end portions of the left and right sides 16 even if it is rotated in the direction of the corner portion 19, but cannot be rotated any further. When it is rotated in the opposite direction, it is formed by the cut-off portion 20, so that it can be rotated. That is, the rotation can be performed only in one direction, and the rotation operation can be performed without mistaking the rotation direction.

(Anti-rotation part)
As shown in FIG. 5, the rotation prevention unit 5 is formed at the end of the fixed side 7 as an inclined side. When the rotation preventing portion 5 is configured as a flat block body instead of an inclined side, a large load is required to get over the block body when the rotation fixing portion 4 is removed from the fixed position and can be rotated again. On the other hand, by forming the rotation preventing portion 5 as an inclined side, the rotation fixing portion 4 can be easily detached from the fixed position while sliding on the outer periphery of the slide groove 3 with which the rotation preventing portion 5 is in contact or fitted. Can be rotated again.

  As shown in FIGS. 2 and 3, in a state where the rotation fixing portion 4 and the fixed side 7 are fixed with the left and right sides 16 of the slide groove 3 being sandwiched, the rotation prevention unit 5 is provided on either side of the slide groove 3. When the rotation fixing part 4 is fitted further into the concave part 21 formed on one side and further rotated or rotated to the opposite side, one side surface of the rotation prevention part 5 comes into contact with the concave groove 21. It has a structure that suppresses rotation. In the present embodiment, the shape of the portion in contact with the rotation preventing portion 5 is formed as the concave groove 21. However, the shape is not limited to the concave groove, and the rotation fixing portion 4 and the fixed side 7 are the left and right sides of the slide groove 3. In a state in which the side 16 is sandwiched and fixed, a portion that contacts the side of the rotation preventing portion 5 is formed on one side, such as forming a wall portion 28 close to the slide groove 3 as shown in FIGS. If it exists, the effect of the rotation prevention part 5 can be acquired. As described above, by adopting the configuration having the rotation prevention unit 5 that suppresses the rotation of the rotation fixing unit 4, the cable straightening member 1 is displaced from the fixing position due to the load of the cable or the contact of the operator at the fixing position. It can be fixed so that there is no problem, and the mounting strength of the cable straightening member 1 is also improved.

  As described above, on the back side of the rotation prevention unit 5, the operation unit 9 for releasing the state where the rotation fixing unit 4 is in contact with or fitting with the slide groove 3 and allowing the rotation fixing unit 4 to rotate again. Is formed as a deflectable side that can be bent, and the operator pulls the operating part 9 formed at the tip of the operating side 10 for the first time. 4 has a structure in which it can be rotated again out of the fixed position. Also, as shown in FIG. 3, by forming the gap 13 serving as an electric wire insertion part on the extension of the end face of the frame 2, the cable can be easily inserted along the end face of the frame 2. Become.

  When the locking only by the rotation preventing part 5 becomes unstable, as shown in FIGS. 4 and 5, a screwing hole 22 is formed adjacent to the rotation preventing part 5 so as to be screwed. As described above, since the substantially L-shaped arm portion opposed to the fixed side 7 is formed thin, a tool can be inserted from the approximately L-shaped arm portion and screwed into the screw hole 22. it can.

(Fixed part)
As shown in FIG. 11, the fixed portion 6 is formed with a recess 23 into which the long side of the rotation fixing portion 4 of another cable straightening member 1 can be inserted. A groove portion 24 into which 4 can be fitted is formed. In the depth direction of the groove portion 24, a hole portion 26 into which a circular protrusion 25 formed on the rotation fixing portion 4 of the fixed side 7 can be inserted is formed. The hole 26 serves as a positioning means, and when the protrusion 25 is inserted into the hole 26, the rotation fixing part 5 can be fitted into the groove 24, and the protrusion 25 is not inserted into the hole 26. In the state, it is impossible to rotate. Further, by inserting the projection 25 into the hole 26, the attachment strength at the time of connecting the cable straightening member 1 is improved.

  As shown in FIG. 6, the circular protrusion 25 and the shaft portion 18 are arranged so as to be offset from the center of the rotation fixing portion 4. When the protrusion 25 and the shaft portion 18 are formed at the center position of the rotation fixing portion 4, it is necessary to open the recessed portion 23 of the fixed portion 6 deeply, and when the opening of the recessed portion 23 becomes large, only the portion of the fixed portion 6 is weakened. It may become damaged. On the other hand, by biasing the center, the opening of the recess 23 can be reduced, and the strength can be maintained. Further, when the shaft portion 18 is formed at the center position of the rotation fixing portion 4, the shape of the shaft portion 18 of the rotation fixing portion 4 is large despite the fact that the corner portion 19 and the cut-off portion 20 are formed as described above. If the force is applied, it can be rotated, and if it is forcibly rotated, there is a risk of damaging the cable wire-shaping member 1. Can be avoided.

  In addition, a recessed portion 27 into which the rotation preventing portion 5 of another cable straightening member 1 can be inserted is formed in the left-right direction of the fixed portion 6. By forming a concave groove 27 corresponding to the concave groove 21 into which the rotation preventing portion 5 of the frame 2 can be inserted in the fixed side 8, it is possible to suppress the rotation even when another cable wire-shaping member 1 is connected. Is formed. In addition, the storage device in the electric device storage box is provided with the fixed portion 6 that can be fixed to the fixed side 7 by rotating the rotation fixing portion 4 of the other cable-shaping member 1 having the same shape. Even if the amount of cable routing increases, or when it is necessary to increase the number of cable wire-shaping members 1 due to circumstances such as the need to divide the cables, other cable adjustments can be made by simple installation work. The wire member 1 can be added.
