In the above conventional cable support bracket, it cannot be attached to the steel pipe material originally, and is attached to the steel pipe material by the clip force of the main body, so that it is easily removed when receiving an external force opposite to the flange insertion direction. Further, it is difficult to operate the insertion portion without using a jig such as a screwdriver to remove the gripping body from the main body. In addition, the structure is relatively complicated and is not easy to manufacture, which hinders cost reduction.
Then, this invention makes it a subject to provide the cable support metal fitting for solar cell modules which can be easily attached to the steel pipe material of a mount, and can be manufactured easily and inexpensively without coming off easily.

In order to solve the above-described problems, in the cable support fitting 1 for a solar cell module of the present invention, the cable C connected to the solar cell module is collectively supported by the steel pipe P assembled on the gantry supporting the solar cell module. Therefore, a U-shaped bolt 2 provided with leg portions 5 that are curved along the outer periphery of the steel pipe P and whose both end portions extend in parallel in the same direction, and screw portions 5a formed on these leg portions 5. And a stopper 3 that engages with each of the screw portions 5a and closes an open portion between the leg portions 5 and 5 of the U-bolt 2. The stopper plate 3 has an insertion hole 9 through which the leg portion 5 of the U-bolt 2 can be obliquely penetrated in the front-rear direction perpendicular to the interval direction, and toward the distal end side of the leg portion 5 that has penetrated the insertion hole 9. The plate spring portion 10 is inclined and presses the screw portion 5a to support the leg portion 5 in the insertion hole 9 obliquely in the front-rear direction. While allowing the leg portion to be inserted into the insertion hole 9 against the pressure of the leaf spring portion 10, the pressure of the leaf spring portion 10 whose tip has entered the thread valley of the screw portion 5 inserted into the insertion hole 9. And the spring 3 is rotated in the direction orthogonal to the leaf spring portion 10 to incline the leaf spring portion 10 in the direction of approaching the side surface of the leg portion 5 to weaken the spring force. The insertion hole 9 is substantially enlarged with respect to the leg part 5, and extraction is permitted.
The stopper 3 includes an engaging portion 6 having an insertion hole 9, an operating portion 6 that extends horizontally to one side in the front-rear direction of the engaging portion 6, and tilts the stopper by pushing down, and extends to the other. The return portion 7 is folded and has a leaf spring 9 at the tip.

  According to this invention, the steel pipe material and the cable are arranged inside the U-bolt, and the cable can be easily supported by the steel pipe material of the gantry by simply inserting the screw portions into the insertion holes of the clasps, In addition, since the leaf spring part securely prevents the screw part from coming off, it does not come off easily. Further, by tilting the stopper plate in a direction perpendicular to the leaf spring, it is removed from the U-bolt and easily removed from the steel pipe. be able to. In addition, because of the simple structure consisting of a general-purpose U-bolt that extends substantially along the outer circumference of the steel pipe and a stopper plate provided with an insertion hole for the leaf spring portion and the screw portion, manufacturing is easy and cost reduction can be realized. .

FIG. 2 is a side view of the cable support fitting of FIG. FIG. 2 is a longitudinal sectional view of the cable support fitting of FIG. FIG. 2 is an enlarged cross-sectional view of an engaging portion of the cable support fitting of FIG.

An embodiment of a cable support fitting according to the present invention will be described with reference to the drawings.
In FIG. 1 thru | or FIG. 4, the cable support metal fitting 1 supports the cable C connected to a solar cell module on the steel pipe material P assembled in the mount frame which installs a solar cell module. This cable support fitting 1 has a U-shaped bolt 2 whose center portion is curved and both ends extend in the same direction, and both ends of the U-bolt 2 are closed so as to close the opening between both ends. And a stopper 3 through which the screw portion 5 is inserted.

  The U-shaped bolt 2 includes an arcuate curved portion 4 along the outer periphery of the steel pipe P, parallel leg portions 5 continuous from both ends of the curved portion 4, and screw portions 5 a provided at end portions of the leg portions 5. Is provided.

  The clasp 3 is made of a rectangular steel plate, and is engaged by a plurality of longitudinal folds through an engagement portion 6 that penetrates the leg portion 5 of the U-bolt 2 and the front-rear direction of the engagement portion 6 (the axial direction of the steel pipe P to be mounted). ) It includes a return portion 7 that is continuous to one side, and an operation portion 8 that has a square cross section that is continuous to the other side of the engaging portion 6 in the front-rear direction. The engaging portion 6 is provided with an insertion hole 9 having a diameter sufficiently larger than that of the leg portion 5 so as to penetrate the leg portion 5 of the U-shaped bolt 2 so as to be swingable in the front-rear direction. One end of the return portion 7 is continuous with the engaging portion 6 and bent into a U-shaped cross section. The other end of the return portion 7 is continuous with a leaf spring portion 10 that extends obliquely downward in a direction intersecting with the engaging portion 6. The leaf spring portion 10 is inclined so as to approach the distal end side of the leg portion 5 as it approaches the leg portion 5 of the U-bolt 2 that has passed through the insertion hole 9, and press-contacts the screw portion 5 a of the leg portion 5. The leaf spring portion 10 urges the leg portion 5 to the side opposite to the leaf spring portion 10 in a state where the leg portion 5 of the U-shaped bolt 2 passes through the insertion hole 9, and thus the leg of the U-shaped bolt 2 in the vertical direction. The engaging portion 6 is relatively inclined with respect to the portion 5, and the leg portion 5 presses against the opening edges before and after the insertion hole 9, including the leaf spring portion 10, and holds the leg portion 5 at three points. When the operating portion 8 is pushed down while the leg portion 5 is held by the engaging portion 6, the engaging portion 6 rotates in a direction orthogonal to the leg portion 5, so that the insertion hole 9 is substantially formed with respect to the leg portion 5. The spring force is weakened by reducing the inclination angle of the leaf spring portion 10 with respect to the leg portion 5.

  The cable support fitting 1 is formed by hanging a U-shaped bolt 2 around a steel pipe P, disposing a cable C in the U-shaped bolt 2, and closing an open portion of the U-shaped bolt 2 with a stopper 3. Mounted on P to support cable C. When the leg portion 5 of the U-shaped bolt 2 is inserted into the stopper plate 3, the leaf spring portion 10 is pressed against the side surface of the leg portion 5 in the middle, but when the stopper plate 3 is tilted in the front-rear direction so as to lower the operation portion 8, Since the insertion hole 9 is substantially enlarged and the leaf spring portion 10 is inclined in the approaching direction with respect to the leg portion, the leg portion 5 can be entered without difficulty against the spring force. As shown in FIG. 5, the attached cable support fitting 1 is configured such that when the leaf spring portion 10 is pressed against the screw portion 5 a, the screw portion 5 a is held at three points on the opening edge before and after the leaf spring portion 10 and the insertion hole 9. The two points of the opening edge of the upper part of the leaf | plate spring part 10 and the insertion hole 9 bite into the screw thread of the screw part 5a with respect to extraction of the leg part 5, and the screw part 5a is prevented from falling out. On the other hand, when the stopper plate 3 is tilted in the front-rear direction so as to lower the operation portion 8 in the holding state, the insertion hole 9 is substantially enlarged, and the leaf spring portion 10 is inclined in the approaching direction with respect to the leg portion 5. The force is weakened and the legs 5 can be removed without difficulty.
