In the case where the conventional clip nut is used at a site where two plates are tightened with bolts and nuts and electrical conduction between the two is to be secured, the plate on which the clip nut is mounted is covered with an insulating coating film And electrical continuity between the two plates cannot be ensured.
Accordingly, an object of the invention according to this application is to provide a clip nut that can easily ensure electrical continuity between a plate member on which the plate is mounted and another plate member fastened to the plate member.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
The clip nut 1 of the invention according to this application for solving the above-described problems includes a clip body 2 that sandwiches a plate member 22 and a nut 3 that is held by the clip body 2. The clip body 2 is formed by bending a metal plate into a substantially U-shaped cross section, and has bolt insertion holes 4a and 5a corresponding to the bolt insertion holes 22a of the plate member 22, respectively, and the first piece portions 4 and The second piece 5 includes a bent portion 6 that joins one end sides of the two pieces 4 and 5, and a nut holding portion 7 provided on the outer surface of the first piece 4. The first piece 4 is disposed on the front surface side of the plate material 22, the second piece portion 5 is disposed on the back surface side of the plate material 22, and the plate material 22 is sandwiched between the two pieces 4, 5. The nut 3 is arranged on the outer surface of the first piece 4 of the clip body 2 so that the screw hole 3 a is matched with the bolt insertion hole 4 a and is held by the nut holding part 7. The second piece portion 5 of the clip body includes a holding portion 5b having one end side extending substantially parallel to the first piece portion 4 following the bent portion 6, and a first piece following the other end side of the holding portion 5b. A press-contacting piece portion 5 c that extends obliquely forward with respect to the portion 4, is bent when tightened by the bolt 21, and is press-contacted to the back surface side of the plate member 22. A plurality of pressure contact pieces 5c of the clip body 2 are pressed against the inner surface of the pressing member 5c so as to pass through a coating film or the like on the rear surface side of the plate member 22 and be pierced into the plate member 22 to be electrically connected. The conductive claws 8 are projected.

  According to the clip nut of the invention according to this application, it is possible to provide a clip nut that can easily ensure electrical continuity between a plate member to which the clip nut is mounted and another plate member fastened thereto.

It is a front view of the clip nut concerning the embodiment of the present invention. FIG. 2 is a side view of the clip nut of FIG. FIG. 2 is a plan view of the clip nut of FIG. FIG. 4 is a sectional view taken along line IV-IV in FIG. FIG. 2 is a cross-sectional view showing a usage state of the clip nut of FIG.

Embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 5, the clip nut 1 is mounted on one edge of two plate members 22 and 23 that are coupled to each other by a bolt 21, and is screwed to the bolt 21. In the illustrated embodiment, the plate member 22 is an inner flange of the frame of the solar cell module 24, and the plate member 23 is a part of a support member for supporting the solar cell module 24 on the structure. , 23 are electrically connected to provide grounding.

  The clip nut 1 includes a clip body 2 that sandwiches a portion corresponding to the bolt insertion hole 22 a of the plate member 22, and a nut 3 that is held by the clip body 2.

  The clip body 2 is formed by bending a metal plate into a substantially U-shaped cross section, and has bolt insertion holes 4a and 5a corresponding to the bolt insertion holes 22a of the plate member 22, respectively, and the first piece portions 4 and The second piece 5 includes a bent portion 6 that joins one end sides of both pieces 4 and 5, and a nut holding portion 6 provided on the outer surface of the first piece 4.

  The first piece 4 is disposed on the front surface side of the plate material 22, the second piece portion 5 is disposed on the back surface side of the plate material 22, and the plate material 22 is sandwiched between the two pieces 4, 5. At the periphery of the bolt insertion hole 4a, there is formed an engaging protrusion 4b that protrudes downward so that it can be easily positioned by engaging with the inner periphery of the bolt insertion hole 22a when mounted on the plate member 22. The

  The nut 3 is disposed on the outer surface of the first piece 4 so that the screw hole 3 a matches the bolt insertion hole 4 a and is held by the nut holding part 7. The nut holding part 7 is erected along the other side surface of the three contact pieces 7a rising from the peripheral edge of the first piece part 4 along the side surface of the nut 3, and refracted inward at the upper part. And a pair of pressing pieces 7b along the upper surface of the nut 3.

  The second piece portion 5 of the clip body 2 has a holding portion 5a having one end side extending substantially parallel to the first piece portion 4 following the bent portion 6, and a first portion following the other end side of the holding portion 5a. A press-contacting piece portion 5 b that extends obliquely forward with respect to the piece portion 4, is bent when tightened by the bolt 21, and is press-contacted to the back surface side of the plate material 22 is provided. On the inner side surface of the pressure contact piece portion, a plurality of conductive claws 8 are provided so as to pierce the back surface side of the plate member 22 and be in pressure contact so as to be electrically conductive when tightened by the bolt 21. When there is a coating film or the like on the back surface side of the plate material 22, the conduction claw 8 penetrates the plate material 22 and pierces the plate material 22.

  When joining the plate members 22 and 23, the clip nut 1 is first attached to a portion corresponding to the bolt insertion hole 22 a at the edge of the plate member 22. When the plate member 22 is inserted between the first piece portion 4 of the clip body 2 and the sandwiching piece portion 5b of the second piece portion 5 and appropriately moved, the engagement protrusion 4b engages with the bolt insertion hole 22a. The bolt insertion hole 4 a can be easily matched with the bolt insertion hole 22 a of the plate member 22.

  For example, as shown in FIG. 5, when the plate member 22 is an inner flange of the frame of the solar cell module 24, if the solar cell module 24 is disposed on the plate member 23 that is a support member, the plate member 22 that is a flange portion. Comes to a position that is not visible to the operator. However, since the nut 3 is mounted in advance so as to match the bolt insertion hole 22a of the plate member 22 that is the flange portion, the tightening operation of the bolt 21 is easy. When the bolt 21 is tightened, the pressure contact piece 5c bends and the conduction claw 8 pierces the back surface of the plate material 22, so that electrical conduction between the plate material 22 and the plate material 23 can be easily ensured. There is no need for additional work such as connecting a separate ground wire.
