  The present invention relates to a clamp device that can be attached to a plate member by being inserted into one attachment hole provided in the plate member, and can suppress the protruding height of the plate member from the front and back sides.

  Patent Document 1 discloses a cable tie. The cable tie includes a columnar portion, an arrowhead-shaped snap piece, a leg piece disposed to face the snap piece, and a release piece. The snap piece is provided at the tip of the columnar part. The snap piece is elastically deformable in the radial direction. The release piece is connected to one end of the snap piece whose diameter is increased. The release piece can be shrunk by manual operation. When inserted into a hole provided in the substrate, the snap piece is elastically deformed in the radial direction. The elastically deformed snap piece sandwiches the substrate together with the leg piece. The columnar part includes a stopper part. The stopper portion prevents the columnar portion from being inclined more than a predetermined angle in the hole.

  According to the invention disclosed in Patent Document 1, mounting and dismounting of mounting components with respect to the substrate can be easily performed. In addition, according to the invention disclosed in Patent Document 1, it is possible to prevent the mounting component from naturally separating from the substrate. However, the invention disclosed in Patent Document 1 has the following problems. The problem is that when the cable tie is inserted into the hole provided in the substrate, the tip end portion of the snap piece protrudes from the hole of the substrate.

  The invention disclosed in Patent Document 2 and the invention disclosed in Patent Document 3 can solve the above-described problems. Patent Document 2 discloses a fixing member. The fixing member includes a main body, a column projecting from the main body, a plate-like body provided at the tip of the column, a projecting piece projecting from the main body, and a projection provided at the tip of the projecting piece. . At least a part of the plate-like body protrudes to the side of the column. The protruding piece is elastically deformable. When using the fixing member disclosed in Patent Document 2, first, a mounting hole and a positioning hole are made in the plate material. Next, the plate-like body and the support are inserted into the mounting holes from the front side of the plate material. Then, the protrusion is pressed against the front side of the plate material, and the protruding piece is elastically deformed. In this state, when the fixing member is slid in a direction parallel to the surface of the plate member, the plate member is displaced to a position where it overlaps the plate member. At the same time, since the elastically deformed protruding piece tries to return to its original shape, the protrusion fits into the positioning hole. For this reason, the fixing member is fixed to the plate material. According to the invention disclosed in Patent Document 2, it can be removed by an operation on the front side of the plate material, and the protruding amount on the back side of the plate material can be suppressed.

When someone inserts the sandwiching portion and the connecting portion into the mounting hole provided in the plate material, the edge portion of the mounting hole in the plate material is sandwiched between the sandwiching portion and the main body. The protrusion is provided on the holding portion. When the plate member is sandwiched between the main body and the sandwiching portion, the protruding portion is caught by the edge of the positioning hole of the plate member. Thereby, it is prevented that the edge part of an attachment hole is extracted from between a main body and a clamping part among board | plate materials. A part of the main body can be elastically deformed. For this reason, when the main body is pressed toward the mounting surface, the sandwiching portion, the connecting portion, and the protruding portion are displaced relative to the plate material. As a result, the protruding portion is not caught in the positioning hole of the plate material. According to the invention disclosed in Patent Document 3, it can be removed by an operation on the front side of the plate material, and the protruding amount on the back side of the plate material can be suppressed.

  However, the invention disclosed in Patent Document 2 and the invention disclosed in Patent Document 3 have a problem that a positioning hole must be provided in the plate material in addition to the mounting hole.

The fixing member is provided on the main body side in order to fix the main body and the plate material. This fixing member has a retaining portion projecting outward at the tip. When the retaining portion is displaced inward, the retaining portion can be inserted into and removed from the mounting hole formed in the plate material. On the other hand, when the retaining portion is inserted into the mounting hole and is displaced outward, the retaining portion is caught on the back side of the plate material and cannot be pulled out from the mounting hole. This fixing member also has a front side contact portion. The front side contact portion is provided outside the retaining portion. The front-side contact portion is pressed against the front side of the plate material when the retaining portion is inserted into the mounting hole. Thereby, it will be in the state which pinches a board | plate material between a front side contact part and a securing part. The fixing member also has an insertion portion. The insertion part is provided in the main body. The insertion portion is inserted between the retaining portions. The insertion portion displaces the retaining portion to the outside along with such insertion so that the insertion portion cannot be displaced inward. The fixing member also has an engaging portion and an engaged portion. One of these is provided on the main body side and the other is provided on the retaining portion side. The engaging portion and the engaged portion engage with each other when the insertion portion is inserted between the insides of the retaining portions. Thereby, the insertion part cannot be displaced from the inside of the retaining part. On the other hand, the engagement between the engaging portion and the engaged portion can be released by applying an external force. The fixing member also has a connecting portion. The connecting portion is connected to a retaining portion at one end and the main body or another retaining portion connected to the main body at the other end. The connecting portion is deformed so as not to prevent displacement of the retaining portion to the inside or outside and insertion of the insertion portion between the retaining portions.

  Even if the column portion 40 and one end of the retaining portion 44 penetrate the attachment hole 210, the contact portion 62 does not penetrate the attachment hole 210. The contact portion 62 receives a reaction force from the edge of the mounting hole 210 when the support column portion 40 and one end of the retaining portion 44 pass through the mounting hole 210. Since the reaction force is received, the contact portion 62 bends. When the contact portion 62 bends, the entire retaining portion 44 receives a moment due to the reaction force received from the edge of the mounting hole 210. The retaining portion 44 that has received the moment rotates around any position of the branch portion 42. As one of the branches 42 turns around the center of the rotation diagram, one end of the retaining portion 44 moves away from the support column 40. As a result, the retaining pawl 50 is caught on the edge of the mounting hole 210. FIG. 7 is a cross-sectional view of the plate member 200 when one end of the retaining portion 44 is being separated from the support portion 40 due to the contact portion 62 receiving a reaction force.

  As the retaining portion 44 rotates, the connection claw 70 enters the holding portion 90. When entering the holding portion 90, the connection claw 70 is caught by the holding claw 100. Since the connection claw 70 is caught by the holding claw 100, a state where one end of the retaining portion 44 is separated from the support column portion 40 is maintained. Since this state is maintained, the retaining pawl 50 cannot be removed while being caught on the edge of the mounting hole 210. Thereby, an electric wire and the board | plate material 200 are connected. FIG. 8 is a cross-sectional view of the plate member 200 when the connection claw 70 is hooked on the holding claw 100.

[Effect of the clamping device according to this embodiment]
