Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, since a conventional clamp can be assembled to electric wires having different diameters and hold the electric wires, dedicated products for each electric wire diameter are not required. However, in order to accommodate electric wires having different diameters, this conventional clamp requires a plurality of members and requires assembling these plurality of members. Therefore, there is room for improvement in the conventional clamp.

[0005] Therefore, the object of the present invention is to provide a clamp that can be attached to electric wires or bundles of electric wires of different diameters. [Means for solving the problem]

[0006] The present invention comprises a first clamping body, a second clamping body, a living hinge connecting one end of the first clamping body and the second clamping body, and a coupling structure that connects the other ends of the first clamping body and the second clamping body by fitting together a first coupling body provided on the other end of the first clamping body and a second coupling body provided on the other end of the second clamping body, wherein the living hinge has a maximum wire holding position for the first clamping body and the second clamping body when the object to be held is a wire or wire bundle of the maximum diameter, and a maximum wire holding position for the first clamping body and the second clamping body when the object to be held is a wire or wire bundle of the minimum diameter, and a position for the first clamping body and the second clamping body to house the wire or wire bundle in an internal space consisting of the first clamping body and the second clamping body The clamping body is formed such that the first and second clamping bodies can rotate between them at the minimum wire holding position of the two clamping bodies, the first clamping body is flexible enough to move in and out of the internal space, and has a flexible portion that, when at the minimum wire holding position, clamps the wire or wire bundle of the smallest diameter between itself and the second clamping body within the internal space, the coupling structure is characterized by coupling the other ends of the first and second clamping bodies at the maximum wire holding position by fitting the first and second coupling bodies at the first fitting position, and coupling the other ends of the first and second clamping bodies at the minimum wire holding position by fitting the first and second coupling bodies at the second fitting position.

[0009] An embodiment of the clamp according to the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention.

[0010] [Embodiment] One embodiment of the clamp according to the present invention will be described with reference to Figures 1 to 7.

[0011] Reference numeral 1 in Figures 1 to 5 indicates a clamp in this embodiment. This clamp 1 holds an electric wire We or a bundle of multiple electric wires Web, and by attaching it to a clamp fixing target (such as a vehicle body structure), it aims to restrict the path of the electric wire We or bundle of electric wires Web and prevent interference with surrounding parts.

[0012] The clamp 1 comprises a first clamping body 10, a second clamping body 20, and a living hinge 30 connecting one end of the first clamping body 10 and the second clamping body 20 (Figures 1 to 5). In this clamp 1, an electric wire We or an electric wire bundle Web is placed between the first clamping body 10 and the second clamping body 20 in the open state via the living hinge 30, and the first clamping body 10 and the second clamping body 20 are rotated to the closed state via the living hinge 30, thereby clamping the electric wire We or electric wire bundle Web between the first clamping body 10 and the second clamping body 20. In this clamp 1, an internal space 1a is formed, closed by the first clamping body 10 and the second clamping body 20 in the closed state, and the electric wire We or electric wire bundle Web is held in this internal space 1a, clamped between the first clamping body 10 and the second clamping body 20 (Figures 1 to 4).

[0013] The first clamping body 10 has a first arc-shaped portion 11 having an arc-shaped inner wall surface (hereinafter referred to as the "first arc-shaped surface") 11a, a first connecting portion 12 having a smooth inner wall surface (hereinafter referred to as the "first plane") 12a connected to one end of the first arc-shaped surface 11a in the circumferential direction, and a second connecting portion 13 having a smooth inner wall surface (hereinafter referred to as the "second plane") 13a connected to the other end of the first arc-shaped surface 11a in the circumferential direction (Figures 1 to 5). The first clamping body 10 shown here has a first arc-shaped surface 11a that is arc-shaped with a central angle of 90 degrees, a first plane 12a that extends tangentially from one end of the first arc-shaped surface 11a, and a second plane 13a that extends tangentially from the other end of the first arc-shaped surface 11a.

[0014] The second clamping body 20 has a second arc-shaped portion 21 having an arc-shaped inner wall surface (hereinafter referred to as the "second arc-shaped surface") 21a, a third connecting portion 22 having a smooth inner wall surface (hereinafter referred to as the "third plane") 22a connected to one end of the second arc-shaped surface 21a in the circumferential direction, and a fourth connecting portion 23 having a smooth inner wall surface (hereinafter referred to as the "fourth plane") 23a connected to the other end of the second arc-shaped surface 21a in the circumferential direction (Figures 1 to 5). The second clamping body 20 shown here has a second arc-shaped surface 21a with a central angle of 90 degrees, a third plane 22a extending tangentially from one end of the second arc-shaped surface 21a, and a fourth plane 23a extending tangentially from the other end of the second arc-shaped surface 21a.

[0015] In this clamp 1, when the first clamping body 10 and the second clamping body 20 are in the closed state, the first plane 12a of the first clamping body 10 and the fourth plane 23a of the second clamping body 20 are positioned parallel to each other, and the second plane 13a of the first clamping body 10 and the third plane 22a of the second clamping body 20 are positioned parallel to each other (Figures 2 and 4).

[0016] Furthermore, in this clamp 1, the end of the first connecting portion 12 opposite to the first arc-shaped portion 11 becomes one end of the first clamping body 10, and the end of the third connecting portion 22 opposite to the second arc-shaped portion 21 becomes one end of the second clamping body 20. For this reason, in this clamp 1, the ends of the first connecting portion 12 and the third connecting portion 22 are connected by a living hinge 30 (Figures 1 to 5).

[0017] This clamp 1 holds at least an electric wire We1 or a wire bundle Web1 with the maximum diameter and an electric wire We2 or a wire bundle Web2 with the minimum diameter (Figs. 1 to 4). This clamp 1 forms a living hinge 30 and a first clamping body 10 as follows to correspond to electric wires We or wire bundles Web of at least two types of diameters. However, the clamp 1 shown here also holds an electric wire We or a wire bundle Web having a diameter between its maximum diameter and minimum diameter. For example, here, as an electric wire We or a wire bundle Web having a diameter between its maximum diameter and minimum diameter, an electric wire We3 or a wire bundle Web3 or an electric wire We4 or a wire bundle Web4 is held (Figs. 6 and 7). Here, the diameter of the electric wire We4 or the wire bundle Web4 is smaller than the diameter of the electric wire We3 or the wire bundle Web3.

[0018] The living hinge 3 is formed such that the first clamping body 10 and the second clamping body 20 can be rotated relative to each other between a maximum wire holding position (Figs. 1 and 2) where the electric wire We1 or the wire bundle Web1 with the maximum diameter is clamped and held by the first clamping body 10 and the second clamping body 20 when the object to be held by the clamp 1 is the electric wire We1 or the wire bundle Web1 with the maximum diameter, and a minimum wire holding position (Figs. 3 and 4) where the electric wire We2 or the wire bundle Web2 with the minimum diameter is accommodated in an internal space 1a formed by the first clamping body 10 and the second clamping body 20 when the object to be held is the electric wire We2 or the wire bundle Web2 with the minimum diameter.

[0019] Here, in this clamp 1, when the first clamping body 10 and the second clamping body 20 are in the closed maximum wire holding position, the minimum distance between the inner wall surface of the first clamping body 10 and the inner wall surface of the second clamping body 20 is slightly smaller than the diameter of the electric wire We1 or the wire bundle Web1 with the maximum diameter. Also, in this clamp 1, when the first clamping body 10 and the second clamping body 20 are in the closed minimum wire holding position, the minimum distance between the inner wall surface of the first clamping body, 10 and the inner wall surface of the second clamping body 20 is slightly smaller than the diameter of the electric wire We2 or the wire bundle Web2 with the minimum diameter

[0020] Furthermore, the first clamping body 10 is flexible enough to move in and out of the internal space 1a, and has a flexible portion 14 that, when in the minimum wire holding position, clamps the wire We2 or wire bundle Web2 of the smallest diameter between itself and the second clamping body 20 within the internal space 1a (Figures 4 and 5).

[0021] Here, the first clamping body 10 has a through hole 15 that connects the inside of the internal space 1a to the outside (Figure 5). The flexible portion 14 is housed inside the through hole 15. For example, the flexible portion 14 is formed as a cantilevered piece connected to the peripheral edge of the through hole 15 in the first clamping body 10. The flexible portion 14 is formed to be deformable between a first deformation position (Figure 5) located inside the through hole 15 and a second deformation position (Figure 4) that extends into the internal space 1a. Here, the through hole 15 is formed in the first arc-shaped portion 11, and the flexible portion 14 is connected to one end and the other end in the circumferential direction of the peripheral edge of the through hole 15 of the first arc-shaped portion 11. Furthermore, this flexible portion 14 is formed to have an arc shape that follows the first arc-shaped surface 11a of the first arc-shaped portion 11 at the first deformation position, and to have an arc shape that is convex in the opposite direction to the first deformation position at the second deformation position. For example, this flexible portion 14 is deformed into the arc shape of the second deformation position by pushing it from the outside toward the internal space 1a at the first deformation position.

[0022] This clamp 1 holds the wire We1 or wire bundle Web1 of the largest diameter between the first clamping body 10 and the second clamping body 20 by positioning the first clamping body 10 and the second clamping body 20 in a closed state at the maximum wire holding position, and positioning the flexible portion 14 in a first deformed position within the through hole 15 (Figures 1 and 2). In the clamp 1 shown here, the wire We1 or wire bundle Web1 of the largest diameter is clamped between the first arc-shaped surface 11a of the first clamping body 10 and the second arc-shaped surface 21a of the second clamping body 20. For this reason, the first arc-shaped surface 11a and the second arc-shaped surface 21a are formed in an arc shape with a radius of curvature equal to or greater than that of the wire We1 or wire bundle Web1 of the largest diameter.

[0023] Furthermore, this clamp 1 holds the smallest diameter wire We2 or wire bundle Web2 between the flexible part 14 of the first clamping body 10 and the second clamping body 20 by positioning the first clamping body 10 and the second clamping body 20 in a closed state at the minimum wire holding position, and positioning the flexible part 14 in a second deformed position within the internal space 1a (Figures 3 and 4). In the clamp 1 shown here, the smallest diameter wire We2 or wire bundle Web2 is held between the flexible part 14 of the first clamping body 10, the second plane 13a of the first clamping body 10, and the second arc-shaped surface 21a of the second clamping body 20.

[0024] Furthermore, the clamp 1 holds the electric wire We 3 or electric wire bundle Web 3 by positioning the first clamping body 10 and the second clamping body 20 in a closed state at the maximum wire holding position, and positioning the flexible portion 14 in a second deformed position within the internal space 1a, thereby clamping it between, for example, the flexible portion 14 of the first clamping body 10 and the second arc-shaped surface 21a of the second clamping body 20 (Figure 6).

[0025] Furthermore, the clamp 1 holds the electric wire We 4 or electric wire bundle Web 4 by positioning the first clamping body 10 and the second clamping body 20 in a closed state at the minimum wire holding position, and positioning the flexible portion 14 in a first deformed position within the through hole 15, thereby clamping it between, for example, the first arc-shaped surface 11a of the first clamping body 10 and the third plane 22a of the second clamping body 20 (Figure 7).

[0026] This clamp 1 has a coupling structure 40 that connects the other ends of the first clamping body 10 and the second clamping body 20 in the closed state at the maximum wire holding position and the minimum wire holding position, respectively, in order to maintain the first clamping body 10 and the second clamping body 20 at the maximum wire holding position and the minimum wire holding position, respectively (Figures 1 to 5).

[0027] This coupling structure 40 comprises a first coupling body 41 provided at the other end of the first clamping body 10 and a second coupling body 42 provided at the other end of the second clamping body 20 (Figures 1 to 5). The coupling structure 40 connects the other ends of the first clamping body 10 and the second clamping body 20 by fitting the first coupling body 41 and the second coupling body 42 together. In this clamp 1, the end of the second connecting portion 13 opposite to the first arc-shaped portion 11 becomes the other end of the first clamping body 10, and the end of the fourth connecting portion 23 opposite to the second arc-shaped portion 21 becomes the other end of the second clamping body 20. For this reason, in this clamp 1, the first coupling body 41 is provided at the end of the second connecting portion 13, and the second coupling body 42 is provided at the end of the fourth connecting portion 23, and these ends are connected by the coupling structure 40.

[0028] This coupling structure 40 connects the other ends of the first clamping body 10 and the second clamping body 20 at the maximum wire holding position by fitting the first coupling body 41 and the second coupling body 42 at the first fitting position (Figures 1 and 2), and connects the other ends of the first clamping body 10 and the second clamping body 20 at the minimum wire holding position by fitting the first coupling body 41 and the second coupling body 42 at the second fitting position (Figures 3 and 4).

[0029] Specifically, this coupling structure 40 includes a fitting projection 43 provided on one of the first coupling body 41 and the second coupling body 42 (Figures 1, 3, and 5). The first coupling body 41 and the second coupling body 42 are coupled with their respective smooth coupling surfaces 41a and 42a in surface contact (Figures 2, 4, and 5). For this reason, the fitting projection 43 is provided vertically from either the coupling surface 41a of the first coupling body 41 or the coupling surface 42a of the second coupling body 42.

[0030] Furthermore, this coupling structure 40 includes a first insertion portion 44 provided on the other of the first coupling body 41 and the second coupling body 42, into which a fitting projection 43 is inserted to connect the first clamping body 10 and the second clamping body 20 at the maximum wire holding position, and a second insertion portion 45 provided on the other of the first coupling body 41 and the second coupling body 42, into which a fitting projection 43 is inserted to connect the first clamping body 10 and the second clamping body 20 at the minimum wire holding position (Figures 1, 3, and 5). The first insertion portion 44 and the second insertion portion 45 are through holes or grooves provided on the coupling surface 41a of the first coupling body 41 and the coupling surface 42a of the second coupling body 42, respectively.

[0031] When the other ends of the first clamping body 10 and the second clamping body 20 are joined at the maximum wire holding position, the fitting projection 43 and the first insertion portion 44 of this joining structure 40 are fitted together (Figure 1). On the other hand, when the other ends of the first clamping body 10 and the second clamping body 20 are joined at the minimum wire holding position, the fitting projection 43 and the second insertion portion 45 of this joining structure 40 are fitted together (Figure 3).

[0032] Here, the first connector 41 is provided with a fitting projection 43, and the second connector 42 is provided with a first fitting portion 44 and a second fitting portion 45 (Figure 5).

[0033] The first connecting body 41 shown here protrudes from the end of the second connecting portion 13 with its connecting surface 41a perpendicular to the second plane 13a (Figure 5). In this first connecting body 41, two fitting protrusions 43 protrude from its connecting surface 41a. These two fitting protrusions 43 are spaced apart from each other in directions perpendicular to their own protruding direction and the protruding direction of the first connecting body 41. Here, the two fitting protrusions 43 are each formed as identical cylindrical protrusions.

[0034] Furthermore, the second connector 42 shown here has its connecting surface 42a positioned on the same plane as the fourth plane 23a and protrudes from the end of the fourth connecting portion 23 (Figure 5). This second connector 42 is provided with two through-hole-shaped first insertion portions 44 and two second insertion portions 45 perpendicular to its connecting surface 42a. In this second connector 42, the two second insertion portions 45 are provided on the fourth connecting portion 23 side, and the two first insertion portions 44 are provided at a location further from the fourth connecting portion 23 than the two second insertion portions 45 in the protruding direction of the second connector 42. The two first insertion portions 44 and the two second insertion portions 45 are each spaced apart from each other in a direction perpendicular to the axis of their own holes and the protruding direction of the second connector 42. Here, two first insertion portions 44 and two second insertion portions 45 are each formed as identical cylindrical through holes.

[0035] This clamp 1 is fixed to the clamp target with screws to restrict the path of the electric wire We or electric wire bundle Web and to prevent interference with surrounding components. In this clamp 1, the first connecting body 41 and the second connecting body 42 of the coupling structure 40 are fixed to the clamp target with screws, thereby not only fulfilling the purpose of attaching to the clamp target but also maintaining the fitted state of the first connecting body 41 and the second connecting body 42.

[0036] Specifically, the first connector 41 has a first through hole 51 (Figure 5). The second connector 42 has a second through hole 52 (Figures 1, 3, and 5). One of the first and second through holes 51 is formed as a circular through hole through which the male screw portion 61 (Figures 1 to 4) is inserted. The other of the first and second through holes 52 is formed as an oval through hole through which the male screw portion 61 is inserted at both the first and second fitting positions of the first and second connectors 41 and 42. The first and second connectors 41 and 42 are screwed and fixed to the clamp target using the male screw portion 61 at either the first or second fitting position.

[0037] The first through-hole 51 shown here is a circular through-hole located between the two fitting protrusions 43 (Figure 5). The second through-hole 52 shown here is an oval through-hole with the protruding direction of the second connector 42 being the longitudinal direction, and is located between the two first fitting portions 44 and between the two second fitting portions 45 (Figures 1 to 5).

[0038] In this clamp 1, the male threaded portion 61 of the male threaded member 60 is inserted through the first through hole 51 and the second through hole 52 and screwed into the female threaded portion of the part to be clamped. As a result, when the first connecting body 41 and the second connecting body 42 are in the first fitting position (i.e., the first clamping body 10 and the second clamping body 20 are in the maximum wire holding position), the clamp 1 is fixed to the part to be clamped, and the first clamping body 10 and the second clamping body 20 are kept in the maximum wire holding position (Figures 1, 2, and 6). In this clamp 1, if the flexible portion 14 is positioned in the first deformation position within the through hole 15, the holding state of the wire We1 or wire bundle Web1 of the maximum diameter can be maintained (Figures 1 and 2), and if the flexible portion 14 is positioned in the second deformation position within the internal space 1a, the holding state of the wire We3 or wire bundle Web3 can be maintained (Figure 6). Furthermore, when the first connector 41 and the second connector 42 are in the second fitting position (i.e., the first clamping body 10 and the second clamping body 20 are in the minimum wire holding position), the clamp 1 is fixed to the clamp fixing target, and the first clamping body 10 and the second clamping body 20 are kept in the minimum wire holding position (Figures 3, 4, and 7). In this case, if the flexible part 14 is positioned in the second deformation position within the internal space 1a, the clamp 1 can maintain the holding state of the minimum diameter wire We2 or wire bundle Web2 (Figures 3 and 4), and if the flexible part 14 is positioned in the first deformation position within the through hole 15, the clamp can maintain the holding state of the wire We4 or wire bundle Web4 (Figure 7).

[0039] Furthermore, if there are other clamps around it that hold a common electric wire We or electric wire bundle Web, this clamp 1 may be screwed to the clamp-fixing target after it has been attached to the clamp-fixing target, or it may be screwed to the clamp-fixing target before it has been attached to the clamp-fixing target, depending on how those clamps are attached to the clamp-fixing target.

[0040] As described above, the clamp 1 of this embodiment can be assembled to electric wires We or wire bundles Web of different diameters. Furthermore, this clamp 1 can suppress rattling of the electric wires We or wire bundles Web within the internal space 1a for each electric wire We or wire bundle Web of different diameters. For this reason, even with electric wires We or wire bundles Web of different diameters, this clamp 1 can achieve route control and interference countermeasures with surrounding components with simple assembly work.
