Description

[Technical field]

[0001] The present invention relates to a fixing structure for a cable tie used, for example, when fastening a cable to a housing of an electronic device with the cable tie. [Background technology]

[0002] A cable tie is often used to bundle a plurality of electric wires arranged inside an electronic device. Conventional cable tie fixing structures for bundling and fixing a plurality of electric wires with a cable tie are described in, for example, Patent Document 1 and Patent Document 2. The cable tie fixing structure shown in Patent Document 1 includes a rectangular hole formed in a plate-shaped base and a hook portion extending from the opening edge of the hole into the hole. In this cable tie fixing structure, first, the cable tie is wrapped around the hook portion to be temporarily fixed, and then the electric wire placed on the hook portion is placed. Then, the hook portion and the electric wire are bundled with a cable tie, and the cable tie is tightened to fix the electric wire to the hook portion.

[0003] The cable tie fixing structure disclosed in Patent Document 2 has a hole for inserting the cable tie formed in the housing of an electronic device and a guide groove for guiding the cable tie into the hole. According to this cable tie fixing structure, the cable tie is temporarily fixed by passing the cable tie through the hole for inserting the cable tie along the guide groove, and then the electric wires are placed on the cable tie and tightened, thereby fixing the electric wires to the housing with the cable tie.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-229283 [Patent Document 2] Patent No. 4042654 Summary of the Invention [Problem to be solved by the invention]

[0005] In the cable tie fixing structure disclosed in Patent Document 1, when the cable tie is hung on the hook, it is inserted from above, so the tip of the cable tie may slip out of the hole in the base, resulting in poor workability. In the cable tie fixing structure disclosed in Patent Document 2, the cable tie can be held in a guide groove, but a space is required to form the guide groove, which makes it difficult to miniaturize the cable tie fixing structure. This type of cable tie fixing structure cannot be used if the space to form the guide groove cannot be secured.

[0006] To provide a fixing structure for a cable tie that can easily bundle and fix electric wires without compromising workability, even in an electronic device where the space for fixing the electric wires with a cable tie is narrow. [Means for solving the problem]

[0007] In order to achieve this object, the fixing structure for a cable tie of the present invention comprises a wall along which an electric wire runs, and a protrusion formed in a gate-like cross section having a space through which the cable tie can be inserted and protruding from the wall, the protrusion having a first protrusion protruding from the wall, a second protrusion protruding from the wall at a position spaced from the first protrusion in a direction perpendicular to the longitudinal direction of the electric wire, and a connecting portion connecting the protruding end of the first protrusion and the protruding end of the second protrusion, the connecting portion having a binding portion extending in the longitudinal direction of the electric wire.

[0008] In the fixing structure of the cable tie of the present invention, the second convex portion may be provided at a position spaced apart from the first convex portion in the longitudinal direction of the electric wire, and the binding portion may be positioned between the first convex portion and the second convex portion in a direction perpendicular to the longitudinal direction, and may be connected to the first convex portion and the second convex portion via a connecting portion.

[0009] In the fixing structure of the cable tie according to the present invention, one end of the fastening portion may be provided at the same position as the first convex portion, and the other end of the fastening portion may be connected to the second convex portion via an extension portion. Effect of the Invention

[0010] In the present invention, the cable tie is extended in the longitudinal direction of the electric wires and passed through the space inside the convex body from the direction along the wall, and then the cable tie is rotated relative to the convex body to change its position, thereby making it possible to bind and fix the electric wires to the binding part with the cable tie. Therefore, according to the present invention, it is possible to provide a cable tie fixing structure that can easily bundle and fix electric wires without compromising workability even in electronic devices with limited space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, one embodiment of a fixing structure for a cable tie according to the present invention will be described in detail with reference to Figs. The cable tie fixing structure 1 shown in FIG. 1 is a structure for fixing an electric wire 3 to a housing 2 of an electronic device with a cable tie 4. Only a part of the housing 2 is depicted in FIG. 1. The housing 2 is made of a plastic material and has a bottom wall 2a along which the electric wire 3 runs, and a first vertical wall 5 and a second vertical wall 6 erected on the bottom wall 2a. The first vertical wall 5 and the second vertical wall 6 extend in one direction while being parallel to each other. The distance between the first vertical wall 5 and the second vertical wall 6 is such that an operator (not shown) can insert his / her index finger and thumb.

[0013] The electric wires 3 are laid on the bottom wall 2a with the direction in which the first and second vertical walls 5, 6 extend as the longitudinal direction, and are fixed by the cable tie 4 to a protrusion 7 of the bottom wall 2a, which will be described later. 3 and 4, the protrusion 7 is formed in a gate-like cross section having a space S through which the cable tie 4 can be inserted, and is provided in a protruding manner on the bottom wall 2a. The protrusion 7 according to this embodiment is integrally formed with the bottom wall 2a by integral molding, and is composed of first and second protrusions 8, 9 protruding from the bottom wall 2a, and a connection part 10 connecting the protruding ends of the first and second protrusions 8, 9. The bottom wall 2a is formed with a hole 11 through which a die (not shown) for molding the space S is passed.

[0014] The second protrusion 9 is disposed at a position spaced apart from the first protrusion 8 in a direction perpendicular to the longitudinal direction (the vertical direction in FIG. 2 ) of the electric wire 3. The second protrusion 9 according to this embodiment is also disposed at a position spaced apart from the first protrusion 8 in the longitudinal direction of the electric wire 3. The connection portion 10 has a binding portion 12 that extends linearly in the longitudinal direction of the electric wire 3. This binding portion 12 is positioned between the first protrusion 8 and the second protrusion 9 in a direction perpendicular to the longitudinal direction of the electric wire 3. One end of the binding portion 12 is connected to the first protrusion 8 via a first connecting portion 13, and the other end is connected to the second protrusion 9 via a second connecting portion 14. The first connecting portion 13 and the second connecting portion 14 each extend in a direction perpendicular to the longitudinal direction of the electric wire 3.

[0015] In order to fix the electric wires 3 to the binding portion 12 by the fixing structure 1 for the cable tie 4 configured in this manner, first, as shown in Fig. 5(A), the cable tie 4 is moved parallel to the longitudinal direction of the electric wires 3 while being aligned along the bottom wall 2a in a position extending in the longitudinal direction of the electric wires 3, and the tip of the cable tie 4 is inserted between the first convex portion 8 and the second convex portion 9. Then, as shown in Fig. 5(B), the cable tie 4 is passed through the space S inside the convex body 7 so that both ends of the cable tie 4 are exposed outside the convex body 7.

[0016] Next, one end and the other end of the cable tie 4 are grasped and lifted from the bottom wall 2a, and the cable tie 4 is rotated with respect to the convex body 7 from the initial position shown by the two-dot chain line A in Fig. 6(A) and (B) as shown by the solid line. At this time, the position of the cable tie 4 is changed until the cable tie 4 intersects with the binding portion 12 as shown by the two-dot chain line B in Fig. 6(A). After that, the electric wire 3 is placed on the convex body 7, and the cable tie 4 is fastened so as to bind the convex body 7 and the electric wire 3, thereby fixing the electric wire 3 to the convex body 7 (bottom wall 2a). Therefore, the electric wire 3 can be fixed to the bottom wall 2a by the cable tie 4 in the narrow space sandwiched between the first vertical wall 5 and the second vertical wall 6. In addition, the cable tie 4 is moved in the longitudinal direction of the electric wire 3 and rotated, so that the tip of the cable tie 4 can be prevented from slipping out of the hole 11 to the outside of the bottom wall 2a. Therefore, according to this embodiment, it is possible to provide a fixing structure for a cable tie that can easily bundle and fix electric wires without compromising workability even in electronic devices where space is limited.

[0017] (Modification of convex body) The convex bodies can be formed into the shapes shown in Figures 7 to 9. In Figures 7 to 9, members that are the same as or equivalent to those described with reference to Figures 1 to 6 are given the same reference numerals and detailed description thereof will be omitted as appropriate.

[0018] The first protrusion 8 and the second protrusion 9 of the protrusions 21, 22 shown in Figs. 7 and 8 are formed at the same position in a direction perpendicular to the longitudinal direction of the electric wire 3 (the left-right direction in Figs. 7 and 8). The connection portion 10 of the protrusion 21 shown in Fig. 7 is formed in a Z-shape in a plan view. In the protrusion 21 shown in Fig. 7, the binding portion 12 is positioned between the first protrusion 8 and the second protrusion 9. One end of the binding portion 12 and the first protrusion 8 are connected by a first connecting portion 13, and the other end of the binding portion 12 and the second protrusion 9 are connected by a second connecting portion 14.

[0019] The connection portion 10 of the convex body 22 shown in Fig. 8 is formed in a U-shape in a plan view. The convex body 22 shown in Fig. 8 is formed by a first binding portion 23 extending from the first convex portion 8 in the longitudinal direction of the electric wire 3, a second binding portion 24 extending from the second convex portion 9 in the same direction as the first binding portion 23, and a U-shaped connecting portion 25 connecting the tip of the first binding portion 23 and the tip of the second binding portion 24. In this convex body 22, the electric wire 3 can be bound by hanging a cable tie 4 on either the first binding portion 23 or the second binding portion 24.

[0020] The first protrusion 8 and the second protrusion 9 of the protrusion 26 shown in Fig. 9 are spaced apart both in the longitudinal direction of the electric wire 3 and in a direction perpendicular to the longitudinal direction of the electric wire 3. The connection portion 10 of this protrusion 7 is formed in an L-shape in a plan view. One end of the fastening portion 12 of this protrusion 7 is provided at the same position as the first protrusion 8. The other end of the fastening portion 12 is connected to the second protrusion 9 via an extension portion 27. Even in the case of the convex bodies 21, 22, and 26 shown in Figures 7 to 9, the cable tie 4 can be passed through the electric wires 3 in the longitudinal direction and then rotated so that it intersects with the binding portions 12, 23, and 24, so that electric wires can be easily bundled and fixed without compromising workability even in electronic devices with limited space.
