  Conventionally, in order to open and close the engaging portion in a support for fixing an electric wire through which a high-voltage current flows, some tools such as a screwdriver and a sputter have been required. Certainly, the use of tools can provide strong clamping, but the work process required is complicated, and the number of parts such as bolts, nuts, washers, and chassis is large, and work efficiency has been significantly reduced. . In particular, work in confined places such as the inside of distribution boxes was inconvenient. On the other hand, as a method of improving work efficiency without using tools, a method of adopting a flexible lock mechanism as described in the above-mentioned patent document has been proposed. Certainly, the engaging means using the bending performance of a material such as plastic is easy to fix. However, this type of structure has an extremely weak engaging force against impact, and is not suitable for a wire support through which a high-voltage current flows, particularly as in the present invention, due to insufficient strength.

  In view of the above-mentioned problems of the conventional wire support, the present inventors have secured the wire in a neat and reliable manner without the need for tools such as a screwdriver or a wrench when holding and fixing the wire through which a high-voltage current flows. An object of the present invention is to provide an electric wire support having a strong structure excellent in impact resistance that can be pinched and fixed.

  That is, in the present invention, the main body of the electric wire support that holds and fixes the electric wire is composed of the lower support portion, the upper support portion, and the clamp portion. One end of the lower support portion and the upper support portion facing each other is connected by a connecting portion constituting a hinge function, and the other end facing each other is formed by an engagement portion with a fitting clamp portion with a claw.

  The electric wire support according to the present invention can easily open and close the lock function at the engaging portion by simply sliding the clamp portion with the force of a finger without the need for tools such as a screwdriver when pinching the electric wire. Moreover, it has been reached that the electric wire can be pinched and fixed securely.

  The electric wire support according to the present invention forms a recess for holding the electric wire in the opposite direction on the abdominal surfaces of the lower support portion and the upper support portion, and stops and holds the ring surface that contacts the connecting portion at an arbitrary opening / closing angle. For this purpose, protrusions that fit together are formed. Also, a pair of projections and depressions that fit on the joint surfaces that contact when the upper and lower support portions are closed, and further, a clamp groove that conforms to the shape of the clamp portion is formed on the outer periphery of the upper and lower support portions. It consists of the upper and lower support parts.

  On the other hand, the clamp portion is formed by a cylindrical piece that is integrally formed with the finger-hanging portion, and is formed by an engaging claw that is bent inward on both sides of the cylindrical piece.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, an electric wire support will be described with reference to the drawings for embodiments of the present invention.

In FIG. 1, reference numeral A denotes a wire support body, which includes a lower support portion 1, an upper support portion 2, and a clamp portion 4 that are processed with a synthetic resin material such as polypropylene resin or ABS resin. Reference numeral B denotes a leg attached to the lower support portion 1 in order to attach the wire support body A to the object.
And the lower support part 1 and the upper support part 2 of the electric wire support main body A form an arbitrary half-moon-shaped depression for holding the electric wire in the opposite direction on the abdominal surface of the support part, and one end facing each other functions as a hinge. It is formed with the connection part 3 which comprises. The hinge of the connecting portion 3 forms a structure such as a combination of a convex strip portion and a dovetail groove engaged with the convex strip portion or a combination of a plug-in shaft and a ring cylinder engaged therewith. As long as the connection part 3 comprises the lower support part 1 and the upper support part 2 which face each other here as a support axis and comprises the function of opening and closing freely, it may be what kind of mechanism, and is not restrict | limited in particular. However, the opening angle of the lower support part 1 and the upper support part 2 is arbitrarily opened to at least 160 degrees exceeding 90 degrees from the workability of electric wire attachment, and is stopped and held at several opening / closing angles. It is preferable to form a mechanism. For example, as shown in FIG. 2, a projection 6 and a mechanism for engaging with the projection 6 are formed on the ring surface 5 ′ of the ring cylinder 5 with which the upper and lower support portions 1 and 2 abut as the connecting portion 3.

  Furthermore, there is a pair of concave and convex portions 7 ′ that are fitted to each other on the joint surface 7 of both support portions that contact when the upper and lower support portions 1 and 2 are closed with the connecting portion 3 as a support shaft. It is provided. When the support portion is closed, the concave-convex portion 7 ′ is formed with a fitting, thereby preventing the lower support portion 1 and the upper support portion 2 from being displaced or twisted due to an external impact. Furthermore, a clamp groove 8 is formed along the shape of the clamp portion 4 on the outer periphery of the joint surface 7 of both support portions.

  As shown in FIG. 3, the clamp portion 4 is formed of a cylindrical piece 10 in which a finger rest portion 9 is integrally formed so as to be fitted into clamp grooves 8 on the outer periphery of the lower support portion 1 and the upper support portion 2. Both sides of the cylindrical piece 10 are formed with engaging claws 11 bent inward. Further, drop-off preventing projections 12 and 12 ′ are formed on an arbitrary end face in contact with the clamp groove 8.

  In attaching the clamp portion 4, the cylindrical piece 10 of the clamp portion 4 is slid and inserted along the clamp groove 8. At that time, by forming a so-called snap-in mechanism in which the protrusion 12 for preventing the drop-off is fitted into the clamp groove 8, once the clamp part 4 is inserted, even if the clamp part 4 is slid in the groove, The clamp portion 4 is formed in a mechanism that does not easily fall off from the clamp groove 8. Further, even if the clamp part 4 slides too much in the clamp groove 8, the protrusion 12 'prevents the drop off.

  Corresponding to the position where one end of the clamp 4 is stopped, as shown in FIG. 4, a notch 13 is formed at one end of the joining surface 7 to which the upper and lower support portions engage, and the notch 13 The narrow portion W ′ is an introduction portion that can open and close the upper and lower support portions while avoiding the wide portion W of the cylindrical piece 10 of the clamp portion 4 that stops at one end of the slide groove 8. Then, the cylindrical portion 10 and the slide groove 8 are integrated with each other by slidingly inserting the clamp portion 4 closed at one end with the support portion closed along the clamp grooves 8 of the upper and lower support portions. An engaging portion is formed. At the same time, the engaging claw 11 that is bent inward on both sides of the cylindrical piece 10 acts to completely configure the locking mechanism in the engaging portion. That is, the electric wire support body A can be freely opened and closed by opening and closing the engaging portion.

  Moreover, it is also preferable to devise the wire support body A of the present invention so that the wire is sandwiched and fixed by interposing an adapter as necessary. The adapter is extremely effective as a spacer when sandwiching and fixing electric wires having different cross-sectional areas and so-called thicknesses. The adapter may be of any configuration such as a combination of a normal cylindrical shape and a semi-cylindrical shape, and is not particularly limited. However, it is preferable to devise such as providing a fitting groove in a part of the support portion so that the adapter does not fall when the wire support body A is opened.

The invention's effect

  As described above, in the wire support of the present invention, the wire support body is composed of the lower support portion, the upper support portion, and the clamp portion, and one end of the lower support portion and the upper support portion facing each other constitutes a hinge function. And the other one end facing each other is formed by an engaging portion formed by interposing a clamp portion, and thus the electric wire support body is integrally formed. Therefore, after the electric wire is held between the lower support portion and the upper support portion, it is sufficient to configure the engaging portion by inserting the cylindrical piece of the clamp portion into the slide groove of the support portion with the force of a finger. With this slide operation of the clamp part, the electric wire support body can be opened and closed freely by simply uniting or opening the lower support part and the upper support part, and the electric wire can be easily nipped and fixed or released. it can.

  Therefore, unlike the conventional wire support using bolts and nuts, the present invention does not require a tool such as a screwdriver or a sputter. Therefore, the process is also freed from complicated operations as in the prior art. In particular, the workability in a confined place is improved as compared with the comparison. In addition, the present invention can provide a wire support having a tough structure that is particularly necessary for pinching and fixing an electric wire through which a high-voltage current flows.
