Description

  The present invention relates to a wire rod connector, and more particularly to a wire rod connector for connecting a plurality of wire rods constituting a three-dimensional shaped object.

  Conventionally, as a three-dimensional structure to be installed indoors or outdoors for the purpose of appreciation or decoration, a three-dimensional skeleton is formed using a metal wire, and an LED (light emitting diode) is arranged on this skeleton. Known objects and monuments are known. This shaped object is generally formed by combining linear or curved wire rods and connecting them together by soldering to form an outer shape.

  The above prior art is a general matter, and the present applicant has no particular knowledge of the literature specifying the prior art at the time of the present application.

  However, when connecting a plurality of wire rods by soldering, it is very difficult to change the connection position such as fine adjustment after soldering. For this reason, in order to form a desired skeleton as a three-dimensional modeled object, it is necessary to determine the connection position of each wire while adjusting the overall balance, and to connect accurately each time. In particular, when connecting a curved wire, it is necessary to consider the bending direction of the wire in addition to positioning the connection position of the wire. These tasks are often based on the experiences of the creators, and are very difficult for inexperienced people and beginners.

  Therefore, in view of the above situation, the present invention provides a wire connection that can be easily performed even by a beginner or the like for connecting work of a wire that is performed when producing a three-dimensional model formed by a plurality of wires. Providing tools is an issue.

The means taken by the present invention to solve the above-mentioned problems are as follows:
“A plurality of support portions for connecting each of the plurality of wire rods, having a cylindrical shape into which each of the plurality of wire rods constituting the three-dimensional model can be inserted, and being crimped to the wire rod by plastic deformation. Wire rod connector "
It is.

  Here, the wire has sufficient strength to form the skeleton of the modeled object, and has a diameter of about 2 mm to 10 mm with a metal such as steel, copper, stainless steel, brass, or aluminum. The thing etc. which have are mentioned. Examples of the plastically deformable material include metals such as stainless steel, iron, brass, zinc, copper, and aluminum.

  The wire rod connector having the above-described configuration includes a plurality of support portions having a cylindrical shape through which the wire rod can be inserted. Furthermore, this support part is formed of a material that can be plastically deformed. Thus, the plurality of wire rods are formed on the plurality of support portions by plastically deforming the support portions so as to be crimped to the wire rods using a pinching tool such as pliers in a state where the wire rods are inserted through the plurality of support portions. The plurality of wires are fixed to each other and connected to each other.

  In this case, even when the support portion is not crimped to the wire, the state in which the wires are brought close to each other is maintained by inserting the plurality of wire rods through the plurality of support portions. Furthermore, in the state where it is not crimped, the wire connecting tool can be moved along the wire inserted through the support portion. For this reason, when it is necessary to connect the wire rods at a plurality of locations, the wire rods are brought close to each other at the respective connection locations using a plurality of wire rod connecting devices, and these wire rod connecting tools are arranged along the wire rods. After adjusting the whole balance by moving, it is also possible to connect the wire members by pressure-bonding each support part of each of the plurality of wire member connecting tools. As a result, it is not necessary to determine the connection positions of the wires for each line and to connect each time. Therefore, according to the wire rod connector having the above-described configuration, the wire rod connection work performed when producing a three-dimensional model formed by a plurality of wire rods can be easily performed even by a beginner or the like.

  The number of support parts is not particularly limited as long as it is two or more. In addition, the shape of the entire wire connecting tool is not particularly limited, and is formed one-dimensionally by arranging two support portions in series, and crossing two support portions. Examples include those configured two-dimensionally by arranging them, and those configured three-dimensionally by arranging three or more support portions in three dimensions. In particular, in the case of a configuration in which two support portions are arranged in series, the wires can be connected in the length direction.

  In addition, as described above, since the support portion is formed of a plastically deformable material, by changing the direction by plastically deforming the support portion, the direction of the fixed wire can be finely adjusted. Is possible. Therefore, it is possible to improve the workability of the model production.
