Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method for compressing a cylindrical sleeve for a twisted wire and a compressor used for plug-in connection of terminals of electric meters and switches. [Prior technology] From the past, there are direct connection and terminal insertion connection for the connection of electric wires. They are used separately according to the counterpart's electrical equipment, especially in the case of terminal insertion connection. Because the top end of the twisted wire must be integrated, it must be used. Perform a hard φ welding operation. However, the operation is inefficient due to the use of fire, and there is also a risk of fire and operation loss. In addition, the conventional cylindrical sleeve has a small contact area with the stranded wire, and it is easy to fall off when it is tilted downward during the pressing operation of the sleeve, causing obstacles in operation, and there is also a problem during subsequent repairs. Get rid of difficulties and other issues. Therefore, it is expected that a new type of twisted wire sleeve is developed. The shape and shape of the twisted wire sleeve and the twisted wire are suitable, and the contact area between the twisted wire and the sleeve is increased, the operation efficiency is high, and the resistance is high and the efficiency is high. . β However, the development of a sleeve that fits the shape of the stranded wire requires huge development costs and time, and there are many problems such as mass production in order to improve economic efficiency. In addition, as a reference of the existing type of compactor (compressor pliers), a component that can remove the compactor of the compactor to support various sleeves was invented, but it still has workability, economy, Problems such as durability. (For example, refer to Patent Document 1) Patent Document 1: JP 2000- 1 3340 1 200531392 [Summary of the Invention] In order to solve the above problems, the present invention has developed and provided a cylindrical sleeve compression method and a compressor for stranded wires. The existing cylindrical sleeve is inserted into a stranded wire and combined so that the outer peripheral portion of the sleeve is aligned with the outer circumferential surface of the stranded wire and compressed. As a mechanism for achieving this problem, the compressor of the present invention has a pair of handles, and a pair of jaws driven by the pair of handles. The center of the pair of jaws is provided with a cross-sectional outer shape suitable for a twisted wire and has Various types of predetermined widths • Paired compression parts, and can support multiple sizes of cylindrical sleeves, and the compression part of this compressor can be used to compress the entire outer peripheral surface of the cylindrical sleeve. The gap between the wire and the cylindrical sleeve is tight, which increases the contact area. As an effect of the present invention, an existing cylindrical sleeve is used for fixing the twisted wire, and the outer peripheral surface portion of the cylindrical sleeve is aligned with the outer circumferential surface of the twisted wire to compress the twisted wire and The tightness of the gap between the cylindrical sleeves increases the contact area. As a result, not only the work efficiency is improved, but also a connection method with low #resistance and high efficiency can be formed. In addition, since it has the following characteristics as the point of connection of the electric wire, it has extremely beneficial effects such as improving workability, durability, and safety. This feature is first of all for speedy and reliable operation, robustness, excellent mechanical strength, excellent electrical conductivity, easy release during repair, and reduction in electrical fires. [Embodiment] The best mode of the present invention is to judge based on the resistance-6- 200531392 'to make the gap between the stranded wire and the sleeve to the minimum to compress, but on the contrary when repairing When the workability is determined based on the workability, the workability is worse as the clearance is smaller. Therefore, the best method is to obtain a compression method and a compressor that can perform adaptive compression in consideration of both resistance and workability. Embodiment 1 If an embodiment of the present invention is described in detail with reference to Figs. 1 to 4, the details are as follows: · Insert the terminals of the power meter, the switch, etc. into the φ section and connect the twisted wires used to pass through the cylindrical shape. When the sleeve (S) is compressed, it is clamped by a cross compressor (1) for compression, and the stranded wire (SL) and the sleeve (S) are compressed and fixed. The above-mentioned cross compressor (1) is formed by compressing grooves having an appropriate cross-sectional outer shape of a stranded wire (SL) so as to face each other. In addition, terminals for electric meters, switches, and the like are inserted into a compressor of a cylindrical sleeve (S) for a twisted wire used in a connection portion. The compressor (1) is composed of a compressor for a twisted wire having the following characteristics. That is, the compressor (1) has a pair of handles (2), and a pair of jaws (3) for working with the pair of handles (2), and is provided at the center of the pair of #jaws (3) A plurality of pairs of compression portions (4) having a predetermined width (W) conforming to the cross-sectional outer shape of the stranded wire (SL), and can be used with a plurality of sizes of cylindrical sleeves (S). The compression part (1) of (1) compresses the entire outer peripheral surface of the cylindrical sleeve (S) to bring the stranded wire (SL) into contact with the cylindrical sleeve (S), thereby increasing the contact area. Big. In the following, the components and operation principle of the compressor (1) will be explained. First, as shown in Figs. 1 (A) and 1 (B), the component structure is roughly divided into a pair of handles (2) and a pair of jaws (3). The handles (2) can be divided into shaft portions ( la) 200531392 is opened and closed symmetrically on the left and right sides, and a compression force adjusting device (2a) having the following structure is provided as follows: The structure is such that the handles (2) are positioned approximately in the middle of the pair, and the handles are defined as follows. The force is compressed, and the handle is automatically returned to the open side when the specified pressure is reached. On the one hand, the pair of jaw portions (3) are provided at their center positions with three sizes of paired compression portions (4a), (4b), (4c). The compression portions (4a), (4b), (4c) ) Are formed into left-right symmetrical shapes corresponding to the cross-sectional shape of each strand. If the pair of handles (2) are compressed toward the closed side, the pair of compression portions (4) of the jaw (3) are closed to form a compression sleeve. Structure of the tube. A method for compressing the sleeve will be described below. First, Fig. 3 (A) shows the relationship between the stranded wire (SL), the cylindrical sleeve (S), and the compressor (1) before the sleeve is compressed, and Fig. 3 (B) shows the relationship between the sleeve after compression Relation diagram of stranded wire (SL), cylindrical sleeve (S ') and compressor (1). The total length of the cylindrical sleeve (S) is about 20 mm, and the width W of the compression part (4) of the compressor (1) is 12 mm. Therefore, the compression part (4) of the compressor (1) is used to cover the cylindrical sleeve. The entire outer peripheral surface of the barrel (S) is divided into two parts for full compression. As a result, the gap between the stranded wire (SL) and the cylindrical sleeve (S) is brought into close contact, and the contact area is increased. In addition, the compression section (4) of the compressor (1) is divided into three types, namely, a small compression section (4a), a medium compression section (4b), and a large compression section (4c), and each time it is used according to its purpose. However, the size and number of the compression portions are not limited to three types. The shape can be changed depending on the purpose and application. In addition, Figure 2 (A) is a detailed enlarged view of Part A of Figure 1 (B), which shows the above-mentioned medium-sized compression section (4b); Figure 2 (B) is a reference material, which shows the applicable wires of the compressor. A list of specifications and the relationship between wire size and compression inner diameter size. 200531392 Furthermore, the cylindrical sleeve (s) is compressed at the end of the stranded wire (SL), and the tight part is inserted into the terminal part (Ma) of the electric meter (M) as shown in FIG. 4 In the middle, fasten and fix with small screws (Mb).
