Description of the Invention: [Technical Field of the Invention] The present invention relates to a connector and a body used for the connector. [Prior Art] The present invention relates to a connector and a body used for the connector. In the related art, as disclosed in Japanese Laid-Open Patent Publication No. H07-157594 (hereinafter referred to as Patent Document 1), a resin casing and a plurality of coaxial cables that hold a plurality of contacts are provided. And the plug housing installed in the outer casing. In Patent Document 1, the contacts are exposed from the outer casing, and the terminal portions are arranged side by side in the longitudinal direction of the outer casing, and the core wires of the coaxial cable are welded to the respective terminal portions to connect the coaxial cable and the contacts. Electrical connection. The coaxial cable is used as a signal line or a power line. In Patent Document 1, a coaxial cable having a core of the same diameter is used. SUMMARY OF THE INVENTION However, as in the prior art described above, when a coaxial cable having a core wire of the same diameter as that of a coaxial cable for a signal line is used as a power supply line, a plurality of coaxial cables must be used. As a result, the number of coaxial cables used is increased, and there is a problem that the connector is enlarged. Therefore, it has been proposed to use a cable having a core wire (thick core wire) having a larger diameter than other core wires (thick core wires) as a power cable. At this time, even if the thick core wire is to be welded to the terminal portion formed by the thin core wire-welded shape -5 to 201212435, since the width of the terminal portion is narrow, the thick core wire and the narrow terminal portion cannot be easily welded. There are doubts that cause poor conduction. Therefore, in consideration of the state in which the thick core wire is placed between the adjacent two narrow-width terminal portions, the thick core wires are respectively welded to the two terminal portions, and the thick core wires are electrically connected to the respective terminal portions. However, when the thick core wire is placed between two adjacent narrow-width terminal portions, the thick core wire comes into contact with the outer casing having poor solderability, and the distance between the thick core wire and each terminal portion becomes long. Therefore, when the thick core wire and the terminal portion are welded, the solder on the outer casing may fall off, and the thick core wire and the terminal portion may not be welded, and there is a concern that the conduction failure may occur. Accordingly, an object of the present invention is to provide a connector which can be made compact and which can suppress the conduction failure of the thick core wire and the terminal portion, and a body used for the connector. In order to achieve the above object, the present invention is a connector comprising: a plurality of cables; and a body in which a plurality of terminal portions are arranged side by side, and the terminal portion is connected to one of the plurality of cables; The core wire is characterized in that the plurality of cables are provided with: an i-th cable having a thin core wire and a second cable having a thick core wire; and the thick core wire of the second cable is placed on the body The two terminal portions are connected to each other between the adjacent terminal portions, and a groove portion of the thick core wire on which the second cable is placed is formed between the adjacent terminal portions of the main body. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. the following

In the upper portion of the thin core wire 2 1 a or the thick core wire 2 2 a, as described above, in the present embodiment, it is formed between the adjacent terminal portions 51 of the main body 30 in which a plurality of terminal portions 51 are arranged side by side. In the groove portion 35, the thick core wire 22a of the thick coaxial cable 22 is placed in the groove portion 35, and the thick core wire 22a of the thick coaxial cable 22 is connected to the two terminals. Part 51. Therefore, the thick core wire 22a can be shortened and adjacent

In other words, according to the present embodiment, it is possible to obtain a connector that can achieve miniaturization and suppress the conduction failure of the thick core wire 22a and the terminal portion 51, and the body 30 used in the connector 10. Further, according to the present embodiment, the groove portion 35 is inclined such that the side surface portions 35b opposed to each other are narrowed in width in the depth direction from the opening 35a of the groove portion 35. As described above, the inclined surface is formed by inclining the pair of side surface portions 35b, and when the thick core wire 22a is placed on the groove portion 35, the outer circumference of the thick core wire 22a can be brought into contact with the pair of side surface portions (inclined surface) 3 5b. . Therefore, the thick core wire 22a can be positioned by the side portion (inclined surface) 35b, and the thick core wire 22a can be easily welded to the terminal portion 51 without performing the alignment of the thick core wire at the time of welding. Further, since the positional deviation of the thick core wire 22a can be suppressed, it is possible to suppress the case where the thick core wire 2 2 a is welded to the one side of the terminal portion 5 1 side due to the positional deviation. As described above, when the position is shifted, the other terminal portion 5 1 whose distance from the thick core wire 2 2 a becomes longer may cause a conduction failure. However, as in the present embodiment, when the pair of side surface portions 35b are inclined to form an inclined surface, the thick core wire 2 2 a can be positioned by the side surface portion (inclined surface) 3 5 b, so that the thick core wire 2 2 can be a is placed at almost the middle portion of the adjacent terminal portion 51. Therefore, the distance between each terminal portion 5 1 to the thick core wire 2 2 a can be made almost the same, and the thick core wire 2 2 a and the terminal portion (the other terminal portion when the one terminal portion side is biased) can be suppressed. Poor conduction caused. Further, in the present embodiment, since the side -13 - 201212435 face portion 5 1 b of the adjacent terminal portion 5 1 is exposed in the groove portion 35, the molten solder can be made to flow into the groove portion 35 during welding. As a result, the welding of the thick core wire 22a and the terminal portion 51 can be surely performed, and the conduction failure between the thick core wire 22a and the terminal portion 51 can be further suppressed. Further, in a state where the thick core wire 22a is placed on the groove portion 35, the outer circumference of the thick core wire 22a is brought into contact with the side surface portion 51b exposed in the groove portion 35, whereby the thick core wire 22a and the terminal are Between the portions 51, the resin body 30 can be welded without intervening. As a result, the welding of the thick core wire 2 2 a and the terminal portion 5 1 can be performed more reliably. Further, since the tin can be formed on the surface 5 1 a side of the terminal portion 51 and the side surface portion 5 1 b side, the soldering of the thick core wire 22a and the terminal portion 5 1 can be surely performed, and the solder 70 can be used. The joint strength between the thick core wire 22a and the terminal portion 51 is raised (refer to Fig. 7). Further, according to the present embodiment, the thin core wire 21a of the thin coaxial cable (first cable) 21 is placed on the surface 51a of the terminal portion 51 and the thick coaxial cable (second cable) 22 is thick. The core wire 22a is placed in the state of the groove portion 35 such that the thin core wire 2 1 a of the thin wire coaxial cable 2 1 is spaced from the surface 5 1 a of the terminal portion 5 1 by the distance from the thick core wire 22a of the thick wire coaxial cable 22 The height of the surface 51a of the terminal portion 51 is substantially the same. Therefore, it is easy to place a solder wire or a solder paste or the like on the upper portion of the thin core wire 21a and the thick core wire 22a. Therefore, one-time welding of the plurality of thin core wires 2 1 a and the thick core wires 22a can be easily performed. Further, by aligning the upper core height of the thin core wire 2 1 a and the thick core wire 2 2 a, it is possible to perform welding of the plurality of thin core wires 21a and the thick core wires 22a at a time using a tool such as a solder coater having a flat surface. That is, it is not necessary to process the surface of the machine such as the solder coating machine (the part that is in contact with the solder), and even if the thickness of the core wire is different, the existing machine can be used for the one-time welding. Further, the shape of the groove portion is not limited to those exemplified in the above embodiment, and a groove portion having various shapes may be formed. A modification of the groove portion will be described below. In the following plural modifications, the same constituent elements as those of the above embodiment are included. Therefore, in the following, the same components are given the same reference numerals and the description thereof is omitted. (First Modification) The groove portion 35A of the present modification includes the side surface portion 3 5 b as shown in Fig. 5 . The side surface portion 3 5 b opposite to the bottom surface portion 3 5 c is formed substantially perpendicularly. Further, the side surface portion 51b of the terminal portion 51 is covered by the body portion 31. The side surface portion 51b of the terminal portion 51 is not exposed to the groove portion 35A. When the groove portion 3 5 A is formed and the thick core wire 2 2 a is placed on the groove portion 35 A, the distance between the thick core wire 22a and the adjacent terminal portion 51 can be shortened. Therefore, according to the present modification, almost the same effects and effects as those of the first embodiment described above can be achieved. (Second Modification) As shown in Fig. 6, the groove portion 35B of the present modification includes a side surface portion 35b and a bottom surface portion 35c, and the side surface portions 35b opposed to each other are formed substantially perpendicularly. Further, in the present modification, the side surface portions 5 1 b -15 - 201212435 of the terminal portion 51 are exposed in the groove portion 35B, by exposing the side surface portion 51b of the terminal portion 51 to the groove portion 35B. As shown in Fig. 7, the solder 70 can be made to flow into the side surface of the groove portion 35B. As a result, the welding of the thick core wire 2 2 a and the terminal portion 5 1 can be surely performed, and the conduction between the thick core wire and the terminal portion 5 1 can be further suppressed. Further, since the tantalum tin can be formed on the surface 5 1 a side of the terminal portion 51 and the side surface portion 5 b side, the soldering of the thick core wire 2 2 a and the terminal portion 5 i can be surely performed, and can be performed by The solder 70 is used to increase the bonding strength between the thick core wire 22a and the terminal portion 51 (refer to Fig. 7). Therefore, according to the present modification, almost the same effects and effects as those of the first embodiment described above can be achieved. (Third Modification) As shown in Fig. 8, the groove portion 35C of the present modification includes a side surface portion 35b and a bottom surface portion 35c, and the side surface portions 35b opposed to each other are formed substantially perpendicularly. Further, the side surface portion 51b of the terminal portion 51 is exposed to the inside of the groove portion 35C. In the present modification, the chamfered portion is formed on the upper portion of the side surface portion 51b opposite to the adjacent terminal portion 51. 5 1 c. When the thick core wire 22a is placed on the groove portion 35C, the outer circumference of the thick core wire 22a abuts against the chamfered portion 5 1 c, respectively. According to the above modification, the same effects and effects as those of the first embodiment described above can be achieved. Further, according to the present modification, since the phase of the adjacent terminal portion 5 1
