Description

1288995 V. INSTRUCTIONS (1) 1. Techniques of the Invention The present invention relates to the connection of a cable and the like. [Prior Art] As described above, the electrical connectors of the electrical connection are required to be electrically connected. The core of the cable. In this case, it is cooked from the past. Bulletin No. 3 3 8 3 2 2 2) This outlines the electrical connector for the cable. The majority of the contact members are formed in the same contact line in the same groove in the receiving groove, and the entire core wire can be connected to the core wire corresponding to the bottom surface of the heating plate. And electrical connectors for cables and connecting cables. For the cable, each connection will be connected to the D. The end of the neatly connected piece of electrical power is abutted. However, the contact piece is soldered and the electric cable is arranged. Most of the cables are connected to the core cable. "Although any of the various types of electrical connectors have been previously connected to one of the methods associated with their respective electrical and cable cores (see, for example, the cable disclosed in Japanese Patent No. 3382022) The electrical connector used is a receiving groove of the supporting member made of insulating material. If the top surface of the supported connecting portion is 'loaded electric', the alignment is on the same plane. The upper end surface of the biting wire is for the core wire. The squid joint is used for the whole batch of soldering and soldering. [Inventive content] I know that the near-caller connector that I want to solve is more and more miniaturized and multi-polarized, and the contact piece has the requirement of two narrow spacing methods. Solder joint connection contact =, 卞才口芯

1288995 V. INSTRUCTIONS (2) When the wire is used (the pitch of the contact piece is narrowed and the area of the soldering is also reduced), the excess soft solder will flow out to the adjacent core wire, which easily forms a short circuit and has a connection reliability problem. After that. In view of this problem, an object of the present invention is to provide an electrical connector for a connecting cable having high connection reliability, in which a core of a plurality of contacts and a plurality of cables corresponding thereto are soft in a multi-pole electrical connector When soldered, it prevents short circuits between adjacent core wires. Means for Solving the Problem In order to achieve the object, the present invention is an electrical connector for connecting a cable (for example, the plug electrical connector p in the present embodiment), which is made of a supporting member made of an insulating material (for example, in this embodiment) The plug side supporting member 10) supports a plurality of contact members (for example, the plug contact member 40 in the embodiment) so as to be aligned at regular intervals, and respectively solders the core wires of the cable to the contacts. A cable (for example, the cable assembly C in this embodiment) is connected to the top surface of the portion, and a groove is formed on the top surface of the support member between the contacts. Further, it is preferable that the groove has a length corresponding to a portion of the cable connecting portion where the core wire is soldered. Further, it is preferable that the groove is formed by penetrating the support member up and down. Moreover, it is preferable that the positioning guides projecting upward and supporting both sides of the core wire are formed at the rear of the groove, respectively, in a state where the core wire is placed on the top surface of the cable connecting portion, Align the upper end of the core

EFFECTS OF THE INVENTION According to the above-described problem solving, the present invention can provide an electrical connector for connecting a cable which can prevent short circuit between adjacent core wires and achieve higher connection reliability. Further, it is preferable that the groove has a length corresponding to a portion of the cable connecting portion where the core wire is soldered. With this configuration, it is possible to effectively suppress the excess soft solder from being enlarged from the portion to be soldered, and to prevent a short circuit between adjacent core wires. Further, it is preferable that the groove is formed by penetrating the support member up and down. With this configuration, since excess soft solder flows into the grooves penetrating the upper and lower sides of the supporting member, the occurrence of a short circuit between adjacent core wires can be surely prevented. Further, it is preferable that a positioning guide portion that protrudes upward and supports both sides of the core wire is formed at a rear portion of the groove, so that the core wire is placed on the top surface of the cable connecting portion, so that the core wire is placed on the top surface of the cable connecting portion The upper ends of the core wires are aligned at the same height. According to this configuration, since the upper ends of all the core wires are aligned on the same plane by the positioning guide portions, all the core wires can be heated by the same heater chip, and the entire batch can be soldered to the cable connecting portion. Fourth Embodiment [Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments in accordance with the present invention will be described with reference to the drawings.
