M265803

[Technical field to which the new type belongs] The present invention relates to an electrical connector, especially a type of soldering on a printed circuit board inside a pin terminal board. The electrical connection on the printed circuit board can be firmly fixed before the foot is connected. Device. ° [Previous technology] Connectors and imprints in the field of telecommunications are electrically connected with holes on another system. The tops of the conductive ends in this special body should be round holes. The bottom of the body should be welded with other external force. The round holes can be separated from the electrical connector printed circuit welding position. Refer to 1 991 for the sub-printed electricity in the round hole. After the conductivity is extended horizontally, it will work with the sub-surface and externally, and it will cause the conductive end plate to move inaccurately. The method is terminal connection. In December, the circuit board was used to print the printed circuit of the printed circuit board formed by the terminal package. The conductive end of the circuit made the soldering sub-weld to cause electrical connection. The electrical connector and connector components were soldered to the printed circuit board. There are two types of electrical connection: one is a surface welding method, and the end is directly welded to the surface of the printed circuit board; that is, the end of the conductive terminal is inserted into the printed circuit and related to the creation of the electrical connector. US Patent No. 5,069,641 'Including the insulating body and the insulating printed circuit board. The sub printed circuit board includes a plurality of circular holes and connecting electrical connectors. The external printed circuit board includes a base located in a vertical direction and a tail from the base. . The bottom end of the base part extends from the circuit board for soldering. In the case of an arrangement, it becomes more difficult for the conductive board to move from the daughter board due to the movement of the electrical connector or the tail of the daughter board. In addition, in the conventional technology, it is easy to make conductive terminals on the sub printed circuit board when the conductive terminals are on the sub printed circuit board.
