Abstract

PROBLEM TO BE SOLVED: To prevent the signal noise or oscillation in the high frequency transmission by fitting an earth plate to a connector part to which a high frequency transmission cable is connected, and connecting a shield wire of each transmission cable to the earth plate arranged on the connector to set the potential difference of each shield wire to be zero. SOLUTION: A core wire of a cable 6 for the high frequency transmission is conductive-connected to a pin 3 for connecting a cable side connector 1 through soldering or crimping. An earth wire 7 of a cable for high frequency transmission of the cable for the high frequency transmission is connected and fixed to a conductive earth of the cable side connector 1 so as to be conductive. The earth wire 7 is connected with the same potential difference. A conductive earth 2 is connected to an earth part 11 of a printed circuit board 4 by a pin 9 for cable connector earth. Thus, the earth wire 7 of the cable 6 for high frequency transmission becomes of same potential difference, and the signal noise or oscillation is difficult to generate.

2. Description of the Related Art As shown in FIG. 2, a general resin molded connector includes a molded cable side connector 1 and a connector insertion pin 3. As shown in FIG. The connector insertion pin 3 contacts the printed circuit board side connector 5 from the connection side of the high-frequency transmission cable 6 to establish electrical continuity. After the printed circuit board side connector 5 is inserted into the through hole 8 on the printed circuit board 4 typified by a glass epoxy resin or a ceramic plate, it is fixed with a conductor such as solder. The connector insertion pins 3 are inserted into the printed circuit board side connector 5 fixed to the printed circuit board 4, and electrical connection is established by a spring in the printed circuit board side connector 5. The method of directly inserting the pins 3 of the cable-side connector 1 into the through holes 8 of the printed circuit board 4 and connecting them with a conductor such as solder has the same function. Reference numeral 6 denotes a connection cable for transmitting a high frequency, which employs a method in which a core wire is connected to the cable connector connection pin 3 of the cable side connector 1 by soldering or crimping and press-fitted into the cable side connector 1. Further, the high-frequency transmission cable ground wire 7 is directly soldered to the ground terminal surface 10 of the printed circuit board 4 or is connected by screwing with a lug terminal 12.

According to the present invention, in order to achieve the above object, an earth plate is attached to a connector portion for connecting a high-frequency transmission cable, and a shield wire of each transmission cable is connected to an earth plate provided on the connector. By setting the potential line of each shield line to zero, noise and oscillation are prevented. As a result, in the case of using a shielded wire or coaxial cable that is effective as a countermeasure against noise and oscillation in high frequency transmission, as an example, shield the external signal from the core wire connected to the connector by crimping or soldering and the surrounding area. There is a braided line to do. On the other hand, noise and oscillation can be prevented by arranging ground wires around the cable connector, connecting these braided wires to the connector ground, and making each shield wire the same potential.
