Since the shaped terminals are buried in a plurality of parallel arrangements, the floating capacitance increases as the distance between adjacent terminals decreases as the number of terminals increases. Also, in order to cope with this high density, when the terminal width is reduced, the self-inductance increases, and there is a disadvantage that crosstalk and ground noise are easily generated. Further, impedance matching with a printed board (for example, about 50Ω) ) Cannot be obtained. On the other hand, this connector has a drawback that the number of terminals is large and the multi-stage parallel arrangement is short-circuited, or a large number of assembly steps are required for repairing poor connection.

来る利点がある。As described above, the connector of the present invention does not provide a conventional independent L-shaped terminal, but provides an extension terminal portion for integrating each terminal, forms a slit at the distal end portion, and forms a predetermined space between each terminal. By forming a conductive portion through via holes formed in a zigzag pattern in a conductive film connected to the connector terminal in a portion of each terminal connected to the terminal of the printed board, There is an advantage that a required interval dimension is secured between the terminals and this interval can be maintained without causing deformation.

るばかりか、加工コストも低減するという利点がある。Also, when assembling, unlike the conventional case, there is an advantage that it is not necessary to insert the terminals one by one into the through-hole into the printed board, and the integrated terminal group can be mounted only once.
Further, the connection between the terminal and the through hole or between the via hole and the through hole can be realized by forming a conductive film or a conductive portion by a known printing technique. This has the advantage that not only the man-hour for assembling the connector is reduced, but also the processing cost is reduced.

クタが得られるという効果がある。As described above, according to the present invention, only a terminal portion that comes into contact with a pad of a printed board is separated at a predetermined interval, an extension terminal portion that integrates other portions is provided, and one end of a connector terminal is inserted into a housing. By forming a conductive portion for connecting the conductive film of the hole and each terminal to the extension terminal portion by using a printing technique, predetermined widths of the terminals and predetermined dimensions between the terminals can be secured, so that crosstalk and noise can be prevented. This is advantageous in that an inexpensive connector that can easily obtain impedance matching can be obtained.
