The contact 200 and the first and second connection terminals 300a and 300b can be connected to the substrate 410 of the substrate assembly 400 at a time by simply inserting each into the circuit 412. Therefore, the number of assembling steps can be reduced, and the cost of this connector can also be reduced in this respect.

  In addition, the connection portion 210 of the contact 200 is placed in the first connection hole 411 of the substrate assembly 400, and the connection portions 320a and 320b of the first and second connection terminals 300a and 300b are placed in the second connection hole 412 of the substrate assembly 400, respectively. When inserting, the pulse transformer 420 of the substrate assembly 400 is accommodated in the accommodating recess α of the holder 100. In other words, at the same time as connecting the connection part 210 of the contact 200 and the connection parts 320a and 320b of the first and second connection terminals 300a and 300b to the first connection hole 411 and the second connection hole 412 of the substrate assembly 400, The pulse transformer 420 of the assembly 400 can be housed in the housing recess α of the holder 100. Therefore, also in this respect, it is possible to reduce the man-hours for assembling the connector. In addition, since the pulse transformer 420 of the board assembly 400 is accommodated in the accommodating recess α of the holder 100, the size of the connector can be reduced.
