PROBLEM TO BE SOLVED: To provide a multipole connector by which even an ultrasonic probe increased in the number of electrodes is constituted with a small number of components, assembled with a few assembly man-hours and given reduced electric crosstalk, and a high- performance ultrasonic diagnostic device is constituted at low cost. SOLUTION: A receptable contact part 3-a as one end of a plug terminal 3 is provided partially with a projection shape, so machined as to enable electric conduction by the contact of the projection part with the other conductor part by mechanical movement in the projection direction to the other conductor part, and finished to surface roughness standing contacting of thousands to tens of thousands of times. A connector contact part 3-b is electrically connected by the insertion of the connector terminal 7 of a fitting connector from the connector contact part end direction of the lug terminal 3, mechanically held, and finished to surface roughness withstanding insertion and extraction of hundreds to thousands of times, and surface treatment such as gold plating is carried out when necessary. Then another connector 7 to be engaged is provided on the opposite receptable terminal side of the plug terminal 3 and inserted from the opposite receptable terminal end of the plug terminal 3 to enable electric connection and mechanical holding. |
