PCT No. PCT/JP97/02804 Sec. 371 Date Feb. 23, 1998 Sec. 102(e) Date Feb. 23, 1998 PCT Filed Aug. 11, 1997 PCT Pub. No. WO99/08494 PCT Pub. Date Feb. 18, 1999An external connection mechanism of a printed-circuit board 1 has a U-shaped elastic metal piece 2 having two parallel legs adapted to receive one edge of a printed-circuit board 1 therebetween. An insulating terminal base 3 holds both the metal piece 2 and an electric terminal 4 while keeping them in contact. The printed-circuit board 1 carries a temperature sensor 13 which is connected to a temperature-responsive circuit of the board 1. A contact lug 6 is formed by bending one of the two legs so as to be engageable with a conductive portion of the board 1, and a temperature-measuring station 7 is formed by bending root portion of the other one of the two legs toward close vicinity of the electric terminal 4 so as to be engageable with the temperature sensor 13. When the board 1 is received by the metal piece 2, the contact lug 6 engages the conductive portion of the board 1 so as to bring the electric terminal 4 into operative contact with the printed-circuit board 1 and the temperature sensor 13 engages the temperature-measuring station 7 so as to measure temperature substantially at the electric terminal 4.
