The first terminal grooves 11 and the second terminal grooves 12 constitute terminal grooves. Locking grooves 13 are formed on both sides of the insulating body 10, and fitting grooves 14 are formed outside the locking grooves 13 of the insulating body 10.

  The first terminal 20 and the second terminal 30 described above include a solder pin 21 and a solder pin 31, respectively. The first terminal 20 is inserted into the first terminal groove 11 of the insulating body 10, and the solder pin 21 is the insulating body 10. And is soldered onto a circuit board (not shown). The second terminal 30 is inserted into the second terminal groove 12 of the insulating body 10, and the solder pin 31 is located on the bottom surface of the insulating body 10 and is soldered to the circuit board. The first terminal 20 and the second terminal 30 constitute the above-described terminal.

  Each of the fixing means 40 includes a base portion 41, a solder portion 42 that is bent and extended downward from one end of the base portion 41, and an extending portion 43 that is extended, bent upward, and extended. . Two locking portions 44 are extended from the other ends of the base portion 41, and the ends of the locking portions 44 are bent outward and extended to form hooks 45, and one side of the base portion 41 is bent and extended. A locking wall 46 is formed, and a locking projection 47 is provided at the end of the locking wall 46. Please refer to FIG. The width of the locking groove 13 is larger than the thickness of the base portion 41 of the fixing means 40, so that the fixing means 40 is movably inserted into the locking groove 13 of the insulating body 10 to the upper limit, and the locking portion 44 is Locked in the locking groove 13, the hook 45 is locked to one end surface of the insulating body 10, the locking projection 47 is in contact with one end surface of the insulating body 10, and the solder portion 42 is on the bottom surface of the insulating body 10. To position.
