In this case, the terminal pin is formed in a hollow circular cross section, characterized in that the diameter can be adjusted to match the diameter of the external terminals inserted therein.

 In this case, the terminal pin includes a first pin portion having a first diameter in the longitudinal direction, and a second pin portion having a second diameter smaller than the first diameter and a partial region protruding outward through one end of the terminal; The first pin part may have side ends parallel to each other in the longitudinal direction.

In this case, the first pin portion of the terminal pin may be formed by rolling a plate.

In addition, the insulator includes a first insulator having a first support hole into which the first pin part is inserted, and the first pin part is provided with a pair of elastic surfaces in which some regions facing each other are cut inward. The first support hole of the first insulator may have a contact protrusion protruding to be inserted into the elastic surface.

In addition, the insulator includes a second insulator including a second support hole into which the second pin part is inserted, and a locking jaw is formed in the second pin part, and the hook is caught in the second support hole of the second insulator. Some areas may be stepped to interfere with the jaw.
