Electrical component
View Patent ↗An electrical component comprises a main body, a fulcrum portion and at least two terminals including a first terminal and a second terminal. Each of the terminals has a first portion and a second portion. The first portion of one of the first terminal and the second terminal is brought into contact with a circuit board when the main body is tilted relative to the circuit board with the fulcrum portion, which acts as a fulcrum, under an insertion state where the terminals are inserted into through-holes, respectively, while none of the terminals are soldered thereto. When the main body is tilted relative to the circuit board with the fulcrum portion, which acts as the fulcrum, under the insertion state, the second portion of one of the first terminal and the second terminal is brought into contact with the circuit board to regulate an excessive tilt of the main body.
1. An electrical component mountable on a circuit board having at least two through-holes, wherein:
the electrical component comprises a main body, a fulcrum portion and at least two terminals;
the fulcrum portion is brought into contact with the circuit board when the electrical component is mounted on the circuit board;
when the main body is mounted on the circuit board, the at least two terminals are inserted into the at least two through-holes, respectively, and are soldered thereto;
the at least two terminals include a first terminal and a second terminal;
the first terminal and the second terminal are positioned apart from each other in a predetermined direction;
each of the terminals has a first portion and a second portion;
the first portion has an outer edge and an inner edge in the predetermined direction;
the outer edge of the first portion extends downward in an up-down direction perpendicular to the predetermined direction from the main body and then extends downward in the up-down direction and inward in the predetermined direction;
the outer edge of the first portion has an upper end in the up-down direction;
the upper end of the outer edge of the first portion is positioned at an outermost location of the outer edge of the first portion in the predetermined direction;
the first portion of one of the first terminal and the second terminal is brought into contact with the circuit board when the main body is tilted relative to the circuit board with the fulcrum portion, which acts as a fulcrum, under an insertion state where the terminals are inserted into the through-holes, respectively, while none of the terminals are soldered thereto;
the second portion extends downward in the up-down direction from the first portion; and
when the main body is tilted relative to the circuit board with the fulcrum portion, which acts as the fulcrum, under the insertion state, the second portion of one of the first terminal and the second terminal is brought into contact with the circuit board to regulate an excessive tilt of the main body.
2. The electrical component as recited in claim 1 , wherein:
the inner edge of the first portion has an upper end in the up-down direction;
the terminal has an innermost portion which is positioned at an innermost location of the terminal in the predetermined direction; and
the upper end of the inner edge of the first portion is positioned outward beyond the innermost portion in the predetermined direction.
3. The electrical component as recited in claim 2 , wherein:
the through-hole has an inner wall; and
the upper end of the inner edge of the first portion is spaced apart from the inner wall of the through-hole in the predetermined direction under the insertion state.
4. The electrical component as recited in claim 1 , wherein:
the terminal has an upper bulge;
the upper bulge is bulged outward in the predetermined direction;
the first portion has an upper end in the up-down direction; and
the upper bulge forms the upper end of the first portion.
5. The electrical component as recited in claim 1 , wherein:
the second portion has a lower bulge; and
the lower bulge is bulged inward in the predetermined direction.
6. The electrical component as recited in claim 1 , wherein:
the second portion has a lower protrusion; and
the lower protrusion protrudes outward in the predetermined direction.
7. The electrical component as recited in claim 6 , wherein:
the lower protrusion has a guide portion;
the guide portion intersects with both the predetermined direction and the up-down direction; and
the guide portion faces outward in the predetermined direction and downward in the up-down direction.
8. The electrical component as recited in claim 1 , wherein:
in the predetermined direction, the first portion of the terminal has a size smaller than a size of the through-hole corresponding thereto;
in a right-left direction perpendicular to both the predetermined direction and the up-down direction, the first portion of the terminal has a size smaller than a size of the through-hole corresponding thereto;
in the perpendicular direction, the second portion of the terminal has a size smaller than the size of the through-hole corresponding thereto; and
in the right-left direction, the second portion of the terminal has a size smaller than the size of the through-hole corresponding thereto.
9. The electrical component as recited in claim 1 , wherein a center of gravity of the electrical component is positioned inward in the predetermine direction beyond the fulcrum portion when the first portion is brought into contact with the circuit board while the second portion is brought into contact with the circuit board to regulate the excessive tilt of the main body.
