Claim of US Patent No. 10,251,296

1. A clip to be soldered to a conductive portion of a printed wiring board, the clip comprising:a base portion having a plate shape and including a joining portion soldered to the conductive portion;
at least two holding portions each comprising a pair of spring pieces including a first spring piece and a second spring piece connected to the base portion and facing each other, and disposed side-by-side allowing an insert having a plate shape inserted between the first spring piece and the second spring piece to be sandwiched from a front surface side and a rear surface side; and
two guiding portions extending from different positions of the base portion to face each other, and configured to guide the insert to a position between the first spring piece and the second spring piece,
the first spring piece and the second spring piece constituting the at least two holding portions each including a first portion extending in a direction that intersects the base portion, and a second portion connected in a bent manner to an end portion of the first portion opposite to an end portion connected to the base portion, and extending in a direction toward the corresponding spring piece of the pair of spring pieces as well as in a direction approaching the base portion, and configured to be elastically displaceable in a facing direction, the facing direction being a direction in which the first spring piece and the second spring piece are disposed side-by-side,
the two guiding portions each including a contact surface configured to guide the insert toward a position between the first spring piece and the second spring piece in a case where the insert moves in an insertion direction and the guiding portion comes into contact with the insert, and a contact surface support portion that supports the contact surface, the insertion direction being the direction of movement of the insert from a state of not being sandwiched to a state of being sandwiched by the first spring piece and the second spring piece,
the contact surface provided to each of the two guiding portions being disposed between the at least two holding portions in relation to the direction the at least two holding portions are disposed side-by-side,
the contact surface being at least partially, in relation to the insertion direction, in a position farther away from the base portion than the second portion of at least one of the first spring piece or the second spring piece and, in relation to the facing direction, in a position farther away from the corresponding spring piece than the second portion of the pair of spring pieces,
the base portion being provided with a suction surface for a case where the clip is suctioned by a suction nozzle, in a region between the two guiding portions, and
each of the contact surface support portion of the two guiding portions and the first portion being connected by a connecting portion.
