Patent ID: 8500472

Claim:
A connector to be mounted on a board, comprising: a housing having an insertion space into which a thin insertion object is inserted; a first terminal member configured to be pushed by the thin insertion object to be elastically deformed when the thin insertion object is inserted into the insertion space; a second terminal member, having a supported portion supported by the housing, an elastic portion configured to be pushed by the first terminal member to be deformed according to deformation of the first terminal member, and a terminal portion to be soldered to the board, the terminal portion being extended from the supported portion in a direction different form an extending direction of the elastic portion, and; a sectional area reducing part, provided in the second terminal member between the supported portion and the terminal portion, and having a sectional area smaller than a sectional area at the terminal portion, wherein an insertion state of the thin insertion object is detected based on a change of conduction between the first terminal member and the second terminal member, the sectional area reducing part is defined by a notched portion formed by notching a part of the second terminal between the terminal portion and the supported portion in a width direction of the terminal portion, the housing has a terminal covering portion covering an outer side of the terminal portion, a groove through which the second terminal member is exposed is provided at the terminal covering portion, and the notched portion is disposed at the groove so that a solder flowing up along the groove is retained in the notched portion.
