Description

This invention relates to a floating connector and a connector connection structure. Patent Document 1 below describes a conventional connector. This connector comprises a housing, a plurality of first terminals, and a plurality of second terminals. The housing has a roughly rectangular insertion opening in plan view, a rectangular parallelepiped-shaped mating chamber, a plurality of first housing sections, and a plurality of second housing sections. The mating chamber is located below the insertion opening and communicates with the insertion opening. The plurality of first and second housing sections are provided on the first and second inner walls of the mating chamber in the short direction of one and the other, and communicate with the mating chamber. Each of the multiple first terminals has a base end, a substrate connection portion, a first elastic arm, a first contact portion, a second elastic arm, and a second contact portion. The base end is housed and held within a first housing portion of the housing. The substrate connection portion extends from the base end in one direction along its shorter side, with its tip located outside the housing and connectable to a substrate. The first elastic arm extends upward from the base end. The second elastic arm is positioned inward relative to the first elastic arm and extends upward from the base end. The length of the second elastic arm is smaller than the length of the first elastic arm. The first contact portion is located at the tip of the first elastic arm and protrudes from the first housing portion in the other direction along its shorter side, and is located within the mating chamber. The second contact portion is located at the tip of the second elastic arm, positioned below the first contact portion with a gap between them, and protrudes from the first housing portion in the other direction along its shorter side, and is located within the mating chamber. Each of the multiple second terminals has a base end, a substrate connection portion, a first elastic arm, a first contact portion, a second elastic arm, and a second contact portion. The base end is housed and held within the second housing portion of the housing. The substrate connection portion extends from the base end in the other direction in the short side, with its tip located outside the housing and connectable to a substrate. The first elastic arm extends upward from the base end. The second elastic arm is positioned inward relative to the first elastic arm and extends upward from the base end. The length of the second elastic arm is smaller than the length of the first elastic arm. The first contact portion is located at the tip of the first elastic arm and protrudes from the second housing portion in one direction in the short side, and is located within the mating chamber. The second contact portion is located at the tip of the second elastic arm, positioned below the first contact portion with a gap, and protrudes from the second housing portion in one direction in the short side, and is located within the mating chamber. When the intermediate circuit board is inserted into the mating chamber through the connector's insertion opening, the first and second contact portions of the multiple first terminals are elastically contacted from one side in the short direction, and the first and second contact portions of the multiple second terminals are elastically contacted from the other side in the short direction. This electrically connects the intermediate circuit board to the connector and holds it in a tiltable position in the short direction.
