STRUCTURAL ASSOCIATIONS OF A PLURALITY OF MUTUALLY-INSULATED ELECTRICAL CONNECTING ELEMENTS; COUPLING DEVICES; CURRENT COLLECTORS ## Abstract A connector terminal (10) is provided with a housing (14) for slidably guiding the connector terminal (10) over a conductive surface (92) of a board side terminal (90), and a spring piece (34) supported by the housing (14) so as to resiliently contact the conductive surface (92), and the spring piece (34) is configured in such a manner that a contact portion (48) of the spring piece (34) moves into a path of movement of the conductive surface (92) to serve as a contact portion (48) for electric contact with the board side terminal (90) as a pressing portion (46) of the spring piece is pressed by the conductive surface (92) owing to a sliding movement of the connector terminal (10) relative to the board side terminal (90). ## Claims ### Claim 1 A connector terminal configured to be electrically connected to an object terminal by making a sliding engagement with a planar surface including the object terminal, the connector terminal comprising: a housing configured to slide over the object terminal; and a spring piece connected to the housing, the spring piece including a pressing portion which is configured to be located outside of the housing in a free state of the spring piece, and to move into the housing owing to an elastic deformation of the spring piece when the pressing portion is pressed by the planar surface, and a contact portion which is configured to be located inside of the housing in the free state of the spring piece, and to move out of the housing and make an electric contact with the object terminal as the pressing portion moves into the housing. ### Claim 2 (depends on 1) The connector terminal as defined in claim 1, wherein the object terminal comprises a board side terminal formed in a printed circuit board and having a conductive surface constituting the planar surface. ### Claim 3 (depends on 1) The connector terminal as defined in claim 1, wherein the housing comprises a support portion supporting a portion located between the pressing portion and the contact portion of the spring peace as a fulcrum, the pressing portion serving as an effort point, and the contact portion serving as a load point. ### Claim 4 (depends on 3) The connector terminal as defined in claim 3, wherein the support portion comprises a sloping surface rising toward the pressing portion of the spring piece, and the spring piece is pivotally supported by the housing at an intermediate portion of the spring piece serving as a fulcrum and located between the pressing portion and the contact portion, and slidably engaged by the sloping surface. ### Claim 5 (depends on 4) The connector terminal as defined in claim 4, wherein the housing comprises a rectangular bottom piece and a pair of side vertical pieces extending along either side edge of the bottom piece, and the support portion comprises an opening provided in each side vertical piece, and the intermediate portion of the spring piece comprises an extension extending laterally from the spring piece and engaged by the opening. ### Claim 6 (depends on 1) The connector terminal as defined in claim 1, wherein the pressing portion is configured to serve as an additional contact point for electric contact with the object terminal when the pressing portion is pressed by the planar surface. ### Claim 7 (depends on 1) The connector terminal as defined in claim 1, wherein the housing comprises a slot defined by a rectangular bottom piece and a pair of side vertical pieces extending along either side edge of the bottom piece, the contact portion being configured to be received in the slot in the free state of the spring piece. ### Claim 8 (depends on 1) The connector terminal as defined in claim 1, wherein the spring piece comprises a base end portion fixedly attached to the housing, and extends from the base end portion toward the pressing portion in a sliding direction in relation to the object terminal, and is folded back so as to extend from the pressing portion to the contact portion in an opposite sliding direction in relation to the object terminal. ### Claim 9 (depends on 1) The connector terminal as defined in claim 1, wherein the housing and the spring piece are formed as a single integral member. ### Claim 10 (depends on 1) A method of manufacturing the connector terminal as defined in claim 1, comprising: a blanking step of blanking a sheet material into a blank having a developed flat shape containing an entirety of the connector terminal; and a bending step of bending the blank into the connector terminal.
