Abstract: In order to prevent a fixing terminal from being dislocated from regular-mounting-position on a connector main body when force is applied from outside before placed on a substrate, a surface-mounted connector including a connector main body to be placed on a substrate, a fixing terminal that is temporarily fixed to a side wall of the connector main body by being press-fitted, along the side wall, from a side opposite to that in which the connector main body is placed on the substrate, and that, in the temporarily fixed state, is soldered to the substrate, thereby allowing the connector main body to be mounted on the substrate, and shielding walls provided integrally with the connector main body alongside the fixing terminal in the temporarily fixed state so as to correspond to the fixing terminal, and preventing the fixing terminal in the temporarily fixed state from being interfered from outside, is provided.

Abstract: An upper tier terminal is provided with a fitting portion and a board attachment portion. When the upper tier terminal is being fabricated, a first wire member which is a component of the fitting portion and a second wire member which is a component of the board attachment portion, whole peripheral surfaces of which have been subjected to a plating treatment beforehand, are employed. End portions of the first wire member and the second wire member are mutually superposed, and the first wire member and the second wire member are joined. Thus, the fitting portion is formed and the board attachment portion is formed. Hence, a surface of the upper tier terminal is structured by a plating layer at the peripheral surface of the first wire member and a plating layer at the peripheral surface of the second wire member. Consequently, a post-plating treatment can be rendered unnecessary.

Abstract: A connector enables a size reduction while maintaining a function of reliably preventing terminal members from falling out of terminal holes. In this connector, a plate spring piece is provided in a terminal hole of a connector housing, with a length thereof set to an axial direction of the terminal hole, and an engaging pawl protrudes from the plate spring piece. When a female terminal is inserted into the terminal hole, the engaging pawl engages with the female terminal and bends the plate spring piece downward, enabling the insertion. When the female terminal is inserted to a predetermined depth in the terminal hole, the plate spring piece returns and the engaging pawl moves into an engaging hole of the female terminal. The plate spring piece has a structure of which one length direction end portion and one side portion, along the length direction, are fixed to the connector housing.

Abstract: A connector in which a housing and a retainer are coupled with sufficient strength when the connector is reduced in scale. In this connector, provisional anchoring pieces and main anchoring pieces are provided at two end portions of an inner peripheral wall of an insertion hole formed in the housing, with lengths along a direction that intersects a direction of insertion of the retainer into the insertion hole. At outer sides of two end portions of the retainer, anchorage pawls, which are formed to be engageable with the main anchoring pieces and the provisional anchoring pieces, are provided with lengths along the intersecting direction. With this structure, when the retainer is inserted into the insertion hole of the housing, the anchorage pawls engage, at two end portions of the connector, with the provisional anchoring pieces and with the main anchoring pieces.

Abstract: In a terminal manufacturing method of the present invention, first a thin plate-like body including a thin plate-like terminal portion and a thin plate-like leg portion is formed with a die. The thin plate-like terminal portion has a shape corresponding to a terminal portion 24 of an upper-level terminal 22 and a terminal portion 30 of a lower-level terminal 28. The thin plate-like leg portion has the shape corresponding to a leg portion 26 of the upper-level terminal 22 and a leg portion 32 of the lower-level terminal 28. Then, the upper-level terminal 22 is formed by bending the thin plate-like leg portion toward one side of a plate-thickness direction. Also, the lower-level terminal 28 is formed by bending the thin plate-like leg portion toward the other side of the plate-thickness direction. Thus, by simply changing the bending direction of the thin plate-like leg portion, either the upper-level terminal 22 or the lower-level terminal 28 can be formed.

Abstract: A female terminal, into which a male terminal is inserted and connected, is formed in a shape of a substantially square tube. Respective one portions, in an axial direction and between corner portions, of a ceiling wall, a floor wall, and a pair of left and right side walls, which are four wall portions, are plate spring portions which contact the male terminal while elastically deforming independently of one another. Because the wall portions themselves structure the plate spring portions, there is no need to provide a plate spring within a tube wall, and the female terminal can be made compact. Further, contact pressure is ensured because the respective plate spring portions contact the male terminal from different directions.

Abstract: A connector has terminals, each having a tip end portion. A wiring board has through holes. A land is provided on the wiring board about each through hole. When the connector is mounted on the wiring board, each terminal is connected to one of the lands with a part of the tip end portion being located in the corresponding through hole. The ratio of the cross-sectional area of each tip end portion to the cross-sectional area of each through hole is at least 0.11 and no more than 0.89. This improves the reliability of the joint portions between the terminals and the wiring board.

Abstract: A method for connecting a connector to a printed-circuit board that maintains the optimal terminal alignment accuracy and improves the terminal soldering reliability. The method includes forming a fastener for fastening the terminals from a metal having a fusion point that is substantially the same as solder, fastening the terminals at predetermined positions with the fastener in a state in which the terminals are accurately aligned to one another, inserting the terminals into the through holes, and releasing the terminals by fusing the fastener.

Abstract: A lever (14) is pivotally movably supported on a female connector (11). In accordance with the movement of a slide member (13) relative to the female connector (11), the lever (14) is pivotally moved while held in engagement with a tongue portion (29b) of an engagement portion (29) formed on a male connector (16), and with this construction the inserting force is reduced. When the slide member (13) is completely drawn out relative to the female connector (11), an engagement projection (14g) of the lever (14) is engaged with an engagement claw (26a) of an elastic arm portion (26), and the lever (14) is held in this position. When a projection (29a) of the engagement portion (29) elastically deforms the elastic arm portion (26), the retained condition of the lever (14) is canceled, so that the lever (14) is allowed to be pivotally moved.

Abstract: A projection (9) is provided in a male connector (1). A lever (16) is rotatably provided in a female connector (2). The lever (16) has a curved groove (18). When the lever (16) is turned, the projection (9) is inserted into the groove (18). As the projection (9) is inserted into this groove (18), the connection between the male connector (1) and the female connector (2) is strengthened. At that time, the lever (16) provides leverage. Moreover, the distance between the fulcrum for this lever and a point of action gradually decreases. Furthermore, in this case, the groove (18) is formed in such a way as to extend to the turning center portion of the lever (16), so that the distance between the fulcrum for the lever and the point of action is reduced still more. Consequently, a larger connecting force can be provided thereto.

Abstract: A plurality of steps respectively constituted by inner housings (19) are incorporated into an outer housing (18) of a female connector (12). Moreover, a pushing operation force transmitting member (20) is incorporated there into. The engaging relation of this pushing operation force transmitting member (20) to each of the inner housings is changed every time this member is externally operated. Thus, a pushing operation force applied to the outer housing (18) is transmitted to the inner housings (19) sequentially. Consequently, the outer housing (18) and the pushing operation force transmitting member (20) are alternately pushed. Thus, the plurality of steps respectively constituted by the inner housings (19) are sequentially connected to a male connector (12).
