Abstract: After bringing a conductor of an electric wire into press contact to connect with a wire caulking portion of a connection terminal, the conductor and the wire caulking portion are welded to connect by irradiating laser beam to a bottom wall of the wire caulking portion. With this construction, the hard plating layer fractures the passivation layer upon press-fastening of the conductor-clamping portion on the conductor part of the wire, thereby providing the good press-clamping condition in which any passivation layer, increasing the contact resistance, is not interposed between the press-clamping terminal and the conductor part.

The boss is disposed in a component mounting area surrounded by an outer periphery of the plurality of component mounting portions in a plan view. The housing includes a reference surface to restrict the electrical connection portion, with a portion of the terminal fitting abutting the reference surface, from being further inserted into the insertion hole. At least one boss for maintaining a distance between the bottom plate of the case and the top plate of the cover is provided on the case or the cover. Abstract: A method of connecting a terminal fitting and an electric wire, includes the steps of: providing a terminal fitting; providing an electric wire in which a core wire is covered with an insulating sheath; providing a conductive connecting member formed with an insertion hole; inserting the electric wire into the insertion hole of the connecting member; compressing the connecting member radially inwardly so as to caulk an inserted portion of the electric wire uniformly over a whole periphery thereof; and welding the connecting member and the terminal fitting by applying ultrasonic wave. A component including a terminal is assembled in the component mounting portion from above the cover. The connector includes a terminal fitting including an electrical connection portion to be connected to a mating terminal of the mating connector, a housing including an insertion hole, the electrical connection portion inserted through the insertion hole and a rear holder attached to the housing such that the rear holder presses and holds the terminal fitting against the housing. The electrical connection box includes a case having a bottom plate having a terminal connection portion, a cover having a top plate and assembled by being covered on an upper portion of the case, and a plurality of component mounting portions provided on the top plate of the cover. Abstract: A female connector terminal into which a rectangular male connector terminal is to be inserted includes a hollow conductor having a rectangular engagement portion for inserting the male connector terminal; a protrusion arranged at the engagement portion of the conductor and brought into contact with the male connector terminal; and a plate spring arranged at the conductor engagement portion to face the protrusion so as to sandwich the male connector terminal together with the protrusion. Thereafter, the conductive portion is inserted and fitted into the terminal, and then the conductive portion, while pressed by a pressing vibration horn, is bonded to the terminal by ultrasonic vibrations applied from the pressing vibration horn. Abstract: A method of joining a wire includes the steps of: providing the wire having a conducting portion consisting of a plurality of core wires, restricting a width of the conducting portion, pressing the core wires of the conducting portion restricted in the restricting step, and joining the pressed core wires of the conducting portion each other so that the conducting portion is integrally formed into a flat plate-shape. Laser irradiation is carried out intermittently by three times and the laser irradiation at the second time and thereafter which is carried out later is carried out such that during a time period in which a laser welded portion immediately previously is brought into a predetermined state of elevating temperature, portions or welded regions overlap welded regions in laser irradiation irradiated previously. The swing contributes to the absorption of the vibration or the like. Abstract: A connector is to be joined to a mating connector. A lower-side inner surface as a first inner surface defining the opening is provided with a plurality of conductive rotary members that rotate in a direction substantially perpendicular to a direction in which the plate-like terminal is inserted. The method includes the steps of storing a reference data of a relationship between displacements of the press contact blades when the wire is brought into press contact with a normal press contact terminal and contact loads between the press contact blades and the core wire; inserting the wire between the press contact blades of the press contact terminal as an object to be inspected; measuring the displacement of the press contact blades caused by the insertion of the wire; and determining the acceptability of the press contact terminal as the object to be inspected by predicting the contact loads between the press contact blades of the press contact terminal as the object to be inspected based on the measured displacements and the reference data. By the plate-like terminal being inserted into and pulled out from the bus bar, the rotary members receive force from the plate-like terminal and rotate within a plane substantially perpendicular to a direction in which the plate-like terminal is inserted and pulled out. Abstract: A press-clamping terminal of the invention is press-fastened at its conductor-clamping portion on an outer periphery of a conductor part of a wire so as to be electrically connected to the conductor part. The rear holder includes a pressing pin to press, when the rear holder is attached to the housing, the terminal fitting from a rear side of the terminal fitting such that the pressing pin is partially and plastically deformed and the terminal fitting is pressed against the reference surface. In the connector structure, a bus bar and a plate-like terminal mate with each other to establish an electric connection. The wire has a plurality of conductors covered with a insulating sheath. Abstract: A connector structure that can ensure connection is provided. Each corner portion formed by the each side wall and terminal base plate portion has a rounded shape in cross section. The terminal of the component assembled to the component mounting portion is connected to the terminal connection portion of the case. A plating layer is formed at least on an inner surface of the conductor-clamping portion for contact with the conductor part, the plating layer being harder than a passivation layer formed on a surface of the conductor part, and being excellent in electrical conductivity. It is also provided with a frame member that holds the rotary members and that is connected to the bus bar. Abstract: An electrical connection box is provided. Abstract: An apparatus of determining acceptability of a press contact terminal including press contact blades which are separated from each other when the wire is inserted between the press contact blades so that a core wire is electrically connected to the press contact terminal, includes: a storing unit which stores a reference data showing a relationship between displacements of the blades when the wire is brought into press contact with a normal one of the terminal and contact loads between the blades and the core wire; an inserting unit which holds the terminal and inserts the wire between the blades; a measuring unit which measures the displacement of the blades caused by the insertion of the wire; and a predication determining unit which determines the acceptability of the terminal by predicting the contact loads and the core wire based on the displacement and the reference data. The rotary members are twisted relative to the frame member and thereby biased relative to the plate-like terminal. Abstract: A welding terminal for electrically connecting a conductor portion of a wire includes a terminal base plate portion, on which the conductor portion is placed for welding and a pair of side walls, formed on opposite side edges of the terminal base plate portion so as to stand perpendicularly. The plate spring has an abutment portion formed by bending a plate member and is brought into abutment with both sides of the male connector terminal contact surface which is brought into contact with the plate spring. Abstract: A conductive portion of a wire, composed of a plurality of core wires, is inserted and fitted into a groove in a pressing die, thereby restricting the conductive portion to a bonding width of a terminal, and in this condition with the use of a press forming machine, the conductive portion is pressed in a thickness direction thereof to be formed into a flat shape. If in this connection state the motors 1 and 2 are driven or a vehicle is driven, vibration or impact is transferred to the motor cable device 5 from the motors 1 and 2 or the exterior, and thus the cable bodies 6 and 7 swing in an arrow direction. Abstract: A method of determining the acceptability of a press contact of a wire between press contact blades of a terminal.。 。
