A joint connector according to the present invention is provided with a circuit board, a male connector having male terminals provided on the circuit board at a predetermined interval and standing in one direction and a direction that crosses the one direction, the male terminals being selectively connected by a copper foil circuit, and a female connector in which female connector elements each having female terminals inserted and interlocked in female terminal holders are stacked, wherein the male connector and the female connector are fit to each other. This achieves cost reduction and improvement in work efficiency in electric wire connection by attaining easy electric wire connection and branching.

Joint connector

An electrical connection box is comprised of a wiring base group constituted by a minimum number of wiring bases required to realize a wiring pattern suitable to specifications of the connection box. Each wring base includes a base body, wing portions provided on an outer periphery of the base body having end faces each formed with a coupling portion to which another wiring base of the same construction can be coupled, and guide portions integral with the wing portions and projecting circumferentially therefrom. In receiving a wire fed from a wiring head in a desired wire groove of the wing portions via a corresponding wire guide groove of the guide portions, the guide portion concerned prevents the wire from being dislocated from the wire groove, resulting in increased wiring speed, shortened wiring time and reduced manufacturing costs.

An electric connecting apparatus provides electrical connection of two electric components by fitting a plurality of male terminals into mating female terminals. If the male terminals have different lengths, for example, the male terminals are fitted into the female terminals in an order of a longer one to a shorter one. In this case, the inserting force that is needed for the entire array of male terminals at the time the two electric components are connected together does not reach a peak at one time, but the inserting forces for the individual male terminals reach peaks one after another. This can permit the two electric components to be connected together with a less labor.

Electric connecting apparatus for electrically connecting two electric components

A method of manufacturing a wiring board comprising the steps of winding an electrical wire around a insulating plate having a number of electrical wire grooves for placing an electrical wire therein and a number of terminal grooves formed at positions corresponding to the electrical wire grooves in which the attached pressure connection terminal is connected to the electrical wire making use of the electrical wire grooves; cutting the electrical wire wound around the insulating plate at desired positions; and attaching the pressure connection terminal at a desired position in the number of terminal grooves, a wiring board, and an electrical connection box manufactured by accommodating the wiring box in a casing.

Wiring board manufacture method, wiring board, and electrical connection box

Disclosed are a method of manufacturing a wiring board, and an electric connection box manufactured by retaining the manufactured wiring board in a case. The method comprises the steps of winding electric wires around an insulating plate in first and second directions different from each other; cutting the electric wires at a first desired position; connecting the electric wires at a second desired position where the electric wires cross each other; and attaching a connecting terminal to the electric wires at a third desired position.

Method of manufacturing wiring board, and electric connection box

An electrical connection box has upper and lower casings capable of being combined with each other, a wiring board located between the casings and having a plurality of independent electric circuits, and an insulating plate located between the upper casing and the wiring board. The upper casing is formed with a connector housing to be fitted with an external connector, and external connecting terminals coupled to the electric circuits and electrically connecting the electric circuits and the external connector or an L-shaped rib formed on the wiring board and capable of preventing the external connector from being fitted in the connector housing projects into the connector housing.

Electrical connection box

An electric connection box includes a casing formed with an inspection window, and an electrical connecting component accommodated in the casing. An identification mark attached to an outer face of the electrical connecting component indicates a production facility employed for production of the connecting component. Even when a number of electrical connecting components of the same kind are manufactured with use of a plurality of production facilities, it is possible to determine the facility employed for the production of the electrical connecting component accommodated in each individual electric connection box from outside of the connection box by visually confirming the identification mark attached to the electrical connecting component through the inspection window.

Electric connection box

An electrical connection box has a first casing and a second casing combined together, with a busbar, an insulating plate, and an electrically insulating wiring board between the casings, and mounted with electrical components. The second casing is formed with an extension extending sideways at right angles to the thickness direction of the second casing, and a control unit is provided on the extension.

An electrical connection box comprises lower and upper casings capable of being combined with each other, an electrically insulating wiring board located between the casings and having a wire laid in a desired shape thereon, a busbar in contact with at least a part of a wire laying surface of the wiring board, and an insulating plate located between the lower casing and the wiring board and/or between the upper casing and the wiring board. The insulating plate has thereon a projection for pressing the laid wire away from the busbar. The wiring board is formed with a laying groove in which the wire is laid. Post-formed protuberances for preventing the wire from getting out of the laying groove are formed in predetermined portions of the laying groove.

An electrical connection container suitable for mounting in a vehicle etc., provided with a plurality of press-fit terminals provided with engagement projections bent in directions perpendicular to the plane including press-fitting portions, whereby the pitch between the terminal portions may be reduced while securing an insulating distance and therefore the electrical connection container can be made smaller. Wire pressing ribs are provided projecting out from the bottom surface of a subplate so as to press the wires and press-fit them in the press-fitting portions of the press-fitting portions, at which time the wire pressing ribs push the wires riding above the spaces between protective walls into the space between the protective walls and thereby ensure stability of the electrical connection while keeping the wires substantially straight. Further, wires press-fit to the wire press-fit portions of the press-fit terminals are cut for each of the circuits and then laid.
