A cord reel mechanism which includes a housing having inner and outer cylinders. A tape-like cord is vortically wound about the inner cylinder inside the housing. The inner and outer cylinder rotate relatively so as to tighten and loosen the cord. Reinforcing tape segments are attached to the tape-like cord at spaced locations to support the cord and prevent buckling. The reinforcing tape segments each have a tapered portion and an attachment portion.

Cord reel mechanism

A flat-type electric wire is spot-welded to a connector terminal while the connector terminal is pressed by a pressing plate with a predetermined pressing force, so that stable spot-welding is always performed.

Method of stabilizing spot-welding

A molded circuit component for connecting to lead wires includes body and a protective cover. The body includes a partition wall area having a plurality of housing grooves, partition walls, body notches, positioning projections and fastening pin reception apertures. The protective cover includes a plurality of cover notches, recesses and fastening pins to correspond respectively with the body notches, positioning projections and fastening pin reception apertures. Metal lines having connection terminals on their ends are embedded in the housing grooves. Lead wires are positioned in the grooves so that the conductors of the lead wires are placed on, and attached to, the connection terminals. The protective cover is then attached to the body.

Molded circuit component unit for connecting lead wires

A molded electrical connector for connecting electrical conductors comprises a molding section in which a plurality of metallic circuits are arranged in parallel with one another at predetermined intervals and are fixedly molded with resin such that first end portions of the metallic circiuts are exposed as connecting terminals. The molded electrical connector further comprises a connecting section which comprises the connecting terminals. The connecting section is molded with resin simultaneously when the molding section is formed. Electrical conductors are placed on the connecting terminals of the metallic circuits and welded together.

Moulded electrical connector and method for manufacturing same

An apparatus for joining a plurality of lead wires with a corresponding plurality of flat type electric wires. The apparatus comprises a plurality of connector terminals, each having a first caulking portion for securing the round wire to a first end of the connector terminal, and a clasping portion for securing the flat wire to a second end of the connector terminal, the clasping portion comprising a first and second spring portion, a projecting portion projecting from the clasping portion toward the flat wire, and second caulking portion for compressing the flat electric wire between the first and second spring portion by securing the first spring portion to the second spring portion. The projecting portion may receive solder so that the flat type electric wire can be spot welded to the connector terminal. To prevent short circuits between the connector terminals, a comb-like spacer may separate the connector terminals, or the exterior of each connector terminal may be insulated. The connector terminals may be encased in resin or the like to provide further protection from exposure. The resulting connection is extremely compact, reliable, and provides a stable electrical connection over time.

Apparatus for connecting sets of electric wires to lead wires

A connector terminal for joining a round type electric wire with a flat type electric wire. The connector terminal comprises a first crimpable portion for securing the round wire to a first end of the connector terminal, and a clasping portion for securing the flat wire to a second end of the connector terminal, the clasping portion comprising a first and second spring portion, a projecting portion projecting from the clasping portion toward the flat wire, and second crimpable portion for compressing the flat electric wire between the first and second spring portion by securing the first spring portion to the second spring portion. The projecting portion may receive solder so that the first type electric wire can be spot welded to the connector terminal. The resulting connection is extremely compact, reliable, and provides a stable electrical connection over time.

Connector terminal

An antenna device for a system which includes cordless apparatuses, e.g. home automation system. Conductive patterns or conductive wires are provided on a conduit, which may comprise a round or a flat composite cable, for radiating signals to and receiving signals.
