A method and assembly for electrically and mechanically connecting one or more flexible conductive members (11), with one or more insulated wires (12) using one or more insulation piercing terminals (13). The flexible conductive member (11) may have one or more electrically conductive layers (14) attached to a pliable backing (15). The insulated wire (12) may have one or more conductors (16). The insulation piercing terminal (13) provides a low impedance electrical connection between the flexible conductive member (11) and the insulated wire (12), while also providing a mechanical connection between the flexible conductive member (11) and the insulated wire (12) which minimizes movement of the insulated wire (12) due to any axial and/or longitudinal forces that may be applied to the insulated wire (12) or the flexible member (11) during manufacturing and use. The insulation piercing terminal (13) combines one or more piercing members (17) with an integral mechanical securing means and an electrical contact for engaging the flexible conductive member (11). The insulation piercing terminals (13), used in this method and assembly, eliminate the need to prepare either the flexible conductive member (11) or the insulated wire (12) prior to assembly. The method and assembly are of particular advantage to medical equipment manufacturers involved in designing and manufacturing flexible electrode type circuits, such as the return electrodes for use with electrosurgical generators or other electrodes or sensors associated with patient monitoring procedures and devices.

Method and assembly of member and terminal

In an electronic apparatus having a first and a second casing part, when the casing parts are rotated relative to each other about a hinge structure, a first and a second sleeve constituting a connector are also rotated relative to each other. A flexible conductive member is received in the sleeves so as to set up electrical connection between circuit portions built in the casing parts. The connector is removable from the circuit portions of the casing parts. Upon assembly, the electrical connection is set up only if the connector is connected to the circuit portions.

Flat flexible cable includes at least one conductor with an insulating film disposed thereabout. The cable further includes an opening through the film not in contact with the conductor. A connector for use with the flat flexible cable, includes an opening and a means for retaining the cable within the opening. The opening receives the cable such that one end of the cable is within the connector. The means for releasably retaining the cable within the opening is disposed through the opening in the cable, so that any force on the cable is transferred to the connector.

A temperature-dependent switch has a temperature-dependent switching mechanism, a housing accommodating the switching mechanism, two first connections between which first connections the switching mechanism makes or interrupts an electrically conductive connection depending on the temperature of said switching mechanism, and a heating resistor that is arranged on an outside of the housing and is connected electrically in series with the two connections. The heating resistor is a sheet-like metal part that is welded to the housing and carries a further connection.

A backshell housing and connector assembly are provided with strain relief in which the housing has a top and bottom shell with front and rear sections. Ledges with horizontal grooves disposed therein are located at the front sections of both shells. Piercing means are also provided on at least one ledge that pierces the web of jacket insulation when the housing is assembled. Energy directors are also provided that capture ultrasonic energy and cause welding of the two shells.

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.

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.

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.
