A filter insert (40) includes filters (43) having electrodes (48, 60) and contacts (54, 64) axially, mechanically engaging contact post members (28) of a connector (20) to provide filtering extending between signal and ground conductors in the form of connector contacts to filter unwanted signal frequencies. An alternative insert (68) includes filters (69) having slotted beam elements (78) that engage post members (28) from a side thereof with a common ground bus (90) tying the filters to ground. A further alternative insert (108) provides contact elements (116) connecting filters (103) to signal and ground conductors in the form of the wires (104) of a cable (102). The contact elements (54, 64, 78, 116) of the inserts (40, 68, 108) bite into the signal and ground conductors or contacts of a connector or a cable to provide a solderless interconnection of the insert. Filters, including dielectric elements (56, 86, 126,) and inductive elements (44) are contemplated to provide C, LC and pi-filters.

Filter insert for connectors and cable

A method and terminal for mass terminating conductors with high reliability combines insulation piercing and solder technology. Terminals are formed with insulation piercing, conductor engaging portions which have a layer of solder integral therewith. Respective conductors are terminated by the terminals in an insulation piercing operation and the solder reflowed to form a permanent bond therebetween. The terminal slot is designed to clean the conductor surface as well as to fixture it for the solder reflow operation.

Select solder slot termination method

A sealed insulation displacement connector comprises a first housing member in which is located an electrical terminal having a slotted insulation displacement section, and a second housing member in which an elastomeric body of sufficient rigidity is disposed so that when an insulated conductor is aligned with the slotted insulation displacement section the housing members are moved relative to each other causing the elastomeric body to forcefully move the insulated conductor into the slotted insulation displacement section thereby terminating the conductor with the elastomeric body sealingly engaging the connection formed between the conductor and the electrical terminal.

Sealed insulation displacement connector

A multiple terminal connector has structure which causes the profile of the multiple terminals contained therein to be altered thereby allowing low force insertion of the terminals into respective conductive holes of a multi-apertured device, such as a ceramic integrated circuit. The terminal connector comprises two pieces of insulative material forming a housing. The first housing portion has a plurality of terminals mounted therein and the second portion of the housing is moveable with respect to the first portion along the axial length of the terminals to modify the profiles thereof to facilitate their insertion into multiple plated holes of an integrated circuit board or the like.

Multi terminal low insertion force connector

A method is disclosed for forming a package for leadless integrated circuit substrates. Two identical webs of conductive material are formed into ladder like arrays of parallel terminals. One web has first housing portions formed on opposite ends of the terminals which are then formed on the housing portions. The second web is placed overlying the first web and between the first housing portions and second housing portions molded thereon integral with the first housing portions. The second terminals are then formed to finish the package.

An improved cable having low crosstalk characteristics is comprised of a pair of multi-conductor cable members laminated together with the pairs of wires of and between the respective cable members being so spaced as to effectively form a balanced capacitive bridge configuration. The conductors of the cable members can be either round or flat in section and the cable members are preferably secured together across their entire width by means which allows the cables to be readily separated at the termination. This capability for separation of the cable members is also effective for inserting a tap means intermediate the ends of the cable.

Multi-pair cable having low crosstalk

An improved electrical terminal is disclosed having a mating first end and a conductor engaging second end which is of the insulation piercing type including at least two tine members defining a conductor engaging slot therebetween. At least a portion of the conductor engaging end of the terminal is coated with a layer of insulation. As a terminal, which has the entire second end coated with insulation, is engaged with a conductor, the tines penetrate the conductor insulation and a portion of the insulation coating is stripped from the slot by the interference fit of the conductor in the slot to effect good mechanical and electrical interconnection therebetween. Also, only the tips of the tines can be coated to assure no electrical contact with any conductor they might engage. Thus the subject terminal may be used on shielded cable when it is desired to interconnect with the conductors but not with the shielding. In cases of cables having conductors on close center lines, where there might be concern about the occurrence of shorting between a terminal and an adjacent conductor, terminals having insulation coating their sides can be used.

Insulated contact

An improved cable having low crosstalk characteristics is comprised of a pair of multi-conductor cable members laminated together with the pairs of wires of and between the respective cable members being so spaced as to effectively form a balanced capacitivebridge configuration. The conductors of the cable members can be either round or flat in section and the cable members are preferably secured together across their entire width by means which allows the cables to be readily separated at the termination. This capability for separation of the cable members is also effective for inserting a tap means intermediate the ends of the cable.

A technique is described for completely and positively wiring components into mass produced machines, such as washing machines, dryers and the like. The subject technique encompasses improved contacts, connectors and a wiring harness all of which are individually and collectively adopted to provide a readily ascertainable positive visual indication of a full mating condition and which will prevent further assembly of components if not initially fully assembled in the proper relationship. Each subassembly of a connector and related component includes keying means allowing only correct assembly and mounting in the machine plus visual indicators which verify correct assembly at each step. The connectors preferably have housings which can be produced in great lengths and cut to the desired shorter lengths. These housings also include strain relief means for the associated conductors and may be hermaphroditic. Each contact terminal includes an insulation displacing conductor engaging portion, enabling rapid connection with associated conductors, and a matable portion adopted to readily engage several different size mating contacts. In the preferred embodiment, the contact terminal is also completely hermaphroditic both in the manner it mates with other contacts and with regard to which end makes an insulation displacing engagement with an associated conductor.
