A type of stamping die in which multiple terminals are produced in one stroke and are designed side-by-side and the raw material width is approximately equal to the extended width of the terminal.
See Surface Mount Automated Placement Equipment.
A foreign particle in the conductive layer, plating, or base material.
Part of crimping die set, it shapes the terminal barrel into the desired configuration while the nest provides the location and support for the crimping process.
See Reference Edge.
In fiber optics, materials placed between terminals of a connector to reduce coupling loss.
In fiber optics, a basic property of glass describing the velocity of light within the material. It establishes the numerical aperture for optical fibers and is used to calculate the time delays in high speed data links.
Voltage induced in a wire or coil as a result of a changing magnetic field.
See Inductance (Line).
The inductance of a transmission line, normalized to the unit length of the conductors for lines whose equivalent circuit is a distributed transmission line, and from the interaction of the external magnetic fields of two conductors (add to this result also the self-inductances due to the internal magnetic fields of the individual conductors for the (total) Inductance (Line) ) carrying current in opposite directions, i.e., a transmission line. Also a special case of Mutual Inductance. Its units of dimensions are: henrys per unit length. Symbolized by H.
See Mutual Indutance.
See Self-inductance.
The phenomenon of a voltage, magnetic field, or electrostatic charge being produced in an object by lines of force from the source of such fields.
Heating a conducting material by placing it in a rapidly changing magnetic field. The changing field induces electric currents in the material and 12R losses account for the resultant heat.
A method of soldering in which the solder is reflowed or supplied by preforms. If the work is moved slowly through the energy field, the induction process may be made continuous.
Crosstalk resulting from the action of the electromagnetic field of one conductor to the other.
See also Inductance.
Any coiled device, with or without a magnetic core, used to introduce inductive reactance into a circuit. An inductor is an energy storing device. Inductors oppose any change in current. Inductors are the mirror-image counterparts of capacitators (which resist voltage changes). Inductive reactance is defined as XL = 6.28 fL or XL = 2(pi)fL. Inductors block AC and pass DC.
A soldering process in which heat from infrared radiation is used to melt solder paste between connector leads and PCB pads to make a solder joint.
A material which prevents or delays oxidation and galvanic action on a connector surface or the interface of different conductors.
One of several conductive materials used for any of the following purposes:
Input Impedance
The impedance that exists between the input terminals of an amplifier or transmission line when the source is disconnected.
A mating pair of connectors used to carry signals into and out of a panel-mounted subsystem.
Difference between the currents of two input terminals of an operational amplifier when the output is at zero.
The voltage that must be applied between the two input terminals of an operational amplifier to obtain zero output voltage.
A mated pair of connectors used to carry signals into and out of a panel-mounted subsystem.
That part of a connector that holds the contacts in proper arrangement and electrically insulates them from each other and from the shell.
The number, spacing, and arrangement of contacts in a connector.
A defined hole in the connector insert into which the contacts are inserted.
The force required to mate a male and female connector.
Additional loss in a system when a device such as a connector is inserted, equal to the difference in signal level between the input and output.
A small hand-held tool used to insert contacts into a connector. Insertion tools are used to insert terminated cable into connector housings, especially where multi-stranded or soft cables are present.
Axial load in either direction which an insert must withstand without being dislocated from its normal position.
The maximum allowable force which, if applied to the mating face of a connector insert, does not displace the insert permanently from its normal position in the connector housing or jeopardize or damage the insert connector housing retention provision.
The wiring on the customer side of the FCC-defined network interface point in the United States.
A sensor device to inspect parts for defects and only allow good parts to pass through. Rejects are ejected out of the system. The extent of inspection depends on the device used. Some of the devices used are: fiber optic sensors, lasers, video-cameras, etc.
A hole placed at one end of a crimped terminal barrel that permits visual inspection to see that the conductor has been inserted to the proper-depth in the barrel prior to crimping.
Solderless terminal with an insulated sleeve over the barrel to prevent a short circuit in certain installations.
See Dielectric.
The degree of looseness or tightness of the insulation over the base conductor, measured in terms of force required to remove a specified length of insulation from the wire.

Insulation Displacement Technology (IDT)

The grip of a crimped terminal.
See also Crimp.
A termination technique in which a metal lance or tine in the terminal passes through the insulation and into the conductive strands. Insulation pierce is neither crimp or insulation displacement, but sometimes it is combined with these techniques. Also known as cable pierce or wire pierce.
A terminal designed for insulation piercing termination.
See also Insulation Pierce.
The molecule cavitation/separation pressure caused by a potential difference across an insulator. The practical electrical stress on insulation is expressed in volts per mil.
An extension of the rear portion of the contact, which gives the wire side support, but not longitudinal support. This section is not crimped, as is the insulation grip.
All of the insulation materials used to insulate a particular electrical or electronic product.
