Thermoplastic vinyl insulated building wire, 60° C.
A branch connector that joins a branch conductor to the main conductor at a 90° angle.
Dimension of the crimped portion of a connector, measured between two opposite points on the crimped surface. Also called G dimension.
A Premium line 2.0 mm pitch wire-to-board single row crimp connector system originally introduced for the audio/video industry.
Switchboard wire insulated with thermoplastic and felted asbestos, 90° C.
Flexible nickel or nickel-clad copper, PTFE tape, felted asbestos, asbestos braid, 200° C.
A membrane switch that makes a snap when depressed.
The length of the header or pin, as dictated by the thickness and spacing of the PCB to which it will be attached.
See Locking Spring.
Method of joining insulated or non-insulated low resistance wires.
A form of multiple conductor consisting of parallel metal strips im7bedded in insulation material. Also called flat flexible cable.
A method of handling and transporting loose components by supporting them with a continuous strip of tape and rolling this strip onto a reel. This technique is controlled by EIA standard RS 481.
Terminal supplied in a continuous form for use in automatic or semiautomatic crimping machines. Also called strip terminal.
A flat terminal that has tapered sides designed to receive a mating tapered female terminal.
Three cotton braids, weatherproof saturated.
Switchboard wire, thermoplastic insulation, flameproof cotton braid, 600 in. 90° C.
Tinned Copper
Time Domain Reflectometer. A test instrument which can electrically characterize a transmission line discontinuity (its specific characteristic impedence and electrical length) through use of a radar-like signal and the analysis of the signals reflection.
In fiber optics A test to determine the tear strength of an insulating material.
In fiber optics, an optical component used to interconnect a number of terminals through optical wave guides by using partial reflections at dielectric interfaces or metallic surfaces, or by splitting the optical wave guide bundle.
Transverse Electromagnetic. The preferred mode of electromagnetic signal wave propagation down a transmission line, allowing both monomode propagation and simplified transmission line characteristics and behavior.
The TEM mode has no electromagnetic field variations in the z-axis or transmission line axial direction, only in the perpendicular cross-section directions.
The TEM mode also requires for its existence a skin effect condition to exist for the conductors of the line as well as a homogeneous dielectric medium.
See also Skin Effect.
Temperature change of a terminal from a no load condition to full current load. Also called T Rise.
For crimp technology, the amount of axial load required to break or pull wire from the crimped barrel of a terminal, splice, or contact.
Greatest longitudinal stress that a substance can bear without pulling apart.
A somewhat confusing term because it is used differently in the telecommunications and data communications industries.
In the telecom industry:
In the datacomm industry:
In the connector industry:
Non-preferred term for land.
An assembly that contain connection provisions to facilitate the connection of one or more conductors.
Board fabricated from an insulating material that contains a single or multiple row or arrangement of termination points, for the purpose of making connections.
A connector that joins a conductor to a lead, terminal pad (solid or laminated block), or round terminal stud of an electrical apparatus.
A housing that fits over switch terminals to protect against electrical shock and accidental shorting, and to facilitate wiring.
A hole used for the attachment and electrical connection of component terminations, including pins and wires, to the PCB.
A terminal designed to be affixed, usually at one end, to a post, stud, chassis or the like, and with provision for attachment of a wire(s) or similar electrical conductor(s) in order to establish an electrical connection.
See Land.
A conductive busing or commoning bar.
An insulated mounting for terminal connections. Terminal strips are available with threaded holes to accept threaded screws or with threaded studs to accept fastening washers and nuts. If terminal areas are separated by an insulating barrier, the terminal strips are called barrier blocks.
Refers to the tongue design of the terminal.
See Terminal Block.
Tool or kit for tools used to terminate wire to connectors. developed to service the automotive and computer markets in the Far East.
In fiber optics, an item that terminates an optical conductor and provides for the location and containment of an optical conductor within a connector.
A flexible, insulated lead wire that usually has a test prod on one end. It is ordinarily used for making tests, connecting instruments to a circuit temporarily, or for making temporary electrical connections.
Special points of access to an electrical circuit, used for testing purposes.
A miniaturized block for small instrument and test circuitry. It has test points plus an informal circuit testing facility of either a plug or knife-blade disconnecting mechanism.
