The design feature that fills the voids between the faces of plug and receptacle when they are fully engaged. This feature provides an environmental seal between the faces of the plug and receptacle and also increases the dielectric between contacts, that can increase the service rating of the connector.
FAR END CROSSTALK RATIO (FEXT)
The crosstalk ratio calculated on the quiet line at or in proximity to the receiving (destination) end of the driven line. This is the ratio of the far end quiet line signal amplitude to the near end driven line signal amplitude.
A connector, terminal block, or terminal device having conductive elements accessible from opposite sides of an insulator, or a partition for termination or connection with mating devices.
A concentric or triaxial contact where the outer contact is female and the center contact(s) may be male or female.
A contact intended to make electrical engagement on its inner surface and that will accept entry of a male contact.
(1) A short tube used in the rear of a crimp contact to reduce its diameter, to allow the use smaller wire in the contact cavity. (2) A sleeve or tube used in coaxial connectors and contacts for the termination of the shield(s). (3) A sleeve of tube in some fiber optic connectors for the termination of the strength members.
FIBER OPTIC CABLE
A single or group of optical fibers enclosed by a common protective jacket and usually including a strength member.
A material used to fill the voids in a cable. A filler can be used to maintain the shape of the cable, to maintain the watertight integrity of the cable, or to protect the internal components of the cable (e.g., wires or fibers).
A contact with an integrated filter element included to discriminate against certain frequencies.
A connector capable of withstanding flame of a specified temperature for a specified time.
The first conductive element to make physical electrical contact when two connector halves or a socket and an electrical component are physically mated together.
A connector for attachment to a rigid surface.
A contact that is permanently included in the insert material during molding.
(1) A tongue extending from the side of a hermetic contact onto that a wire is soldered. (2) A rectangular tab used in some lug type applications.
A terminal having a tongue or body projecting at 90 degrees from the side of the terminal barrel.
A projection extending from or around the periphery of a connector for the purpose of attaching the connector to a rigid surface or mating connector.
FLANGED SPADE TONGUE TERMINAL
A slotted tongue terminal having the ends of the tongue formed up or down to the tongue plane, so as to form a degree of protection against the terminal slipping out from under its captive hardware.
A thin film of material formed at the sides of a forging, casting, or molded part where some of the material is forced out between the faces of the forging dies of the mold halves. Also the excess metal extruded between both halves of crimping dies when making certain circumferential or symmetrical crimps. Also, would include a thin deposit of plastic material usually at the base of molded-in pins.
The application of extremely thin deposits of a plating material for environmental protection or as a base for a subsequent layer of plating material.
Any cable with two smooth or corrugated but essentially flat surfaces.
FLAT CABLE CONNECTOR
A cable designed specifically to terminate flat cable. May be designed for flat conductor flat cable, or round conductor flat cable.
Damage usually occurring where a cable enters the housing, that is caused by the sharp bending of the cable. A flex relief restricts the concentration of flexing forcing the cable to bend over a wider arc.
FLEXIBLE PRINTED WIRING
A random arrangement of printed wiring utilizing flexible base material with or without flexible cover layers.
The strength of a material in bending expressed as the tensile stress of the outermost fibers of a bent test sample at the instant of failure.
A fixed connector with mounting means permitting limited movement to facilitate alignment with the mating connector.
A design feature that aids in the alignment of plug and receptacle shells during engagement. The floating bushing generally is an eyelet type bushing that is fitted into the plug mounting holes so that there is freedom of movement in all directions between the plug and receptacle.
A sleeve used to compress the grommet, thus tightening the seal around the wire entering the connector.
FORCE, CONTACT ENGAGING
The force required to fully engage a pair of contacts.
FORCE, CONTACT RETENTION
The minimum allowable force that, if applied axially in either direction on a contact, does not displace the contact permanently from its normal position in the connector or jeopardize or damage the contact retention provision.
FORCE, CONTACT SEPARATION
The force required to separate a pair of fully mated contacts.
FORCE, INSERTION RETENTION
The minimum allowable force that, 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 or connector housing retention provision.
In the case of a multiple contact connector having a removable body or insert, the frame is the surrounding portion (usually metal) that supports the insert and permits a method for mounting the connector to a panel or mating connector half.
A connector for attachment to the free end of a wire or cable.
FREE COUPLER CONNECTOR
A connector that mates with a free connector in a cable-to-cable application.
FRESNEL REFLECTIONS LOSSES
Losses incurred at the terminus interface due to refractive index differences.
A condition where slight movement between mated surfaces occurs, continually exposing fresh metal. As the freshly exposed metal oxidizes, the oxidation builds up until electrical continuity is broken.
A connector mounted with its mounting flange positioned in front of the mounting surface when looking at the mating face or front side of the connector.
FRONT RELEASE CONTACTS
Connector contacts that are released with a tool from the front side of the connector and then removed from the back (wiring side) of the connector. The removal tool engages the front portion of the contact and pushes it out the back where it is removed by hand.
FULL CYCLE CONTROL
Controls placed on the crimping cycle of crimping tools forcing the tool to be closed to its fullest extent, forcing completion of the crimping cycle before the tool can be opened.
Flared or widened entrance to a terminal or connector wire barrel that offers easier conductor insertion, and assurance that all wire strands are directed into the wire barrel.
