GLOSSARY
INSERTION FORCE : It’s force resulting when the pin contact get engaged in the socket contact. It’s usually given in Newtons INSULATOR : It’s the plastic components located between contacts for multi-part contacts (COAX, TWINAX, QUADRAX). There could be multiple insulators per contacts. ELECTRICAL IMPEDANCE (or IMPEDANCE) : Electrical impedance, or simply “impedance,” describes a measure of opposition to alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. When the circuit is driven with direct current (DC), there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angle. VOLTAGE STANDARD WAVE RATIO (or VSWR) : It’s used to measure the efficiency of a transmission line. The value is expressed as a ratio with 1 (1:1, 2:1, 3:1). A perfect transmission line would be 1:1. CRIMPING TOOL : The crimping tool is the tool used to crimp the wire into the contact. It’s usually used with a additional component called positioner or die sets.
FREQUENCY RANGE : It’s define the better range of frequency in utilisation to obtain the better performance of the couple cable + contact.
INSERTION LOSS : It’s the difference between theamount of data has been sent versus the data received.
POSITIONER : This complementary component of crimping tool is used to guide, locate the crimping area of the contact during the crimping operation.
DIE SET : This complementary component of crimping tool defines the hexagonal crimping die.
