Technical Field
The present invention relates to terminal assemblies, and more particularly, to a conductive terminal and a connector assembly thereof.
Background
A typical electrical connector includes a housing that houses one or more terminals. The housing may be made of an insulating material such as molded plastic or the like and the terminal may be made of a conductive material such as stamped and formed sheet metal. The housing includes a plurality of terminal slots into which the terminals fit. The terminals may be inserted into their respective terminal slots individually, or multiple terminals may be inserted "ganged" into multiple terminal slots simultaneously. The housing and terminals may be used to mate with a complementary mating connector or other connecting device, and the terminals may be terminated to circuitry on various conductors, such as wires, printed circuit boards, and the like.
Various problems continue to arise in the manufacture of the electrical connectors described above. Certain problems are particularly acute on high density connectors, i.e., when the terminals are very closely spaced. For example, in such high density connectors, closely spaced terminals present signal interference problems in the connector when the terminals are inserted into closely spaced terminal slots within the connector housing. Also, it is difficult to insert the high-density terminals into the housing in groups, and it is necessary to insert the terminals individually, which takes a lot of time. Further, it is difficult to determine when the terminals are fully inserted, particularly when the terminals are inserted into terminal slots in the housing.
