Abstract: Microelectronic contacts, such as flexible, tab-like, cantilever contacts, are provided with asperities disposed in a regular pattern. Each asperity has a sharp feature at its tip remote from the surface of the contact. As mating microelectronic elements are engaged with the contacts, a wiping action causes the sharp features of the asperities to scrape the mating element, so as to provide effective electrical interconnection and, optionally, effective metallurgical bonding between the contact and the mating element upon activation of a bonding material.

Abstract: An electrical connector housing element includes passages each receiving an electrical contact and a system for locking them. The passages are in two series each comprising two rows. The locking system includes two keys in a head-to-tail arrangement and each of which is U-shape with two branches and a core. Each key is mounted so that one of its branches lies between the branches of the other key. Inclined guides are provided in a groove whereby each key can move in the groove in two perpendicular directions. In a locking position the two branches of the first key immobilize the electrical contacts of the two first rows of the two series of passages. In the locking position the two branches of the second key immobilize the electrical contacts of the two second rows of the two series of passages.

Abstract: An electrical plug-type connector has primary securing means formed by an interlock mechanism comprising a primary catch edge and a stationary contact wall of the housing that interact with the first catch tongue of the contact element. The opposite, second contact chamber wall is provided on a slide member that is movable at least transversely relative to the plug-in direction, but preferably also obliquely relative thereto and has a segmented catch edge having paths for the second catch tongue to pass therealong. By moving the slide, a primary and secondary secured interlock position of both catch tongues occur as a result of engagement behind the respective catch edges. This movement will also cause a forward feed of the contact element not correctly plugged in and primarily latched.

Abstract: An electrical terminal comprises an inner contact body and an outer spring body. The outer spring body is box-shaped and encloses the inner contact body. The outer spring body comprises spring beams edge-stamped out of top and bottom walls respectively. Protrusions are positioned centrally along the spring beams, and project beyond side walls of the outer spring body such that when the terminal is inserted into a corresponding housing cavity, the protrusions interfere with walls thereof. The spring beams are thus resiliently biased and the terminal is resiliently held within the housing cavity such that chattering of the terminal therein is prevented. Vibration movements parallel to the top and bottom walls causes the spring beams to act in the plane of the metal, and vibration movements perpendicular thereto cause the spring beams to act in torsion. Due to the edge-stamping of the spring beams out of top and bottom walls, they are very simple to manufacture, yet very effective, robust and reliable.
