摘要:
An electrical connector assembly (20) for a card reader including a housing (24) having opposed major and minor sides (26, 30) defining a card receiving mouth (32), a plurality of conductive electrical terminals (36) disposed in the housing (24) and having portions (38) thereof extending into the mouth (32), and a conductive shroud (50) encircling the housing (24), the shroud (24) having inwardly spaced contact portions extending into the mouth (32) along at least one of the major sides (26) of the housing (24), the shroud contact portions being spaced from the electrical terminal portions (38) when the shroud (50) is assembled to the housing (24). The inwardly spaced contact portions can be spring fingers (54) extending into the mouth (32) from an edge (53) of the shroud (50) or dimples (254) expressed into the mouth from an outer surface of the shroud (250). At least one of the major sides (26) of the housing (24) includes a plurality of shroud contact receiving recesses (28) adapted to receive the shroud contact portions such that the shroud contact portions are closely adjacent a card receiving space (34) thereby being positioned to be either electrically engaged by corresponding raised conductive surfaces (84) on an outwardly facing conductive surface (82) of a shielded card (70) upon insertion of the shielded card into the mouth (32), or to remain spaced from surfaces of an unshielded card (170) upon inserting the unshielded card into the mouth (32).
摘要:
An electrical connector comprises a dielectric housing having a terminal receiving cavity and an aperture extending into the housing at an angle with respect to the cavity and open to the cavity. A terminal which is insertable into the cavity has a component mounting surface which is arranged to be aligned with the aperture when the terminal is disposed in the cavity. The terminal and the cavity are configured with cooperating surfaces which guide the terminal during insertion into the cavity such that the component mounting surface does not contact the housing during the insertion, whereby contamination of the component mounting surface is prevented. A method for manufacturing an electromagnetic shielding device suitable for air flow vents of electronic instruments comprises forming a honeycomb and applying a conductive coating thereto.

An electrical connector (1) comprises, a cable receiving face on an insulating housing (2), a cable engaging face on a termination cover (3), cavities (6) in the housing (2), each of the cavities (6) communicating with two slotted openings (12), electrical contacts (13) received in one or the other of the slotted openings (12), insulation displacement terminals (15) on adjacent contacts (13) being wider than spacing between the adjacent contacts (13), and opposite sides of the terminals (15) being confined between respective first and second walls (9, 10) to resist bending of the terminals (15).
摘要:
Es wird ein elektrisches Kontaktelement angegeben, dass zur Befestigung und Kontaktierung mit metallisierten Bohrungen, beispielsweise einer Leiterplatte geeignet ist. Das Kontaktelement (1) weist einen Einpressbreich (2) und einen Anschlussbereich (4), der sich über einen Übergangsbereich (3) an den Einpressbereich (2) anschliesst, auf. Der Einpressbereich (2) besteht aus zwei Lagen (5,6) eines Metallbleches. Die Lagen (5,6) sind symmetrisch zu einer Ebene zwischen den Lagen aufeinander angeordnet. Jede der Lagen (5,6) weist ein zwischen zwei Kontaktschenkeln (9,10) ausgebildetes Langloch (7) auf. Die Lagen (5,6) sind zumindest im Bereich des Langloches mit den äusseren Rändern (109 bis 112) der Kontaktschenkel (9 bis 12) voneinander weg gewölbt.
摘要:
A socket (6) for an electronic package (2) comprises a dielectric housing (10) having contacts (20) each with a surface mount section (50) extending below a bottom surface (14) of the housing for engagement with a respective circuit trace on a circuit board. The surface mount section (50) of each contact has a convex bottom surface (52) with a shape which simulates at least a lower surface portion of a solder ball, whereby the socket imitates the footprint of a ball grid array package.
摘要:
A device (20) for coupling first and second electrical connectors (40, 70) comprises a dielectric member having a plurality of openings (32) extending therethrough, a first portion (34) of the openings (32) being adapted to grip corresponding exposed body portions (68) of terminals (60) secured in a first connector (40), and a second portion (36) of the openings (32) being adapted to grip corresponding exposed body portions (98) of terminals (90) secured in a second connector (70). Upon placing the first and second connectors (40, 70) adjacent each other and positioning the openings (32) in gripping relationship with respective body portions (68, 98) of the terminals (60, 90) of the first and second connectors (40, 60), the device (20) mechanically secures together the first and second connectors (40, 70) adjacent each other.
摘要:
An electrical connector housing assembly (2) having complementary connector halves (4, 6) where one of the halves (6) includes a locking device (36) characterized in that the secondary lock (36) is carrying an integral seal (46, 48) for forming a sealed interconnection between mating terminals (86) therein. The connector housings (6) may also include latches (54) that cooperate with a catch (68) to assure a first position where terminals may be inserted and a second position where the terminals may not be removed are positively maintained.

摘要:
A plug or switchboard insert has an insulating body which contains a plurality of parallel contact pins or sockets and which can be inserted into a plug housing or switchboard panel. The contact pins or sockets are accessible on the front side of the insulating body and can thus be plugged and connecting means are arranged on the rear side of the insulating body for connecting with a cable or cord. A strain-relieving bow for the cables or cords extends on the rear side of the insulating body, transversely to the axis of the contact pins or sockets. The strain-relieving bow has a plurality of bores for mounting clips or binders for clamping the cables or cords. The bow has at least one rod at least partially coated with a conducting material and provided with the bores for mounting the clips or binders and two legs made of a non-conducting material for securing the clips or binders directly to the insulating body.
