摘要： An electrical connector includes contacts to be connected to lead wires and a housing having apertures for receiving the contacts. The lead wires are connected to the contacts when the contacts are forced into the apertures of the housing. Each of the contacts comprises at one end a contact element to be in contact with an external terminal and at the other end a connection portion formed with a lead aperture through which a lead wire passes and with a slit continuous with the lead aperture. Edges of the slit pierce into an insulating coating of the lead wire and connect with a core of the lead wire under pressure. The housing is formed with through-apertures through each of which the contact element of each of the contacts extends and with receiving apertures each for receiving the lead wire under a condition that the edges of the slit of the connection portion of the contact pierce into the insulating coating of the lead wire and connect with the core of the lead wire under pressure and a remaining insulating coating is doubled. A doubled end of the lead wire received in each of the receiving apertures is positioned by a shoulder formed by a boundary wall between the receiving aperture and the through-aperture.

摘要： A connector for memory cards includes a connector housing having an opening for receiving the memory card and at least one contact which contacts a connecting portion of the memory card inserted in the opening to connect the card to a computer circuit. According to the invention, the contact is arranged so as not to be in contact with the connecting portion of the memory card and there is provided a contact operating plate slidably movable in the connector housing to bring the contact into contact with the connecting portion of the memory card when the contact operating plate has moved toward said contact. The housing further comprises an operating lever pivotally connected thereto and having one end inserted into an aperture formed in the contact operating plate such that upon pivotally moving the operating lever, the contact operating plate is slidably moved in the housing. The operating lever is formed with a card restraining body angularly extending therefrom so as to suppress one end of the memory card inserted into the housing, thereby preventing inadvertent removal of the memory card. The housing is further provided at the opening with a closing plate pivotally connected thereto and spring means permitting the closing plate to bring into an opening position by the memory card being inserted into the opening but urging the closing plate into a closing position upon removal of the memory card from the opening, thereby preventing foreign material from entering the opening.

摘要： A contact for a connector, which includes two opposed contact elements for receiving therebetween a male contact of a mating connector. Each the contact element is provided with one or more protrusions on an opposed surface for embracing the male contact. Protrusions of the two opposed contact elements extend to that portions of the opposed contact elements which are devoid of the protrusions so as to overlap each other before the male contact is inserted between the contact elements. With this arrangement, even if the male contact is very thin, pressing force required to securely pressing the male contact by the contact elements is certainly obtained. The contact and the male contact are securely contacted without any torsional force and other forces which would otherwise be caused on these contacts.
