Abstract
An electrical connector (1,1') having multiple contacts (40') are arranged in the insulating housing (10) at a predetermined pitch and have a J-shaped connecting section (44). When an external force (F), which tends to pull a flat cable (4) in a direction away from connector (1) is applied to the flat cable (4), connecting sections (44) of all contacts (40) are bent and their back surfaces (56) are pressed against the inner wall (30) of the insulating housing (10). This pressure generates resistance from the inner wall (30) resulting in a strong frictional force between connecting sections (44) and flat cable (4), thus reliably securing cable (4) in the connector housing.
Claims15
An electrical connector for electrical cables, comprising:
- a dielectric housing with an opening for receiving an electrical cable and slots formed therein for receiving electrical contacts;
- an electrical contact having portions thereof received in a pair of said slots, said slots being separated by a portion of said housing;
- said electrical contact portions comprising a resiliently deflectable connecting section and a stabilizing section which each project away from a base section of said electrical contact;
- whereby upon insertion of said electrical cable into said housing said resilient connecting section engages and deflects in a direction away from said electrical cable, and a force which tends to separate said cable from said housing causes an end portion of said resilient connecting section to engage the housing and the electrical cable at the same time thereby securing said electrical cable to said electrical contact and said housing, and the portion of said resilient connecting section between said end portion and said base section of said electrical contact is a generally straight contact section, the stabilizing section has a proximal end which joins the stabilizing section to the base of the contact, and a distal end opposite said proximal end, the stabilizing section being rigid between said ends.
An electrical connector for electrical cables, comprising:
- a dielectric housing with an opening for receiving an electrical cable, and slots formed therein for receiving electrical contacts;
- an electrical contact having portions thereof disposed in a pair of said slots, said slots being separated by a portion of said housing defining a partition, said partition defining first and second inner wall surfaces of said slots;
- said electrical contact portions comprising a resiliently deflectable connecting section disposed in a first slot, a stabilizing section disposed in a second slot, and a base section from which said connecting and stabilizing sections extend;
- whereby when said electrical cable is in an inserted position relative to said housing, a force which tends to separate said cable from said housing causes an end portion of said connecting section to engage the housing and the electrical cable at the same time thereby securing said electrical cable to said electrical contact and said housing, said stabilizing section comprises a longitudinal axis said partition walls being generally parallel thereto across generally their entire length.
An electrical connector for connection to a flexible flat cable, comprising:
- a dielectric housing having an opening to receive an end of the flexible flat cable and a plurality of slots perpendicular to the opening, each of the plurality of slots being separated by an isolation wall extending inwardly from one end of the housing at which the flexible flat cable is to be inserted thereby forming primary slots and secondary slots;
- a plurality of flat electrical contacts inserted in the slots in said housing from another end thereof, each of the electrical contacts has a base section positioned in the slots at the other end of said housing, a stabilizing section extending from the base section and disposed in the secondary slot, a J-shaped resilient connecting section extending from the base section and extending along the primary slot, said connecting section having a free end bent at an acute angle toward said isolation wall and the base section, and a soldering tail extending outwardly from said housing.
