With Stress Relieving Means For Conductor To Terminal Joint Patents (Class 439/399)
  • Publication number: 20020001994
    Abstract: A terminal fitting (T) has a pair of crimping pieces (17A, 17B) that extend up from opposite side edges of a bottom wall (11), and are crimped into connection with a wire (W) placed on the bottom wall (11). The crimping pieces (17A, 17B) are offset to each other in the longitudinal direction of the wire (W). Restricting portions (18A, 18B) are formed on the bottom wall (11) and restrict a lateral displacement of the wire (W) against pushing forces acting on the wire (W) from the crimping pieces (17A, 17B) in directions normal to the longitudinal direction of the wire (W) while the crimping pieces (17A, 17B) are being crimped into connection with the wire (W).

  • Patent number: 6296512
    Abstract: A press-connecting terminal (1) includes a plurality of press-connecting blades (9, 10). A gap between the pair of press-connecting blades (9) is smaller than the diameter of the electric wire (7), and a gap between the pair of press-connecting blades (10) is smaller than a diameter of a conductor (7b) of the electric wire (7). When the electric wire (7) is press-fitted relative to the press-connecting blades (9, 10), an end portion of the electric wire (7) is held by the pair of press-connecting blades (9) while the conductor (7b) is press-connected to the pairs of press-connecting blades (10) in electrically-contacted relation thereof. In so far as a variation in diameter of the electric wire (7) is within a predetermined range, the good press-connecting operation is effected, and the press-connecting terminal (1) has enhanced versatility.

  • Patent number: 6155865
    Abstract: An insulation displacement contact terminal has a pair of side walls, an a pair of pressure contact blades that are mutually opposing and formed by partial bending away from the side walls. When an insulated wire is inserted between the pressure contact blades along a first direction, edges of the pressure contact blades bite into the insulation of the insulated wire so as to make contact with the inner core wire of the insulated wire. The pressure contact blades each have a curved part that is continuous from the side walls, and each curved part has a radius of curvature such that when the pressure contact blades are bent from the side walls and when a pulling force is applied to the insulated wire in a second direction that intersects with the first direction, concentration of bending stress acting on the pressure contact blades is relieved.

  • Patent number: 4834670
    Abstract: An insulation displacement terminal assembly comprises an insulation displacement terminal having a U-shaped insulation displacement portion which has two plate sections that are connected by a bight and insulation displacement slots that extend through the bight and down into the plate sections in aligned pairs of insulation piercing slot portions. A plurality of insulated electric cables are disposed in the insulation piercing slot portions and retained therein to form a sub-assembly. The sub-assembly is assembled into a slide-in insulator housing portion which has slots in its opposed side walls through which the insulated electric cables of the sub-assembly extend and a retention tongue that is cantilevered from a back wall of the housing portion and runs parallel to the slotted side walls to project between the insulated electric cables and the bight of the insulation displacement terminal to retain the electric cables down in the insulation displacement slot portions.

  • Patent number: 4822297
    Abstract: A junction block for tap-in connection to a continuous two-conductor line comprises a removably mutually engageable base and a cover, defining axially aligned wire entrance and exit apertures, and a passage admitting a plug. Conductor positioners each define a conductor path between the apertures; insulation displacement means are positioned for cooperative interaction with the positioners. Each displacement means is electrically connected with a contact spring adjacent the passage.A positioner and its cooperating displacement means together define a conductor engagement position generally on a level with the wire apertures, so that tension on the wire external to the block does not tend to pull the conductors out of the displacement means. The block has cooperating alignment means mutually engageable during assembly positively to align the positioners with the displacement means before the conductor insulation is engaged, and to prevent misassembly of the block components.

  • Patent number: 4806120
    Abstract: The connector has a body part (4) of good electrical conductivity and which is of U-shaped cross section. A pair of wings (18) extend from one or both ends of the side walls (16) of the body part (4) and define a wire slot (20). The wings (18) are not connected to the base (12) of the body part (4), so as to allow the side walls (16) of the body part (4) to be deflected away from each other. A U-section spring (10) receiving the part (4), and being separated therefrom, resiliently restrains deflection of the side walls (16) of the body part (4) away from each other, when a wire (W) is inserted into the wire slot or wire slots (20). The spring part (10) stores energy so as to maintain the integrity of the electrical connection between the edges of the slot or slots (20) and the core (C) of the wire (W), despite temperature cycling. The spring characteristics of the spring part (10) can be selected to achieve a desired contact force.

  • Patent number: 4734054
    Abstract: The contact elements of the plug connector are engaged into chambers of an insulating strip by means of a conductor terminal component which has cutting and clamping contact edges. The chambers are only open towards a flat side of the strip, so that a conductor can be pressed into the contacting slots of the cutting and clamping contact points from the open side of the chambers. This allows an uncomplicated, orderly connection of the conductor to the contact elements after the connection of the contact elements to the insulating strips. A plurality of such strips can then be inserted into a housing and combined with the latter to form a multi-row, e.g. three or four row, plug connector.
