Definitions

  • the metal contact assembly of a clip connector terminal includes a wire yoke having leg portions and a contact element disposed in the plane of the yoke, flanked by said leg portions and forming a unitary structure with said yoke.
  • Each side of the contact element and each leg portion is provided with a sharp edge; a sharp edge of the contact element and a sharp edge of the yoke leg cooperate to cut through the insulation of an inserted conductor on diametrically opposed sides thereof and to maintain a continuous electric contact with said conductor.
  • This invention relates to a clip connector terminal for at least one insulated conductor and is of the type which is provided with two slots defined externally by the legs of a resilient wire yoke and internally by the sides of a contact element formed as a sharp contact knife. The end portions of the legs of the wire yoke and a part of the contact element are anchored in an insulating body or similar carrier.
  • the reliability of contact in this and other clip connectors is determined largely by three factors: a secure cut through the insulation of the conductor, a small contact resistance between the parts of the connector and a continuous contact pressure exerted by the connector on the conductor.
  • the leg portions of the resilient wire yokes too are formed as sharp contact knives along the locations of possible contact with the conductor and further, the wire yoke forms, with the contact element, an integral mechanical and electrical unit.
  • the insulation of the conductor attached to the clip connector is cut through securely by both the contact element and the wire yoke, ensuring a continuous good contact pressure on the conductor and further, the contact resistances between the conductor and the clip connector as well as between the contact element and the resilient wire yoke in the carrier body are maintained at all times at a very small value.
  • FIG. 1 is a perspective view of a first embodiment of the invention
  • FIG. 2 is a perspective view of a second embodiment of the invention.
  • FIG. 3 is a front elevational view of a third embodiment of the invention.
  • FIG. 3a is a side elevational view of the same embodiment
  • FIG. 4 is a front elevational view of a further embodiment of the invention.
  • FIG. 4a is a side elevational view of the same embodiment
  • FIG. 5 is a front elevational view of still another embodiment of the invention.
  • FIG. 6 is a perspective view of the embodiment of FIG. 1 with a modification
  • FIG. 7 is a perspective view of an embodiment according to FIG. 2 with a modification.
  • the clip connector shown therein is formed essentially of an inner leaf-like contact element la and a contact yoke 1b surrounding the contact element la.
  • the contact element la and the contact yoke lb form a structurally integral, unitary contact assembly 1 anchored in an insulating carrier 2.
  • the contact element 11a is of rectangular crosssection and'is formed at the linear flanks la and 1a", at the end which emerges from the insulating carrier 2, as a sharp-edged contact knife.
  • the contact element la merges, in the range of the insulating carrier, into a resilient rectangular contact yoke lb which surrounds the contact element la and which forms with the flanks la and la the insertion openings a and b.
  • the legs lb and lb of the contact yoke 1b are at their flanks lb' and lb", facing the contact element la, also formed as sharp-edged contact knives.
  • At the lower end of the contact assembly 1 there extends downwardly a terminal strip lab.
  • the contact yoke lb To ensure a satisfactory resiliency of the contact yoke lb, there are provided gaps or loops c and d between the yoke legs and the contact element.
  • the legs of the contact yoke lb are, in the range where the conductor is inserted, slightly divergent to thus form insertion slots a and b.
  • the contact assembly 1 may be a stamped unit and is preferably made of a highly conductive copper alloy.
  • the latter is threaded through the contact yoke lb and is positioned on the support faces e, and f, or g and h, which form part of the contact yoke lb and the contact element la.
  • the guiding means for conductor 3 is provided on the one hand, by the inner flanks of the contact yoke legs lb or lb" and, on the other hand, by the rounded end portion la of the contact element la.
  • the insulated conductor (or conductors) 3 is, by means of a pusher slide (not shown), pressed into the wedge-shaped slot opening a and b which has a width slightly smaller than the diameter of the metal conductor 3a.
  • FIG. 2 the embodiment shown therein differs from the previously described embodiment merely in that two separately stamped parts are used for the yoke and the contact element. In their assembled condition, however, the two parts form an integral mechanical and electrical unit.
  • Both the contact element 4 and the yoke 5 have a respective, planar, plate-like integral lower part 4a and 4b which are in a face-to face relationship and may be welded together.
  • the thus unified plate-like parts 4a, 4b are embedded in the carrier body 2.
  • the contact element 4 is bent out of the plane of its associated plate 4a to extend in a coplanar manner with respect to yoke 5.
  • the relatively large contact area between the aforenamed two parts ensures a small contact resistance which, in turn, is the measure for a reliable electrical contact.
  • the terminal strip 4b forms a unitary part with the contact element 4. in H6. 3 there is shown an embodiment of the invention adapted to receive up to four conductors between leg portions of a twin contact yoke 7 and flanks of a twin contact element fi. Both parts may be stamped components.
  • the embodiment shown therein includes a wire yoke 7b with an interposed contact element 6b for receiving two conductors and further includes a unitary wire yoke 7a integral with the wire yoke 7b.
  • the wire yoke 7a does not contain an interposed contact element. Consequently, a conductor inserted in the yoke 7a is contacted at both, diametrically opposed sides, by opposed leg portions of yoke 7a.
  • the embodiment according to FIG. 5 comprises integral tripple yokes 7c, 7d, 7e.
  • the yokes are upwardly closed and are united at their lower end to form a platelike member.
  • a clip connector terminal for insulated conductors comprising:
  • a wire yoke in the shape ofa closed loop said wire yoke including two leg portions constituting two of said contact members which surround at least partially said central contact element, with each leg portion extending along either side of said central contact element with the knife edge on each leg portion cooperating with the knife edge of the immediately adjacent side of said central contact element, and resiliently yielding in a direction away from its cooperating contact member upon insertion of said conductor, said electric contact being maintained by a resilient force urging each leg portion towards its cooperating contact member, said yoke and said central contact element both having a plate-like terminal portion bonded together faceto-face, with said central contact element being bent out of the plane of its associated plate-like terminal portion and extending coplanar with said yoke between the leg portions thereof;
  • a clip connector terminal for insulated conductors comprising:
  • C. means joining said contact members at one end' remote from the loop connection between said leg portions; and D. insulated carrier means in which said last-named end of said contact members is anchored.
