Definitions

  • ABSTRACT A clip operable to connect an electrical terminal post with a bus strip comprises:
  • the clip is operable to connect an electrical terminal post to .a bus strip, and comprises:
  • the arms preferably extend longitudinally upwardly so as, to receive the bus strip downwardly therebetween, and the..post passing opening is preferably located proximate the top of the hook shaped section, oneedge of that opening located in approximate alignment with one of the arms so that, the post will extensively contact the latter; also the hook shaped section preferably includes an S-shaped tang having a channel shaped cross section to receive one side of the post in such a way as to confine the post and urge it toward full and effective contact with the arm, as described.
  • Additional advantages include interlocking of the bus strip and clip to permit release of the clip from the strip as may be desired; and multiple dimples on the strip to interact with the clip as will be described.
  • FIG. 1 is a frontal elevation
  • FIG. 2 is a top plan view
  • FIG. 3 is a side elevation taken in section on lines 3-3 of FIG. 1;
  • FIG. 4 is a side elevation of the clip shown in FIGS. 1-3.
  • FIG. 5 is a section through the strip seen in FIGS. l3.
  • the clip as illustrated includes a channel section 100 having opposed longitudinally upstanding arms 11 and 12 between which the bus strip 13 is receivable.
  • the latter has a generally rectangular cross section and is vertically elongated, as shown.
  • the clip may with unusual advantage consist of Berillium copper, and be heat treated for strength. Its overall height H is typically less than 0.25 inch, one height dimension of unusual advantage beingabout 0.130 inch, giving a maximum length for wire wrapping on interfitting electrical terminal post 14.
  • Strip 13 may be about 0.025 inch in width and about 0.075 inch in height.
  • The'clip also includes a generally hook-shaped section 10b integral with one of the arms, as for example the upper extent 12a of arm 12.
  • Section 10b extends arcuately upwardly and laterally forwardly at 15 to slightly overhang the space 16' between arms 11 and 12, then upwardly and laterally rearwardly at 16, then downwardly and laterally rearwardly at 17, then downwardly and laterally forwardly at 18 toward arm 12, and then downwardly and laterally rearwardly at 19 away from arm 12.
  • the arcuate extents 15, 16 and 17 are preferably circularly curvedfwith outward convexity, and the arcu'ate extents 18 and 19 have outward concavity.
  • the sections'17, 18 and 19 define a tang with generally S-shaped curvature.
  • the tang is resiliently supported by circular curved sections 15 and 16 so as to be resiliently deflected to FIG. 3 condition upon interfitting reception of the post.
  • the hook-shaped section contains a top opening 20 to pass the post, as better seen in FIG. 1.
  • a horizontal and downward cut may be made in curvedsections 16 and 17, reducing the widths of such sections well below the overall width of the clip, facilitating the resilient support of the S- shaped tang, as described, as by two spaced and curved portions of sections 16 and 17.
  • the forward edge 20a of the opening is located in longitudinally vertical alignment with arm 12 as viewed in FIGS. 3 and 4.
  • the S-shaped tang has a channel shaped cross section at 22 laterally opposite arm 12 to receive one side of the post when the oppositeside of the latter engages the arm 12 as also seen in FIG. 3.
  • the forward extents 19a of the tang lower section 19 extend proximate or engage the rearward side of the arm 12, as is clear from FIG. 4, and the recess 22a defined by the channel shaped cross section facilitates endwise guided reception of the post between the tang and the arm 12, and through the opening 20, especially in view of the normally very small size of the clip.
  • the channel shaped section 10a of the clip normally closely receives the bus strip, as seen in FIGS. l-3, between arms 11 and 12; further, the clip and strip may advantageously have interlocking tongue and groove interfit.
  • a boss or dimple 24 on the strip is receivable into a recess formed by the other arm 11 upon relatively downward reception of the strip into space 16 between the arms 11 and 12.
  • the recess may be defined by a lateral through opening 26 in arm 11, and the boss or dimple on the strip may have a leading edge defining a cam shoulder 24a tapered in the downward direction so as to facilitate resilient temporary spreading of arm 11 away from arm 10 as the strip is urged downwardly into space 16.
  • the boss or dimple Upon completion of recpetion of the strip into space 16 as seen in FIG. 3, the boss or dimple is fully received into recess 26, and arm 11 springs back into place. Conversely, arm 11 may be pulled forwardly to release the strip.
  • Multiple spring clips may be rapidly assembled onto a boss strip as seen in FIGS. 1 and 2, and multiple wirewrap posts 14 received by such clips.
  • Such posts are preferably polygonal (such as square) in cross section to present edges for making good contact with wire turns wrapped about the posts.
  • Additional advantages of the strip and clip over known devices include: greater maximum current carrying capacity; minimum overall height; capability for interfit at selected or varying intervals along the strip; capability for quick assembly, disassembly and reassembly by a fabricator to accommodate to his needs; obviates the need for new tooling for each different progression of clips on a bus strip; each part can be separately plated; the strip may be relatively heavy to enable carrying greater current for the same loss; the strip can be easily produced with bosses or dimples at varying and selected spacing; the strip 13 can be fabricated from square, round or rectangular cross section stock, or from bare, plated or insulated metal; and the strip can be produced in continuous or selected lengths.
  • said hook shaped section including a tang extending downwardly at the lateral side of said one arm opposite the other arm of the channel shaped section, the tang also laterally aligned with said other arm, said hook shaped section containing an opening to pass said terminal post in vertically oriented relation between said tang and said one arm.
