2 Claims. (Cl. 206--56) This invention relates to electrical connections. More particularly, this invention provides an improved system for uniting electrical leads with terminal posts.
Heretofore, electrical connections have been formed by clamping a clip around an electrical lead and a portion of an electrical terminal post so as to unite firmly the the three elements. Automatic and hand-held tools have been provided for positioningthe clipv around the lead and post to form the connection. In one prior process, the clips have beenfed to the tool in continuous strip form, wherein the clips are directly united in end-to-end fashion, so that successive clips can be sheared or fractured oif the strip. In another prior process, it has been known to feed the clips to the tool on a portion of sheet material wherein the clips are attached to the sheet material at spaced distances thereon.
The present invention resides in the concept of an improved feed material for carrying the clips to the tool and a method of forming .electrical connections with the feed material.
In the feed material according to the invention, the clips are frictionally and releasably held on projections formed at spaced distances along the length of a carrier tape. The invention has various uses. It is particularly appropriate for the maintenance and repair of electrical equipment, and development of novel prototypes, wherein one or only a few connections need be formed at a given time. The strip material according to the invention can be employed witha simpler tool than is required when using clips directly attached to each other in strip form.
According to the invention, the clips vare only frictionally held on the carrier tape, and thus a small force of the tool is required to remove the clip from the tape for subsequent uniting with the lead and terminal post. There is no requirement for the machine elements neces sary to shear or fracture a clip from a continuous strip.
For a better understanding of the invention and its other objects, advantages and details, reference is now made to the presently preferred embodiment of the invention which is shown, for purposes of illustration only, in the drawings.
In the drawings:
FIGURE 1 is a fragmentary enlarged perspective of the feed material according to the invention;
FIGURE 2 is an enlarged perspective of a portion of the feed material shown in FIGURE 1;
FIGURE 3 is an elevational view looking into the outer end of one of the clips frictionally held on a projection of the carrier tape, as seen in FIGURE 1;
FIGURE 4 is a fragmentary transverse section on the line 44 of FIGURE 2;
FIGURE 5 is a perspective illustrating the method of the invention and showing a roll of feed material according to the invention being fed to an assembling or uniting tool; and,
FIGURE 6 is a perspective of an electrical connection formed according to the invention.
Briefly stated, the feed material of the invention includes a carrier tape and a plurality of clips removably carried on the tape. holes formed therein for engagement by the sprocket of an advancing wheel to feed the material to the tool. The tape has a plurality of spaced projections extending 3,227,270 Patented Jan. 4, 1966 from one side thereof. Each projection is wedge-shaped. The clips are formed in a generally-tubular shape so as to surround and frictionally engage a projection of the tape.
According to the method of the invention, the feed material is moved in a step-by-step manner to the tool. An electrical lead is also fed to the tool. The tool is positioned adjacent an electrical terminal post. The tool is then actuated to slide a clip from one of the projections of the tape. Thereafter, the tool unites the lead and post by clamping the clip around them.
sheet material- Among the sheet materials which can be employed are paper, synthetic resin plastics, and the like. The carrier tape 26 includes a body portion 28 having formed therein a series of square-shaped holes 30 at uniformly-spaced distances for engagement by the teeth of a sprocket wheel formed on tool 16, where- The tape has a plurality of spaced by the carrier tape 26 is advanced in a 'step-by-step fashion through a slot 34 in tool 16 during the connecting method.
For supporting the clips 18, a plurality of projections or fingers 36 are formed on carrier tape 26 and extend at uniformly-spaced distances from one longitudinal edge of body portion 28. Each projection 36 includes a top surface 40, an opposite bottom surface 42, two sides 44, and an outer end face 46. Each projection 36 has a general wedge-shape, its sides 44 converging away from the body portion 28. The sides 44 form an angle of about 1 degree with planes perpendicular to the lengthwise dimension of body portion 28.
Each clip 18 has a substantially uniform cross section along its length so as to frictionally engage the projection 36 upon which it is supported, and be readily removed therefrom by a small dislodging force applied by an element of tool 16.
Each clip 18 is of generally-tubular shape with a bore 50 in the center. Each clip 18 includes a back plate 52 having a ridge 54 formed at the center of one end thereof. The ridge 54 is shaped to form a slot 56, as seen in FIGURE 3, for receiving the end of the electrical lead 20 in the finished connection shown in FIGURE 6. Each clip 18 further includes two panels 57 joined to opposite edges of back plate 52. Flanges 58 of curved form extend inwardly from the lower edges of the panel-s 56. Except for ridge 54, each clip 18 is of uniform cross section along its length.
In the method of the invention, the clips 18 are slid onto projections 36 of carrier tape 26 to forma releas able friction fit. The assembled feed material 10 is formed into a coil or roll 12 and mounted on the shaft 14 of tool 16, as seen in FIGURE 5. The tool is actuated to advance the feed material 10 into slot 34. An electrical lead 20 is fed down from above into groove 60 of the tool. The tool 16 is then positioned adjacent terminal post 22, which will generally be mounted in a terminal board (not shown). The tool 16 is then actuated, whereby a clip 18 is pushed 01f of its projection 36 and moved to a position where the end of lead 20 is received in slot 56 and the terminal post 22 is received in the bore 50 of the generally-tubular clip 18. The curved flanges 58 clasp or clamp the terminal post 22 in the bore 50 and firmly into electrical connection with the end of lead 20.
The tool 16 is then withdrawn and is ready for a subsequent actuation to form another connection. 1
Thus it will be seen that the invention provides a feed material and a method for forming electrical connections with simplified procedures and apparatus.
While a presently preferred embodiment of the invention has been illustrated and described, it will be recognized that the invention can be otherwise variously embodied and racticed within the scope of the following claims:
