Filed Mar. 8, 1968, Ser. No. 711,694 Int. Cl. H01r 13/34 US. Cl. 339-95 Claims ABSTRACT OF THE DISCLOSURE An electrical grounding terminal has leg members provided with serrations thereon for cleaning a hole in a metal member in which the terminal is forcefully driven to provide an excellent electrical connection therebetween and for securing the terminal in the hole.
This invention relates to electrical terminals and more particularly to electrical grounding terminals for connection with grounding planes or the like.
In a number of fields, ground connections are necessary and these are formed in various ways. One way is the soldering of a wire to a ground plane. Another way consists of wrapping the end of a wire around a screw or bolt on a ground plane and tightening the screw or bolt. A further way involves applying a terminal to an end of a wire and securing the terminal to a ground plane via a screw or bolt.
These approaches are time consuming and are not reliable in that a cold solder joint could result and the screws or bolts could work loose thereby resulting in an improper ground connection. The areas for the ground connection may be dirty which would create problems with continuity and the connection may be impaired due to the presence of oxide coatings.
An object of the present invention is to provide a grounding terminal which overcomes the drawbacks of the prior art devices.
Another object of the invention is the provision of a grounding terminal which is easily terminated in a ground plane.
A further object of the invention is the provision of a grounding terminal that cleans the area in which the termination is to be effected during the making of the termination.
An additional object of the invention is to provide a grounding terminal that is locked in position.
A still further object of the invention is the provision of a grounding terminal that exerts positive retention pressure at all times once it has been driven into a ground plane.
Still an additional object of the invention is to provide a grounding terminal having stop means to prevent over insertion of the grounding terminal in a ground plane.
A still additional object of the invention is the provision of a grounding terminal having staggered teeth means to accommodate various thicknesses of ground planes.
Other objects and attainments of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings in which there are shown and described illustrative embodiments of the invention; it is to be understood, however, that these embodiments are not intended to be exhaustive nor limiting of the invention but are given for purposes of illustration in order that others skilled in the art may fully understand the invention and the principles thereof and the manner of applying it in practical use so that they may modify it in various forms, each as may be best suited to the conditions of a particular use.

FIG. 21 illustrates the embodiment of FIGS. 17 through 20 being used as a fastener.
Turning now to the drawings and especially FIGS. 1 through 6, a grounding terminal GT comprises legs 1 and 2 which are connected together by a split tapered body 3, legs 1 and 2 being appendages extending outwardly from the opposing edges of the split. Saw tooth serrations 4 are provided along legs 1 and 2 and projections 5 are provided in the body 3 opposite the inner ends of the serrated areas of the legs. An outwardly-directed protrusion 6 is formed in body 3 adjacent projections 5. Wings 7 extend outwardly substantially at right angles from the large end of body 3 as well as a shank portion 8 which terminates in a ferrule section 9 for engagement with the wire and insulation of conductor means (not shown) to be secured therein via conventional crimping techniques.
In use, grounding terminal GT is forcefully driven into an aperture 10 of a grounding plane 11 which is generally of sheet metal. Wings 7 serve as a driving surface against which a hammer or like instrument is applied to drive the grounding terminal in position. Of course, wings 7 need not be present since the large edge can be engaged by the driving means. Legs 1 and 2 are directed away from each other, as illustrated in FIG. 3, so that they are springably moved toward each other when body 3 is driven into aperture 10. Tapered body 3 wedgingly secures the grounding terminal in position along with serrations 4 and the configuration of serrations 4 is such that they facilitate driving the terminal in the aperture but they prevent the grounding terminal from backing out of aperture 10 once it has been driven thereinto.
Projections define stabilizing means to stabilize body 3 in aperture and protrusion 6 acts as a stop means to limit the movement of body 3 into grounding plane 11. Of course, protrusion 6 can be eliminated and wings 7 can serve as stop means. The spring characteristics of the body 3 provides constant spring pressure to legs 1 and .2 so that a constant retaining force is present at all times. Serrations 4 not only lock body 3 in position in grounding plane 11 but they also clean the area of contact so that good electrical conductivity is established. Body 3 can be driven into various thicknesses of grounding planes as a result of its tapered configuration. Grounding terminal GT can be driven into a grounding plane without the application of special tooling or by an unskilled laborer and without preparing the ground plane to clean the area in which the connection is to be made.
It should be noted that protrusion 6 need not be provided in body 3 to permit further insertion of the body into the sheet metal panel if such is necessary because serrations 4 can be provided along the lengths of legs 1 and 2. Also, because of the reduction in diameter and the compression of body 3 when inserted into the grounding plane, the grounding wire could be inserted into the grounding plane, the grounding wire could be inserted in aperture 10 prior to grounding terminal GT being driven in position therein thereby obviating the necessity for shank portion 8 and the ferrule section 9. The serrations on one leg member can be axially spaced relative to the serrations or the other leg member so that the serrations can bite into the grounding plane at axially-spaced locations.
FIG. 7 illustrates grounding terminal GTa which is an alternative embodiment of grounding terminal GT. Grounding terminal GTa. is similar in every respect to grounding terminal GT except that no stabilizing projections are provided on body 341 although they can be provided thereon and protrusion 6 is replaced with an opening 12 while the legs are provided with extensions 13. Opening 12 and extensions 13 define stop means to limit the movement of body 3a within opening 19 of grounding plane 11.
FIGS. 8 through 12 illustrate grounding terminal GTb which is a further embodiment of the invention. Grounding terminal GTb includes a base 14 from which shank portion extends for connection to an electrical conductor means and oppositely disposed leg members 16. Base 14 defines a body connecting the leg members together. As can be discerned, leg members 16 are V-shaped with the bases of the VS being directed toward each other and serrations 1'7 are provided along each of the tapered edges of leg member 16. Recesses 18 are located at the inner ends of serrations 17 to provide stop means to limit the movement of the grounding terminal in ground plane 11. Since leg members 16 have a V-shaped configuration, spring pressure is obtained when pressure is applied to the two edges thereof when forcefully driven in aperture 10 of grounding plane 11. Serrations 17 are angles so as to permit easy insertion when installed and they lock the grounding terminal in position. Serrations 17 are preferably staggered to provide a firm termination and retention in various sheet metal thicknesses.
As the ground terminal is forcefully driven into aperture 10 of grounding plane 11 via the application of the force-driving member such as a hammer or the like against base 14, legs 16 perform as V-shaped springs thereby obtaining resilient action via the spring characteristics of the legs thereby maintaining constant pressure of the terminal against the grounding plane. The legs are shaped and proportioned so that pairs of serrations may be deflected toward the center of the aperture a certain amount and no further to assure broaching action.
FIGS. 13 through 16 illustrate grounding terminal GTc which is similar in construction in every detail to grounding terminal GT1] except that base 14a has an outwardly directed arcuate configuration and an oblong opening 19 therein. Arcuate base 14a, upon being forcefully hit by a hammer to drive grounding terminal GTc into aperture 10 of grounding plane 11, is deformed causing leg members 16a to be spread outwardly in aperture 10 thereby applying outwardly-directed forces on the leg members to more effectively secure the terminal in the grounding plane. Opening 19 provides a weakened area of base 14a so that base 14a can readily assume a substantially flat configuration after being driven into grounding plane 11 as illustrated in FIG. 16.
FIGS. 17 through 2.1 illustrate grounding terminal GTd which is an additional embodiment of the invention. Grounding terminal GTd is provided with a central planar section 20 from which arcuate-shaped leg members 21 extend. Section 26 defines a body connecting the leg members together. Leg members 21 extend outwardly from planar section 20 in such a manner that the combination of planar section 20 and leg members 21 form an S-shaped configuration in cross section as illustrated in FIG. 20. Leading edges 22 of leg members 21 are tapered to facilitate the insertion of the grounding terminal in position in an aperture of a grounding plane. The trailing ends of leg members 21 are bent substantially at right angles to form wings 23 to provide force-driving surfaces against which a force-driving member engages to drive a terminal into position in a grounding plane. One of wings 23 can be provided with a shank portion and ferrule section for securing onto an electrical conductor means.
Outwardly extending projections or serrations 24 are formed in leg members 21 and they are disposed at a slight angle with respect to the longitudinal axis of the terminal. Projections 24- in the leg members 21 are arranged such that the terminal can be threaded out of engagement with a grounding plane by insertion of a screwdriver in space 25. The S-shaped configuration of the body of the grounding terminal applies constant pressure onto a grounding plane once the terminal has been forcefully driven thereinto.
As illustrated in FIG. 21, the embodiment of FIGS. 17 through 20 can be used as a fastener to fasten two members 26 and 27 together with member 26 being plastic or other flowable structural material. The fastener of FIG. 21 is forcefully driven into openings 28 and 29 of mem bers 25 and 27 with projections 24 biting into and flowing therearound to maintain the fastener secured in position therein. Wings 23 engage member 27 thereby securely fastening members 26 and 27 together. A screwdriver can be inserted into space 25 to threadably remove the fastener from member 26 thereby unfastening members 26 and 27. The fastener can also be threadably reinserted since projections 24 provide a self-threading feature. The springable characteristics of leg members 21 apply constant pressure against the Wall of opening 28 thereby securing the fastener in position therein.
It should also be noted that wings 23 are slightly bent toward the front end of the body so as to provide a resilient clamping force onto member 27. This feature abets the retaining characteristics and tolerates vibration and shock environments better than conventional solidthreaded fasteners or the like.
The embodiments described hereinabove are susceptible to mass production by automatic machinery and they are conveniently formed by shaping a sheet metal blank or strip of a suitable electrically conductive metal in successive forming steps. The metal is sufficiently hard and resilient to impart to the connection area a springlike character, yet it is sufliciently malleable to permit cold-forging or crimping of the ferrule section onto a conductor means to provide an excellent electrical and mechanical connection. The spring characteristics of the metal are such that the terminals apply constant compressive pressure onto the area in which they are forcefully driven.
It will, therefore, be appreciated that the aforementioned and other desirable objects have been achieved; however, it should be emphasized that the particular embodiments of the invention, which are shown and described herein, are intended as merely illustrative and not as restrictive of the invention.
