SOLDERING LUG Filed Nov. 3, 1944 Patented May 25, 1948 lS'OIiDERINGTUG sQarl' Gs'Andersongllhicago, lll.,.assignor to ,.RaymondiT.1.Moloney,:Chicago, :Ill.
Application November 3, 194:4,Serial No. 5611712 2 Claims. (Cl. 153-324) This invention pertains to electrical connecting devices and has as its principal object the provision of an improved soldering lug.
Soldering lugs of a varietyf shapes anil type are known in the art somerarerattached aoitheir mounting by .means of interlocking certain =integral body parts thereof in holes formed in "the mounting; others are mounted by means of rivets passing therethrough and through the mountmg.
Connection or soldering lugs of the class herein described are frequently mounted on thin strips of insulation, for example, Bakelite strips, which may be 1 inch thick, or even less, and as little as inch wide; the length of such strips is variable, 6 to inch lengths being common.
The common practice in attaching soldering lugs to such thin, narrow strips, is to pierce the strips with a succession of holes spaced apart along the length of the strip at intervals corresponding to the spacing desired between the lugs; then upset portions of the lugs are passed through said holes and peened or crimped over. Rivets are frequently employed in place of the upset, extruded, or punched-out portions of the lugs.
A great objection to the aforesaid practices is that the (necessarily) thin insulating strips are greatly weakened by any piercing or imperforation therethrough, especially in the center regions thereof, and much breakage results both in themanufacture and use of this type of construction.
The lug of this invention overcomes the foregoing objections by providing mounting ears near opposite ends thereof and adapted to be bent over the edges of the narrow mounting strip, eliminating the necessity for central or medial imperforations in the body of the insulating strip.
Other objects, advantages, and aspects of novelty peculiar to the improved lug will appear as the following description proceeds in view of the accompanying drawing, in which:
Fig. 1 is a front elevational view of a number of lugs assembled on a mounting strip;
Fig. 2 is a rear elevational view similar to Fig. 1;
Fig. 3 is a side elevational view of the novel lug, to enlarged scale, taken in section through lines 3-3 of Fig. 1;
Fig. 4 is a perspective of the novel lug, to enlarged scale,
Referring to Fig. 4, the improved lug consists of a thin metal stamping including a central elongated body portion III terminating at oppos'ite ends :in -rev'ersly hooked lug portions I I and F2. Itf-will "be observed --that the lug portions M and 'FZa're offsetwith respect to each other, that is-to say, lug portion II lies on a side of a longitudina-l eenter line' through the main body of the stamping which 'is opposite from the side upon which the remaining lug portion I2 lies.
Adjoining each lug portion II or I2 is a corresponding ear Na and IZa (see Fig. 3 also), each struck from the body of the lug so as to lie on the open side of the corresponding slot Ilb or I211, forming the hook or lug proper, to which the electrical conductors are attached preparatory to soldering.
As illustrated in Fig. 2, the lugs are adapted to be mounted on a narrow strip I3 of insulating material, such as Bakelite, such strip being prepared by having punched along both longitudinal edges thereof, a plurality of notches I4, spaced in such manner that a notch will confront each ear portion Ila or I2a of each lug, when the latter are placed upon the strip.
The endwise portion IIX and IZX of each ear on each lug, are struck over and around the mounting strip, as shown in Fig. 2 and in the magnified sectional View of Fig. 3, thus securely fixing the lugs on the strip.
In Fig. 1 there is shown the front view (opposite to that of Figs. 2) of a terminal strip employing the new soldering lugs, from which it will be observed that there is a considerable flat area IBX of the lug disposed against the mounting strip in each instance, by reason of which there is some reinforcement of the thin strip. Since there are no perforations in the median body portions of the mounting strip, and since the depth of the notching l4 may be kept quite shallowmerely deep enough for the ear portions Ila and 12a to catch in and prevent longitudinal shifting of the lugsa stronger construction results than is possible with the same thickness and size of mounting strip in prior constructions wherein one or another type of median body imperforation is employed in locating or securing the lug The disposition of ear portions Ila and l2a in notches I4 prevents longitudinal displacement of the individual lugs, and disposition of said ear portions in offset relation at opposite ends of the lugs prevents rocking thereof.
By punching ear portions Ila, I 2a, and lug slots Ho and l2b from the same sides, respectively at each end of the lug, the die construction is simplified and material wastage minimized.
proved soldering lug,
While extremely simple in design structure and appearance, the novel lug fulfills a need in the art for a lug which will permit the use of relatively thin insulation strips by reason of the fact that such strips need not be weakened by imper- Having thus, described my invention in an imwhat I claim as new and x wish to protect by Letters Patent of the United States is:
1. A terminal strip including soldering lugs for electrical connections and comprising an elongated strip of insulation providing a mounting strip, said strip having notches formed along the opposite longitudinal edge portions thereof, and T 1 20 lug portions on said strip and each comprising an elongated piece of metal placed against said mounting strip crosswise of the latter, and each having an ear portion disposed on opposite sides thereof and turned back and over a corresponding edge portion of the strip in one of said notch portions, leaving a lug projection on each side of said strip, each said lug projection being disa 4 posed on a side of the longitudinal axis of said piece of metal opposite from the other said lug projection. V
2. A soldering lug for electrical connections and comprising an elongated strip of metal having mounting ear portions formed at opposite ends thereof by turning back an edge portion from each of said ends, but on opposite sides of the longitudinal axis of said strip, leaving lug projections at said opposite ends of the strip, each said projection being disposed on a side of the long axis of the strip opposite from the other,
and each said projection having a conductor notch formed therein and opening into the edge portion along which the corresponding ear portlon' has been turned back.
