Each of the projections 4 2 by means of an attaching member 3 assembled has a twistable portion 20 forming an extension with the condenser can adjacent its lower end of the spacing portion l1 and adapted to project and providing a plurality of projecting portions through an opening I of the mounting plate.
4 extending beyond the lower end of the can Each of the twistable portions 20 has a pair of and through the plate 2 and providing means enelongated support-engaging elements or lugs 2| gaging the rear face 5 thereof (Fig. 3). The integral with opposed sides of the projecting mounting plate 2, which may be of metal or portion and disposed normally in the plane of plastic material, has a central opening 6 and a the projecting portion. Each of the lugs 2i has 05 plurality of narrow openings 1 disposed around one end integrally joined to the twistable portion and its opposite end free and in normal position in adjacent relation to the spacing portion II.
Attachment of the condenser can I to the mounting plate 2 is quickly and easily accomplished by moving the projecting portions 4 through the apertures 1 until the shoulders l8 engage the upper surface IQ of the mounting plate adjacent the apertures 1. Next the portions 20 of the projecting portions 4 extending beyond the rear face 5 of the mounting plate are twisted by a suitable tool (not shown) to move the lugs 2i out of the normal plane of the projecting portions to engage tightly behind the surface 5. One of the features of my invention is embodied in the particular dimensions of portions of the attaching member wherein the normal length I of the lugs 2| is greater than the distance between the points of junction of the lugs with the portions 20 and the rear face 5 of the mounting plate when the projections 4 extend through the openings 1 and before twisting. As a result of.
these relative dimensions of the parts, the lugs are bowed after twisting of the portions 20 so as to take up variations in thickness of the mounting plate 3 and at the same time draw the condenser can tightly against the mounting plate 2.
The soldering terminals II have a relatively straight flat body portion 22. Attaching means in the form of a flange or foot portion 23 integrally joined to one end of the body portion extends in right-angular relation to the normal plane of the body portion. The foot portion 22 is adapted to be held between the insulating plates l3 and H, as most clearly shown in Fig. 3, so as to maintain the terminal in assembly with the condenser can and in upright position. A pair of spaced wing portions 24 integrally joined to opposed side edges of the body portion extend out of the normal plane of the body portion. The wing portions 24 are adapted to be bent to embrace a connecting lead (not shown) between the foil of the condenser and the soldering terminal prior to soldering the connecting lead permanently to the body of the terminal. The connecting leads are adapted to extend from the foil of the condenser through openings (not shown) in the insulating plates l3 and i4 into said soldered engagement with the terminals ll. Integral with the opposite end of the body portion 22 from the foot portion 23 I have provided an outwardly-extending wire-supporting means or lip portion 25. The lip portion extends be yond one side of the body portion 22 and has a lower open face 26 adapted to support the bare wires 21 of the leads 28 (Fig. 7) so that'the bare wires may be soldered thereto.
Although I have set out the preferred use of my improved attaching member in connection with an electrolytic condenser, it is understood that the part may be used in combination with units of manufacture of other shapes and forms. Furthermore, I perceive that projecting portions I embodying one or more features of my present invention might be formed integrally with the lower end of the condenser can i so as to effect a satisfactory attaching means for securing the unit to a panel.
Although I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby because the scope of my invention is best set out in the following claims.
1. Incombination, a support, a part to be secured to said support and attaching means for securing said part to said support, said attaching means comprising projecting portions extending beyond the outermost margins of an end of said part, each of said projecting portion: passing through an opening in said support and having integral lug-shaped support-engaging elements adjacent its opposite edges and normally in the plane of said projection, said elements having free end portions facing said. end of said part and spaced therefrom, and said projections being twisted on the opposite side of said'support from said part to dispose said support-engaging elements behind said support.
2. In combination, a support, a part to be secured to said support and an attaching member for said part, said attaching member comprising a base portion secured adjacent an end of said part and projecting portions extending from said base portion beyond the outermost margins of said end, each of said projecting portions having a twistable portion passing through an opening in said support to a position beyond the lower surface thereof and having integral lug-shaped support-engaging elements adjacent its opposite edges and normally in the plane of said projection, said elements being joined at one end to said twistable portion and having a-free end at its opposite end facing said base and spaced therefrom, the length of said support-engaging elements being greater than the distance between the points of junction of said elements with said twistable portion and said lower surface of said support, and said twistable portions being twisted to dispose said support-engaging elements behind said support, and said elements being bowed by said twisting action.
3. In combination; a support. a part to be secured to said support and attaching means for securing said part to said support, said attaching means including a projecting portion extending beyond outermost margins of anend of said part, said projecting portion passing through an opening in said support and having an integral bendable lug-shaped support-engaging element ad jacent one edge and normally in the plane of said projection, said element having a free end portion facing said end of said part and spaced therefrom, and said projection being twisted on the opposite side of said support from said part to dispose said support-engaging element behind said support whereby the said element may ad just itself to the thickness of said support by bending relative to the, rest of said projection.
