Definitions

  • This invention relates to improvements to electrical connections by means of which a large variety of circuit connections can be implemented both easily sand economically.
  • this invention proposes as a basic element on which the various elements described subsequently can be developed, a flexible metal lamellar connector shaped like the letter omega ( ⁇ ) having side ends curved outwards and two diametrically opposed holes in the rounded upper part on an axis which is transversal to the symmetrical axis of the connector.
  • this invention relates to a terminal strip for electrical connections to a conductor and a flexible contact for clamping the pins of a two-­pin electric bulb.
  • the conductors are constituted by round or polygonal rods they can act as a support for the bulb socket.
  • the support of the bulb-­holder simultaneously constitutes the electrical connection between the contacts and the conductors become complicated and expensive in terms of time and accessories.
  • the object of this invention is to constitute an anchorage for a conductor, to act as a support for a bulb by firmly clamping its pin and to permit optimal electrical conduction between the conductor and the bulb.
  • Another object of this invention is to effect a connection between two cylindrical bodies or bodies with a polygonal cross section without the aid of terminals, screws, bolts or other accessories.
  • Yet another object of this invention is to create an anchorage for a conductor and, at the same time, act as a support for a bulb, clamping tightly its pin; thus permitting optimal electrical conduction between the conductor and the pin of the bulb, eliminating the use of the bulb socket and various accessories.
  • the conductor which, in this case, has a round cross-section is indicated with (1)
  • (2a) is the terminal in a preferred embodiment in which (3) indicates the part which constitutes the flexible metal lamellar terminal strip and which anchors the conductor (1) and carries the current.
  • the part which acts as a flexible contact is indicated with (4) also clamps a pin (6) of the bulb (5) and, in the case proposed in figures 1 and 2, is at right-­angles to the terminal (3).
  • the terminal (3) is omega shaped ( ⁇ ) with the ends curved outwards to permit the grasping of a cylindrical body or a body with a polygonal cross-section of the appropriate diameter and dimensions, its flexibility guaranteeing efficient conduction of electricity.
  • the part called the flexible contact (4) has a closed-U conformation (see fig. 7-8) with an appendix (10) which curves outwards permitting the insertion of the pins (6) of the two-pin bulb (5), one pin into hole (8) and one pin into hole (9).
  • the pins (6) can be inserted into the flexible contact (4) in two ways:
  • the pins (5) can be orientated through an angle of 360° around the axis (7) of the conductor (1).
  • the invention is shown in some of its embodiments and it can be seen that the main parts (3) and (4) can be arranged in a large variety of ways according to the type of application requested.
  • This invention can be easily obtained from sheets of harmonic steel by cutting and bending operations.
  • the terminal according to this invention thus combines in a single metal, conducting and flexible body a terminal for electrical connections which carries out the function of supporting a two-pin bulb when used in pairs.
  • the terminal 2a can be coupled to a clip on terminal 2n, and arranged one at each end of a section of conductor 1 to form a connecting bridge for a bulb which straddles the two main line conductors 1a which can be parallel to one another (fig. 9a) or one perpendicular to the other (fig. 9b).
  • a first embodiment of the connector is marked (21), (22a) and (22b) are the ends which are curved outwards, (23a) and (23b) are the opposed holes on an axis (x) which is transversal to the symmetrical axis (y), while (z) is the longitudinal axis of the connector (21).
  • fig. 13 shows the invention in one possible use as a connector of two cylindrical bodies at right-angles to one another.
  • Fig. 13 shows the cylindrical body (24) which has been passed through the holes (23a) and (23b) and the second cylindrical body (25) inserted subsequently between the curved side ends (22a) and (22b) of the connector (21) which, being made from a flexible metal material, grips the body (25) pressing it inwards against the body (24).
  • the connector of this invention is used to connect together two electrical leads, the electrical connection between the lead (24) and the lead (25) is guaranteed by the pressure exerted by the ends (22a) and (22b) on the conductor (25) which is pressed inwards against the lead (24) and, simultaneously, by the metal connector (21) by way of the surfaces in contact in the areas relating to (22a), (22b), (23a), (23b).
  • Figures 14 and 15 show the connector when utilised in a pair to electrically connect a two-pin bulb to two electrical conductors.
  • Fig. 16 shows a cross-section of a second embodiment of the connector of this invention, in which it can be seen that the upper part (28) has been flattened in order to create a larger contact surface between the connector and the body (24) inserted in the holes (23a) and (23b).
  • the embodiment shown in figure (16) is to be preferred when it is necessary to guarantee optimal conduction between the bodies (24) and (25) in the presence of high electrical currents.
  • Figure 17 shows a variant of the connector according to this invention characterised by the fact that it has side apertures (23c) and (23d) in the place of the holes (23a) and (23b), which start from the same position as the holes (23a) and (23b) and extend to the ends (22a) and (22b) which, in this case, become doubled into (22a, 22c) and (22b, 22d).
  • the embodiment shown in fig. 17 is to be preferred when two cylindrical bodies at right-angles to one another have to be connected and it is impossible to insert one of them into the holes 23a and 23b in the way shown in figures 13 and 16.
  • the body (24) is simply inserted perpendicularly in the apertures (23c) and (23d) and the connector is pressed onto the body (25) by means of the ends (22a, 22c) (22b, 22d), which will allow the body (25) to pass and will then elastically press it against the body (24).
  • the connector of this invention can be easily obtained from a metal sheet by cutting and bending operations and it can be used as a terminal for two cylindrical bodies at right angles to one another, or as an electrical connection for two transversal electrical leads or, when utilised in pairs, as a conductor support for the pins of a two-pin bulb.
  • terminal and connector of this invention can also be constructed from materials other than those proposed in the description and also in forms and for objects other than those shown in the attached drawings while still remaining within the scope of this invention as defined in the claims attached hereto.
