Definitions

  • the invention as expressed in the title of this specification refers to a quick-connection terminal device for electrical connections, which provides the function for which it is intended with various advantages and characteristics of novelty, which will be explained in detail below, which are an improvement over the current state of the art in its scope.
  • the object of the present invention focuses specifically on a quick-connection terminal device essentially comprising of a metallic element whose obvious purpose is to provide a mean of a quick attachment of a cable to the terminal connector in an electrical connection without using a screw, said device having a simplified and innovative structural configuration that incorporates a flat elastic element specially designed to, among other advantages, facilitate such attachment while ensuring optimum and extensive cable contact with the metal surface of the device to ensure electrical conduction.
  • the scope of the present invention is encompassed in the industrial sector dedicated to the manufacture of appliances, electrical devices and mechanisms particularly in the area of the connecting elements.
  • examples of the aforementioned prior art include patent ES419361A1 , referring to an arrangement of a screwless terminal connector for electrical conduction, which essentially comprises a contact bridge arranged in a housing of insulating material and retaining spring supported thereon, that is, forming with the bridge, at least one fastening place for conductors, or also patent ES2193312T3 , which discloses a connector terminal for electrical conductors, which is essentially configured based on a casing of insulating material in which a metal contact element is housed with at least two clamping points, which are always formed between a leaf spring and a current rod common to all the clamping points.
  • the invention consists of a terminal connection device for electrical connections which is essentially constituted by a metallic body incorporating at least one elastic element for quick and screwless fixing, of at least, one conductor cable, with the particularity that said elastic element is a flat strip and the metal body is a bent and mechanized piece with a configuration specifically designed to accommodate the cable end ensuring perfect securing thereof with the flat strip and maximizing the area of contact of said cable with the metal surface of said body to provide optimal connectivity. All of this, with a metal body and a flat strip of very simplified construction and easy to assemble making the device a simple and cheap component to manufacture.
  • the metal body forming the device has an approximately C-shaped configuration which highlights a central straight section where the cable is inserted, an oblique lower section where the flat strip is incorporated oblique to the central section and therefore to the cable to lock on it, and a broken upper section acting as the cable stop and wherein there is at least one contact point for connecting the device with another similar device or with some other external element.
  • the metal body has at least one channel in the central straight section for receiving the cable which, introduced via the bottom of said central section, it engages with the upper edge of the flat strip, as said upper edge is facing said central section and is raised by the cable itself.
  • the upward cable penetration i.e. from the bottom of the metal body, determines the bending of the strip, as it tends to return to its naturally flat position, it is locked onto the cable fixing it.
  • any attempt to pull the cable down further strengthens its fixation with the strip.
  • the inclination of the strip with respect to the horizontal, or perpendicular line to the central straight section of the metal body is about 30° degrees.
  • the lower section of the metal element has a first initial section, which is perpendicular to the central straight section, thus obtaining a greater channel length with the same height of the metal body, and a second distal section that is oblique to the former section and tilted at 30 ° with regard to the same, wherein by means of a fixing means the flat strip is fixed and which achieves the tilting of the flat strip with regard to the perpendicular to the straight section.
  • the flat strip On the opposite side, the flat strip has an upper edge which is partially straight, and which locks on the cable, as this is inserted into the device, having a projection which provides a fulcrum to facilitate disengagement of the strip when the cable is to be released.
  • This projection when there is no cable, is inserted into a hole provided for this purpose in the central straight section of the metal body and the extraction of the cable is achieved by simply pressing on said projection through said hole.
  • the flat strip in its upper interlocking side is divided into two, providing two top interlocking edges, and the central straight section of the metal body is also configured to receive two cables, one on each side thereof, so each of them is fixed with one of the upper edges of the flat strip and they can work independently in both the locking and unlocking of the conductors.
  • central straight section presents a curved edge laterally defining an interior channel longitudinally embracing the cable providing an increase of the area of contact between said cable and said metal body along the entire central straight section, whereby the connection efficiency is improved.
  • the broken section referred to in this part has a bend at an acute angle, which inferiorly determines a converging housing for receiving the cable end once introduced along the central straight section.
  • This angled housing acts as a stop to limit the introduction of the cable, serving for different cable diameters through the converging configuration.
  • the described quick-connection terminal device for electrical connections is therefore an innovative structure of characteristics unknown until now for the purpose for which it is intended, reasons which linked to its practical usefulness, provide sufficient grounds for obtaining the privilege of exclusivity requested.
  • the device (1) in question comprises at least one metal body (2) incorporating at least one elastic element for the quick-connection of at least one cable (3).
  • the metal body (2) is a bent and mechanized C-shaped piece having in its central portion a straight section (2a) which receives and makes contact with an end portion of the cable (3) fixing it with an elastic element, which consists of a flat strip (4) disposed obliquely with respect to said straight section (2a), and such that, upon insertion of the cable (3), the upper edge (4a) of the strip folds and locks and fixes said cable (3), as shown in Figure 4 , the tilting of the flat strip (4) being of about 30° degrees with regard to the perpendicular to said straight section (2a).
  • the metal body (2) has a lower section (2b), where the flat strip (4) is incorporated being oblique to the central straight section (2a) and at 30odegrees to the perpendicular, and an upper broken section (2c) that acts as a stop for the cable (3) and which has at least one contact point (5), for the connection of the device (1) with a similar device or another external element.
  • the lower section (2b) of the metal element has a first lower initial section (2b1) which is perpendicular to the central straight section (2a) and thus obtaining a greater channel (21) length with same height of the metal body (2), and a second distal section (2b2) that is oblique and inclined at 30 degree with regard to the same, wherein the flat strip (4) is fixed and which achieves the tilting of the flat strip (4) relative to the perpendicular to the straight section (2a).
  • the underside of the flat strip (4) is incorporated in a coplanar manner, as fastening means the respective fins (24) bent inwardly which provided for this purpose press against the side of the underside of the flat strip (4) in coincidence with the respective coupling points (43).
  • the coplanar fixation of the flat strip (4) with the lower distal section (2b2) of the lower oblique section (2b) of the metal body (2) while determining the tilting of the flat strip (4) provides greater safety in the fastening and fixing of said flat strip (4) when working when bending due to cable (3) insertion.
  • the metal body (2) has, in the central straight section (2a), with at least one channel (21) to receive and accommodate the cable (3) making contact with the same throughout the length of the straight section (2a), which is determined by the existence of the circular recess (22) in the first lower initial section (2b1) and the existence of a curved side edge (23) in the central straight section (2a).
  • the top edge (4a) of the flat strip (4) is partially straight, to lock onto the cable (3), when the cable is inserted via the bottom of the central straight section (2a) of the metal body (2), having a projection (41) which provides a fulcrum to facilitate its unlocking and allow removal of the cable (3).
  • the flat strip (4) has a longitudinal section (42) which divides it into two by its upper side, determining the existence of a double upper locking edge with two projections (41), and in parallel, and the central straight section (2a) of the metal body also has two channels (21) to receive two cables (3), one on each side thereof, so that each is fixed to one of the upper edges of the flat strip (4).
  • the broken upper section (2c) of the metal body (2) has a bend at an acute angle (2c1) that inferiorly, determines a converging housing (26) to receive the end of the cable (3) once introduced along the central straight section (2a), adapting to different cable diameters (3), thanks to this convergent configuration.
