Definitions

  • the present invention refers to a quick connection system for electrical contacts by incorporation of a spring for fixing the direct fit conducting wire in the electric current conduction metallization without using any other components or any subsequent folding process, thus allowing a greater simplicity and modularity when compared to the existing systems in the market, as it will be described further ahead.
  • connection between the metallization and the spring that fixes the conducting wire against said metallization la made in several different ways.
  • the third component comprises an area, which allows the housing of the spring as well as other areas that ensures the fixing of the spring in the metallization by fit.
  • the contact metallization comprises openings through which thin areas existing in the support metallization go through. After the positioning, these areas are folded in order to prevent the detachment of the set.
  • the assembly process referred herein implies the handling of a higher number of components when compared to the invention, apart from involving a bending process to ensure the fit.
  • Document EP1536519 discloses a quick connection system comprising a spring incorporating support places in a claw shape, two securing tabs and a contact metallization with an opening.
  • US3497923 discloses a U-shape cable clip comprising two outwardly splayed limbs and an aperture.
  • the quick connection system invented allows a quick installation by using a spring, which ensures the contact of the conducting wire on the electric current conduction metallization, being innovative in the solution used for its fixation ( Fig. 2 ), which makes the system simpler when considering several aspects that will be described further ahead, also allowing a high modularity and compact dimensions, important advantages in systems that might have little space to accommodate the referred connection system.
  • the present invention is characterized in that it comprises a spring ( Fig.3 ) incorporating support places in a claw shape (1) and (3), the first of which, as well as the conducting wire securing tabs- (2), is flexible.
  • the flexion of this support (1) allows the passage of both supports through an existing opening (4) in the contact metallization ( Fig. 4 ) . After the entry of the spring and the force that causes the flexion of the claw-shaped support (1) has ended, it recovers the initial position being fitted in the metallization together with the support on the opposite side (3), preventing the exit of the spring through said opening (4).
  • securing tabs (2) ensure the position of the claws (1) and (3) on the opposite side of the metallization immediately after the assembly and during the use of the system without the need to support the spring from below or sideways.
  • the force of the tabs (1) and (3) against the opening sides (4) is not sufficient to ensure the accommodation of the spring or when additional stability of the set is required, there can be made, as shown on Fig. 5 , recesses (5) and (6) on the periphery of the opening (4) on the sides where the claws (1) and (3) are filled.
  • the claws (1) and (3) entering said recesses (5) and (6) its positioning is more stable.
  • this invention by being simpler in the assembly than others, assumes a particular importance bearing in mind that all of the componento involved in this type of systems present small sizes and complex shapes.
