Definitions

  • the subject of the present invention is a contact element for a terminal block comprising a head having an opening, a nut situated under the underside of the head, a screw which is screwed into the nut and situated on the side of the upper face of the head. , and an elastic part formed by at least two electrical contact blades.
  • the spacing between the two blades is not fixed and depends on the spacing of the two terminal block partitions and on the force they exert on the blades.
  • the problem posed by the invention consists in producing an optimized contact for terminal blocks whose nominal spacing of the blades is not dependent on the force exerted by the partitions or by the tightening of the screw in the nut.
  • the invention proposes an optimized contact for terminal block comprising an arm located between the head of the contact and the elastic blades, this arm being connected to only one side of the head and making it possible to dissociate the tightening functions of the screw for the electrical contact functions with the terminal block.
  • the blades have an intrinsic nominal spacing which depends on the manufacture and no longer on the pressure exerted by the walls.
  • the invention thus relates to a contact element for a terminal block comprising a head having an opening, a nut situated under the underside of the head, a screw which is screwed into the nut through the opening and situated on the side of the face. upper part of the head, and an elastic part formed by at least two electrical contact blades, characterized in that it has an arm extending from one side of said head, said elastic part being disposed at a distal end of the arms and said blades having a given nominal spacing.
  • the head of the contact element may include an opening having, over at least part of its circumference, a region whose diameter is less than the diameter of the screw, so as to allow friction of the internal face of the opening on the external face of the screw in order to prevent any untimely tightening or loosening of the screw in the nut due to external vibrations.
  • the elastic part can be formed by four blades which face two by two.
  • the nut is of polygonal shape and the head of the contact element has at least one side wall in which is cut at least one locking slot, so that at least one of the side edges of the nut is housed in at least one of said slots to block any free rotational movement of the nut.
  • the invention also relates to a terminal block having a main body having at least one housing for contact element, characterized in that it comprises at least one contact element of the type presented above, said contact element being arranged in at least one of said housings.
  • the terminal block may include at least two contact housings of different length in which are respectively arranged two contact elements whose arms are of different length.
  • the contact element 1 ' has a main head 3' under which is located a nut 6 '.
  • Blades 5 ' allowing electrical contact, are obtained by folding the lateral parts 4' of the head.
  • One of the side parts 4 ' has a bend 42' allowing the support of said side part on a flange 26 'formed in the body 2' of the terminal block.
  • Curved parts 51 ′ located at the level of the blades 5 ′, facilitate electrical contact with the connection elements of the terminal block (not shown).
  • This type of contact element 1 'for the terminal block has many disadvantages: the large number of folds made at the level of the head 3' and the lateral parts 4 'weaken the contact element as soon as it is manufactured; the existence of these folds at the rim 26 'does not allow to obtain precisely 5' blades having exactly the same length; the nominal spacing between the two strips 5 'is not defined intrinsically to the construction but depends on the spacing and therefore on the pressure exerted by the side walls 22' and 23 'of the terminal block on said strips 5'; similarly, a more or less significant tightening of a screw (not shown) in the nut 6 'causes a variation in the pressure exerted on the lateral parts 4' and therefore a modification of the spacing and the length of the blades 5 '.
  • the contact elements for terminal blocks according to the prior art cannot have a constant nominal length and deviation.
  • the numerous pressures exerted on the lateral parts 4 ′ and the blades 5 ′ weaken the contact element, which results in a loss of elasticity and a shorter service life of said contact elements.
  • FIGS 2 and 3 show a terminal block and an optimized contact element according to the invention which overcomes the aforementioned problems that appear in the contact elements according to the prior art.
  • the contact element 1 according to the invention has a head 3 in which is cut an opening 31 allowing the passage of a screw 7 for screwing in a nut 6 located under the underside of the head.
  • the screw 7 has a plate 71 allowing the external electrical contacts which are fixed between said plate 71 and the upper face of the head 3 to be held in position.
  • One side of the head 3 is extended in the form of an arm 4 perpendicular to said head 3.
  • At the distal end 41 of this arm 4 are blades 5 of electrical contact. In the invention described, these blades are in the form of two pairs of blades facing each other.
  • the opening 31 cut in the head 3 has over at least part of its circumference a region whose inside diameter is slightly less than the outside diameter of the screw 7.
  • An oblong opening such as that shown in Figure 3 is perfectly suitable .
  • This oblong shape introduces resistance to screwing and unscrewing preventing untimely screwing or unscrewing of the screw 7 in the nut 6 which could occur due to the external vibrations exerted on the terminal block.
  • the head 3 has two folded side edges 32 and 33, forming a U with the main face of the head, in which two slots 34 are cut.
  • the nut 6 is of polygonal shape and is housed under the head in space formed by the two lateral edges 32 and 33 in such a way that two of the lateral edges 61 of the nut are locked in the two slots 34. This device makes it possible to obtain a rotation lock of the nut 6 during screwing or unscrewing the screw 7.
  • the invention also relates to a terminal block capable of receiving this type of contact element.
  • This terminal block has a main body 2 having housings 21 intended to receive the optimized contact elements 1.
  • a protective cover 24 covers the housings 21 in order to protect the contact elements 1 from shocks and dirt. Openings 25 are made in said cover 24 to allow easy access to the screws 7.
  • the spacing between the blades 5 is obtained intrinsically by manufacture and no longer depends on the pressures exerted by the walls 22 and 23 of the body 2 of the terminal block.
  • the pressure exerted on the head 3 can no longer modify the spacing between the blades 5.
  • the nominal spacing of the blades 5 depending neither on the head 3 nor on the arm 4, the arm 4 can take all the lengths necessary to adapt to the housing 21 provided in the body 2 of the terminal block without the length or the spacing of the blades 5 having to be changed. This makes it possible to manufacture terminal blocks having housings 21 of different size, as shown in FIG. 3, allowing said terminal block to adapt perfectly to the location in which it will have to be installed.
