Definitions

  • the present invention relates to end caps, more generally called lugs, attached to the ends of electrical conductors to ensure the connection between a distribution source and a device for use.
  • the invention relates, more particularly, to the ends which are used in the electrical harnesses of ignition of engines, such as the internal combustion engines and with spark ignition, in particular for motor vehicles.
  • connection between the supply harness and the members it connects takes place in directions different from those corresponding to the axes of the connection terminals. with olive outlet, especially when the overall size or the space available requires it.
  • the bent end pieces generally used are parts obtained by stamping. Such end pieces have an "L" shape, at right angles or obtuse, and include a branch for connection with the wire of the harness and a branch for connection with the connection terminal. Such ends are satisfactory for the electrical connection function and serve as intermediaries for transmitting the tensile forces when it comes to disconnecting the wire from a connection terminal.
  • Another solution consists in crimping the lugs at the ends of a wire and then in threading the caps by subjecting them to an elastic deformation sufficient to ensure the passage of the bent edge of the lugs.
  • US Pat. No. 2,024,814 describes a straight end piece having a tubular connection branch having a series of axial slots delimiting tongues in the portion of a cylindrical wall.
  • the end of this branch is open to allow the axial introduction of the connecting olive, for example a candle.
  • the relative maintenance after engagement is ensured by the combination of a local conformation of the tongues and by their elastic reaction capacity.
  • the connection branch has, moreover, a hole of radial axis partially formed in two tongues contiguous to the right of the local conformation to allow a radial engagement of an olive.
  • the tongues thus tend to open relatively by radial expansion and no longer assume the dual function of mechanical strength and electrical contact for which they are designed.
  • Such a end piece comprises a connection branch of tubular shape, split axially and open at its end for the axial engagement of the olive. a candle. On either side of the slot, openings are made for the engagement of protuberances formed by a split ring, a kind of clip surrounding the branch. These protuberances assume the function of stops for the clip and for the olive. The reaction to the elastic deformation of the clip is used to make the branch assume the functions.
  • This structure has several drawbacks.
  • the present invention aims to remedy the known drawbacks of end caps or lugs of the prior art and proposes, in order to assume the function in the above-mentioned technical field, to use a straight end cap specially made for per put a corner or axial connection with a connection terminal.
  • An object of the invention is to provide a tip or thimble of a general straight character with great ease of adaptation and which can be fitted with a protective cap of the straight or angled type.
  • Another object of the invention is to provide a straight end piece for electrical connection which can be produced at an attractive cost price, in large series.
  • Yet another object of the invention is to provide a straight end piece for electrical connection capable of supporting a large number of successive connection and disconnection operations without altering its electrical and mechanical connection capacities with the connection terminals.
  • An additional object of the invention is to provide a new straight tip for electrical connection which allows easy and automated assembly of the protective caps, whether the latter are straight or bent.
  • Fig. 1 is a perspective of the object of the invention.
  • Fig. 2 is a transverse view taken substantially along the plane II-II of FIG. 1.
  • Fig. 3 is a perspective illustrating the implementation of the object of the invention according to FIG. 1.
  • the right end piece of electrical connection comprises a branch 1 of crimping on an insulated electrical conductor, such as a wire of a combustion engine ignition harness. It should be considered that the subject of the invention can find a different application from that above given solely by way of nonlimiting example.
  • the crimping branch 1 comprises, for the purpose of connection with the conductor, two crimping wings 3 which can be folded down and clamped on the insulated conductor to provide mechanical resistance and establish electrical contact with the conductive element.
  • the crimping branch 1 is extended by a connecting branch 4 of generally cylindrical tubular shape extending coaxially to the branch 1 and of diameter greater than that of a connection terminal 6.
  • the connection branch 4 is obtained by a rolling operation of the corresponding part of the metal blank from which the branches 1 and 4 are formed.
  • connection part 4 defines an aperture 5 which may be in alignment with the open section of the wings 3 or be shifted year ulairement g.
  • the opening 5 is intended for the engagement of the connection terminal 6, illustrated in FIG. 2, in the form of a suitable olive on the end of a spark plug.
  • a terminal 6 comprises a frustoconical bearing 6a terminating by its large base in a cylindrical part 6b followed by a frustoconical bearing 6c oriented opposite to the bearing 6a.
  • the frustoconical bearing 6c leads to the bottom of an annular groove 6d whose particular function will be highlighted in the following.
  • the opening 5, associated with at least one elastic locking means 7 intervening in the passage section, is executed so as to extend up to the level of the open transverse end 13.
  • the opening is formed over a depth radial less than the radius of the branch and thus defines, in the peripheral wall of the branch 4, two lips 18 parallel to each other and to the axis A having two longitudinal edges 19 which extend above a diametral plane P 'passing through axis A (fig. 1).
  • the edges 19 thus define between them an engagement passage corresponding to the opening 5.
  • the edges 19 represent elastic locking means of a terminal 6 and, for this purpose, are supplemented by the presence of two bosses 20 executed at starting from the external face of the corresponding lip to project on the internal surface of the branch 4.
  • the two pairs of bosses 20 facing each other are executed, in addition, so that those, located in position of not opposite visJ are spaced slightly less than the diameter of the bottom of the groove 6d from the terminal 6.
  • the lips 18, the edges 19 and the bosses 20 assume the functions of elastic clamp and electrical contact.
  • Fig. 3 shows that the relative engagement of the terminal 6 between the bosses 20 allows for an elbow connection from the straight end piece according to the invention while providing a possibility of relative orientation at an angle different from 90 °.
  • connection branch 4 and a terminal such as 6, is obtained by ensuring the relative introduction of the terminal 6 in the direction of the arrow f inside the opening 5, c ' that is to say in a substantially radial direction relative to the axis A of the branch 4.
  • the bearing surface 6a engages between the bosses 20 and causes the elastic opening of the lips 18.
  • L 'maximum engagement of the terminal 6 inside the branch 4 is determined by the contact of the 6th face with the part of the wall of the branch substantially opposite the opening 5 relative to the axis.
  • the bosses 20 enclose the terminal and cooperate with the groove 6d and the bearing 6c. This results in maintenance of the terminal 6 by tightening with establishment of an electrical contact.
  • the conformation of the lips 18 makes it possible to confer stable and reproducible elastic deformation characteristics.
  • the tip can thus be assembled and disassembled many times without altering its qualities of maintenance and electrical contact.
  • provision may be made to form, in the branch 4 and opposite the opening 5, a stamped 11 having a flat bottom 12 to cooperate with the 6th side.
  • the lateral connection zones between the deep-drawn 11 and the cylindrical profile of the branch increasing the resistance to elastic deformation and give the lips 18 a function of elastic clamp with clamping which is even more effective.
  • the object of the invention represents a nozzle of straight structure capable of ensuring an elbow electrical connection between a conductor and a terminal 6.
  • Another advantage of such an embodiment lies in the fact that the mounting of a protective cap on the wire can be carried out easily, by simple sliding on the straight end piece after crimping the end piece on the wire and checking the electrical qualities.
  • the opening 5 is axially longer than it is wide. It thus becomes possible to engage the terminal 6 in a direction inclined to the plane P and thus to make an electrical connection at an angle different from 90 °, the electrical contact being ensured at least by tightening the bosses 20.
  • Fig. 3 also shows that the branch 4 can also be used when it is necessary to ensure a straight connection.
  • the terminal 6 can be engaged axially along the arrow f 4 from the open transverse face 13 so that the first bosses 20 appearing assume a clamp function by engaging inside the annular groove 6d ; the other two bosses serve to limit the penetration of terminal 6 along axis A and participate in the electrical contact function.
