Definitions

  • the invention relates to a method for producing contact elements in the form of contact spring sockets or spring-loaded plug pins, with a plurality of contact springs which are arranged next to one another and can be fixed at one end to a carrier part and which are curved for making contact with the mating contact.
  • the invention has for its object to provide a simple and inexpensive manufacturing process that enables multiple plug connections with small space requirements for the transmission of high currents despite small plug-in forces in a particularly efficient manner.
  • the manufacturing method according to the invention has the following method steps: arranging equally long Contact spring wire sections at a predetermined distance and in a mutually aligned parallel position, supplying a limiting band to at least one of the ends of the contact springs and connecting the contact springs to the limiting band during the advance of the contact springs transversely to the contact spring axis to form a contact spring mat, bulging of the contact springs transversely to the plane of the contact spring mat, Applying a galvanic coating, severing the delimitation band or bands to form contact spring units and transferring the contact spring units into a cylindrical, rolled form.
  • the individual supply of the contact springs to a socket body can advantageously be dispensed with.
  • the described way of creating the contact spring mat from contact spring wire sections, which are connected at the ends, also eliminates the considerable problem that has arisen when using a meandering contact spring mat, namely the conversion into a cylindrical shape, since there are no arcuate transition wire regions that are one oppose such cylindrical shape.
  • a torsional stress on the contact spring wire sections within the contact spring wire mat when it is converted into a cylindrical shape is also practically impossible. It is also no longer necessary to prefabricate cylindrical contact spring assemblies, as is proposed in DE-C-11 13 023.
  • the limiting band used is expediently made of a profiled shaped wire, the outer surface of which forms an acute angle with the axis of the contact spring wire sections. In this way, the outer surface of the shaped wire ensures that the mating contact is aligned eccentrically with respect to the contact element.
  • a particularly stable and safe design results if a limiting band is used, which is formed by a U-shaped copper band in cross section, the two legs of which enclose the ends of the successive contact springs between them.
  • the contact spring wire 1 which is used to produce the contact elements and is made of a copper-beryllium alloy, is directed from a coil 2 and cut into sections 4 of a corresponding length using a cutting tool 3. They are then moved further in the direction of arrow 5 transversely to their axial direction with the aid of a transport device (not illustrated in more detail). With the conveying speed of the sections 4, a limiting belt 8 or 9 is fed from the coils 6 and optionally also 7 to the front ends of the sections 4 moved forward at a predetermined distance from one another in the directed state. At schematically indicated fastening stations 10 and 11, the ends of the contact springs 4 are connected to the limiting bands 8 and 9, respectively, by welding, preferably laser welding, to form a contact spring mat 12.
  • the contact springs 4 are given a radial bulge transversely to the plane of the contact spring mat 12, the distance between the limiting bands 8 and 9 from one another reduced accordingly.
  • the contact spring mat 12 then passes through an electroplating station, of which pick-up or transport rollers 14 are illustrated schematically.
  • the contact spring mat 12 is given a high-quality finish, for example with gold, in the area of the contact points, with the aid of a schematically illustrated wetting device 15, which can be a titanium electrode with textile covering for wetting the contact points.
  • a mat section of the desired length is separated from the contact spring mat 12 with the aid of a cutting device 16 and is rolled cylindrically in a subsequent processing step.
  • Either the contact element thus formed takes the form of a spring-loaded plug pin 17 or, as illustrated in FIGS. 4 and 5, the shape of a contact spring bushing 18.
  • the cylindrical rolling process takes place in such a way that the radial bulges 19 are directed outwards, whereas in the second case they are directed inwards.
  • Fig. 6 it can be seen how the contact spring wire sections 4 are each connected on the end face with a limiting band 8 and 9 in the form of a round wire.
  • profiled shaped wires 8 ⁇ or 9 ⁇ can also be used as boundary bands. While the boundary band 9 ⁇ has a rectangular cross-section, the boundary band 8 ⁇ is shaped such that it lies laterally with a side shoulder 20 on the sections 4. The resulting broadening of the boundary band 8 'in conjunction with the inclined outer surface 21, which includes an acute angle with the axis of the contact springs 4, ensures that with eccentric approach of the counter-contact, not shown, for its precise alignment the contact element is taken care of.
  • FIG. 8 a modified embodiment is illustrated, in which the limiting band 8 or 9 is formed by a U-shaped copper strip in cross section, the two legs of which enclose the ends of the successive contact springs 4 between them. Furthermore, this FIG. 8 illustrates the possibility of combining two mat-like contact spring units over a central limiting band 22 common to them, forming a double unit which enables use as a double socket.
  • FIG. 9 very schematically shows the possibility of arranging the contact element in the form of a spring-loaded plug pin 17 on a carrier pin 23.
  • Flanged edges 24 and 25 serve to secure the position of the spring-loaded plug pin 17.
  • FIG. 10 shows the possibility of using the contact element designed in the form of a contact spring bushing 18 in a carrier bushing 26, and FIG. 11 illustrates the fixing of two contact spring bushings 18 in a coaxial position within a double carrier bushing 27 common to them.
  • the carrier pin 23 and the carrier bushes 26 and 27 are, as shown in FIGS. 9 to 11, turned parts produced in a conventional manner.
  • contact springs 4 e.g. the contact elements in the form of the contact spring bushing 18, on the other hand, have the advantageous possibility of being inserted into sleeves prefabricated as a drawn part with a wall thickness of 0.1 mm and being fixed in them by simply flanging the sleeve edges. This can also be done in connection with pressing the one sleeve edge onto a comparatively simpler support pin.
