Definitions

  • the present invention relates to an automatically producible electrical connector with contact springs which are firmly connected to current conductors and possibly a protective conductor of a supply line by means of a crimp / crimp connection.
  • Such plugs are used to connect an electrical device to a mains socket and thus to the energy supply system of the power plant.
  • the corresponding connection cable i.e. the consumer line is coupled to the mains socket via a protective contact plug and to the device itself via a generic device plug.
  • an electrical connector is known with an insulating housing that contains spring chambers open to the outside, in each of which a contact spring is inserted, the contact springs being connected on the one hand to the current conductors and the protective conductor of a supply line, and on the other hand so Are designed to receive plug pins of a mating connector of an electrical device to be connected
  • the insulating material housing consisting of an inelastic molded part which has the spring chambers and a plug part which insulates the contact points between the contact springs and the conductors of the supply line and partially overlaps the inelastic molded part, and one in front the injection molding of the plug part onto the inelastic molded part is provided, which carries the contact springs according to the arrangement of the spring chambers, in such a way that on the one hand these spring into the spring chambers agen and on the other hand protrude on the second side of the holding plate and serve as connecting pins for the conductors of the supply line.
  • a device plug without a protective contact is known, the plug bridge of which is designed in such a way that the above-mentioned danger is avoided at least for two-pole device plugs.
  • hooks are formed or molded in the middle area of the plug bridge, one of which - one of the two connecting pins - projects beyond.
  • insertion funnels are arranged coaxially with the bores of the connecting pins located under the hooks. With the help of the two insertion funnels, all the individual wires of the two strands are conveyed into the respective holes so that they can be crimped there.
  • the object on which the present invention is based is to design insertion aids for a three-pin connector, as is known from DE-U-87 15 0 ⁇ 0 ⁇ 3, in such a way that both the abovementioned dangers are kinked due to the insertion of the conductor and thus possibly laterally protruding individual wires can be avoided from the outset, and automatic production with short cycle cycles is also possible.
  • the holding plate has two webs facing each other in the direction of the connecting pins, that the webs are connected to one another on their free side with a cover plate lying parallel to the holding plate, the cover plate being congruent to the holding plate , and that a conical through hole is provided in the cover plate coaxially to the connection pins, which serves as a funnel-shaped insertion aid when inserting the stripped conductor ends into the connection pins.
  • the device plug 1 consists of a two-part insulating material housing, namely an inelastic molded part 2 and an elastic, partly overlapping sprayed-on plug part 3 (which is shown transparently in the drawing).
  • the connector 1 With the inelastic molded part 2, the connector 1 is inserted into the mating connector of an electrical device to be connected; the plug part 3 receives a supply line 4, the second end of which is generally connected to an earthed plug, which is then to be inserted into the mains socket.
  • the inelastic molded part 2 consists of a head part 5, which ultimately serves as a handle part for handling the device plug 1, and a collar part 6, via which the elastic plug part 3 is injected or molded.
  • the head part 5 and the collar part 6 are offset against each other by a circumferential bead 7.
  • the collar part 6 has circumferential projections 8 which ensure an intimate connection between the plug part 3 and the molded part 2 and thus the tensile strength between these parts.
  • So-called spring chambers 9 are provided in the interior of the molded part 2, into which approximately U-shaped contact springs 10 are inserted or inserted. Via these contact springs 10, the connector 1 is plugged into the mating connector of an electrical device and the contact springs 10 grip resiliently and frictionally over the contact pins of the mating connector.
  • the contact springs 10 extend on the one hand close to the first end face of the molded part 2; on the other hand, they protrude beyond the second end face covered by the plug part 3 and here form connecting pins 11 for the line connections of the supply line 4 (cf. reference number 17).
  • the contact spring 10 is inserted in a holding plate 12, which is inserted in a form-fitting manner in the second end face via a shoulder 13 and a complementary undercut 14 on the molded part 2 or inserted into the second end face.
  • This overlap area can be clearly seen from the sectional side view in FIG. 1.
  • complementary locking means can be provided in addition to realize an additional frictional connection between the molded part 2 and the holding plate 12.
  • said and known holding plate 12 is further developed in such a way that it surrounds the connecting pins 11 in a cage-like manner, this holding plate 12 being connected to a cover plate 20 arranged parallel to it, and at such a distance that this cover plate 20 is connected to the Pins 11 on or stands up.
  • This cover plate 20 is also equipped with coaxial to the covered pins 11 provided conical through holes 21, which when completing the connector 1, d. H. when inserting the stripped conductor ends serve as an insertion aid. Via the funnel-shaped through holes 21, the conductor ends can be easily and securely inserted, and moreover into the connecting pins 11 in short machine cycle times.
  • the length of the webs 22 corresponds - as already mentioned - to the length of the connecting pins 11 projecting beyond the holding plate 12.
  • the cage-like molded part 30 is open between the webs 22, so that after the conductor ends have been inserted into the connecting pins 11, these are connected to one another, for example can be crimped.
  • the material thickness of the cover plate 20 is selected so that in the event that, contrary to expectations, a single wire should turn over when the stripped conductor ends are inserted, this is safely behind the upper edge of the corresponding through hole 21 disappears, that is, it cannot protrude.
  • the cage-like molded part 30 consisting of the holding plate 12 and the cover plate 20 will be explained again on its own with reference to the construction drawing according to FIG. 2.
  • the holding plate 12 itself has the mentioned approach 13, via which a positive connection to the inelastic molded part 2 is achieved.
  • the holding plate 12 - on two opposite sides - has a pair of webs 22, which in turn are connected to one another at their free ends via the cover plate 20.
  • the conical through holes 21 are integrated, in such a way that either annular projections 24 with the through holes 21 are provided coaxially to the position of the connecting pins 11 - cf. the graphic representation - or that the cover plate 20 itself is chosen so thick that the through holes 21 are deep enough to capture bent individual wires. It is essential with respect to the through holes that such - contrary to expectations - bent individual wires safely disappear behind the front edge of the through holes.
