Definitions

  • the invention relates to a connecting device for a plurality of insulated wires, with a housing made of insulating material, which has an input for a cable summarizing the wires and then a number of wires corresponding to the number of wires provided next to one another provided with provided in the housing, assigned to the receiving tubes, mutually parallel slots, which are aligned with their narrow sides to the receiving tubes and connect them to an outside of the housing, as well as with plate-shaped contact pieces, each of which from the outside of the housing with contacting one in one of the Receptacle-inserting wire are designed to be pressed into the slots and have barbs at their edges perpendicular to the receiving tubes for hooking the contact pieces in the housing.
  • connection device is such. B. known from DE-AS 24 32122.
  • contact is established between one of the contact pieces and further lines by bringing an external contact element into elastic contact with a back of a contact piece. Special precautions are required to ensure that the external contact element does not fail to reliably miss the relatively narrow back of the contact piece.
  • connection device of the type mentioned in such a way that, with an uncomplicated construction of the device, both the contact pieces can be reliably connected to the wires, and contact strips which are integrally connected to the contact pieces and which are easily electrically connected to an external contact element are created can be connected.
  • each contact piece has three contacting tips in the direction of travel of a wire, with free ends of the contacting tips which are only crosswise offset by bevels, that in a plastic body which can be locked with the housing on the side of the outer slot openings in this body by the Insertable, tongue-shaped contact sections are provided on the housing-facing side of the body and are integrally connected to the contact pieces via a web that has a smaller width than the contact pieces and the contact sections and are arranged in a plane parallel to the level of the contact pieces in the plastic body, and that the contact pieces are supported on the plastic body with shoulders provided between the contact pieces and the webs.
  • an auxiliary element is provided with the plastic body, which can be locked with the insulating material housing of the device, with which the contact pieces can be easily pressed into the housing slots for contacting the wires.
  • the shoulders of the contact pieces facing the plastic body and support surfaces of the plastic body facing these shoulders are dimensioned such that the contact pieces can be pressed slightly into the material of the plastic body.
  • the webs have a curved course and are freely guided in chambers of the plastic body and that between each contact section and each web a transitional section is provided which is wider than the contact section, forming shoulders of the transition section supported on the plastic body.
  • a force accumulator can be formed which keeps the contacting effect of the contact pieces constant.
  • the curved course of the webs serves to decouple the contact sections relative to the contact pieces, so that, for. B. vibrations acting on the contact sections can not easily affect the contact pieces and thus on the contact between the contact pieces and the wires.
  • the housing in an end region of the receiving tubes facing away from the cable entrance has a window-like recess connected to the outside of the housing and extending at right angles to the course of the receiving tubes, at least on one side of the receiving tubes points.
  • the device has an elongated plastic housing 1 with an end face 2 and longitudinal sides 3. On its side 4 opposite the end face 2, the housing is provided with an inlet opening 5 for a cable 6.
  • the cable 6 is preferably the connecting cord of a telephone set.
  • four wires 7, each surrounded by an insulating sheath, are arranged next to one another in a common insulating material sheath.
  • the common sheath of the wires 7 in an end section of the cable 6 has been removed, the end section being adapted to the length of receiving tubes 8, which are continued for one of the wires 7 next to one another the input opening 5 in the housing 1 between the end face 2 and the side 4 are provided parallel to the longitudinal axis of the housing.
  • lateral niches 10 are provided which enlarge the inlet opening 5 in sections.
  • the input opening 5 is provided with dimensions such that a distance remains between the walls of the housing 1 and the cable 6 in the region of the input opening 5, which can be potted with synthetic resin.
  • the niches 10 serve to anchor the hardening synthetic resin composition 11 and thus absorb tensile forces acting on the cable 6, which want to pull the cable 6 out of the housing 1.
  • the housing 1 is closed except for a window-like recess 9.
  • the window-like recess 9 extends from the side 12 to an end region of the receiving tubes 8 for the wires 7 facing away from the input opening 5 and is also cast and closed after the assembly and connection of the wires 7. The correct position of the wires 7 in the receiving tubes 8 can be observed through the recess 9.
  • the housing 1 On the side facing away from the upper side 12, the housing 1 is provided with a receiving contour for a plastic body 13 which is designed to be latchable with the housing 1.
  • slots 15 which are in the housing 1 between the receiving tubes 8 and the side facing away from the side 12 of the housing 1 Housing 1 are provided.
  • the slots 15 are each aligned with one of the receiving tubes 8, so that a contact piece 14 can penetrate through such a slot 15 with contacting tips 16 into a receiving tube 8.
  • Each contact piece 14 has three such contact tips 16, which are arranged one behind the other in the direction of travel of a receiving tube 8.
  • the free ends of the contact tips 16 are offset from one another only by bevels 30 such that the free ends of the two outer contact tips are somewhat to the left and the free end of the central contact tip is somewhat to the right of the axis of a receiving tube 8.
  • the contact tips 16 of a contact piece of a wire 7 inserted in a receiving tube 8 force a slightly meandering course when they penetrate into this wire.
  • the contact security between conductive parts of the wire 7 and a contact piece 14 is significantly improved.
  • the contact pieces At their edges 17, which face the narrow sides of the slots 15, the contact pieces have barbs which are pressed into the plastic material of the housing 1 when the contact pieces are pressed into the slots 15 and thereby lock the contact pieces 14 in the housing 1.
  • the contact pieces 14 sit with shoulders 19 on a surface of the plastic body 13.
  • the shoulders 19 and the surface areas of the plastic body 13 which come into contact with these shoulders 19 are matched to one another in such a way that the contact pieces 14 can be pressed slightly into the plastic mass of the plastic body 13 , when the resistance that a wire 7 opposes to the penetration of the contact tips 16 exceeds a certain level.
  • the shoulders 19 of the contact pieces 14 are formed in that the contact pieces 14 are connected to contact sections 21 only via narrow webs 20.
  • the tongue-shaped contact sections 21 are inserted into guide grooves 22 of the plastic body 13 in such a way that a central region 23 of the contact sections is exposed. With these central regions 23 of the contact sections 21, external contact members can therefore be easily connected, for. B. fixedly provided contact springs of a housing into which the plastic body 13 can be inserted with the area. in which the contact sections 21 are located.
  • the width of the tongue-shaped contact sections 21 is smaller than the width of the contact pieces 14 Clock sections 21 are inserted from the side into the plastic body 13 from which the contact pieces 14 protrude.
  • the free ends 25 of the contact sections 21 are bent around edges of the plastic body 13 and thereby hold the contact sections 21 in the plastic body 13 opposite to the insertion direction.
  • the webs 20 run between the transition sections 24 and the contact pieces 14 in a curved and freely guided manner in chambers 26 of the plastic body 13 and thereby contribute to the mechanical decoupling of the contact pieces 14 and the contact sections 21.
  • a movement of the contact pieces 14 when these contact pieces are pressed into the slots 15, the contact pieces 14 with their shoulders 19 being pressed against the plastic body 13, does not affect the contact sections 21.
  • a lever 28 which is integral with the plastic body 13 and resiliently resilient against the plastic body 13 and which interacts with corresponding counter-contours of a receiving housing for the device, holds the device in place in the receiving housing.
