Definitions

  • connection device with an existing, such as plate or strip-shaped base body made of insulating material, which is penetrated by openings between opposite sides, which define connection levels, into which contact elements can be inserted, which have at least one on each side of the base body
  • Have fork contact section which is connected to a further contact section of the contact element via a strip-shaped connecting section running parallel to the connection planes and is transversely displaced by the connecting section against the further contact section and in which the base body on the side of the fork contact sections expands the openings for a suitable reception which has connection and calender contact sections.
  • connection device is known from DE-OS 27 38 869.
  • a necessary transverse offset of the respective contact sections of the contact members is made possible by strip-shaped connecting sections of the contact members, the strip-shaped connecting sections with their strip width being arranged at right angles to the connection planes.
  • the transition points between the connecting sections and the contact sections of the contact members are flexible and the contact members can be inserted with different angular positions of the connecting sections, in particular with respect to the contact contact sections provided for contacting a ribbon cable single conductor, in the insulating body of the connecting device provided for receiving them.
  • this object is achieved in that the fork contact sections formed as flat parts, each with two legs lying in one plane, are bent out of the plane of the strip-shaped connecting sections arranged parallel to the connection planes with the strip width and by means of a 90 ° bend that the leg planes of the individual fork contacts are designed to be rotatable about the axis of the torsion stem by a torsion stem provided between the respective fork contact and the respective connecting section.
  • leg planes of the fork contacts are inclined at an angle of approximately 15 ° to the connecting line of the contact organ openings in the base member which are provided at least in a row next to one another.
  • This inclination of the fork contacts relative to the direction of the conductors that are to be connected to the fork contacts creates a certain adaptability of the connecting device to conductors with thicknesses that differ from one another within certain limits, since a thinner conductor matches a narrower one due to the inclination of the fork contacts in the direction of progression Contact slot is found, while a thicker conductor can enlarge the contact slot between the fork contact legs by a slight torsion of the fork contact legs, which is made possible due to the inclination of the fork contact.
  • FIG. 1 The figures, seen in an oblique view and in a rough schematic illustration, omitting all the details not necessarily necessary for understanding the mode of operation of the subject of the innovation, show a strip-shaped base body 1 made of insulating material, in particular of thermoplastic plastic, which is between opposite sides (in the figures) only one of these sides can be seen) 2,3 is penetrated by channel-like openings 4. These openings 4 are for Inclusion of contact elements 5 is provided which form on the side 2 of the base body 1 fork contacts 6, into which, ie in their contact slot 7, a conductor can be pressed with a course parallel to the side 2.
  • the contact members 5 are e.g. formed into contact pins, each of which protrude concentrically to the axis 8 of an opening 4 from the base body 1.
  • These contact pins can e.g. connected with contact springs of a contact spring strip or inserted into grid holes in a circuit board.
  • the contact pins of the contact members 5 and the contact springs of a contact spring strip there must be distances between the contact pins which correspond to the distances between the contact springs. These distances between the contact pins are of importance here, in particular, the distances of the contact pins from one another transversely to the direction of travel of a ribbon cable, but in some cases do not match the distances of the individual conductors of a ribbon cable.
  • the contacting slots 7 on the side 2 of the base body 1 must therefore have a different spacing from one another than the contact pins on the side 3 of the base body 1.
  • the contact members 5 are between the contact section, which e.g. is formed by a contact pin and which is arranged concentrically to the axis 8 of an opening 4, and the fork contact 6 is provided with strip-shaped connecting sections 9 which run parallel to the side 2 of the base body 1.
  • the fork contact sections 10 of the contact members 5 provided at the other end of the connecting sections 9, with their contacting slots 7, are located exactly at the point of travel of a ribbon cable single conductor, even if the distance between the individual conductors and the distance the contact members 5 deviate from one another on the side 3 of the base body 1.
  • connection section 9 The respectively required angular position of the connection section 9 in a plane parallel to the side 2 of the base body 1 is predetermined by groove-shaped extensions 11 of the openings 4 on the side 2 of the base body 1, since the connection sections 9 fit exactly into the groove-shaped extensions 11 and thus the fork contact section 10 adjust each contact element 5 individually by simply inserting the connecting sections 9 into the extensions 11.
  • the fork contacts 6 formed as flat parts, each with two legs 12 lying in one plane, after the insertion of the contact members 5 into the openings 4 and the connecting sections 9 into the extensions 11, also take different directions with their leg levels , since the fork contact sections 10 are each bent out by means of a 90 ° bend out of the plane of the strip-shaped connecting sections 9 arranged parallel to their side with their width.
  • This alignment of the fork contacts 6 can advantageously e.g. be made with the aid of a cover plate 14, which, by virtue of its connection to the base body 1, locks the connection sections 9 in the extensions 11 and thus the contact members 5 in the openings 4 of the base body 1.
  • this cover plate 14 namely passage slots are provided for the fork contacts 6, which automatically turn the fork contacts 6 with the plane of their contact legs in the same desired direction when the cover plate and base body 1 are joined in a correspondingly helical shape.
  • leg planes of the fork contacts 6 at an angle of approximately 15 ° (cf. in particular FIG. 3) against the direction 15 of the connecting line 16 of the contact organ openings 4 provided in a row next to one another To set base body 1 at an angle.
  • the inventive design of the contact members 5 makes it possible to use completely identical contact members 5 to populate a base body 1 of a connecting device for ribbon cables.
  • the contact members 5 can be inserted completely tension-free and uncomplicated into the openings 4, which are provided for receiving them, or into the extensions 11 of the openings 4.
  • the fork contacts 6 are then placed parallel to one another and are brought in an optimal direction with respect to the direction of the ribbon cable.
  • Both the ribbon cable and the round cable can be contacted with the connecting device, the individual conductors of the round cable being spliced and arranged on one level next to one another.
  • Such a bracket can e.g. have a receiving slot for the ribbon cable, in which the ribbon cable is guided and held so that each individual conductor is assigned to a recess of the bracket, which is provided for receiving the free ends of the contact legs 12 of a fork contact 6.
  • a bracket provided for contacting the individual conductors of a round cable can have plug openings assigned to the individual conductors, as a result of which the individual conductors are assigned to the fork contacts 6 when the bracket is connected to the base body 1.
