Definitions

  • the invention relates to an electrical contact arrangement according to the preamble of claim 1.
  • Such contact arrangements are preferably found with a large number of connection points distributed over the length of a multi-core cable and a corresponding number of multi-pole connection plugs for the parallel power supply of consumers, especially low-current and / or low voltage consumers such as lamps and the like, is widely used.
  • a contact arrangement of the aforementioned type is known from DE 30 19 060 A1.
  • There, only one insulation recess is provided per connection point between two adjacent wires of a flat cable.
  • At diametrically opposite edge areas of an insulation recess both conductors are exposed, forming appropriate contact points.
  • Each connector has only one plug contact, which comprises two contact elements diametrically opposite one another in the plug cross section, elongated transversely to the longitudinal direction of the conductor and separated from one another by an insulating body.
  • the two contact elements common plane can be adjusted between a switch-on position oriented transversely to the longitudinal direction of the conductor and a switch-off position oriented parallel to the longitudinal direction of the conductor.
  • the safety of the contact maintenance is in need of improvement, because the two-pole plug contact is essentially only frictionally secured in its switched-on position and therefore cannot guarantee reliably constant contact surfaces.
  • there is also a desire for increased dielectric strength between the conductors or cable cores in the area of the connection points which is quite limited in the known embodiment because of the comparatively small distance between the contact elements of the plug contact, especially in a humid environment.
  • the object of the invention is therefore to create a contact arrangement which differs from the known through increased contact reliability and possibly through increased dielectric strength distinguished.
  • the inventive solution to this problem is characterized by the features of claim 1 and claim 5.
  • the exemplary embodiments shown show applications of the invention on a conductor arrangement in the form of flat cables with flexible or flexible insulation and embedded, likewise correspondingly flexible cores as conductors to be contacted.
  • other types of conductor arrangements are also possible, e.g. Lines with dimensionally stable or essentially only plastically deformable, in particular wire or rod-shaped conductors.
  • the flat cable 1 consists of an insulation 2, in which two wires 3a and 3b running next to one another are embedded.
  • the insulation penetrating between the two wires is symmetrical to the longitudinal central axis of the Cable-arranged recesses 2a and 2b are punched out, each of which exposes contact points K of both wires at diametrically opposite edge regions.
  • a two-pole plug 5 with two connection lines 6a and 6b inserted into the connection point 4 comprises an insulating body 7, within which the end sections 8 of the connection lines are connected by clamped or soldered connections 9 to an associated contact element 10a or 10b.
  • the latter together with an essentially cylindrical insulating element 11a or 11b, form plug contacts 12a or 12b, which are embedded with their upper end sections in the plug insulating body 7 and with their lower sections penetrate the insulating recesses 2a or 2b.
  • the insulating elements 11a, 11b each form a conical head 13, which rests with its upper shoulder on the underside of the cable insulation and secures the plug in its connection position.
  • the head diameter is dimensioned in such a way that the elastic flexibility of the insulation enables the recesses 2a and 2b to be gripped through with tolerable effort and without damaging the insulation.
  • a peripheral depression 14 is formed, into which the exposed contact point area of the two wires engages, forming a comparatively large contact area in the area of the contact element 10a or 10b concerned.
  • the plug contacts 12a and 12b are provided on their cross-sectional circumference with contact and insulating elements which are opposite each other in pairs in the direction transverse to their connecting line and which are also arranged antimetrically with respect to this connecting line. This ensures that, despite the exposure of symmetrical contact points K of both wires within both insulation recesses, each plug contact or contact element can only connect to one assigned wire. It goes without saying that, if necessary, a plurality of contact elements can be provided next to one another on a plug contact, provided that the above condition for selective wire contacting is maintained.
  • the contact arrangement according to FIG. 3 corresponds to the embodiment according to FIGS. 1 and 2, which is why the same reference numerals are entered for the plug contacts and the insulation recesses receiving them in the position shown.
  • the embodiment according to FIG. 3 is further developed into a contact connection that can be switched on and off with the aid of additional insulation recesses 2c and 2d, which are each arranged directly next to the recesses 2a and 2b and connected to them by open passage areas 2e and 2f.
  • the connector with its plug contacts 12a and 12b is required to be moved in the direction of arrow P3 until the plug contacts snap into the insulation recesses 2c or 2d.
  • a recess is formed in the insulation, which consists of three insulation recesses 402a, 402b and 402c which are connected to one another via passage areas 402d.
  • the plug contact having two contact elements 412a and 412b is arranged to be movable between different positions, the contact elements snapping into corresponding insulation recesses and thus being held in the relevant position.
  • the insulation recesses form contact points K for the electrical connection of the contact elements, each with an associated conductor. This results in a wire-selective contacting, whereby advantageously simple and inexpensive contact elements can be used.
  • This contact arrangement is designed as a changeover switch with a contact-free central position.
  • the contact elements 412a and 412b can be connected to the conductors by transferring between positions I and II in opposite polarity can also be brought into the contact-free central position by shifting into the passage areas 402d, which are also designed as latching recesses. Decisive for the switching effect are fundamentally different arrangements of insulation recesses, each of which is assigned to a switching position.
  • the recess 402b is associated with the two recess arrangements according to switch position I and II with the advantage of a simple design.
  • the adjustment movement of the contact elements or the plug comprises a translatory and a rotary component.
  • the contact elements can also be arranged in a manner known per se on a common plug element with a suitable insulating body.
  • the cutout in the cable has a comparatively large, central passage area, to which several smaller snap-in recesses with contact points for receiving the contact elements are connected.
  • a wide flat cable 501 with insulation 502 and reinforced central insulation web 501a and with two wires 503a and 503b is provided.
  • Such an embodiment is particularly advantageous for higher operating voltages.
  • two insulation recesses 502a and 502b which are only spaced apart in the transverse direction of the cable, form a contact point K with only one associated wire each, so that simple, continuously conductive plug contacts can be used.
  • This contact arrangement is also designed to be switchable on and off with the aid of additional insulation recesses 502c and 502d, which are arranged to overlap with the recesses 502a and 502b.
  • the switching movement of the plug contacts or of the plug is rotational as a result of the selected outline design and mutual position of the recess arrangements 502a / 502c and 502b / 502d according to arrows P5a and P5b, which may be desirable.
  • two insulation recesses 702a and 702b there are two insulation recesses 702a and 702b, the circumference of which extends at a distance from two flat cable conductors 703a, 703b.
  • Two associated plug contacts 712a and 712b are each provided with a cutting element protruding contact element 710a or 710b on circumferential areas oriented in opposite directions to one another in the cable transverse direction, which extends along the plug contact section engaging in the relevant insulation recess.
  • the regions of the cross-sectional circumference of the two plug contacts which are arranged diametrically with respect to the contact elements 710a, 710b are designed to be insulating or are provided with insulating elements which are complementary to the contact elements.
  • the contact elements and insulating regions are arranged antimetrically to one another with respect to the conductor arrangement, so that each contact element, when inserting the plug contacts 712a, 712b rigidly connected to one another by a plug body (not shown) into the insulation recesses, only with the one assigned to it Cable wire 703a or 703b can come into contact.
  • the outer longitudinal edges of the contact elements cut through the comparatively thin layer of insulating material at the narrowest point between the contact plug and the wire, so that the cutting edges ensure reliable contacting.
  • two plug contacts 912a and 912b are provided with blade-shaped contact elements 910a and 910b, however a projecting contact cutting edge is present in each case on two diametrically opposite regions of the cross-sectional circumference of the plug contacts. Nevertheless, it is ensured in an advantageously simple manner that the plug contact inserted into an insulation recess can only connect through its contact element to the wire 903a or 903b which is assigned to this insulation recess. This is achieved in that the two insulation recesses are arranged offset in opposite directions in the transverse direction of the cable within the insulation between the two wires, namely with different mutual distances A and B between the plug contact circumference and the adjacent wire.
  • the protrusion of the contact cutting edges on the plug contacts is dimensioned such that only the thinner layer of insulating material can be severed according to distance B from the contact cutting edges for making contact.
  • This version has the advantage of a particularly simple design and inexpensive manufacturability of the plug contacts.
