Definitions

  • the present invention relates to a plug bridge of a safety plug according to the preamble of patent claim 1.
  • Plug bridges of this type are known and they have also proven and become generally accepted with regard to the operational safety and manageability of the connected electrical devices. With regard to their electrical safety, the key point of the plug bridges mentioned is, in particular, that the connectors to be connected to the connecting sockets, i.e. to be crimped or crimped stranded ends of the conductors (current conductor, protective conductor) during assembly and subsequent finishing are so securely "caught and held" that the risk of laterally protruding or even protruding individual wires of the stranded ends is practically eliminated.
  • a connector bridge is known, in which any protruding individual wires are intercepted by the special shape or configuration of a protective cap to be placed on the connector bridge.
  • DE-OS 38 07 716 a connector bridge with an insertion funnel for the protective conductor and insertion funnels for the current conductor is known, wherein the shaped elements forming the insertion funnels each lie opposite the connection sockets or rest on their free end faces. Further developments of these last-mentioned plug bridges are published in DE-OS 39 11 315, DE-OS 39 11 316 and DE-OS 39 15 852. The focus is always on the way of constructive design and the assignment of the insertion funnels. Another variant is the subject of DE-GM 87 16 567. This concept is based on individual hat elements which are positively attached to the connecting sockets and are bent inwards when the plug bridge is encapsulated; the hat elements mentioned are optionally also connected in pairs for use in connection with a plurality of connection sockets.
  • the known plug bridges are either conceptually or structurally complex, or they are still associated with a risk in terms of electrical safety, as individual wires can still be pressed laterally between the insertion funnels and the connecting sockets and protrude when the strand ends are inserted.
  • the object underlying the present invention is to provide a connector bridge of the generic type, in which a secure capture of the stranded wires is ensured with a simple center.
  • the insertion funnel on its side facing the connection socket or the plug bridge has a hat-shaped projection over the connection socket up to the plug bridge Insulating sleeve is assigned.
  • These receptacles cooperate with the insertion funnels in such a way that, when the strand ends are inserted, approximately bent individual wires are intercepted in the annular space between the connection socket and the receptacle.
  • the insertion funnel and the insulating sleeve form a one-piece unit.
  • Further refinements and developments of the plug bridge are the subject of subclaims 3 to 6.
  • the units consisting of insertion funnel and insulating sleeve can also be connected to one another in such a way that, if necessary, a one-piece molded part can be placed on the plug bridge and so at the same time the majority of the connecting sockets are covered with an insertion funnel and an insulating sleeve.
  • a cut in the axial plane of a connector 1 connector bridge 2 is shown, which is generally made of hard elastic plastic as a U-shaped molded part.
  • the plug bridge 2 is injection molded in a corresponding injection mold around the connecting socket 1 or a contact pin 3 connecting coaxially to the connecting socket 1, knurling 4 being used to secure rotation and tension at the transition area from the connecting socket 2 to the contact pin 3 (or vice versa) and circumferential edges are provided.
  • the contact pin 3 is on one side of the connector bridge 2; Diametrically to this, the connector socket 1 projects from the second side of the plug bridge 2.
  • the latter has an inner cylinder 5 which is open from the free end face 4 and extends approximately into the region of the plug bridge 2.
  • the plug bridge 2 is completed with the connection socket 1 before the final shaping or final production of the protective contact plug insofar as a stranded wire, stripped to a predetermined length, of a consumer cable leading to an electrical device is inserted into the inner cylinder 5 of the connection socket 1 and by crimping (crimping ) is fixed.
  • the connecting socket 1 is assigned an insertion funnel 6, via the conical through-hole 7 of which a secure insertion of the stripped stranded conductor end should first be ensured.
  • connection socket 1 there is - as long as the insertion funnel 6 does not rest bluntly on the connection socket 1 - there is still the risk that when inserting the stranded conductor at the end face of the connection socket 1 individual wires are bent and individual wires can protrude laterally.
  • an insulating sleeve 8 which is preferably manufactured or connected in one piece with the insertion funnel 6, is provided coaxially to the conical through-bore 7 on the side of the insertion funnel 6 opposite the connection socket 1, which is connected to the plug bridge 2 or to a circumferential ring of the connection socket 1 gets up. It is irrelevant whether - as shown in the drawing - the insulating sleeve 8 dips into the connector bridge 2 or whether it terminates with the level of the connector bridge 2.
  • the length of the insulating sleeve 8 and the length of the cylindrical part of the connector 2 projecting freely relative to the plug bridge 2 are preferably - within the scope of the manufacturing tolerances - coordinated with one another such that after assembly of the unit consisting of the insertion funnel 6 and the insulating sleeve 8 or corresponding molded part, the underside of the insertion funnel 6 does not rest on the end face of the connecting socket 1; the insulating sleeve 8 is also dimensioned so that a perfect pinch (crimp connection) of the stranded conductor remains guaranteed.
  • the leading part during assembly is provided Chamfer the inner edge of the insulating sleeve 8 (see reference number 9).
  • the front inner edge of the conical shape see reference number 10
  • the initial diameter of the cone of the insertion funnel 6 and the front-side cone diameter or outlet radius of the connecting socket 1 are coordinated with one another in such a way that the latter offers a larger opening at the front than the output cone of the insertion funnel 6.
  • a plug bridge 2 including the feeding and insertion of a stranded wire end in a connection socket 1, it is ensured - apart from the last-mentioned assembly or handling simplifications - that, for example on the free end face of the connection socket 1, individual wires of the stranded conductor kinking on the inner wall of the Insulating sleeve 8 bent again and steered into the annular space between the connecting socket 1 and the insulating sleeve 8. This absolutely ensures that no individual wires of the stranded wire can protrude laterally.
  • earthing contact plugs have three connecting lines, and one earthing conductor and two current conductors (phase conductors).
  • the corresponding plug bridge accordingly has a connection socket for the protective conductor and two connection sockets for the current conductors, whereby - with regard to the assembly - when inserting the stripped stranded wire ends, there is the same risk of kinking and laterally protruding individual wires.
  • the present invention can also be implemented in that, in order to simplify assembly and storage, a uniform molded part is also created for the two current conductors or the current conductors and the protective conductor.
