Definitions

  • the invention relates to a plug-in element for the electrical connection, in particular of switching devices with busbars or socket elements in distribution systems, preferably in plug-in distributors, according to the preamble of claim 1.
  • Known contact systems have spring-loaded contact tongues or contact webs of known type perpendicular to the plug-in or fastening plane, which contact the current-carrying rails.
  • Such a contact system is known from DE 26 47 573, in which a resilient tongue is folded around a leaf-shaped section and is provided with a helical spring which bears against the inner sides of the tongue and presses it outward, the outer sides of the tongue being under spring pressure Contact the contact surfaces of two parallel cuboid busbars.
  • Such contact systems are relatively sensitive to rotation.
  • Another contact system is a plug-in contact, as is known from EP 0 086 316.
  • This plug-in contact consists of two interacting contact wires, which are held by a leaf spring in a U-profile.
  • the contact area is formed by a center contact tongue of the first contact wire and two side contact tongues of the second contact wire lying around the center contact tongue.
  • Plug-in elements are provided with clip springs which counteract the widening of receiving slots arranged on the plug-in elements.
  • Contact units are also known (DE 31 26 306) which contain a cage-like housing and several pairs of contact members. Each contact member is under the action of a leaf spring. Such contact units have the same disadvantage as the contact system of DE-OS 32 43 064.
  • the individual lamellar webs of the contact strip slotted like a blind form an intermediate layer between two contact surfaces and spring about their longitudinal axis with a certain torsional force when they are pressed together by these contact surfaces, whereby the contact strip acts as an elastic contact layer.
  • a plug-in element (1) for the electrical connection of busbars (L) is known, the plug-in element (1) consisting of a carrier element (3) and elastic contact members (2c) for power transmission, and wherein Plug element consists of a plug shell (3,3a, 3b, 3c) and a contact tab (2). Furthermore, window-like openings are present on the connector shell. Characterized in that the elastic contact members are integrally connected to the contact tab, a secure attachment of the contact members is achieved. However, the favorable contact properties such as the contact lamellae with lamella webs already explained are not achieved.
  • the invention has for its object to provide a plug-in element for the electrical connection with good contact properties, which consists of simple parts, enables inexpensive production and is easy to assemble and are also suitable for the electrical connection of C-shaped busbars or busbars with slot-like tapping zones .
  • the connector shell as a thermoset or thermoplastic and the contact tab as a stamped and bent part. wherein the connector shell and the contact tab are each composed of two identical halves.
  • a further advantageous embodiment results from the features of claims 7 and 8. This results in a robust connection of the two shell halves and the use of a screwless connection makes the plug element particularly easy to assemble.
  • the plug element 1 shown in the drawing is used for the electrical connection of switching devices or the like to a C-shaped busbar or a socket element in distributors.
  • the plug-in element 1 consists of a plug shell 2, composed of two identical plug shell halves 3a, 3b, a contact tab 4 with two identical contact tab halves 5a, 5b and two contact lamellar strips 6a, 6b arranged in mirror image parallel each with two laterally inclined fastening edges 7a, 7b, 7c, 7d.
  • the connector shell halves 3a, 3b are made of a thermoset or thermoplastic and each consist of a cover plate 8a, 8b and a shell wall 9a, 9b formed at a right angle, each of which is divided into two areas 11a, 11b, 12a, 12b, so that in the assembled state of the connector shell 2 window-like openings 10a, 10b are formed.
  • the connector shell halves could equally be made of metal, for example in a die casting process. They are designed so that they can be positively and non-positively connected without additional fasteners.
  • the end regions 12a, 12b have a dovetail-like guide groove 13a, 13b formed perpendicular to the cover plate 8a, 8b, which merges into a likewise dovetail-shaped guide web 14a, 14b, which extends in length to approximately the center of the guide groove 13a, 13b and penetrates the uniformly shaped guide groove 13a, 13b of the other connector shell half 3a, 3b by pushing it into an insertion bevel 22a, 22b and thereby positively connects both connector shell halves 3a, 3b to form a connector shell 1.
  • the contact plate strips 6a, 6b are embedded with their fastening edges 7a, 7b, 7c, 7d, which are laterally inclined inwards, in grooves 15a, 15b, 15c, 15d of the connector shell 2, which are adjacent to the window-like openings 10a, 10b, so that the contact plate strips 6a, 6b fill the window-like openings 10a, 10b area-wide.
  • These grooves 15a, 15b, 15c, 15d have a continuous, semi-arrow-shaped contour running perpendicular to the shell wall 9a, 9b, which prevents insertion (in the direction of the groove (arrow direction A)) or detenting locking (from allow the inside of the connector shell 2 from (arrow direction B)) of the contact plate strips 6a, 6b before the assembly of the connector shell 2.
  • a guide web 23a, 23b is formed on the cover plate 8a, 8b of each connector shell half 3a, 3b in the area of the window-like openings 10a, 10b, which fixes the contact tab halves 5a, 5b in the connector shell 2.
  • the contact tab halves 5a, 5b are designed as a stamped and bent part and are shaped such that they are supported on the guide web 23a, 23b in the region facing the end face 17 of the plug element 1 and contact the inside of the contact plate strips 6a, 6b.
  • the contact tab halves 5a, 5b are brought together flush with the rear side 16 of the connector shell 2, as can be seen in particular in FIG. 3 and for the electrical and mechanical connection of an outgoing line 24 are led out of the connector shell 2 and provided with step-shaped cross-sectional reductions 25, 26, so that an outlet line 24 can be connected to the narrow tab web 27 by means of squeezing technology, the middle tab web 28 forming a stop for the squeezing sleeve 29.
  • each connector shell half 3a, 3b On the cover plates 8a, 8b of each connector shell half 3a, 3b are rectangular grooves 31a, 31b which run transversely to the busbar 30 and serve to fasten the plug element 1 in a receptacle on the back of a distributor insert.
  • the plug element 1 is provided on its end face 17 with an insertion bevel 32, so that the plug element 1 is securely guided into the rail gap 33 when plugged into the C-shaped busbar 30, in order in turn to ensure good electrical contact between the contact lamella strips 6a, 6b and the busbar 30 guarantee.
  • FIG. 3 shows the plug-in element 1 in the inserted state, it being possible to see how the contact lamella strips 6a, 6b form an intermediate layer and current bridge between the contact plate halves 5a, 5b and the C-shaped busbar 30.
