Definitions

  • the present invention relates to the free connectors equipped with cable clamping devices, such connectors normally used as trailing sockets and plugs.
  • the aim of the cable clamping device is to clamp the cable to the plug or socket, preventing it from being unintentionally extracted owing to traction being exercised on it, either as the result of a mistake in operation or in the case of an accident.
  • Connectors including cable clamping devices are known from e.g. DE-A-2433347
  • the cable clamping devices prevent the connecting terminals from being subjected to traction and prevent the cable itself from being disconnected from the terminal plate of the connector, thereby causing serious trouble.
  • Cable clamping devices made of plastic material are well-known where two tongues of the same material extend from the periphery of the terminal plate and, at the opposite end with respect to the terminal plate, broaden into two coupling brackets, inside which the electric cable is inserted. After the cable is inserted, the clamps are locked one against the other by means of a pair of screws, with their respective nuts, thus carrying out fixing of the cable inserted between them.
  • the device described has some disadvantages, such as:
  • Aim of the present invention is to produce a clamping device for trailing sockets and plugs which is able to avoid the difficulties mentioned above, that is one which facilitates cable connections, allows an identical terminal plate to be contructed for stationarily mounted and trailing sockets and plugs, and facilitates installation.
  • an electrical connector according to Claim 1 comprising a terminal plate and a clamping device which are integral with said terminal plate during use, in which said clamping device and said terminal plate consist of two separate elements, each equipped with a reciprocal engaging means, said connector characterized in that said engaging means consists, as regards the clamping device, of a pair of arms integral with said device, the arms being integral with just one of the two coupling brackets suitable for receiving the electric cable between them, at least one of the two arms having an enlarged head at its free end, capable of locking into a hole provided on the terminal plate.
  • One arm can also be equipped with a seat capable of being received into a peripheral slot provided on the terminal plate, provision being made in this case for the rotation of the engaging means of the other arm with respect to the terminal plate.
  • the seat ends in a collar which prevents the arm from escaping.
  • the clamping of the cable into the clamping device is performed preferably by inserting the jagged wings of one bracket inside the corresponding openings of the other bracket, one wall of which is defined by a tongue suitable of cooperating with said jagged wings.
  • the connection is detachable by operating upon resilient wings which allow said tongue to disengage from the jagged wings.
  • the two brackets are joined together during moulding by a metal strip.
  • the clamping device comprises a clamping bracket 3 and a bracket 1 equipped with two equal symmetrical wings 2a and 2b.
  • the two brackets 1 and 3 are joined together by means of a narrow strip 4.
  • the wings 2a and 2b of the bracket 1 are jagged on their inner side.
  • the bracket 3 consists of a central part 5 suitable for receiving the cable, and of two equal openings 6a and 6b, inside which two elastic tongues 7a and 7b are provided respectively, which are equal and symmetrical and suitable for engaging with the jagging teeth of the wings 2a and 2b.
  • the tongues 7a and 7b are each provided with a wing 7c and 7d, respectively, which is resilient and projects in a perpendicular direction with respect to the tongues 7a and 7b themselves.
  • the central part 5 of the bracket 3 in which the electric cable is housed is equipped with four projecting elements 8a, 8b 8c and 8d, having a conical shape with a rounded top, to ensure a better grip on the cable.
  • the arm 9 ends in a head 12 above which an abutment 12a is provided.
  • the arm is also equipped with a collar 11 for acting as a further ledge which can serve as a stop during wiring.
  • the arm 10 ends in a seat 13 comprised between two collars, one of them, 14, located at the end and the other, 13a, more internally.
  • the terminal plate 21, to which the trailing socket, plug or such is connected is equipped, as is already known, with holes 24a, 24b, and 24c respectively, into which the wires will be inserted to carry out the connection.
  • the terminal plate is further equipped with fixing holes 22a and 22b and possibly with a notch 23.
  • the terminal plate 21 is equipped with a further throughhole 25, along its periphery.
  • This hole is internally provided with four equal projections 26a, 26b, 26c and 26d, which extend into the plug- or socket housing.
  • the configuration of the walls of the hole 25 can be better seen in figure 3, where two of the projections, in particular 26c and 26d, are to be seen.
  • the arm 9 (see figure 1) of the clamping device is positioned over the hole 25; the foremost part of the arm 9 with its hemispherical head 12 is then inserted into the hole 25.
  • the heads 12 slides within the projections 26a, 26b, 26c and 26d, and finally protrudes from the hole 25.
  • the projections 26a, 26b, 26c and 26d rest on the lower base of the head 12, where the diameter of the arm 9 is narrower and prevents the arm 9 from being extracted from the terminal board 21.
  • the other arm 10 of the bracket 3 is made to rotate relatively to the arm 9 and positioned in correspondence with the slot 27. Then the arm 10 is pressed into the slot 27, slides along it and comes to abut against the semicircular rounded form at the terminal end of the slot.
  • bracket 3 is near to the cable which, in order to be clamped, has only to be gripped by the other bracket 1 whose wings 2a, 2b, are made to penetrate the openings 6a and 6b.
  • bracket 1 If it is desired to disconnect bracket 1 from bracket 3, in order to release the cable, it is sufficient to slightly push on the wings 7c and 7d, by hand or by means of a tool, bringing said wings nearer to each other. In this way, the tongues 7a and 7b disengage from the jagging teeth of the wings 2a and 2b, which can be withdrawn from openings 6a and 6b.
