Definitions

  • connection block for e.g. a cable termination unit according to the preamble of claim 1.
  • connection block is known for example from EP-A-0 200 883.
  • This comprises an insulating body, which consists of a lower part and an upper part, in which receiving recesses are formed.
  • Connection contacts are arranged in the receiving recesses, each having contact slots.
  • the connection block comprises disconnection devices in the form of cutting knives, one of which is assigned to a connection contact and is used to cut excess lengths of the wires to be connected.
  • connection block constructed in this way has proven itself in practice, it is in need of improvement insofar as its construction is still relatively complex. Because the cutting knives are stored separately in the insulating body and due to the special design of the connection contacts and their arrangement with respect to the cutting knives, a specially designed so-called two-legged or multi-legged wiring tool is required to contact the wires to be connected in the terminal block. This wiring tool has a special construction, so that its manufacturing costs are not insignificant.
  • connection block of the type specified in the preamble of claim 1 the construction of which is simplified and which enables the use of a commercially available tool as a wiring tool.
  • connection contacts and the disconnection or clamping devices first simplifies the connection block, since no separate receiving recesses for the disconnection devices are required.
  • connection contacts and the disconnection or clamping devices can be produced in one operation, which initially reduces the manufacturing costs and further reduces the assembly costs, since in the course of arranging the connection contacts, the disconnection or clamping devices are naturally simultaneously inserted into the connection block.
  • connection block according to the invention has the advantage that, for example, a screwdriver or a similarly designed plunger can be used as a wiring tool, for which purpose corresponding guides for such a one-leg wiring tool are provided on the connection block and / or on the connection contact.
  • the guides and the connection contact elastically springing away in front of the screwdriver, the screwdriver or the one-legged wiring tool can be guided along the contact by the operator, regardless of his skill, in such a way that the wire is connected and possibly cut off.
  • the spring-loaded connection contact or the corresponding part finds a limited clearance in the insulating body, which prevents deformation of the legs or the entire connection contact.
  • connection block according to the invention is designed such that, in the course of pushing in the wire to be connected by means of a one-legged wiring tool, both the contacting of the wire not previously stripped and, if appropriate, a protruding wire length are cut off.
  • a clamp-like design of the disconnection or clamping device and the connection contact results in the advantage of a particularly simple production possibility that is inexpensive.
  • the resilient arrangement of the disconnection or clamping device on the connecting contact advantageously ensures that the disconnecting or clamping device or the contact is deflected in the course of contacting the wire to be connected, as a result of which a tensile force is exerted on the pinched wire and, for example, notched in the separating device which, in the corresponding embodiments, ultimately leads to the excess wire length being cut off.
  • a particularly advantageous design for the separating device is a knife slot in one leg of the clip, since this represents a simple design of the separating device.
  • the knife slot and the contact slot are arranged so that they open upwards in the installed state so that the unit formed from the disconnecting device and the connecting contact is easily accessible.
  • the lower end region of the separation device or the knife slot is arranged higher than the lower end region of the contact slot, so that sufficient pulling force can be applied to separate the protruding wire length after a relatively short push-in path of the wiring tool.
  • a particularly easy and exact separation is achieved if the knife slot is tapered.
  • the guide surface for the one-leg wiring tool can be arranged on the disconnection device, the guide surface pointing to the connection contact.
  • an insertion area can be connected upwards to the knife slot and the contact slot, which widens conically.
  • the receiving recess of the insulating body has a contact surface to which the separating or clamping device is attached in the course of contacting and and disconnecting or clamping the wire after passing through a certain evasion movement. This stabilizes the clip and prevents it from undesirably buckling when making contact and disconnection or clamping. This is particularly important and advantageous when using a one-legged wiring tool, since this itself cannot have any supporting effect on the connection contact or the disconnection or clamping device.
  • a clamping device can e.g. be provided in the form of a clamping slot.
  • a resilient clamping and contact clip which has the clamping slot on the one hand and the contact slot on the other.
  • the embodiment with a clamping slot also has the particular advantage that it also acts as a strain relief slot for the contacted wire, so that the tensile forces and vibrations exerted on the wire during operation do not impair the contacting.
  • the guide surface for the wiring tool is arranged on a side of the connection contact pointing to an adjacent wall of the connection block.
  • the opposite wall of the insulating body of the terminal block has a surface that together with the guide surface of the connection contact in the installed state delimits a tapered receiving chamber.
  • the dimensions of the chamber are adapted to the one-legged wiring tool to be used in such a way that, on the one hand, the operator can easily insert the one-legged wiring tool, ie the screwdriver, between the bracket and the insulating body, regardless of their skill, and that, on the other hand, the bracket dodges elastically, but after the evasion finds stabilization on the insulating body.
  • the conically tapering wall of the insulating body can be replaced by a further clamping leg, which is integrally connected to the clamping and contacting unit and can also have an edge that further clamps the protruding wire length facilitated.
  • connection block As a particularly simple embodiment for the wiring tool, which can be used due to the special design of the connection block according to the invention, a commercially available screwdriver or other conically tapering pressure plunger is suitable. This results in the particular advantage that no costs have to be expended for a specially designed wiring tool, so that the contacting and disconnecting process can be carried out at any time with commonly used screwdrivers.
  • connection block according to the invention In addition, it should be pointed out that, for reasons of simplification, only parts of the connection block according to the invention are shown. In practical terms, this consists of a plurality of parts to be described below. To complete the description, reference is therefore expressly made to the disclosure of EP-A-0 200 883, which explains in detail all the parts which are also used in the connection block according to the invention, with differences of course due to the design according to the invention, which follows is described in detail.

  • the insulating body 2 is provided with an extension 5 which has a feed-through recess 6. Through the feed-through recess 6, wires 7 to be connected can be passed through, as can be seen in detail from FIGS. 1 and 2.
  • connection block 1 has a connection contact 8 and a disconnection device 9.
  • the connection contact 8 and the disconnecting device 9 are formed in one piece and together form an elastic spring clip 10.
  • the respective clamp 10 is arranged in the associated receiving recess 3 of the insulating body 2.
  • the receiving recess 3 has in particular a boundary wall 11, as shown in FIGS. 1 and 2, on the left-hand side, essentially perpendicular to the bottom surface of the insulating body 2, a bottom wall 12 adjoining it at right angles and a bottom wall 12 adjoining it at right angles Wall piece 13 on.
  • the wall piece 13 merges at an obtuse angle upwards into a wall area 14 which forms a contact surface 15 pointing into the receiving recess 3.
  • the function of this contact surface 15 will be described in more detail below.
  • connection contact 8 has a rectilinearly extending, flat leg 18, which has a contact slot 19 in its upper region is provided. This contact slot 19 is used for contact-free contacting of the wire 7.
  • the leg 18 is integrally connected to a U-shaped connecting piece 20.
  • the connector 20 is also integrally connected at its other end to a flat leg part 21 which extends parallel to the leg 18 and which, like the parts still to be mentioned, is to be counted among the separating device 9.

  • an intermediate section 29 extending parallel to the leg 18 is arranged between the leg part 28 and the bent region 22.
  • This section 29 has on its side facing the leg 18 a guide surface 30, which therefore on the Separating device 9 is arranged.
  • This guide surface 30 is used to guide a one-legged wiring tool 31, which can be, for example, a conventional screwdriver with tapered side surfaces.
  • a wiring tool 31 is also shown schematically in a slightly simplified manner in FIGS. 1 and 2.

  • the wiring tool 31 If the wire 7 is to be contacted, the wiring tool 31 is moved in the direction of the double arrow 32 down towards the bottom of the receiving recess 3. As is clear from FIG. 2, the wiring tool 31 presses the wire 7 with its left-hand end into the contact slot 19, the insulation of the wire being severed and thus contact being made. The wiring tool 31 rests with its corresponding surface on the guide surface 30 of the separating device 9. Due to the conical design of the tip of the wiring tool 31, the bent region 22, which is connected to the leg 18 in a resilient manner via the leg part 21 and the connecting piece 20, is deflected and is supported on the contact surface 15.
  • the wire end 34 of the contacted area of the wire 7, which end extends into the receiving recess 3, is bent over and thus lies against the inside of the leg 18. This improves the hold of the wire 7 in the contact slot 19, so that the contact is maintained even when a tensile load is applied.
  • the wiring tool 31 is pulled upward in the direction of the double arrow 32 from the receiving recess 3, after which the disconnecting device 9 springs back into its position shown in FIG. 1.

  • the excess length is cut off at the shear strip 71 because the underneath the insertion opening 58 in the insulating body 2 ′′′ formed V-shaped chamber 86 only offers space for the one-leg wiring tool in the form of a screwdriver 87, but not for the wire.
  • the illustration in FIG. 9 shows that the design of the chamber 86 is selected so that it fits exactly with the screwdriver 87, so that the desired function is ensured.
  • the separating device from the shear strip 71 and the stop strip 70 is formed, which are also integrally connected to the connection contact 8 Kunststoff to form the clamp 10 'and enable the use of a simple screwdriver as a wiring tool.
  • the additional disconnection option further expands the adaptation options of the embodiment according to FIGS. 9 and 10. Otherwise, this embodiment also has all advantages that have been explained above in connection with the other embodiments.
