Description

  • The The invention relates to a terminal for electrical Ladder with a stackable in an insulating material, or in block design arranged contact insert, with a bottom-side terminal contact for the electrical connection of a bus bar with a circuit board on the bottom side the busbar curved terminal lugs or pins, wherein the contact insert at least one Steckklemmanschluss for connection for at least has an external conductor to the busbar and the conductor terminal point via a free leg end, one mounted in the busbar U-shaped leaf spring is executed.
  • in the Handling such PCB terminals, it is z.T. for safety reasons prohibited the protective conductor (PE connection) via conductor tracks and solder joints continue to other terminals. The reason for this is that at Occurrence of high currents the conductor tracks or solder joints can be interrupted and the protective function is no longer guaranteed. To this request to fulfill become jumper used in the form of solid metal contacts.
  • It is task of the present invention with a jumper low cost to integrate in a standard terminal, that he requires little space and material and additionally the requirements for safety does justice.
  • These Task is inventively characterized solved, that this Potential of each individual terminal over one in the direction of arrangement extending pin contact is selectively connectable and the pin contact the busbar on the legs of a formed by the busbar Angle of less than 90 ° contacted.
  • With the choice of pin contact as bridging means has succeeded to create a very small, uncomplicated part of the making, what the clamp added Can be used at low cost on the finished terminal to ensure potential replication even for stronger currents. Here are the existing building conditions optimally used to a safe contact point for the bridging to find. This is particularly evident in the location of the pin contact between the wedge-shaped tapered legs of the busbar angle, the at least one safe place for the contact transition between busbar and pin contact allows.
  • A further advantageous embodiment of the invention results from the claims 2 and 3. Thereafter, the pin contact through a hole in the side wall of the insulating material housing passed, wherein the diameter of the hole is such that a floating Ensure storage of the pin contact is. Background for This floating bearing, it is a tolerance compensation for production-related Deviations in the terminals and their seat on the circuit board to accomplish. The hole in this case is so large that the pin contact on can apply any case to one of the legs of the busbar, without the insulating material of the outer wall to be prevented from doing so.
  • From Of particular importance in the context of claim 4, according to which Pin contact over the bearing side leg end of the U-shaped leaf spring against the Busbar is braced. By the pressure of the leaf spring leg becomes with the floating storage a permanent fixation of the Pin contact minimal at a contact point between pin contact and busbar generated. At maximum constellation of all parts he pushes Leaf spring leg the floating pin contact so in through the busbar wedge formed that a contact of the pin contact at two points of contact takes place with the busbar.
  • following is an embodiment of Invention with reference to the drawings described in more detail. Show it:
  • 1 the perspective side view of two queued terminals
  • 2 the aligned contact insert of the terminals after 1
  • 3 an insulating housing of the terminals after 1
  • In 1 are two connected terminals 1 each with a contact insert 2 in each case an insulating material 3 shown. The contact insert 2 consists of an S-shaped bent terminal busbar 4 , from the bottom-side connection lugs 5 are bent for connection to a printed circuit board. In the power rail 4 is a U-shaped leaf spring 6 hooked up and forms together with the power rail 4 a Stecklemmanschluss for an external electrical conductor passing through an insertion 7 in insulating material 3 is pluggable.
  • The U-shaped leaf spring 6 clamps over a free leg end 8th against a deflection 9 the busbar 4 the external conductor. With a second, free bearing side leg end 10 the leaf spring 6 , which is in a rectangular cut 11 the busbar 4 is led, becomes a cylin drischer pin contact 12 used as a support. The pin contact 12 lies in the lower wedge-shaped arch 13 the S-shaped busbar 4 , with the legs of the bow 13 include an angle smaller than 90 °. The insulating housing is on one side by a wall 14 closed, the corresponding formations for receiving the contact insert has. A hole 15 for the implementation of the pin contact 12 is also in the wall 14 contain. For juxtaposing the insulating material housing 3 are located on the open side of the case 3 latching pin 16 ,
  • For mounting the connection terminals 1 On a printed circuit board, these are initially connected to each other via their locking pins 16 connected. Before the connection flags 5 are plugged into the corresponding holes of the circuit board and soldered, the bridge is done via the pin contact 12 , This is a chamfered end of the pin contact 12 under the leg end 10 and inside the bow 13 pushed through, so that in the inserted state, a pressure of the leg end 10 , the leaf spring 6 the pin contact 12 against the interior of the arch 13 suppressed. In the rear part of the insulating material housing 3 penetrates the pin contact 12 the hole 15 in the case back wall 14 which is dimensioned in its diameter so much larger than the pin contact that a floating bearing of the pin contact 12 is balanced and thus a Tolleranzausgleich exists that takes into account the different manufacturing dimensions of the terminals. For the last terminal 1 a series of arbitrarily aligned terminals is for the closure of the insulating material 3 provided an end plate, not shown.
