Definitions

  • the invention relates to a terminal strip for printed circuit boards, in the following abbreviated to terminal block, with the characteristics of the generic term of Claim 1.
  • Terminal blocks of this type generally have an elongated housing, in which several extend in at least one in the longitudinal direction of the housing Row arranged and via housing openings for connection with Mating contacts accessible terminal contact elements are arranged.
  • the individual connection contact elements are certain potentials or Assigned to signals.
  • connection contact elements cross-connected or bridged.
  • One of bridged connection contact elements or the bridge itself is with the Neutral or protective conductor connected.
  • the connection contact elements mentioned are usually not arranged directly next to each other, but are through intermediate, as signal or power supply connections used connector contact elements separated from each other.
  • connection terminals are proposed in which the bridging takes place via the soldering pins, i.e. the Fastening pins with which the terminal block with an electrical circuit board and is mechanically connected.
  • the solder pins are a protective conductor associated terminal contact elements extended so that they in Project the assembly status from the underside of the circuit board.
  • the protruding ones Solder pin sections are then with a cross-connection rail bridged.
  • solder pins for the Protective conductor each 90 ° compared to the solder pins for live or signal-carrying Connection contact elements angled out of the insulating housing led out and connected by a cross bridge.
  • DE 42 28 025 A1 describes a terminal strip in which one Bridging is made with the help of a connecting comb.
  • the connecting comb is with the grid dimensions of the solder pins or the connection contact elements arranged slotted tines. These slotted tines can be plugged onto the solder pins. From this connection comb are optional individual prongs can be removed to certain solder pins or connection contact elements to be excluded from the bridging.
  • connection contact elements in a fixed pitch in the insulating housing are arranged and that for each individual installation-intensive adjustments must be made.
  • connection contact elements at irregular intervals can be arranged side by side without bridging serving cross-connection element to the respective arrangement or to the Distance between the connection contact elements to be connected with a neutral or protective conductor must be adjusted.
  • connection contact elements is in each case with at least one Provide bridge contact, while the other part of the connection contact elements has no bridge contact, the insulating housing at least one outward-open pocket for holding a die Bridge contacts has electrically connecting bridge bar.
  • the Bridge contacts are at any longitudinal position with the Bridge bar contactable. This is in the longitudinal direction of the insulating housing seen, practically at any position a neutral, protective conductor or other Potential can be tapped.
  • the connection contact elements can thus in different distances from each other and also independently of one certain grid dimensions can be arranged in the terminal strip.
  • the bridging is done simply by placing the bridge ledge in the Inserted pocket and with the bridge contacts of about one Connected neutral or protective conductor associated contact elements becomes.
  • the receiving bag is a constructive and manufacturing technology Easy way to attach a bridge bar to the housing.
  • the housing with several, each at different Positionable bridge strips can be fitted.
  • the connection elements can be fixed in different positions in the housing, each in Location of the bridge contact of the connecting element of another bridge bar assigned. Depending on the position of the connection element, it is therefore with a contactable other bridge bar. In this way a distribution of multiple potentials possible simultaneously and independently of each other.
  • a bridge bar the neutral and another Bridge bar is assigned to the protective conductor.
  • Insulating housing with further bridge strips and a signal or a Bridge strips assigned to voltage potential can be equipped.
  • Connection contact element can be arranged in a corresponding position. This can be done at the factory as well as by the customer.
  • the configuration of the terminal strip is therefore very large Adaptability to a wide variety of operating conditions.
  • connection contact element several bridge bars can be assigned. This increases the Possibilities of variation in the distribution of a single potential. If for example according to Claim 4 two bridge contacts on a contact element are arranged, it is possible that a bridge with the factory one bridge contact has been made and other customer contacts Bridges can be made. For example, this would be advantageous if several Insulating housing to be coupled to each other in the longitudinal direction. For electrical cross-connection of the connection contact elements of the the second bridge contact can then be lined up in an insulating housing be used to have the terminal contact elements of an insulating housing to connect those of the other insulating housing with the help of a bridge strip.
  • the insulating housing can be equipped with a total of four bridge rails, the Bridge contacts in a first arrangement of the connection contact element in Insulating housing with a first pair of bridges and in a second arrangement can be contacted with a second pair of bridges.
  • designed terminal block can thus two different potentials, such as one Neutral conductor and a protective conductor, independently distributed or bridged become.
  • connection contact elements only must be manufactured in an embodiment and kept in stock.
  • connection contact element is designed as a flat sheet metal part and transverse to Is arranged in the longitudinal direction in the insulating housing. His two bridge contacts can point to one side in one arrangement, where they have two Bridge strips are contactable. By simply rotating the connection contact element by 180 ° - the axis of rotation is perpendicular to the plane spanned by the transverse and longitudinal direction of the insulating housing - the bridge contacts can be arranged on the opposite side become. There you can contact two other bridge strips.
  • bridge contacts are designed as clamping contacts.
  • the Connection with a bridge bar can then be done simply by that the bridge bar is pressed into the terminal contact (claims 7 and 8).
  • the housing is advantageously composed of several insulating housings connected together at the end. It is advantageous if the interconnected insulating housing is in terms of Arrangement or positioning of the receiving pockets correspond to each other and the pockets in the facing or in the assembled state abutting end faces of the insulating housing. In this way it is ensured that the associated or corresponding Recording pockets are aligned in a line. Two or too a plurality of interconnected insulating housings can then easily be created can be electrically connected to each other by a bridge bar. The In this case, bridge strips are expediently longer than an insulating housing. It can then optionally two or more with a single bridge bar or insulating housing can be electrically connected to one another. Through the Measure according to claim 12 is a certain protection against accidental Bridging the bridge bar and also a protection against accidental contact.
