Definitions

  • the present invention relates to a printed circuit board relay, which has at least two connection pins for the energization of the relay coil and at least two plug-in lugs for the energization of a load circuit.
  • printed circuit board relays are frequently used since, in contrast to plug-in relays, such printed circuit board relays are specially designed so that they can be placed on a printed circuit board of the device or controller.
  • On the circuit board there are both tracks for the control circuit as well as for the load circuit of the relay.
  • the conductor tracks of the control circuit serve to control the relay coil, whereas the tracks of the load circuit are used to provide a switched by the relay load voltage.
  • these tracks must be made relatively wide, which causes the tracks take up a lot of space on the board to complete. Under certain circumstances, so much space on the circuit board occupied by the tracks of the load circuit, that for other tracks on the circuit board is no longer enough space available.
  • the invention has for its object to provide a circuit board relay, which does not have the disadvantages described above.
  • connection pins for the energization of the relay coil on a different side of the relay housing are as the terminal lugs for the energization of the load circuit.
  • connection pins for the energization of the relay coil and the terminal lugs for the energization of the load circuit are on different sides of the relay housing, it is not necessary to provide the power supply for the load circuit located on the circuit board tracks. Rather, for example, a load current side cable set can be hardwired directly to the terminal lugs for the energization of the load circuit, so that the limited space of a circuit board is not taken by traces for powering the load circuit.
  • the plug-in flags can be designed in accordance with an embodiment according to stiff to be insensitive to mechanical effects in a plug connection process.
  • the plug-in lugs can have a higher rigidity and in particular a higher critical buckling load than the connection pins.
  • the rigidity of the connection pins can in principle be kept relatively low, since they are soldered in the usual way on the circuit board and thus are exposed only to low mechanical stresses.
  • connection pins for the energization of the relay coil may protrude from a first side of the relay housing, whereas the terminal lugs for the power supply of the load circuit protrude from one side of the relay housing opposite the first relay housing side.
  • the connection pins can be located on the underside of the relay housing, which comes to lie opposite the circuit board, whereas the terminal lugs are arranged on the top of the relay housing.
  • the printed circuit board relays according to the invention can first be soldered to a printed circuit board, so that subsequently the printed circuit board as a whole can be gripped with the printed circuit board relays thereon, to plug the terminal lugs of each circuit board relay with only a single mating process in an electrical connection carrier on which in turn the individual cables of a cable set are connected.
  • the circuit board with the individual board relay located thereon can thus be considered as a whole as a plug body with a plurality of protruding plug flags as a whole, which can be plugged together into an electrical connection carrier.
  • connection pins for the energization of the relay coil may protrude from a first side of the relay housing, whereas in this embodiment the terminal lugs for the energization of the load circuit protrude from a side of the relay housing adjacent to the first relay housing side, so that the connection pins and the terminal lugs are vertical aligned with each other.
  • This embodiment is particularly useful if, for example, the space in a housing for routing above the circuit board is limited, since then the respective cables of the harness can be connected laterally to the PCB relay, so above the PCB relay no additional space is needed.
  • the terminal pins can protrude from a first side of the relay housing, whereas the terminal lugs beflanken a side adjacent to the first relay housing side of the relay housing and thereby survive beyond the first relay housing side opposite side of the relay housing.
  • This embodiment is particularly suitable if, due to the internal structure of the PCB relay, the contacts for the terminal lugs although laterally from the relay housing must be led out, on the other hand, however, at the same time would like to take advantage of the embodiment described above, in which protrude the tabs of the first relay housing side opposite side of the relay housing.
  • the PCB relay can have at least two additional connection pins, which are electrically coupled to the terminal lugs for the energization of a load circuit.
  • these connection pins which are coupled to the terminal lugs for the energization of the load circuit, point in the same direction and protrude on the same side as the connection pins for energizing the relay coil of the relay housing to be soldered on the circuit board and monitored via the same for diagnostic purposes to be able to.
  • connection pins are electrically coupled to the terminal lugs for the energization of the load circuit, the proper function of the invention can be achieved via these connection pins PCB relays are monitored via the PCB.
  • potential measurements in the load circuit can be made via the aforementioned connection pins, from which it is possible to draw appropriate conclusions about the proper functioning of the printed circuit board relay and, in particular, on the switching function of the relay coil.
  • connection pins for the energization of the relay coil and possibly also coupled to the terminal lugs for the load circuit terminal pins may also be formed as plug contacts, which have sufficient rigidity, in order not to be bent or bent during a plugging operation in socket openings formed in the printed circuit board.
  • circuit board relay 10 has a housing 20, which has a cuboid shape in the embodiment shown here.
  • the housing 20 serves to receive the individual switching components of the printed circuit board relay 10 such as a relay coil, an operable by the relay coil switching armature as well as several operable by the switching armature normally open contacts.
  • the individual switching components of the printed circuit board relay 10 such as a relay coil, an operable by the relay coil switching armature as well as several operable by the switching armature normally open contacts.
  • these known per se switching components of the PCB relay 10 in the Fig. 1 but not shown.
  • the printed circuit board relay 10 also has two pin-shaped connection pins 12, which can be soldered directly on a printed circuit board in contact with associated conductor tracks.
  • the connection pins 12 are coupled to the relay coil, not shown here, within the housing 20 so that a voltage can be applied across the printed circuit board and the connection pins 12 to the relay coil for switching purposes.
  • the printed circuit board relay 10 according to the invention has three plug-in lugs 16, over which alternately two load circuits can be switched as a result of the operation of the relay coil.
  • connection pins 12 are for the energization of the relay coil according to the invention on a different side of the relay housing 20 as the terminal lugs 16 for the energization the load circuits.
  • the connection pins 12 are for the energization of the relay coil from a first side of the relay housing 20, which is also referred to as the housing bottom, whereas the terminal lugs 16 protrude for energizing the load circuits of one of the first relay housing side opposite the second side of the housing 20, which here also referred to as housing top.
  • connection pins 12 and the terminal lugs 16 on different sides of the housing 20 of the PCB relay 10 can be achieved that a load current side cable set can be hard wired directly to the terminal lugs 16 for the energization of the individual load circuits.
  • a load current side cable set can be hard wired directly to the terminal lugs 16 for the energization of the individual load circuits.
  • the plug-in lugs 16 have a significantly greater width than the connection pins 12 serving to energize the relay coil.
  • the connection pins 16 acquire a significantly higher rigidity and in particular a higher critical buckling load than the connection pins 12, so that the plug-in lugs 16 can be connected to the individual cables of a cable set or to a carrier having a plurality of socket openings for coupling purposes by means of a plug connection process. Due to the higher stiffness of the terminal lugs 16 is thereby ensured that the terminal lugs 16 are not in such a plug connection process or buckle or otherwise bent.
  • the terminal lugs 16 can also protrude from a side surface of the relay housing 20, so that the terminal pins 12 and the terminal lugs perpendicular to each other.
  • FIG. 1 Another arrangement possibility of the terminal lugs on the relay housing 20 is in the Fig. 1 explained with reference to the reference numeral 18 pin flag.
  • this tab 18 branches off from a side surface of the relay housing 20 and is angled in the immediate vicinity of the housing 20 such that it flanks the side surface of the relay housing 20 to over the top of the relay housing 20.
  • the Fig. 1 only one plug-in lug 18 is shown, which protrudes from a side surface of the relay housing 20 and projects beyond the top of the relay housing 20. In a corresponding manner, however, several plug-in lugs can be arranged and formed.
  • plug-in lugs 16, 18 protrude from the upper side or from a side surface of the relay housing 20, and overhang them over the upper side of the relay housing 20, all these arrangement possibilities of the plug-in contact lugs 16, 18 have the common feature that the plug-in lugs 16, 18 are freely accessible to be wired directly to a load current side harness.
  • the circuit board relay 10 has further connection pins 14, which are electrically coupled to the terminal lugs 16, 18 in the interior of the housing 20, as indicated by the current paths indicated by the reference numerals 22.
  • the connection pins 14 have in the same direction as the connection pins 12 for the energization of the relay coil and are also from the bottom of the relay housing 20 from.
  • the connection pins 14 can thus be soldered in the same way as the connection pins 12 with corresponding conductor tracks on the circuit board, so that the proper functioning of the circuit board relay 10 can be monitored by means of monitoring devices arranged on a circuit board via the connection pins 14.
  • the printed circuit board relay 10 thus combines the advantages of a conventional PCB relay with the advantages of a plug-in relay, on the one hand, the plug-in lugs 16, 18 are formed freely accessible and arranged to connect directly load-side cable can, and on the other hand monitoring the proper operation of the PCB relay 10 is ensured via the connection pins 14 via a printed circuit board.
  • these interconnects which couple a plurality of circuit board relays, may be conductively connected to plugs or sockets arranged or formed on the circuit board, so that a contact with a cable set can be made directly via the interconnects in question.
