Definitions

  • the invention relates to connecting devices to which an electrical conductor can be connected. Furthermore, the invention relates to low-voltage switching devices.
  • Low-voltage switching devices comprise contact positions, such as spring-force clamp terminals or screw terminals, to which electrical conductors can be connected.
  • the contact positions can then be used for electrical contacting of devices, such as load feeders or reversing contact assemblies.
  • the electrical connecting of devices via spring-force clamp terminals can be carried out by using wires as shown in Figure 1 where contactors of a contactor group have been so interconnected.
  • DE 102 36 790 C1 discloses a switching device that has an insulating housing, each switch pole having incoming and outgoing contacts provided with respective terminals for connection with an external electrical lead, at least one of the contacts having a second terminal for connection with a second electrical conductor, positioned between its opposite ends, respectively provided with the first external electrical lead terminal and a stationary switch contact.
  • Each second terminal can be provided by an opening for reception of an electrical conductor pin contact.
  • connection block for electrical devices in published patent application EP 1 026 782 A1 , where a connection block is used to provide a link between sockets on two adjacent appliances.
  • the connection assembly comprises two items of electrical apparatus placed side by side, with sockets formed in adjacent positions on the same sides of the items.
  • a connector plug with an insulating body and terminal pins is engaged in the side of the two items into the tool opening of a spring-force clamp of the CAGE CLAMP reigstered type (registered trademark of WAGO Kunststofftechnik GmbH & Co. KG).
  • the spring-force clamp cannot provide a good mechanical contact to a first electrical conductor together with a second electrical conductor, since the second electrical conductor would jam the tool opening and thus prevents the spring-force clamp from clamping the first electrical conductor.
  • a first objective of the invention is to bring out a connecting device that can be used to contact a first and a second electrical connector with one spring-force clamp connector.
  • a connecting device comprising a housing comprising an opening for receiving an electrical conductor and a tool opening, and at least one spring-force clamp connector in said housing, the spring-force clamp connector comprising a bent leaf spring and a responsive counterpart wall, the bending of the leaf spring forming a first leg and a second leg, said leaf spring adapted i) to clamp an electrical conductor between said first leg and said counterpart wall and ii) to release said electrical conductor upon being pressed through said tool opening by a pressing tool, there is provided a further opening in the housing for receiving a second electrical conductor, and the leaf spring is adapted, in response to receiving a second electrical conductor through said further opening, to allow bending of said second leg and so to clamp said second electrical conductor between said second leg and a second counterpart wall.
  • a second objective of the invention is to provide a low-voltage switching device, especially a contactor, a circuit breaker, an overload relay, or a motor starter, that would be easily connectable to another low-voltage switching device via a link module, and that would enable easy connecting of further electrical conductors.
  • This objective can be achieved as set out in claim 7, by using a plurality of connecting devices according to the first objective of the invention in said low-voltage switching device connected to switch poles of said low-voltage switching device.
  • the design of the connecting device may be easier, since then there is no support extra support needed for the leaf spring, but it can be simply placed in an appropriate slot.
  • said counterpart wall and said second counterpart wall comprise conductive material, the electrical current does not need to be passed through the leaf spring. Depending on the application and the amount of electrical current to be transferred, this may be useful since the leaf spring does not need to be used as current transport medium, but the counterpart walls are used as the main current transport media. Especially in the case of low-voltage switching applications, this may be very important because the losses in the transport medium are thus easier to reduce, for example.
  • the first electrical conductor can be used for measurement purposes, whereas the second electrical conductor can be used to connect the connecting device to a current supply or to another connecting device, or vice versa. If said counterpart wall and said second counterpart wall are furthermore integrally formed, the first and the second electrical conductor can be connected to an essentially same potential at both connecting points.
  • FIG. 2 shows a section of a connecting device 30 according to the first objective of the invention.
  • the connecting device 30 comprises a housing 32 comprising an opening 38 for receiving an electrical conductor, a tool opening 37, and a further opening 39 for receiving a second electrical conductor.
  • the connecting devi,ce 30 further comprises at least one spring-force clamp connector located in the housing 32 and comprising a bent leaf spring S and a responsive counterpart wall 31, the bending of the leaf spring S forming a first leg 33 and a second leg 36.
  • the spring-force clamp connector is a push-in clamp.
  • the leaf spring S is adapted to clamp an electrical conductor that has been introduced to the spring-force clamp connector through the opening 38 in between said first leg 33 and said counterpart wall 31.
  • the electrical conductor can be released by pressing the first leg 33 with a pressing tool, such as a screw driver, through the tool opening 37.
  • the pressing tool bends the first leg 33 which then releases the electrical conductor.
  • the leaf spring S is adapted to, in response to receiving a second electrical conductor 40, to allow bending of the second leg 36 and so to clamp said second electrical conductor 40 between the second leg 36 and a second counterpart wall 31.
  • a part 41 of the second leg 36 transfers the spring force caused by the leaf spring S to the electronic conductor 40 and presses it against the counterpart wall 31.
  • the bent leaf spring S is preferably shaped to substantially have the shape of an U.
  • the counterpart wall 31 and the second counterpart wall preferably comprise conductive material, and they are preferably electrically connected to each other.
  • the counterpart wall 31 and said second counterpart wall 31 are integrally formed, so that an element comprising both preferably consists of one part only.
  • the electrical conductor 40 may have latches or be bent, to provide a latch between the second leg 36 of the leaf spring S which is preferably shaped to match with the latches or bending of the electrical conductor 40.
  • the shape of the second leg 36, especially around the force transfer part 41, is preferably bent to increase pressure exerted on the electrical conductor 40. Furthermore, if the electrical conductor 40 is bent appropriately, the bending of the second leg 36 may match to the bending of the electrical conductor 40 in a form-locking manner, thereby making removing of the electrical conductor 40 by pulling more difficult.
  • the housing 32 preferably consists of electrically insulating material.
  • the housing 32 of connecting device 30 comprising a push-in clamp 32 has a further opening 39 in addition to the conductor opening 38 and the tool opening 37.
  • the further opening 39 is preferably so placed that a second conductor 40 can be pushed in. In this manner, also the rear side of the push-in clamp can be used as the plug-in position.
  • Figure 4 shows a group of low-voltage switching devices 51, 53 comprising connecting devices 30.
  • the low-voltage switching devices 51, 53 in Figure 4 have been connected to each other using a link module 50.
  • a low-voltage switching device 51, 53 may comprise a plurality of connecting devices 30 according to any one of the preceding claims; at the input side (as in low-voltage switching device 51 that is preferably a contactor), at the output side (as in low-voltage switching device 53 that is preferably a circuit breaker) or both.
  • the low-voltage switching devices 51, 53 may also comprise spring-force clamps 55 or screw terminals, but preferably only on the side on which there are no connecting devices 30 according to the invention.
  • the connecting devices 30 are preferably arranged on the input and/or output side of the low-voltage switching device 51, 53, and they are preferably provided for each of the poles for receiving the phases of a three-phase current.
  • the housing 32 comprises now preferably the housing of the low-voltage switching device 51, 53.
  • the link module 50 can be used to connect two low-voltage switching devices 51, 53 to each other both mechanically and electrically.
  • the link module 50 comprises electric conductors 40 for connecting both to low-voltage switching device 51 and to low-voltage switching device 53, the electric conductors 40 being strip-like and sticking out of the link module 50.
  • the electric conductors 40 are preferably covered by providing a shielding 58 of electrically insulating material.
  • the link module 50 is preferably simply pushed from the top side T of the low-voltage switching devices 51, 53 until the connecting devices 30 have clamped the electric conductors 40 of the link module 50.
  • the link module 50 may further comprise a wall 57 at least partly covering area between the transverse faces of the low-voltage switching devices 51, 53, the wall 57 preferably consisting of electrically insulating material.
  • the link module 50 preferably further comprises connecting slots, rails or latch noses (omitted from Fig. 4) adapted to match with corresponding latch noses, rails or latch openings (omitted from Fig. 4) of said low-voltage switching devices 51, 53.
  • the link module 50 and said latch noses, rails or latch openings it is preferably ensured that the effects of plasma that may escape from one or more of the low-voltage switching devices 51, 53 in the event of a the low-voltage switching device 51, 53 breaking a short circuit will not cause the link module 50 or the system comprising two switching low-voltage switching devices 51, 53 connected via the link module 50 will not explode. This may require some considerations about strength of materials, especially what comes to dimensioning of the latch noses, rails or latch openings.
  • FIG. 5 shows a group of low-voltage switching devices 51, 63.
  • the low-voltage switching device 51 comprises a plurality of connecting devices 30 whereas the low-voltage switching device 63 comprises a plurality of spring-force clamps 55 only.
  • One side of the contacting element 50 is now pushed into the spring-force clamp 55, whereas the other side of the contacting element 50 is pushed into a series of the connecting devices 30 according to the invention.
