Definitions

  • the invention relates to the field of low-voltage electrical cable connections and cable connectors, and in particular to clamping contacting elements, insulation displacement connectors and connector terminal blocks as well as a method of production thereof. It relates to methods and apparatusses according to the opening clause of the claims. Such devices find application, e.g., in industrial cabinets or in residential installations.
  • Such a low-voltage cable connector is known from the published European patent application EP 0 893 845 A2.
  • That connector is an insulation displacement connector (IDC), i.e, a connector that does not require stripping of a cable insulation prior to making the connection to the cable conductor.
  • the IDC has a contact spring with two spring legs for contacting a cable. The insulation of a cable inserted into the IDC is cut through by means of the legs, such that the cable conductor ends up in an open slit formed between the two legs such that the legs electrically contact it and hold it.
  • a disadvantage of such a cable connector is, that two separate parts (contact spring plus power spring) must be manufactured and assembled, and that the range of diameters of cable conductors that can be safely contacted by the cable connector is rather limited.
  • the goal of the invention is to create an electrical cable connector and a method for electrically contacting a cable that do not have the disadvantages mentioned above.
  • a cable connector and a method for electrically contacting a cable shall be provided that can be used for safely contacting cables of a wide range of conductor diameters, and at the same time requires a small amount of space.
  • a connector terminal block comprising such a cable connector and a method of production of such a cable connector is provided.
  • the cable connector for making an electrical contact with a cable conductor of a cable comprises two legs, at least one of which can make electrical contact with a cable conductor inserted into the cable connector into a contacting position, and the two legs are capable of exerting a contacting force on a cable conductor in the contacting position.
  • the cable connector is characterized in that, when there is no cable inserted in the cable connector, the legs exert an non-vanishing initial force on each other.
  • the cable connector has two prestressed legs. Ends of the legs press against each other with some force prior to the insertion of any cable into the connector.
  • the contacting force can be a contacting force for holding the cable conductor in the contacting position.
  • the cable connector can make electrical contacts with one or more cable conductors, i.e., there can be two, three or more cables with cable conductors to be contacted by the cable counductor.
  • the cable connector with prestressed legs provides for a connector, which can make an electrical contact with cables of a wider range of cable sizes (cable conductor diameters), while having the same width and generally the size as a known connector; or, worded alternatively, the cable connector may be of a reduced width or of a generally reduced size, while still permitting to safely connect the same range of cable conductor diameters; or, the cable connector provides for a combination of both.
  • a narrower connector or connector block permits a larger number of connectors or connector blocks on the same rail length and thereby an increased number of connections in the same cabinet space.
  • a cable connector according to the invention has a force-displacement-characteristic for the opening of the two opposing legs with an initial force greater than zero at zero opening, i.e., when the two legs touch at their tips or when a slit formed between the ends of the legs is not yet open.
  • a contacting force at a small opening between the ends of the legs is higher than a contacting force without the prestress at the same small opening and/or a contacting force at a large opening, where a maximum permitted stress level of the leg material is reached, is smaller than a contacting force without the prestress at the same large opening.
  • the maximum permitted stress level is defined through the transition from elastic deformation of the legs to plastic deformation of the legs. Since a cable connector shall usually be used many times, i.e., many insertions and extractions of cables, it is necessary to remain in the elastic region, since otherwise a thin cable will afterwards not be safely contacted anymore.
  • the initial force (offset in the force-displacement-characteristic) and the overall spring constant (slope of the force-displacement-characteristic) of the cable connector can be chosen such, that an optimized small and leight-weight cable connector can be designed. For example: Adjusting the initial force and the spring constant such, that cable conductors of a minimal diameter to be contacted are helt with a minimal required force, and cable conductors of a maximal diameter to be contacted widen the slit between the legs just so far, that a plastic deformation does just not yet take place.
  • the invention allows for a more efficient use of the metal sheet material, in particular a wider range of cable sizes with the same connector width, or a smaller connector width for the same range of cable sizes.
  • An additional advantage is, that the force needed for the insertion of a cable (this force must usually be provided by an operator who makes the cable connection using the cable connector) can be chosen to be smaller, and also the range of forces to be applied for the insertion of a cables of a range of cable conductor diameters can be chosen to be smaller, which results in a more ergonomic operation of the connector.
  • the cable connector can be formed integrally, or it may comprise several parts.
  • the force may be provided (mainly) by the legs, or by an additional power spring.
  • both legs contact an inserted cable in the contacting position.
  • the whole leg is electrically conductive.
  • the cable connector is designed such that it is of symmetrical shape.
  • the cable connector has an insertion opening for inserting a cable conductor into the cable connector into the contacting position.
  • an insertion opening for inserting a cable conductor into the cable connector into the contacting position.
  • the cable connector is designed for making electrical contact with cable conductors of a diameter between a minimum diameter and a maximum diameter, wherein the initial force amounts to at least 5%, in particular at least 10% or at least 20%, of the contacting force exerted on a cable conductor of the minimum diameter in the contacting position. It can also be preferred to be at least 50% of that force.
  • the cable connector is designed for making electrical contact with cable conductors of a diameter between a minimum diameter and a maximum diameter, wherein the cable connector is deformed only elastically through insertion of a cable conductor of the maximum diameter into the contacting position.
  • a connector terminal block according to the invention is characterized in that it comprises at least one cable connector according to the invention and has the corresponding advantages.
  • the method of production of a cable connector for making an electrical contact with a cable conductor of a cable comprising two legs, at least one of which can make electrical contact with a cable conductor inserted into the cable connector into a contacting position, and with the two legs capable of exerting a contacting force on a cable conductor in the contacting position, comprises that the two legs are formed and arranged in such a way, that they exert a non-vanishing initial force on each other, when no cable is inserted between them.
  • This method can in particular be used to manufacture a cable connector according to the invention.
  • an elastic deformation in at least one section of the cable connector is performed
  • the contact element is a bent piece of sheet metal.
  • the two legs are welded to each other while being pressed against each other.
  • the method according to the invention for electrically contacting a cable having a cable conductor comprises the steps of:
  • Fig. 1 schematically shows a perspective view of a cable connector 19 according to the invention with a cable 1 having a cable conductor 2 and a cable insulation 3.
  • the cable connector 19 is a cutting clamping connector 19 designed as an isulation displacement connector 20 (IDC).
  • the cable connector 19 has two legs 190, the ends of which form a slit 192. Through an insertion opening 196, which in addition functions as a cutting element for removing the insulation 3, a cable 1 can be inserted into the slit 192.
  • the cable conductor 2 reaches a contact position when it contacts the legs 190 and is helt in that position by a force applied to the conductor 2 via the legs 190. That force is symbolized in Fig. 1 as two open arrows.
  • width W can be reduced with respect to known cable connectors suitable for connecting a given range of cable conductor diameters by having prestressed legs 190, i.e., legs 190 that not only touch each other when no cable is inserted, but which exert an initial force on each other when no cable is inserted.
  • the open arrows in Fig. 1 also symbolize that initial force.
  • Fig. 2 shows force-displacement-characteristics according to the state of the art (dashed) and according to the invention (solid line).
  • the initial force f0 according to the state of the art is zero. This results in a contacting force f1 at an intended minimal conductor diameter d1. At an intended maximum conductor diameter d2, a contacting force f2 results.
  • the initial force f0' is greater than zero. This results in a contacting force f1' at the intended minimal conductor diameter d1, which can be greater than f1, even if the spring constant (slope of the line) is smaller than in the case of a cable connector according to the state of the art. Accordingly, a safe contact at small diameters (d1) can be achieved with a weaker and therefore smaller spring.
  • a contacting force f2' results, which can be chosen to be smaller than f2.
  • the cable connector 19 can be designed such, that at d2 only elastic deformations of the cable connector take place.
  • Fig. 3 show schematically the contact resistance R as a function of the contact force F.
  • the contact force f1' can easily be selected to be higher than f1, resulting in a strongly improved contact at small conductor diameters d1; and f2' may be chosen much smaller than f2, which difference ⁇ F of forces F nevertheless results only in a very small decrease ⁇ R of the contact resistance R, so that still a sufficiently small contact resistance is achieved for large diameters d2.
  • d2 large diameters
  • only moderate insertion forces are required, and the range of forces to be applied is much smaller for the same range of diameters, both resulting in an improved operability of the cable connector.
  • Fig. 4 shows a cut through a cable connector 19 indicating the zone 195 of maximum stress upon cable insertion.
  • the cut runs in a plane perpendicular to the direction M of the movement of the cable during insertion (cf. Fig. 1)
  • the cable connector is of symmetrical shape with respect to the symmetry line S.
  • the dashed line shows the leg 190 before cable insertion, the solid line shows the leg 190, when a cable is inserted into the contact position.
  • the cable connector 19 is substantiall "U”-shaped with bottom bends Bb, between which the "U” has a preferably straight bottom line; and with top bends Bt near the ends 191 of the legs 190. Between a bottom bend Bb and a top bend Bt the "U” is preferably of straight shape. From numerical simulations it has been found that for such a "U"-shaped cable connector 19 the zone 195 of maximum stress is on the inside of the bottom bends Bb.
  • the range of cable diameters to be connected to a cable connector 19 determines its overall size and in particular its width W. This is because (1.) the deformation of the two legs when the largest permitted cable is inserted shall remain within the elastic limit of the material. If the insertion of the largest permitted cable would lead to a plastic deformation, the connector would be damaged for a potential subsequent use, e.g., the insertion of a cable of smaller size.
  • the minimum contact force required for the smallest cable defines the spring constant for an opening between the two legs and hence also the force experienced by an inserted cable of largest size (f2 in Fig. 2).
  • this force (f2) cannot be freely chosen according to the actual cutting force requirement and contact resistance requirement (cf. Fig. 3).
  • the resulting force will be larger than the minimum force required for a sufficiently low contact resistance (cf. Fig. 3).
  • the combined requirements of the spring constant (resulting from the specification of the smallest cable size to be connected) and the largest opening (for the largest cable size to be connected) define the maximum strain state suffered by the material. That maximum strain state is reached at the transition from elastic to plastic deformation. Usually the maximum strain is reached at the inner radius of the bottom bend Bb (cf. Fig. 4).
  • Fig. 5 schematically sketches a first method of production of a cable connector 19.
  • the connectors are preferably manufactured by cutting and subsequently bending a piece sheet metal.
  • Fig. 5 shows a schematic sketch of a first possible manufacturing sequence.
  • the sheet metal 30 and the connector are shown in a cut along a plane perpendicular to the direction of the movement M of the cable during cable insertion (cf. Fig. 1), which corresponds to a plane perpendicular to the slit 192 (cf. Fig. 1).
  • Fig. 5a a suitably cut piece of sheet metal 30 is shown.
  • two legs 190 and two bottom bends Bb are formed, see Fig.
  • the plastic deformation is such, that the ends of the legs 190 will then nearly touch each other.
  • the dash-dotted line depicts the symmetry line of the connector.
  • Fig. 5c is shown, that the legs 190 are then, close to their ends, bent plastically (black arrows), while the legs 190 are spread elastically (open arrows).
  • black arrows the legs 190 are bent plastically
  • open arrows the legs 190 are spread elastically
  • two top bends Bt are formed, and the two legs touch each other at their ends, and the legs 190 are prestressed, see Fig. 5d.
  • the two open arrows in Fig. 5d shall idicate the initial force, which the legs 190 exert on each other.
  • Fig. 6 a second manufacturing sequence is shown in the same kind of representation as Fig. 5.
  • Fig. 6a a suitably cut piece of sheet metal 30 is shown.
  • plastic deformation black arrows
  • two top bends Bt are formed, see Fig. 6b, which are located near the ends (contact edges) of the two legs to be formed.
  • one bottom bend Bb is formed through plastic deformation (black arrow, Fig. 6c).
  • the angle at the bottom bend Bb is selected to be larger than the angle that would bring the end exaclty to the dash-dotted symmetry line.
  • Fig. 7 a third manufacturing sequence is shown in the same kind of representation as Figs. 5 and 6.
  • Fig. 7a a suitably cut piece of sheet metal 30 is shown.
  • plastic deformation black arrows
  • two top bends Bt are formed, see Fig. 7b, which are located near the ends (contact edges) of the two legs to be formed.
  • a dent Bd is formed through plastic deformation (black arrow, Fig. 7c). This center dent Bd points towards the location, where the ends of the legs will end up.
  • two bottom bends Bb are formed by plastic deformation, such that the two legs are bent towards each other, preferably until they touch each other at the symmetry line, see Fig. 7d.
  • the two legs are helt in their position, and the direction of the center bend is reversed through plastic deformation (black arrow, Fig. 7e), so that it points away from the ends of the legs.
  • plastic deformation black arrow, Fig. 7e
  • an elastic deformation takes place near the bottom bends (not indicated).
  • the ends of the opposing legs press against each other with an initial force.
  • a connector with prestressed legs is thus formed.
  • the depth of the dent Bd is typically smaller than indicated in Fig. 7.
  • Fig. 6 it is also possible to firstly create the first bottom bend Bb (see Fig. 6c) and then provide for the top bends Bt (see Fig. 6b). Or, in Fig. 7, first the center dent Bd (see Fig. 7c) can be created, and then the top bends Bt are done (see Fig. 7b).

  • a memory-shaped alloy which converts its shape to some prelearned shape through a heat treatment.
  • the (not-yet-prestressed) connector is formed at a temperature different from the envisaged working temperature of the connector, such that the connector changes its shape when cooling down or heating up to a temperature corresponding to the operating conditions.
  • a bimetal can be used in the same way.
  • Another possibilty would be to fix two formerly separate legs with respect to each other, e.g., by welding, by glueing, or by mechanically fixing, while the legs are pressed against each other (elastically), such that there is a prestress between the two legs in the cable connector after the fixing.

  • the task of this connector terminal is to electrically contact a cable 1, which has a cable conductor 2 and a cable insulation 3.
