Description

The invention relates to a conductor terminal with a housing and a contact insert for making electrical contact with an electrical conductor to be connected to the conductor terminal, and with an actuating element, with which at least one movable part of the contact insert can be moved from a first position to a position deviating from the first position by actuating the actuating element second position can be moved, wherein the actuating element has at least one lever arm, by which the actuating element can be actuated manually or by external force, the actuating element being pivotably mounted in the housing via a pivoting mechanism.

Such a conductor terminal is for example from EP 3 787 121 A1 known.

The invention is based on the object of specifying a conductor connection terminal with an improved actuating mechanism.

This object is achieved with a conductor terminal of the type mentioned at the outset in that the actuating element is guided via a forced guidance mechanism along a predetermined forced guidance contour in the housing, through which at least one positively guided region of the actuating element is pivoted when the actuating element is pivoted in a direction of movement deviating from the pivoting movement along the forced guidance contour is led. In this way, the operating mechanism of the conductor terminal is optimized. A guided rotational movement of the actuating element can be achieved by the forced guidance mechanism. The actuating element can be pivoted with respect to the movement of the lever arm. The forcibly guided area of the actuating element then leads through the pivoting movement defined by the forced guidance contour. For example, the forced guidance contour can be a substantially linear contour. As an alternative or in addition, at least part of the restricted guidance contour can also be designed in the shape of an arc, in which case the arc shape can have a contour that deviates from the pivoting contour of the pivoting mechanism. The restricted guidance contour can be designed, for example, as a guide link.

The actuating element can be actuated manually by the user via its lever arm. The actuating element can also be actuated via its lever arm by an external force generated in some other way, e.g. via a robot or another machine.

With such an actuating mechanism, a clamping leg of a clamping spring, for example, can be deflected as a moving part of a contact insert, e.g. in order to open and close a clamping point by means of the actuating element. The moving part of the contact insert can also be another component, e.g. another clamping contact, e.g. an insulation displacement contact.

In the first position, for example, a clamping point formed with a clamping leg of a clamping spring can be closed, in the second position the clamping point can be open. In the case of an insulation displacement contact, it can be in a neutral position in the first position and in electrically conductive contact with an electrical conductor in the second position.

With such an actuating mechanism, the part of the contact insert to be moved by means of the actuating element can be actuated with little effort, i.e. with a small actuating force to be applied. For example, the actuating force can be increased by the actuating element, e.g. in a ratio of 2:1.

The first position of the movable part of the contact insert can correspond to a first end position of the pivoting range of the actuating element. The second position of the movable part of the contact insert can correspond to a second end position of the pivoting range of the actuating element.

The actuating mechanism can be designed in such a way that the translation of the actuating force changes during the pivoting movement from the first end position to the second end position, e.g. from a low translation value in the first end position to a higher translation value towards the second end position.

In addition, the lever arm can be used to signal in a visually easy-to-recognize manner that the actuating element is in the first or second end position.

According to an advantageous embodiment of the invention, it is provided that the part of the contact insert that can be moved by the actuating element can be moved by the forcibly guided region of the actuating element when the actuating element is pivoted. In this way, the moving part of the contact insert, e.g. the clamping leg, can be guided in a manner defined by the restricted guidance contour. The moving part of the contact insert is therefore not bound to the pivoting movement in its movement sequence, but can, for example, perform a substantially linear movement with a substantially linear restricted guidance contour.

According to an advantageous embodiment of the invention, it is provided that the lever arm is immovably coupled to a part of the pivoting mechanism assigned to the actuating element and/or immovably to the forcibly guided region of the actuating element. The lever arm is thus rigidly coupled to the part of the pivoting mechanism assigned to the actuating element and/or to the forcibly guided area of the actuating element. In this case, the part of the pivoting mechanism assigned to the actuating element can be immovably or rigidly coupled to the forcibly guided region of the actuating element. As a result, large actuating forces can be transmitted to the movable part of the contact insert by means of the lever arm in a manner that is particularly pleasant and ergonomic for the user in the case of manual actuation.

According to an advantageous embodiment of the invention, it is provided that the actuating element is mounted in a floating manner via the pivoting mechanism. This has the advantage that the bearing elements of the pivoting mechanism can be made simple and inexpensive. No special parts with particularly high dimensional accuracy are required. Such a floating mounting means that the part of the pivot mechanism assigned to the actuating element is not pivoted about a fixed pivot axis when pivoted, but rather the pivot axis can move to a certain (generally small) extent during the pivoting movement.

According to an advantageous embodiment of the invention, it is provided that the part of the pivoting mechanism assigned to the actuating element has a first circular contour over at least half of its outer circumference. The first circular contour can be guided in an at least partially circular contour of the housing. This allows the pivoting mechanism to be provided with simple and inexpensive means.

According to an advantageous embodiment of the invention, it is provided that the forcibly guided area of the actuating element has a second circular contour over at least half of its outer circumference. This has the advantage that the forcibly guided area of the actuating element can slide along the forcibly guided contour with little resistance during pivoting and does not unintentionally catch or jam on it.

According to an advantageous embodiment of the invention, it is provided that the first circular contour merges directly into the second circular contour. This promotes a compact construction of the conductor connection terminal. The actuating element can thus have the shape of the number 8 in the region of the first and the second circular contour in a side view.

According to an advantageous embodiment of the invention, it is provided that the first circular contour has a larger radius than the second circular contour. In this way, large forces can be absorbed via the pivoting mechanism and be transferred. In addition, the space required for the forcibly guided area of the actuating element is small. For example, the first circular contour may have a radius that is at least 1.5 times the radius of the second circular contour.

According to an advantageous embodiment of the invention, it is provided that in at least a first end position of the pivoting range of the actuating element, the lever arm is arranged essentially at right angles to the central axis of the restricted guidance contour. In this way, at the beginning of the pivoting movement, the actuating element transmits the actuating movement and actuating force relatively directly, i.e. with little transmission, to the forcibly guided area of the actuating element.

According to an advantageous embodiment of the invention, it is provided that in at least a second end position of the pivoting range of the actuating element, the lever arm is arranged essentially parallel or in alignment with the central axis of the restricted guidance contour. In this way, the lever arm in the second end position can, for example, transition into the restricted guidance contour. In addition, a greater translation of the actuating movement and actuating force can be achieved in the second end position.

According to an advantageous embodiment of the invention, it is provided that the part of the contact insert that can be moved by the actuating element is connected to the actuating element via a joint. In this way, the combined pivoting/forced guidance movement of the actuating element can be decoupled in a simple manner from the movement sequence of the movable part of the contact insert. The moving part of the contact insert can, for example, perform a substantially linear movement. In an advantageous embodiment, the axis of rotation of the joint runs essentially parallel to the pivoting axis of the pivoting mechanism. The pivoting axis of the pivoting mechanism can run essentially perpendicularly to the central axis of the restricted guidance contour.

According to an advantageous embodiment of the invention, it is provided that the part of the contact insert that can be moved by the actuating element is designed as an insulation displacement contact (IDC contact) is formed. This has the advantage that, in combination with the advantageous actuating mechanism, a conductor connection terminal for flat conductor contacting or sheathed cable can be implemented using an IDC contact with a relatively low actuating force requirement and switching position display of the actuating element. Such an insulation displacement contact is used for direct electrical contacting of an electrical conductor that is encased in insulation. Such an insulation displacement contact has, for example, a sharp-edged blade section that is designed to cut open the insulation of the electrical conductor. The electrical contact is then made by appropriately clamping the cut-open electrical conductor. In an advantageous embodiment, the insulation displacement contact can be designed according to one of the embodiments of the invention explained below.

According to a further aspect, the present invention relates to an insulation displacement contact for making electrical contact with an electrical conductor sheathed in insulation, the insulation displacement contact having a sharp-edged cutting edge section which is designed to cut open the insulation, the insulation displacement -Contact has a clamping contact section which is spaced apart from the blade section and is designed for clamping and permanently electrically contacting the electrical conductor in the region of the insulation which is cut open by the blade section. In the case of the insulation displacement contact, the blade section and the clamping contact section are spatially separated from one another. This has the advantage that the two sections can be optimized for their respective function, namely the efficient cutting open of the insulation on the one hand and the efficient clamping and permanent contact of the electrical conductor on the other without the sharp-edged cutting edges causing excessive damage to the conductor electrical conductor occurs.

According to an advantageous embodiment of the invention, it is provided that the clamping contact section has at least one flat contact area that is not suitable for cutting the insulation and is set up for flat contact with the electrical conductor. This has the advantage that damage to the electrical conductor is avoided by the clamping contact section and at the same time a relatively large contacting surface is provided, so that the insulation displacement contact can contact electrical conductors with particularly low resistance, which allows the transmission of high currents.

According to an advantageous embodiment of the invention, it is provided that the insulation displacement contact is designed as a fork contact with two opposing fork prongs, between which a free space for receiving the electrical conductor is formed. As a result, an electrical conductor can first be partially stripped of insulation via the cutting section and then clamped between the fork tines via the clamping contact section in a particularly precise and targeted manner. In this case, the opposite forks can have respective opposite clamping contact sections whose flat contact areas are arranged at least predominantly parallel to one another.

According to an advantageous embodiment of the invention, it is provided that a smaller opening angle is formed between the fork tines in the clamping contact section than in the blade section. This has the advantage that the cutting surfaces of the cutting section are guided at a favorable, oblique angle of attack to the electrical conductor, which allows the insulation to be cut open in a particularly efficient and gentle manner. On the other hand, due to the smaller opening angle in the clamping contact section, the electrical conductor is clamped and fixed in a particularly reliable manner, so that it does not easily become detached again from the insulation displacement contact.

According to an advantageous embodiment of the invention, it is provided that a negative opening angle is formed between the fork prongs in the clamping contact section in the unloaded state of the insulation displacement contact. Such a negative opening angle in the unloaded state means that the distance between the opposing fork tines increases as the distance from the transition area between the cutting edge section and the clamping contact section increases. The smallest distance between the fork tines is therefore present in the transition area between the blade section and the clamping contact section. As a result, the insulation displacement contact can be fixed particularly securely to the electrical conductor by clamping.

According to an advantageous embodiment of the invention, it is provided that an opening angle in the range of 50° to 150° is formed between the fork tines in the blade section. This allows the insulation of the electrical conductor to be cut open particularly efficiently by the cutting section.

According to an advantageous embodiment of the invention, it is provided that the cutting edge section merges into the clamping contact section via an intermediate section, with a larger opening angle being formed in the intermediate section between the fork tines than in the cutting edge section. By means of such an intermediate section, the areas of the insulation separated from one another by the cutting section can be pressed away from one another in a simple and particularly efficient manner. In the cut-open area, the insulation is thus pushed apart somewhat by the intermediate section, so that a reliable electrical contact with the electrical conductor can be established by the following clamping contact section.

According to an advantageous embodiment of the invention, it is provided that one or both fork tines in the blade section are only chamfered on one side to form a blade. In this way, relatively large cutting surfaces are provided, so that relatively thick insulation can also be reliably severed by the cutting section.

In addition to the insulation displacement contact mentioned, the conductor connection terminal can also have another insulation displacement contact, for example at a point in the housing at a distance from the first-mentioned insulation displacement contact. In this way, for example, a further electrical conductor can be connected to the conductor connection terminal using insulation displacement technology. Alternatively or in addition to the further insulation displacement contact, the conductor connection terminal can have a sensor system in order to record at least one electrical or other physical parameter in the conductor connection terminal, e.g. the current flow through the contact insert, the voltage at the contact insert and/or the temperature at the contact insert or another part of the conductor terminal.

The actuating element can be coupled in a form-fitting manner to the movable part of the contact insert via form-fitting elements. In this way, a movable mounting of the movable part of the contact insert and the actuating element is made possible. For example, the positive connection between the actuating element and the movable part of the contact insert can comprise a multi-point support or connection, e.g., a three-point support or connection. This increases the actuating surface, which reduces the effort required to actuate the moving part of the contact insert. The term multi-point support or connection is to be understood in such a way that the corresponding connection points do not have to have a full-surface support of the respective surfaces of the actuating element and moving part of the contact insert, but instead there is a punctiform or linear connection, for example.

For the purposes of the present invention, the indefinite term "a" is not to be understood as a numeral. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component". If angles are specified in degrees, these refer to a circular measurement of 360 degrees (360°).

The invention is explained in more detail below on the basis of exemplary embodiments using drawings.

The Figures 1 and 2 show a conductor terminal 1 in different views from the outside. The conductor terminal 1 is designed as a lever-operated insulation displacement terminal, with which an electrical conductor 9 inserted into a housing 2 of the conductor terminal 1 can be contacted directly by means of an insulation displacement contact arranged movably in the housing 2, without a separate stripping step having to be carried out beforehand . The electrical conductor 9 has an insulation 90 through which an inner conductor 91 is encased and insulated from the environment. The movable insulation displacement contact can be actuated manually or by external force via an actuating element 5 designed like an actuating lever, ie moved from a first position to a second position deviating from the first position and, if necessary, out of the second position again be moved to the first position. The housing 2 can be designed as an insulating material housing. The exact structure of the conductor terminal 1 will be explained below using various sectional views. In the Figures 1 and 2 the corresponding section planes are drawn.

The figure 3 shows the conductor terminal 1 in the sectional plane BB. A part of the actuating element 5 can be seen, to which the mentioned insulation displacement contact 4 is fastened. In the exemplary embodiment shown, the insulation displacement contact 4 also forms the part 7 of the contact insert 6 of the conductor terminal 1 that can be moved by means of the actuating element 5. In the lower part of the housing 2, a housing area has a receiving channel 20 for the electrical conductor 9, which for supporting and supporting the electrical conductor in the housing 2 is used. You can also see the front ends of an insulation displacement section 40 of the insulation displacement contact 4 in the lower area.

In the figure 3 a further section plane FF is also drawn in.

The figure 4 shows the conductor terminal 1 in the sectional plane CC. It can be seen that the actuator 5 as manually by the user or by External force to be actuated area has a lever arm 50. In the figure 4 the actuating element 5 is in a first end position. In this first end position, the lever arm 50 is arranged essentially parallel to the receiving channel 20 for the electrical conductor 9 , so that the electrical conductor 9 also runs essentially parallel to the lever arm 50 in this position of the actuating element 5 . A forced guidance contour 24, through which the actuating element 5 is guided during a pivoting movement, extends in its longitudinal direction essentially at right angles to the lever arm 50.

You can see in the figure 4 also a receiving section 51 on the actuating element 5, which serves to receive and fix the insulation displacement contact 4 on the actuating element 5. The insulation displacement contact 4 has a fixing area 41 via which it is attached to the actuating element 5 in the receiving section 51 . The fixing area 41 can have a contour bent by more than 180°. Within this curved fixing area 41, a fixing pin 52 of the actuating element 5 can be arranged, which forms a joint 8 with the fixing area 41, ie an articulated connection.

The actuating element 5 has a pressure surface 56 on the receiving section 51 which, when the actuating element 5 is pivoted, comes into contact with a pressure receiving section 42 of the insulation displacement contact 4 in order to move it downwards by compressive force, as in FIG figure 6 is evident.

The insulation displacement contact 4 extends downwards from the fixing area 41, ie towards the electrical conductor 9, essentially in the middle along the restricted guidance contour 24 up to the insulation displacement section 40. A plug contact can be on the insulation displacement contact 4 44, 45 may be arranged, which is used for electrically contacting a busbar 3 of the conductor terminal 1, which forms another part of the contact insert 6 of the conductor terminal 1. An electrically conductive connection can be made from the busbar 3 to the electrical conductor through the plug-in contact 44, 45 when the latter is connected to the insulation displacement section 40.

Based on figure 5 , which shows the conductor terminal 1 in the sectional plane FF, is intended to explain the pivotable mounting of the actuating element 5 via a pivoting mechanism 23, 53 and also the additional forced movement of the actuating element 5 by a forced guiding mechanism 24, 54. In the exemplary embodiment shown, the pivoting mechanism is formed by a bearing disk 53 arranged, for example, on the lateral edge of the actuating lever 5 or, if necessary, also by bearing disks 53 arranged on both lateral edges on the left and right, which has a part of its outer circumference, for example over at least half of its outer circumference, first have circular outline. The bearing disk 53 with the first circular contour is loosely or floatingly mounted in a rounded bearing contour 23 of the housing 2 assigned as a counterpart. It can be seen that the dimensions of the bearing contour 23 are significantly larger than the dimensions of the bearing disk 53.

A positively guided area 54 is present on the actuating element 5 and is guided in the positively guided contour 24 . In the exemplary embodiment shown, the forced guidance contour 24 extends essentially linearly from top to bottom, ie with its central axis M in a direction essentially perpendicular to the longitudinal direction of the receiving channel 20. The forced guided area 54 has over part of its outer circumference, e.g. over at least half of its Outer perimeter, a second circular contour. In this way, the positively guided area 54 can slide with little friction along the positively guided contour 24 during a pivoting movement of the actuating element 5 . The one in the figure 5 Forced guidance contour 24 shown is also rounded at its ends, but this is not absolutely necessary. It can be seen that the slightly smaller second circular contour of the forcibly guided area 54 merges into the slightly larger circular contour of the bearing disk 53, so that the actuating element 5 has the shape of the number 8 in the sectional view shown.

The figure 6 shows the conductor terminal 1 in the sectional view DD. In this case, the actuating element 5 has now been moved into a second end position in that it has been pressed down by a compressive force transmitted from the pressure surface 56 to the pressure-receiving section 42 .

In this second end position, the insulation displacement contact 4 makes contact with the electrical conductor 9. In addition, the plug contact 44, 45 makes contact with the conductor rail 3 figure 6 corresponds to the receiving section 51 of the actuating element 5, is now located at the lower end of the restricted guidance contour 24. In the upper region of the housing 2, in which the lever arm 50 is arranged in the first end position, a free space 22 is now formed. In this way, the lever arm 50 can signal the operating state of the conductor terminal 1 in a way that can be easily checked visually.

In the figure 6 It can also be seen that the conductor terminal 1 can have an electrical component 10 which is present in addition to the insulation displacement contact 4 or the contact insert 6 . The electrical component 10 can be designed, for example, as a further insulation displacement contact and/or as a sensor system for detecting at least one physical variable of the conductor connection terminal, for example for detecting the current, the voltage or a temperature.

The figure 7 shows the conductor terminal 1 in the sectional view GG. The actuating element 5 is in its first end position comparable to the representation of figure 4 . It can be seen from the selected sectional plane that the lever arm 50 can have an inner hollow channel 55 , for example a hollow channel that tapers towards the receiving section 51 . In this way, the lever arm 50 is also suitable for actuation by means of an actuating tool, for example a screwdriver. The tip of a screwdriver can be inserted into the inner hollow channel 55 in a largely form-fitting manner.

The figure 7 also clarifies the interaction between the actuating element 5 and the movable insulation displacement contact 4. The pressure surface 56 arranged on the actuating element 5 can again be seen, which exerts a compressive force on the pressure-receiving section 42 of the insulation displacement contact 4 when the actuating element 5 is actuated accordingly can. For the opposite movement, i.e. for pulling the insulation displacement contact 4 back into the initial position shown, a pulling element 57 is arranged on the actuating element 5, which pulls through a cutout 48 into the inner area of the insulation displacement contact 4 can engage and withdraw it again by a tensile force which is exerted on the side of the fixing region 41 opposite to the pressure-receiving section 42 . The tension element 57 can be designed in the manner of a driver or as a driver hook. The figure 8 clarifies the above-mentioned cut-out 48 on the insulation displacement contact 4, through which the tension element 57 can intervene there.

The figure 8 shows the conductor terminal 1 in the sectional view AA. The actuating element 5 is in the second end position, comparable to FIG. 6. It can be seen that the lever arm 50 covers a pivoting angle of approximately 90° from the first end position to the second end position.

Based on Figures 9 to 11 a first embodiment of an insulation displacement contact 4 is explained, which can be used, for example, as an insulation displacement contact 4 of the conductor terminal 1 . The insulation displacement contact 4 has an insulation displacement section 40 which is used to cut open and electrically contact an electrical conductor 9 . In the illustrated embodiment, the insulation displacement contact 4 has the shape of a fork contact with two opposite forks 46, 47, at least in the insulation displacement section 40. A free space for accommodating the electrical conductor 9 is formed between the forks 46, 47.

The insulation displacement contact 4 or its insulation displacement section 40 is divided into three different areas, namely starting from the free end (below), first a blade section 60, which is designed to cut open the insulation 90, followed by an intermediate section 61 and subsequently a clamping contact section 62.

In the cutting section 60, the fork tines 46, 47 each have opposite sharp-edged cutting edges 63, via which the insulation 90 of the electrical conductor 9 can be cut open. Instead, there are fewer sharp edges in the clamping contact section 62, but rather contact surfaces 65 which are parallel to one another or are aligned at a small angle to one another and which allow contact to be made over the entire surface of the inner conductor 91 without damaging it. Man recognizes eg in the figure 11 that the fork tines 46, 47 in the intermediate section 61 have a raised area in the manner of a hump, which protrudes beyond both the cutting edge 63 and the contact surface 65. Such an intermediate section 61 allows the insulation 90 severed by the cutting edges 63 to be additionally pushed away, so that the subsequent contact surface 65 can be in good contact with the inner conductor 91 unhindered by the insulation 90 .

You can see in the figure 10 that the insulation displacement contact 4 from the insulation displacement section 40 in the connecting section 43, then in the fixing area 41 and then after a further bend in the area of the plug contact 44 transitions.

The Figures 12 and 13 show a second embodiment of an insulation displacement contact 4. It can be seen that an opening angle α is formed between the fork prongs 46, 47 in the blade section 60, for example in the range from 50° to 150°. A significantly smaller opening angle β between the forks 46, 47 is formed in the clamping contact section 62, in particular a negative opening angle, which means that the width of the free space between the forks 46, 47 increases upwards towards the fixing area 41.

In both embodiments of the insulation displacement contact 4, the fork prongs 46, 47 can in particular be tapered, i.e. they can have a narrowing point 66 on their edge sides facing away from one another, which can be found, for example, in the area between the lower third and the middle of the insulation displacement contact. Contact 4 is arranged seen in the longitudinal direction. For example, the tapering point 66 can be arranged in the clamping contact section 62 .

It can also be seen that on one or on both fork arms 46, 47 there can be additional spacers 67 protruding in the direction of the opposite fork arm 46, 47. These spacers 67 can be formed as an additional, relatively short, pointed edge in the area of the contact surfaces 65 on the forks 46, 47. For example, the spacers 67 can be made significantly narrower and more pointed than the contact surfaces 65 . The spacers 67 are in an advantageous position Configuration of the invention seen from the free end at a point of the forks 46, 47 behind the cutting edges 63 and the intermediate sections 61, for example immediately behind the intermediate sections 61. In the longitudinal direction of the forks 46, 47, the spacers 67 can have a length of, for example, less than the half the length of the cutting edges 63 have.

When applying the insulation displacement contact to the electrical conductor, the spacers 67 allow the insulation 90 to be slightly recut and/or the insulation areas that have already been divided to be additionally pressed apart, so that a secure contacting of the inner conductor 91 by the contact surfaces 65 is ensured even better .
