Description

Terminal, tool and assembly for connecting jacketed electrical conductors

Technical Field

The present utility model relates to a terminal for connecting electrical conductors and a tool for establishing a connection of electrical conductors to the terminal. The utility model also relates to a method for establishing a connection of an electrical conductor to a terminal and to an assembly of a terminal and a tool.

Background

The art is aware of clip connection techniques (insulation displacement connection, english: "Insulation Displacement Connection", abbreviated: "IDC"). In this case, the electrical contact is usually made by inserting or pressing an electrical conductor into a fork-shaped, resilient clip-type terminal. The insulating layer of the electrical conductor is cut through and the conductive inner conductor of metal is clamped to make contact with the cut-and-clamp terminal.

The clip type terminals have different structures such as a single clip type or a double clip type. The clip terminals must always be matched and selected according to the type of conductor set and the insulating material thereof. Whereby, for example, a contact cross section of about 0.01mm can be achieved ² (enamelled wire) to about 6mm ² Stranded conductors, solid conductors, and enameled conductors. Furthermore, corresponding tools for establishing a connection of an electrical conductor to a terminal are known from the prior art. Another problem is mainly that for electrical conductors with a larger cross section, correspondingly more force must be applied to connect the electrical conductor to the terminal. In this case, the mechanical load generated may be undesirably transferred to and/or even damage the printed circuit board, the circuit card, etc. on which the terminals are placed.

For example, document DE102015121743A1 describes a tool for connecting an electrical conductor coated with an insulating layer to a clip-type terminal. The tool has a punch element for guiding and a cutting area for cutting the insulation of the electrical conductor before it is inserted into the clamping slot of the clip-on terminal. The tool is provided with pivotable securing means for maintaining a secure engagement with the clip terminals in the use position of the tool.

A pistol-like tool is known from document US3805214a for connecting insulated electrical conductors to an electrical connector in the form of a terminal. The tool has a movable piston with a protruding ratchet for inserting an electrical conductor into a terminal, which actuates a resilient gripping element by means of a corresponding outer edge and surface for securing and releasing the clamp.

Document DE102016114344B3 discloses a leverage tool for connecting an electrical conductor coated with an insulating layer to a clip-type terminal, wherein the leverage tool has, on the one hand, a punch element with a pressing section and a guide element for the electrical conductor and, on the other hand, a support element for holding the clip-type terminal. The guide element engages positively in a guide groove of the clip terminal.

Document DE10048298A1 discloses a conductor connecting element for connecting an electrical conductor to a clip terminal. The conductor connecting element has a connecting body with two U-shaped conductor receiving chambers and a molded part with a thread for actuating a screwable clamping screw in order to press the electrical conductor into a clip-on terminal which is arranged laterally on the conductor receiving chambers by means of pins.

Disclosure of Invention

It is therefore an object of the present utility model to provide an improved terminal, an improved tool and an improved method for connecting an electrical conductor to a terminal.

This object is achieved by the features of the independent claims. Further embodiments and applications of the utility model originate from the dependent claims and are explained in more detail in the following description with reference to the accompanying drawings.

Based on a first general point of regard, the present utility model relates to a terminal for connecting electrical conductors with a sheath, wherein the terminal comprises a first clamping jaw and a second clamping jaw arranged opposite and/or spaced apart from each other, wherein the first clamping jaw has a first clamping element and the second clamping jaw has a second clamping element, which correspond to each other and are at least partially spaced apart from each other to form a clamping slit, wherein the first clamping element is at least partially in contact with the second clamping element in order to form an effective connection between the first clamping element and the second clamping element.

This connection may preferably comprise an electrically conductive connection formed between the terminal and the electrical conductor. The electrical conductor is preferably an insulated electrical conductor or an electrical conductor encased in at least one insulating material.

The first clamping jaw and/or the second clamping jaw may preferably be formed as a metal spring, for example as a leaf spring. In other words, the terminals may be formed as dual spring terminals. The first jaw and the second jaw may preferably be spaced from each other by a common tab.

Preferably, the clamping slit may be formed for receiving an electrical conductor. Preferably, the first clamping element can be in at least partial contact with the second clamping element in the region of the clamping slot.

According to a further aspect of the utility model, the first clamping element and the second clamping element may be arranged in such a way that the effective connection comprises a pivoting or pivoting support between the first clamping element and the second clamping element and/or a locking or latching action for the connected electrical conductor, preferably after the electrical conductor has been received or connected in the terminal, i.e. the clamping slot, and/or a stop or blocking action for the connected or to be connected electrical conductor, preferably when the electrical conductor has been received in the terminal, i.e. the clamping slot.

According to a further aspect of the utility model, it is possible to provide that the first clamping element has a projection for forming an effective connection, which projection at least partially contacts a stop, preferably a cutout, of the second clamping element.

Thus, existing requirements on the installation space and/or the dimensions of the terminals can be taken into account, for example. Furthermore, the terminal can be produced, for example, relatively easily and inexpensively, preferably by means of at least one stamping process and/or at least one bending process.

According to a further aspect of the utility model, it may be provided that the first clamping element is arranged preloaded with respect to one another by the first clamping jaw and the second clamping element is arranged preloaded with respect to one another by the second clamping jaw at least in the connected state of the electrical conductor, preferably at least in sections forming a pressure bond.

For example, it is thereby ensured that the electrical conductor is not only held in the terminal in a form-fitting manner, but is also subjected to a corresponding clamping force.

According to a further aspect of the utility model, it may be provided that the first clamping jaw and/or the second clamping jaw are shaped at least partially in an arc, U-shape, V-shape or fork-shape in the view, preferably in a section view in the direction of the electrical conductors to be connected or connected.

For example, improved mechanical properties, preferably elastic properties, of the terminal in terms of spring action can thereby be achieved.

According to a further aspect of the utility model, the first clamping element and the second clamping element can be arranged to form at least one first connection section and preferably at least one second connection section for connecting the electrical conductors, wherein the at least one first connection section and/or the at least one second connection section in one view, preferably in a side view in the direction of the electrical conductors that have been or are to be connected, have a substantially circular or rounded profile and/or a substantially elliptical or curved profile and/or have a cross section of different dimensions.

The first clamping element may be formed at least partially substantially the same as and/or substantially symmetrically to the second clamping element.

The at least one first connection section and/or the at least one second connection section may preferably be configured and/or formed to be able to connect different electrical conductors having different sized cross sections to the terminal. Preferably with a larger cross-section, for example up to about 35mm ² Can be received in and connected to the terminals. Whereby, for example, a larger current can be transmitted.

The clamping slot forms, in one view, preferably in a side view in the direction of the connected or to-be-connected electrical conductors, at least in some areas a substantially V-shaped contour, which preferably merges into the contour of the first connecting section.

The electrical conductor can thus be guided into the terminal, i.e. into the clamping slot, for example along a path defined on the terminal, without separate guiding elements being required, for example on the tool.

According to a further aspect of the utility model, it may be provided that the first clamping jaw and the second clamping jaw are connected to each other by a common tab, and that the first clamping jaw, the second clamping jaw and the tab are preferably formed substantially in a U-shape in one view, preferably in a cross-sectional view in the direction of the electrical conductors that have been or are to be connected.

The first clamping jaw and/or the second clamping jaw can each have at least in sections two plate-shaped wall sections, which are arranged at a distance from one another, preferably at an angle, and which are connected to one another, preferably by at least one wall section which is at least in sections curved.

According to a further aspect of the utility model, it can be provided that the first clamping jaw and/or the second clamping jaw each have a first spring-elastic clamping jaw section and each have a second spring-elastic clamping jaw section, which is each arranged at a distance from the first spring-elastic clamping jaw section, wherein the first clamping jaw and the second clamping jaw are preferably each connected to one another by means of the first spring-elastic clamping jaw section and a common web.

The wall section, which is at least partially arcuate and connects two flat wall sections arranged at a distance from one another, preferably at an angle to one another, is formed as a second spring-elastic clamping jaw section.

The first and second spring-elastic jaw sections may preferably have a greater extensibility and/or a higher elasticity than the rest of the first and/or second jaws or regions. The first spring jaw section and the second spring jaw section can thus be formed as spring elements, i.e. elements having a spring action.

For example, a terminal having two spring sections on each jaw can thereby be provided, which preferably enables a larger spring path. Furthermore, for example, an almost constant clamping force can be provided thereby via the clamping region, preferably at least via the region of the connecting section. In this way, for example, the accommodation or clamping of electrical conductors of different cross-sections can be optimized.

The first spring-elastic clamping jaw section and/or the second spring-elastic clamping jaw section can be formed at least in sections in an arc shape or preferably at least in sections in the shape of a hairpin bend in one view, preferably in a side view in the direction of the electrical conductors that have been or are to be connected.

For example, a further optimized spring effect of the first contact element and the second contact element can thus be ensured, and thus an optimized clamping effect on the electrical conductor is preferably ensured.

Furthermore, as mentioned above, by combining the appropriate shape or contour and material properties of the wall sections of the clamping jaws, a corresponding preload, preferably adjustably, can be applied to the clamping elements that correspond to one another.

According to a further aspect of the utility model, it may be provided that the first clamping element and/or the second clamping element are formed at least in sections in a plate-like and/or flat shape.

The arrangement of the clamping surfaces, which are preferably used to form the at least one connecting section, in the form of the end faces of the first clamping element and the second clamping element, opposite one another allows a clamping force or pressure to be applied to the electrical conductor in such a configuration, for example at a respective height.

The first clamping element can, for example, also be connected to a wall section of the first clamping jaw, preferably at the end face of the wall section, with the formation of a gap, and/or the second clamping element can be connected to a wall section of the second clamping jaw, preferably at the end face of the wall section, with the formation of a gap or a gap, wherein the gap or gap is preferably configured and/or formed for at least sectionally accommodating or already accommodating a tool guide section for introducing an electrical conductor into the terminal and/or for supporting a tool on the terminal.

The tool guide section can be preferably formed at least in sections in a plate-like and/or flat manner. The tool guide section can be preferably at least partially received or mounted in a form-fitting manner in the terminal.

According to a further aspect of the utility model, it may be provided that the first clamping jaw comprises a further first clamping element and the second clamping jaw comprises a further second clamping element, which correspond to each other and are arranged at least at a distance from each other to form a further clamping slit, wherein the further first clamping element is at least partially in contact with the further second clamping element, so that an effective connection is preferably formed between the further first clamping element and the further second clamping element, similar to what is disclosed herein in relation to the first clamping element and the second clamping element.

The electrical conductor can thereby be connected to the terminal, for example, at two connection sections spaced apart from one another, which results in an optimized electrical contact, for example.

Furthermore, the further first clamping element can be formed at least in sections substantially identically and/or substantially symmetrically to the further second clamping element.

According to a further aspect of the utility model, it may be provided that the first clamping jaw and/or the second clamping jaw preferably have at least one retaining element, preferably at least one projection, on an end face of the first clamping jaw and/or an end face of the second clamping jaw for forming an operative connection with a tool placed on the terminal.

The at least one holding element can, for example, be configured and/or formed in the form of a projection, so that the gripping element or the locking element of the tool can be attached to the projection in order to form a form-and/or force-fitting connection between the terminal and the tool.

The terminals may be formed of a metallic material, preferably integrally, preferably by at least one bending process and/or stamping process.

Another general aspect of the utility model relates to a tool, preferably an installation tool, for connecting a sheathed electrical conductor to a terminal having at least one clamping slot and at least one holding element, preferably to a terminal as described herein, wherein the tool has a guide frame which is arranged opposite the at least one clamping slot in a manner which at least partially matches a first clamping jaw and a second clamping jaw for contacting or securing the terminal, preferably the terminal, and/or is formed, and the tool has a slider unit which is mounted movably on the guide frame for guiding the electrical conductor into the terminal, preferably within the terminal, wherein the guide frame has at least one pivotably mounted locking element and the slider unit is coupled movably on and/or with the at least one locking element for actuating the at least one locking element in order to engage the at least one locking element with the holding element of the terminal at least partially when the conductor is introduced into the terminal, preferably inside the terminal.

Preferably, the tool is configured and/or formed for mounting and/or connecting the electrical conductor to the terminal. The electrical conductor may be formed as a sheathed conductor in the form of a sheathed electrical conductor. The slider unit is preferably mounted in a translatory manner.

A tool is thereby provided, for example, which can keep the mechanical load on the carrier material or carrier structure of the terminal as low as possible or avoid it when connecting the electrical conductor to the terminal. The mechanical load, for example in the form of a force, preferably occurs mainly only inside the tool, the electrical conductor and the terminal.

According to a further aspect of the utility model, it may be provided that the guide frame has at least one cutting element for cutting the sheath of the electrical conductor, preferably by means of a slider unit, at least partially and preferably before the electrical conductor is guided into or inside the terminal, wherein the at least one cutting element is preferably detachably and/or pivotably supported.

Thereby, for example, the cutting depth and/or the cutting angle on the electrical conductor can be varied. Furthermore, the tool can be adapted to different electrical conductors, for example.

At least one cutting element may be configured and shaped, preferably at least partially, to push apart, preferably squeeze apart, the sheath of the electrical conductor at the cutting point or cutting area.

The cutting points or cutting areas may preferably form electrical contact points or electrical contact areas for forming a connection of the electrical conductor with the terminal, i.e. the connection section of the terminal.

In other words, a spot-type or area-type uninsulated electrical conductor for guiding or introducing into the clamping slot of the terminal can preferably be prepared.

According to a further aspect of the utility model, it may be provided that the pivot axis of the at least one cutting element and the pivot axis of the at least one locking element are arranged substantially perpendicular to each other or perpendicular to each other in a view, preferably in a top view.

Detailed Description

Identical or functionally equivalent components or elements are identified in the figures with identical reference numerals. Portions of which are illustrated with reference to other embodiments and/or descriptions of the drawings so as not to be repeated.

The following description of the embodiments illustrated in the drawings is provided for further explanation or illustration and should not be taken as limiting the scope of the utility model in any way.

Fig. 1A shows a front view of an embodiment of a terminal 1 for connecting an electrical conductor 2 with a sheath 20, i.e. for connecting a wrapped electrical conductor 2 (see fig. 1D).

The terminal 1 includes a tab 5 formed in a plate shape. The components and elements of the terminal 1 are arranged or formed on the tab 5, which will be further elucidated below.

A securing plug 23 in the form of a welding pin or a welding pin is arranged on the web 5. The fixing plug 23 is used for mounting or fixing the terminal 1 on a wiring board, a printed circuit board, a circuit card or the like (not drawn in fig. 1B, see, for example, fig. 2A).

The tab 5 also comprises a first jaw 3 and a second jaw 4, each having a respective wall section, as will be further elucidated below.

The first clamping jaw 3 has a first spring-elastic clamping jaw section 24 and is arranged at a distance from the second clamping jaw 4 via a web 5, which likewise has a first spring-elastic clamping jaw section 25. Furthermore, the first clamping jaw 3 is arranged opposite the second clamping jaw 4. This structure can also be seen from the perspective of the terminal 1 in fig. 1C.

The first spring-elastic jaw section 24 of the first jaw 3 is at least partially curved in the direction of the connected or to-be-connected electrical conductor 2 in the illustration shown and is thus optimally shaped in terms of the production process. In other words, the first spring-elastic jaw section 24 of the first jaw 3 extends in a groove-like manner in the direction of the connected or to-be-connected electrical conductor 2 and is connected here to the tab 5, preferably integrally (see perspective view of the terminal 1 in fig. 1C). Accordingly, the same applies to the first spring-elastic jaw section 25 of the second jaw 4.

The first spring-elastic jaw section 24 of the first jaw 3 and the first spring-elastic jaw section 25 of the second jaw 4 present areas of preferably higher elasticity than the other sections of the terminal 1 in order to be able to provide an optimized elastic effect. In this section, a higher elasticity can be achieved, for example, by a corresponding geometric configuration (e.g., smaller wall thickness, curved profile, etc.) and/or by a corresponding material property (e.g., high elastic limit/yield limit).

In the terminal 1 shown in fig. 1A, the first clamping jaw 3 and the second clamping jaw 4 each also have a wall section which is more or less U-shaped or preferably hairpin-shaped as a second spring-elastic clamping jaw section 26, 27, respectively, which is open in the direction of the tab 5. The second spring-elastic jaw sections 26, 27, like the first spring-elastic jaw sections 24, 25, form the elastic elements of the jaws 3, 4, preferably for transmitting and/or applying a force to the clamping elements 7, 8 for the electrical conductor 2 to be clamped, that is to say connected. In other words, the first clamping jaw 3 and the second clamping jaw 4 are characterized by wall sections which are at least partially opposite and/or spaced apart from each other. Co-acting with the first spring-elastic jaw sections 24, 25 allows the elastic properties and effects of the jaws 3 and 4 to be optimized.

This makes it possible, for example, to avoid plastic deformation of the terminal 1 when connecting the electrical conductors 2 having a large cross section and to maintain this state.

The first jaw 3 and the second jaw 4 are formed substantially mirror-symmetrically to each other. As mentioned above, the first clamping jaw 3 and the second clamping jaw 4 are at least partially preferably formed as elastic elements in the form of metal springs and thus have a certain elasticity, preferably a geometric flexibility and/or a material flexibility.

A plate-shaped clamping element 7 is arranged on a wall section of the first clamping jaw 3 located inside or in the terminal 1. A plate-shaped second clamping element 8 is arranged on a wall section of the second clamping jaw 4 located inside or in the terminal 1.

The first clamping element 7 and the second clamping element 8 are formed and arranged at least in sections substantially mirror-symmetrically to each other.

Via the first clamping jaw 3 and the second clamping jaw 4, the first clamping element 7 and the second clamping element 8 are arranged at least partially spaced apart from one another and thereby form the clamping slit 6.

The clamping slit 6 is used for receiving or connecting the electrical conductor 2. The clamping slot 6 has a substantially V-shaped contour in the front view shown in fig. 1A, at least in some sections, that is to say in the inlet region of the clamping slot 6.

This results in the terminal 1, i.e. the first clamping element 7 and/or the second clamping element 8, having at least in sections in the region of the substantially V-shaped contour a cutting edge for at least in sections further cutting the electrical conductor 2.

Furthermore, the first clamping element 7 and the second clamping element 8 are configured, formed and arranged relative to one another in such a way that connection sections 11, 12, 13 for connecting the electrical conductor 2 to the terminal 1 are formed, wherein preferably the electrical conductor 2 is held in the connection sections 11, 12, 13.

In the drawing shown in fig. 1A, the first connection section 11 and the second connection section 12 have a substantially circular or rounded profile. In the drawing shown in fig. 1, the third connecting section 13 is characterized by a substantially elliptical profile.

Furthermore, fig. 1 also shows that the third connecting section 13 has a larger cross section than the first and/or second connecting sections 11 and 12. Thereby, the terminal 1 is able to accommodate electrical conductors 2 of different sizes, i.e. different directivities. Preferably, the terminal 1 can be connected to a terminal having a cross section of at most 35mm ² Is provided. Such an electrical conductor 2 is preferably accommodated in the third connecting section 13.

For receiving or connecting the electrical conductor 2 to the terminal 1, the clamping slit 6 of the terminal 1 is formed by the first clamping element 7 and the first clamping element 8 to be open or accessible from only one direction, i.e. at one end. In other words, the electrical conductor 2 can only be guided into the terminal 1 by the V-shaped section of the clamping slot 6.

The first clamping element 7 is at least partially in contact with the second clamping element 8 at the other end of the clamping slit 6, i.e. the end opposite the V-shaped section of the clamping slit 6, in order to form an effective connection between the first clamping element 7 and the second clamping element 8, preferably by the arrangement and layout of the first clamping jaw 3 and the second clamping jaw 4.

For an effective connection, the first clamping element 7 comprises a projection 9, i.e. a section projecting outwards from the clamping element 7, and the second clamping element 8 has a stop 10, preferably in the form of a cutout.

Via the first clamping jaw 3 and the second clamping jaw 4, the first clamping element 7 and the second clamping element 8 are arranged with a pretension relative to one another and are applied with a pretension. In other words, the first clamping element 7 and the second clamping element 8 form a pressure bond at least partially at the location or area where the protrusion 9 and the stop 10 are in contact.

The effective connection formed at the contact point or contact area between the protrusion 9 and the stop 10 has a number of functions. The operative connection comprises, on the one hand, a pivoting support or pivoting supporting action between the first clamping element 7 and the second clamping element 8. In other words, the clamping slit 6 expands more or less when the electrical conductor 2 is guided into the clamping slit 6. The first clamping element 7 and the second clamping element 8 pivot more or less about the position of the protrusion 9 and the stop 10, i.e. away from each other (see figure 1D with the connected electrical conductor 2).

Furthermore, by the contact of the projection 9 with the stop 10, the effective connection comprises a locking or locking action for the connected electrical conductor 2 located in one of the connection sections 11, 12 or 13, and together with the aforementioned structure of the connection sections 11, 12, 13, prevents an accidental detachment or extraction of the electrical conductor 2 from the terminal 1.

Furthermore, this connection also comprises a stop or stop function for the connected or yet to be connected electrical conductor 2. The contact of the projection 9 with the stop 10 also provides a positive stop for the electrical conductor 2, which prevents, for example, the electrical conductor 2 from accidentally falling out of the clamping slot 6.

Furthermore, the terminal 1 in fig. 1A comprises holding elements 18 in the form of projections, each having a contact surface 19. The holding element 18 with the contact surface 19 serves for receiving or holding a tool 100 for connecting the electrical conductor 2 to the terminal 1 and is explained in more detail with reference to the other figures.

Fig. 1B shows a side view of the embodiment shown in fig. 1A of terminal 1.

It can be seen that the first clamping element 7 and the second clamping element 8 are connected to the first clamping jaw 3 and the second clamping jaw 4, respectively, and that a gap 14 is formed between the first clamping element 7 and the first clamping jaw 3 and between the second clamping element 8 and the second clamping jaw 4. Furthermore, it can be seen from fig. 1B that the first clamping jaw 3 comprises a further first clamping element 16, which is likewise arranged spaced apart from the first clamping jaw 3, forming a recess 15.

The recesses 14 and 15 serve to accommodate sections of the tool 100 (see in particular the subsequent fig. 2A to 3B), which tool serves to establish a connection of the electrical conductor 2 to the terminal 1 (see fig. 2D).

Furthermore, it can be seen from fig. 1B that the two holding elements 18 are formed in the form of a protrusion in the form of a cube and are arranged opposite one another at a distance from one another on the first clamping jaw 3 and are preferably integrally connected in one piece with the first clamping jaw 3.

Furthermore, the direction or extension and position of the electrical conductors to be connected or already connected within the terminal 1 is denoted by "X" in fig. 1B.

Fig. 1C shows a perspective view of the embodiment of the terminal 1 shown in fig. 1A and 1B.

From this figure it is clear that a further second clamping element 17 is located on the second clamping jaw 4. Like the first clamping element 7 and the second clamping element 8, the further first clamping element 16 and the further second clamping element 17 are also formed and arranged substantially mirror-symmetrically to each other and/or are configured and formed in correspondence with the first clamping element 16 and the second clamping element 17.

The further first clamping element 16 and the further second clamping element 17 form, like the first clamping element 7 and the second clamping element 8, connecting sections 11, 12, 13 (not visible in the figures).

Fig. 1C furthermore clearly shows the partially curved and hairpin-shaped wall sections of the first and second spring-elastic jaw sections 24, 25, 26, 27 of the first and second jaws 3, 4 and the protruding holding elements 18 arranged thereon, respectively.

Fig. 1D shows a front view of the embodiment of the terminal 1 shown in fig. 1A to 1C, in which an electrical conductor 2 is connected.

The electrical conductor 2 is designed as a sheath conductor and comprises a sheath 20 (sheath insulation), a filler insulator 21 and strands 22 contained therein. Stranded wire 22 comprises a plurality of individual wires and is preferably made of an electrically conductive material, such as copper or a copper alloy, and is used to connect electrical conductor 2 to terminal 1 to establish an electrically conductive connection.

The electrical conductor 2 has a corresponding or relatively large cross section and is thus accommodated in a substantially oval connecting section 13 in the region of the clamping slot 6 between the corresponding clamping elements 7 and 8 and 16 and 17.

Also clearly visible are the jaws 3 and 4 of the terminal 1 which are "pivoted open" or "pivoted apart" about the projections 9 and the stops 10 by the clamping elements 7 and 8 and the clamping elements 16 and 17. In other words, in order to connect the electrical conductor 2 to the terminal 1, the first and second clamping jaws 3 and 4 are "pivoted" due to the effective connection by forced contact of the protrusions 9 with the stops 10.

The engagement of the projection 9 into the stop 10, i.e. the cutout 10 also provides a stop for the electrical conductor 2, so that it can no longer be pulled out of the terminal 1 easily.

Fig. 2A now shows a perspective view of an embodiment of a tool 100 for establishing a connection of an electrical conductor 20 with a sheath 20 on a terminal 1.

The tool 100 is placed or sleeved on the terminal 1, preferably at least partially on the first jaw 3 and the second jaw 4 of the terminal 1.

The tool 100 may be configured and formed, for example, as a manually operated tool 100 or a robotically operated tool 100.

The tool 100 comprises a guide frame 101. The guide frame 101 has a U-shaped structure with a web region and oppositely disposed leg regions. A slider unit 102 is arranged in the guide frame 101, which is mounted on the guide frame 101 in a movable, preferably translatably movable manner, for guiding the electrical conductor 2 into the terminal 1. The slider unit 102 is actuated by a cylindrical punch element 115. The punch element 115 establishes an operative connection with the slider unit 102 via a through-hole in the web region of the guide frame 101 or is preferably formed as a one-piece part of the slider unit 102. The direction of movement of the punch element 115 and the slider unit 102 is identified by "Y".

On the guide frame 101, i.e. on the leg areas of the guide frame 101, two assembly assemblies 109 are arranged. The mounting assembly 109 can be removably secured to the guide frame 101 or, as in this example, can be integrally connected to the guide frame 101 in one piece (see also the cross-sectional view in fig. 3B). The detachable fastening may be accomplished, for example, by a plurality of bolting. The fitting assembly 109 is formed at least partially in a plate shape.

Cutting tools 116 are provided on each of the assembly assemblies 109, respectively. The cutting tool 116 is detachably connected to the mounting assembly 109 by a plurality of bolting 110 and is thus able to correspondingly position and/or adjust its position and/or orientation relative to the guide frame 101, as described in more detail below.

The cutting tools 116 each comprise two cutting elements 107, which are provided for at least sectionally cutting the electrical conductor 2 before connecting the electrical conductor 2 to the terminal 1. The position of the cutting element 107 on the cutting tool 116 is adapted to the position of the connecting sections 11, 12, 13 of the terminal 1. The cutting tool 116 is formed at least partially in a plate shape.

On each assembly 109 there are also pivotally supported two locking elements 103 in the form of clamping arms, respectively, each having a hook section 106, preferably in the form of a retaining claw. Preferably, the pivotable mounting is realized by means of mounting bolts 111, respectively. The support bolts 111 are cylindrical and are connected, preferably integrally connected, in one piece with the mounting assembly 109.

For actuating the locking element 103, i.e. at least for pivoting the locking element 103 and for grasping the terminal 1 on the holding element 18 of the terminal 1 by means of the locking element 103, the slider unit 102 is further movably mounted or coupled to the locking element 103. The movable coupling is realized here by a rail 104, which is formed on the locking element 103, preferably in one piece.

The slider unit 102 has a guide block 105 in the form of a cylindrical bolt for each locking element 103. The respective guide blocks 105 of the slider units 102 are guided in the slide rails 104 of the respective locking elements 103.

Actuation of the locking element 103 may be achieved by moving the slider unit 102 as described above by the pivotable support of the locking element 103 on the mounting assembly 109 fixed to the guide frame 101 and the coupling between the slider unit 102 formed by the slide rail 104 and the guide block 105 and the locking element 103.

In the arrangement of the tool 100 and the terminal 1 shown in fig. 2A, the electrical conductor 2 is shown in a starting position AP within the tool 100. The locking element 103, which in this state is pivoted out, i.e. pivoted out or turned over from the tool 100, and the electrical conductor 2 accommodated in the tool 100, which is still to be connected to the terminal 1, can be clearly seen.

Actuation of the locking element 103 takes place by the slider unit 102 being moved inside the guide frame 101 in the direction of the end position EP, i.e. in the direction of the connection position of the electrical conductor 2 on the terminal 1 in one of the connection sections 11, 12, 13. The locking elements 103 are gradually pivoted in the direction of the tool 100 and the terminal 1 (see directional arrows on the two locking elements 103 located within the range of the first jaw 3, as shown in fig. 2A).

With further movement of the slider unit 102, the fixing element 18 of the contact terminal 1 is gripped, i.e. contacted, by the hook-shaped section 106 of the locking element 103, preferably contacting the contact surface 19 of the fixing element 18. In addition to the contact of the terminal 1 with the tool at least in sections on the first and second clamping jaws 3 and 4, i.e. on the second spring clamping jaw sections 26, 27, the terminal 1 is also connected to the tool 100 by means of a locking element 103.

In other words, the tool 100 preferably holds the terminal 1 at the contact surface 19 of the holding element 18 by means of the grip element 103, so that a connection of the electrical conductor 2 to the terminal 1 can be made by the guide unit 102.

Furthermore, the electrical conductor 2 is cut at least partially by the cutting tool 116 with its cutting element 107, preferably before the electrical conductor 2 is introduced into the region of the clamping slot 6 of the terminal 1, in order to subsequently connect the electrical conductor 2 to the terminal 1 as previously described.

Since the terminal 1 is fixed by the tool 100, a force flow only occurs within the tool, the electrical conductor 2 and the terminal 1 during the connection of the electrical conductor 2 with the terminal 1. Thus, for example, the introduction of harmful mechanical loads, preferably pressure, into the flat plate 200 of the fixed terminal 1 is avoided. This mechanical loading occurs during assembly, i.e. during the connection of the electrical conductor 2 with the terminal 1. The flat plate 200 can be designed, for example, as a wiring board, printed circuit board or circuit card and is therefore not unnecessarily loaded or damaged by the arrangement of the tool 100 and the terminals 1.

Fig. 2B illustrates another perspective view of the embodiment of the tool 100 illustrated in fig. 2A.

In this figure, the electrical conductor 2 is in a connected position with the terminal 1. In other words, the electrical conductor 2 is guided or preferably pressed from the starting position AP along the clamping slit 6 (see fig. 1A to 1B) to the end position EP, i.e. towards one of the connecting sections 11, 12, 13 (see fig. 1A to 1B), by the slider unit 102. The slider unit 102 is actuated, i.e. moved, by the punch element 115. As previously mentioned, the punch element 115 can be actuated, for example, manually with force or, for example, by means of an adjusting element of a mechanical arm (not shown in fig. 2B).

Furthermore, it is clear from fig. 2B that the locking element 103 is actuated towards the terminal 1 by the slider unit 102 due to its course of movement within the guide frame 101 and due to the pivotable support of the locking element 103 by means of the support bolts and the sliding guidance of the slider unit 102 on the locking element 103. The locking element 103 holds or at least partially grips the terminal 1 at the fixing element 18 of the terminal.

As described above, when the electrical conductor 2 is guided by the slider unit 102 in the clamping slot 6 of the terminal 1 into the desired connection position, i.e. into the desired connection section 11, 12, 13, a closed force flow is formed between the terminal 1, the electrical conductor 2 and the tool 100.

Fig. 2C illustrates a front view of the embodiment of the tool 100 illustrated in fig. 2A and 2B.

As is clear from this figure, the electrical conductor 2 is inserted into the tool 100 in a starting position AP above the pivotably supported cutting element 107 before being connected to the terminal 1.

The section of the slider unit 102 that is in contact with the electrical conductor 2 and guides or presses the electrical conductor into the terminal 1 when the tool 100 has been placed or sleeved has, at least in sections, a substantially circular or curved contour that is substantially identical or at least similar to the outer contour of the electrical conductor 2. This will be described in more detail below.

Fig. 2D shows a top view of the embodiment of the tool 100 shown in fig. 2A to 2C with sections A-A and B-B, which are shown in further fig. 3A and 3B as cross-sectional views.

The view of fig. 2D shows that the two assembly assemblies 109 have a substantially plate-shaped structure at least in sections and are arranged on two opposite outer sides of the bracket area of the guide frame 101.

Furthermore, it can be seen from this view that the cutting element 107 is at least partially wedge-shaped in order to at least partially cut the electrical conductor 2. The two cutting elements 107 are each arranged opposite one another and spaced apart and are preferably rotatably supported on a guide frame 111, i.e. on a cutting tool 116, which is described in more detail below.

Fig. 3A shows a cross-sectional view of the embodiment of the tool 100 shown in fig. 2A to 2D (along section A-A in fig. 2D).

The cutting element 107, which is pivotably mounted on the cylindrical bolt 111, can be clearly seen for cutting the electrical conductor 2, preferably at least partially, before the slider unit 102 guides or inserts the electrical conductor 2 into the terminal 1.

Also easily identifiable is the locking element 103 which is pivotably supported on the mounting assembly 109 by means of a cylindrical bolt 111. The rotation axis of the cutting element 107 and the rotation axis of the locking element 103 are oriented substantially perpendicular to each other.

Fig. 3B shows a cross-sectional view of the embodiment of the tool 100 shown in fig. 2A to 2D (along section B-B in fig. 2D) and a cross-sectional view of the embodiment of the terminal 1 shown in fig. 1A to 1D. In other words, a cross-sectional view of the arrangement of the tool 100 and the terminal 1 is shown.

The tool 100, preferably the guide frame 101 of the tool 100, contacts the terminal 1 with its end face ends, i.e. the end faces of the leg regions, at least in sections, at the first clamping jaw 3 and the second clamping jaw 4 of the terminal.

Furthermore, when the electrical conductor 2 (not shown in fig. 3B) is guided into the terminal 1 and thus into the clamping slot 6, a force flow occurs via the contact points or contact areas. Furthermore, the force transmission takes place via the locking element 103 of the tool 100 which secures the terminal 1 by means of the holding element 18.

The first clamping jaw 3 and the second clamping jaw 4 and the webs 5 of the terminal 1 have a substantially U-shaped structure in this view, wherein the first clamping jaw 3 and the second clamping jaw 4 exhibit leg regions which are connected to one another by a common web 5.

Furthermore, in this figure, a further first clamping element 16 and a further second clamping element 17 and thus a clamping slot 6 of the terminal 1 can be identified.

The cutting tools 116 are each connected to the leg regions of the guide frame 101 by means of a screw connection 110, in this case via a mounting assembly 109, i.e. can be fastened detachably and/or preferably adjustably. In order to adjust and thus orient and position the cutting tool 116 with the cutting element 107, a screw connection 110 of three countersunk screws and one conical head screw is preferably used in this case. Thereby, the cutting tool 116 and the cutting element 107 pivotably mounted thereon are precisely or definably fixed to the guide frame 101.

Furthermore, as can be seen from fig. 3B, a cylindrical punch element 115 is integrally connected or formed with the guide frame 101. Alternatively, the cylindrical stamping element 115 may be fastened to the guide frame 101, for example by means of a detachable screw connection.

Fig. 4A shows a perspective view of the slider unit 102 of the tool 100 shown in fig. 2A to 3B.

In addition to the punch element 115, a conductor guide section 112 of the slider unit 102 for introducing the electrical conductor 2 into the clamping slot 6 of the terminal 1 is also shown. The conductor guide section 112 is formed partially in a plate shape and includes a guide contact surface 114 at an end face end thereof. The guide contact surface 114 is substantially at least partially curved. In other words, the guiding contact surface 114 corresponds more or less to the outer contour modeling of the electrical conductor 2. The guide contact surface 114 is used for guiding or inserting the electrical conductor 2 into the clamping slot 6 of the terminal 1 (see, for example, fig. 1A to 1D).

Furthermore, the slider unit 102 comprises a tool guide section 113. The tool guide section 113 is arranged spaced apart from the conductor guide section 112. They are formed like the conductor guide sections 112 in partial plate form and comprise identical curved surfaces at their end faces for guiding the electrical conductor 2 into possible contact in the clamping slot 6 of the terminal 1.

The tool guide section 113 forms a positive connection by engaging into the recesses 14, 15 of the terminal 1, in order to support the tool 100 at the terminal 1, preferably without play, in the direction of the electrical conductors 2 to be connected.

Fig. 4B shows an enlarged region Z of the slider unit 102 shown in fig. 4A with the locking element 103.

The locking element 103 is pivotably supported on the mounting assembly 109 via a support bolt 111. It can furthermore be clearly seen from fig. 4B that at the beginning of the slide rail 104 on the locking element 103, a guide block 105 is inserted therein in order to subsequently actuate the locking element 103 via the slider unit 102 as described above.

Two guide shoes 105 are arranged opposite each other in the upper region of the conductor guide section 112, i.e. the guide contact surface 114. The guide block 105 has a substantially cylindrical structure in the form of a bolt. The guide blocks 105 are guided in the slide rails 104 of the locking element 103. The slide rail 104 extends at least partially in the direction of the locking element 103 towards the hook-shaped section 106 of the locking element 103.

The guide blocks 105 are arranged spaced apart from a support bolt 111 about which the locking element 103 is pivotably arranged. In other words, as can be seen from fig. 4B, there is an offset between the support bolt 111 of the locking element 103 and the guide block 105 of the slider unit 102 (see also fig. 2B).

The slider unit 102 is coupled with the locking element 103 via a guide block 105 and a slide rail 104, by means of which coupling the movement of the slider unit 102 along the slide rail 104 effects an actuation of the locking element 3 in the form of a pivoting movement. In this case, the hook-shaped section 106 of the locking element 103 moves along the direction of the slide unit 102/along the direction of the tool 100 and thus along the direction of the terminal 1 as a function of the path travelled by the guide block 105 in the slide rail 104 in order to grasp the terminal 1 at the respective holding element 18 and to more or less fix or clip it.

Fig. 5A shows a perspective view of the cutting tool 116 with the cutting element 107 of the embodiment of the tool shown in fig. 2A to 3B.

The cutting tool 116 is at least partially formed in a plate shape and has a more or less triangular contour. The cutting tool 116 is removably secured to the mounting assembly 109 by a bolted connection 110 located at the center of the cutting tool 116 (see also the cross-sectional view of fig. 3B). In addition, the cutting tool 116 has three screw connections 110 arranged in a triangle. This enables adjustability of the position and/or angle and orientation of the cutting tool 116 relative to the mounting assembly 109. As previously mentioned, these screw connections 110 are realized by means of so-called countersunk screws which are supported on the mounting assembly 109 and which, by means of a screw connection 110 located in the center of the cutting tool 116, detachably fix the cutting tool 116 relative to the mounting assembly 109, preferably pressed onto the mounting assembly 109.

For example, the use of the cutting tool 116 enables adjustment of the cutting depth and/or cutting angle depending on the requirements of the terminal 1 and/or the configuration and structure of the electrical conductor 2. Different cross sections and insulation thicknesses of the electrical conductors 2 can be precut and thus different electrical conductors 2.

The cutting tool 116 also includes two cylindrical support bolts 111 that extend outwardly from the cutting tool 116 in opposite directions. The cutting elements 107 are each pivotably and detachably, i.e. interchangeably supported or fixed, on the bearing bolts 111. Thus, differently configured or formed cutting elements 107 can be arranged on the cutting tool 116, for example for different electrical conductors 2. In other words, the tool 100 can thus be individually adapted or configured according to the respective electrical conductor 2.

Furthermore, a coil spring 108 is arranged on each support bolt 111, which applies a prestressing force to the cutting element 107.

Fig. 5B illustrates a perspective view of the cutting element 107 illustrated in fig. 5A.

The cutting element 107 is wedge-shaped and thus comprises, in addition to the cutting edge, a section widened by the cutting edge in order to thereby at least partially push away or push open the cut jacket 20 of the electrical conductor 2 in order to expose the core wire, the individual wire strands or the strands 22 of the electrical conductor 2 and to provide for a connection process of the electrical conductor 2 to the terminal 1.

The present utility model is not limited to the above-described embodiments. On the contrary, numerous variations and modifications are possible using the concepts of the utility model and are therefore within the scope of protection. The utility model preferably also protects the subject matter and features of the dependent claims independently of the claims mentioned.
