Technical Field
[0001] This utility model relates to a cut-type terminal for connecting electrical wires. Background Technology
[0002] This cut-type terminal includes a housing and a contact element having at least one cut-contact section configured to cut into the electrically insulated cable sheath of the conductor for electrical contact. An operating element is adjustablely arranged on the housing and can be operated by a user.
[0003] Such cut-off terminals can be, for example, components of so-called cut-off terminal connectors (also known as IDC connectors, English: Insulator Displacement Connector; also called Insulation-Piercing Contact, or IPC for short).
[0004] Electrical wires are typically connected to cut-to-the-wire terminals by manually or with a tool pressing the wire against a cut contact section of the contact element, thereby cutting the cut contact section into the cable sheath of the wire to make contact. This makes wire connection costly and can make it difficult to reconnect the cut-to-the-wire terminals, i.e., to disconnect and reconnect another wire.
[0005] There is a need for this type of cut-off terminal, which can be connected without tools or can be repeatedly connected in a simple manner.
[0006] An IDC connector is known from DE 10 2005 005 081 B4, wherein a lever element is designed to adjust an electrical contact element so that, under conditions of cutting into a cable sheath, the tips on the contact element make contact with one or more electrical wires.
[0007] Another configuration of IDC connector is known from DE 35 04 823 A1, in which the contact element can be moved by a ratchet. Utility Model Content
[0008] The objective of this invention is to provide a cut-type terminal that, while having a simple structure, enables tool-free connection and repeated connection in a simple manner.
[0009] This task is solved using a type of terminal cutter for connecting electrical wires.
[0010] Therefore, the cutting terminal has an adjustment element that is operatively connected to the operating element. The adjustment element is movable relative to the housing by the user operating the operating element and is configured to act on the electrical conductor so that the conductor moves relative to the housing until it is in contact with at least one cutting contact section.
[0011] In the cut-type terminal, the contact element is arranged statically relative to the housing. For connecting a conductor, the conductor can be placed onto the cut-type terminal, allowing an adjusting element to be operatively connected to the conductor, and the conductor can be moved on the housing by adjusting the adjusting element. Through the action of the adjusting element, the conductor comes into contact with at least one cut contact section of the contact element, such that at least one cut contact section cuts into the cable sheath of the conductor, thereby contacting the internal conductor core.
[0012] The adjustment of the regulating element is achieved by operating the operating element. The operating element can be operated manually by the user or with tools, so that when the user operates the operating element, the regulating element moves on the housing, thereby adjusting the electrical wires.
[0013] The operating element can be operated in particular to adjust the adjusting element so that the conductor can make electrical contact with the contact element through the action of the adjusting element. Conversely, by moving the operating element back, the conductor can also be disengaged from the contact element by adjusting the adjusting element, so as to release the conductor from the contact element and remove it from the cut-off terminal.
[0014] In one design, the adjusting element is movable relative to the housing between an insertion position (in which the conductor can be inserted into the cut-off terminal) and a contact position (in which the conductor is in electrical contact with the contact element). In the insertion position, the conductor can be placed onto the cut-off terminal and connected to the adjusting element. By operating the element, the adjusting element can be moved from the insertion position to the contact position to establish electrical contact between the conductor and the contact element, provided that at least one cut-off contact section cuts into the cable sheath of the conductor.
[0015] In one design, the adjusting element has an inlet opening for guiding an electrical wire into the inlet position. The wire guided into the inlet opening can move relative to the housing by movement of the adjusting element. The inlet opening allows the electrical wire to be guided in. If the electrical wire is guided into the inlet opening, a connection exists between the electrical wire and the adjusting element. If the adjusting element moves relative to the housing by the user operating an operating element, the electrical wire is actuated. In this way, during the movement of the adjusting element from the inlet position to the contact position, the electrical wire makes contact with the contact element under the condition that at least one cut contact section cuts into the cable sheath of the electrical wire. Here, the electrical wire can also be released from the contact element again by moving the adjusting element back to the inlet position, allowing the electrical wire to disengage from the contact element and be removed from the cut terminal.
[0016] In one design, when the adjusting element is in the insertion position, the conductor can be inserted into the insertion opening along the insertion direction. The adjusting element can move from the insertion position to the contact position relative to the housing along an adjusting direction perpendicular to the insertion direction. Therefore, the adjusting element can move linearly on the housing, wherein the adjusting direction (along which the adjusting element can move) is oriented perpendicular to the insertion direction (along which the conductor can be inserted into the insertion opening of the adjusting element). Thus, the insertion of the conductor first occurs along the insertion direction, and then, by operating the operating element, the adjusting element moves on the housing perpendicular to the insertion direction, thereby actuating the conductor to achieve contact with the contact element in such a way that the cable sheath of the conductor is cut into at least one cutting contact section.
[0017] In one design, the adjusting element has a surface segment on which an inlet opening is formed. Specifically, the surface segment can extend in a plane perpendicular to the insertion direction. When the adjusting element is adjusted along the adjusting direction, the surface segment also moves, and thus the inlet opening is adjusted on the housing.
[0018] In one design, the housing has a housing opening, which is at least partially covered by a surface segment, and an inlet opening is adjustable relative to the housing opening during movement of the adjusting element. In the inlet position of the adjusting element, the inlet opening may occupy a first position relative to the housing opening. Conversely, in the contact position, the inlet opening occupies a second position relative to the housing opening. The insertion of the electrical wire is achieved through the housing opening, which, except for the area cleared by the inlet opening, is covered by the surface segment, such that the electrical wire can only be inserted into the inlet opening to connect the electrical wire to the cut-and-switch terminal.
[0019] In one design, the adjusting element has a guide section extending parallel to a surface segment. The surface segment is arranged on a first side of at least one cutting contact segment. Conversely, the guide section is arranged on a second side of at least one cutting contact segment, away from the first side. Thus, the surface segment and the guide section are positioned on different sides of at least one cutting contact segment, such that at least one cutting contact segment is accommodated between the surface segment and the guide section. In this way, the adjusting element can be adjusted and guided on the contact element.
[0020] In one design, the guide section has an opening aligned with the inlet opening for the conductor to pass through. Therefore, when plugged into the cut-off terminal, the conductor is guided into the inlet opening of the face section and also into the opening of the guide section. If the adjusting element then moves on the housing, both the face section and the guide section act on the conductor, causing it to move towards and thus into contact with at least one cut-off contact section. By arranging the face section and the guide section on different sides of the at least one cut-off contact section, the conductor bears the load on both sides of the at least one cut-off contact section, and thus reliably achieves electrical contact with the contact element when the at least one cut-off contact section cuts into the cable sheath of the conductor.
[0021] In one design, the operating element is supported pivotally relative to the housing. The operating element can be designed as a lever, for example, manually operated by the user to move the adjusting element on the housing in this manner. This achieves simple, comfortable, and especially tool-free operation by the user.
[0022] In one design, the interaction between the operating element and the adjusting element is such that the oscillating motion of the operating element is converted into linear motion of the adjusting element relative to the housing. Here, the adjusting element is coupled to the operating element such that the position of the adjusting element depends on the position occupied by the operating element. In the first oscillating position of the operating element, the adjusting element is particularly located in the lead-in position. If the operating element pivots relative to the housing from the first oscillating position to the second oscillating position, the adjusting element moves to the contact position, and thus the lead-in electrical wire makes contact with the contact element.
[0023] In one design, the operating element has a first coupling section. Conversely, the adjusting element has a second coupling section. The first and second coupling sections are coupled to each other to establish an operational connection. The couplings are specifically such that the adjusting element occupies a defined position on the housing, depending on the position of the operating element. The couplings of these sections can be designed, for example, in a form-fit or force-fit manner.
[0024] In one design, the first coupling section has a toothed element structure. The second coupling section, for example, has a structure for the engagement opening of the toothed element. Thus, the first coupling section of the operating element (which is particularly pivotally supported on the housing) achieves an engagement section through the toothed element structure, which engages with the engagement opening of the second coupling section of the adjusting element using the toothed element, thereby establishing a gear-rack coupling in a form of shape fit.
[0025] In one design, the contact element has two cheek elements, each with a cut contact section formed thereon. The contact element can be formed as a single, integral metal part, such as a stamped or bent part. These cheek elements are interconnected, for example, by a base, and each carries the cut contact section.
[0026] For example, these cut contact sections are formed on the curved edges of the cheek element, away from the base. Here, these cut contact sections of the cheek element are oriented relative to each other, so that the conductor can be inserted between these cut contact sections, and thus make electrical contact with the contact element while the cut contact sections cut into the cable sheath of the conductor.
[0027] When viewed in a cross section transverse to the adjustment direction of the adjustment element, the contact element may have a circumferentially closed shape, such as an approximately O-shaped or quadrilateral shape, with the base, the cheek element extending parallel to each other, and the cut contact section formed by the curved edge of the cheek element.
[0028] In one design, gaps exist between the cut contact sections of the cheek element. Here, an adjusting element is configured to act on the conductor so that the conductor moves into the gap and thereby into contact with the cut contact section. The cut contact section extends linearly along the adjusting direction of the adjusting element. Between the cut contact sections, the gap is longitudinally formed along the adjusting direction. For example, when the cut contact sections are open relative to each other, the conductor can be guided into the gap by adjusting the adjusting element to a contact position, such that the cut contact section cuts into the cable sheath of the conductor and thereby makes electrical contact with the conductor's core.
[0029] In order to release the wire from the cut-off terminal, the adjusting element can be moved from the contact position back to the lead position, thereby moving the wire out of the gap and thus disengaging it from the cut contact section, so that the wire can be removed from the cut-off terminal in a substantially effortless manner.

[0046] Figure 1 and Figure 2 An embodiment of a cut-type terminal 1 is shown, which is used to connect an electrical wire 2.
[0047] The cut-type terminal 1 has a housing 10, an operating element 12 pivotally arranged on the housing 10, and an adjusting element 13. The adjusting element 13 can be adjusted relative to the housing 10 along the adjusting direction V and is configured with an inlet opening 130 into which an electrical wire 2 can be inserted for connection to the cut-type terminal 1.
[0048] As this is based on Figure 3 and Figure 4 A view (showing the cut-out terminal 1 without housing 10) and according to Figure 5A , 5B and Figure 6A , 6B As can be seen in the cross-sectional view, the cut-type terminal 1 has a contact element 11, which is formed as a metal part, for example, made of a metal sheet, especially as a stamped and bent part. The contact element 11 has a body 111 with a base 112, and cheek elements 113 are bent relative to the base. These cheek elements 113 form a cut contact section 114 on the bent edge facing away from the base 112. The conductor 2 can make contact with the cut contact section 114 such that the cut contact section 114 cuts into the cable sheath 21, so that the cut contact section 114 makes electrical contact with the conductor core 20 of the conductor 2.
[0049] exist Figure 8A , 8B The operating element 12, shown in a separate view, is constructed as a lever element and is pivotally supported on the housing 10 about the axis of rotation D by means of shaft elements 121 (which are constructed by shaft ends protruding from both sides of the coupling section 122). The user can operate the operating element 12 through the operating section 120 and pivot it relative to the housing along the operating direction B.
[0050] exist Figure 9A , 9B The adjusting element 13, shown in a separate view, is movably supported on the housing 10 along the linear adjusting direction V, and the adjusting element has a coupling section 131 that is coupled to the coupling section 122 of the operating element 12, such that there is an active connection between the operating element 12 and the adjusting element 13, and the adjusting element 13 moves relative to the housing 10 along the adjusting direction V when the operating element 12 pivots.
[0051] An inlet opening 130 is formed on a face section 132 on the front side of the adjusting element 13 and is aligned with an opening 136 in a guide section 133 of the adjusting element 13 that extends parallel to the face section 132. Here, the face section 132 and the guide section 133 are arranged spaced apart from each other, and a cut contact section 114 is accommodated between them at the curved edge on the front side of the cheek element 113 of the contact element 11, such that the adjusting element 13 is guided linearly along the adjusting direction V relative to the cut contact section 114.
[0052] An operational connection is achieved between the operating element 12 and the adjusting element 13 through coupling sections 122 and 131 of the operating element 12 on one hand and the adjusting element 13 on the other hand. Due to this operational connection, the adjusting element 13 moves on the housing 10 when the operating element 12 is operated, wherein the adjusting element 113 occupies a defined position relative to the housing 10 that depends on the position occupied by the operating element 13.
[0053] Specifically, the adjusting element 13 can be operated by the operating element 12, in accordance with... Figure 1 and Figure 3 The location of the import position and the corresponding position based on Figure 2 and Figure 4 The positions of contact are adjusted.
[0054] The coupling section 122 of the operating element 12 has a structure with toothed elements 123 arranged sequentially along a circumferential line around the rotation axis D, and engaging with corresponding engagement openings 134 on the coupling section 131 of the adjusting element 13. By engaging the toothed elements 123 into the engagement openings 134, a gear-rack coupling is achieved between the operating element 12 and the adjusting element 13, thereby converting the oscillating motion of the operating element 12 into linear motion of the adjusting element 13 along the adjusting direction V on the housing 10.
[0055] At the insertion position of adjusting element 13 ( Figure 1 and Figure 3 In this process, the conductor 2 can be inserted into the inlet opening 130 of the surface section 132 and into the opening 136 of the guide section 133, which is aligned with the inlet opening 130, as shown in the image. Figure 5A and Figure 5B As can be seen in the image. Here, the operating element 12 is in the first swing position.
[0056] Then, by pivoting the operating element 12 along the operating direction B, the adjusting element 13 can be moved on the housing 10 along the adjusting direction V, and transferred to the position according to... Figure 2 , Figure 4 , Figure 6A , 6BIn the contact position. At this time, the wire 2, which is introduced into the inlet opening 130 and the opening 136, is driven and thus comes into contact with the cut contact section 114 on the cheek element 113 of the contact element 11.
[0057] As this is based on Figure 7A , 7B As can be seen in a separate view of the contact element 11, these cut contact segments 114 form gaps 116 between each other on the curved edges of the front side of the cheek element 113. When the adjusting element 13 is moved to the contact position, the conductor 2 is pressed into the gaps 116 between the cut contact segments 114, such that the cut contact segments 114 (sharpened on the opposing edges) cut into the cable sheath 21 of the conductor 2 and contact the core wire 20 of the conductor 2. Thus, the conductor 2 is electrically connected to the contact element 11, and therefore to the cut terminal 1.
[0058] If you want to release the wire 2 from the contact element 11 again, then remove the operating element 12 from the contact element 11 according to... Figure 2 , Figure 4 , Figure 6A , 6B The second swing position shifts back to the opposite direction of operation B, according to... Figure 1 , Figure 3 , Figure 5A , 5B In the first swing position, the adjusting element 13 is thus moved upward on the housing 10 in the opposite direction of adjustment V. Here, the wire 2 is driven and thus removed from the slot 116 and disengaged from the cutting contact section 140. Therefore, the wire 2 can be removed (again) from the cutting terminal 1.
[0059] The face section 132 and the guide section 133 accommodate the cutting contact section 114 between them, and are therefore linearly guided along the adjustment direction V at the cutting contact section 114. Here, an abutment edge 135 is formed between the face section 132 and the guide section 133, which serves as a stop to define the adjustment path of the adjusting element 13 relative to the contact element 11 along the adjustment direction V. Figure 6A , 6B In the contact position, the abutting edge 135 and the upper edge 115 of the cutting contact section 114 are in contact, so that the adjusting element 13 occupies a limited position relative to the cutting contact section 114.
[0060] The housing 10 has a housing opening 100, as shown in this... Figure 1 and Figure 2As can be seen, the wire 2 can be inserted into the housing 10 through the housing opening. The surface segment 132 extends in the region of the housing opening 100 and covers the housing opening 100, such that the housing opening 100 is only open in the region of the inlet opening 130, and the wire 2 can only be inserted into the inlet opening 130.
[0061] By adjusting element 13 at the inlet position ( Figure 1 ) and contact position ( Figure 2 Adjustments are made between the two openings, and the position of the inlet opening 130 relative to the housing opening 100 is changed.
[0062] The wire 2 can typically be inserted into the cut-off terminal 1 along the insertion direction E. Here, the adjustment direction V of the adjustment element 13 is oriented perpendicular to the insertion direction E. If the wire 2 is inserted into the inlet opening 130, and if the adjustment element 13 moves on the housing 10 along the adjustment direction V, then the wire 2 is driven along the adjustment direction V and thus deflects on the housing 10 perpendicular to the insertion direction E.
[0063] If the conductor 2, after being inserted into the inlet opening 130, is pressed into the gap 116 between the cut contact sections 114 when the adjusting element 13 is moved to the contact position, then the adjusting element 113 opens in a plane perpendicular to the adjusting direction V. Thus, the contact element 11 is elastically tensioned, such that the cut contact sections 114, under the condition that the cable sheath 21 of the conductor 2 is cut into, make contact with the core wire 20 using elastic tension.
[0064] In the illustrated embodiment, the contact element 11 has a connecting pin, which may provide, for example, a contact for plugging into a connection device, such as an IDC connector, or it may be used for electrical connection to a corresponding electrical component, such as a circuit board.
[0065] The ideas underlying this invention are not limited to the foregoing embodiments, but can also be implemented in other ways.
[0066] In the illustrated embodiment, the operating element is pivotally supported on the housing. However, it is also possible for the operating element to move relative to the housing in other ways, such as linearly or along a tortuous path.
[0067] The operating element can be directly supported on the housing, or supported on a component that is stationary relative to the housing, such as on a contact element.
[0068] By activating the operating element and the adjusting element, and by allowing the adjusting element to move on the housing through operation of the operating element in order to act on the electrical wire, the cut-type terminal enables tool-free manipulation and simple control for connecting electrical wires and for repeatedly switching on and off electrical wires.
