Description
Technical Field
[0001] This utility model relates to a terminal block for connecting electrical wires. Background Technology
[0002] This type of terminal block includes: a housing having a plug opening; a contact element disposed on the housing having a contact section for electrical contact with a wire inserted into the plug opening; and a spring element. The spring element has a clamping leg, a bent connecting section, and a contact leg connected to the clamping leg via the connecting section for supporting the spring element relative to the housing. The clamping leg is configured to act on the wire inserted into the plug opening in a clamped position to bring the wire into contact with the contact section of the contact element, and the clamping leg can be adjusted from the clamped position to a released position to release the inserted wire. An actuating element is movable relative to the housing to adjust the clamping leg from the clamped position toward the released position.
[0003] This type of terminal block is implemented as a spring connector by using a spring element, wherein the electrical wire is clamped to the contact section of the contact element by clamping legs in the wired state, and thereby electrically connected to the contact element, and is also mechanically locked to the terminal block.
[0004] The spring element is supported relative to the housing by the abutment leg, while the clamping leg can elastically deflect relative to the abutment leg to apply an elastic clamping force to the inserted wire in the clamped position, thereby clamping the wire to the contact section of the contact element. Upon transition to the release position, the spring element is elastically tensioned, with deformation occurring particularly in the area of the bent connection section.
[0005] A terminal block is known from EP 3 772 777 A1, which is implemented as a spring connector and for this purpose has a spring element having a clamping leg and a supporting leg supported on a housing. The clamping leg is connected to the supporting leg via a bent connecting section. The connecting section extends around a bolt-shaped housing section and provides a bending radius for the elastic deflection of the clamping leg relative to the supporting leg. An actuating element, consisting of a pressing element, is configured to act on the clamping leg to thereby adjust the clamping leg relative to the supporting leg and tension the spring element.
[0006] Other terminal block designs are known, for example, from DE 10 2010 025 930 B4 and DE 10 2015 104 625 B4, which have clamping legs that are adjustable by a control element.
[0007] In terminal blocks implemented as spring-loaded connectors, especially in the area where bending deformation occurs in the connection section between the clamping leg and the abutment leg, the clamping leg can elastically deflect relative to the abutment leg. In typical terminal blocks, an actuating element is engaged with the clamping leg for this purpose, so that, under elastic tension of the spring element, the clamping leg can be adjusted towards the release position by the force acting on the clamping leg. In order to achieve the force acting on the clamping leg, for example in the case of an actuating element implemented by a lever and oscillatingly supported relative to the housing, the actuating element and the clamping leg are usually designed such that there is an active connection between the actuating element and the clamping leg. This can complicate the structure of the terminal block and also come with non-negligible structural space requirements. Utility Model Content
[0008] The objective of this invention is to provide a terminal block that, with a simple design, space-saving features, and low cost, enables adjustment of a spring element via a control element.
[0009] This task is solved by a subject matter having the features of this invention.
[0010] Accordingly, the actuating element has an operating section, and a connecting section surrounds the operating section such that when the actuating element moves, the operating section drives the connecting section, thereby adjusting the clamping leg from the clamping position toward the releasing position.
[0011] The clamping legs are designed to clamp the conductor inserted into the socket opening of the housing in the clamped position, so as to push or pull the conductor against the contact section of the contact element. By adjusting from the clamped position to the released position, the receiving space inside the housing aligned with the socket opening is released, allowing the wire to be inserted into the socket opening in a substantially unforced manner for connection to the terminal block, or allowing the inserted wire to be removed from the socket opening in a substantially unforced manner.
[0012] The adjustment of the clamping legs toward the release position is achieved by an operating element that can be operated by the user and moved relative to the housing of the terminal block. However, the operating element does not act directly on the clamping legs during operation, but rather acts on a connecting section that surrounds the operating section, thereby adjusting the clamping legs to the release position through the force applied to the connecting section.
[0013] Compared to terminals that (directly) move the clamping legs towards the release position via an actuating element, the proposed terminal implements a different concept, in which the actuating element does not act directly on the clamping legs. Instead, the tensioning of the spring element to move the clamping legs to the release position is achieved through a force acting on the connecting section. Due to the force acting on the connecting section, the clamping legs are indirectly adjusted relative to the housing and thus moved to the release position, without the actuating element acting directly on the clamping legs.
[0014] Because the operating element operates at the connection section, the terminal block can be made very small. Furthermore, for example, standard springs can be used for spring elements without requiring special adaptation.
[0015] In one design, the housing has a support section on which the clamping legs are supported when adjusted to the release position. The support section is rigidly formed on the housing and provides support for the clamping legs relative to the housing when force is applied to the connecting section by an actuating element. The support section, for example, has a rounded, particularly (partially) cylindrical shape and provides a resting portion for supporting the clamping legs.
[0016] In one design, the clamping leg is supported on the support section at a position between the connecting section and the free end of the clamping leg, which has clamping edges. The clamping leg extends from the connecting section with its free end having clamping edges. In the clamped position, the clamping leg acts on the inserted wire through the clamping edges. In the position between the connecting section and the clamping edges, the clamping leg rests against the support section and is thus supported relative to the housing, so that the clamping leg can be adjusted towards the release position when a force is applied to the connecting section by an actuating element.
[0017] In one design, the actuating element is configured to tilt the connecting section relative to the support section, thereby adjusting the clamping leg to the release position. The connecting section is curved and provides a radius of curvature between the abutment leg and the clamping leg. However, the connecting section is not fixedly supported relative to the housing, but rather tilted relative to the housing by the action of the actuating element, thereby actuating the clamping leg and adjusting it toward the release position.
[0018] In particular, the spring element can be designed such that the central axis (around which the connecting section bends) is not held in a fixed position relative to the housing when the spring element is adjusted, but is adjusted relative to the housing by the force applied at the connecting section.
[0019] In one design, the connecting section is elastically deformable when the clamping leg is adjusted to the release position. By applying force to the connecting section using an actuating element, the position of the abutment leg relative to the clamping leg changes, bringing the abutment leg and clamping leg closer together. Consequently, the spring element is tensioned, particularly in the region of the connecting section, due to the elastic deformation. Specifically, the radius of curvature on the connecting section changes, causing the connecting section to contract due to elastic deformation as the clamping leg moves to the release position. Therefore, by acting on the connecting section, the actuating element induces elastic deformation, which results in the tension of the spring element when the clamping leg moves to the release position.
[0020] For example, the connecting section has a first radius of curvature in the clamping position of the clamping leg. In contrast, in the released position of the clamping leg, the connecting section has a second radius of curvature that is smaller than the first radius of curvature. Therefore, when adjusting towards the released position, the radius of curvature decreases, causing the connecting section (with respect to its internal width) to narrow and shrink.
[0021] The operating element can be operated by the user with a tool, such as a screwdriver, or without a tool, such as with a finger, so that it can act on the connecting section and thereby adjust the clamping leg from the clamping position to the releasing position.
[0022] The actuating element can be adjusted relative to the housing in any way. For example, the actuating element can be configured as a pivotable lever or as a pressing element that can move relative to the housing.
[0023] In one design, the actuating element is oscillating relative to the housing from an unoperated position to an operated position to adjust the clamping leg to a released position. Therefore, the actuating element can pivot relative to the housing to act on the connecting section of the spring element and adjust the clamping leg to the released position. The operated position corresponds to the released position of the clamping leg. When the actuating element is in the operated position, the clamping leg is correspondingly in the released position.
[0024] In one design, the actuating element has a lever section that can be operated by a user. The lever section can be accessed specifically from outside the housing, allowing the user to act on the lever section with or without tools to move the actuating element relative to the housing.
[0025] In one design, the actuating element has at least one support leg housed within a support space of the housing, the support leg preferably being buoyantly supported within the support space. A support profile can be formed on the support leg, for example, designed to interact with a mating profile on the housing that defines the support space, in order to provide support for the actuating element on the housing. The support leg can, for example, be positioned with a gap in the support space, such that the support leg is buoyantly supported within the support space.
[0026] In one design, the actuating element has two support legs extending parallel to each other. The actuating section preferably extends between the support legs, such that a spring element surrounds the actuating section with a connecting section and is inserted between the support legs.
[0027] In one design, the actuating section can rotate within the connecting section when the actuating element pivots. If the actuating element pivots relative to the housing to adjust the clamping legs toward the release position, the actuating section twists within the connecting section, wherein the actuating section changes its position relative to the housing in such a way that the connecting section is driven, and thereby the clamping legs are adjusted toward the release position.
[0028] In one design, the actuating element is capable of swinging relative to the housing about a support axis. The support axis can be defined, for example, by the support of at least one support leg in the housing, within a provided support space, wherein, in the case of a floating support leg, the position of the support axis can be varied within a certain distance (with respect to a plane perpendicular to the support axis) if necessary.
[0029] The central axis (around which the connecting section bends) is preferably arranged eccentrically relative to the support axis. The connecting section has an arcuate shape in a cross-section transverse to the central axis, wherein the connecting section may, for example, be circumscribed by an angle greater than 145°, preferably greater than 180°. The actuating section is arranged, for example, at least approximately concentrically with the central axis. Because the central axis is eccentrically arranged relative to the support axis of the actuating element, the position of the central axis changes when the actuating element pivots relative to the housing. Due to the change in the position of the central axis, the connecting section is adjusted when the actuating element pivots relative to the housing, thereby causing the clamping leg to move relative to the housing, and being brought toward the release position when the actuating element moves to the actuating position.
[0030] In one design, the connecting section is configured such that, in the released position of the clamping leg, a torque is generated on the operating element in the direction of the operating element's operating position. When the clamping leg moves to the released position, the spring element is tensioned. Therefore, in the clamping position of the clamping leg, an elastic tension force exists on the spring element. This tension force induces a relative force between the connecting section and the operating section of the operating element. This relative force can be designed such that it induces a torque on the operating element in the clamping position of the clamping leg, the torque pointing in the direction of the operating position. Therefore, the operating element is loaded in the direction of the operating position and thus held in the operating position. If the operating element is adjusted to the operating position to move the clamping leg to the clamping position, then when the user no longer engages the operating element, the operating element does not automatically reset, but is held in the operating position due to the force between the tensioned spring element and the operating element.
[0031] If the control element is adjusted back from the control position to the uncontrolled position, it can exceed the stop point at a certain adjustment angle. From this stop point, the direction of the torque acting between the spring element and the control element is reversed, so that the further pivoting movement of the control element towards the uncontrolled position is supported by the tension of the spring element.
[0032] In one design, when adjusting the clamping legs, the abutment legs can move relative to a section that is fixed in position relative to the housing. Specifically, the abutment legs are not fixed in position relative to the housing, but rather can move relative to this fixed section when the clamping legs of the spring element are adjusted. If the clamping legs move from the clamping position to the released position, and if the spring element is thus tensioned, then the abutment legs can move relative to the fixed section of the housing, and therefore compensating movement can be performed relative to this fixed section.
[0033] When the clamping leg is adjusted to the release position, deformation occurs, particularly in the area of the connecting section of the spring element. Because the abutment leg can move relative to the section whose position is fixed relative to the housing, the spring element can perform compensating movement within the housing to adjust the clamping leg relative to the abutment leg under elastic deformation at the connecting section, while conveniently and effortlessly introducing force into the spring element, especially to improve insertion and removal safety.
[0034] In one design, the abutment leg has a stop element that occupies a first position in the clamping position of the clamping leg, relative to a segment fixed in position relative to the opposing housing, and a second position in the released position of the clamping leg, the second position being closer to the segment fixed in position relative to the opposing housing compared to the first position. The stop element can be formed, in particular, on the end of the abutment leg away from the connecting segment. For example, the stop element can be formed by bending a ridge on the end of the abutment leg. In the clamping position of the clamping leg, the stop element is away from the segment fixed in position relative to the opposing housing, while in the released position of the clamping leg, i.e., when the spring element is tensioned, the stop element is closer to the segment fixed in position relative to the opposing housing.
[0035] In particular, the stop element can abut against the section fixed relative to the housing in the released position of the clamping leg. Therefore, the stop element restricts the movement path of the abutting leg in such a way that, when the clamping leg moves to the released position, the stop element abuts against the section fixed relative to the housing, thus preventing the abutting leg from having any further movement path relative to the section fixed relative to the housing.
[0036] In one design, the contact element has a support section. The contact element can be formed, for example, as a bent sheet metal element. The support section can, for example, extend (at least approximately) parallel to the contact section. An inserted electrical wire is clamped against the contact section by a clamping leg of a spring element, thereby making electrical contact with the contact section, while the clamping leg is supported on the support section.
[0037] The support section of the contact element is preferably constructed as a section whose position is fixed relative to the housing.
[0038] For example, the abutment leg can slide on the support section. The abutment leg thus abuts against the support section. The abutment leg is slidably supported on the support section (which is fixed in position relative to the housing) and is able to move relative to the support section.
[0039] The type of terminal block described can be used in various ways, such as on terminal blocks, plug connectors, or as a wiring section on a circuit board. Attached Figure Description

[0050] Figure 1A , 1B Embodiments 1, 2A, and 2B illustrate a terminal block 1 having a housing 10, a contact element 11 fixedly arranged on the housing 10, a spring element 12, and an actuating element 14.
[0051] The housing 10 is configured with a plug-in opening 100 into which the electrical wire 2 can be inserted (with the insulation stripped) at the wire end 20 along the plug-in direction E. A spring element 12 is located in a receiving space 101 within the housing 10. This spring element extends into the receiving space 101 in a region aligned with the plug-in opening 100 such that the inserted electrical wire 2 can be clamped by the clamping leg 120 to the contact section 110 of the contact element 11, so as to make electrical contact between the electrical wire 2 and the contact section 110, and further mechanically locked onto the terminal 1.
[0052] exist Figures 3A-3C The spring element 12, shown in a separate view, has a contact leg 121 connected to the clamping leg 120 via a bent connecting section 122. The clamping leg 120 is resiliently deflectable relative to the contact leg 121 to deflect the clamping leg 120 from... Figure 1A , 1B The clamping position shown is towards Figure 2A , 2B The direction adjustment of the release position is shown.
[0053] exist Figures 4A-4CThe actuating element 14, shown in a separate view, is located in the actuating opening 102 of the housing 10 and is pivotable relative to the housing 10 along the actuating direction B. The actuating element 14 has a lever section 140 that is accessible from outside the housing 10 and can be operated by a user with or without a tool, such as a screwdriver.
[0054] The actuating element 14 is pivotally supported on the housing 10. To support the actuating element 14 on the housing 10, the actuating element 14 has two support legs 142 located in the support space 105 of the housing 10, and has an arcuate support profile 143 constructed around the support axis L, which interacts with the protruding section 106 on the housing 10 that defines the support space 105 in a sliding manner.
[0055] If necessary, the actuating element 14 can be floatingly supported in the support space 105 in such a way that the actuating element 14 is inserted into the support space 105 with a certain gap via the support leg 142. Therefore, the position of the support axis L (about which the actuating element 14 can pivot) can be varied within a certain distance (about a plane perpendicular to the support axis L) if necessary.
[0056] An actuating section 141 extends between the support legs 142, and the spring element 12 surrounds this actuating section with a connecting section 122. The actuating element 14 is connected to the spring element 12 via the actuating section 141 and the connecting section 122, such that the actuating element 14 is in the unoperated position (…). Figure 1A , 1B ) and manipulation position ( Figure 2A , 2B When the spring element 12 pivots between the two parts, it drives the connecting section 122, thereby adjusting the spring element 12 relative to the housing 10.
[0057] exist Figures 5A-5C The contact element 11, shown in a separate view, is constructed as a bent sheet metal element, particularly as a stamped and bent piece made of metal. The contact element 11 has a support section 111 that extends at least approximately parallel to the contact section 110. Not only the contact section 110 but also the support section 111 is bent at approximately 90° relative to the bottom 112 of the contact element 11. Extending from the contact section 110 is a pin-shaped wiring element in the form of a lead 113, through which the terminal 1 can be arranged, for example, on a circuit board.
[0058] The housing components of the housing 10 are constructed in separate views. Figures 6A-6C As shown in the figure, and can be accessed through Figures 7A-7C The housing cover 104 shown is closed to complete the housing 10. According to... Figures 6A-6CTogether with the housing components of 7A-7C, they form the support space 105 inside the housing 10. A raised section 106 is formed on each of the two housing components, which defines the support space 105 in a plane perpendicular to the support axis L, and thereby provides support for the support leg 142 within the housing 10.
[0059] According to Figure 2A , 2B In the released position, the clamping leg 120 is deflected relative to the abutment leg 121 such that the area within the receiving space 101 aligned with the insertion opening 100 is released, and thus the electrical wire 2 can be inserted into the insertion opening 100 without obstruction by the clamping leg 120 in order to contact the contact element 11.
[0060] If the operating element 14 is adjusted back to the unoperated position after the wire 2 is inserted, the clamping leg 120 abuts against the wire 2 due to the elastic tension at the spring element 11 and clamps the wire 2 with the contact section 110, thereby making the wire 2 electrically contact the contact section 110 and, in addition, mechanically locking it at the terminal 1.
[0061] In the illustrated embodiment, the spring element 12 is floatingly housed and supported within the housing 10.
[0062] The spring element 12's abutment leg 121 rests on and slidably abuts against the support section 111 of the contact element 11, while the clamping leg 120 rests on the support section 103 rigidly formed in the housing 10. The connecting section 122 extends around the actuating section 141 of the actuating element 14, wherein, at least in the clamped position, a gap may exist between the connecting section 122 and the actuating section 141.
[0063] In order to make the clamping leg 120 of the spring element 12 from according to Figure 1A , 1B The clamping position is transferred to according to Figure 2A , 2B In the released position, the user can act on the lever section 140 of the operating element 14, thereby pivoting the operating element 14 relative to the housing 10 in the operating direction B. Thus, the operating element 14 acts on the connecting section 122 of the spring element 12 with its acting section 141, and tensions the spring element 12 within the housing 10. Consequently, due to the tension of the spring element 12 and the accompanying change in its position within the housing 10, the clamping leg 120 moves from the clamping position to the released position.
[0064] According to Figure 2A , 2BIn the released position, the clamping edge 123 formed on the free end of the clamping leg 120 is away from the contact section 110 of the contact element 11, as this is from Figure 2A , 2B As can be seen in the diagram, the wire 2 can be introduced into the intermediate space between the clamping leg 120 and the contact section 110 with the wire end 20 having its insulation stripped, so that after the operation of the operating element 14 is canceled, the wire 2 can be clamped by the clamping leg 120 and the contact section 110.
[0065] When operated by the user, the operating element 14 moves the connecting section 122 to adjust the spring element 12. This causes the connecting section 122 to tilt relative to the support section 103 within the housing 10. This changes the position of the central planes E1 and E2 pointing through the central axis Z, by adjusting the connecting section 122 in the clamped position (…). Figure 1A , 1B The center plane E1 in the ) tilts along the tilt direction K to the center plane E2 in the release position. Figure 2A , 2B Accordingly, the position of the central axis Z of the connecting section 122 (around which the connecting section 122 bends) also changes.
[0066] As from Figure 1A and 2A As can be seen, the central axis Z (around which the connecting section 122 curves in an arc) is arranged eccentrically relative to the support axis L. Therefore, in a plane perpendicular to both the central axis Z and the support axis L, the central axis Z and the support axis L are spaced apart.
[0067] Furthermore, the functional section 141 is eccentrically arranged relative to the support axis L. The functional section 141 is arranged at least approximately concentrically with the central axis Z.
[0068] Due to the eccentricity of the central axis Z and the actuating section 141 relative to the supporting axis 141, when the actuating element 14 pivots, the actuating section 141 moves about the supporting axis L, thereby driving the connecting section 122. Therefore, under the condition that the actuating section 141 twists within the connecting section 122, the connecting section 122 changes its position within the housing 10, as this occurs from... Figures 1A to 2A As can be seen in the transition.
[0069] When adjusting the spring element 12 to pivot the clamping leg 120 to the release position, under elastic deformation, the abutment leg 121 and the clamping leg 120 come close to each other, especially in the area of the connecting section 122, as this occurs when... Figure 1A , 1B arrive Figure 2A , 2BAs can be seen in the transition. The connecting section 122 is correspondingly shortened, and due to the increased curvature, the radius of curvature of the connecting section 122 (measured relative to the central axis Z) becomes smaller.
[0070] Due to the positional change of the connecting section 122 and the tension of the spring element 12, the clamping leg 122 pivots about the rigid support section 103 and is thus adjusted to the release position, as this is from Figure 2A , 2B As can be seen in the text.
[0071] According to Figure 2A , 2B In the released position, the connecting section 122 induces a torque on the actuating element 14, the torque pointing in the actuating direction B, thereby loading the actuating element 14 toward the actuating position. Because the spring element 12 is tensioned in the released position of the clamping leg 120, a force acts between the connecting section 122 and the actuating section 141. Here, this force is oriented such that the torque generated around the support axis L points in the actuating direction B. Therefore, the actuating element 14 is held according to... Figure 2A , 2B It is in the operating position and does not automatically adjust back to its original position.
[0072] In order to make the spring element 12 from according to Figure 2A , 2B The clamping leg 120 is reset to the release position according to Figure 1A , 1B In the clamped position, the user must actively pivot the operating element 14 relative to the housing 10 in the opposite direction of operation B. Here, at a certain swing angle, it exceeds the stop point, from which point the torque direction is reversed due to the force between the operating section 141 and the connecting section 122, and thus the (further) adjustment of the operating element 14 to the unoperated position is supported by the spring force of the spring element 12.
[0073] The abutment leg 121 abuts against the support section 111 of the contact element 11 and is movable relative to the housing 10 at the support section 111 and thereby. A stop element 124 is formed at the end of the abutment leg 121 away from the connection section 122. The stop element 124 is constructed from the bent edge of the abutment leg 121 and limits the movement distance of the abutment leg 121 relative to the support section 111.
[0074] Since the connecting section 122 is slidably supported on the support section 111, when the spring element 12 deforms in an elastic bending manner, the stop element 124 formed on the abutment leg 121 moves relative to the support section 111 in the direction X such that the stop element 124 at the end of the abutment leg 121 approaches the support section 111, and according to Figure 2A, 2B The release position is close to the support section 111.
[0075] If the wire 2 is to be connected to the terminal 1, the clamping leg 120 is moved according to the operation of the operating element 14. Figure 2A , 2B In the released position. After the operating element 14 is reset, the clamping leg 120 clamps the wire 2 to the contact section 110 of the contact element 11, and thus connects the wire 2 to the terminal 1.
[0076] If the wire 2 is to be removed from the terminal 1, the operating element 14 can be pivoted in the operating direction B to release the clamping leg 120 from the wire 2 and thus release the wire 2 from the plug opening 100 in order to remove it.
[0077] In the illustrated embodiment, the actuating element 14 is constructed from a swingable lever element that can move on the housing 10. In another design, the actuating element 14 is movable relative to the housing 10.
[0078] The ideas underlying this invention are not limited to the aforementioned embodiments, but can also be implemented in other ways.
[0079] The type of terminal block described can be applied, for example, to plug-in connectors, terminal blocks or other arbitrary electrical components, such as circuit boards.
