Description

Technical Field

[0001] This invention relates to a terminal block having an insulating material housing, wherein the terminal block is configured as a multi-pole terminal block, the multi-pole terminal block having a plurality of spring-loaded clamping connectors disposed within the insulating material housing, wherein the insulating material housing has a wire inlet opening associated with each spring-loaded clamping connector, through which a wire can be introduced into the insulating material housing in a wire inlet direction and clamped at the associated spring-loaded clamping connector by means of spring force, wherein the spring-loaded clamping connector has at least one busbar and a clamping spring, the clamping spring having clamping legs, the clamping legs having clamping edges for clamping the wire at a clamping location at a contact section of the busbar, wherein the terminal block has at least one actuating element, the clamping legs being movable to an open position by means of the actuating element when the manual actuating section of the actuating element is manually actuated. Background Technology

[0002] Such a terminal block is known from DE 10 2020 119 372 A1. This relates to a terminal block that automatically connects to the conductor to be clamped when the conductor is inserted into it. Upon insertion of the conductor, the clamping legs of the clamping spring, which are held in the open position, automatically release, thereby causing the conductor to be firmly clamped. Summary of the Invention

[0003] Therefore, the purpose of this invention is to propose a further improved terminal block.

[0004] The objective is achieved by disposing of at least one actuating element between two adjacent wire inlet openings. This allows the actuating element to be integrated into the terminal block with very little space. Consequently, existing and proven terminal block structures, particularly those constructed without actuating elements, can be improved with minimal cost and without a completely new structure, into terminal blocks with actuating elements for operating the clamping legs.

[0005] The present invention is suitable, for example, for compact junction box terminals, such as junction box terminals with leaf spring connectors, wherein the clamping leg is connected to the support section of the clamping spring without the spring bow known in many junction box terminals, which extends over an angular range of greater than 180°.

[0006] According to an advantageous design of the invention, at least one actuating element is configured as a pivotable lever or a movable pressing member. The pivotable lever allows the clamping leg to be moved to an open position by means of a pivoting movement, while the movable pressing member allows the clamping leg to be moved to the open position by means of a traversing movement. This enables a wide range of feasible implementations and integration possibilities for the actuating element in existing terminal block structures. If the terminal block has multiple actuating elements, these elements can be uniformly configured as either pivotable levers or movable pressing members. Alternatively, the actuating elements can be configured differently, for example, partially as levers and partially as pressing members.

[0007] The insulating housing may have a partition wall formed of the insulating housing material between two adjacent wire inlet openings. The partition wall may extend into the interior of the insulating housing to the spring-clamping connector, separating the spring-clamping connectors from each other, thus ensuring that electrical wires introduced through the wire inlet openings can only be selectively connected to the spring-clamping connector associated with that wire inlet opening. If such a partition wall is present, the actuating element may extend parallel to the partition wall. For example, the actuating element may be directly disposed at or abut against the partition wall.

[0008] According to an advantageous design of the invention, at least one actuating element disposed between adjacent wire entry openings simultaneously forms a partition wall between the adjacent wire entry openings. In this manner, space savings can be further optimized, as the previously described partition wall of the insulating material housing can be completely or at least partially eliminated. The partition wall is then replaced by the actuating element disposed between the adjacent wire entry openings. The actuating element can here be made of an insulating material, for example, of the same material as the insulating material housing or of another material, particularly plastic.

[0009] According to an advantageous design of the invention, exactly one clamping spring can be operated by at least one actuating element, or multiple clamping springs, particularly two adjacent clamping springs, can be operated by at least one actuating element. Here, the actuating element is advantageously positioned between two adjacent clamping springs. This also enables multiple implementations of the terminal block. When the actuating element is configured to operate multiple clamping springs, so many actuating elements are not required in the terminal block, further reducing the space required. In this case, the insulating housing may have, for example, a partition wall between adjacent wire inlet openings, and no actuating element is positioned between these openings.

[0010] According to an advantageous design of the invention, at least one operating element can be manually operated at a manual operating section on the housing side of the insulating material housing, where an electrical wire can be introduced into a corresponding wire inlet opening. Correspondingly, the operating element can advantageously be manually operated at the wire inlet side of the insulating material housing. If the electrical wire is already clamped at the clamping point, manual operation of the operating element is prevented by the portion of the electrical wire extending from the insulating material housing, thereby reducing the possibility of erroneous operation of the operating element.

[0011] According to an advantageous design of the invention, when the electrical wires are connected in the terminals, the manual operating section is located between adjacent connected electrical wires. This also reduces the possibility of erroneous operation of the manual operating element.

[0012] According to an advantageous design of the invention, the terminal block has a retaining element configured to hold the clamping legs in the open position. The retaining element also holds the clamping legs in the open position when no manual force is applied to the actuating element. This configuration allows for the integration of automatic release technology into spring-forced clamping connectors and terminals of various structural forms. In particular, reliable terminal blocks of known structural types can be extended to automatic release functionality, i.e., automatic wire connection of the clamped conductor, in this manner with minimal cost.

[0013] The retaining element can be movably configured, for example, movably, pivotally, or otherwise deflectably configured, such that the retaining element can be slightly deflected by an inserted wire to achieve a desired release effect between the clamping leg and the retaining element. The retaining element can be movably supported, for example, movably supported along a straight or arcuate direction. The retaining element can be pivotally supported. In this case, the retaining element can pivot about a fixed or variable pivot axis. In the case of a variable pivot axis, the retaining element can, for example, be floatably pivotally supported. The retaining element can also perform a combination of lateral and pivotal movements. The retaining element can also be otherwise movably supported such that the retaining element can be deflected sufficiently far to release the clamping leg's latch at the retaining element.

[0014] By means of an actuating element, the clamping leg can be moved to the open position by overcoming the spring force of the clamping spring during manual operation. In the open position, the clamping leg can then be held by a retaining element, and the actuating mechanism can be easily operated manually, making it feasible to introduce electrical wires at any time without requiring special force. For example, the clamping leg can be locked at the retaining element in the open position.

[0015] The clamping legs, together with the contact section of the busbar, form a clamping portion for clamping the electrical conductor between the clamping legs and the contact section. In the open position, at least the clamping edges of the clamping legs pivot away from the contact section of the busbar. The clamping legs can, for example, pivot between an open position and a clamped position, in which the electrical conductor can move freely between the clamping legs and the contact section, and in which the clamping position the clamping legs clamp the electrical conductor at the contact section.

[0016] The retaining element can act directly on the clamping leg, for example, to hold the clamping leg in the open position. Therefore, for example, a first locking element can be provided at the clamping leg and a second locking element at the retaining element, wherein the first and second locking elements can lock into each other in the open position. The first locking element can be configured as a locking protrusion or a locking hook. The second locking element can be configured as a locking edge or a locking opening.

[0017] The retaining element can exist as a separate component, for example, fastened to the insulating housing of the terminal block, fastened to the busbar, or fastened to other components. The retaining element can also be integrally formed with the clamping spring.

[0018] According to an advantageous design of the invention, the retaining element is positioned behind the clamping portion or substantially behind the busbar in the wire introduction direction from the conductor to the spring-forced clamping connector. In this manner, the retaining element does not obstruct the insertion of the conductor. For example, the retaining element can be in the open position, that is, when the clamping legs are locked at the retaining element, so that, when viewed in the wire introduction direction, it does not extend into the wire receiving space or only slightly extends into the wire receiving space relative to the clamping legs.

[0019] According to an advantageous design of the invention, the spring-force clamping connector has a release element, by which actuation of the release element can deflect the retaining element until the clamping leg held at the retaining element is released from the retaining element: the release element may have a release section. When the wire to be clamped applies an actuating force to the release section, the clamping leg held at the retaining element in the open position can be released from the retaining element by the release element. This allows the clamping leg to be automatically released from the retaining element by inserting the wire. The release section can be achieved by applying pressure through a separate tool, a terminal component, such as an actuating element, or directly via the introduced wire itself. By means of the release element, the clamping leg held at the retaining element in the open position can be released from the retaining element by applying pressure to the release section in the wire introduction direction L of the wire to be connected. Depending on the configuration of the spring-force clamping connector, the release element may be configured as part of the clamping spring, for example, as a release element integrally formed with the clamping spring, or as a separate component.

[0020] According to an advantageous design of the invention, the releasing element is a component or assembly of the spring-force clamping connector, the component or assembly having a retaining element. This keeps the structural and assembly costs for the spring-force clamping connector low. Therefore, in particular, it is not necessary to assemble two different components or assemblies for assembling the releasing element and the retaining element, but only one component or assembly is assembled. For example, the releasing element can be molded in one piece with the retaining element. The component or assembly can be made of, for example, plastic or metal or a combination of these materials.

[0021] According to an advantageous design of the invention, the clamping spring has a support section configured to support the clamping spring at the busbar. This support section allows for reliable support of the clamping spring and sufficient support relative to the spring force applied by the clamping legs.

[0022] According to an advantageous design of the invention, the support section has a base section and a fastening section, wherein clamping legs branch off from the base section, and the support section engages the busbar from the rear with its fastening section, such that the busbar is supported at the fastening section and at least partially disposed between the base section and the fastening section. Here, the clamping legs can branch off from the base section, particularly without a 180° spring bow. For example, the clamping legs can branch off from the base section at an acute angle, which, for example, can be less than 60° in the open position. The base section can be connected to the fastening section via a connecting section. For example, the base section can extend substantially parallel to the fastening section, or can have a small angle relative to the fastening section, particularly less than 20°.

[0023] According to an advantageous design of the invention, a wire guide channel for guiding the electrical wire to be fixedly clamped at the contact section can be formed in the insulating material housing, wherein the release section of the release element is disposed in the wire guide channel or at least extends into the wire guide channel or is at least disposed in the extension of the wire introduction channel.

[0024] According to an advantageous design of the invention, the releasing section of the releasing element may be disposed behind the contact section or at least behind the clamping section along the direction of wire introduction.

[0025] In the context of this invention, the indefinite term "a" is not to be understood as a numeral. Therefore, if, for example, a component is referred to, this should be interpreted in the sense of "at least one component." Angles are described in degrees, referring to the dimension of a circle of 360 degrees (360°). Attached Figure Description

[0042] Figure 15 Another embodiment of the combined retain-release element is shown in a perspective view. Detailed Implementation

[0043] Figure 1 and Figure 2 A terminal 1 with an insulating housing 2 is shown. The insulating housing 2 has a wire introduction opening 20 on the wire introduction side, through which an electrical wire can be introduced into the insulating housing 1 in the wire introduction direction L and clamped at a spring-force clamping connector.

[0044] It can be seen that a spring-force clamping connector is provided in the insulating material housing 2, the spring-force clamping connector having a clamping spring 4 and a busbar 3. The clamping spring 4 has a support section 41, through which the clamping spring 4 is supported at the busbar 3. In addition, the clamping spring 4 has a clamping leg 43 branching off from the support section 41 at an acute angle. The clamping leg 43 extends toward a free end, at which the clamping leg 43 has a clamping device for fixing the clamping wire. Figure 2 The clamping edge 46 can be seen in the image. Figure 1 In the clamping position shown, when no electrical wire is introduced, the clamping leg 43 and the clamping edge 46 are pressed against the contact section 31 of the busbar 3. The electrical wire can be fixedly clamped at the clamping part 30 between the clamping leg 43, or the clamping edge 46, and the contact section 31.

[0045] The support section 41 extends from the base section 40 to the connecting section 42, which is angled relative to the base section, and the clamping leg 43 branches off from the base section. The connecting section 42 transitions into the fastening section 44, which is angled relative to the connecting section 42. The fastening section 44 engages the manifold 3 from the rear, that is, the fastening section rests against the side away from the clamping part 30, that is, against the back side of the manifold 3.

[0046] Furthermore, terminal 1 has a retaining element 5 by which the clamping leg 43 can be held in the open position. The retaining element 5 has a locking element 50, which can engage with a locking element configured as a mating member at the clamping leg 43 in the open position. The clamping leg 43 can then not be easily moved back to the clamped position. The locking element configured at the clamping leg 43 can, for example, be formed by a clamping edge 46 as shown in the figures. However, at least one separate locking element can also be configured at the clamping leg 43, for example, in the form of a protruding locking tab, which can then engage with the locking element 50.

[0047] For manipulating the clamping legs 43, or for manipulating multiple such clamping legs 43, such as adjacent second clamping legs 43, the terminal 1 has an actuating element 6, which actuates in... Figures 1 to 6The embodiment shown is configured as a pivotable joystick. The control element 6 has a manual operating section 60, where the control element 6 can be manually operated by the user, that is, pivotal movement of the control element 6 can be performed. For this purpose, the control element 6 is supported in an insulating housing 2 at a support portion 61. The control element 6 can pivot about the support portion 61, such as... Figure 1 and Figure 3 The comparison is shown.

[0048] The operating element 6 extends into the insulating housing 2 via the operating section 62 up to the clamping leg 43. Figure 1 This is shown the clamping leg 43 before it is deflected by the actuating element 6. The clamping leg is in the clamped position, in which the free end of the clamping leg can, for example, rest against the contact section 31 of the busbar 3. Figure 3 In this position, the manual operating element 6 has been pivoted. As a result, the clamping leg 43 is deflected away from the contact section 31 by the operating section 62 until the clamping leg is locked at the locking element 50 of the retaining element 5 by its clamping edge 46 or other locking element, thereby holding it in the open position.

[0049] Figure 4 The terminal 1 is shown in a perspective view of the wire introduction side of the insulating material housing 2, where two wire introduction openings 20 are present. Therefore, in this case, the terminal 1 is configured as a bipolar terminal, but it can also be designed similarly as a multipolar terminal with more than two spring-forced clamping connectors. It can be seen that the operating element 6 is located between the wire introduction openings 20, particularly at locations where, in known terminals, a partition wall of the insulating material housing 2 is formed between the wire introduction openings 20. This partition wall can be omitted in the illustrated embodiment because it can be at least largely replaced by the operating element 6, particularly a manual operating section 60, and / or a portion of the insulating material housing connected to the manual operating section 60.

[0050] Figure 5 An advantageous design of the control element 6, configured as a pivotable joystick, is shown. Because the control element 6 is configured to operate two adjacent clamping legs, the control section 62 can extend in the width direction beyond the other relatively narrow configurations of the control element 6, allowing the control element 6 to be designed in a hammer shape.

[0051] according to Figure 6This demonstrates how the releasing element 8 can be integrated into the terminal block 1. The releasing element 8 is used to release the clamping leg 43 from the retaining element 5. The releasing element 8 has a releasing section 80 that can be manipulated by an inserted electrical wire. If pressure is applied to the releasing section 80 by the electrical wire, the retaining element 5, together with the locking element 50, shifts slightly toward the rear housing wall 21 of the insulating housing 2 until the clamping leg 43 can be released from the locking element 50. The clamping leg 43 then springs back until it rests against the inserted electrical wire and presses the wire against the contact section 31.

[0052] When the releasing section 80 is operated, the releasing element 8 can mechanically act on the retaining element 5 via the transmission section 81. As a result, the retaining element 5, which is rotatably suspended at the rotating support 55, can rotate slightly, thereby releasing the latch between the locking element 50 and the clamping edge 46. The rotating support 55 can, for example, be configured as a pin 47 protruding from the connecting section 42, as described above. Figure 11 As can be seen, the pin engages with the opening 56 at the retaining element 5. The releasing element 8 can be configured, for example, as a rocker, which can pivot when operated at the releasing section 80.

[0053] Figures 7 to 11 An embodiment of a terminal block 1 with an operating element 6 disposed between two adjacent wire inlet openings 20 is shown, the operating element being configured as a movable press member. The operating element 6 also has a manual operating section 60, which can be operated by a user pressing it from the wire inlet side. Due to this pressing operation, the operating element 6 further moves into the insulating material housing 2, such as... Figure 8 As indicated. Through the aforementioned movement, the actuating element 6, by means of its actuating section 62, causes the clamping leg 43 to move from the... Figure 7 The clamping position shown in the figure moves to the position where Figure 8 In the open position shown, the clamping leg 43 is spaced apart from the contact section 31 by its clamping edge 46. In the open position, the clamping leg 43 can be locked again at the locking element 50 by means of its clamping edge 46.

[0054] Figure 9 With Figure 4 Terminal 1 is shown in a similar manner, however, this terminal has an operating element 6 configured as a movable pressing member.

[0055] like Figure 10 As shown, the control element 6 is also located in the area of ​​the control section 62 as per [the description of the control element 6]. Figures 1 to 6 The actuating element is shaped like a hammer so that two adjacent clamping legs can be deflected.

[0056] Figure 11 and Figure 6 Similarly, a terminal 1 with a release element 8 is shown, the release element being used in accordance with... Figure 6 The similar methods described constitute and function.

[0057] Figure 12 A clamping spring 4 is shown as an example, wherein two clamping legs 43 are implemented in a one-piece structural unit. Therefore, the clamping spring 4 is suitable for clamping the connector with two spring forces arranged side-by-side. The clamping spring 4 can be used in all the aforementioned terminals. The different sections of the support section 41 can be seen, namely the base section 40, the connecting section 42, and the fastening section 44. Additionally, a pin 47, for example in the form of a pin, molded at the connecting section 42, can be seen for receiving and supporting the retaining element 5, as will be described later.

[0058] Figure 13 Busbar 3 is shown, which provides two side-by-side receiving positions for electrical conductors at its contact section 31, and is correspondingly adapted to... Figure 12 The clamping spring 4 shown is used to achieve two side-by-side spring force clamping of the connector. A retaining device 34 for holding the retaining element 5 can be molded at the busbar 3.

[0059] Figure 14 The combined retaining-releasing elements 5 and 8 are shown, which can be used as an alternative to the aforementioned terminal block 1. Unlike embodiments where retaining element 5 and releasing element 8 are separate components, retaining element 5 and releasing element 8 are here formed as a one-piece structural unit, for example, made of a plate in the form of a stamped and bent piece.

[0060] The retaining-releasing elements 5 and 8 each have a retaining element 5 having two spaced-apart sidewalls 57 extending parallel to each other. Each sidewall 57 has an opening 56 into which a corresponding pin 47 of the connecting segment 42 can be inserted to form a swivel support 55. A locking element 50 is formed at the free end of each sidewall 57. On the other side, the sidewall 57 is connected to the releasing element 8 via a lower longitudinal segment 53.

[0061] When force is applied to the release section 80 via the electrical conductor 9, the entire holding-releasing elements 5 and 8 pivot about the rotating support 55. As a result, the locking element 50 is slightly displaced rearward in the direction of the conductor introduction L, allowing the clamping leg 43 to be released from the locking element.

[0062] Figure 15Another embodiment of the combined retain-release elements 5, 8 is shown, which can also be used as an alternative in the aforementioned terminal block 1. The retain-release elements 5, 8 have a retaining element 5, which has a locking element 50, as mentioned above, at its free end.

[0063] The retaining element 5 has a form-fitting connecting element 51 in the area where the locking element 50 is located. This connecting element can be inserted into the receiving element 47 of the support section 41. Thus, the locking element 50 can be supported on the support section 41, particularly on the connecting section 42, relative to the spring force applied by the clamping leg 43 in the open position. The retaining element 5 transitions to the releasing element 8 via an upper longitudinal section 52, where a releasing section 80 is provided. The releasing section 80 is connected on its opposite side via a lower longitudinal section 53 to a fastening section 54 of the retaining-releasing elements 5, 8. This fastening section can be hooked into a retaining device in the retaining device 34 at the busbar 3. Thus, the entire retaining-releasing element 5, 8 is secured at the busbar 3.

[0064] Therefore, when force is applied to the release section 80 via the electrical wire 9, the lower regions of the retaining-release elements 5 and 8 are fixed and do not shift, and these lower regions are fastened to the retaining device 34 via the fastening section 54. Correspondingly, only the upper regions of the retaining-release elements 5 and 8 with the locking element 50 shift due to the inserted electrical wire 9 and the release section 80.

[0065] In addition, Figure 15 As can be seen, the combined retaining-releasing elements 5, 8 may not be configured as continuous plates in the region of the upper longitudinal section 52, but may instead have a first gap 58 between the upper longitudinal sections 52. Similarly, the combined retaining-releasing elements 5, 8 may not be configured as continuous plates in the region of the lower longitudinal section 53, but may instead have a second gap 59 between the lower longitudinal sections 53. The first and / or second gaps 58, 59 can improve the elasticity of the retaining-releasing elements 5, 8, thereby reducing the required releasing force, which must be applied to the releasing section 80 via the inserted electrical wire 9. Another advantage of the first and / or second gaps 58, 59 is that they provide an observation window through which, at least when a transparent housing material is used in the region, it can be visually inspected whether the electrical wire 9 has been extended sufficiently into the insulating housing 2.
