Description

Technical Field

[0001] This invention relates to a terminal block having a housing and a plurality of spring-force clamping connectors, each of which has at least one clamping spring for clamping an electrical conductor by means of spring force. The terminal block has an individualized actuating element associated with each of the spring-force clamping connectors, which can be individually manually operated. Manual operation of the individualized actuating element can individually, i.e., independently of the other clamping springs, operate the clamping spring of the associated spring-force clamping connector to an open position. Furthermore, this invention relates to an electrical plug connector, particularly a circular plug connector, having at least one such terminal block. Background Technology

[0002] Such terminal blocks are known from EP 2 956 992 B1. Summary of the Invention

[0003] The purpose of this invention is to provide a further improved terminal block.

[0004] The objective is achieved in the type of terminal block mentioned at the beginning by having at least one manually operable rotary actuating element, rotatably supported in the housing, and by means of rotational movement, manually operating the rotary actuating element to jointly operate the clamping springs of multiple or all spring-force clamping connectors into the open position. This invention enables the user of such a terminal block to, as needed and as circumstances, either operate the individual clamping springs or only one clamping spring into the open position by operating the respective individual actuating element, or alternatively, operate the rotary actuating element (which thus forms a general actuating element for multiple or all clamping springs) to jointly operate the clamping springs of all spring-force clamping connectors operable via the general actuating element to the open position. For example, it is helpful to jointly operate multiple or all spring-force clamping connectors via the general actuating element when the terminal block is to be initially wired. Conversely, if partial rewiring is to be performed at an already wired terminal block, it is generally undesirable to operate all clamping springs into the open position; instead, only the clamping springs to be rewiring should be operated. Therefore, individual control elements can be operated by the user. For example, the clamping spring can be directly manipulated to the open position through the main control element, meaning that the main control element can act directly on the clamping spring.

[0005] In an advantageous design, the individual operating element can be directly operated manually by the user without additional tools. It is also conceivable that the individual operating element is designed to be operated additionally with the aid of tools, or only with the aid of tools. Specifically, the individual operating element can be operated at a corresponding manual operating section on the outside of the terminal housing or within the operating channel of the housing. The main operating element can advantageously be directly operated manually by the user without additional tools. The terminal housing can be constructed as an insulating material housing.

[0006] Furthermore, it is advantageously possible in the terminal block according to the invention to operate multiple or all clamping springs together to the open position by means of a main operating element, and then, after the wire is connected to the spring force clamping connector, to move the respective individual clamping spring to the clamping position by operating the respective individual operating element, in which the wire is clamped at the spring force clamping connector.

[0007] By configuring the main control element as a rotary control element, the user can operate the terminal block in a comfortable and ergonomic manner. A relatively large force can be applied by rotating the control element, so that a larger number of clamping springs can be tensioned simultaneously when the control element is rotated, for example, by moving the clamping legs of the clamping springs to the open position.

[0008] The spring-loaded clamping connector may have a busbar with a contact section for clamping an electrical wire. The clamping spring may have clamping legs for clamping the electrical wire. The clamping legs can be deflected into an open position by individualized actuating elements and rotational actuating elements. The clamping legs, together with the contact section of the busbar, form a clamping portion for clamping the electrical wire between the clamping legs and the contact section. The open clamping portion (open position) is characterized in that at least one clamping edge of the clamping leg pivots away from the contact section of the busbar, that is, has a larger distance from the contact section compared to the clamping position. The clamping legs may, for example, pivot between the open position and the clamping position, in which the electrical wire can move freely between the clamping legs and the contact section, and in which the clamping position the clamping legs clamp the electrical wire at the contact section.

[0009] According to an advantageous design of the invention, a rotary actuating element is configured to indirectly actuate the corresponding clamping spring to the open position by manipulating a personalized actuating element associated with the clamping spring. In this way, the terminal block can achieve indirect opening of the clamping portion by rotary actuation.

[0010] According to an advantageous design of the invention, the rotary control element has a body from which a plurality of control arms extend axially, wherein each control arm is configured to transmit control force from the rotary control element to individual control elements or clamping legs for deflecting the corresponding clamping legs into an open position. In this way, control force can be selectively transmitted from the rotary control element to individual control elements or clamping legs. Consequently, the individual control elements can be located in ergonomically advantageous positions at the terminals, making them readily accessible for individual (individualized) manual operation.

[0011] Each individual control element may, for example, have a gripping section at which it can be manually operated. The gripping sections may be accessible on the outside of the housing and, correspondingly, manually operable. Manual operation can be performed either directly with the fingers, i.e., without tools, or with the use of tools. The gripping sections of the individual control elements may, for example, all be located on the same housing side of the terminal block, such as on the housing side where a wire inlet for spring-clamping the connector is also present. The gripping sections may also be located on different housing sides of the terminal block. If the terminal block has a circular housing, the gripping sections may, for example, be located on the circumferential side of the circular housing shape.

[0012] According to an advantageous design of the invention, at least one control profile extending in the direction of rotation of the rotary control element is formed at the corresponding control arm, through which the individual control element or clamping leg can be loaded with control force by the rotary control element. This inclined control profile (or, in other words, a control ramp, for example) allows for efficient transmission of control force from the rotary control element to the individual control element or clamping leg.

[0013] At the corresponding individualized control element, for example at its gripping section, there may be a force-absorbing profile of a mating part shaped as an inclined extension relative to the control arm, the force-absorbing profile being inclined, for example, also to the rotation direction of the rotary control element, for example, parallel to the extension of the control profile of the control arm.

[0014] According to an advantageous design according to the invention, a corresponding actuation profile configuration is provided for applying actuation forces to respective individualized actuation elements or clamping legs, said actuation forces having at least one force component acting in the axial direction and / or at least one force component acting in the radial direction. Here, the axial and radial directions relate to the rotation axis of the rotary actuation element about which the rotary actuation element can rotate.

[0015] This axial force component can be used to move a customized control element, for example, in the axial direction or along the longitudinal direction of the circular housing of the terminal block, by the torsion of the rotational control element. This method of operation is well suited, for example, to customized control elements configured as actuating presses or actuating sliders and movably supported in the direction of movement.

[0016] The force component acting in the radial direction is well-suited for manipulating individualized control elements configured as pivotable levers. The force component acting in the radial direction can, for example, act in a radially outward pointing direction. Thus, this force component can be used to pivot the individualized control element or its gripping portion radially outward relative to the outer contour of the housing.

[0017] According to an advantageous design of the invention, one, several, or all individualized operating elements are configured as pivotable levers, movable operating buttons, or other sliding operating elements. In this way, the terminal blocks can be optimally matched to the respective intended use in terms of individualized operating elements, depending on whether lever operation, button operation, or slider operation is more advantageous. Here, the movable operating button is characterized in that it is movably disposed in the operating channel of the housing and can be operated by applying a pressing force to an end face accessible on the outside of the housing. In contrast, although a sliding operating element can also perform a moving motion like a operating button, it can be operated by means of a manually operated section supported on the outside of the housing and movable along the outside.

[0018] According to an advantageous design of the invention, a spring-loaded clamping connector is arranged in an annular shape within the housing of the terminal block. The annular spring-loaded clamping connector circumferentially surrounds the center of the terminal block housing.

[0019] According to an advantageous design of the invention, the rotary actuating element has an annular body that circumferentially surrounds the region bounded by the annular shape of the connector clamped by spring force. Therefore, the annular body can be configured as an actuating ring. The annular body can, for example, be rotatably supported on the outside of the housing of the terminal block.

[0020] According to an advantageous design of the invention, the rotary actuating element is configured for manual operation at its annular body, on the circumferential side of the annular housing of the terminals. This allows for a good grip on the annular body by hand and ensures good force transmission.

[0021] According to an advantageous design of the invention, the individualized operating element is configured to be operated outside the area bounded by the annular shape of the connector clamped by spring force. This has the advantage that the user can comfortably operate the gripping section of the individualized operating element from the circumferential side of the circular housing of the terminal block. The gripping section of each individualized operating element can be positioned, at least primarily, outside the area bounded by the annular shape of the connector clamped by spring force. Alternatively, each individualized operating element can be positioned, at least primarily, outside the area bounded by the annular shape of the connector clamped by spring force.

[0022] Alternatively, individualized control elements can be configured to be manipulated within a region bounded by a ring-shaped body clearance. Each individualized control element can be positioned, at least primarily, within the region bounded by the ring-shaped body clearance.

[0023] According to an advantageous embodiment of the invention, the rotary actuating element is configured as an actuating element rotatable about the longitudinal axis of the annular shape of the spring-forced clamping connector. Correspondingly, the axis of rotation of the rotary actuating element is orthogonal to the planar extension defined by the annular shape of the spring-forced clamping connector.

[0024] According to an advantageous design of the invention, one, several, or all individualized operating elements can be fixed at at least one member of the terminal block or in a dead-end position when reaching the open position, wherein the clamping legs are held in the open position by means of the individualized operating elements in the fixed position. This has the advantage that the clamping legs can be held in the open position for a longer period of time without further manual operation of the respective individualized operating elements or rotary operating elements. More specifically, the user can, for example, place all clamping legs in the open position via the individualized operating elements by rotating the operating elements, and the open position is then maintained by the fixing function of the individualized operating elements as described.

[0025] According to an advantageous design of the invention, the individual operating element has a first locking element, which, in the open position, can lock the individual operating element to a second locking element of another component of the terminal block, particularly the busbar or insulating housing, by means of the first locking element. This allows for particularly reliable securing of the individual operating element in the open position of the clamping legs. The individual operating element will not be accidentally released by the locking mechanism, even under vibration loads, for example, at the terminal block. Of course, the user can release the locking mechanism of the individual operating element again at any time by manual operation.

[0026] According to an advantageous design of the invention, the terminal block has a release element with a release section for one, more, or all spring-forced clamping connectors. When the release section is applied with a release force via an inserted wire, the corresponding individualized operating element in the open position can be released by the release element, and the clamping leg can automatically move from the open position toward the clamping position. Thus, the terminal block can be easily extended to provide automatic wiring functionality for spring-forced clamping connectors.

[0027] Furthermore, the aforementioned objective is achieved through an electrical plug connector, particularly a circular plug connector, having at least one terminal block of the type previously described. This also allows the previously described advantages to be realized.

[0028] In the context of this invention, the indefinite term "a" should not be understood as a numeral. Therefore, if, for example, a component is referred to, it should be interpreted in the sense of "at least one component." As long as the angle is described in degrees, the angle description refers to a circle of 360 degrees (360º). Attached Figure Description

[0044] Figure 1 An embodiment of a terminal block 1 is shown, the terminal block having an insulating housing 2. A plurality of spring-loaded clamping connectors are housed within the housing 2. In the illustrated embodiment, the spring-loaded clamping connectors are arranged around a center in the housing 2 along a circular trajectory, for example, on a circular trajectory. However, the invention also relates to terminal blocks having a different housing structure type and a different arrangement of spring-loaded clamping connectors, for example, spring-loaded clamping connectors arranged side-by-side in a row.

[0045] Figure 1 The terminal 1 is shown from a viewpoint toward the wire entry side, in which the housing 2 has a wire entry opening 20 for each spring-forced clamping connector. Electrical wires can be introduced into the housing 2 through the wire entry opening 20 and clamped at the spring-forced clamping connector.

[0046] Additionally, terminal 1 has a rotary actuating element 6 for actuating the spring-force clamping connectors. This rotary actuating element, for example, is configured to move the clamping legs of the clamping springs of all spring-force clamping connectors to an open position when manually actuated. The rotary actuating element 6 may have an annular body 60, which is rotatably supported on the circumferential side of the housing 2 and can be twisted relative to the housing 2 about the rotation axis A in the direction of rotation D. Here, the actuating force for twisting the rotary actuating element 6 can be applied directly to the body 60, particularly the outer circumferential side of the body. For this purpose, the body 60 may have grooves or other contours on its circumferential side, by which the additional contours increase grip. Terminal 1 has an individualized actuating element for each spring-force clamping connector. Figure 1 Only the gripping section 52 of the individualized control element is visible on the outer side of the housing 2. This gripping section is used to apply manual operating force. The individualized control element can be configured as a movable control element in the form of a control press or a control slider.

[0047] In addition, each spring-force clamping connector has, for example, in Figure 2 The busbar 3 shown is an example of... Figure 3 The clamping spring 4 is shown. The busbar 3 has a contact section 30 where electrical wires can be clamped. Furthermore, the busbar 3 has a spring retaining section 31 opposite to the contact section 30, for example, disposed substantially parallel to the contact section, where a retaining element 34 may be provided for retaining the clamping spring 4. The contact section 30 may be connected to the spring retaining section 31 via one or two connecting walls 32, 33. The connecting walls 32, 33 may be designed, for example, as sidewalls of a region of the busbar 3 that is integrally framed. The busbar 3 forms a contact frame in this way into which the clamping spring 4 can be inserted.

[0048] Terminal 1 can be configured as an electrical plug connector, for example. Thus, bus 3 can be connected to the plug connector 10 of the plug connector or be integrally formed with the plug connector.

[0049] The clamping spring 4 has a support leg 41, a spring bow 42 connected to the support leg 41, and a clamping leg 43 connected to the spring bow 42. The clamping leg 43 has a clamping edge 46 at its end opposite to the spring bow 42, the clamping edge being used to clamp the electrical wire at the contact section 30. An operating section 44 branches from at least one side of the clamping leg 43, for example in the form of an operating tab. The operating section 44 is used to operate the clamping leg 43 by means of an operating element 6, as further described in detail. A fastening element 40 is formed at the support leg 41, the fastening element having, for example, an opening extending through the support leg 41, by means of which the support leg 41 can be fastened to the retaining element 34, such as... Figure 4 As indicated.

[0050] Figure 4 A spring-force clamping connector 9 is shown, the spring-force clamping connector having a spring force ... Figure 2 Busbar 3 and according to Figure 3 The device consists of a clamping spring 4. Here, the clamping spring 4 is hooked into the contact frame of the busbar 3. The clamping spring 4 is now supported on the spring holding section 31 by means of its support leg 41, and the clamping spring 4 is supported relative to the force of the clamping leg 43 in this way. It can be seen that the operating section 44 extends laterally from the connecting wall 33. For this purpose, a corresponding opening can be formed in the connecting wall 33. Additionally, there is an individualized operating element 5.

[0051] The individualized control element 5 has a body 50, on which a laterally extending guide pin 55 is provided on one longitudinal side or on two opposing longitudinal sides. Furthermore, the body 50 has at least one spring-loaded section 51, which, for example, has an operating surface extending obliquely relative to the movement direction V of the individualized control element 5. An operating section 44 clamping the spring 4 deflects by means of the operating surface during the movement of the individualized control element 5. A first locking element 53 is provided on the body 50. Additionally, the individualized control element 5 has a gripping section 52, which can be integrally formed with the body 50 and extends from the body as a longitudinal section opposite to the movement direction V. The gripping section 52 is configured to apply a manual operating force.

[0052] Figure 5 Showing according to Figure 1 A partial cross-sectional view of terminal 1, showing the area where the spring force clamps the connector 9. It can be seen that the individualized operating element 5 can be operated at the gripping section 52 on the outside of the housing 2. The gripping section 52 can, for example, be movably supported in the operating channel 21 of the housing 2. The main body 50 can be completely inside the housing 2. Figure 5In the initial position, the individualized control element 5 is not yet actuated by the clamping leg 43 or the control section 44 via the spring-loaded section 51. Correspondingly, the clamping leg 43 is in its clamping position.

[0053] The guide pin 55 is guided in the guide groove 25 of the insulating material housing 2. It can be seen that the main part of the guide groove 25 is formed as a straight, extending section parallel to the direction of movement V. The guide groove 25 has a curved section at its rear end toward the open position. Through this curved section 24, the individualized operating element 5 is additionally guided in pivoting motion via the guide pin 55; that is, the curved section 24 causes the pivoting motion of the individualized operating element 5.

[0054] exist Figure 6 The diagram shows the individualized control element 5 in a fully manipulated state. The individualized control element 5 is now moving away from its initial position along the direction of movement V. The clamping leg 43 deflects toward the open position via the spring-loaded section 51. If a specific position is reached during this movement, such as in... Figure 6 As shown, the actuating element 6, which linearly shifts in the direction of movement V until it reaches the specific position, can additionally perform a pivoting or tilting motion. Through this pivoting or tilting motion, the first locking element 53 engages with the second locking element 22, which may be located, for example, in the housing 2. Thus, the individualized actuating element 5 is locked in the open position and, correspondingly, will not move back to the initial position due to the clamping leg 43. Here, the pivoting motion of the individualized actuating element 5 can be caused or at least supported by the spring force of the clamping spring 4 acting on the individualized actuating element 5 from the clamping leg 43. Therefore, the force of the clamping spring 4 ensures a reliable lock between the first locking element 53 and the second locking element 22.

[0055] The release of the latch is preferably achieved by an inserted electrical wire that contacts the release element 8 at terminal 1. Here, the release element 8 can be located at the individual operating element 5, the busbar 3, or the housing 2, such that the inserted electrical wire applies force to the individual operating element 5 via the release element 8, causing the individual operating element 5 to perform a movement that releases the latch.

[0056] The release element 8 can be configured, for example, to deflect a wire inserted in a wire introduction direction parallel to the direction of movement V, such that the free end of the wire is deflected by the release element 8, for example by means of an inclined portion formed at the release element 8, to the tiltable individualized actuation element 5. By inserting the wire (with its end deflected and contacting the individualized actuation element 5), the individualized actuation element 5 can be released from its position, i.e., tilted back again to the position... Figure 5The wire is positioned as shown in the diagram and is pushed back to its initial position by the spring force of the clamping leg 43. Here, the wire is clamped by the clamping leg 43.

[0057] Figure 7 One embodiment of the terminal block 1 is shown, which in turn has a circular housing. A rotary actuating element 6 is also present, having an annular body 60. A plurality of actuating arms 61 extend axially from the annular body 60. The actuating arms 61 are respectively used to transmit actuating force from the rotary actuating element 6 to individual actuating elements 5. In this case, the individual actuating elements 5 are configured as sliding actuating elements, each having a gripping section 52 for applying manual actuating force. The gripping sections 52 are accessible for manual operation on the circumferential side of the terminal block 1.

[0058] An operating profile 62 is formed at each operating arm 61, serving as a mechanical interface for transmitting operating force from the rotary operating element 6 to the corresponding individual operating element 5. This operating profile is oriented at an angle to the rotational direction D of the rotary operating element 6. For this inclined operating profile 62, a force-absorbing profile 54, also oriented to the rotational direction D, is provided at the individual operating element 5, particularly at the gripping section 52. When the rotary operating element 6 rotates, the operating profile 62 contacts and slides along the force-absorbing profile 54. Consequently, the corresponding individual operating element 5 moves in the axial direction, i.e., parallel to the rotation axis A, thereby opening the corresponding clamping portion; that is, the clamping leg 43 of the clamping spring 4 moves from the clamping position to the open position.

[0059] Figure 8 Showing according to Figure 7 In a variant of the terminal block, the individualized operating element 5 is entirely housed within the housing 2, and correspondingly, it does not have a gripping section 52 accessible from the outside of the housing 2. Thus, the operation of the individualized operating element 5 is performed within the housing 2, for example, as described above.

[0060] Figure 9 Indicates that according to Figure 7 The construction of the corresponding individualized operating element 5 in one embodiment of the terminal block is shown in particular. The force-absorbing profile 54, extending at an angled extension at the gripping section 52, is particularly noticeable. The individualized operating element 5 also has a spring-loaded section 51, for example, similar to that according to... Figure 4 As explained.

[0061] Figure 10 Showing according to Figure 1 and Figure 7The terminal block is a single component of the rotary actuating element 6. Multiple actuating arms 61 can be seen, which extend from the annular body 60 and have an inclined actuating profile 62.

[0062] Figure 11 A rotary control element 6 is shown, which also has an annular body 60 and a control arm 61 extending from the body 60. Control profiles 62, extending obliquely in the rotation direction D, are formed on the control arm 61. Figure 10 In this implementation, the actuation profile 62 is oriented such that it is configured, at least primarily, to transmit the force component acting in the axial direction to the corresponding individualized actuation element 5. Figure 11 The following embodiment is shown in which the manipulation profile 62 is oriented such that the manipulation profile is configured at least primarily for transmitting force components acting in the radial direction, particularly force components acting radially outward.

[0063] In this embodiment, the manipulation profile 62 can advantageously be implemented in two parts and includes a first partial profile 63 and a second partial profile 64. At the start of the opening movement, the helical first partial profile 63 is active. During further movement of the opening movement, the helical / spiral-shaped second partial profile 64, formed in the axial direction, additionally becomes active. At the end of the opening movement, (almost) only the second partial profile 64, which is formed at the axial end of the manipulation arm 61, is active.

[0064] according to Figure 11 The rotary manipulation element can advantageously be used in, for example, in Figure 12 The terminal block 1 is used in the example shown. The terminal block 1, within the housing 2, has multiple spring-loaded clamping connectors 9 and corresponding individualized operating elements 5 associated with each spring-loaded clamping connector 9. In this case, the individualized operating element 5 is configured as a pivotable lever. Each individualized operating element 5 has a gripping section 52, at which the user can manually operate each individualized operating element 5, particularly on the outer circumference of the housing 2. Each individualized operating element 5 has an eccentrically formed spring-loaded section 51, through which the corresponding clamping leg 43 deflects when the individualized operating element 5 pivots, such that the operating force is transmitted from the eccentrically formed spring-loaded section 51 to the operating section 44 of the clamping leg 43.

[0065] like Figure 13 As indicated, the individualized control element 5 is configured such that, during manual operation, the corresponding gripping section 52 pivots outward, i.e., pivots outward from the housing 2. Figure 13In the middle, the rotating control element 6 has rotated slightly in the rotation direction D, but has not yet rotated completely. It can be seen that the clamping leg 43 has moved slightly toward the open position.

[0066] Figure 14 The following is shown in the case of fully manipulating the rotary control element 6. Figure 12 Terminal 1. Now, all individual operating elements 5 are also fully operated by the rotary operating element 6 and are in the over-dead position. In this position, the position of the individual operating elements 5 is maintained even when the rotary operating element 6 is rotated back to the initial position. The force exerted on the individual operating elements 5 by the clamping leg 43 does not cause the individual operating elements 5 to reset in the over-dead position. In order to move the clamping leg 43 into the clamping position, the user must then manually operate the individual operating elements 5 at the gripping section 52 to move the individual operating elements back at least slightly toward the initial position. Then, further back to the initial position can be achieved by the reset force exerted by the clamping leg 43.
