Description

[0001] conductor connection terminal

[0002] The invention relates to a conductor terminal with an insulating housing which has at least one conductor entry opening for receiving an electrical conductor in a conductor entry direction, wherein a contact insert is arranged in the insulating housing which has at least one spring-loaded clamping connection with a busbar and a clamping spring, wherein the clamping spring has at least one clamping leg for clamping the electrical conductor by means of spring force to a contact section of the busbar and a support leg connected to the clamping leg by which the clamping spring is supported against the spring force of the clamping leg, wherein at least one first support element is arranged on the busbar on which the clamping spring can be supported with its support leg.

[0003] The conductor connection terminal can, for example, be designed in the form of a distribution terminal block, which has an insulating housing with several conductor entry openings and spring-loaded clamping terminals arranged in the housing and accessible via the conductor entry openings for connecting electrical conductors, wherein the spring-loaded clamping terminals are electrically connected to each other via a busbar. Such a conductor connection terminal is known from EP 2 456 011 B1.

[0004] The invention is based on the objective of further improving such a conductor connection terminal.

[0005] This problem is solved in a conductor terminal of the type mentioned above by arranging at least one second support element on the insulating housing, against which the clamping spring can rest with its contact leg. Thus, in the conductor terminal according to the invention, one and the same clamping spring, or rather its contact leg, can be supported at two different points: on the first support element on the busbar and, alternatively or additionally, on the second support element on the insulating housing. The insulating housing is typically made of an insulating material, usually plastic. Due to the support provided by the inventive clamping spring, the clamping spring can be mounted directly into the insulating housing. Potential problems associated with simply supporting the clamping spring on the insulating material, e.g.,Fatigue issues arising from the plastic can be avoided by the additional force absorption at the first support element of the busbar, i.e., a metallic support element. The invention also simplifies the assembly and tooling requirements for the components of the conductor terminal block, because a secure spring positioning on the busbar is ensured by an additional seat within the insulating housing. In particular, the clamping spring can be mounted directly into the insulating housing.

[0006] Depending on its age, a terminal block can be in either its manufacturing state or an operating state that follows the manufacturing state. The manufacturing state is defined as the state immediately after the individual components of the terminal block are assembled, i.e., immediately after installation. For example, the manufacturing state might last for a maximum of one hour or one day after installation. The operating state is defined as the permanent state of the terminal block that follows the manufacturing state, for example, when the terminal block has been installed by the user in an electrical installation.

[0007] According to an advantageous embodiment of the invention, the clamping leg of the conductor terminal is supported only on the second support element during manufacturing, and not on the first support element. Thus, during manufacturing, the clamping leg is supported only on the insulating housing, but not on the busbar. This allows the clamping spring and its clamping leg to grip the insulating housing material immediately during assembly, ensuring secure fixation of the clamping spring or contact insert within the insulating housing. This simplifies the manufacturing process of the conductor terminal.

[0008] According to an advantageous embodiment of the invention, the clamping leg of the conductor terminal is supported on the first support element during operation. Thus, in the operating state of the conductor terminal, the clamping spring is supported on the busbar, thereby relieving the second support element on the insulating housing.

[0009] According to an advantageous embodiment of the invention, the support leg is additionally supported by the second support element during operation. Accordingly, the support leg is supported at two points during operation. This automatically results in a load distribution between the forces of the clamping spring absorbed at the first and second support points. The load distribution between the first and second support points can differ; for example, the support force at the first support element can be greater than the support force at the second support element.

[0010] According to an advantageous embodiment of the invention, at least one contact projection is arranged on the support leg, with which the support leg can be supported on the second support element. Such a contact projection allows the support leg to be gripped particularly reliably and efficiently in the plastic material of the insulating housing.

[0011] According to an advantageous embodiment of the invention, the contact insert is secured in the operating state by means of at least one contact projection, or, in the case of multiple contact projections, by means of the contact projections of multiple clamping springs, to the material of the insulating housing. This fixes the contact insert in position within the insulating housing.

[0012] The clamping of the clamping leg or its projection against the insulating housing can occur, for example, in such a way that the clamping leg or projection digs slightly into the material of the insulating housing, caused by the force exerted by the clamping spring. The clamping leg or its projection thus creates a slight indentation in the surface of the insulating housing material.

[0013] According to an advantageous embodiment of the invention, the at least one contact projection has a contact edge pointing towards the associated second support element, in particular a sharp-edged contact edge. This allows for particularly efficient gripping of the contact projection on the material of the insulating housing. The contact edge can be oriented in a direction pointing away from the clamping leg. According to an advantageous embodiment of the invention, the contact leg has a main section from which the at least one contact projection extends at an angle and / or in a curved manner. The main section can, for example, be designed as a flat section or as a slightly curved section from which the contact projection extends at an angle and / or in a more pronounced curve.

[0014] According to an advantageous embodiment of the invention, it is provided that the at least one contact projection extends from the main section in a direction pointing away from the clamping leg.

[0015] According to an advantageous embodiment of the invention, the first support element is formed by a retaining web projecting from the busbar material and extending from a surface of the busbar. In this way, the first support element can be formed integrally with the busbar. This allows for simple manufacturing and assembly of the conductor terminal components.

[0016] According to an advantageous embodiment of the invention, the contact insert has at least two spring-clamp terminals arranged as a pair, with the clamping springs of the pair of spring-clamp terminals arranged back-to-back, in which their contact legs are adjacent to each other and their clamping legs point away from each other. The contact legs are thus arranged between the clamping legs. This allows for particularly efficient placement and assembly of the clamping springs, which is especially advantageous in a conductor terminal block with a plurality of such clamping springs, e.g., in a distribution terminal block.

[0017] According to an advantageous embodiment of the invention, both mounting legs of the pair of spring-clamp connections can be supported on opposite sides of the same first support element and / or opposite sides of the same second support element. Accordingly, only a small number of first and second support elements are required, which further simplifies the design of the conductor terminal.

[0018] The second support element can, for example, be formed in one piece from the material of the insulating housing, such as an inner housing wall or an inner projecting edge of the insulating housing. A distribution terminal block serves to distribute an electrical signal or electrical energy fed into the terminal block via an electrical conductor to several electrical conductors also connected to the terminal block, which generally have a smaller cross-section than the electrical conductor supplying the signal or electrical energy.

[0019] According to an advantageous embodiment, the busbar has at least one retaining web for holding at least one clamping spring, wherein the retaining web has at least one lateral retaining tab which is received for support in retaining grooves of at least one part of the housing. This also provides an advantageous support for a clamping spring. The busbar acts as the support base, i.e., the retaining web is part of the busbar and accordingly designed as a section of a busbar component or connected to such a busbar component. The retaining web can be made of metal, e.g., the same material as the busbar component or a different metal. In particular, the retaining web can have a lateral retaining tab on opposite sides, each of which is received for support in a corresponding retaining groove of at least one part of the housing.A tongue-and-groove connection can also be provided in this way to support the retaining web.

[0020] The invention thus enables the realization of a conductor terminal block with a simple, compact design, easy assembly, and the mounting of components in only one orientation. The conductor terminal block has relatively few simple components, making assembly quick and easy. Furthermore, the conductor terminal block can be manufactured cost-effectively.

[0021] The housing can be designed, for example, as an essentially cuboid housing. The housing can be designed in exactly two parts, meaning it has only a first and second housing part. The first housing part can be connected to the second housing part, for example, via a snap-fit ​​connection. For instance, the housing can have a lower housing part and an upper housing part. The upper housing part can be designed in the form of a cap that can be placed over the lower housing part and then covers a substantial portion of the lower housing part's side walls. The aforementioned part of the housing can, for example, be the upper housing part.According to an advantageous embodiment of the invention, the conductor entry openings comprise at least one large-cross-section conductor entry opening and a number of smaller-cross-section conductor entry openings, the latter being present in greater numbers than the at least one large-cross-section conductor entry opening, wherein the at least one large-cross-section conductor entry opening has a larger cross-section than the smaller-cross-section conductor entry openings. In this way, the available area on the conductor connection side of the housing can be utilized to the best possible extent. Accordingly, only the smaller conductor entry openings are required for connecting small-cross-section conductors. Thus, the larger space requirement on the conductor connection side is only needed once, or at least only a few times, for the at least one large-cross-section conductor entry opening.

[0022] The housing of the conductor terminal, in particular the second housing part, can have an associated actuating channel for each spring-clamp terminal, in which an actuating element for opening the clamping point of the spring-clamp terminal is arranged, for example, an actuating push button. In an advantageous embodiment, the manual actuating surfaces of the actuating push buttons can be arranged on the conductor terminal side of the conductor terminal. This allows for easy operation of the spring-clamp terminals for inserting and removing electrical conductors.

[0023] For the purposes of the present invention, the indefinite term "a" is not to be understood as a numeral. Therefore, when, for example, a component is mentioned, this is to be interpreted as "at least one component". Where angles are specified in degrees, these refer to a circle of 360 degrees (360°).

[0038] Figure 16 shows the contact insert in the section plane AA,

[0039] Figure 17 shows the contact insert in the section plane BB.

[0040] Figure 1 shows a conductor terminal block 1 in the form of a distribution terminal block, which has a housing 2 with several conductor entry openings 20, 21. In the exemplary embodiments, all conductor entry openings 20, 21 are arranged on a conductor connection side 24 of the housing 2. Actuating elements 5, which extend into the interior of the housing 2, are also accessible from the outside of the conductor connection side 24. The spring-loaded terminals arranged in the housing 2 can be manually actuated via the actuating elements 5. Electrical conductors can be inserted into the housing 2 through the conductor entry openings 20, 21 and clamped to the spring-loaded terminals.

[0041] Figure 2 shows a top view of the conductor terminal 1, specifically the conductor connection side 24. It is evident that the conductor entry openings 20 and 21 have different sizes, i.e., different cross-sections. In the illustrated embodiment, there are several (here six) small-cross-section conductor entry openings 20 and one large-cross-section conductor entry opening 21. Due to their size, only electrical conductors with a smaller cross-section can be inserted into the small-cross-section conductor entry openings 20 and connected to small-cross-section spring-clamp terminals, unlike the large-cross-section conductor entry opening 21. The large-cross-section conductor entry opening 21 serves to connect a large-cross-section electrical conductor to a large-cross-section spring-clamp terminal, through which electrical energy or electrical signals are fed into or output from the conductor terminal 1.As can also be seen in Figures 1 and 2, at least one coupling element 28 can be arranged on the outside of the housing 2, e.g., on a housing lower part 23 (according to Figure 5), for example, by the coupling element 28 being integrally formed with the corresponding housing part. The housing 2 can have a corresponding counterpart to the coupling element 28 on the housing side opposite the coupling element 28. For example, the coupling element 28 can be designed as a projecting pin or locking element, in which case the counterpart on the opposite housing side can be designed as a recess or indentation in the housing 2. By means of the coupling element 28 in conjunction with its counterpart, several conductor connection terminals 1 on the outside of the housings 2 can be positively connected to each other to form a distribution strip.

[0042] The conductor terminal 1 has a busbar 3 arranged in the housing 2, which is shown in Figure 3. The busbar 3 has contact sections 31 for electrical current transmission between the various spring-clamp terminals of the conductor terminal 1. A spring support element 32 is attached to the busbar 3. The busbar 3 can be designed as a single component. This ensures optimal current flow between the spring-clamp terminals and also saves manufacturing steps. In addition, the busbar 3 also provides mechanical support for the clamping springs of at least some of the spring-clamp terminals.For this purpose, the busbar 3 has several first support elements 39, which can be shaped like projecting pins and which can, for example, be formed from the material of the busbar 3 by means of a forming process that removes material to form the pins. This creates an opening 33 in the busbar 3 near each pin.

[0043] The spring support element 32 serves to support one of the clamping springs of the conductor connection terminal 1. The spring support element 32 has a mounting section 37 with which it is attached to a retaining section 38 of the busbar 31. The spring support element 32 also has a retaining web 34, which is arranged, for example, substantially perpendicular to the mounting section 37. The retaining web 34 extends into a spring arc of the clamping spring to be supported. Retaining tabs 35 project laterally from the retaining web 34. Furthermore, the spring support element 32 has a first support element 36 extending from and beyond the retaining web 34 of the mounting section 37, with which a contact leg of the clamping spring to be supported can be positively coupled to the spring support element 32 and thus also to the busbar 3. The conductor rail 3 also has openings 8 through which support pins, which will be explained below, can extend.

[0044] Figure 4 shows the busbar 3 with clamping springs 4, 6 attached to it. There are two clamping springs 4 for the small-cross-section spring-loaded terminals, and one clamping spring 6 for the large-cross-section spring-loaded terminal. The clamping spring 6 is correspondingly larger than the clamping springs 4. Each clamping spring 4, 6 has a contact leg 41, 61. A spring arc 42, 62 is attached to the contact leg. A clamping leg 43, 63 is attached to the spring arc 42, 62. The contact leg 41, 61 serves to secure the clamping spring and to support it against the clamping force of the clamping leg 43, 63. The spring arc 42, 62 provides the necessary elasticity of the clamping spring. The spring arc 42, 62 is therefore subject to the greatest deformation when the clamping leg deflects, e.g., when the clamping point is opened.

[0045] The clamping arms 43, 63, together with a contact section 31 of the busbar 3, form a clamping point for the clamped electrical conductor(s). Furthermore, the base of the busbar, i.e., the section oriented perpendicular to the conductor insertion direction, has projecting stop tabs 30 as a stop / overload stop for the clamping arms 43, 63. The contact arms 41 can be supported by the first support elements 39, which will be explained in more detail below with reference to Figures 7 and 17. The contact arm 61 is held on one side by the retaining web 34 and on the opposite side by the first support element 36. In addition, the entire clamping spring 6 is supported by the retaining web 34, which extends inside the spring arc to the material of the clamping spring 6 and rests against it. It can also be seen that the lateral retaining tabs 35 project laterally from the clamping spring 6.

[0046] Figure 5 shows a lower housing part 23 of the housing 2 without any further elements of the conductor terminal 1 attached to it. It can be seen that support pins 7 projecting from the middle area and partially also from the edge of the lower housing part 23 are present. The support pins 7 are attached to the lower housing part 23 by a lower base section 70 or are formed integrally with it. The support pins 7 extend towards their free ends to a respective head section 72, which serves to support the clamping spring 4, as will be explained below. It can be seen that the support pins 7 have different widths in the illustrated embodiment, but they can also be formed with the same width. Figure 6 shows the lower housing part 23 with the assembly consisting of the busbar 3 and the clamping springs 4, 6 attached to it.It can be seen that the support mandrels 7, with their head sections 72, which have a rounded end, now extend into the respective spring arches 42 and bear against them. Between the spring arches 42 of the adjacent clamping springs arranged in a row, there is a gap which is bridged by at least one of the head sections 72 arranged in the middle. Such a head section 72 extends from the spring arch 42 of one clamping spring to the spring arch 42 of the adjacent clamping spring. In this way, the centrally arranged support mandrels 7, with their respective head sections 72, function as support elements for each pair of adjacent clamping springs 4.

[0047] The sectional view in Figure 7 further illustrates the support of the clamping springs 4 by the respective support mandrel 7, in that the head section 72 of the support mandrel 7 extends into the spring arch 42 and bears against it at least partially. The contact leg 41 of the clamping spring 4 can advantageously bear against the support mandrel 7 over at least most of its length. In addition, the free ends of the contact legs 41 can bear against the first support elements 39, which are made of the same material as the first support elements projecting from the openings 33. A first support element 39 serves as a support for two opposing clamping springs 4.

[0048] Figure 8 illustrates that the respective outer support pins 7 support the outermost clamping spring 4 or spring arch 42 on one side. The middle support pins 7 each support two adjacent spring arches 42 at their lateral edges.

[0049] The sectional view in Figure 9 illustrates that, with the upper housing part 22 in place, the areas of the head sections 72 and partially also of the base sections 70 of the support mandrels 7 that project laterally beyond the clamping springs 4 are positively engaged in a receiving groove 26 of the upper housing part 23 adapted in size and thus supported.

[0050] The sectional view in Figure 10 illustrates the design of the spring-loaded clamping connection with its large cross-section. In particular, it clarifies the position and fixation of the clamping spring 6 by means of the retaining web 34 and the first support element 36. Advantageously, the contact leg 61 can bear against the retaining web 34 over a significant portion of its length. Figure 11 illustrates the fixation and support of the retaining web 34 by the lateral retaining tabs 35, each of which engages in a retaining groove 27 of the upper housing part 22 and is positively engaged therein.

[0051] Figure 12 shows a clamping spring 6 for a large-cross-section spring-loaded clamping connection. In addition to the clamping leg 63 and spring arc 62 already described, it can be seen that the contact leg 61 is divided into a main section 64 and two contact projections 65 extending from it. The contact projections 65 extend from the free end of the main section 64 in a direction away from the clamping leg 63. Each contact projection 65 has a sharp contact edge 66 at its free end facing away from the clamping leg 63. A space is formed between the contact projections 65. A first contact point 67 of the contact leg 61 is located there, which serves to contact the first support element 36 for support against the conductor rail 3.

[0052] Figure 10 shows the double support of the mounting leg 61 via the first contact point 67 formed on the mounting leg 61, which is supported on a first support element 36 on the busbar 3. Furthermore, the second support is shown via the contact projections 65, which are supported on a second support element 29 on the insulating housing 2. This will be further illustrated below with reference to Figures 14 and 16.

[0053] Figure 13 shows a clamping spring 4 for a small-section spring-loaded clamping connection. In addition to the clamping leg 43 and spring arc 42 already described, it can be seen that the contact leg 41 is divided into a main section 44 and two contact projections 45 extending from it. The contact projections 45 extend from the free end of the main section 44 in a direction away from the clamping leg 43. Each contact projection 45 has a sharp contact edge 46 at its free end facing away from the clamping leg 43. A space is formed between the contact projections 45. A first contact point 47 of the contact leg 41 is located there, which serves to contact the first support element 39 on the conductor rail 3.

[0054] Figure 14 shows the conductor connection terminal 1 in the same sectional view in section plane AA as in Figure 10, with the busbar 3 not shown to illustrate the support of the clamping spring 6. Instead, an enlarged detail is shown below, illustrating the support of the contact leg 61, or its main section 64, via the respective contact projection 65 on a second support element 29 of the insulating housing 2. It can be seen that the contact edge 67 is slightly embedded in the material of the insulating housing 2.

[0055] Figure 15 shows the conductor terminal 1 in the same sectional view in section plane BB as in Figure 7, again omitting the busbar 3. It can be seen that two clamping springs 4 are arranged back-to-back. The enlarged detail shown below further illustrates that both clamping springs 4, with their contact legs 41 and their main sections 44 respectively, are supported by the respective contact projection 45 on opposite sides of the same second support element 29 of the insulating housing 2. It can be seen that the contact edges 47 are slightly embedded in the material of the insulating housing 2.

[0056] Figure 16 illustrates the support of the mounting leg 61 on the conductor rail 3, in that the first contact point 67 of the mounting leg 61 rests against the first support element 36.

[0057] Figure 17 illustrates the support of the two clamping springs 4 with their contact legs 41 on the common first support element 39 arranged between the contact legs 41, on which the first contact points 47 of the contact legs 41 abut opposite sides.
