Description

[0001] The invention relates to a conductor terminal, the use of a conductor terminal, and a method for mounting a conductor terminal. Conductor terminals can, in particular, be terminals that serve for the detachable connection or joining of electrical conductors and, in the clamped state, can ensure electrical contact of the conductor by mechanically fixing the connected conductor. The conductor terminals can be spring-clamp terminals, which are also called, for example, push-in terminals, spring clamps, cage clamps, or spring-loaded clamps.

[0002] Conductor terminals are known in which a contact insert can be inserted into a laterally open recess in a housing, and this recess can be closed with a cover. A conductor terminal in the form of a push-in wire connector is known from DE 10 2008 032 276 A1.

[0003] Against this background, the object of the invention is to create an improved conductor terminal block with a simplified design, easier assembly and higher operational reliability.

[0004] The problem is solved by a conductor terminal according to claim 1, by using a conductor terminal according to claim 11, and by a method for mounting a conductor terminal according to claim 12. Advantageous embodiments are disclosed in the dependent claims, the description, and the figures.

[0005] The conductor terminal has a contact insert which has a busbar and a clamping spring, and a housing comprising a first housing part and a second housing part which at least partially encloses the contact insert, wherein the first housing part has a first housing wall with a receiving structure for receiving the contact insert and the second housing part has several further housing walls for covering the contact insert received by the first housing part.

[0006] The housing at least partially encloses the contact insert. The housing can completely enclose or fully enclose the contact insert. The housing protects the contact insert, for example, from environmental conditions and from accidental or unauthorized access. The housing provides electrical insulation between the contact insert and its environment and can therefore be made of an insulating material such as plastic. The housing consists of at least two parts: a first and a second housing section, and can be assembled with these two sections, as well as any additional sections, to form a complete housing. The first and second housing sections can, for example, be joined along a connecting line. The housing walls can be flush with each other at this connecting line.

[0007] The first housing part has a receiving structure for the contact insert. This receiving structure can, for example, be a form integrated with the first housing part, such as a mounting or insert structure. The receiving structure can include, for example, material projections, support elements, negative contours of the contact insert, fastening structures such as clips, or other means for a positive-locking and / or force-locking connection between the first housing part and the contact insert, particularly a detachable one. The receiving structure can, for example, include a spring carrier. The receiving structure can enable the contact insert to be fixed by reducing selected degrees of freedom. The receiving structure can simplify the positioning and assembly of the contact insert on the first housing part by means of a predefined mounting or insert structure.The first housing part can also be referred to as the base or foundation housing.

[0008] The second housing part has multiple walls. The main dimensions of the walls can run in different planes. For example, adjacent walls can be essentially perpendicular to each other. Walls of the second housing part can also be opposite each other and essentially parallel. Some or all walls can be solid. Some or all walls can have openings. The second housing part can also be called a lid housing. Typically, in the assembly process of a housing with a base housing and a lid housing, the lid housing is placed on top of the base housing, which is why the second housing part can be described as a lid housing in this case.At the same time, the second housing part differs from a simple housing cover, which usually only has one housing wall, as is known from the prior art, by the feature of having several housing walls.

[0009] The conductor terminal block features a simplified design, facilitating easy assembly. The mounting structure of the first housing wall of the first housing section is easily accessible, allowing for quick and secure mounting of the contact insert. The second housing section can be securely and quickly positioned and connected to the first. The contact insert is covered by multiple housing walls of the second section, ensuring compliance with the required clearances and creepage distances for the operational reliability of the conductor terminal block.

[0010] According to the invention, the receiving structure has at least one frame wall projecting substantially transversely from the first housing wall, which, together with the first housing wall, defines a receiving space for the contact insert. This provides a housing wall with a receiving structure that enables a defined insertion of the contact insert. The receiving space defines and visualizes the intended mounting position of the contact insert. The frame wall can reduce the degrees of freedom of movement of the contact insert. Due to the limited receiving space, the mounting of the conductor terminal is safer and easier. The frame wall can also provide improved mechanical protection and support the electrical insulation of the contact insert. The frame wall can be offset below the edge or a finishing edge of the first housing wall, forming a step, to create a receiving area for a housing wall of the second housing part.

[0011] It is advantageous if the frame wall extends along one longitudinal side of the contact insert. One longitudinal side of the contact insert can run essentially parallel to the insertion direction of an electrical conductor into the terminal block. One end face of the contact insert can run essentially perpendicular to the insertion direction of an electrical conductor into the terminal block. The contact insert can, for example, have four longitudinal sides and two end faces. The assembled housing can also, for example, have four longitudinal sides and two end faces. Extending the frame wall along one longitudinal side of the contact insert facilitates intuitive assembly of the contact insert and improves mechanical protection and insulation along its length.

[0012] It is advantageous if each frame wall extends along a lower side of the contact insert facing the busbar and / or along a higher side of the contact insert facing away from the busbar. A lower side and a higher side of the contact insert can each correspond to a longitudinal side of the contact insert. For example, a busbar of the contact insert can be arranged on a lower side. A higher side can be a side or longitudinal side of the contact insert opposite the lower side or running substantially parallel to the lower side. In one embodiment, the first housing wall can have two frame walls. The frame walls can define a receiving space for the contact insert.The receiving space can be bounded on three sides parallel to the insertion direction of an electrical conductor by walls: the first housing wall and two frame walls. Extending a frame wall along the top or bottom of the contact insert facilitates intuitive installation. Extending a frame wall along both the top and bottom of the contact insert improves mechanical protection and insulation along its length. This also more precisely defines and delimits the receiving space for the contact insert.

[0013] It is advantageous if the second housing part has at least three housing walls to cover the contact insert and / or the first housing part. This improves the covering function of the second housing part. At least one of the at least three housing walls can run substantially parallel to a longitudinal side and / or substantially parallel to an end face of the contact insert. Any two of the at least three housing walls can be arranged substantially perpendicular to each other. The second housing part can, in particular, also have at least four or at least five housing walls to cover the contact insert and / or the first housing part. For example, the second housing part can have three housing walls running substantially parallel to each of the longitudinal sides of the contact insert and two housing walls running substantially parallel to each of the end faces of the contact insert.

[0014] It is advantageous if, in the assembled state of the housing, at least one housing wall of the second housing part partially or completely overlaps a frame wall of the first housing part. For example, in the assembled state of the housing, at least one housing wall of the second housing part can overlap a frame wall of the first housing part with an overlap of more than 50%, in particular more than 70%, and further, in particular more than 80%, where the overlap can be the percentage of the sum of the mutually facing and overlapping areas of the housing wall and the frame wall relative to the sum of the total mutually facing areas of the housing wall and the frame wall. Thus, a housing wall of the second housing part and a frame wall of the first housing part can overlap at least partially.With an overlap, mechanical contact can be established between a housing wall and a frame wall, meaning their opposing surfaces touch. The overlapping frame and housing walls can, for example, extend essentially parallel to each other. In this overlap, the housing wall of the second housing part can form the outer wall facing the environment, and the frame wall of the first housing part can form the inner wall facing the contact insert. This allows the cover housing to be easily placed or slid onto the base housing. Depending on the requirements, the overlap can also be a clearance fit, transition fit, or interference fit between a housing wall and a frame wall. The overlap creates a local double wall through the first and second housing parts, thereby improving the mechanical protection and electrical insulation of the conductor terminal.Furthermore, the intended overlap provides a predetermined mounting arrangement and orientation of the first and second housing parts relative to each other, thereby simplifying assembly.

[0015] It is advantageous if the first and second housing parts each have a U-shaped cross-section, whereby, in the assembled state of the housing, the U-shaped legs of the second housing part interlock with the U-shaped legs of the first housing part, and the U-shaped legs of the first housing part interlock with the contact insert. The second housing part, acting as a cover, can have a larger U-shaped cross-section than the first housing part, acting as the base housing. This allows the cover to be placed or slid onto the base housing, and, in the assembled state, the cover overlaps the base housing on several sides. This enables a simple design of the conductor connection terminal with intuitive and simplified assembly. The interlocking U-shaped legs of the first and second housing parts create a positive fit, ensuring a secure mechanical connection between the housing parts.Furthermore, the contact insert is securely embedded within the cross-section of both housing parts. By accommodating the U-shaped legs of the first housing part between the U-shaped legs of the second housing part, double walls are formed locally in the area where the U-shaped legs overlap, thus improving the mechanical protection and electrical insulation of the conductor terminal.

[0016] It is advantageous if the second housing part has an end wall for covering the housing at the end. In particular, the second housing part can have two end walls for covering the housing at the end on two opposite ends of the housing. An end wall can extend substantially transversely to the insertion direction of an electrical conductor into the terminal block. An end wall can extend substantially transversely to a longitudinal side of the housing. An end face of the housing can run substantially parallel to an end face of the contact insert placed in the housing. An end face of the housing can be a side through which a conductor inserted into the terminal block enters the housing. An end face of the housing can have a smaller surface area than a longitudinal side of the housing.A housing end wall can be a wall of the housing or housing part. A housing end wall improves the covering function of the second housing part in the end-face area of ​​the inserted contact insert. Alternatively or additionally, the first housing part or base housing can also have one or more housing end walls. A housing end wall of the first housing part can at least partially cover or overlap a housing end wall of the second housing part. One or more housing end walls can have an opening, for example, a conductor entry opening.

[0017] It is advantageous if the conductor terminal is a double terminal for two electrical conductors that can be inserted into it in separate directions. These insertion directions can, for example, be opposite to each other. This allows two conductors to be connected to the conductor terminal without requiring significant additional installation space or design complexity. For example, the contact insert can have two opposing clamping springs and a common busbar for both spring-loaded terminals. The housing of the conductor terminal can, for example, have two opposing end walls with conductor entry openings. In other embodiments, it is conceivable to connect more than two electrical conductors to the conductor terminal.

[0018] It is advantageous if a partition wall projects transversely from the frame wall and / or the first housing wall. This allows for or improves the spatial separation of two or more conductor connection compartments for spring-clamp terminals. The second housing part can have a partition wall recess, which is designed, for example, as two spaced-apart, wall-like material projections between which the partition wall can be inserted. This increases the stability of the conductor connection terminal and simplifies assembly, as the partition wall recess can serve as a guide and orientation for positioning the first and second housing parts relative to each other. The partition wall and the partition wall recess can also be detachably connected to each other by means of a snap-fit ​​connection to improve the connection between the first and second housing parts.The insulation of the conductor connection spaces from each other is further improved by a wall-like partition wall.

[0019] According to the invention, one or more frame walls have a frame recess that runs parallel to a housing wall recess of the second housing part and together they form a grip recess. The grip recess can facilitate gripping the conductor terminal or, for example, also indicate the top or bottom side of the conductor terminal.

[0020] It is advantageous if the frame wall has a support block projecting transversely from it. This allows, for example, the end face of a contact insert to be supported or its axial movement to be limited. The support block can define the receiving space for the contact insert more precisely. The support block also increases the stability of the first housing part. The frame wall can also have two or more support blocks projecting transversely from it. The support block(s), together with one or more frame walls and the first housing wall of the first housing part, can form a receiving structure or an inner housing for the defined receiving of the contact insert.

[0021] The support block can have a conductor entry channel. This improves the guidance of an inserted electrical conductor and simplifies the operation of the conductor connection terminal.

[0022] It is advantageous if the contact insert and / or the housing have a symmetrical design. This further simplifies the construction of the conductor connection terminal. Furthermore, assembly is facilitated, as, for example, the contact insert can be inserted into the first housing part in more than one orientation. The axis of symmetry can, for instance, coincide with a central axis of the contact insert or the housing, which runs through the spatial center of the contact insert or the housing.

[0023] It is advantageous if the first and second housing parts are interlocked, riveted, and / or welded together when the housing is assembled. This ensures a secure connection between the first and second housing parts and increases the stability of the conductor terminal.

[0024] It is advantageous if the first housing part has a first conductor entry channel section and the second housing part has a second conductor entry channel section, whereby, in the assembled state of the housing, the first and second conductor entry channel sections together form a conductor entry channel for inserting an electrical conductor. This shared design of the conductor entry channel increases its stability and expandability. Furthermore, the assembly of the conductor terminal block is simplified and intuitive, since the conductor entry channel sections only need to be positioned adjacent to each other when joining the first and second housing parts. Additionally, the manufacturing of the first and second housing parts is simplified if each part has only one conductor entry channel section, thus requiring, for example, fewer undercuts.The first conductor entry channel section can be associated with the main housing of the terminal block, and the second conductor entry channel section can be associated with the cover housing of the terminal block. The first conductor entry channel section can form an inner section of the conductor entry channel, facing the receiving space or contact insert, and the second conductor entry channel section can form an outer section of the conductor entry channel, facing the environment. The second conductor entry channel section can have a conductor entry opening accessible from outside the terminal block.

[0025] It is advantageous if the first conductor entry channel section and / or the second conductor entry channel section is essentially or predominantly closed around its circumference. In particular, the first conductor entry channel section and / or the second conductor entry channel section can be closed around its circumference by more than 180°, especially more than 270°. The first conductor entry channel section and / or the second conductor entry channel section can thus have an essentially closed cross-section. This results in a more precise delimitation of the conductor entry channel and increases the stability of the conductor terminal in the conductor entry area. Safe and intuitive insertion of an electrical conductor into the conductor entry channel is then possible.If the first conductor entry channel section and the second conductor entry channel section are essentially closed on their circumference, the area of ​​the first housing part and the second housing part adjacent to the conductor entry channel can be at least partially covered, so that the at least partial covering results in increased stability and better insulation of the contact insert by the housing.

[0026] The first conductor entry channel section can be positioned downstream of the second conductor entry channel section in the direction of conductor insertion. When an electrical conductor is inserted, it therefore first passes through the second conductor entry channel section and then through the first conductor entry channel section.

[0027] It is advantageous if the housing has a conductor entry opening for inserting an electrical conductor, which is formed on the second conductor channel section. The conductor entry opening defines the insertion area of ​​the electrical conductor into the housing and is therefore visible from the outside. For example, in the case of a conductor entry channel that tapers in the direction of conductor insertion, the conductor entry opening can form a section of the largest cross-section of the conductor entry channel. A housing wall, in particular an end wall of the second housing part or cover housing, can enclose or frame the conductor entry opening. The conductor entry opening can be designed as a penetration through a housing wall or end wall of the second housing part or cover housing.

[0028] The task can also be accomplished by using a conductor terminal with one of the aforementioned features as a repair terminal for connecting sections of a severed electrical conductor or two free conductor ends. Due to its simple design, ease of assembly, and high insulating capacity, this conductor terminal is particularly suitable for use in repair applications.

[0029] The problem is also solved by a method for assembling a conductor terminal block with a contact insert having a busbar and a clamping spring, and with a housing comprising a first housing part and a second housing part that at least partially encloses the contact insert. In this method, the contact insert is inserted into the first housing part, and then the second housing part, which has multiple housing walls, is placed on top of the first housing part and connected to it. This provides a method that enables particularly simple, quick, and intuitive assembly of a conductor terminal block. By covering the contact insert with multiple housing walls of the second housing part, compliance with the required clearances and creepage distances for the operational reliability of the conductor terminal block is ensured. The first housing part can be a base housing, and the second housing part can be a cover housing.The contact insert can be inserted, in particular, into a receiving space of the first housing part formed by a first housing wall and a frame wall projecting transversely from the first housing wall. By arranging the second housing part on the first housing part, a common conductor entry channel can be formed, in particular, from a first conductor entry channel section of the first housing part and a second conductor entry channel section of the second housing part. The contact insert can be formed in an upstream process step by assembling at least one busbar and at least one clamping spring. The contact insert can, in particular, be pre-assembled.

[0030] It is advantageous if the insertion direction of the contact insert into the first housing part is perpendicular to its longitudinal direction. The longitudinal direction of the contact insert can essentially run parallel to a conductor insertion direction. During assembly, the contact insert is not inserted or pushed into the housing with one end facing forward in a conductor insertion direction or opposite to it, but rather moved perpendicular to this direction towards the first housing part and positioned, for example, on a receiving structure and / or in a receiving space of the first housing part. This enables simple and quick assembly of the conductor connection terminal. It is also advantageous if the arrangement of the second housing part on the first housing part is in a mounting direction that corresponds to, or runs parallel to, the insertion direction of the contact insert into the first housing part.

[0031] It is advantageous if a conductor terminal block is mounted using this method according to one of the features described above.

[0032] In general, in the context of this application, the words "ein / eine" (a / an) are not to be understood as numerals, unless explicitly defined otherwise, but as indefinite articles meaning "at least one / an". All angle measurements refer to a circle of 360°.

[0033] The invention is explained in more detail below with reference to an exemplary embodiment and the accompanying drawings. These show, in schematic form: Fig. 1 - a perspective front view of a first housing part; Fig. 2 - a perspective rear view of the first housing part; Fig. 3 - a perspective front view of a second housing part; Fig. 4 - another front view of the second housing part; Fig. 5 - a perspective bottom view of the second housing part; Fig. 6 - a sectional view of a conductor terminal with inserted contact insert and assembled housing; Fig. 7 - a perspective sectional view of the conductor terminal with inserted contact insert and assembled housing; Fig. 8 - a perspective rear view of the conductor terminal with assembled housing; Fig. 9 - a sectional side view of the conductor terminal with inserted contact insert and assembled housing; Fig. 10 - a perspective sectional side view of the conductor terminal with inserted contact insert and assembled housing; Fig.11 - a contact insert for a conductor terminal; Fig. 12 - a method for mounting a conductor terminal.

[0034] Figure 1 shows a front view of a first housing part 5A for, for example, a housing in the Figures 6 to 10 The conductor connection terminal 1 shown, designed as a double terminal, is located there. The first housing part 5A can be connected, for example, to the Figures 3 to 5 The second housing part 5B shown can be assembled to form a housing 5 of the conductor connection terminal 1. In the illustrated embodiments, the housing 5 of the conductor connection terminal 1 is constructed in two parts, consisting of the first housing part 5A and the second housing part 5B. It is also conceivable to assemble the housing 5 of the conductor connection terminal 1 from more than two housing parts. The housing 5 of the conductor connection terminal 1 is designed to accommodate, for example, a Figure 6 , 7 and 11The contact insert 2 shown is to be at least partially enclosed by a busbar 3 and one or more clamping springs 4 in order to protect the contact insert 2 from environmental conditions and to provide electrical insulation of the contact insert 2 from the environment.

[0035] The first housing part 5A has a first housing wall GW 1 with a receiving structure 6 for receiving the contact insert 2. In the illustrated embodiments, the receiving structure 6 is formed by several structural elements such as frame walls 7 (described below), a partition 10, spring carriers, and support blocks 12. However, it is also conceivable to provide more or fewer structural elements to form the receiving structure 6.

[0036] Two frame walls 7 project essentially vertically from the first housing wall GW 1 and, together with the first housing wall GW 1, define a receiving space 8 for the contact insert 2. The frame walls 7 extend along the longitudinal sides of the contact insert 2 to be inserted. In the illustrated embodiment, each frame wall 7 extends along one of the sides facing the busbar 3 of the contact insert 2. Figure 11 shown underside Ku of contact insert 2 and along one of the busbars of contact insert 2 facing away from the busbar, in Figure 11 The top surface Ko of the contact insert 2 is shown. One of the two frame walls 7 shown has a frame recess 16A, which is parallel to a housing wall recess 16B, for example. Fig. 3) of the second housing part 5B and together they form a grip recess. The grip recess can facilitate gripping the conductor terminal 1 and, in the illustrated embodiments, visualize a top side of the conductor terminal 1 facing away from the busbar 3 of the contact insert 2.

[0037] A partition 10 projects essentially perpendicularly from the first housing wall GW 1 and from one of the frame walls 7. This partition serves, among other things, to spatially separate and electrically insulate two adjacent connection compartments for electrical conductors. In this embodiment, the partition 10 defines a central area of ​​the first housing part, from which a spring-loaded terminal for an electrical conductor can be provided on both the left and right sides. For this purpose, an electrical conductor can be inserted into the conductor terminal 1 in each of these directions R EF.

[0038] Support blocks 12 project from the frame walls 7, further limiting the receiving space 8 for the contact insert 2 and reducing or preventing translational movement of the contact insert 2 in the same or opposite direction to the insertion direction R EF.

[0039] Furthermore, on the first housing part 5A, a first conductor entry channel section 13A is formed for each side of the double terminal, which in the assembled state of the housing 5 together with, for example, a Figure 3 The second conductor entry channel section 13B of the second housing part 5B shown forms a conductor entry channel 13.

[0040] In Figure 2The first housing part 5A is shown in a rear view. It can be seen, for example, how one of the frame walls 7 projects essentially perpendicularly from the first housing wall GW 1. Here, the frame wall 7 is slightly offset inwards, meaning its surface is not flush with an edge of the first housing wall GW 1. The resulting recess 17 between the frame wall 7 and the edge of the first housing wall GW 1 forms a receiving area for a housing wall of the second housing part 5B, for example, the fourth housing wall GW 4.

[0041] Figure 3Figure 1 shows a front view of a second housing part 5B for the conductor terminal 1. The second housing part 5B has several housing walls, namely, in the illustrated embodiment, a second housing wall GW 2, a third housing wall GW 3, a fourth housing wall GW 4, and two housing end walls GWs. The housing walls GW 2, GW 3, GW 4, and GWs serve to at least partially cover the contact insert 2 of the conductor terminal 1 and, together with the first housing wall GW 1 of the first housing part 5A, form the housing 5 of the conductor terminal 1 when the first and second housing parts 5A and 5B are assembled. The second housing part 5B acts as a cover housing and is designed to be placed on top of the first housing part 5A after a contact insert 2 has been installed in it.The housing walls GW 1, GW 2, GW 3, GW 4 can be assigned to the longitudinal sides of the conductor terminal 1, the housing 5, or the contact insert 2, while the housing end walls GWs can be assigned to the end faces of the conductor terminal 1, the housing 5, or the contact insert 2. The housing end walls GWs of the second housing part 5B each have an opening that forms a conductor entry opening 14 and a second conductor entry channel section 13B. An electrical conductor, in the illustrated embodiment, can be inserted into the housing 5 from opposite end faces of the second housing part 5B in a conductor entry direction R EF into the housing 5 via the conductor entry opening 14 and the adjoining second conductor entry channel section 13B.

[0042] The second housing part 5B has a partition receptacle 11 in the form of two spaced-apart, wall-like material projections, between which the partition 10 of the first housing part 5A can be inserted. The second housing part 5B has a housing wall recess 16B, which, when the housing 5 is assembled, covers a frame recess 16A of the first housing part 5A and together they form a handle recess.

[0043] The Figures 4 and 5 The second housing part 5B is shown in a further front view and a bottom view for closer illustration.

[0044] Figure 6Figure 1 shows the conductor terminal 1 in an assembled state, i.e., with an inserted contact insert 2 and the housing 5, formed from the first housing part 5A and the second housing part 5B, enclosing the contact insert 2. Visible are the contact insert 2 with a busbar 3 and two clamping springs 4 for two spring-clamp connections of two electrical conductors (not shown) that can be inserted into the conductor terminal 1 in the insertion direction R EF. It can be seen that the third housing wall GW 3 and the fourth housing wall GW 4 of the second housing part 5B cover the frame walls 7 of the first housing part 5A, thus providing double-wall construction that increases the insulation and stability of the conductor terminal 1.It can also be seen that the first conductor entry channel section 13A of the first housing part 5A and the second conductor entry channel section 13B of the second housing part 5B together form a conductor entry channel 13 for inserting an electrical conductor starting from the conductor entry opening 14 of the second housing part 5B. The support blocks 12 additionally have a conductor entry channel area 18 for continuing the conductor entry channel 13. Furthermore, it becomes clear how the receiving structure 6 of the conductor connection terminal 1, with several structural elements such as spring carriers, the partition wall receptacle 11, the frame walls 7, and the support blocks 12, defines a delimited receiving space for the contact insert 2, so that it is securely held in the housing 5 and assembly is facilitated.Furthermore, it can be seen that the partition 10 is inserted between the material projections of the partition receptacle 11, which also facilitates the positioning and fixing of the first housing part 5A and the second housing part 5B to one another. The symmetrical design of the conductor connection terminal 1 is also evident, with a symmetry axis (not shown) running perpendicular to the insertion direction R EF through the partition 10.

[0045] The conductor terminal 1 has a simplified design, facilitating its assembly. The mounting structure 6 of the first housing wall GW 1 of the first housing part 5A is easily accessible, enabling quick and secure mounting of the contact insert 2 to the first housing part 5A. The second housing part 5B can be securely and quickly positioned and connected to the first housing part 5A. The contact insert 2 is covered by several housing walls GW 2, GW 3, GW 4, and GW S of the second housing part 5B, ensuring compliance with the required clearances and creepage distances for the operational reliability of the conductor terminal 1.

[0046] Figure 7 shows the representation of conductor connection terminal 1 from Figure 6For further illustration, a perspective view is shown. Additionally, the longitudinal direction R LE of the contact insert 2 is indicated by a double arrow. When mounting the conductor terminal 1, the contact insert 2 is inserted into the first housing part 5A perpendicular to this longitudinal direction R LE in an insertion direction R ES.

[0047] Figure 8Figure 1 shows a perspective rear view of the conductor terminal 1 with the assembled housing 5. It can be seen that the housing parts 5A and 5B are joined along a connecting line 15. At connecting line 15, the first housing wall GW 1 of the first housing part 5A and the fourth housing wall GW 4 of the second housing part 5B merge seamlessly. A similar situation exists on the opposite side at the transition between the first housing wall GW 1 and the third housing wall GW 3. The first housing part 5A and the second housing part 5B can also be, for example, snapped, riveted, and / or welded together when the housing 5 is assembled.

[0048] Figure 9Figure 1 shows a cutaway side view of the conductor terminal 1 with the contact insert 2 inserted and the housing 5 assembled from housing parts 5A and 5B. In this view, it can be seen that the first housing part 5A and the second housing part 5B each have a U-shaped cross-section in the illustrated embodiment, wherein, in the assembled state of the housing 5, the U-legs 9B of the second housing part 5B accommodate the U-legs 9A of the first housing part 5A between them, and the U-legs 9A of the first housing part 5A accommodate the contact insert 2 between them.

[0049] Figure 10 shows the cutaway view of conductor terminal 1. Figure 9 for supplementary illustration in a perspective view.

[0050] Figure 11Figure 1 shows a pre-assembled contact insert 2 for the conductor terminal 1 in a perspective view. The contact insert 2 has a busbar 3, on the ends of which a clamping spring 4 is mounted to form a spring-loaded clamp connection with an electrical conductor.
