Description

[0001] The invention relates to a conductor connection terminal, the use of a conductor connection terminal and a method for assembling a conductor connection terminal.

[0002] Conductor connection terminals can, in particular, be terminals that are used for the detachable connection or connection of electrical conductors and, when clamped, can ensure electrical contact of the conductor by mechanically securing the connected conductor. Conductor connection terminals can be spring-loaded terminals, which are also called plug-in terminals, spring terminals, cage clamp terminals, or spring-loaded terminals.

[0003] Conductor connection terminals are known in which a contact insert can be inserted into a laterally open recess of a housing and this recess can be closed with a cover.

[0004] Against this background, the object of the invention is to create an improved conductor connection terminal with a simplified structure, easier assembly and greater operational reliability.

[0005] The object is achieved with a conductor terminal according to claim 1, with a use of a conductor terminal according to claim 20, and with a method for assembling a conductor terminal according to claim 21. Advantageous embodiments are disclosed in the subclaims, the description, and the figures.

[0006] The conductor connection terminal has a contact insert having a busbar and a clamping spring, and a housing having 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 a plurality of further housing walls for covering the contact insert received by the first housing part.

[0007] The housing at least partially encloses the contact insert. The housing can completely enclose or surround the contact insert. The housing protects the contact insert, for example, from environmental conditions and from accidental or unauthorized access to the contact insert by a person. The housing enables electrical insulation of the contact insert from the environment and can therefore be made of an insulating material such as a plastic. The housing is constructed in at least two parts, with a first and a second housing part, and can be assembled with the first, the second and optionally further housing parts to form a complete housing. The first and second housing parts can, for example, be assembled along a connecting line. Housing walls can merge flush into one another at the connecting line.

[0008] The first housing part has a receiving structure for receiving the contact insert. The receiving structure can, for example, be a receiving shape formed integrally with the first housing part, which can be designed, for example, as an attachment or insert structure. The receiving structure can, for example, have material projections, support elements, negative contours of the contact insert, fastening structures such as clip receptacles, or other means for, in particular, a releasable, positive-locking and / or non-positive connection of the first housing part to the contact insert. The receiving structure can, for example, have a spring carrier. The receiving structure can enable the received contact insert to be fixed by reducing selected degrees of freedom of movement. The receiving structure can simplify the positioning and assembly of the contact insert on the first housing part through a predetermined attachment or insert structure.The first housing part can also be called the base or basic housing.

[0009] The second housing part has several housing walls. The main extensions of the housing walls can run in different planes. For example, adjacent housing walls can be essentially perpendicular to one another. For example, housing walls of the second housing part can lie opposite one another and run essentially parallel to one another. Some or all of the housing walls can be solid-surface. Some or all of the housing walls can have openings. The second housing part can also be referred to as a cover housing. In a typical assembly process for a housing with a base housing and a cover housing, the cover housing is usually finally placed onto the base housing, which is why the second housing part can be described as a cover housing in this case.At the same time, the second housing part differs from a simple housing cover, which usually has only one housing wall, as is known from the prior art, by the feature of several housing walls.

[0010] The conductor connection terminal has a simplified design and enables easier installation. The receiving structure of the first housing wall of the first housing part is easily accessible and enables quick and secure installation of the contact insert on the first housing part. The second housing part can be securely and quickly arranged on the first housing part and connected to it. By covering the contact insert with several housing walls of the second housing part, compliance with the required clearance and creepage distances for the operational reliability of the conductor connection terminal is ensured.

[0011] It is advantageous if the receiving structure has at least one frame wall which projects essentially transversely from the first housing wall and which, together with the first housing wall, delimits a receiving space for the contact insert. This provides a housing wall with a receiving structure which enables defined use of the contact insert. The receiving space delimits and visualizes the intended mounting location for the contact insert. The frame wall can reduce the degrees of freedom of movement of the contact insert. The limited receiving space makes installation of the conductor connection terminal 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 terminal edge of the first housing wall to form a shoulder in order to create a receiving area for a housing wall of the second housing part.

[0012] It is advantageous if the frame wall extends along a long side of the contact insert. One long side of the contact insert can run essentially parallel to a direction of insertion of an electrical conductor into the conductor connection terminal. One end face of the contact insert can run essentially transverse to a direction of insertion of an electrical conductor into the conductor connection terminal. The contact insert can, for example, have four long sides and two end faces. The assembled housing can also, for example, have four long sides and two end faces. By running the frame wall along a long side of the contact insert, intuitive assembly of the contact insert is supported and mechanical protection and insulation over the length of the contact insert is improved.

[0013] It is advantageous if a frame wall extends along a bottom side of the contact insert facing the busbar of the contact insert and / or along a top side of the contact insert facing away from the busbar of the contact insert. A bottom side and a top side of the contact insert can each correspond to a long side of the contact insert. For example, a busbar of the contact insert can be arranged on a bottom side. A top side can be a side or long side of the contact insert opposite the bottom side or running essentially parallel to the bottom side. In one embodiment, the first housing wall can have two frame walls. The frame walls can delimit a receiving space for the contact insert.The receiving space can be defined by walls on three sides extending parallel to the insertion direction of an electrical conductor, namely the first housing wall and two frame walls. A frame wall running along a top or bottom side of the contact insert supports intuitive assembly of the contact insert. A frame wall running along a top and bottom side of the contact insert improves mechanical protection and insulation along the length of the contact insert. Furthermore, a receiving space for the contact insert is more precisely defined and delimited.

[0014] It is advantageous if the second housing part has at least three housing walls for covering 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 essentially parallel to a long side and / or essentially parallel to an end face of the contact insert. Two of the at least three housing walls can be arranged essentially perpendicular to one another. The second housing part can in particular also have at least four or at least five housing walls for covering the contact insert and / or the first housing part. The second housing part can, for example, have three housing walls that run essentially parallel to a long side of the contact insert and two that run essentially parallel to an end face of the contact insert.

[0015] It is advantageous if, in the assembled state of the housing, at least one housing wall of the second housing part partially or completely covers 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 cover a frame wall of the first housing part with a degree of overlap of more than 50%, in particular more than 70%, further in particular more than 80%, wherein the degree of overlap can be the percentage share of the sum of the mutually facing and overlapping surfaces of the housing wall and the frame wall of the sum of the mutually facing total surfaces 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 at least partially overlap.The overlap can result in mechanical contact between a housing wall and a frame wall, meaning they touch at their mutually facing surfaces. The overlapping frame and housing walls can, for example, extend essentially parallel to one another. With the 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 pushed onto the base housing. Depending on requirements, the overlap can also be a clearance fit, transition fit, or interference fit of a housing wall with a frame wall. The overlap creates a double wall locally through the first and second housing parts, which improves the mechanical protection and electrical insulation of the conductor connection terminal.In addition, the intended overlap provides a predetermined assembly arrangement and orientation of the first and second housing parts to each other, thereby simplifying assembly.

[0016] It is advantageous if the first housing part and the second housing part each have a U-shaped cross-section, whereby when the housing is assembled, the U-legs of the second housing part accommodate the U-legs of the first housing part between them and the U-legs of the first housing part accommodate the contact insert between them. The second housing part as the cover housing can have a larger U-shaped cross-section than the first housing part as the base housing, so that the cover housing can be placed or pushed onto the base housing and the cover housing engages over the base housing on several sides when the housing is assembled. This enables a simple design of the conductor connection terminal with intuitive and simplified assembly. The interlocking U-legs of the first and second housing parts create a positive fit that enables a secure mechanical connection of the housing parts.In addition, the contact insert is securely enclosed in the cross-section of both housing sections. By accommodating the U-shaped legs of the first housing section between the U-shaped legs of the second housing section, double walls are formed locally in the area where the U-shaped legs overlap, thereby improving the mechanical protection and electrical insulation of the conductor connection terminal.

[0017] It is advantageous if the second housing part has a housing end wall for covering the end face of the housing. In particular, the second housing part can have two housing end walls for covering the end face of the housing on two opposite end faces of the housing. One housing end wall can extend substantially transversely to a direction of insertion of an electrical conductor into the conductor connection terminal. One housing end wall can extend substantially transversely to a long side of the housing. One end face of the housing can run substantially parallel to an end face of the contact insert inserted into the housing. One end face of the housing can be a housing side through which a conductor inserted into the conductor connection terminal enters the housing. One end face of the housing can have a smaller housing surface than a long side of the housing.A housing end wall can be a housing wall of the housing or housing part. A housing end wall improves the covering function of the second housing part in the end region 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 insertion opening.

[0018] It is advantageous if the conductor connection terminal is a double terminal for two electrical conductors that can be inserted into the conductor connection terminal in a respective insertion direction. The respective insertion directions can, for example, be opposite to one another. This allows two conductors to be connected to the conductor connection terminal without requiring a great deal of additional installation space or design effort. For example, the contact insert can have two clamping springs arranged opposite one another and a common busbar for both spring-loaded terminal connections. The housing of the conductor connection terminal can, for example, have two end-mounted, opposite-side housing walls with conductor insertion openings. In further embodiments, it is also conceivable to connect more than two electrical conductors to the conductor connection terminal.

[0019] It is advantageous if a partition wall projects transversely from the frame wall and / or from the first housing wall. This can enable or improve the spatial separation of two or more conductor connection spaces for spring-loaded terminal connections. The second housing part can have a partition wall receptacle, which is designed, for example, as two spaced-apart, also wall-like material projections, between which the partition wall can be inserted. This increases the stability of the conductor connection terminal and simplifies assembly, since the partition wall receptacle can serve as a guide and orientation for the positioning of the first and second housing parts relative to one another. The partition wall and the partition wall receptacle can also be detachably connected to one another by means of a snap-in connection in order to improve the connection between the first and second housing parts.The insulation of the conductor connection compartments from one another is further improved by a wall-like partition.

[0020] One or more frame walls can have a frame recess, which can, for example, run parallel to a housing wall recess of the second housing part and together with it form a grip recess. The grip recess can facilitate gripping of the conductor terminal or, for example, also visualize the top or bottom of the conductor terminal.

[0021] It is advantageous if the frame wall has a support block that projects transversely from the frame wall. This can, for example, support a contact insert at the end or limit its axial mobility. The support block can more precisely define the receiving space for the contact insert. The support block can increase the stability of the first housing part. The frame wall can also have two or more support blocks that project transversely from the frame wall. The support block(s) can, together with one or more frame walls and the first housing wall of the first housing part, form a receiving structure or an inner housing for the defined reception of the contact insert.

[0022] The support block may have a conductor entry channel area. This improves the guidance of an inserted electrical conductor and simplifies the operation of the conductor terminal.

[0023] 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 easier because, for example, the contact insert can be inserted into the first housing part in more than one orientation. The axis of symmetry can, for example, coincide with a central axis of the contact insert or the housing, which runs through the spatial center of the body of the contact insert or the housing.

[0024] It is advantageous if the first housing part and the second housing part are locked, caulked, 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 connection terminal.

[0025] 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, wherein in the assembled state of the housing the first conductor entry channel section and the second conductor entry channel section together form a conductor entry channel for inserting an electrical conductor. The joint formation of the conductor entry channel increases its stability and expansion. Furthermore, the assembly of the conductor connection terminal is simplified and intuitive because, when the first and second housing parts are connected to one another, the conductor entry channel sections are to be arranged adjacent to one another. Furthermore, the manufacture of the first and second housing parts is simplified if only one conductor entry channel section is provided on each of them, thus, for example, requiring fewer undercuts.The first conductor entry channel section can be assigned to the base housing of the conductor terminal, and the second conductor entry channel section can be assigned to the cover housing of the conductor terminal. 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 conductor terminal.

[0026] It is advantageous if the first conductor entry channel section and / or the second conductor entry channel section are configured to be substantially or predominantly closed circumferentially. In particular, the first conductor entry channel section and / or the second conductor entry channel section can be configured to be circumferentially closed by more than 180°, in particular more than 270°. The first conductor entry channel section and / or the second conductor entry channel section can thus have a substantially closed cross-section. This more precisely defines the conductor entry channel and increases the stability of the conductor connection terminal in the conductor entry region. Safe and intuitive insertion of an electrical conductor into the conductor entry channel is possible.If the first conductor insertion channel section and the second conductor insertion channel section are designed to be substantially closed on the circumference, the area of ​​the first housing part and the second housing part adjacent to the conductor insertion channel can be at least partially covered, so that the at least partial cover results in increased stability and better insulation of the contact insert by the housing.

[0027] The first conductor insertion channel section can be arranged behind the second conductor insertion channel section in the conductor insertion direction. When the electrical conductor is inserted, it thus first passes through the second conductor insertion channel section and then through the first conductor insertion channel section.

[0028] It is advantageous if the housing has a conductor insertion opening for inserting an electrical conductor, which is formed on the second conductor channel section. The conductor insertion opening defines the insertion region of the electrical conductor into the housing and is therefore visible from the outside. The conductor insertion opening can, for example, form a region of the largest cross-section of the conductor insertion channel in the case of a conductor insertion channel that tapers in the conductor insertion direction. A housing wall, in particular a housing end wall of the second housing part or cover housing, can enclose or frame the conductor insertion opening. The conductor insertion opening can be designed as an opening in a housing wall or housing end wall of the second housing part or cover housing.

[0029] The problem is also solved by using a conductor connection 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 the simple design, simplified assembly, and high insulation capacity of the conductor connection terminal, it is particularly suitable for use in repair work.

[0030] The object is also achieved with a method for assembling a conductor connection terminal with a contact insert that has a busbar and a clamping spring, and with a housing having a first housing part and a second housing part that at least partially encloses the contact insert, in which the contact insert is inserted into the first housing part and then the second housing part, which has a plurality of housing walls, is arranged on the first housing part and connected to it. This provides a method that enables particularly simple, quick and intuitive assembly of a conductor connection terminal. By covering the contact insert by means of a plurality of housing walls of the second housing part, compliance with the necessary air and creepage distances for the operational reliability of the conductor connection terminal is ensured. The first housing part can form a base housing and the second housing part can form 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 method step by assembling at least one busbar and at least one clamping spring. The contact insert can, in particular, be preassembled.

[0031] It is advantageous if the insertion direction of the contact insert into the first housing part lies transversely to the longitudinal direction of the contact insert. The longitudinal direction of the contact insert can run essentially parallel to a conductor insertion direction. During assembly, the contact insert is not inserted or pushed into a housing with one end face first in a conductor insertion direction or opposite thereto, but rather is moved transversely to this direction towards the first housing part and placed, 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 takes place in a placement direction that in particular corresponds to the insertion direction of the contact insert into the first housing part or runs parallel to this.

[0032] It is advantageous if the method is used to assemble a conductor connection terminal according to one of the features described above.

[0033] In general, in the context of this application, the words "a / an" are not to be understood as numerals, unless expressly defined otherwise, but as indefinite articles with the literal meaning "at least one / an." All angles refer to a circle of 360°.

[0034] The invention is explained in more detail below using an exemplary embodiment with the accompanying drawings. They show schematically: 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 connection terminal with inserted contact insert and assembled housing; Fig. 7- a perspective sectional view of the conductor connection terminal with inserted contact insert and assembled housing; Fig. 8- a perspective rear view of the conductor connection terminal with assembled housing; Fig. 9- a sectional side view of the conductor connection terminal with inserted contact insert and assembled housing; Fig. 10- a perspective sectional side view of the conductor connection terminal with inserted contact insert and assembled housing; Fig.Fig. 11- a contact insert for a conductor terminal; Fig. 12- a method for assembling a conductor terminal.

[0035] Figure 1 shows a front view of a first housing part 5A for a device shown for example in the Figures 6 to 10 shown, designed as a double terminal conductor connection terminal 1. The first housing part 5A can be connected to a, for example, Figures 3 to 5 shown second housing part 5B to form a housing 5 of the conductor connection terminal 1. The housing 5 of the conductor connection terminal 1 is constructed in two parts in the illustrated embodiments from the first housing part 5A and the second housing part 5B. It is fundamentally conceivable to also 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 a Figures 6 , 7 and 11to at least partially enclose the contact insert 2 shown with a busbar 3 and one or more clamping springs 4 in order to protect the contact insert 2 from ambient conditions and to effect electrical insulation of the contact insert 2 from the environment.

[0036] The first housing part 5A has a first housing wall GW1 with a receiving structure 6 for receiving the contact insert 2. In the exemplary embodiments shown, the receiving structure 6 is formed by several structural elements, such as frame walls 7 (explained below), a partition wall 10, spring supports, and support blocks 12. However, it is also conceivable to provide more or fewer structural elements to form the receiving structure 6.

[0037] Two frame walls 7 protrude substantially vertically from the first housing wall GW 1 and, together with the first housing wall GW 1, delimit a receiving space 8 for the contact insert 2. The frame walls 7 extend along the long sides of the contact insert 2 to be inserted. In the exemplary embodiment shown, a frame wall 7 extends along a line facing the busbar 3 of the contact insert 2 and in Figure 11 shown underside Ku of the contact insert 2 and along a side facing away from the busbar of the contact insert 2, in Figure 11 shown top side Ko of the contact insert 2. One of the two frame walls 7 shown has a frame recess 16A, which is, for example, parallel to a housing wall recess 16B ( Fig. 3) of the second housing part 5B and together with it forms a gripping recess. The gripping recess can facilitate gripping of the conductor connection terminal 1 and, in the illustrated embodiments, visualizes an upper side of the conductor connection terminal 1 facing away from the busbar 3 of the contact insert 2.

[0038] A partition wall 10 protrudes essentially perpendicularly from the first housing wall GW 1 and from one of the frame walls 7. This partition wall serves, among other things, to spatially separate and electrically insulate two adjacent connection compartments for electrical conductors. In the exemplary embodiment, the partition wall 10 defines a central region of the first housing part, from which a spring-loaded terminal connection for an electrical conductor can be provided on the left and right. For this purpose, an electrical conductor can be inserted into the conductor connection terminal 1 in an insertion direction R EF.

[0039] Support blocks 12 protrude from the frame walls 7, which further delimit the receiving space 8 for the contact insert 2 and reduce or prevent a translational mobility of the contact insert 2 in the same or opposite direction to the insertion direction R EF.

[0040] Furthermore, a first conductor insertion channel section 13A is formed on the first housing part 5A for each side of the double terminal, which, in the assembled state of the housing 5, together with a Figure 3 shown second conductor insertion channel section 13B of the second housing part 5B forms a conductor insertion channel 13.

[0041] In Figure 21, the first housing part 5A is shown in a rear view. For example, it can be seen how one of the frame walls 7 protrudes substantially perpendicularly from the first housing wall GW 1. Here, the frame wall 7 is offset slightly inward, i.e., it does not have a surface flush with an end edge of the first housing wall GW 1. The recess 17 formed between the frame wall 7 and the end 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.

[0042] Figure 3shows a front view of a second housing part 5B for the conductor connection terminal 1. The second housing part 5B has a plurality of housing walls, specifically in the exemplary embodiment shown 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 connection terminal 1 and, supplemented by the first housing wall GW 1 of the first housing part 5A, form the housing 5 of the conductor connection 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 onto the first housing part 5A after a contact insert 2 has been installed in the first housing part 5A.The housing walls GW 1 , GW 2 , GW 3 , GW 4 can be assigned to the long sides of the conductor connection terminal 1 or of the housing 5 or of the contact insert 2, while the housing end walls GWs can be assigned to the end faces of the conductor connection terminal 1 or of the housing 5 or of the contact insert 2. The housing end walls GWs of the second housing part 5B each have an opening which forms a conductor insertion opening 14 and a second conductor insertion channel section 13B. An electrical conductor, in the exemplary embodiment shown an electrical conductor from opposite end faces of the second housing part 5B, can be inserted into the housing 5 in a conductor insertion direction R EF.

[0043] The second housing part 5B has a partition wall receptacle 11 in the form of two spaced, wall-like material projections, between which the partition wall 10 of the first housing part 5A can be inserted. The second housing part 5B has a housing wall recess 16B, which, in the assembled state of the housing 5, covers a frame recess 16A of the first housing part 5A and, together with the frame recess, forms a grip recess.

[0044] The Figures 4 and 5 show the second housing part 5B for further illustration in a further front view and a bottom view.

[0045] Figure 6shows the conductor connection terminal 1 in an assembled state, i.e. with an inserted contact insert 2 and the housing 5 enclosing the contact insert 2 and formed from the first housing part 5A and the second housing part 5B. The contact insert 2 can be seen with a busbar 3 and two clamping springs 4 for two spring-loaded clamp connections of two electrical conductors (not shown) that can be inserted into the conductor connection 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, so that in each case a double wall is present that increases the insulation and stability of the conductor connection terminal 1.It can also be seen that the first conductor insertion channel section 13A of the first housing part 5A and the second conductor insertion channel section 13B of the second housing part 5B together form a conductor insertion channel 13 for inserting an electrical conductor, starting with the conductor insertion opening 14 of the second housing part 5B. The support blocks 12 additionally have a conductor insertion channel region 18 for continuing the conductor insertion channel 13. Furthermore, it is clear how the receiving structure 6 of the conductor connection terminal 1, with several structural elements such as spring supports, the partition wall receptacle 11, the frame walls 7, and the support blocks 12, define a delimited receiving space for the contact insert 2, so that the contact insert is securely held in the housing 5 and assembly is facilitated.Furthermore, it can be seen that the partition 10 extends 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. A symmetrical structure of the conductor connection terminal 1 is also clearly visible, with a symmetry axis (not shown) running perpendicular to the insertion direction R EF through the partition 10.

[0046] The conductor connection terminal 1 has a simplified design and enables easier assembly of the conductor connection terminal 1. The receiving structure 6 of the first housing wall GW 1 of the first housing part 5A is easily accessible and enables quick and secure assembly of the contact insert 2 on the first housing part 5A. The second housing part 5B can be safely and quickly arranged on the first housing part 5A and connected to it. By covering the contact insert 2 by means of several housing walls GW 2 , GW 3 , GW 4 , GW S of the second housing part 5B, compliance with the required air and creepage distances for the operational reliability of the conductor connection terminal 1 is ensured.

[0047] Figure 7 shows the representation of the conductor connection terminal 1 from Figure 6for further illustration in a perspective view. Additionally, the longitudinal extension direction R LE of the contact insert 2 is indicated by a double arrow. When assembling the conductor connection terminal 1, the contact insert 2 is inserted into the first housing part 5A transversely to this longitudinal extension direction R LE in an insertion direction R ES.

[0048] Figure 8shows a perspective rear view of the conductor connection terminal 1 with the assembled housing 5. It can be seen that the housing parts 5A, 5B are assembled along a connecting line 15. At the 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 flush with one another. The situation is similar on the opposite side at the transition from the first housing wall GW 1 to the third housing wall GW 3 . The first housing part 5A and the second housing part 5B can, for example, also be latched, caulked and / or welded to one another in the assembled state of the housing 5.

[0049] Figure 9shows a sectional side view of the conductor connection terminal 1 with inserted contact insert 2 and housing 5 assembled from the housing parts 5A, 5B. In this view it can be seen that the first housing part 5A and the second housing part 5B in the embodiment shown each have a U-shaped cross-section, 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.

[0050] Figure 10 shows the sectioned view of the conductor connection terminal 1 from Figure 9 for additional illustration in a perspective view.
