Description

[Technical Field]

[0001] The present invention relates to a conductor connection terminal comprising an insulator housing and a contact insert for connecting an electrical conductor.The present invention also relates to a method for assembling a conductor connection terminal. The present invention generally relates to the field of electrical connection technology. Conductor connection terminals are used, inter alia, for clamping conductors and for establishing a conductive connection between the conductors and the connection contacts of the conductor connection terminals by means of contact inserts. [Background technology]

[0002] For economic reasons, inexpensive production of conductor connection terminals is desirable. Therefore, for example, an efficient manufacturing process suitable for mass production is a goal. At the same time, the conductor connection terminals provided must be highly reliable, have a long service life, and be easy to handle, i.e., component quality must not be compromised by economical manufacturing processes. For example, it is desirable for the contact inserts of the conductor connection terminal to be precisely aligned within the insulator housing so that the connection process can be carried out easily and reliably. However, precise positioning of the contact inserts within the insulator housing is associated with increased manufacturing effort, as tight tolerances can sometimes make installation of the contact inserts within the insulator housing difficult. Balancing these conflicting requirements presents a technical challenge in the development of conductor connection terminals.

[0003] DE 10 2004 014 353 B4 discloses a plug or socket for a plug-in connector with a contact partner having abutment elements in the form of spring tabs which protrude beyond the outer part of the contact partner and which, in the plugged-in state, exert a contacting and holding force on the electric lines in the receiving support.

[0004] [Patent Document 1] DE102004014353B4 Summary of the Invention [Problem to be solved by the invention]

[0005] In light of this, the object of the present invention is to provide a conductor connection terminal with an improved insulator housing and contact insert that can be produced economically and efficiently and that allows for a connection process that can be carried out easily and reliably. [Means for solving the problem]

[0006] This problem is solved by a conductor connection terminal according to claim 1 and by a method for assembling a conductor connection terminal according to claim 18. Advantageous embodiments can be inferred from the dependent claims, the description and the drawings.

[0007] A conductor connection terminal is proposed, which comprises an insulator housing and a contact insert for connecting an electrical conductor, the insulator housing comprising a first housing part with a plug profile and a second housing part with a mating plug profile, the mating plug profile being adapted for plug-in connection with the plug profile of the first housing part. The first housing part has a receiving chamber with two opposing side walls for receiving the contact insert. The distance between the opposing side walls defines a chamber width of the receiving chamber, and the mating plug profile of the second housing part is adapted to reduce the chamber width of the receiving chamber in at least a section by at least partial deformation and / or movement of at least one side wall of the receiving chamber of the first housing part during establishment of the plug-in connection between the plug profile of the first housing part and the mating plug profile of the second housing part.

[0008] In other words, a conductor connection terminal is proposed that includes a pluggable insulator housing, the receiving chamber of which can be reduced in width by the component structure of the insulator housing during plugging, specifically so that the contact insert disposed in the receiving chamber is aligned and fixed within the narrowed receiving chamber. This allows the contact insert to be simply positioned in one part of the insulator housing during manufacturing, particularly with play, and only when another part of the insulator housing is fixed in the final assembly step can the contact insert be fixed in the receiving chamber, advantageously reducing or completely eliminating any play that may exist within the receiving chamber. Additionally, the narrowing of the chamber can enable self-centering of the contact insert within the receiving chamber, thereby achieving precise positioning of the contact insert. For precise positioning, for example, the conductor connection region of the contact insert can be aligned with the conductor insertion path of the conductor connection terminal. Advantageously, with the proposed conductor connection terminal, simple manufacturing can be combined with reliable and easy handling of the conductor connection terminal. According to some embodiments, the narrowing of the chamber can be reversed, for example by an elastic component structure, so that when the housing parts are separated from each other, the original chamber width of the receiving chamber can be restored.

[0009] The insulator housing may be made of an electrically insulating material, such as plastic. The insulator housing may protect the contact inserts from environmental influences and contact. The insulator housing has first and second housing parts and is therefore multi-part. The first and second housing parts are connectable to one another, particularly by a removable plug connection, and are adapted to securely and protectively accommodate the contact inserts inside the insulator housing when plugged together. The plug profile of the first housing part and the mating plug profile of the second housing part are configured to mate with one another and thus can be connected to one another. For example, the plug profile can form the negative profile of the mating plug profile, or vice versa. Optionally, the plug connection may be configured as a snap connection, in which case the plug profile and the mating plug profile may have locking edges and locking elements that engage with the locking edges to provide a plug connection that prevents unintentional disconnection.

[0010] The contact insert can be a one-part contact element or a multi-part contact assembly, depending on the embodiment, which includes conductive contact pieces adapted to establish an electrical connection between an electrical conductor connectable with the contact insert and a connection contact of the conductor connection terminal. According to one embodiment, which will be explained in more detail below, the contact insert can have a spring clamp connection, whereby the electrical conductor can be supported and clamped to the conductive contact piece by means of a spring force. For this purpose, the contact insert can include, for example, contact pieces on which clamping springs are arranged, and the clamping springs can be attached, for example, to the contact pieces.

[0011] The receiving chamber can be a hollow space within the insulator housing, adapted to receive the contact insert, e.g., having a suitable shape and appropriate dimensions for this purpose. The receiving chamber can be largely closed by being surrounded on multiple sides by the housing structure of the insulator housing; for example, a conductor insertion passage for guiding the conductor to the contact insert can lead to the receiving chamber. In this regard, the insulator housing has two side walls defining the receiving chamber, which face each other and whose distance determines the chamber width of the receiving chamber. When the conductor connection terminal is assembled, the contact insert can be disposed between these two opposing side walls. In this case, the width of the contact insert can substantially correspond, particularly at most, to the chamber width of the receiving chamber or can be smaller than the chamber width, so that, if desired, lateral play of the contact insert between the opposing side walls is possible during the assembly process. When the first housing part is then mated with the second housing part by plugging, the plugging profile of the first housing part and the mating plugging profile of the second housing part cooperate to at least partially deform and / or move at least one side wall of the receiving chamber during the plugging process, thereby narrowing the receiving chamber. At least partial deformation and / or movement can mean, for example, a local or at least partial section deformation and / or movement of the side wall; therefore, the entire side wall does not necessarily need to be affected by the deformation and / or movement. However, according to some embodiments, deformation and / or movement can also occur across the entire side wall. Here, deformation and / or movement can refer, for example, to elastic deformation and / or movement, so that the resulting deformation or warping of the side wall is essentially reversible. For this purpose, the side wall of the receiving chamber can have limited elasticity, e.g., limited bending stiffness, in at least a limited section, for example, due to an appropriate material or appropriate molding.

[0012] According to one embodiment, the plug profile of the first housing part can be configured as a socket-shaped plug profile, and the counter plug profile of the second housing part can be configured as a pin-shaped counter plug profile. This allows for easy provision of plug profiles and counter plug profiles that fit together and can be easily connected to each other. As a pin-shaped counter plug profile, this counter plug profile can be insertable into the socket-shaped plug profile. The socket-shaped plug profile can be a component structure with an elongated passage. The pin-shaped counter plug profile can be a component structure with an elongated protrusion. To form a plug connection, the pin-shaped counter plug profile can enter at least a portion of the socket-shaped plug profile. The counter plug profile can be fully insertable or inserted into the plug profile, but this is not necessarily required.

[0013] According to one embodiment, the plug profile of the first housing part can be configured as a plug channel, at least one of whose walls forms a side wall of the receiving chamber of the first housing part. This allows the plug profile to be compactly integrated into the housing structure of the first housing part. Furthermore, when establishing a plug connection between the plug channel and the counter plug profile, the counter plug profile is guided along the side wall in the plug channel, so that a direct movement and / or deformation of the side wall of the receiving chamber can be achieved.

[0014] According to one embodiment, the mating plug profile of the second housing part can have an expansion profile, which allows the movement and / or deformation of the side walls of the receiving chambers caused by the counter plug profile to be reliably induced or enhanced. The expansion profile can be, for example, a wing-like or radial protrusion on the mating plug profile. The expansion profile can, for example, protrude radially (i.e., laterally) from an elongated, particularly pin-shaped, mating plug profile. According to an advantageous variant, the mating plug profile can have multiple expansion profiles protruding from the mating plug profile, thereby allowing the movement and / or deformation of each one of the side walls of two adjacent receiving chambers, for example, in an insulating housing with multiple receiving chambers and between which the counter plug profile is inserted.

[0015] According to one embodiment, the mating plug profile can have an insertion slope for inserting the mating plug profile into the plug profile. This allows the mating plug profile to be inserted more easily into the plug profile and can facilitate gradual deformation and / or movement of the side wall of the receiving chamber. For this purpose, the mating plug profile can preferably be configured as a pin-shaped mating plug profile, and the plug profile can preferably be configured as a socket-shaped plug profile. A mating plug profile with an insertion slope can be advantageous, in particular, when the mating plug profile has an expansion profile or when the plug profile of the first housing part and the mating plug profile of the second housing part are configured to have an interference fit with each other, according to an embodiment described in more detail below. The insertion slope can be arranged on the mating plug profile so that it faces the plug profile during insertion of the mating plug profile into the plug profile and enters the plug profile as a first partial region of the mating plug profile.

[0016] According to one embodiment, the counter plug profile can have guide bars for guiding the counter plug profile along the plug profile. This can simplify and assist the establishment of the plug connection between the plug profile and the counter plug profile. For this purpose, the counter plug profile can preferably be formed as a pin-shaped counter plug profile, and the plug profile can preferably be formed as a socket-shaped plug profile. The guide bars can be adapted to be guided along the outside of the plug profile, for example, to align the counter plug profile with the plug profile and to facilitate the connection. According to one variant, the counter plug profile can have multiple guide bars that clamp the plug profile between them and can provide a centered positioning of the counter plug profile relative to the plug profile. If the insertion contour of the first housing part is formed as an insertion channel, at least one channel wall of which forms a side wall of the receiving chamber of the first housing part, the guide bar is also guided along the side wall outside the insertion channel and at least partially limits the warping and / or deformation of the side wall, thereby achieving stabilization of the moved and / or deformed side wall.

[0017] According to one embodiment, the plug profile of the first housing part and the mating plug profile of the second housing part may be configured to have an interference fit with respect to each other. For example, the mating plug profile may have a larger width or a larger diameter than the plug profile when it is adapted for insertion into the plug profile. For example, a pin-shaped mating plug profile may have a larger diameter perpendicular to the plug direction of the mating plug profile than the assigned socket-shaped plug profile. Due to the interference fit, the mating plug profile may be configured to expand (i.e., widen) the plug profile, which may cause deformation and / or movement of the side walls of the receiving chamber. This may provide a structurally simple embodiment for reducing the chamber width of the receiving chamber by the plug profile and the mating plug profile.

[0018] According to one embodiment, the insulator housing may have at least two parallel-extending receiving chambers for respectively receiving contact inserts for connecting conductors. This allows a plurality of conductors to be connected to the conductor connection terminal. The conductor connection terminal may therefore have a plurality of connection portions, each of which is provided by a contact insert. Each contact insert may be arranged in a respective receiving chamber. The receiving chambers may be aligned with one another, and the contact inserts may be aligned, for example, parallel to one another within the receiving chambers.

[0019] According to one variant, at least one side wall of the receiving chamber may form an isolation structure for the adjacent receiving chamber, thereby achieving a compact arrangement and structural isolation of the receiving chambers with sufficient clearance and creepage distances. For example, two adjacent receiving chambers may be separated from each other by a common side wall or separate side walls in the form of a double wall.

[0020] According to one variant, the plug profile of the first housing part can be configured as a plug channel, two opposing walls of which can respectively form the side walls of two adjacent receiving chambers, so that the mating plug profile inserted into the plug channel can achieve a simultaneous movement and / or deformation of the side walls forming the plug channel in the two adjacent receiving chambers, thereby effectively narrowing the chambers simultaneously in both receiving chambers.

[0021] According to one variant, the chamber width of the receiving chamber can be smaller than the contact spacing (i.e., the distance between the contacts) of the insulator housing. In particular, the chamber width reduced by the deformation and / or movement of at least one side wall of the receiving chamber can be smaller than the contact spacing of the insulator housing. The contact spacing can be, for example, the distance between the longitudinal central axes of adjacent conductor insertion openings of the insulator housing, through which conductors to be connected can be guided into the adjacent receiving chambers.

[0022] According to one embodiment, when the first and second housing parts are not connected to each other, the contact insert may have play in the receiving chamber, and when the first and second housing parts are connected to each other, the contact insert may have reduced or no play. The play may be, in particular, play in the direction of the chamber width, i.e., the gap between the contact insert and the opposing side walls of the receiving chamber that define the chamber width. Therefore, by reducing the chamber width of the receiving chamber, the play existing in the contact insert in the receiving chamber can be reduced or completely eliminated. This allows the contact insert to be easily installed in the receiving chamber initially and to be aligned and fixed relative to each other during the connection of the housing parts, thereby enabling reliable and easy connection of conductors in the conductor connection terminal. If the conductor connection terminal is designed as a plug connector, the mating connector can be inserted and connected more easily.

[0023] According to one embodiment, the contact insert can have a spring clamp connection. A spring clamp connection is a conductor connection with a clamp spring that can clamp the conductor to the conductive contact piece of the contact insert with spring force. The spring clamp connection allows the conductor to be connected easily and with little force, and to be reliably contacted. It is advantageous for the clamp spring to form a movable part of the contact insert if the contact insert can be inserted with play into the receiving chamber of the conductor connection terminal. In addition, it is preferable that the contact insert can be accurately positioned, for example, by reducing the chamber width of the receiving chamber, in order to align it with the conductor insertion path of the conductor connection terminal, and can be fixed in the aligned position.

[0024] According to one variant, the conductor connection terminal can have an actuation element for actuating the spring clamp connection. The actuation element can be, for example, an actuation lever or an actuation push button, which can move the clamping legs of the clamping spring from a clamping position to an open position in order to facilitate the insertion of an electrical conductor into the conductor connection terminal in the region of the clamping position or to release a connected conductor. If the contact insert of the conductor connection terminal is accurately positioned and fixed in its receiving chamber, actuation of the spring clamp connection can be carried out reliably and with little force.

[0025] According to one embodiment, the first and second housing parts can form a common, elongated (i.e., elongated) receiving chamber for the contact insert, with the receiving chamber of the first housing part having a first chamber section and the second housing part having a second chamber section. The second chamber section of the second housing part forms an extension of the receiving chamber of the first housing part when the first and second housing parts are mated together. This can further simplify the assembly of the conductor connection terminal, since the contact insert only needs to be placed in a partial region of the receiving chamber, and the receiving chamber is only fully formed and closed when the housing parts are connected. For example, the opposing side walls defining the chamber width can be formed partly by the first housing part and partly by the second housing part and assembled during the establishment of the plug-in connection between the housing parts.

[0026] According to one embodiment, the first housing part can have at least one plug connection for establishing an electrical connection to the contact insert. This allows the conductor connection terminal to be formed as a plug connector. The plug connector allows for simple and fast establishment of a detachable electrical connection between the plug connector and a mating electrical connector. For this purpose, the first housing part can have a plug connection that is aligned for coupling with a corresponding mating plug connection of the mating connector. The plug connection can have, for example, a socket-like or pin-like plug contact element. The plug connection can form the aforementioned connection contact of the conductor connection terminal. According to an alternative embodiment, or additionally, it is conceivable that the second housing part can have at least one plug connection for establishing an electrical connection to the contact insert.

[0027] According to one embodiment, the second housing part can have at least one conductor insertion opening for guiding the conductor into the contact insert, which allows the conductor to be reliably guided through the insulator housing into the contact insert. A conductor insertion passage can be adjacent to the conductor insertion opening, which opens into the receiving chamber and allows the conductor to be accurately guided into the contact insert. According to an alternative embodiment, or additionally, it is conceivable that the first housing part has at least one conductor insertion opening for guiding the conductor into the contact insert.

[0028] The present invention further provides a method for assembling a conductor connection terminal with an insulator housing and a contact insert, comprising the steps of: - providing a first housing part of an insulator housing, the first housing part having a plug contour and a receiving chamber with two opposing side walls for receiving the contact insert, the spacing between the opposing side walls defining a chamber width of the receiving chamber; - providing a second housing part of the insulator housing, the second housing part having a mating plug-in profile adapted for plug-in connection with the plug-in profile of the first housing part, - providing a contact insert; - inserting a contact insert into a receiving chamber of the first housing part; and - establishing a plug-in connection between the first housing part and the second housing part, the mating plug-in contour of the second housing part being adapted to reduce the chamber width of the accommodating chamber in at least a section by at least partial deformation and / or movement of at least one side wall of the accommodating chamber of the first housing part during the establishment of the plug-in connection, The present invention relates to a method having the following structure:

[0029] This allows the contact insert to be placed in the first housing part simply in one assembly step, in particular with play, and in a further assembly step, the position of the contact insert in the receiving chamber can be fixed while the second housing part is fastened, advantageously reducing or completely eliminating any play of the contact insert that may be present in the receiving chamber. The conductor connection terminal may be formed in particular according to one of the above-mentioned features.

[0030] Generally speaking, in the context of this application, the word "ein / eine" is to be understood as an indefinite article with the meaning "at least one" and not as a numeral, unless expressly defined otherwise.

[0031] Although the present invention allows various embodiments, it will be described in more detail below based on one exemplary embodiment with reference to the accompanying drawings. [Brief explanation of the drawings]

[Figure 3] 1 is a schematic exploded view of the first and second housing portions prior to mating; FIG. [Figure 4] 2 is a schematic front view of the first housing portion of the insulator housing shown in FIG. 1 in isolation, with the side wall in a deformed state; [Figure 5] 2 is a schematic front view of the second housing portion of the insulator housing shown in FIG. 1 in isolation; [Figure 6] 4 is a simplified flowchart of a method for assembling a conductor connection terminal. DETAILED DESCRIPTION OF THE INVENTION

[0033] 1 and 2 show an insulator housing 1 of a conductor connection terminal, which comprises a first housing part 2 and a second housing part 4. The first housing part 2, according to the illustrated exemplary embodiment, has a socket-shaped plug profile 3. The second housing part 4, according to the illustrated exemplary embodiment, has a pin-shaped mating plug profile 5. The mating plug profile 5 is adapted for a plug-in connection with the plug profile 3 of the first housing part 2. FIGS. 1 and 2 show the first housing part 2 and the second housing part 4 in a mated state, where a plug-in connection between the plug profile 3 and the mating plug profile 5 is established. The first housing part 2 has a number of receiving chambers 6, each with two opposing side walls 7, for receiving a contact insert (not shown in more detail). The spacing between the opposing side walls 7 defines a chamber width W of each receiving chamber 6.

[0034] The mating plug-in contour 5 of the second housing part 4 is adapted to at least partially deform and / or move (in other words, displace) at least one side wall 7 of the receiving chamber 6 during the establishment of the plug-in connection between the plug-in contour 3 of the first housing part 2 and the mating plug-in contour 5 of the second housing part 4, thereby reducing the chamber width W of the receiving chamber 6 in at least a section. This allows the receiving chamber 6 to be narrowed so that the contact insert therein is aligned and fixed in place. The contact insert can therefore be easily placed in the first housing part 2 during production of the conductor connection terminal, in particular with play (in other words, a gap), and fixed by the narrowing of the receiving chamber 6 when the second housing part 4 is fixed to the first housing part 2. The side wall 7 may be elastically deformable and / or movable, for example by a suitable material or suitable molding, for example by a thin and elongated structural design, so that the narrowing of the chamber can return to its original state when the housing parts 2, 4 are separated from each other, and the original chamber width W can be restored when the housing parts 2, 4 are separated.

[0035] 1 and 2, the plug-in profile 3 of the first housing part 2 can be formed as a plug-in passage (in other words, a plug-in channel) 8, with at least one passage wall 9 of the plug-in passage 8 forming a side wall 7 of the receiving chamber 6 of the first housing part 2. This allows the plug-in profile 3 to be compactly integrated into the housing structure of the first housing part 2, and when the counter plug-in profile 5 is guided in the plug-in passage 8 along the side wall 7, a direct deformation and / or movement of the side wall 7 can be caused.

[0036] According to the exemplary embodiment shown in FIGS. 1 and 2, the insulator housing 1 has a plurality of, in the illustrated example, four parallel-extending receiving chambers 6 for receiving one contact insert each. This allows a number of conductors to be connected to the conductor connection terminal. As can be further seen from FIGS. 1 and 2, the side walls 7 of the receiving chambers 6 may each form a separation structure for adjacent receiving chambers 6, thereby providing a compact arrangement. The plug-in contours 3 formed as plug-in passages 8 have two opposing passage walls 9, which respectively form the side walls 7 of two adjacent receiving chambers 6. It is further shown that the chamber width W of the receiving chambers 6 is smaller than the contact spacing R of the insulator housing 1, which can be represented by the distance between the longitudinal central axes of adjacent conductor insertion openings 14.

[0037] As can be seen in Figures 1 and 2, the first housing part 2 and the second housing part 4 can together form a receiving chamber 6, with the first chamber section 6a being defined by the first housing part 2 and the second chamber section 6b being defined by the second housing part 4, respectively. This can further simplify the assembly of the conductor connection terminal. Furthermore, it can be seen that the second housing part 4 has a plug connection 13 for establishing an electrical connection to the contact insert, so that the conductor connection terminal is configured as a plug connector and can be coupled to a mating electrical connector. Additionally, Figures 1 and 2 show that the first housing part 2 has a conductor insertion opening 14 for guiding the conductor into the contact insert, allowing the conductor to be easily and reliably connected to the conductor connection terminal.

[0038] 3 shows an exploded view of the first and second housing parts 2, 4 before they are mated together. On its plug-in side facing away from the conductor insertion opening 14, the first housing part 2 has protruding side walls 7 which, together with the bottom and top walls, form a closed passageway. On its plug-in side facing away from the insertion opening 13, the second housing part 4 has a mating plug-in profile 5 with a guide bar 12 and an expansion profile 10. A gap is present between the guide bar 12 and the expansion profile 10, respectively, which is formed to accommodate the end region of the protruding side wall 7 on the plug-in side of the first housing part 2.

[0039] A bayonet passage 8 is formed between the pair of side walls 7 , the bayonet passage 8 being defined by passage walls 9 and configured to receive an expansion profile 10 . FIG. 4 shows the first housing part 2 of the insulator housing shown in FIG. 1 in isolation in a front view with the side wall 7 deformed.

[0040] It can be seen that each side wall 7 is deformed toward the first chamber section 6a of the adjacent receiving chamber 6, thereby reducing the width of the receiving chamber 6. An insertion passage 8 is formed between a pair of adjacent side walls 7, and this insertion passage 8 is configured to receive an expansion profile 10. By inserting the expansion profile 10, which has an insertion slope (i.e., a sloping portion) 11 and is wider than the insertion passage 8, the side wall 7 is pushed laterally outward from the insertion passage 8 and deformed.

[0041] FIG. 5 additionally shows the second housing part 4 alone in a front view. It can be seen from FIG. 5 that the mating plug profile 5 of the second housing part 4 has an expansion profile 10, which allows the movement and / or deformation of the side wall 7 caused by the mating plug profile 5 to be reliably induced or amplified. According to the illustrated exemplary embodiment, the expansion profile 10 is configured as a wing-like protrusion protruding from the pin-shaped mating plug profile 5 and is adapted to at least partially move and / or deform the side walls 7 of two adjacent receiving chambers 6. The expansion profile 10 can have a cross-sectional width greater than the plug passages 8, among other things. Thus, the expansion profile 10 can provide an interference fit between the plug profile 3 and the mating plug profile 5; in this regard, in an alternative embodiment, the pin-shaped mating plug profile 5 itself can have a cross-sectional width greater than the plug passages 8, without the expansion profile 10.

[0042] It can further be seen that the counter plug profile 5 has an insertion slope 11, which facilitates the insertion of the counter plug profile 5 into the plug profile 3 and allows for a gradual deformation and / or movement of the side wall 7. In other words, in cooperation with the expansion profile 10, a gradual expansion of the plug channel 8 can be achieved, which gradual expansion achieves a gradual narrowing of the chamber and thus a gradual fixation of the contact insert.

[0043] 5 further shows that the counter plug profile 5 each has two guide bars 12. The guide bars 12 are adapted to slide along the surface of the plug profile 3 and to facilitate the establishment of a plug connection between the plug profile 3 and the counter plug profile 5. In addition, the guide bars 12 can clampingly receive the plug profile 3 therebetween and can provide a centered alignment of the counter plug profile 5 relative to the plug profile 3.

[0044] 6 shows a schematic, highly simplified block diagram of a method 100 for assembling an insulator housing 1 and a conductor connection terminal with a contact insert. In a first step 110, a first housing part 2 of the insulator housing 1 is provided, which has a plug-in profile 3 and a receiving chamber 6 with two opposing side walls 7 for receiving the contact insert, the spacing between the opposing side walls 7 defining a chamber width W of the receiving chamber 6. In a further step 120, a second housing part 4 of the insulator housing 1 is provided, which has a mating plug-in profile 5 adapted for plug-in connection with the plug-in profile 3 of the first housing part 2. In a further step 130, a contact insert is provided. In a further step 140, the contact insert is inserted into the receiving chamber 6 of the first housing part 2. In a further step 150, a plug-in connection is established between the first housing part 2 and the second housing part 4, and during the establishment of the plug-in connection, with the aid of the mating plug-in contour 5 of the second housing part 4, the chamber width W of the receiving chamber 6 of the first housing part 2 is reduced in at least some sections due to at least partial deformation and / or movement of at least one side wall 7 of the receiving chamber 6 of the first housing part 2.

[0045] Advantageously, the described conductor connection terminal and the described assembly method allow simple manufacture to be combined with reliable and easy handling of the conductor connection terminal. [Explanation of symbols]
