Description

[0001] Terminal with latching closed insulating housing

[0002] The present invention relates to a terminal, in particular a connection or connecting terminal, with a plurality of spring-loaded terminal connections which are at least partially accommodated in a multi-part insulating housing.

[0003] Connection or connecting terminals for connecting multiple electrical conductors are generally known from the prior art. These are provided, for example, on an electrical load. The external wiring (external electrical conductors) can be connected to a first conductor terminal point and the internal wiring (internal electrical conductors) of the load can be connected to a second conductor terminal point, thus supplying the electrical load with power and / or transmitting (control) signals via the external wiring, the terminal, and further via the internal wiring.

[0004] Connection or connecting terminals are known in which several first conductor clamping points are arranged in a row and several second conductor clamping points are arranged in a row, with these rows then being arranged one above the other. All of the conductor entry channels leading to the respective conductor clamping points are provided in a housing body into which corresponding spring-loaded terminal connections can be inserted via an opening in the bottom. After insertion, the housing body is closed by a cover on the open side of the terminal. The cover is usually fastened to the housing body using ultrasonic welding in order to safely withstand any operating forces of the terminal. Such a terminal can be constructed relatively low. However, it is also conceivable for the cover to be snapped onto the housing body, for example using a form-fitting connection. However, such terminals are usually quite high.

[0005] It is therefore an object of the present invention to provide a clamp of the type mentioned above that can be provided simply, securely, and as compactly as possible. This object is achieved by the subject matter of the independent claim. The dependent claims develop the central idea of ​​the present invention in a particularly advantageous manner.

[0006] The invention relates to a terminal, in particular a connection or connecting terminal. This terminal has a plurality of first spring-loaded terminal connections, each with a first conductor clamping point for electrically connecting a conductor. Furthermore, the terminal also has a plurality of second spring-loaded terminal connections, each with a second conductor clamping point for electrically connecting a conductor. Furthermore, the terminal has an insulating housing that at least partially and preferably completely accommodates the (i.e., all) spring-loaded terminal connections. The insulating housing, in turn, has a first conductor insertion channel for each first conductor clamping point, extending in a first conductor insertion direction from the outside to the respective first conductor clamping point.Furthermore, the insulating housing also has a second conductor insertion channel for each second conductor terminal point, extending in a second conductor insertion direction from the outside to the respective second conductor terminal point. The insulating housing has an upper housing part, which has the first conductor insertion channels. Furthermore, the insulating housing also has a lower housing part, which has the second conductor insertion channels. The insulating housing also has pairs of locking partners distributed between the upper and lower housing parts in order to connect the upper and lower housing parts in a locking connection.

[0007] By each housing part, namely the upper housing part and the lower housing part, completely accommodating one of the groups of first conductor entry channels or second conductor entry channels, thus distributing these between the two housing parts, each of the housing parts can be provided in a functionally self-contained manner. This allows defined clearance and creepage distances to be reliably maintained even with a compact design. The two housing parts are thus provided in a very robust manner and can thus easily and stably have the appropriately distributed and corresponding locking partners of the locking partner pairs, thus forming a locking connection for the secure locking connection of the two housing parts to form the insulating housing.Since the housing parts thus provide the locking partners in a stable manner, the terminal can be provided as a whole with a comparatively low height compared to known terminals with a lockingly connected insulating housing.

[0008] Several or all of the first conductor insertion directions preferably extend in the same first extension plane. Thus, the housing upper part can be provided with a low overall height.

[0009] Alternatively or additionally, several or all of the second conductor insertion directions can extend in the same second extension plane. In this way, the housing base can also be provided with a correspondingly low height.

[0010] Particularly preferably, the first and the second extension planes are aligned parallel to each other, so that the insulating housing as a whole can be provided in a particularly compact and thus low-profile manner, which leads to an overall compact terminal.

[0011] Several or all of the first conductor insertion directions are preferably arranged side by side. Depending on the desired accessibility of the conductor insertion channels, the terminal, or at least its upper housing section, can be optimized as much as possible in terms of width and thus designed to be as compact as possible.

[0012] Several or all of the second conductor insertion directions can preferably be arranged side by side. Thus, the terminal as a whole, and preferably at least the housing base, can be optimized in width and thus designed to be compact.

[0013] Several or all of the first conductor insertion channels are preferably arranged in a first arrangement plane, which may be the same as the first extension plane.

[0014] This also preferably leads to a terminal that is as low as possible and thus as compact as possible by a correspondingly low design of the upper part of the housing.

[0015] Several or all of the second conductor insertion channels are preferably arranged in a second arrangement plane, which may be the same as the second extension plane. This allows the housing base to be designed to be correspondingly compact. In a particularly preferred embodiment, the first and second arrangement planes are aligned parallel to one another, which is advantageous for an overall particularly compact and thus low-profile terminal.

[0016] Several or all of the first conductor insertion channels are preferably arranged next to one another in a row, resulting in a compact design of the upper part of the housing.

[0017] Alternatively or additionally, several or all of the second conductor insertion channels can be arranged next to one another in a row, which is advantageous for a compact design of the housing base.

[0018] At least some of the first conductor insertion channels and at least some of the second conductor insertion channels are preferably accessible from the same side of the terminal. Thus, the terminal is designed to be particularly user-friendly in terms of ease of use, since appropriate cabling is enabled via a defined—and in this case, a common—side of the terminal. In principle, it is conceivable for the respective other part of the first or second conductor insertion channels to also be accessible from the same side of the terminal, which preferably lies opposite the previously described same side of the terminal of the respective one part of the first or second conductor insertion channels.

[0019] The first conductor insertion channels are preferably divided into a first group of first conductor insertion channels, which are particularly preferably arranged parallel to one another and in series next to one another, and into a second group of first conductor insertion channels, which are preferably arranged parallel to one another and in series next to one another. The first conductor insertion channels of the first group are preferably all accessible from a first side of the terminal, and the first conductor insertion channels of the second group are preferably all accessible from a second side of the terminal, which is preferably opposite the first side. Thus, a terminal for easy electrical feedthrough can be provided in a simple and compact manner. This is then particularly via the upper housing part.Furthermore, it is preferably conceivable that the second conductor insertion channels are also divided into a third group of second conductor insertion channels, which are preferably arranged parallel to one another and in series next to one another, and into a fourth group of second conductor insertion channels, which are preferably arranged parallel to one another and in series next to one another. The second conductor insertion channels of the third group can then preferably all be accessible from one or also the first side of the terminal. The second conductor insertion channels of the fourth group can then preferably all be accessible from one or the second side of the terminal, and particularly preferably the side opposite the first side. Thus, the second conductor insertion channels in the lower housing part can also be provided accordingly compactly and preferably for looping through simply and safely.

[0020] At least one of the locking pairs can be arranged between two first conductor insertion channels, viewed in the first conductor insertion direction, and / or between two second conductor insertion channels, viewed in the second conductor insertion direction. Thus, a space between the corresponding conductor insertion channels can be used for the mechanical connection of the housing parts of the insulating housing, allowing the terminal to be connected particularly securely despite its low profile.

[0021] The locking partner pairs can preferably each have a detent and a corresponding locking receptacle as respective locking partners, which can be positively connected to one another to achieve the locking connection. In this way, a structurally simple but secure locking connection can be provided.

[0022] At least one of the locking partners, preferably at least one of the detents, can preferably be designed to execute a flexible deflection movement parallel to one or all of the first conductor insertion directions and / or to one or all of the second conductor insertion directions to achieve the locking connection with the associated other locking partner, preferably the associated locking receptacle. The locking connection thus acts to lock in the conductor insertion direction, which enables an overall effective connection even during operation. If, in addition, any gaps between the conductor insertion channels are preferably utilized, a particularly compact terminal can be achieved while simultaneously ensuring a stable and secure connection between the housing parts.

[0023] At least one of the locking partners, preferably at least one of the detents, can preferably be designed to execute a flexible deflection movement transversely or perpendicularly to at least one or all of the first conductor insertion directions and / or to at least one or all of the second conductor insertion directions to achieve the locking connection with the associated other locking partner, preferably the associated locking receptacle. Such a locking connection enables a high connection effectiveness with the smallest possible installation space in terms of width.

[0024] The locking partner pairs preferably each have insertion bevels to achieve the flexible deflection movement when connecting the upper housing part to the lower housing part towards the locking connection. This allows the upper and lower housing parts to be easily brought together to create the locking connection, which also significantly facilitates automated production of the terminal.

[0025] The insulating housing, preferably the upper housing part and / or the lower housing part, can also have guide sections to guide the upper housing part and the lower housing part in a connecting direction into the locking connection by means of the locking partner pairs. This allows the insulating housing to be manufactured in a user-safe and thus preferably automated manner. This also helps prevent assembly errors during manual assembly.

[0026] The upper housing part can preferably have a first separating surface and the lower housing part can preferably have a second separating surface, which, when the insulating housing is connected - i.e. when the upper housing part and the lower housing part are connected in a locking manner by means of the locking partner pairs in the locking connection - at least partially abut one another in a separating plane separating the first and second conductor insertion channels. This makes it possible to provide an overall compact but stable design of the upper housing part and the lower housing part. The correspondingly large-area contact also enables a compact but secure connection of the terminal as a whole. This also has an appropriate effect on the stabilization of the locking partner pairs, which thus enable a highly effective locking connection despite the compact design of the terminal. Despite the compact design, defined clearance and creepage distances can thus be reliably maintained.

[0027] The upper housing part preferably has a first color, and the lower housing part preferably has a second color. Thus, the insulating housing can be designed in any desired manner and, for example, in separate colors corresponding to the first conductor entry channels and the second conductor entry channels. The first color and the second color are preferably different and particularly preferably complementary colors, so that the first conductor entry channels and the second conductor entry channels are clearly visible and distinguishable for an operator, which in turn increases user-friendliness and reduces the likelihood of incorrect assembly.

[0028] In principle, it is conceivable that at least the upper housing part and / or at least the lower housing part is or are made of a transparent material, so that, for example, the first or the second conductor terminal point is visible from the outside and a corresponding connection of a conductor can thus be visually checked.

[0044] The figures all show a terminal 1 according to the present invention. This terminal i can, in particular, be a connecting or connection terminal. The terminal i has a plurality of first spring-loaded terminal connections 2, each with a first conductor terminal point K1 for the electrical connection of a conductor (not shown here). Likewise, the terminal i shown here further has a plurality of second spring-loaded terminal connections 3, each with a second conductor terminal point K2 for the electrical connection of a conductor (also not shown here).

[0045] As exemplified in the illustrated embodiment, each of the spring-loaded terminal connections 2, 3 can have a busbar 20, 30 and a clamping spring 21, 31 with a movable clamping leg 22, 32 for each conductor clamping point Ki, K2. The clamping leg 22, 32 presses with a distal end or clamping edge against the busbar 20, 30 to form the respective conductor clamping point Ki, K2; consequently, between the clamping leg 22, 32 or its respective clamping section on the one hand and the busbar 20, 30 on the other. In this way, the corresponding conductor clamping points Ki, K2 can be provided. As also illustrated in the illustrated embodiment, at least some of the busbars 20, 30 can be formed integrally with one another. It is also conceivable for some of the clamping springs 21, 31 or their clamping legs 22, 32 to be formed integrally with one another.

[0046] The terminal 1 further comprises an insulating housing 6 which at least partially and here completely accommodates the spring-loaded terminal connections 2, 3, as can be seen in particular from the sectional views and Figures 13 and 14.

[0047] The insulating housing 6 is preferably made of a plastic, for example by an injection molding process.

[0048] The insulating housing 6 has, for each first conductor terminal point K1, a first conductor insertion channel 40 extending from the outside to the respective first conductor terminal point K1 in a first conductor insertion direction E1. Likewise, the insulating housing 6 has, for each second conductor terminal point K2, a second conductor insertion channel 50 extending from the outside to the respective second conductor terminal point K2 in a second conductor insertion direction E2.

[0049] As can be seen from all figures, and in particular from figures 11 to 14, the insulating housing 6 further comprises an upper housing part 4, which has the first conductor insertion channels 40; thus, it is completely enclosed. Furthermore, the insulating housing 6 comprises a lower housing part 5, which has the second conductor insertion channels 50; thus, it is completely enclosed. Thus, the first conductor insertion channels 40 and the second conductor insertion channels 50 are divided into two different housing parts, namely the upper housing part 4 on the one hand and the lower housing part 5 on the other, as a whole and functionally self-contained.

[0050] Preferably, several or, as shown here, all of the first conductor insertion directions Ei extend in the same first extension plane Xi. Likewise, several or, as shown here, all of the second conductor insertion directions E2 can extend in the same second extension plane X2. As shown here, the first and second extension planes Xi, X2 can be aligned parallel to one another. This can be seen in particular in Figure 4.

[0051] As shown here, several or alternatively all of the first conductor insertion directions E1 can be arranged next to one another. Similarly, as shown here, several or alternatively all of the second conductor insertion directions E2 can also be arranged next to one another, as can be seen by way of example in Figure 15.

[0052] Several or, as shown here, all of the first conductor insertion channels 40 can preferably be arranged in a first arrangement plane Yi, which preferably corresponds to the first extension plane Xi. Likewise, several or, as shown here, all of the second conductor insertion channels 50 can also be arranged in a second arrangement plane Y2, which preferably corresponds to the second extension plane X2. The first and second arrangement planes Yi, Y2 can particularly preferably be aligned parallel to one another. This can be seen in particular in Figure 4. As shown here, several or alternatively all of the first conductor insertion channels 40 can be arranged next to one another in a row.

[0053] In the exemplary embodiment illustrated here, the first conductor insertion channels 40 are divided, for example, into a first group G1 of first conductor insertion channels 40 and a second group G2 of first conductor insertion channels 40. In the exemplary embodiment illustrated here, each conductor insertion channel 40 of the first group G1 is assigned exactly one first conductor insertion channel 40 of the second group G2. Their conductor insertion directions Ei are preferably aligned coaxially with one another in the exemplary embodiment illustrated here. The first conductor insertion channels 40 thus aligned coaxially with one another preferably share a first busbar 20.

[0054] The first conductor insertion channels 40 of the first group G1 can preferably be arranged parallel to one another and in series next to one another, as shown in the illustrated embodiments. Likewise, the first conductor insertion channels 40 of the second group G2 can preferably be arranged parallel to one another and in series next to one another, as can also be seen by way of example in the illustrated embodiment.

[0055] The first conductor insertion channels 40 of the first group G1 can preferably all be accessible from a first side of the terminal 1. The first conductor insertion channels 40 of the second group G2 can preferably all be accessible from a second side of the terminal 1, preferably opposite the first side. This is shown in the illustrated embodiment.

[0056] As shown here, several or alternatively all of the second conductor insertion channels 50 can be arranged next to one another in a row.

[0057] According to the illustrated embodiment, it is conceivable that the second conductor insertion channels 50 are divided into a third group G3 of second conductor insertion channels 50 and a fourth group G4 of second conductor insertion channels 50. In this case, one of the second conductor insertion channels 50 of the third group is assigned to exactly one of the second conductor insertion channels 50 of the fourth group G4 such that their second conductor insertion directions E2 are aligned coaxially with one another. The second conductor insertion channels 50 of the third group G3 are preferably arranged parallel to one another and in a row next to one another, as shown in the illustrated embodiment. Likewise, the second conductor insertion channels 50 of the fourth group G4 can also preferably be arranged parallel to one another and in a row next to one another, as can also be seen from the illustrated embodiment.

[0058] The second conductor insertion channels 50 of the third group G3 can preferably all be accessible from one or the previously described first side of the terminal. Likewise, the second conductor insertion channels 50 of the fourth group G4 can preferably all be accessible from one or the previously described second side of the terminal 1, which is preferably opposite the first side.

[0059] Overall, it is preferably conceivable that at least some of the first conductor insertion channels 40 and at least some of the second conductor insertion channels 50 are accessible from the same side of the terminal 1. In the exemplary embodiment illustrated here, for example, five first conductor insertion channels 40 and five second conductor insertion channels 50 are accessible from a first side of the terminal 1, and likewise five first and second conductor insertion channels 40, 50 are accessible from a second side of the terminal 1 opposite the first side.

[0060] The insulating material housing 6 further comprises locking partner pairs 7 distributed over the housing upper part 4 and the housing lower part 5 in order to connect the housing upper part 4 and the housing lower part 5 in a locking connection, as can be seen in particular from Figures 1 to 8.

[0061] At least one of the locking partner pairs 7 is preferably arranged between two first conductor insertion channels 40, viewed in the first conductor insertion direction E1, and / or between two second conductor insertion channels 50, viewed in the second conductor insertion direction E2. For example, with reference to Fig. 2, in the illustrated embodiments, each of the end-side locking partner pairs 7 is arranged between two first conductor insertion channels 40 and between two second conductor insertion channels 50, viewed in the conductor insertion directions E1, E2.

[0062] The locking partner pairs 7 preferably each have a catch 70 as one of the locking partners 7 per locking partner pair and a locking receptacle 71 as the other locking partner per locking partner pair 7, which can be positively connected to one another to achieve the locking connection, as can be seen, for example, in Figures 4 to 6.

[0063] At least one of the locking partners 70, preferably at least one of the detents 70, is preferably designed to execute a flexible deflection movement parallel to one or all of the first conductor insertion directions E1 and / or to one or all of the second conductor insertion directions E2 to achieve the locking connection with the associated other locking partner 71, preferably the associated locking receptacle 71. In the illustrated embodiment, this applies to the locking partner pairs 7 provided here on the front side, which are viewed from the front in Fig. 2, for example.

[0064] At least one of the locking partners 70, preferably at least one of the detents 70, can preferably be designed to execute a flexible deflection movement transversely or here perpendicular to at least one or all of the first conductor insertion directions E1 and / or to at least one or all of the second conductor insertion directions E2 to achieve the locking connection with the associated other locking partner 71, preferably the associated locking receptacle 71. This applies in particular to the locking partner pairs 7 provided laterally here, which flank the sides of the terminal 1 in the exemplary embodiment shown here and can be seen by way of example in Figures 2, 3, 5, 7, 9 and 11 to 14.

[0065] The locking partner pairs 7 each have insertion bevels 72, 73 to achieve the flexible deflection movement when connecting the housing upper part 4 to the housing lower part 5 towards the locking connection, as can be seen by way of example in Figures 4 to 6.

[0066] The insulating material housing 6 and preferably the housing upper part 4 or the housing lower part 5 can further have guide sections 8 in order to transfer the housing upper part 4 and the housing lower part 5 in a connection direction V into the locking connection by means of the locking partner pairs 7, wherein preferably the locking partner pairs 7 - or their locking partners 70, 71 - can have at least part of the guide sections 8.

[0067] As can be seen in particular from Figures 11 to 14, the housing upper part 4 can have a first separating surface Ti and the housing lower part 5 can have a second separating surface T2, which, in the connected state of the insulating material housing (cf. for example Figure 4), at least partially abut one another in a separating plane TE separating the first and second conductor insertion channels 40, 50.

[0068] The upper housing part 4 can preferably have a first color, and the lower housing part 5 can preferably have a second color. The colors can be identical. However, it is also conceivable for the first color and the second color to be different and particularly preferably have complementary colors. Thus, the two components, and thus in particular the first conductor insertion channels 40, which are distributed here as a whole among the respective housing parts, on the one hand, and the second conductor insertion channels 50, on the other hand, can be provided in a highly distinguishable manner, which significantly increases the ease of use of the terminal 1.

[0069] At least the upper housing part 4 and / or the lower housing part 5 can be made of a transparent material.
