Summary of the Invention

Problems to be Solved by the Invention

[0005] Based on this, an object of the present invention is to provide an improved conductor connection terminal.

Means for Solving the Problems

[0006] The problem is solved by using a conductor connection terminal having the features of claim 1. Advantageous embodiments are described in the dependent claims. Also, in the case of a general conductor connection terminal, it has been proposed to arrange a second locking connection portion between the closing member and the contact insert, and to enable the closing member and the contact insert to be locked to each other by the second locking connection portion.

[0007] By forming a second locking connection portion between the closing member and the contact insert, it is possible to provide a conductor connection terminal that can be safely handled in a pre-attached state. Double locking, that is, double locking of the closing member to the insulating housing and the closing member to the contact insert, enables the provision of a pre-attached unit composed of at least the closing member and the contact insert, and makes it possible to provide a more stable conductor connection terminal. Therefore, deformation of the conductor connection terminal due to the influence of force is eliminated or reduced.

[0008] Furthermore, even when an external force such as a tensile force or a torsional force acts on the conductor connection terminal, the closing member is surely held by the insulating housing. The clamping spring can have a contact leg and a spring arch disposed between the contact leg and the clamping leg.

[0009] Various embodiments of the first locking connection portion and the second locking connection portion are shown below. The locking connection portion of the conductor connection terminal is not limited to one of the present embodiments. Rather, these locking connection portions may be configured in combination with the conductor connection terminal, or may be configured with an increased number. For example, it is conceivable that at least one, two, or three locking connection portions of the same type are configured in the conductor connection terminal according to the present invention.

[0010] The second locking connection part can be configured as a locking arm of the closing member, and the locking arm engages with the bus bar of the contact insert. At this time, the locking arm is arranged on the closing member. When the closing member and the contact insert are attached, the locking arm is guided to pass through the contact insert, and the end of the locking arm engages with the contact insert, thereby securely locking the contact insert to the closing member. Here, two locking arms are arranged on the closing member, and the locking arms are respectively guided to pass through the opposing surfaces of the contact insert, and it is useful for the locking arms to engage around the contact insert. Preferably, a locking hook that engages from behind the locking edge of the bus bar can be provided on the locking arm.

[0011] The insulating housing can have a blocking member, and the blocking member prevents the locking member from coming off. It is also conceivable that the insulating housing itself is the blocking member. When the contact insert and the pre-attached closing member are guided into the insulating housing, the insulating housing prevents the second locking connection part from coming off.

[0012] For example, the aforementioned configuration of the second locking connection part as a locking arm is blocked by the presence of the insulating housing and / or the blocking member and can no longer be displaced. In this way, a conductor connection terminal that is functionally highly reliable and can be safely handled is provided, and the second locking connection part cannot be released without removing the closing member from the insulating housing.

[0013] The first locking connection part can be configured as a locking hook of the insulating housing, and the locking hook engages with the opening of the closing member. Here, the locking hook is arranged on the insulating housing. The locking hook can be guided to the opening of the closing member, where the locking hook locks the insulating housing to the closing member.

[0014] It is conceivable that there is a certain interval between the closing member and the insulating housing so that the closing member deflects (durchfedern) when the insulating housing is attached to the closing member.

[0015] The first locking connection part can be configured as a tab of the closing member, and the tab engages with the web of the insulating housing. At this time, the tab is arranged on the closing member, and the tab is configured as a flat material piece having a mounting hole. When the closing member is attached to the insulating housing, the tab is guided through the web of the insulating housing, the web reaches the mounting hole, and there the closing member is locked to the insulating housing.

[0016] The first locking connection part can be configured as a protrusion of the closing member, and the protrusion engages with the recess of the insulating housing. In particular, the protrusion may be T-shaped. In this case, the protrusion is arranged on the closing member, and when the closing member is attached to the insulating housing, the closing member is guided into the recess of the insulating housing. The possible T-shaped configuration of the protrusion can prevent loosening of the first locking connection part. Therefore, the connection can be released without breaking the conductor connection terminal any more.

[0017] Such a configuration of the locking connection part can occur in each possible combination. For example, the first locking connection part can be configured as three protrusions of the closing member, and one of the protrusions can be configured in a T-shape. However, it is also conceivable that a tab is arranged on the closing member and two locking hooks are arranged on the insulating housing, and each locking hook engages with the opening of the closing member. By various combinations of the locking connection parts, a conductor connection terminal that can be safely handled can be provided.

[0018] An inspection opening can be arranged in the closing member. Here, the inspection opening can be aligned laterally with respect to the conductor to be clamped, and the inspection opening extends from the surface of the closing member through the closing member to the contact insert. Through such an inspection opening, the contact insert can be brought into contact with an external measuring device.

[0019] The conductor connection terminal may have at least one, preferably two operating levers, which are arranged to displace the clamping legs. Thereby, the opening and closing of the clamping position can be easily carried out without further providing auxiliary means.

[0020] The conductor connection terminal may have a guide contour for guiding the first locking connection part and / or the second locking connection part. In particular, the guide contour may be an inclined surface of the insulating housing and / or the closing member. Such a guide contour facilitates the installation of the conductor connection terminal. For example, the opening of the closing member may have an inclined surface, where the locking hook of the insulating housing may be guided to the locking position via the inclined surface.

[0021] The insulating housing and the closing member may be caulked to each other in the region of the first locking connection part. When the closing member is mechanically caulked to the insulating housing, plastic deformation of the closing member and / or the insulating housing occurs, but the components can be prevented from coming off each other, and the components are not destroyed by the corresponding force consumption.

[0022] The first locking connection part and / or the second locking connection part may be arranged in the central region of the conductor connection terminal. Here, the conductor connection terminal may have a symmetric structure in which the first locking connection part and / or the second locking connection part is arranged on the symmetry plane of the conductor connection terminal. In particular, the first locking connection part and / or the second locking connection part may be arranged on the symmetry plane of the conductor connection terminal, and the symmetry plane extends perpendicular to the conductor insertion direction.

[0023] In this way, a completely symmetric conductor connection terminal can be provided, and the manufacture of such a completely symmetric conductor connection terminal is simplified. The conductor connection terminal may have two conductor insertion openings and two clamping springs, and the conductor insertion openings are arranged at opposite ends of the conductor connection terminal facing each other. In particular, the first locking connection part and / or the second locking connection part may be arranged between the clamping springs of the contact insert. Alternatively or additionally, in particular, the first locking connection part between the closing member and the insulating housing is provided in the end regions facing each other on opposite sides in the longitudinal extension direction of the conductor connection terminal, and thus may also be provided outside the symmetry plane of the conductor connection terminal. Here, the longitudinal extension direction is the direction in which the conductor is inserted into the conductor insertion opening.

[0024] In this way, a conductor terminal having two opposing clamping positions for two conductors can be provided, and the conductor terminal has high stability against deformation of the insulating housing and / or the closing member. This means, in particular, that the insulating housing and / or the closing member do not deform plastically and / or elastically under the action of force, for example under the tension of the inserted conductor, and it means that the components are reliably held in their relative positions.

[0025] One of the above conductor connection terminals can be attached by a method including the following steps. - Attaching the clamping spring to the busbar; - Locking the contact insert to the closing member; - Inserting the closing member into the mounting opening of the insulating housing; - Fixing the insulating housing to the closing member; - Crimping the closing member to the insulating housing in the region of the first locking connection part.

[0026] By attaching the conductor connection terminal according to the present invention in this way, a conductor connection terminal that cannot be removed by the action of an external force can be provided. Through double locking, a very stable connection is achieved, and this connection will no longer become loose even by subsequent caulking. Therefore, the user can no longer remove the conductor connection terminal that may be damaged if removed.

[0027] The indefinite article "ein" should be understood as an indefinite article, not a numeral. Therefore, it is also conceivable that a plurality of contact inserts are arranged adjacent to each other in the conductor connection terminal according to the present invention. For example, 2, 3, 4, or 5 contact inserts can be arranged adjacent to each other in the insulating housing, and each contact insert has two clamping springs for two conductors to be clamped.

[0028] Hereinafter, the present invention will be described in detail with reference to examples by using the accompanying drawings illustratively.

DETAILED DESCRIPTION OF THE INVENTION

[0030] FIG. 1 shows a conductor connection terminal 1 in a perspective view according to the first embodiment. The base of the conductor connection terminal 1 is formed by an insulating material housing 2 and a closing member 3, and the closing member 3 is inserted into the mounting opening of the insulating material housing 2. The conductor connection terminal 1 has two conductor insertion openings 4a, 4b for accommodating conductors.

[0031] Furthermore, it can be seen that there are two operating levers 5a, 5b, and the operating levers 5a, 5b are arranged on the closing member 3. An inspection opening 6 is arranged on the closing member 3, and the inspection opening 6 extends vertically from the surface of the closing member 3 into the interior of the insulating material housing 2. Such an inspection opening enables access to the conductive member in the insulating material housing 2 using an external measuring device.

[0032] It is clear that the closing member 3 is fixedly connected to the insulating material housing 2 via a first locking connection portion 7. Here, the first locking connection portion 7 is configured as a protrusion 8 of the closing member 3, and the protrusion 8 engages with a recess 9 of the insulating material housing 2, thereby fixing the closing member 3 to the insulating material housing 2.

[0033] It can be seen that the conductor connection terminal 1 is configured to be completely symmetric with respect to the symmetry plane SE, and the first locking connection portion 7 is arranged on the symmetry plane SE. Here, the symmetry plane SE extends perpendicular to the conductor insertion direction L.

[0034] Figure 2 shows the closing member 3 of the conductor connection terminal 1 in the perspective view according to Figure 1, with the operating levers 5a and 5b arranged thereon. It is clear that the second locking connection portion 10 is arranged on the closing member 3 and is configured as a locking arm 11. The second locking connection portion is provided for locking the closing member 3 to the contact insert (in other words, the insertion member) 12. Here, the second locking connection portion 10 is arranged on the same symmetry plane SE as the first locking connection portion 7. By means of double locking, that is, locking of the closing member 3 to the insulating material housing 2 and locking of the closing member 3 to the contact insert 12, a conductor connection terminal 1 that can be safely handled can be provided.

[0035] Furthermore, it can be seen that two protrusions 8 provided for engaging with the recess 9 of the insulating material housing 2 are arranged on opposite sides of the closing member 3. Figure 3 shows the conductor connection terminal 1 according to Figure 1 in a cross-sectional view, the cross-section of which is located in the plane of the symmetry plane SE. It can be seen that the bus bar 13 of the contact insert 12 is arranged inside the insulating material housing 2, and the second locking connection portion 10 configured as a locking arm 11 is guided laterally along the bus bar 13 and engages around the bus bar 13. The first locking connection portion 7 configured as a protrusion 8 engages with the recess 9 of the insulating material housing 2. Thereby, double locking of the closing member 3 with respect to the contact insert 12 and the insulating material housing 2 is achieved.

[0036] The insulating material housing 2 is configured as a blocking member 14, and it becomes clear that a part of the insulating material housing 2, preferably the side wall, blocks the displacement of the locking arm 11, thereby preventing the second locking connection portion 10 from coming off. That is, the locking arm 11 of the second locking connection portion 10 is configured to come off from the bus bar 13 only when the first locking connection portion 7 has come off from the insulating material housing 2 in advance. The locking arm 11 of the second locking connection portion 10 is blocked by the presence of the insulating material housing 2.

[0037] The closing member 3 of the conductor connection terminal 1 shown in FIGS. 1 to 3 is not caulked to the insulating material housing 2 in the region of the first locking connection portion 7. However, caulking can be performed, for example, by applying a force F to the protrusion 8 of the closing member 3. As a result, the protrusion 8 is deformed such that a part of the protrusion 8 flows into the free region (in other words, the gap portion) 9a of the recess 9, and the first locking connection portion 7 can no longer be removed. Then, the protrusion 8 of the first locking connection portion 7 can no longer be pulled out from the recess 9 due to the deformation of the protrusion 8. After the closing member 3 is caulked to the insulating material housing 2, it is no longer possible to remove the conductor connection terminal 1 without breaking it.

[0038] FIG. 4a shows the conductor connection terminal according to FIG. 1 in a side cross-sectional view. The conductor connection terminal has an insulating material housing 2 and a closing member 3, and a contact insert 12 is disposed inside the insulating material housing 3.

[0039] The contact insert 12 has a bus bar 13 and two clamp springs 17a, 17b. The clamp springs 17a, 17b are disposed at opposite ends of the bus bar 13 facing each other. The clamp springs 17a, 17b each have a contact leg 18a, 18b, and the contact legs 18a, 18b transition to spring arches 19a, 19b and extend to clamp legs 20a, 20b. The clamp legs 20a, 20b each have a spring clamp edge 21a, 21b, and the spring clamp edges 21a, 21b together with the bus bar 13 form a clamping position for the conductor to be clamped.

[0040] The conductor connection terminal 1 has two operating levers 5a, 5b. Since each operating lever 5a, 5b interacts with the clamp springs 17a, 17b, the operating levers 5a, 5b are installed to displace the clamp legs 20a, 20b.

[0041] It is clear that a further first locking connection part 7a between the closing member 3 and the insulating housing 3 is configured as a locking hook 22 of the insulating housing 2. Here, the locking hook 22 is arranged at the end part facing the opposite side in the insulating housing 2. The locking hook 22 engages with the corresponding opening 23 of the closing member 3, and thus locks the insulating housing 2 and the closing member 3 to each other. This additional locking connection part 7a is thus made in the end region facing each other on the opposite side in the conductor connection terminal 1. This additional locking connection part 7a is optional and can be omitted when the requirement for locking the closing member 3 to the insulating housing 2 is low. The further first locking connection part 7a can be ensured not to come off by caulking a protrusion or the insulating housing 2.

[0042] Figure 4b is an enlarged cross-sectional view of the conductor connection terminal according to Figure 4a. Here, the region of the first locking connection part 7a is enlarged and shown. It is clear that inclined surfaces (in other words, chamfered parts) 24 are arranged on the insulating housing 2 and the locking hooks 7a, 22. These inclined surfaces 24 function as a guiding contour for guiding the locking hook 22 of the first locking connection part 7a into the opening 23 of the closing member 3. Here, the locking hook slides to its locking position along the inclined surface 24, thereby fixing the insulating housing 2 to the closing member 3.

[0043] Figure 5 shows the conductor connection terminal 1 in the second embodiment in a perspective view. Here, the conductor connection terminal 1 in Figure 5 has the same structure as the conductor connection terminal 1 in Figure 1. Here, only the first locking connection part 7 of the conductor connection terminal 1 in Figure 5 is different from the conductor connection terminal 1 in Figure 1.

[0044] The first locking connection part 7 is configured as a tab 15, and the tab 15 is arranged on the closing member 3 of the conductor connection terminal 1. The tab 15 is configured as a flat material part piece having a mounting hole 16. A web 17 is arranged on the insulating housing 2, and the tab 15 engages with the web 17, so that the web 17 is locked by the mounting hole 16, fixing the closing member 3 to the insulating housing 2.

[0045] FIG. 6 shows the conductor connection terminal 1 in the third embodiment in a perspective view. Here, the conductor connection terminal 1 in FIG. 6 is configured to be identical to the conductor connection terminal 1 in FIGS. 1 and 5. The configuration of the first locking connection portion 7 of the conductor connection terminal 1 in FIG. 6 is different from that of the conductor connection terminals 1 in FIGS. 1 and 5.

[0046] In addition to the first locking connection portion 7, the conductor connection terminal 1 of the second embodiment according to FIG. 5 and the conductor connection terminal 1 of the third embodiment according to FIG. 6 preferably further include a second locking connection portion 10 corresponding to the example of the first embodiment according to FIGS. 1 to 4. More preferably, the conductor connection terminals of the second and third embodiments have additional or alternative further locking connection portions 7a corresponding to FIGS. 4a and 4b.

[0047] The first locking connection portion 7 has three protrusions 8 on the sides of the conductor connection terminal 1 facing each other, and these protrusions 8 are respectively engaged with the recesses 9 of the insulating material housing 2. It can be seen that one of the protrusions 8 is configured in a T shape. The T-shaped configuration of one of the protrusions 8 prevents displacement of the wall of the insulating material housing 2 by the undercut formed between the closing member 3 and the insulating material housing 2, and thus acts against loosening of the locking connection portion 7.

[0048] FIG. 7 shows the conductor connection terminal 1 according to FIG. 6 in a top view. The T-shaped configuration of the protrusion 8 is clear, which makes it more difficult to remove the closing member 3 from the insulating material housing 2. Here, since the recess 9 of the insulating material housing 2 is configured such that the insulating material housing 2 engages with the T shape of the protrusion 8 from the rear, the protrusion 8 is blocked in all degrees of freedom except one.

[0049] Furthermore, if the unblocked degree of freedom is blocked by another protrusion 8, it becomes impossible to remove the closing member 3 from the insulating material housing 2 without breaking the conductor connection terminal 1. FIG. 8 shows a contact insert 12 for use with one of the above-described conductor connection terminals 1. This contact insert 12 has a bus bar 13, and clamp springs 17a, 17b are arranged at opposite ends of the bus bar 13. The clamp springs 17a, 17b each have contact legs 18a, 18b that transition to spring arches 19a, 19b and extend to clamp legs 20a, 20b. Here, the clamp legs 20a, 20b extend toward the bus bar 13, and the clamp legs 20a, 20b have spring clamp edges 21a, 21b, forming a clamping position for the conductor to be clamped with the bus bar 13.

[0050] It can be seen that conductor receiving portions 25 for the conductors to be clamped are respectively arranged at opposite ends of the bus bar 13. It is clear that the conductor receiving portions 25 are configured to be closed in the circumferential direction.

[0051] Furthermore, two holding portions 27a, 27b are arranged on the upper surface 26 of the bus bar 13, and it can be seen that the holding portions 27a, 27b are respectively arranged at opposite ends on the upper surface 26. In the holding portions 27a, 27b, one of the clamp springs 17a, 17b is held in a floating state in a self-supporting manner, that is, without additional mounting means.

[0052] However, it is also conceivable that the clamp springs 17a, 17b are configured as a single clamp spring having two clamp legs 20a, 20b, and each clamp spring extends on the upper surface 9 of the bus bar 13.

[0053] FIG. 9 shows an exploded view of the conductor connection terminal 1 in the first embodiment according to FIG. 1. It can be seen that the contact insert 12 according to FIG. 8 can be inserted into the insulating material housing 2 of the conductor connection terminal 1.

[0054] It is clear how the conductor connection terminal 1 according to the present invention can be attached. In the first step, the locking member 3 is locked to the bus bar 13 of the contact insert 12 using the locking arm 11 formed as the second locking connection portion 10. Here, the locking arm 11 engages under the U-shaped bus bar 13.

[0055] In the second step, the operating levers 5a, 5b are attached to the locking member 3 and the contact insert 12. This second step can optionally also be performed before the first step.

[0056] In the third step, the pre-mounted unit for the insulating housing 2 having the locking member 3, the contact insert 12 and the operating levers 5a, 5b can be inserted into the insulating housing 2 through the mounting opening 28. Here, the insulating housing 2 is fixed to the locking portion 3 by the first locking connection portion 7 and the further first locking connection portion 7a. Here, the first locking connection portion 7 is arranged on the locking member 3, and the further first locking connection portion 7a is arranged on the insulating housing 2.

[0057] It is clear that the first locking connection portion 7 engages with the corresponding recess 9 of the insulating housing 2. Here, the locking member 3 is fixed to the insulating housing 2. The further first locking connection portion 7a further supports this fixing. Here, the recess 9 is configured with a closed circumferential direction. This particularly means that the first locking connection portion 7 can only be guided in the recess 9 with one degree of freedom.

[0058] In an optional fourth step, the locking member 3 can be caulked to the insulating housing 2 in the region of the first locking connection portion 7 and / or the further first locking connection portion 7a.
