Description

The invention relates to a fastening device for fastening several individual single-pole and/or multi-pole connection terminals to one another and/or to a holder of the fastening device.

Such a fastening device is e.g. B. from the WO 2020/152023 A1 known.

The invention is based on the object of providing further universally applicable options for attaching conductor connection terminals.

1. a) die Befestigungsvorrichtung weist wenigstens einen Klebestreifen auf, mit dem wenigstens zwei Leiteranschlussklemmen durch Kleben aneinander und/oder wenigstens eine Leiteranschlussklemme durch Kleben an der Halterung befestigbar sind,
2. b) die Halterung weist mehrere einzelne Segmente auf, an denen jeweils eine oder mehrere Leiteranschlussklemmen durch Verrasten befestigbar sind, wobei wenigstens zwei zueinander unmittelbar benachbarte Segmente durch wenigstens ein Filmscharnier miteinander verbunden sind,
3. c) die Halterung weist mehrere Aufnahmeplätze auf, an denen jeweils eine Leiteranschlussklemme durch Verrasten befestigbar ist, wobei die Halterung erste Rastelemente aufweist, die zum rastenden Zusammenwirken mit zweiten Rastelementen an Seitenwänden der Leiteranschlussklemme eingerichtet sind, die sich parallel zur Leitereinführrichtung der Leiteranschlussklemme und orthogonal zur Unterseite der Leiteranschlussklemme erstrecken,
4. d) die Halterung ist als gitterförmige Aufnahmevorrichtung ausgebildet, in der nach Art einer Matrix eine Vielzahl von Fächern ausgebildet ist, wobei in einem Fach jeweils eine Leiteranschlussklemme aufnehmbar ist.

This object is achieved by a fastening device for fastening several individual single-pole and/or multi-pole conductor connection terminals to one another and/or to a holder of the fastening device, with one, several or all of the following features a), b), c), d):

1. a) the fastening device has at least one adhesive strip with which at least two conductor connection terminals can be fastened to one another by gluing and/or at least one conductor connection terminal can be fastened to the holder by gluing,
2. b) the holder has several individual segments, to which one or more conductor connection terminals can be attached by latching, with at least two immediately adjacent segments being connected to one another by at least one film hinge,
3. c) the holder has a plurality of receiving locations, at each of which a conductor connection terminal can be fastened by latching, the holder having first latching elements which are set up for latching interaction with second latching elements on side walls of the conductor connection terminal, which are parallel to the conductor insertion direction of the conductor connection terminal and orthogonal to the extend underside of the conductor connection terminal,
4. d) the holder is designed as a grid-shaped receiving device in which a plurality of compartments are formed in the manner of a matrix, with a conductor connection terminal being able to be accommodated in each compartment.

Using the adhesive fastening according to feature a), the conductor connection terminals and their housings can be attached directly to one another. In this way, single-row or multi-row blocks of conductor connection terminals can be put together quickly and easily. Furthermore, one or more conductor connection terminals can be attached to the holder by gluing. This can also be achieved in a simple way, e.g. B. using a double-sided adhesive strip. In this way, modular connection modules can, for example, be glued together over the side surfaces of the housing, so that multi-pole connection connectors or socket terminals can be formed. By gluing, row, stack or matrix arrangements can be created.

The individual segments according to feature b), which are connected to one another by at least one film hinge, can be adjusted in terms of their position to one another through this connection, so that the conductor connection terminals can be arranged in different spatial configurations using such a flexibly adjustable holder. In addition, the holder can be easily separated in the area of a film hinge, so that the holder can be made to a desired size with little effort. The film hinge, also known as a film hinge, can e.g. B. be made of the same material as the individual segments, e.g. B. made of a plastic material. The film hinge then differs from the individual segments in its significantly smaller material thickness. However, the film hinge can also be made from another film or foil-like material.

Advantageously, the holder can therefore be tailored to the desired number of poles. The holder can be folded over and thus allows conductor connection terminals to be used in double rows. The holder can, for example, be wrapped around a rod or a tube and attached to it. The holder can also adapt to the shape of the surface, which e.g. B. is advantageous for corner installation or on uneven surfaces. The segments connected by a film hinge can, for example, be manufactured as a one-piece arrangement, e.g. B. through a plastic injection molding process.

According to feature c), the conductor connection terminal is fixed to the holder laterally, i.e. H. not on the front sides of the conductor connection terminal where there are conductor entry openings. This has the advantage that the first latching elements do not hinder the insertion of electrical conductors into the conductor guide openings. In addition, the second latching elements can be provided on the side walls of the conductor connection terminal at locations where there is sufficient space for them.

For example, there can be rigid bars between the recording locations so that the holder can be separated at these locations. This makes it possible for the user to separate parts with the desired number of poles from a long strip-shaped holder, similar to luster terminal blocks. The receiving places can also have a lock in the longitudinal direction, through which a conductor connection terminal attached there is fixed in a defined position at the receiving place in the longitudinal direction, ie parallel to the conductor insertion direction. For example, the adjacent receiving locations can have longitudinal locks through which the conductor connection terminals attached there are arranged at the same height. For example, all recording spaces can have the same width.

The grid-shaped receiving device according to feature d) can also be provided very easily and inexpensively, e.g. B. as a plastic component. Due to the matrix shape, the holder allows a large number of conductor connection terminals to be accommodated in a small space. The compartments of the grid-shaped receiving device in turn form receiving spaces for conductor connection terminals.

The fastening device is particularly suitable for conductor connection terminals, each of which has an operating lever for actuating a spring-loaded terminal connection of the conductor connection terminal. The operating levers each have an operating section for manual operation, i.e. H. for pivoting the operating lever. In an advantageous embodiment, the actuation sections are located on an upper side of the conductor connection terminal, i.e. H. on the housing side of the conductor connection terminal facing away from the bottom.

According to an advantageous embodiment of the invention, it is provided that the fastening device for fastening conductor connection terminals is designed in the form of through-connection terminals, in which conductor insertion openings for inserting electrical conductors are formed on end faces of the housing facing away from one another. Such through-connection terminals can be realized in a very slim design and are particularly suitable for a multi-row, stacked or matrix-like arrangement.

According to an advantageous embodiment of the invention, it is provided that the adhesive strip is designed as an adhesive strip coated on both sides with adhesive. Such an adhesive strip attachment allows the conductor connection terminals to be separated from each other again if necessary.

According to an advantageous embodiment of the invention, it is provided that the holder is set up for modification into different spatial arrangements by folding a segment over its film hinge relative to the immediately adjacent segment. If several segments are arranged next to each other and are each connected to one another by at least one such film hinge, the entire arrangement can be adapted relatively flexibly in terms of its spatial design, e.g. B. to a ring-shaped arrangement or to an angled arrangement for corner mounting.

According to an advantageous embodiment of the invention, it is provided that the holder has a strain relief plate on at least one conductor insertion side of the conductor connection terminals, to which the electrical conductors connected to the conductor connection terminals can be fixed for strain relief. The strain relief plate can be formed in one piece with a receiving area of the holder on which the conductor connection terminals are arranged. The strain relief plate can also be designed as a separate component, e.g. B. is connected to the receiving area by latching, screwing or gluing.

According to an advantageous embodiment of the invention, it is provided that at least one fixing element is present in a respective compartment of the grid-shaped receiving device, which cooperates with a fixing element assigned as a counterpart on the housing of the conductor connection terminal, so that a conductor connection terminal can be fixed in several different longitudinal positions within a compartment. In this way, the conductor connection terminals can be reliably fixed in the respective compartments. The fixation via the fixing element can, for example, be designed in such a way that the fixation can be overcome again by increasing the effort. In this way, if necessary, the conductor connection terminal can be pushed out of a compartment on one side, for example, in order to connect an electrical conductor there on the pushed-out side, and then pushed back into the compartment.

According to an advantageous embodiment of the invention, it is provided that the grid-shaped receiving device is formed by cross-assembling locking elements provided with slots. In this way, the receiving device can only be assembled when necessary, and assembly can be done very simply by plugging the locking elements together. The locking elements can be designed as pre-assembled standard components that can be shortened to the desired length by the user as required to provide a grid-shaped receiving device of a desired size.

According to an advantageous embodiment of the invention, it is provided that several individual single-pole and/or multi-pole conductor connection terminals are fastened to one another and/or to the holder of the fastening device. The conductor connection terminals are fastened according to one, several or all of the features a), b), c) or d) mentioned at the beginning.

For the purposes of the present invention, the indefinite term “a” is not to be understood as a numeral. For example, if we are talking about a component, this should be interpreted in the sense of “at least one component”. If angle information is given in degrees, these refer to a circular measure of 360 degrees (360°).

The invention is explained in more detail below using exemplary embodiments using drawings. Show it

• 2 a grid-shaped receiving device,
• 3 the attachment of conductor connection terminals in compartments of the grid-shaped receiving device,
• 4 a holder with several recording locations,
• 5 a holder with individual segments,

The 1 shows locking elements 10 with which a grid-shaped receiving device according to 2 can be produced. The locking elements 10 can z. B. be designed as a plastic component. The locking elements 10 have slots 11 on one side, which are z. B. extend into the material up to approximately the middle of the locking element. The slots 11 can z. B. be arranged at equal distances from one another. These slots 11 also form a predetermined breaking point 12, which forms a separation point for cutting the locking element to a desired length.

The locking elements 10 are off 1 put together crosswise in opposite directions, the in 2 grid-shaped recording device 20 shown can be generated with it. Compartments 21 are then formed in the grid-shaped receiving device 20, in which respective conductor connection terminals 1 can be inserted. In the compartments 21 there can be lateral locking knobs with which the conductor connection terminals used are fixed.

The 3 shows a section of a grid-shaped recording device 20 in a partially sectioned view. In particular, the side walls 30 of the grid-shaped receiving device, which laterally delimit the respective compartments 21, are shown in section. You can see the lateral locking knobs 31 arranged on the walls 30, which can engage in a corresponding recess 32 in the housing 2 of the conductor connection terminal 1. Because three locking knobs 31 are arranged one behind the other, the conductor connection terminal can be fixed in three different longitudinal positions.

The top figure in 3 shows that the conductor connection terminal 1 is fixed in a first position in which the left area of the conductor connection terminal 1 protrudes from the compartment 21. In this state, for example, an actuating lever of the conductor connection terminal 1 can be actuated, with which a spring-loaded terminal connection is opened. An electrical conductor 33 can then be inserted from the left side and connected to the spring-loaded terminal connection. The operating lever is then moved into the closed position and the conductor connection terminal 1 is moved into the center of the 3 second position shown shifted. In this position, the right area of the conductor connection terminal 1 protrudes from the compartment 21. An electrical conductor can now be connected in a comparable manner in the right area. If electrical conductors 33 are connected on both sides, the conductor connection terminal 1 can be moved to the desired end position, ie a central position, and fixed there via the locking knobs 31, as shown in the figure below 3 is shown. If, as shown, there are several locking knobs 31 one behind the other, the conductor connection terminal 1 can also be fixed in the temporary positions, ie the first and second positions.

The 4 shows a fastening device with a holder 40, which has several receiving locations 41 for receiving conductor connection terminals. The holder 40 has first locking elements, the function of which is explained below using the 5 is explained. In addition, the holder 40 has a strain relief plate 42, to which the electrical conductors that are connected to the conductor terminals 1 can be fixed for strain relief.

The 5 shows a holder 40, in which the individual recording locations 41, as mentioned above, are present. The receiving locations have respective lateral first locking elements 45, which are designed to snap together with second locking elements on side walls of the conductor connection terminal 1.

Additionally shows the 5 that the holder 40 can be segmented into several individual segments 43. Each adjacent segment 43 is connected to one another by at least one film hinge 44. This film hinge connection creates a variety of possibilities for varying the shape of the holder 40 and thus the entire fastening device. As the 6 and 7 show, the holder 40 can be deformed into a triangular or square shape, for example by folding over the individual segments 43; other shapes are also possible. In addition, the respective arrangement can be fixed by a rod or a tube 60 passed through the middle.

As the 8th shows, the holder 40 can also be formed into any irregular shapes, for example to be applied to an uneven surface 80. The 9 shows that the bracket 40 can also be folded into a form of a two-story terminal.

In a further embodiment of the invention, the 10 until 12 that the individual conductor connection terminals 1 can also be attached directly to one another, in particular by gluing using an adhesive strip 100. In this way, single-story arrangements of conductor connection terminals ( 10 , 11 ) or multi-story arrangements ( 12 ) form.

The 13 shows a conductor connection terminal 1 in a perspective view. The base body of the conductor connection terminal 1 is formed from a housing 2 and a closure part 3, the closure part 3 being inserted into a mounting opening in the housing 2. The conductor connection terminal 1 has two conductor insertion openings 4a, 4b for receiving electrical conductors.

Furthermore, two operating levers 5a, 5b can be seen, the operating levers 5a, 5b being arranged on the closure part 3. A test opening 6 is arranged on the closure part 3, the test opening 6 extending vertically from a surface of the closure part 3 into the interior of the housing 2. Such a test opening allows access to electrically conductive components within the housing 2 with external measuring devices.

It is clear that the closure part 3 is fixedly connected to the housing 2 via a first latching connection 7. The first latching connection 7 is designed as a projection 8 of the closure part 3, the projection 8 engaging in a recess 9 of the housing 2 and thus fixing the closure part 3 with the housing 2.

It can be seen that the conductor connection terminal 1 is constructed fully symmetrically with respect to a plane of symmetry SE, with the first latching connection 7 being arranged in the plane of symmetry SE. The plane of symmetry SE extends perpendicular to a conductor insertion direction L.
