Definitions
- Connection block for connecting an electrical conductor and device with an external busbar section and a connection module
- the invention relates to a terminal block for connecting an electrical conductor by means of spring clamp to an external busbar piece, which is not part of the terminal block.
- the invention also relates to a device with an external busbar piece and such a connection block, which is plugged onto the external busbar piece.
- spring-clamped conductor terminals which have a complete contact insert with a clamping spring and a busbar piece, such as e.g. described in DE 10 2013 101 406 A1.
- the bus bar piece is part of the conductor connection terminal, i. permanently disposed at least partially within the conductor terminal, so that at any time a terminal point on the busbar piece within the Lei teran gleichklemme is present, to which an electrical conductor can be clamped by means of a clamping leg of the clamping spring.
- the invention is based on the object of enriching the technical field of conductor connection technology by means of spring force clamping by an advantageous new variant.
- connection module for connecting an electrical conductor by means of spring clamped to an external busbar piece, which is not part of the connection module, with the following features:
- connection module has at least one clamping spring and an insulating housing which at least partially surrounds the clamping spring
- a clamping point position is present, formed at the one clamping point for clamping the electrical conductor to the external busbar piece by means of a clamping leg of the clamping spring is when the external busbar piece is connected to the connection module,
- the insulating material housing has a conductor insertion opening, which makes it possible to introduce the electrical conductor to be clamped by means of the clamping leg to the clamping position position,
- the insulating housing has a busbar insertion opening, which allows insertion of the external busbar piece to which the electrical cal conductor is to be clamped by means of the clamping leg, to the nip position.
- the insulating housing has defined insertion openings for the electrical conductor and the external busbar piece, so that these two elements can easily reach the terminal position and are electrically contacted there by the clamping leg connecting the electrical conductor to the external conductor Clamp the busbar piece.
- the clamping point can thus be formed between the clamping leg and the external busbar piece when the external busbar piece is connected to the terminal block.
- connection module can be provided very easily and inexpensively.
- the connection module can only be provided with the components insulating housing and clamping spring.
- the insulating material consists of an insulating material, such as plastic.
- the insulating material housing can be provided as a plastic injection-molded component.
- the terminal block can be formed easily and inexpensively with respect to the insulating material housing.
- no heavy and expensive metal frame is required.
- the connection module itself is not electrically conductive in contrast to the prior art. Only when the connection module is attached to the external busbar piece is it possible to produce a conductive contact between an electrical conductor accommodated in the connection module and the external conductor rail section.
- the smallest possible pitch can be constructed depending on the conductor cross-section, since the outside diameter of the insulating jacket of the electrical conductor to be connected itself determines the pitch and can form part of the outer wall of the connection module.
- the recesses of the insulating material housing as well as the entire terminal block can be shaped so that an introduction and / or insertion of printed circuit board fingers as electrical conductors is also possible.
- connection module can have different mounting options, which allow a flexible design and flexible packaging.
- the connection module can be used in any way, e.g. for potential distributors, feed-through terminals, industrial connectors.
- the terminal block can also have its own busbar or a busbar piece, which is or is the part of the terminal block, but not in such a way that thus the terminal point is formed for clamping the electrical conductor.
- connection module is formed without a current rail.
- connection module does not have its own busbar or busbar section at all. This too is conducive to a simple and cost-effective design of the connection module.
- the external busbar piece may for example be formed like a tongue or have such a tongue that can be inserted into the busbar piece insertion opening.
- This tongue can be formed in example similar to a contact pin or a flat blade contact of a connector.
- the terminal position can be a single, well-defined location in the insulating housing, or a certain defined area in the insulating housing, for example, a tolerance range during insertion of the external busbar piece with which the terminal point can be formed.
- the clamping point position is defined by the shaping of the clamping spring, by the shaping of the insulating material housing and / or the arrangement of the clamping spring in the insulating material housing.
- the clamping position is determined by the position of the clamping leg and in particular the position of a clamping edge of the clamping leg, which can be arranged at the free end, at least in a certain range.
- the shape of the insulating housing in particular the position of inner walls and / or the first and second abutment surfaces explained below, defines such a clamping point position, as well as the position and arrangement of the conductor insertion opening and the busbar insertion opening.
- the clamping spring e.g. the clamping legs, operated by an external tool, e.g. through a screwdriver.
- the terminal block as an additional component has an actuating element, in particular an actuating lever or an actuating lever with which the clamping leg of the clamping spring is deflected by manual operation to open the nip.
- an actuating lever in particular an actuating lever or an actuating lever with which the clamping leg of the clamping spring is deflected by manual operation to open the nip.
- the connection module already has its own operating possibility for opening the clamping point, namely the actuating element, which is thus part of the connection module.
- an actuation lever it can, for example, be linearly displaceable in the Be stored insulating material.
- the water can be stored, for example, pivotably in the insulating housing.
- the insulating material housing has a first contact surface, on which the external busbar piece can be applied.
- the external busbar piece can in particular with its side facing away from the clamping point, i. the side on which not the electrical conductor rests on the external busbar piece, can be applied to the first contact surface.
- the insulating material housing has a second contact surface on which an attachment tongue connected to the external conductor rail piece can be applied.
- the insulating material housing can be designed so that only one of the first and second contact surfaces with the respective counterpart, i. either the external busbar o- or the tongue, can come to rest.
- the second contact surface may e.g. be designed as a first bearing surface opposite bearing surface.
- the external busbar piece may, for example, be designed like a contact tongue or have such a contact tongue.
- the external busbar piece may also have the tab, i. be formed in one piece with the investment tongue.
- the tongue can also be part of another component than the external busbar piece.
- the clamping spring has an abutment leg, via which the clamping spring can be supported against the force of the clamping leg, wherein the abutment leg is supported on the tongue, when the external busbar piece connected to the associated terminal tongue with the terminal block is. In this way, the clamping spring can be clamped between the bearing tongue and the external busbar piece, so that essentially no spring force is transmitted to the surrounding insulating material housing. If an electrical conductor is clamped at the clamping point, the clamping spring is supported on the side of the
- the connection module has an over-housing which surrounds at least a part of the insulating housing.
- the over-housing can be offered as an optional extension to the connection module so that the user can select, depending on the application, whether the connection module is used with or without an over-housing.
- the insulating material can be realized, for example, very material-saving, whereby in certain applications, however, may not be sufficient insulation against the current-carrying elements is present.
- the additional use of the housing, the terminal block can be upgraded to meet such requirements.
- the over-housing may e.g. be connected via locking elements with the Isolierstoffge- housing.
- the minimal formation of the insulating housing makes it possible to achieve a high packing density of adjacent connection components, since the pitch can be reduced to adjacent insulating material housings.
- the outer housing a conductor stop for the electrical conductor to be clamped is formed and / or for an increase in the mechanical strength of the connection block and / or for the production of predetermined creepage distances and clearances.
- the connection module can be optimized to the desired application at the user's discretion and with little effort.
- the insulating housing has one or two recesses arranged on opposite side walls and extending in the conductor insertion direction, in which an insulating jacket of an electrical conductor clamped on the clamping point can be placed.
- an insulating jacket of an electrical conductor clamped on the clamping point can be placed.
- Clamping spring is formed. This also allows the advantages explained above to be realized.
- the plant leg is supported on the tongue.
- Figure 1 - a connection block in side view
- FIG. 2 shows the connection module according to FIG. 1 in the viewing direction A and
- FIG. 3 the terminal block according to Figure 1 in the direction B and FIG. 4 shows the connection module according to FIG. 1 in the viewing direction C.
- connection module 1 shown in the figures has an insulating housing 2 and a clamping spring 4 arranged at least predominantly within the insulating housing 2 and an actuating element 5 designed as an actuating lever in this case.
- the insulating material housing 2 has a conductor insertion opening 20, through which an electrical conductor in a conductor insertion direction L can be introduced into the insulating housing 2 and can be guided to a terminal position 26 explained in more detail below.
- the latter On the side of the insulating housing 2 opposite the conductor insertion opening 20, the latter has a busbar insertion opening 27, through which an external busbar piece 30 can be inserted into the insulating housing 2 and can likewise be led to the clamping position 26.
- the insulating housing 2 also has a first contact surface 21, against which the external busbar piece within the insulating housing 2 can abut it.
- the insulating housing 2 also has a second contact surface 22, on which an abutment 31 connected to the external conductor rail piece 30 can come into contact with the insulating material housing 2 within the insulating housing 2.
- the insulating housing On the side of the conductor insertion opening 20, the insulating housing has a test pin opening 23, e.g. between the conductor insertion hole 20 and a manual operation portion 50 of the operation member 5. Through the test piece opening 23, a test pin can be inserted and brought into contact with the clamp spring 4, e.g. on the spring bow 42.
- the insulating housing 2 has recesses 25 on respective side walls, which may be formed in the form of a longitudinal slot which extends in conductor insertion opening L.
- the recesses 25 may begin at the conductor insertion opening 20 and may extend a distance along the sidewalls, eg, over a range of 20% to 50% of the length of the insulating housing 2 as measured in the conductor insertion direction L.
- the recesses 25 also allow to introduce an electrical conductor with a large cross-section, so that the conductor insertion opening 20 is practically filled and the insulating jacket of the conductor extends into the recesses 25. In this way, a connection block with the lowest possible pitch is realized.
- the external busbar piece 30 may be part of a busbar 3 extending predominantly outside the insulating housing 2, e.g. in the form of a bent out of the busbar 3 contact tongue.
- the tongue 31 may be part of this busbar 3, for example, also in the form of a bent out of the busbar 3 tongue.
- the busbar 3 with the external busbar piece 30 and the extension tongue 31 is shown only in FIG. 1, FIGS. 2 to 4 do not show this external component for the sake of better clarity.
- the clamping spring 4 has an abutment leg 40, which ends at a free end of the clamping spring 4 with a fixing tongue 41.
- a ladder-shaped ramp-shaped Ladereingar auxiliary element 24 may be arranged in the conductor insertion L, the example, as one piece with the insulating material 2 may be formed. Through the conductor insertion auxiliary element 24 a constructive electrical conductor is even better guided to the terminal point 32.
- the actuating element 5 has the manual actuating region 50, for example in the form of a lever handle, from which the actuating element 5 extends over two side cheeks 51 over the insulating material housing 2 and at least partially surrounds it.
- On the side walls 51 is respectively on the inside, ie on the side facing the clamping spring 4, a spring driver 52 arranged, for example integrally formed thereon. If the actuating element 5 is pivoted counterclockwise with respect to the position shown in FIG. 1, the clamping leg 43 is deflected upwards by the spring drivers 52, so that the clamping edge 44 is lifted off the external busbar piece 30 and moved away. In this way, the clamping point can be opened, so that a clamped electrical conductor can be removed or an electrical conductor to be clamped can be easily inserted.
- the clamping spring 4 is on the side of the clamping leg 43 on the external
- Busbar piece 30 superimposed, either directly, if no electrical conductor is clamped, or indirectly via the electrical conductor when it is arranged at the nip 32.
- the clamping spring 4 is supported on the tongue 31, e.g. through the fixing tongue 41.
