Description
Technical Field
The invention relates to a potential distribution device for electrical conductors.
Background
Potential distribution devices, which are also often referred to as potential distribution blocks or potential busbars, are frequently used in circuit technology for distributing potentials or for placing electrical conductors connected to the potential distribution devices at a common potential. For this purpose, the potential distribution devices known from the prior art generally comprise a plurality of block-shaped elements, including a feed element for receiving one or more conductors having a larger cross section (which is also generally referred to as a feed cross section) and one or more distribution elements for receiving one or more conductors having a smaller cross section (which is also generally referred to as a distribution cross section). The block-shaped elements are usually arranged on a mounting base, for example a support rail.
The electrical connection of the electrical conductors to the potential distribution device is achieved in different ways in the prior art, for example by a screw connection or a clamping connection.
In the devices known from the prior art, the known feed elements and distributor elements are usually connected to one another by means of wire bridges or fixing bridges. DE 102014105316 a1, DE 20220108U 1 and DE 29719177U 1, for example, describe terminal block blocks which are connected to one another by means of terminal blocks arranged in rows. The junction boxes can be connected to one another by bus rails, which can also be referred to as plug bridges, connecting clips, cross connectors or cross bridges.
However, the potential distribution devices known from the prior art have the disadvantage that the user has to stock a plurality of different pieces if a different number of connections and/or connection cross sections are required.
Disclosure of Invention
The aim of the invention is to reduce the variation of elements in a potential distribution device for different applications.
This object is achieved by a potential distribution device having the features of claim 1.
Accordingly, an electrical potential distribution device for an electrical conductor is provided, having:
at least one feed-in element adapted to be electrically connected with a first electrical conductor; and
at least one distribution element adapted to be electrically connected with at least one second electrical conductor, wherein the infeed element has a first plug and the distribution element has a corresponding second plug which can be plugged together with the first plug to electrically connect the infeed element and the distribution element to electrically connect the first electrical conductor with the second electrical conductor.
The potential distribution device may also be referred to herein as a potential distribution block device or a distribution block device, and may be used for distributing or collecting potentials, for example for load current distribution and control current distribution. The electrical conductor described herein may be a flexible electrical conductor equipped with a core end sleeve with or without a plastic sleeve. Alternatively, the electrical conductor can also be of rigid design.
The feed element can have an opening into which the first electrical conductor can be introduced and can be held in the introduced state in order to electrically connect the feed element with the first electrical conductor. For example, the first electrical conductor may feed current into the electrical grid and may have a larger cross-section than the electrical conductor which may be connected to the distribution element. In an example, the feed element may comprise a plurality of openings for connecting more than one electrical conductor for feeding.
The distributor element can also have at least one opening into which the second electrical conductor can be introduced and can be held in the introduced state in order to electrically connect the distributor element with the at least one second electrical conductor. In an example, the distributor element has a plurality of openings for connecting a plurality of electrical conductors for distributing the electrical potential introduced into the feed element.
The plug connection between the first and second plug element may comprise pin-like contacts, for example flat contacts, which may be arranged on the housing of the feed element or of the distribution element. The flat contacts can be introduced at least partially into the openings of the respective other housing and electrically connected with corresponding contacts in the openings. For example, the connection may be established by arranging the two housings alongside one another or moving the two housings towards one another. For example, a contact rocker (kontake) may be configured as a corresponding contact and, upon insertion, may exert a torque in the insertion direction, to which the contact rocker may yield. This can be achieved, for example, by elastic deformation of a spring member, such as a spring element or a spring arm. The inserted plug part can therefore be clamped in the housing and fixed in the axial direction in order to ensure a reliable connection and to make an axial movement of the inserted plug part in or against the insertion direction difficult.
In the plugged-together state of the first plug element and the second plug element, the feed element and the distributor element can be electrically connected for electrically connecting electrical conductors, which can be arranged in the feed element and the distributor element, respectively, and thus for distributing the potential connected to the feed element.
Advantageously, no separate plug-in bridge or the like can be used by the plug-in connection, and the feed current can be transmitted to the distributor element without losses via the aforementioned plug-in bridge or the like.
Furthermore, advantageously, by using the potential distribution device described here with different feed elements and distribution elements, it is possible to plug together the desired conductor cross section and pole number for the desired application.
In one example, the first plug of the feed element and the second plug of the distributor element are arranged on the respective mutually opposite housing sides of the feed element and the distributor element in the mounted state in which the feed element and the distributor element are arranged next to one another for plugging together the feed element and the distributor element.
Advantageously, the feed element and the distribution element, or a plurality of feed elements and distribution elements, can be simply arranged in line with one another by plugging together.
In one example, the first plug and the second plug are designed for a direct and detachable electrical connection of the feed element and the distributor element.
Advantageously, the electrical connection between the feed element and the distributor element can be realized without a plug-in bridge and can also be broken again in a simple manner.
In one example, the contact surfaces are configured to contact the blade and corresponding contact springs.
In one example, the feed element and the distributor element can be adapted for rail mounting, in particular can be fixed to a profile support rail, or can be adapted for direct mounting on a surface by means of an adhesive.
The rails can also be referred to as support rails here for fixing the feed element and the distributor element alongside one another. The support rail can have a hat-like contour and is therefore also referred to as hat rail. For example, the elements can be pushed laterally and plugged together when pushed, or first plugged together and then plugged onto the profile support rail and locked thereon.
Alternatively, the element can also be glued to the surface by means of an adhesive, for example an adhesive strip.
In one example, the distribution element is adapted to be electrically connected to a plurality of electrical conductors, wherein the plurality of electrical conductors includes at least the second and third electrical conductors.
Advantageously, a plurality of different distribution elements can be combined with the feed-in element, which distribution elements can be adapted for electrical connection with a plurality of electrical conductors.
In one example, the first electrical conductor has a larger cross-section than the second electrical conductor,
in particular, the first electrical conductor has at most 16mm2And the second electrical conductor has a cross section of at most 4mm2Cross-section of (a).
As already described above, the cross section of the first electrical conductor may also be referred to as the feed cross section. The cross section of the second electrical conductor may also be referred to as the distribution cross section.
In one example, the feed element and/or the distributor element have a screw connection, a tension spring connection, a push-in connection, a quick connection and/or a latching connection (Bolzenanschlussverbindung) for electrical connection to the first and/or second electrical conductor.
In one example, the potential distribution device has a further distributor element, wherein the distributor element has a corresponding further plug element which can be plugged together with the first or second plug element.
Advantageously, a plurality of distribution elements of the same type or different types can be added to the electrical potential distribution device in order to be able to be combined in a customized manner for a specific application.
In one example, the potential distribution device has a separating element, in particular a switching element or a safety element, wherein the separating element has a corresponding plug element in order to be able to be arranged between the feed element and the distribution element and is suitable for separating an electrical connection between the first plug element and the second plug element.
Advantageously, a separate element can be added to the potential distribution device, which can be embodied, for example, as a mechanical switch or as a fuse holder for a fuse. The separating element can advantageously separate the electrical connection between the feed element and the distributor element in order to prevent adverse operating states, such as overload states.
