Description

The invention relates to an electrical connection and terminal comprising an electrically conductive base body having two opening areas for insertion and holding of electrical conductors and the at least one clamping device for releasably fixing the inserted into the opening areas electrical conductor.

State of the art

Electrical connection and connection terminals are known in various embodiments. They usually consist of a base body, which is metallic and thus electrically conductive. The main body is tunnel-shaped and thus has two opening areas. These opening areas are connected to each other by a through-body in the body cavity. In order to couple two electrical conductors together, the respective stripped free ends of the conductors are introduced either together in an opening area or in each case in the two different opening areas. In order to prevent accidental sliding out, a clamping device is provided. A very simple embodiment of such a clamping device is that extends perpendicular to the longitudinal extent of the cavity at least one screw which penetrates the wall of the cavity and clamps the electrical conductor against the inner wall of the cavity. Characterized in that the electrical conductor is stripped, an electrical line is made with the base body, so that the introduced in the same way other conductor also receives an electrical line to the body and so both conductors are contacted with each other electrically. The main body is usually poured into a plastic shell, so that the body is insulating from the environment.

Disadvantages of the prior art

One of the disadvantages of the previously known from the prior art embodiment is that the clamping force exerted by the clamping device on the electrical lines, sufficient only for small cable cross-sections. Small cable cross sections are to be understood as those which have a cable cross section of up to 5 mm.

In addition, it is difficult to introduce the electrical lines, which usually consists of a plurality of wires, in the very small cross section of the respective opening area.

Object of the invention

Therefore, the object of the invention, a connection and terminal of the above type such that at least one of the aforementioned disadvantages is avoided.

Solution of the task

The solution of the problem is provided by the features of claim 1.

Advantages of the invention

One of the essential advantages of the invention is that the basic body is a very simple component whose clamping device assumes a dual function. On the one hand, a part of the clamping device closes the main body and thus forms the cavity together with the main body. On the other hand, due to its technical structure, the clamping device offers a very high clamping force, so that the electrical conductors within the base body are securely but releasably fixed.

The clamping device consists of the known screw elements and a closing element. The closing element serves to close the essentially U-shaped main body viewed in cross-section such that a cavity is created. To achieve this, the closing element attaches to the respective free ends of the base body, which has a U-shaped cross-section, and there makes an at least positive connection. Another advantage is that the electrical conductors to be picked up can be properly placed in the cavity before the closure member is inserted, so that the cavity can be completely seen by the user.

An embodiment of a positive connection provides that the closing element is designed as a kind of sliding block, which engages in corresponding recesses on the sides of the base body. To close the clamping element, the closing element is attached from one side of the base body and pushed in the direction of the longitudinal extension of the base body until a flush contact is reached to both opening sides. Due to the undercut of the nutensteinschliesselements a positive connection is achieved.

A development provides that an insertion of the closing element in different heights, ie at different distances from the bottom of the U-shaped base body is possible. For this purpose, various receiving areas arranged at intervals are provided, so that the User, depending on the cross section of the respective electrical conductor can select the appropriate position. In order to enable the insertion, a groove oriented in the longitudinal direction is provided at the free ends of the U-shaped cross section of the base body in each case facing the inside of the cavity. This groove is a positive connection with the closing element, in which this is inserted from one side into the groove.

The screw elements are preferably already preassembled on the closing element. For this purpose, the closing element has one or more through holes, which are provided with a thread into which a screw element can be screwed. Once the closing element is positioned in its final position to be clamped, the screw elements are further rotated through the closing element until they contact the electrical conductors and then pressed by further rotation against the inner wall of the cavity.

Further advantageous embodiments will become apparent from the following description, the claims and the drawings.

Description of an embodiment

In the 1 to 5 is an electrical connection and connection terminal 1 shown. This connection and connection terminal 1 consists of a basic body 2 which is electrically conductive. Preferably, this consists of metal. In cross section is the main body 2 U-shaped and therefore has a cross-sectional base 3 as well as two thighs 4 on. This creates a channel-like cavity 5 that to the free ends 6 of the U-shaped body 2 is open. The cavity 5 extends in the longitudinal direction (arrow 7 . 4 ) of the connection and connection terminal 1 ,

In the area of the free ends 6 is a groove formed in the longitudinal direction 8th provided in the at least form-fitting a closing element 9 intervenes. This closing element 9 is designed such that it has the free ends 6 of the U-shaped body 2 connects and thus the cavity 5 closes like a tunnel. The closing element 9 preferably also consists of an electrically conductive material.

Due to the tunnel-like formation of the cavity 5 with inserted closing element 9 arise at the connection and connection terminal 1 two opening areas 10 and 11 , These opening areas 10 . 11 serve to receive the electrical conductors (not shown in the drawings) and electrically connect or couple with each other. Are these electrical conductors in the cavity 5 introduced, they are clamped there. screw 12 perpendicular to the longitudinal extent (arrow 7 in 4 ) are aligned by screwing the cavity 5 downsize and so in the cavity 5 arranged electrical conductor against the inner wall of the cavity 5 Press, so that this tensile strength in the connection and terminal 1 are arranged and the other with each other on the main body 2 to which they are pressed, are contacted. Thus, the closing element forms 9 together with the screws 12 a clamping device 15 ,

The main body 2 is from an insulation body 13 surround. This consists of a non-electrically conductive material. In addition, the screws can 12 with insulation caps (not shown in the drawings) to be occupied.

The insulation body 13 can additionally coupling elements 14 exhibit. These serve to make the one connection and terminal 1 with another connection and connection terminal 1 can be positively and non-positively connected, so that a juxtaposition of connection and terminals 1 can be provided comparable with luster terminals. The coupling element shown in this embodiment 14 is a sliding element, which is groove-like inserted into another sliding element, so that a detachable connection of several connection and terminals 1 can be provided.

For the insertion of electrical conductors in the connection and terminal 1 These are first stripped and then into the cavity either laterally over the respective opening area 10 . 11 inserted or inserted into the cavity from the open side. The user can now make sure that the conductors are arranged appropriately. Subsequently, the clamping device 15 attached in which the closing element 9 in the groove 8th of the basic body 2 is inserted from one side. After proper positioning, the clamps are clamped in the now closed cavity 5 through the screws 12 , These cause the conductors are pressed against the inner wall of the cavity and contact there. The screws 12 Keep this depressed, with the counterforce on the positive connection of the closing element 9 with the main body 2 provided.

The connection and terminal block is suitable for all cross-section sizes of electrical cables, that of the connection and terminal 1 can be included.
