Definitions
- the invention relates to a screwless terminal which can be used in devices for installation technology, for example in line circuit breakers, residual current circuit breakers, terminal blocks or sockets.
- the terminal works in principle with a releasable clamping spring, which connects a conductor to be connected under its spring force to a busbar m, in detail according to the preamble of claim 1.
- Such screwless clamps are also called cage clamps or “cage clamps”.
- the live clamping spring is generally directly pressed down with a suitable object, for example a screwdriver.
- a suitable object for example a screwdriver.
- an insulated tool is required in order to be able to remove a connected conductor from a screwless terminal.
- each wire is usually m clamped in its own connection process and, if necessary, detached again.
- a screwless terminal for several potentially isolated conductors chen while ermögli ⁇ even kammformige male parts have been provided.
- it is necessary that the actuation side is accessible over a large area.
- the invention has for its object to develop a screwless terminal that is more convenient to use and that allows easy-to-use multi-pole terminals.
- ⁇ is a sliding wedge-shaped loose element with the clamping spring or with a loose piece in its loose direction. per m active connection.
- the loose body can be manufactured in a simple manner from insulating material, so that safety is guaranteed. A loose piece can be selected for good sliding properties.
- the sliding loose body or a loose pressure piece can be designed as two wedges which can be moved relative to one another.
- a suitable choice of material it is easily possible to achieve good sliding properties. Pressure is exerted on the clamping spring by a stationary part, so that canting with the clamping spring is excluded.
- a sawtooth-shaped loose body can be used to spread the clamp springs of the adjacent clamps at the same time via a sawtooth-shaped pressure piece.
- connection opening of the assigned terminal With the loose body, a partitioning point for the connection opening of the assigned terminal can be connected in such a way that the connection opening is largely or completely closed without a connected conductor.
- FIG. 1 shows a series of three screwless clamps which work together with a loose body and a loose pressure piece, in the form of two sawtooth-shaped wedges which can be moved relative to one another.
- FIG. 2 shows the clamp according to FIG. 1 seen from the side, with the head of the actuating plunger removed
- FIG. 3 shows the clamp according to FIG. 1 in the open state of its clamping springs.
- FIG. 4 shows the side view in the representation according to FIG. 2 the clamp according to FIG. 3.
- FIG. 5 shows a loose body and a loose pressure piece, formed from two mutually displaceable wedges m saw tooth formation, with a flattening being provided at the end of the spreading displacement distance.
- FIG 6 a Losekorper of two against each other is displaceable ⁇ union wedges m sawtooth formation according to FIG 5 is shown for the lots position associated clamping springs.
- FIG. 7 shows a loose body and a loose piece made of two wedges that can be displaced relative to one another in a sawtooth formation in the manner of the representation in FIG.
- FIG. 8 shows the side view of a terminal according to FIG. 7, with a partitioning point for the connection openings, as shown in FIG. 4.
- the screwless clamp according to FIG. 1 has three clamp springs 1 in series, each of which connects a conductor 2 to be connected under spring force to a busbar 3, perpendicular to the plane of the drawing. Also compare FIG. 2. With the clamping spring 1 or with a loose pressure piece 4, a sliding wedge-shaped loose body 5 m is connected in the loose direction. For three adjacent clamping springs 1, the wedge-shaped loose body 5 and the associated loose pressure piece 4 have the formation of a sawtooth. The alsglei ⁇ tend Losekorper 5 and an associated pressure lots stucco 4 are designed as two mutually displaceable wedges, each having the formation of a forecast tooth. For a series of screwless terminals, a sawtooth-shaped loose body 5 is in a spreading operative connection via a sawtooth-shaped loose piece 4. The loose body 5 can be actuated from the side by a plunger 6.
- FIG. 2 it can be clearly seen how a clamping spring 1 is pressed down into position 15 when the loose body 5 and loose pressure piece 4 are spread apart m the delicately drawn position. This, compare the figures 1 and 2 ent ⁇ speaking Figures 3 and 4 for the clamping springs 1 m down its printed position.
- the loop-shaped clamping spring 1 in which one leg 7 is inserted through a window 9 of the other leg 8, this window 9 is released under pressure by the loose body and the loose pressure piece with its lower edge in the leg 8. You can then pull off a conductor 2 or easily insert it.
- the lower edge 10 according to FIGS. 2 and 4 can generally be referred to as the outer edge of the window 9.
- the windows 9 are shown when the conductor is not inserted, with the opening of the window 9 n of the clamping spring for clarity is shown how an introduced conductor would stop it.
- the loose body 5 and the loose pressure piece 4 according to FIG. 5 are provided with a flattening 11 in the end region of their spreading displacement distance, as a result of which clamps can be held in their open position in the position according to FIG. 6 without the wedge-shaped surfaces being able to slide back under the force of the clamping springs.
- loose body 5 and loose pressure piece 4 can be designed to be latching in the end region of their spreading displacement distance in order to achieve an open position of the clamp until the plunger 6 is actuated again.
- the bulkhead 5 is a bulkhead part 12 for the connection opening 13 of the associated terminal m connection.
- the partitioning part 12 can largely close the connection opening 13 when the conductor 2 is inserted during a movement perpendicular to the plane of the drawing according to FIG. 8, and can be shifted so far without an inserted conductor that the connection opening 13 is closed. Understandably, it is advisable to manufacture the bulkhead part from insulating material. Separate partitioning points can advantageously be provided for several terminals.
- the bulkhead parts for the loose body can advantageously be resiliently connected.
- a screwless clamp of the type described has, inter alia, the following advantages:
- the actuation of the terminal can be operated from the front in a row of housings with a multi-level terminal arrangement, as is common with terminal blocks. It is no more space is required for aids for Actuate the ⁇ the clamping spring supply required, so it's a loose-emgriff no access kept clear. Short assembly times can be achieved with aligned terminals by simultaneously operating several terminals.
- the clamping springs can be completely insulated with regard to the actuation side and there is no need to isolate an aid since this is not required anyway. If necessary, the clamp can simply be designed in such a way that stable opening is achieved.
- the clamped state can easily be made visible by the position of the loose body or by the position of an ice cream.
