Definitions

  • the present invention relates to the field of electrical connection technology. It relates to a screwless terminal according to the preamble of claim 1.
  • Screwless terminals which work with spring clamps in the manner of a cage tension spring, are known in various embodiments from the prior art. Differences arise mainly in the way in which the cage tension spring is actuated, i. is moved against the spring tension of the clamping position in the open position. This can either be done directly with a tool such as a screwdriver, or via various types of built-in actuators.
  • a spring clamp with a cage tension spring is known in which for actuating the spring in the housing, an actuating element (8) is provided in the form of a rocker arm, which is mounted freely in a chamber of the housing. Difficulties arise here in particular during assembly and by the insufficient fixation of the actuating element.
  • a terminal for electrical conductors is known in which the cage clamp is operated directly by a plug-in in a push channel plug-screwdriver.
  • the blade tip of the screwdriver is guided by a molded-on insulating material insulating guide tabs (16).
  • By inserting the screwdriver in the insertion is - especially at large spring forces - a significant force exerted on the underlying mounting rail, which is usually undesirable.
  • a comparable solution is known from DE-Al-196 29 565 and DE-AI-44 13 151 known.
  • DE-Al-196 1 1 762 discloses a screwless terminal with a mounted in an insulating housing clamping spring, which is designed in the manner of a cage clamp and by means of a manually operable, also mounted in the housing actuating element against a spring tension of the clamping spring from a first position in which a cable to be connected is clamped, can be brought into a second position in which the cable in the terminal can be inserted or pulled out of the terminal, wherein the actuating element is pivotally mounted in the housing about a pivot axis and in its actuation about the pivot axis is pivoted, wherein the terminal has a bus bar, which lies with their broad sides parallel to the pivot axis and the clamping spring is arranged on a wide side of the bus bar such that they in the clamping first position the conductor of the connected cable on the opposite broad side against the busbar presses
  • the busbar forms a part of a pivot bearing with a bearing arc formed on it, in which the actuating element is pivotally mounted about the pivot axis.
  • An embodiment of the inventive terminal is characterized in that the actuating element is integrally formed and consists of an insulating material. This results in a good mechanical stability and a safe electrical separation between the tool and clamping spring with a simple design.
  • the means for applying the tool comprise an engaging hole extending in the radial direction into the interior of the actuating element.
  • the engagement hole for receiving the blade of a screwdriver is formed.
  • Another embodiment of the invention is characterized in that the terminal has a passing in the insertion direction through the housing busbar, which lies with their broad sides parallel to the pivot axis, that the clamping spring is mounted on a broad side of the busbar such that they are in the clamping first position presses the conductor of a connected cable on the opposite broad side against the busbar, and that the busbar forms a part of a pivot bearing with a bearing arc formed on it, in which the actuating element is pivotally mounted about the pivot axis.
  • the fact that the mechanically stable busbar forms part of the pivot bearing has the consequence that the forces occurring in the bearing during the actuation of the clamping spring can be safely absorbed and introduced into the housing without difficulty.
  • a cylindrical axis is formed on the actuating element to simplify the construction, wherein the actuating element with the axis in a housing formed on the, approximately semi-cylindrical bearing shell, and the bearing shell forms the pivot bearing together with the bearing arc of the busbar.
  • a passage opening is provided on the actuating element for forming the cylindrical axis through which the busbar extends with its bearing arc.
  • FIG. 1 in the sectional view of an embodiment of the invention, wherein only a half-shell of the housing is shown;
  • Fig. 2 is a side perspective view of the embodiment of Fig. 1;
  • Screwdriver is attached with its blade
  • Fig. 4 reached by tilting the screwdriver of Fig. 3 position of the device in which a cable can be inserted or pulled out.
  • FIG. 1 and 2 an embodiment of a screwless terminal according to the invention is shown in a sectional view and in a perspective side view.
  • the terminal 10 is housed in a rectangular housing 1 1, which consists of an insulating material and is composed of two half-shells, of which only one is shown.
  • a plurality of recesses 12, .., 16 are provided, in which a longitudinally extending through the housing, stable busbar 17, formed as a cage tension spring clamping spring 25 and a pivotally mounted actuating element 21 are housed.
  • One of the recesses, namely the recess 1 5 serves as an insertion opening for a cable to be connected (31 in Fig. 4).
  • the terminal 10 comprises with complete housing 1 1 in total only five items (2 housing halves, the busbar, the Cage tension spring and the actuator), so that there is a very simple and easy to install device.
  • the busbar 17 is largely fixed by the slot-shaped horizontal recesses 1 2 and 14 in the vertical direction. Between the two narrow recesses 12 and 14, it passes through a larger recess 1 3, in the same time the actuating element 21 and the Käfigzugfeder or clamping spring 25 are arranged behind and arranged one above the other.
  • the actuating element 21 extends in the longitudinal direction of a pivot bearing 18, 34 to the highest part of the clamping spring 25, where it rests on the clamping spring 25.
  • the pivot bearing 18, 34 is formed by a lower semi-cylindrical bearing shell 34 which is formed in the housing 1 1, and by an upper semicircular bearing arc 18 which is formed in the busbar 17.
  • the busbar 17 thus forms with its bearing bow 18, the upper end of the pivot bearing.
  • the clamping spring 25 is arranged in a following on the bearing sheet 18 horizontal contact portion 19 on the upper broad side of the busbar 17 so that the busbar passes through the clamping opening 26 of the clamping spring 25. After this Traversing the clamping opening 26, the busbar 17 is in a stepped upwardly bent end portion 20, which allows unhindered insertion of the cable into the insertion opening 15 below.
  • end portion 27 of the clamping spring 25 which dips into the underlying recess 16 upon actuation of the clamping spring 25.
  • an engagement hole 22 extending in the radial direction into the interior of the actuating element 21 is provided, which is designed to receive the blade 30 of a screwdriver 29 (FIGS. 3, 4).
  • the engagement hole 22 extends substantially perpendicular to the insertion direction 35 of the terminal 10 into the interior of the actuating element 21 into it. If, according to FIG. 3, a screwdriver 29 is inserted with its blade 30 into the engagement hole 22 and then pivoted to the right (FIG. 3 -> FIG. 4), the actuating element 21 pivots clockwise about the pivot axis 33 and presses the clamping spring downwardly, FIG.
  • the clamping spring 25 clamps the conductor 32 by means of its spring force and presses it against the lower broad side of the busbar 17 to release the cable 31.
  • the clamping spring 25 can be reopened in the same way to release the clamped conductor 32 to give.
  • the introduced by the screwdriver 29 in the terminal 10 forces are thereby significantly taken up by the stable busbar 17 and introduced into the housing 1 1, that the loads for outside the terminal 10 located parts and devices or apparatus are low.
