Definitions
- the present invention relates to a slot for a low-voltage switchgear according to the preamble of the patent ⁇ claim . 1
- Such a slot is known from DE 1 095 915 Al.
- a contact apparatus for Her ⁇ serves provide an electrical contact of the insert with a contact element located in the switchgear as a counter-piece ⁇ such.
- a contact element located in the switchgear as a counter-piece ⁇ such.
- Each contact device has on two sides depending on a contact finger and a spring.
- the contact finger is pressed in DE 1 095 915 via a lever mechanism with a push rod against the contact element.
- This lever mechanism is triggered upon insertion of the contact element into the slot. Movable here is the entire lever mechanism.
- the contact element must be pressed into the respective contact apparatus.
- the lever mechanism from the guide with con- tact forms fingers and springs, which can be moved as Gan ⁇ ZES via rollers a mechanical unit.
- DE 195 09 474 C2 describes a slide-in frame with movable contact slides, each comprising sliding contacts. All contact slides are moved over a common bar. To postpone the sliding contacts on a busbar, it requires relatively high forces to tension the springs of the sliding contacts, while the sliding contacts accumulate on the edge of the busbar.
- the fingers are (constantly) biased against a contact strip extending between the fingers, and the fingers together with the associated springs form a mechanical unit which is movable along the contact strip as a whole from a disconnected position to a working position and back.
- the contact strip tapers at its end, so that fingers which move along the strip pivot toward one another under the spring force.
- the contact bar is so long that it extends at ⁇ of the fingers between the fingers of both sides least in the separation position along the entire length substantially ER- stretched.
- the tapered end is thus at the "front" of the respective fingers, and the extent of the taper determines when, upon movement from the disconnected position to the operative position, the contact fingers slide on the side surfaces of the copper bar.
- the mechanical unit may comprise a cage enclosing the springs and contact fingers. Grooves in the fingers allow a recording of the fingers in the cage under the possibility of Quer ⁇ movement of the fingers in the cage and entrainment of the cage upon movement of the fingers.
- the cage slides on the narrow top and bottom of the contact strip.
- a contactor has more than one contact finger on each side.
- to be transmitted stream can includes the contact system on each side of six contact fingers, each two contact fingers are biased by a spring, it means are on each side of Kon ⁇ clock bar three springs, the total of six contact fingers bias. The assembly is performed such that first the contact fingers in each case in the grooves and the springs in both
- the mechanical unit of a cylindrical pin is pushed back and forth.
- the cylinder pin can engage in a recess at the end of each contact ⁇ fingers, z. B. at the level of a contact hump on the finger.
- An inventive insert with a plurality of contact devices can be designed so that each at ⁇ the sides (cylinder) pins in the contact devices eingrei- fen, all pins from a pin header forward and back are feasible. It must then be moved only as a Gan ⁇ zes bar to each move the mechanical units in the contact devices in motion.
- the contact devices are then in a housing with two slots for fürse the cylinder pins.
- FIG. 1 shows a plan view of an insert for a low-voltage switchgear according to the invention
- FIG 2 shows a section through the FIG 1 according to the line H-II
- FIG. 3 shows a section through a contact apparatus according to the invention in the disconnected position, 4 shows the section IV-IV in FIG. 3,
- FIG. 6 shows the contact apparatus according to the invention from FIG. 3 shortly before the working position
- FIG 10 shows a side view of the contact apparatus of FIG 9 and
- FIG. 11 shows a front view of the contact apparatus of FIG. 9.
- FIG 1 A shown in FIG 1 in plan view in section slot for a low-voltage switchgear, which be as a whole with 10 ⁇ distinguished, here 12, includes eight contact apparatus, the contact apparatus 12 are shown in the working position in which, for example, a contact to a copper bar 14 or to a copper strip 16, which has an H-shaped cross-section.
- the contact devices 12 are shown as a whole in the same plan view in FIGS. 3 and 6.
- Each contactor 12 has fingers 18 and springs 20. As shown in FIG 4, which is a sectional view of 3 along the line IV-IV, each contact apparatus has a contact strip 22 to be seen in FIG. 3, which may consist of copper, and on both sides thereof, in each case six fingers 18 and three springs 20. Here are two fingers 18 on top of each other and are pressed by an associated spring 20 against the contact strip 22.
- 18 have their fingers every two con ⁇ tact hump 24 and 26 with which they rest on the contact strip 22nd
- the fingers in front ie at the point where the electrical contact is generated, a mushroom-like thickening 27 on.
- the fingers 18 form a mechanical unit with the springs 20 in that in each case six of the fingers are surrounded to one side of the contact strip 22 by a cage half 28.
- Each cage half has approximately the size of half a cuboid and is held on grooves 30 and 32 in the fingers 18.
- FIG. 6 The mechanical unit of the fingers 18 with the springs 20 in the cage 28 is now of the separation position shown in FIG 3, in which the fingers are enclosed in a housing 34 fixedly connected to the insertion frame (10), in a in FIG shown displaced position in which the fingers protrude from the housing 34.
- the position shown in FIG. 6 is a position shortly before the working position, which is shown in FIG.
- To move this mechanical unit of the elements 18, 20 and 28 are cylindrical pins 36, which are best seen in FIG 4, wherein FIG 5 is a sectional view through the contactor 12 along the line VV in FIG.
- the cylindrical pins engage in a recess 37 at the level of the contact bump 26.
- These cylindrical pins are slidable along a passage slot 38 in the housing 34.
- the contact bosses 24 and 26 to slide 22, along the contact bar, the contact bar 22 is at its ten of the opening of the housing 34 face towards ⁇ side tapered easily formed and has a Abschrä ⁇ supply 40.
- the front contact bosses 24 slide along the ⁇ ser chamfer, whereby it comes to that, the fingers that 18 on either side of the contact strip to move towards each other, whereby they slide open during this pivoting motion to the Kup ⁇ ferschiene 14, so as shown in FIG 9 Ar ⁇ shown beits sued to obtain. In this position, the contact hump 24 is lifted from the contact strip 22.
- FIG. 1 The mechanism by which the cylindrical pins 36 are moved is shown in FIG. 1: two racks 42 running transversely in front of the insert are engageable by a pinion 44, which can be engaged with a key at the location of the arrow 45 via the front side; can be moved to the side and over Eckumlenkept 46 strips 48 are moved forward or backward.
- a likewise transverse bar 50 which is the carrier of the cylindrical pins, then moves just ⁇ if from back to front and vice versa, and on the guided with ⁇ cylindrical pins , the contact fingers 18 can be moved from the working position shown in the disconnected position and back.
- the contact strips 22 can be seen particularly clearly in the sectional view according to FIG. 2, wherein in the present example case of eight contact devices 12, for example, the right four contact strips for current drainage from the lower Voltage switchgear and the left four contact ⁇ shown shown can serve to supply power to the low-voltage switchgear.
- the individual contact devices 12 are compact. Of the
- each contact apparatus 12 comprises at least four and a maximum of twelve contact fingers 18, two to six on both sides of the contact strip 22 and two to six springs in the cage halves 28, so that the one transmitted by the contact fingers 18 Current is determined by the number of fingers.
