Description

1 105423

This invention relates to mounting elements according to the type definition 5 of claim 1 for releasably attaching electrical installation devices to mounting ducts having a longitudinal groove with a nearly T-shaped cross-section at the rear wall. Such an installation element is known, for example, from DE-U-86 09 10 417.

The essential function of these types of mounting elements is to enable fast, secure, durable, yet removable attachment of electrical installation devices to the mounting ducts. While DE-U-86 09 417 refers to only one suitable fastening mechanism, DE-U-77 28 102 discloses such an installation element in the form of a device mounting box having a nearly square bottom surface and a pivotally mounted base extending through the bottom of the box. , a flap mechanism acting as a fastening element. The simplest way of attaching the electrical installation device to this device box was by means of screws.

; v: 25 The tightening machine described in DE-U-86 09 417 ···. The specialty related to Canicism is that opening and. ···. closing requires only a 90 ° rotation and • no need to disassemble the mounting device, at least not as long as • · ... • · · *> # ** 30 can be accessed via the screwdriver slot in the rotation element. However, since the known clamping mechanism consists of several parts, there is a need to simplify the structure without compromising the strength and the safety of the clamping fastener.

2 105423 factory installation can be greatly simplified. In addition, the mounting element should be further developed for the simplest possible installation and disassembly of the actual mounting device, whereby the enclosures of the mounting devices were also adapted accordingly. In addition, it should also be possible to connect multiple cables at the construction site in the shortest possible time without compromising electrical safety.

10 This principal problem is solved by an assembly element according to the species definition having the characterizing part of claim 1.

The essential advantage is that the clamping member, which is pivotally mounted on the bottom of the mounting element 15 and which can be lifted and lowered, consists of only one single part. The 90 "rotation is performed from the front with a screwdriver. During the first half of the rotation, only the tensioning head is rotated; v: in the longitudinal groove of the 25 channels, so that the mounting element · · · · remains in the installation channel but can still be moved laterally and accurately adjusted.

• · «1 · • · ... Like the elements of the prior art, the mounting element of the invention may also be constructed as a device box having two longitudinal walls and two transverse walls, but having a ·· · V base. most preferably rectangular.

: T: The essential extension of the invention in this context is that special transverse cables moved to the same longitudinal 'I1' wall are formed on the transverse walls and then on both transverse walls.

The installation ducts are usually divided into at least two electrically insulated compartments by means of insulating partitions which are mounted in a longitudinal groove in the rear wall of the duct. As a result of the asymmetrically laid cable entry holes, it is then possible to insert cables into the device box from one of the compartments without piercing the insulation formed by the central partition by simply turning the mounting member.

The above mentioned partial task, i.e. simplifying the installation and dismantling of electrical installation devices in a device box, is accomplished by means of a quick connection, whereby a quick connection groove 15 is formed in the longitudinal walls of the device box and a quick connection lug in the housing. Preferably, the quick-connect sockets are constructed to be almost L or T-shaped, and the quick-connect grooves end in the quick-connect openings that extend through the longitudinal walls. In this way, the longitudinal walls of the device box remain in shape with the electrical mounting device 20 in place, so that they cannot flex against the mounting device due to pressure or draw; the mounting device cannot self-detach.

Also shown in the drawing is the middle plane 7 of the installation duct 1. Due to the asymmetric positioning of the cable entry holes 27, depending on the installation direction 10 20, they are located to the left or right of middle 7 depending on which part of the installation duct 1 is to be connected.

The mounting element 20 is shown cut away from its base. Thus, it is possible to detect the actual base member 21, as well as the midsole 70, with a clamping member 50 inserted therebetween, which has been pushed through an opening in the base member 21. Its T-shaped clamping head 51 can be inserted into a longitudinal groove 3 as shown in Figure 4. After rotation of 90®, the 20 clamping heads 51 abut against the walls of the longitudinal groove 3 and clamp the mounting element 20, its feet 23, against the rear wall 2 of the channel. Possible sizing tolerances are smoothed by the flexible structure of the clamping member 50, which will be discussed in connection with the drawings 7-9.

The functions and structure of these will be further discussed in connection with Figures 7-9.

Finally, in Fig. 5, a bearing pin 36 disposed beneath the lid opening 30 in the flap cover 28 which controls the threaded element 81 by means of a screwdriver can be detected if the clamping member 50 is not actuated directly but indirectly through the push rod 80 (Fig. 7). The bearing 10 also has a guide rib 37 around the pin 36 having a stop for the rotation element 81.

Initially, the legs 23 and the central guide arms 15 24 which are in line with the longitudinal groove 3 in the rear wall of the channel 2 can be detected. In addition, a central opening 22 can be observed. It is surrounded by a stairwell 32, which is provided with mounting holes 38, the function of which will be further discussed in connection with Figures 7-9.

These slides 55 extend along the lifting ramps 33 on the inner surface of the base member 21 of the mounting element 20. They convert the clamping member 50 into a rotational movement of the clamping member necessary to effect a clamping connection 5 between the mounting element 20 and the mounting duct 1. The lifting ramps 33 are then configured such that this lifting movement does not begin until after a rotation angle of about 45 °, so that the mounting element 20 is mounted in the installation channel 1 but can still be moved freely.
