Description

"Meter board clamp."

The invention relates to a meter panel clamp. Such meter board clamps consist of a base made of insulating material (porcelain or plastic) in which, depending on whether one or more metallic clamps are to be accommodated, separate receiving spaces formed by front and transverse walls are provided. The metallic clamps have a threaded hole in the trough-shaped lower area. A head screw, the threaded shaft of which engages in this threaded hole, engages through a hole in the center of the base. After the current-carrying terminal has been attached, this hole must be filled with a putty-like insulating material due to a VDE regulation : which sets when it hardens. This activity is very costly and consequently makes the entire meter panel clamp more expensive. On the other hand, the insulating material bases have laterally protruding fastening tabs at their two end regions, which are provided with a hole. The fastening is carried out on the distribution rail through this rear-engaging webs, which in turn have threaded holes to accommodate the fastening

have screws. The fastening work, creating the bars and tightening several screws ben, as well as the provision of the metallic webs and the screws make the meter panel clamp more expensive Likewise.

The invention is based on the object of securing the metallic clamp within the Base compartment and / or the attachment of the base to the distribution rail of the meter panel is essential to simplify and so cheaper, that is practical no time is required to carry out these two fastening activities, thus the assembly costs are also reduced. The possibility should also be maintained remain, the clamp body as profile rod sections continue to manufacture.

The invention solves this problem first in that the base is made of an elastically resilient plastic is formed and the end walls or partition walls delimiting the receiving space on the one hand and the side walls of the clamp body facing them, on the other hand, are designed so that they are under grip are that the clamps with a strong impression movement under resilient stress the front or partition walls have a snap-in connection

enter. As a result, there is no need to make a threaded hole in the bottom of the clamp body and its tightening by means of a cap screw passed through the base from below as well as their cementing to the ^ od side. The mere snap of the clamps brings a substantial time savings with it.

It is advantageous if the end and side walls on their sides facing the clamp approximately in medium height have an inwardly directed locking surface and the clamp body at its two, the side faces facing the walls each has a latching projection at approximately mid-height, which is advantageous an inclined performance surface is connected upstream. This special design makes the insertion process favors resilient use of the side and partition walls of the base. This activity is made even easier if the end walls or partitions are above the locking surface have an outwardly inclined threading surface for the clamp towards the edge. the Terminal profile strip does not become more expensive.

Furthermore, the task is set with regard to the fastening of the meter panel clamp to the distribution rail solved in that the base has the recess for the distributor rail on its

the seating surface of a uniformly formed material, broad in cross-section spring, which is provided with a bulge facing the recess.

In a preferred embodiment of the base, the spring is turned away from the attachment point öeite a projection 'is provided, which extends upwards at its free end, while the spring at its free end with an upwardly directed under-grip fastening hook is provided that the projection for the purpose of ver v; tension of the spring with respect to the distribution rail I is able to overlap. The transfer of the spring i in the tension situation is still favored if j the projection on the base at its end face one; i

the tension springs are no less effective than by screws. However, this makes the meter terminal much cheaper.

In the drawing, the subject of the invention is explained using an exemplary embodiment. Show it:

1 shows a longitudinal section through the base, FIG. 2 shows a side view of the base, FIG. 3 shows a plan view of the base according to FIG. 1, FIG. 4 shows a section through the metallic clamp

and Fig. 5 is a plan view.

The base 1 consists of an elastically resilient plastic, with upright end walls 1 ^C or partition walls 1 on the one hand and lateral ribs 1 and a curved bottom part 1 ^a on the other hand receiving spaces for the metal clamping bodies 2 representing profile rod sections . The end walls 1 ° or partition walls 1 and the side walls facing you of the clamping body & on the other hand are designed so that the clamp body 2 engages in a snap-in connection when the front or partition walls are subjected to a strong indentation movement, which is achieved in the exemplary embodiment,

that the end and side walls 1 °, 1 or 1 _f 1 on their sides facing the clamp have an upwardly directed locking surface 1 at about mid-height, which runs parallel to the seating surface of the base, it has clamp body 2 here on both of its, the walls 1 ^C , 1 facing side surfaces at approximately mid-height each have a latching projection 2 ^a , which is advantageously preceded by an inclined threading surface 2.
