Power rail with one or more adapters

The invention relates to a power plug rail one or more attachable adapters for plugs, consisting of an elongated body of insulating material, in which two pairs of spring straps parallel and at a distance from the connector pins of the connector and possibly another for one Protective conductors are guided and each pair of spring straps consists of two individual pieces placed on edge in the insulating body and there is a small distance next to each other spring strips, between which each a pin of the plug or for the Protective conductor, a pin of the adapter can be inserted resiliently.

A power plug rail with parallel spring band pairs is known from DE-PS 28 38 371. With this power rail are to accommodate the connector pins, the spring band pairs at intervals with curved connector pin openings provided and inserted in the area of the curved connector pin openings between support ribs in the insulating body. The power connector rail is provided with a cover, which is spaced from the connector insertion openings with connector groove profile pots is equipped.

In this known power supply rail is a socket strip for a certain, through the profile pots specified number of plugs. The spring band pairs are clamped by the support ribs in such a way that the plug-pin openings can only spring between the support ribs jg

and sufficient contact pressure when inserting the |

DE-OS 2 358 895 provides another power plug rail has become known with an attachable adapter for power consumption. The advantage of this power rail is that the adapter can be attached to any point on the power rail so that, for example, a socket can be installed where it is needed.

In the known power connector rail, the spring strips are designed as Jl-shaped profile strips, in the opening of which j the adapter can be inserted with a flat pin. The required contact pressure is provided by the legs of the -Ω- profile is generated. However, the manufacture is one such profile strip relatively complex and expensive.

The object of the invention is to create a power connector of the type specified in the introduction, in which the conductors consist of straight spring strips, which are held together by spring clips and the generate the necessary contact pressure for the connector pins. According to the invention, the object is achieved with a power plug rail of the type described above solved by the measures listed in the characterizing part of the main claim.

The advantage of the invention is that the conductors consist of straight spring strips and are used to generate them of the required contact pressure not to be supported by support ribs for each individual "plug opening" to need. Support ribs only need to guide the spring strips at relatively large intervals within the Power plug rail to be available. The contact pressure is generated by the spring clips when the connector pin is inserted at any point on the power-0 plug-in rail. Furthermore, the inventive training a transfer of the contact pressure to the insulating material of the power connector rail is avoided.

The insertion bevels according to claim 2 facilitate the attachment of the adapter and ensure that the brackets grip around the spring straps on the outside.

T ι

For the mechanical connection of the adapter to the insulating body the power plug rail is used according to claim 3, a latching connection that allows the adapter on the To move the power supply rail.

The advantage of claim 4 is that the spring clips are arranged directly next to the connector pin opening can be.

The advantage of claim 5 and 6 is that the width of the adapter is not greater than the width of the Power connector rail, and the insulating body as an extruded profile can be trained.

An exemplary embodiment of the invention is described in more detail below with reference to the drawing.

j It show:

Figure 1 the back of the adapter,

κ Figure 2 a longitudinal section through the current

p plug-in rail and an adapter.

The power plug rail 3 consists of an elongated, trcgartigen insulating body 4 _? which can be produced by extrusion or extrusion. On the bottom of the insulating body 4, three parallel spring band pairs 5, 6 are supported and guided at intervals by supporting ribs 7. Each spring band pair 5, 6 consists of two individual smooth spring bands 8 set up on edge, the distance between which is less than the diameter of the connector pins 9 of the connector 10.

As can be seen from Figure 2 of the drawing, there are three pairs of spring straps 5/6 available, of which the middle pair of spring strips 6 represents the protective conductor. The side walls 11 of the Isolierstoffkörpers 4 are widened and have a for Groove 12 which is open towards the front and whose side flanks are provided with locking teeth 13.

The busbar 3 is provided with a cover, not shown, which engage in the groove 12 with latching arms. The adapter 14 is designed as a socket adapter and has a cup-shaped connector receptacle 15 with a sunk lying end face 16, which has two pin openings 17. Between the two connector pin openings 17 runs a U-shaped protective contact bracket 18, which has a pin 19 on the rear side, which is inserted into the middle pair of spring straps 6 intervenes.

On the back of the recessed end face 16 spring clips 20 are attached, which the spring band pairs 5,6 grip around fork-like and are U-shaped.

Two spring clips 20 each form a pair of spring clips 21, between which a plug pin opening 17 or the pin 19 is arranged.

As can be seen from Figure 2 of the drawing, the free legs 22 of the spring clip pairs 21 are aligned with the Spring hinge pairs 5,6 aligned and provided with insertion bevels. The clear distance between the free legs is advantageously equal to or smaller than the outer distance between two spring strips 8 of a spring strip pair 5, 6, wherein the connector pins 9,19 are larger in diameter than the clear distance between the spring strips.

The adapter 14 can be mechanically connected to the power plug rail 3 by means of a latching connection. For this purpose are molded from the long sides of the adapter 3 locking arms 23 with locking lugs 24, which are in the Lätigsnute 12 of the rail Let 3 press in.

The power plug rail 3 according to the invention can be produced by the meter in fixed standard lengths.

Another possibility is the power plug-in rail 3 to be made from single pieces that can be plugged together.
