Description

The The present invention relates to an optimized connector, which especially serves to electrically free the free ends of at least to connect a power cable pair with each other.

As known, the technology offers extremely many connectors, which also, depending on the specific uses for which they are intended, and especially depending on the voltage and / or current levels that they are safe and reliably transmitted have to, using different principles, techniques and materials getting produced.

Especially the patent US-A-2,931,009 describes a connector in which a conductor cable is connected, for example, by soldering in the central opening of a connecting member made of electrical conductive material and having an externally threaded end. A second power cable is connected in the same way in a central opening with a second connecting element, which is also made of electrical conductive material, the second element has a conical flange on the outside. In addition, an adjusting screw with internal thread has been attached to a second connecting element with its conical flange, through which a corresponding conical collar is secured in the nut, whereby, when the first connecting element is screwed into the nut, the sides of the connecting elements are mutually in abutment. In order to insure the electrical connection between the connecting elements, a locking screw is provided, which is tightened due to the action of the nut to move this nut in a circular manner, so that the second element is pushed to the first element. While this type of connector is effective in guaranteeing power connection between the cable ends, it is apparent that it is not as effective in insuring power insulation, not only making it fundamentally dangerous, but also requiring the use of additional parts In order to isolate the power connection accordingly and therefore to avoid the possible dangers of short circuits or electrocution, so that its production is quite expensive.

Of course, other types of connectors are known, such as those in the patents US-A-2 595 057 and US-A-1 836 480 described. However, these connectors are extremely expensive, difficult to use and not very reliable.

The document US-A-2 294 737 describes, however, a connector whose reliability of the power connection between a first and second connecting element, which are respectively connected to the free ends of a power cable pair is basically ensured by the fact that the two connecting elements, after they have been connected to a nut of the first element, through the the external thread of the second element is fixed, are oval shaped and therefore prevent the mutual rotation of one element in the other. It will be readily apparent that the connector described in the above patent is not only extremely complicated and consequently extremely expensive, but also has a relatively limited number of applications over time, as an excessive number of deformations inevitably make its resulting tightness unreliable.

Also in the patent US-A-3,654,588 The connector described is quite complicated and not very reliable, since the tightness of the connection is guaranteed only by a nut and a corresponding thread, both made of plastic.

The document DE-A-26 44 088 describes a connector according to the preface of patent claim 1.

The The aim of this invention is therefore the disadvantages of the known Eliminate or reduce connectors and optimize them To deliver connectors that are simple and inexpensive, conveniently used can be and works effectively and reliably.

The above and other purposes and advantages of the invention which from the following description will be with an optimized Connector obtained as described in claim 1. early Embodiments and not trivial variants of the present invention form the subject of the dependent claims.

In the pictures the grooved ring becomes 33b shown schematically smooth and preferably cylindrical, but it may also be externally equipped with a knurling, which serves to allow a firmer recording in his suit, or it may be externally shaped like a standard size nut to the suit with a tool enable. Preferably, it is also possible to provide that the tenth fret 28b and the eleventh covenant 35b cooperate by interposing elastic devices, for example by at least one external and coaxial coil spring 37b on the second main body 25b so that the suit of the Nutrings 33b at the first thread 29 the feather 37b compressed and a longitudinal tension on the cooperating threads of the first and second threads 29a and 29b generates and thereby significantly limits the corresponding barrel and thus random openings of the connector 1 for example due to vibrations or shocks prevented.

The optimized connector 1 In accordance with the present invention, for ease of illustration, it has previously been described as if it were intended for the connection of a pair of power cables, but the connector 1 can also be used to simultaneously connect several different power cables.

It is clear that the presence of the first and second insulating bushing 15a and 15b allows, advantageously the first and second carrier body accordingly 25a and 25b be made of any other conductive material such as brass, steel or any other metal, avoiding any risk of short circuiting and / or electrocution, and at the same time making it aesthetically more appropriate than the conventional plastic connectors for any application requiring the visible use of a plastic optimized connector 1 according to the present invention, such as for the installation and power connection of chandeliers or lamps.

It is also obvious that the possibility of the first and second main body 25a and 25b and the groove ring 33b and of course the first and second threads 29a and 29b made of metal, the density of the power connection of the connector 1 and, in general, its resistance to shock and load extremely increased over time and guarantees a fundamentally higher reliability over the connectors that have been offered by the technology so far.
