System of interconnectable connectors

10

The invention relates to a system of plugs that can be joined together according to the preamble of claim 1.

The invention described here belongs to the group of technical connectors intended mainly for the automotive sector and whose purpose, thanks to their external and internal design, is to serve as connection points between female connectors attached to cables entering through the lower part of the connector and male connectors passing through the upper part of the connector and fixed or attached to the ends of other cables. Such a connector therefore serves to centralize in an orderly manner the connection of said cables provided at their ends with the corresponding male and female connectors, by means of prismatic cavities located in the connector.

The connectors available on the market essentially meet the need for centralizing cables, being divided into different types, which have two, three or six cavities inside, as well as elements that serve to fix the connectors in the housing that surrounds them. There are also elements that connect two connectors.

The variety of connector models required due to the centralization of the conductors requires high investments in molds used to form these types and models, which are used in a given electrical installation in different versions and systems.

The object of the present invention is to create a system of pluggable plugs the designs of which are similar to one another and which only differ in the number of internal cavities, the plugs being constructed in such a way that, in order to obtain an even number of such cavities, all plugs can be combined using three individual types which have two, four or eight cavities respectively. This object is achieved according to the characterizing part of claim 1.

The newly designed connectors, in addition to having the internal cavities described above and serving the above-mentioned purpose, have a fastening arrangement and arrangement for mutual assembly and other already known systems which, if necessary, serve to introduce the connectors into the corresponding connector housings.

To bring the plugs together, one of the opposite side surfaces has a groove and a projection, both of which run parallel to the edges or larger surfaces provided with elements for fastening the plugs together. These elements are formed by elastic tongues, in the upper part of which projections are arranged which, in combination with lugs provided on one of the opposite sides, serve as a means of fastening.

Further details and features of the invention emerge from the following description in conjunction with the drawing, in which various embodiments of the system of plugs that can be joined together according to the invention are shown schematically.

The reference symbols used in the description and drawing mean: 10 plug, 11 prismatic shape, 12 upper base, 13 anchoring elements, 14 cavities, 15 lower base, 20 anchoring and connecting elements, 23 longitudinal projections, 24 larger side surfaces, 25 smaller side surfaces, 26 longitudinal grooves, 28 tongues, 29 projections, 30 nose, 31 inclined surface;

In the drawing show:

Fig. 1 is a perspective side view of the connector system consisting of individual connectors with either 2, 4 or 8 cavities and

-3-

Fig. 2 shows, on a larger scale, a perspective side view of two plugs with four or two cavities connected to one another by connecting and fastening elements.

The plug 10 or 19 shown in Fig. 1 and Fig. 2 has a clearly prismatic shape 11, in which a longitudinal projection 23 extending from the upper base surface 12 of the plug 10 to the vicinity of its lower base surface 15 and a longitudinal groove 26 extending in the same way are provided on the smaller side surfaces 25, and on the front, smaller side surface 25 there is alternately a longitudinal projection 23 opposite a longitudinal groove 26 and a longitudinal groove 26 opposite a longitudinal projection 23.

As can be seen from Fig. 2, the anchoring and fastening of two plugs 19 with a different number of cavities 14 consists of tongues 28 extending from the central region of the smaller side surfaces 25, on the sections of which close to the upper base surface 12 there are projections 29 which rest on lugs 30 which are arranged for this purpose close to the upper base surface 12 on the above-mentioned smaller side surfaces 25.

According to the system described here, the mating of two plugs 19 is achieved by, as can be seen in Fig. 2, a longitudinal projection 23 present on a smaller side surface 25 engaging in a longitudinal groove 26 arranged on the smaller side surface 25 of the plug to which the first plug is to be connected.

The special design of the plugs 10 makes it possible to obtain an indefinite number of cavities 14 by combining three different types of plugs 19, each with two, four or eight cavities, thus eliminating the need to use other plugs and achieving great savings in the molds required to manufacture the plugs.
