Fig. 6 an arrangement of terminals in series composed of several series terminals mounted in series one next to the other, according to the type of figure 5;

Figure 1 shows a housing 1 with a box 2 of accommodation to accommodate at least one or several module of connection 3 connect electrical conductors (not recognizable here).

Figure 1 shows a housing 1 in the form of frame with a housing 2 to accommodate at least one or several connection modules 3 to connect electrical conductors (not noticeable here).

Accommodation box 2 presents (see Figure 3) a series of cameras 4 located in a row next to each other, among which an intermediate wall 5 has been built here, the which separates cameras 4 from each other. Each camera 4 is designed to accommodate a connection module 3 - figure 2.

According to figure 3, cameras 4 they have an open side 6 that serves to introduce the module connection 3. On its side 7 opposite the insert side 6 are closed by a wall 8 of insulating material that is crossed by a flat contact 9 (for example, a blade contact), which on the one hand it penetrates inside 10 of the corresponding chamber and on the other hand protrudes from the housing 1 of the housing accommodation 2 outwards. According to figure 1, in the housing 1 there is formed a projection 11 that laterally protects the corresponding flat contact 9. On projection 11 which also it is open down you can make contact with the contact plane 9, for example, the conductor can be welded here.

The housing 1 may be constructed of the type shown in figure 1 as a separate housing to be mounted in a main electrical apparatus, for example a contactor, which It has a corresponding "possibility of attachment" for housing 1 or it can also be built as part of a main housing of an electrical appliance, - for example the mentioned contactor. In this case the possibility of build housing 1 and the main housing in one piece - no represented - of the electrical apparatus.

Each of the cameras is provided in their outer sides 12,13 with notches 14,15 used to accommodate embedding the 16.17 hitch projections of the modules connection 3.

The connection modules have a housing 18 of insulating material whose geometry is adapted to the geometry of the 4 chambers. The 16,17 shaped hitch projections laterally in the housing 18 of insulating material of the modules 3 connection allow a secure seat embedded in the modules connection 3 on cameras 4.

Connection modules 3 close preferably or flush with the open faces 6 of the chambers 4 or slightly protrude from them out.

In insulating housings 18 there are built in each at least one or more connection device (s).  The connection devices may be designed according to the desired connection technique, for example, depending on the type of tension spring connection shown in figure 1 with the corresponding openings in the insulating housing for drivers and a screwdriver, but also as a connection screwed, as direct plug-in connection, as contact of cut / tighten (IDC), piercing contact or in any other way that is desired.

According to figure 1, the connection device is built as a connection by traction spring 19 with the corresponding metal parts (tension spring 20, plate of stream 21 etc. and openings 22.23 for the introduction of a screwdriver and a driver). Essential and common with connection devices of any technique chosen is that they end in a contact tulip 24 that is designed for the contact of flat contacts. The insulating housings 18 of the connection module 3 each has an opening 25 in which the free ends of flat contacts 9 embedded in the chambers 4, so that the tulips make contact there.

To comply with the requirements or similar, as needed, the shells 18 of insulating material can be designed closed on both sides of the connection device or open on one or both sides. Depending on the design, under certain conditions, intermediate walls can be dispensed with 5 between chambers 4, which on the other hand are advantageous.

The invention has the advantage that in an apparatus electrical only the possibility of attaching to the apparatus or else a housing for modules, in which a series of flat contacts are provided. According to the application the user chooses the connection technique without the electrical device itself has to be configured for the corresponding technique of Connection.

Figures 4 to 6 show the universality of The application of the modules. According to figure 4, a serial terminal 26 is provided with a housing 2 that is used for Introduction of the modules. The "camera" 4 or the box of accommodation 2 are reduced here to lateral guides 27 or to ribs with the guides 27 that each one presents the notches 14,15, for the insertion projections 16.17. In each terminal in series 26 this built one of the flat contacts 9. One of the terminals in series could also present several of the boxes 2, laterally to the current plate that cannot be appreciated here and on which she can be embedded, and / or present several of the 4 cameras in grouping block shape in the direction of the extension of the current plate.
