Definitions

• the invention relates to a connection device according to the preamble of claim 1.
• connection device is already known from DE-195 04 013 C1 (see in particular FIGS. 13-16).
• the object of this device is above all a reusable tap on continuous multi-core cables, preferably on two-core profiled ribbon cables (ASI cables) with current-carrying strands, e.g. for measurement purposes at different points on the ASI line.
• ASI cables profiled ribbon cables
• the construction of the known connecting device for a connecting device is complex, in particular due to the different connections of the continuous and branching line.
• the contact elements to be equipped with both penetration skewers and an insulation displacement terminal are complicated parts which, moreover, have to be guided very precisely in order to enable simultaneous contacting of the wires of the ASI and branch line. But even under this condition, no safe installation and function is guaranteed, because the wires of the branch line are not safely guided and their position when inserting the contact carrier can be checked when using transparent material, but can easily deviate from the target position .
• the necessary supports for supporting the wires of the branch line represent an additional effort.
• the known device for receiving electrical devices such as connectors in the branch connector is neither provided nor suitable.
• connection device is also not suitable for setting up connection structures by joining several identical devices, but at most for connecting two ASI lines if the branch line at the free end is not an actuator or sensor, as provided in column 6, lines 13-14 of the patent specification has, but inserted via a further PG screw connection in the threaded connector of a second connection device according to Figures 13-16 and is electrically connected therein with an ASI line.
• the object of the invention is therefore to provide a connection device of the type mentioned which is as simple and inexpensive as possible and which provides a secure mechanical and electrical connection of the wires of at least two cables to be connected and of cable wires with contacts of plug connectors arranged in the threaded connector of the connection device and with others Connection devices possible.
• the conductor holder enables simple, inexpensive and, above all, positionally stable positioning of the conductors in the connection device for absolutely secure contacting with the contact elements inserted transversely thereto, and thus quick and safe assembly. To do this, the conductors must first be inserted into the bores of the conductor holder and this unit into the threaded connector provided, and then the contact elements must be pressed in through the recesses running transversely to the bores. A visual inspection is not necessary, since the conductors and contact elements are guided on all sides.
• the conductors can advantageously be both conductor cores and metal parts adapted to the requirements of the respective application.
• the connecting device is suitable for both round and flat cables.
• the contact elements can be constructed in an uncomplicated manner and, if piercing spikes are omitted, can be designed both for the contacting of strands and of solid conductors.
• connection device can also be designed and manufactured more simply because no supports are required as a support to be contacted.

In practice, this is limited by the maximum permissible dimensions of the connection device, but with a construction suitable for many applications, at least four threaded connections are possible, a favorable compromise being achieved between the device size and the number of possible connections.
• connection device is suitable as a module for the construction of any connection structures.
• connection devices For this purpose, only the connections of at least one threaded connector of several connection devices are to be connected to one another. Together with the internal connections of each connection device, complex connection networks can be set up that can be optimally adapted to the circumstances of each individual case and which can also be changed or expanded at any time.

• the contact elements can optionally be designed as pins or skewers which can be inserted between the sheets or as legs comprising the sheets, for example insulation displacement contacts.
• a mixed version of the contact elements is of course also possible
• a design of the contact elements according to claim 4 is particularly advantageous because the reliable contacting is largely independent of the type of conductor.
• insulated or non-insulated strands, solid wires or other resilient or rigid metal parts in the contact area are equally suitable.
• connection device A particularly quick and uncomplicated assembly of the connection device is achieved according to claim 5 in that the conductor holder - regardless of the device to be connected - are identical. This not only eliminates the need for an assignment to the various facilities, but also the provision and storage of different ladder holders.
• an embodiment according to claim 6 offers the advantage of small dimensions of the housing due to shorter threaded connections and moreover of the cross section of the connection plug, since the contact elements can be arranged in a narrower space .
• the possibility of overlapping depends on the number of conductor holders and the contacts per conductor holder. Such a design for up to four threaded sockets with two-pole connections can be easily implemented with reasonable effort.
• a possible implementation of this coding is specified in claim 8.
• it has the additional advantage that a projection is formed without additional effort, which can be used as a stop when the conductor holder is inserted into the threaded connector.
• the flattened areas also provide effective anti-twist protection.

• a very substantial simplification of the assembly is achieved by a clamping element effective in each channel.
• the cable wires can first be inserted into the channels and this unit can then be inserted into the associated threaded connector in any inclination position without fear of the conductor holder sliding out of the conductor ends or special tools being required to prevent such a sliding out. Rather, due to the slight clamping of the cable cores, the unit mentioned is preassembled and can also be used in the threaded connector without any problem if this is done from top to bottom.
